STRE Supernova Partners Acquisition Company III Ltd

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Note 1 - Description of Organization, Business Operations and Liquidity

Supernova Partners Acquisition Company III, Ltd. (the “Company”) was incorporated as a Cayman Islands exempted company on December 24, 2020. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all the risks associated with emerging growth companies.

As of June 30, 2022, the Company had not commenced any operations. All activity for the period from December 24, 2020 (inception) through June 30, 2022, relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below, and since the Initial Public Offering, the search or an initial Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on from the proceeds from the Initial Public Offering held in the trust account.

The Company’s sponsor is Supernova Partners III LLC, a Cayman Islands exempted company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on March 22, 2021. On March 25, 2021, the Company consummated its Initial Public Offering of 25,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $250.0 million, and incurring offering costs of approximately $14.3 million, of which approximately $8.8 million was for deferred underwriting commissions (see Note 5).

The Company granted the underwriters in the IPO (the “Underwriters”) a 45-day option to purchase up to 3,750,000 additional Units to cover over-allotments, if any. The Underwriters exercised the over-allotment option in part and on April 1, 2021 purchased an additional 3,103,449 Units, generating gross proceeds of approximately $31.0 million (the “Over-Allotment”), and incurring additional offering costs of approximately $1.7 million in offering costs, of which approximately $1.1 million was for deferred underwriting fees.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 3,500,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), at a price of $2.00 per Private Placement Warrant with the Sponsor, generating gross proceeds of $7.0 million (see Note 4).

Simultaneously with the closing of the Over-Allotment on April 1, 2021, the Company consummated the second closing of the Private Placement, resulting in the purchase of an aggregate of an additional 310,345 Private Placement Warrants by the Sponsor, generating gross proceeds to the Company of approximately $621,000.

In addition, the Sponsor agreed to forfeit up to 937,500 Class B ordinary shares, par value $0.0001 (the “Founder Shares”) to the extent that the over-allotment option was not exercised in full by the Underwriters. The Underwriters partially exercised their over-allotment option on April 1, 2021, and subsequently on May 9, 2021, the Sponsor forfeited 161,638 Class B ordinary shares.

Upon the closing of the Initial Public Offering, the Over-Allotment, and the Private Placement, $281.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (“Trust Account”), located in the United States at J.P. Morgan Chase Bank, N.A., with American Stock Transfer & Trust Company acting as trustee, and invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

initial Business Combinations having an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the amount of any deferred underwriting discount held in trust) at the time of the signing of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide its holders of its Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (at $10.00 per Public Share). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the Underwriters (as discussed in Note 5). These Public Shares were classified as temporary equity in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated memorandum and articles of association (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company has adopted an insider trading policy which will require insiders to: (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material non-public information and (ii) to clear all trades with the Company’s legal counsel prior to execution. In addition, the initial shareholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

Notwithstanding the foregoing, the Amended and Restated Memorandum and Articles of Association will provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

The Company’s Sponsor, officers and directors (the “initial shareholders”) agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association that would modify the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or March 25, 2023 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation

distributions, if any) and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject, in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to complete its initial Business Combination within the Combination Period.

The Sponsor agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or members of the Company’s management team acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The Underwriters agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period, and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the Underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, except the independent registered public accounting firm, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Going Concern

As of June 30, 2022, the Company had approximately $0.2 million in its operating bank account and a working capital deficit of approximately $0.8 million.

The Company has incurred and expects to incur significant costs in pursuit of its financing and acquisition plans. In connection with the Company’s assessment of going concern considerations, the Company has until March 25, 2023 to consummate a Business Combination. It is uncertain that the Company will be able to consummate a Business Combination by this time. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition and mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 global pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, and/or search for a target company, the specific impact is not readily determinable as of the date of these unaudited condensed financial statements. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2 - Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.

The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on March 25, 2022. In the Annual Report on Form 10-K the Company had a typographical error in the Accumulated deficit balance reported on the Company’s balance sheet as of December 31, 2021, whereby the reported accumulated deficit of $(18) should have been reported as ($18,641,337). The accumulated deficit amount was reported correctly in the statements of changes in shareholders’ equity (deficit) for the year ended December 31, 2021 within the Annual Report on Form 10-K. The Company has corrected this typographical error in the accompanying unaudited condensed balance sheets.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s unaudited condensed financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ from those estimates.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and investments held in the Trust Account. Cash is maintained in accounts with financial institutions, which, at times may exceed the Federal Depository Insurance Corporation coverage limit of $250,000, and investments held in the Trust Account. As of June 30, 2022 and December 31, 2021, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of June 30, 2022 and December 31, 2021.

Investments Held in the Trust Account

The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the condensed balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income on investments held in the Trust Account in the accompanying statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed balance sheets.

Fair Value Measurements

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). These tiers consist of:

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Derivative Warrant Liabilities

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity is re-assessed at the end of each reporting period.

The warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model. Subsequent to the separate listing and trading of the Public Warrants the fair value of the Public Warrants has been measured based on the observable listed prices for such warrants and the fair value of the Private Warrants are measured using a Black-Scholes Option Pricing Model. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Offering Costs Associated with the Initial Public Offering

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities are expensed as incurred, presented as non-operating expenses in the statements of operations. Offering costs associated with the Class A ordinary shares were charged against the carrying value of the Class A ordinary shares upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Class A Ordinary Shares Subject to Possible Redemption

The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of June 30, 2022 and December 31, 2021, the Company had 28,103,449 Class A ordinary shares subject to possible redemption presented as temporary equity, outside of the shareholders’ equity section of the Company’s condensed balance sheets.

Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. Effective with the closing of the Initial Public Offering (including exercise of the over-allotment option), the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Share-based Compensation

The transfer of the Founder Shares is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The Founders Shares were granted subject to a performance condition (i.e., the occurrence

10

SUPERNOVA PARTNERS ACQUISITION COMPANY III, LTD.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

of a Business Combination). Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of the date of issuance of this Form 10-Q, the Company determined that a Business Combination is not considered probable, and, therefore, no stock-based compensation expense has been recognized. Stock-based compensation would be recognized at the date a Business Combination is considered probable (i.e., upon completion of a Business Combination) in an amount equal to the number of Founders Shares that ultimately vest multiplied times the grant date fair value per share (unless subsequently modified) less the amount initially received for the purchase of the Founders Shares.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of June 30, 2022 and December 31, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered an exempted Cayman Islands company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net Income (Loss) Per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per ordinary share is calculated by dividing the net income (loss) by the weighted average shares of ordinary shares outstanding for the respective period.

The calculation of diluted net income (loss) per ordinary share does not consider the effect of the warrants issued in connection with the Initial Public Offering (including exercise of the over-allotment option) and the Private Placement to purchase an aggregate of 9,431,035 shares of Class A ordinary shares in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

Recent Accounting Pronouncements

The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed financial statements.

Note 3 - Initial Public Offering

On March 25, 2021, the Company consummated its Initial Public Offering of 25,000,000 Units, at $10.00 per Unit, generating gross proceeds of $250.0 million, and incurring offering costs of approximately $14.3 million, of which approximately $8.8 million was for deferred underwriting commissions.

The Company granted the Underwriters a 45-day option to purchase up to 3,750,000 additional Units to cover over-allotments, if any. The Underwriters partially exercised the over-allotment option and on April 1, 2021, purchased an additional 3,103,449 Units, generating gross proceeds of approximately $31.0 million, and incurring additional offering costs of approximately $1.7 million in offering costs, of which approximately $1.1 million was for deferred underwriting fees.

Each Unit consists of one Class A ordinary share, and one-fifth of one redeemable warrant (each, a “Public Warrant”). Each Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment (see Note 6).

Note 4 - Related Party Transactions

Founder Shares

On December 31, 2020, the Sponsor paid $25,000 to cover certain expenses of the Company in consideration of the Founder Shares. On January 14, 2021, the Company effected a share dividend of 1,437,500 Class B ordinary shares, resulting in an aggregate of 7,187,500 Class B ordinary shares outstanding. On March 1, 2021, our Sponsor transferred 28,750 Founder Shares to each of our five independent director nominees. The fair value of the 143,750 Founder Shares granted to the five independent director nominees was $710,000. The initial shareholders agreed to forfeit up to 937,500 Founder Shares to the extent that the over-allotment option is not exercised in full by the Underwriters, so that the Founder Shares will represent 20% of the Company’s issued and outstanding shares after the Initial Public

12

SUPERNOVA PARTNERS ACQUISITION COMPANY III, LTD.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Offering. On April 1, 2021, the Underwriters partially exercised the over-allotment option to purchase an additional 3,103,449 Units. Subsequently, on May 9, 2021, the Sponsor forfeited 161,638 Class B ordinary shares.

The initial shareholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (i) one year after the completion of the initial Business Combination or (ii) the date following the completion of the initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the shareholders having the right to exchange their ordinary shares for cash, securities or other property. Notwithstanding the foregoing, if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 120 days after the initial Business Combination, the Founder Shares will be released from the lockup.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 3,500,000 Private Placement Warrants, at a price of $2.00 per Private Placement Warrant with the Sponsor, generating gross proceeds of $7.0 million.

Simultaneously with the closing of the over-allotment on April 1, 2021, the Company consummated the second closing of the Private Placement, resulting in the purchase of an aggregate of an additional 310,345 Private Placement Warrants by the Sponsor, generating gross proceeds to the Company of approximately $621,000.

Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable except as described below in Note 6 and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Loans

On December 31, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This Note was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed $300,000 under the Note and repaid the Note in full on March 25, 2021.

In addition, in order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $2.00 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of June 30, 2022 and December 31, 2021, the Company had no borrowings under the Working Capital Loans.

Note 5 - Commitments and Contingencies

Registration and Shareholder Rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) were entitled to registration rights pursuant to a registration and shareholder rights agreement signed upon consummation of the Initial Public Offering. These holders were entitled to certain demand and “piggyback” registration rights. However, the registration and shareholder rights agreement provided that the Company would not permit any registration statement filed under the Securities Act to become effective until the termination of the applicable lock-up period for the securities to be registered. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Underwriters were entitled to an underwriting discount of $0.20 per unit, or $5.0 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per unit, or approximately $8.8 million in the aggregate will be payable to the Underwriters for deferred underwriting commissions. The deferred fee will become payable to the Underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

The Underwriters partially exercised the over-allotment option and on April 1, 2021 purchased an additional 3,103,449 Units, generating gross proceeds of approximately $31.0 million, and incurred additional offering costs of approximately $1.7 million in offering costs, of which approximately $1.1 million will be payable to the Underwriters for additional deferred underwriting fees.

Note 6 - Warrants

As of June 30, 2022 and December 31, 2021, the Company had 5,620,690 and 3,810,345 Public Placement Warrants and Private Placement Warrants outstanding.

Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable 30 days after the completion of a Business Combination or provided in each case that the Company has an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a Business Combination, the Company will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the Public Warrants. If the shares issuable upon exercise of the warrants are not registered under the Securities Act, the Company will be required to permit holders to exercise their warrants on a cashless basis. However, no warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. Notwithstanding the above, if the

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Company’s Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company elects, the Company will not be required to file or maintain in effect a registration statement, but the Company will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the initial shareholders or their affiliates, without taking into account any Founder Shares held by the initial shareholders or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of Class A ordinary shares during the 10 trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, then the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described under “Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00” and “Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00“ will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described under “Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, except as described below, the Private Placement Warrants will be non-redeemable so long as they are held by the initial purchasers or such purchasers’ permitted transferees. If the Private Placement Warrants are held by someone other than the initial shareholders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00: 

Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

The Company will not redeem the warrants as described above unless an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period. If and when

SUPERNOVA PARTNERS ACQUISITION COMPANY III, LTD.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

the warrants become redeemable by the Company, it may exercise its redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00: 

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

The “fair market value” of Class A ordinary shares for the above purpose shall mean the volume weighted average price of Class A ordinary shares during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 Class A ordinary shares per warrant (subject to adjustment).

In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 7 - Class A Ordinary Shares Subject to Possible Redemption

The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of future events. The Company is authorized to issue 500,000,000 shares of Class A ordinary shares with a par value of $0.0001 per share. Holders of the Company’s Class A ordinary shares are entitled to one vote for each share. As of June 30, 2022 and December 31, 2021, there were 28,103,449 shares of Class A ordinary shares outstanding, which were all subject to possible redemption and are classified outside of permanent equity in the condensed balance sheets.

Note 8 - Shareholders’ Deficit

Preference Shares - The Company is authorized to issue 5,000,000 preference shares, with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of June 30, 2022 and December 31, 2021, there were no preference shares issued or outstanding.

Class A Ordinary Shares - The Company is authorized to issue 500,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of June 30, 2022 and December 31, 2021, there were 28,103,449 and Class A ordinary shares issued and outstanding, all subject to possible redemption and classified as temporary equity (see Note 7).

Class B Ordinary Shares - The Company is authorized to issue 50,000,000 Class B ordinary shares with a par value of $0.0001 per share. On December 31, 2020, the Company issued 5,750,000 Class B ordinary shares. On January 14, 2021, the Company effected a share dividend of 1,437,500 Class B ordinary shares resulting in an aggregate of 7,187,500 Class B ordinary shares outstanding. Of the 7,187,500 Class B ordinary shares outstanding, up to 937,500 shares were subject to forfeiture to the Company by the initial shareholders on a pro rata basis for no consideration to the extent that the Underwriters’ over-allotment option is not exercised in full or in part, so that the initial shareholders will collectively own 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. The Underwriters partially exercised their over-allotment option on April 1, 2021, and subsequently on May 9, 2021, the Sponsor forfeited 161,638 Class B ordinary shares. As of June 30, 2022 and December 31, 2021, there were 7,025,862 Class B ordinary shares outstanding, none subject to forfeiture.

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of shareholders, except as required by law.

The Class B ordinary shares will automatically convert into Class A ordinary shares concurrently with or immediately following the consummation of the initial Business Combination on a one-for-one basis, subject to adjustment for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares or equity-linked securities are issued or deemed issued in connection with the initial Business Combination, the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 20% of the total number of Class A ordinary shares outstanding after such conversion (after giving effect to any redemptions of Class A ordinary shares by Public Shareholders), including the total number of Class A ordinary shares issued, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Warrants issued to the Sponsor, officers or directors upon conversion of Working Capital Loans; provided that such conversion of Class B ordinary shares will never occur on a less than one-for-one basis.

 December 31, 2021

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1, 2, and 3 during the six months ended June 30, 2022 or 2021.

Level 1 assets include investments in money market funds invested in government securities. The Company uses inputs such as actual trade data, benchmark yields, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model. Subsequent to the separate listing and trading of the Public Warrants the fair value of the Public Warrants has been measured based on the observable listed prices for such warrants and the fair value of the Private Warrants are measured using a Black-Scholes Option Pricing Model. For the three months ended June 30, 2022 and 2021, the Company recognized a non-cash gain/(loss) resulting from a decrease/(increase) in the fair value of the derivative warrant liabilities of approximately $2.8 million and $(1.5) million, respectively, presented as change in fair value of derivative warrant liabilities on the accompanying unaudited condensed statements of operations. For the six months ended June 30, 2022 and 2021, the Company recognized a non-cash gain/(loss) resulting from a decrease/(increase) in the fair value of liabilities of approximately $7.0 million and $(1.7) million, respectively, presented as change in fair value of derivative warrant liabilities on the accompanying unaudited condensed statements of operations.   

The estimated fair value of the Private Placement Warrants and the Public Warrants prior to being separately listed and traded, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation and the Black-Scholes Option Pricing Model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its ordinary share warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s ordinary shares that matches

18

SUPERNOVA PARTNERS ACQUISITION COMPANY III, LTD.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The following table provides quantitative information regarding Level 3 fair value measurement inputs at their measurement dates:

The changes in the fair value of Level 3 derivative warrant liabilities for the three and six months ended June 30, 2022 and 2021 are summarized as follows:
