Explanatory Note:

 

This Amendment No. 3 (this “Amendment No. 3”) amends and supplements the statement on Schedule 13D initially filed on December 15, 2020 (the “Original Schedule 13D”), as amended and restated by Amendment No. 1 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2023 (“Amendment No. 1”) and by Amendment No. 2 filed with the SEC on May 10, 2023 (“Amendment No. 2”, and together with the Original Schedule 13D, Amendment No. 1 and this Amendment No. 3, the “Schedule 13D”), that relates to the common stock, par value $0.0001 per share (the “Common Shares”), of Kinnate Biopharma Inc., a Delaware corporation (the “Issuer”), by Foresite Capital Fund IV, L.P. (“FCF IV”), Foresite Capital Management IV, LLC (“FCM IV”), Foresite Capital Fund V, L.P. (“FCF V”), Foresite Capital Management V, LLC (“FCM V”), Foresite Capital Opportunity Fund V, L.P. (“FCOF V”), Foresite Capital Opportunity Management V, LLC (“FCOM V”) and James B. Tananbaum (“Tananbaum” and together with FCF IV, FCM IV, FCF V, FCM V, FCOF V and FCOM V, the “Reporting Persons”).

 

Except as provided herein, this Amendment No. 3 does not modify any of the information previously reported on the Schedule 13D.

 

ITEM 4. PURPOSE OF TRANSACTION.

 

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

 

On November 13, 2023 (i) FCF IV, FCF V and FCOF V (collectively, “Foresite”) and (ii) OrbiMed Private Investments VII, LP, OrbiMed Private Investments VIII, LP, OrbiMed Asia Partners IV, L.P., OrbiMed Genesis Master Fund, L.P. and OrbiMed Partners Master Fund Limited (collectively, “OrbiMed”, and together with Foresite, the “Investors”) submitted to the board of directors of the Issuer (the “Board”) a non-binding expression of interest letter (the “Letter”) setting forth an intent to explore and evaluate a potential acquisition of all of the outstanding Common Shares that are not owned by the Investors or their affiliates in a going-private transaction. A copy of the Letter is filed as Exhibit 1 to this Amendment No. 3, and the information set forth in the Letter is incorporated by reference herein.

 

The Letter may result in one or more of the transactions, events or actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including, without limitation, an acquisition of additional securities of the Issuer, an extraordinary corporate transaction (such as a merger) involving the Issuer, delisting of the Common Shares from the Nasdaq Global Select Market and other material changes in the Issuer’s business or corporate structure.

 

  

 

 

CUSIP No. 49705R105 SCHEDULE 13D Page 10 of 13

 

 

The Letter stated that any transaction, once structured and agreed upon, would be conditioned upon, among other things, the (x) approval of the transaction by a properly constituted special committee composed of independent and disinterested directors of the Issuer appointed by the Board, with assistance from legal and financial advisors and (y) approval of the stockholders holding at least a majority of all the issued and outstanding Common Shares not held by the Investors or their affiliates.

 

The Letter is non-binding in nature and does not obligate in any way the Investors or the Issuer to negotiate or enter into definitive documentation with respect to a transaction or otherwise complete a transaction. The Letter states that the Investors are only interested in acquiring the outstanding Common Shares that they do not already own, and are not interested in selling their Common Shares to another party or in participating in an alternative change of control transaction involving the Company.

 

The foregoing description of the Letter does not purport to be complete and is qualified in its entirety by reference to the full text of the Letter. Neither the Letter nor this Schedule 13D is meant to be, nor should be construed as, an offer to buy or the solicitation of an offer to sell any of the Issuer’s securities.

 

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may from time to time and at any time in the future depending on various factors, including, without limitation, the outcome of any discussions referenced in this Schedule 13D, as may be amended from time to time, the Issuer’s financial position and strategic direction, actions taken by the Board, price levels of the Issuer’s securities, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to the investment in the Issuer as they deem appropriate.

 

 

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

 

Item 5 of the Schedule 13D is hereby amended and supplemented by adding the following:

 

Based on the events and transactions described above, the Reporting Persons may be deemed to constitute a “group” (within the meaning of Section 13(d) of the Act) with OrbiMed and its affiliated investment funds and persons that hold Common Shares of the Issuer but do not affirm the existence of any such “group.” The following table sets forth the beneficial ownership of Common Shares held by OrbiMed and certain of its affiliates listed below (each, an “OrbiMed Holder” and, collectively, the “OrbiMed Holders”) based on a Schedule 13D/A filed by the OrbiMed Holders with the SEC on May 8, 2023. The Reporting Persons expressly disclaim beneficial ownership of any Common Shares held or which may be acquired by any OrbiMed Holder.
