Firefly Aerospace Inc. reported an insider ownership change for Kevin G. McAllister tied to a June 4, 2026 equity award involving the company’s common stock. The Form 4 indicates that McAllister received restricted stock units, or RSUs, under the Firefly Aerospace Inc. 2025 Omnibus Incentive Plan. Each RSU represents a contingent right to receive one share of Firefly common stock. The award is scheduled to vest on June 4, 2027, provided McAllister continues serving the company through that vesting date. The filing’s explanatory notes state that a portion of McAllister’s beneficially owned securities consists of RSUs. However, the provided filing text does not include the transaction table showing the number of RSUs granted, the transaction code, the grant price, or McAllister’s total beneficial ownership following the transaction. As a result, the filing confirms the nature and vesting terms of the award but does not provide enough detail in the supplied text to quantify the size of the grant or post-transaction holdings. The report was signed on June 8, 2026, by David Wheeler as attorney-in-fact for the reporting person.
