11 Appendix A – Key Performance Metrics • “Annual Recurring Revenue” or “ARR”, is the annualized revenue from SaaS and related revenue of our software products. We calculate ARR by annualizing the monthly recurring revenue for all active sites as of the last day of each month for the respective reporting period. ARR also includes recurring payment processing services revenue, net of expenses. We charge a per-transaction fee each time a customer payment is processed electronically. • “Contracted ARR” is ARR that also includes signed/booked sites that have yet to be activated • “Bookings” is a customer purchase order for SaaS; upon PAR’s acceptance the customer is obligated to purchase the SaaS and pay PAR for the services. In specific cases with our Punchh, bookings are added at the time of execution of the relevant master services agreement. • “Activations” are calculated as of the end of each month based on the number of SaaS customers that have initiated use of our software products/platforms. Once “activated” PAR begins to invoice/bill the customer. In specific cases with Punchh, invoicing begins before activation takes place. • “Active Sites” represent locations active on PAR’s SaaS software as of the last day of the respective fiscal period. • “Churn” reflects the negative change in SaaS subscription levels of PAR customers, calculated by dollars. For a specific period. Key Performance Indicators and Strategic Financial Metrics We monitor certain operating and non-GAAP financial metrics in the evaluation and management of our business: certain key operating and non-GAAP financial metrics have been provided as we believe these to be useful in facilitating period-to-period comparisons of our business performance. Operating and non-GAAP financial metrics do not reflect and should be viewed independently of our financial performance determined in accordance with GAAP. Operating and non-GAAP financial metrics are not forecasts or indicator of future or expected results and should not have undue reliance placed upon them by investors.
