This Amendment No. 3 (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 subject to the 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

Items 1 through 9 and 11 of the Schedule TO are hereby amended and supplemented as follows:

At one minute after 11:59 p.m. Eastern Time on May 27, 2022, the Offer expired. Purchaser was advised by Broadridge Corporate Issuer Solutions, Inc., in its capacity as depository for the Offer, that, as of the expiration of the Offer, a total of 18,471,314 Shares were validly tendered and not validly withdrawn in accordance with the terms of the Offer, representing approximately 83.8% of the Shares outstanding as of the expiration of the Offer.

As of the expiration of the Offer, the number of Shares validly tendered and not validly withdrawn pursuant to the Offer satisfied the Minimum Condition, as defined in the Offer to Purchase, and all other conditions to the Offer were satisfied or waived. Promptly after the expiration of the Offer, Purchaser accepted for payment all of the Shares validly tendered and not validly withdrawn pursuant to the Offer.

As the final step of the acquisition process, Regeneron completed its acquisition of Checkmate by consummating the Merger without the affirmative vote of Checkmate’s stockholders, pursuant to Section 251(h) of the DGCL. At the Effective Time, Purchaser was merged with and into Checkmate, the separate existence of Purchaser ceased, and Checkmate continued as the Surviving Corporation and a wholly owned subsidiary of Regeneron. Each Share outstanding immediately prior to the Effective Time (other than the Excluded Shares and the Converted Shares (each, as defined in the Merger Agreement)) was canceled and converted into the right to receive $10.50 in cash without interest thereon and subject to reduction for any applicable withholding taxes.

As a result of the Merger, the Shares will be delisted and will cease to trade on the Nasdaq Global Market. Regeneron and Purchaser intend to take steps to cause the termination of the registration of the Shares under the Exchange Act and to suspend all of Checkmate’s reporting obligations under the Exchange Act as promptly as practicable.

On May 31, 2022, Regeneron issued a press release announcing the expiration and results of the Offer. The full text of the press release is attached as Exhibit (a)(5)(A) hereto and is incorporated herein by reference.
