Plug Power Inc. outlines two real estate transactions with Stream US Data Centers and provides a cash update as part of a strategic infrastructure optimization initiative. The company amended its New York Gateway Project agreement, fixing the purchase price at $142.0 million, extending the outside closing date to March 31, 2027, enabling an interim land closing, and providing a contractual repurchase right for the land under certain conditions. Stream’s prior $6.5 million escrow deposit will be released to Plug, Stream will add a new $10.0 million escrow deposit, and together with a $5.0 million advance previously received, Stream will have paid $21.5 million against the Gateway purchase price upon escrow release.
Separately, Plug agreed to sell its Graham, Texas Project, including land and 164 MW of grid interconnection assets, for $50.0 million at closing plus a contingent earnout of up to $26.5 million tied to final electrical load capacity. This Texas transaction is expected to allow release of about $14 million of cash collateral and to provide up to roughly $90.5 million of total liquidity, with closing targeted on or about July 31, 2026, subject to conditions. As of June 30, 2026, Plug held approximately $162 million of unrestricted cash and cash equivalents and expects these transactions to contribute to more than $80 million in near-term incremental liquidity within a broader initiative targeting over $275 million of aggregate liquidity improvement.
