This Amendment No. 1 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed by Scandinavian Acquisition Sub, Inc., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Regeneron Pharmaceuticals, Inc., a New York corporation (“Regeneron”), with the U.S. Securities and Exchange Commission on May 2, 2022 (together with any subsequent amendments and supplements thereto, the “Schedule TO”). The Schedule TO relates to the offer by Purchaser to purchase all of the outstanding shares of common stock, par value $0.0001 per share (“Shares”), of Checkmate Pharmaceuticals, Inc., a Delaware corporation (“Checkmate”), at a price of $10.50 per share, to be paid to the seller in cash, without interest, and subject to reduction for any applicable withholding taxes, upon the terms and conditions set forth in the offer to purchase, dated May 2, 2022 (the “Offer to Purchase”), a copy of which is attached as Exhibit (a)(1)(A), and in the related letter of transmittal (the “Letter of Transmittal”), a copy of which is attached as Exhibit (a)(1)(B), which, as each may be amended or supplemented from time to time, collectively constitute the “Offer.”

 

Except as otherwise set forth in this Amendment, the information set forth in the Schedule TO remains unchanged and is incorporated herein by reference to the extent relevant to the items in this Amendment. Capitalized terms used but not defined herein have the meanings ascribed to them in the Schedule TO.

 

Items 1 through 9 and Item 11

 

The information set forth in the Offer to Purchase under “The Tender Offer—Section 16—Certain Legal Matters; Regulatory Approvals” and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented as follows:

 

The following paragraph replaces in its entirety the first paragraph in the subsection entitled “Compliance with the HSR Act” which begins on page 52 of the Offer to Purchase:

 

“Under the HSR Act, and the related rules and regulations promulgated thereunder, certain transactions, including the Offer, may not be consummated until notifications have been given and information has been furnished to the FTC and the DOJ and all statutory waiting period requirements have been satisfied. On April 25, 2022, each of Regeneron and Checkmate filed Notification and Report Forms under the HSR Act with the FTC and the DOJ in connection with the purchase of Shares in the Offer. At 11:59 p.m., Eastern Time, on May 10, 2022, the waiting period applicable to the Offer under the HSR Act expired. Accordingly, the portion of the conditions to the Offer relating to the expiration or termination of the waiting period under the HSR Act has been satisfied.”

 

The following paragraph is added at the end of such section on page 54 of the Offer to Purchase:

 

“Securityholder Litigation. On May 5, 2022, a complaint was filed in the United States District Court for the Eastern District of New York captioned Hopkins v. Checkmate Pharmaceuticals, Inc., et al., 1:22-cv-02582 (E.D.N.Y.) (which we refer to as the “Merger Action”). The Merger Action alleges that the Schedule 14D-9 misrepresents and/or omits certain purportedly material information relating to the analyses performed by Checkmate’s financial advisor in connection with the Merger. The Merger Action asserts violations of Sections 14(d) and 14(e) of the Exchange Act, and Rule 14d-9 promulgated thereunder, against all defendants (Checkmate and the Checkmate Board of Directors), and violations of Section 20(a) of the Exchange Act against Checkmate’s directors. The Merger Action seeks, among other things, an injunction enjoining the consummation of the Merger, costs of the action, including plaintiffs’ attorneys’ fees and experts’ fees, and other relief the court may deem just and proper. Checkmate has also received a demand letter from a purported Checkmate shareholder (which we refer to as the “Demand”) requesting that Checkmate provide additional disclosures in connection with the Merger. The defendants believe the claims asserted in the Merger Action and the Demand are without merit. Additional lawsuits may be filed against Checkmate, the Checkmate Board of Directors, Regeneron and/or Purchaser, and additional demand letters may be received, in connection with the transactions contemplated by the Merger Agreement, including the Offer and the Merger (which we refer to as the “Transactions”), the Schedule TO and the Schedule 14D-9. If additional similar complaints are filed or additional similar demand letters are received, absent new or significantly different allegations, Purchaser will not necessarily disclose such additional filings or letters.”
