14partech.com Investment Thesis 1. Foodservice market ready for disruption • Large TAM in restaurants with ~1m locations in the US spending 2-3% of total revenue on technology (1) • Enterprise foodservice playing “catch-up” in adopting new technology and anticipate this technology spend to ramp • The industry shift to cloud technology has led to an explosion in new technology from Voice AI to marketing technology 2. Meeting market need with a Unified Experience • Today technology is driving a wedge between restaurants and their guests • Brands are shifting to well integrated vendors and more targeted guest interactions • There is an opportunity to create an integrated solution with unified data that enables restaurants to have 1:1 relationship with their guests • Industry seeking vendor consolidation and platform experience and reduce single-product providers 3. ARR at scale with strong SaaS metrics • Through both organic and inorganic strategies, ARR has reached $298.4 million with significant opportunity to expand within existing customers and win new business • Hyper-focus on stringent OpEx spend management with real ROI mindset 1.

15partech.com Key Performance Indicators • 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 recurring 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. Applying a constant currency impacted our reported ARR figures for Q3 2024 and Q4 2024 as exchange rate effects began with the acquisition of TASK Group Holdings Limited in July 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 (loss) income before income taxes, interest expense, and depreciation and amortization adjusted to exclude discontinued operations, stock-based compensation, contingent consideration, transaction costs, severance, litigation expense, loss on extinguishment of debt, and other income (expense), net. • “ARR Per Unit” represents ARR divided by Active Sites as of the last day of each month for the respective reporting period.
