FOR IMMEDIATE RELEASE

PLUG POWER RECEIVES NASDAQ NOTICE REGARDING NON-COMPLIANCE WITH MINIMUM BID PRICE RULE

LATHAM, NY – October 12, 2012 – Plug Power Inc. (NASDAQ: PLUG), a leader in providing clean, reliable energy solutions, today announced that it received a notice on October 12, 2012 from the NASDAQ Stock Market. The notice stated that the Company was not in compliance with NASDAQ Marketplace Rule 5550(a)(2) because the bid price of the Company’s common stock closed below the required minimum $1.00 per share for the previous 30 consecutive business days. The NASDAQ notice has no immediate effect on the listing of the Company’s common stock.

In accordance with NASDAQ rules, Plug Power has a period of 180 calendar days, until April 10, 2013, to regain compliance with the minimum bid price rule. If at any time before April 10, 2013, the bid price of the Company’s common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, NASDAQ will notify the Company that it has regained compliance with the minimum bid price rule.

In the event the Company does not regain compliance with the Rule prior to the expiration of the 180-day period, NASDAQ will notify the Company that its securities are subject to delisting.  However, the Company may appeal the delisting determination to a NASDAQ hearing panel and the delisting will be stayed pending the panel’s determination. At this hearing, the Company would present a plan to regain compliance and NASDAQ would then subsequently render a decision. The Company is currently evaluating its alternatives to resolve the listing deficiency.
