Item 8.01 Other Events

Extension of Stock Repurchase Program

On November 15, 2012, Board of Directors of Maxygen, Inc. (the “Company” or “Maxygen”) approved the extension of the Company’s current stock repurchase program through December 31, 2013.

Under the stock repurchase program, which was originally scheduled to expire on December 31, 2012, the Company may purchase up to $10.0 million of its common stock. As of September 30, 2012, Maxygen had repurchased approximately 279,000 shares of common stock under this program, at an aggregate purchase price of approximately $1.5 million. From December 2009 through September 2012, Maxygen has repurchased approximately 12.5 million shares of its common stock at an aggregate cost of approximately $67.9 million.

Under the current repurchase program, Maxygen may repurchase its common stock from time to time, in amounts, at prices and at such times as it deems appropriate. Maxygen may make repurchases in the open market, in privately negotiated transactions, in accelerated repurchase programs, in structured share repurchase programs, or pursuant to a 10b5-1 plan. Any repurchases will be conducted in compliance with the SEC’s Rule 10b-18 and applicable legal requirements and will be subject to market conditions and other factors. The program does not obligate Maxygen to acquire any particular amount of common stock and the program may be modified or suspended at any time at the Company’s discretion. Any repurchases will be funded from available cash on hand.

As of September 30, 2012, Maxygen held approximately $82.2 million in cash, cash equivalents and short-term investments.
