NOTICE OF SPECIAL MEETING

TO BE HELD ON DECEMBER 6, 2023

TO THE STOCKHOLDERS OF ALTITUDE ACQUISITION CORP.:

You are cordially invited to attend the special meeting (the “Special Meeting”) of stockholders of Altitude Acquisition Corp. (the “Company,” “we,” “us” or “our”), to be held at 10 a.m. Eastern Time, on December 6, 2023. The Special Meeting will be held virtually, at https://www.cstproxy.com/altitudeac/sm2023. At the Special Meeting, the stockholders will consider and vote upon the following proposals:

Each of the Extension Amendment Proposal and the Adjournment Proposal is more fully described in the accompanying proxy statement.

The Special Meeting will be a virtual meeting. You will be able to attend and participate in the Special Meeting online by visiting https://www.cstproxy.com/altitudeac/sm2023. Please see “Questions and Answers about the Special Meeting — How do I attend the Special Meeting?” for more information.

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

If the Extension Amendment Proposal is approved, the Extension Amendment would allow us, without another stockholder vote, to elect to extend the Extended Date on a monthly basis 3 additional times until March 11, 2024, or a total of up to 3 months after the Current Outside Date by resolution of the Company’s board of directors (the “Board”).

As previously disclosed, on April 23, 2023, the Company entered into the Agreement and Plan of Merger (the “Picard Business Combination Agreement”) by and among the Company, Altitude Merger Sub I, Inc., a Delaware corporation and a direct, wholly owned subsidiary of Altitude (“Merger Sub”), Altitude Merger Sub II, LLC a Delaware limited liability company and a direct wholly owned subsidiary of Altitude (“Merger Sub II” and together with Merger Sub, the “Merger Subs”), Picard Medical Inc. (“Picard”) and Hunniwell Picard I, LLC, solely in its capacity as the representative, agent and attorney-in-fact of the securityholders of Picard. Pursuant to the Picard Business Combination Agreement, and upon the closing of the transactions contemplated therein, the Company will become the holding company for Picard’s business (the transactions contemplated by the Picard Business Combination Agreement, the “Picard Business Combination”). The purpose of the Extension Amendment Proposal is to provide the Company with sufficient time to complete the Picard Business Combination.

The Company’s prospectus for its initial public offering (the “IPO”) and its charter initially provided that the Company had until June 11, 2022, or 18 months after the closing date of its IPO, to complete a business combination. On June 10, 2022, the Company’s stockholders approved an amendment to the charter to provide that it would have until October 11, 2022 to complete a business combination. On October 6, 2022, the

Company’s stockholders approved a second amendment to the charter to provide that it would have until April 11, 2023 to complete a business combination. On April 7, 2023 the Company’s stockholders approved a third amendment to the charter to provide that it would have until the Current Outside Date. The Board currently believes that there will not be sufficient time for the Company to consummate the Picard Business Combination by the Current Outside Date. The Company has filed a merger proxy with the Securities and Exchange Commission (“SEC”) but has not cleared all SEC comments and believes that it will not have enough time to satisfy all closing conditions and complete all actions required to consummate the Picard Business Combination before the Current Outside Date. Accordingly, the Board has determined that it is in the best interests of the Company and the Company’s stockholders to further extend the Current Outside Date to the Extended Date.

The Company is listed on The Nasdaq Capital Market (“Nasdaq”). Nasdaq rule IM-5101-2 requires that a special purpose acquisition company complete one or more business combinations within 36 months of the effectiveness of its IPO registration statement, which, in the case of the Company, would be December 8, 2023. The Extension to the Extended Date would extend the Company’s life beyond such 36-month deadline. As a result, the contemplated Extension does not comply with Nasdaq rules. We may be subject to suspension or delisting by Nasdaq if the Extension Amendment Proposal is approved and the Extension is implemented. For more information see “Risk Factors – The Extension contemplated by the Extension Amendment Proposal contravenes Nasdaq rules, and as a result, could lead Nasdaq to suspend trading in the Company’s securities or lead the Company to be delisted from Nasdaq.”

The purpose of the Adjournment Proposal is to allow the Company to adjourn the Special Meeting to a later date or dates or indefinitely or if we determine that additional time is necessary to effectuate the Extension.

The affirmative vote of 65% of the Company’s outstanding Class A common stock par value $0.0001 per share (the “common stock”), our only outstanding class of common stock, will be required to approve the Extension Amendment Proposal. Approval of the Adjournment Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person (including virtually) or by proxy at the Special Meeting.

As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal and Adjournment Proposal even if no other shares are voted in favor of such proposals.

Our Board has fixed the close of business on November 7, 2023 (the “Record Date”) as the record date for determining the Company’s stockholders entitled to receive notice of and vote at the Special Meeting and any adjournment thereof. Only holders of record of the Company’s common stock on the Record Date are entitled to have their votes counted at the Special Meeting or any adjournment thereof. On the Record Date, there were 8,834,645 outstanding shares of common stock. The Company’s warrants do not have voting rights in connection with any of the proposals being presented to our stockholders at the Special Meeting. A complete list of stockholders of record entitled to vote at the Special Meeting will be available for ten days before the Special Meeting at the Company’s principal executive offices for inspection by stockholders during ordinary business hours for any purpose germane to the Special Meeting.

If the Extension Amendment Proposal is approved, and the Extension is implemented, holders of our common stock included in the units sold in our initial public offering (the “public shares” and as to the holders the “public stockholders”) may elect to redeem their public shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established by the Company in connection with its IPO (the “trust account”), including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares, regardless of whether such public stockholders vote for or against the Extension Amendment Proposal, or do not vote at all, and regardless of whether they hold their shares on the Record Date. If the Extension is implemented, the remaining holders of public shares will retain the opportunity to have their public shares redeemed in conjunction with the consummation of the Picard Business Combination, subject to any limitations set forth in our charter, as

amended. In addition, public stockholders who do not elect to redeem their shares would be entitled to have their public shares redeemed for cash if the Company has not completed the Picard Business Combination by the Extended Date.

The Company estimates that the per-share price at which the public shares may be redeemed from cash held in the trust account will be approximately $10.34. The closing price of the Company’s common stock on Nasdaq on November 7, 2023, the Record Date, was $10.15. Accordingly, if the market price were to remain the same until the date of the Special Meeting, exercising redemption rights would result in a public stockholder receiving approximately $0.19 more than if such stockholder sold the public shares in the open market. The Company cannot assure public stockholders that they will be able to sell their public shares 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 securities when such stockholders wish to sell their shares.

If the Extension Amendment Proposal is not approved and the Company does not consummate the Picard Business Combination by the Current Outside Date, in accordance with our charter, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable and after setting aside up to $100,000 to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our 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, including the warrants included in the units sold in the IPO (the “public warrants”), which will expire worthless in the event the Company winds up.

You are not being asked to vote on the Picard Business Combination at this time. If the Extension is implemented and you do not elect to redeem your public shares in connection with the Extension, you will retain the right to vote on the Picard Business Combination when it is submitted to the public stockholders (provided that you are a stockholder on the record date for a meeting to consider the Picard Business Combination) and the right to redeem your public shares for a pro rata portion of the trust account in the event the Picard Business Combination is approved and completed or the Company has not consummated the Picard Business Combination by the Extended Date.

After careful consideration of all relevant factors, our Board has determined that the Extension Amendment Proposal, and, if presented, the Adjournment Proposal are advisable and recommends that you vote or give instruction to vote “FOR” each of the proposals.

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

I look forward to seeing you at the Special Meeting.

Your vote is important. If you are a stockholder of record, please sign, date and return your proxy card as soon as possible to make sure that your shares are represented at the Special Meeting. If you are a stockholder of record, you may also cast your vote virtually at the Special Meeting. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank how to vote your shares, or you may cast your vote virtually at the Special Meeting by obtaining a proxy from your brokerage firm or bank. Your abstention or failure to vote or instruct your broker or bank how to vote will have the same effect as voting against the Extension Amendment Proposal and will have no effect on the Adjournment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established. Important Notice Regarding the Availability of Proxy Materials for the Special Meeting of Stockholders to be held on December 6, 2023: This notice of meeting and the accompanying proxy statement are being made available on or about November 13, 2023 at https://www.cstproxy.com/altitudeac/sm2023.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST (1) IF YOU HOLD PUBLIC SHARES THROUGH UNITS, 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, (2) SUBMIT A WRITTEN REQUEST TO THE TRANSFER AGENT BY 5:00 P.M.

You are cordially invited to attend the special meeting (the “Special Meeting”) of stockholders of Altitude Acquisition Corp. (the “Company,” “we,” “us” or “our”), to be held at 10 a.m. Eastern Time, on December 6, 2023. The Special Meeting will be held virtually, at https://www.cstproxy.com/altitudeac/sm2023. At the Special Meeting, the stockholders will consider and vote upon the following proposals:

Approval of the Extension Amendment Proposal is a condition to implementing the Extension.

Our Board has fixed the close of business on November 7, 2023 (the “Record Date”) as the record date for determining the Company’s stockholders entitled to receive notice of and vote at the Special Meeting and any adjournment thereof.

There will be no redemption rights or liquidating distributions with respect to our warrants, including the warrants included in the units sold in the IPO (the “public warrants”), which will expire worthless in the event the Company winds up.

Our Sponsor, officers and directors (the “initial stockholders”) have agreed to waive their redemption rights with respect to their common stock held by them (the “founder shares”) and public shares in connection with a stockholder vote to approve an amendment to the Company’s charter.

If the Extension Amendment Proposal is approved, such approval will constitute consent for the Company to (i) remove from the trust account an amount (the “Withdrawal Amount”) equal to the number of public shares properly redeemed multiplied by the per-share price, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares and (ii) deliver to the holders of such redeemed public shares their portion of the Withdrawal Amount. The remainder of such funds shall remain in the trust account and be available for use by the Company to complete the Picard Business Combination on or before the Extended Date. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on the Picard Business Combination through the Extended Date if the Extension Amendment Proposal is approved.

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.

This proxy statement is dated November 13, 2023 and is first being mailed to stockholders on or about November 13, 2023.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should read carefully the entire proxy statement, including the annex to this proxy statement.

Q: Why am I receiving this proxy statement?

A: This proxy statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by our Board for use at the Special Meeting, or at any adjournments thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Special Meeting.

The Company is a blank check company formed in 2020 for the purpose of entering into a business combination with one or more businesses or entities. On December 11, 2020, the Company consummated its IPO of 30,000,000 units, each consisting of one share of Class A common stock and one-half of one redeemable warrant including the issuance of 3,900,000 units as a result of the partial exercise of the underwriters’ over-allotment option, at $10.00 per unit generating gross proceeds of $300,000,000. Simultaneously with the closing of the IPO, the Company consummated the sale of an aggregate of 8,000,000 private placement warrants (the “private placement warrants”) at a price of $1.00 per warrant in a private placement to our Sponsor, generating gross proceeds to the Company of $8,000,000.

Following the closing of the IPO on December 11, 2020, an amount of $300,000,000 ($10.00 per unit) from the net proceeds of the sale of the units in the IPO and the sale of the private placement warrants was placed in the trust account, which was invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. On December 5, 2022, to mitigate the risk of being viewed as operating as an unregistered investment company, we instructed Continental Trust Stock Transfer and Trust Company, the trustee with respect to the trust account, to liquidate the U.S. government treasury obligations or money market funds held in the trust account and thereafter to hold all funds in the trust account in an interest-bearing bank deposit account. Such funds will be held in trust until the earlier of: (a) the completion of the Company’s initial business combination, (b) the redemption of any public shares properly submitted in connection with a stockholder vote to amend the Company’s charter, and (c) the redemption of the Company’s public shares if the Company is unable to complete the initial business combination within the period provided in our charter. Like most blank check companies, our charter provides for the return of the IPO proceeds held in the trust account to the holders of shares of common stock sold in the IPO if there is no qualifying business combination(s) consummated on or before a certain date. In our case such date was initially June 11, 2022.

The Company was unable to complete a qualifying business combination by June 11, 2022 and on June 10, 2022, the Company’s stockholders approved an amendment to the charter to provide that the Company would have until October 11, 2022 to complete a business combination. In connection with such amendment, the Company offered public stockholders the right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 24,944,949 public shares exercised their right to redeem their shares at a redemption price of approximately $10.01 per share, or a total of $249,614,847 of the funds held in the Company’s trust account.

The Company was also unable to complete a qualifying business combination by October 11, 2022 and on October 6, 2022 the Company’s stockholders approved an amendment to the charter to provide that the Company would have until April 11, 2023 to complete a business combination. In connection with such amendment, the Company offered public stockholders the right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 3,382,949 public shares exercised their right to redeem

2

their shares at a redemption price of approximately $10.05 per share, or a total of $34,009,688.61 of the funds held in the Company’s trust account.

The Company was also unable to complete a business combination by April 11, 2023 and on April 7, 2023, the Company’s stockholders approved an amendment to the charter to provide that the Company would have until May 11, 2023 to complete a business combination which could be extended monthly until December 11, 2023. In connection with such amendment, the Company offered public stockholders the right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 337,457 public shares exercised their right to redeem their shares for approximately $10.08 per share, or a total of $3,401,567 of the funds held in the Company’s trust account.

Accordingly, as of the Record Date, the Company has approximately $13,798,537 of cash remaining in the trust account.

The Company entered into the Picard Business Combination Agreement on April 23, 2023, and is using its best efforts to complete the Picard Business Combination as soon as practicable. The Company has filed a merger proxy with the SEC but has not cleared all SEC comments and believes that it will not have enough time to satisfy all closing conditions and complete all actions required to consummate the Picard Business Combination before the Current Outside Date. The purpose of the Extension Amendment Proposal and, if necessary, the Adjournment Proposal, is therefore to provide sufficient time to complete the Picard Business Combination.

Q: What is being voted on?

A: You are being asked to vote on the following proposals:

Q: What are the purposes of the Extension Amendment Proposal and the Adjournment Proposal?

A: The purpose of the Extension Amendment Proposal is to provide the Company with sufficient time to complete the Picard Business Combination. The Company’s prospectus for its IPO and its charter initially provided that the Company had until June 11, 2022, or 18 months after the closing date of its IPO, to complete a business combination. On June 10, 2022, the Company’s stockholders approved an amendment to the charter to provide that it would have until October 11, 2022 to complete a business combination. On October 6, 2022, the Company’s stockholders approved a second amendment to the charter to provide that it would have until April 11, 2023 to complete a business combination. On April 7, 2023, the Company’s stockholders approved a third amendment to the charter to provide that it would have until the Current Outside Date to approve the business combination. The Company’s Board currently believes that there will not be sufficient time for the Company to consummate the Picard Business combination by the Current Outside Date.

The purpose of the Adjournment Proposal is to allow the Company to adjourn the Special Meeting to a later date or dates or indefinitely, if necessary or convenient, if we determine that additional time is necessary to effectuate the Extension.

Approval of the Extension Amendment Proposal is a condition to the implementation of the Extension. If the Extension is implemented, such approval will constitute consent for the Company to (i) remove from the trust account the Withdrawal Amount equal to the number of public shares properly redeemed multiplied by the per-share price, equal to the aggregate amount then on deposit in the trust account, including any interest earned

3

on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares and (ii) deliver to the holders of such redeemed public shares their portion of the Withdrawal Amount. The remainder of such funds shall remain in the trust account and be available for use by the Company to complete the Picard Business Combination or before the Extended Date. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on the Picard Business Combination through the Extended Date if the Extension Amendment Proposal is approved and the Extension is implemented.

If the Extension Amendment Proposal is approved and the Extension is implemented, the removal of the Withdrawal Amount from the trust account will reduce the amount held in the trust account. The Company cannot predict the amount that will remain in the trust account after such withdrawal and the amount remaining in the trust account may be only a fraction of the $13,798,537 (including interest but less the funds used to pay taxes) that was in the trust account as of the Record Date. In such event, the Company may still seek to obtain additional funds to complete the Picard Business Combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

If the Extension Amendment Proposal is not approved and the Company has not consummated the Picard Business Combination by the Current Outside Date, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable and after setting aside up to $100,000 to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our 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 the Picard Business Combination by the Current Outside Date.

You are not being asked to vote on the Picard Business Combination at this time. If the Extension is implemented and you do not elect to redeem your public shares now, you will retain the right to vote on the Picard Business Combination when and if it is submitted to the public stockholders (provided that you are a stockholder on the record date for a meeting to consider the Picard Business Combination) and the right to redeem your public shares for a pro rata portion of the trust account in the event the Picard Business Combination is approved and completed or the Company has not consummated the Picard Business Combination by the Extended Date.

Q: Why should I vote for the Extension Amendment Proposal?

A: Our Board believes stockholders will benefit from the Company consummating the Picard Business Combination. The Board believes that, given the Company’s expenditure of time, effort and money in seeking to consummate the Picard Business Combination, circumstances warrant providing public stockholders an opportunity to consider the Picard Business Combination. Accordingly, the Company is proposing the Extension Amendment Proposal to extend the date by which the Company must complete the Picard Business Combination, monthly, until the Extended Date.

Our charter provides that if our stockholders approve an amendment to our charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s public shares if the Company does not complete the Picard Business Combination by the Current Outside Date, the Company will provide our public stockholders with the opportunity to redeem all or a portion of their public shares upon such

4

approval at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. This charter provision was included to protect the Company’s stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable business combination in the timeframe contemplated by the charter.

Our Board recommends that you vote “FOR” the Extension Amendment Proposal, but expresses no opinion as to whether you should redeem your public shares.

Q: Why should I vote for the Adjournment Proposal?

A: If the Adjournment Proposal is presented and not approved by our stockholders, our Board may not be able to adjourn the Special Meeting to a later date or dates or indefinitely, if necessary or convenient if we determine that additional time is necessary to effectuate the Extension.

Our Board recommends that you vote “FOR” the Adjournment Proposal.

Q: How do the Company insiders intend to vote their shares?

A: The initial stockholders and their respective affiliates are expected to vote any common stock over which they have voting control (including any public shares owned by them) in favor of each of the proposals. The initial stockholders are not entitled to redeem the founder shares or any public shares held by them. On the Record Date, the Sponsor beneficially owned and was entitled to vote 7,500,000 founder shares, which represents approximately 85% of the Company’s issued and outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal and the Adjournment Proposal even if no public shares are voted in favor of such proposal.

In addition, the Sponsor or the Company’s officers, directors, advisors, or any of their respective affiliates, may purchase public shares in privately negotiated transactions or in the open market prior to or following the Special Meeting, although they are under no obligation to do so. Such public shares purchased by the Sponsor or its affiliates would be (a) purchased at a price no higher than the redemption price for the public shares, which is currently estimated to be $10.34 per share and (b) would not be (i) voted by such persons at the Special Meeting or (ii) redeemable by them. Any such purchases that are completed after the Record Date for the Special Meeting may include an agreement with a selling stockholder that such stockholder, for so long as it remains the record holder of the shares in question, will vote in favor of the proposals described in this proxy statement and/or will not exercise its redemption rights with respect to the shares so purchased. The purpose of such share purchases and other transactions would be to reduce the number of public shares that are redeemed. In the event that such purchases do occur, the purchasers may seek to purchase shares from stockholders who would otherwise have elected to redeem their shares for a portion of the trust account. Any such privately negotiated purchases may be effected at purchase prices that no higher than the per-share pro rata portion of the trust account. None of the initial stockholders, advisors or their respective affiliates may make any such purchases when they are in possession of any material non- public information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act.

Q: Does the Board recommend voting for the approval of the Extension Amendment Proposal and, if presented, the Adjournment Proposal?

A: Yes. After careful consideration of the terms and conditions of the proposals, the Board has determined that the Extension Amendment Proposal and, if presented, the Adjournment Proposal are in the best interests of the Company and its stockholders. The Board unanimously recommends that stockholders vote “FOR” the Extension Amendment Proposal and, if presented, the Adjournment Proposal.

Q: What vote is required to adopt the Extension Amendment?

A: The affirmative vote of 65% of the Company’s outstanding common stock will be required to approve the Extension Amendment Proposal.

As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal even if no other shares are voted in favor of such proposals.

If the Extension Amendment Proposal is approved, any holder of public shares may redeem all or a portion of their public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares, by following the procedures described elsewhere in this proxy statement.

Q: What vote is required to adopt the Adjournment Proposal?

A: Approval of the Adjournment Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person (including virtually) or by proxy at the Special Meeting. The Sponsor will be able to approve the Adjournment Proposal even if no public shares are voted in favor of such proposal.

Q: What happens if I sell my public shares or units before the Special Meeting?

A: The November 7, 2023 Record Date is earlier than the date of the Special Meeting. If you transfer your public shares, including those shares held as a constituent part of our units, after the Record Date, but before the Special Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Special Meeting. If you transfer your public shares prior to the Record Date, you will have no right to vote those shares at the Special Meeting. If you acquired your public shares after the Record Date, you will still have an opportunity to redeem them if you so decide.

Q: What if I don’t want to vote for the Extension Amendment Proposal and/or the Adjournment Proposal?

A: If you do not want the Extension Amendment Proposal to be approved, you must abstain, not vote, or vote against the proposal.

If you do not want the Adjournment Proposal to be approved, you must vote against the proposal. Abstentions and non-votes but will have no effect on the outcome of the Adjournment Proposal.

Q: Will you seek any further extensions to liquidate the trust account?

A: Other than the Extension as described in this proxy statement, the Company does not currently anticipate seeking any further extension to consummate the Picard Business Combination Agreement, although it may determine to do so in the future.

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

A: If the Extension Amendment Proposal is not approved and the Company has not consummated the Picard Business Combination by the Current Outside Date, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable and after setting aside up to

6

$100,000 to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our 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 the Picard Business Combination by the Current Outside Date.

The initial stockholders have agreed to waive their redemption rights with respect to their founder shares and public shares in connection with a stockholder vote to approve an amendment to the charter.

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

A: If the Extension Amendment Proposal is approved, the Company will file an amendment to the charter with the Secretary of State of the State of Delaware in the form of Annex A hereto. The Company will continue to attempt to consummate the Picard Business Combination until the Extended Date.

If the Extension Amendment Proposal is approved, the removal of the Withdrawal Amount from the trust account will reduce the amount remaining in the trust account and increase the percentage interest of the Company’s common stock held by the Sponsor through the founder shares.

Q: How are the funds in the trust account currently being held?

A: With respect to the regulation of special purpose acquisition companies like us (“SPACs”), on March 30, 2022, the SEC issued proposed rules (the “SPAC Rule Proposals”) relating to, among other items, the extent to which SPACs could become subject to regulation under the Investment Company Act of 1940, as amended (the “Investment Company Act”), including a proposed rule that would provide SPACs a safe harbor from treatment as an investment company if they satisfy certain conditions that limit a SPAC’s duration, asset composition, business purpose and activities.

There is currently uncertainty concerning the applicability of the Investment Company Act to a SPAC that has not entered into a definitive agreement within 18 months after the effective date of its IPO registration statement or that does not complete its initial business combination within 24 months after such date. The funds in the trust account, since the Company’s IPO, were held in U.S. government securities within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in money market funds meeting certain conditions of Rule 2a-7 of the Investment Company Act, to mitigate the risk of being viewed as operating as an unregistered investment company on December 5, 2022, we instructed Continental Trust Stock Transfer and Trust Company, the trustee with respect to the trust account, to liquidate the U.S. government treasury obligations or money market funds held in the trust account and thereafter to hold all funds in the trust account in an interest-bearing bank deposit account until the earlier of the consummation of a business combination or our liquidation. Following the liquidation of the trust account assets, we will likely receive minimal interest, if any, on the funds held in the trust account, which would reduce the dollar amount our public stockholders would have otherwise received upon any redemption or liquidation of the Company if the assets in the trust account had remained in U.S. government securities or money market funds. This means that the amount available for redemption will not increase in the future, and those stockholders who elect not to redeem their public shares in connection with the Extension Amendment will receive no more than the same per share amount, without additional interest, if they redeem their public shares in connection with a business combination or if the Company is liquidated in the future, in each case as compared with the per share amount they would have received if they had redeemed their public shares in connection with the Extension Amendment.

For more information, see the section entitled “Risk Factors – If we are deemed to be an investment company for purposes of the Investment Company Act, we may be forced to abandon our efforts to complete an initial business

7

combination and instead be required to liquidate the Company. To mitigate the risk of that result, on December 5, 2022 we instructed Continental Stock Transfer & Trust Company to liquidate the securities held in the trust account and instead hold all funds in the trust account in cash. As a result, following such change, we will likely receive minimal, if any, interest, on the funds held in the trust account, which would reduce the dollar amount that our public stockholders would have otherwise received upon any redemption or liquidation of the Company if the assets in the trust account had remained in U.S. government securities or money market funds.”

Q: If I do not redeem my shares now, would I still be able to vote on the Picard Business Combination and exercise my redemption rights with respect to the Picard Business Combination?

A: Yes. If you do not redeem your shares in connection with the Extension Amendment Proposal, then, assuming you are a stockholder as of the record date for voting on the Picard Business Combination, you will be able to vote on the Picard Business Combination when it is submitted to stockholders. You will also retain your right to redeem your public shares upon consummation of the Picard Business Combination, subject to any limitations set forth in the charter, as amended.

Q: When and where is the Special Meeting?

A: The Special Meeting will be held at 10 a.m. Eastern Time, on December 6, 2023, in virtual format. The Company’s stockholders may attend, vote and examine the list of stockholders entitled to vote at the Special Meeting by visiting https://www.cstproxy.com/altitudeac/sm2023 and entering the control number found on their proxy card, voting instruction form or notice included in their proxy materials. You may also attend the Special Meeting telephonically by dialing 1 800-450-7155 (toll-free within the United States and Canada) or +1 857-999-9155 (outside of the United States and Canada, standard rates apply). The pin number for telephone access is 8671310#, but please note that you will not be able to vote or ask questions if you choose to participate telephonically. The Special Meeting will be held in virtual meeting format only. You will not be able to attend the Special Meeting physically.

Q: How do I attend the virtual Special Meeting, and will I be able to ask questions?

A: If you are a registered stockholder, you received a proxy card from the Company’s transfer agent, Continental Stock Transfer & Trust Company (“transfer agent”). The form contains instructions on how to attend the virtual Special Meeting including the URL address, along with your control number. You will need your control number for access. If you do not have your control number, contact the transfer agent at the phone number or e-mail address below. The transfer agent support contact information is as follows: 917-262-2373, or email spacredemptions@continentalstock.com.

You can pre-register to attend the virtual meeting starting November 30, 2023 at 9:00 a.m. Eastern Time (five business days prior to the Special Meeting date). Enter the URL address into your browser https://www.cstproxy.com/altitudeac/sm2023, enter your control number, name and email address. Once you pre-register you can vote or enter questions in the chat box. At the start of the Special Meeting you will need to re-log in using your control number and will also be prompted to enter your control number if you vote during the Special Meeting.

Beneficial holders, who own their investments through a bank or broker, will need to contact the transfer agent to receive a control number. If you plan to vote at the Special Meeting you will need to have a legal proxy from your bank or broker or if you would like to join and not vote, the transfer agent will issue you a guest control number with proof of ownership. Either way you must contact the transfer agent for specific instructions on how to receive the control number. We can be contacted at the number or email address above. Please allow up to 72 hours prior to the Special Meeting for processing your control number.

If you do not have internet capabilities, you can listen only to the Special Meeting by dialing 1 800-450-7155, within the U.S. and Canada, or +1 857-999-9155 (standard rates apply) outside the U.S. and Canada; when prompted enter the pin number 8671310#. This is listen only, you will not be able to vote or enter questions during the Special Meeting.

Q: How do I vote?

A: If you are a holder of record of Company common stock, including those shares held as a constituent part of our units, you may vote virtually at the Special Meeting or by submitting a proxy for the Special Meeting. Whether or not you plan to attend the Special Meeting virtually, the Company urges you to vote by proxy to ensure your vote is counted. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope. You may still attend the Special Meeting and vote virtually if you have already voted by proxy.

If your shares of Company common stock, including those shares held as a constituent part of our units, are held in “street name” by a broker or other agent, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Special Meeting. However, since you are not the stockholder of record, you may not vote your shares virtually at the Special Meeting unless you request and obtain a valid proxy from your broker or other agent.

Q: How do I change my vote?

A: If you have submitted a proxy to vote your shares and wish to change your vote, you may do so by delivering a later-dated, signed proxy card prior to the date of the Special Meeting or by voting virtually at the Special Meeting. Attendance at the Special Meeting alone will not change your vote. You also may revoke your proxy by sending a notice of revocation to the Company at 400 Perimeter Center Terrace, Suite 151, Atlanta, Georgia 30346, Attn: Gary Teplis, President and Chief Executive Officer.

Q: How are votes counted?

A: Votes will be counted by the inspector of election appointed for the Special Meeting, who will separately count “FOR” and “AGAINST” votes, abstentions and broker non-votes for the Extension Amendment Proposal and Adjournment Proposal.

Approval of the Extension Amendment Proposal requires the affirmative vote of the stockholders holding at least 65% of the shares of common stock outstanding on the Record Date, voting together as a single class. Approval of the Adjournment Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person (including virtually) or by proxy at the Special Meeting. As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal and Adjournment Proposal even if no public shares are voted in favor of such proposals.

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

A: No. Under the rules governing banks and brokers who submit a proxy card with respect to shares held in street name, such banks and brokers have the discretion to vote on routine matters, but not on non-routine matters. The approval of the Extension Amendment Proposal is a non-routine matter, while the Adjournment Proposal, if presented, will be considered a routine matter.

For non-routine matters your broker can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares. Your broker can tell you how to provide these instructions. If you do not give your broker instructions, your shares will be treated as broker non-votes with respect to the Extension Amendment Proposal. Broker non-votes will have the same effect as a vote AGAINST the Extension Amendment Proposal; however, since the Adjournment Proposal is considered a routine matter, brokers shall be entitled to vote on the Adjournment Proposal absent voting instructions, and thus there should be no broker non-votes with respect to the Adjournment Proposal.

9

Q: What is a quorum requirement?

A: A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares of common stock on the Record Date entitled to vote, including those shares held as a constituent part of our units, are represented virtually or by proxy at the Special Meeting.

Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the presiding officer of the Special Meeting may adjourn the Special Meeting to another date.

As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor holds enough shares to constitute a quorum on its own.

Q: Who can vote at the Special Meeting?

A: Only holders of record of the Company’s common stock, including those shares held as a constituent part of our units, at the close of business on November 7, 2023, the Record Date, are entitled to have their vote counted at the Special Meeting and any adjournments or postponements thereof. On the Record Date, 8,834,645 shares were outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name. If on the Record Date your shares or units were registered directly in your name with the Company’s transfer agent, Continental Stock Transfer & Trust Company, then you are a stockholder of record. As a stockholder of record, you may vote virtually at the Special Meeting or vote by proxy. Whether or not you plan to attend the Special Meeting virtually, the Company urges you to fill out and return the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank. If on the Record Date your shares or units were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Special Meeting virtually. However, since you are not the stockholder of record, you may not vote your shares virtually at the Special Meeting unless you request and obtain a valid proxy from your broker or other agent.

Q: What interests do the Company’s directors and executive officers have in the approval of the proposals presented in this proxy statement?

A: The Company’s directors and executive officers have interests in the Extension Amendment Proposal that may be different from, or in addition to, your interests as a stockholder. These interests include ownership by them or their affiliates of founder shares, and warrants that may become exercisable in the future, loans by them that will not be repaid in the event of our winding up and the possibility of future compensatory arrangements. See the section entitled “The Extension Amendment Proposal — Interests of the Company’s Directors and Officers.”

Q: Do I have appraisal rights?

A: Stockholders do not have appraisal rights in connection with the Extension Amendment Proposal or, if presented, the Adjournment Proposal under the Delaware General Corporation Law (“DGCL”).

Q: What happens to the Company’s warrants if the Extension Amendment Proposal is not approved?

A: If the Extension Amendment Proposal is not approved and the Company has not consummated the Picard Business Combination by the Current Outside Date, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest

10

income earned on the trust account (which interest shall be net of taxes payable and after setting aside up to $100,000 to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no distribution from the trust account with respect to our warrants, which will expire worthless in the event the Company winds up.

Q: What happens to the Company warrants if the Extension Amendment Proposal is approved?

A: If the Extension Amendment Proposal is approved, the Company will file an amendment to the charter with the Secretary of State of the State of Delaware in the form of Annex A hereto. The warrants will remain outstanding in accordance with their terms.

Q: How do I redeem my public shares?

A: If the Extension is implemented, each public stockholder may seek to redeem all or a portion of his or her public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. You will also be able to redeem your public shares in connection with any stockholder vote to approve the Picard Business Combination, or if the Company has not consummated the Picard Business Combination by the Extended Date.

Pursuant to our charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Extension Amendment Proposal is approved and the Extension is implemented. You will be entitled to receive cash for any public shares to be redeemed only if you:

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 Extension Amendment Proposal and regardless of whether they hold public shares on the Record Date.

If you hold your shares through a bank or broker, you must ensure your bank or broker complies with the requirements identified herein, including submitting a written request that your shares be redeemed for cash to the transfer agent and delivering your shares to the transfer agent prior to 5:00 p.m. Eastern Time on December 4, 2023 (two business days before the scheduled vote at the Special Meeting). You will only be entitled to receive cash in connection with a redemption of these shares if you continue to hold them until the effective date of the Extension Amendment.

11

Through DTC’s DWAC (Deposit/Withdrawal at Custodian) System, this electronic delivery process can be accomplished by the stockholder, whether or not it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC, and the Company’s transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker a fee and the broker would determine whether or not to pass this cost on to the redeeming holder. It is the Company’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. The Company does not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical stock certificate. Such stockholders will have less time to make their investment decision than those stockholders that deliver their shares through the DWAC system. Stockholders who request physical stock certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to the vote on the Extension Amendment Proposal will not be redeemed for cash held in the trust account. In the event that a public stockholder tenders its shares and decides prior to the vote at the Special Meeting that it does not want to redeem its shares, the stockholder may withdraw the tender. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the Special Meeting not to redeem your public shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public stockholder tenders shares and the Extension Amendment Proposal is not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the stockholder promptly following the determination that the Extension Amendment Proposal will not be approved. The transfer agent will hold the certificates of public stockholders that make the election until such shares are redeemed for cash or returned to such stockholders.

Q: If I am a unit holder, can I exercise redemption rights with respect to my units?

A: No. Holders of outstanding units must separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares.

If you hold units registered in your own name, you must deliver the certificate for such units to Continental Stock Transfer & Trust Company, our transfer agent, with written instructions to separate such units into public shares, and public warrants. This must be completed far enough in advance to permit the mailing of the public share certificates back to you so that you may then exercise your redemption rights upon the separation of the public shares from the units. See “How do I redeem my public shares?” above.

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

A: You may receive more than one set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards, if your shares are registered in more than one name or are registered in different accounts. 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. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares of common stock.

Q: Who is paying for this proxy solicitation?

A: The Company will pay for the entire cost of soliciting proxies. The Company has engaged Morrow Sodali LLC (“Morrow Sodali”) to assist in the solicitation of proxies for the Special Meeting. The Company has agreed to pay Morrow Sodali a fee of $15,000. The Company will also reimburse Morrow Sodali for reasonable and

12

customary out-of-pocket expenses. In addition to these mailed proxy materials, our directors and executive officers may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. The Company may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

Q: Where do I find the voting results of the Special Meeting?

A: We will announce preliminary voting results at the Special Meeting. The final voting results will be tallied by the inspector of election and published in the Company’s Current Report on Form 8-K, which the Company is required to file with the SEC within four business days following the Special Meeting.

RISK FACTORS

You should consider carefully all of the risks described in our Annual Report on Form 10-K filed with the SEC on March 23, 2023, and in the other reports we file with the SEC before making a decision to invest in our securities. Risks specific to the Picard Business Combination can be found in the merger proxy filed with the SEC. Furthermore, if any of the following events occur, our business, financial condition and operating results may be materially adversely affected or we could face liquidation. In that event, the trading price of our 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 we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results or result in our liquidation.

There are no assurances that the Extension will enable us to complete the Picard Business Combination.

Approving the Extension involves a number of risks. Even if the Extension is approved and implemented, the Company can provide no assurances that the Picard Business Combination will be consummated prior to the Extended Date. Our ability to consummate the Picard Business Combination is dependent on a variety of factors, many of which are beyond our control. If the Extension is approved and implemented, the Company expects to seek stockholder approval of the Picard Business Combination. We are required to offer stockholders the opportunity to redeem shares in connection with the Extension Amendment, and we will be required to offer stockholders redemption rights again in connection with any stockholder vote to approve the Picard Business Combination. Even if the Extension or the Picard Business Combination are approved by our stockholders, it is possible that redemptions will leave us with insufficient cash or public float to consummate the Picard Business Combination on commercially acceptable terms, or at all. The fact that we will have separate redemption periods in connection with the Extension and the Picard Business Combination vote could exacerbate these risks. Other than in connection with a redemption offer or liquidation, our stockholders may be unable to recover their investment except through sales of our shares on the open market. The price of our shares may be volatile, and there can be no assurance that stockholders will be able to dispose of our shares at favorable prices, or at all.

The Extension contemplated by the Extension Amendment Proposal contravenes Nasdaq rules, and as a result, could lead Nasdaq to suspend trading in the Company’s securities or lead the Company to be delisted from Nasdaq.

The Company is listed on The Nasdaq Capital Market. Nasdaq IM-5101-2 requires that a special purpose acquisition company complete one or more business combinations within 36 months of the effectiveness of its IPO registration statement, which, in the case of the Company, would be December 8, 2023 (the “Nasdaq Deadline”). The Extension to the Extended Date contemplated by the Extension Amendment Proposal would extend the Company’s Current Outside Date beyond the Nasdaq Deadline. As a result, the Extension does not comply with Nasdaq rule IM-5101-2. There is a risk that trading in the Company’s securities may be suspended and the Company may be subject to delisting by Nasdaq if the Extension Amendment Proposal is approved and the Extension is implemented. We cannot assure you that Nasdaq will not delist the Company’s securities in the event the Extension Amendment Proposal is approved and the Extension is implemented and the Company does not complete one or more business combinations by the Nasdaq Deadline, that we will be able to obtain a hearing with Nasdaq’s Hearings Panel to appeal the delisting determination, or that our securities will not be suspended pending the Hearing Panel’s decision

If Nasdaq delists any of our securities from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect such securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

14

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because our units, common stock, and warrants are currently listed on Nasdaq, our units, common stock, and warrants are covered securities. Although the states are preempted from regulating the sale of our securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. While we are not aware of a state having used these powers to prohibit or restrict the sale of securities issued by blank check companies, other than the state of Idaho, certain state securities regulators view blank check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if we were no longer listed on Nasdaq, our securities would not be covered securities and we would be subject to regulation in each state in which we offer our securities.

The ability of our public stockholders to exercise redemption rights if the Extension Amendment Proposal is approved with respect to a large number of our public shares may adversely affect the liquidity of our securities.

Pursuant to our charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Extension Amendment Proposal is approved. The ability of our public stockholders to exercise such redemption rights with respect to a large number of our public shares may adversely affect the liquidity of our common stock. As a result, you may be unable to sell your common stock even if the per-share market price is higher than the per-share redemption price paid to public stockholders that elect to redeem their public shares if the Extension Amendment Proposal is approved.

A new 1% U.S. federal excise tax could be imposed on us in connection with redemptions by us of our shares.

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) became law, which, among other things, imposes a new U.S. federal 1% excise tax on certain repurchases (including certain redemptions) of stock by publicly traded domestic (i.e., U.S.) corporations and certain domestic subsidiaries of publicly traded foreign (i.e., non-U.S.) corporations (each, a “covered corporation”). The excise tax will apply to repurchases occurring in 2023 and beyond. Because we are a Delaware corporation and our securities are trading on Nasdaq, we are a “covered corporation” for this purpose. The excise tax is imposed on the repurchasing corporation itself, not its stockholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of Treasury has authority to provide regulations and other guidance to carry out, and prevent the abuse or avoidance of, the excise tax. On December 27, 2022, the U.S. Department of the Treasury issued a notice that provides interim operating rules for the excise tax, including rules governing the calculation and reporting of the excise tax, on which taxpayers may rely until the forthcoming proposed Treasury regulations addressing the excise tax are published. Although such notice clarifies certain aspects of the excise tax, the interpretation and operation of other aspects of the excise tax remain unclear, and such interim operating rules are subject to change.

Whether and to what extent we would be subject to the excise tax on a redemption of our stock would depend on a number of factors, including (i) whether the redemption is treated as a repurchase of stock for purposes of the

15

excise tax, (ii) the fair market value of the redemption treated as a repurchase of stock in connection with an initial business combination, (iii) the nature and amount of the equity issued, if any, by us (whether in connection with an initial business combination or otherwise) within the same taxable year of the redemption treated as a repurchase of stock, and (iv) the content of forthcoming regulations and other guidance from the U.S. Department of the Treasury. As noted above, the excise tax is imposed on the repurchasing corporation itself, not the stockholders from which shares are repurchased, and only limited guidance on the mechanics of any required reporting and payment of the excise tax on which taxpayers may rely have been issued to date. The imposition of the excise tax could reduce the amount of cash available on hand to complete an initial business combination or for effecting redemptions, and may affect our ability to complete an initial business combination.

If we are deemed to be an investment company for purposes of the Investment Company Act, we may be forced to abandon our efforts to complete an initial business combination and instead be required to liquidate the Company. To mitigate the risk of that result, on December 5, 2022, we instructed Continental Stock Transfer & Trust Company to liquidate the securities held in the trust account and instead hold all funds in the trust account in cash. As a result, following such change, we will likely receive minimal, if any, interest, on the funds held in the trust account, which would reduce the dollar amount that our public stockholders would have otherwise received upon any redemption or liquidation of the Company if the assets in the trust account had remained in U.S. government securities or money market funds.

On March 30, 2022, the SEC issued the SPAC Rule Proposals, relating, among other things, to a proposed safe harbor for SPACs from the definition of “investment company” under Section 3(a)(1)(A) of the Investment Company Act, provided that a SPAC satisfies certain criteria. To comply with the duration limitation of the proposed safe harbor, a SPAC would have a limited time period to announce and complete a de-SPAC transaction. Specifically, to comply with the safe harbor, the SPAC Rule Proposals would require a company to file a report on Form 8-K announcing that it has entered into an agreement with a target company for an initial business combination no later than 18 months after the effective date of the registration statement for its initial public offering. The company would then be required to complete its initial business combination no later than 24 months after the effective date of the registration statement for its initial public offering. We understand that the SEC has recently been taking informal positions regarding the Investment Company Act consistent with the SPAC Rule Proposals.

There is currently uncertainty concerning the applicability of the Investment Company Act to a SPAC, including a company like ours, that does not complete its initial business combination within the proposed time frame set forth in the proposed safe harbor rule. As indicated above, we completed our IPO in December 2020 and have operated as a blank check company searching for a target business with which to consummate an initial business combination since such time. As a result, it is possible that a claim could be made that we have been operating as an unregistered investment company if the SPAC Rule Proposals are adopted as proposed. If we were deemed to be an investment company for purposes of the Investment Company Act, we might be forced to abandon our efforts to complete an initial business combination and instead be required to liquidate the Company. If we are required to liquidate the Company, our investors would not be able to realize the benefits of owning shares in a successor operating business, including the potential appreciation in the value of our shares and warrants or rights following such a transaction, and our warrants or rights would expire worthless.

To mitigate the risk of us being deemed to have been operating as an unregistered investment company under the Investment Company Act, on December 5, 2022, we instructed Continental Stock Transfer and Trust Company, the trustee with respect to the trust account, to liquidate the U.S. government treasury obligations or money market funds held in the trust account and thereafter to hold all funds in the trust account in an interest-bearing bank deposit account until the earlier of the consummation of a business combination or our liquidation. Following such liquidation of the assets in our trust account, we will likely receive minimal interest, if any, on the funds held in the trust account, which would reduce the dollar amount our public stockholders would have otherwise received upon any redemption or liquidation of the Company if the assets in the trust account had remained in U.S. government securities or money market funds. This means that the amount available for redemption will not increase in the future.

THE SPECIAL MEETING

Date, Time, Place and Purpose of the Special Meeting

The Special Meeting will be held at 10 a.m. Eastern Time, on December 6, 2023. The Special Meeting will be held virtually, at https://www.cstproxy.com/altitudeac/sm2023. At the Special Meeting, the stockholders will consider and vote upon the following proposals.

Voting Power; Record Date

You will be entitled to vote or direct votes to be cast at the Special Meeting if you owned our common stock, including as a constituent part of a unit, at the close of business on November 7, 2023, the Record Date for the Special Meeting. You will have one vote per share for each share of common stock you owned at that time. Our warrants do not carry voting rights.

At the close of business on the Record Date, there were 8,834,645 outstanding shares of common stock, each of which entitles its holder to cast one vote per share.

Votes Required

The affirmative vote of 65% of the outstanding common stock will be required to approve the Extension Amendment Proposal Approval. Approval of the Adjournment Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person (including virtually) or by proxy at the Special Meeting.

As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal and Adjournment Proposal even if no other shares are voted in favor of such proposals.

If you do not vote (i.e., you “abstain” from voting), your action will have the same effect as an “AGAINST” vote with regards to the Extension Amendment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome of the Adjournment Proposal. Broker non-votes will have the same effect as “AGAINST” votes with respect to the Extension Amendment Proposal. If you do not want the Extension Amendment Proposal to be approved, you must abstain, not vote, or vote against the proposal. Since the Adjournment Proposal is considered a routine matter, brokers shall be entitled to vote on the Adjournment Proposal absent voting instructions, and thus there should be no broker non-votes with respect to the Adjournment Proposal.

Voting

If you are a record owner of your shares, there are two ways to vote your shares at the Special Meeting: you can vote your shares at the Special Meeting by proxy or virtually.

If you are a record holder and wish to vote by proxy, you must (i) complete the enclosed form, called a “proxy card,” and mail it in the envelope provided or (ii) submit your proxy by telephone or over the Internet (if those

17

options are available to you) in accordance with the instructions on the enclosed proxy card or voting instruction card.

If you complete the proxy card and mail it in the envelope provided or submit your proxy by telephone or over the Internet as described above, you will designate Gary Teplis and Warren Hosseinion to act as your proxy at the Special Meeting. One of them will then vote your shares at the Special Meeting in accordance with the instructions you have given them in the proxy card or voting instructions, as applicable, with respect to the proposals presented in this proxy statement. Proxies will extend to, and be voted at, any adjournment(s) of the Special Meeting.

Alternatively, you can vote your shares in person by attending the Special Meeting virtually.

A special note for those who plan to attend the Special Meeting and vote virtually: if your shares or units are held in the name of a broker, bank or other nominee, please follow the instructions you receive from your broker, bank or other nominee holding your shares. You will not be able to vote at the Special Meeting unless you obtain a legal proxy from the record holder of your shares.

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. If you wish to attend the Special Meeting and vote in person or online and your shares are held in “street name,” you must obtain a legal proxy from your broker, bank or nominee. That is the only way the Company can be sure that the broker, bank or nominee has not already voted your shares.

Our Board is asking for your proxy. Giving our Board your proxy means you authorize it to vote your shares at the Special Meeting in the manner you direct. You may vote for or against any proposal or you may abstain from voting. All valid proxies received prior to the Special Meeting will be voted. All shares represented by a proxy will be voted, and where a stockholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the specification so made. If no choice is indicated on the proxy, the shares will be voted “FOR” each of the proposals set forth in this proxy statement, and as the proxy holders may determine in their discretion with respect to any other matters that may properly come before the Special Meeting.

Stockholders who have questions or need assistance in completing or submitting their proxy cards should contact our proxy solicitor, Morrow Sodali, at (203) 658-9400 (call collect), (800) 662-5200 (call toll-free), or by sending an email to ALTU.info@investor.morrowsodali.com.

Stockholders who hold their shares in “street name,” meaning the name of a broker or other nominee who is the record holder, must either direct the record holder of their shares to vote their shares or obtain a legal proxy from the record holder to vote their shares at the Special Meeting.

Revocability of Proxies

Any proxy may be revoked by the person giving it at any time before the polls close at the Special Meeting. A proxy may be revoked by filing with Gary Teplis, President and Chief Executive Officer, at Altitude Acquisition Corp., 400 Perimeter Center Terrace, Suite 151 Atlanta, Georgia 30346, either a written notice of revocation bearing a date later than the date of such proxy or a subsequent proxy relating to the same shares or by attending the Special Meeting and voting virtually.

Simply attending the Special Meeting will not constitute a revocation of your proxy. If your shares are held in the name of a broker or other nominee who is the record holder, you must follow the instructions of your broker or other nominee to revoke a previously given proxy.

18

Attendance at the Special Meeting

Only holders of common stock, their proxy holders and guests the Company may invite may attend the Special Meeting. If you wish to attend the Special Meeting virtually but you hold your shares or units through someone else, such as a broker, please follow the instructions you receive from your broker, bank or other nominee holding your shares. You must bring a legal proxy from the broker, bank or other nominee holding your shares, confirming your beneficial ownership of the shares and giving you the right to vote your shares.

Solicitation of Proxies

Your proxy is being solicited by our Board on the proposals being presented to the stockholders at the Special Meeting. The Company has agreed to pay Morrow Sodali a fee of $15,000. The Company will also reimburse Morrow Sodali for reasonable and customary out-of-pocket expenses. In addition to these mailed proxy materials, our directors and executive officers may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. The Company may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. You may contact Morrow Sodali at:

Email: ALTU.info@investor.morrowsodali.com

The cost of preparing, assembling, printing and mailing this proxy statement and the accompanying form of proxy, and the cost of soliciting proxies relating to the Special Meeting, will be borne by the Company. Some banks and brokers have customers who beneficially own common stock listed of record in the names of nominees. The Company intends to request banks and brokers to solicit such customers and will reimburse them for their reasonable out-of-pocket expenses for such solicitations. If any additional solicitation of the holders of our outstanding common stock is deemed necessary, the Company (through our directors and executive officers) anticipates making such solicitation directly.

No Right of Appraisal

The Company’s stockholders do not have appraisal rights under the DGCL in connection with the proposals to be voted on at the Special Meeting. Accordingly, our stockholders have no right to dissent and obtain payment for their shares.

Other Business

The Company is not currently aware of any business to be acted upon at the Special Meeting other than the matters discussed in this proxy statement. The form of proxy accompanying this proxy statement confers discretionary authority upon the named proxy holders with respect to amendments or variations to the matters identified in the accompanying Notice of Special Meeting and with respect to any other matters which may properly come before the Special Meeting. If other matters do properly come before the Special Meeting, or at any adjournment(s) of the Special Meeting, the Company expects that the shares of common stock represented by properly submitted proxies will be voted by the proxy holders in accordance with the recommendations of our Board.

PROPOSAL NO. 1 — THE EXTENSION AMENDMENT PROPOSAL

Background

We are a blank check company whose business purpose is to effect a merger, capital stock exchange, asset acquisition, stock purchase reorganization or similar business combination with one or more businesses. We were incorporated in Delaware on August 12, 2020. In connection with our formation, we issued an aggregate of 7,500,000 founder shares to our Sponsor for an aggregate purchase price of $25,000.

On December 11, 2020, we consummated our IPO of 30,000,000 units, including 3,900,000 units issued to the underwriters based on a partial exercise of their over-allotment option. Each unit consists of one share of Class A common stock and one-half of one redeemable public warrant, with each whole warrant entitling the holder thereof to purchase one share of Class A common stock for $11.50 per share. The units were sold at a price of $10.00 per unit, generating gross proceeds of $300,000,000.

Simultaneously with the consummation of the IPO, we completed the private sale of an aggregate of 8,000,000 private placement warrants to our Sponsor at a purchase price of $1.00 per warrant, generating gross proceeds of $8,000,000.

The prospectus for our IPO and our charter originally provided that we had until June 11, 2022, or 18 months after the closing of our IPO, to complete a business combination. We were not able to consummate an initial business combination by such date and on June 10, 2022, our stockholders approved an amendment to the charter to provide that we would have until October 11, 2022. In connection with this amendment, the Company offered public stockholders the right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 24,944,949 public shares exercised their right to redeem their shares at a redemption price of approximately $10.01 per share, or a total of $249,614,847 of the funds held in the Company’s trust account.

The Company was also unable to complete a qualifying business combination by October 11, 2022 and on October 6, 2022 the Company’s stockholders approved an amendment to the charter to provide that the Company would have until April 11, 2023 to complete a business combination. In connection with such amendment, the Company offered public stockholders the right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 3,382,949 public shares exercised their right to redeem their shares at a redemption price of approximately $10.05 per share, or a total of $34,009,688.61 of the funds held in the Company’s trust account.

The Company was also unable to complete a business combination by April 11, 2023 and on April 7, 2023, the Company’s stockholders approved an amendment to the charter to provide that the Company would have until May 11, 2023 to complete a business combination which could be extended the monthly until December 11, 2023. In connection with such amendment, the Company offered public stockholders right to have their public shares redeemed for a pro rata portion of the trust account and stockholders holding an aggregate of 337,457 public shares exercised their right to redeem their shares for approximately $10.08 per share, or a total of $3,401,567 of the funds held in the Company’s trust account.

On December 5, 2022, to mitigate the risk of being viewed as operating as an unregistered investment company, we instructed Continental Trust Stock Transfer and Trust Company, the trustee with respect to the trust account, to liquidate the U.S. government treasury obligations or money market funds held in the trust account and thereafter to hold all funds in the trust account in an interest-bearing bank deposit account.

As of the Record Date, the Company has approximately $13,798,537 of cash in the trust account.

The Extension Amendment

The Company is proposing to amend its charter to extend the date by which the Company must consummate a business combination. The Extension Amendment would allow us, without another stockholder vote, to elect to

20

extend the Extended Date on a monthly basis 3 additional times until March 11, 2024, or a total of up to 3 months after the Current Outside Date by resolution of the Board.

The Company entered into the Picard Business Combination Agreement on April 23, 2023, and is using its best efforts to complete the Picard Business Combination as soon as practicable. The Company has filed a merger proxy with the SEC but has not cleared all SEC comments and believes that it will not have enough time to satisfy all closing conditions and complete all actions required to consummate the Picard Business Combination before the Current Outside Date. The purpose of the Extension Amendment Proposal is therefore to provide sufficient time to complete the Picard Business Combination.

A copy of the proposed amendment to the Company’s charter is attached to this proxy statement as Annex A.

Reasons for the Proposal

The charter provides that the Company has until the Current Outside Date to complete a business combination. The purpose of the Extension Amendment Proposal is to provide the Company with sufficient time to complete the Picard Business Combination. The Company believes that given the Company’s expenditure of time, effort and money in seeking to consummate the Picard Business Combination, circumstances warrant providing public stockholders an opportunity to consider the Picard Business Combination. Accordingly, since the Company believes it will not be able to complete the Picard Business Combination by the Current Outside Date, the Company has determined to seek stockholder approval to extend the time for closing the Picard Business Combination beyond the Current Outside Date to the Extended Date.

If the Extension Amendment Proposal is Not Approved

Stockholder approval of the Extension Amendment Proposal is required for the implementation of our Board’s plan to extend the date by which we must consummate the Picard Business Combination. Therefore, our Board will abandon and not implement the Extension Amendment unless our stockholders approve the Extension Amendment Proposal.

If the Extension Amendment Proposal is not approved and the Company does not consummate the Picard Business Combination by the Current Outside Date, in accordance with our charter, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable and after setting aside up to $100,000 to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The initial stockholders have waived their rights to participate in any liquidation distribution with respect to such shares. There will be no distribution from the trust account with respect to the Company’s warrants, which will expire worthless in the event the Company does not consummate the Picard Business Combination by the Current Outside Date if the Extension Amendment Proposal is not approved. The Company will pay the costs of liquidation from its remaining assets outside of the trust account. If such funds are insufficient, our Sponsor has agreed to advance it the funds necessary to complete such liquidation and has agreed not to seek repayment of such expenses.

21

If the Extension Amendment Proposal is Approved

If the Extension Amendment Proposal is approved, the Company will file an amendment to the charter with the Secretary of State of the State of Delaware to extend the time it has to complete the Picard Business Combination. The Company will then continue to work to consummate the Picard Business Combination.

You are not being asked to vote on the Picard Business Combination at this time. If the Extension is implemented and you do not elect to redeem your public shares in connection with the Extension, you will retain the right to vote on the Picard Business Combination when it is submitted to the public stockholders (provided that you are a stockholder on the record date for a meeting to consider the Picard Business Combination) and the right to redeem your public shares for a pro rata portion of the trust account in the event the Picard Business Combination is approved and completed or the Company has not consummated the Picard Business Combination by the Extended Date.

If the Extension Amendment Proposal is approved and the Extension is implemented, the removal of the Withdrawal Amount from the trust account will reduce the amount held in the trust account. The Company cannot predict the amount that will remain in the trust account after such withdrawal if the Extension Amendment Proposal is approved and the amount remaining in the trust account may be only a fraction of the $13,798,537 (including interest but less the funds used to pay taxes) that was in the trust account as of the Record Date. In such event, the Company may still seek to obtain additional funds to complete the Picard Business Combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

The Company is listed on The Nasdaq Capital Market. Nasdaq rule IM-5101-2 requires that a special purpose acquisition company complete one or more business combinations within 36 months of the effectiveness of its IPO registration statement, which, in the case of the Company, would be December 8, 2023. The Extension to the Extended Date would extend the Company’s life beyond such 36-month deadline. As a result, the contemplated Extension does not comply with Nasdaq rules. We may be subject to suspension or delisting by Nasdaq if the Extension Amendment Proposal is approved and the Extension is implemented. For more information see “Risk Factors – The Extension contemplated by the Extension Amendment Proposal contravenes Nasdaq rules, and as a result, could lead Nasdaq to suspend trading in the Company’s securities or lead the Company to be delisted from Nasdaq.

Redemption Rights

If the Extension Amendment Proposal is approved, and the Extension is implemented, public stockholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. If the Extension Amendment Proposal is approved by the requisite vote of stockholders, the remaining holders of public shares will retain the opportunity to have their public shares redeemed in conjunction with the consummation of the Picard Business Combination, subject to any limitations set forth in our charter, as amended. In addition, public stockholders who do not elect to redeem would be entitled to have their shares redeemed for cash if the Company has not completed the Picard Business Combination by the Extended Date.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST ENSURE YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED HEREIN, INCLUDING SUBMITTING A WRITTEN REQUEST THAT YOUR SHARES BE REDEEMED FOR CASH TO THE TRANSFER AGENT AND DELIVERING YOUR SHARES TO THE TRANSFER AGENT PRIOR TO 5:00 P.M. EASTERN TIME ON DECEMBER 4, 2023 (TWO BUSINESS DAYS BEFORE THE SCHEDULED VOTE AT THE SPECIAL MEETING). YOU WILL ONLY BE ENTITLED TO RECEIVE CASH IN CONNECTION WITH A REDEMPTION OF THESE SHARES IF YOU CONTINUE TO HOLD THEM UNTIL THE EFFECTIVE DATE OF THE EXTENSION AMENDMENT.

22

Pursuant to our charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Extension Amendment Proposal is approved and the Extension is implemented. You will be entitled to receive cash for any public shares to be redeemed only if you:

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 Extension Amendment Proposal and regardless of whether they hold public shares on the Record Date.

Through DTC’s DWAC (Deposit/Withdrawal at Custodian) System, this electronic delivery process can be accomplished by the stockholder, whether or not it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC, and the Company’s transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker a fee and the broker would determine whether or not to pass this cost on to the redeeming holder. It is the Company’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. The Company does not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical stock certificate. Such stockholders will have less time to make their investment decision than those stockholders that deliver their shares through the DWAC system. Stockholders who request physical stock certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares. Certificates that have not been tendered in accordance with these procedures prior to the vote on the Extension Amendment will not be redeemed for cash held in the trust account on the redemption date. In the event that a public stockholder tenders its shares and decides prior to the vote at the Special Meeting that it does not want to redeem its shares, the stockholder may withdraw the tender. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the Special Meeting not to redeem your public shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public stockholder tenders shares and the Extension Amendment Proposal is not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the stockholder promptly following the determination that the Extension Amendment will not be approved. The transfer agent will hold the certificates of public stockholders that make the election until such shares are redeemed for cash or returned to such stockholders.

If properly demanded, the Company will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the funds held in the

23

trust account and not previously released to us to pay our franchise and income taxes, divided by the number of then outstanding public shares. Based on the amount in the trust account as of the Record Date, this would amount to approximately $10.34 per share. The closing price of the common stock on Nasdaq on November 7, 2023, the Record Date, was $10.15. Accordingly, if the market price were to remain the same until the date of the Special Meeting, exercising redemption rights would result in a public stockholder receiving approximately $0.19 more than if such stockholder sold the public shares in the open market. The Company cannot assure public stockholders that they will be able to sell their public shares 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 securities when such stockholders wish to sell their shares.

If you exercise your redemption rights, you will be exchanging your shares of the Company’s common stock for cash and will no longer own the shares. You will be entitled to receive cash for these shares only if you properly demand redemption and tender your stock certificate(s) to the Company’s transfer agent prior to 5:00 p.m. Eastern Time on December 4, 2023 (two business days before the scheduled vote at the Special Meeting).

Interests of the Company’s Directors and Executive Officers

When you consider the recommendation of our Board, you should keep in mind that the Company’s executive officers and directors, and their affiliates, have interests that may be different from, or in addition to, your interests as a stockholder. These interests include, among other things:

24

Additionally, our Sponsor, officers and directors have additional interests in the Picard Business Combination, which are described in the merger proxy filed in connection with the Picard Business Combination.

U.S. Federal Income Tax Considerations

The following discussion is a summary of certain U.S. federal income tax considerations for U.S. Holders and Non-U.S. Holders (each as defined below, and together, “Holders”) of public shares (i) of the Extension Amendment Proposal, and (ii) that elect to have their public shares redeemed for cash if the Extension Amendment Proposal is approved. This section applies only to Holders that hold their public shares 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 also should apply to holders of units (as the deemed owners of the underlying public shares and public warrants that constitute the units). Accordingly, the separation of units into the public shares and public warrants underlying the units 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 U.S. Internal Revenue Service (“IRS”) would not assert, or that a court would not sustain, a contrary position. Holders of units are urged to consult their tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of the transactions contemplated by the Extension Amendment (including any redemption of the public shares in connection therewith if the Extension Amendment Proposal is approved) with respect to any public shares held through the units (including alternative characterizations of the units).

This discussion does not address the U.S. federal income tax consequences to our Sponsor or its affiliates, officers or directors, or to any person of holding founder shares or private placement warrants. This discussion is limited to U.S. federal income tax considerations and does not address any estate or gift 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:

25

If a partnership (or any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds public shares, 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 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 Extension Amendment Proposal and the exercise of their redemption rights with respect to their public shares in connection therewith.

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 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 U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE EXTENSION AMENDMENT PROPOSAL AND THE EXERCISE OF REDEMPTION RIGHTS IN CONNECTION THEREWITH. EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE EXTENSION AMENDMENT PROPOSAL AND THE EXERCISE OF REDEMPTION RIGHTS, INCLUDING THE APPLICABILITY AND EFFECTS OF U.S. FEDERAL NON-INCOME, STATE AND LOCAL AND NON-U.S. TAX LAWS.

Tax Treatment of Non-Redeeming Stockholders

A public stockholder who does not elect to redeem their public shares (including any public stockholder who votes in favor of the Extension Amendment) will continue to own its public shares, and will not recognize any

26

income, gain or loss for U.S. federal income tax purposes solely as a result of the Extension Amendment Proposal.

Tax Treatment of Redeeming Stockholders

U.S. Holders

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

Generally

The U.S. federal income tax consequences to a U.S. Holder of public shares that exercises its redemption rights with respect to its public shares to receive cash in exchange for all or a portion of its public shares will depend on whether the redemption qualifies as a sale of public shares under Section 302 of the Code. If the 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 Treated as a Sale of Public Shares.” If the 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 Treated as a Distribution.”

Whether a redemption of public shares qualifies for sale treatment 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 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 redemption. The redemption of public shares generally will be treated as a sale of public shares (rather than as a corporate distribution) if the redemption (1) is “substantially disproportionate” with respect to the U.S. Holder, (2) results in a “complete termination” 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 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 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 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

27

redemption (taking into account redemptions by other holders of public shares). There will be a complete termination 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 redemption of public shares will not be essentially equivalent to a dividend if the redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in the Company. Whether the 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 the 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 Treated as a 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.

Taxation of Redemption Treated as a 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 “—Generally,” 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.

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 Treated as a Sale of Public Shares.”

Taxation of Redemption 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 “—Generally,” 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.

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 redemption of public shares, and such holders should consult with their tax advisors with respect to their reporting requirements.

28

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.

Information Reporting and Backup Withholding

Payments of cash to a U.S. Holder as a result of the redemption of public shares may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and the U.S. Holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Non-U.S. Holders

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

Generally

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 qualifies as a sale of the public shares redeemed, as described above under “Tax Treatment of Redeeming Stockholders—U.S. Holders—Generally.” If such a redemption qualifies 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 Treated as a Sale of Public Shares.” If such a redemption does not qualify 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 as a 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 will 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 “Tax Treatment of Redeeming Stockholders—U.S. Holders—Generally”). 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.

29

Taxation of Redemption as a 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 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 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 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 “—Generally,” unless:

30

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.

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with payments of dividends on, and the proceeds from a sale of, public shares. A Non-U.S. Holder may have to comply with certification procedures to establish that it is not a U.S. person in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced rate of withholding under a treaty generally will satisfy the certification requirements necessary to avoid the backup withholding as well.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder generally will be allowed as a credit against such Non-U.S. Holder’s U.S. federal income tax liability and may entitle such Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Provisions commonly referred to as “FATCA” impose withholding 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

31

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.

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 Extension Amendment Proposal and the exercise of redemption rights in connection therewith.

Required Vote

The affirmative vote by holders of 65% of the Company’s outstanding common stock is required to approve the Extension Amendment. As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock. Accordingly, the Sponsor will be able to approve the Extension Amendment Proposal and Adjournment Proposal even if no other shares are voted in favor of such proposals.

All of the Company’s directors, executive officers and their affiliates are expected to vote any common stock owned by them in favor of the Extension Amendment.

In addition, the Sponsor or the Company’s officers, directors, advisors, or any of their respective affiliates, may purchase public shares in privately negotiated transactions or in the open market prior to or following the Special Meeting, although they are under no obligation to do so. Such public shares purchased by the Sponsor or its affiliates would be (a) purchased at a price no higher than the redemption price for the public shares, which is currently estimated to be $10.34 per share and (b) would not be (i) voted by such persons at the Special Meeting or (ii) redeemable by them. Any such purchases that are completed after the Record Date for the Special Meeting may include an agreement with a selling stockholder that such stockholder, for so long as it remains the record holder of the shares in question, will vote in favor of the proposals described in this proxy statement and/or will not exercise its redemption rights with respect to the shares so purchased. The purpose of such share purchases and other transactions would be to reduce the number of public shares that are redeemed. In the event that such purchases do occur, the purchasers may seek to purchase shares from stockholders who would otherwise have elected to redeem their shares for a portion of the trust account. Any such privately negotiated purchases may be effected at purchase prices that no higher than the per-share pro rata portion of the trust account. None of the initial stockholders, advisors or their respective affiliates may make any such purchases when they are in possession of any material non-public information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act.

Recommendation

As discussed above, after careful consideration of all relevant factors, our Board has determined that the Extension Amendment Proposal is in the best interests of the Company and its stockholders. Our Board has approved and declared advisable adoption of the Extension Amendment Proposal.

32

OUR BOARD RECOMMENDS THAT YOU VOTE “FOR” THE EXTENSION AMENDMENT PROPOSAL. OUR BOARD EXPRESSES NO OPINION AS TO WHETHER YOU SHOULD REDEEM YOUR PUBLIC SHARES.

The existence of financial and personal interests of our directors and officers may result in a conflict of interest on the part of one or more of the directors or officers between what he, she or they may believe is in the best interests of the Company and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the proposals. See the section entitled “The Extension Amendment Proposal—Interests of the Company’s Directors and Officers” for a further discussion.

33

PROPOSAL NO. 2—THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal, if adopted, will allow our Board to adjourn the Special Meeting to a later date or dates or indefinitely, if necessary or convenient, if we determine that additional time is necessary to effectuate the Extension.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by our stockholders, our Board may not be able to adjourn the Special Meeting to a later date or dates or indefinitely, if necessary or convenient.

Required Vote

The approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast by the Company’s stockholders represented in person (including virtually) or by proxy. Accordingly, if a valid quorum is otherwise established, a stockholder’s failure to vote by proxy or online at the Special Meeting will have no effect on the outcome of any vote on the Adjournment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome of the Adjournment Proposal. As of the date of this proxy statement, the Sponsor holds approximately 85% of the Company’s outstanding common stock and will be able to approve the Adjournment Proposal even if no public shares are voted in favor of such proposal.

Recommendation

As discussed above, after careful consideration of all relevant factors, our Board has determined that the Adjournment Proposal is in the best interests of the Company and its stockholders. Our Board has approved and declared advisable the adoption of the Adjournment Proposal.

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

The existence of financial and personal interests of our directors and officers may result in a conflict of interest on the part of one or more of the directors or officers between what he, she or they may believe is in the best interests of the Company and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the proposals. See the section entitled “The Extension Amendment Proposal—Interests of the Company’s Directors and Officers” for a further discussion.

PRINCIPAL STOCKHOLDERS

The following table sets forth information regarding the beneficial ownership of our common stock as of November 7, 2023, the Record Date of the Special Meeting, by:

Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all shares of common stock beneficially owned by them. The following table does not reflect record or beneficial ownership of the public warrants or private placement warrants as these warrants are not exercisable within 60 days of the date of this proxy statement.

The beneficial ownership of our common stock is based on 8,834,645 shares of common stock issued and outstanding as of November 7, 2023.

STOCKHOLDER PROPOSALS

If the Extension is implemented, the Company intends to hold a special meeting of stockholders for the purpose of approving the Picard Business Combination and related transactions. The Company’s next Annual Meeting of stockholders would be held at a future date to be determined by the post business-combination company. The Company expects that it would notify shareholders of the deadline for submitting a proposal for inclusion in the

35

proxy statement for its next Annual Meeting following the completion of the Picard Business Combination. You should direct any proposals to the Company’s secretary at the Company’s principal office. If you are a shareholder and you want to nominate a person for election to our Board or present a matter of business to be considered, under the charter you must give timely notice of the nomination or the matter, in writing, to the Company’s secretary. To be timely, the notice has to be given by November 23, 2023.

If the Extension is not implemented, and the Company does not consummate the Picard Business Combination by December 11, 2023, then the Company will cease all operations except for the purpose of winding up and there will be no further annual or special meetings.

DISCRETIONARY VOTING OF PROXIES

Pursuant to Rule 14a-4 promulgated by the SEC, stockholders are advised that our management will be permitted to exercise discretionary voting authority under proxies it solicits and obtains for the Special Meeting with respect to any proposal presented by a stockholder at the meeting, without any discussion of the proposal in our proxy statement for the meeting, unless we received notice of such proposal at our principal office prior to November 30, 2023.

OTHER MATTERS

Our Board knows of no matter that will be presented for consideration at the Special Meeting other than the matters referred to in this proxy statement.

Holders of shares of Common Stock included as part of the units sold in the Offering (the ”Offering Shares“) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are the Sponsor or officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as ”Public Stockholders“. In the event that the Corporation has not consummated an initial Business Combination by the completion window, the Board may, without another stockholder vote, elect to extend the period of time to consummate a Business Combination on a monthly basis for up to 3) times by an additional one month each time, by resolution of the Board, until March 11, 2024.”
