2 Certain statements in this presentation are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, particularly those regarding our 2024 financial guidance. These forward-looking statements are based on management’s current expectations or beliefs as of November 7, 2024 (“Release Date”) and are subject to numerous assumptions, risks, and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. These factors and uncertainties include, among other items: the Company’s ability to grow advertising, licensing, and subscription revenues, profitability, and cash flows, particularly in light of an uncertain U.S. or worldwide economy, including the possibility of economic downturn or recession; the Company’s ability to make interest and debt payments; the Company’s ability to identify, close, and successfully transition acquisitions; customer growth and retention; the Company’s ability to create compelling content; our reliance on third-party platforms; the threat of content piracy and developments related to artificial intelligence; increased competition and rapid technological changes; variability of the Company’s revenue based on changing conditions in particular industries and the economy generally; protection of the Company’s proprietary technology or infringement by the Company of intellectual property of others; the risk of losing critical third-party vendors or key personnel; the risks associated with fraudulent activity, system failure, or a security breach; risks related to our ability to adhere to our internal controls and procedures; the risk of adverse changes in the U.S. or international regulatory environments, including but not limited to the imposition or increase of taxes or regulatory-related fees; the risks related to supply chain disruptions, inflationary conditions, and rising interest rates; the risk of liability for legal and other claims; and the numerous other factors set forth in the Company’s filings with the Securities and Exchange Commission (“SEC”). For a more detailed description of the risk factors and uncertainties affecting the Company, refer to our most recent Annual Report on Form 10-K and the other reports filed by the Company from time-to-time with the SEC, each of which is available at www.sec.gov. The forward-looking statements provided in this presentation, including those regarding our 2024 financial guidance, are based on limited information available to the Company as of the Release Date and are subject to change. Although management’s expectations may change after the Release Date, the Company undertakes no obligation to revise or update these statements. All information in this presentation speaks as of the Release Date and any redistribution or rebroadcast of this presentation after that date is not intended and will not be construed as updating or confirming such information. Capitalized terms not otherwise defined in this presentation have the meanings set forth in the Company’s earnings press release issued on the Release Date. Third-Party Information All third-party trademarks, including names, logos and brands, referenced by the Company in this presentation are property of their respective owners. All references to third-party trademarks are for identification purposes only and shall be considered nominative fair use under trademark law. Industry, Market and Other Data Certain information that may be contained in this presentation concerning our industry and the markets in which we operate, including our general expectations and market position, market opportunity and market size, is based on reports from various sources. Because this information involves a number of assumptions and limitations, you are cautioned not to give undue weight to such information. We have not independently verified market data and industry forecasts provided by any of these or any other third-party sources referred to in this presentation. In addition, projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause results to differ materially from those expressed in the estimates made by third parties and by us. Non-GAAP Financial information Included in this presentation are certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles ("GAAP") and are not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The non-GAAP measures, as defined by Ziff Davis, may not be comparable to similar non-GAAP measures presented by other companies, limiting their usefulness for comparison purposes. The presentation of such measures, which may include adjustments to exclude unusual or non-recurring items, should not be construed as an inference that Ziff Davis’ future results or leverage will be unaffected by other unusual or non-recurring items. Please see the "Supplemental Information" to this presentation for details related to how we define these non-GAAP measures and reconciliations thereof to the most directly comparable GAAP measures. We use these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain items that may not be indicative of our recurring core business operating results or, in certain cases, may be non-cash in nature. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance and liquidity. We believe these non- GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making, (2) certain measures are used to determine the amount of annual incentive compensation paid to our named executive officers, and (3) they are used by the analyst community to help them analyze the health of our business.

SUPPLEMENTAL INFORMATION

12 Non-GAAP Financial Measures The below non-GAAP financial measures are not measures presented in accordance with GAAP, and our use of these terms may vary from that of other companies, limiting their usefulness for comparison purposes. These non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. These non-GAAP financial measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations determined in accordance with GAAP. Non-GAAP financial measures exclude the certain items listed below. We believe that excluding these items from the non-GAAP measures facilitates comparisons to historical operating results and comparisons to peers, many of which exclude similar items. We believe that non-GAAP financial measures provide meaningful supplemental information regarding operational performance. We further believe these measures are useful to investors in that they allow for greater transparency of certain line items in the Company’s financial statements. Adjusted EBITDA is defined as Net income (loss) with adjustments to reflect the addition or elimination of certain items including, but not limited to: Interest expense, net; (Gain) loss on debt extinguishment, net; (Gain) loss on sale of business; (Gain) loss on investments, net; Other (income) loss, net; Income tax (benefit) expense; (Income) loss from equity method investments, net; Depreciation and amortization; Share-based compensation; Acquisition, integration, and other costs; Disposal related costs; Lease asset impairments and other charges; and Goodwill impairment on business. Adjusted net income (loss) is defined as Net income (loss) with adjustments to reflect the addition or elimination of certain statement of operations items including, but not limited to: Interest, net; (Gain) loss on debt extinguishment, net; (Gain) loss on sale of business; (Gain) loss on investments, net; (Income) loss from equity method investments, net; Amortization; Share-based compensation; Acquisition, integration, and other costs; Disposal related costs; Lease asset impairments and other charges; and Goodwill impairment on business. Adjusted diluted EPS is calculated by dividing Adjusted net income (loss) by the diluted weighted average shares of common stock outstanding excluding the effect of convertible debt dilution. Free cash flow is defined as Net cash provided by operating activities, less purchases of property and equipment, plus changes in contingent consideration (if any). Adjusted effective tax rate is calculated based upon the GAAP effective tax rate with adjustments for the tax applicable to non-GAAP adjustments to Net income (loss), generally based upon the effective marginal tax rate of each adjustment.

Adjusted effective tax rate was approximately 24.3% for the three months ended September 30, 2024. The calculation is based on a ratio where the numerator is the adjusted income tax expense of $23,192 and the denominator is $95,253, which equals adjusted net income of $72,061 plus adjusted income tax expense. 2. Adjusted effective tax rate was approximately 22.9% for the three months ended September 30, 2023. The calculation is based on a ratio where the numerator is the adjusted income tax expense of $20,528 and the denominator is $89,601, which equals adjusted net income of $69,073 plus adjusted income tax expense.
