MeasureExplanation
Cash Flow From OperationsRepresents the cash generated or used by the Company's business activities and is presented as net cash provided by operating activities in our Form 10-K.
Service RevenueConsists of revenue generated from communication services subscriptions, platform usage revenue, and related fees from our UCaaS, CCaaS, and CPaaS offerings.
Non-GAAP Operating ProfitNon-GAAP Operating Profit excludes amortization of acquired intangible assets, stock-based compensation expense and related employer payroll taxes, transaction-related costs, certain legal and regulatory costs, and certain severance, transition and contract exit costs from GAAP Income from Operations. Management believes that these exclusions help capture the Company’s ongoing operating performance.
Net New Annual Subscription Revenue
Net new annual subscription revenue is an internal operating metric equal to new subscription bookings minus revenue lost to full cancellations (churn) and partial reductions (down-sells, such as tier drops or reduced seat counts).

Additional 402(v) Disclosure
Equity values are calculated in accordance with FASB ASC Topic 718.
In fiscal 2026, the Company reinstated its annual cash incentive plan. As a result, our NEOs' compensation consisted of base salary, cash incentive plan awards, time-based restricted stock units (“RSUs”), and Executive Performance Plan PSUs (“EPP PSUs”). The EPP PSUs are subject to performance conditions tied to cumulative cash flow from operations (“CFFO”) and service revenue over three annual measurement periods (fiscal years 2026, 2027, and 2028), with time-based vesting following the Board's certification of each fiscal year's performance results.
