Subsequent events may cause these expectations to change, and PROS disclaims any obligations to update or alter these forward-looking statements in the future, whether as a result of new information, future events or otherwise. This presentation includes certain supplemental non-GAAP financial measures, that we believe are useful to investors as tools for assessing the comparability between periods as well as company by company. Our computation of these measures may not be comparable to other similarly titled measures computed by other companies. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, our financial information and results prepared in accordance with U.S. GAAP included in our periodic filings made with the SEC. Investors are encouraged to review the reconciliation of our historical non-GAAP financial measures to the comparable GAAP results, which can be found, along with other financial information, on the investor relations’ page of our website at PROS.com. We are unable to reconcile forward-looking non-GAAP financial measures to their directly comparable GAAP financial measures because the information needed to complete a reconciliation is unavailable at this time without unreasonable effort.

Business Overview 4

© 2025 PROS, Inc. All rights reserved. Confidential and Proprietary. Businesses Face Many Challenges Today 6 Business uncertainty is here to stay. Everything is in a constant state of rapid change – costs, currencies, supply chains, prices, demand patterns – and in response, businesses must constantly change what they sell, how they sell, and how they price. Customers have increasingly higher expectations. Buyers expect every buying experience to be as magical as the best one they have ever had (“the Amazon effect”). Self-serve, tailored experience, transparency, and accuracy driven by convenience, value, and confidence across all touchpoints. The way we work is evolving. Manual business processes and disconnected digital tools cause more time to be spent on process than on driving business forward. Digitization, automation, and AI are critical for keeping up and driving a better employee experience.

Appendix 33

© 2025 PROS, Inc. All rights reserved. Confidential and Proprietary. Supplemental Information – Explanation of Non-GAAP Measures 34 PROS has provided certain financial information that has not been prepared in accordance with GAAP. This information includes non-GAAP gross profit, non-GAAP gross margin, non-GAAP subscription gross margin, non-GAAP recurring revenue gross margin, adjusted EBITDA and free cash flow. PROS uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating PROS ongoing operational performance. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure. A reconciliation of GAAP to the non-GAAP financial measures has been provided in these tables and in the earnings press release. PROS use of non-GAAP financial measures may not be consistent with the presentations by similar companies in PROS industry. Non-GAAP gross profit: Non-GAAP gross profit is defined as GAAP gross profit less amortization of acquisition-related intangibles, severance and share-based compensation costs allocated to cost of subscription, maintenance and support, and services. Non-GAAP gross margin is calculated as the percentage of non-GAAP gross profit divided by total revenue. Non-GAAP subscription gross margin and recurring revenue gross margin are similarly calculated to compare the non-GAAP gross profit of subscription revenue and recurring revenue (subscription, maintenance and support revenue), respectively, to total subscription and recurring revenue, respectively. In calculating the non-GAAP gross profit of subscription revenue, the total costs of subscription are adjusted to reduce such costs by the portion of amortization of acquisition-related intangibles, severance and share-based compensation costs allocated to cost of subscription. In calculating the non-GAAP gross profit of recurring revenue, the total costs of subscription, maintenance and support are adjusted to reduce such costs by the portion of amortization of acquisition-related intangibles, severance and share-based compensation costs allocated to cost of subscription and cost of maintenance and support. Adjusted EBITDA: Adjusted EBITDA is defined as GAAP net income (loss) before interest expense, provision for income taxes, depreciation and amortization, as adjusted to eliminate the effect of stock-based compensation cost, severance, amortization of acquisition-related intangibles, depreciation and amortization, and capitalized internal-use software development costs. Adjusted EBITDA should not be considered as an alternative to net loss as an indicator of our operating performance. Free Cash Flow: Free cash flow is a non-GAAP financial measure which is defined as net cash provided by (used in) operating activities, excluding severance payments, less capital expenditures and capitalized internal-use software development costs. Calculated Billings: Calculated billings is defined as total subscription, maintenance and support revenue plus the change in recurring deferred revenue in a given period.
