DISCLAIMER (CONT’D) Non-GAAP Financial Measures. This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles in the U.S. (“GAAP”), including, but not limited to, Adjusted Revenue, Adjusted Gross Profit and Adjusted EBITDA, in each case presented on a non-GAAPbasis. These non-GAAP financial measures of financial performance may exclude items that are significant in understanding and assessing the Company’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to revenue, gross profit or net income or other measures of profitability, liquidity or performance under GAAP. You should be aware that the Company’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in comparing the Company’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Please refer to the non-GAAP reconciliation provided in this Presentation for a reconciliation of these measures to what the Company believes are the most directly comparable measures evaluated in accordance with GAAP.

The calculation includes changes for these billing accounts, such as change in the solutions purchased, changes in pricing and transaction volume, but does not reflect revenue for new customers added. The calculation excludes: (a)changes in estimates related to the timing ofone-timerevenue and other revenue, including professional services, and (b) annualized software revenue for smaller customers with annualized software revenue below the threshold of $100,000 for carriers and $4,000 for shops. We calculate Software Gross Dollar Retention Rate (“Software GDR”) by dividing (a)annualized software revenue recorded in the last month of the measurement period in the prior year, reduced by annualized software revenue for unique billing accounts that are no longer customers as of the current period end by (b) annualized software revenue as of the corresponding month of the prior year. The calculation excludes: (a)changes in estimates related to the timing ofone-timerevenue and other revenue, including professional services, and (b)annualized software revenue for smaller customers with annualized software revenue below the threshold of $100,000 for carriers and $4,000 for shops. © CCC Information Services Inc.
