The original filing used an estimated tax withholding amount to calculate the number of shares deliverable upon settlement; following final calculation of taxes on the exercise date, the number of shares withheld was adjusted from 2,002 shares to 2,003 shares. This amendment restates the affected line item in Table I accordingly. /s/ Matthew Rucker, as Attorney-in-Fact for Danyl R. Freeman 2026-08-12
