PART I

Item 1. Business

Company Overview

We are one of the world’s leading online marketplaces for connecting design lovers with many of the best sellers and makers of vintage, antique, and contemporary furniture, home décor, jewelry, watches, art, and fashion. We believe we are a leading online marketplace for these luxury design items based on the aggregate number of listings on our online marketplace and our Gross Merchandise Value (“GMV”). Our sellers, who undergo an evaluation by our in-house experts to vet the integrity of their listings, in-depth marketing content, and custom-built technology platform create trust in our brand and facilitate high-consideration purchases of luxury design items online. By disrupting the way these items are bought and sold, we are both expanding access to, and growing the market for, luxury design.

Our online marketplace seller stock value, the sum of the stock value of all available products listed on our online marketplace, was consistent year over year and exceeded $10.0 billion as of both December 31, 2024 and 2023. An individual listing’s stock value is calculated as the item’s current price multiplied by its quantity available for sale. As of December 31, 2024, we had approximately 5,900 unique sellers, compared to approximately 7,800 unique sellers as of December 31, 2023. In 2024, we shifted our seller acquisition strategy and monetization approach to concentrate on fewer, but more highly engaged sellers. We discontinued the pricing option with no monthly subscription fees and higher commission rates during the year which contributed to the seller churn.

We provide our sellers, the vast majority of which are small businesses, access to a global community of buyers and a platform to facilitate e-commerce at scale. Our sellers use our platform to manage their inventory, build their digital marketing presence, and communicate and negotiate prices directly with buyers. We provide our buyers a trusted purchase experience with our user-friendly interface, dedicated specialist support, and our 1stDibs Promise, our comprehensive buyer protection program outlined in-depth below. The uniqueness, diversity, and high quality of the items on our online marketplace, together with an active marketing effort, have produced a large global base of design-loving buyers. We operate an asset-light business model which allows us to scale in a capital efficient manner. While we enable shipping and fulfillment logistics, we do not take physical possession of the items sold on our online marketplace.

During the year ended December 31, 2024, we had approximately 64,300 active buyers, compared to approximately 61,000 in the year ended December 31, 2023, who are buyers who have made at least one purchase through our online marketplace during the 12 months ended on the last day of the period presented, net of cancellations (“Active Buyers”).

We had an on-platform average order value (“AOV”) of approximately $2,500 and $2,600 in the years ended December 31, 2024 and 2023, respectively. We had a median order value (“MOV”) of approximately $1,200 in both the years ended December 31, 2024 and 2023. We do not focus on AOV or MOV as key metrics in evaluating our business given our priority to make unique, high-end design items available across various price points through our online marketplace. The percentage of Active Buyers who make more than one purchase in any given year has been generally consistent from year to year and comprised approximately 30% of total Active Buyers in each of the years ended December 31, 2024 and 2023. Highly experienced interior designers, whom we refer to as Trade Buyers, are frequent, repeat purchasers on our online marketplace and accounted for 31% of our on-platform GMV in each of the years ended December 31, 2024 and 2023, respectively. Through our Trade 1st program, we offer these Trade Buyers, who comprise a subset of our buyers, additional benefits such as trade-only personalized support, exclusive trade pricing, and buyer incentives for which members do not pay any fees to participate in this program.

We are driving consumer demand for luxury design items online by providing global access to a traditionally fragmented, local, and offline market. As sellers and buyers of luxury design gain experience transacting online, we believe our combination of technology, service, brand positions and demand generation enable us to grow this market by providing sellers and buyers the tools and access they need.

We believe our proprietary technology platform enables a purchase funnel that is more robust and interactive than the conventional e-commerce experience. The discovery and transaction process in our industry is more complex than in most e-commerce categories. Specifically, transacting in unique luxury design requires the ability for sellers and buyers to exchange

messages, negotiate prices, arrange customized shipping support, and pay swiftly and securely through various payment methods. Our platform turns this complex order flow into an easy-to-use process and converts the valuable data we collect from buyers’ browsing and purchase activity into actionable insights for both sellers and buyers. Our platform is scalable, which we believe enables us to grow over time. We empower buyers to engage directly with sellers on our platform throughout all stages of a transaction. Our technology and data represent the cumulative experience of over 20 years of business activity, and we believe are extremely difficult to replicate.

Our Market Opportunity

We connect sellers and buyers in what has historically been a fragmented and highly localized global market for unique luxury design items. This market has generally operated offline, functioning mostly through independent galleries, boutiques, and auction houses, thereby restricting a seller’s potential buyer audience and limiting a buyer’s product selection. These offline operations create barriers to both new supply and new demand, limiting the market’s overall growth potential.

We created a single online marketplace that consolidates previously fragmented sellers and buyers globally. We believe our online marketplace, powered by our technology platform, has transformed almost all dimensions of the luxury design buying experience by increasing accessibility and enhancing selection and convenience.

Expanding the Luxury Goods Market

While the global luxury design market is already large, we believe that as a digital disruptor we have the potential to further expand the overall size of our market. We believe we are growing the market by: (1) increasing the number of digital global luxury design sellers by enabling them to transact on a global online marketplace that materially expands their potential customer base; and (2) growing the luxury design buyer base by introducing our online audience to unique products previously only accessible via in-person galleries, boutiques, and auction houses. We have sold items on our online marketplace ranging from less than $100 to over $1 million, demonstrating that high-end luxury design items are attainable and within reach of the expanding buyer audience we are attracting to the market.

Increasing Online Penetration

One of the most significant trends driving online penetration in the luxury goods market is an increasingly digitally native customer base. We hosted approximately 1.8 million listings as of December 31, 2024, compared to approximately 1.7 million listings as of December 31, 2023. Additionally, we had 7.0 million users as of December 31, 2024, compared to 6.3 million users as of December 31, 2023.

The 1stDibs Marketplace

Trust

Trust is at the core of the online marketplace that we have built over two decades of operating history. Trust in our online marketplace is critical to facilitating online transactions of purchases with high price points. For the years ended December 31, 2024 and 2023, approximately 3% and 5% of orders had an item value of $100,000 or more, respectively. Our seller onboarding process which includes our in-house experts evaluating the integrity of sellers’ listings inspires buyer confidence in our sellers and in the quality of the luxury design items sold on 1stDibs. Extensive fraud protection and secure payment solutions further establish the trust sellers and buyers have in our online marketplace. We believe the ability for buyers to interact and negotiate prices directly with sellers increases both on-platform conversion and buyer retention rate. Our 1stDibs Promise gives our buyers peace of mind with every purchase by providing the following features and commitments:

•a Money-Back Guarantee if a purchased item is not as described, is damaged in transit, or does not arrive, a buyer can contact us within 7 days, or longer for Trade Buyers, for a full refund.

•a community of sellers from around the world to ensure high-quality products;

•confidence at checkout with multiple secure payment options and a comprehensive fraud protection and prevention program;

•customer service support from dedicated specialists to answer questions, assist with orders, and stand ready to resolve any transaction or technical issues throughout the buying process;

•worry-free cancellations within 24 hours;

•a Price-Match Guarantee to ensure that if a buyer finds a 1stDibs seller that has the same item for a lower price elsewhere, 1stDibs will match it; and

•enablement of a seamless and transparent global end-to-end shipping, logistics and delivery experience focused on security and a high level of care.

Value Proposition to Sellers

•Demand Generation: As of December 31, 2024, we provided sellers access to a global base of approximately 7.0 million users in over 190 countries, who would otherwise largely be inaccessible in an offline market. Our Active Buyers had 81 and 86 sessions and viewed 266 and 218 product pages, on average, during the years ended December 31, 2024 and December 31, 2023, respectively. We built 1stDibs to empower and inspire confidence in our sellers by using our proprietary technology to digitize and transform their businesses. We believe that creating a digital presence and enabling access to buyers across the globe allows us to expand the addressable market for luxury sellers. Expanding a seller’s ability to share their story across various forms of media, including text, photographs, and videos, significantly increases buyer engagement and conversion. Once sellers are added to our online catalog, we help build sellers’ online presence through editorial and social placements, including our online magazine Introspective, which offers sellers additional avenues through which to advertise online.

•Digital Presence: We help sellers establish a digital presence on our online marketplace. Sellers can customize their listings on 1stDibs by uploading biographies, item descriptions, photos, videos, and content to distinguish themselves. This allows sellers to provide nuanced details about each piece, show scale and curate their inventory to feature specific items. Sellers can make changes at their discretion at any time. This information provides more context about our sellers’ listings and builds trust with our buyer community. As sellers increase sales they are potentially more able to tap into our platform benefits, such as partner managers, elevated listing visibility, and paid media coverage.

•Data Analytics: Our platform provides us with rich data throughout the entire user journey. This data allows sellers to offer more relevant products and optimize their pricing strategies, which enables them to efficiently scale their businesses. We provide sellers with a comprehensive suite of seller tools, education, and analytics, including reporting, tracking, and inside perspectives on pricing based on the historical sales of similar items. Sellers also benefit from our proprietary algorithms and targeting technologies to connect with both Consumer and Trade Buyers.

•Listing & Pricing: We empower sellers with tools useful for them to control item pricing and item visibility on our online marketplace. Sellers can leverage our proprietary classification methodologies and structured data to create listings tailored to their inventory. We have created a pricing index, “1stDibs Insider,” which provides pricing guidance to our sellers based on historical pricing trends. By providing historical pricing data for similar items that have recently sold, we believe this helps sellers price items more competitively. We have also invested in artificial intelligence and machine learning to help our sellers with pricing guidance. On our platform, sellers can set item pricing based on user type (Consumer vs. Trade) or a specific user (Private Listing). We also provide sellers purchase format flexibility beyond the standard list price model. Sellers can choose to list items without a price using the “Price Upon Request” purchasing format. Furthermore, sellers can review, accept, or counter-offer negotiation requests, or create “Private Offers” for prospective buyers and “Automated Private Offers” (preset and triggered by buyer behavior).

•Operational Efficiency: Our sellers can efficiently scale their businesses without the friction associated with in-person sales and multiple third-party platforms. The ability to offer a convenient, seamless transaction experience, including on-platform communications and a wide range of payment solutions, such as credit card, PayPal, Apple Pay, Automated Clearing House (“ACH”), and wire transfer further drives buyer conversion. We maximize Search Engine Optimization (“SEO”) to help buyers find items and connect with our sellers, allowing them to purchase products tailored to their tastes and preferences with ease. We have assembled a robust network of logistics providers to help sellers fulfill orders at a lower cost, giving them an advantage relative to conventional offline sales and allowing them to focus more time on what they do best: curating and selling unique luxury design items.

Value Proposition to Buyers

We provide buyers with tools to communicate directly with sellers, receive quick responses, negotiate prices, and access multiple payment methods for a convenient checkout experience. We curate our buyers’ experience to target their specific tastes and preferences and provide them with design inspiration through our expertly merchandised collections and our online editorial publications. Our platform calculates a “salability” score for items using machine learning and gives items with a higher likelihood of selling increased priority in buyers’ search and browse sort order. Additionally, our platform offers pricing insights to show buyers historical pricing data for similar items that have recently sold which can increase buyer confidence and help buyers with decision-making and in negotiations. Our customized Private Client and Trade Service teams provide high-touch human support for Consumer and Trade Buyers. Our buyer services include:

•Largest Selection of Unique Luxury Design Items: We offer one of the largest online selections of luxury design items from leading sellers and makers of vintage, antique, and contemporary furniture, home décor, jewelry, watches, art, and fashion. We believe our growing collection of approximately 1.8 million luxury design items is unmatched and makes us the premier destination for design lovers and enthusiasts. Luxury design tends to retain value over time as a result of their scarcity and durability. We aggregate supply from a large number of globally distributed sellers, offering buyers an online destination to access a variety of luxury products across the globe. As of December 31, 2024 and December 31, 2023, we had approximately 45% and 44% of our listings located outside the United States, respectively. The percentage of our unique sellers based outside of the United States was 53% and 55% as of December 31, 2024 and December 31, 2023, respectively.

•Buyer-Seller Communication: Given the unique inventory available on our online marketplace and the relatively high price points, buyers are likely to have questions regarding origin and item attributes. We have developed tools to facilitate communication between sellers and buyers and have added incentives for sellers to respond quickly. Negotiation is a common purchase format in our verticals; Buyers can negotiate via the “Make Offer” experience, and also receive a personalized “Private Offer” after initiating a conversation with a seller or “favoriting” an item.

•Mobile: During the year ended December 31, 2024, the majority of user sessions came to our online marketplace via a mobile device, either by browsing our mobile site or by using our highly rated mobile app. The bulk of our users are browsing via our mobile site. Our mobile app users take advantage of app-specific features, personalized notifications, and the ability to “see” items in their homes via our augmented reality feature.

•Personalization: We collect rich data around our users’ preferences, site engagement, item and seller attributes, buyers’ browsing patterns and purchase behaviors. As a result, we are able to curate our buyers’ experience to target their specific tastes and preferences. We use this data to personalize our marketing efforts and listing suggestions. These include alerts when new items from followed creators are listed, item recommendations, discovery feeds, and highly contextual emails. This personalization improves user engagement. We provide high-touch human support for Consumer and Trade Buyers through our customized Private Client and Trade teams, which further enhances the buying process.

•Curated Assortment: We are a highly sought after destination for unique, high-quality luxury design items. We provide buyers with design inspiration through our expertly merchandised collections and our online editorial publication Introspective.

•Quality of Experience: Unlike conventional offline alternatives, we offer our buyers convenient 24/7 access to approximately 1.8 million listings. Multiple possible payment methods offer our buyers a convenient checkout experience compared to traditional offline retail channels by removing complexity and introducing transparency to the purchasing process. We allow buyers to transact securely from their homes, bypassing the complicated and time-intensive process, and often opaque pricing associated with traditional offline channels. Our valuable buyer base also appreciates the privacy and anonymity associated with purchasing products online through our marketplace. Our Price-Match Guarantee further increases purchasing confidence, as buyers are assured they will always transact at the lowest price. In addition, we provide additional benefits to Trade Buyers, including trade exclusive pricing, buyer incentives, priority support, sourcing expertise, and enhanced buyer protection, among others through our Trade 1st program. Our client service associates help ensure the satisfaction of sellers and buyers by addressing and assisting in the resolution of questions relating to orders, deliveries, returns, and disputes. For certain individual Consumers or Trade Buyers, respectively, we provide support at the individual level through our Private Client and Trade Services to provide a seamless buying process.

Our Growth Strategies

Expand Our Buyer Base

We are focused on continuing to grow our buyer base and believe we are still in the early stages of introducing a unique and growing supply of luxury design items to a much broader audience. Of our 7.0 million users as of December 31, 2024, we estimate based on the available information provided by our users that approximately 64% are U.S.-based and 36% are international, which represents approximately 1% penetration of the U.S. population and less than 1% of the international population. As of December 31, 2023, we estimated that approximately 66% of our 6.3 million users were U.S.-based and 34% were international. Approximately 20% of our buyers are located internationally as of both December 31, 2024 and 2023.

To date, we have primarily grown our current buyer base organically through word-of-mouth, mentions in the press, and earned media, as well as paid media, promotions, and third party partnerships. We believe we can significantly increase our buyer base by utilizing targeted, data-driven marketing efforts that generate meaningful returns. We believe we can continue to

expand our buyer audience across a wide swath of buyer demographics including income, geography, and age, as well as level of design experience and design preference.

Grow Our Marketplace Supply

We intend to further increase the supply on our online marketplace by offering a captivating value proposition and enhanced item listing tools, adding new inventory from existing sellers, and growing the range of sellers from whom we source. We continue to enhance our value proposition for sellers by providing broad and growing access to a global base of design-minded buyers and a platform with a comprehensive suite of tools that help our sellers successfully transact and scale their business. This value proposition drives sellers to our online marketplace, deepens the breadth of our inventory, and helps attract new buyers.

We may also choose to expand our network of sellers inorganically, either through acquisitions of, or partnerships with, companies or design brands.

Investment in Technology and Innovation

We have made, and will continue to make, strategic investments in our platform to drive seller success through new tools, convert users to buyers, grow our long-term revenue and operating results, drive technological innovation, and enhance the overall experience of our online marketplace. As we continue to scale, we plan to strategically invest in innovation, including continued investment in machine learning and artificial intelligence, to address the needs of our sellers and buyers and drive efficiencies in our business, localize our platform, and may enter new verticals and geographies. Overall, investments in our platform are focused on maximizing traffic, increasing conversion rate, and improving the overall efficiency of our operations.

Marketing

We acquire new buyers and drive traffic to our online marketplace through a mix of direct response marketing channels, with an emphasis on digital and a focus is on efficient growth. We derive a relatively low percentage of our traffic and orders from paid media. During the year ended December 31, 2024, we estimate that approximately 69% of new user sessions came from non-paid channels, including organic search, direct web, direct app, organic social, email, and referral compared to 76% during the year ended December 31, 2023.

We utilize user data and rigorous A/B testing to improve the user experience, and continuously optimize the performance of our marketing campaigns and channels. We use highly targeted promotional incentives, where appropriate, to profitably acquire and retain buyers. We focus on engaging and retaining our users with personalized experiences and elevated storytelling. We understand user preferences from their discovery and purchase history, and use that data to recommend products that are most likely to drive engagement, conversion, and repeat purchasing. We offer Private Client services to our most engaged consumers; and cultivate interior designer engagement and retention through the Trade 1st program. We communicate with our buyers primarily through email, site, text, mobile push notifications, print catalogs, and organic social.

We acquire new sellers through a combination of inbound applicants who primarily find us by word of mouth from other sellers, as well as focused lead sourcing. We review all applications from these efforts, tier them according to desirability based on their inventory quality and “salability” onsite, and then invite the approved sellers to join our online marketplace.

Pursue New Product Verticals and Diversification Opportunities

We have demonstrated our ability to successfully grow and diversify beyond our original offering of vintage furniture, as exemplified by our proven track record of expanding both across verticals, such as art, jewelry, and fashion, and within verticals, such as the expansion from vintage and antique furniture to include new and custom furniture. Antique and vintage furniture comprised less than 50% of our on-platform GMV in the years ended December 31, 2024 and 2023, respectively. We expect antique and vintage furniture to account for less than 50% of on-platform GMV for the foreseeable future. Adding verticals has several benefits, including increasing our addressable market, the number of sellers and buyers, purchase frequency, and offering our buyers a wider supply of inventory while strengthening our brand as a preeminent online destination for luxury design items. We intend to continue to evaluate such diversification opportunities as part of our overall growth strategy. Our platform infrastructure is designed to scale with growth and diversification in mind.

Expand Internationally

During the year ended December 31, 2024, the vast majority of our buyers were located in the United States and other English-speaking countries. As of December 31, 2024, 45% of the supply on our online marketplace comes from outside the United States, while only 20% of buyers are located internationally. We believe that this presents a large international expansion opportunity. Our website traffic also indicates strong international presence and opportunities for conversion, with approximately 44% of current traffic coming from outside the United States. We had 53% and 55% of unique sellers and 45% and 44% of the supply on our online marketplace come from outside the United States in the years ended December 31, 2024,

and 2023, respectively. On-platform GMV from buyers in non-U.S. markets constituted 18% and 17% in the years ended December 31, 2024, and 2023, respectively. We believe there is an opportunity to grow our GMV from non-U.S. markets, and may also expand internationally through acquisitions.

Human Capital Resources

As of December 31, 2024, we had 284 full-time employees, including 104 in technology development, 78 in sales and marketing, 38 in general and administrative, and 64 in operations. The 20% increase in full-time employees from December 31, 2023 is primarily due to an acquisition of a Lithuanian technology support company that is now a wholly owned subsidiary of the Company.

Our human capital resources objective is to ensure that we have the best possible team to reach our business goals, and that the team has a positive employee experience. We do this through striving to attract and hire the best talent and developing our team in ways that contribute to their personal and business growth. We regularly receive input from our team members through employee surveys, feedback interviews, and events to gauge employee engagement and identify areas of focus.

Our Technology and Data

Technology powers all aspects of our business. Our proprietary services-based architecture is the foundation of our platform. It is designed to connect sellers and buyers worldwide, enabling online transactions of unique products by removing purchase friction. We leverage appropriate technologies to ensure security, performance, and scalability. Key features of our technology platform include:

•Services-based Architecture: Allows us to scale individual parts of the platform independently from others, increasing engineering efficiency. It also facilitates using different programming languages appropriate for specific tasks, including python for machine learning, java for big data jobs, and node for front end integrations.

•Proprietary Database: We created an extensive digital catalog in luxury design with associated metadata that is used to simplify the buyer experience in an ordinarily complex purchase process. This database includes taxonomies, structured metadata, an expansive catalog of luxury brands and designers, and an extensive library of luxury design items, product attributes, and pricing data. Our highly sophisticated, purpose-built technology stack facilitates complex, multi-step online transactions and is extremely difficult to replicate. Technology powers all aspects of our business, including our complex single-SKU and multi-SKU order management system.

•Big Data: We leverage browsing history on our platform, followed searches, “favorited” items, and previous purchases to generate personalized emails and on-site recommendations. This data provides us the ability to predict the relative likelihood of an item selling, as compared with other items, based upon price point and the quality of the listing, images, and shipping quotes. We leverage this data, including user behaviors, sales trends, and seller behaviors, to improve the effectiveness of our buyer targeting and conversion efforts, and increase supply growth from existing and prospective sellers.

•Scalable Page Creation: We utilize unstructured on-platform search query data to create new indexable pages automatically to increase our long-tail organic search traffic and enable broader Search Engine Optimization and Search Engine Marketing (“SEM”) coverage.

•System Security and Business Continuity: Our infrastructure has been designed to adhere to industry best practices for secure storage and management of all sensitive data, including encryption (for data at rest as well as in transit), access logging, and internal change controls. Physical and logical access controls are in place, and personally identifiable information is obfuscated. Utilize third-party servers across multiple availability zones with data securely backed up in real time across multiple regions.

As our online marketplace grows, our data becomes increasingly valuable. This data advantage allows us to develop business processes to optimize our operations, including marketplace supply, merchandising, authentication, pricing, marketing, and servicing. We collect and share data from across the platform to improve seller tactics and help them make informed decisions about sourcing, pricing, and selling products on our online marketplace. We use internal and external data to target, acquire, and retain qualified buyers through performance-based, data-driven marketing campaigns.

Data Security and Protection

We are committed to the security of the sellers and buyers who transact on our marketplace. We collect and store certain personally identifiable information provided by our sellers and buyers and other third parties with whom we transact, such as names, email addresses, and the details of transactions. We do not directly collect, transmit, and store personal financial information such as credit card data and other payment information and rely on third-party payment processors who provide these services on our behalf. The collection, transmission, and storage of such information is subject to stringent legal and regulatory obligations. Some of our third-party service providers, such as identity verification and payment processing

providers, also regularly have access to seller and buyer data. We undertake administrative and technical measures to protect our systems and the consumer data those systems process and store. We have developed policies and procedures designed to manage data security risks, including employment of technical security defenses and continual monitoring of servers and systems. Further, as part of our efforts to protect sensitive information, we rely on a variety of security measures, including encryption and authentication technology licensed from third parties. We also use third parties to assist in our security practices and prevent and detect fraud. We intend to continue to invest in efforts associated with the detection and prevention of security breaches and any security-related incidents.

Segment and Geographic Information

We have one operating and reportable segment. See Note 2 “Summary of Significant Accounting Policies” to our consolidated financial statements for further discussion of our operating and reportable segment.

Regulatory

Our business is subject to a growing number of local, national, and international laws and regulations, which are applicable to any company conducting business on the internet and in the resale market. These laws are often complex, unclear, sometimes contradict other laws, and are frequently changing. Compliance is costly and can require changes to our business practices and significant amounts of management time and focus.

Laws may be interpreted and enforced in different ways in various locations around the world, posing a significant challenge to our global business. These include laws governing areas such as personal privacy and data security, consumer protection, payment processing, sales and other taxes, and unfair and deceptive trade practices, among other areas. Related laws may govern the manner in which we store or transfer sensitive information, or impose obligations on us in the event of a security breach or inadvertent disclosure of such information. International jurisdictions impose different, and sometimes more stringent, consumer and privacy protections.

We list luxury design items from numerous sellers located throughout the United States and from over 75 countries. As such, we need to comply with various laws and regulations associated with doing business outside of the United States, including regarding the handling of antique and vintage items and licensing requirements of antique and vintage dealers, export control laws, economic and trade sanctions, anti-money laundering laws, and anti-corruption laws. Further, various countries regulate the import of certain technology and have enacted or could enact laws that limit our ability to provide sellers and buyers access to our platform or could limit our sellers’ and buyers’ ability to access or use our services in those countries.

Although we take precautions to prevent violations of these laws, our exposure for violating these laws increases as our international presence expands and as we increase sales and operations in foreign jurisdictions. See Part I, Item IA, “Risk Factors—Regulatory, Compliance, and Legal Risks.”

New legislation or regulation or changes thereof due to federal elections, the application of laws from jurisdictions whose laws do not currently apply to our business, or the application of existing laws and regulations to the internet and e-commerce generally could result in significant additional compliance costs and responsibilities for our business.

Competition

We compete with a broad range of sellers of new and pre-owned luxury design items, including traditional brick-and-mortar entities, such as department stores, branded luxury goods stores, and specialty retailers, and entities providing access to more unique luxury goods, such as galleries, boutiques, and auction houses. We also compete with the online offerings of these traditional retail entities, as well as online marketplaces that may offer the same or similar goods and services that we offer.

We believe that we compete effectively based on the volume, quality, and assortment of unique luxury design items available on our online marketplace, our brand awareness and history built on trust and authenticity, the experience and value proposition we offer to sellers and buyers, and the global scale of our online marketplace, including the effectiveness of our mobile app.

Intellectual Property

We rely on a combination of intellectual property rights, contractual protections, and other practices to protect our brand, proprietary information, technologies and processes. We primarily rely on copyright, trademark, trade secrets, confidentiality agreements, and domain name registration in the United States and abroad to protect our brand, proprietary information, proprietary technologies and proprietary processes, including the algorithms we use throughout our business. Our principal trademark assets include the registered trademark “1stDibs” and our logos and taglines. Our trademarks are valuable assets that support our brand and consumers’ perception of our services and merchandise. We also hold the rights to the “1stDibs.com” Internet domain name and various related domain names, which are subject to Internet regulatory bodies and trademark and other related laws of each applicable jurisdiction. Although we do not currently have any issued patents, we may pursue patent protection for aspects of our technology in the future. We seek to protect our proprietary information, in part, by entering into

confidentiality and proprietary rights agreements with our employees and independent contractors. Our employees are also subject to invention assignment agreements. See “Risk Factors—Risks Relating to Intellectual Property.”

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including our audited consolidated financial statements and related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before investing in our common stock. If any of the following risks are realized, in whole or in part, our business, financial condition, results of operations, and prospects could be materially and adversely affected. In that event, the price of our common stock could decline, and you could lose part or all of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business, financial condition, results of operations, and prospects.

Risks Related to Our Business and Industry

We have a history of operating losses, and we may not achieve or maintain profitability in the future, which in turn could negatively impact our financial condition and our stock price.

We incurred net losses of $18.6 million, $22.7 million, and $22.5 million during the fiscal years ended December 31, 2024, 2023, and 2022, respectively. We had an accumulated deficit of $332.4 million as of December 31, 2024. We expect to incur significant losses in the future. We will need to generate and sustain increased revenue levels or reduce operating costs materially in future periods to achieve profitability, and even if we achieve profitability, we may not be able to maintain or increase our level of profitability. Our operating expenses may increase substantially in the foreseeable future to the extent necessary that we may hire additional employees, invest in expanding our seller and buyer base and deepening our existing seller and buyer relationships, expand across and within product verticals, increase our marketing efforts and brand awareness, and invest in expanding our international operations. Our efforts to grow our business may be more costly than we expect, and we may not be able to increase our revenue enough to offset our higher operating expenses. If we were to reduce our expenses, it could negatively impact our growth and growth strategy. As a result, we can provide no assurance as to whether or when we will achieve profitability. If we are not able to achieve and maintain profitability, the value of our company and our common stock could decline significantly, and you could lose some or all of your investment.

Our net revenue and results of operations fluctuate within each quarter and from quarter to quarter, causing our stock price to fluctuate and making our financial results difficult to predict.

Our quarterly and annual net revenue and results of operations, as well as our key metrics, have historically fluctuated from period to period, with net revenue of $88.3 million, $84.7 million, and $96.8 million during the fiscal years ended December 31, 2024, 2023, and 2022, respectively. Our future net revenue or results of operations may vary significantly from quarter to quarter, due to a variety of factors, many of which are beyond our control. These fluctuations could cause our stock price to change significantly or experience declines. You should not rely on period-to-period comparisons of our net revenue or results of operations as an indication of our future performance. Factors that may cause fluctuations in our quarterly results of operations, many of which are beyond our control, include, but are not limited to, the following:

•fluctuations in net revenue generated from sales of luxury design items through our online marketplace;

•our success in attracting and retaining sellers and buyers to and on our online marketplace, and our ability to do so in a cost-efficient manner;

•our ability to attract users to our website and convert users to Active Buyers on our online marketplace;

•Active Buyers with multiple unique email accounts that are undetected and in violation of our terms of service as we could be overestimating the number of Active Buyers;

•the amount and timing of our operating expenses;

•our ability to continue to source and provide available luxury design items on our online marketplace;

•the timing and success of new services, features, and offerings we introduce through our e-commerce platform;

•our ability to compete successfully;

•our ability to increase brand awareness of our company and our online marketplace;

•our ability to manage our existing business and future growth;

•our ability to effectively scale our operations while maintaining high-quality service and seller and buyer satisfaction;

•the amount, timing, and results of our investments to maintain and improve our technology infrastructure and platform, and our ability to do so in a cost-effective manner;

•our ability to increase and manage the growth of our international operations, including our international seller and buyer base, and our ability to manage the risks associated therewith;

•changes in our key metrics or the methods used to calculate our key metrics;

•more challenging comparisons to prior periods as our net revenue grows;

•a decrease in the growth of our overall market or market saturation;

•our failure to capitalize on growth opportunities;

•seasonality, including seasonal buying patterns, which vary from quarter to quarter or year to year;

•changes in laws, regulations, governmental policies, or accounting principles that impact our business, business partners or customers;

•disruptions or defects in our e-commerce platform, such as service interruptions or privacy or data security breaches;

•changes in the terms of our seller agreements;

•our ability to hire and retain talented employees and professional contractors at all levels of our business;

•the changing consumer behaviors and factors that affect consumer behaviors and spending, such as economic conditions, inflationary pressures, interest rates, discretionary spending patterns, employment levels, instability in the housing market, geopolitical crises, or significant economic or social disruption; and

•economic and market conditions, particularly those affecting the luxury design items industry, such as fluctuations in inflation and interest rates or supply chain or global shipping disruptions.

We also expect our operating expenses to increase in future periods, and if our revenue growth does not increase to offset these anticipated increases in our operating expenses, our business, financial condition, and results of operations will be harmed, and we may not be able to achieve or maintain profitability. Further, these and other factors may cause our net revenue and results of operations to fall below our expectations or the expectations of market analysts and investors in future periods, which could cause the market price of our common stock to decline substantially. Any decline in the market price of our common stock would cause the value of your investment to decline.

Our business is affected by seasonality and, if we experience lower than expected net revenue during an anticipated season, our results of operations and financial condition for that year may be impacted, which could substantially harm our business, results of operations, and financial condition.

Our business is subject to seasonal fluctuations, and, as a result, we make certain assumptions when planning our expenses based on our expected revenue based in part on historical results. Because our operating expenses are relatively fixed in the short term, any failure to achieve our revenue expectations would have a direct, adverse effect on our results of operations. If actual results differ from our estimates, the trading price of our common stock may decline. We have generally recognized higher net revenue in the fourth quarter. In anticipation of increased activity during the fourth quarter, we may incur significant additional expenses, including additional marketing and staffing in our support operations. If we experience lower than expected net revenue during any fourth quarter, it may have a disproportionate impact on our results of operations and financial condition for that year. Any factors that harm our fourth quarter results of operations, including disruptions in our sellers’ willingness to list items or unfavorable economic conditions could have a disproportionate effect on our results of operations for our entire fiscal year. In the future, our seasonal sales patterns may become more pronounced, may strain our personnel, and may cause a shortfall in net revenue related to expenses in a given period, which could substantially harm our business, results of operations, and financial condition.

Our ability to grow our business and market share depend on our ability to attract and maintain an active community of sellers and buyers and to ensure a sufficient volume of listings on our online marketplace.

Our business growth and market success depend on our ability to cost-effectively attract, retain, and grow relationships with active sellers and buyers, and in turn, the volume of luxury design items listed and sold through our online marketplace. We cannot be certain that our efforts will attract more sellers, induce sellers to list and sell more luxury design items on our online marketplace, or yield a sufficient return on investment. Moreover, sellers may be dissatisfied with their experience and choose not to continue to list with us or list items as frequently, or they may stop referring others to us. Similarly, we cannot be certain that our efforts will attract more buyers, induce more buyers to purchase on our online marketplace, or yield a sufficient

return on investment. If existing buyers have a negative experience or if the interest in buying luxury design items declines, they may make fewer purchases or they may stop referring others to us.

To expand our buyer base, we must appeal to and attract buyers of luxury design items and convert users to Active Buyers on our online marketplace. New buyers may not purchase through our online marketplace as frequently or spend as much with us as existing buyers. As a result, the revenue generated from new buyer transactions may not be as high as the revenue generated from transactions with our existing buyers. Our historical performance for Active Buyers may not be indicative of future performance in new Active Buyers. Failure to attract new buyers and to maintain relationships with existing buyers, or to convert users to Active Buyers on our online marketplace, would harm our results of operations and our ability to attract and retain sellers.

Even if we are able to attract new sellers and buyers to replace any that we lose, they may not maintain the same level of activity and generate the same level of revenue. If we are unable to retain existing, or attract new, sellers and buyers, our growth prospects would be harmed, which could substantially harm our business, results of operations, and financial condition.

Further, our historical seller marketplace services revenue may not be indicative of future revenue. We are highly selective in the sellers we allow onto our online marketplace and sellers undergo an evaluation by our in-house experts to vet the integrity of their listings before they are allowed to join our online marketplace. As a result, we may have difficulty identifying sellers who meet our standards for providing luxury design items and our customer service requirements. If we fail to attract new sellers or drive continued or increased listings, our ability to grow our business and our results of operations would suffer. See “Risk Factors—Risks Related to Our Business and Industry—We rely, in part, on sellers to provide a positive experience to buyers.”

We may expand our business through acquisitions of other businesses, products, or technologies, which have required, could continue to require, and may require significant management attention, could disrupt our business, dilute stockholder value, adversely affect our operating results, and/or prove to be unsuccessful.

We have acquired a number of other businesses in the past, and may acquire additional businesses, products, or technologies in the future. For example, in May 2019, we acquired Design Manager, a project management and accounting software company for interior designers. Also, in June 2022, we sold 100% of our equity interest in Design Manager. Acquisitions may divert management’s time and focus from operating our business. Acquisitions also may require us to spend a substantial portion of our available cash, incur debt or other liabilities, amortize expenses related to intangible assets, or incur write-offs of goodwill or other assets. In connection with these types of transactions, we may be required to issue equity securities, which could cause dilution to our stockholders. In addition, integrating an acquired business or technology is risky. Completed and future acquisitions may result in unforeseen operational difficulties and expenditures associated with:

•incorporating and integrating new businesses, technologies, products, personnel, or operations of any company we may acquire, particularly if key personnel of the acquired company decide not to work for us;

•consolidating operational and administrative functions;

•coordinating outreach to our community;

•disruption to our ongoing business and distraction of our management;

•delay or reduction of transactions on our marketplace or in the business of the company we acquired due to uncertainty about continuity and effectiveness of service from either company;

•entry into geographic or business markets in which we have little or no prior experience or where competitors have stronger market positions;

•effectively managing an increased number of employees in diverse locations;

•if we use cash to pay for acquisitions, limiting other potential uses for our cash;

•incurring debt to fund such acquisitions, which may subject us to material restrictions on our ability to conduct our business;

•issuing our equity securities;

•incurring impairment charges related to potential write-downs of acquired assets or goodwill;

•maintaining morale and culture and retaining and integrating key employees;

•maintaining or developing controls, procedures, and policies (including effective internal control over financial reporting and disclosure controls and procedures); and

•assuming liabilities related to the activities of the acquired business before the acquisition, including liabilities for violations of laws and regulations, commercial disputes, taxes, and other matters.

In addition, an acquisition may negatively affect our results of operations and financial condition because it may require us to incur charges or assume substantial debt or other liabilities, may cause adverse tax consequences or unfavorable accounting treatment, may expose us to claims and disputes by third parties, including intellectual property claims and disputes, or may not generate sufficient financial return to offset additional costs and expenses related to the acquisition.

Moreover, we may not benefit from our acquisitions as we expect, or in the time frame we expect, or we may elect to divest ourselves of prior acquisitions, such as our sale of Design Manager in June 2022. We also may issue additional equity securities in connection with an acquisition, which could cause dilution to our stockholders. Finally, acquisitions could be viewed negatively by analysts and investors or by our sellers and buyers. We may not succeed in addressing these or other risks, which could harm our business and results of operations.

Our ability to establish the authenticity of items listed and sold through our online marketplace is essential to maintaining our business, brand, and reputation. Failure to do so may adversely affect customer trust and pose risks to our operations and standing in the market.

We have built a trusted online marketplace with a reputation for authentic luxury design items as a result of our evaluations by in-house experts to vet the integrity of sellers’ listings. Our success depends on our ability to accurately and cost-effectively determine whether an item offered for listing, such as a piece of jewelry or work of art, is an authentic product. We seek to reassure buyers that the items they are purchasing meet our marketplace standards. Our sellers undergo a comprehensive evaluation by our vetting specialists to ensure the quality of their inventory. Our vetting specialists come from many of the leading auction and retail houses, brands, and industry recognized art and design businesses. We also seek to proactively resolve issues through communication and follow-up. Factors that could undermine our ability to maintain trust in our online marketplace include:

•complaints or negative publicity about us or our online marketplace or platform, even if factually incorrect or based on isolated incidents;

•changes to our policies to which our seller and buyer network react negatively or that are not clearly articulated;

•our failure to enforce our policies fairly and transparently; and

•our failure to respond to feedback from our seller and buyer network.

From time to time, counterfeit goods have been and may be listed on our online marketplace. While we have invested heavily in our seller vetting process as described above, we cannot accurately authenticate every item that is listed with us. As the sophistication of counterfeiters increases, it may be increasingly difficult to identify counterfeit products. In many cases, we refund the cost of a product to a buyer if we determine that the item is not authentic. The sale of any counterfeit goods may damage our reputation as a trusted online marketplace for authenticated, luxury design items, which may impact our ability to attract and maintain repeat sellers and buyers. Additionally, we may be subject to allegations that an antique, vintage, or other luxury design item we listed and sold through our online marketplace is not authentic. Such controversy could negatively impact our reputation and brand and harm our business and results of operations. If we are unable to maintain the quality and authenticity of the items listed on our online marketplace, our ability to retain and attract sellers and buyers could be impaired and our reputation, brand, and business could suffer.

Items listed on our online marketplace may be subject to claims of being counterfeit, infringing, hazardous, illegal, or otherwise subject to regulations or cultural patrimony considerations. Addressing such claims can result in operational, legal, and reputational challenges.

Although we do not create or take possession of the items listed on our online marketplace, we have from time to time received, and may in the future receive, communications alleging that items listed on our online marketplace infringe third-party copyrights, trademarks, patents, or other intellectual property rights, or that items we list from our sellers contain materials such as fur, python, ivory, and other exotic animal product components, that are subject to regulation or cultural patrimony considerations, or that may be deemed hazardous or illegal. We have complaint and take-down procedures in place to address these communications and listings, and we believe such procedures are important to promote confidence in our online marketplace. We follow these procedures to review complaints and relevant facts to determine the appropriate action to take, which may include removal of the item from our online marketplace and, in certain cases, removing the sellers who repeatedly violate our policies.

Our procedures may not effectively reduce or eliminate our liability. In particular, we may be subject to civil or criminal liability for activities carried out by sellers on our online marketplace, especially outside the United States where we may be less protected under local laws than we are in the United States. Under current U.S. copyright law and the Communications

Decency Act, we may benefit from statutory safe harbor provisions that protect us from liability for content posted by our sellers and buyers. However, trademark and patent laws do not include similar statutory provisions and liability for these forms of intellectual property is often determined by court decisions. These safe harbors and court rulings may change unfavorably. In that event, we may be held secondarily liable for the intellectual property infringement of sellers.

Regardless of the validity of any claims made against us, we may incur significant costs and efforts to defend against or settle them. If a governmental authority determines that we have aided and abetted the infringement of third-party intellectual property rights or the sale of counterfeit goods or if legal changes result in us potentially being liable for actions by sellers on our online marketplace, we could face regulatory, civil, or criminal penalties. Successful claims by third-party rights owners could require us to pay substantial damages or refrain from permitting any further listing of the relevant items. These types of claims could force us to modify our business practices, which could lower our revenue, increase our costs, or make our platform less user-friendly. Moreover, public perception that counterfeit or other unauthorized items are common on our online marketplace, even if factually incorrect, could result in negative publicity and damage to our reputation.

Liability for fraudulent or unlawful activities by sellers, including the listing of stolen items on our online marketplace, poses risks to our business and reputation.

Despite our vetting process and contractual requirements prohibiting the listing of stolen or otherwise illegal products, from time to time, the listing of stolen goods on our online marketplace may occur. Government regulators and law enforcement officials may allege that our services violate, or aid and abet violations of certain laws, including laws restricting or prohibiting the transferability and, by extension, the resale, of stolen goods. We may be required to spend substantial resources to take additional protective measures which could negatively impact our operations. Any costs incurred as a result of potential liability relating to the alleged or actual sale of stolen goods could harm our business. In addition, negative publicity relating to the actual or perceived listing or sale of stolen goods using our services could damage our reputation and discourage our sellers and buyers from using our services. We could face liability for such unlawful activities. Despite measures taken by us to detect stolen goods, to cooperate fully with law enforcement, and to respond to inquiries regarding potentially stolen goods, any resulting claims or liabilities could harm our business.

We rely, in part, on sellers to provide a positive experience to buyers, which includes limited disruptions in service by sellers.

We have, on occasion, received reports from buyers that they have not received the items that they purchased, that the items received were not as represented by the seller, or that we or a seller has not been responsive to their questions. Negative publicity and sentiment generated as a result of complaints could reduce our ability to attract or retain buyers or damage our reputation. A perception that our levels of responsiveness and seller and buyer support are inadequate could have similar results.

Further, any disruption in the operations of a substantial number of sellers, such as interruptions in delivery services or disruption due to public health crises, natural disasters, inclement weather, or political unrest, could also result in negative experiences for a substantial number of buyers. If buyers do not have a positive experience transacting business on our online marketplace for any reason, or if we or our sellers fail to provide a high level of customer support and responsiveness, it could harm our reputation and our business.

Shipping and logistics are critical to our business, and delays, failures, or issues with the condition of items delivered through our online marketplace harm our business and reputation.

We and our sellers work with a number of third-party services to deliver their items to buyers, including DHL, FedEx, UPS, and the United States Postal Service. Anything that prevents timely delivery of goods to buyers could harm sellers and could negatively affect our reputation. Delays or interruptions may be caused by events that are beyond the control of the delivery services, such as inclement weather, natural disasters, transportation disruptions, delays in customs inspections, terrorism, war, geopolitical tension, public health crises, or labor unrest. For example, a third-party strike may result in increased shipping costs and buyer accommodations and may cause orders to be lost or delivered late, which could result in canceled customer orders, reduced GMV and net revenue, and negatively impact net loss. It is possible that a potential third-party strike could also result in increased shipping costs and buyer accommodations. These potential impacts may have a material adverse effect on our business, financial condition, including on our financial statements of operations and cash flow, operating results, and liquidity. The delivery services could also be affected by industry consolidation, insolvency, or government shutdowns. Although we have agreements with certain delivery services that enable us to provide pre-paid shipping labels as a convenience to sellers, our agreements do not require these providers to offer delivery services to sellers. Further, our competitors could obtain preferential rates or shipping services, causing sellers to pay higher shipping costs or find alternative delivery services. If the items sold through our online marketplace are not delivered in proper condition, on a timely basis or at shipping rates that buyers are willing to pay, our reputation and our business could be adversely affected.

If we do not compete effectively, our results of operations and market position could suffer.

The market for luxury design items is highly competitive. We compete with a broad range of vendors of new and pre-owned luxury design items, including traditional brick-and-mortar entities, such as department stores, branded luxury goods stores, and specialty retailers, and entities providing access to more unique luxury goods, such as galleries, boutiques, independent retail stores, and auction houses. We also compete with the online offerings of these traditional retail competitors, resale players focused on niche or single categories, as well as technology-enabled online marketplaces that may offer the same or similar goods and services that we offer. We believe our ability to compete depends on many factors within and beyond our control, including:

•engaging and enhancing our relationships with existing sellers and buyers and attracting new sellers and buyers;

•maintaining favorable brand recognition and effectively delivering our online marketplace to sellers and buyers;

•identifying and delivering authentic luxury design items;

•the amount, diversity, and quality of luxury design items that we or our competitors offer;

•our ability to expand the verticals for luxury design items listed on our online marketplace;

•the price at which listed, authenticated luxury design items through our online marketplace are offered;

•the speed and cost at which we can authenticate and make available listed luxury design items; and

•the ease with which our sellers can list and sell, and our buyers can purchase and return, luxury design items sold and purchased on our online marketplace.

Failure to adequately meet these demands may cause us to lose potential sellers and buyers which could harm our business.

Many of our competitors have longer operating histories, larger fulfillment infrastructures, greater brand recognition and technical capabilities, larger databases, greater financial, marketing, institutional and other resources and larger seller and buyer bases than we do. As the market evolves, competitors may emerge. Some of our competitors may have greater resources than we do, which may allow them to derive greater revenue and profits from their existing buyer bases, attract sellers at lower costs, or respond more quickly than we can to new or emerging technologies and changes in consumer shopping behavior. These competitors may engage in more extensive technology development efforts, enter the business of online listing of luxury design items, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build larger seller or buyer bases or generate revenue from their existing seller and buyer bases more effectively than we do. If we fail to compete effectively, our business, results of operations, and market share may suffer.

Our net revenue could be negatively impacted as a result of greater than expected product returns.

We allow buyers to return certain purchases made through our online marketplace under the applicable seller’s return policy. We record a reserve for returns against proceeds to us from the sale of items on our online marketplace in calculating net revenue. We estimate this reserve based on historical return trends. The introduction of new products in the retail market, changes in seller return policies, changes in laws, legislation, or regulations governing returns, changes in consumer confidence, or other competitive and general economic conditions may cause actual returns to exceed our reserve for returns. Any significant increase in returns that exceeds our reserves could adversely affect our net revenue and results of operations.

Insufficient allowance for transaction losses could negatively impact our financial results.

We maintain an allowance for transaction losses, which consists primarily of losses resulting from our buyer protection program, including damages to products caused by shipping and transit, items that were not received or not as represented by the seller, and reimbursements to buyers at our discretion if they are dissatisfied with their experience. The provision for transaction losses also includes bad debt expense associated with our accounts receivable balance. Transaction loss expense associated with our buyer protection program accounted for approximately 70%, 87%, and 85%, of the provision for transaction losses in the years ended December 31, 2024, 2023, and 2022, respectively, with discretionary buyer reimbursements, which are part of the buyer protection program, constituting a small portion thereof. However, our historical experience may not be indicative of future trends and transaction loss expense associated with our buyer protection program, including buyer reimbursements, or bad debt expense may increase or fluctuate from period to period. Further, our provision for transaction losses may fluctuate depending on many factors, including changes to our buyer protection programs and the impact of regulatory changes, and we may see the provision for transaction losses increase proportionally with our on-platform GMV and net revenue. If our allowance for transaction losses is insufficient, it could adversely affect our results of operations.

Our business and results of operations are sensitive to changes in or uncertainty about economic conditions in the U.S. and international markets that impact consumer spending, including consumer discretionary spending.

Our business and results of operations are sensitive to changes in or uncertainty about industry and global economic conditions and their impact on consumer discretionary spending, particularly in the market for luxury design items. An economic downturn or recession, or slowing or stalled recovery therefrom in the United States or in other markets where we operate, may have a material adverse effect on our business, financial condition, or results of operations. Our buyers may have less money for discretionary spending and may stop or reduce their purchases of our products or switch to our competitors, reducing demand for the luxury design items available on our online marketplace. This would cause sales through our online marketplace to decline and adversely impact our business. Consumer purchases of luxury design items have generally declined during periods of economic uncertainty, when disposable income is reduced, or when there is a reduction in consumer confidence. Other factors that may negatively influence consumer spending on luxury design items include unemployment levels, inflation, volatile exchange rates, higher taxes, reduced access to credit, higher consumer debt levels, reductions in net worth, declines in asset values, home foreclosures and reductions in home values, fluctuating interest rates, changes to economic policy, fluctuating fuel and other energy costs, fluctuating commodity prices, government shutdowns, financial distress caused by bank failures, concerns about the stability and liquidity of certain financial institutions, volatility or disruption in the capital markets, a global health pandemic, international trade disputes, or geopolitical instability. Economic conditions may also be affected by global health crises, natural disasters, such as earthquakes, hurricanes, floods, severe storms, and wildfires, and wars, social unrest, political tensions, or other unexpected events, which may include further embargoes, regional instability, and geopolitical shifts that may adversely impact our business and operating results to an extent that cannot be predicted. Such economic uncertainty and decrease in the rate of purchases of luxury design items may slow the rate at which sellers choose to list their items with us, which could result in a decrease of items available through our online marketplace.

There is also a risk that if prolonged economic downturn or acute recession or uncertainty persist for a long time or worsen, consumers may make long-lasting changes to their spending habits, including less frequent discretionary purchases on a more permanent basis. These and other macroeconomic factors could adversely affect our business, financial condition, and results of operations. We may incur expenses or delays relating to such events outside of our control, which could have a material adverse impact on our business, operating results, and financial condition.

National retailers and brands set their own retail prices and promotional discounts on new luxury design items, which could adversely affect our value proposition to our buyers.

National retailers and brands set pricing for new luxury design items. Although the luxury design items available through our online marketplace are generally exclusive, one-of-a-kind products, promotional pricing by these parties may nonetheless adversely affect the value of luxury design items listed with us, and, in turn, our GMV and results of operations. In order to attract buyers to our online marketplace, the prices for the luxury design items sold through our online marketplace may need to be lowered in order to compete with these pricing strategies, which could negatively affect GMV and in turn, our net revenue. Any of the foregoing risks could adversely affect our business, financial condition, and results of operations.

If we fail to successfully anticipate and respond to changing preferences among our sellers and buyers, our ability to grow our business and our results of operations may suffer.

Our success is in large part dependent upon our ability to anticipate and identify trends in the market for luxury design items in a timely manner and to curate and obtain listings of luxury design items that address those trends. Consumer preferences can change quickly and may differ across generations and cultures. We use data science to predict seller and buyer preferences, and there can be no assurance that our data science will accurately anticipate seller or buyer requirements. Lead times relating to these changing preferences may make it difficult for us to respond rapidly to new or changing trends. To the extent we do not accurately predict the evolving preferences of our buyers or are unable to identify sellers of luxury design items who address such buyer preferences, our ability to grow our business and our results of operations would suffer.

If we fail to successfully expand our business model to encompass additional product verticals in a timely and cost-effective manner, our ability to increase our market share would suffer, which in turn could negatively impact our business, financial condition, and results of operations.

We intend to deepen our penetration in our existing verticals for luxury design items and continue to explore additional verticals to serve existing, and attract new, sellers and buyers. If these additional verticals do not attract new sellers or buyers, our revenue may fall short of expectations, our brand and reputation could suffer, and we may incur expenses that are not offset by revenue. In addition, our business may suffer if we are unable to attract new and repeat sellers that supply the necessary high-end, appropriately priced, and in-demand luxury design items in these additional verticals, and these verticals may also have a different range of margin profiles than the pieces currently sold through our online marketplace. Additionally, as we enter new verticals, potential sellers may demand lower commissions than our current verticals, which would adversely

affect our take rate and results of operations. Expansion of our offerings may also strain our management and operational resources, specifically the need to hire and manage additional authentication and market experts. We may also face increased competition from companies that are more focused on these verticals. If any of these were to occur, it could damage our reputation, limit our growth, and harm our results of operations.

If we fail to maintain and promote our brand and reputation, our business, market position, and future growth could suffer.

We believe that maintaining our brand reputation is critical to driving seller and buyer engagement and trust. An important goal of our brand promotion strategy is establishing trust with our seller and buyer network. Maintaining our brand will depend largely on our ability to continue providing our sellers with service that is consistent with the level of quality associated with the luxury design items they are listing and on the quality of our vetting specialists who represent our brand to new and existing sellers. Our vetting specialists cultivate relationships with our seller base and vet the luxury design items that our sellers want to list. While we do assess the qualifications of all vetting specialists, this may not prevent illegal, improper, or otherwise inappropriate actions, such as theft, from occurring in connection with our services. Any negative publicity related to the foregoing could adversely affect our reputation and brand or could negatively affect demand for our services and harm our business, financial condition, and results of operations.

For buyers, maintaining our brand requires that we foster trust through authentication and responsive and effective customer service, as well as ensuring that we have vetted sellers. If we fail to provide sellers or buyers with the service and experience they expect, or if we receive seller or buyer complaints or negative publicity about our online marketplace services, merchandise, delivery times or customer support, whether justified or not, the value of our brand would be harmed and our business may suffer.

If our marketing efforts are not effective, our ability to grow our business and maintain or expand our market share could suffer.

Maintaining and promoting awareness of our online marketplace is important to our ability to retain existing, and to attract new, sellers and buyers. To help facilitate our future growth and profitability, we are investing in our advertising, promotion, public relations, and marketing programs. These brand promotion activities may not yield increased revenue and the efficacy of these activities will depend on a number of factors, including our ability to do the following:

•determine the effectiveness for advertising, marketing, and promotional expenditures;

•select the right markets, media, and media vehicles in which to advertise;

•identify the most effective and efficient level of spending in each market, media, and media vehicle; and

•effectively manage marketing costs, including creative and media expenses, to maintain acceptable seller and buyer acquisition costs.

We may adjust or re-allocate our advertising spend across channels, product verticals, and geographic markets to optimize the effectiveness of these activities. We may increase advertising spend in future periods to continue driving our growth.

Implementing new marketing and advertising strategies also could increase the risk of devoting significant capital and other resources to endeavors that do not prove to be cost effective or provide a meaningful return on investment. We also may incur marketing and advertising expenses significantly in advance of recognizing revenue associated with such expenses and our marketing and advertising expenditures may not generate sufficient levels of brand awareness or result in increased revenue. Even if our marketing and advertising expenses result in increased sales, the increase might not offset our related expenditures. If we are unable to maintain our marketing and advertising channels on cost-effective terms or replace or supplement existing marketing and advertising channels with similarly or more effective channels, our marketing and advertising expenses could increase substantially, our seller and buyer base could be adversely affected, and our business, results of operations, financial condition, and brand could suffer.

We rely on third parties to drive traffic to our website, and these providers may change their algorithms or pricing in ways that could damage our business, operations, financial condition, and prospects.

We rely in part on digital advertising, including search engine marketing, to promote awareness of our online marketplace, grow our business, attract new, and increase engagement with existing, sellers and buyers. In particular, we rely on search engines, such as Google, and the major mobile app stores as important marketing channels. Search engine companies change their search algorithms periodically, and our ranking in searches may be adversely impacted by those changes. Search engine companies or app stores may also determine that we are not in compliance with their guidelines and penalize us as a result. If search engines change their algorithms, terms of service, display, or the featuring of search results, determine we are out of compliance with their terms of service or if competition increases for advertisements, we may be unable to cost-effectively add sellers and buyers to our website and apps. Our relationships with our marketing vendors are not long-term in nature and do not

require any specific performance commitments. In addition, many of our online advertising vendors provide advertising services to other companies, including companies with whom we may compete. As competition for online advertising has increased, the cost for some of these services has also increased. Our marketing initiatives may become increasingly expensive and generating a return on those initiatives may be difficult. Even if we successfully increase revenue as a result of our paid marketing efforts, such increase may not offset the additional marketing expenses we incur.

If the mobile solutions available to sellers and buyers are not effective, the use of our platform could decline.

Visits and purchases made on mobile devices by consumers, including buyers, have increased significantly in recent years. The smaller screen size and reduced functionality associated with some mobile devices may make the use of our platform more difficult or less appealing to sellers and buyers. Visits to our online marketplace on mobile devices may not convert into purchases as often as visits made through personal computers, which could result in less revenue for us. Sellers are also increasingly using mobile devices to operate their businesses on our platform. If we are not able to deliver a rewarding experience on mobile devices, sellers’ ability to manage and grow their businesses may be harmed and, consequently, our business may suffer. Further, although we strive to provide engaging mobile experiences for sellers and buyers who visit our mobile website using a browser on their mobile device, we depend on sellers and buyers downloading our mobile apps to provide them the optimal mobile experience.

As new mobile devices and mobile platforms are released, we may encounter problems in developing or supporting apps for them. In addition, supporting new devices and mobile device operating systems may require substantial time and resources.

The success of our mobile apps could also be harmed by factors outside our control, such as:

•actions taken by providers of mobile operating systems or mobile app download stores;

•unfavorable treatment received by our mobile apps, especially as compared to competing apps, such as the placement of our mobile apps in a mobile app download store;

•increased costs in the distribution and use our mobile apps; or

•changes in mobile operating systems, such as iOS and Android, that degrade the functionality of our mobile website or mobile apps or that give preferential treatment to competitive products.

If our sellers or buyers encounter difficulty accessing or using our platform on their mobile devices, or if our sellers or buyers choose not to use our platform on their mobile devices, our growth prospects and our business may suffer.

We must continue to drive efficiencies in our operations or our business could suffer.

We seek to continue to drive efficiencies in our business operations. As we continue to add capacity, capabilities, and automation, our operations will become increasingly complex and challenging. While we expect these technologies to improve productivity in many aspects of our operations, including order processing, pricing, copywriting, authentication, photography and photo retouching, any flaws or failures of such technologies could interrupt and delay our operations, which in turn may harm our business. Our investment in technology to support these efforts may not be effective in driving productivity, maintaining, or improving the experience for sellers and buyers, or providing a meaningful return on investment. We also rely on technology from third parties. If these technologies do not perform in accordance with our expectations, third parties change the terms and conditions that govern their relationships with us, or if competition increases for the technology and services provided by third parties, our business may be harmed. In addition, if we are unable to add automation to our operations, we may be unable to reduce the costs of processing listings and orders, which could cause delays in buyers receiving their purchases. Any of these outcomes could harm our reputation and our relationships with our sellers and buyers.

If we fail to manage our growth effectively, or if we are unable to execute our business plan and grow our business, our results of operations, and financial condition could be materially and adversely harmed.

We have experienced rapid growth in our business in the past, such as in the number of sellers and the number of countries in which we have sellers and buyers, and we intend to continue to focus on growth, both in the United States and abroad. The growth of our business, if any, places significant demands on our management team and pressure to expand our operational and financial infrastructure. As we continue to grow, our operating expenses will increase. If we do not manage our growth effectively, the increases in our operating expenses could outpace any increases in our revenue and our business could be harmed. In addition, we have in the past experienced, and may in the future experience, slower growth rates. Although we continue to focus on growth and are evaluating various approaches and alternatives to execute on our business strategies, the outcome of such evaluation or impact of any subsequent actions, if any, is uncertain. Failure to sustain or increase the growth of our business or to execute our business strategies would likely materially and adversely impact our business, financial condition, and results of operations.

We may require additional capital to support business growth, and we may be unable to obtain additional capital on acceptable terms, if at all, and any additional financing may dilute existing stockholders.

We believe that our existing cash, cash equivalents, and short-term investments will be enough to meet our anticipated cash needs for at least the next 12 months. We may require additional capital to grow our business, including the need to develop our online marketplace services, expand across and within product verticals, enhance our operating infrastructure, expand the markets in which we operate, and potentially acquire complementary businesses and technologies. Our future capital requirements will depend on many factors, including the emergence of competing online marketplaces and other adverse marketing developments; the timing and extent of our sales and marketing and technology and development expenditures; and any investments or acquisitions we may choose to pursue in the future. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through further issuances of equity or issuances of convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. In addition, we may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, and our business and prospects could suffer.

Our strategic initiatives to reduce our cost structure towards cash flow positive operations could have long-term adverse effects on our business operations, and we may not realize the operational or financial benefits from such actions, including achieving our cash flow positive operations.

Our cost-reduction initiatives related to achieving cash flow positive operations are subject to many risks and uncertainties and may have an adverse impact on our performance. For example, during the year ended December 31, 2023, we identified that we had excess vacancy in our office spaces and entered into a sublease agreement with a third party for approximately 78% of the rentable office space, which expanded to 100% of the rentable office space in January 2024. The sublease expires on the expiration date of our lease. This cost-reduction initiative could materially and adversely affect our business, cash flows, results of operations, profitability, and financial condition, due to factors beyond our control, including if our subtenant fails to make lease payments or otherwise defaults on their obligation to us as we could incur such payment obligations to our landlord and we may not be successful in realizing our anticipated savings and efficiencies. Additionally, in June 2023 and again in January 2025, we completed workforce reductions designed to reduce our operating costs and realign our investment priorities. We may not effectively execute on, or achieve the stated goals of, any future workforce reductions. For example, reductions in workforce may result in unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond the intended number of employees, and decreased employee morale. In addition, while certain positions may be eliminated, other functions necessary to our operations remain. We may be unsuccessful in distributing the duties and obligations of departed employees among our remaining employees and may need to incur additional and unanticipated costs to rehire or hire new personnel to perform such duties or may need to conduct additional reductions in workforce as we further redistribute such duties. If we are unable to realize the anticipated benefits, or experience significant adverse consequences, from any of our cost-reduction initiatives, our business, financial condition, and results of operations may be materially adversely affected.

Further expansion into markets outside of the United States is important to the growth of our business but will subject us to risks associated with operations abroad.

Expanding our community into markets outside of the United States is an important part of our strategy. Although we have a significant number of sellers and buyers outside of the United States, we have limited experience in developing local markets outside the United States. Also, visits to our online marketplace from buyers outside the United States may not convert into sales as often as visits from within the United States, including due to the impact of the strong U.S. dollar relative to other currencies. Our success in markets outside the United States will be linked to our ability to attract local sellers and buyers to our online marketplace and to localize our online marketplace in additional languages. If we are not able to do so, our growth prospects could be harmed.

In addition, competition is likely to intensify in the international markets where we operate and plan to expand our operations. Local companies based in markets outside the United States may have a substantial competitive advantage because of their greater understanding of, and focus on, those local markets. Some of our competitors may also be able to develop and grow in international markets more quickly than we will.

We have made substantial investments to expand to markets outside of the United States and continued expansion in markets outside of the United States may require significant additional financial investment. These investments include marketing to attract and retain new sellers and buyers, developing localized services and web platforms, forming relationships with third-party service providers, supporting operations in multiple countries, and potentially acquiring companies based

outside the United States and integrating those companies with our operations. These expansion efforts may not be successful and as a result, our business, results of operations, financial condition, and brand could suffer.

Doing business in markets outside of the United States also subjects us to increased risks and burdens such as:

•complying with different regulatory standards (including those related to the use of personal information, particularly in the European Union);

•managing and staffing operations over a broader geographic area with varying cultural norms and customs;

•adapting our online marketplace to local cultural norms and customs;

•potentially heightened risk of fraudulent transactions;

•limitations on the repatriation of funds and fluctuations of foreign exchange rates;

•exposure to liabilities under, and compliance challenges related to, multiple, conflicting, and changing governmental laws and regulations, including, but not limited to, employment, tax, privacy and data protection, U.S. anti-boycott authorities, anti-corruption, anti-money laundering and export control laws, including the U.S. Foreign Corrupt Practices Act of 1977, as amended, the UK Bribery Act of 2010, trade controls and sanctions administered by the U.S. Office of Foreign Assets Control, and similar laws and regulations in other jurisdictions;

•varying levels of Internet, e-commerce, and mobile technology adoption and infrastructure;

•our ability to enforce contracts and intellectual property rights in jurisdictions outside the United States; and

•barriers to international trade, such as tariffs or other taxes.

Sellers face similar risks in conducting their businesses across borders. Even if we are successful in managing the risks of conducting our business across borders, if sellers are not, our business could be adversely affected.

Finally, operating in markets outside of the United States requires significant management attention. If we invest substantial time and resources to expand our operations outside of the United States and cannot manage these risks effectively, the costs of doing business in those markets may be prohibitive or our expenses may increase disproportionately to the revenue generated in those markets.

We may incur significant losses from fraud, which would harm our results of operations.

We have in the past incurred and may in the future incur losses from various types of fraudulent transactions, including the use of stolen credit card numbers and claims that a buyer did not authorize a purchase. In addition to the direct costs of these losses, if the fraud is related to credit card transactions and becomes excessive, it could result in us paying higher fees or losing the right to accept credit cards for payment. Under current credit card practices, we may be found liable for fraudulent credit card transactions if we do not collect certain information from buyers, such as credit verification value numbers or cardholder signatures upon delivery of purchases. Our failure to adequately prevent fraudulent transactions could damage our reputation, result in litigation or regulatory action or lead to expenses that could substantially impact our results of operations.

Our business depends on continued and unimpeded access to the Internet, mobile networks, and third-party services.

To access our online marketplace, our sellers and buyers rely on access to the Internet or mobile networks. We also depend on widely adopted third-party platforms to reach our customers, such as popular mobile, social, search, and advertising offerings. Internet service providers may choose to disrupt or degrade access to our online marketplace or increase the cost of such access. Similarly, to download our mobile applications, application store providers must allow our applications to be listed. Internet service providers or application store providers could also attempt to charge us for providing access to our online marketplace.

Additionally, the adoption of any laws or regulations that adversely affect the popularity or growth in use of or access to the Internet or mobile networks or our services, including laws or regulations that undermine open and neutrally administered Internet access, could decrease user demand for our service offerings and increase our cost of doing business. In May 2024, the Federal Communications Commission (the “FCC”) released an order reclassifying broadband Internet access service as a telecommunication service rather than an information service, subject to the jurisdiction of the FCC under Title II of the Communications Act, reinstating the network neutrality rules it adopted in 2015 and then overturned in 2017. On January 2, 2025, however, the U.S. Court of Appeals for the Sixth Circuit issued a decision invalidating the reclassification and the network neutrality rules. Outside of the United States, government regulation of the Internet, including the idea of network neutrality, may be developing or non-existent. As a result, we could face discriminatory or anti-competitive practices that could impede our and sellers’ growth prospects, our buyer’s access to our platform, increase our costs, and harm our business.

Any significant disruption in service provided by, or termination of our relationship with, third parties that host our website, mobile app, or process payments made by buyers to sellers on our online marketplace could damage our reputation and result in loss of sellers and buyers, which in turn would harm our business and results of operations.

Our brand and ability to attract and retain sellers and buyers depends, in part, on the reliable performance of our cloud-hosted servers, network infrastructure and content delivery process. If the services provided by third parties are disrupted or if we are unable to maintain and scale the technology underlying our platform, our operations and business could suffer. The volume of traffic and activity on our online marketplace spikes on certain days and during certain periods of the year, such as during the fourth quarter due to the seasonality of our business, and any interruption would be particularly problematic if it were to occur at such a high-volume time.

The software and operation of the technology underlying our platform is expensive and complex, and we could experience operational failures. If we fail to accurately predict the rate or timing of the growth of our platform, we may be required to incur significant additional costs to maintain reliability. These costs could include, but are not limited to, adding additional hosting capacity or platforms, additional network providers, web application firewalls or other bot-mitigation technologies or additional content distribution networks. Additionally, as we rely on a fast, secure, and stable Internet, we could be required to adapt to any changes to global standards.

We have experienced, and expect that in the future we will experience, interruptions, delays, and outages in service and availability from time to time due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions, capacity constraints, and lack of network connectivity in one or more regions, which affect the availability of services on our platform and prevent or inhibit the ability of sellers and buyers to access our online marketplace or complete purchases on our online marketplace and app. Third-party providers host much of our technology infrastructure. Any disruption in their services, or any failure of our providers to handle the demands of our online marketplace could significantly harm our business and damage our reputation. Third-party providers also have systems that are constantly evolving, it is difficult to predict the challenges that we may encounter in developing our platform for use in conjunction with such third-party systems, and we may not be able to modify our integrations to assure its compatibility with the systems of other third parties following any of their changes to their systems. Further, if we experience failures in our technology infrastructure or do not expand our technology infrastructure successfully, then our ability to attract and retain sellers and buyers and our growth prospects and our business would suffer. We do not have control over the operations of the facilities of these third-party providers that we use. These facilities may be vulnerable to damage or interruption from natural disasters, cybersecurity attacks, terrorist attacks, power outages and similar events or acts of misconduct.

Our payments system depends on third-party providers and is subject to evolving laws and regulations.

We rely on third-party payment processors to process payments made by buyers or to sellers on our online marketplace.

We have engaged third-party service providers to perform underlying card processing, currency exchange, identity verification, and fraud analysis services. If these service providers do not perform adequately or if they terminate their relationships with us or refuse to renew their agreements with us on commercially reasonable terms, we will need to find an alternate payment processor and may not be able to secure similar terms or replace such payment processors in an acceptable timeframe. Further, the software and services provided by our third-party payment processors may not meet our expectations, contain errors or vulnerabilities, be compromised or experience outages. Any of these risks could cause us to lose our ability to accept online payments, make payments to sellers or conduct other payment transactions, any of which could make our platform less convenient and attractive and harm our ability to attract and retain sellers and buyers. In addition, sellers’ ability to accept orders could be negatively impacted and our business would be harmed. In addition, if these providers increase the fees they charge us, our operating expenses could increase. Alternatively, if we respond by increasing the fees we charge to sellers, some sellers may stop listing new items for sale.

The laws and regulations related to payments are complex and vary across different jurisdictions in the United States and globally. As a result, we are required to spend significant time and effort to comply with those laws and regulations. Any failure or claim of our failure to comply, or any failure by our third-party service providers to comply, could cost us substantial resources, could result in liabilities, or could force us to stop offering certain third-party payment services. As we expand the availability of new payment methods to our sellers and buyers in the future, we may become subject to additional regulations and compliance requirements.

Further, through our agreement with our third-party credit card processor, we are subject to payment card association operating rules and certification requirements, including the Payment Card Industry Data Security Standard. We are also subject to rules governing electronic funds transfers. Any change in these rules and requirements could make it difficult or impossible for us to comply.

We rely on Amazon Web Services (AWS) for a substantial portion of the computing, storage, data processing, networking, and other services for our online marketplace. A significant disruption of or interference with our use of AWS would negatively impact our operations and seriously harm our business.

AWS provides a distributed computing infrastructure as a service platform for our online marketplace’s business operations. Our primary production environment and data centers are on AWS, increasing our reliance on cloud infrastructure. Any transition of the cloud services currently provided by AWS to another cloud provider would be difficult to implement and would cause us to incur significant time and expense. Our products and services rely in significant part on continued access to, and the continued stability, reliability, and flexibility of AWS. Any significant disruption of, or interference with, our use of AWS would negatively impact our operations, and our business would be seriously harmed. In addition, if hosting costs increase over time and if we require more computing or storage capacity, our costs could increase disproportionately. If we are unable to grow our revenues faster than the cost of utilizing the services of AWS or similar providers, our business and financial condition could be adversely affected.

If our insurance coverage is insufficient or our insurers are unable to meet their obligations, our insurance may not mitigate the risks facing our business.

We contract for insurance to cover a number of risks and potential liabilities. Our insurance policies cover areas such as general liability, errors and omissions liability, employment liability, business interruptions, data breach, crime, product liability, property damage, and directors’ and officers’ liability. For certain types of business risk, we may not be able to, or may choose not to, acquire insurance. In addition, we may not obtain enough insurance to adequately mitigate the risks we face, or we may have to pay high premiums and/or deductibles for the coverage we do obtain. For example, we may not have adequate insurance coverage related to the actions of sellers on our platforms or for security incidents or data breaches. In evolving areas such as platform products liability, court decisions suggest that different jurisdictions may take differing positions on the scope of e-commerce platform liability for seller products. In some circumstances, a platform might be held liable for violations of applicable legal regimes by sellers and their products, such as intellectual property laws, privacy and security laws, product regulation, or consumer protection laws. Court decisions and regulatory changes in these areas may shift quickly, both in the United States and worldwide, and our insurance may be inadequate or unavailable to protect us from existing or newly developing legal risks.

Finally, while some sellers on our platforms may be insured for some or all of these risks, many small businesses do not carry any or sufficient insurance, and, even if a seller is insured, the insurance may not cover the relevant loss.

These factors may lead to increased costs for insurance, our increased liability, increased requirements or liability on sellers on our platforms, changes to our marketplaces or business model, or other damage to our brands and reputation.

Our cash, cash equivalents and short-term investments may be exposed to failure of our banking institutions.

While we seek to minimize our exposure to third-party losses of our cash, cash equivalents and short-term investments, our cash held in non-interest bearing and interest-bearing accounts that may exceed any applicable Federal Deposit Insurance Corporation (“FDIC”) insurance limits. Should events, including limited liquidity, defaults, non-performance, or other adverse developments occur with respect to the banks or other financial institutions that hold our funds, or that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, our liquidity may be adversely affected. For example, on March 10, 2023, Silicon Valley Bank (“SVB”) was unable to continue their operations and the FDIC was appointed as receiver for SVB and created the National Bank of Santa Clara to hold the deposits of SVB after SVB was unable to continue their operations. Although we did not have any material funds in SVB or other institutions that have been closed, we cannot guarantee that the banks or other financial institutions that hold our funds will not experience similar issues. If further failures in financial institutions occur where we hold deposits, we could experience additional risk. Any such loss or limitation on our cash, cash equivalents and short-term investments would adversely affect our business.

Risks Related to Human Capital

If we fail to attract and retain key personnel on our executive team or to effectively manage leadership succession, our business, financial condition, and results of operations could be adversely impacted.

Our success depends in part on our ability to attract and retain key personnel on our executive team, including our Chief Executive Officer, David S. Rosenblatt. Senior employees have left our company in the past and others may in the future. We often cannot anticipate such departures, and may not be able to promptly replace key leadership personnel. The loss of one or more of our key personnel or the inability to promptly identify a suitable successor to a key role could have an adverse effect on our business. Our key personnel are generally employed on an “at-will” basis.

If we fail to recruit and retain specialized employees and contractors, our business and operations could suffer.

Our ability to attract, retain, and motivate employees and contractors is important to our success. In addition, we may face challenges in connection with timely recruiting, hiring, and retaining qualified engineers to support our operations; and, other companies, including our competitors, may be successful in recruiting and hiring our employees and contractors. Qualified individuals are limited and in high demand, and we may incur significant costs to attract, develop and motivate them. Further, our future work environment strategy is continuing to evolve and may not meet the needs of our existing and potential future employees and they may prefer work models offered by other companies. If we fail to recruit and retain specialized employees and contractors, our ability to grow our business and our operations could suffer.

If we experience labor disputes or other disruption, it could harm our operations.

None of our employees are currently represented by a union. If our employees decide to form or affiliate with a union, we cannot predict the negative effects such future organizational activities will have on our business and operations. If we were to become subject to work stoppages, we could experience disruption in our operations, including delays in technology development, customer servicing and shipping, and increases in our labor costs which could materially adversely affect our business, financial condition, or results of operations.

Risks Related to Data Privacy and Cybersecurity, and Infrastructure

Our use and other processing of personal information and other data is subject to laws and obligations relating to privacy and data protection, and our failure to comply with such laws and obligations could harm our business.

Complex local, state, federal, and international laws, rules, and regulations apply to the collection, receiving, use, storing, retention, protection, security, disclosure, transfer, and other processing or handling of personal data about individuals, including our users and employees around the world. These privacy and data protection laws, rules, and regulations are quickly evolving, and we expect that there will continue to be new proposed laws, rules, regulations, and industry standards concerning privacy, data protection, and information security in the United States, UK, EU, and other jurisdictions in which we operate. See “Risk Factors--Risks Related to Legal, Regulatory Matters and Litigation--Expanding and evolving regulations in the areas of privacy and user data protection could create technological, economic, and cross-border business impediments to our business and those of our sellers.” If we fall short of our data protection obligations in countries in which we operate, we could face potential liability, regulatory investigations, and costly litigation, which may not be adequately covered by insurance. We have been incurring, and expect that we will continue to incur, costs related to compliance with such current and new local, state, federal, or international laws. In addition, any actual or perceived failure by us to comply with these laws, regulations, or other obligations may lead to significant fines, penalties, regulatory investigations, lawsuits, significant costs for remediation, damage to our reputation, or other liabilities.

The U.S. government has announced that it is reviewing the need for even greater regulation for the collection of information concerning consumer behavior on the Internet and mobile platforms, including regulation aimed at restricting certain targeted advertising practices, the use of location data and disclosures of privacy practices in the online and mobile environments, including with respect to online and mobile applications. In addition, state governments are engaged in similar legislative and regulatory activities. For example, the California Consumer Privacy Act (the “CCPA”) requires certain disclosures to California consumers regarding a business’ data processing activities, provides data privacy rights to California consumers, including the right to request a copy from a covered company of the personal information collected about them, the right to request deletion of such personal information, and the right to request to opt-out of certain sales of such personal information, and entails new operational requirements for covered companies to afford California consumers such rights. The CCPA establishes significant penalties for noncompliance. The California Privacy Rights Act (the “CPRA”), effective as of January 1, 2023, significantly modifies the CCPA, including by imposing additional obligations on covered companies and expanding consumers’ rights with respect to certain sensitive personal information and rights to object to sharing information for behavioral advertising purposes, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply. Comprehensive privacy legislation imposing similar obligations has been passed in nearly 20 additional states. Additionally, there has been discussion in Congress of a new comprehensive federal data protection and privacy law that, if passed, could create conflicting requirements and compliance with which could increase our potential liability, add layers of complexity to compliance in the U.S. market, increase our compliance costs, and adversely affect our business. In addition, all 50 states have laws that include obligations to provide notification of security breaches of computer databases that contain personal information to affected individuals, state officers, and others. Aspects of these U.S. state privacy laws and other laws and regulations relating to data protection, privacy, and information security, as well as their enforcement, remain unclear, and we may be required to modify our practices in an effort to comply with them.

Similarly, the UK General Data Protection Regulation and Data Protection Act 2018 (collectively, the “UK GDPR”) and the EU’s General Data Protection Regulation (“GDPR”) (the EU GDPR and UK GDPR together referred to as the “GDPR”), impose stringent data protection and privacy requirements on businesses in relation to the collection, processing, sharing,

disclosure, transfer, and other use of personal data of EU and UK data subjects. Complying with the GDPR remains an onerous and potentially costly obligation as interpretations of the specific requirements emerge through the courts, enforcement decisions and regulatory guidance.

In addition, the evolving framework governing the transfer of personal data subject to the GDPR to non-adequate jurisdictions presents significant challenges (e.g., where an EU seller or buyer transfers personal data to us in the U.S.) due to data localization requirements or limitations on cross-border data flows. In particular, the European Economic Area (“EEA”) and the UK have significantly restricted the transfer of personal information to the United States and other countries whose privacy laws they generally believe are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws, creating additional compliance hurdles for businesses.

Current Standard Contractual Clauses (“SCCs”), adopted by the European Commission in 2021, are limited to transfers where the data importer is not subject to the GDPR. This has left organizations without a clear legal framework for transfers between entities both subject to the GDPR, creating legal uncertainty and operational challenges. Additionally, interpretations of GDPR provisions by courts, along with the enforcement of national laws in EU member states, add complexity and potential inconsistencies in compliance requirements. The European Commission plans to address this gap by introducing new SCCs by the second quarter of 2025, following a public consultation in late 2024.

Additionally, companies that transfer personal information out of the EEA and UK to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers of personal information out of Europe for allegedly violating the EU GDPR’s cross-border data transfer limitations.

Until new SCCs are adopted and clear guidance is provided, there remains considerable uncertainty surrounding the future trajectory of the perception of such transfers and businesses face heightened risks, including regulatory scrutiny, enforcement actions, and legal disputes stemming from conflicting interpretations of these requirements or from inconsistencies from one jurisdiction to another, subject to differing interpretations and may be interpreted to conflict with our practices. Additionally, we are, and will continue to be, bound by contractual requirements applicable to our collection, use, processing and disclosure of various types of data, such as via Data Processing Addenda, including personal information, and may be bound by, or voluntarily comply with, self-regulatory or other industry standards relating to these matters.

Any failure or perceived failure by us or any third parties with which we do business to comply with these laws, rules and regulations, or with other obligations to which we or such third parties are or may become subject, may result in actions against us by governmental entities, private claims and litigation, the expenditure of legal and other costs and of substantial time and resources, and fines, penalties or other liabilities. Any such action would be expensive to defend, may require the expenditure of substantial legal and other costs and substantial time and resources, and likely would damage our reputation and adversely affect our business and results of operations. As such, delays or shortcomings in the adoption of new SCCs or continued legal uncertainty could exacerbate these risks, adversely affecting our business, financial condition, and operational outcomes.

In many jurisdictions, enforcement actions and consequences for non-compliance with protection, privacy, and information security laws and regulations are rising. In the U.S., possible consequences for non-compliance include enforcement actions in response to rules and regulations promulgated under the authority of federal agencies and state attorneys general and legislatures and consumer protection agencies. In the EU, data protection authorities may impose large penalties for violations of the data protection laws, including potential fines of up to €20 million or 4% of annual global revenue, whichever is greater. The authorities have shown a willingness to impose significant fines and issue orders preventing the processing of personal data on non-compliant businesses. Data subjects also have a private right of action, as do consumer associations, to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of applicable data protection laws. In addition, privacy advocates and industry groups have regularly proposed, and may propose in the future, self-regulatory standards that may legally or contractually apply to us. If we fail to follow these standards, even if no seller or buyer information is compromised, we may incur significant fines or experience a significant increase in costs.

Further, in view of new or modified federal, state, or foreign laws and regulations, industry standards, contractual obligations and other legal obligations, or any changes in their interpretation, we may find it necessary or desirable to fundamentally change our business activities and practices or to expend significant resources to modify our product and otherwise adapt to these changes. We may be unable to make such changes and modifications in a commercially reasonable manner or at all, and our ability to develop new products and features could be limited. Privacy, data protection and information security concerns, whether valid or not valid, may inhibit the use and growth of our online marketplace, particularly in certain foreign countries.

If sensitive information about our sellers and buyers or other third parties with whom we transact business is disclosed, or if we or our third-party providers are subject to cyber-attacks, use of our online marketplace could be curtailed, we may be exposed to liability, and our reputation would suffer.

Although we do not directly collect, transmit, and store personal financial information such as credit cards and other payment information, we utilize third-party payment processors who provide these services on our behalf. We also collect and store certain personally identifiable information provided by our sellers and buyers and other third parties with whom we transact business, such as names, email addresses, and the details of transactions. The collection, transmission, and storage of such information is subject to stringent legal and regulatory obligations. Some of our third-party service providers, such as identity verification and payment processing providers, also regularly have access to seller and buyer data. In an effort to protect sensitive information, we rely on a variety of security measures, including encryption and authentication technology licensed from third parties. However, advances in computer capabilities, increasingly sophisticated tools and methods used by hackers and cyber terrorists, new discoveries in the field of cryptography, or other developments may result in our failure or inability to adequately protect sensitive information. In addition, there may be scamming or phishing attempts, such as impersonating our personnel, in an effort to obtain personal information from our sellers and buyers or otherwise make inappropriate use of our online marketplace, which could expose us to liability, reduce seller and buyer satisfaction or confidence with our online marketplace, or damage our reputation.

Our platform is vulnerable to power outages, telecommunications failures, and catastrophic events, as well as computer viruses, worms, malicious code, break-ins, phishing attacks, denial-of-service attacks, ransomware, and other cyber-attacks. Any of these incidents could lead to interruptions or shutdowns of our platform, loss of data, or unauthorized disclosure of personally identifiable or other sensitive information. Cyber-attacks could also result in the theft of our intellectual property. As we gain greater visibility, we may face a higher risk of being targeted by cyber-attacks. Advances in computer capabilities, new technological discoveries, or other developments may result in cyber-attacks becoming more sophisticated and more difficult to detect.

Any failure or perceived failure by us to comply with our privacy policies, our privacy or data protection obligations to sellers and buyers or other third parties, or our privacy or data protection legal obligations, or any compromise of security that results in the unauthorized release or transfer of sensitive information, which may include personally identifiable information or other data, may result in governmental enforcement actions, litigation or public statements against us by consumer advocacy groups or others and could cause sellers and buyers to lose trust in us, which could have an adverse effect on our business. In addition to costs associated with investigating and fully disclosing a data breach, we could be subject to substantial costs to remedy the data breach, substantial monetary fines, or private claims by affected parties, and our reputation would likely be harmed.

We have experienced cybersecurity incidents in the past and may experience them in the future. Further, if we or our third-party service providers experience security breaches that result in online marketplace performance or availability problems or the loss or unauthorized disclosure of personal and other sensitive information, people may become unwilling to provide us the information necessary to set up seller and buyer accounts, and we could be subject to third-party lawsuits, regulatory fines, or other action or liability. Existing sellers and buyers may also stop listing new items for sale or decrease their purchases or close their accounts altogether. Further, any reputational damage resulting from breach of our security measures could create distrust of our company by sellers and buyers.

We and our third-party service providers may not have the resources or technical sophistication to anticipate or prevent all such cyber-attacks. Moreover, techniques used to obtain unauthorized access to systems change frequently and may not be known until launched against us or our third-party service providers. Security breaches can also occur as a result of non-technical issues, including intentional or inadvertent breaches by our employees or employees of our third-party service providers.

We expect to incur ongoing costs associated with the detection and prevention of security breaches and other security-related incidents. We may incur additional costs in the event of a security breach or other security-related incident. Any actual or perceived compromise of our systems or data security measures or those of third parties with whom we do business, or any failure to prevent or mitigate the loss of personal or other confidential information and delays in detecting or providing notice of any such compromise or loss could disrupt our operations, harm the perception of our security measures, damage our reputation, cause some sellers and buyers to decrease or stop their use of our online marketplace, and could subject us to litigation, government action, increased transaction fees, regulatory fines or penalties, or other additional costs and liabilities that could harm our business, financial condition, and results of operations.

We cannot be certain that our insurance coverage will be adequate for data handling or data security liabilities, that insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage or the occurrence of changes in our insurance policies, including premium increases or the imposition of large

deductible or co-insurance requirements, could have a material and adverse effect on our business, including our financial condition, results of operations, and reputation.

Use of social media, emails, phone calls, text messages, and push notifications may harm our reputation or subject us to fines or other penalties.

We use social media, emails, phone calls, text messages, and push notifications as part of our omni-channel approach to marketing and communications with sellers and buyers.

As laws and regulations evolve to govern the use of these channels, the failure by us, our employees, or third parties acting at our direction to comply with applicable laws and regulations in the use of these channels could adversely affect our reputation or subject us to fines or other penalties. For example, under the federal Telephone Consumer Protection Act (the “TCPA”), we face potential exposure to liability for certain types of telephonic communication with customers, including, but not limited to, text messages to mobile phones. Under the TCPA, plaintiffs may seek actual monetary loss or statutory damages of $500 per violation, whichever is greater, and courts may treble the damage award for willful or knowing violations. We are regularly subject to class-action lawsuits, as well as individual lawsuits, containing allegations that our businesses violated the TCPA. These lawsuits, and other private lawsuits not currently alleged as class actions, seek damages (including statutory damages) and injunctive relief, among other remedies. While a 2021 Supreme Court decision narrowed the applicability of the TCPA’s restrictions, plaintiffs continue to test the boundaries of the decision, and a few states, including Florida and Oklahoma, have adopted TCPA-like laws that similarly provide for statutory damages and a private right of action. Additional states may follow suit. A determination that there have been violations of the TCPA or other communications-based statutes could expose us to significant damage awards that could, individually or in the aggregate, materially harm our business.

In addition, our employees or third parties acting at our direction may knowingly or inadvertently make use of social media in ways that could lead to the loss or infringement of intellectual property, as well as the public disclosure of proprietary, confidential, or sensitive personal information of our business, employees, consumers, or others. Information concerning us or our sellers and buyers, whether accurate or not, may be posted on social media platforms at any time and may have an adverse impact on our brand, reputation, or business. The harm may be immediate without affording us an opportunity for redress or correction and could have a material adverse effect on our reputation, business, results of operations, financial condition, and prospects.

If the use of “cookie” tracking technologies is further restricted, regulated, or blocked, or if changes in technology cause cookies to become less reliable or acceptable as a means of tracking consumer behavior, the amount or accuracy of internet user information we collect would decrease, which could harm our business and operating results.

Cookies are small data files that are sent by websites and stored locally on an internet user’s computer or mobile device. We, and third parties who work on our behalf, collect data via cookies that is used to track the behavior of visitors to our sites, to provide a more personal and interactive experience, and to increase the effectiveness of our marketing. However, internet users can easily disable, delete, and block cookies directly through browser settings or through other software, browser extensions, or hardware platforms that physically block cookies from being created and stored.

Privacy regulations restrict how we deploy our cookies and this could potentially increase the number of internet users that choose to proactively disable cookies on their systems or cause or business partners, service providers, or vendors to no longer maintain their cookie processes. We may have to develop alternative systems to determine our clients’ behavior, customize their online experience, or efficiently market to them if clients block cookies or regulations introduce additional barriers to collecting cookie data.

Climate change may have an adverse impact on our business.

Risks related to rapid climate change may have an increasingly adverse impact on our business, our sellers’ businesses, and our buyers. Any of our primary locations and the locations of our buyers and sellers may be vulnerable to the adverse effects of climate change. For example, our New York headquarters has experienced, and is projected to continue to experience, climate-related events at an increasing frequency, including floods, severe storms, and heat waves. Furthermore, it is more difficult to mitigate the impact of these events on our employees in light of our flexible work model, which has allowed for a remote and dispersed work environment. Changing market dynamics, global policy developments, and the increasing frequency and impact of extreme weather events on critical infrastructure in the U.S. and elsewhere have the potential to disrupt our business and the transactions consummated between our sellers and buyers, which could have a material adverse effect on our financial condition and results of operations.

Risks Related to Legal, Regulatory Matters and Litigation

Our business is subject to a large number of U.S. and non-U.S. laws, many of which are evolving.

We are subject to a variety of laws and regulations in the United States and around the world, including those relating to traditional businesses, such as employment laws and taxation, and newer laws and regulations focused on the Internet, online commerce, and the resale market, such as payment systems, personal privacy, anti-spam, data security, electronic contracts, unfair and deceptive trade practices, and consumer protection. These laws and regulations are continuously evolving, and compliance is costly and can require changes to our business practices and significant management time and effort. Additionally, it is not always clear how existing laws apply to the Internet as many of these laws do not address the unique issues raised by the Internet or online commerce.

For example, laws relating to online privacy are evolving differently in different jurisdictions. Federal, state, and non-U.S. governmental authorities, as well as courts interpreting the laws, continue to evaluate the privacy implications of the use of third-party “cookies,” “web beacons,” and other methods of online tracking. The United States, the European Union, and other governments have enacted or are considering legislation that could significantly restrict the ability of companies and individuals to collect and store user information, such as by regulating the level of consumer notice and consent required before a company can employ cookies or other electronic tracking tools. In some cases, non-U.S. privacy, data protection, consumer protection and other laws and regulations are more restrictive than those in the United States. For example, the European Union traditionally has imposed stricter obligations under such laws than the United States. Consequently, the expansion of our operations internationally may require changes to the ways we collect and use consumer information.

Existing and future laws and regulations enacted by federal, state, or non-U.S. governments could impede the growth or use of the Internet or online commerce. It is also possible that governments of one or more countries may seek to censor content available on our online marketplace or may even attempt to block access to our online marketplace. If we are restricted from operating in one or more countries, our ability to attract or retain sellers and buyers may be adversely affected and we may not be able to grow our business as we anticipate.

Some providers of consumer devices and web browsers have implemented, or have announced plans to implement, ways to block tracking technologies which, if widely adopted, could also result in online tracking methods becoming significantly less effective. Any reduction in our ability to make effective use of such technologies could harm our ability to personalize the experience of buyers, increase our costs and limit our ability to attract new, and retain existing, sellers and buyers on cost-effective terms. As a result, our business could be adversely affected.

We strive to comply with all applicable laws, but they may conflict with each other, and by complying with the laws or regulations of one jurisdiction, we may find that we are violating the laws or regulations of another jurisdiction. Despite our efforts, we may not have fully complied in the past and may not in the future. If we become liable under laws or regulations applicable to us, we could be required to pay significant fines and penalties, and we may be forced to change the way we operate. That could require us to incur significant expenses or to discontinue certain services, which could negatively affect our business. Additionally, if third parties with whom we work violate applicable laws or our policies, those violations could result in other liabilities for us and could harm our business.

If we fail to comply with applicable laws or regulations, including those relating to the sale of antique and vintage items, we may be subject to fines, penalties, loss of licensure, registration, and approval, or other governmental enforcement action.

The sale of certain items through our online marketplace is subject to regulation, including by regulatory bodies such as the U.S. Consumer Product Safety Commission, the Federal Trade Commission, the U.S. Fish and Wildlife Service and other international, federal, state, and local governments and regulatory authorities. These laws and regulations are complex, vary from state to state and change often. We monitor these laws and regulations and adjust our business practices as warranted to comply. We list luxury design items from numerous sellers located throughout the United States and from over 75 countries, and the items listed by our sellers may contain materials such as fur, python, ivory, and other exotic animal product components, that are subject to regulation or cultural patrimony considerations. Our standard seller terms and conditions require sellers to comply with applicable laws when listing their items. Failure of our sellers to comply with applicable laws, regulations and contractual requirements could lead to litigation or other claims against us, resulting in increased legal expenses and costs. Moreover, failure by us to effectively monitor the application of these laws and regulations to our business, and to comply with such laws and regulations, may negatively affect our brand and subject us to penalties and fines.

Numerous U.S. states and municipalities, including the States of California and New York, have regulations regarding the handling of antique and vintage items and licensing requirements of antique and vintage dealers. Such government regulations could require us to change the way we conduct business or our buyers conduct their purchases in ways that increase costs or reduce revenues, such as prohibiting or otherwise restricting the sale or shipment of certain items in some locations. We could also be subject to fines or other penalties which in the aggregate could harm our business.

Additionally, the luxury design items our sellers sell could be subject to recalls and other remedial actions and product safety, labeling, and licensing concerns may require us to voluntarily remove selected items from our online marketplace. Such recalls or voluntary removal of items can result in, among other things, lost sales, diverted resources, potential harm to our reputation, and increased customer service costs and legal expenses, which could harm our results of operations.

Some of the luxury design items sold through our online marketplace on behalf of our sellers may expose us to product liability claims and litigation or regulatory action relating to personal injury, environmental, or property damage. We cannot be certain that our insurance coverage will be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms or at all. In addition, while all of our seller agreements contain a standard indemnification provision, certain sellers may not have sufficient resources or insurance to satisfy their indemnity and defense obligations which may harm our business.

We are subject to governmental export and import controls and anti-corruption laws and regulations that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws.

Our business activities are subject to various restrictions under U.S. export and similar laws and regulations, including the U.S. Department of Commerce’s Export Administration Regulations and various economic and trade sanctions administered by the OFAC. The U.S. export control laws and U.S. economic sanctions laws include restrictions or prohibitions on the provision of certain goods and services to U.S. embargoed or sanctioned countries and regions, governments, persons, and entities. We may also be subject to new or changing import and export laws and regulations in connection with the change in administration or otherwise, or actions by foreign governments in response to the same. In addition, various countries regulate the import of certain technology and have enacted or could enact laws that could limit our ability to provide sellers and buyers access to our online marketplace or could limit our sellers’ and buyers’ ability to access or use our services in those countries.

Our online marketplace could be utilized in violation of such laws, despite the precautions we take to prevent such violations. In the past, we may have facilitated transactions involving products or sellers that are the subject of U.S. sanctions or located in countries or regions subject to U.S. sanctions in apparent violation of U.S. economic sanction laws. In relation to certain compliance issues, we have submitted to OFAC an initial notification of voluntary self-disclosure concerning potential violations. If we fail to comply with these laws and regulations or are found to be in violation of U.S. sanctions or export control laws, including by facilitating unlawful transactions, we and certain of our employees could be subject to civil or criminal penalties, including the possible loss of export privileges and fines. We may also be adversely affected through penalties, reputational harm, loss of access to certain markets, or otherwise. Actions to remediate past potential violations may include internal reviews, voluntary self-disclosures, or other measures.

In addition, various countries regulate the import and export of certain encryption and other technology, including import and export permitting and licensing requirements, and have enacted laws that could limit the sale of items through our online marketplace or could limit our sellers’ and buyers’ ability to access our online marketplace in those countries. Changes in our online marketplace, or future changes in export and import regulations, may prevent our international sellers and buyers from utilizing our online marketplace or, in some cases, prevent the export or import of our sellers’ items to certain countries, governments, or persons. Any change in export or import regulations, economic sanctions, or related legislation or changes in the countries, governments, persons, or technologies targeted by such regulations, could result in decreased use of our online marketplace by, or in our decreased ability to facilitate transactions through our online marketplace among, existing or potential sellers and buyers internationally. Any decreased use of our online marketplace or limitation on our sellers’ ability to export or sell items would adversely affect our business, results of operations, and financial results.

We are also subject to various domestic and international anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, as well as other similar anti-bribery and anti-kickback laws and regulations. These laws and regulations generally prohibit companies, their employees, and their intermediaries from authorizing, offering, providing, and/or accepting improper payments or other benefits for improper purposes. These laws also require that we keep accurate books and records and maintain compliance procedures designed to prevent any such actions. Although we take precautions to prevent violations of these laws, our exposure for violating these laws increases as our international presence expands and as we increase sales and operations in foreign jurisdictions.

Claims, lawsuits, government investigations, judgments, settlements, and other legal proceedings could adversely affect our business, financial condition, and results of operations.

From time to time, we have, and may in the future, become involved in legal proceedings, claims, or litigation matters, such as matters incidental to the ordinary course of our business, including intellectual property, commercial, employment, class action, whistleblower, accessibility, and other litigation and claims, and governmental and other regulatory investigations and proceedings. Such matters, whether meritorious or not, can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability, damage our reputation, or require us to change our business

practices. Further, our general liability insurance may not cover all potential claims made against us or be sufficient to indemnify us for all liability that may be imposed. In addition, the expense of litigation and the timing of these expenses from period to period are difficult to estimate, subject to change, and could adversely affect our financial condition and results of operations. Because of the potential risks, expenses, and uncertainties of litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses, by agreeing to settlement agreements. Any of the foregoing could adversely affect our business, financial condition, and results of operations.

Expanding and evolving regulations in the areas of privacy and user data protection could create technological, economic, and complex cross-border business impediments to our business and those of our sellers.

Data protection has become a significant issue in the United States, countries in the European Union, and in many other countries in which we operate. In addition to the actual and potential changes in data protection laws described elsewhere in these Risk Factors, global developments in privacy and data security regulations have changed and may continue to change some of the ways we, our sellers, vendors, and other third parties collect, use, and share personal information and other proprietary or confidential information, and have created and will continue to create additional compliance obligations for us and our sellers, vendors, and other third parties.

In the European Union, the GDPR contains strict requirements for processing the personal data of individuals residing in E.U. member states, the EEA, and certain additional territories. The GDPR contains numerous requirements, including robust obligations on data controllers and data processors, greater rights for data subjects, including, for example, the “right to be forgotten,” and increased data portability, access, and redress rights for E.U. data subjects, security and accountability obligations (including stringent data breach notification requirements), increased rules for online and email marketing, compliance requirements related to our sellers, vendors, and other third parties, stronger regulatory enforcement regimes, and significantly heavier documentation and record-keeping requirements. The GDPR is subject to changing interpretations due to decisions of data protection authorities, courts, and related legislative efforts both E.U.-wide and in particular jurisdictions. Due to the GDPR and the implementation following Brexit of the U.K. GDPR, we may experience difficulty retaining or obtaining new E.U. or U.K. sellers, or current and new sellers may limit their selling into the European Union, due to the legal requirements, compliance cost, potential risk exposure, and uncertainty for them about their own compliance obligations with respect to the GDPR and U.K. GDPR. Furthermore, while the GDPR and U.K. GDPR remain substantially similar for the time being, the U.K. GDPR is currently under review in the United Kingdom and there may be further changes made to it over the next few years, including in ways that may differ from the GDPR, which could result in further compliance obligations. In addition, although our sellers are independent businesses, it is possible that a privacy authority could deem us jointly and severally liable for actions of our sellers or vendors, which would increase our potential liability exposure and costs of compliance, which could negatively impact our business. We could face potential liability, regulatory investigation, and costly litigation, which may not be adequately covered by insurance.

In the United States, rules and regulations governing data privacy and security include those promulgated under the authority of the Federal Trade Commission Act, the Electronic Communications Privacy Act, the Computer Fraud and Abuse Act, the CCPA and CPRA, and other state and federal laws relating to privacy, consumer protection, and data security. The CCPA and CPRA, and other recent and/or proposed state privacy laws, include requirements regarding the handling of personal information of consumers and households, including compliance and record keeping obligations, the right to request access to and deletion of their personal information, and the right to opt out of the sale and other uses of their personal information. Certain states provide a private right of action and statutory damages for data breaches.

Aspects of certain newly enacted state privacy statutes remain unclear, resulting in further legal uncertainty and potentially requiring us to modify our data practices and policies and to incur substantial additional costs and expenses in an effort to comply. If more stringent privacy legislation arises in the United States, E.U., or other jurisdictions where we operate, it could increase our potential liability and adversely affect our business, results of operations, and financial condition.

GDPR, CPRA, CCPA, and similar laws in other jurisdictions, and future changes to or interpretations of any of these laws, may continue to change the data protection landscape globally, may be potentially inconsistent or incompatible, and could result in potentially significant operational costs for internal compliance and risk to our business. Some of these requirements introduce friction into the buying and selling experience on our platforms and may impact the scope and effectiveness of our marketing efforts, which could negatively impact our business and future outlook. Complying with these laws and contractual or other obligations relating to privacy, data protection, data transfers, data localization, or information security may require us to make changes to our services to enable us or our customers to meet new legal requirements, incur substantial operational costs, modify our data practices and policies, and restrict our business operations. Any actual or perceived failure by us to comply with these laws, regulations, or other obligations may lead to significant fines, penalties, regulatory investigations, lawsuits, significant costs for remediation, damage to our reputation, or other liabilities. See “Risk Factors—Risks Related to Data Privacy and Cybersecurity, and Infrastructure—Our use and other processing of personal information and other data is subject to laws and obligations relating to privacy and data protection, and our failure to comply with such laws and obligations

could harm our business.” We may not be entirely successful in our compliance efforts due to various factors either within our control (such as limited internal resource allocation) or outside our control (such as a lack of vendor cooperation, new regulatory interpretations, or lack of regulatory guidance in respect of certain requirements).

We also publish privacy policies and other documentation regarding our collection, processing, use, and disclosure of personal data. Although we endeavor to comply with our published policies and documentation, we may at times fail to do so or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance, such as if our employees or vendors fail to comply with our published policies and documentation. We are or may also be subject to the terms of our own and third-party external and internal privacy and security policies, codes, representations, certifications, industry standards, publications and frameworks and contractual obligations to third parties related to privacy, information security, including contractual obligations to indemnify and hold harmless third parties from the costs or consequences of non-compliance with data protection laws, or other obligations.

Our sellers and vendors may have been and may now and in the future be subject to similar privacy requirements, which may significantly increase costs and resources dedicated to their compliance with such requirements. We have varying contractual and other legal obligations to notify relevant stakeholders of security breaches related to us or, in some cases, our third-party service providers. Many jurisdictions have enacted laws requiring companies to notify individuals, regulatory authorities, and others of security breaches involving certain types of data in some circumstances. In addition, our agreements with certain stakeholders may require us to notify them in the event of such a security breach. Such mandatory disclosures, even if only related to actions of a third-party vendor, are costly, could lead to negative publicity, may cause members of our communities to lose confidence in the effectiveness of our security measures and require us to expend significant capital and other resources to respond to and/or alleviate problems caused by the actual or perceived security breach, and may cause us to breach customer contracts. Our contracts, our representations or industry standards, to varying extents, require us to use industry-standard or reasonable measures to safeguard sensitive personal information or confidential information. A cyber incident or security breach could lead to claims by members of our communities, or other relevant stakeholders that we have failed to comply with such legal or contractual obligations. As a result, we could be subject to legal action or members of our communities could end their relationships with us. There can be no assurance that any indemnifications, limitations of liability or other remedies in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages.

We may not have adequate insurance coverage for security incidents or data breaches, including fines, judgments, settlements, penalties, costs, attorneys’ fees, and other impacts that arise out of incidents or breaches. If the impacts of a security incident or data breach, or the successful assertion of one or more large claims against us that exceeds our available insurance coverage, is of a type not subject to insurance, or results in changes to our insurance policies (including premium increases or the imposition of large deductible or co-insurance requirements), it could have an adverse effect on our business. In addition, we cannot be sure that our existing insurance coverage, cyber coverage, and coverage for errors and omissions will continue to be available on acceptable terms or that our insurers will not deny coverage as to all or part of any future claim or loss. Our risks are likely to increase as we continue to expand, grow our customer base.

Risks Related to Intellectual Property

If we cannot successfully protect our intellectual property, our business could suffer.

We rely on a combination of intellectual property rights, contractual protections, and other practices to protect our brand, proprietary information, technologies, and processes. We primarily rely on copyright and trade secret laws to protect our proprietary technologies, and processes, including the algorithms we use throughout our business. Others may independently develop the same or similar technologies and processes, or may improperly acquire and use information about our technologies and processes, which may allow them to provide a service similar to ours, which could harm our competitive position. Our principal trademark assets include the registered trademark “1stDibs” and our logos and taglines. Our trademarks are valuable assets that support our brand and consumers’ perception of our services and merchandise. We also hold the rights to the “1stDibs.com” Internet domain name and various related domain names, which are subject to Internet regulatory bodies and trademark and other related laws of each applicable jurisdiction. If we are unable to protect our trademarks or domain names, our brand recognition and reputation could suffer, we could incur significant expense establishing new brands and our results of operations could be adversely impacted. Although we do not currently have any issued patents, we may pursue patent protection for aspects of our technology in the future. We cannot predict whether any pending patent application will result in an issued patent that will effectively protect our intellectual property. Even if a patent issues, the patent may be circumvented or its validity may be challenged. In addition, we cannot provide assurance that every significant feature of technology and services will be protected by any patent or patent application. Further, to the extent we pursue patent protection for our innovations, patents applications may not result in issued patents, and patents that do issue or that we acquire may not provide us with any competitive advantages or may be challenged by third parties. There can be no assurance that any patents we obtain will adequately protect our inventions or survive a legal challenge, as the legal standards relating to the validity, enforceability, and scope of protection of patent and other intellectual property rights are uncertain.

Third parties have challenged and likely will continue to challenge our copyrights, trademarks, and other intellectual property and proprietary rights owned or held by us, or may knowingly or unknowingly infringe, misappropriate, or otherwise violate our copyrights, trademarks, or other proprietary rights. We allocate resources, and may be required to allocate significant resources, to monitor and protect our intellectual property rights, and the efforts we take to protect our proprietary rights may not always be sufficient. When violations occur, or if we detect violations, enforcing our intellectual property rights often requires pre-litigation tactics and may require litigation, which can be time-consuming, expensive, and divert management’s attention from standard business operations.

Although our enforcement efforts have not frequently encountered defenses or counterclaims challenging the validity or enforceability of our intellectual property rights, such challenges remain a risk. Courts may still determine that some of our intellectual property rights are unenforceable. If we are unable to cost-effectively protect our intellectual property rights, then our business could be harmed. An adverse decision in any of these legal actions could limit our ability to assert our intellectual property or proprietary rights, limit the value of our intellectual property or proprietary rights, or otherwise negatively impact our business, financial condition, and results of operations.

If the protection of our intellectual property and proprietary rights is inadequate to prevent use or misappropriation by third parties, the value of our brand and other intangible assets may be diminished, competitors may be able to more effectively mimic our service and methods of operations, the perception of our business and service to existing or potential sellers and buyers may become confused in the marketplace, and our ability to attract sellers and buyers may be adversely affected.

Intellectual property claims, which can be extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies in the future.

There is considerable intellectual property development activity in our market. Additionally, it is common for individuals and groups to purchase patents and other intellectual property assets for the purpose of making claims of infringement to extract licenses or settlements from companies like ours. Furthermore, we may be sued by third parties who seek to target us for actions taken by our sellers on our platform. From time to time, we receive notices that claim we have infringed, misappropriated, or misused other parties’ intellectual property rights. To the extent we gain greater public recognition, we may face a higher risk of being the subject of intellectual property claims. Third-party intellectual property rights may cover significant aspects of our technologies or business methods or block us from expanding our offerings.

Intellectual property claims against us, with or without merit, could be time-consuming and expensive to settle or litigate and could divert the attention of our management. Litigation regarding intellectual property rights is inherently uncertain due to the complex issues involved, and we may not always be successful in defending ourselves in such matters.

Potential litigants, including some of our competitors and patent holding companies, have the ability to dedicate substantial resources to enforcing their intellectual property rights. Any claims successfully brought against us could subject us to significant liability for damages and we may be required to stop using technology or other intellectual property alleged to be in violation of a third party’s rights. We also might be required to seek a costly license for third-party intellectual property. Even if a license is available, we could be required to pay significant royalties or submit to unreasonable terms, which would increase our operating expenses. We may also be required to develop alternative non-infringing technology, which could require significant time and expense. If we cannot license or develop technology for any allegedly infringing aspect of our business, we could be forced to limit our service and may be unable to compete effectively. Any of these results could harm our business.

We are subject to the terms of open source licenses because our platform incorporates open source software.

The software powering our online marketplace incorporates software covered by open source licenses. The terms of many open source licenses have not been interpreted by U.S. courts and there is a risk that the licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to operate our online marketplace. If we were to combine or connect our proprietary source code or software with open source software in a certain manner, we could, under certain of the open source licenses, be required to publicly release the source code of our software or to make our software available under open source licenses. To avoid the public release of the affected portions of our source code in the event of our inappropriate use of open source software, we could be required to expend substantial time and resources to re-engineer some or all of our software. In addition, use of open source software can lead to greater risks than use of third-party commercial software because open source licensors generally do not provide warranties or controls on the origin of the software. Use of open source software may also present additional security risks because the public availability of such software may make it easier for hackers and other third parties to determine how to compromise our platform. We have established processes to help alleviate these risks, but we cannot be sure that all of our use of open source software is in a manner that is consistent with our current policies and procedures or will not subject us to liability.

Risks Related to our Operations as a Public Company

If our internal control over financial reporting or our disclosure controls and procedures are not effective, we may not be able to accurately report our financial results, prevent fraud or file our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and may lead to a decline in our stock price.

We are required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act following the later of the date we are deemed to be an “accelerated filer” or a “large accelerated filer,” each as defined in the Exchange Act, or the date we are no longer an “emerging growth company,” as defined in the JOBS Act. In addition, as a public company, we are subject to Section 404(a), which requires us to include a report on our internal controls, including an assessment of the effectiveness of our internal controls and financial reporting procedures. Section 404 of the Sarbanes-Oxley Act (“Section 404”) requires that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluations, document our controls and perform testing of our key controls over financial reporting to allow management and our independent public accounting firm to report on the effectiveness of our internal control over financial reporting. Our testing, or the subsequent testing by our independent public accounting firm, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. If we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock would likely decline and we could be subject to lawsuits, sanctions, or investigations by regulatory authorities, which would require additional financial and management resources.

We may encounter difficulties in the timely and accurate reporting of our financial results, which would impact our ability to provide our investors with information in a timely manner. As a result, our investors could lose confidence in our reported financial information, and our stock price could decline.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). We are taking advantage of certain exemptions under the JOBS Act from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. We may take advantage of these exemptions for up to five years or until we are no longer an “emerging growth company,” whichever is earlier. We currently expect to cease to be an emerging growth company as of December 31, 2026, the last day of the fiscal year following the fifth anniversary of our IPO. Accordingly, we will likely become subject to additional disclosure and reporting requirements and related increased compliance costs.

In addition, Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period under the JOBS Act. Accordingly, our consolidated financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards.

If some investors find our common stock less attractive because we rely on any of these exemptions, there may be a less active trading market for our common stock and the market price of our common stock may be more volatile.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) in which the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we become a large accelerated filer, which means that we have been public for at least 12 months, have filed at least one annual report and the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last day of our then-most recently completed second fiscal quarter, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

Our operations as a public company require substantial costs and substantial management attention, and we may not be able to manage our operations as a public company effectively or efficiently.

As a public company, we have incurred, and expect to continue to incur, significant legal, accounting, and other expenses, and we must maintain effective disclosure and financial controls and corporate governance practices. Our management team and other personnel devote a substantial amount of time to, and we may not effectively, or efficiently manage our operations as

a public company, including our compliance with laws and regulations applicable to public companies. For example, we are subject to the reporting requirements of the Exchange Act, the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the rules and regulations of the SEC and Nasdaq. If, notwithstanding our efforts to comply with these laws, regulations, and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed. Further, failure to comply with these rules might make it more difficult for us to obtain some types of insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, on committees of our board of directors or as members of senior management. As such, we intend to continue to invest resources to comply with evolving laws, regulations and standards, and this investment has resulted, and may continue to result in, increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities.

We are subject to regulatory compliance requirements, including Section 404 of the Sarbanes-Oxley Act, and if we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud.

Section 404 requires that our management report on, and our independent auditors attest to, the effectiveness of our internal control structure and procedures for financial reporting. Since our second annual report following our IPO, we have been required to provide a management report on internal control over financial reporting. However, our auditors will not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 until we are no longer an “emerging growth company,” as defined in the JOBS Act.

Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. Section 404 compliance may divert internal resources and will take a significant amount of time and effort to complete. Implementing and maintaining effective internal controls has taken, and in the future will likely take, a significant amount of time and may require specific compliance training of our personnel. We have incurred, and expect to continue to incur, significant expense and devote substantial management effort to complying with the requirements of Section 404 of the Sarbanes-Oxley Act. For example, we have hired, and may in the future need to hire, additional accounting and finance personnel with system implementation experience and expertise regarding compliance with the Sarbanes-Oxley Act. We may be unable to identify and hire qualified professionals with requisite technical and public company experience when and as needed. In addition, new employees will require time and training to learn our business and operating processes and procedures. If we are unable to recruit and retain additional finance personnel as needed, or if we fail to maintain, or strengthen as needed, our financial reporting systems, infrastructure, and internal control over financial reporting, the quality and timeliness of our financial reporting may suffer, which could result in the identification of significant deficiencies or material weaknesses in our internal controls. Any consequences resulting from inaccuracies or delays in our reported consolidated financial statements could cause our stock price to decline and could harm our business, financial condition, and results of operations. We expect to continue to incur significant expense and devote substantial management effort toward ensuring compliance with Section 404.

In the future, we may discover areas of our internal controls that need improvement. If our auditors or we discover a material weakness or significant deficiency, the disclosure of that fact, even if quickly remedied, could reduce the market’s confidence in our consolidated financial statements and harm our stock price. Any inability to provide reliable financial reports or prevent fraud would harm our business. We may not be able to effectively and timely implement necessary control changes and employee training to ensure continued compliance with the Sarbanes-Oxley Act and other regulatory and reporting requirements. If we fail to successfully complete the procedures and certification and attestation requirements of Section 404, or if in the future our Chief Executive Officer, Chief Financial Officer or independent registered public accounting firm determines that our internal controls over financial reporting are not effective as defined under Section 404, we could be subject to investigations or sanctions by Nasdaq, the SEC, FINRA or other regulatory authorities. Furthermore, investor perceptions of the Company may suffer, and this could cause a decline in the market price of our shares of common stock. We cannot assure you that we will be able to fully comply with the requirements of the Sarbanes-Oxley Act or that management or, when applicable, our auditors will conclude that our internal controls are effective in future periods. Irrespective of compliance with Section 404, any failure of our internal controls could have a material adverse effect on our stated results of operations and harm our reputation.

Risks Related to Tax and Accounting Matters

We could be required to pay or collect sales taxes in jurisdictions in which we do not currently do so, with respect to past or future sales. This could adversely affect our business and results of operations.

An increasing number of states have considered or adopted laws that impose tax collection obligations on out-of-state sellers of goods. Additionally, the Supreme Court of the United States ruled in South Dakota v. Wayfair, Inc. et al (“Wayfair”), that online sellers can be required to collect sales tax despite not having a physical presence in the state of the

customer. In response to Wayfair, or otherwise, state or local governments and taxing authorities may adopt, or begin to enforce, laws requiring us to calculate, collect and remit taxes on sales in their jurisdictions. In addition, almost fully remote work environment can result in an increased number of states in which we have employees, which may result in sales tax obligations that we did not previously have. While we believe that we collect and remit sales taxes in every state that requires sales taxes to be collected, including states where we do not have a physical presence, the adoption of new laws by, or a successful assertion by the taxing authorities of, one or more state or local governments requiring us to collect taxes where we presently do not do so, or to collect more taxes in a jurisdiction in which we currently do collect some taxes, could result in substantial tax liabilities, including taxes on past sales, as well as penalties and interest. The imposition by state governments and taxing authorities of sales tax collection obligations on out-of-state e-commerce businesses could also create additional administrative burdens for us, put us at a competitive disadvantage if they do not impose similar obligations on our competitors, and decrease our future sales, which could harm our business and results of operations.

Our business and our sellers may be subject to sales tax, value-added tax (“VAT”), provincial taxes, goods and services tax, and other taxes.

The application of indirect taxes, such as sales and use tax, VAT, provincial taxes, goods and services tax, business tax and gross receipt tax, to businesses like ours and to our sellers and buyers is a complex and evolving issue. Significant judgment is required to evaluate applicable tax obligations and as a result amounts recorded are estimates and could change. In many cases, the ultimate tax determination is uncertain because it is not clear how existing statutes apply to our business or to sellers’ businesses. One or more states, the federal government, or other countries may seek to impose additional reporting, record-keeping, or indirect tax collection obligations on businesses like ours that facilitate online commerce. In addition, under EU VAT obligations for business to consumer e-commerce sellers and marketplaces, certain marketplaces are the deemed supplier when they facilitate certain cross-border business to consumer transactions of their third-party sellers. As a result, marketplaces may be liable to collect, report, and remit the VAT due from the consumer. The United Kingdom has similar VAT marketplace rules, and, in certain situations, may make facilitating marketplaces liable for the VAT collections for their overseas sellers. We continually monitor changes, such as these, which could materially affect our business operations. New taxes, both domestically and internationally, could also require us or sellers to incur substantial costs to capture data and collect and remit taxes. Such obligations add additional costs associated with tax collection, remittance, and audit requirements, which could make selling through our online marketplace less attractive and more costly for sellers, which could harm our business

Application of existing tax laws, rules or regulations are subject to interpretation by taxing authorities.

We are subject to income taxation at the federal, state, and local levels in the U.S. and also various international jurisdictions. The application of income and other tax laws is subject to interpretation. Although we believe our tax methodologies are compliant, a taxing authority’s final determination in the event of a tax audit could materially differ from our past or current methods for determining and complying with our tax obligations, including the calculation of our tax provisions and accruals, in which case we may be subject to additional tax liabilities, possibly including interest and penalties. Furthermore, taxing authorities have become more aggressive in their interpretation and enforcement of such laws, rules, and regulations over time, as governments are increasingly focused on ways to increase revenues. This focus has contributed to an increase in audit activity and stricter enforcement by taxing authorities. As such, additional taxes or other assessments may be in excess of our current tax reserves or may require us to modify our business practices to reduce our exposure to additional taxes going forward, any of which may have a material adverse effect on our business, results of operations, financial condition, and prospects.

We may experience fluctuations in our tax obligations and effective tax rate.

We are subject to taxation in the United States and in other jurisdictions. We record tax expense based on current tax payments and our estimates of future tax payments, which may include reserves for estimates of probable settlements of tax audits. At any time, multiple tax years could be subject to audit by various taxing jurisdictions. As a result, we expect that throughout the year there could be ongoing variability in our quarterly tax rates as taxable events occur and exposures are re-evaluated. Further, our effective tax rate in a given financial statement period may be adversely impacted by changes in tax laws, changes in the mix of revenue among different jurisdictions, changes to accounting rules, and changes to our ownership or capital structure. Fluctuations in our tax obligations and effective tax rate could adversely affect our business.

Amendments to existing tax laws, rules, or regulations or enactment of new unfavorable tax laws, rules, or regulations could have an adverse effect on our business and results of operations.

Many of the underlying laws, rules, and regulations imposing taxes and other obligations were established before the growth of the Internet and e-commerce. U.S. federal, state, and local taxing authorities are currently reviewing the appropriate treatment of companies engaged in Internet commerce and considering changes to existing tax or other laws that could levy sales, income, consumption, use, or other taxes relating to our activities, and/or impose obligations on us to collect such taxes. If such tax or other laws, rules, or regulations are amended, or if new unfavorable laws, rules or regulations are enacted, the

results could increase our tax payments or other obligations, prospectively or retrospectively, subject us to interest and penalties, decrease the demand for our services if we pass on such costs to our sellers or buyers, result in increased costs to update or expand our technical or administrative infrastructure, or effectively limit the scope of our business activities if we decided not to conduct business in particular jurisdictions. As a result, these changes may have a material adverse effect on our business, results of operations, financial condition, and prospects.

The Tax Cuts and Jobs Act of 2017 made a number of significant changes to the current U.S. federal income tax rules, including the reduction of the generally applicable corporate tax rate from 35% to 21%, the limitation of the tax deduction for net interest expense to 30% of adjusted taxable income (except for certain small businesses), the limitation of the deduction for net operating losses from taxable years beginning after December 31, 2017 to 80% of current year taxable income and the elimination of net operating loss carrybacks generated in taxable years ending after December 31, 2017 (though any such net operating losses may be carried forward indefinitely), and the modification or repeal of many business deductions and credits. Additionally, the Coronavirus Aid, Relief, and Economic Security Act, which, among other things, suspends the 80% limitation on the deduction for net operating losses in taxable years beginning before January 1, 2021, permits a five-year carryback of net operating losses arising in taxable years beginning after December 31, 2017 and before January 1, 2021, and generally caps the limitation on the deduction for net interest expense at 50% of adjusted taxable income for taxable years beginning in 2019 and 2020. It cannot be predicted whether, when, in what form, or with what effective dates, tax laws, regulations and rulings may be enacted, promulgated or issued, which could result in an increase in our or our stockholders’ tax liability or require changes in the manner in which we operate in order to minimize or mitigate any adverse effects of changes in tax law.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial net operating losses (“NOLs”), during our history. Unused NOLs may carry forward to offset future taxable income if we achieve profitability in the future, unless such NOLs expire under applicable tax laws. However, under the rules of Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its NOLs and other pre-change tax attributes to offset its post-change taxable income or other taxes may be limited. The applicable rules generally operate by focusing on changes in ownership among stockholders considered by the rules as owning, directly or indirectly, 5% or more of the stock of a company, as well as changes in ownership arising from new issuances of stock by the company. We completed formal studies through December 31, 2022 to determine if any ownership changes within the meaning of Sections 382 and 383 of the Code have occurred. As a result of the studies, we determined that although we experienced an ownership change on July 28, 2015, the limitation from the ownership change will not result in any of the NOLs or tax credits expiring unutilized. No additional ownership changes have occurred through the date of the most recent study. We are in the process of updating the formal study through December 31, 2024 to determine if any ownership changes within the meaning of IRC Section 382 and 383 have occurred. It is possible that we may experience an ownership change as a result of this study. In the event that we experience an ownership change within the meaning of Sections 382 and 383 of the Code as a result of the study or any future transactions in our stock, then we may be limited in our ability to use our NOL carryforwards to offset our future taxable income, if any.

Our reported results of operations may be adversely affected by changes in generally accepted accounting principles.

Generally accepted accounting principles are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported results of operations and could affect the reporting of transactions completed before the announcement of a change. It is difficult to predict the impact of future changes to accounting principles or our accounting policies, any of which could negatively affect our reported results of operations.

Risks Related to Our Common Stock

The price of our common stock has in the past been, and in the future may be, volatile, and you may lose all or part of your investment.

Our stock price has in the past been, and in the future may be, volatile and has experienced declines in the past and may experience future declines. As a result, you may not be able to resell your shares at or above the price at which your shares were acquired. The stock market in general has been highly volatile in light of the impacts from global adverse economic, political, or market conditions, including changes resulting from increases in inflation or interest rates, consumer credit conditions, consumer debt levels, employment rates, consumer confidence, supply chain disruptions, and geopolitical instability. Our stock price has fluctuated significantly in the past and will likely fluctuate in the future and may decline, resulting in a loss of some or all of your investment. For example, our common stock has traded both above and below our IPO price. The trading price and volume of our common stock could fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

•variations in our results of operations and other financial and operational metrics, including the key financial and operating metrics, as well as how those results and metrics disclosed in this Annual Report on Form 10-K compare to analyst and investor expectations;

In addition, if the market for technology stocks or the stock market in general experiences a loss of investor confidence, the price of our common stock, whether due to any of the foregoing factors or otherwise, could decline for reasons unrelated to our business, results of operations, or financial condition. The price of our common stock might also decline in reaction to events that affect other companies, even if those events do not directly affect us. Some companies that have experienced volatility in the trading price of their stock have been the subject of securities class action litigation. If we are the subject of such litigation, it could result in substantial costs and could divert our management’s attention and resources, which could adversely affect our business.

Sales of a substantial number of shares of our common stock in the public market, such as the perception that sales might occur, could cause the price of our common stock to decline.

The market price of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers, and significant stockholders, a large number of shares of our common stock becoming available for sale, or the perception in the market that such sales could occur. All of the shares of common stock sold in our IPO are freely transferable without restriction or additional registration under the Securities Act of 1933, as amended (the “Securities Act”).

We have registered all of the shares underlying outstanding options and any shares underlying other equity incentives we may grant in the future for public resale under the Securities Act. Accordingly, these shares will be able to be freely sold in the public market upon issuance to the extent permitted by any applicable vesting requirements. Sales of stock by these equity holders or the perception that such sales could occur could adversely affect the trading price of our common stock.

In addition, the registration of shares with existing registration rights would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by our affiliates as defined in Rule 144 under the Securities Act, which are subject to the limitations of Rule 144. Sales of securities by any of these stockholders or the perception that such sales could occur could adversely affect the trading price of our common stock.

We may issue additional common stock, convertible securities, or other equity in the future. We also expect to issue common stock to our employees, directors, and other service providers pursuant to our equity incentive plans. Additionally, as part of our business strategy, we may acquire or make investments in complementary companies, products or technologies and issue equity securities to pay for any such acquisition or investment. Any such issuances could be dilutive to investors and could cause the price of our common stock to decline. New investors in such issuances could also receive rights senior to those of holders of our common stock.

We cannot guarantee that our share repurchase program will be fully consummated or that it will enhance long-term stockholder value. Share repurchases could also increase the volatility of the trading price of our stock and will diminish our cash reserves.

Although our board of directors has authorized a share repurchase program that does not have an expiration date, the program does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares of our common stock. We cannot guarantee that the program will be fully consummated or that it will enhance long-term stockholder value. The program could affect the trading price of our stock and increase volatility, and any announcement of a termination of this program may result in a decrease in the trading price of our stock. In addition, this program will diminish our cash reserves.

Our actual results of operations may not meet our guidance and investor expectations, which would likely cause our stock price to decline.

From time to time, we may release guidance in our earnings releases, earnings conference calls, or otherwise, regarding our future performance that represent our management’s estimates as of the date of release. If given, this guidance, which will include forward-looking statements, will be based on projections prepared by our management. Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic, and competitive uncertainties and contingencies, many of which are beyond our control. The principal reason that we may release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. With or without our guidance, analysts, and other investors may publish expectations regarding our business, financial condition, and results of operations. We do not accept any responsibility for any projections or reports published by any such third parties. Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Our operating results with respect to one or more certain financial measures have in the past, and in the future may, come in below expectations, including market or analyst expectations. Any change in previously released guidance or in our practice of releasing guidance could materially and adversely affect the trading price of our common stock. Further, if our actual performance does not meet or exceed our guidance or investor expectations, the trading price of our common stock is likely to decline.

If securities analysts or industry analysts do not publish reports about our business, downgrade our common stock, or publish negative research or reports, our stock price and trading volume could decline.

The market price and trading market for our common stock will continue to be influenced by the research and reports that industry or securities analysts publish about us, our business, and our market. If one or more analysts adversely change their recommendation regarding our stock or change their recommendation about our competitors’ stock, our stock price could decline. If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline or become volatile.

We do not intend to pay dividends on our common stock, so any returns on your investment will be limited to changes in the value of our common stock.

We have never declared or paid any dividends on our common stock. We currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or paying any dividends for the foreseeable future. In addition, if we were to enter into loan or similar agreements in the future, these agreements may contain restrictions on our ability to pay dividends or make distributions. Any return to stockholders will therefore be limited to the increase, if any, in our stock price, which may never occur.

Our directors, executive officers and principal stockholders beneficially own a substantial percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.

Our directors, executive officers, greater than 5% stockholders and their respective affiliates beneficially own a significant percentage of our outstanding common stock. Therefore, these stockholders will continue to have the ability to influence us through their ownership position. If these stockholders act together, they may be able to determine all matters requiring majority stockholder approval. For example, these stockholders will be able to control elections of directors, amendments of our charter documents or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that other stockholders may feel are in their best interests.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, limit attempts by our stockholders to replace or remove our current management, and limit the market price of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:

•authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights, and preferences determined by our board of directors that may be senior to our common stock;

•require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;

•specify that special meetings of our stockholders can be called only by our board of directors, the Chairperson of our board of directors, or our Chief Executive Officer;

•establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of persons for election to our board of directors, which requires, without limitation, compliance with Rule 14a-19 under the Exchange Act, as applicable;

•establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;

•prohibit cumulative voting in the election of directors;

•provide that our directors may be removed only for cause;

•provide that vacancies on our board of directors may be filled by a majority of directors then in office, even if less than a quorum; and

•require the approval of our board of directors or the holders of at least 66 2/3% of our outstanding shares of capital stock to amend our bylaws and certain provisions of our certificate of incorporation.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in a broad range of business combinations with any interested stockholder for a period of three years following the date on which such stockholder became an interested stockholder. Any delay or prevention of a change of control transaction or changes in our management could cause our stock price to decline or could prevent or deter a transaction that a shareholder might support.

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce cash resources.

Our directors and executive officers may be subject to litigation for a variety of claims or disputes. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for any breach of fiduciary duties as directors, except liability for:

•any transaction from which the director derives an improper personal benefit;

•any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•any unlawful payment of dividends or redemption of shares; or

•any breach of a director’s duty of loyalty to the corporation or its stockholders.

Such limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission. Our amended and restated bylaws provide that we are required to indemnify our directors and officers to the fullest extent permitted by Delaware law and may indemnify our other employees and agents. Our amended and restated bylaws also provide that, on satisfaction of certain conditions, we will advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee, or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law. We have entered into, and intend to enter into, agreements to indemnify our directors and executive officers. With certain exceptions, these agreements provide for indemnification for related expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by any of these individuals in connection with any action, proceeding, or investigation. Such provisions in our amended and restated bylaws and our indemnification agreements may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. Such provisions may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders.

While we maintain directors’ and officers’ liability insurance, such insurance may not be adequate to cover all liabilities that we may incur, which may reduce our available funds to satisfy third-party claims and could harm our business, results of operations, and financial condition. Further, a stockholder’s investment may be harmed to the extent that we pay the costs of settlement and damage awards against our directors and executive officers as required by these indemnification provisions.

Our amended and restated certificate of incorporation and amended and restated bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, and provides that federal district courts will be the sole and exclusive forum for Securities Act claims, which could limit our stockholders’ ability to obtain what they believe to be a favorable judicial forum for disputes with us or our directors, officers, or other employees.

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware (or, if that court lacks subject matter jurisdiction, another federal or state court situated in the State of Delaware) shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on our behalf, (b) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (c) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (d) any action asserting a claim against us governed by the internal affairs doctrine (collectively, the “Delaware Forum Provision”). Our amended and restated certificate of incorporation and our amended and restated bylaws further provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts are the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”).

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, the enforceability of this provision is uncertain, and a court may determine that such provision will not apply to suits brought to enforce any duty or liability created by the Securities Act or any other claim for which the federal and state courts have concurrent jurisdiction. Further, compliance with the federal securities laws and the rules and regulations thereunder cannot be waived by investors in our common stock.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Accordingly, the Delaware Forum Provision does not designate the Court of Chancery as the exclusive forum for any derivative action arising under the Exchange Act, as there is exclusive federal jurisdiction in such instances.

Any person or entity purchasing or otherwise acquiring any interest in our capital stock shall be deemed to have notice of and consented to the Delaware Forum Provision and the Federal Forum Provision of our bylaws described above. These choice of forum provisions may impose additional litigation costs on stockholders in pursuing any such claims. Additionally, these choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, or other employees. Alternatively, if a court were to find these provisions of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, and results of operations and result in a diversion of the time and resources of our management and board of directors.

In addition, while the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require claims under the Securities Act be brought in federal court are “facially valid” under Delaware law, there is uncertainty as to whether other courts will enforce our Federal Forum Provision. If the Federal Forum Provision is found to be unenforceable, we may incur additional costs associated with resolving such matters. The Federal Forum Provision may also impose additional litigation costs on stockholders who assert that the provision is not enforceable or invalid. The Court of Chancery of the State of Delaware and the federal district courts of the United States may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our stockholders.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Risk Management and Strategy

We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as our business depends on both buyers and sellers trusting that their shopping experience with us is both reliable and safe. We have integrated cybersecurity risk management into our broader risk management framework in many ways, including (i) our regular updates to the Audit Committee, (ii) our information technology and security related internal controls and (iii) our global incident response and vulnerability management programs.

We view cybersecurity as a shared responsibility across the Company. All employees are required to complete yearly security training, and we periodically perform tabletop exercises with management participation. Further, our cross-functional teams work together to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. We use various security tools and processes to help prevent, identify, escalate, investigate, resolve and recover from identified vulnerabilities and security incidents in a timely manner, including, but not limited to, internal reporting, monitoring and detection tools and a vulnerability identification program.

Recognizing the complexity and evolving nature of cybersecurity threats, we engage with a range of external experts, including cybersecurity consultants in evaluating and testing our risk management systems. These partnerships enable us to leverage specialized knowledge and insights, with a goal of ensuring our cybersecurity strategies and processes remain at the forefront of industry best practices. Our collaboration with these third parties includes regular audits, threat assessments, and consultation on security enhancements.

In order to mitigate data or security incidents that may originate from third party vendors or suppliers, we conduct both privacy and security assessments to properly identify, prioritize, assess and remediate any third party risks, and require security and privacy addenda to our contracts where applicable.

The nature of our business exposes us to cybersecurity threats and attacks that can lead to the unauthorized acquisition or access, compromise, loss, misuse or theft of our data, including personal information, confidential information or intellectual property. As of the date of this Annual Report on Form 10-K, we are not aware of any material incidents or risks from cybersecurity threats that have materially affected us, including our business strategy, results of operations, or financial condition. For a discussion of how material risks from cybersecurity threats could materially affect us, see “Risk Factors—Risks Related to Privacy, Cybersecurity, and Infrastructure—If sensitive information about our sellers and buyers or other third parties with whom we transact business is disclosed, or if we or our third-party providers are subject to cyber-attacks, use of our online marketplace could be curtailed, we may be exposed to liability, and our reputation would suffer.”

Governance

Our Board of Directors is ultimately responsible for the Company's risk oversight, including cybersecurity and privacy risks. Our Board of Directors has delegated responsibility for oversight of cybersecurity risks to the Audit Committee. The Audit Committee comprises board members with diverse expertise, including risk management, technology, and finance, equipping them to oversee cybersecurity risks effectively. Our Audit Committee is charged with reviewing and discussing our policies with respect to risk assessment and risk management, which includes overseeing our major financial, privacy, security, cybersecurity, and technology risk exposures and the steps our management has taken to monitor and control these exposures. At the management level, our Head of Engineering and the system operations team are primarily responsible for identifying, assessing, monitoring, and managing cybersecurity. Our team also regularly partners with a firm with cybersecurity specialists, implementing best practices and building a cybersecurity framework around identifying, protecting, detecting, responding, and recovering from cybersecurity threats. The Audit Committee receives reports from senior management, including our periodic committee meetings, which include, on a rotating basis, in-depth presentations on specific areas of risk and regular enterprise risk management updates.

In addition to our scheduled meetings, our Global Incident Response Plan ensures that significant developments or incidents, even if immaterial to us, are reviewed regularly by a cross-functional team to determine whether further escalation to the Audit Committee is appropriate, ensuring the committee's and the Board of Directors’ oversight is timely and responsive. Our Global Incident Response Plan also includes immediate actions to mitigate the impact and long-term strategies for remediation and prevention of future incidents.

Item 2. Properties

Our corporate headquarters are located in New York, New York. Effective January 2024, our corporate headquarters have been relocated to 300 Park Avenue South, New York, New York, where we currently lease approximately 13,000 square feet under a lease agreement that expires in December 2028. We also lease approximately 42,000 square feet in New York, New York, which we are currently subleasing to a third party. See Note 10, “Leases” for further discussion.

We believe that our facilities are suitable to meet our current needs and that, if we require additional space, we will be able to obtain additional facilities.

Item 3. Legal Proceedings

From time to time, we are involved in legal proceedings and subject to claims arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we believe that the resolution of current matters will not have a material adverse effect on our business, financial condition, or results of operations. Even if any particular litigation or claim is not resolved in a manner that is adverse to our interests, such litigation can have a negative impact on us because of defense and settlement costs, diversion of management resources from our business, and other factors.

Item 4. Mine Safety Disclosures

Not applicable.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information for Common Stock

Our common stock has been listed on the Nasdaq Global Market under the symbol “DIBS” since June 10, 2021. Prior to that date, there was no public trading market for our common stock.

Holders of Record

As of the close of business on February 24, 2025, there were 85 stockholders of record of our common stock. The actual number of holders of our common stock is greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers or other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

Dividend Policy

We have never declared or paid cash dividends on our capital stock. We intend to retain all available funds and future earnings and do not anticipate paying cash dividends in the foreseeable future. Any future decision to declare cash dividends will be made at the discretion of our Board of Directors, subject to applicable laws and will depend on a number of factors, including our financial condition, results of operations, capital requirements, contractual restrictions, general business conditions, and other factors that our Board of Directors think are relevant.

Sales of Unregistered Equity Securities

None.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

In August 2023, the Board of Directors authorized the Company to repurchase up to an aggregate of $20.0 million of its common stock (“2023 Stock Repurchase Program”). In June 2024, the Board of Directors authorized an increase to the Company’s 2023 Stock Repurchase Program to an aggregate repurchase amount of $25.5 million, and subsequently announced the completion of its 2023 Stock Repurchase Program. In August 2024, the Board of Directors authorized the Company to repurchase up to an aggregate of $10.0 million of its common stock (“2024 Stock Repurchase Program”). As of December 31, 2024, 6,443,522 shares have been purchased for a total cost of $31.6 million and approximately $3.8 million remains available for future purchases under the 2024 Stock Repurchase Program.

The following table presents details of our monthly share repurchases for the three months ended December 31, 2024:


Period	Total Number of Shares Purchased	Average Price Paid per Share (a)		Total number of Shares Purchased as Part of Publicly Announced Plans or Programs (b)	Approximate Dollar Value of Shares that May Yet be Purchased under the Plans or Programs (in thousands)
October 1, 2024 - October 31, 2024	314,946	$	4.42	314,946	$	7,693

(a) Average price per share includes broker commissions.

(b) On August 20, 2024, the Board of Directors authorized a 2024 Stock Repurchase Program to repurchase up to an aggregate of $10.0 million of our common stock.

The Company’s officers and directors are required to comply with the Company’s securities trading policy at all times, including during a repurchase program. The securities trading policy, among other things, prohibits trading in the Company’s securities when in possession of material non-public information and restricts the ability of certain officers or director from transacting in the Company’s securities during specific blackout periods, subject to certain limited exceptions, including transactions pursuant to a Rule 10b5-1 trading plan that complies with the conditions of Rule 10b5-1 of the Exchange Act.

Item 6. [Reserved]

Item 7. Management’s Discussion And Analysis of Financial Condition And Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements based upon current plans, expectations, and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” under Part I, Item 1A in this Annual Report on Form 10-K. Our historical results are not necessarily indicative of the results that may be expected for any period in the future.

Company Overview

1stDibs began over two decades ago with the vision of bringing the magic of the Paris flea market online by creating a listings site for top vintage and antique furniture sellers. The quality of our initial seller base enabled us to build a reputation in the design industry as a trusted source for unique luxury design. Since then, we have strengthened our brand as well as deepened and broadened our seller relationships. We launched our e-commerce platform in 2013 and transitioned to a full e-commerce marketplace model in 2016. As of December 31, 2024, we operate an e-commerce marketplace with approximately 5,900 unique sellers, compared to approximately 7,800 as of December 31, 2023. In 2024, we shifted our seller acquisition strategy and monetization approach to concentrate on fewer, but more highly engaged sellers. As of December 31, 2024, we had 7.0 million users compared to 6.3 million as of December 31, 2023, and approximately 1.8 million listings, compared to 1.7 million as of December 31, 2023. Users represent non-seller visitors who register on our website, including both buyers and prospective buyers, and are identified by a unique email address. Our online marketplace seller stock value, the sum of the listed stock value of all available products listed on our online marketplace, remained consistent year over year and exceeded $10.0 billion as of both December 31, 2024 and 2023. An individual listing’s stock value is calculated as the item’s current price multiplied by its quantity available for sale.

GMV remained flat year over year and was $362.3 million for each of the years ended December 31, 2024 and 2023. Our net revenue was $88.3 million for the year ended December 31, 2024, compared to $84.7 million for the year ended December 31, 2023, an increase of 4%. In the year ended December 31, 2024, we generated a net loss of $18.6 million and Adjusted EBITDA of $8.0 million, compared to a net loss of $22.7 million and Adjusted EBITDA of $13.3 million for the year ended December 31, 2023. See “Non-GAAP Financial Measures” for more information and for a reconciliation of net loss to Adjusted EBITDA, the most directly comparable financial measure calculated and presented in accordance with GAAP.

Restructuring Charges

In September 2022, we announced and implemented a restructuring plan to reduce operational costs and realign investment priorities involving the reduction of approximately 10% of our workforce. As a result of the reduction, we incurred approximately $0.7 million in restructuring charges in the year ended December 31, 2022, consisting primarily of employee severance and benefits costs.

In June 2023, we announced a workforce reduction designed to further reduce operating costs and further realign investment priorities involving the reduction of approximately 20% of our global workforce. As a result of the reduction, we incurred approximately $2.0 million in restructuring charges during the year ended December 31, 2023, consisting primarily of employee severance and benefits costs.

During the year ended December 31, 2024, the Company incurred $1.4 million of additional employee severance and benefits costs relating to a further workforce reduction. The majority of the accrued severance totaling $1.3 million as of December 31, 2024 is anticipated to be paid during the year ending December 31, 2025, while approximately $0.1 million is expected to be paid during the first quarter of 2026. See Note 2, “Summary of Significant Accounting Policies” for further discussion on restructuring charges.

Our Business Model

We generate revenue primarily from fees from our seller marketplace services as well as other services, including advertisements.

Seller Marketplace Services

Seller marketplace services consist of marketplace transactions, subscriptions, and listings, and accounted for substantially all of our net revenue in the years ended December 31, 2024, 2023, and 2022, respectively.

Marketplace Transaction Fees

Our sellers pay us a commission and processing fee for the successful sale of an item listed on our online marketplace. We have a commission fee structure that is a function of the item’s category and price. Our commission fees range from 5% to 50% of GMV and we charge processing fees, which are approximately 3% of the buyer’s total payment, net of expected refunds. Our marketplace transaction fees represent the majority of our net revenue and accounted for 74%, 71%, and 71% of our net revenue in the years ended December 31, 2024, 2023, and 2022, respectively.

Subscription & Listing Fees

We offer our sellers various subscription pricing tiers which allows them to choose the plan that best fits their business, with choices of a higher monthly subscription fee and lower commission rates or a lower monthly subscription fee and higher commission rates. Subscription fees accounted for 22%, 24%, and 24% of our net revenue in the years ended December 31, 2024, 2023, and 2022, respectively. Our ability to maintain the level of our annual subscription fee rates depends on our ability to continue to generate sales for our sellers, which in turn depends on our ability to drive GMV growth, as GMV increases the network effect on our online marketplace. We earn listing fees from sellers, on a per item basis, as directed by the seller to promote certain items at the seller’s discretion. Sellers do not pay a listing fee for a basic listing on our online marketplace, but can choose to pay for other listing fees, which provide promotional advantages over the basic listing. Listing fees accounted for 3%, 4%, and 2% of our net revenue in the years ended December 31, 2024, 2023, and 2022, respectively.

Other Services

Other services consist of other charges to our sellers including advertising revenues generated from displaying ads on our online marketplace and accounted for 1%, 1% and 3% of our net revenue in the years ended December 31, 2024, 2023, and 2022, respectively. Advertising revenue is generated when impression-based ads are displayed on our online marketplace on our sellers’ behalf.

Key Operating and Financial Metrics

We use the following key metrics and non-GAAP measures to evaluate our performance, identify trends affecting our business, and make strategic decisions:

•GMV;

•Number of Orders;

•Active Buyers; and

•Adjusted EBITDA (see “Non-GAAP Financial Measures” for a discussion of Adjusted EBITDA and a reconciliation of net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA).

For GMV, Number of Orders, and Active Buyers, these metrics are based on internal company data, assumptions, and estimates and are used in managing our business. We believe that these figures are reasonable estimates, and we actively take measures to improve their accuracy, such as eliminating known fictitious or duplicate accounts. There are, however, inherent challenges in gathering accurate data across large online and mobile populations. For example, individuals may have multiple email accounts in violation of our terms of service, which would result in an Active Buyer being counted more than once, thus impacting the accuracy of our number of Active Buyers. In addition, certain metrics, such as the number of Active Buyers, Number of Orders, and GMV are measured based on such numbers as reported in a given month, minus cancellations within that month. As we do not retroactively adjust such numbers for cancellations occurring after the month, the metrics presented do not reflect subsequent order cancellations. We regularly review and may adjust our processes for calculating these metrics to improve their accuracy. These key operating and financial metrics may vary from period to period and should not be viewed as indicative of other metrics.

Gross Merchandise Value

We define GMV as the total dollar value from items sold by our sellers through 1stDibs in a given month, minus cancellations within that month, and excluding shipping and U.S. sales taxes. GMV includes all sales reported to us by our sellers, whether transacted through the 1stDibs online marketplace or reported as an offline sale. We define “on-platform GMV” as GMV based only on sales placed or reported through the 1stDibs online marketplace, thus on-platform GMV is a subset of GMV. Offline sales consist of sales completed by a small number of sellers outside of our online marketplace and reported to us by these sellers in exchange for increased marketing exposure and/or slightly lower commission rates on both their on-platform and offline sales. We do not intend to add new sellers to this program and have not in the current year. On-platform GMV accounted for $346.3 million, or 96%, $346.6 million, or 96%, and $409.4 million, or 96%, of GMV in the years ended December 31, 2024, 2023 and 2022, respectively. We view GMV as a measure of the total economic activity generated by our online marketplace and as an indicator of the scale, growth, and health of our online marketplace. Our historical performance for GMV may not be indicative of future performance in GMV.

Number of Orders

We define Number of Orders as the total number of orders placed or reported through the 1stDibs online marketplace in a given month, minus cancellations within that month. Our historical performance for Number of Orders may not be indicative of future performance in Number of Orders.

Active Buyers

We define Active Buyers as buyers who have made at least one purchase through our online marketplace during the 12 months ended on the last day of the period presented, net of cancellations. A buyer is identified by a unique email address; thus an Active Buyer could have more than one account if they were to use a separate unique email address to set up each account. We believe this metric reflects scale, engagement and brand awareness, and our ability to convert user activity on our online marketplace into transactions. Our historical performance for Active Buyers may not be indicative of future performance in new Active Buyers.

Adjusted EBITDA

We define Adjusted EBITDA as net loss excluding depreciation and amortization, stock-based compensation expense, other income, net, provision for income taxes, gain on sale of business, and strategic alternative expenses. Adjusted EBITDA is a key performance measure used by our management and board of directors to assess our operating performance and the operating leverage of our business. We believe that Adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of the income and expenses that we exclude from Adjusted EBITDA. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results, enhances the overall understanding of our past performance and future prospects, and allows for greater transparency with respect to key financial metrics used by our management in their financial and operational decision-making. See “Non-GAAP Financial Measures” for more information and for a reconciliation of net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA.

Key Factors Affecting Our Performance

We believe that our performance and future success depend on a number of factors that present significant opportunities for us, including those discussed in Part I, Item 1, “Business,” but also pose risks and challenges, including those discussed in the section titled “Risk Factors,” and elsewhere in this Annual Report on Form 10-K.

Growth and Retention of our Active Buyers

Our success depends in part on our ability to grow and retain our Active Buyer base. Our number of Active Buyers was 64,306 as of December 31, 2024 compared to 60,716 as of December 31, 2023. The total Number of Orders placed or reported through the 1stDibs online marketplace was 139,239 for the year ended December 31, 2024, compared to 133,072 for the year ended December 31, 2023. We had no Active Buyers who represented 5% or more of on-platform GMV for the years ended December 31, 2024 or 2023. Active Buyers drive our on-platform GMV and net revenue and contribute to the network effects that allow us to attract new sellers and exclusive inventory.

During the year ended December 31, 2024, we retained 23% of the 2023 on-platform GMV from buyers acquired in 2023; consistent with the year ended December 31, 2023, where we also retained 23% of the 2022 on-platform GMV from buyers acquired in 2022. We define new buyers as those who placed their first order on our online marketplace. We categorize buyers into cohorts based on the date of their first purchase on the 1stDibs platform. GMV attributed to a buyer cohort represents the total dollar value from items purchased by that buyer cohort in a given period, minus cancellations within that period and excluding shipping and U.S. sales taxes. To calculate the percentage of buyers retained, we divide total GMV in a specific period for a given cohort by the GMV of that cohort in the prior period. Similar to GMV and net revenue, we believe these metrics have been negatively impacted, directly and indirectly, by macroeconomic factors.

The figures below represent our on-platform GMV from our online marketplace by buyer cohort for the year ended December 31, 2024.

New buyers represented 38%, 35%, and 37% of GMV for the years ended December 31, 2024, 2023 and 2022, respectively while returning buyers represented 62%, 65%, and 63% of GMV for the years ended December 31, 2024, 2023 and 2022, respectively.

Components of Results of Operations

Net Revenue

Our net revenue consists principally of seller marketplace services. Seller marketplace services primarily consist of marketplace transactions, subscriptions, and listing fees. Marketplace transaction fees are collected when sellers pay us commissions ranging from 5% to 50% of GMV, and processing fees, which are approximately 3% of the buyer’s total payment, net of expected refunds. If a seller accepts a return or refund of an on-platform purchase, the related commission and processing fees are refunded. Subscriptions provide access to our online marketplace, allowing sellers, who are our customers, to execute successful purchase transactions with buyers. We offer our sellers various subscription pricing tiers which allows them to choose the plan that best fits their business, with choices of a higher monthly subscription fee and lower commission rates or lower monthly subscription fee and higher commission rates. Listing fee revenue is collected when sellers pay us for promoting certain products on their behalf and at their discretion through our online marketplace. Advertisements consist of impression-based ads displayed on our online marketplace on the seller’s behalf.

Our revenue recognition policies are discussed under “Critical Accounting Policies” and Note 2, “Summary of Significant Accounting Policies,” to our consolidated financial statements.

Cost of Revenue

Cost of revenue includes payment processor fees and hosting expenses. Cost of revenue also includes expenses associated with payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with personnel supporting revenue-related operations and logistics, consulting costs, and amortization expense related to our capitalized internal-use software.

In certain transactions where our shipping services are elected by sellers, we facilitate shipping of items purchased from the seller to the buyer. The difference between the amount collected for shipping and the amount charged by the shipping carrier is included in cost of revenue in our consolidated statements of operations. We facilitate fulfillment and shipping, but do not take ownership of or manage inventory.

Gross Profit and Gross Margin

Gross profit is net revenue less cost of revenue, and gross margin is gross profit as a percentage of net revenue. Gross profit has been, and will continue to be, affected by various factors, including leveraging economies of scale, the costs associated with hosting our platform, the level of amortization of our internal-use software, the fluctuations in shipping costs including our ability to pass these costs on to buyers, and the extent to which we expand our operations. We expect that our gross margin will fluctuate from period to period depending on the interplay of these various factors.

Sales and Marketing

Sales and marketing expenses include payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with sales and marketing personnel, advertising expense, consulting costs, and promotional discounts offered to new and existing buyers. Advertising expenses consist primarily of costs incurred promoting and marketing our services, such as costs associated with acquiring new users through performance-based marketing, social media programs, email, and events. Promotional discounts and incentives represent incentives solely to end buyers and, therefore, are not considered payments made to our customers. Buyers are not our customers because access to the 1stDibs online marketplace is free for buyers, and we have no performance obligations with respect to buyers.

Technology Development

General and Administrative

General and administrative expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with finance, legal, facility and human resources related personnel, lease expense, net of sublease income, business liability insurance, accounting, professional fees, and depreciation of property and equipment. We expense all general and administrative expenses as incurred.

Provision for Transaction Losses

Provision for transaction losses primarily consists of transaction loss expense associated with our buyer protection program, including damages to products caused by shipping and transit, items that were not received or not as represented by the seller, and reimbursements to buyers at our discretion if they are dissatisfied with their experience. The provision for transaction losses also includes bad debt expense associated with our accounts receivable balance.

Comparison of the Years Ended December 31, 2024 and 2023

Net Revenue


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Net revenue	$	88,257	$	84,684	$	3,573	4	%

Net revenue was $88.3 million for the year ended December 31, 2024, as compared to $84.7 million for the year ended December 31, 2023. The increase of $3.6 million, or 4%, was primarily driven by various strategic initiatives we actioned to improve our take rates, including commission re-tiering.

Our marketplace transaction fees represent the majority of our net revenue and accounted for 74% and 71% of our net revenue for the years ended December 31, 2024 and 2023, respectively. Subscription fees accounted for 22% and 24% of our net revenue for the years ended December 31, 2024 and 2023, respectively.

Cost of Revenue


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Cost of revenue	$	24,831	$	25,111	$	(280)	(1)	%

Cost of revenue was $24.8 million for the year ended December 31, 2024, as compared to $25.1 million for the year ended December 31, 2023. The decrease of $0.3 million, or 1%, was primarily driven by a $0.5 million decrease in salaries and benefits resulting from decreases in average headcount from the prior period, primarily related to our reduction in workforce in June 2023, partially offset by annual compensation increases in March.

Gross Profit and Gross Margin

Gross profit was $63.4 million and gross margin was 71.9% for the year ended December 31, 2024, as compared to gross profit of $59.6 million and gross margin of 70.3% for the year ended December 31, 2023. The increase in gross profit and gross margin for the year ended December 31, 2024 was primarily driven by our initiatives to improve our take rates, contributing to an increase in net revenue, as well as our cost savings initiatives in the second half of 2023 which contributed to a decrease in our cost of revenue, as outlined above.

Operating Expenses

Sales and Marketing


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Sales and marketing	$	38,084	$	36,640	$	1,444	4	%

Sales and marketing expense was $38.1 million for the year ended December 31, 2024, as compared to $36.6 million for the year ended December 31, 2023. The increase of $1.4 million, or 4%, was primarily driven by a $2.7 million increase in performance-based marketing spend which contributed to an increase in GMV and net revenues during the first half of 2024 and again in the fourth quarter. This increase was partially offset by a $1.0 million decrease in salaries and benefits resulting from decreases in headcount, primarily related to our reduction in workforce in June 2023, partially offset by annual compensation increases in March.

Technology Development


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Technology development	$	21,165	$	21,644	$	(479)	(2)	%

Technology development expense was $21.2 million for the year ended December 31, 2024, as compared to $21.6 million for the year ended December 31, 2023. The decrease of $0.5 million, or 2%, was primarily driven by a $1.0 million decrease in salaries and benefits resulting from decreases in headcount, primarily related to our reduction in workforce in June 2023, which were partially offset by annual compensation increases in March, including a $0.3 million increase in stock-based compensation expense.

General and Administrative


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
General and administrative	$	27,372	$	28,587	$	(1,215)	(4)	%

General and administrative expense was $27.4 million for the year ended December 31, 2024, as compared to $28.6 million for the year ended December 31, 2023. The decrease of $1.2 million, or 4%, was primarily driven by a $1.7 million decrease in lease expense, net, primarily due to sublease income related to our August 2023 sublease for our former New York City corporate headquarters, and a $1.1 million decrease related to lower rates negotiated with vendors, including lower insurance expense. These decreases were partially offset by a $1.4 million increase in stock-based compensation expense, primarily due to equity grants which occur annually in March.

Provision for Transaction Losses


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Provision for transaction losses	$	3,020	$	3,729	$	(709)	(19)	%

Provision for transaction losses was $3.0 million for the year ended December 31, 2024, as compared to $3.7 million for the year ended December 31, 2023. The decrease of $0.7 million, or 19%, was primarily driven by a decrease in damage claims as a result of new policies implemented by us and in partnership with our carriers.

Other Income, Net


	Year Ended December 31,
(in thousands)	2024		2023		$ Change		% Change
Total other income, net	$	7,626	$	8,342	$	(716)	(9)	%

Other income, net was $7.6 million for the year ended December 31, 2024, as compared to $8.3 million for the year ended December 31, 2023. The decrease of $0.7 million, or 9%, was due primarily to interest income on our cash, cash equivalents, and short-term investments which decreased in the current year due to less cash, cash equivalents, and short-term investments as well as lower interest rates.

Non-GAAP Financial Measures

We have included Adjusted EBITDA, which is a non-GAAP financial measure, because it is a key measure used by our management team to help us to assess our operating performance and the operating leverage in our business. We also use this measure to analyze our financial results, establish budgets and operational goals for managing our business, and make strategic decisions. We believe that Adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of the income and expenses that we exclude from Adjusted EBITDA. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations, enhances the overall understanding of our past performance and future prospects, and allows for greater transparency with respect to key financial metrics used by our management in their financial and operational decision-making. We also believe that the presentation of this non-GAAP financial measure provides an additional tool for investors to use in comparing our core

business and results of operations over multiple periods with other companies in our industry, many of which present similar non-GAAP financial measures to investors, and to analyze our operating performance.

The non-GAAP financial measures presented may not be comparable to similarly titled measures reported by other companies due to differences in the way that these measures are calculated. The non-GAAP financial measures presented should not be considered as the sole measure of our performance and should not be considered in isolation from, or as a substitute for, comparable financial measures calculated in accordance with GAAP. Further, these non-GAAP financial measures have certain limitations in that they do not include the impact of certain expenses that are reflected in our consolidated statements of operations. Accordingly, these non-GAAP financial measures should be considered as supplemental in nature, and are not intended, and should not be construed, as a substitute for the related financial information calculated in accordance with GAAP. These limitations of Adjusted EBITDA include the following:

•The exclusion of certain recurring, non-cash charges, such as depreciation and amortization of property and equipment. While these are non-cash charges, we may need to replace the assets being depreciated in the future and Adjusted EBITDA does not reflect cash requirements for these replacements or new capital expenditure requirements;

•The exclusion of stock-based compensation expense, which has been a significant recurring expense and will continue to constitute a significant recurring expense for the foreseeable future, as equity awards are expected to continue to be an important component of our compensation strategy;

•The exclusion of other income, net, which includes interest income related to our cash, cash equivalents and short-term investments, and realized and unrealized gains and losses on foreign currency exchange;

•The exclusion of gain on sale of Design Manager, which is a one-time sale of our wholly owned subsidiary; and

•The exclusion of strategic alternative expenses in connection with capital return strategies, buy- and sell-side mergers, acquisitions and partnerships which include integration costs, sale of a business or subsidiary, business optimization costs related to revisions of operational objectives and priorities which include restructuring charges, in all cases outside the ordinary course.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net loss and our other GAAP results.

We define Adjusted EBITDA as our net loss, excluding: (1) depreciation and amortization; (2) stock-based compensation expense; (3) other income, net; (4) provision for income taxes; (5) gain on sale of business; and (6) strategic alternative expenses. The following table provides a reconciliation of net loss, the most directly comparable GAAP financial measure, to Adjusted EBITDA:

Seasonality

We have historically experienced increased sales during the fourth quarter holiday shopping season compared to the other quarters which has generally resulted in increased GMV and net revenue during the fourth quarter of each fiscal year. However, in the years ended December 31, 2023 and 2022 we did not experience meaningful increases and had seen decreases in GMV and net revenue in the fourth quarter, as we believed they had been adversely impacted, both directly and indirectly, by macroeconomic factors. In the year ended December 31, 2024, we saw a return to an increase in GMV and net revenues during the fourth quarter. Our cost of revenue and sales and marketing expenses generally follow this trend, with our highest costs being incurred in the fourth quarter; but similar to GMV and net revenues, cost of revenue and sales and marketing expenses have not followed this trend in the prior years due to macroeconomic factors. However, similar to the GMV and net revenue trend we saw in 2024, our cost of revenue and sales and marketing expenses also increased in the fourth quarter of the year ended December 31, 2024. As our growth rates fluctuate or other unforeseen factors arise, the impact of these seasonality trends on our results of operations may become more or less pronounced.

We enable fulfillment and shipping, but do not own or manage inventory. If our growth rates change, the impact of these seasonality trends on our results of operations may become more pronounced. We anticipate that gross margin may fluctuate from quarter to quarter based on variability in the costs associated with hosting our online marketplace and supporting order processing.

We intend to continue strategically investing in our technology development efforts, inclusive of investments in machine learning and artificial intelligence, to improve and expand our platform. We expect the majority of our technology development expenses will result from consulting and/or headcount-related expenses. We also intend to continue making strategic investments in marketing to drive future net revenue growth. We expect provision for transaction losses to vary based on fluctuations in GMV.

Liquidity and Capital Resources

As of December 31, 2024, we had cash, cash equivalents and short-term investments of $103.9 million and an accumulated deficit of $332.4 million. Net cash used in operating activities was $2.9 million in the year ended December 31, 2024. We expect operating losses and negative cash flows from operations to continue in the foreseeable future as we continue to strategically invest in growth activities. Our principal use of cash is to fund our operations including platform development to support our strategic initiatives and anticipated share repurchases under the 2024 Stock Repurchase Program.

Based on our current plans, we believe our existing cash, cash equivalents and short-term investments will be sufficient to fund our operations and capital expenditure requirements through at least the next 12 months. We expect to continue to incur substantial expenditures in the near term to support our ongoing activities. While management believes that our current cash, cash equivalents and short-term investments are sufficient to fund our operating expenses, capital expenditure requirements and any anticipated share repurchases under the 2024 Stock Repurchase Program for at least the next 12 months, we may need to borrow funds or raise additional equity to achieve our longer-term business objectives.

Our future capital requirements will depend on many factors, including:

•the emergence of competing online marketplaces and other adverse market developments;

•the timing and extent of our sales and marketing and technology development expenditures; and

•any investments, acquisitions or other similar strategic endeavors we may choose to pursue in the future.

A change in the outcome of any of these or other variables could significantly impact our operating plans, and we may need additional funds to meet operational needs and capital requirements associated with such plans. In addition, any future borrowings may result in additional restrictions on our business and any issuance of additional equity would result in dilution to investors. If we are unable to raise additional capital when we need it, it could harm our business, results of operations, and financial condition.

Stock Repurchase Program

As of December 31, 2024, 6,443,522 shares have been purchased for a total cost of $31.6 million since the commencement of both our 2023 and 2024 stock repurchase programs and approximately $3.8 million remains available for future purchases under the 2024 Stock Repurchase Program.

Cash Flows

The following table summarizes our cash flows for the periods indicated:


	Year Ended December 31,
(in thousands)	2024		2023
Net cash used in operating activities	$	(2,910)	$	(13,556)
Net cash provided by (used in) investing activities	22,291		(100,232)

Effect of exchange rate changes on cash, cash equivalents, and restricted cash	(29)		349
Net decrease in cash, cash equivalents, and restricted cash	$	(11,354)	$	(117,068)

Cash Flows from Operating Activities

Net cash used in operating activities was $2.9 million for the year ended December 31, 2024, and was driven primarily by a $3.3 million decrease in operating lease liabilities due to lease payments on our previous and current NYC headquarters, partially offset by our sublease income, a $1.7 million decrease in accounts payable and accrued expenses due to the timing of payments and invoices, and a $1.8 million decrease in other current liabilities and other liabilities related to payments for sales

and other indirect tax contingencies. These decreases were partially offset by a $2.1 million increase in payables due to sellers due to timing of the payments we make to our sellers.

Net cash used in operating activities was $13.6 million for the year ended December 31, 2023, and was driven primarily by net revenue decreasing at a faster pace than operating expenses as described in the “Results of Operations” section. Our changes in operating assets and liabilities were impacted by a negative change in operating lease liabilities of $2.8 million due to the continued lease payments on our prior NYC headquarters, a $1.5 million negative change in prepaid and other current assets primarily related to timing of prepayments including the current portion of a significant payment in the fourth quarter of 2023 relating to our platform hosting expense, and a $2.1 million negative change in other assets, primarily related to the long-term portion of the prepayment referenced above and the broker fee paid in connection with our subleasing of our prior NYC headquarters.

Cash Flows from Investing Activities

Net cash provided by investing activities was $22.3 million for the year ended December 31, 2024, and was driven primarily by $110.3 million maturities and sales of short-term investments, partially offset by $86.4 million purchases of short-term investments.

Net cash used in investing activities was $100.2 million for the year ended December 31, 2023, and was primarily due to $191.1 million of purchases of short-term investments, offset by $92.7 million of maturities of short-term investments.

Cash Flows from Financing Activities

Net cash used in financing activities was $30.7 million for the year ended December 31, 2024, and was driven primarily by $27.7 million in purchases of our common stock as part of our 2023 and 2024 stock repurchase programs and $3.8 million of payments for taxes related to net share settlements of stock-based compensation awards, partially offset by $0.8 million in proceeds from the exercise of stock options.

Net cash used in financing activities was $3.6 million for the year ended December 31, 2023 due mainly to the purchase of $3.4 million of our common stock as part of our 2023 Stock Repurchase Program.

Off-Balance Sheet Arrangements

For the periods presented, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Recent Accounting Pronouncements

See Note 2, “Summary of Significant Accounting Policies” to our consolidated financial statements, for a description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations or cash flows.

Emerging Growth Company

We are an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that (i) we are no longer an emerging growth company or (ii) we affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

While our significant accounting policies are described in greater detail in Note 2, “Summary of Significant Accounting Policies,” to our consolidated financial statements, we believe that the following policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We generate revenue from seller marketplace services and other services. Seller marketplace services primarily consist of marketplace transactions, subscriptions, and listing fees. Other services consist of other charges to our sellers including advertising revenues generated from displaying ads on our online marketplace. Revenue is recognized as we transfer control of promised goods or services to customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Control is transferred when the buyer and seller have agreed to the sale. We do not obtain legal title to or control the goods being purchased. We evaluate whether it is appropriate to recognize revenue on a gross or net basis based upon our evaluation of whether we obtain control of the specified goods or services by considering if we are primarily responsible for fulfillment of the promise, have inventory risk, or have latitude in establishing pricing and selecting suppliers, among other factors.

Property and Equipment, net

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives. The general range of useful lives of property and equipment is as follows:


			Estimated Useful Life
Leasehold improvements			Lesser of lease term or life of asset
Furniture and fixtures			3 years
Computer equipment and software			3 years
Internal-use software			Lesser of contract term or 3 years

We capitalize costs related to internal-use software during the application development stage, including consulting costs and compensation expenses related to employees who devote time to the development projects. We record software development costs in property and equipment, net. Costs incurred in the preliminary stages of development activities and post implementation activities are expensed in the period incurred and are included in technology development in the consolidated statements of operations. We also capitalize costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Once the project is available for general release, capitalization ceases, and asset amortization begins. Capitalized costs associated with internal-use software are amortized on a straight-line basis over their estimated useful life, which is generally three years, and are included in cost of revenue in the consolidated statements of operations.

Stock-Based Compensation

We measure all stock-based awards granted to employees, directors, and non-employees based on the fair value on the date of the grant and recognize compensation expense for those awards over the requisite service period, which is generally the vesting period of the respective award. The fair value of restricted stock units is based on the closing price of our common stock on the grant date. We have not issued any stock options during the years ended December 31, 2024 or 2023; however, for stock options issued prior, the fair value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions, including the closing price of the Company's common stock on the grant date, expected stock price volatility, the expected term of the award, the risk-free interest rate for a period that approximates the expected term of the option, and our expected dividend yield. Expected volatility was calculated based on the implied volatilities from market comparisons of certain publicly traded companies and other factors. The expected option term was calculated based on the simplified method, which uses the midpoint between the vesting date and the contractual term, as we did not have sufficient historical data to develop an estimate based on participant behavior at the time of the latest stock option grant. The risk-free interest rate was based on the U.S. Treasury bond yield with an equivalent term. We have not paid dividends and have no foreseeable plans to pay dividends.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our business, including the effects of interest rate changes and foreign currency fluctuations. Information relating to quantitative and qualitative disclosures about these market risks are described below. At times, our cash balances with individual banking institutions are in excess of federally insured limits. We have not experienced any credit losses related to our cash, cash equivalents, and short-term investments balances.

Interest Rate Sensitivity

Interest rate risk relates to the loss we could incur in our cash portfolios due to a change in interest rates. As of December 31, 2024, we had cash, cash equivalents and short-term investments of $103.9 million. Our cash and cash equivalents consist primarily of demand and money market accounts, as well as available-for-sale debt securities with an original maturity of 90 days or less. Our short-term investments consist primarily of U.S. Government agency and Treasury securities, as well as commercial paper and corporate notes which have an original maturity greater than 90 days and are highly liquid in nature. Due to the nature of our cash, cash equivalents and short-term investments, we would expect a hypothetical 100 basis point increase or decrease in interest rates to result in an approximate increase or decrease of $0.7 million in our cash, cash equivalents and short-term investments. While these are our best estimates of the impact of the specified interest rate scenario, actual results could differ from those projected. The sensitivity analysis presented assumes interest rate changes are instantaneous, parallel shifts in the yield curve. In reality, interest rate changes of this magnitude are rarely instantaneous or parallel.

Our principal use of cash, cash equivalents and short-term investments is to fund our operations including platform development to support our strategic initiatives and anticipated share repurchases under the 2024 Stock Repurchase Program. The remainder of cash, cash equivalents and short-term investments are held for working capital purposes. We do not enter into investments for trading or speculative purposes.

Foreign Currency Risk

Our net revenue is primarily denominated in U.S. dollars, Euros, and British pounds, depending on the currency selection of the seller. Our cost of revenue and operating expenses are primarily denominated in U.S. dollars. As our online marketplace continues to grow globally, our results of operations and cash flows may be subject to fluctuations due to the change in foreign exchange rates. To date, fluctuations due to changes in the Euro and British pound have not been significant, but we may experience material foreign exchange gains and losses in our statement of operations in the future. As of December 31, 2024, we would expect an adverse 10% change in current exchange rates would result in no more than a $3.2 million decrease in net revenue for the year ended December 31, 2024.

Credit Risk

We are exposed to credit risk on accounts receivable balances. This risk is mitigated by requiring upfront payment for many of our services and due to our diverse customer base, dispersed over various geographic regions and industrial sectors. For the years ended December 31, 2024 and 2023, no single customer accounted for more than 10% of our net revenue. We maintain provisions for potential credit losses and such losses to date have been within our expectations. We evaluate the solvency of our customers on an ongoing basis to determine if additional allowances for doubtful accounts need to be recorded.

Inflation Risk

Our results of operations and financial condition are presented based on historical cost. While it is difficult to accurately measure the impact of inflation due to the imprecise nature of the estimates required, we believe certain metrics have been impacted, both directly and indirectly, by macroeconomic factors, including inflation and as a result significant capital market and housing market volatility. Additionally, if our costs were to become subject to inflationary pressures, we might not be able to fully offset such higher costs through net revenue and GMV increases. Our inability or failure to do so could harm our business, financial condition, and results of operations. We cannot assure you our business will not be affected in the future by inflation.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of 1stdibs.com, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of 1stdibs.com, Inc. (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2013.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.Description of the Business and Basis of Presentation

Description of the Business

1stdibs.com, Inc. (“1stDibs” or the “Company”) is one of the world’s leading online marketplaces for connecting design lovers with many of the best sellers and makers of vintage & antique furniture, contemporary furniture, home décor, jewelry, watches, art, and fashion. The Company’s sellers, who undergo an evaluation by its in-house experts to vet the integrity of their listings, in-depth marketing content, and custom-built technology platform create trust in the Company’s brand and facilitate high-consideration purchases of luxury design items online. By disrupting the way these items are bought and sold, 1stDibs is both expanding access to, and growing the market for, luxury design items.

The Company was incorporated in the state of Delaware on March 10, 2000 and is headquartered in New York, NY.

Basis of Presentation

The accompanying consolidated financial statements are prepared in accordance with the accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Certain immaterial amounts in the financial statements of the prior years have been reclassified to conform to the current year presentation for comparative purposes.

2.Summary of Significant Accounting Policies

Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, revenue recognition, provision for transaction losses, allowance for doubtful accounts, impairment assessment of goodwill, capitalization of internal-use software and the determination of useful lives, income taxes, and the valuation of stock-based compensation and leases. The Company evaluates its estimates and assumptions on an ongoing basis. Actual results could differ from those estimates and such differences may be material to the consolidated financial statements.

Foreign Currency and Currency Translation

The Company has determined that the functional currency for its foreign operations is the currency of the primary cash flow of the operation, which is generally the local currency in which the operation is located. All assets and liabilities are generally translated into U.S. dollars using exchange rates in effect at the balance sheet date. Income and expenses are translated at the average exchange rate in effect during the period. Unrealized translation gains and losses are recorded as a translation adjustment, which is included in the consolidated statements of stockholders’ equity as a component of accumulated other comprehensive loss. Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the local currency are included in other, net in the consolidated statements of operations.

Segment Information

An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision maker (the “CODM”). The Company operates and manages its business as one reportable and operating segment. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on a consolidated basis for purposes of evaluating financial performance and allocating resources. The Company’s single reportable and operating segment contains one reporting unit, which consists of the Company’s online marketplace that enables commerce between sellers and buyers. The CODM regularly reviews the GAAP consolidated statement of operations from a significant expense perspective when evaluating financial performance and allocating resources. While the CODM also reviews other funnel metrics regularly (GMV, Number of Orders, etc.), there are no additional significant segment expenses other than those disclosed in the consolidated statements of operations included within this section, Item 8. Financial Statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting. The Company measures the tangible and intangible identifiable assets acquired, liabilities assumed, any non-controlling interest in the acquiree, and contingent consideration at fair value as of the acquisition date. Any excess purchase price over the fair value of net assets acquired is recorded as goodwill. Measurement period adjustments, if any, to the preliminary estimated fair value of the intangibles assets as of the acquisition date are recorded in goodwill. The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of acquisition.

Acquisition-related expenses represent expenses incurred by the Company to effect a business combination, including expenses such as finder’s fees and advisory, legal, accounting, valuation, and other professional or consulting fees, and are not included as a component of consideration transferred, but are accounted for as an expense in the period in which the costs are incurred or the services are rendered.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents and short-term investments. Cash and cash equivalents are placed with large financial institutions that management believes are of high credit quality. At times, the Company’s cash balances with individual banking institutions are in excess of federally insured limits. The risk for short-term investments is mitigated by the high quality nature of the investments. The Company has not experienced any credit losses related to its cash, cash equivalents and short-term investments. As of December 31, 2024 and 2023, the Company had no single seller, who the Company considers its customers, that represented more than 10% of its net revenue.

Cash, Cash Equivalents, and Restricted Cash

The following represents the Company’s cash, cash equivalents, and restricted cash as of the periods presented:


	December 31,

Total cash, cash equivalents and restricted cash	$	29,621	$	40,975	$	158,043

The Company considers all short-term, highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Certain cash equivalents consist of investments in debt securities that are classified as available-for-sale. During the year ended December 31, 2024, the Company purchased $28.8 million of available-for-sale securities classified as cash equivalents. During the year ended December 31, 2023, the Company purchased $43.1 million of available-for-sale securities classified as cash equivalents, and there were no purchases of available-for-sale securities during the year ended December 31, 2022. As of December 31, 2024, the Company’s restricted cash relates to $3.7 million in Letters of Credit for its office leases in New York, New York. Additionally, $1.5 million was held in a joint escrow account in connection with the sale of 1stdibs Design Manager, Inc. (“Design Manager”) during the year ended December 31, 2022. During the year ended December 31, 2023, the restriction was lifted and the funds were released. The carrying value of the restricted cash approximates fair value.

Short-term Investments

Short-term investments designated as available-for-sale securities are carried at fair value, which is based on quoted market prices for such securities, if available, or is estimated on the basis of quoted market prices of financial instruments with similar characteristics. Investments with original maturities greater than 90 days and less than one year are classified within short-term investments on the Company’s consolidated balance sheets. In addition, investments with maturities beyond one year at the time of purchase that are highly liquid in nature and represent the investment of cash that is available for current operations are classified as short-term investments. Any other investments with original maturities greater than one year would be classified within long-term investments. Additionally, the Company records accrued interest receivable within other current assets on its consolidated balance sheets. Accrued interest receivable was $0.6 million and $0.5 million as of December 31, 2024 and December 31, 2023, respectively.

Unrealized gains and losses of available-for-sale securities are excluded from earnings and are reported as a component of other comprehensive income (loss) until the security is sold, has matured, or the Company determines that the fair value of the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

security has declined below its adjusted cost basis and the decline is not due to a credit loss. Realized gains and losses on short-term investments are calculated based on the specific identification method and are reclassified from accumulated other comprehensive loss to other, net in the Company’s consolidated statements of operations.

Short-term investments are evaluated for impairment quarterly. The Company’s portfolio of available-for-sale debt securities is required to incorporate forward-looking information to determine any credit losses. This risk is mitigated by the high quality nature of the investments. The Company evaluates the current expected credit loss by considering various factors in determining whether it should recognize an impairment charge, including the credit quality of the issuer, the duration that the fair value has been less than the adjusted cost basis, the severity and reason for the decline in value, and the Company’s intent to sell and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. If the Company concluded that an investment is impaired or a portion of the unrealized loss is a result of a credit loss, it recognizes the charge at that time in the consolidated statements of operations. Determining whether the decline in fair value is due to a credit loss requires management judgment based on the specific facts and circumstances of each security. The ultimate value realized on these securities is subject to market price volatility until they are sold. The Company did not recognize any credit losses related to available-for-sale debt securities during the years ended December 31, 2024 and 2023.

Accounts Receivable, net

The Company’s accounts receivable are recorded at amounts billed to sellers, generally for non-transactional revenue, which includes subscription, listing fees and advertising revenue, and are presented net of an estimated allowance for doubtful accounts on the Company’s consolidated balance sheets. The Company’s accounts receivable do not bear interest and do not require collateral or other security to support related receivables. The allowance for doubtful accounts considers forward-looking information to estimate expected credit losses using a number of factors, including age of the receivable, current economic conditions, historical losses, and management’s assessment and judgment of the sellers. The evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. Losses are charged against the allowance when management believes the uncollectibility of a receivable is confirmed and subsequent recoveries, if any, are credited to the allowance. Account balances are written off after all means of collection are exhausted and the potential for non-recovery is determined to be probable. Adjustments to the allowance for doubtful accounts are recorded as a component of provision for transaction losses in the consolidated statements of operations.

Receivables from Payment Processors and Payables Due to Sellers

Receivables from payment processors represent amounts received from buyers via third-party payment processors which

will be deposited by the payment processors to 1stDibs’ bank accounts for payment to sellers and shipping carriers. The Company also collects and remits sales tax from buyers on behalf of sellers in certain jurisdictions as a marketplace facilitator.

The portion of the cash and related receivable remaining after deducting the Company’s commission from its sellers and processing fees represents the total payables due to third parties, which consists of payables due to sellers, payables due to shipping carriers in instances where 1stDibs’ shipping services are elected by sellers, and payables due to tax authorities. The Company establishes an allowance for seller refunds for amounts that sellers owe the Company after a return is processed. The allowance for seller refunds was $0.1 million and $0.2 million at December 31, 2024 and 2023, respectively and included in other current assets on the Company’s consolidated balance sheets.

Property and Equipment, net

The Company capitalizes costs related to internal-use software during the application development stage, including consulting costs and compensation expenses related to employees who devote time to the development projects. The Company records software development costs in property and equipment, net. Costs incurred in the preliminary stages of development activities and post implementation activities are expensed in the period incurred and are included in technology development in the consolidated statements of operations. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Once the project is available for general release, capitalization ceases, and asset amortization begins. Capitalized costs associated with internal-use software are amortized on a straight-line basis over their estimated useful life, which is generally three years, and are included in cost of revenue in the consolidated statements of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The general range of useful lives of property and equipment is as follows:


			Estimated Useful Life
Leasehold improvements			Lesser of lease term or life of asset
Furniture and fixtures			3 years
Computer equipment and software			3 years
Internal-use software			Lesser of contract term or 3 years

When assets are sold or retired, the cost and related accumulated depreciation or amortization of assets disposed of are removed from the accounts, with any resulting gain or loss recorded in income from operations in the consolidated statements of operations and consolidated statements of comprehensive loss. Costs of repairs and maintenance are expensed as incurred.

When events occur or changes in circumstances require, the Company assesses the likelihood of recovering the cost of long-lived assets based on its expectations of future profitability, undiscounted cash flows, and management’s plans with respect to operations to determine if the asset is impaired and subject to write-off. Measurement of any impairment loss is based on the excess of the carrying value of the asset over the fair value. For the years ended December 31, 2024, 2023 and 2022, there were no impairment losses recorded.

Goodwill

Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s goodwill is evaluated at the entity level as it is determined there is one reporting unit, 1stDibs.

The Company performs its annual goodwill impairment test as of October 1st or more frequently if events or changes in circumstances indicate that the goodwill may be impaired. The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the Company determines it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then additional impairment testing is not required. However, if the Company concludes otherwise, then it is required to perform a quantitative assessment for impairment.

The quantitative assessment involves comparing the estimated fair value of the reporting unit with its respective book value, including goodwill. If the estimated fair value exceeds book value, goodwill is not impaired. If the book value of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to the excess, not to exceed the total amount of goodwill allocated to the reporting unit.

Based on the Company’s assessments, there were no impairment losses recorded during the years ended December 31, 2024, 2023 and 2022.

Leases

The Company enters into contracts in the normal course of business and assesses whether any such contracts contain a lease. The Company determines if an arrangement is a lease at inception if it conveys the right to control the identified asset for a period of time in exchange for consideration. The Company classifies leases as operating or financing in nature, and records the associated right-of-use asset and lease liability on its consolidated balance sheet. The lease liability represents the present value of future lease payments, net of lease incentives, discounted using an incremental borrowing rate, which is a management estimate based on the information available at the commencement date of a lease arrangement.

Lease expense is recognized as a single lease cost on a straight-line basis over the lease term. The lease term consists of non-cancelable periods and may include options, including those to extend or terminate, if it is reasonably certain they will be exercised. The Company accounts for lease and non-lease components related to operating leases as a single lease component. The Company has elected that costs associated with leases having an initial term of 12 months or less ("short-term leases") are recognized in the consolidated statement of operations on a straight-line basis over the lease term and are not recorded on the balance sheet. Variable lease expense is recognized as incurred and consists primarily of real estate taxes, utilities, and other office space related expenses.

Contingencies

The Company has certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range and no amount within the range is a better estimate, the minimum amount of the range is recorded as a liability on the Company’s consolidated balance sheets. The Company does not accrue for contingent losses that, in its judgment, are considered to be reasonably possible, but not probable.

Fair Value of Financial Instruments

Certain assets and liabilities are carried at fair value in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Valuation techniques used to measure fair value require the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

•Level 1—Quoted prices in active markets for identical assets or liabilities.

•Level 2—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies, and similar techniques.

Short-term investments and certain cash equivalents consist of investments in debt securities that are available-for-sale. The table below segregates all assets that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date:

There were no transfers between Level 1, Level 2 or Level 3 during the years ended December 31, 2024 and 2023. The Company’s cash equivalents and short-term investments for the periods presented were valued using quoted market prices or alternative pricing sources and models utilizing observable market inputs and were classified as Level 1 or Level 2, accordingly. As of December 31, 2024 and 2023, all other financial instruments not included in the table above were classified as Level 1.

Income Taxes

Income taxes are computed using the asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements. In estimating future tax consequences, the Company considers all expected future events other than enactment of changes in tax laws or rates. A valuation allowance is recorded, if necessary, to reduce net deferred tax assets to their realizable values if management does not believe it is more likely than not that the net deferred tax assets will be realized.

The Company follows the provisions of the authoritative guidance from the Financial Accounting Standards Board (“FASB”) on accounting for uncertainty in income taxes. For benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by the taxing authorities. The amount recognized is measured as the largest amount of benefit that has a greater than 50% likelihood of being realized upon ultimate audit settlement. The Company recognizes interest and penalties related to uncertain tax positions in the provision for income taxes. As of December 31, 2024 and 2023, the Company had no accrued interest or penalties related to uncertain tax positions.

The Company has made an accounting policy election to treat Global Intangible Low-Taxed Income taxes as a current period expense rather than including these amounts in the measurement of deferred taxes.

Net Loss per Share

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding for the period without consideration of potentially dilutive common stock. Diluted earnings per share is computed by dividing the diluted earnings by the weighted average number of common shares outstanding for the period, including potential dilutive common shares using the treasury stock method. For periods in which the Company reports net losses, diluted net loss per common share is the same as basic net loss per common share because including common stock equivalents would be anti-dilutive

Treasury Stock

In August 2024, the Board of Directors authorized the Company to repurchase up to an aggregate of $10.0 million of its common stock (“2024 Stock Repurchase Program”).

The repurchases may be affected, from time-to-time, through open market purchases, privately negotiated transactions, Rule 10b5-1 plans, accelerated stock repurchases, block trades, derivative contracts or otherwise in compliance with Rule 10b-18 of the Exchange Act. The repurchase programs are not subject to a termination or expiration date, and it does not obligate the Company to acquire any specific number of shares. The timing, price and volume of repurchases will be based on a number of factors, including market conditions, relevant securities laws, and other considerations.

The repurchased common stock is classified as treasury stock on the consolidated balance sheets. The direct costs incurred to acquire treasury stock are treated like stock issue costs and added to the cost of the treasury stock, which includes applicable fees and taxes. Repurchased common stock is stated at cost, determined on an average cost basis and is presented as a reduction of stockholders’ equity on the consolidated balance sheets.

Revenue Recognition

The Company’s net revenue consists principally of seller marketplace services. Seller marketplace services primarily consist of marketplace transactions, subscriptions, and listing fees. Revenue is recognized as the Company transfers control of promised goods or services to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Control is transferred when the buyer and seller have agreed to the sale. The Company does not obtain legal title to or control the goods being purchased. The Company evaluates whether it is appropriate to recognize revenue on a gross or net basis based upon its evaluation of whether the Company obtains control of the specified goods or services by considering if it is primarily responsible for fulfillment of the promise, has inventory risk, has the latitude in establishing pricing and selecting suppliers, among other factors. The Company does not have any remaining performance obligations associated with contracts with terms greater than one year.

Marketplace Transactions

The Company charges sellers commission and processing fees for successful purchases through its online marketplace. For the items purchased through the 1stDibs online marketplace, the Company collects the Gross Merchandise Value (“GMV”) from the buyer, and recognizes the associated revenue on a net basis, which equates to the commission and processing fees earned in exchange for the seller marketplace services. The commission fees range from 5% to 50% of GMV and processing fees, which are approximately 3% of the buyer’s total payment, net of expected refunds. If a seller accepts a return or refund of an on-platform purchase, the related commission and processing fees are refunded to the seller. The Company records discounts provided to the end buyer, to whom the Company has no performance obligation, such as promotional discounts, in sales and marketing expense since the discounts are not related directly to the Company’s revenue source but rather used as a marketing tool, and the seller is not made aware of the discounts provided to the end buyer. The commission and processing fees are recognized net of estimated refunds when the corresponding transaction is confirmed by the buyer and seller. The Company does not take title to inventory sold or assume risk of loss at any point in time during the transaction and is authorized to collect consideration from the buyer and remit net consideration to the seller to facilitate the processing of the confirmed purchase transaction.

Subscriptions

The Company offers its sellers various subscription pricing tiers which allows them to choose the plan that best fits their business, with choices of a higher monthly subscription fee and lower commission rates or a lower monthly subscription fee and higher commission rates. Sellers receive the benefit of marketplace activities, including listing items for sale, completing sales transactions, and payments processing, which represents a single stand-ready performance obligation. The Company has determined that its customers are sellers on its online marketplace since sellers pay for the use of the platform to sell their inventory. Subscription fees are calculated on an annual basis, payable and recognized monthly. If during the annual subscription period a seller ceases to make its monthly payment, the Company is no longer obligated to provide the subscribed services and the seller can be terminated at the Company’s sole discretion.

Listings

The Company earns listing fees from sellers on a per item basis as directed by the seller to promote certain items at the seller’s discretion. Listing fees are recognized ratably over time when the listing is publicly posted.

Advertisements

Advertising revenue is generated by displaying seller ads on the 1stDibs online marketplace. For advertising services, the Company enters into agreements with advertisers, or sellers, in the form of signed insertion orders, which specify the terms of services and fees, prior to advertising campaigns being run. The Company recognizes revenue from the display of impression-based ads in the period in which the impressions are delivered in accordance with the contractual terms of the insertion orders. Impressions are considered delivered when an ad is displayed to users.

Contract Costs

The Company capitalizes commission costs that are incremental and directly related to the acquisition of seller agreements. Commissions are earned by the Company’s sales force when the seller’s listings are publicly visible and available for purchase on the 1stDibs online marketplace. Commission costs are capitalized when earned and are amortized as expense over an estimated seller relationship period of three years. The Company determined the estimated seller relationship period by taking into consideration the contractual term of the seller agreements, the seller’s lifetime expected value, and the fact that no additional commission is paid for renewed seller agreements. The Company periodically reviews the costs to obtain revenue contracts to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these costs to obtain revenue contracts.

Contract Balances from Contracts with Customers

A contract liability is an obligation to transfer goods or services for which consideration has been received or is due to a customer. Contract liabilities consist of deferred revenue that is unearned related to advertising fees charged to sellers for which advertisements have not been delivered. Deferred revenue for advertising fees is recognized as revenue in the periods in which our performance obligations are satisfied. As of December 31, 2024 and 2023, deferred revenue was less than $0.1 million and $0.1 million, respectively.

Cost of Revenue

Cost of revenue includes payment processor fees, hosting expenses, and expenses associated with payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with personnel supporting revenue-related operations, amortization of internal-use software, and consulting costs.

In certain transactions where 1stDibs shipping and logistics services are elected by sellers, the Company enables shipping of items purchased from the seller to the buyer. Any difference between the amount collected for shipping and the amount charged by the shipping carrier is included in cost of revenue in the consolidated statements of operations.

Sales and Marketing

Sales and marketing expenses include payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with sales and marketing personnel, advertising expense, consulting costs, and promotional discounts offered to new and existing buyers. Advertising expenses consist primarily of costs incurred promoting and marketing the Company’s online marketplace, such as costs associated with acquiring new users through performance-based marketing, social media, email, and events. Promotional discounts and incentives represent incentives solely to end buyers and, therefore, are not considered payments made to the Company’s customers. Buyers are not customers because access to the 1stDibs online marketplace is free for buyers and the Company has no performance obligations with respect to buyers.

The Company expenses all advertising expenses as incurred. During the years ended December 31, 2024, 2023, and 2022, the Company incurred advertising expenses of approximately $13.5 million, $11.0 million, and $16.3 million, respectively.

Technology Development

Technology development expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with engineering and product development personnel and consulting costs related to technology development. The Company expenses all technology development expenses as incurred. Expenses that meet the criteria for capitalization as internal-use software are capitalized to property and equipment, net on the consolidated balance sheets and amortized over their useful life. This amortization expense related to internal-use software is included in cost of revenue in the consolidated statements of operations.

General and Administrative

General and administrative expenses include payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with finance, legal, facility and human resources related personnel, lease expense, net of sublease income, business liability insurance, accounting, professional fees, and depreciation and amortization of property and equipment. The Company expenses all general and administrative expenses as incurred.

Provision for Transaction Losses

Provision for transaction losses consists primarily of losses resulting from the Company’s buyer protection program, including damages to products caused by shipping and transit, items that were not received or not as represented by the seller, and reimbursements to buyers at the Company’s discretion if they are dissatisfied with their experience. The provision for transaction losses also includes bad debt expense associated with the Company’s accounts receivable.

Restructuring Charges

In September 2022, the Company announced and implemented a restructuring plan to reduce operational costs and realign investment priorities involving the reduction of approximately 10% of the Company’s workforce. As a result of the reduction, the Company incurred approximately $0.7 million in restructuring charges, consisting primarily of employee severance and benefits costs.

In June 2023, the Company announced a workforce reduction designed to further reduce operating costs and further realign investment priorities involving the reduction of approximately 20% of the Company’s global workforce. As a result of the reduction, the Company incurred approximately $2.0 million in restructuring charges during the year ended December 31, 2023, consisting primarily of employee severance and benefits costs.

During the year ended December 31, 2024, the Company incurred $1.4 million of additional employee severance and benefits costs relating to a further workforce reduction. The majority of the $1.3 million of severance accrued as of December 31, 2024 is anticipated to be paid during the year ending December 31, 2025, while approximately $0.1 million is expected to be paid during the first quarter of 2026.

The following table displays a rollforward of the charges to the accrued balance as of December 31, 2024:

Stock-Based Compensation

The Company measures all stock-based awards granted to employees, directors, and non-employees based on the fair value on the date of the grant and recognizes compensation expense for those awards over the requisite service period, which is generally the vesting period of the respective award. The Company recognizes forfeitures as they occur. The fair value of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

restricted stock units is based on the closing price of the Company's common stock on the grant date. The Company has not issued any stock options during the years ended December 31, 2024 or 2023; however, for stock options issued prior, the fair value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model, which required inputs based on certain subjective assumptions, including the closing price of the Company's common stock on the grant date, expected stock price volatility, the expected term of the award, the risk-free interest rate for a period that approximated the expected term of the option, and the Company’s expected dividend yield. Expected volatility was calculated based on the implied volatilities from market comparisons of certain publicly traded companies and other factors. The expected option term was calculated based on the simplified method based on options that had been granted to date, which used the midpoint between the vesting date and the contractual term, as the Company at the time of the last option grant did not have sufficient historical data to develop an estimate based on participant behavior. The risk-free interest rate was based on the U.S. Treasury bond yield with an equivalent term. The Company has not paid dividends and has no foreseeable plans to pay dividends.

The Company classifies stock-based compensation expense in its consolidated statements of operations in the same manner in which the award recipient’s payroll costs or service payments are classified.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB under its ASC or other standard setting bodies. The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The Company adopted the standard effective for the year ended December 31, 2024, its impact was not material for its consolidated financial statements or related disclosures, updates to the disclosure are included within this Note 2, “Summary of Significant Accounting Policies.”

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures. The standard will require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The new standard is effective for annual periods beginning after December 15, 2024. The Company expects the adoption of the standard will require additional disclosures, but will not have a financial impact on the Company’s consolidated balance sheets and statement of operations.

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard was issued to improve disclosures regarding the types of expenses included in commonly presented expense captions. The new standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

2011 Option Plan

The Company adopted the 2011 Stock Option and Grant Plan (the “2011 Plan”) on September 2, 2011 and amended and restated the plan on December 14, 2011. The 2011 Plan provided for the Company to grant incentive stock options (“ISOs”), or non-qualified stock options, restricted stock awards, and other stock-based awards to its employees, directors, officers, outside advisors, and non-employee consultants. At the time of grant, the options issued to new employees pursuant to the 2011 Plan expire ten years from the date of grant and generally vest over four years, with 25% vesting on the first anniversary and the balance vesting ratably over the remaining 36 months. Options issued pursuant to the 2011 Plan expire ten years from the date of grant and generally vest ratably over 48 months.

The 2011 Plan was administered by the Compensation Committee of the Board. The exercise prices, vesting, and other restrictions were determined at the discretion of Compensation Committee of the Board.

Following the completion of the Company’s IPO in June 2021, no additional awards and no shares of the Company’s common stock remain available for future issuance under the 2011 Plan. However, the 2011 Plan will continue to govern the terms and conditions of the outstanding awards previously granted thereunder.

2021 Stock Incentive Plan

In May 2021, the Company's Board adopted, and its stockholders approved, the 2021 Stock Incentive Plan (the “2021 Plan”), which became effective upon the SEC declaring the Company’s IPO registration statement effective. The 2021 Plan provides for the grant of ISOs, non-statutory stock options, restricted share awards, restricted stock unit awards (“RSUs”), stock appreciation rights, cash-based awards, and performance-based stock awards, or collectively, stock awards. ISOs may be granted only to the Company’s employees, including officers, and the employees of its parent or subsidiaries. All other stock awards may be granted to the Company’s employees, officers, non-employee directors, consultants, and the employees and consultants of its parent, subsidiaries, and affiliates. Depending on the nature of the award granted, the vesting terms may differ. Generally for new hire awards, the requisite service period for RSUs to vest is over four years from the grant date, with 25% vesting on the first anniversary and the balance vesting ratably on a quarterly basis over the remaining vesting period. Generally, all additional RSUs vest ratably on a quarterly basis over three or four years beginning on the three month anniversary from the grant date. For RSU grants to members of our Board of Directors, initial awards vest ratably on an annual basis over three years, and over one year for our Board of Directors annual awards.

The aggregate number of shares of the Company’s common stock that may be issued pursuant to stock awards under the 2021 Plan will not exceed the sum of (x) 4,333,333 shares (as adjusted for stock splits, stock dividends, combinations, and the like), plus (y) the sum of (1) the number of reserved shares not issued or subject to outstanding awards under the 2011 Plan on the effective date of the 2021 Plan and (2) the number of shares subject to outstanding stock awards granted under the 2011 Plan and that, following the effective date of the 2021 Plan, (A) are subsequently forfeited or terminated for any reason before being exercised or settled, (B) are not issued because such stock award is settled in cash, (C) are subject to vesting restrictions and are subsequently forfeited, (D) are withheld or reacquired to satisfy the applicable exercise, strike, or purchase price, or (E) are withheld or reacquired to satisfy a tax withholding obligation, plus (z) an annual increase on the first day of each fiscal year, for a period of not more than 10 years, beginning on January 1, 2022 and ending on, and including, January 1, 2031, in an amount equal to the lesser of (i) 5% of the outstanding shares on the last day of the immediately preceding fiscal year or (ii) such lesser amount that the Compensation Committee of the Board determines for purposes of the annual increase for that fiscal year. On January 1, 2024, the number of shares of common stock available for issuance under the 2021 Plan was automatically increased according to its terms by 1,995,756 shares.

As of December 31, 2024, 2,238,376 shares were available for future grants of the Company’s common stock.

Employee Stock Purchase Plan

In May 2021, the Company's Board adopted, and its stockholders approved, the Company's 2021 Employee Stock Purchase Plan (the "ESPP"). A total of 1,971,655 shares of the Company's authorized but unissued or reacquired shares of its common stock (as adjusted for stock splits, stock dividends, combinations, and the like) are available for issuance under the ESPP. The number of shares of the Company's common stock that will be available for issuance under the ESPP also includes an annual increase on the first day of each fiscal year, for a period of not more than 10 years, beginning on January 1, 2022, equal to the least of: (i) 1% of the outstanding shares of the Company’s common stock on such date, (ii) 400,000 shares (as adjusted for stock splits, stock dividends, combinations, and the like) or (iii) a lesser amount determined by the Compensation Committee or the Company’s Board of Directors. On January 1, 2024, the number of shares of common stock available for issuance under the ESPP was automatically increased according to its terms by 399,151 shares.

During regularly scheduled “offerings” under the ESPP, participants may purchase the Company’s common stock through payroll deductions, up to a maximum of 15% of their eligible compensation, or such lower limit as may be determined by the Compensation Committee from time to time. Participants will be able to withdraw their accumulated payroll deductions prior to the end of the offering period in accordance with the terms of the offering. Participation in the ESPP will end automatically on termination of employment. The purchase price will be specified pursuant to the offering, but cannot, under the terms of the ESPP, be less than 85% of the fair market value per share of the Company’s common stock on either the offering date or on the purchase date, whichever is less. The fair market value of the Company’s common stock for this purpose will generally be the closing price on the Nasdaq Global Market (or such other exchange as the Company’s common stock may be traded at the relevant time) for the date in question, or if such date is not a trading day, for the last trading day before the date in question. As of December 31, 2024, an initial offering period has not commenced, and for the year ended December 31, 2024, no shares of common stock were purchased under the ESPP.

The reconciliation of the U.S. federal statutory rate to the Company’s effective rate is as follows:


	Year Ended December 31,
	2024	2023	2022
Income tax benefit using U.S. federal statutory rate	21.0%	21.0%	21.0%

When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.3)% for the year ended December 31, 2024 was due primarily to the changes in valuation allowance, changes in uncertain tax positions, executive compensation, and non-deductible expenses.

When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.1)% for the year ended December 31, 2023 was due primarily to the changes in valuation allowance, state taxes, and stock compensation.

When compared to the U.S. statutory tax rate of 21.0%, the effective rate of (0.2)% for the year ended December 31, 2022 was due primarily to the changes in valuation allowance, state taxes, and Sale of Design Manager.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. The significant components of the Company’s deferred income tax assets and liabilities at December 31, 2024 and 2023 were comprised of the following:


	Year Ended December 31,
(in thousands)	2024		2023
Deferred tax assets
Net operating losses	$	34,277	$	31,710
Research credits	769		3,092
Property and equipment	323		363
Intangible assets and goodwill	864		1,074

Net deferred tax liabilities	$	—	$	—

A valuation allowance is required to be established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company considered all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, loss carryback and tax-planning strategies in assessing the need for a valuation allowance. As of December 31, 2024 and 2023, the Company believe it is more likely than not that the net deferred tax assets will not be realizable. Accordingly, the Company has applied a valuation allowance against its net deferred tax assets. The net change in the total valuation allowance for the years ended December 31, 2024 and 2023 was a decrease of approximately $0.8 million and increase of approximately $4.9 million, respectively.

The activity in the Company’s valuation allowance for the years ended December 31, 2024 and 2023, was as follows:


	Year Ended December 31,
(in thousands)	2024		2023
Valuation allowance at beginning of year	$	49,814	$	44,951
(Decrease) Increases recorded to provision for income taxes	(825)		4,887
Decreases recorded to equity	(11)		(24)
Valuation allowance at end of year	$	48,978	$	49,814

At December 31, 2024, the Company had approximately $123.0 million and $128.5 million of federal and state net operating loss (“NOL”) carryforwards, respectively. Approximately $52.6 million of the federal NOL and $81.4 million of the state NOL was generated prior to the 2018 tax year. As a result, these net operating loss carryforwards will expire, if not utilized, between 2031 and 2037 for federal and state income tax purposes. The post 2017 NOLs are subject to an indefinite carryforward period; therefore, $70.4 million of federal NOLs generated after 2017 may be carried forward indefinitely. As it pertains to the approximately $47.1 million of state NOLs generated after 2017, not all states have conformed to the Tax Cuts and Jobs Act of 2017; therefore, some state’s NOLs are unlimited while some will expire based on the respective state. The Company also has federal and state tax credits relating to research and development credits of $4.9 million and less than $0.1 million, which begin to expire in 2031.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The utilization of NOLs and tax credit carryforwards to offset future taxable income may be subject to an annual limitation as a result of ownership changes that have occurred previously or may occur in the future. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (“IRC”), a corporation that undergoes an ownership change may be subject to limitations on its ability to utilize its pre-change NOLs and other tax attributes otherwise available to offset future taxable income and/or tax liability. An ownership change is defined as a cumulative change of 50% or more in the ownership positions of certain stockholders during a rolling three-year period. The Company completed formal studies through December 31, 2022 to determine if any ownership changes within the meaning of IRC Section 382 and 383 have occurred. As a result of the studies, the Company determined that although it experienced an ownership change on July 28, 2015, the limitation from the ownership change will not result in any of the NOLs or tax credits expiring unutilized. No additional ownership changes have occurred through the date of the most recent study. The Company is in the process of updating the formal study through December 31, 2024 to determine if any ownership changes within the meaning of IRC Section 382 and 383 have occurred.

The Company assesses foreign investment levels periodically to determine if all or a portion of the Company’s investments in its foreign subsidiary are indefinitely invested. The Company’s current intention is to permanently reinvest undistributed earnings of our foreign subsidiary. Any required adjustment to the income tax provision would be reflected in the period that the Company changes this assessment.

As of December 31, 2024 and 2023, the Company had unrecognized tax benefits of $4.1 million and $1.0 million, respectively, which, if recognized, would not impact the Company’s tax provision and effective income tax rate due to a full valuation allowance. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision. As of December 31, 2024 and 2023, the Company had not accrued interest or penalties related to unrecognized tax benefits. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:


	Year Ended December 31,
(in thousands)	2024		2023
Gross tax contingencies as of beginning of year	$	1,031	$	1,022
Additions for tax positions related to the current year	84		9
Additions for tax positions of prior years	2,976		—
Gross tax contingencies as of end of year	$	4,091	$	1,031

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, foreign jurisdictions, and various state and local jurisdictions. The Company’s federal and state tax returns for the tax years ended December 31, 2020 and forward generally remain subject to examination from the Internal Revenue Service and state tax authorities. However, the federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period outside the statutes of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statutes of limitations. Therefore, the Company’s tax years generally remain open to examination for all federal and state income tax matters until its net operating loss carryforwards are utilized and the respective statutes of limitations have lapsed. The returns in U.S. and state jurisdictions have varying statutes of limitations.

The Company’s income tax returns for December 31, 2020 through December 31, 2024 for their foreign subsidiaries remain subject to examination by tax authorities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company’s potentially dilutive securities, which include outstanding stock options and restricted stock units have been excluded from the computation of diluted net loss per share from each period as including them would have had an anti-dilutive effect. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potentially dilutive securities for each period presented:


	Year Ended December 31,
	2024	2023	2022
Options to purchase common stock	3,560,144	3,831,710	4,034,287

Total	7,790,320	7,232,199	6,842,268

16.Commitments and Contingencies

Contractual Obligations

The Company has $29.2 million of non-cancelable contractual commitments as of December 31, 2024, primarily related to its operating lease agreements for both its current and former corporate headquarters in New York, NY, not including any offset for sublease income, as well as other software and support services. For those agreements with variable terms, the Company does not estimate what the total obligation may be beyond any minimum obligations. The following table represents the Company’s commitments under its purchase obligations as of December 31, 2024 (in thousands):


Fiscal Year Ending December 31,	Lease Obligations		Other Obligations		Total Obligations
2025	$	5,379	$	1,658	$	7,037

2029	4,292		—		4,292
Total	$	25,460	$	3,716	$	29,176

Legal Proceedings

The Company is subject to various claims and contingencies which are in the scope of ordinary and routine litigation incidental to its business, including those related to regulation, litigation, business transactions, employee-related matters, and taxes, among others. When the Company becomes aware of a claim or potential claim, the likelihood of any loss or exposure is assessed. If it is probable that a loss will result and the amount of the loss can be reasonably estimated, the Company records a liability for the loss. The liability recorded includes probable and estimable legal costs incurred to date and future legal costs to the point in the legal matter where the Company believes a conclusion to the matter will be reached. If the loss is not probable or the amount of the loss cannot be reasonably estimated, the Company discloses the claim if the likelihood of a potential loss is reasonably possible. The Company does not believe that it is party to any pending legal proceedings that are likely to have a material effect on its business, financial condition or results of operations for the years ended December 31, 2024 and 2023.

Indemnification

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its Board and officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications.

Sales and other indirect tax contingencies

The Company conducts operations in many tax jurisdictions for which indirect taxes, such as sales, use and other indirect taxes, are assessed on its operations. Although the Company is diligent in collecting and remitting such taxes, there is uncertainty as to what constitutes sufficient presence or responsibility for a jurisdiction to levy taxes, fees, and surcharges for sales made on an e-commerce platform. The Company recognized liabilities for contingencies related to sales and indirect taxes

deemed probable and estimable totaling $1.1 million and $2.5 million as of December 31, 2024 and 2023, respectively, which are included in other current liabilities in the Company’s consolidated balance sheets.

17.401(K) Savings Plans

For the Company’s United States employees, it maintains a defined contribution savings plan under Section 401(k) of the Internal Revenue Code, which is offered to all eligible employees, and participants may make voluntary contributions. Company contributions to the plan may be made at the discretion of the Company’s board of directors. These contributions to date have been immaterial. The Company also has various pension plans for its non-U.S. employees, some of which are required by local laws, and allow or require employer contributions. These plans cover substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosures

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2024. “Disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2024 at the reasonable assurance level.

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

Management’s Report on Internal Controls Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our management, including our Chief Executive Officer and our Chief Financial Officer, conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment, our management has concluded that our internal control over financial reporting was effective as of December 31, 2024 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP.

Additionally, our auditors are not required to opine on the effectiveness of our internal control over financial reporting pursuant to Section 404 as we are considered an “emerging growth company” as defined in the JOBS Act.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified during the three months ended December 31, 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and our Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by the collusion of two or more people or by management override of controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Item 9B. Other Information

Rule 10b5-1 Trading Arrangements

During the quarter ended December 31, 2024, the following officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted a Rule 10b5-1 trading arrangement, as defined in Item 408 of Regulation S-K, for the sale of our common stock. Shares in each 10b5-1 trading arrangement that are subject to restricted stock units and stock options may only be traded following satisfaction of applicable vesting requirements. In addition, because of pricing (such as future share price targets) and timing conditions in each 10b5-1 trading arrangement, it is not yet determinable how many shares actually will be sold under each plan prior to its expiration date.

On December 14, 2024, Nancy Hood, our Chief Marketing Officer, entered into a 10b5-1 trading plan during an open insider trading window, intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act and the Company’s policies regarding insider transactions for trades over a period of time from March 14, 2025 until December 12, 2025 or such earlier time as when 124,382 shares of the Company’s common stock are sold.

On December 16, 2024, Ryan Beauchamp, our Chief Product Officer, entered into a 10b5-1 trading plan during an open insider trading window, intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act and the Company’s policies regarding insider transactions for trades over a period of time from June 9, 2025 until June 30, 2025 or such earlier time as when 10,856 shares of the Company’s common stock are sold.

During the quarter ended December 31, 2024, no other directors or officers adopted, modified, or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement,” as defined in Item 408 of Regulation S-K.

Offer of Employment by 1stdibs.com, Inc.

Dear Ryan,

On behalf of 1stdibs.com, Inc. (the “Company”), I am pleased to offer you the position of Chief Product Officer reporting to the Chief Executive Officer (“CEO”), David Rosenblatt. We believe that each person here will contribute directly to the growth and success of the company and we look forward to having you as a member of our team.

Start Date. Your employment will commence on March 27, 2023 (the “Start Date”).

Location. Your primary work location will be your home office in New York, in accordance with the Company’s Flexibility First and

remote work policies in effect at the time. You understand that the Company may require that you otherwise report to a Company

office as may be necessary to fulfill your responsibilities.

Base Salary. You will receive a bi-weekly base salary of $12,692.30, for an annual equivalent of $330,000 (the “Base Salary”), payable according to the Company’s usual payroll practices, less applicable withholding and taxes as required by law. Your annual salary will be prorated as necessary to reflect the actual days of employment completed by you during the first calendar year of your employment. This is a full-time, exempt position, meaning you will not be eligible for overtime compensation.

Executive Bonus. You will be eligible for an annual target bonus of $150,00.00, less applicable withholding and taxes as required by law, in accordance with, and subject to the terms and condition of, the annual performance bonus plan established by the Company from time to time for similarly situated employees. Any such bonus will be based on the achievement of goals and milestones established by the Company in its sole discretion, and the Company in its sole discretion may amend or terminate any such bonus plan at any time. Your annual bonus for 2023 will be prorated as necessary to reflect the actual days of employment completed by you during the first calendar year of your employment. To be eligible for any annual bonus you must be employed in good standing with the Company and not under notice of resignation or termination on the date any such bonus is due to be paid.

Equity Incentive. Subject to approval by the Compensation Committee (the “Committee”) of the Board of Directors of the Company, you will be granted an award of restricted stock units (“RSUs”) with respect to 220,000 shares of Company common stock (subject to appropriate adjustment for any stock split, stock dividend, combination or other recapitalization or reclassification). Your RSU award will be subject to the terms and conditions of the 1stdibs.com, Inc. 2021 Stock Incentive Plan and a restricted stock unit agreement, which you will receive after the Committee’s approval of your award. Subject to your continued employment with the Company, twenty-five percent (25%) of the RSUs will vest (or convert into shares of Company common stock) twelve (12) months after the first RSU vesting date following your Start Date. The balance of your RSUs will vest in equal quarterly installments over the next three years of continuous employment with the Company.

Moving forward, you will be eligible to participate in any executive compensation programs or plans approved by the Board, including without limitation annual equity grant awards that management of the Company intends to recommend to the Board in keeping with historical practice. Although management will recommend to the Board that you be granted the RSUs described above and intends to recommend annual equity grants for you commencing in 2024, by execution of this letter, you acknowledge that you have no right to receive the RSUs unless the grant is approved by the Board.

Signing Bonus. If you accept this employment offer, you will receive a cash signing bonus in an amount of $100,000 (the “Signing Bonus”), less applicable withholding and taxes as required by law. The Signing Bonus will be paid in one lump sum no later than 30 days from your start date in a payment separate from your salary payment of the same date. In the event that you resign or are terminated for Cause (as defined below) within 24 months of your Start Date, you will be required to repay 100% of the Signing Bonus to the Company within 30 days of your termination or resignation date; if you resign or are terminated for Cause between 12 months and 24 months after your Start Date, you will be required to repay 50% of the Signing Bonus to the Company within 30 days of your termination or resignation date. If you are terminated without Cause, you will not be required to repay any amount of the Signing Bonus.

Cause. For purposes of this offer letter, “Cause” shall include: (i) a material breach by you of your employment agreement or similar agreement with the Company;

(ii) a material violation by you of a federal or state law or regulation applicable to the business of the Company that has a material adverse effect on the Company;

(iii) your misappropriation or embezzlement of Company funds or property or an act of fraud upon the Company made by you;

(iv) your conviction of, or plea of guilty or nolo contendere to, a crime constituting a felony, or crime constituting a misdemeanor involving theft, embezzlement, dishonesty, or moral turpitude;

(v) the willful failure by you to perform your material duties for the Company;

(vi) repeated and continuous failure to perform your duties to the satisfaction of the Board in its good faith determination;

(vii) your breach of your fiduciary duties to the Company;

(viii) a willful violation of a written Company policy, the violation of which is stated in such policy to be grounds for termination, or lawful directive of the Board;

(ix) conduct which violates applicable law or the policies of the Company with respect to non-discrimination, workplace harassment or similar protections of workers in the workplace;

(x) an act by you which constitutes gross misconduct and which is materially and demonstrably injurious to the Company; or

(xi) your commission of any act, occurring or coming to light during your employment with the Company, that brings you into public contempt or ridicule or that the CEO and the Board reasonably judge to be likely to injure the operations or reputation of the Company or the Company’s employees or reputation, with you accorded an opportunity to respond in writing or in person, at your option, to the CEO and the Board prior to the termination of employment.

No act, or failure to act, by you shall be considered “willful” unless committed without good faith and without a reasonable belief that the act or omission was in the Company’s best interests.

Notwithstanding the foregoing, Cause shall not exist with respect to subsections (iv), (v), (vi) (vii) above until and unless you fail to cure such breach, neglect or misconduct (if such breach, neglect or misconduct is capable of cure) within ten (10) days after written notice from the Board. If your employment ends for any reason other than discharge by the Company for Cause, but at a time when the Company had Cause to terminate your employment (or would have had Cause if it knew all of the relevant facts), your termination shall be treated as a discharge by the Company for Cause.

Benefits Plans. Your eligibility begins on the 1st day of the month following your Start Date, or on the 1st day of the month coinciding with your Start Date if your Start Date is the 1st of the month. The Company reserves the right to modify, suspend or terminate the plans, at its sole discretion.

Paid Time Off (PTO). You are eligible to take part in the Company’s Paid Time Off (PTO) policy, which currently permits flexible time off. All PTO requests require prior approval from your supervisor and are subject to the terms and conditions of the policy. The Company reserves the right to modify, suspend or terminate the policy, as its sole discretion. You will be given further information about the Company’s PTO policy once your employment begins.

Confidentiality Agreement. As an employee of the Company, you will have access to certain confidential information and materials of the Company and you may, during the course of your employment, develop certain information, which shall be the property of the Company. To protect the Company’s interests, your employment is contingent upon your signing the Company’s “Employee Assignment of Intellectual Property, Confidentiality, and Non-Competition Agreement” (the “Confidentiality Agreement”) which is enclosed herewith.

You hereby represent and warrant to the Company that you (i) are not subject to any written non-solicitation, non-competition or any other agreement which might affect or limit your employment with the Company, (ii) are not subject to any written confidentiality or non-use/non-disclosure agreement affecting your employment with the Company, and (iii) have not brought and will not bring to the Company any trade secrets, confidential business information, documents, or other personal property of a prior employer.

Company Policies. If you accept this offer of employment, you acknowledge that you will have read and understand the Company’s policies already made available to you, and any other rules as may be set forth in writing and provided to you. You agree to abide by those policies and rules and any subsequent changes as set forth in writing from time to time by the Company and to abide by any confidentiality restrictions that the Company may require of you. You further agree not to obligate the Company to any contractual agreement or undertaking without the express approval of David Rosenblatt, CEO.

“At Will” Employment. Your employment with the Company is “at will.” This means that you may terminate your employment with the Company at any time, with or without notice or cause. The Company similarly may terminate your employment at any time, with or without notice or cause. Additionally, the Company may alter the terms and conditions of your employment at any time, with or without cause. Your participation in any benefit program shall not be regarded as assuring employment for any particular period of time, and no statement, representation, or conduct of any person or entity may alter the at will nature of your employment with the Company unless such statement is set forth in writing and signed by the Company’s CEO or Chief People Officer. The Company also reserves the right to modify or change your compensation and benefits at any time for any reason, among other factors, change of your work location.

Immigration Compliance. Your employment is also contingent upon your presenting documentation demonstrating that you have authorization to work in the United States within three (3) business days after commencing employment with the Company.

This letter sets forth the entire agreement between you and the Company and supersedes any and all prior or contemporaneous agreements or understandings, written or oral, pertaining to your employment with the Company. You acknowledge that you have

not relied upon any representations (oral or otherwise) other than those explicitly stated in this offer letter. Additionally, this letter cannot be changed or modified except by a separate writing signed by you and a duly authorized officer of the Company. All disputes concerning the application, interpretation or enforcement of this offer letter or otherwise arising out of the relationship between you, on the one hand, and the Company on the other hand shall be resolved exclusively by final and binding arbitration before a single arbitrator in accordance with the Employment Rules of the American Arbitration Association then in effect. The arbitration shall be held in New York City, NY and the arbitrator shall have the authority to permit the parties to engage in reasonable pre-hearing discovery.

This offer and your subsequent start date are contingent upon successful completion of a criminal background check.

Exhibit 19.1

1STDIBS.COM, INC.

INSIDER TRADING POLICY

Policy as to Trades in the Company’s Securities By Company Personnel

1.Purpose.

Both the Securities and Exchange Commission (the “SEC”) and Congress are very concerned about maintaining the fairness and integrity of the U.S. capital markets. The securities laws are continually reviewed and amended to prevent people from taking advantage of “inside information” and to increase the punishment for those who do. These laws require publicly-traded companies to have clear policies on insider trading. If companies like ours do not take active steps to adopt preventive policies and procedures covering securities trades by company personnel, the consequences could be severe.

We have adopted this Insider Trading Policy to avoid even the appearance of improper conduct on the part of anyone employed by or associated with 1stdibs.com, Inc. and its subsidiaries and branches (collectively, the “Company”) (not just so-called insiders). We have all worked hard to establish our reputation for integrity and ethical conduct. We cannot afford to damage this reputation.

2.Applicability.

This policy applies to all employees, officers, members of the Board of Directors, consultants and contractors of the Company or any subsidiary of the Company (the “Individuals”). This policy also applies to family members, other members of a person’s household and entities controlled by a person covered by this policy, as described below. This policy applies to all trading or other transactions in the Company’s securities, including common stock, options to purchase common stock and restricted stock units and any other securities that the Company may issue, such as preferred stock, notes, bonds and convertible securities, as well as to derivative securities relating to any of the Company’s securities, whether or not issued by the Company.

3.The Consequences.

The consequences of insider trading violations can be substantial:

For Individuals or Family Members who trade on inside information (or tip information to others):

•jail term of up to 20 years (30 years in certain circumstances);

•civil penalty of up to three times the profit gained or loss avoided; and

•criminal fine (no matter how small the profit) of up to $5 million.

For a company (as well as possibly any supervisory person) that fails to take appropriate steps to prevent illegal trading:

•civil penalty of the greater of $1 million or three times the profit gained or loss avoided as a result of the Individual’s violation; and

•criminal penalty of up to $25 million.

In addition, plaintiffs may claim that Individuals, Family Members, Controlled Entities or the Company are also liable to contemporaneous traders.

Further, if the Company has a reasonable basis to conclude that an employee has violated the Company’s Insider Trading Policy, whether or not knowingly, the Company may impose sanctions, including dismissal for cause. Needless to say, any of the above consequences, even an SEC investigation that does not result in prosecution, can tarnish one’s reputation (as well as the Company’s) and irreparably damage a career. Finally, the size of a transaction has no impact on potential insider trading liability. In the past, even relatively small trades (e.g., trades as small as $400) have resulted in SEC investigations and lawsuits.

4.Our Policy.

No Trading When in Possession of Material Non-Public Information. If a member of the Board of Directors, officer, any employee, consultant or contractor of the Company or any subsidiary of the Company has possession of material non-public information (often referred to as “inside information”) relating to our Company or any other company as to which the person receives information not available to investors generally, it is our policy that neither that person nor any of their Family Members or Controlled Entities (each as defined below) may buy or sell securities of the Company, make a gift of Company securities, or engage in any other action to take advantage of, or pass on to others, that information. In addition, no one who, in the course of rendering services to the Company or any subsidiary of the Company, learns of material non-public information relating to any other company (including our customers, suppliers, or partners) may (a) trade in such other company’s securities, (b) disclose material non-public information about such other company to anyone, (c) trade in the securities of an entity other than such other company based upon material non-public information about such other company or about the Company (i.e., “shadow trading”), or (d) give anyone trading advice about such other company, in each case until such information becomes public or is no longer material.

Transactions that may be necessary or justifiable for independent reasons (such as the need to raise money for an emergency expenditure) are no exception. Even the appearance of an improper transaction must be avoided to preserve our reputation for adhering to the highest standards of conduct.

What is Material Information? “Material information” is any information that a reasonable investor would consider important in deciding whether to buy, hold or sell securities of the Company or any securities of any other company as to which the person receives information not available to investors generally. In short, “material information” includes any information that reasonably could affect the price of our securities or any other securities. Either positive or negative information may be material. For example, it can be information about the Company or about a company with which we do business or compete.

Examples: Common examples of information that will frequently be regarded as material are:

earnings information and financial and operating results, projections of future earnings, losses or other business activity;

news of a possible merger, acquisition or tender offer;

news of a possible agreement, collaboration or partnership;

significant new products or services or delays in new product or service introduction or development;

plans to raise additional capital through stock sales or otherwise;

gain or loss of a significant partner or customer;

discoveries, or grants or allowances or disallowances of patents;

changes in management;

news of a significant sale of assets;

impending bankruptcy, restructuring or financial liquidity problems;

changes in dividend policies or the declaration of a stock split or stock repurchase plan;

pending or threatened litigation or regulatory proceedings, or their resolution;

regulatory approvals or changes that may materially impact the Company;

bank borrowings or other financing transactions out of the ordinary course;

changes in auditors or a determination that the Company’s financial statements can no longer be relied upon; and

significant cybersecurity incidents.

What is Non-Public Information? Information is “non-public” if it has not been disseminated in a manner making it available to investors generally, which typically entails broad dissemination through a press release to national wire services or a filing with the SEC. Speeches, television or radio appearances, magazine articles and website postings do not always suffice to render information public. The SEC has stated that insiders must wait a reasonable time after disclosure of material information before trading, and that what constitutes a reasonable time depends on the circumstances of the dissemination.

20/20 Hindsight. Remember, if your securities transactions become the subject of scrutiny, they will be viewed after-the-fact with the benefit of hindsight. As a result, before engaging in any transaction you should carefully consider how regulators and others might view your transaction in hindsight.

Transactions by Family Members. The same restrictions apply to your immediate family members, others living in your household, and any family members who do not live in your household but whose transactions in the Company’s securities are directed by you or are subject to your influence or control (collectively, “Family Members”). You are responsible for the compliance of your Family Members.

Transactions by Entities that You Influence or Control. This policy also applies to any entities that you influence or control, including any corporations, partnerships or trusts (collectively referred to as “Controlled Entities”), and transactions by these Controlled Entities should be treated for the purposes of this policy and applicable securities laws as if they were for your own account.

Transactions of Non-Residents. The same restrictions apply regardless of whether a person is resident within the United States.

Do Not Pass Information to Others. Whether the information is proprietary information about our Company or information that could have an impact on our stock price, Individuals, Family Members, and Controlled Entities must not pass the information on to others. It is illegal to advise others to trade on the basis of undisclosed material information. Liability in these cases can extend to both the “tippee” — the person to whom the insider disclosed inside information — and you, as the “tipper,” and will apply whether or not you derive any benefit from another’s actions. You should not make recommendations to others concerning the purchase or sale of securities of the Company. You should never trade, tip or recommend securities (or otherwise cause the purchase or sale of securities) while in possession of material non-public information about any other company that was obtained in the course of your involvement with the Company, including communicating material non-public information to, any other person or otherwise disclose such information without the Company’s authorization.

When Information is Public. As you can appreciate, it is also improper for any Individual to enter a trade immediately after the Company has made a public announcement of material information, including earnings releases. We impose certain “trading blackouts” to ensure that the Company’s stockholders and the investing public will be afforded the time to receive the information and act upon it. These are discussed below under the heading “Trading Blackouts.” To avoid the appearance of impropriety, as a general rule, you should not engage in any transaction until at least two full trading days have passed following the release of the information. Thus, if an announcement were made after the market close on a Monday, Thursday generally would be the first day on which you would be able to trade. If an announcement were made after the market close on a Friday, Wednesday generally would be the first eligible trading day.

Pre-Clearance of Trades of Company Stock. To provide assistance in preventing inadvertent violations and avoiding even the appearance of an improper transaction (which could result, for example, where an Individual engages in a trade while unaware of a pending major development), all members of the Board of Directors, all individuals designated as “officers” for the purposes of Rule 16a-1(f) (“Section 16 Officers”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and certain employees of the Company and its subsidiaries in a position to have access to material non-public information so designated on a pre-clearance list by our Chief Executive Officer or Chief Financial Officer from time to time, which may include legal and finance personnel, certain pre-determined insiders (“Pre-Determined Insiders”) and the Family Members and Controlled Entities of such persons, must obtain pre-clearance in writing from our General Counsel (in the absence of a General Counsel, our Chief Financial Officer) of all transactions in Company securities (e.g., acquisitions, dispositions, transfers, gifts, etc.). For purposes of this paragraph, any venture capital fund or other entity that engages in the investment of securities in the ordinary course of its business (e.g., an investment fund or partnership) other than for an employee, officer or a director’s own account, if such entity has established its own insider trading controls and procedures in compliance with applicable securities laws, shall not constitute a “Controlled Entity.” Unless a transaction is pursuant to a Trading Plan (as defined below), you must submit a written request for pre-clearance of a transaction no later than two business days before the proposed date of execution of the transaction unless you obtain a waiver from the Audit Committee of the Board of Directors. The Company shall record the date such request is received and the date each request is approved or rejected. Unless revoked, a grant of permission will normally remain valid until the close of trading five (5) business days following the day on which it was granted. If the transaction does not occur during such five-day period, the pre-clearance must be renewed by the applicant after five business days to be valid. At this time, all Individuals have been designated as Pre-Determined Insiders. You will

be notified if at a later date the Company determines that this pre-clearance policy is not applicable to you and the Company will maintain a list of all Pre-Determined Insiders.

Pre-clearance does not relieve anyone of their responsibility under SEC rules. All Individuals, whether subject to pre-clearance or not, are responsible for adherence to this Insider Trading Policy, including, but not limited to: not tipping or trading on insider information; not trading during trading blackout periods; not trading for two full trading days after earnings announcements or other significant Company announcements; and not trading in securities on a short-term basis. If any Individual is in doubt of whether or not pre-clearance is required, the Individual should inquire with our General Counsel (in the absence of a General Counsel, our Chief Financial Officer) or obtain pre-clearance as a cautionary measure.

Trading Blackouts. From time to time, the Company may require that members of the Board of Directors, officers, employees of the Company and subsidiaries of the Company and others, including Family Members and Controlled Entities, suspend trading because of developments known to the Company and not yet disclosed to the public. In that event, these persons are advised not to engage in any transaction involving the purchase or sale of the Company’s securities during that period, and should not disclose to others the fact that they have been suspended from trading (other than as strictly necessary to prevent Family Members and Controlled Entities from trading). The Company will also require the following mandatory trading blackout:

•Earnings Trading Blackouts – All members of the Board of Directors of the Company or its subsidiaries, Section 16 Officers, Pre-Determined Insiders and Individuals, and the Family Members and Controlled Entities of such persons are subject to a stock trading blackout period beginning on the 16th day of the final month of a fiscal quarter through and until two full trading days have passed after earnings for that quarter are released. All such persons whose employment or affiliation with the Company ceases during a blackout period shall remain subject to the blackout period for the duration of the blackout period.

Of course, no trading should be done at any time that an Individual is actually aware of material non-public information, including but not limited to a major undisclosed corporate development, even if a trading blackout period is not in effect at that time.

Options/RSUs. Cash exercise of options currently may be done at any time. This policy also does not apply to the exercise of a tax withholding right pursuant to which you elect to have the Company withhold shares subject to an option or restricted stock unit to satisfy tax withholding requirements which occur as a result of certain option exercises or the vesting or settlement of any restricted stock units. Same-day-sales to exercise stock options are subject to trading windows, as are any other market sale of shares subject to an option or restricted stock unit for the purpose of generating the cash needed to pay the exercise price and/or taxes (a “sell to cover”).

Exception for Approved 10b5-1 Plans. Trades by Individuals in the Company’s securities that are executed pursuant to an approved 10b5-1 trading plan (a “Trading Plan”) are not subject to the prohibition on trading on the basis of material non-public information contained in this Insider Trading Policy or to the restrictions set forth above relating to pre-clearance procedures and blackout periods. Members of the Board of Directors of the Company, Section 16 Officers, and Pre-Determined Insiders are strongly encouraged to only trade in the Company’s securities pursuant to a Trading Plan.

SEC Rule 10b5-1 provides an affirmative defense from insider trading liability under the federal securities laws for trading plans that meet certain requirements. It does not prevent someone from

bringing a lawsuit. This Insider Trading Policy permits Individuals to adopt Trading Plans with brokers that outline a pre-set plan for trading of the Company’s securities, including those received upon the exercise of options and settlement of restricted stock units. Trading Plans are to be implemented only during open windows and when the individual is not aware of any material non-public information.

Any Trading Plan must comply with applicable SEC rules and regulations, including SEC Rule 10b5-1, and be approved in writing in advance by our Chief Financial Officer or General Counsel. The establishment or termination of such a Trading Plan with respect to an Individual will be subject to applicable SEC rules regarding disclosure thereof and may otherwise be publicly announced by the Company.

Establishing a Trading Plan does not exempt Individuals from complying with the Section 16 six-month short swing profit rules or liability.

Revocation/Amendments to Trading Plans. Revocation or amendment of a Trading Plan is discouraged. An Individual may only revoke his or her Trading Plan pursuant to the terms of the Individual’s Trading Plan and in compliance with applicable SEC rules and regulations. Revocation is effected upon written notice to the broker and prior written notice should also be provided to our General Counsel. If the Individual terminates their Trading Plan, the adoption of any new Trading Plan will be subject to applicable SEC-mandated “cooling off” periods and any other restrictions then in effect by the SEC.

Under certain circumstances, a Trading Plan must be revoked. This includes circumstances such as the announcement of a merger or the occurrence of an event that would cause the transaction either to violate the law or to have an adverse effect on the Company. The Chief Financial Officer, General Counsel or their designee or any stock administrator of the Company is authorized to notify the broker in such circumstances, thereby insulating the insider in the event of revocation.

Any modification or amendment of a Trading Plan that changes the amount, price, or timing of the purchase or sale of the Company’s securities underlying the Trading Plan will be deemed to be the same as terminating the Trading Plan and adopting a new Trading Plan. As a result, the process for a modification or amendment to a Trading Plan is the same as the process for the initial establishment of a Trading Plan, including being subject to the applicable “cooling off” periods.

Post-Termination Transactions. This Insider Trading Policy continues to apply to your transactions in Company securities even after your employment, board service or consulting services terminate. If you are in possession of material non-public information when your service to the Company or a subsidiary of the Company terminates, you may not trade in Company securities until that information has become public or is no longer material. Members of the Board of Directors of the Company, Section 16 Officers, and beneficial owners of over 10% of a class of the Company’s equity securities registered under the Exchange Act should be careful not to enter into separate buy and sell transactions for six months after their respective termination of employment or service to ensure they do not violate the SEC’s short-swing profit rules.

Company Transactions. Transactions by the Company in the Company’s securities, including but not limited to any repurchases of the Company’s common stock, must comply with applicable securities laws.

5.Additional Prohibited Transactions.

We believe it is improper and inappropriate for any of the Individuals to engage in short-term or speculative transactions involving Company securities. We believe that this trading can reflect badly on the Company and that Individuals should not engage in any types of transactions that are commonly viewed as a form of “betting” for or against the Company. Accordingly, the following activities with respect to securities of the Company are prohibited, unless otherwise indicated below:

•Director and officer cashless exercise – In response to the restrictions set forth in the Sarbanes-Oxley Act of 2002, the Company will not arrange with brokers to administer cashless exercises on behalf of directors and officers of the Company. Directors and Section 16 Officers of the Company may only utilize the cashless exercise feature of their options if (i) the director or officer retains a broker independently of the Company, (ii) the Company’s involvement is limited to confirming that it will deliver the stock promptly upon payment of the exercise price and (iii) the director or officer uses a “T+1” cashless exercise arrangement, in which the Company agrees to deliver stock against the payment of the purchase price on the same day the sale of the stock underlying the option settles. Under a T+1 cashless exercise, a stock broker, the issuer, and the transfer agent of the issuer work together to make all transactions settle simultaneously. This approach is to avoid any inference that the Company has “extended credit” in the form of a personal loan to the director or executive officer. Any employee who has any questions about cashless exercises may obtain additional guidance from our Chief Financial Officer or General Counsel.

•Director and officer trading during pension and 401(k) plan blackout periods – If Company securities are available as an investment option or used as a Company match in the Company’s 401(k) plan, directors and officers of the Company are prohibited from trading Company securities during pension and 401(k) plan blackouts, if any, in response to the restrictions set forth in the Sarbanes-Oxley Act of 2002.

•Trading in securities on a short-term basis — Members of the Board of Directors of the Company, Section 16 Officers, and beneficial owners of over 10% of a class of the Company’s equity securities registered under the Exchange Act are subject to this policy are subject to the SEC’s “short-swing” profit rule, which requires the disgorgement of any profit realized from any non-exempt purchase and sale of any securities of the Company that occurs within a six-month period. In addition, as a general rule, any Company securities purchased in the open market (i.e., not including stock purchased upon exercise of an employee stock option or vesting of restricted stock units or under an employee stock purchase plan) should be held for a minimum of six months and ideally longer.

•Short sales of Company securities — This involves selling Company securities that you do not own in the expectation that the price of the securities will fall, or as part of an arbitrage transaction. Securities laws also generally prohibit members of the Board of Directors of the Company, Section 16 Officers, and beneficial owners of over 10% of a class of the Company’s equity securities registered under the Exchange Act from engaging in short sales, except in certain very limited circumstances.

•Buying or selling puts or calls, or their equivalent positions, on Company securities — This includes options and derivatives trading on any of the stock exchanges or futures exchanges, including cashless collars.

•Margin accounts or pledging. This means securities held in a margin account as collateral for a margin loan, and securities pledged (or hypothecated) as collateral for

a loan. This also includes borrowing from a brokerage firm, bank or other entity in order to buy Company securities (other than in connection with a so-called “cashless” exercise of options under the Company’s stock plans).

•Hedging or monetization transactions. Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. Such hedging transactions may permit an Individual to continue to own Company securities obtained through employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the Individual may no longer have the same objections as the Company’s other stockholders. Accordingly, hedging or monetization transactions are not permitted.

6.Company Assistance.

Any person who has any questions about specific transactions may obtain additional guidance from our Chief Financial Officer or our General Counsel.

Remember, however, you are ultimately responsible for adhering to this Insider Trading Policy and avoiding improper transactions. In this regard, it is imperative that you use your best judgment.

Section 16 Filings. While the Company expects to assist each director and Section 16 Officer (including Family Members and Controlled Entities of such persons) (collectively, “Section 16 Reporting Persons”) with such Section 16 filings, and expects such assistance to include form preparation for all Section 16 Reporting Persons other than those who do not require such assistance, the obligation to file Section 16 reports (Forms 3, 4 and 5) is a personal obligation of each such person, and the Company is not responsible for any failure to file accurate and timely Section 16 reports and each Section 16 filer should ensure that the Section 16 reports comply with the rules and requirements of Forms 3, 4, and 5 and of the federal securities laws. Each Section 16 Reporting Person must ensure that his or her broker provides the Company with detailed information (trade date, number of shares, exact price) regarding every transaction involving the securities of the Company, including gifts, transfers, pledges and all Rule 10b5-1 transactions, both in connection with mandatory pre-clearance requirements for such Section 16 Reporting Persons and immediately following execution.

7.Modifications.

This Insider Trading Policy has been approved by the Company’s Board of Directors. Officers of the Company may, from time to time, make non-substantive modifications to this Insider Trading Policy (including, without limitation, substitution of the names of the appropriate contact persons within the Company) with subsequent notice to the Company’s Board of Directors or the Nominating and Corporate Governance Committee of the Board of Directors.

8.Acknowledgements.

All directors, officers, employees, consultants and contractors of the Company and its subsidiaries will be required to acknowledge, electronically or in writing, their understanding of, and intent to comply with, this Insider Trading Policy. This agreement will constitute each such person’s consent for the Company to issue any necessary stop-transfer orders to the Company’s transfer agent to enforce compliance with this policy. As a condition of continued employment or engagement, all employees, contractors and consultants must periodically acknowledge, electronically or in writing, that they have read and agree to abide by this policy.

ACKNOWLEDGMENT

I have received and read a copy of the 1stdibs.com, Inc. Insider Trading Policy and I understand and agree to comply with the specific requirements of the policy. I agree that I will be subject to sanctions imposed by the Company, in its discretion, for violation of the Company’s policy, including dismissal for cause, and that the Company may give stop-transfer and other instructions to the Company’s transfer agent against transfer of Company securities by me in a transaction that the Company considers to be in contravention of this policy.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as our business depends on both buyers and sellers trusting that their shopping experience with us is both reliable and safe. We have integrated cybersecurity risk management into our broader risk management framework in many ways, including (i) our regular updates to the Audit Committee, (ii) our information technology and security related internal controls and (iii) our global incident response and vulnerability management programs. We view cybersecurity as a shared responsibility across the Company. All employees are required to complete yearly security training, and we periodically perform tabletop exercises with management participation. Further, our cross-functional teams work together to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. We use various security tools and processes to help prevent, identify, escalate, investigate, resolve and recover from identified vulnerabilities and security incidents in a timely manner, including, but not limited to, internal reporting, monitoring and detection tools and a vulnerability identification program. Recognizing the complexity and evolving nature of cybersecurity threats, we engage with a range of external experts, including cybersecurity consultants in evaluating and testing our risk management systems. These partnerships enable us to leverage specialized knowledge and insights, with a goal of ensuring our cybersecurity strategies and processes remain at the forefront of industry best practices. Our collaboration with these third parties includes regular audits, threat assessments, and consultation on security enhancements. In order to mitigate data or security incidents that may originate from third party vendors or suppliers, we conduct both privacy and security assessments to properly identify, prioritize, assess and remediate any third party risks, and require security and privacy addenda to our contracts where applicable. The nature of our business exposes us to cybersecurity threats and attacks that can lead to the unauthorized acquisition or access, compromise, loss, misuse or theft of our data, including personal information, confidential information or intellectual property. As of the date of this Annual Report on Form 10-K, we are not aware of any material incidents or risks from cybersecurity threats that have materially affected us, including our business strategy, results of operations, or financial condition. For a discussion of how material risks from cybersecurity threats could materially affect us, see “Risk Factors—Risks Related to Privacy, Cybersecurity, and Infrastructure—If sensitive information about our sellers and buyers or other third parties with whom we transact business is disclosed, or if we or our third-party providers are subject to cyber-attacks, use of our online marketplace could be curtailed, we may be exposed to liability, and our reputation would suffer.”
