Pursuant to an Agreement and Plan of Merger dated February 22, 2018 (the “Merger Agreement”) among Blue Buffalo Pet Products, Inc., a Delaware corporation (the “Company”), General Mills Inc., a Delaware corporation (“Parent”), and Bravo Merger Corp., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), Merger Sub merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Parent. The Merger became effective on April 24, 2018 (the “Effective Time”).

At the Effective Time, in accordance with the Merger Agreement, among other things, (i) each issued and outstanding share of common stock of the Company, par value $0.01 per share (the “Common Stock”), was converted into the right to receive $40.00 in cash, without interest (the “Merger Consideration”), other than shares of Common Stock held by Parent, Merger Sub or any other wholly-owned subsidiary of Parent, shares of Common Stock owned by the Company (including shares held in treasury) or any of its wholly-owned subsidiaries, and shares of Common Stock owned by stockholders who have properly exercised and perfected appraisal rights under Delaware law, (ii) each option to acquire shares of Common Stock (“Stock Option”), whether vested or unvested, that was outstanding immediately prior to the Effective Time was cancelled automatically and only entitles the holder of such Stock Option to receive, without interest, an amount in cash equal to the product of (x) the total number of shares of Common Stock subject to such Stock Option multiplied by (y) the excess, if any, of the Merger Consideration over the exercise price of such Stock Option, less applicable tax withholding and (iii) each restricted stock unit of the Company outstanding immediately prior to the Effective Time, whether vested or unvested, was automatically cancelled and only entitles the holder thereof to receive, without interest, an amount in cash equal to the product of (x) the total number of shares of Common Stock subject to the restricted stock unit multiplied by (y) the Merger Consideration, less applicable tax withholding. Immediately prior to the Effective Time, the holding restrictions applicable to each share of restricted stock of the Company outstanding immediately prior to the Effective Time automatically expired and each such share of restricted stock was converted into the right to receive the Merger Consideration.

The foregoing description of the Merger does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2018, and which is incorporated herein by reference.
