Additional 402(v) Disclosure        
In accordance with the SEC’s disclosure requirements regarding pay versus performance, or PVP, this section presents the SEC-defined “Compensation Actually Paid,” or CAP. Also required by the SEC, this section compares CAP to various measures used to gauge our performance. CAP is a supplemental measure to be viewed alongside performance measures as an addition to the philosophy and strategy of compensation-setting discussed elsewhere in the overview of the executive compensation program, not in replacement.
The graphs below compare the compensation actually paid to our PEOs and the average of the compensation actually paid to our remaining named executive officers, with (i) our cumulative TSR, and (ii) our net income, in each case, for the fiscal years ended December 31, 2025, 2024 and 2023. TSR amounts reported in the graph assume an initial fixed investment of $100.
