Brenmiller Energy CEO Avi Brenmiller Issues Year-End Letter to Shareholders

Solid foundation for focused growth in 2026

103 MWh in cumulative projects deployed and a multimillion dollar pipeline of commercial opportunities

Smart capital moving into TES industry

ROSH HA'AYIN, ISRAEL / ACCESS Newswire / December 22, 2025 / Brenmiller Energy Ltd. ("Brenmiller", "Brenmiller Energy" or the "Company") (Nasdaq:BNRG), a leading global provider of Thermal Energy Storage ("TES") solutions for industrial and utility customers, today issued a letter from its Chief Executive Officer, Avi Brenmiller.

To Our Valued Shareholders,

As we close out 2025, I want to speak candidly about where Brenmiller Energy stands today, what we've accomplished, where we've fallen short, and how we are positioning the Company for a stronger 2026.

First and foremost, we recognize the decline in our share price over the past year. We understand the frustration this creates, and we take responsibility for it. The disconnect between the long-term value we believe we are building and the Company's current market valuation is not lost on us. Both our management and our Board of Directors are aligned with our shareholders and committed to acting decisively. With a significant portion of our compensation being equity-based, our management team's success is directly tied to restoring and growing shareholder value.

Accountability, Alignment, and Strategic Adjustment

In response, we are actively evaluating adjustments to our strategy and operational focus, which we believe can drive clearer, faster results. This includes sharpening execution, prioritizing near-term revenue catalysts, and potentially expanding into highly synergistic, energy-related activities that we believe can accelerate scale, improve cash generation, and better reflect the full value of our technology platform.

I also want to emphasize that this team is no stranger to navigating complex and difficult market environments. Over the past 30 years, before founding Brenmiller Energy, members of our management team repeatedly faced periods of challenge, and we were able to recover through discipline, adaptability, and hard work. In my previous company, working with many of the same core team members, we made a fundamental strategic shift from being an equipment supplier to becoming an energy company, and from being a technology provider to a project developer. That transformation took time and persistence, but it ultimately led to building a global business that was sold to Siemens for nearly $500 million. We are confident in our ability to execute a similar evolution here.

2025: A Year of Foundations and Validation

Despite some headwinds, 2025 was a year of meaningful progress and validation for Brenmiller Energy.

We signed a landmark Systems Purchase Agreement with Baran Energy Ltd. covering two bGen ZERO TES systems for Tempo Beverages Ltd. ("Tempo") and Wolfson Medical Center in Israel. This agreement represents a major inflection point for the Company, providing milestone-based payments, profit sharing, and long-term service revenues, while accelerating deployment of two flagship projects.

We now have 103 MWh of cumulative projects deployed, with numerous additional systems in development and a multimillion dollar global pipeline of commercial opportunities spanning multiple industries and regions. When we reported our first-half 2025 results, we projected approximately $1.7 million in revenue during 2026, driven primarily by bGen ZERO execution milestones tied to the Tempo project.

The European Commission's €1 billion Innovation Fund (the "Innovation Fund") has zeroed in on decarbonizing industrial heat, and we believe that we are positioned right at that intersection. Add to that our non-binding memorandum of understanding with ENASCO Ltd. to integrate bGen systems with small modular reactors, and we believe that the future looks even stronger. We believe the small modular reactor segment is shaping up to be one of the most transformative areas in clean energy, and we believe that our TES technology could be a natural fit for it.

Recognition of our technology continued to grow. During the year, bGen ZERO received the Gold Award at the 2025 Edison Awards in the Energy Storage and Management category, one of the most prestigious honors for innovation and commercial impact. We also were honored to receive POWER Magazine's 2025 Commercial & Industrial Generation Award for our bGen ZERO deployment at the State University of New York's Purchase campus.

Brenmiller Energy at the Forefront of Technology as Smart Money Moves into TES

At Brenmiller Energy, we aim to be in front of the curve in delivering a TES system that works, just as major corporations around the world are looking to deploy TES systems to cut carbon emissions, lower energy costs, and secure reliable heat supply. Smart capital is moving quickly.

Breakthrough Energy Ventures, founded by Bill Gates, has invested in leading TES innovators such as Antora Energy and Fourth Power. Institutional investors like BlackRock and Temasek have also invested in the TES sector, underscoring the category's momentum. The category is now attracting some of the world's most influential climate and infrastructure investors, and Brenmiller is among the publicly traded companies focused entirely on this transformative technology.

Building Global Collaborations

In 2025 we also made important strides in expanding Brenmiller's global footprint:

• We signed a non-binding memorandum of understanding in Japan with a prominent engineering and project development company to jointly identify and deploy sustainable heating solutions across the Japanese market.

• In Europe, two projects are estimated to receive approximately €11 million in funding tied to bGen deployments. In Spain, the SolWinHy Cádiz project is expected to include a bGen system valued at approximately €7 million, with execution anticipated to begin in 2026. In a separate European project led by a top utility company, Brenmiller Europe S.L. ("Brenmiller Europe"), is expected to supply a 5 MWe bGen system supported by Innovation Fund funding, which would deliver significant emissions reductions and efficiency gains.

• We believe additional projects in our European pipeline may qualify for future Innovation Fund rounds, reinforcing our confidence in the region's long-term growth potential.

Key Milestones Ahead in 2026

• The Tempo project is nearing completion and commissioning, which we view as a major milestone and a critical sales enabler, serving as a reference site for global industrial customers.

• Wolfson Medical Center is expected to begin construction soon, with project completion targeted by the end of 2026.

• The European Commission is launching a €1 billion Innovation Fund auction focused on decarbonizing industrial heat-an area directly aligned with our technology and pipeline.

• Our Systems Purchase Agreement with Baran Energy is expected to generate milestone payments, profit sharing, and recurring service revenues as projects advance.

• We have a private placement agreement for up to $25 million, providing a long-term institutional shareholder the right to provide us further financial resources to support execution and growth.

Looking Forward

As I see it, Brenmiller Energy is at a pivotal moment. We believe that the industrial energy landscape is shifting from "could we" to "now we must." Industrial customers, policymakers, and capital providers are increasingly recognizing that decarbonizing heat, not just electricity, is essential.

We are adjusting, we are focused, and we are committed. The foundation we have built is real. Our technology performs. The market opportunity is large and accelerating. And while challenges remain, we firmly believe that with disciplined execution, strategic flexibility, and the dedication of our team, we can convert this potential into tangible shareholder value.

On behalf of our Board of Directors and management, thank you for your continued support and patience. We do not take your trust lightly. We wish you all a prosperous 2026.

Sincerely,

Avi Brenmiller
Chief Executive Officer, Brenmiller Energy Ltd.
