Exhibit 99.1

Nir Brenmiller Assumes Role of Chief ExecutiveOfficer of Brenmiller Energy

Shareholder Approval Clears the Way for LeadershipTransition as Company Advances BrenX Strategy to Develop and Own Integrated Energy Infrastructure

TEL AVIV, Israel – July 30, 2026 – Brenmiller Energy Ltd. (Nasdaq: BNRG) (“Brenmiller,” “Brenmiller Energy” or the “Company”), a provider of integrated power and heat solutions for industrial and utility customers built around its proprietary thermal energy storage (“TES”) technology, today announced that the Company’s shareholders approved all proposals presented at the Company’s Annual and Special General Meeting of Shareholders held on July 29, 2026 (the “Meeting”).

With shareholder approval obtained, Mr. Nir Brenmiller assumes the role of Chief Executive Officer effective as of the approval of the Company’s shareholders at the Meeting. Company founder Avi Brenmiller will continue to serve as Chairman of the Board of Directors.

“Nir has been central to building this Company for more than a decade, and the Board’s confidence in him is complete,” said Avi Brenmiller, Founder and Chairman of the Board of Brenmiller Energy. “Brenmiller today is a very different company than the one we founded. We proved the technology, built the world’s first gigafactory dedicated to thermal energy storage, and are now moving into owning the energy infrastructure our industrial customers need. Nir has led much of that work as Deputy CEO and Chief Operating Officer, and he is the right leader for this next chapter. I look forward to continuing to work alongside him as Chairman.”

“I am honored to step into this role at a defining moment for the Company,” said Nir Brenmiller. “BrenX changes both what we sell and how we generate revenue, moving us from one-time equipment sales toward owning energy assets designed to produce recurring cash flow. Our near-term priorities are clear: expand our first industrial energy resource center in Hungary, convert our pipeline of commercial opportunities into signed projects, and strengthen our balance sheet. We believe our technology is reaching commercial maturity at exactly the right time. European industry is seeking reliable, clean alternatives to natural gas as geopolitical uncertainty continues to drive significant price volatility. We believe BrenX is well positioned to capitalize on this opportunity by delivering resilient, cost-effective energy infrastructure that helps customers reduce both emissions and energy risk. We have proven technology, real assets on the ground and a defined plan, and I expect to be measured on execution.”

The leadership transition follows a series of steps to advance the BrenX strategy, including the purchase of an operating 1.2 MWp photovoltaic facility in Kaposszekcső, Hungary; the signing of a term sheet to acquire adjacent industrial land and related photovoltaic infrastructure intended to expand the site into the Company’s first BrenX industrial energy resource center; and the recently announced waiver from the European Investment Bank as the parties advance toward a full and final settlement of the Company’s March 2021 credit facility, which the Company expects would reduce its debt if completed.

Separately, the Company’s shareholders approved a change of the Company’s name to “BrenX” or any similar name as approved by the Israeli Registrar of Companies. The name change will become effective only upon approval by the Israeli Registrar of Companies, and the Company will provide additional details at that time.
