Eos Energy Stockholders Approve All Proposals at 2026 Annual Meeting

Increased share authorization provides the capital structure flexibility to fund the planned Frontier Power USA Investment

EDISON, N.J., June 05, 2026 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE), America’s leading innovator in designing, manufacturing, and providing zinc-based long duration energy storage (LDES) systems sourced and manufactured in the United States, today announced that stockholders approved all five proposals presented at the Company’s 2026 Annual Stockholders’ Meeting held on June 3, 2026.

Stockholders representing approximately 77.6% of the Company’s outstanding shares (or 263,431,701 shares) participated and demonstrated strong support for the Company’s proposals, including the election of Jeff Bornstein, Claude Demby, and Nathaniel Fick for three-year terms on the Board of Directors, ratification of the appointment of Eos’ independent registered public accounting firm, approval of the advisory “Say on Pay” management proposal, approval of the increase in the authorized shares of common stock of the Company, and approval of the amendment to the Company’s long-term incentive plan. The Company thanks its stockholders for their participation and continued support.

Stockholders approved an increase in the authorized shares of common stock from 600,000,000 to 800,000,000. The increase does not result in the immediate issuance of any shares. It provides the Company with the flexibility to support previously disclosed strategic and financing initiatives, including a rights offering to facilitate its planned investment in Frontier Power USA, while also allowing existing shareholders to participate. The Company expects to provide additional details regarding the structure, timing and terms of any offering at a later date. Approval of this proposal required the affirmative vote of 66.67% of all outstanding shares, a higher threshold than the other proposals.

Frontier Power USA is designed to combine Eos’ vertically integrated technology deployment with a financing platform, creating a more streamlined path to market for long-duration energy storage projects. Through a single platform, customers can access the technology, financing, insurance, guarantees, and operating expertise required to execute projects successfully. This integrated approach is designed to improve project execution, enhance project bankability, and accelerate project deployment.

“Eos is at a pivotal stage in its growth, and the support from our stockholders at our 2026 annual meeting positions us to continue pursuing strategic opportunities, including our planned investment in Frontier Power USA,” said Joe Nigro, Chairman of Eos. “On behalf of the Board and management team, I would like to thank our stockholders for their continued support and participation. We remain focused on executing our strategy, expanding the deployment of Eos technology and creating long-term value for our stockholders.”

“The support we received positions us to advance Frontier Power USA and bring a fully integrated platform combining technology, financing, and execution capabilities to the long-duration storage market,” said Joe Mastrangelo, Chief Executive Officer of Eos. “The increase in authorized shares provides Eos with strategic flexibility to pursue growth opportunities and enables us to move with discipline as we scale the business, invest in our capabilities, and create long-term value for our stockholders.”

Further information on potential risks that could affect actual results will be included in the subsequent periodic and current reports and other filings that the Company makes with the Securities and Exchange Commission from time to time. Moreover, the Company operates in a very competitive and rapidly changing environment, and new risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this press release.

Forward-looking statements speak only as of the date they are made. Should one or more of these risks or uncertainties materialize or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.
