Fellow Plug Power Stockholders,

Thank you for your investment and continued support of Plug Power.

You have an important opportunity to shape our company's future by voting on two charter amendments at our upcoming Special Meeting of Stockholders. These proposals are essential to ensuring that Plug has the financial flexibility and modern governance tools needed to execute our strategy, meet existing contractual commitments, and continue growing our stake in the global hydrogen economy.

· Proposal 1: Amendment to Modernize Voting Standards

Proposal #1 would modernize the Company's voting standards by aligning the Company's charter with current Delaware corporate law. If approved, this amendment would allow certain future charter amendments to be approved by a majority of votes cast, where permitted under the Delaware General Corporation Law (DGCL).

This change ensures that outcomes are determined by the stockholders who actively participate in the voting process, rather than by shares that are not voted at all. Under the Company's current charter, shares that are not voted effectively have the same impact as votes cast against a proposal, which can prevent proposals from passing even when a clear majority of voting stockholders support them.

By aligning with current Delaware standards, this proposal helps ensure that stockholder intent is reflected more accurately and that the Company is governed in a manner consistent with modern corporate practices.

· Proposal 2 – Increase in Authorized Shares of Common Stock

Proposal #2 is essential to the Company's ability to meet its financial obligations, maintain operating flexibility, and continue executing its business plan. Approval of this proposal would increase the number of authorized shares of common stock, providing the Company with the flexibility required to satisfy obligations as they come due and to support the ongoing needs of the business.

If Proposal #2 is not approved, the Company will implement a reverse stock split in order to create sufficient share availability to meet its financial obligations and maintain business flexibility.

*Approval of the increase in authorized shares does not result in the immediate issuance of new shares or have an immediate impact on our shares outstanding.*

We understand you may be concerned about potential dilution. These proposals do not immediately issue *any* new shares. Upon approval, Plug would have tools to manage its balance sheet responsibly. Without approval, Plug would need to pursue alternatives such as a reverse stock split. Your Board and management team remain committed to disciplined capital allocation and to using any newly authorized shares in a manner that supports sustainable value creation.

***Voting FOR the proposals allows Plug to move forward in a stronger position. If the proposal to increase authorized shares is not approved by stockholders, Plug will proceed with a reverse stock split as previously authorized.***

How you can help:

Voting is quick and easy. Please locate your proxy materials and voting control number and vote "FOR" all proposals in line with the Board's recommendation. If you have not received proxy materials, via mail or email, and held Plug Power shares as of December 12, 2025 please contact your bank or broker and request the control number specific to your account to vote online.

If you need additional assistance voting please contact our Proxy Solicitor, Sodali & Co, at (833) 924-7453.

Thank you again for your investment in Plug Power and your attention to this pivotal special meeting.
