Additional 402(v) Disclosure
Equity values are calculated in accordance with FASB ASC Topic 718.
In fiscal 2025, the Company suspended its annual cash incentive plan and so our NEOs compensation consisted of base salary, time-based restricted stock units (RSUs), and performance-based restricted stock units (PSUs). As a result, in fiscal 2025, the key performance measures linking 8x8’s performance to compensation actually paid were Relative Total Stockholder Return (TSR) and non-indexed stock price performance for PSUs granted prior to fiscal 2025 and Cumulative Cash Flow From Operations (CFFO) for PSUs granted in fiscal 2025. Even as total compensation for our NEOs dropped in fiscal 2025 due to suspension of the annual cash incentive plan, the charts below illustrate how our compensation programs continue to be designed to maintain strong links between the performance of the Company, the returns earned by our stockholders, and the compensation that is paid to our executives. While 8x8 has delivered strengthened financial performance as measured through cash flow from operations and continued improvements in net income, the positive impact these achievements have had on compensation have been significantly overshadowed by the impact of the negative stockholder returns over this same period in both absolute and relative measurements. This has resulted in either significantly lower, or negative, compensation actually paid to executives for fiscal 2022 - 2025.
