Metabolix Granted 180-day Extension by NASDAQ to

WOBURN, Mass., Jan. 03, 2017 (GLOBE NEWSWIRE) -- Metabolix, Inc. (NASDAQ: MBLX ) announced today that it has received a letter from the NASDAQ OMX Group ("Nasdaq") determining that the Company is eligible for an additional 180-calendar day period, until June 26, 2017, to regain compliance with the minimum $1.00 per share bid price required for continued listing under Listing Rule 5550(a)(2). Per the notice of deficiency received on June 30, 2016, Metabolix had a period of 180-calendar days, or until December 27, 2016, to regain compliance with the minimum bid price requirement. Following a review, Nasdaq determined that the Company was eligible to receive an additional 180-day period on the basis that Metabolix still met the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and had provided written notice of its intention to cure the minimum bid price deficiency during the second 180-day compliance period by effecting a reverse stock split, if necessary.

The Company's shares will continue to trade on Nasdaq under the symbol “MBLX.” Metabolix plans to change the company name to Yield10 Bioscience, Inc. and its ticker symbol to “YTEN” in January 2017.  This change will reflect the Company’s plan to move forward focusing exclusively on the Yield10 Bioscience mission to address the challenge of global food security, directing its resources toward breakthrough bioscience and innovation to position Yield10 as a leader in novel crop yield trait discovery.
