Omnibus Incentive Plan financial

"These awards were granted pursuant to the Company's 2024 Omnibus Incentive Plan."

An omnibus incentive plan is a single, flexible program a company uses to give employees and executives different types of pay tied to performance — for example stock options, restricted shares, cash bonuses and other awards — all governed by one set of rules. It matters to investors because it determines how many new shares may be created, how leaders are motivated and how much the company will spend on compensation over time; think of it as a master toolbox that affects both costs and the total share supply.
