restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted under the Firefly Aerospace Inc. 2025 Omnibus Incentive Plan."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

2025 Omnibus Incentive Plan financial

"RSUs granted under the Firefly Aerospace Inc. 2025 Omnibus Incentive Plan."

An omnibus incentive plan is a company-wide program that authorizes awards of pay tied to performance and retention—such as stock options, restricted shares, cash bonuses and other rewards—here labeled for the year it was adopted (2025). Investors care because it affects how much ownership can be issued, dilutes existing shareholders, and aligns executives’ and employees’ incentives with company goals, similar to giving team members a stake in the outcome.

"Each RSU represents a contingent right to receive one share of the Issuer's common stock."
