Settlement of Dividend Equivalent Rights (DERs) that accrued on June 2, 2026 and were settled in shares on vesting of the related RSUs on June 2, 2026. The RSUs vested on June 2, 2026. Amounts reported include DERs that accrued on the RSUs prior to June 2, 2026. The DERs accrued on four outstanding RSU awards and vest proportionately with the RSUs to which they relate. The number of DERs is calculated as of the dividend record date by multiplying the dividend per share ($1.25) by the number of outstanding RSUs, and, to the extent applicable, previously accrued DERs and then dividing the result by the fair value of the common share on the dividend payment date. Each DER is the economic equivalent of one share. /s/ Rohit Kapoor 2026-06-03
