Opinion on the Financial Statement

We have audited the accompanying balance sheet of Big Sky Growth Partners, Inc. (the “Company”) as of May 3, 2021, and the related notes to the financial statement (collectively the “financial statement”). In our opinion, the financial statement presents fairly, in all material respects, the financial position of the Company as of May 3, 2021, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

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

NOTES TO FINANCIAL STATEMENT

Note 1—Description of Organization and Business Operations

Big Sky Growth Partners, Inc. (the “Company”) is a blank check company incorporated in Delaware on February 11, 2021. 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 of the risks associated with emerging growth companies.

As of May 3, 2021, the Company had not commenced any operations. All activity for the period from February 11, 2021 (inception) through May 3, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is Big Sky Growth Partners, LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on April 28, 2021. On May 3, 2021, the Company consummated its Initial Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $17.3 million, of which $10.5 million was for deferred underwriting commissions (see Note 5). The Company granted the underwriter a 45-day option to purchase up to an additional 4,500,000 Units at the Initial Public Offering price to cover over-allotments, if any. To date, the over-allotment option has not been exercised.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 5,733,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of $8.6 million (see Note 4). If the over-allotment option is exercised in full, the Sponsor will purchase an additional 600,000 Private Placement Warrants.

Upon the closing of the Initial Public Offering and the Private Placement, $300.0 million ($10.00 per Unit) of the net proceeds of the sale of the Units in the Initial Public Offering and of the Private Placement Warrants in the Private Placement were placed in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), which invest only in direct U.S. government treasury obligations, 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 initial Business Combinations having an aggregate fair market value of at least 80% of the value of the funds held in the Trust Account (excluding the amount of deferred underwriting discounts held in trust and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company only intends to complete a Business Combination if the post-transaction company owns or acquires 50% or more of the 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 the holders (the “Public Stockholders”) of the Public Shares 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 stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (at $10.00 per Public Share, plus pro rata

NOTES TO FINANCIAL STATEMENT

interest earned in Trust Account). The per-share amount to be distributed to Public Stockholders 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 recorded at a redemption value and classified as temporary equity in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” If the Company seeks stockholder approval, the Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in connection with a Business Combination in an amount that would cause its net tangible assets to be less than $5,000,001. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated certificate of incorporation (the “Certificate of Incorporation”), 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, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder 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 Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all or are not a holder of record of Public Shares on the record date established in connection with a Business Combination. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders (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. In addition, the initial stockholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder 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 Public Shares, without the prior consent of the Company.

The holders of the Founder Shares (the “initial stockholders”) agreed not to propose an amendment to the Certificate of Incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public 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 May 3, 2023 (the “Combination Period”), and the Company’s stockholders have not amended the Certificate of Incorporation to extend such 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 and not previously released to the Company to pay its income taxes (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 Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case, to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The initial stockholders agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders 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 the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete

NOTES TO FINANCIAL STATEMENT

a Business Combination within 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 (or less than that in certain circumstances). 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 third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or by a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply 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 for the Company’s 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.

Liquidity and Capital Resources

As of May 3, 2021, the Company had approximately $2.6 million in its operating bank account, and working capital of approximately $1.8 million.

The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover for certain offering costs on the Company’s behalf in exchange for issuance of Founder Shares (as defined in Note 4), and loan from the Sponsor of approximately $96,000 under the Note (as defined in Note 4). The Company repaid the Note in full on May 4, 2021. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account. In addition, in order to 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, provide the Company Working Capital Loans (as defined in Note 4). As of May 3, 2021, there were no amounts outstanding under any Working Capital Loan.

Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using the funds held outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

NOTES TO FINANCIAL STATEMENT

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, 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 stockholder 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 an emerging growth 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 an 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 financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk will consist of a cash account in a financial institution which, at times may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. No losses have been incurred to date.

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 May 3, 2021.

Cash Held in Trust Account

As of May 3, 2021, the Company had $300.0 million in cash held in the Trust Account.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements,” approximates the carrying amounts represented in the balance sheet due to their short-term nature.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. 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 include:

F-7

BIG SKY GROWTH PARTNERS, INC.

NOTES TO FINANCIAL STATEMENT

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 480 and ASC 815-15. 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. In accordance with ASC 825-10 “Financial Instruments”, offering costs attributable to the issuance of the derivative warrant liabilities have been allocated based on their relative fair value of total proceeds and are recognized in the statement of operations as incurred.

The 7,500,000 issued in connection with the Initial Public Offering (the “Public Warrants”) and the 5,733,333 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. 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.

Use of Estimates

The preparation of financial statement in conformity with U.S. GAAP requires the Company’s 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 financial statement. Actual results could differ from those estimates.

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 statement of operations. Offering costs associated with the Class A common stock were charged to stockholders’ equity upon the completion of the Initial Public Offering.

Class A Common Stock Subject to Possible Redemption

As discussed in Note 3, all of the 30,000,000 Class A common stock sold as part of the Units in the Public Offering contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, if there is a stockholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s amended and restated certificate of incorporation. In accordance with ASC 480, conditionally redeemable Class A common stock (including shares of Class A common stock 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. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. Although the Company did not specify a maximum redemption threshold, its charter provides that currently, the Company will not redeem its public shares in an amount that would cause its net tangible assets (stockholders’ equity) to be less than $5,000,001. Accordingly, at May 3, 2021, 27,040,691 shares of Class A common stock subject to possible redemption at the redemption amount were presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.

NOTES TO FINANCIAL STATEMENT

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 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. Deferred tax assets were deemed immaterial as of May 3, 2021.

FASB 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. There were no unrecognized tax benefits as of May 3, 2021. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of May 3, 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 subject to income tax examinations by major taxing authorities since inception.

Recent Accounting Standards

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

Note 3—Initial Public Offering

On May 3, 2021, the Company consummated its Initial Public Offering of 30,000,000 Units, at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $17.3 million, inclusive of $10.5 million in deferred underwriting commissions.

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

The Company granted the underwriters a 45-day option from the date of the final prospectus relating to the Initial Public Offering to purchase up to 4,500,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price, less underwriting discounts and commissions.

Note 4—Related Party Transactions

Founder Shares

On February 19, 2021, the Sponsor paid $25,000 of the Company’s offering costs in exchange for issuance of 8,625,000 shares of the Company’s Class B common stock, par value $0.0001 per share (the “Founder Shares”). The initial stockholders agreed to forfeit up to 1,125,000 Founder Shares to the extent that the underwriters’ option to purchase additional Units was not exercised in full, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering.

The initial stockholder agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination, (x) if the last sale price of Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like)

for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the stockholders having the right to exchange their shares of common stock for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the initial stockholder with respect to any Founder Shares.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 5,733,333 Private Placement Warrants at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of $8.6 million. If the over-allotment option is exercised in full, the Sponsor will purchase an additional 600,000 Private Placement Warrants.

Each Private Placement Warrant is exercisable for one whole share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor 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 for cash and exercisable on a cashless basis so long as they are held by the initial purchasers or their 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 February 19, 2021, 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 loan was non-interest bearing and payable upon the completion of the Initial Public Offering. As of May 3, 2021, the Company borrowed approximately $96,000 under the Note. The Company repaid the Note in full on May 4, 2021.

In addition, in order to 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 would 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 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 $1.50 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 May 3, 2021, the Company had no borrowings under the Working Capital Loans.

Note 5—Commitments and Contingencies

Registration Rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any shares of Class A common stock 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 stockholder rights agreement signed upon the consummation of the Initial Public Offering. These holders will be entitled to certain demand and “piggy-back” registration rights. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

NOTES TO FINANCIAL STATEMENT

Underwriting Agreement

The underwriters were entitled to an underwriting discount of $0.20 per Unit, or $6.0 million in the aggregate, paid upon the closing of the Initial Public Offering. An additional fee of $0.35 per Unit, or $10.5 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.

If the over-allotment option is exercised in full, the underwriters will be entitled to an aggregate of $0.9 million in fees payable upon closing and an additional deferred underwriting commission of approximately $1.6 million.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 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 this financial statement. The financial statement does not include any adjustments that might result from the outcome of this uncertainty.

Note 6—Derivative Warrant Liabilities

As of May 3, 2021, the Company has 7,500,000 and 5,733,333 Public Warrants and Private Placement Warrants, respectively, outstanding.

Public Warrants may only be exercised for a whole number of shares. No fractional warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the issuance of the shares of Class A common stock 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 the initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. If a registration statement covering the issuance of the Class A common stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Company’s shares of Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy 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 so elect, it will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its commercially reasonable 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 shares of Class A common stock 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 share of Class A common stock (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 Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance), or the Newly Issued Price, (y) the aggregate gross proceeds from such issuances represent more than 50% 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 the common stock during the 20 trading day period starting on the trading day after the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, 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 $10.00 and $18.00 per share redemption trigger price described below under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” and “Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to 100% and 180% of the higher of the Market Value and the Newly Issued Price, respectively.

The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of Class A common stock 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, the Private Placement Warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees. If the Private Placement Warrants are held by someone other than the Sponsor or its 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 share of Class A common stock equals or exceeds $18.00: Once the warrants become exercisable, the Company may redeem the outstanding warrants for cash (except as described herein with respect to the Private Placement Warrants):

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

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00: After the warrants become exercisable, the Company may redeem the outstanding warrants:

NOTES TO FINANCIAL STATEMENT

The fair value of Class A common stock for the above purpose shall mean the volume weighted average last reported sale price of Class A common stock for 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 common stock 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.

The Company accounted for the 13,233,333 warrants issued in connection with the Initial Public Offering (comprised of 7,500,000 Public Warrants and 5,733,333 Private Placement Warrants) in accordance with the guidance contained in FASB ASC Topic 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability due to the existence of provisions whereby adjustments to the exercise price of the warrants is based on a variable that is not an input to the fair value of a ‘‘fixed-for-fixed’’ option and the existence of the potential for net cash settlement for the warrant holders (but not all common stockholders) in the event of a tender offer.

The accounting treatment of derivative financial instruments requires that the Company record a derivative liability upon the closing of the Initial Public Offering. Accordingly, the Company classified each warrant as a liability at its fair value and the warrants were allocated a portion of the proceeds from the issuance of the Units equal to its fair value determined by the Monte Carlo simulation. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, the warrant liability will be adjusted to fair value, with the change in fair value recognized in the Company’s statement of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification.

The following table presents information about the Company’s derivative warrant liabilities that are measured at fair value on a recurring basis as of May 3, 2021 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value:

The Company utilizes a binomial Monte-Carlo simulation to estimate the fair value of the warrants at each reporting period. The Company recognized $15,880,000 for the derivative warrant liabilities upon their issuance on May 3, 2021. The Sponsor paid an aggregate of $8,600,000 for Private Placement Warrants with an initial aggregate fair value of $6,880,000, The excess purchase price over the initial fair value on the private placement closing date is recognized as a capital contribution from the Sponsor.

The estimated fair value of the derivative warrant liabilities is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies that matches 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.

On February 19, 2021, the Company issued 8,625,000 shares of Class B common stock. Of the 8,625,000 shares of Class B common stock outstanding, up to 1,125,000 shares are subject to forfeiture, to the Company by the initial stockholders for no consideration to the extent that the underwriters’ option to purchase additional Units is not exercised in full or in part, so that the number of shares of Class B common stock will collectively equal 20% of the Company’s issued and outstanding common stock after the Initial Public Offering.

Stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of Class A common stock and holders of Class B common stock will vote together as a single class on all matters submitted to a vote of the stockholders except as required by law.

The Class B common stock will automatically convert into Class A common stock at the time of the initial Business Combination on a one-for-one basis (subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of the Business Combination, including pursuant to a specified future issuance, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the Sponsor agrees to waive such adjustment with respect to any such issuance or deemed issuance, including a specified future issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon completion of the Initial Public Offering plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with the Business Combination (after giving effect to any redemptions of shares of Class A common stock by Public Stockholders) (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination and any private placement warrants issued to the Sponsor, officers or directors upon conversion of Working Capital Loans). The Sponsor may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time.
