Item 3. Source and Amount of Funds or Other Consideration

On August 4, 2023, the Issuer consummated its merger with Pionyr Immunotherapeutics, Inc., a Delaware corporation (“Pionyr”), in accordance with the terms of the Agreement and Plan of Merger, dated August 4, 2023 (the “Merger Agreement”), by and among the Issuer, Portsmouth Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Issuer (“First Merger Sub”), Portsmouth Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Issuer (“Second Merger Sub”), Pionyr, and Fortis Advisors LLC, as securityholder agent. Pursuant to the Merger Agreement, First Merger Sub merged with and into Pionyr, pursuant to which Pionyr was the surviving corporation and became a wholly owned subsidiary of the Issuer (the “First Merger”). Immediately following the First Merger, Pionyr merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity (together with the First Merger, the “Merger”).

Prior to the Merger, OrbiMed Private Investments VI, LP (“OPI VI”), a limited partnership organized under the laws of Delaware, was a stockholder of Pionyr and OPI VI, OrbiMed Genesis Master Fund, L.P. (“Genesis”), a limited partnership organized under the laws of the Cayman Islands, and Worldwide Healthcare Trust PLC (“WWH”), a publicly-listed investment trust organized under the laws of England, were stockholders of the Issuer.

Pursuant to the terms of the Merger Agreement, in return for the Class A shares of Pionyr held by OPI VI, OPI VI received 153,121 Shares, 353,192 shares of Series A Preferred Stock (“Series A Preferred Stock”), and 9,579,040 contingent value rights (“CVRs”).

Following approval by the Issuer’s stockholders of the conversion of the Series A Preferred Stock into Shares, each share of Series A Preferred Stock is automatically convertible into one Share; provided that if a holder of the Series A Preferred Stock was a holder of non-voting Shares prior to such conversion, such holder will receive non-voting Shares to the extent such conversion would result in such holder beneficially owning more than 9.99% of the outstanding Shares. Each non-voting Share is convertible into one Share at any time at the option of the holder without payment or additional consideration, subject to a 9.99% beneficial ownership limitation that may be increased or decreased by the holder upon 61 days’ notice to the Issuer.

Subject to the terms of the CVR Agreement (as defined below), as more particularly described in Item 6 below, each CVR entitles the holder thereof to receive certain cash and/or stock payments from 50% of the net proceeds, if any, related to the disposition of Pionyr’s legacy assets within two years following the Closing Date (as defined in the Merger Agreement).

The source of funds for such purchases was the working capital of OPI VI.

As a result of the transactions described in this Item 3, OrbiMed GP, as the general partner of OPI VI, as more particularly described in Item 6 below, may be deemed to be the beneficial owner of approximately 5.3% of the outstanding Shares and OrbiMed Genesis, as the general partner of Genesis, as more particularly described in Item 6 below, may be deemed to be the beneficial owner of approximately 0.2% of the outstanding Shares. OrbiMed Advisors, as the managing member of OrbiMed GP and OrbiMed Genesis, as more particularly described in Item 6 below, may be deemed to be the beneficial owner of approximately 5.5% of the outstanding Shares. OrbiMed Capital, as the investment advisor of WWH, as more particularly described in Item 6 below, may be deemed to be the beneficial owner of 2.3% of the outstanding Shares. None of the Reporting persons have acquired or disposed of any Share since August 4, 2023.

Item 4. Purpose of Transaction

This Statement relates to the acquisition of Shares by the Reporting Persons. The Shares acquired by the Reporting Persons were acquired for the purpose of making an investment in the Issuer and not with the intention of acquiring control of the Issuer’s business on behalf of the Reporting Persons’ respective advisory clients.

The Reporting Persons from time to time intend to review their investment in the Issuer on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s Shares in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time. If the Reporting Persons believe that further investment in the Issuer is attractive, whether because of the market price of Shares or otherwise, they may acquire Shares or other securities of the Issuer either in the open market or in privately negotiated transactions. Similarly, depending on market and other factors, the Reporting Persons may determine to dispose of some or all of the Shares currently owned by the Reporting Persons or otherwise acquired by the Reporting Persons either in the open market or in privately negotiated transactions.

Except as set forth in this Schedule 13D, the Reporting Persons have not formulated any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries, (c) a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries, (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the Issuer’s capitalization or dividend policy of the Issuer, (f) any other material change in the Issuer’s business or corporate structure, (g) any change in the Issuer’s charter or bylaws or other instrument corresponding thereto or other action which may impede the acquisition of control of the Issuer by any person, (h) causing a class of the Issuer’s securities to be deregistered or delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act or (j) any action similar to any of those enumerated above.

Demand Registration Rights

At any time beginning six months following the date of the effective date of the registration statement of the Issuer’s initial public offering, the holders of at least 40% of the registrable securities then outstanding of the Issuer may make a written request that the Issuer register at least 20% their registrable securities (or a lesser percent if the anticipated aggregate offering price, net of expenses, would exceed $10 million).

Support Agreement

In connection with the execution of the Merger Agreement, the Issuer and Pionyr entered into stockholder support agreements (the “Support Agreements”) with certain stockholders of the Issuer, including OPI VI, Genesis, and WWH. The Support Agreements provide that, among other things, each of the stockholders has agreed to vote, or cause to be voted, at the Issuer’s stockholders’ meeting to be held in connection therewith all of the Shares owned by such stockholder in favor of (i) the approval of the conversion of the Series A Preferred Stock into Shares in accordance with Nasdaq Listing Rule 5635(a), and, if deemed necessary by the Issuer, (ii) the approval of an amendment to the certificate of incorporation of the Issuer to authorize sufficient Shares for the conversion of the Series A Preferred Stock issued pursuant to the Merger Agreement.

The CVRs are not transferable, except in certain limited circumstances as provided in the CVR Agreement, will not be certificated or evidenced by any instrument, and will not be registered with the SEC or listed for trading on any exchange.

The foregoing descriptions of the Investors’ Rights Agreement, the Support Agreements, the Lock-Up Agreements, and the CVR Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the Investors’ Rights Agreement, the Support Agreements, the Lock-Up Agreements, and the CVR Agreement, which are filed as Exhibit 2, Exhibit 3, Exhibit 4, and Exhibit 5 respectively, and are incorporated herein by reference.
