Insider trading arrangements

Due to the Company’s change in fiscal year end, certain previously granted equity awards are now scheduled to vest during a period in which the Company’s insider trading policy restricts trading for certain individuals. This timing misalignment is expected to recur until all outstanding awards granted under the Company’s former fiscal year reporting cycle have vested. To facilitate the sale of shares to be received upon the vesting of such awards, the following officers adopted Rule 10b5-1 trading arrangements 1, as defined in Item 408(a) of Regulation S-K (“Plan”), during the quarter ended June 30, 2026:

(1)During the quarter, no director or officer (i) terminated a Plan or (ii)adopted orterminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).

(2)The Plans provide for the sale of a specified percentage of shares to be received upon future vesting of certain outstanding equity awards, net of any shares withheld by the Company to satisfy applicable taxes. The actual number of shares to be sold pursuant to each Plan may vary and will depend upon, as applicable, the vesting of performance-based awards, future dividend equivalent accruals with respect to awards that include dividend equivalent rights, as well as the number of shares withheld for tax purposes. For purposes of this disclosure, any shares underlying performance-based equity awards were calculated at target and the total number of shares underlying any equity awards with dividend equivalent rights include the dividend equivalents accrued as of the date of each Plan.

(3)Each Plan expires on the date shown above, subject to earlier termination as provided in each Plan.
