partech.com • Annual Recurring Revenue or "ARR” is the annualized revenue from subscription services, including subscription fees for our SaaS solutions and related software support, managed platform development services, and transaction-based payment processing services. We generally calculate ARR by annualizing the monthly subscription service revenue for all Active Sites as of the last day of each month for the respective reporting period. Our reported ARR is based on a constant currency, using the exchange rates established at the beginning of the year and consistently applied throughout the period and to comparative periods presented. For acquisitions made during each period, the constant currency rate applied is the exchange rate at the date of each acquisition's closure. There was no impact on our prior period ARR as a result of applying a constant currency as the exchange rate effects only began with the TASK Group Acquisition in 2024. • “Active Sites” represent locations active on PAR’s subscription services as of the last day of the respective reporting period. • “Non-GAAP Subscription Service Gross Margin Percentage” represents subscription service gross margin percentage adjusted to exclude amortization from acquired and internally developed software, stock-based compensation, and severance. • “Non-GAAP Consolidated Gross Margin Percentage” represents consolidated gross margin percentage adjusted to exclude amortization from acquired and internally developed software, stock-based compensation, and severance. • “Adjusted EBITDA” represents net income (loss) before income taxes, interest expense and depreciation and amortization adjusted to exclude certain non-cash and non-recurring charges that may not be indicative of our financial performance Key Performance Indicators 19
