Fluence Energy, Inc. reported an insider ownership change for Peter Bennett Williams involving the company’s Class A common stock on July 17, 2026. The Form 4, filed July 21, 2026, reflects activity tied to the vesting of restricted stock units, or RSUs, previously granted to Williams. The filing reports 26,197 shares of Fluence Class A common stock associated with the RSU vesting, with the shares referenced at $14.07 per share. Each RSU represented a contingent right to receive one share of Class A common stock. According to the explanatory note, the RSUs vested in three equal annual installments: the first on July 17, 2024, the second on July 17, 2025, and the final installment on July 17, 2026. The reported transaction therefore corresponds to the final vesting tranche of that award. In connection with the vesting, Fluence withheld 3,905 shares of Class A common stock, also valued at $14.07 per share, to satisfy Williams’s tax withholding obligations. This type of share withholding is a common administrative transaction when equity awards vest; it reduces the number of shares delivered to the insider but does not necessarily indicate an open-market sale. After the tax withholding, the net number of shares retained from this vesting event was 22,292 shares, before considering any other Fluence holdings Williams may have. The provided filing text does not state Williams’s total beneficial ownership after the transaction, nor does it show explicit transaction codes, though the notes identify the activity as RSU vesting and related tax withholding. The filing was signed on Williams’s behalf by Leah Patterson as attorney-in-fact on July 21, 2026.
