Merger Agreement

As disclosed in the Current Report on Form 8-K filed by Immunome with the U.S. Securities and Exchange Commission (the “SEC”) on June 29, 2023, Immunome, entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with Morphimmune and Ibiza Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Immunome (“Merger Sub”).

At the effective time of the Merger (the “Effective Time”), each share of Morphimmune capital stock outstanding immediately prior to the Effective Time, excluding any shares of Morphimmune capital stock held by Morphimmune, Immunome, Merger Sub or any of their respective subsidiaries and any dissenting shares, will be automatically converted solely into the right to receive 0.3042 shares of Immunome Common Stock (the “Shares”) and, if applicable, an amount in cash, rounded to the nearest whole cent, in lieu of any fractional share interest in Immunome Common Stock to which such holder otherwise would have been entitled (after aggregating all fractional shares issuable to such holder).


CUSIP NO. 45257U108		SCHEDULE 13 D		PAGE 4 OF 7

Support Agreements

As disclosed in the Current Report on Form 8-K filed by Immunome with the SEC on June 29, 2023, concurrently with the execution of the Merger Agreement, the executive officers, directors and certain stockholders of Immunome that beneficially own approximately 20% of the outstanding shares of Immunome Common Stock entered into support agreements (the “Support Agreements”) in favor of Morphimmune, providing, among other things, (1) that such officers, directors and stockholders will vote all of their shares of Immunome Common Stock, among other things: (i) in favor of adopting the Merger Agreement and approving the Merger, the issuance of the Shares in the Merger and the other transactions and actions contemplated by the Merger Agreement, (ii) against any proposal made in opposition to, or in competition with, the Merger Agreement or the Merger and (iii) against any acquisition proposal involving a third party; and (2) an irrevocable proxy in favor of Morphimmune for the limited purpose of voting the shares of Immunome Common Stock held by the Supporting Stockholders in accordance with items (i)-(iii) above.

Item 5. Interest in Securities of the Issuer.

The information contained in rows 7, 8, 9, 10, 11, 12 and 13 on the cover page of this Schedule 13D and the footnotes thereto, and the information set forth or incorporated in Items 2, 3 and 4 is incorporated by reference in its entirety into this Item 5.

(a) – (b) As a result of the transactions described in Item 4, as of the date of this Schedule 13D, under the definition of “beneficial ownership” as set forth in Rule 13d-3 under the Exchange Act, Morphimmune may be deemed to have shared voting power with respect to (and therefore beneficially own) 2,659,508 shares of Immunome Common Stock beneficially owned by the Supporting Stockholders, representing approximately 20% of the outstanding shares of Immunome Common Stock (based on the 12,215,018 shares of Immunome Common Stock outstanding as of the close of business on June 27, 2023), which is comprised of (i) 1,558,353 shares of Immunome Common Stock, (ii) 188,888 shares of Immunome Common Stock issuable upon exercise of warrants to purchase shares of Immunome Common Stock, and (iii) and 912,267 shares of Immunome Common Stock issuable upon the exercise of options within 60 days of April 1, 2023. Based on the foregoing, the percentage of shares of Immunome Common Stock that may be deemed to be beneficially owned by Morphimmune as a result of the Support Agreements is approximately 20%.

Except as set forth above, Morphimmune does not beneficially owns any shares of Immunome Common Stock. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any of Morphimmune that it is the beneficial owner of any of the Immunome Common Stock referred to herein for the purposes of Section 13(d) of the Act, or for any other purpose, and such beneficial ownership is expressly disclaimed by Morphimmune. All Supporting Shares are reported to the knowledge of Morphimmune based on the representations of Immunome and the Supporting Stockholders and as reported in Immunome’s Schedule 14A filed with the Securities and Exchange Commission on April 20, 2023. Morphimmune expressly disclaims any assertion or presumption that it and the other persons on whose behalf this Schedule 13D is filed constitute a “group” for the purposes of Section 13(d) of the Exchange Act and the rules thereunder. The filing of this Schedule 13D should not be construed to be an admission that Morphimmune is a member of a “group” for the purposes of Sections 13(d) of the Exchange Act.

The foregoing descriptions of the Merger Agreement and the Support Agreements do not purport to be complete and are qualified in their entirety by reference to such agreements. The Merger Agreement and the form of the Support Agreements are referenced herein as Exhibits 1.01 and 1.02 and are incorporated by reference into this Item 5(a) – (b).


CUSIP NO. 45257U108		SCHEDULE 13 D		PAGE 5 OF 7

(e) Not applicable.
