Brenmiller Energy Chief Executive Officer Highlights Strategic Initiative to Unlock Value and Accelerate Growth

Brenmiller Energy Ltd. ("Brenmiller", "Brenmiller Energy" or the "Company") (NASDAQ:BNRG), a leading global energy provider of thermal energy storage ("TES") solutions to industrial and utility markets, today issued a Letter to Shareholders from its Chief Executive Officer, Avi Brenmiller.

Dear Shareholders,

The April 28th outage affecting Spain and surrounding countries further reinforces the need of our technology and validates both our solution and our strategic focus on these geographies. This event highlights the critical importance of reliable energy storage solutions, emphasizing the relevance and value of our offerings.

After more than a decade of innovation, $118 million in strategic investments, and field-proven deployments across three continents, our TES systems are not just operational— they're leading the market. We've collaborated with some of the world's most respected energy leaders, we've commissioned and are building over 100 MWh of projects, and we're on the cusp of completing our flagship Tempo project in Israel, replacing fossil fuel boilers with our clean heat battery technology.

This progress is not aspirational. It's tangible, it's measured, and it's accelerating.

Our pipeline of commercial opportunities, valued at over $500 million, reflects the global demand for proven clean heat solutions. As industries move to decarbonize and reduce their reliance on fossil fuels, our technology is meeting that need head-on with performance, reliability, and scalability. In an environment where many companies are still conceptual, Brenmiller is already delivering.

The market is evolving—and we are leading that evolution with a bold step forward.

We believe that our current corporate structure, designed to expand our reach and unlock new sources of private capital, will help accelerate our timeline to positive cash flow. Under this structure, our parent company retains full ownership of our proprietary technology while licensing it to newly formed European subsidiaries. These subsidiaries are open to direct private investment, enabling them to rapidly scale localized operations and convert our pipeline into revenues—without diluting our public shareholders.

We operate under this corporate structure to strengthen our foundation and multiply our opportunities:

• It opens access to substantial private capital—without equity dilution
• It generates near-term and recurring licensing revenues
• It shifts operating costs to subsidiaries, optimizing our financial profile
• It positions the value of our subsidiaries to enhance Brenmiller's public market valuation
• And it accelerates our path to positive cash flow

This structure also aligns with our Technology Roadmap 2030, which lays out a clear plan to launch new systems every 12 to 18 months, ensuring we maintain our competitive edge and continue setting the pace for the global TES sector.

We offer a practical, high-impact solution to one of our time's most critical energy problems: how to decarbonize heat while stabilizing the grid. Our systems reduce industrial emissions, stabilize energy costs, and integrate seamlessly with renewables—all without depending on subsidies or regulatory incentives. That resilience is key for creating value for our customers and why we believe the best is still ahead.

We are fortunate to have the clarity, collaborations, and technological edge to move decisively—and to do so from a position of strength. The future of energy is being written now, and Brenmiller is one of the companies writing it.

Thank you for your continued trust and support. We're building something enduring, and together, we're unlocking its full potential.

With gratitude,

Avi Brenmiller

Chairman & Chief Executive Officer
