Management Comments

• Michelle turns relationships into results. She secured the state support behind our factory, built the team that staffs it, and opened the federal channel that led to our Department of War partnership. I also want to thank Nathan Kroeker, who strengthened our balance sheet when it mattered most and hands over a commercial organization built to deliver. Joe Mastrangelo, CEO
• Eos sits where energy security, domestic manufacturing, and grid demand meet. Utilities and data center developers are asking for storage they can site and service in the United States, and federal policy is pointed the same way. My job is converting that into orders, revenue, and customer relationships that last. We have the technology, the factory, and the team. The work ahead is execution. Michelle Buczkowski, CCO
• It has been a privilege to be part of Eos as we've positioned the Company to capture the market opportunity, and deliver on its growth plans. I am proud of what this team has built and confident in where it is going. Eos has the foundation, the customers, and the leadership to execute on what is ahead. I have had the pleasure of working alongside Michelle for the past 2 years and Im confident that she is the right person to lead the Commercial organization going forward. Nathan Kroeker

Industry Context

The consolidation of commercial functions reflects a strategic move to capitalize on these market tailwinds.

Key Dates

Recommendation

The filing details a leadership transition in a key commercial role, which is a neutral event in isolation. While the new appointee has a strong background and the consolidation of functions is strategically sound, there are no new financial results or significant strategic shifts presented that would warrant a buy or sell recommendation at this time. The focus remains on execution.
