PRELIMINARY PROXY STATEMENT – SUBJECT TO COMPLETION, DATED OCTOBER 28, 2022

LETTER TO STOCKHOLDERS OF

FORTISTAR SUSTAINABLE SOLUTIONS CORP.

One North Lexington Avenue

White Plains, NY 10601

To the Stockholders of Fortistar Sustainable Solutions Corp.:

You are cordially invited to attend a special meeting (the “Special Meeting”) of Fortistar Sustainable Solutions Corp., a Delaware corporation (“FSSI”, “we”, “us”, “our” or the “Company”), to be held on [•], 2022, at [•] [a.m./p.m.], Eastern Time, or at such other time and on such other date to which the meeting may be adjourned or postponed. The Special Meeting will be held via the Internet and will be a completely virtual meeting of stockholders. The virtual meeting format allows attendance from any location in the world. You can attend the Special Meeting, vote, and submit questions via live audio webcast by visiting https://www.cstproxy.com/fortistarssc/2022 and entering the control number found on your proxy card, voting instruction form or notice included in the proxy materials. We recommend logging in at least fifteen minutes before the meeting to ensure that you are logged in when the meeting starts. Online check-in will start shortly before the Special Meeting. The accompanying proxy statement is dated [•], 2022, and is first being mailed to stockholders of the Company on or about that date.

Even if you are planning on attending the Special Meeting online, please promptly submit your proxy vote by completing, dating, signing and returning the enclosed proxy, so that your shares will be represented at the Special Meeting. It is strongly recommended that you complete and return your proxy card before the Special Meeting date to ensure that your shares will be represented at the Special Meeting. Instructions on how to vote your shares are in the accompanying proxy statement and the other proxy materials you received for the Special Meeting.

The Special Meeting is being held to consider and vote upon the following proposals:

Proposal No. 1 – The Charter Amendment Proposal – to amend the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) by adopting the second amended and restated certificate of incorporation reflecting the changes marked on the document, in the form set forth in Annex A of the accompanying proxy statement (the “Second Amended and Restated Charter”), to amend the date by which the Company must cease all operations except for the purpose of winding up if it fails to complete a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”) from January 29, 2023 (the “Original Termination Date”) to the later of (x) [•], 2022 or (y) the date of effectiveness of the Second Amended and Restated Charter (the “Amended Termination Date”) (the “Charter Amendment Proposal”);

Proposal No. 2 – The Trust Amendment Proposal – to amend the Investment Management Trust Agreement, dated January 29, 2021 (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as trustee (“Continental”), pursuant to an amendment to the Trust Agreement in the form set forth in Annex B of the accompanying proxy statement (the “Trust Amendment”) to change the date on which Continental must commence liquidation of the trust account established in connection with the Company’s initial public offering (the “IPO”) (the “Trust Account”) to the Amended Termination Date (the “Trust Amendment Proposal”); and

Proposal No. 3 – The Adjournment Proposal – to adjourn the Special Meeting to a later date or dates or sine die, if necessary, either (x) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) and Class B common stock, par value $0.0001 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal or (y) if the Company’s board of directors (the “Board”) determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal (the “Adjournment Proposal” and, together with the Charter Amendment Proposal and the Trust Amendment Proposal, the “Proposals”).

TABLE OF CONTENTS

The Company will transact no other business at the Special Meeting, except such business as may properly come before the Special Meeting or any adjournments or postponements thereof.

Each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross-conditioned on the approval of each other. Each of the Proposals is more fully described in the accompanying proxy statement, which you are encouraged to read carefully.

The Charter currently provides that the Company has until the Original Termination Date to complete its initial Business Combination and, if the Company does not complete an initial Business Combination by the Original Termination Date, it 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 subject to lawfully available funds therefor, redeem 100% of the shares of Class A Common Stock issued in the IPO (the “Public Shares”) in consideration of a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Company to pay taxes (less up to $100,000 of such interest to pay dissolution expenses), divided by the total number of the then-outstanding Public Shares (such redemption, the “Mandatory Redemption”), which Mandatory Redemption will completely extinguish the rights of the holders of Public Shares (the “Public Stockholders”) as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, and subject to the approval of Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the General Corporation Law of the State of Delaware (as amended from time to time, the “DGCL”) to provide for claims of creditors and the requirements of other applicable law.

If the Charter Amendment Proposal is approved, and because the Company will not be able to complete an initial Business Combination by the Amended Termination Date, the Company will (i) immediately after the Special Meeting, cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, complete the Mandatory Redemption; and (iii) as promptly as reasonably possible following such Mandatory Redemption, and subject to the approval of the Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law.

If the Trust Amendment Proposal is approved, Continental shall commence liquidation of the Trust Account only after and promptly after (x) its receipt of the applicable instruction letter delivered by the Company in connection with either a closing of an initial Business Combination or the Company’s inability to effect an initial Business Combination within the time frame specified in the Charter or (y) upon the Amended Termination Date, if the aforementioned termination letter has not been received by Continental prior to such date.

The Board believes that the current provisions of the Charter and the existing Trust Agreement described above were included to protect the Company’s stockholders from having to sustain their investment for an unreasonably long period if the Company were unable to find a suitable initial Business Combination target in the timeframe contemplated by the Charter. However, even though the Board has determined that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, in the absence of the affirmative vote of at least 65% of the outstanding shares of Class A Common Stock and Class B Common Stock to commence the voluntary liquidation of the Company prior to the consummation of a Business Combination, the Company is not permitted by the Charter and the existing Trust Agreement to return the funds in the Trust Account to the Public Stockholders by way of liquidating the Trust Account until after the Original Termination Date, and the Public Stockholders may only exercise their redemption rights in connection with a stockholder vote on a proposed Business Combination or upon the approval of an amendment to any provision of the Charter relating to stockholders’ rights or pre-initial Business Combination activity.

TABLE OF CONTENTS

stock after December 31, 2022 (the “Excise Tax”). The Excise Tax is imposed on the fair market value of the repurchased stock, with certain exceptions. Because we are a Delaware corporation and our securities trade on NASDAQ, we are a “covered corporation” within the meaning of the IRA. While not free from doubt, absent any further guidance, there is significant risk that the Excise Tax will apply to any redemptions of our Public Shares after December 31, 2022, including redemptions made if we are unable to consummate a Business Combination by or before the Original Termination Date. The application of the Excise Tax to any redemptions we make after December 31, 2022 could potentially reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive.

The purpose of the Charter Amendment Proposal and the Trust Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Company will be obligated to redeem all issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The securities offered in the IPO were units (the “Units”) comprised of one share of Class A Common Stock and one-half of one redeemable warrant (a “Public Warrant”). The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from the NASDAQ Capital Market (“NASDAQ”) as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

For further details about the reasons for the Charter Amendment Proposal and the Trust Amendment Proposal, see the sections titled “Proposal No. 1 — The Charter Amendment Proposal — Reasons for the Charter Amendment Proposal” and “Proposal No. 2 — The Trust Amendment Proposal — Reasons for the Trust Amendment Proposal,” respectively, of this proxy statement.

The Company reserves the right to move to adjourn the Special Meeting sine die in the event that the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal. In that event, at the Special Meeting the Company will ask its stockholders to vote only upon the Adjournment Proposal and not on the Charter Amendment Proposal and/or the Trust Amendment Proposal.

The Board has fixed the close of business on [•], 2022 (the “Record Date”) as the record date for determining the Company’s stockholders entitled to receive notice of, and vote at, the Special Meeting and any adjournment thereof. Only holders of record of Common Stock on the Record Date are entitled to have their votes counted at the Special Meeting or any adjournment thereof.

Pursuant to the Charter, a Public Stockholder may request that the Company redeem all or a portion of its Public Shares for cash if the Charter Amendment Proposal is approved. Notwithstanding the foregoing, if the Charter Amendment Proposal is approved, and because the Company will not be able to complete an initial Business Combination by the Amended Termination Date, the Company will be obligated to redeem all Public Shares as promptly as reasonably possible after the Amended Termination Date. THEREFORE, NO ACTION IS REQUIRED ON YOUR PART IN ORDER TO REDEEM YOUR SHARES. AS A RESULT OF APPROVING THE CHARTER AMENDMENT PROPOSAL AND THE TRUST AMENDMENT PROPOSAL, YOUR SHARES WILL BE AUTOMATICALLY REDEEMED AS PART OF THE MANDATORY REDEMPTION.

receiving approximately $[•] more per share than if the shares of Class A Common Stock were sold in the open market. The Company cannot assure stockholders that they will be able to sell their shares of Class A Common Stock in the open market, even if the market price per share is lower than the redemption price stated above, as there may not be sufficient liquidity in its shares when such stockholders wish to sell their shares.

The approval of the Charter Amendment Proposal and the Trust Amendment Proposal each require the affirmative vote of the holders of at least sixty-five percent (65%) of all outstanding shares of Common Stock, voting together as a single class.

The approval of the Adjournment Proposal requires the affirmative vote of the holders of a majority of the then-outstanding shares of Common Stock present at the Special Meeting and entitled to vote thereon, voting together as a single class. The Adjournment Proposal will only be put forth for a vote if either there are not sufficient votes to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal at the Special Meeting or the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal.

After careful consideration of all relevant factors, including, but not limited to, the IRA and the Excise Tax, the time value of money and the conclusion that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, the Board has determined that the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal are in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” each of the proposals.

Your vote is very important. Whether or not you plan to attend the Special Meeting, please vote as soon as possible by following the instructions in the accompanying proxy statement to make sure that your shares are represented and voted at the Special Meeting. Submitting a proxy now will NOT prevent you from being able to attend and vote during the Special Meeting. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that the shares you beneficially own are represented and voted at the Special Meeting. In this regard, you must provide the record holder of your shares with instructions on how to vote your shares or, if you wish to attend the Special Meeting and vote in person, you will need to obtain a legal proxy from your bank, broker or nominee authorizing you to vote these shares and email a copy (a legible photograph is sufficient) of your proxy to proxy@continentalstock.com no later than 72 hours prior to the Special Meeting. If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted FOR each of the proposals presented at the Special Meeting. If you fail to return your proxy card and do not vote in person or by proxy at the Special Meeting, your shares (i) will not be counted for the purposes of determining whether a quorum is present at the Special Meeting or whether the Charter Amendment Proposal or the Adjournment Proposal (as the case may be) is approved by the requisite votes; and (ii) will have the effect of a vote “AGAINST” the Trust Amendment Proposal at the Special Meeting.

Enclosed is the Notice of Special Meeting and accompanying proxy statement containing detailed information about the Special Meeting, the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal. Whether or not you plan to attend the Special Meeting, the Company urges you to read this material carefully and vote your shares.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS OF

FORTISTAR SUSTAINABLE SOLUTIONS CORP.

TO BE HELD ON

[•], 2022

To the Stockholders of Fortistar Sustainable Solutions Corp.:

NOTICE IS HEREBY GIVEN that a special meeting of the stockholders of Fortistar Sustainable Solutions Corp., a Delaware corporation (the “Company”), will be held on [•], 2022, at [•] [a.m./p.m.], Eastern Time (the “Special Meeting”), or at such other time and on such other date to which the meeting may be adjourned or postponed. The Special Meeting will be held via the Internet and will be a completely virtual meeting of stockholders. The virtual meeting format allows attendance from any location in the world. You can attend the Special Meeting, vote, and submit questions via live audio webcast by visiting https://www.cstproxy.com/fortistarssc/2022 and entering the control number found on your proxy card, voting instruction form or notice included in the proxy materials

You are cordially invited to attend the Special Meeting that will be held for the purpose of considering and voting on (i) a charter amendment proposal to amend and restate the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) by adopting the second amended and restated certificate of incorporation in the form reflecting the changes marked on the document set forth in Annex A of the accompanying proxy statement (the “Second Amended and Restated Charter”) to amend the date by which the Company must cease all operations except for the purpose of winding up if it fails to complete a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”) from January 29, 2023 (the “Original Termination Date”) to the later of (x) [•], 2022 or (y) the date of the effectiveness of the Second Amended and Restated Charter (the “Amended Termination Date”) (the “Charter Amendment Proposal”); (ii) a trust amendment proposal to amend the Investment Management Trust Agreement, dated January 29, 2021 (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as trustee (“Continental”), pursuant to an amendment to the Trust Agreement in the form set forth in Annex B of the accompanying proxy statement (the “Trust Amendment”) to change the date on which Continental must commence liquidation of the trust account established in connection with the Company’s initial public offering (the “IPO”) (the “Trust Account”) to the Amended Termination Date (the “Trust Amendment Proposal”) and (iii) an adjournment proposal to adjourn the Special Meeting to a later date or dates or sine die, if necessary, either (x) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) and Class B common stock, par value $0.0001 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal or (y) if the Company’s board of directors (the “Board”) determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal (the “Adjournment Proposal” and, together with the Charter Amendment Proposal and the Trust Amendment Proposal, the “Proposals”), more fully described in the accompanying proxy statement, which is dated [•], 2022 and is first being mailed to stockholders on or about that date.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022 (H.R. 5376) (the “IRA”), which, among other things, imposes a 1% excise tax on any domestic corporation that repurchases its stock after December 31, 2022 (the “Excise Tax”). The Excise Tax is imposed on the fair market value of the repurchased stock, with certain exceptions. Because we are a Delaware corporation and our securities trade on NASDAQ, we are a “covered corporation” within the meaning of the IRA. While not free from doubt, absent any further guidance, there is significant risk that the Excise Tax will apply to any redemptions of our Public Shares after December 31, 2022, including redemptions made if we are unable to consummate a Business Combination by or before the Original Termination Date. The application of the Excise Tax to any redemptions we make after December 31, 2022 could potentially reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive.

business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The securities offered in the IPO were units (the “Units”) comprised of one share of Class A Common Stock and one-half of one redeemable warrant (a “Public Warrant”). The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

Each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross-conditioned on the approval of each other. The Adjournment Proposal is not conditioned upon the approval of any other proposal. If, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal, the Company may move to adjourn the Special Meeting to such later date or dates to permit further solicitation and vote of proxies. The Company also reserves the right to move to adjourn the Special Meeting sine die in the event that the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal. In those events, at the Special Meeting the Company will ask its stockholders to vote only upon the Adjournment Proposal and not on the Charter Amendment Proposal and/or the Trust Amendment Proposal. If the Charter Amendment Proposal and the Trust Amendment Proposal are approved at the Special Meeting, the Adjournment Proposal will not be presented. After careful consideration of all relevant factors, including, but not limited to, the IRA and the Excise Tax, the time value of money and the conclusion that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, the Board has determined that the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal are in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” each of the proposals.

On the Record Date, the redemption price per share was approximately $[•] (which is expected to be the same approximate amount at the time of the Mandatory Redemption), based on the aggregate amount on deposit in the Trust Account of approximately $[•] as of the Record Date, divided by the total number of then outstanding Public Shares. The closing price of the Class A Common Stock on NASDAQ on the Record Date was $[•]. Accordingly, if the market price of the Class A Common Stock were to remain the same until the date of the Special Meeting, adopting the Second Amended and Restated Charter would result in a Public Stockholder receiving approximately $[•] more per share than if the shares of Class A Common Stock were sold in the open market. The Company cannot assure stockholders that they will be able to sell their shares of Class A Common Stock in the open market, even if the market price per share is lower than the redemption price stated above, as there may not be sufficient liquidity in its shares when such stockholders wish to sell their shares.

TABLE OF CONTENTS

The approval of the Charter Amendment Proposal is a condition to its implementation.

If the Charter Amendment Proposal is not approved or implemented, and a Business Combination is not completed on or before January 29, 2023, 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 complete the Mandatory Redemption, which redemption may be subject to the Excise Tax that could reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive, and such redemption will completely extinguish the rights of the holders of Public Shares (the “Public Stockholders”) as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following the Mandatory Redemption, and subject to the approval of Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law.

Record holders of Common Stock at the close of business on the Record Date are entitled to vote or have their votes cast at the Special Meeting. On the Record Date, there were 25,875,000 issued and outstanding shares of Class A Common Stock and 6,468,750 issued and outstanding shares of Class B Common Stock. Voting on all resolutions at the Special Meeting will be conducted by way of a poll rather than on a show of hands. On a poll, votes are counted according to the number of shares registered in each stockholder’s name which are voted, with each share of Common Stock carrying one vote.

As of the date of the proxy statement, FSSC Sponsor LLC (the “Sponsor”) and our independent directors hold 20% of the issued and outstanding shares of Common Stock, including [•] Public Shares purchased as part of the Units sold in the IPO. In addition to these shares, (i) approval of the Charter Amendment Proposal will require the affirmative vote of at least 14,613,388 shares of Common Stock held by the Public Stockholders (or approximately 56.3% of the Class A Common Stock); (ii) approval of the Trust Amendment Proposal will require the affirmative vote of at least 14,613,388 shares of Common Stock held by the Public Stockholders (or approximately 56.3% of the Class A Common Stock); and (iii) approval of the Adjournment Proposal will require the affirmative vote of at least 9,744,126 shares of Common Stock held by the Public Stockholders (or approximately 37.5% of the Class A Common Stock) if all shares of Common Stock are represented at the Special Meeting and cast votes, and the affirmative vote of at least 1,628,689 shares of Common Stock held by the Public Stockholders (or approximately 6% of the Class A Common Stock) if only such shares as are required to establish a quorum are represented at the Special Meeting and cast votes.

The Sponsor and the Company’s directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any shares of Common Stock held by it or them, as applicable, if the Company fails to complete an initial Business Combination, although they will be entitled to liquidating distributions from the Trust Account with respect to any shares of Class A Common Stock they hold if the Company fails to complete its initial Business Combination by the applicable deadline. The Sponsor and the Company’s directors and officers intend to vote in favor of each of the proposals at the Special Meeting.

If the Company liquidates, the Sponsor has agreed that it will be liable to us if, and to the extent, any claims by a third party (other than our independent auditors) for services rendered or products sold to us, or a prospective target business with which we have discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the assets in the Trust Account, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under our indemnity of the underwriters of the IPO against certain

TABLE OF CONTENTS

liabilities, including liabilities under the Securities Act of 1933, as amended. 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 has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor’s only assets are securities of the Company and, therefore, the Sponsor may not be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties, including, without limitation, claims by vendors and prospective target businesses.

Enclosed is the proxy statement containing important information about the Special Meeting, the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal. Whether or not you plan to attend the Special Meeting, the Company urges you to read this material carefully and vote your shares.

If you have any questions or need assistance voting your shares of Common Stock, please contact Morrow Sodali, the Company’s proxy solicitor, by calling (800) 662-5200, or banks and brokers can call (203) 658-9400, or by emailing FSSI.info@investor.morrowsodali.com.

We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

•	our ability to complete a Business Combination or amend the date by which the Company must cease all operations if it fails to complete a Business Combination to the Amended Termination Date;

•	the Trust Account not being subject to claims of third parties;

•	the market price and liquidity of the shares of Class A Common Stock;

•	the per-share redemption price; and

•	the timing of the Mandatory Redemption and the our liquidation, dissolution and delisting.

While forward-looking statements reflect the Company’s good faith beliefs, they are not guarantees of future performance. The Company disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes after the date of this proxy statement, except as required by applicable law. For a further discussion of these and other factors that could cause the Company’s future results, performance or transactions to differ significantly from those expressed in any forward-looking statement, please see the section titled “Risk Factors” in the Company’s final prospectus, as filed with the Securities and Exchange Commission (the “SEC”) on January 28, 2021 and in other reports filed by the Company with the SEC.

FSSI is a blank check company incorporated in Delaware on August 25, 2020. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. Following the closing of the IPO on January 29, 2021, including the full exercise of the underwriters’ over-allotment option, and the concurrent sale of warrants to our Sponsor (the “Private Placement Warrants”), an amount of $258,750,000 from the net proceeds from the IPO and the sale of Private Placement Warrants were placed in the Trust Account.

Like most blank check companies, the Charter provides for the return of the IPO proceeds held in trust to the Public Stockholders if there is no qualifying Business Combination(s) consummated within 24 months after the date of the closing of the IPO (i.e., by the Original Termination Date).

On August 16, 2022, President Biden signed into law the IRA, which, among other things, imposes a 1% excise tax on any domestic corporation that repurchases its stock after December 31, 2022. The Excise Tax is imposed on the fair market value of the repurchased stock, with certain exceptions. Because we are a Delaware corporation and our securities trade on NASDAQ, we are a “covered corporation” within the meaning of the IRA. While not free from doubt, absent any further guidance, there is significant risk that the Excise Tax will apply to any redemptions of our Public Shares after December 31, 2022, including redemptions made if we are unable to consummate a Business Combination by or before the Original Termination Date. The application of the Excise Tax to any redemptions we make after December 31, 2022 could potentially reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive.

The purpose of the Charter Amendment Proposal and the Trust Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Company will be obligated to redeem all issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

TABLE OF CONTENTS

Charter Amendment Proposal and the Trust Amendment Proposal are in the best interests of the Company and its stockholders. On this basis, we believe that it is in the best interests of our stockholders to amend and restate the Charter and the Trust Agreement to change the Original Termination Date to the Amended Termination Date and is therefore holding this Special Meeting.

Q:	What are the specific proposals on which I am being asked to vote at the Special Meeting?

A:	FSSI stockholders are being asked to consider and vote on the following proposals:

Proposal No. 1 — Charter Amendment Proposal — to amend and restate the Company’s Charter by adopting the Second Amended and Restated Charter reflecting the changes marked on the document in the form set forth in Annex A of this proxy statement to change the date by which the Company must cease all operations except for the purpose of winding up if it fails to complete a Business Combination, from the Original Termination Date to the Amended Termination Date;

Proposal No. 2 — Trust Amendment Proposal — to amend the Trust Agreement, pursuant to an amendment to the Trust Agreement in the form set forth in Annex B of this proxy statement, to change the date on which Continental must commence liquidation of the Trust Account to the Amended Termination Date; and

Proposal No. 3 — Adjournment Proposal — to adjourn the Special Meeting to a later date or dates or sine die, if necessary, either (x) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal or (y) if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal.

Each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross-conditioned on the approval of each other. The Adjournment Proposal is not conditioned upon the approval of any other proposal. For more information, please see “Proposal No. 1 — The Charter Amendment Proposal,” “Proposal No. 2 — The Trust Amendment Proposal” and “Proposal No. 3 — The Adjournment Proposal.”

After careful consideration, the Board has determined that the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal are in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” each of the proposals.

The existence of financial and personal interests of our directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of the Company and its stockholders and what may be best for a director’s personal interests when determining to recommend that stockholders vote for the proposals. See the sections titled “Proposal No. 1 — The Charter Amendment Proposal —

TABLE OF CONTENTS

Interests of the Sponsor and the Company’s Officers and Directors,” “Proposal No. 2 — The Trust Amendment Proposal — Interests of the Sponsor and Company’s Officers and Directors,” and “Beneficial Ownership of Securities” for a further discussion of these considerations.

THE VOTE OF STOCKHOLDERS IS IMPORTANT. STOCKHOLDERS ARE URGED TO SUBMIT THEIR PROXIES AS SOON AS POSSIBLE AFTER CAREFULLY REVIEWING THIS PROXY STATEMENT.

Q:	Are the proposals conditioned on one another?

Q:	Why is the Company proposing the Charter Amendment Proposal and the Trust Amendment Proposal?

The Trust Agreement currently provides that Continental shall commence liquidation of the Trust Account only after and promptly after (x) its receipt of the applicable instruction letter delivered by the Company in connection with either a closing of an initial Business Combination or the Company’s inability to effect an initial Business Combination within the time frame specified in the Charter or (y) the Original Termination Date. If the Trust Amendment Proposal is approved, Continental shall commence liquidation of the Trust Account only after and promptly after (x) its receipt of the applicable instruction letter delivered by the Company in connection with either a closing of an initial Business Combination or the Company’s inability to effect an initial Business Combination within the time frame specified in the Charter or (y) upon the Amended Termination Date, if the aforementioned termination letter has not been received by Continental prior to such date.

TABLE OF CONTENTS

Stockholders may only exercise their redemption rights in connection with a stockholder vote on a proposed Business Combination or upon the approval of an amendment to any provision of the Charter relating to stockholders’ rights or pre-initial Business Combination activity.

The purpose of the Charter Amendment Proposal and the Trust Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Company will be obligated to redeem all issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The securities offered in the IPO were the Units comprised of one Public Share and one-half of one Public Warrant. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

In the event the Charter Amendment Proposal and the Trust Amendment Proposal are not approved or implemented and the Company is unable to complete a Business Combination on or before the Original Termination Date, the Company will dissolve and liquidate in accordance with the Charter.

Q:	What constitutes a quorum?

A quorum of our stockholders is necessary to hold a valid meeting. The presence at the virtual Special Meeting, in person or by proxy, of the holders of a majority of the issued and outstanding shares of Common Stock entitled to vote at the Special Meeting constitutes a quorum at the Special Meeting. Abstentions will be considered present for the purposes of establishing a quorum. The shares of the initial stockholders of the Company, including the Sponsor, (the “Initial Stockholders”), who own approximately 20% of the issued and outstanding shares of Common Stock as of the Record Date, will count towards this quorum. As a result, as of the Record Date, in addition to the shares of the Initial Stockholders, an additional 9,744,125 shares of Common Stock held by the Public Stockholders would be required to be present at the Special Meeting to achieve a quorum. Because all of the proposals to be voted on at the Special Meeting are “non-routine” matters, banks, brokers and other nominees will not have authority to vote on any proposals unless instructed, so the Company does not expect there to be any broker non-votes at the Special Meeting. If a quorum is not present within half an hour from the time appointed for the Special Meeting to commence or if during the Special Meeting a quorum ceases to be present, the Special

TABLE OF CONTENTS

Meeting will stand adjourned to the same day in the next week at the same time and place or to such other day, time and/or place as the Board may determine, and if at the adjourned meeting a quorum is not present within half an hour from the time appointed for the meeting to commence, the stockholders present will constitute a quorum.

Q:	What vote is required to approve the proposals presented at the Special Meeting?

A:	The approval of the Charter Amendment Proposal requires the affirmative vote of the holders of at least 65% of all then outstanding shares of Class A Common Stock and Class B Common Stock.

The approval of the Adjournment Proposal requires the affirmative vote of the holders of at least a majority of all then outstanding shares of Class A Common Stock and Class B Common Stock, voting as a single class, who are present in person or represented by proxy and entitled to vote thereon at the Special Meeting. The Adjournment Proposal will only be put forth for a vote if either (x) based upon the tabulated vote at the time of the Special Meeting there are not sufficient votes to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal at the Special Meeting or (y) if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal.

Q:	How will the Initial Stockholders vote?

On the Record Date, the Initial Stockholders owned and were entitled to vote an aggregate of [•] shares of Common Stock, representing approximately 20% of the Company’s issued and outstanding shares of Common Stock, and plan to vote in favor of each of the Charter Amendment Proposal, the Trust Amendment Proposal and, if presented, the Adjournment Proposal.

Q:	Why should I vote “FOR” the Charter Amendment Proposal and the Trust Amendment Proposal?

In the absence of the affirmative vote of at least 65% of the outstanding shares of Class A Common Stock and Class B Common Stock to commence the voluntary liquidation of the Company prior to the consummation of a Business Combination, the Company is not permitted by the Charter and the existing Trust Agreement to return the funds in the Trust Account to the Public Stockholders by way of liquidating the Trust Account until after the Original Termination Date, and the Public Stockholders may only exercise

their redemption rights in connection with a stockholder vote on a proposed Business Combination or upon the approval of an amendment to any provision of the Charter relating to stockholders’ rights or pre-initial Business Combination activity

The purpose of the Charter Amendment Proposal and the Trust Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Company will be obligated to redeem all issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The securities offered in the IPO were the Units comprised of one Public Share and one-half of one Public Warrant. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

After careful consideration of all relevant factors, including, but not limited to, the IRA and the Excise Tax, the time value of money and the conclusion that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, the Board has determined that the Charter Amendment Proposal and the Trust Amendment Proposal are in your best interests and recommends that you vote or give instruction to vote “FOR” the Charter Amendment Proposal and the Trust Amendment Proposal.

Q:	Why should I vote “FOR” the Adjournment Proposal?

If the Adjournment Proposal is not approved by the Company’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date or dates in the event that there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal.

The Company may also move to adjourn the Special Meeting sine die in the event that the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal. In that event, the Company will ask its stockholders to vote only upon the Adjournment Proposal and not on the Charter Amendment Proposal and/or the Trust Amendment Proposal.

If presented, the Board recommends that you vote in favor of the Adjournment Proposal.

TABLE OF CONTENTS

Q:	What if I do not want to vote “FOR” the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal?

A:	If you do not want the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal to be approved, you may “ABSTAIN,” not vote, or vote “AGAINST” such proposal.

If you attend the Special Meeting in person or by proxy, you may vote “AGAINST” the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal, and your shares of Common Stock will be counted for the purposes of determining whether the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal (as the case may be) is approved.

However, if you fail to return your proxy card, or if you fail to attend the Special Meeting in person or by proxy or do attend the Special Meeting in person or by proxy but “ABSTAIN” or otherwise fail to vote at the Special Meeting, (a) with respect to the Charter Amendment Proposal and the Adjournment Proposal, your shares of Common Stock will not be counted for the purposes of determining whether the Charter Amendment Proposal or the Adjournment Proposal (as the case may be) is approved and your shares of Common Stock which are not voted at the Special Meeting will have no effect on the outcome of such votes; and (b) with respect to the Trust Amendment Proposal, your shares of Common Stock will have the effect of a vote “AGAINST” the Trust Amendment Proposal at the Special Meeting.

If the Charter Amendment Proposal and the Trust Amendment Proposal are approved, the Adjournment Proposal will not be presented for a vote.

Q:	What happens if the Charter Amendment Proposal is not approved?

If, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal, the Company may put the Adjournment Proposal to a vote in order to seek additional time to obtain sufficient votes in support of the Charter Amendment Proposal. If the Adjournment Proposal is not approved by the Company’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date or dates in the event that there are insufficient votes from the holders of shares of Common Stock at the time of the Special Meeting to approve the Charter Amendment Proposal.

If the Charter Amendment Proposal is not approved at the Special Meeting or at any adjournment thereof or is not implemented, and a Business Combination is not completed on or before the Original Termination Date, then as contemplated by and in accordance with the Charter, 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 complete the Mandatory Redemption, which redemption may be subject to the Excise Tax and which could reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive, and such redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such Mandatory Redemption, and subject to the approval of Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law.

In addition, each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross- conditioned on the approval of each other.

Q:	If the Charter Amendment Proposal is approved, what happens next?

claims of creditors and the requirements of other applicable law. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

Q:	If I vote for or against the Charter Amendment Proposal, can I request that my shares be redeemed?

Whether you vote “FOR” or “AGAINST” the Charter Amendment Proposal, or do not vote at all, the Company will be obligated to complete redemption of all outstanding Public Shares, provided that the Charter Amendment Proposal is approved. Therefore, no action is required on your part in order to have your shares redeemed if the Charter Amendment Proposal is approved. Please see the question “How do I exercise my redemption rights?” below for further information.

Q:	May I change my vote after I have mailed my signed proxy card?

Yes. Stockholders of record may (i) send a later-dated, signed proxy card to Continental, the Transfer Agent, at the address set forth under the question “Who can help answer my questions?” below so that it is received no later than 48 hours before the time appointed for the holding of the Special Meeting (or, in the case of an adjournment, no later than 48 hours before the time appointed for the holding of the adjourned meeting); (ii) attend the Special Meeting virtually, revoke your proxy and vote; or (iii) revoke their proxy by sending a notice of revocation to the Board at the Company’s address at One North Lexington Avenue, White Plains, NY 10601, which must be received by the Board prior to the vote at the Special Meeting. However, if your shares are held in “street name” by your bank, broker or another nominee, you must contact your bank, broker or other nominee to change your vote.

Q:	How are votes counted?

A:	Voting on all resolutions at the Special Meeting will be conducted by way of a poll rather than on a show of hands. On a poll, votes are counted according to the number of shares registered in each stockholder’s name which are voted, with each share of Common Stock carrying one vote.

Votes will be counted by the inspector of election appointed for the Special Meeting, who will separately count “FOR” and “AGAINST” votes and “ABSTAIN”. Stockholders who attend the Special Meeting, either virtually or by proxy (or, if a corporation or other non-natural person, by sending their duly authorized representative or proxy), will be counted (and the number of shares of Common Stock held by such stockholders will be counted) for the purposes of determining whether a quorum is present at the Special Meeting.

At the Special Meeting, only those votes which are actually cast, either “FOR” or “AGAINST” the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal, will be counted for the purposes of determining whether the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal (as the case may be) is approved, and any shares of Common Stock which are not voted at the Special Meeting will have no effect on the outcome of such votes. Abstentions, while considered present for the purposes of establishing a quorum, (a) will not count as votes cast and will have no effect on the outcome of the vote on the Charter Amendment Proposal or the Adjournment Proposal; and (b) will have the effect of a vote “AGAINST” the Trust Amendment Proposal.

Q:	If my shares are held in “street name,” will my bank, broker or nominee automatically vote my shares for me?

If your shares are held in “street name” in a stock brokerage account or by a bank, broker or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, broker or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy card directly to the Company or by voting virtually online at the Special Meeting unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee. If you wish to attend the Special Meeting virtually and vote online you must obtain a legal proxy and e-mail a copy (a legible photograph is sufficient) of your proxy to Continental, the Transfer Agent, at proxy@continentalstock.com no later than 72 hours prior to the Special Meeting. Holders who e-mail a valid legal proxy will be issued a meeting control number that will allow them to register to attend and participate in the Special Meeting virtually.

TABLE OF CONTENTS

Under the rules of NASDAQ, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that NASDAQ determines to be “non-routine” without specific instructions from the beneficial owner. It is expected that all proposals to be voted on at the Special Meeting are “non-routine” matters and therefore, the Company does not expect there to be any broker non-votes at the Special Meeting.

If you hold your shares in “street name” and you do not instruct your bank, broker or other nominee on how to vote your shares, your bank, broker or other nominee will not vote your shares on the Charter Amendment Proposal, the Trust Amendment Proposal or the Adjournment Proposal. Accordingly, your bank, broker, or other nominee can vote your shares at the Special Meeting only if you provide instructions on how to vote. You should instruct your broker to vote your shares as soon as possible in accordance with directions you provide.

Q:	Does the Board recommend voting “FOR” the approval of the Charter Amendment Proposal and the Trust Amendment Proposal?

Yes. After careful consideration of all relevant factors, the Board has determined that the Charter Amendment Proposal and the Trust Amendment Proposal are in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” the Charter Amendment Proposal and the Trust Amendment Proposal.

Q:	What interests do the Company’s directors and officers have in the approval of the Charter Amendment Proposal?

Aside from their interests as stockholders, the Sponsor and the Company’s officers and directors have interests that differ from the interests of other stockholders generally. For more details, see the sections entitled “Proposal No. 1 — The Charter Amendment Proposal — Interests of the Sponsor and the Company’s Officers and Directors,” “Proposal No. 2 — The Trust Amendment Proposal — Interests of the Sponsor and the Company’s Officers and Directors,” and “Beneficial Ownership of Securities” of this proxy statement.

Q:	Do I have appraisal rights or dissenters’ rights if I object to the Charter Amendment Proposal?

A:	No. There are no appraisal rights or dissenters’ rights available to the Company’s stockholders in connection with the Charter Amendment Proposal.

Q:	What do I need to do now?

You are urged to read carefully and consider the information contained in this proxy statement and to consider how the Charter Amendment Proposal and the Trust Amendment Proposal will affect you as a stockholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement and on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank or other nominee, on the voting instruction form provided by the bank, broker or nominee.

Q:	How do I exercise my redemption rights?

Pursuant to the Charter, in connection with the approval of the Charter Amendment Proposal, the Company’s Public Stockholders may demand that the Company redeem their Public Shares for a full pro rata portion of the Trust Account, regardless of whether they vote for or against, or whether they abstain from voting on, the Charter Amendment Proposal.

TABLE OF CONTENTS

deposit in the Trust Account as of the Amended Termination Date, divided by the number of the issued and outstanding Public Shares. As of the close of business on the Amended Termination Date, all issued and outstanding Public Shares will be deemed cancelled and will represent only the right to receive the redemption amount. The redemption amount will be payable to the holders of these remaining Public Shares upon presentation of their respective stock certificates (if any) and other redemption forms or other delivery of their shares to the Transfer Agent. Beneficial owners of such Public Shares held in “street name,” however, will not need to take any action in order to receive the redemption amount. Upon the completion of the Mandatory Redemption, the Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any) will be extinguished.

The above paragraph assumes the Trust Amendment Proposal is also approved as each the Charter Amendment Proposal and the Trust Amendment Proposal is cross-condition on approval of each other.

For a discussion of certain material U.S. federal income tax considerations for stockholders with respect to the redemption, see “Certain Material U.S. Federal Income Tax Considerations for Stockholders for the Redemption of Public Shares.” The consequences of a redemption to any particular stockholder will depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the redemption, including the applicability and effect of U.S. federal, state, local and non-U.S. income and other tax laws in light of your particular circumstances.

Q:	What should I do if I receive more than one set of voting materials for the Special Meeting?

You may receive more than one set of voting materials for the Special Meeting, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast your vote with respect to all of your shares.

Q:	Who will solicit and pay the cost of soliciting proxies for the Special Meeting?

The Company will pay the cost of soliciting proxies for the Special Meeting. The Company has engaged Morrow Sodali LLC (“Morrow Sodali”) to assist in the solicitation of proxies for the Special Meeting. The Company will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of shares of Class A Common Stock for their expenses in forwarding soliciting materials to beneficial owners of shares of Class A Common Stock and in obtaining voting instructions from those owners. The directors, officers and employees of the Company may also solicit proxies by telephone, by facsimile, by mail or on the Internet. They will not be paid any additional amounts for soliciting proxies.

Q:	Who can help answer my questions?

A:	If you have questions about the proposals or if you need additional copies of this proxy statement or the enclosed proxy card you should contact:

SPECIAL MEETING OF STOCKHOLDERS

This proxy statement is being provided to the Company’s stockholders as part of a solicitation of proxies by the Board for use at the Special Meeting of the Company’s stockholders to be held on [•], 2022, and at any adjournment thereof. This proxy statement contains important information regarding the Special Meeting, the proposals on which you are being asked to vote and information you may find useful in determining how to vote and voting procedures.

This proxy statement is being first mailed on or about [•], 2022 to all stockholders of record of the Company as of the close of business on [•], 2022, the Record Date for the Special Meeting.

Date, Time and Place of Special Meeting

The Special Meeting will be held on [•], 2022 at [•] [a.m./p.m.], Eastern Time, or at such other time and on such other date to which the meeting may be adjourned or postponed.

TABLE OF CONTENTS

Proposal No. 3 — Adjournment Proposal — To adjourn the Special Meeting to a later date or dates or sine die, if necessary, either (x) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal or (y) if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal.

Each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross-conditioned on the approval of each other. The Adjournment Proposal is not conditioned upon the approval of any other proposal. If the Charter Amendment Proposal and the Trust Amendment Proposal are approved at the Special Meeting, the Adjournment Proposal will not be presented.

Voting Power; Record Date

As a stockholder of the Company, you have a right to vote on certain matters affecting the Company. The proposals that will be presented at the Special Meeting and upon which you are being asked to vote are summarized above and fully set forth in this proxy statement. You will be entitled to vote or direct votes to be cast at the Special Meeting if you owned shares of Common Stock at the close of business on [•], 2022, which is the Record Date for the Special Meeting. You are entitled to one vote for each share of Common Stock that you owned as of the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your bank, broker or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 32,343,750 issued and outstanding shares of Common Stock, of which 25,875,000 shares of Class A Common Stock are held by the Public Stockholders and 6,468,750‬ shares of Class B Common Stock are held by the Initial Stockholders.

Recommendation of the Board

THE BOARD RECOMMENDS

THAT YOU VOTE “FOR” EACH OF THESE PROPOSALS

Quorum

The presence, in person virtually or by proxy, of the holders of a majority of the issued and outstanding shares of Common Stock entitled to vote at the Special Meeting constitutes a quorum at the Special Meeting. Abstentions will be considered present for the purposes of establishing a quorum. The Initial Stockholders, who own approximately 20% of the issued and outstanding shares of Common Stock as of the Record Date, will count towards this quorum. As a result, as of the Record Date, in addition to the shares of the Initial Stockholders, an additional 9,744,125 shares of Common Stock held by the Public Stockholders would be required to be present at the Special Meeting to achieve a quorum.

Abstentions and Broker Non-Votes

Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Special Meeting and therefore (a) will have no effect on the outcome of the vote on the Charter Amendment Proposal or the Adjournment Proposal; and (b) will have the effect of a vote “AGAINST” the Trust Amendment Proposal at the Special Meeting.

Under NASDAQ rules, if a stockholder holds their shares in “street” name through a bank, broker or other nominee and the stockholder does not instruct their bank, broker or other nominee how to vote their shares on a proposal, the bank, broker or other nominee has the authority to vote the shares in its discretion on certain “routine” matters. However, banks, brokers and other nominees are not authorized to exercise their voting discretion on any “non-routine” matters. This can result in a “broker non-vote,” which occurs on a proposal when (i) a bank, broker or other nominee has discretionary authority to vote on one or more “routine” proposals to be voted on at a meeting of stockholder, (ii) there are one or more “non-routine” proposals to be voted on at the meeting for which the bank, broker or other nominee does not have authority to vote without instructions from the beneficial owner of the shares and (iii) the beneficial owner fails to provide the bank, broker or other nominee with voting instructions on a “non-routine” matter.

TABLE OF CONTENTS

We believe that all of the proposals to be voted on at the Special Meeting will be considered non-routine matters. As a result, if you hold your shares in street name, your bank, brokerage firm or other nominee cannot vote the shares you beneficially own on any of the proposals to be voted on at the Special Meeting without your instruction.

Because all of the proposals to be voted on at the Special Meeting are “non-routine” matters, banks, brokers and other nominees will not have authority to vote on any proposals unless instructed, so we do not expect there to be any broker non-votes at the Special Meeting.

Vote Required for Approval

The approval of the Charter Amendment Proposal requires the affirmative vote of the holders of at least 65% of all then outstanding shares of Class A Common Stock and Class B Common Stock.

Voting Your Shares

If you were a holder of record of shares of Common Stock as of the close of business on [•], 2022, the Record Date for the Special Meeting, you may vote with respect to the proposals by Internet at www.cstproxyvote.com, until 11:59 p.m., Eastern time, on [•], 2022 (have your proxy card available when you access the website), virtually at the Special Meeting, or by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. Your proxy card shows the number of shares of Common Stock that you own. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted.

There are three ways to vote your shares of Common Stock at the Special Meeting:

Voting by Mail. By signing and dating the proxy card and returning it in the enclosed prepaid and addressed envelope, you are authorizing the individual(s) named on the proxy card to vote your shares at the Special Meeting in the manner you indicate. You are encouraged to sign, date and return the proxy card even if you plan to attend the Special Meeting virtually so that your shares will be voted if you are unable to attend the Special Meeting virtually. If you receive more than one proxy card, it is an indication that your shares are held in multiple accounts. Please sign, date and return all proxy cards to ensure that all of your shares are voted. Votes submitted by mail must be received by [•] [a.m./p.m.], Eastern Time, on [•], 2022, being 48 hours before the time appointed for the holding of the Special Meeting (or, in the case of an adjournment, no later than 48 hours before the time appointed for the holding of the adjourned meeting). If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted FOR each of the proposals presented at the Special Meeting. If you fail to return your proxy card and do not vote in person or by proxy at the Special Meeting, your shares (i) will not be counted for the purposes of determining whether a quorum is present at the Special Meeting or whether the Charter Amendment Proposal or the Adjournment Proposal (as the case may be) is approved by the requisite votes; and (ii) will have the effect of a vote “AGAINST” the Trust Amendment Proposal at the Special Meeting.

Voting Electronically at the Special Meeting. You may attend, vote and examine the list of stockholders entitled to vote at the Special Meeting by visiting https://www.cstproxy.com/fortistarssc/2022 and entering the control number found on your proxy card, voting instruction form or notice included in the proxy materials. We recommend logging in at least fifteen minutes before the meeting to ensure that you are logged in when the meeting starts. Online check-in will start shortly before the Special Meeting. If you hold your shares in “street name,” which means your shares are held of record by a bank, broker or other nominee, you will need to contact the Transfer Agent for specific instructions on how to receive the control

number. The Transfer Agent can be contacted at the number or email address above. Please allow up to 72 hours prior to the meeting for processing your control number.

Revoking Your Proxy

If you are a stockholder of record and give a proxy, you may revoke it at any time before the Special Meeting or at the Special Meeting by doing any one of the following:

•

you may send a later-dated, signed proxy card to Continental, the Transfer Agent, which shall be received no later than 48 hours before the time appointed for the holding of the Special Meeting (or, in the case of an adjournment, no later than 48 hours before the time appointed for the holding of the adjourned meeting);

•	you may notify the Board in writing to Fortistar Sustainable Solutions Corp., 1345 Avenue of the Americas, White Plains, NY 10601, before the Special Meeting that you have revoked your proxy; or

•	you may attend the Special Meeting, revoke your proxy, and vote in person, as indicated above.

However, if your shares are held in “street name” by your bank, broker or another nominee, you must contact your bank, broker or other nominee to change your vote.

No Additional Matters

The Special Meeting has been called only to consider and vote on the approval of the Charter Amendment Proposal, the Trust Amendment Proposal and, if presented, the Adjournment Proposal. The Board does not know of any other matters to be presented at the Special Meeting. If any additional matters are properly presented at the Special Meeting, absence any express instructions to the contrary, the individual(s) named in the enclosed proxy card will have discretion to vote the shares they represent in accordance with their own judgment on such matters.

Who Can Answer Your Questions about Voting

If you are a stockholder and have any questions about how to vote or direct a vote in respect of your shares of Common Stock, you may call Morrow Sodali, our proxy solicitor, by calling (800) 662-5200 (toll-free), or banks and brokers can call (203) 658-9400, or by emailing FSSI.info@investor.morrowsodali.com.

Redemption Rights

Notwithstanding the foregoing, if the Charter Amendment Proposal is approved, and because the Company will not be able to complete an initial Business Combination by the Amended Termination Date, the Company will be obligated to complete the redemption of all the issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date. Therefore, no action is required on your part in order to redeem your shares. As a result of approving the Charter Amendment Proposal and the Trust Amendment Proposal, your shares will be automatically redeemed as part of the Mandatory Redemption at a per-share price, payable in cash, equal to the aggregate amount on deposit in the Trust Account as of the Amended Termination Date, divided by the number of the issued and outstanding Public Shares. As of the close of business on the Amended Termination Date, all issued and outstanding Public Shares will be deemed cancelled and will represent only the right to receive the redemption amount. The redemption amount will be payable to the holders of these Public Shares upon presentation of their respective stock certificates (if any) and other redemption forms or other delivery of their shares (and stock certificate (if any) and other redemption forms) to the Transfer Agent. Beneficial owners of such Public Shares held in “street name,” however, will not need to take any action in order to receive the redemption amount. Upon the completion of the Mandatory Redemption, the Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any) will be extinguished.

TABLE OF CONTENTS

In the event that each of the Charter Amendment Proposal and Trust Amendment Proposal are approved and implemented, a U.S. Holder’s receipt of cash for its Public Shares in connection with our liquidation is expected to be treated as a distribution to such holder in complete liquidation of the Company, with such distribution treated as a payment received in exchange for such Public Shares under Section 331 of the Code. The consequences of a redemption to any particular stockholder will depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the redemption, including the applicability and effect of U.S. federal, state, local and non-U.S. income and other tax laws in light of your particular circumstances.

Appraisal Rights and Dissenters’ Rights

There are no appraisal rights or dissenters’ rights available to the Company’s stockholders in connection with the Charter Amendment Proposal.

Proxy Solicitation Costs

The Company is soliciting proxies on behalf of the Board. This proxy solicitation is being made by mail, but also may be made by telephone or in person. The Company has engaged Morrow Sodalli to assist in the solicitation of proxies for the Special Meeting. The Company and its directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. The Company will ask banks, brokers and other institutions, nominees and fiduciaries to forward this proxy statement and the related proxy materials to their principals and to obtain their authority to execute proxies and voting instructions.

The Company will bear the entire cost of the proxy solicitation, including the preparation, assembly, printing, mailing and distribution of this proxy statement and the related proxy materials. The Company will pay Morrow Sodali a fee of $35,000, plus disbursements, reimburse Morrow Sodali for its reasonable out-of-pocket expenses and indemnify Morrow Sodali and its affiliates against certain claims, liabilities, losses, damages and expenses for its services as the Company’s proxy solicitor. The Company will reimburse brokerage firms and other custodians for their reasonable out-of-pocket expenses for forwarding this proxy statement and the related proxy materials to the Company’s stockholders. Directors, officers and employees of the Company who solicit proxies will not be paid any additional compensation for soliciting.

TABLE OF CONTENTS

PROPOSAL NO. 1 — THE CHARTER AMENDMENT PROPOSAL

Overview

The Company is proposing to amend and restate its Charter to change the date by which it has to consummate a Business Combination from the Original Termination Date to the Amended Termination Date.

On the Record Date, the redemption price per share was approximately $[•] (which is expected to be the same approximate amount two business days prior to the Special Meeting), based on the aggregate amount on deposit in the Trust Account of approximately $[•] as of the Record Date, divided by the total number of then outstanding Public Shares. The closing price of the shares of Class A Common Stock on NASDAQ on the Record Date was $[•]. Accordingly, if the market price of the shares of Class A Common Stock were to remain the same until the date of the Special Meeting, adopting the Second Amended and Restated Charter would result in a Public Stockholder receiving approximately $[•] more per share than if the shares were sold in the open market. The Company cannot assure stockholders that they will be able to sell their shares of Class A Common Stock in the open market, even if the market price per share is lower than the redemption price stated above, as there may not be sufficient liquidity in its shares when such stockholders wish to sell their shares.

Reasons for the Charter Amendment Proposal

FSSI is a blank check company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

The Company’s objective is to identify and complete a Business Combination by capitalizing on a combination of Sponsor’s relationships, knowledge and experience across industries can effect a positive transformation or augmentation of an existing business. After the closing of the IPO in January 2021, and consistent with the Company’s business purpose, the Board and the Company’s management commenced an active search for potential Business Combination targets, leveraging the Company’s and the Sponsor’s network of relationships and intimate knowledge of the private company marketplace.

As of the date of this proxy statement, the Company’s management has reviewed more than 100 potential targets operating in a wide spectrum of sectors including Energy, Technology and Sustainability, among others, and submitted multiple letters of intent in connection with the Company’s search for suitable targets.

As of the date of this proxy statement, the Company has not entered into a successful agreement to effectuate a Business Combination with any of the potential targets that it has reviewed due to a variety of reasons, including, among other things: (i) the parties’ inability to reach an agreement on valuation; (ii) the Company’s preliminary assessment of the relevant target company’s business model, customer concentration, competitive landscape and corresponding risks to future financial performance; (iii) the Company’s preliminary assessment of the relevant target company’s ability to execute its business and financial plans and scale its business; and (iv) alternative options available to potential targets, such as pursuing a traditional initial public offering or waiting for the capital markets to improve before pursuing a listing.

In particular, through its efforts to find a suitable target for a Business Combination, the Company’s management has encountered material changes in the market valuations of public company transactions since the IPO, creating divergent expectations of valuation between SPACs like the Company and stockholders of the privately owned businesses that may be interested in pursuing a Business Combination. The Board believes such a divergence in expectations will remain the trend in the near to medium term such that the Company will not be able to identify, agree upon and consummate a Business Combination with a suitable target that meets the Company’s criteria for a Business Combination at an acceptable valuation by or before the Original Termination Date. Changes in the regulatory landscape have further affected the Company’s prospects for consummating a Business Combination, including the Excise Tax included in the Inflation Reduction Act of 2022, the SEC’s proposed rules relating to, among other items, enhancing disclosure in Business Combination transactions involving SPACs and private operating companies and increasing the potential liability of certain participants in proposed Business Combination transactions. The Board considers that the SEC’s proposed rules, if adopted, whether in the form proposed or in revised form, may materially increase the time required to negotiate and complete an initial Business Combination and could further impair the Company’s ability to complete an initial Business Combination by or before the Original Termination Date.

TABLE OF CONTENTS

Original Termination Date, it 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 complete the Mandatory Redemption, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such Mandatory Redemption, and subject to the approval of Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law.

The purpose of the Charter Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Company will be obligated to redeem all issued and outstanding Public Shares as promptly as reasonably possible but not more than ten business days after the Amended Termination Date which will allow the Company to return the funds to its Public Stockholders in calendar year 2022 before the Excise Tax begins to apply to stock repurchases and redemptions in 2023, to enable these stockholders to recover their investment sooner without any deductions for the Excise Tax and deploy such returned funds as they see fit; (ii) subject to the approval of the Company’s then remaining stockholders after completion of the Mandatory Redemption and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law, as promptly as reasonably possible after completion of the Mandatory Redemption; and (iii) Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

After careful consideration of all relevant factors, including, but not limited to, the IRA and the Excise Tax, the time value of money and the conclusion that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, the Board has determined that the Charter Amendment Proposal is in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” the Charter Amendment Proposal.

If the Charter Amendment Proposal Is Not Approved

TABLE OF CONTENTS

Board may not be able to adjourn the Special Meeting to a later date or dates in the event that there are insufficient votes from the holders of shares of Common Stock at the time of the Special Meeting to approve the Charter Amendment Proposal.

Further, if the Charter Amendment Proposal is not approved, no redemption will be completed until the Original Termination Date, which redemption may be subject to the Excise Tax that could reduce the per-share amount that our Public Stockholder would otherwise be entitled to receive.

In addition, each of the Charter Amendment Proposal and the Trust Amendment Proposal is cross- conditioned on the approval of each other.

If the Charter Amendment Proposal Is Approved

If the Charter Amendment Proposal is approved and implemented, and because the Company will not be able to complete an initial Business Combination by the Amended Termination Date, the Company will (i) immediately after the Special Meeting, cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, complete the Mandatory Redemption; and (iii) as promptly as reasonably possible following such redemption, and subject to the approval of the Company’s then remaining stockholders and the Board, in accordance with applicable law, dissolve and liquidate, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law. The Company also plans to voluntarily delist the Class A Common Stock, Public Warrants and Units from NASDAQ as soon as practicable after completion of the Mandatory Redemption, subject to the rules of NASDAQ and the Second Amended and Restated Charter.

Interests of the Sponsor and the Company’s Officers and Directors

When you consider the recommendation of the Board, stockholders should be aware that aside from their interests as stockholders, the Sponsor and the Company’s officers and directors have interests that differ from the interests of other stockholders generally. The Board was aware of and considered these interests, among other matters, in recommending to the Company’s stockholders that they approve the Charter Amendment Proposal. The Company’s stockholders should take the following interests into account when deciding whether to approve the Charter Amendment Proposal:

•

the fact that the Sponsor and the Company’s officers and directors have agreed not to redeem any shares of Common Stock held by them in connection with a stockholder vote to approve a Business Combination or the Charter Amendment Proposal. Therefore, the 7,175,000 Private Placement Warrants held by the Sponsor, for which the Sponsor paid $7,175,000, and the 6,468,750 ‬shares of Class B Common Stock held by the Initial Stockholders, for which they paid $25,000 will become worthless if the Company is not able to consummate a Business Combination within the required time period;

•	the fact that the Sponsor and the Company’s officers and directors have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any shares of Common Stock (other than Public Shares) held by them;

•

the fact that the Sponsor and the Company’s officers and directors will only be reimbursed for any loans extended, fees due or out-of-pocket expenses either (i) prior to the consummation of an initial Business Combination through funds held outside of the Trust Account or (ii) in connection with or after the consummation of an initial Business Combination. As of June 30, 2022, the Company had

TABLE OF CONTENTS

cash of $77,605 remaining outside of the Trust Account. As of the date of this proxy statement, the Sponsor and the Company’s officers and directors and their affiliates had incurred approximately $[•] of unpaid reimbursable fees and expenses. Such amount will continue to increase if the Charter Amendment Proposal is not approved and implemented; and

•

the fact that, if the Trust Account is liquidated in the event we are unable to complete an initial Business Combination within the required time period, the Sponsor has agreed to indemnify the Company to ensure that the proceeds in the Trust Account are not reduced below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay its taxes, by the claims of prospective target businesses with which the Company has entered into an acquisition agreement or claims of any third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a prospective target business, but only if such a vendor or target business has not executed a waiver of any and all rights to seek access to the Trust Account.

Redemption Rights

Vote Required for Approval

The approval of the Charter Amendment Proposal requires the affirmative vote of the holders of at least 65% of all then outstanding shares of Class A Common Stock and Class B Common Stock. Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Special Meeting and therefore will have no effect on the approval of the Charter Amendment Proposal. The Charter Amendment Proposal is conditioned on the approval of the Trust Amendment Proposal.

In addition to the shares of the Initial Stockholders, the approval of the Charter Amendment Proposal will require the affirmative vote of at least 14,613,388 shares of Common Stock held by the Public Stockholders (or approximately 56.3% of the Class A Common Stock).

Recommendation of the Board

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE CHARTER AMENDMENT PROPOSAL.

TABLE OF CONTENTS

PROPOSAL NO. 2 — THE TRUST AMENDMENT PROPOSAL

Overview

On January 29, 2021, we consummated our initial public offering of 25,875,000‬ Units to our Public Stockholders (each unit comprising one share of Class A Common Stock and one-half of one-redeemable warrant (“Public Warrant”), collectively with the share of Class A Common Stock, a “Unit”), including the issuance of 3,375,000 Units as a result of the underwriters’ exercise of their over-allotment option and the sale of an aggregate of 7,175,000 Private Placement Warrants to our Sponsor. As a result, an amount equal to $258,750,000 was placed in the Trust Account, with Continental acting as trustee. The balance of the Trust Account as of September 30, 2022 was $260,322,011.

Continental’s role as trustee of the Trust Account is subject to the terms and conditions of the Trust Agreement. The Trust Agreement currently provides that Continental shall commence liquidation of the Trust Account only after and promptly after (x) its receipt of the applicable instruction letter delivered by the Company in connection with either a closing of an initial Business Combination or the Company’s inability to effect an initial Business Combination within the time frame specified in the Charter or (y) the Original Termination Date. The Trust Agreement further provides that the provision described in the preceding sentence may not be modified, amended or deleted without the affirmative vote of 65% of the then outstanding shares of Class A Common Stock and Class B Common Stock of the Company, voting together as a single class.

Reasons for the Trust Amendment Proposal

We propose to amend the Trust Agreement, pursuant to an amendment to the Trust Agreement in the form set forth in Annex B of this proxy statement, to change the date on which Continental must commence liquidation of the Trust Account to the Amended Termination Date, such that Continental shall commence liquidation of the Trust Account promptly upon the Amended Termination Date once the Trust Amendment Proposal is approved at the Special Meeting.

After careful consideration of all relevant factors, including, but not limited to, the IRA and the Excise Tax, the time value of money and the conclusion that it is very unlikely that the Company would be able to complete a Business Combination before the Original Termination Date, the Board has determined that the Trust Amendment Proposal is in the best interests of the Company and its stockholders and recommends that you vote or give instruction to vote “FOR” the Trust Amendment Proposal.

Consequences if the Trust Amendment Proposal Is Not Approved

If, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of shares of Common Stock to approve the Trust Amendment Proposal, the Company may put the Adjournment Proposal to a vote in order to seek additional time to obtain sufficient votes in support of the Trust Amendment Proposal. If the Adjournment Proposal is not approved by the Company’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date or dates in the event that there are insufficient votes from the holders of shares of Common Stock at the time of the Special Meeting to approve the Trust Amendment Proposal.

If the Trust Amendment Proposal is not approved at the Special Meeting or at any adjournment thereof or is not implemented, and a Business Combination is not completed on or before the Original Termination Date, then as contemplated by and in accordance with the Trust Agreement, Continental shall commence liquidation of the Trust Account only and promptly (x) after its receipt of the applicable instruction letter delivered by the Company in connection with the Company’s inability to effect an initial Business Combination within the time frame specified in the Charter or (y) upon the Original Termination Date, if the aforementioned termination letter has not been received by Continental prior to such date.

In addition, each of the Trust Amendment Proposal and the Charter Amendment Proposal is cross- conditioned on the approval of each other. Due to this cross-conditionality, if the Trust Amendment Proposal is not approved, no redemption will be completed until the Original Termination Date, which redemption may be subject to the Excise Tax that could reduce the per-share amount that our Public Stockholders would otherwise be entitled to receive.

Therefore, the 7,175,000 Private Placement Warrants held by the Sponsor, for which the Sponsor paid $7,175,000, and the 6,468,750 shares of Class B Common Stock held by the Initial Stockholders, for which they paid $25,000 will become worthless if the Company is not able to consummate a Business Combination within the required time period; and

Recommendation of the Board

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE TRUST AMENDMENT PROPOSAL.

TABLE OF CONTENTS

PROPOSAL NO. 3 — THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal asks stockholders to approve the adjournment of the Special Meeting to a later date or dates or sine die, if necessary, either (x) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal or (y) if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the Charter Amendment Proposal and/or the Trust Amendment Proposal. In either such event, the Company will ask stockholders to vote only upon the Adjournment Proposal and not on the Charter Amendment Proposal and/or the Trust Amendment Proposal.

Consequences if the Adjournment Proposal Is Not Approved

If the Adjournment Proposal is not approved by the Company’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date in the event, based on the tabulated votes, there are insufficient votes from the holders of shares of Common Stock to approve the Charter Amendment Proposal and/or the Trust Amendment Proposal. In such event, the Charter Amendment Proposal and/or the Trust Amendment Proposal would not be implemented.

Vote Required for Approval

The approval of the Adjournment Proposal requires the affirmative vote of the holders of at least a majority of all then outstanding shares of Class A Common Stock and Class B Common Stock, voting as a single class, who are present in person or represented by proxy and entitled to vote thereon at the Special Meeting. Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Special Meeting and therefore and will have the effect of a vote “AGAINST” the Adjournment Proposal.

In addition to the shares of the Initial Stockholders, the approval of the Adjournment Proposal will require the affirmative vote of at least 9,744,126 shares of Common Stock held by the Public Stockholders (or approximately 37.5% of the Class A Common Stock) if all shares of Common Stock are represented at the Special Meeting and cast votes, and the affirmative vote of at least 1,628,689 shares of Common Stock held by the Public Stockholders (or approximately 6% of the Class A Common Stock) if only such shares as are required to establish a quorum are represented at the Special Meeting and cast votes.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR STOCKHOLDERS FOR THE REDEMPTION OF PUBLIC SHARES

The following is a discussion of U.S. federal income tax considerations generally applicable to the redemption of Public Shares for cash in connection with our liquidation in the event the Charter Amendment Proposal and the Trust Amendment Proposal are approved, and the expiration of warrants in such event. This discussion applies only to Public Shares and warrants that are held as capital assets for U.S. federal income tax purposes (generally, property held for investment). This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to holders in light of their particular circumstances or status, including:

•	the Sponsor or our directors and officers;

•	financial institutions or financial services entities;

•	broker-dealers;

•	taxpayers that that are subject to the mark-to-market method of accounting;

•	tax-exempt entities;

•	governments or agencies or instrumentalities thereof;

•	insurance companies;

•	regulated investment companies or real estate investment trusts;

•	expatriates or former long-term residents of the United States;

•	persons that actually or constructively own five percent or more of our voting shares or five percent or more of the total value of all classes of our shares;

•	persons that acquired Series A Common Stock pursuant to an exercise of employee stock options or upon payout of a restricted stock unit, in connection with employee stock incentive plans or otherwise as compensation or in connection with the performance of services;

•	persons that hold Series A Common Stock as part of a straddle, constructive sale, hedging, conversion or other integrated or similar transaction;

•	persons whose functional currency is not the U.S. dollar;

•	controlled foreign corporations; and

•	passive foreign investment companies.

This discussion is based on the Internal Revenue Code of 1986 (the “Code”), proposed, temporary and final Treasury Regulations promulgated under the Code, and judicial and administrative interpretations thereof, all as of the date hereof. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax considerations described herein. This discussion does not address U.S. federal taxes other than those pertaining to U.S. federal income taxation (such as estate or gift taxes, the alternative minimum tax or the Medicare tax on investment income), nor does it address any aspects of U.S. state or local or non-U.S. taxation. We have not and do not intend to seek any rulings from the Internal Revenue Service (the “IRS”) regarding the tax consequences described herein. There can be no assurance that the IRS will not take positions inconsistent with the considerations discussed below or that any such positions would not be sustained by a court.

This discussion does not consider the tax treatment of partnerships or other pass-through entities or persons who hold our securities through such entities. If a partnership (or any entity or arrangement so characterized for U.S. federal income tax purposes) holds Public Shares or warrants, the tax treatment of such partnership and a person treated as a partner of such partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships holding our securities and persons that are treated as partners of such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences to them of the transactions described herein.

TABLE OF CONTENTS

EACH HOLDER SHOULD CONSULT ITS TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF A REDEMPTION OF PUBLIC SHARES AND EXPIRATION OF WARRANTS, INCLUDING THE EFFECTS OF U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX LAWS.

U.S. Holders

As used herein, a “U.S. Holder” is a beneficial owner of Series A Common Stock or warrants who or that is, for U.S. federal income tax purposes:

•	an individual citizen or resident of the United States,

•	a corporation (or other entity that is treated as a corporation for U.S. federal income tax purposes) that is created or organized (or treated as created or organized) in or under the laws of the United States or any state thereof or the District of Columbia,

•	an estate whose income is subject to U.S. federal income tax regardless of its source, or

•	a trust if (1) a U.S. court can exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in place to be treated as a U.S. person.

If a beneficial owner of our securities is not described as a U.S. Holder and is not an entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes, such owner will be considered a “non-U.S. Holder.” The U.S. federal income tax considerations specifically applicable to non-U.S. Holders are described below under the heading “Non-U.S. Holders.”

Redemption of Public Shares

Imposition of Excise Tax

The IRA imposes a 1% excise tax on the fair market value of stock repurchased by a domestic corporation beginning in 2023, with certain exceptions. For this purpose, a “repurchase” includes any “redemption” within the meaning of Section 317(b) of the Code and any transaction that the Treasury Department determines is economically similar to a redemption. This definition would generally include corporate buybacks and other transactions in which a corporation acquires (or is deemed to acquire) its stock from a shareholder in exchange for cash or other property. Because we are a Delaware corporation and our securities trade on the NASDAQ, we will be a “covered corporation” within the meaning of the IRA, and while not free from doubt, it is possible that the Excise Tax will apply to any redemptions of our common stock after December 31, 2022 in the event the Charter Amendment Proposal and Trust Amendment Proposal are not approved or implemented, unless an exemption is available. Consequently, the value of your investment in our securities may decrease as a result of the Excise Tax if the Charter Amendment Proposal and Trust Amendment Proposal are not approved. The application of the Excise Tax in the event of a liquidation is uncertain, and the proceeds held in the trust account could be subject to the Excise Tax, in which case the per-share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.

Redemption of Public Shares in Connection with Our Liquidation

In the event that each of the Charter Amendment Proposal and Trust Amendment Proposal are approved and implemented, a U.S. Holder’s receipt of cash for its Public Shares in connection with our liquidation is expected to be treated as a distribution to such holder in complete liquidation of the Company, with such distribution treated as a payment received in exchange for such Public Shares under Section 331 of the Code. The consequences of such distribution are generally as described below under the section entitled “— U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Public Shares.” In the event the Charter Amendment Proposal and Trust Amendment Proposal are each approved, such redemption is expected to occur no later than December 30, 2022.

While not certain, a redemption of Public Shares in connection with our liquidation may be subject to the Excise Tax in the event that each of the Charter Amendment Proposal and Trust Amendment Proposal are not approved or implemented, as discussed in “— U.S. Holders — Redemption of Public Shares — Imposition of Excise Tax.” U.S. Holders should consult their tax advisors as to the tax consequences of a redemption of Public Shares described in connection with our liquidation, including any special reporting requirements.

TABLE OF CONTENTS

Taxation of Non-Liquidating Distributions

If the redemption of a U.S. Holder’s Public Shares is treated as a non-liquidating distribution, such distribution will generally be treated as a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. A non-liquidating distribution in excess of our current and accumulated earnings and profits generally will constitute a return of capital that will be applied against and reduce (but not ‘below zero) the U.S. Holder’s adjusted tax basis in its Public Shares. Any remaining excess will generally be treated as gain from the sale or exchange of such Public Shares and will be treated as described under “—U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Public Shares” below.

Dividends we pay to a U.S. Holder that is a taxable corporation will generally qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends we pay to a non-corporate U.S. Holder will generally constitute “qualified dividends” that will be subject to tax at the applicable tax rate accorded to long-term capital gains. It is unclear whether the redemption with respect to the Public Shares described in this proxy statement may prevent a U.S. Holder from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate on qualified dividend income, as the case may be.

Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Public Shares

If the redemption of a U.S. Holder’s Public Shares is treated as a sale or exchange, as discussed above, a U.S. Holder will generally recognize capital gain or loss in an amount equal to the difference between (i) the amount realized and (ii) the U.S. Holder’s adjusted tax basis in the Public Shares redeemed.

Under tax law currently in effect, long-term capital gains recognized by non-corporate U.S. Holders are generally subject to U.S. federal income tax at a reduced rate of tax. Capital gain or loss will constitute long-term capital gain or loss if the U.S. Holder’s holding period for the Public Shares exceeds one year. However, it is unclear whether the redemption with respect to the Public Shares described in this proxy statement may prevent the holding period of the Public Shares from commencing prior to the termination of such rights. The deductibility of capital losses is subject to various limitations. U.S. Holders who hold different blocks of Public Shares (Public Shares purchased or acquired on different dates or at different prices) should consult their tax advisor to determine how the above rules apply to them.

Expiration of a Warrant

If the Charter Amendment Proposal and Trust Amendment Proposal are each approved, our warrants, which do not become exercisable unless we complete an initial Business Combination, will expire worthless. In such case, a U.S. Holder will generally recognize a capital loss equal to such holder’s tax basis in the expired warrants. The deductibility of capital losses is subject to various limitations that are not described herein because a discussion of such limitations depends on each U.S. Holder’s particular facts and circumstances.

Non-U.S. Holders

Taxation of Non-Liquidating Distributions

If the redemption of a non-U.S. Holder’s Public Shares is treated as a non-liquidating distribution, as discussed above, such distribution will generally be treated as a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Provided such dividend is not effectively connected with the non-U.S. Holder’s conduct of a trade or business within the United States, we (or another applicable withholding agent) will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, as applicable). Any portion of a non-liquidating distribution not constituting a dividend will be treated first as reducing (but not below zero) the non-U.S. Holder’s adjusted tax basis in its shares of Public Shares and, to the extent such distribution exceeds the non-U.S. Holder’s adjusted tax basis, as gain from the sale or exchange of the Public Shares (taxed as described below under “— Non-U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Public Shares”).

TABLE OF CONTENTS

Non-liquidating distributions to a non-U.S. Holder treated as dividends that are effectively connected with such non-U.S. Holder’s conduct of a trade or business within the United States (or, if an applicable income tax treaty so provides, that are attributable to a U.S. permanent establishment or fixed base maintained by the non-U.S. Holder) will generally not be subject to U.S. withholding tax, provided such non-U.S. Holder complies with certain certification and disclosure requirements (usually by providing an IRS Form W-8ECI). Instead, such dividends will generally will be subject to U.S. federal income tax, net of certain deductions, at the same graduated individual or corporate rates applicable to U.S. Holders. If the non-U.S. Holder is a corporation, dividends that are effectively connected income may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Public Shares

A non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax in respect of gain recognized on a redemption of Public Shares that is treated as a sale or exchange in connection with our liquidation, unless:

•	the gain is effectively connected with the conduct of a trade or business by the non-U.S. Holder within the United States (and, if an applicable tax treaty so requires, is attributable to a U.S. permanent establishment or fixed base maintained by the non-U.S. Holder);

•	the non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met; or

•	we are or have been a “United States real property holding corporation” (“USRPHC”) for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the non-U.S. Holder held the Public Shares.

Gain described in the first bullet point above will generally be subject to tax at generally applicable U.S. federal income tax rates as if the non-U.S. Holder were a U.S. resident. Any gains described in the first bullet point above of a non-U.S. Holder that is a foreign corporation may also be subject to an additional “branch profits tax” at a 30% rate (or lower applicable treaty rate). Gain described in the second bullet point above will generally be subject to a flat 30% U.S. federal income tax. Non-U.S. Holders should consult their tax advisors regarding possible eligibility for benefits under income tax treaties.

Generally, a corporation is a USRPHC if the fair market value of its “United States real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus other assets used or held for use in a trade or business, as determined for U.S. federal income tax purposes. Based on the current composition of our assets, we believe we are not currently a USRPHC.

Expiration of a Warrant

If the Charter Amendment Proposal and Trust Amendment Proposal are approved, our warrants, which do not become exercisable unless we complete an initial Business Combination, will expire worthless. In such case, a non-U.S. Holder will generally recognize a capital loss equal to such holder’s tax basis in the expired warrants. The deductibility of capital losses is subject to various limitations that are not described herein because a discussion of such limitations depends on each non-U.S. Holder’s particular facts and circumstances.

INFORMATION ABOUT THE COMPANY

General

IPO and Private Placement

On January 29, 2021, we consummated our initial public offering of 25,875,000‬ Units, including the issuance of 3,375,000 Units as a result of the underwriters’ exercise of their over-allotment option. The Units were sold at a price of $10.00 per share, generating gross proceeds of $258,750,000. The shares sold in the offering were registered under the Securities Act of 1933, as amended, on a registration statement on Form S-1 (No. 333- 251922). The SEC declared the registration statement effective on January 26, 2021. Concurrently with the closing of the IPO, we consummated the sale of an aggregate of 7,175,000 Private Placement Warrants, at a price of $1.00 per Private Placement Warrant, to our Sponsor for an aggregate purchase price of $7,175,000. The Private Placement Warrants are identical to the Public Warrants, except that, so long as they are held by the Sponsor or its permitted transferees: (i) they will not be redeemable by the Company (except in certain redemption scenarios when the price per share of Common Stock equals or exceeds $10.00 (as adjusted)), (ii) they (including the shares of Common Stock issuable upon exercise of the Private Placement Warrants) may not, subject to certain limited exceptions, be transferred, assigned or sold by the Sponsor until 30 days after the completion of the Company’s initial Business Combination, (iii) they may be exercised by the holders on a cashless basis, and (iv) they (including the shares of Common Stock issuable upon exercise of the Private Placement Warrants) are entitled to registration rights. The Sponsor has entered into an agreement with us pursuant to which they have agreed to waive their redemption rights with respect to any shares of Common Stock issuable upon exercise of the Private Placement Warrants.

The net proceeds from the issuance of these shares were placed in the Trust Account and were placed in a U.S.-based, non-interest-bearing trust account at JP Morgan Chase Bank, N.A.

Transaction costs amounted to approximately $15 million, consisting of $5,175,000 of underwriting commissions, $9,056,250 of deferred underwriting commissions and $436,224 of other offering costs.

BENEFICIAL OWNERSHIP OF

SECURITIES

The following table sets forth information available to us as of October 28, 2022, with respect to our shares of Common Stock held by:

•	each person known by us to be the beneficial owner of more than 5% of our outstanding shares of Common Stock;

•	each of our named executive officers and directors; and

•	all of our executive officers and directors as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if such person possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

In the table below, percentage ownership is based on 32,343,750 shares of Common Stock, consisting of (i) 25,875,000‬ shares of Class A Common Stock and (ii) 6,468,750 shares of Class B Common Stock, issued and outstanding as of October 28, 2022. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we only take into account shares of Common Stock issuable pursuant to the exercise of outstanding warrants if such warrants may be exercised on or before the 60th day after October 28, 2022. None of our outstanding warrants are exercisable on or before such date.

Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all shares of Common Stock beneficially owned by them.

HOUSEHOLDING INFORMATION

Unless the Company has received contrary instructions, it may send a single copy of this proxy statement to any household at which two or more stockholders reside if the Company believes the stockholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce the Company’s expenses. However, if stockholders prefer to receive multiple sets of the Company’s disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. Similarly, if an address is shared with another stockholder and together both of the stockholders would like to receive only a single set of the Company’s disclosure documents, the stockholders should follow these instructions:

•	If the shares are registered in the name of the stockholder, the stockholder should contact us at our offices at Fortistar Sustainable Solutions Corp., One North Lexington Avenue, White Plains, NY 10601, to inform us of his or her request; or

•	If a bank, broker or other nominee holds the shares, the stockholder should contact the bank, broker or other nominee directly.

Notwithstanding the foregoing, except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), holders of shares of any series of Common Stock shall not be entitled to vote on any amendment to this Amended and Restated Certificate (including any amendment to any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock or other series of Common Stock if the holders of such affected series of Preferred Stock or Common Stock, as applicable, are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate (including any Preferred Stock Designation) or the DGCL.

•

the numerator shall be equal to the sum of (A) 25% of all shares of Class A Common Stock issued or issuable (upon the conversion or exercise of any Equity-linked Securities or otherwise) in each case by the Corporation related to or in connection with the consummation of the initial Business Combination (excluding any shares of Class A Common Stock or Equity-linked Securities issued or issuable to any seller in the initial Business Combination) plus (B) the number of shares of Class B Common Stock issued and outstanding prior to the closing of the initial Business Combination; and

•	the denominator shall be the number of shares of Class B Common Stock issued and outstanding prior to the closing of the initial Business Combination.

A-2

TABLE OF CONTENTS

As used herein, the term “Equity-linked Securities” means any securities of the Corporation which are convertible into, exchangeable for or exercisable for Common Stock.

Notwithstanding anything to the contrary contained herein, (i) the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional shares of Class A Common Stock or Equity-linked Securities by the written consent or agreement of holders of a majority of the shares of Class B Common Stock then outstanding consenting or agreeing separately as a single class in the manner provided in Section 4.3(b)(iii), and (ii) in no event shall the Class B Common Stock convert into Class A Common Stock at a ratio that is less than one-for-one.

The foregoing conversion ratio shall also be adjusted to account for any subdivision (by stock split, subdivision, exchange, stock dividend, reclassification, recapitalization or otherwise) or combination (by reverse stock split, exchange, reclassification, recapitalization or otherwise) or similar reclassification or recapitalization of the outstanding shares of Class A Common Stock into a greater or lesser number of shares occurring after the original filing of this Amended and Restated Certificate without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalization of the outstanding shares of Class B Common Stock.

Each share of Class B Common Stock shall convert into its pro rata number of shares of Class A Common Stock pursuant to this Section 4.3(b). The pro rata share for each holder of Class B Common Stock will be determined as follows: Each share of Class B Common Stock shall convert into such number of shares of Class A Common Stock as is equal to the product of one (1) multiplied by a fraction, the numerator of which shall be the total number of shares of Class A Common Stock into which all of the issued and outstanding shares of Class B Common Stock shall be converted pursuant to this Section 4.3(b) and the denominator of which shall be the total number of issued and outstanding shares of Class B Common Stock at the time of conversion.

(iii) Voting. Except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), for so long as any shares of Class B Common Stock shall remain outstanding, the Corporation shall not, without the prior vote or written consent of the holders of a majority of the shares of Class B Common Stock then outstanding, voting separately as a single class, amend, alter or repeal any provision of this Amended and Restated Certificate, whether by merger, consolidation or otherwise, if such amendment, alteration or repeal would alter or change the powers, preferences or relative, participating, optional or other or special rights of the Class B Common Stock. Any action required or permitted to be taken at any meeting of the holders of Class B Common Stock may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the outstanding Class B Common Stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of Class B Common Stock were present and voted and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which minutes of proceedings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. Prompt written notice of the taking of corporate action without a meeting by less than unanimous written consent of the holders of Class B Common Stock shall, to the extent required by law, be given to those holders of Class B Common Stock who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consents signed by a sufficient number of holders of Class B Common Stock to take the action were delivered to the Corporation.

(c) Dividends. Subject to applicable law, the rights, if any, of the holders of any outstanding series of the Preferred Stock and the provisions of Article IX hereof, the holders of shares of Common Stock shall be entitled to receive such dividends and other distributions (payable in cash, property or capital stock of the Corporation) when, as and if declared thereon by the Board from time to time out of any assets or funds of the Corporation legally available therefor and shall share equally on a per share basis in such dividends and distributions.

(d) Liquidation, Dissolution or Winding Up of the Corporation. Subject to applicable law, the rights, if any, of the holders of any outstanding series of the Preferred Stock and the provisions of Article IX hereof, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the

Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of shares of Common Stock shall be entitled to receive all the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Class A Common Stock (on an as converted basis with respect to the Class B Common Stock) held by them.

Section 4.4 Rights and Options. The Corporation has the authority to create and issue rights, warrants and options entitling the holders thereof to acquire from the Corporation any shares of its capital stock of any class or classes, with such rights, warrants and options to be evidenced by or in instrument(s) approved by the Board. The Board is empowered to set the exercise price, duration, times for exercise and other terms and conditions of such rights, warrants or options; provided, however, that the consideration to be received for any shares of capital stock issuable upon exercise thereof may not be less than the par value thereof.

Section 8.1 Limitation of Director Liability. A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended unless they violated their duty of loyalty to the Corporation or its stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived improper personal benefit from their actions as directors.

A-5

TABLE OF CONTENTS

Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such indemnitee in connection with such proceeding. The Corporation shall to the fullest extent not prohibited by applicable law pay the expenses (including attorneys’ fees) incurred by an indemnitee in defending or otherwise participating in any proceeding in advance of its final disposition; provided, however, that, to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it shall ultimately be determined that the indemnitee is not entitled to be indemnified under this Section 8.2 or otherwise. The rights to indemnification and advancement of expenses conferred by this Section 8.2 shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators. Notwithstanding the foregoing provisions of this Section 8.2(a), except for proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board.

(d) This Section 8.2 shall not limit the right of the Corporation, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than indemnitees.

Notwithstanding anything to the contrary contained in this Amended and Restated Certificate, there shall be no Redemption Rights or liquidating distributions with respect to any warrant issued pursuant to the Offering.

(c) The exercise by a Public Stockholder of the Redemption Rights shall be conditioned on such Public Stockholder following the specific procedures for redemptions set forth by the Corporation in any applicable tender offer or proxy materials sent to Public Stockholders relating to the proposed initial Business Combination.

In addition to the foregoing, the doctrine of corporate opportunity shall not apply to any other corporate opportunity with respect to any of the directors or officers of the Corporation unless such corporate opportunity is offered to such person solely in his or her capacity as a director or officer of the Corporation and such opportunity is one the Corporation is legally and contractually permitted to undertake and would otherwise be reasonable for the Corporation to pursue.

ARTICLE XI

AMENDMENT OF AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

TABLE OF CONTENTS

and, except as set forth in Article VIII, all rights, preferences and privileges of whatever nature herein conferred upon stockholders, directors or any other persons by and pursuant to this Amended and Restated Certificate in its present form or as hereafter amended are granted subject to the right reserved in this Article XI; provided, however, that Article IX of this Amended and Restated Certificate may be amended only as provided therein.

ARTICLE XII

EXCLUSIVE FORUM FOR CERTAIN LAWSUITS

Section 12.1 Forum. Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation, its directors, officers or employees arising pursuant to any provision of the DGCL or this Amended and Restated Certificate or the Bylaws, or (iv) any action asserting a claim against the Corporation, its directors, officers or employees governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. This exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act, the Securities Act of 1933, as amended (the “Securities Act”), or any other claim for which the federal courts have exclusive jurisdiction. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder and Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act, the Securities Act, or any other claim for which the federal courts have exclusive jurisdiction.

Section 12.2 Consent to Jurisdiction.
