Item 1.01. Entry into a Material Definitive Agreement.

Termination of Business Combination Agreement with Picard

As previously disclosed, on April 23, 2023, Altitude Acquisition Corp., a Delaware corporation (the “Company”), entered into a business combination agreement (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 the Company, Altitude Merger Sub II, LLC a Delaware limited liability company and a direct wholly owned subsidiary of the Company, Picard Medical, Inc., a Delaware corporation (“Picard”) and Hunniwell Picard I, LLC, solely in its capacity as the representative, agent and attorney-in-fact of the securityholders of Picard.

On February 23, 2024, pursuant to Section 10.1(c) of the Picard Business Combination Agreement, the parties to the Picard Business Combination Agreement entered into a Mutual Termination and Release Agreement (the “Termination Agreement”) to terminate the Picard Business Combination Agreement (the “Termination”). The Termination Agreement also provides that each other agreement among the parties relating to the Picard Business Combination Agreement is automatically terminated concurrently with the Termination, including, and without limitation, the support agreement entered into by Picard, the Company and the Company’s sponsor (the “Sponsor Support Agreement”) and the support agreement entered into by Picard, the Company and certain Picard stockholders (the “Picard Support Agreement”). The Termination Agreement also provides for a mutual release of claims among the parties and their affiliates, except for claims of fraud and willful breach. No party will be required to pay a termination fee as a result of the mutual decision to enter into the Termination Agreement.

The foregoing description of the Termination Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the Termination Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K (this “Current Report”) and is incorporated herein by reference.

Entry into Business Combination Agreement with Vesicor

On February 29, 2024, the Company entered into a business combination agreement (the “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”), and Vesicor Therapeutics, Inc. a California corporation (“Vesicor”). The Business Combination Agreement provides, among other things, that on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Vesicor (the “Merger”), with Vesicor surviving as a wholly-owned subsidiary of the Company (the “Surviving Corporation”). Upon the closing of the Merger (the “Closing”), it is anticipated that the Company will change its name to “Vesicor Therapeutics, Inc.” and is referred to herein as “New Vesicor” as of the time following such change of name. The date on which the Closing actually occurs is hereinafter referred to as the “Closing Date.”

Vesicor is an early-stage biopharmaceutical company focused on the development of microvesicle-based therapeutics.

The Closing is expected to occur following the receipt of required approval by the stockholders of the Company and Vesicor, required regulatory approvals, the effectiveness of the registration statement on Form S-4 (“Registration Statement”) to be filed with the U.S. Securities and Exchange Commission (“SEC”) in connection with the Merger and the fulfilment of other conditions set forth in the Business Combination Agreement.

Consideration and Structure

Each share of common stock of the Vesicor, par value $0.001 per share (“Vesicor Common Stock”) held by a Vesicor securityholder immediately prior to the Effective Time (not including dissenting shares) shall be automatically cancelled and converted into the right to receive a pro rata portion of a number of shares of common stock of New Vesicor, par value $0.001 per share (“New Vesicor Common Stock”) equal to (i)(a) $70,000,000 plus (b) Closing Cash (as defined in the Business Combination Agreement) minus (c) Closing Indebtedness (as defined in the Business Combination Agreement), (ii) divided by $10.00. Each of Vesicor’s warrants that are outstanding and unexercised prior to the Merger, whether or not then exercisable, will be assumed by New Vesicor and will be converted into a warrant to acquire shares of New Vesicor Common Stock and will be subject to the same terms and conditions that applied to the Vesicor warrant immediately prior to the Merger.

Representations, Warranties and Covenants

The parties to the Business Combination Agreement have agreed to customary representations and warranties for transactions of this type. In addition, the parties to the Business Combination Agreement agreed to be bound by certain customary covenants for transactions of this type, including, among others, covenants with respect to the conduct of Vesicor, the Company and their respective subsidiaries during the period between execution of the Business Combination Agreement and the Closing. The representations, warranties and covenants of the parties made under the Business Combination Agreement will not survive the Closing. Each of the parties to the Business Combination Agreement has agreed to use its reasonable best efforts to cause all actions and things necessary to consummate and expeditiously implement the Merger.

Pursuant to the Merger Agreement, Vesicor and the Company will use commercially reasonable efforts to identify additional sources of financing for and negotiate the underlying subscription, financing and similar agreements in connection with the Closing (the “Closing Offering”). The Company will also use its best efforts to obtain stockholder approval to amend its certificate of incorporation to extend the time period for which the Company has to complete an initial business combination to a date mutually agreed between the Company and Altitude.

Conditions to Closing

Under the Business Combination Agreement, the obligations of the parties to consummate the Merger are subject to the satisfaction or waiver of certain customary closing conditions of the respective parties, including, without limitation: (i) the approval and adoption of the Business Combination Agreement and transactions contemplated thereby by requisite vote of the Company’s stockholders (the “Company Stockholder Approval”) and Vesicor’s stockholders (the “Vesicor Stockholder Approval”); (ii) the receipt of consents or approvals from the applicable governmental, regulatory or administrative authorities and each applicable waiting period or consent or approval under the HSR Act shall have expired, been terminated or obtained; (iii) there has not been any legal action, suit, claim or similar hearing or proceeding brought by any governmental body, agency, authority, court, arbitrator, or any public, private or industry regulatory authority, whether international, national, foreign, Federal, state, or local. to enjoin or otherwise restrict the consummation of the transactions; (iv) Vesicor shall have performed or complied with, in all material respects, all of its obligations required to be performed or complied with at or prior to the Closing Date; (v) the Company shall have performed or complied with, in all material respects, all of its obligations required to be performed or complied with at or prior to the Closing Date; (vi) the accuracy of the representations and warranties, and the performance of the covenants and agreements, of the Company, Merger Sub and Vesicor, respectively, subject to customary materiality qualifications; (vii) the absence of a material adverse effect with respect to Vesicor; (viii) the Company’s initial listing application with the Nasdaq Stock Market, LLC, NYSE American or another agreed-upon national securities exchange (the “Stock Exchange”) in connection with the Merger has been conditionally approved and, immediately following the Effective Time, the Company has satisfied any applicable initial and continuing listing requirements of the Stock Exchange, and the New Vesicor Common Stock has been approved for listing on the Stock Exchange; (x) the execution of the Registration Rights Agreement and the Lock-Up Agreement; (xi) the Company’s satisfactory completion of its due diligence investigation of Vesicor; (xii) both parties’ delivery of disclosure schedules within 30 days of the execution date of the Agreement; and (xiii) the parties obtaining sufficient financing prior to the Closing to pay transaction expenses and meet Altitude’s other obligations.

Termination

The Business Combination Agreement may be terminated under certain circumstances at any time prior to the Closing, including, without limitation: (i) by the Company or Vesicor, if the Closing has not occurred by October 1, 2024, which date shall be automatically extended to December 11, 2024 if the SEC has not declared the Registration Statement effective on or prior to October 1, 2024, but only if the party seeking to terminate is not in material breach; (ii) by the Company or Vesicor, in the event an applicable governmental, regulatory or administrative authority has issued a final and non-appealable order having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger; (iii) by the Company or Vesicor, in the event any applicable law is in effect making the consummation of the Merger illegal; (iv) by the Company or Vesicor, if the other party has breached any of its respective representations, warranties, agreements or its respective covenants contained in the Business Combination Agreement, such failure or breach would render certain conditions precedents to the Closing incapable of being satisfied, and such breach or failure is not cured by the time allotted; (v) by the Company and Vesicor, by mutual consent; (vi) by Vesicor if the Company Stockholder approval is not obtained; (vii) by the Company if the Vesicor

Stockholder Approval is not obtained by October 1, 2024; (viii) by the Company if, in the Company’s reasonable discretion, Vesicor’s PCAOB audited financial statements reflect a material deterioration in Vesicor’s financial condition as compared to the financial statements delivered to the Company before the Merger Agreement was signed; (ix) by the Company if, in the Company’s sole discretion, the Company is not satisfied with the results of its due diligence investigation; and (x) by the Company, at any time prior to obtaining the Company Stockholder Approval, in order to enter into any Business Combination Proposal that the Board of Directors of the Company determines in good faith to be more favorable than the Merger and reasonable capable of being completed; provided, however, in the case of (ii) and (iii), such ability to terminate is only available if failure by the party seeking to terminate the Business Combination Agreement to fulfill any obligation under the Business Combination Agreement has not been the primary cause of, or primarily resulted in, as applicable, the failure of the Closing to occur.

Governance

The initial board of directors of New Vesicor following the Closing will consist of five members, of which one will be designated by Sponsor and the remaining four will be designated by Vesicor, with at least three of such designees qualifying as independent directors. Executive management of Vesicor will become the executive management of New Vesicor following the Closing.

Ancillary Agreements

The Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including a registration rights agreement pursuant to which New Vesicor will be required to register for resale securities held by the stockholders party thereto, and a lock-up agreement pursuant to which the Company and certain shareholders of Vesicor will agree, subject to customary exceptions, not to transfer the shares of New Vesicor Common Stock received by them in consideration for the Merger for a period of one year following the Closing.

Other Matters

A copy of the Business Combination Agreement will be filed by amendment on Form 8-K/A to this Current Report within four business days of the date hereof as Exhibit 2.1, and the foregoing description of the Business Combination and the Merger is qualified in its entirety by reference thereto. The Business Combination Agreement will be filed to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the parties to the Business Combination Agreement. In particular, the representations, warranties, covenants and agreements contained in the Business Combination Agreement, which were made only for purposes of the Business Combination Agreement and as of specific dates, were solely for the benefit of the parties to the Business Combination Agreement, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Business Combination Agreement instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors, security holders and reports and documents filed with the SEC. Investors and security holders are not third-party beneficiaries under the Business Combination Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Business Combination Agreement. In addition, the representations, warranties, covenants and agreements and other terms of the Business Combination Agreement may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties and other terms may change after the date of the Business Combination Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Forward-Looking Statements

Certain statements included in this Current Report on Form 8-K that are not historical facts are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” “project,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding the Company’s and Vesicor’s expectations with respect to the satisfaction of the closing conditions to the Merger and the timing of the completion of the Merger. These statements are based on various assumptions, whether or not identified in this Current Report on or the exhibits hereto, and on the current expectations of the respective management of the Company and Vesicor and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Company and Vesicor. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic business, market, financial, political, and legal conditions; the inability of the parties to successfully or timely consummate the proposed Merger, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed Merger or that the approval of the stockholders of the Company or Vesicor is not obtained; failure to realize the anticipated benefits of the proposed Merger; risks related to the performance of Vesicor’s business; the development, effects and enforcement of laws and regulations; Vesicor’s ability to manage future growth; Vesicor’s ability to develop new products and solutions and bring them to market in a timely manner; the effects of competition on Vesicor’s business; the amount of redemption requests made by the Company’s stockholders; the ability of the Company or Vesicor to obtain financing in connection with the Merger or in the future; the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries; the ability of the Company to remain listed on Nasdaq and the ability of the

post-combination company to obtain or maintain a stock exchange listing; the ability of the Company to amend its amended and restated certificate of incorporation to extend the time by which it must complete an initial business combination or liquidate; and those factors discussed in Company’s annual report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 23, 2023 under the heading “Risk Factors,” and other documents the Company has filed, or will file, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither the Company nor Vesicor presently know, or that the Company or Veiscor currently believe are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect the Company’s and Vesicor’s expectations, plans, or forecasts of future events and views as of the date of this Current Report and the exhibits hereto. The Company and Vesicor anticipate that subsequent events and developments will cause the Company’s and Vesicor’s assessments to change. However, while the Company and Vesicor may elect to update these forward-looking statements at some point in the future, the Company and Vesicor specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing the Company’s and Vesicor’s assessments as of any date subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.

No Offer or Solicitation

This Current Report is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed business combination and shall not constitute an offer to sell or a solicitation of an offer to buy any securities, nor shall there be any sale of securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act.
