This Amendment No. 3 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission on October 22, 2021 (together with this and any subsequent amendments and supplements thereto, the “Schedule TO”) relates to the tender offer by Oyster Acquisition Company Inc., a Delaware corporation (“Purchaser”) and wholly owned subsidiary of Pacira BioSciences, Inc. (“Pacira”), a Delaware corporation, to purchase all of the outstanding shares of common stock, par value $0.001 per share (the “Shares”), of Flexion Therapeutics, Inc., a Delaware corporation (“Flexion”), at an offer price of (i) $8.50 per Share, in cash, net of applicable withholding taxes and without interest, plus (ii) one contingent value right per Share, which represents the right to receive one or more contingent payments of up to $8.00 per Share in the aggregate, in cash, net of applicable withholding taxes and without interest, which amounts will become payable, if at all, if specified milestones are achieved on or prior to December 31, 2030, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated October 22, 2021 (together with any amendments and supplements thereto, the “Offer to Purchase”), and in the related letter of transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal”), copies of which are attached hereto as exhibits (a)(1)(A) and (a)(1)(B), respectively.

All the information set forth in the Offer to Purchase, including Schedule I thereto, and in the Letter of Transmittal, is hereby expressly incorporated in this Schedule TO by reference in response to Items 1 through 9 and Item 11 of this Schedule TO, and is supplemented by the information specifically provided in this Amendment.

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.

Item 11.    Additional Information.

The information set forth in the Offer to Purchase under Section 16 — “Certain Legal Matters; Regulatory Approvals” and Item 11 of the Schedule TO, to the extent such Item incorporates by reference the information contained in the Offer to Purchase, is amended and supplemented by adding the following sentences to the second paragraph under the heading “United States Antitrust Compliance” on page 58 of the Offer to Purchase with the following:

“The initial waiting period under the HSR Act with respect to the Offer expired, effective November 17, 2021, at 11:59 p.m., Eastern Time. Accordingly, the Regulatory Condition has been satisfied. The Offer continues to be subject to the remaining conditions set forth in Section 15 — “Conditions to the Offer.” At any time before or after Purchaser’s acceptance for payment of Shares pursuant to the Offer, if the FTC believes that the Offer may substantially lessen competition in any line of commerce in violation of the U.S. federal antitrust laws, the FTC has the authority to challenge the transaction by seeking a federal court order enjoining the transaction or, if Shares have already been acquired, requiring disposition of such Shares, or the divestiture of assets of Pacira, Flexion or any of their respective subsidiaries or affiliates. The Antitrust Division, U.S. state attorneys general and private persons may also bring legal action under the U.S. federal and state antitrust laws. While Purchaser and Pacira each believes that the consummation of the Offer will not violate any U.S. federal or state antitrust law, there can be no assurance that a challenge to the Offer on antitrust grounds will not be made or, if a challenge is made, what the result will be.”
