(1)	Restricted stock units granted under the Issuer's 2026 Omnibus Incentive Plan represent a contingent right to receive the Issuer's common stock on a one-for-one basis when the restricted stock units vest.

The Performance Restricted Stock Units vest between 0% and 250% of target, measured as of the earlier of the final financial quarter of the Performance Period or during a measurement period ending no fewer than three days prior to a Change in Control of the Issuer.
