Forward Looking Statements & Other Information The statements contained in this report that are not purely historical are forward-looking statements, including statements regarding expectations, hopes, intentions or strategies regarding the future. Forward- looking statements are based on Dun & Bradstreet’s management’s beliefs, as well as assumptions made by, and information currently available to, them. Forward-looking statements can be identified by words such as "anticipates," "intends," "plans," "seeks," "believes," "estimates," "expects" and similar references to future periods, or by the inclusion of forecasts or projections. Examples of forward-looking statements include, but are not limited to, statements we make regarding the outlook for our future business and financial performance, such as those contained in "Management’s Discussion and Analysis of Financial Condition and Results of Operations" ("MD&A"). Because such statements are based on expectations as to future financial and operating results and are not statements of fact, actual results may differ materially from those projected. It is not possible to predict or identify all risk factors. Consequently, the risks and uncertainties listed below should not be considered a complete discussion of all of our potential trends, risks and uncertainties. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise. The risks and uncertainties that forward-looking statements are subject to include, but are not limited to: (i) our ability to implement and execute our strategic plans to transform the business; (ii) our ability to develop or sell solutions in a timely manner or maintain client relationships; (iii) competition for our solutions; (iv) harm to our brand and reputation; (v) unfavorable global economic conditions including, but not limited to, volatility in interest rates, foreign currency markets, inflation and supply chain disruptions; (vi) risks associated with operating and expanding internationally; (vii) failure to prevent cybersecurity incidents or the perception that confidential information is not secure; (viii) failure in the integrity of our data or systems; (ix) system failures and personnel disruptions, which could delay the delivery of our solutions to our clients; (x) loss of access to data sources or ability to transfer data across the data sources in markets where we operate; (xi) failure of our software vendors and network and cloud providers to perform as expected or if our relationship is terminated; (xii) loss or diminution of one or more of our key clients, business partners or government contracts; (xiii) dependence on strategic alliances, joint ventures and acquisitions to grow our business; (xiv) our ability to protect our intellectual property adequately or cost-effectively; (xv) claims for intellectual property infringement; (xvi) interruptions, delays or outages to subscription or payment processing platforms; (xvii) risks related to acquiring and integrating businesses and divestitures of existing businesses; (xviii) our ability to retain members of the senior leadership team and attract and retain skilled employees; (xix) compliance with governmental laws and regulations; (xx) risks related to the voting letter agreement among and registration and other rights held by certain of our largest shareholders; (xxi) an outbreak of disease, global or localized health pandemic or epidemic, or the fear of such an event (such as the COVID-19 global pandemic), including the global economic uncertainty and measures taken in response; (xxii) the short- and long-term effects of the COVID-19 global pandemic, including the pace of recovery or any future resurgence; (xxiii) increased economic uncertainty related to the ongoing conflict between Russia and Ukraine and associated trends in macroeconomic conditions, and (xxiv) the other factors described under the headings “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and elsewhere in our consolidated financial statements for the year ended December 31, 2021, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 24, 2022, our other Quarterly Reports and the Company’s other reports or documents filed with the SEC. The following discussion and analysis of Dun & Bradstreet Holdings, Inc.’s financial condition and results of operations is provided as a supplement to the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2022, and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021, our “Risk Factors,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 24, 2022. References in this discussion and analysis to “the Company,” “Dun & Bradstreet,” “D&B,” “we,” “us” and “our” refer to Dun & Bradstreet Holdings, Inc. and its subsidiaries. The Presentation also includes certain financial information that is not presented in accordance with Generally Accepted Accounting Principles (“GAAP”), including, but not limited to, Adjusted Revenue, Organic Revenue, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, and certain ratios and other metrics derived therefrom. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing the Company’s financial results. Further, it is important to note that non-GAAP financial measures should not be considered in isolation and may be considered in addition to GAAP financial information but should not be used as substitutes for the corresponding GAAP measures. It is also important to note that EBITDA, Adjusted EBITDA for specified fiscal periods have been calculated in accordance with the definitions thereof as set out in our public disclosures and are not projections of anticipated results but rather reflect permitted adjustments. Additionally, this Presentation contains forward-looking financial measures presented on a non-GAAP basis without reconciliation to the most directly comparable GAAP measure due to the inherent difficulty, without unreasonable efforts, in forecasting and quantifying with reasonable accuracy significant items required for this reconciliation. You should be aware that Dun & Bradstreet’s presentation of these and other non-GAAP financial measures in this Presentation may not be comparable to similarly-titled measures used by other companies.

58 Non-GAAP Financial Measures: In addition to reporting GAAP results, we evaluate performance and report our results on the non-GAAP financial measures discussed below. We believe that the presentation of these non-GAAP measures provides useful information to investors and rating agencies regarding our results, operating trends and performance between periods. These non-GAAP financial measures include adjusted revenue, organic revenue, adjusted earnings before interest, taxes, depreciation and amortization ("adjusted EBITDA"), adjusted EBITDA margin, adjusted net income and adjusted net earnings per diluted share. Adjusted results are non-GAAP measures that adjust for the impact due to certain acquisition and divestiture related revenue and expenses, such as costs for banker fees, legal fees, due diligence, retention payments and contingent consideration adjustments, restructuring charges, equity-based compensation, and other non-core gains and charges that are not in the normal course of our business, such as costs associated with early debt redemptions, gains and losses on sales of businesses, impairment charges, the effect of significant changes in tax laws and material tax and legal settlements. We exclude amortization of recognized intangible assets resulting from the application of purchase accounting because it is non-cash and not indicative of our ongoing and underlying operating performance. Recognized intangible assets arise from acquisitions, primarily the Take-Private Transaction. We believe that recognized intangible assets by their nature are fundamentally different from other depreciating assets that are replaced on a predictable operating cycle. Unlike other depreciating assets, such as developed and purchased software licenses or property and equipment, there is no replacement cost once these recognized intangible assets expire and the assets are not replaced. Additionally, our costs to operate, maintain and extend the life of acquired intangible assets and purchased intellectual property are reflected in our operating costs as personnel, data fee, facilities, overhead and similar items. Management believes it is important for investors to understand that such intangible assets were recorded as part of purchase accounting and contribute to revenue generation. Amortization of recognized intangible assets will recur in future periods until such assets have been fully amortized. In addition, we isolate the effects of changes in foreign exchange rates on our revenue growth because we believe it is useful for investors to be able to compare revenue from one period to another, both after and before the effects of foreign exchange rate changes. The change in revenue performance attributable to foreign currency rates is determined by converting both our prior and current periods’ foreign currency revenue by a constant rate. As a result, we monitor our adjusted revenue growth both after and before the effects of foreign exchange rate changes. We believe that these supplemental non-GAAP financial measures provide management and other users with additional meaningful financial information that should be considered when assessing our ongoing performance and comparability of our operating results from period to period. Our management regularly uses our supplemental non-GAAP financial measures internally to understand, manage and evaluate our business and make operating decisions. These non-GAAP measures are among the factors management uses in planning for and forecasting future periods. Non- GAAP financial measures should be viewed in addition to, and not as an alternative to our reported results prepared in accordance with GAAP. Our non-GAAP or adjusted financial measures reflect adjustments based on the following items, as well as the related income tax. Adjusted Revenue We define adjusted revenue as revenue to include a revenue adjustment due to the timing of the completion of the Bisnode acquisition in 2021 and deferred revenue purchase accounting adjustments 2019, 2020 and 2021. Management uses this measure to evaluate ongoing performance of the business period over period. In addition, we isolate the effects of changes in foreign exchange rates on our revenue growth because we believe it is useful for investors to be able to compare revenue from one period to another, both after and before the effects of foreign exchange rate changes. The change in revenue performance attributable to foreign currency rates is determined by converting both our prior and current periods’ foreign currency revenue by a constant rate. Organic Revenue We define organic revenue as adjusted revenue before the effect of foreign exchange excluding revenue from acquired businesses for the first twelve months. In addition, organic revenue excludes current and prior year revenue associated with divested businesses. We believe the organic measure provides investors and analysts with useful supplemental information regarding the Company’s underlying revenue trends by excluding the impact of acquisitions and divestitures. Adjusted EBITDA and Adjusted EBITDA Margin We define adjusted EBITDA as net income (loss) attributable to Dun & Bradstreet Holdings, Inc. excluding the following items: • depreciation and amortization; • interest expense and income; • income tax benefit or provision; • other non-operating expenses or income; • equity in net income of affiliates; • net income attributable to non-controlling interests; • purchase accounting deferred revenue adjustments; • dividends allocated to preferred stockholders; • equity-based compensation; • restructuring charges; • merger, acquisition and divestiture-related operating costs; • transition costs primarily consisting of non-recurring expenses associated with transformational and integration activities, as well as incentive expenses associated with our synergy programs; and • other adjustments primarily related to non-cash charges and gains, including impairment charges and adjustments as the result of the application of purchase accounting mainly related to the deferred commission cost amortization associated with the Take-Private Transaction and revenue adjustment associated with the Bisnode acquisition. In addition, other adjustments also include non-recurring charges such as legal expense associated with significant legal and regulatory matters. We calculate adjusted EBITDA margin by dividing adjusted EBITDA by adjusted revenue.
