TIERNEY BRIAN X 4

What Happened Brian X. Tierney, Chairman, President & CEO of FirstEnergy Corp. (FE), was reported as acquiring 227,592.972 shares on February 11, 2026, as the result of a derivative award (performance-adjusted RSUs). The transaction is reported at $0.00 per share because these are restricted stock units that will convert to compensation (2/3 stock and 1/3 cash) upon vesting; the company’s board certified that the performance goals were satisfied on February 11, 2026 and the RSUs are scheduled to vest on March 1, 2026, generally subject to continued service.

Such awards reflect company compensation outcomes (performance goals satisfied) and will convert to a combination of shares and cash on vesting; they do not necessarily signal an insider buying or selling for investment reasons.
