MSDA MSD Acquisition Corporation

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Note 1 — Description of Organization and Business Operations

MSD Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on February 5, 2021. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses that the Company has not yet identified (“Business Combination”).

As of June 30, 2021, the Company had not yet commenced operations. All activity for the period from February 5, 2021 (inception) through June 30, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described below, and, subsequent to the Initial Public Offering, identifying a target company for a Business Combination. 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 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 MSD Sponsor Holdings, LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on March 24, 2021. On March 29, 2021, the Company consummated its Initial Public Offering of 57,500,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), including 7,500,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $575.0 million, and incurring offering costs of approximately $33 million, of which approximately $20.1 million was for deferred underwriting commissions (see Note 6). Each Unit consists of one Class A ordinary share and one-fifth of one redeemable warrant (“Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 7)

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 9,333,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant with the Sponsor, generating gross proceeds of $14.0 million (see Note 4).

Upon the closing of Initial Public Offering and the Private Placement, $575.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement were placed in a trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and will be invested in United States “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”), having a maturity of 185 days or less (“Government Securities”) or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations (“Money Market Funds” and collectively with Government Securities, the “Trust Investments”), 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 its Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target business or otherwise acquires a controlling interest in the target business 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 the 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. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account ($10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations).

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

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 6). These Public Shares were recorded at a redemption value and classified as temporary equity, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”). 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 applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which was adopted by the Company upon the consummation of the Initial Public Offering (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 (the “SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, a shareholder approval of the transactions is required by applicable law or stock exchange listing requirements, or the Company decides to obtain shareholder approval for business or other 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 or whether they were a Public Shareholder on the record date for the general meeting held to approve the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the holders of the Founder Shares prior to this Initial Public Offering (the “Initial Shareholders”) agreed to vote their Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. 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. In addition, the Company agreed not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.

Notwithstanding the foregoing, the Company’s 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, directors and director nominees agreed not to propose an amendment to the Company’s Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the Company’s obligation to allow the redemption of its Public Shares in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination within 24 months from the closing of the Initial Public Offering, or March 29, 2023 (the “Combination Period”), or (B) with respect to any other provisions relating to shareholders’ rights or pre-initial business combination activity, 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 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 (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and 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.

In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay the Company’s taxes payable (less taxes payable and up to $100,000 of interest to pay dissolution expenses).

MSD ACQUISITION CORP.
NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The Initial Shareholders 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 Initial Shareholders should 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 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution in the Trust Account will be less than the $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, 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 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 prospective target business who 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”). 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 vendors, service providers (except 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. There can be no guarantee that the Company will be successful in obtaining such waivers from its targeted vendors and service providers.

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 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 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 unaudited condensed financial statements 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.

Liquidity and Capital Resources

As of June 30, 2021, the Company had $0.7 million in its operating bank account and working capital of approximately $1.5 million.

The Company’s liquidity needs through June 30, 2021 were satisfied through $25,000 paid by the Sponsor to cover certain expenses in exchange for the issuance of the Founder Shares, a loan of approximately $192,000 from the Sponsor pursuant to the Note (as defined in Note 5), and the proceeds from the consummation of the Private Placement not held in the Trust Account of $2.5 million. The Company repaid the Note in full on March 30, 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, provide the Company Working Capital Loans (as defined in Note 5). As of June 30, 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 from the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors 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 these funds 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.

Note 2 —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 months ended June 30, 2021 and the period from February 5, 2021 (inception) through June 30, 2021 are not necessarily indicative of the results that may be expected through December 31, 2021.

The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Current Report on Form 8-K and the final prospectus filed by the Company with the SEC on April 2, 2021 and March 24, 2021, respectively.

In April 2021, the Company identified an error in its accounting treatment for both its public and private warrants (Warrants) as presented in its audited balance sheet as of March 29, 2021 included in its Current Report on Form 8-K, filed April 2, 2021. The Warrants were reflected as a component of equity as opposed to liabilities on the balance sheet. Pursuant to FASB ASC Topic 250, Accounting Changes and Error Corrections, and Staff Accounting Bulletin 99, “Materiality”) (“SAB 99”) issued by the SEC, the Company determined the impact of the error was immaterial. The following balance sheet items were impacted from the error correction as of April 2, 2021: a $22.3 million increase to derivative liabilities and offsetting decrease to Class A ordinary shares subject to possible redemption; an increase of approximately $697,000 in additional paid-in capital; and an increase of approximately $697,000 in accumulated deficit.

Use of Estimates

The preparation of 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 financial statements and the reported amounts of income 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 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 significantly from those estimates.

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, 2021.

Investments Held in Trust Account

The Trust Investments are presented on the 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 unaudited condensed statement of operations. The estimated fair values of the Trust Investments are determined using available market information.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage limit of $250,000. As of June 30, 2021, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

MSD ACQUISITION CORP.
NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

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

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 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 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 and forward purchase agreements, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815-40, “Derivatives and Hedging – Contracts in Entity’s Own Equity” (“ASC 815-40”). 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 11,500,000 Public Warrants and the 9,333,333 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 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 unaudited condensed statement of operations. The estimated fair value of the Public Warrants is measured at fair value using a Monte Carlo simulation. The estimated fair value of the Private Placement Warrants is measured at fair value using a Black-Scholes option pricing model. The determination of the fair value of the stock purchase warrants may be subject to change as more current information becomes available and accordingly the actual results could differ significantly.

The forward purchase agreement between the Company and a certain investor, providing for the investor to purchase up to $50,000,000 of units, with each unit consisting of one Class A ordinary share and one-fifth of one warrant to purchase one Class A ordinary share, at a purchase price of $10.00 per unit in a private placement concurrently with the closing of the initial Business Combination, is recognized as a derivative liability in accordance with ASC 815-40. Accordingly, the Company recognizes the instrument as a liability at fair value and with changes in fair value recognized in the Company’s unaudited condensed statement of operations. The fair value of the forward purchase agreement is determined as the estimated unit value less the net present value of the forward purchase agreement.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

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 were 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 were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged to shareholders’ equity 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 480. 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, at June 30, 2021, 52,351,594 shares of Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s unaudited condensed balance sheet.

Income Taxes

The Company complies with the accounting and reporting requirements of FASB ASC Topic 740, “Income Taxes,” which 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, 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.

There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statement. 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’s condensed statements of operations include a presentation of net income (loss) per share for Class A ordinary shares subject to possible redemption in a manner similar to the two-class method of net income (loss) per ordinary shares. Net income (loss) per ordinary shares, basic and diluted, for Class A ordinary shares is calculated by dividing the interest income earned on the Trust Account, less interest available to be withdrawn for the payment of taxes, by the weighted average number of Class A ordinary shares outstanding for the periods. Net income (loss) per ordinary shares, basic and diluted, for Class B ordinary shares is calculated by dividing the net income (loss), adjusted for income attributable to Class A ordinary shares, by the weighted average number of Class B ordinary shares outstanding for the periods. Class B ordinary shares include the Founder Shares as these ordinary shares do not have any redemption features and do not participate in the income earned on the Trust Account.

The calculation of diluted net income (loss) per ordinary shares does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, (ii) exercise of over-allotment and (iii) Private Placement since the exercise price of the warrants is in excess of the average ordinary shares price for the period and therefore the inclusion of such warrants would be anti-dilutive.

Recent Accounting Standards

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. The Company early adopted the ASU on February 5, 2021 (inception). Adoption of ASU 2020-06 did not impact the Company’s financial position, results of operations or cash flows.

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Note 3 — Initial Public Offering

On March 29, 2021, the Company consummated its Initial Public Offering of 57,500,000 Units, including 7,500,000 Over-Allotment Units, at $10.00 per Unit, generating gross proceeds of $575.0 million, and incurring offering costs of approximately $33 million, of which approximately $20.1 million was for deferred underwriting commissions.

Each unit had an offering price of $10.00 and consisted of one Class A ordinary share and one-fifth of one Public Warrant. Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 7).

MSD ACQUISITION CORP.
NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Note 4 — Private Placement

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 9,333,333 Private Placement Warrants, at a price of $1.50 per Private Placement Warrant with the Sponsor, generating gross proceeds of $14.0 million.

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 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 except as described below in Note 7 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.

Note 5 — Related Party Transactions

Founder Shares

On February 11, 2021, the Sponsor paid an aggregate of $25,000 for certain offering expenses on behalf of the Company in exchange for issuance of 14,375,000 Class B ordinary shares (the “Founder Shares”). The Sponsor agreed to forfeit up to an aggregate of 1,875,000 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent 20% of the Company’s issued and outstanding shares after the Initial Public Offering. On March 29, 2021, the underwriter fully exercised its over-allotment option; thus, these 1,875,000 Founder Shares were no longer subject to forfeiture.

The Initial Shareholders agreed not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination or earlier if, subsequent to the initial Business Combination, the closing price of the Class A ordinary share equals or exceeds $12.00 per share (as adjusted for share sub-divisions, capitalization of shares, share dividends, rights issuances, subdivisions 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, and (B) 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 Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

Forward Purchase Agreement

On March 24, 2021, the Company entered into a forward purchase agreement (the “Forward Purchase Agreement”) with the certain investor (the “Forward Purchase Investor”), pursuant to which the Forward Purchase Investor agreed to purchase up to $50,000,000 of forward purchase units. Each forward purchase unit (“Forward Purchase Unit”) will consist of one Class A ordinary share (the “Forward Purchase Shares”) and one-fifth of one warrant to purchase one Class A ordinary share (the “Forward Purchase Warrants”), and will be sold at a purchase price of $10.00 per Forward Purchase Unit in a private placement concurrently with the closing of the initial Business Combination. The obligations of the Forward Purchase Investor under the Forward Purchase Agreement do not depend on whether any Class A ordinary shares held by Public Shareholders are redeemed by the Company and the amount of Forward Purchase Units sold pursuant to the Forward Purchase Agreement will be subject to the Forward Purchase Investor’s sole discretion. The proceeds from the sale of the Forward Purchase Units may be used as part of the consideration to the sellers in the initial Business Combination, expenses in connection with the initial Business Combination or for working capital in the post-transaction company. The Forward Purchase Shares will generally be identical to the Class A ordinary shares included in the Units sold in the Initial Public Offering, except that they will be entitled to certain registration rights. The Forward Purchase Warrants will have the same terms as the Private Placement Warrants so long as they are held by MSD Partners or its permitted assignees and transferees.

Related Party Loans

On February 8, 2021, the Sponsor agreed to loan the Company up to $300,000 pursuant to a promissory note (the “Note”). The Note was non-interest bearing, unsecured and due upon the closing of the Initial Public Offering. As of March 29, 2021, the Company borrowed approximately $192,000 under the Note. The Company repaid the Note in full on March 30, 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 may repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans may 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 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 $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 June 30, 2021, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

On March 24, 2021, the Company entered into an agreement that provided that, commencing on the date that the Company’s securities were first listed on Nasdaq through the earlier of consummation of the initial Business Combination or the liquidation, the Company agreed to pay the Sponsor up to $10,000 per month for office space, administrative support and other services provided to members of the Company’s management team.

In addition, the Sponsor, officers and directors, or any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. The audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, officers or directors, or the Company’s or their affiliates. Any such payments prior to an initial Business Combination will be made from funds held outside the Trust Account.

Note 6 — Commitments and Contingencies

Registration and Shareholder Rights

The holders of the 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 the effective date of the Initial Public Offering. The holders of these securities were entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a 45-day option from the date of this prospectus to purchase up to 7,500,000 additional Units at the Initial Public Offering price less the underwriting discounts and commissions. On March 29, 2021, the underwriters fully exercised its over-allotment option.

The underwriters were entitled to an underwriting discount of $0.20 per unit, or $11.5 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per unit, or approximately $20.1 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.

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 condensed financial statement. The condensed financial statement does not include any adjustments that might result from the outcome of this uncertainty.

Note 7 — Shareholders’ Equity

Preference Shares — The Company is authorized to issue 5,000,000 preference shares with a par value of $0.0001 per share. As of June 30, 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. Holders of the Company’s Class A ordinary shares are entitled to one vote for each share. As of June 30, 2021, there were 5,148,406 Class A ordinary shares issued and outstanding, excluding 52,351,594 Class A ordinary shares subject to possible redemption.

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 February 11, 2021, the Company issued 14,375,000 Class B ordinary shares. Of these, up to 1,875,000 Class B ordinary shares were subject to forfeiture to the Company by the Initial Shareholders for no consideration to the extent that the underwriters’ over-allotment option was not exercised in full or in part, so that the Class B ordinary shares would collectively represent 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. On March 29, 2021, the underwriter fully exercised its over-allotment option; thus, these 1,875,000 Class B ordinary shares were no longer 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 and holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the shareholders except as required by law; provided that only holders of Class B ordinary shares will have the right to vote on the appointment of directors prior to or in connection with the completion of the initial Business Combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of 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. 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 Founder Shares will equal, in the aggregate, on an as-converted basis, 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 upon conversion of Working Capital Loans; provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

Note 8 — Warrants

As of June 30, 2021, there were 20,833,333 warrants outstanding. Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants were 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 and (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 Class A ordinary shares issuable upon exercise of the Public Warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permit holders to exercise their warrants on a cashless basis under certain circumstances). 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 commercially reasonable efforts to file with the SEC a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants and to maintain a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60^th 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 Class A ordinary shares 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” and, in the event the Company so elects, the Company 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 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 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, the $18.00 per share redemption trigger price 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 will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price See “— 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” (as described below).

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except (i) 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, (ii) except as described below, the Private Placement Warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees and (iii) the Sponsor or its permitted transferees will have the option to exercise the Private Placement Warrants on a cashless basis and have certain registration rights. 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 in all redemption scenarios 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 call the outstanding warrants for redemption (except as described herein with respect to the Private Placement Warrants):

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

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

Once the warrants become exercisable, the Company may call the outstanding warrants for redemption (except as described herein with respect to the Private Placement 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 on a cashless basis in connection with this redemption feature for more than 0.361 Class A ordinary shares per warrant (subject to adjustment).

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 9 — Fair Value Measurements

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2021 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value.

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. The estimated fair value of Public Warrants for $12,995,000 was transferred from a Level 3 fair value measurement to a Level 1 measurement, when the Public Warrants were separately listed and traded in May 2021. There were no other transfers to/from Levels 1, 2, and 3 during the three and for the period from  February 5, 2021 (inception) through June 30, 2021.

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

For periods where no observable traded price is available, the fair value of the Public Warrants is measured at fair value using a Monte Carlo simulation. The estimated fair value of the Private Placement Warrants is measured at fair value using a Black-Scholes option pricing model. The fair value of the forward purchase agreement is determined as the estimated unit value less the net present value of the forward purchase agreement. The estimated fair value of the Public Warrants and the Private Placement Warrants, prior to the Public Warrants being traded in an active market, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation and a Black-Scholes 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 warrants based on implied volatility from the Company’s traded warrants, once the Public Warrants were traded in active market, and from historical volatility of select peer company’s shares 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. Any changes in these assumptions can change the valuation significantly.

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

The change in the fair value of derivative liabilities, measured using Level 3 inputs, for the three months ended June 30, 2021 and for the period from February 5, 2021 (inception) through June 30, 2021 is summarized as follows:
