Metabolix Announces 1-for-6 Reverse Stock Split

CAMBRIDGE, Mass., May 26, 2015 (GLOBE NEWSWIRE) -- Metabolix, Inc. (Nasdaq:MBLX), an advanced biomaterials company focused on sustainable solutions for the plastics industry, announced today that it will effect a 1-for-6 reverse stock split previously approved by the Company's stockholders at a special meeting held on October 30, 2014. The 1-for-6 reverse stock split will be effective as of the close of business on May 26, 2015 and the Company's common stock will begin trading on a split-adjusted basis on Tuesday, May 27, 2015.

The reverse stock split will reduce the number of shares of the Company's common stock currently outstanding from approximately 135.5 million shares to approximately 22.6 million shares. Proportional adjustments will be made to the Company's outstanding stock options and restricted stock units and to the number of shares issued and issuable under the Company's equity compensation plans. The number of authorized shares of the Company's common stock will remain 250 million shares.

The reverse stock split is intended to increase the market price per share of the Company's common stock to allow the Company to maintain the listing of its common stock on The NASDAQ Capital Market. The Company's common stock will continue to trade on The NASDAQ Capital Market under the symbol "MBLX." The new CUSIP number for the common stock following the reverse stock split will be 591018 882.

Information for Stockholders

Upon the effectiveness of the reverse stock split, each six (6) shares of the Company's issued and outstanding common stock will be automatically combined and converted into one issued and outstanding share of common stock, par value $0.01 per share. The reverse stock split will not modify the rights or preferences of the common stock. No fractional shares of common stock will be issued as a result of the reverse split. Instead, stockholders who otherwise would be entitled to receive fractional shares will be entitled to receive cash in an amount equal to the product obtained by multiplying (i) the closing price of Metabolix common stock on May 22, 2015, by (ii) the number of shares of common stock held by the stockholder that would otherwise have been exchanged for such fractional share interest.
