PLUG POWER HOSTS CONFERENCE CALL AND WEBCAST TO PRESENT BUSINESS UPDATES

LATHAM, NY – December 4, 2013 – Plug Power Inc. (NASDAQ: PLUG), a leader in providing clean, reliable energy solutions, will today host a conference call and webcast during which CEO Andy Marsh will provide a business update for Plug Power and the Company’s expectations for the remainder of 2013 and for 2014.

Since the October 8^th business updates call, the Company has seen an additional 17.8M USD in bookings. Plug Power is currently in negotiations with large customers on sales agreements to deploy turn-key GenDrive solutions at multiple distribution centers. The Company believes this will significantly impact the fourth quarter bookings, as well as provide a recurring revenue stream from product, service and hydrogen contracts. Plug Power expects orders to range between 30M and 40M USD for the fourth quarter of 2013.

Mr. Marsh will outline the structure of a typical multi-site deal using Plug Power’s turn-key hydrogen solution. Plug Power feels volume in sales orders, paired with management of costs will result in profitability for Plug Power in 2014. As previously stated, Plug Power needs to ship 3,000 units in 2014 to achieve its EBITDAS break even goal.

“Large, multi-site deals will provide a level of validation to customers, suppliers, employees and the investment community,” said Andy Marsh. “As we continue to book more orders during the month of December, Plug Power is on track for a ‘blowout’ quarter.”

Plug Power has scheduled its conference call and webcast today at 10:30 am ET to review the Company’s business updates. Participants are encouraged to join the webcast to access the accompanying slide show presentation.
