Summary

Eos Energy Enterprises formalized an employment agreement with Michelle Buczkowski, its Chief Administration Officer, on March 30, 2026. The agreement supersedes her previous offer letter and establishes a compensation package of $385,000 annual base salary plus a target bonus of 75% of base salary, with actual payout tied to performance metrics. Ms. Buczkowski is also eligible for annual long-term incentive grants.

For retail investors, this is a routine executive compensation disclosure with limited immediate impact. The agreement includes standard severance protections that could create future obligations if Ms. Buczkowski's employment ends involuntarily, including 12 months of salary continuation and accelerated equity vesting.

The total compensation package appears consistent with C-suite roles at companies of similar size in the energy storage sector. Investors should monitor whether this signals broader executive team stability or restructuring at Eos Energy, particularly given the company's ongoing efforts to scale its zinc-based battery technology. Watch for any subsequent executive changes or organizational announcements in coming quarters.

if Ms. Buczkowski’s employment is involuntarily terminated (i.e., terminated without Cause (as defined in the Employment Agreement) or with Good Reason (as defined in the Employment Agreement)), conditioned on Ms. Buczkowski’s execution and non-revocation of a release of claims, Ms. Buczkowski will be entitled to receive: any accrued but unpaid base salary and vacation earned through the date of termination, any earned but unpaid annual bonus in respect of any calendar year preceding the termination of employment, twelve (12) months of continued base salary, prorated annual bonus based on actual performance if Ms. Buczkowski has completed three full months of service of the applicable calendar year, prior to the termination of employment, and the vesting of outstanding equity awards that would have vested over the twelve month period immediately following Ms. Buczkowski’s date of termination (subject to the attainment of any applicable performance goals).

If Ms. Buczkowski is terminated without cause or resigns for good reason, she receives twelve months of base salary continuation, a prorated bonus if she worked at least three months of the year, and accelerated vesting of equity awards that would have vested in the following twelve months. This severance package represents potential future obligations for the company.
