Eos Energy CEO Joe Mastrangelo sells $980,000 in company stock

In a recent transaction on September 16, 2026, Eos Energy Enterprises' CEO Joe Mastrangelo disposed of 250,000 shares of common stock, generating a total of $980,000. The shares were sold at an average price of $3.92, with individual transactions ranging from $3.84 to $4.16. This sale was orchestrated via a pre-set Rule 10b5-1 trading plan, aimed at addressing anticipated tax withholding duties linked to the vesting of performance-based restricted stock units.

Currently priced at $1.91, the stock has plummeted 86% year-over-year, though it surged nearly 10% in the last week. Analysts suggest EOSE is undervalued at present. Ahead of this sale, on September 14, 2026, Mastrangelo purchased 500,000 shares of Eos Energy common stock at no cost, resulting from the vesting of performance-based restricted stock units (PRSUs) granted on July 5, 2024.

The vesting was triggered following the Compensation Committee's confirmation of the first performance period's success, which was tied to the company's total shareholder return targets.
