This Amendment No. 4 is being filed jointly by (a) Newtyn Management, LLC (“Newtyn Management”), a New York limited liability company; (b) Noah G. Levy, a citizen of the United States of America; (c) Newtyn Partners, LP (“Newtyn Partners”), a Delaware limited partnership; (d) Newtyn TE Partners, LP (“Newtyn TE”), a Delaware limited partnership; (e) Newtyn Capital Partners, LP (“NCP”), a Delaware limited partnership; and (f) Ledo Capital, LLC (“Ledo”), a New York limited liability company (each a “Reporting Person” and collectively, referred to as the “Reporting Persons”) to supplement and amend the Schedule 13D filed with the Securities and Exchange Commission on September 19, 2019, as amended September 30, 2019, as amended July 27, 2020, as amended November 24, 2020 (the “prior Schedule 13Ds”) with respect to beneficial ownership of the shares of Common Stock, $0.01 par value per share (the “Common Stock”) of Merrimack Pharmaceuticals, Inc. (the “Issuer”). The prior Schedule 13Ds, as amended and supplemented by this Amendment, are referred to herein as “this Schedule 13D.” Except as specifically provided herein, this amendment does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used herein shall have the meanings ascribed to them in the prior Schedule 13Ds.

 

Item 3 Source and Amount of Funds

 

Item 3 is hereby supplemented as follows:

 

The Reporting Persons used working capital to purchase the additional 354,587 shares of the Issuer’s Common Stock purchased in open market transactions. The total purchase price for the shares of Common Stock was approximately $2,363,626.

 

Item 5. Interest in Securities of the Issuer

 

Item 5 is hereby supplemented as follows:

 

“Group” Status

 

As a result of their agreement with the Western Standard Parties to vote their respective shares of Common Stock to support the Issuer’s slate of director nominees and proposals in connection with the Annual Meeting, as described in Item 4 of the prior Schedule 13Ds, and by entering into the Cooperation Agreement, the Reporting Persons have formed a “group” for purposes of Section 13 (d)(1) of the Exchange Act and the rules promulgated thereunder because of their agreement to vote jointly. The members of this group are Mr. Levy, Newtyn Management, Newtyn Partners, Newtyn TE, NCP, Ledo, Mr. Andersen, Western Standard, Western Standard Partners, LP and Western Standard Partners QP, LP (collectively, the “13D Group”).

 

Each of Mr. Andersen and Western Standard (collectively, the “Western Standard Reporting Persons”) as of the date of this Schedule 13D also beneficially owns more than 5% of the Issuer’s Common Stock through their indirect voting and dispositive power over the shares of Common Stock held by the Funds. The Western Standard Reporting Persons filed a Schedule 13D on September 19, 2019 (as may be amended from time to time, the “Western Standard Schedule 13D filing”) to report their ownership of and transactions in the Common Stock and the interactions and agreements of the Western Standard Reporting Persons with the Board, members of management and the Reporting Persons substantially as described in this Schedule 13D.

 

 

 

 

As the 13D Group is deemed to have acquired beneficial ownership of the aggregate amount of the Issuer’s Common Stock that the 13D Group members beneficially owns, the 13D Group is deemed to beneficially own 3,062,539 shares of Common Stock representing 28.6% of the Issuer’s Common Stock outstanding for voting purposes. However, none of the Newtyn Parties have the ability to direct the acquisition or disposition or, except through the Cooperation Agreement, voting of the securities held by the Western Standard Parties, and none of the Western Standard Parties have the ability to direct the acquisition or disposition or, except through the Cooperation Agreement, voting of the securities held by the Newtyn Parties.

 

(a) & (b) The information relating to the beneficial ownership of Common Stock by each of the Reporting Persons set forth in Rows 7 through 13 of the cover pages hereto is incorporated by reference.

 

As of January 12, 2022, the Reporting Persons are the beneficial owners of 1,663,612 shares of Common Stock. Such number of shares of Common Stock represent 12.4% of the shares of Common Stock outstanding based on 13,410,243 shares of Common Stock outstanding, as of November 2, 2021, which number the Issuer reported in its Form 10-Q for the quarterly period ending September 30, 2021, filed with the U.S. Securities and Exchange Commission on November 4, 2021.

 

As of January 17, 2023, the Reporting Persons are the beneficial owners of 1,873,694 shares of Common Stock. Such number of shares of Common Stock represent 14.0% of the shares of Common Stock outstanding based on 13,410,243 shares of Common Stock outstanding, as of November 1, 2022, which number the Issuer reported in its Form 10-Q for the quarterly period ending September 30, 2022, filed with the U.S. Securities and Exchange Commission on November 3, 2022.

 

As of the filing date, the Reporting Persons are the beneficial owners of 1,873,694 shares of Common Stock. Such number of shares of Common Stock represent 13.1% of the shares of Common Stock outstanding based on 14,320,953 shares of Common Stock outstanding, as of October 31, 2023, which number the Issuer reported in its Form 10-Q for the quarterly period ending September 30, 2023, filed with the U.S. Securities and Exchange Commission on November 2, 2023.

 

To the extent required as a result of the Reporting Persons’ status as members of the 13D Group, the information relating to the beneficial ownership of Common Stock by each of the Western Standard Reporting Persons set forth in Rows 7 through 13 of the cover pages of the Western Standard Schedule 13D filings is incorporated by reference into this Item 5 (a) and (b). Such information, combined with the holdings of the Reporting Persons, would result in the 13D Group having voting power equivalent to a combined beneficial ownership of approximately 28.6% of the Issuer’s Common Stock outstanding for voting purposes.
