Footnotes from the filing
RSUs convert into the Company's common stock on a one-for-one basis.
Represents the vesting of performance-adjusted RSUs, each of which previously represented a contingent right to receive an RSU award payable 2/3 in shares of common stock of the Company ("Share-Based RSUs") and 1/3 in cash ("Cash-Based RSUs") following the vesting date. The satisfaction of the performance goals for the RSUs were certified by the Company's Board of Directors on February 11, 2026, as previously reported on a Form 4 filed on February 13, 2026, and the RSUs, which had remained subject to a continued service requirement, vested on March 1, 2026.
