2026 Incentive Plan financial

"under the Corporation's 2026 Incentive Plan pursuant to the Corporation's Amended and Restated Director Compensation Policy"

A 2026 incentive plan is a company’s formal program, often named for a year, that authorizes awards like stock options, restricted shares, and cash bonuses to employees and executives to motivate performance and retain talent. For investors it matters because the plan creates potential new shares or payouts that can dilute existing ownership and align management’s choices with company goals—think of it as a reward budget that affects both pay incentives and share value.
