The Amendment is expected to close on or around May 15, 2026, subject to customary closing conditions.

The Amendment would extend the maturity of the Term Credit Facility to six years following the closing date of the Amendment, and reduce the rate of interest on borrowings to, at the Company's election, to either (i) term SOFR plus 300 bps or (ii) base rate plus 200 bps. The principal amount of the Term Credit Facility after giving effect to the Amendment and contemplated prepayments to be made contemporaneously with the consummation of the Amendment will be $850.0 million.
