• A contract to deploy multiple sites with a single food distribution customer using Plug Power's turnkey GenDrive solution which includes products, service, and hydrogen;

"Plug Power has continued to deliver value to material handling customers through its GenDrive product suite," said Andy Marsh, CEO at Plug Power. "Moving forward, as we significantly grow the business, Plug Power will increase its value-add for each customer through building our product base and establishing recurring revenue streams through hydrogen and service.
