AMICUS THERAPEUTICS, INC.
[MISSING IMAGE: lg_amicustherape-4c.jpg]
Up to $164,206,529 of Shares of Common Stock
We previously entered into an equity distribution agreement, dated as of November 7, 2022, with Goldman Sachs & Co. LLC, or Goldman Sachs, as our sales agent, relating to shares of our common stock offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the equity distribution agreement, we could initially offer and sell shares of our common stock having an aggregate offering price of up to $250,000,000 from time to time through Goldman Sachs as our sales agent. Prior to the date of this prospectus supplement, we offered and sold an aggregate of 6,977,140 of those shares at a weighted-average public offering price of $12.30, having an aggregate offering price of $85,793,471, pursuant to the equity distribution agreement. As a result of such prior sales, as of the date of this prospectus supplement, we may offer and sell from time to time shares of our common stock having an aggregate offering price of up to $164,206,529 through Goldman Sachs pursuant to the equity distribution agreement and this prospectus supplement and the accompanying prospectus, which reflects the unused portion of the previously authorized aggregate offering amount under the equity distribution agreement of $250,000,000.
Our common stock is listed on The NASDAQ Global Market under the symbol “FOLD.” The last reported sale price of our common stock on The NASDAQ Global Market on February 20, 2025 was $9.07 per share.
Sales of our common stock, if any, under the equity distribution agreement will be made in sales deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), in ordinary brokers’ transactions, to or through a market maker, on or through The Nasdaq Global Select Market or any other market venue where the securities may be traded, in the over-the-counter market, in privately negotiated transactions, or through a combination of any such methods of sale. Goldman Sachs may also sell our common stock by any other method permitted by law. Goldman Sachs is not required to sell any specific amount of securities but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between Goldman Sachs and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.
Pursuant to the terms of the equity distribution agreement, Goldman Sachs will be entitled to compensation at a commission rate of up to 3.0% of the gross offering proceeds of shares sold under the equity distribution agreement. In connection with the sale of our common stock on our behalf, Goldman Sachs & Co. LLC may be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation paid to Goldman Sachs may be deemed to be underwriting commissions or discounts.
Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” on page S-7 of this prospectus supplement, page 3 of the accompanying prospectus and under similar headings in the other documents that are incorporated by reference in this prospectus supplement and the accompanying prospectus.
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus and the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

PROSPECTUS SUPPLEMENT SUMMARY
This summary highlights selected information contained elsewhere in, or incorporated by reference into, this prospectus supplement, and does not contain all of the information that you need to consider in making your investment decision. You should carefully read the entire prospectus supplement, including the risks of investing in our securities discussed under the heading “Risk Factors” on page S-7 of this prospectus supplement and under similar headings in the other documents that are incorporated by reference herein.
Overview
We are a global, patient-dedicated biotechnology company focused on discovering, developing, and delivering novel medicines for rare diseases. We seek to deliver the highest quality therapies that have the potential to obsolete current treatments, provide significant benefits to patients, and be first- or best-in-class. Our two marketed therapies are Galafold®, the first oral monotherapy for people living with Fabry disease who have amenable genetic variants, and Pombiliti® + Opfolda®, a novel two-component treatment for adults living with late-onset Pompe disease.
Galafold® (also referred to as “migalastat”) is approved in over 40 countries around the world, including the United States (“U.S.”), European Union (“E.U.”), United Kingdom (“U.K.”), and Japan. Additionally, Galafold® has been granted orphan drug designation in the U.S., E.U., U.K., Japan, and several other countries.
Pombiliti® + Opfolda® (also referred to as “cipaglucosidase alfa-atga/miglustat”) is approved in the U.S., the E.U., the U.K., and Switzerland. Multiple regulatory submissions and reimbursement processes with global health authorities are currently underway. Additionally, Pombiliti® + Opfolda® has been granted orphan drug designation or status in the U.S., U.K., Switzerland, and Japan and data exclusivity in the E.U.
Our Strategy
Our strategy is to create, manufacture, test, and deliver the highest quality medicines for people living with rare diseases through internally developed, jointly developed, acquired, or in-licensed products and product candidates. We are leveraging our global capabilities to develop and broaden our franchises in Fabry and Pompe disease, with focused discovery work on next-generation therapies and novel technologies.
Highlights of our progress include:
•
Commercial success in Fabry disease.   For the year ended December 31, 2024, Galafold® revenue was $458.1 million of consolidated revenue, which represented an increase of $70.3 million compared to the prior year. We continue to see strong commercial momentum and expansion into additional geographies.
​
•
Commercial and regulatory success in Pompe disease.   For the year ended December 31, 2024, Pombiliti® + Opfolda® revenue was $70.2 million of consolidated revenue. Pombiliti® + Opfolda® were approved by the European Commission (“EC”), the Medicines and Healthcare products Regulatory Agency (“MHRA”) of the U.K., and the U.S. Food and Drug Administration (“FDA”) in 2023 and the Swissmedic of Switzerland in 2024. Additionally, in 2024, we established reimbursement agreements in multiple E.U. countries, including Spain, Czechia, Italy, Switzerland, and Sweden.
​
•
Pipeline advancement and growth.   We are leveraging our global capabilities to develop and broaden our franchises in Fabry and Pompe disease, with focused discovery work on next-generation therapies and novel technologies.
​
•
Financial strength.   Total cash, cash equivalents, and marketable securities as of December 31, 2024 was $249.9 million.

Our Commercial Products and Product Candidates
Galafold® (migalastat HCl) for Fabry Disease
Our oral precision medicine Galafold® was granted accelerated approval by the FDA in August 2018 for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene (“GLA”) variant based on in vitro assay data. Galafold® was approved in the E.U. and U.K. in May 2016 as a first-line therapy for long-term treatment of adults and adolescents, aged 16 years and older, with a confirmed diagnosis of Fabry disease and who have an amenable variant. Marketing authorization approvals as well as approvals for adolescents aged 12 years and older weighing 45 kg or more have been granted in over 40 countries around the world. We plan to continue to launch Galafold® in additional countries, upon receipt of marketing authorization.
As an orally administered monotherapy, Galafold® is designed to bind to and stabilize an endogenous alpha-galactosidase A (“alpha-Gal A”) enzyme in those patients with genetic variants identified as amenable in a Good Laboratory Practice (“GLP”) cell-based amenability assay.
Pombiliti® (cipaglucosidase alfa-atga) + Opfolda® (miglustat) for Pompe Disease
We have leveraged our biologics capabilities to develop Pombiliti® + Opfolda®, a novel two-component treatment paradigm for Pompe disease. Pombiliti® + Opfolda® was approved by the EC, the MHRA and the FDA in 2023, and the Swissmedic in 2024 for adult late-onset Pompe disease (“LOPD”) patients. Additional regulatory submissions and reimbursement processes with global health authorities are currently underway.
Pombiliti® + Opfolda® consists of a uniquely engineered rhGAA enzyme, cipaglucosidase alfa-atga, with an optimized carbohydrate structure to enhance cellular uptake, administered intravenously in combination with orally administered miglustat. Miglustat binds to and stabilizes the cipaglucosidase alfa-atga in circulation reducing inactivation of rhGAA in circulation to improve the uptake of active enzyme into key disease relevant tissues. Miglustat is not an active ingredient that contributes directly to glycogen reduction.
In addition, clinical studies are ongoing in pediatric patients for both the LOPD and infantile-onset Pompe disease (“IOPD”) populations.
Next Generation Therapies
We are committed to continued innovation for all people living with Fabry or Pompe disease. As part of our long-term commitment, we are continuing discovery efforts for next-generation genetic medicines for Fabry and Pompe disease.
Strategic Alliances and Arrangements
We will continue to evaluate business development opportunities to build stockholder value and provide us with access to the financial, technical, clinical, commercial resources and intellectual property necessary to develop and market technologies or products in rare and orphan diseases. We are exploring potential collaborations, alliances, and various other business development opportunities on a regular basis. These opportunities may include business combinations, partnerships, the strategic out-licensing of certain assets, or the acquisition of preclinical-stage, clinical-stage, or marketed products or novel technologies consistent with our corporate strategy to develop and provide therapies to patients living with rare and orphan diseases.

RISK FACTORS
Investing in our common stock involves a high degree of risk. Before investing in our common stock, you should carefully consider the risks described below, together with all of the other information contained in this prospectus supplement and the accompanying prospectus and incorporated by reference herein and therein, including from our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. Some of these factors relate principally to our business and the industry in which we operate. Other factors relate principally to your investment in our securities. The risks and uncertainties described therein and below are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially and adversely affect our business and operations.
If any of the matters included in the following risks were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially and adversely affected. In such case, you may lose all or part of your investment.
Risks Related to this Offering
We have broad discretion in the use of the net proceeds of this offering and, despite our efforts, we may use the proceeds in a manner that does not increase the value of your investment.
We currently intend to use the net proceeds of this offering for support of the launch of our Pompe disease treatment, AT-GAA, in the United States, European Union and various other jurisdictions where we may seek approval, the continued expansion and commercialization of Galafold, manufacturing capabilities for AT-GAA and product candidates, including contract manufacturing partnerships, and for other general corporate, business development, and product development purposes, which may include working capital, capital expenditures, the funding of in-licensing agreements, business combinations or business collaborations for product candidates, additional technologies or other forms of intellectual property, the acquisition of assets or businesses that are complementary to our existing business and general and administrative expenses. However, we have not determined the specific allocation of the net proceeds among these potential uses. Our management will have broad discretion over the use and investment of the net proceeds of this offering, and, accordingly, investors in this offering will need to rely upon the judgment of our management with respect to the use of proceeds, with only limited information concerning our specific intentions. These proceeds could be applied in ways that do not improve our operating results or increase the value of your investment. Please see the section entitled “Use of Proceeds” on page S-12 of this prospectus supplement for further information.
If you purchase the common stock sold in this offering, you will experience immediate dilution as a result of this offering and future equity issuances.
Because the price per share of our common stock being offered may be higher than the book value per share of our common stock, you may suffer immediate substantial dilution in the net tangible book value of the common stock you purchase in this offering. See the section entitled “Dilution” on page S-13 of this prospectus supplement for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering.
Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. Purchasers of the shares we sell, as well as our existing stockholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested.
The issuance of additional shares of our common stock in future offerings could be dilutive to stockholders if they do not invest in future offerings. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, shares of our common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience further dilution.
 
S-7
 
The common stock offered hereby will be sold in “at the market offerings,” and investors who buy shares at different times will likely pay different prices.
Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold in this offering. In addition, subject to the final determination by our board of directors or a committee thereof, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.
Risks Related to our Business
We depend heavily on sales of Galafold®.and increasingly on sales of Pombiliti® + Opfolda®, in Europe, the U.S., Japan, and other geographies. If we are unable to commercialize Galafold® and Pombiliti® + Opfolda® successfully, or experience significant delays in doing so, our business could be materially harmed.
We have invested a significant portion of our efforts and financial resources in the development of Galafold® for the treatment of Fabry disease and in Pombiliti® + Opfolda® for the treatment of Late Onset Pompe Disease and rely upon sales of Galafold® and Pombiliti® + Opfolda® primarily in Europe and the U.S., and growing sales in other geographies. Our ability to generate material product revenues will depend heavily on the successful development, regulatory approval, and commercialization of Galafold® and Pombiliti® + Opfolda®. (collectively, “Our Commercial Products.”). We will continue to study Our Commercial Products in Phase 4 studies. If the results of the Phase 4 studies negatively change the benefit/risk profile of Our Commercial Products, the commercial success of Our Commercial Products may be substantially diminished. Any adverse market event with respect to Our Commercial Products, including failure to obtain and maintain sufficient market acceptance, could have a material adverse effect on our business, financial condition and results of operations. If our sales of Our Commercial Products were to decrease, or such sales were substantially or completely displaced in the market, or if we are unable to achieve and maintain sufficient market acceptance of Our Commercial Products by physicians, patients, third-party payors and others in the medical community, or if we fail to receive commercial approval in any additional jurisdictions, it could have a material adverse effect on our business, financial condition and results of operations. In addition, if Our Commercial Products were to become the subject of litigation and/or an adverse governmental action requiring us to cease sales of Our Commercial Products, such an event could have a material adverse effect on our business, financial condition and results of operations. In addition, the entry into the market of competitors with new or generic treatments, including oral, ERT and gene therapies, may erode the market for Our Commercial Products and have a material impact on our business.
Any delay or impediment in our ability to obtain regulatory approval in any region to commercialize, or, when approved, obtain coverage and adequate reimbursement from third parties, including government payors, for Our Commercial Products may cause us to be unable to meet our revenue guidance or to generate the revenues necessary to fund our future growth.
Further, the success of Our Commercial Products will depend on a number of factors, including the following:
•
obtaining a sufficiently broad label in each territory that would not unduly restrict patient access;
​
•
obtaining additional foreign approvals for Our Commercial Products;
​
•
continuing to build and maintain an infrastructure capable of supporting product sales, marketing, and distribution of Our Commercial Products in the U.S., Europe, Japan, and other territories where we pursue commercialization directly;
​
•
maintaining commercial manufacturing arrangements with third-party manufacturers;
​
•
maintaining commercial distribution agreements with third-party distributors;
​
 
S-8
 
•
launching commercial sales of Our Commercial Products, where approved, whether alone or in collaboration with others;
​
•
obtaining acceptance of Our Commercial Products, where approved, by patients, the medical community, and third-party payors;
​
•
competing effectively with other therapies, including competitor products, potential generics and gene therapies;
​
•
identifying new patients who could benefit from Our Commercial Products successfully;
​
•
continuing an acceptable safety profile of Our Commercial Products;
​
•
obtaining and maintaining patent and trade secret protection and regulatory exclusivity;
​
•
protecting and enforcing our rights in our intellectual property portfolio; and
​
•
obtaining and maintaining a commercially viable price.
​
If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize Our Commercial Products, which would materially harm our business and ability to meet our financial goals and debt covenants.

These forward-looking statements speak only as of the date of this prospectus supplement. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, even if experience or future developments make it clear that projected results expressed or implied in such statements will not be realized, except as may be required by law. You should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. Before deciding to purchase our securities, you should carefully consider the risk factors discussed and incorporated by reference in this prospectus supplement and the accompanying prospectus and in the registration statement of which this prospectus supplement and the accompanying prospectus form a part.

USE OF PROCEEDS
We may issue and sell shares of our common stock having aggregate sales proceeds of up to $164,206,529 from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.
We currently intend to use the net proceeds from the sale of the shares of common stock offered by us hereunder for, general corporate purposes, including, without limitation:
•
for support of the launch of our Pompe disease treatment, AT-GAA, in the United States, European Union and various other jurisdictions where we may seek approval;
​
•
continued expansion and commercialization of Galafold®;
​
•
manufacturing capabilities for AT-GAA and our product candidates, including contract manufacturing partnerships; and
​
•
for other general corporate, business development, and product development purposes, which may include working capital, capital expenditures, the funding of in-licensing agreements, business combinations or business collaborations for product candidates, additional technologies or other forms of intellectual property, the acquisition of assets or businesses that are complementary to our existing business and general and administrative expenses.
​
The amounts and timing of our use of the net proceeds from this offering will depend on a number of factors, such as the timing and progress of our research and development efforts, the timing and progress of any partnering and commercialization efforts, technological advances and the competitive environment for our products and product candidates. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from the sale of the shares of common stock offered by us hereunder.
Accordingly, our management will have broad discretion in the timing and application of these proceeds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in short-term, interest-bearing instruments.

DILUTION
If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the offering price per share and the as adjusted net tangible book value per share of our common stock immediately after this offering. We calculate net tangible book value per share by dividing our net tangible book value, which is tangible assets less total liabilities, by the number of outstanding shares of our common stock.
Our net tangible book value (deficit) as of December 31, 2024 was approximately ($21.0 million), or ($0.07) per share. After giving effect to the assumed sale by us of an aggregate of $164,206,529 in shares of common stock in this offering at an assumed offering price of $9.56 per share, which was the last reported sale price of our common stock on The NASDAQ Global Market on February 19, 2025, and after deducting estimated commissions and offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2024, would have been approximately $138.2 million, or $0.44 per share of common stock. This represents an immediate increase in the net tangible book value of $0.51 per share to our existing stockholders and an immediate dilution in the net tangible book value of $9.12 per share of common stock to investors purchasing common stock in this offering. The following table illustrates this calculation on a per share basis:
​
Assumed offering price per share of common stock
​ ​ ​ ​ ​ ​ ​ ​ ​ $ 9.56 ​ ​
​
Net tangible book value per share as of December 31, 2024
​ ​ ​ $ (0.07) ​ ​ ​ ​ ​ ​ ​ ​
​
Increase in net tangible book value per share after this offering
​ ​ ​ $ 0.51 ​ ​ ​ ​ ​ ​ ​ ​
​
As adjusted net tangible book value per share as of December 31, 2024 after giving effect to this offering
​ ​ ​ ​ ​ ​ ​ ​ ​ $ 0.44 ​ ​
​
Dilution per share to investors participating in this offering
​ ​ ​ ​ ​ ​ ​ ​ ​ $ 9.12 ​ ​
The number of shares of our common stock to be outstanding immediately after this offering is based on 299,041,653 shares of common stock outstanding as of December 31, 2024. Unless specifically stated otherwise, the information in this prospectus supplement is as of December 31, 2024 and excludes, as of such date:
•
26,013,223 shares of our common stock issuable upon the exercise of stock options outstanding as of December 31, 2024, at a weighted average exercise price of $12.11 per share, of which options to purchase 17,463,888 shares of our common stock were then exercisable;
​
•
7,129,605 shares of our common stock issuable upon the exercise of warrants to purchase common stock, at a weighted average exercise price of $0.01 per share;
​
•
8,277,845 shares of our common stock issuable upon the vesting of restricted stock units outstanding as of December 31, 2024;
​
•
an aggregate of 14,228,754 shares of our common stock reserved for future grants of stock options (or other similar equity instruments) under the Amended and Restated 2007 Equity Incentive Plan;
​
•
1,010,515 shares of our common stock issued since December 31, 2024 upon the exercise of outstanding stock options or vesting of restricted stock units.
​
To the extent that options or warrants are exercised, new options are issued under our equity incentive plans, or we issue additional shares of common stock in the future, there may be further dilution to investors participating in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION
We previously entered into an equity distribution agreement with Goldman Sachs & Co. LLC, as our sales agent, under which we may offer and sell from time to time our common stock having an aggregate offering price of up to $164,206,529. The sales agent may act as agent on our behalf or purchase shares of our common stock as principal.
Sales, if any, of common stock under the equity distribution agreement may be made in ordinary brokers’ transactions, to or through a market maker, on or through The NASDAQ Global Market or any other market venue where the securities may be traded, in the over-the-counter market, in privately negotiated transactions, or through a combination of any such methods of sale. The sales agent may also sell our common stock by any other method permitted by law.
The securities may be sold at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.
We will designate the maximum amount of common stock to be sold through the sales agent on a daily basis or otherwise as we and the sales agent agree and the minimum price per share at which such common stock may be sold. Subject to the terms and conditions of the equity distribution agreement, the sales agent will use its commercially reasonable efforts consistent with its normal sales and trading practices to sell on our behalf all of the designated shares of common stock. We may instruct the sales agent not to sell any common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or the sales agent, with respect to itself only, may suspend the offering of our common stock by notifying the other party.
The sales agent will provide to us written confirmation following the close of trading on The NASDAQ Global Market each day on which shares of common stock are sold under the equity distribution agreement. Each confirmation will include the number of shares of common stock sold on such day, the gross offering proceeds and the compensation payable by us to the sales agent. We will report at least quarterly the number of shares of common stock sold through the sales agent under the equity distribution agreement, the net proceeds to us (before expenses) and the compensation paid by us to the sales agent in connection with the sales of the shares of common stock.
We will pay the sales agent a commission of up to 3.0% of the gross offering proceeds of shares of common stock sold through such agent under the equity distribution agreement. We have also agreed to reimburse the sales agent for certain of its expenses in an amount up to $250,000, in addition to an amount not to exceed $25,000 per quarter thereafter.
Settlement of any sales of common stock will occur on the second business day following the date on which such sales were made (or such earlier day as is industry practice for regular-way trading). There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and the sales agent may agree.
The offering of our common stock pursuant to the equity distribution agreement will terminate upon the earlier of (i) the sale of all of our shares of common stock subject to the equity distribution agreement, or (ii) termination of the equity distribution agreement by us or by the sales agent as provided therein.
In connection with the sale of the shares of common stock on our behalf, the sales agent may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the sales agent may be deemed to be an underwriting commission or discount.
We have agreed to provide indemnification and contribution to the sales agent against certain liabilities, including civil liabilities under the Securities Act.

​
In light of these risks and uncertainties, we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions, and expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in this prospectus, particularly under “Risk Factors,” which we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Those factors and the other risk factors described herein are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Our forward-looking statements do not reflect the potential impact of any future collaborations, alliances, business combinations, partnerships, strategic out-licensing of certain assets, the acquisition of preclinical-stage, clinical-stage, marketed products or platform technologies or other investments we may make. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, investors are cautioned not to place undue reliance on such forward-looking statements.
You should read this prospectus and the documents that we incorporate by reference herein completely and with the understanding that our actual future results may be materially different from what we expect. These forward-looking statements speak only, as applicable, as of the date of this prospectus, any prospectus supplement or the documents incorporated by reference therein. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, even if experience or future developments make it clear that projected results expressed or implied in such statements will not be realized, except as may be required by law. Before deciding to purchase our securities, you should carefully consider the risk factors discussed and incorporated by reference in this prospectus and in the registration statement of which this prospectus is a part.

These underwriters may act as principal or agent in these transactions, and the sales will be made at prices related to prevailing market prices at the time of sale.
The securities we offer may be new issues of securities and may have no established trading market. The securities may or may not be listed on a securities exchange. Underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We can make no assurance as to the liquidity of, or the existence of trading markets for, any of the securities.
Certain persons participating in an offering may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with rules and regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying
 
7
 
security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a short covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.
We also may sell any of the securities through agents designated by us from time to time. We will name any agent involved in the offer or sale of these securities and will list commissions payable by us to these agents in the applicable prospectus supplement. These agents will be acting on a best efforts basis to solicit purchases for the period of its appointment, unless stated otherwise in the applicable prospectuses.
We may sell any of the securities directly to purchasers. In this case, we will not engage underwriters or agents in the offer and sale of these securities.

DESCRIPTION OF OUR COMMON STOCK
The following summary of the terms of our common stock is subject to and qualified in its entirety by reference to our certificate of incorporation and by-laws, in each case, as may be amended from time-to-time, copies of which are on file with the SEC as exhibits to previous SEC filings. Please refer to “Where You Can Find More Information” below for directions on obtaining these documents.
As of February 19, 2025, we are authorized to issue 500,000,000 shares of common stock, $0.01 par value per share. As of February 18, 2025, we had 307,239,840 shares of common stock outstanding.
General
Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. An election of directors by our stockholders shall be determined by a plurality of the votes present in person or represented by proxy at the applicable meeting of stockholders. Holders of common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of any outstanding preferred stock.
In the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.
Transfer Agent and Registrar
The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC.

DESCRIPTION OF OUR PREFERRED STOCK
We are authorized to issue up to 10,000,000 shares of preferred stock, par value $0.01 per share. As of February 19, 2025, there were no shares of our preferred stock outstanding.
Our board of directors may, without further action by our stockholders, from time to time, direct the issuance of shares of preferred stock in series and may, at the time of issuance, determine and fix the powers, designations, preferences, and relative, participating, optional, or other special rights, if any, and the qualifications and restrictions, if any, of such preferences and rights, including without limitation dividend rights, conversion rights, voting rights (if any), redemption privileges, and liquidation preferences, of such series of preferred stock (which need not be uniform among series). Satisfaction of any dividend preferences of outstanding shares of our preferred stock would reduce the amount of funds available for the payment of dividends on shares of our common stock. Holders of shares of our preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of the Company before any payment is made to the holders of shares of our common stock. In some circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management. Upon the affirmative vote of our board of directors, without stockholder approval, we may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of our common stock.
If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the certificate establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:
•

​

DESCRIPTION OF OUR DEBT SECURITIES
This section describes the general terms and provisions of the debt securities that we may offer under this prospectus, any of which may be issued as convertible or exchangeable debt securities. We will set forth the particular terms of the debt securities we offer in a prospectus supplement. The extent, if any, to which the following general provisions apply to particular debt securities will be described in the applicable prospectus supplement. The following description of general terms relating to the debt securities and the indenture under which the debt securities will be issued are summaries only and therefore are not complete. You should read the indenture and the prospectus supplement regarding any particular issuance of debt securities.
We will issue any debt securities under an indenture to be entered into between us and the trustee identified in the applicable prospectus supplement. The terms of the debt securities will include those stated in the indenture any amendment or supplement thereto and those made part of the indenture by reference to the Trust Indenture Act of 1939 (the “Trust Indenture Act”), as in effect on the date of the indenture. We have filed or will file a copy of the form of indenture as an exhibit to the registration statement in which this prospectus is included.
The following statements relating to the debt securities and the indenture are summaries, qualified in their entirety by reference to the detailed provisions of the indenture and the final form indenture which will be filed with a future prospectus supplement and any amendment or supplement thereto.
General
We may issue the debt securities in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will describe the particular terms of each series of debt securities in a prospectus supplement relating to that series, which we will file with the SEC.

​

the issue price or prices, expressed as a percentage of the aggregate principal amount of the debt securities;
​

​

​

​
All debt securities of one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of any holder, for issuances of additional debt securities of that series with the same terms as the original debt securities of that series (other than the issue price and the interest accrued prior to the issue date of the additional debt securities). We may issue discount debt securities that provide for an amount less than the stated principal amount to be due and payable upon acceleration of the maturity of such debt securities in accordance with the terms of the indenture. We may also issue debt securities in bearer form, with or without coupons. If we issue discount debt securities or debt securities in bearer form, we will describe material U.S. federal income tax considerations and other material special considerations which apply to these debt securities in the applicable prospectus supplement. We may issue debt securities denominated in or payable in a foreign currency or currencies or a foreign currency unit or units.

Exchange and/or Conversion Rights
We may issue debt securities which can be exchanged for or converted into shares of our common stock or preferred stock. If we do, we will describe the terms of exchange or conversion in the prospectus supplement relating to these debt securities.
Transfer and Exchange
We may issue debt securities that will be represented by either:
•
“book-entry securities,” which means that there will be one or more global securities registered in the name of a depositary or a nominee of a depositary; or
​
•
“certificated securities,” which means that they will be represented by a certificate issued in definitive registered form.
​
We will specify in the prospectus supplement applicable to a particular offering whether the debt securities offered will be book-entry or certificated securities.
Certificated Debt Securities
If you hold certificated debt securities issued under an indenture, you may transfer or exchange such debt securities in accordance with the terms of the indenture. You will not be charged a service charge for
 
15
 
any transfer or exchange of certificated debt securities but may be required to pay an amount sufficient to cover any tax or other governmental charge payable in connection with such transfer or exchange.
Global Securities
The debt securities of a series may be issued in the form of one or more global securities that will be deposited with a depositary or its nominees identified in the prospectus supplement relating to the debt securities. In such a case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding debt securities of the series to be represented by such global security or securities.
Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a global security may not be registered for transfer or exchange except as a whole by the depositary for such global security to a nominee of the depositary and except in the circumstances described in the prospectus supplement relating to the debt securities. The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such series.
Protection in the Event of Change of Control
Any provision in an indenture that governs our debt securities covered by this prospectus that includes any covenant or other provision providing for a put or increased interest or that would otherwise afford holders of our debt securities additional protection in the event of a recapitalization transaction, a change of control of the Company, or a highly leveraged transaction will be described in the applicable prospectus supplement.
Covenants
Unless otherwise indicated in this prospectus or the applicable prospectus supplement, our debt securities may not have the benefit of any covenant that limits or restricts our business or operations, the pledging of our assets or the incurrence by us of indebtedness. We will describe in the applicable prospectus supplement any material covenants in respect of a series of debt securities.
Consolidation, Merger and Sale of Assets
We may agree in any indenture that governs the debt securities of any series covered by this prospectus that we will not consolidate with or merge into any other person or convey, transfer, sell or lease our properties and assets substantially as an entirety to any person, unless:
•
we are the surviving entity of any such merger or consolidation or the entity formed by such merger or consolidation shall be organized under the laws of the United States of America, or any state thereof or the District of Columbia, and shall expressly assume by a supplemental indenture all of our obligations related to such debt securities; and
​
•
immediately before and immediately after the merger or consolidation, no default or event of default shall have occurred and be continuing.
​
Notwithstanding the foregoing, the indenture may allow certain transactions, including, but not limited to, a merger between us and our wholly owned subsidiary or a merger between us and our affiliate for the purpose of converting us into a corporation under the laws of the United States of America, or any state thereof or the District of Columbia, or for the purpose of creating or collapsing a holding company structure.
Defaults and Notice
The debt securities of any series will contain events of default to be specified in the applicable prospectus supplement, which may include, without limitation:
•
failure to pay the principal of, or premium, if any, on any debt security of such series when due and payable (whether at maturity, upon redemption, acceleration or otherwise);
​
 
16
 
•
failure to make a payment of any interest on any debt security of such series when due and payable and such failure continues for a period of 30 days;
​
•
our failure to perform or observe any other covenants or agreements in the indenture with respect to the debt securities of such series and such failure continues for a period of 60 days;
​
•
after written notice from the trustee or holders of 25% in the aggregate principal amount of the then-outstanding debt securities of such series; and
​
•
certain events relating to our or our significant subsidiaries’ bankruptcy, insolvency or reorganization.
​
If an event of default with respect to debt securities of any series shall occur and be continuing, we may agree that the trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding debt securities of such series may declare the principal amount of all debt securities of such series or such other amount or amounts as the debt securities or supplemental indenture with respect to such series may provide, to be due and payable immediately. Any provisions pertaining to events of default and any remedies associated therewith will be described in the applicable prospectus supplement.
Any indenture that governs our debt securities covered by this prospectus may require that the trustee under such indenture shall, within 90 days after the trustee knows of the occurrence of a default, give to holders of debt securities of any series notice of all uncured defaults with respect to such series known to it. However, except in the case of a default that results from the failure to make any payment of the principal of, or interest or premium, if any, on the debt securities of any series, the trustee may withhold such notice if it in good faith determines that the withholding of such notice is in the interest of the holders of debt securities of such series. Any terms and provisions relating to the foregoing types of provisions will be described in further detail in the applicable prospectus supplement.
Any indenture that governs our debt securities covered by this prospectus will contain a provision entitling the trustee to be indemnified by holders of debt securities before instituting a proceeding or pursuing a remedy under the indenture at the request of such holders. Any such indenture may provide that the holders of at least a majority in aggregate principal amount of the then-outstanding debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee with respect to the debt securities of such series. However, the trustee under any such indenture may decline to follow any such direction if, among other reasons, the trustee determines that the actions or proceedings as directed may not lawfully be taken, would involve the trustee in personal liability or would be unduly prejudicial to the holders of the debt securities of such series not joining in such direction.
Any indenture that governs our debt securities covered by this prospectus may permit the holders of such debt securities to institute a proceeding with respect to such indenture, subject to certain conditions, which will be specified in the applicable prospectus supplement and which may include that the holders of at least 25% in aggregate principal amount of the debt securities of such series then-outstanding make a prior written request upon the trustee to exercise its power under the indenture, and offer reasonable indemnity to the trustee. Even so, such holders may have an absolute right to receipt of the principal of, or premium, if any, and interest when due, to require conversion or exchange of debt securities if such indenture provides for convertibility or exchangeability at the option of the holder and to institute suit for the enforcement of such rights. Any terms and provisions relating to the foregoing types of provisions will be described in further detail in the applicable prospectus supplement.
Modification of the Indenture
We and the trustee may modify any indenture that governs our debt securities of any series covered by this prospectus with or without the consent of the holders of such debt securities, under certain circumstances to be described in a prospectus supplement.
Defeasance; Satisfaction and Discharge
The prospectus supplement will outline the conditions under which we may elect to have certain of our obligations under the indenture discharged and under which the indenture obligations will be deemed to be satisfied.
 
17
 
Any indenture that governs our debt securities covered by this prospectus may provide that we may discharge our obligations under such debt securities and the indenture with respect to such debt securities if:
•
either (A) there shall have been canceled by the trustee under the indenture, or delivered to the trustee for cancellation, all debt securities of such series theretofore authenticated and delivered or (B) all such debt securities not theretofore delivered to the trustee for cancellation have become due and payable or will become due and payable within one year or are to be called for redemption within one year under irrevocable arrangements for the giving of notice of redemption by the trustee;
​
•
we have irrevocably deposited or caused to be deposited with the trustee funds in an amount sufficient to pay and discharge the entire indebtedness on the debt securities not theretofore delivered to the trustee for cancellation, for principal, premium, if any, and interest to the maturity or date of redemption;
​
•
we have paid all other sums payable by us under the indenture or deposited all other required sums with the trustee; and
​
•
the deposit will not result in a breach or violation of, or constitute a default under, any other instrument or agreement to which we are a party or to which we are bound.
​
Any indenture that governs our debt securities covered by this prospectus may provide that we may be discharged from our obligations with respect to any debt securities, subject to certain exceptions. Further, any indenture that governs our debt securities covered by this prospectus may provide that we may be released from our obligations under certain sections of such indenture, subject to certain exceptions. In either case, such indenture may provide that certain conditions must be satisfied prior to such discharge or release, including, but not limited to:
•
we shall have irrevocably deposited with the trustee, in trust, for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the holders of the debt securities, (a) money, (b) U.S. or foreign government obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money, or (c) a combination thereof, in an amount sufficient to pay the entire indebtedness on such debt securities in respect of principal, accrued interest and premium, if any;
​
•
there shall be no continuing default or event of default with respect to such debt securities at the time of the deposit or after giving effect thereto;
​
•
there shall not be certain conflicting interest for purposes of the Trust Indenture Act;
​
•
such actions shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which we are bound;
​
•
we shall have delivered a legal opinion relating to certain tax matters; and
​
•
we shall have delivered a legal opinion and certain other certificates relating to the satisfaction of the required conditions.
​
Regarding the Trustee
We will identify the trustee and any relationship that we may have with such trustee, with respect to any series of debt securities, in the prospectus supplement relating to the applicable debt securities. You should note that if the trustee becomes a creditor of the Company, the indenture and the Trust Indenture Act limit the rights of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim, as security or otherwise. The trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates. If, however, the trustee acquires any “conflicting interest” within the meaning of the Trust Indenture Act, it must eliminate such conflict or resign.
Governing Law
The law governing the indenture and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York.

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE
The SEC allows us to “incorporate by reference” information into this prospectus. This means that we can disclose important information to you by referring you to other documents we have filed separately with the SEC, without actually including the specific information in this prospectus. The information incorporated by reference is considered to be part of this prospectus, and information that we file later with the SEC (and that is deemed to be “filed” with the SEC) will automatically update, and may supersede, information in this prospectus. We incorporate by reference into this prospectus and the registration statement of which this prospectus is a part the information or documents listed below that we have filed with the SEC (Commission File No. 001-33497):
•
​
•
​
•
The description of our common stock contained in our registration statement on Form 8-A (File No. 001-33497) filed with the SEC on May 23, 2007, under the Exchange Act, and any amendment or report filed for the purpose of updating such description, including Exhibit 4.3 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the SEC on February 19, 2025.
​
We also incorporate by reference any future filings (except as specifically enumerated above, other than any filings or portions of such reports that are not deemed “filed” under the Exchange Act in accordance with the Exchange Act and applicable SEC rules, including current reports furnished under Item 2.02 or Item 7.01 of Form 8-K and exhibits filed on such form that are related to such items unless such Form 8-K expressly provides to the contrary) made with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, including those made after the date of the initial filing of the registration statement of which this prospectus forms a part, until we file a post-effective amendment that indicates the termination of the offering of the securities made by this prospectus and will become a part of this prospectus from the date that such documents are filed with the SEC. Information in such future filings updates and supplements the information provided in this prospectus. Any statements in any such future filings will automatically be deemed to modify and supersede any information in any document we previously filed with the SEC that is incorporated or deemed to be incorporated herein by reference to the extent that statements in the later filed document modify or replace such earlier statements.
To obtain copies of these filings, see “Where You Can Find More Information” on page 22 of this prospectus.
