On September 10, 2015, Coherus BioSciences, Inc. (the “Company”) entered into and consummated a Stock Purchase Agreement (the “Purchase Agreement”) with Baxalta Incorporated, Baxalta US Inc. and Baxalta GmbH (together, “Baxalta”). Pursuant to the Purchase Agreement, the Company sold to Baxalta an aggregate of 390,167 shares of common stock (the “Shares”) for aggregate gross proceeds of approximately $10 million (the “Offering”). The purchase price for each Share was $25.63, which is equal to the closing trading price on the NASDAQ Global Market on the day of pricing, September 9, 2015.

In connection with the Purchase Agreement, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with Baxalta GmbH. Pursuant to the Registration Rights Agreement, the Company agreed to prepare and file a registration statement with the Securities and Exchange Commission (the “SEC”) no later than December 4, 2015 for purposes of registering the resale of the Shares and any shares of common stock issued as a dividend or other distribution with respect to the Shares. The Company agreed to use its reasonable best efforts to cause this registration statement to be declared effective by the SEC as soon as practicable, and in any event, within 60 days after its filing. The Company also agreed, among other things, to indemnify the selling holders under the registration statement from certain liabilities and to pay all fees and expenses (excluding underwriting discounts and selling commissions) incident to the Company’s obligations under the Registration Rights Agreement.

The Offering is exempt from registration pursuant to the exemption for transactions by an issuer not involving any public offering under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and Regulation D under the Securities Act.

The securities sold and issued in connection with the Purchase Agreement are not registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration with the SEC or an applicable exemption from the registration requirements.

The foregoing description of the transaction is only a summary and is qualified in its entirety by reference to the Purchase Agreement and the Registration Rights Agreement, copies of which are attached hereto as Exhibits 10.1 and 4.1, respectively, and are incorporated herein by reference.

The information called for by this item is contained in Item 1.01, which is incorporated herein by reference.
