NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

OF ARENA FORTIFY ACQUISITION CORP.

TO BE HELD ON DECEMBER 8, 2022

To the Stockholders of Arena Fortify Acquisition Corp.:

NOTICE IS HEREBY GIVEN that a special meeting of the stockholders of Arena Fortify Acquisition Corp., a Delaware corporation (“Arena,” the “Company”, “we” or “us”), will be held on December 8, 2022, at 8:00 a.m., Eastern Time, as a completely virtual meeting, conducted over the internet via live audio webcast with no physical in-person meeting, at https://www.cstproxy.com/arenafortify/2022, or at such other time, on such other date and at such other place to which the Special Meeting may be postponed or adjourned (the “Special Meeting”). You can attend the Special Meeting, vote, and submit questions via live audio webcast by visiting https://www.cstproxy.com/arenafortify/2022 and entering the control number found on your proxy card.

You are cordially invited to attend the Special Meeting that will be held for the purpose of considering and voting on the following proposals:

1. Proposal No. 1 — Charter Amendment Proposal — To permit the Company to liquidate and wind up early (“Early Liquidation”) by amending the Company’s Amended and Restated Certificate of Incorporation (“Charter”) to (i) change the date by which the Company must consummate a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, which we refer to as our initial business combination, from February 15, 2023 (the “Original Termination Date”) to December 9, 2022 (the “Amended Termination Date”), (ii) remove the Redemption Limitation (as defined in the Charter) to allow the Company to redeem Public Shares (as defined below) notwithstanding the fact that such redemption would result in the Company having net tangible assets of less than $5,000,001, and (iii) allow the Company to remove up to $100,000 of interest earned on the amount on deposit in the Trust Account (as defined below) prior to redeeming the Public Shares in connection with the Special Meeting in order to pay dissolution expenses (the “Charter Amendment Proposal”); and

2. Proposal No. 2 — Adjournment Proposal — To adjourn the Special Meeting to a later date or dates, if necessary, 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 the Company’s 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 or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate (the “Adjournment Proposal”).

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE CHARTER AMENDMENT PROPOSAL AND, IF PRESENTED, THE ADJOURNMENT PROPOSAL.

The purpose of the Charter Amendment Proposal is to allow Arena to return the proceeds of its initial public offering and related transactions, which were deposited in a trust account (“Trust Account”) established for the benefit of the holders (“Public Stockholders”) of shares of Class A Common Stock initially included in the units sold as part of the initial public offering (the “Public Shares”), to its Public Stockholders earlier than currently contemplated under the Charter and enable Public Stockholders to recover their investment without having to wait for approximately another two months to do so. The approval of the Charter Amendment Proposal is a condition to implementing the Early Liquidation. If the Charter Amendment Proposal is approved, the Company will file an amendment to the Charter substantially in the form of Annex A and will effect the Early Liquidation as soon as practicable after the Special Meeting.

The purpose of the Adjournment Proposal is to allow the Company to adjourn the Special Meeting to a later date or dates to permit further solicitation and vote of proxies or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate. The Adjournment Proposal is not conditioned upon the approval of the Charter Amendment Proposal. If the Charter Amendment Proposal is 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 time value of money, existing market conditions, the possible imposition of the 1% excise tax on stock repurchases under the Inflation Reduction Act of 2022 (“IR Act”) (the “1% Excise Tax”) on redemptions by Arena of Class A Common Stock in 2023, and the conclusion that it is unlikely that Arena would be able to complete an initial business combination before the Original Termination Date, the board of directors of the Company (the “Board”) has determined that the Charter Amendment Proposal and the Adjournment Proposal are in the best interests of Arena and its stockholders and recommends that you vote or give instruction to vote “FOR” both of the proposals.

The Board has fixed the close of business on November 4, 2022 (the “Record Date”) as the record date for determining when Arena’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. A complete list of stockholders of record entitled to vote at the Special Meeting will be available for ten days before the Special Meeting online at https://www.cstproxy.com/arenafortify/2022 for inspection by stockholders for any purpose germane to the Special Meeting.

Pursuant to the Charter, if the Charter Amendment Proposal is approved and implemented, a Public Stockholder may request that the Company redeem all or a portion of its Public Shares by following the procedures described in the accompanying proxy statement, for cash at a per-share redemption price equal to the aggregate amount on deposit in the Trust Account as of the Record Date, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the total number of then outstanding Public Shares. Public Stockholders may elect to redeem all or a portion of their Public Shares even if they vote “FOR” the Charter Amendment Proposal and even if they do not hold Public Shares on the Record Date. If the Charter Amendment Proposal is approved by the requisite vote of stockholders, the remaining holders of Public Shares will have their Public Shares redeemed in conjunction with the Early Liquidation.

On the Record Date, the redemption price per share was approximately $10.27 (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 $177.3 million as of the Record Date, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), 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 $10.20. Accordingly, if the market price of the Class A Common Stock were to remain the same until the date of the Special Meeting, exercising redemption rights would result in a Public Stockholder receiving approximately $0.07 more per share than if the shares were sold in the open market. Arena cannot assure stockholders that they will be able to sell their Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its shares when such stockholders wish to sell their shares.

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 17,250,000 issued and outstanding shares of Class A Common Stock and 4,312,500 issued and outstanding shares of Class B Common Stock.

The approval of the Charter Amendment Proposal requires the affirmative vote of at least 50% of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class. As of the date of this proxy statement, the Class B Common Stock, which is held by the initial stockholders (the “Initial Stockholders”) of the Company that held our founders shares prior to our initial public offering (the “IPO”),

including Arena Fortify Sponsor, LLC, the Company’s sponsor (the “Initial Stockholder Shares”), represents 20.0% of the Company’s outstanding Common Stock. Accordingly, in addition to the Initial Stockholder Shares, the Company will need 6,468,750 Public Shares (or approximately 37.5% of the outstanding Class A Common Stock) to be voted in favor of the Charter Amendment Proposal to approve such proposal. Approval of the Charter Amendment Proposal is a condition to the implementation of the Early Liquidation.

The approval of the Adjournment Proposal requires the affirmative vote of at least a majority of the shares of Class A Common Stock and Class B Common Stock, voting as a single class, present in person or represented by proxy and entitled to vote thereon at the Special Meeting. In addition to the Initial Stockholder Shares, approval of the Adjournment Proposal will require the affirmative vote of at least 6,468,751 Public Shares (or approximately 37.5% of the outstanding Class A Common Stock) if all shares of Common Stock are represented at the Special Meeting, and the affirmative vote of at least 1,078,126 Public Shares (or approximately 6.3% of the Class A Common Stock) if only such shares as are required to establish a minimum quorum are represented at the Special Meeting. The Adjournment Proposal will only be put forth for a vote if either there are not sufficient votes to approve the Charter Amendment Proposal at the Special Meeting or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

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

If you have any questions or need assistance voting your Common Stock, please contact Arena by calling (212) 612-3205.

PROXY STATEMENT FOR THE SPECIAL MEETING OF STOCKHOLDERS TO BE HELD ON DECEMBER 8, 2022

You are cordially invited to attend a special meeting of Arena Fortify Acquisition Corp., a Delaware corporation (“Arena,” or the “Company”), which will be held on December 8, 2022, at 8:00 a.m., Eastern Time, virtually over the internet via live audio webcast with no physical in-person meeting, at https://www.cstproxy.com/arenafortify/2022, or at such other time, on such other date and at such other place to which the meeting may be postponed or adjourned (the “Special Meeting”). 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/arenafortify/2022 and entering the control number found on your proxy card.

As more fully described in this proxy statement, which is dated November 16, 2022 and is first being mailed to stockholders on or about that date, the Special Meeting will be held for the purpose of considering and voting on the following proposals:

Proposal No. 1— Charter Amendment Proposal — To permit the Company to liquidate and wind up early (“Early Liquidation”) by amending the Company’s Amended and Restated Certificate of Incorporation (“Charter”) to (i) change the date by which the Company must consummate an initial business combination, from February 15, 2023 (the “Original Termination Date”) to December 9, 2022 (the “Amended Termination Date”), (ii) remove the Redemption Limitation (as defined in the Charter) to allow the Company to redeem Public Shares (as defined below) notwithstanding the fact that such redemption would result in the Company having net tangible assets of less than $5,000,001, and (iii) allow the Company to remove up to $100,000 of interest earned on the amount on deposit in the Trust Account (as defined below) prior to redeeming the Public Shares in connection with the Special Meeting in order to pay dissolution expenses (the “Charter Amendment Proposal”); and

Proposal No. 2 —Adjournment Proposal — To adjourn the Special Meeting to a later date or dates, if necessary, 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 the Company’s Common Stock to approve the Charter Amendment Proposal or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

Each of the Charter Amendment Proposal and the Adjournment Proposal are more fully described in the accompanying proxy statement. Please take the time to read carefully each of the proposals in the accompanying proxy statement before you vote.

The Charter currently provides that Arena has until the Original Termination Date to complete its initial business combination and, if Arena 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, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The purpose of the Charter Amendment Proposal is to allow Arena to return the funds held in the Trust Account to its Public Stockholders earlier than currently contemplated under the Charter and enable Public Stockholders to recover their investment without having to wait for approximately another two months to do so. The approval of the Charter Amendment Proposal is a condition to implementing the Early Liquidation. If the Charter Amendment Proposal is approved, the Company will file an amendment to the Charter substantially in the form of Annex A and will effect the Early Liquidation as soon as practicable after the Special Meeting.

The Board believes that the current provisions of the Charter described above were included to protect Arena’s stockholders from having to sustain their investment for an unreasonably long period if Arena were unable to find a suitable initial business combination target in the timeframe contemplated by the Charter. The Board has determined it is unlikely Arena can complete a business combination by the Original Termination Date due to existing market conditions. The Board further believes that if Arena liquidates in 2023, Arena’s stockholders’ investment may be affected by the IR Act as it believes there is a risk that redemptions of Public Shares by Arena in connection such liquidation could be subject to the 1% Excise Tax. Liquidation in 2022 would therefore potentially return more funds to stockholders than a potential liquidation in 2023. Arena is not, however, permitted by the Charter 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 the rights of holders of Class A Common Stock.

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

The Board has fixed the close of business on November 4, 2022 as the Record Date for determining when Arena’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. A complete list of stockholders of record entitled to vote at the Special Meeting will be available for ten days before the Special Meeting online at https://www.cstproxy.com/arenafortify/2022 for inspection by stockholders for any purpose germane to the Special Meeting.

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 and implemented, by following the procedures set forth in this proxy statement. Public Stockholders may elect to redeem all or a portion of their Public Shares even if they vote “FOR” the Charter Amendment Proposal and even if they do not hold Public Shares on the Record Date. If the Charter Amendment Proposal is approved by the requisite vote of stockholders, the remaining holders of Public Shares will have their Public Shares redeemed in conjunction with the Early Liquidation. Stockholders should note that the redemption price calculated in connection with the Charter Amendment Proposal will take into account up to $100,000 of net interest removed from the Trust Account to pay dissolution expenses upon liquidation.

The approval of the Charter Amendment Proposal requires the affirmative vote of at least 50% of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class. As of the date of this proxy statement, the Initial Stockholder Shares represent 20.0% of the Company’s outstanding Common Stock. Accordingly, in addition to the Initial Stockholder Shares, the Company will only need 6,468,750 Public Shares (or approximately 37.5% of the outstanding Class A Common Stock) to be voted in favor of the Charter Amendment Proposal to approve such proposal. Approval of the Charter Amendment Proposal is a condition to the implementation of the Early Liquidation.

After careful consideration of all relevant factors, including, but not limited to, the time value of money, existing market conditions, the possible imposition of the 1% Excise Tax under the IR Act on redemptions by Arena of Public Shares in 2023, and the conclusion that it is unlikely that Arena would be able to complete an initial business combination before the Original Termination Date the Board has determined that the Charter Amendment Proposal and the Adjournment Proposal are in the best interests of Arena and its stockholders and recommends that you vote or give instruction to vote “FOR” both 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 this 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 will not be counted for the purposes of determining whether a quorum is present at the Special Meeting. Additionally, if you fail to vote, that will have the same effect as a vote AGAINST the Charter Amendment Proposal, but will have no effect on the Adjournment Proposal.

This proxy statement contains important information about the Special Meeting and the proposals to be voted on at the Special Meeting. Please read it carefully and vote your shares.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained in this proxy statement are based on Arena’s current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond Arena’s control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Arena does not guarantee that the transactions and events described will happen as described (or that they will happen at all). Forward-looking statements in this proxy statement may include, for example, statements about:

•

Arena’s ability to complete an initial business combination;

•

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

•

the per-share redemption price of the Public Shares; and

•

the timing of the Early Liquidation and Arena’s dissolution and delisting.

While forward-looking statements reflect Arena’s good faith beliefs, they are not guarantees of future performance. Arena 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 Arena’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 Arena’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”), in its Quarterly Reports on Form 10-Q filed with the SEC, and in other documents filed by Arena with the SEC. You should not place undue reliance on any forward-looking statements, which are based only on information currently available to Arena (or to third parties making the forward-looking statements).

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

The questions and answers below highlight only selected information from this proxy statement and only briefly address some commonly asked questions about the Special Meeting and the proposals to be presented at the Special Meeting. The following questions and answers do not include all the information that is important to Arena stockholders. Stockholders are urged to read carefully this entire proxy statement, including the other documents referred to herein, to fully understand the proposal to be presented at the Special Meeting.

Q:	Why am I receiving this proxy statement?

Arena is a blank check company incorporated as a Delaware corporation on January 26, 2021 and 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 November 15, 2021, the full exercise of the underwriters’ over-allotment option, the concurrent sales of private placement warrants to the Initial Stockholders and the receipt of proceeds from the Initial Stockholder Loans (defined below), approximately $175.9 million was placed in the Trust Account.

Like most blank check companies, Arena’s Charter provides for the return of the funds held in trust to the Public Stockholders if there is no qualifying business combination(s) consummated within (in Arena’s case) 15 months after the date of the closing of the IPO (i.e., by the Original Termination Date).

Q:	When and where will the Special Meeting be held?

The Special Meeting will be held on December 8, 2022, at 8:00 a.m., Eastern Time, virtually over the internet via live audio webcast at https://www.cstproxy.com/arenafortify/2022, or at such other time, on such other date and at such other place to which the Special Meeting may be postponed or adjourned.

For more information, please see the sections of this proxy statement titled “Proposal No. 1 — The Charter Amendment Proposal,” and “Proposal No. 2 — The Adjournment Proposal.”

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

Q:	Why is Arena proposing the Charter Amendment Proposal?

The Charter currently provides that Arena has until the Original Termination Date to complete its initial business combination and, if Arena 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, redeem Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account established by Arena in connection with its initial public offering including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Board believes that the current provisions of the Charter described above were included to protect Arena’s stockholders from having to sustain their investment for an unreasonably long period if Arena were unable to find a suitable initial business combination target in the timeframe contemplated by the Charter. The Board has determined it is unlikely Arena can complete a business combination by the Original Termination Date due to existing market conditions. The Board further believes that if Arena liquidates in 2023, Arena’s stockholders’ investment may be affected by the IR Act as it believes there is a risk that redemptions by Public Shares by Arena in connection with such liquidation could be subject to the 1% Excise Tax. Liquidation in 2022 would therefore potentially return more funds to stockholders than a potential liquidation in 2023. Arena is not, however, permitted by the Charter 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 the rights of holders of Class A Common Stock.

The purpose of the Charter Amendment Proposal is to allow Arena to return the funds held in the Trust Account to its Public Stockholders earlier than currently contemplated under the Charter and enable Public Stockholders to recover their investment without having to wait for approximately another two months to do so. The approval of the Charter Amendment Proposal is a condition to implementing the Early Liquidation. If the Charter Amendment Proposal is approved, the Company will file an amendment to the Charter substantially in the form of Annex A and will effect the Early Liquidation as soon as practicable after the Special Meeting.

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

In the event the Charter Amendment Proposal is not approved or implemented and Arena is unable to complete a business combination on or before the Original Termination Date, Arena 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. A majority of the outstanding shares of Common Stock entitled to vote at such meeting, represented in person or by proxy, shall constitute a quorum at a meeting of stockholders. Abstentions will be considered present for the purposes of establishing a quorum. The Initial Stockholder Shares, which represent 20.0% of the issued and outstanding Common

Stock as of the Record Date, will count towards this quorum. As a result, as of the Record Date, in addition to the Initial Stockholder Shares, an additional 6,468,751 shares of Common Stock held by the Public Stockholders would be required to be present at the Special Meeting to achieve a quorum. If a quorum is not present, a majority of the shares present may adjourn the meeting from time to time until a quorum shall be present.

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

The approval of the Charter Amendment Proposal requires the affirmative vote of at least 50% of the outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class. As of the date of this proxy statement, the Initial Stockholder Shares represent 20.0% of the Company’s outstanding Common Stock. Accordingly, in addition to the Initial Stockholder Shares, the Company will only need 6,468,750 Public Shares (or approximately 37.5% of the outstanding Class A Common Stock) to be voted in favor of the Charter Amendment Proposal to approve such proposal. Abstentions will have the same effect as a vote “AGAINST” the Charter Amendment Proposal. The Charter Amendment Proposal is a “non-routine” matter, which means that banks, brokers and other nominees will not have authority to vote on the Charter Amendment Proposal unless instructed by the beneficial owner. Broker non-votes will have the same effect as a vote “AGAINST” the proposal because approval requires an absolute percentage of affirmative votes. Approval of the Charter Amendment Proposal is a condition to the implementation of the Early Liquidation.

The approval of the Adjournment Proposal requires the affirmative vote of at least a majority of the shares of Class A Common Stock and Class B Common Stock, voting as a single class, present in person or represented by proxy and entitled to vote thereon at the Special Meeting. Abstentions will have the same effect as a vote “AGAINST” the Adjournment Proposal. The Adjournment Proposal is a “routine” matter, and accordingly, brokers and other nominees will have authority to vote on the Adjournment Proposal in the absence of instruction. Therefore, we do not expect to receive any broker non-votes on this proposal. The Adjournment Proposal will only be put forth for a vote if based upon the tabulated vote at the time of the Special Meeting there are not sufficient votes to approve the Charter Amendment Proposal at the Special Meeting or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

Q:	How will the Sponsor vote?

On the Record Date, the Initial Stockholders owned and were entitled to vote an aggregate of 4,312,500 shares of Common Stock, representing 20.0% of Arena’s issued and outstanding Common Stock. The Initial Stockholders plan to vote in favor of each of the Charter Amendment Proposal, and, if presented, the Adjournment Proposal.

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

The purpose of the Charter Amendment Proposal is to allow Arena to return the funds held in the Trust Account to its Public Stockholders earlier than currently contemplated under the Charter and enable Public Stockholders to recover their investment without having to wait for approximately another two months to do so. The approval of the Charter Amendment Proposal is a condition to implementing the Early Liquidation. If the Charter Amendment Proposal is approved, the Company will file an amendment to the Charter substantially in the form of Annex A and will effect the Early Liquidation as soon as practicable after the Special Meeting.

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

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

If the Adjournment Proposal is not approved by Arena’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 the Company’s Common Stock to approve the Charter Amendment Proposal or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

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

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

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

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 the Company’s Common Stock to approve the Charter Amendment Proposal, Arena 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 Arena’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 the Company’s 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, Arena will (i) cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial business combination by the Original Termination Date or, if the Amendment Proposal is approved, the Amended Termination Date.

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

If the Charter Amendment Proposal is approved and implemented, the Company will file an amendment to the Charter substantially in the form of Annex A and will effect the Early Liquidation as soon as practicable after the Special Meeting. Public Shares which were validly tendered for redemption in connection with the Special Meeting will be redeemed for a per share price, payable in cash, equal to the aggregate amount on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the total number of then outstanding Public Shares.

Thereafter, because Arena will not be able to complete an initial business combination by the Amended Termination Date, Arena will (i) after the Amended Termination Date, cease all operations, except for the

purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the shares the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes, divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Arena also plans to voluntarily delist the Class A Common Stock from Nasdaq as soon as practicable after completion of the Early Liquidation, subject to the rules of Nasdaq and the Charter.

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

Yes. Whether you vote “FOR” or “AGAINST” the Charter Amendment Proposal, or do not vote at all, you may elect to redeem your Public Shares, provided that the Charter Amendment Proposal is approved and implemented. You will need to submit a redemption request for your Public Shares if you choose to redeem. Please see the question “How do I exercise my redemption rights?” below for further information on how to exercise redemption rights.

Q:	Will how I vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights regardless of whether or not you vote for or against the proposals, or vote at all, and regardless of whether you are a holder of Public Shares on the Record Date (so long as you are a holder at the time of exercise). However, under the Charter, Arena is only obligated to provide you with the opportunity to redeem your Public Shares in connection with the Charter Amendment Proposal upon the approval of such proposal.

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 in person (which would include presence at the virtual Special Meeting), revoke your proxy and vote; or (iii) revoke your proxy by sending a notice of revocation to the Board at Arena’s address at 405 Lexington Avenue, 59^th Floor New York, New York 10174, 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:	Each stockholder shall be entitled to one vote virtually or by proxy for each share of Common Stock entitled to vote held by such stockholder.

Votes will be counted by the inspector of election appointed for the Special Meeting, who will separately count “FOR” and “AGAINST” votes, “ABSTAIN” and broker non-votes. Stockholders who attend the Special Meeting, either in person 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, abstentions will be considered present for the purposes of establishing a quorum and as votes “AGAINST” the Charter Amendment Proposal or the Adjournment Proposal. Broker non-votes will be counted as “AGAINST” the Charter Amendment Proposal but will have no effect on the outcome of the Adjournment 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 with respect to the Charter Amendment Proposal. Accordingly, your bank, broker, or other nominee can vote your shares on the Charter Amendment Proposal only if you provide instructions on how to vote. The Adjournment Proposal is considered “routine” and your bank, broker, or other nominee can vote your shares for the Adjournment Proposal without your instruction.

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 Arena or by voting 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. 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?

A:	Yes. After careful consideration of all relevant factors, the Board has determined that the Charter Amendment Proposal is in the best interest of Arena and its stockholders and recommends that you vote or give instruction to vote “FOR” the Charter Amendment Proposal.

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

A:	No. There are no appraisal rights available to Arena’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 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?

A:	If you are a Public Stockholder and wish to exercise your right to redeem your Class A Common Stock, you must:

(i)

(a) hold Public Shares or (b) hold Public Shares through units and you elect to separate your units into the underlying Public Shares and public warrants prior to exercising your redemption rights with respect to the Public Shares; and

(ii)

prior to 5:00 p.m. Eastern Time, on December 6, 2022 (two business days prior to the scheduled vote at the Special Meeting), (a) submit a written request, including the name, phone number, and address of the beneficial owner of the shares for which redemption is requested, to Continental Stock Transfer & Trust Company, the Company’s Transfer Agent, at Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, New York 10004, Attn: Mark Zimkind (e-mail:mzimkind@continentalstock.com), that the Company redeem your Public Shares for cash and (b) deliver your Public Shares to the Transfer Agent, physically or electronically through The Depository Trust Company (“DTC”).

Holders of units must elect to separate the underlying Public Shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage

firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the Transfer Agent directly and instruct it to do so. Public Stockholders may elect to redeem all or a portion of their Public Shares regardless of whether they vote for or against the Charter Amendment Proposal and regardless of whether they hold Public Shares on the record date.

Holders who intend to exercise their redemption rights in connection with the Charter Amendment Proposal must complete the procedures for electing to redeem their Class A Common Stock in the manner described above prior to 5:00 p.m., Eastern Time, on December 6, 2022 (two business days before the scheduled vote at the Special Meeting) in order for their shares to be redeemed.

If you hold your Public Shares in “street name,” you will have to coordinate with your bank, broker or other nominee to have the shares you beneficially own certificated and delivered electronically.

In connection with the approval of the Charter Amendment Proposal, any Public Stockholder will be entitled to request that their Public Shares be redeemed for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the Special Meeting, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding Public Shares. As of the Record Date, this would have amounted to approximately $10.27 per Public Share. However, the funds in the Trust Account could become subject to the claims of our creditors, if any, which could have priority over the claims of our Public Stockholders. Therefore, the per share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. We anticipate that the funds to be distributed to the Public Stockholders electing to redeem their Class A Common Stock in connection with the Charter Amendment will be distributed promptly after the Special Meeting.

Any request for redemption, once made by a Public Stockholder, may be withdrawn at any time up to the vote at the Special Meeting, and thereafter with our consent. If you deliver your shares for redemption to the Transfer Agent and later decide not to elect redemption, you may request that Arena instruct the Transfer Agent to return the shares (physically or electronically). We will be required to honor such request only if made prior to the vote at the Special Meeting. After this time, a request for redemption may not be withdrawn unless the Board determines (in its sole discretion) to permit the withdrawal of such redemption request (which it may do in whole or in part). Such a request must be made by contacting the Transfer Agent at the phone number or address listed under the question “Who can help answer my questions?” below.

If a Public Stockholder properly makes a request for redemption and the Public Shares are delivered as described above and the Charter Amendment Proposal is approved and implemented, then, Arena will redeem such shares of Class A Common Stock for a pro rata portion of funds in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), calculated as of two business days prior to the Special Meeting.

Q:	What will happen to my Public Shares if I do not elect redemption in connection with the Charter Amendment Proposal?

If the Charter Amendment Proposal is approved and implemented, because Arena will not be able to complete an initial business combination by the Amended Termination Date, Arena will (i) after the Amended Termination Date, cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and

income taxes, divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

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?

Arena will pay the cost of soliciting proxies for the Special Meeting. Arena will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of Class A Common Stock for their expenses in forwarding soliciting materials to beneficial owners of Class A Common Stock and in obtaining voting instructions from those owners. The directors, officers and employees of Arena 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:

Arena Fortify Acquisition Corp.

405 Lexington Avenue, 59th Floor

New York, NY 10174

Telephone: (212) 612-3205

You also may obtain additional information about Arena from documents filed with the SEC by following the instructions in the section titled “Where You Can Find More Information.” If you are a Public Stockholder and you intend to seek redemption of your shares, you will need to deliver your shares of Class A Common Stock (either physically or electronically) to the Transfer Agent at the address below prior to 5:00 p.m., Eastern Time, on December 6, 2022 (two business days prior to the date of the Special Meeting). If you have questions regarding the certification of your position or delivery of your shares, please contact:

Continental Stock Transfer & Trust Company

RISK FACTORS

You should consider carefully all of the risks described in Arena’s Annual Report on Form 10-K filed with the SEC on April 1, 2022, any subsequent Quarterly Report on Form 10-Q filed with the SEC and in any other documents Arena files with the SEC. Furthermore, if any of the following events occur, Arena’s business, financial condition and operating results may be materially adversely affected or Arena could face liquidation. In that event, the trading price of Arena securities could decline, and you could lose all or part of your investment. The risks and uncertainties described in the aforementioned filings and below are not the only ones Arena face. Additional risks and uncertainties that Arena is unaware of or that Arena currently believe are not material, may also become important factors that adversely affect Arena’s business, financial condition and operating results or result in Arena’s liquidation.

If the Charter Amendment Proposal is approved, the Company will be permitted to remove up to $100,000 of interest earned on the Trust Account to pay dissolution expenses. Accordingly, Public Stockholders who elect to redeem their Public Shares in connection with the Charter Amendment Proposal may receive a lower per-share redemption price in connection with the Charter Amendment Proposal.

If the Charter Amendment Proposal is approved, Public Stockholders who elect to redeem their Public Shares in connection with the Charter Amendment Proposal will receive a per-share redemption price that takes into account up to $100,000 of net interest removed from the Trust Account to pay dissolution expenses. Such dissolution expenses would reduce the per share amount payable to Public Stockholders who redeem their Public Shares in connection with the Charter Amendment Proposal.

The Proposals at the Special Meeting

$5,000,001, and (iii) allow the Company to remove up to $100,000 of interest earned on the amount on deposit in the Trust Account prior to redeeming the Public Shares in connection with the Special Meeting in order to pay dissolution expenses; and

Proposal No. 2 — Adjournment Proposal — To adjourn the Special Meeting to a later date or dates, if necessary, 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 the Company’s Common Stock to approve the Charter Amendment Proposal or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

Voting Power; Record Date

As a stockholder of Arena, you have a right to vote on certain matters affecting Arena. 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 Common Stock at the close of business on November 4, 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 21,562,500 issued and outstanding shares of Common Stock, of which 17,250,000 shares of Class A Common Stock are held by the Public Stockholders and 4,312,500 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 (which would include presence at the virtual Special Meeting) of a majority of the outstanding shares of Common Stock of the Company entitled to vote at such meeting, represented in person or by proxy, shall constitute a quorum at a meeting of stockholders. Abstentions will be considered present for the purposes of establishing a quorum. The Initial Stockholder Shares, which represent 20.0% of the issued and outstanding 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 Common Stock held by the Initial Stockholders, an additional 6,468,751 shares of Common Stock held by the Public Stockholders would be required to be present at the Special Meeting to achieve a quorum. If a quorum is not present, a majority of the shares present may adjourn the Special Meeting from time to time until a quorum shall be present.

Abstentions and Broker Non-Votes

Abstentions will be considered present for the purposes of establishing a quorum and, as a matter of Delaware law, will constitute votes cast at the Special Meeting and will as votes cast “AGAINST” the Charter Amendment Proposal or the Adjournment Proposal.

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 stockholders, (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.

We believe that the Charter Amendment proposal to be voted on at the Special Meeting will be considered a non-routine matter. 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 the Charter Amendment to be voted on at the Special Meeting without your instruction. We believe that the Adjournment Proposal is considered a routine matter and your bank, brokerage firm or other nominee can vote the shares you beneficially own on the Charter Amendment to be voted on at the Special Meeting without your instruction.

Vote Required for Approval

The approval of the Charter Amendment Proposal requires the affirmative vote of 50% of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class.

Voting Your Shares

If you were a holder of record of Common Stock as of the close of business on November 4, 2022, the Record Date for the Special Meeting, you may vote with respect to the proposals 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. You may still attend the Special Meeting and vote virtually if you have already voted by proxy.

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 Arena Fortify Acquisition Corp., 405 Lexington Avenue, 59^th Floor, New York, New York 10174, before the Special Meeting that you have revoked your proxy.

Simply attending the Special Meeting will not constitute a revocation of your proxy. 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, 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, absent 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.

Redemption Rights

In connection with the approval of the Charter Amendment Proposal, Arena’s Public Stockholders may demand that Arena redeem their Public Shares for a full pro rata portion of the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes, less up to $100,000 of interest for dissolution expenses (which, for illustrative purposes, was approximately $10.27 per share as of November 4, 2022, the Record Date for the Special Meeting), calculated as of two business days prior to the Special Meeting, regardless of whether they vote for or against, or whether they abstain from voting on, the Charter Amendment Proposal. If a holder properly seeks redemption as described in this section and the Charter Amendment Proposal is approved and implemented, Arena will redeem these shares for cash, and the holder will no longer own these shares following the redemption.

As a Public Stockholder, you will be entitled to receive cash for any Class A Common Stock to be redeemed only if you:

(i)

(a) hold Public Shares or (b) hold public shares through units and you elect to separate your units into the underlying Public Shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii)

prior to 5:00 p.m. Eastern Time, on December 6, 2022 (two business days prior to the scheduled vote at the Special Meeting), (a) submit a written request, including the name, phone number, and address of the beneficial owner of the shares for which redemption is requested, to Continental Stock Transfer & Trust Company, the Company’s transfer agent, at Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, New York 10004, Attn: Mark Zimkind (e-mail:mzimkind@continentalstock.com), that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through DTC.

Holders who intend to exercise their redemption rights in connection with the Charter Amendment Proposal must complete the procedures for electing to redeem their Class A Common Stock in the manner described above prior to 5:00 p.m., Eastern Time, on December 6, 2022 (two business days before the Special Meeting) in order for their shares to be redeemed.

If you hold your shares in “street name,” you will have to coordinate with your bank, broker or other nominee to have your shares certificated or delivered electronically. Public Shares that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through DTC’s DWAC system. The Transfer Agent will typically charge the tendering broker $80 and it would be up to the broker whether or not to pass this cost on to the redeeming stockholder.

Transfer Agent and later decide not to elect redemption, you may request that Arena instruct the Transfer Agent to return the shares (physically or electronically). We will be required to honor such request only if made prior to the vote at the Special Meeting. After this time, a request for redemption may not be withdrawn unless the Board determines (in its sole discretion) to permit the withdrawal of such redemption request (which it may do in whole or in part). Such a request must be made by contacting the Transfer Agent at the phone number or address listed under the question “Who can help answer my questions?” above.

Any corrected or changed written exercise of redemption rights in connection with the redemption must be received by the Transfer Agent prior to the deadline for exercising redemption requests in connection with the redemption and, thereafter, prior to the redemption withdrawal deadline. No request for such redemption will be honored unless the holder’s shares have been delivered (either physically or electronically) to the Transfer Agent, prior to 5:00 p.m., Eastern Time, on December 6, 2022 (two business days before the Special Meeting).

If a Public Stockholder properly makes a request for redemption and the shares of Class A Common Stock are delivered as described above and the Charter Amendment Proposal is approved and implemented, then, Arena will redeem such shares of Class A Common Stock for a pro rata portion of funds in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), calculated as of two business days prior to the Special Meeting. Prior to exercising redemption rights, stockholders should verify the market price of Class A Common Stock as they may receive higher proceeds from the sale of their Class A Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. Arena cannot assure its stockholders that they will be able to sell their Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its shares when its stockholders wish to sell their shares.

If a Public Stockholder exercises his, her or its redemption rights in connection with the Charter Amendment Proposal, then he, she or it will be exchanging his, her or its Class A Common Stock for cash and will no longer own those shares. You will be entitled to receive cash for these shares only if you properly demand redemption by delivering your stock certificate (either physically or electronically) to the Transfer Agent as described above and the Charter Amendment Proposal is approved and implemented.

In addition, if the Charter Amendment Proposal is approved and implemented, because Arena will not be able to complete an initial business combination by the Amended Termination Date, Arena will (i) after the Amended Termination Date, cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes, divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

For a discussion of certain U.S. federal income tax considerations for stockholders with respect to the exercise of these redemption rights, see “Certain U.S. Federal Income Tax Considerations.” 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 exercise of your redemption rights, including the applicability and effect of U.S. federal, state and local and non-U.S. income and other tax laws in light of your particular circumstances.

Appraisal Rights

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

Directors, officers and employees of Arena who solicit proxies will not be paid any additional compensation for soliciting.

PROPOSAL NO. 1 — THE CHARTER AMENDMENT PROPOSAL

Overview

Arena is proposing to amend the Charter to (i) change the date by which the Company must consummate an initial business combination, from February 15, 2023 to December 9, 2022 in order to permit the Company to liquidate and wind up early, (ii) remove the Redemption Limitation (as defined in the Charter) to allow the Company to redeem Public Shares notwithstanding the fact that such redemption would result in the Company having net tangible assets of less than $5,000,001, and (iii) allow the Company to remove up to $100,000 of interest earned on the amount on deposit in the Trust Account prior to redeeming the Public Shares in connection with the Special Meeting in order to pay dissolution expenses.

On the Record Date, the redemption price per share was approximately $10.27 (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 $177.3 million as of the Record Date, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes, (less up to $100,000 of interest to pay dissolution expenses), 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 $10.20. Accordingly, if the market price of the Class A Common Stock were to remain the same until the date of the Special Meeting, exercising redemption rights would result in a Public Stockholder receiving approximately $0.07 more per share than if the shares were sold in the open market. Arena cannot assure stockholders that they will be able to sell their Class A Common Stock in the open market, even if the market price per share is higher 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

Arena 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. After the closing of the IPO in November 2021, and consistent with Arena’s business purpose, the Board and Arena’s management commenced an active search for potential business combination targets, leveraging Arena’s and the Sponsor’s network of relationships and intimate knowledge of the private company marketplace.

As of the date of this proxy statement, Arena has not entered into an agreement to effectuate a business combination with any of the targets that it has reviewed due to a variety of reasons, including, among other things: (i) volatile market conditions; (ii) inability to reach an agreement on an appropriate valuation; (iii) a declining new issuance market in 2022; (iv) Arena’s assessments of the targets business model, customers, the competitive landscape in the relevant industry and risks to future financial performance; (v) Arena’s preliminary assessment of relevant target companies’ ability to scale their respective businesses; 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 over the past 12 months, Arena’s management has encountered material changes in the market valuations of public company transactions and SPAC valuations since the IPO. This has created divergent expectations of valuation between SPACs like Arena 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 term such that Arena will not be able to identify, agree upon and consummate a business combination with a suitable target that meets Arena’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 Arena’s prospects for consummating a business combination, including 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 Arena’s ability to complete an initial business combination in the two months remaining before the Original Termination Date.

Moreover, the IR Act, among other things, imposes the 1% Excise Tax on the fair market value of certain repurchases (including certain redemptions) of stock by publicly traded domestic (i.e., U.S.) corporations occurring after December 31, 2022. The amount of the excise tax is generally 1% of the fair market value of the shares of stock repurchased at the time of the repurchase (with certain exceptions), reduced by the fair market value of certain new issuances of shares of stock by such corporation within the same taxable year. The IR Act did not provide an exception for repurchases or redemptions of shares of stock of a corporation in complete or partial liquidation of such corporation. The U.S. Department of Treasury has been given authority to provide regulations and other guidance to carry out, and prevent the abuse or avoidance of, the 1% Excise Tax; however, no guidance has been issued to date. Absent such guidance, because Arena is a Delaware corporation and its securities are trading on Nasdaq, it is currently expected that Arena will be subject to the 1% Excise Tax with respect to any redemptions of its Public Shares after 2022 that are treated as repurchases for this purpose. Accordingly, the Board believes that there is a risk that redemptions of Public Stock in connection with a liquidation of Arena could be subject to the 1% Excise Tax if they were to occur in 2023. In addition, it is uncertain whether, and/or to what extent, the 1% Excise Tax could apply to any redemptions of Arena’s Public Shares in connection with the consummation of an initial business combination in 2023 if Arena were able to consummate an initial business combination by the Original Termination Date. The 1% Excise Tax is imposed on the repurchasing corporation itself, not the stockholders from which stock is repurchased. That said, the imposition of the 1% Excise Tax could reduce the amount of cash available to Arena for effecting the redemptions of Public Shares in 2023 such that redeeming holders of Public Shares may receive a per-share redemption amount that is lower than what they would otherwise be entitled to receive.

The Charter currently provides that Arena has until the Original Termination Date to complete its initial business combination and, if Arena 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, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Board believes that the current provisions of the Charter above were included to protect Arena’s stockholders from having to sustain their investment for an unreasonably long period if Arena 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 unlikely that Arena would be able to complete an initial business combination before the Original Termination Date, Arena is not permitted by the Charter 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 the rights of holders of Class A Common Stock.

The purpose of the Charter Amendment Proposal is to change the Original Termination Date to the Amended Termination Date such that (i) the Public Stockholders may elect to redeem all or a portion of their

Public Shares in exchange for their pro rata portion of the funds held in the Trust Account in connection with the approval of the Charter Amendment Proposal, without having to wait for approximately another two months to do so while continuing to earn minimal interest, if any, on the funds during such waiting period and (ii) Arena will be obligated to, pursuant to a plan of complete liquidation, redeem all remaining issued and outstanding Public Shares not redeemed in connection with the Charter Amendment Proposal as promptly as reasonably possible but not more than ten business days after the Amended Termination Date and, subject to the approval of the Board and Arena’s remaining stockholders after completion of the Early Liquidation, liquidate and dissolve as promptly as reasonably possible after completion of the Early Liquidation, which will allow Arena to return the funds to its Public Stockholders earlier that currently contemplated under the Charter and enable these stockholders to recover their investment sooner. Arena also plans to voluntarily delist the Class A Common Stock from Nasdaq as soon as practicable after completion of the Early Liquidation, subject to the rules of Nasdaq and the Charter.

The Charter Amendment Proposal also removes the requirement that the Company have minimum net tangible assets of at least $5,000,001. This is a protective provision that is intended to ensure that the Company complies with Rule 419 under the Securities Act. A failure to comply could, among other things, result in the Company being unable to maintain the listing for its securities on any national securities exchange. The Board believes that a decision by stockholders to approve the Early Liquidation obviates the need for such compliance and, in fact, this requirement could have the unintended consequences of frustrating a liquidation and dissolution that was otherwise sought by stockholders.

The Charter Amendment Proposal further provides that the Company may remove up to $100,000 of interest earned on the Trust Account for dissolution expenses prior to redeeming the Public Shares in connection with the Special Meeting.

After careful consideration of all relevant factors, including, but not limited to, the time value of money, existing market conditions, the possible imposition of the 1% Excise Tax under the IR Act on redemptions by Arena of Public Shares in 2023, and the conclusion that it is unlikely that Arena would be able to complete an initial business combination before the Original Termination Date, the Board has determined that the Charter Amendment Proposal is in the best interests of Arena and its stockholders and recommends that you vote or give instruction to vote “FOR” the Charter Amendment Proposal. If the Early Termination Proposal is approved and the Early Termination Amendment is implemented, such approval and amendment are intended to constitute the adoption of a plan of complete liquidation of the Company for U.S. federal income tax purposes.

If the Charter Amendment Proposal Is Not Approved

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, Arena 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 Public Shares in consideration of at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as

stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

If the Charter Amendment Proposal Is Approved

If the Charter Amendment Proposal is approved and implemented, following redemption of the Public Shares by Public Stockholders who properly exercised their redemption rights in connection with the Charter Amendment Proposal, because Arena will not be able to complete an initial business combination by the Amended Termination Date, Arena will (i) after the Amended Termination Date, cease all operations, except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days after the thereafter, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes, divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Arena also plans to voluntarily delist the Class A Common Stock from Nasdaq as soon as practicable after completion of the Early Liquidation, subject to the rules of Nasdaq and the Charter.

Redemption Rights

Please see “Redemptions Rights” in the “Special Meeting of Arena Stockholders” section.

Vote Required for Approval

The approval of the Charter Amendment Proposal requires the affirmative vote of at least 50% of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class. As of the date of this proxy statement, the Initial Stockholder Shares represent 20.0% of the Company’s outstanding Common Stock. Accordingly, in addition to the Initial Stockholder Shares, the Company will need 6,468,750 Public Shares (or approximately 37.5% of the outstanding Class A Common Stock) to be voted in favor of the Charter Amendment Proposal to approve such proposal. Approval of the Charter Amendment Proposal is a condition to the implementation of the Early Liquidation.

Abstentions will be considered present for the purposes of establishing a quorum and, as a matter of Delaware law, will constitute votes “AGAINST” the approval of the Charter Amendment Proposal at the Special Meeting.

Recommendation of the Board

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

PROPOSAL NO. 2 — THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal asks stockholders to adjourn the Special Meeting to a later date or dates, if necessary, 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 the Company’s Common Stock to approve the Charter Amendment Proposal or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate.

Consequences if the Adjournment Proposal Is Not Approved

If the Adjournment Proposal is not approved by Arena’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 the Company’s Common Stock to approve the Charter Amendment Proposal. In such event, the Charter Amendment Proposal would not be approved.

Vote Required for Approval

In addition to the Initial Stockholder Shares, the approval of the Adjournment Proposal will require the affirmative vote of at least 6,468,751 shares of Common Stock held by the Public Stockholders (or approximately 37.5% of the outstanding Class A Common Stock) if all shares of Common Stock are represented at the Special Meeting, and the affirmative vote of at least 1,078,126 Public Shares (or approximately 6.3% of the Class A Common Stock) if only such shares as are required to establish a minimum quorum are represented at the Special Meeting.

Recommendation of the Board

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR REDEEMING STOCKHOLDERS

The following discussion is a summary of certain material U.S. federal income tax considerations for U.S. Holders and Non-U.S. Holders (each as defined below, and together, “Holders”) that have their Public Shares redeemed for cash, either pursuant to an exercise of redemption rights in connection with the Charter Amendment Proposal or in connection with the Company’s liquidation in the event the Charter Amendment Proposal is approved, and the expiration of public warrants in such event. This section applies only to Holders that hold their units or Public Shares and public warrants as “capital assets” for U.S. federal income tax purposes (generally, property held for investment). For purposes of this discussion, because the components of a unit are generally separable at the option of the holder, the holder of a unit generally should be treated, for U.S. federal income tax purposes, as the owner of the underlying Public Share and public warrant components of the unit, and the discussion below with respect to actual Holders of Public Shares and public warrants also should apply to holders of units (as the deemed owners of the underlying Public Shares and public warrants that constitute the units).

This discussion is limited to U.S. federal income tax considerations and does not address any estate or gift or other U.S. non-income tax considerations or considerations arising under the tax laws of any U.S. state or local or non-U.S. jurisdiction. This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances, including the alternative minimum tax, the Medicare tax on certain investment income and the different consequences that may apply if you are subject to special rules under U.S. federal income tax law that apply to certain types of investors, such as:

•

our founders, sponsors, officers or directors or other holders of our Class B common stock or private placement warrants or their affiliates;

•

banks, financial institutions or financial services entities;

•

broker-dealers;

•

taxpayers that are subject to the mark-to-market accounting rules with respect to the Public Shares or public warrants;

•

tax-exempt entities;

•

governments or agencies or instrumentalities thereof;

•

insurance companies;

•

regulated investment companies or real estate investment trusts;

•

partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) or pass-through entities (including S Corporations), or persons that hold the Public Shares or public warrants through such partnerships or pass-through entities;

•

U.S. expatriates or former long-term residents of the United States;

•

persons that actually or constructively own five percent or more (by vote or value) of Arena’s shares (except as specifically provided below);

•

persons that acquired their Public Shares or public warrants pursuant to an exercise of employee share options, in connection with employee share incentive plans or otherwise as compensation;

•

persons that hold their Public Shares or public warrants as part of a straddle, constructive sale, hedge, wash sale, conversion or other integrated or similar transaction;

•

U.S. Holders (as defined below) whose functional currency is not the U.S. dollar; or

•

“specified foreign corporations” (including “controlled foreign corporations”), “passive foreign investment companies” or corporations that accumulate earnings to avoid U.S. federal income tax.

If a partnership (or any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Public Shares or public 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 any Public Shares or public warrants 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 Charter Amendment Proposal.

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), proposed, temporary and final Treasury Regulations promulgated thereunder, and judicial and administrative interpretations thereof, all as of the date hereof. All of the foregoing is subject to change, which change could apply retroactively and could affect the tax considerations described herein.

The Company has not sought, and does not intend to seek, any rulings from the U.S. Internal Revenue Service (the “IRS”) as to any U.S. federal income tax considerations 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 IS ONLY A SUMMARY OF CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE REDEMPTION OF PUBLIC SHARES AND EXPIRATION OF PUBLIC WARRANTS AS A RESULT OF THE CHARTER AMENDMENT PROPOSAL. EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE REDEMPTION OF PUBLIC SHARES AND EXPIRATION OF PUBLIC WARRANTS AS A RESULT OF THE CHARTER AMENDMENT PROPOSAL, INCLUDING THE APPLICABILITY AND EFFECTS OF U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX LAWS.

For purposes of this discussion, because any unit consisting of one Public Share and one-third (1/3) of one warrant (with a whole warrant representing the right to acquire one share of Class A Common Stock) is separable at the option of the holder, the Company is treating each Public Share and public warrant held by a holder in the form of a single unit as separate instruments and is assuming that the unit itself will not be treated as an integrated instrument. Accordingly, the separation of the units in connection with the exercise of redemption rights generally should not be a taxable event for U.S. federal income tax purposes. This position is not free from doubt, and no assurance can be given that the IRS would not assert, or that a court would not sustain, a contrary position.

U.S. Holders

As used herein, a “U.S. Holder” is a beneficial owner of a Public Share or public warrant who or that is, for U.S. federal income tax purposes:

•

an individual who is a 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 United States persons (within the meaning of the Code) 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 United States person.

Redemption of Public Shares

Redemption of Public Shares Pursuant to An Exercise of Redemption Rights

The redemption of a U.S. Holder’s Public Shares pursuant to an exercise of redemption rights described in this proxy statement is likely to be treated as a distribution of cash to such U.S. Holder in connection with the complete liquidation of the Company for U.S. federal income tax purposes. However, it is possible that such redemption could be treated as a separate redemption transaction not in connection with the complete liquidation of the Company for U.S. federal income tax purposes.

If the redemption of a U.S. Holder’s Public Shares pursuant to an exercise of redemption rights described in this proxy statement is treated as a distribution to such U.S. Holder in complete liquidation of the Company, such distribution will be treated as a payment received in exchange for such Public Shares under Section 331 of the Code and taxable to the U.S. Holder as described below under the section entitled “—Redemption of Public Shares in Connection with the Company’s Liquidation” and “—Taxation of Redemption of Public Shares as a Sale of Public Shares.”

If a redemption of a U.S. Holder’s Public Shares pursuant to an exercise of redemption rights described in this proxy statement is not treated as a distribution to such holder in complete liquidation of the Company (a “non-liquidating redemption”), the U.S. federal income tax consequences to a U.S. Holder of Public Shares will instead depend on whether the non-liquidating redemption qualifies as a sale of Public Shares under Section 302 of the Code or is treated as a distribution under Section 301 of the Code. If the non-liquidating redemption qualifies as a sale of Public Shares by a U.S. Holder, the tax consequences to such U.S. Holder are as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Sale of Public Shares.” If the non-liquidating redemption does not qualify as a sale of Public Shares, a U.S. Holder will be treated as receiving a corporate distribution with the tax consequences to such U.S. Holder as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Corporate Distribution.”

Whether a non-liquidating redemption of Public Shares qualifies for sale treatment under Section 302 of the Code will depend largely on the total number of shares of the Company’s stock treated as held by the redeemed U.S. Holder before and after the non-liquidating redemption (including any stock of the Company treated as constructively owned by the U.S. Holder as a result of owning public warrants) relative to all of the stock of the Company outstanding both before and after the non-liquidating redemption. A non-liquidating redemption of Public Shares generally will be treated as a sale of Public Shares (rather than as a corporate distribution) if the non-liquidating redemption (1) is “substantially disproportionate” with respect to the U.S. Holder, (2) results in a “complete redemption” of the U.S. Holder’s interest in the Company or (3) is “not essentially equivalent to a dividend” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests result in a non-liquidating redemption qualifying for sale treatment, a U.S. Holder takes into account not only shares of the Company’s stock actually owned by the U.S. Holder, but also shares of the Company’s stock that are constructively owned by it under certain attribution rules set forth in the Code. A U.S. Holder may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any stock that the U.S. Holder has a right to acquire by exercise of an option, which would generally include Public Shares which could be acquired pursuant to the exercise of public warrants.

In order to meet the substantially disproportionate test, the percentage of the Company’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately following the non-liquidating redemption of Public Shares must, among other requirements, be less than eighty percent (80%) of the percentage of the Company’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately before the non-liquidating redemption and less than 50 percent of the total combined voting power of the Company. There will be a complete redemption of a U.S. Holder’s interest if either (1) all of the Public Shares actually and constructively owned by the U.S. Holder are redeemed or (2) all of the Public Shares actually

owned by the U.S. Holder are redeemed and the U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the U.S. Holder does not constructively own any other Public Shares (including any stock constructively owned by the U.S. Holder as a result of owning public warrants). The non-liquidating redemption of Public Shares will not be essentially equivalent to a dividend if the non-liquidating redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in the Company. Whether the non-liquidating redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in the Company will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation where such stockholder exercises no control over corporate affairs may constitute such a “meaningful reduction.”

If none of the foregoing tests is satisfied, then a non-liquidating redemption of Public Shares will be treated as a corporate distribution to the redeemed U.S. Holder and the tax effects to such a U.S. Holder will be as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Corporate Distribution.” After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed Public Shares will be added to the U.S. Holder’s adjusted tax basis in its remaining shares of the Company’s stock or, if it has none, to the U.S. Holder’s adjusted tax basis in its public warrants or possibly in other shares of the Company’s stock constructively owned by it.

Whether a non-liquidating redemption satisfies one or more of the foregoing tests will generally depend upon a U.S. Holder’s particular circumstances. This determination may, in appropriate circumstances, take into account other acquisitions or dispositions of the Company’s securities that occur as part of a plan that includes such redemption, including dispositions of the Company’s securities that occur in connection with its liquidation.

U.S. Holders who actually or constructively own at least five percent (5%) by vote or value (or, if the Public Shares are not then considered to be publicly traded, at least one percent (1%) by vote or value) or more of the total outstanding Company stock may be subject to special reporting requirements with respect to a non-liquidating redemption of Public Shares, and such holders should consult with their tax advisors with respect to their reporting requirements.

Redemption of Public Shares in Connection with the Company’s Liquidation

A U.S. Holder’s receipt of cash for its Public Shares in connection with the Company’s liquidation is expected to be treated as a distribution to such holder in complete liquidation of the Company for U.S. federal income tax purposes, with such distribution treated as a payment received in exchange for such Public Shares under Section 331 of the Code. The consequences of such a redemption to a U.S. Holder are generally as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Sale of Public Shares.” U.S. Holders should consult with their tax advisors regarding any special reporting requirements that may be applicable.

Taxation of Redemption of Public Shares Treated as a Corporate Distribution

If the redemption of a U.S. Holder’s Public Shares is treated as a corporate distribution, as discussed above under the section entitled “—Redemption of Public Shares,” the amount of cash received in the redemption generally will constitute a dividend for U.S. federal income tax purposes to the extent paid from the Company’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If the redemption is treated as a corporate distribution treated as dividend, such dividends paid to a redeeming U.S. Holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends paid to a non-corporate redeeming U.S. Holder generally will constitute “qualified dividends” that will be subject to tax at the maximum tax rate accorded to long-term capital gains. It is

unclear whether the redemption rights with respect to the Public Shares 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.

Distributions in excess of the Company’s current and accumulated earnings and profits 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 be treated as gain realized on the sale of Public Shares and will be treated as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Sale of Public Shares.”

Taxation of Redemption of Public Shares Treated as a Sale of Public Shares

If the redemption of a U.S. Holder’s Public Shares is treated as a sale, as discussed above under the section entitled “—Redemption of Public Shares,” a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash received in the redemption and the U.S. Holder’s adjusted tax basis in the Public Shares redeemed. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the Public Shares so disposed of exceeds one year. Long-term capital gains recognized by non-corporate U.S. Holders generally will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

U.S. Holders who hold different blocks of Public Shares (including as a result of holding different blocks of Public Shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE TAX CONSEQUENCES TO THEM OF A REDEMPTION OF ALL OR A PORTION OF THEIR PUBLIC SHARES PURSUANT TO AN EXERCISE OF REDEMPTION RIGHTS DESCRIBED IN THIS PROXY STATEMENT OR IN CONNECTION WITH OUR LIQUIDATION, INCLUDING ANY SPECIAL REPORTING REQUIREMENTS.

Expiration of a Public Warrant

If the Charter Amendment Proposal is approved, the public warrants, which do not become exercisable unless the Company completes 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 limitations.

Non-U.S. Holders

As used herein, a “Non-U.S. Holder” is a beneficial owner of a Public Share or public warrant who is not a U.S. Holder.

Redemption of Public Shares

Redemption of Public Shares Pursuant to An Exercise of Redemption Rights

The U.S. federal income tax consequences to a Non-U.S. Holder of Public Shares that exercises its redemption rights to receive cash from the Trust Account in exchange for all or a portion of its Public Shares will depend on whether the redemption is treated as a sale of the Public Shares redeemed or as a corporate distribution on the Public Shares, as described above under “U.S. Holders — Redemption of Public Shares — Redemption of Public Shares Pursuant to An Exercise of Redemption Rights.” If such a redemption is treated as a sale of Public Shares, the U.S. federal income tax consequences to the Non-U.S. Holder will be as described

below under “—Taxation of Redemption of Public Shares Treated as a Sale of Public Shares.” If such a redemption is not treated as a sale of Public Shares, the Non-U.S. Holder will be treated as receiving a corporate distribution, the U.S. federal income tax consequences of which are described below under “—Taxation of Redemption of Public Shares as a Corporate Distribution.”

Because it may not be certain at the time a Non-U.S. Holder is redeemed whether such Non-U.S. Holder’s redemption will be treated as a sale of shares or a corporate distribution, and because such determination may depend in part on a Non-U.S. Holder’s particular circumstances, the applicable withholding agent may not be able to determine whether (or to what extent) a Non-U.S. Holder is treated as receiving a dividend for U.S. federal income tax purposes. Therefore, the applicable withholding agent may withhold tax at a rate of thirty percent (30%) (or such lower rate as may be specified by an applicable income tax treaty) on the gross amount of any consideration paid to a Non-U.S. Holder in redemption of such Non-U.S. Holder’s Public Shares, unless (a) the applicable withholding agent has established special procedures allowing Non-U.S. Holders to certify that they are exempt from such withholding tax and (b) such Non-U.S. Holders are able to certify that they meet the requirements of such exemption (e.g., because such Non-U.S. Holders are not treated as receiving a dividend under the Section 302 tests described above under the section entitled “U.S. Holders — Redemption of Public Shares — Redemption of Public Shares Pursuant to An Exercise of Redemption Rights”). However, there can be no assurance that any applicable withholding agent will establish such special certification procedures. If an applicable withholding agent withholds excess amounts from the amount payable to a Non-U.S. Holder, such Non-U.S. Holder generally may obtain a refund of any such excess amounts by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their own tax advisors regarding the application of the foregoing rules in light of their particular facts and circumstances and any applicable procedures or certification requirements.

Redemption of Public Shares in Connection with the Company’s Liquidation

A Non-U.S. Holder’s receipt of cash for its Public Shares in connection with the Company’s liquidation is expected to be treated as a distribution to such holder in complete liquidation of the Company for U.S. federal income tax purposes, 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 to a Non-U.S. Holder are generally as described below under the section entitled “—Taxation of Redemption of Public Shares Treated as a Sale of Public Shares.”

Taxation of Redemption of Public Shares as a Corporate Distribution

In general, any distributions made to a Non-U.S. Holder of Public Shares, to the extent paid out of the Company’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, the Company will be required to withhold tax from the gross amount of the dividend at a rate of thirty percent (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). Any 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 Public Shares and, to the extent such distribution exceeds the Non-U.S. Holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Public Shares, which will be treated as described below under “—Taxation of Redemption of Public Shares as a Sale of Public Shares.” In addition, if the Company determines that it is likely to be classified as a “United States real property holding corporation” (see “—Taxation of Redemption of Public Shares as a Sale of Public Shares” below), the applicable withholding agent may withhold fifteen (15%) of any distribution that exceeds the Company’s current and accumulated earnings and profits.

The withholding tax generally does not apply to dividends paid to a Non-U.S. Holder that are effectively connected with such Non-U.S. Holder’s conduct of a trade or business within the United States, provided that

such Non-U.S. Holder furnishes an IRS Form W-8ECI. Instead, the effectively connected dividends will be subject to regular U.S. federal income tax as if the Non-U.S. Holder were a U.S. resident, subject to an applicable income tax treaty providing otherwise. A Non-U.S. Holder that is treated as a foreign corporation for U.S. federal income tax purposes receiving effectively connected dividends may also be subject to an additional “branch profits tax” imposed at a rate of thirty percent (30%) (or a lower applicable treaty rate).

Taxation of Redemption of Public Shares as a Sale of Public Shares

A Non-U.S. Holder generally will 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 as described above under “—Redemption of Public Shares,” unless:

(i)

the gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States (and, under certain income tax treaties, is attributable to a United States permanent establishment or fixed base maintained by the Non-U.S. Holder);

(ii)

such Non-U.S. Holder is an individual who was present in the United States for 183 days or more in the taxable year of such disposition (as such days are calculated pursuant to Section 7701(b)(3) of the Code) and certain other requirements are met; or

(iii)

the Company is or has been a “United States real property holding corporation” (as defined below) 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 Non-U.S. Holder’s holding period for the applicable security being disposed of, except, in the case where Public Shares are “regularly traded” on an “established securities market” (as such terms are defined under applicable Treasury Regulations), the Non-U.S. Holder is disposing of Public Shares and has owned, whether actually or based on the application of constructive ownership rules, five percent (5%) or less of Public Shares at all times within the shorter of the five-year period preceding such disposition of Public Shares or such Non-U.S. Holder’s holding period for such Public Shares. There can be no assurance that Public Shares are or have been treated as regularly traded on an established securities market for this purpose. It is unclear how the rules for determining the five percent (5%) threshold for this purpose would be applied with respect to Public Shares, including how a Non-U.S. Holder’s ownership of public warrants impacts the five percent (5%) threshold determination with respect to Public Shares. Non-U.S. Holders should consult their own tax advisors regarding the application of the foregoing rules in light of their particular facts and circumstances.

Unless an applicable treaty provides otherwise, gain described in the first bullet point above will 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 treated as a foreign corporation for U.S. federal income tax purposes may also be subject to an additional “branch profits tax” imposed at a thirty percent (30%) rate (or a lower applicable income tax treaty rate).

If the second bullet point applies to a Non-U.S. Holder, such Non-U.S. Holder generally will be subject to U.S. tax on such Non-U.S. Holder’s net capital gain for such year (including any gain realized in connection with the redemption) at a tax rate of thirty percent (30%) (or a lower applicable tax treaty rate).

If the third bullet point above applies to a Non-U.S. Holder, gain recognized by such holder will be subject to tax at generally applicable U.S. federal income tax rates. In addition, the Company may be required to withhold U.S. federal income tax at a rate of fifteen percent (15%) of the amount realized upon such redemption. The Company will be classified as a “United States real property holding corporation” 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. It is not expected that the Company would be a United States real property holding corporation in the immediate foreseeable future. However, such determination is factual in nature and subject to change and no assurance can be provided as to whether the Company would be treated as a United States real property holding corporation in any year.

Non-U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them in respect of any loss recognized on a redemption of Public Shares that is treated as a sale for U.S. federal income tax purposes.

Expiration of a Public Warrant

If the Charter Amendment Proposal is approved, the public warrants, which do not become exercisable unless Arena completes 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. Non-U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them in respect of any loss recognized on the expiration of their public warrants.

Foreign Account Tax Compliance Act

Section 1471 through 1474 of the Code and the Treasury regulations and administrative guidance promulgated thereunder (commonly referred to as “FATCA”) generally impose withholding at a rate of thirty percent (30%) on payments of dividends (including constructive dividends) on Public Shares to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied by, or an exemption applies to, the payee (typically certified as to by the delivery of a properly completed IRS Form W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of such withholding taxes, and a Non-U.S. Holder might be required to file a U.S. federal income tax return to claim such refunds or credits. Thirty percent (30%) withholding under FATCA was scheduled to apply to payments of gross proceeds from the sale or other disposition of property that produces U.S.-source interest or dividends beginning on January 1, 2019, but on December 13, 2018, the IRS released proposed regulations that, if finalized in their proposed form, would eliminate the obligation to withhold on gross proceeds. Such proposed regulations also delayed withholding on certain other payments received from other foreign financial institutions that are allocable, as provided for under final Treasury Regulations, to payments of U.S.-source dividends, and other fixed or determinable annual or periodic income. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations are issued. However, there can be no assurance that final Treasury Regulations will provide the same exceptions from FATCA withholding as the proposed Treasury Regulations.

Non-U.S. Holders should consult their tax advisors regarding the effects of FATCA on their redemption of Public Shares.

ALL NON-U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE TAX CONSEQUENCES TO THEM OF A REDEMPTION OF ALL OR A PORTION OF THEIR PUBLIC SHARES PURSUANT TO AN EXERCISE OF REDEMPTION RIGHTS DESCRIBED IN THIS PROXY STATEMENT OR IN CONNECTION WITH OUR LIQUIDATION, INCLUDING ANY SPECIAL REPORTING REQUIREMENTS.

Information Reporting and Backup Withholding

In general, proceeds received from the exercise of redemption rights will be subject to backup withholding for a non-corporate U.S. Holder that:

•

fails to provide an accurate taxpayer identification number;

•

is notified by the IRS regarding a failure to report all interest or dividends required to be shown on his or her federal income tax returns; or

•

in certain circumstances, fails to comply with applicable certification requirements.

A Non-U.S. Holder generally may eliminate the requirement for information reporting and backup withholding by providing certification of its non-U.S. status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Any amount withheld under these rules will be creditable against the U.S. Holder’s or Non-U.S. Holder’s U.S. federal income tax liability or refundable to the extent that it exceeds this liability, provided that the required information is timely furnished to the IRS and other applicable requirements are met.

As previously noted above, the foregoing discussion of certain U.S. federal income tax consequences is included for general information purposes only and is not intended to be, and should not be construed as, legal or tax advice to any stockholder. The Company once again urges you to consult with your own tax adviser to determine the particular tax consequences to you (including the application and effect of any U.S. federal, state, local or foreign income or other tax laws) of the Charter Amendment Proposal.

BUSINESS OF ARENA AND CERTAIN INFORMATION ABOUT ARENA

Overview

We are a blank check company incorporated as a Delaware corporation on January 26, 2021 and 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.

In February 2021, we issued 5,750,000 founder shares to our Sponsor for an aggregate purchase price of $25,000 in cash, or approximately $0.004 per share. In March 2021, our Sponsor sold 456,000 founder shares each to Cowen Investments II LLC and Intrepid Financial Partners, L.L.C. On March 19, 2021, our Sponsor transferred 25,000 founder shares to each of Marc McCarthy and James Crockard III. On October 4, 2021, we effected a share contribution back to capital resulting in our Initial Stockholders holding 4,312,500 shares of our Class B Common Stock.

On November 15, 2021, we consummated the IPO of 17,250,000 units (including 2,250,000 units issued upon exercise in full by the underwriters of their option to purchase additional units) at $10.00 per unit, generating gross proceeds of $172,500,000. Each unit consists of one share of Class A Common Stock and one-half of one redeemable warrant. Each whole warrant entitles the holder to purchase one share of Class A Common Stock at an exercise price of $11.50 per whole share.

Simultaneously with the consummation of the IPO, certain of the Initial Stockholders purchased an aggregate of 5,450,00 private placement warrants (including 450,000 private placement warrants issued in connection with the exercise in full by the underwriters of their option to purchase additional units), at a price of $1.00 per private placement warrant, generating gross proceeds of $5,450,000. Furthermore, simultaneously with the consummation of the IPO, certain of the Initial Stockholders lent us an aggregate amount of $3,450,000 (the “Initial Stockholder Loans”).

A total of approximately $175.9 million, comprised of the net proceeds from the IPO (which amount includes $14,490,000 of the underwriters’ deferred discount), the proceeds of the sale of the private placement warrants and the proceeds from the Initial Stockholder Loans, was placed in a U.S.-based Trust Account at J.P. Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee.

The funds held in the Trust Account are invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in money market funds meeting the conditions of Rule 2a-7 of the Investment Company Act which invest only in direct U.S. government treasury obligations, until the earlier of• (i) the consummation of an initial business combination or (ii) the distribution of the Trust Account, as described below.

The Charter currently provides that Arena has until the Original Termination Date to complete its initial business combination and, if Arena 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, redeem the Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to Arena to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Stockholders as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

This proxy statement is available without charge to stockholders of Arena upon written or oral request. If you would like additional copies of this proxy statement or if you have questions about the proposals to be presented at the Special Meeting, you should contact Arena in writing at Arena Fortify Acquisition Corp, 405 Lexington Avenue, 59th Floor, New York, NY, or by telephone at (212) 612-3205.

HOUSEHOLDING INFORMATION

Unless Arena has received contrary instructions, Arena may send a single copy of this proxy statement to any household at which two or more stockholders reside if Arena 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 Arena’s expenses. However, if stockholders prefer to receive multiple sets of Arena’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 Arena’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 Arena Fortify Acquisition Corp., 405 Lexington Avenue, 59th Floor, New York, NY 10174, to inform us of his, her or its request; or

•

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