Q4 and Full Year 2021 Financial Results March 4, 2022 Exhibit 99.2

Forward-Looking Statements Certain statements made in this presentation are “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Words such as “estimates,” “projects,” “expects,” “anticipates,” “forecasts,” “plans,” “intends,” “believes,” “seeks,” “may,” “will,” “would,” “should,” “future,” “propose,” “target,” “goal,” “objective,” “outlook” and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside the control of Fathom Digital Manufacturing Corporation (“Fathom”) that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Important factors, among others, that may affect actual results or outcomes include: the inability to recognize the anticipated benefits of our business combination with Altimar Acquisition Corp. II (“Altimar”); changes in general economic conditions, including as a result of the COVID-19 pandemic; the outcome of litigation related to or arising out of the business combination, or any adverse developments therein or delays or costs resulting therefrom; the ability to meet the New York Stock Exchange’s listing standards following the consummation of the business combination; costs related to the business combination and additional factors discussed in Altimar’s final prospectus/proxy statement filed with the Securities and Exchange Commission (the “SEC”) on December 3, 2021 (the “Proxy Statement/Prospectus”) and the documents of Altimar and Fathom filed, or to be filed, with the SEC. If any of the risks described above materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by our forward-looking statements. There may be additional risks that Fathom does not presently know or that Fathom currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Fathom’s expectations, plans or forecasts of future events and views as of the date of this presentation. Although Fathom may elect to update these forward-looking statements at some point in the future, Fathom specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Fathom’s assessments as of any date subsequent to the date of this press release. Accordingly, undue reliance should not be placed upon the forward-looking statements. Disclaimers

Non-GAAP Information This presentation includes Adjusted Net Income and Adjusted EBITDA, which are non-GAAP financial measures that we use to supplement our results presented in accordance with U.S. GAAP. We believe Adjusted Net Income and Adjusted EBITDA are useful in evaluating our operating performance, as they are similar to measures reported by our public competitors and regularly used by security analysts, institutional investors and other interested parties in analyzing operating performance and prospects. Adjusted Net Income and Adjusted EBITDA are not intended to be a substitute for any U.S. GAAP financial measure and, as calculated, may not be comparable to other similarly titled measures of performance of other companies in other industries or within the same industry. We define and calculate Adjusted Net Income as net loss before the impact of any increase or decrease in the estimated fair value of the Company’s warrants or earnout shares. We define and calculate Adjusted EBITDA as net losses before the impact of interest income or expense, income tax expense and depreciation and amortization, and further adjusted for the following items: stock-based compensation, transaction-related costs, and certain other non-cash and non-core items, as described in the reconciliation included in the appendix to this press release. Adjusted EBITDA margin represents Adjusted EBITDA divided by total revenue. We include these non-GAAP financial measures because they are used by management to evaluate Fathom’s core operating performance and trends and to make strategic decisions regarding the allocation of capital and new investments. Adjusted EBITDA excludes certain expenses that are required in accordance with U.S. GAAP because they are non-recurring (for example, in the case of transaction-related costs), non-cash (for example, in the case of depreciation and amortization, stock-based compensation) or are not related to our underlying business performance (for example, in the case of interest income and expense). Information reconciling forward-looking Adjusted EBITDA to GAAP financial measures is unavailable to Fathom without unreasonable effort. The company is not able to provide reconciliations of forward-looking Adjusted EBITDA to GAAP financial measures because certain items required for such reconciliations are outside of Fathom's control and/or cannot be reasonably predicted, such as the provision for income taxes. Preparation of such reconciliations would require a forward-looking balance sheet, statement of income and statement of cash flow, prepared in accordance with GAAP, and such forward-looking financial statements are unavailable to Fathom without unreasonable effort. Fathom provides a range for its Adjusted EBITDA forecast that it believes will be achieved, however it cannot accurately predict all the components of the Adjusted EBITDA calculation. Fathom provides an Adjusted EBITDA forecast because it believes that Adjusted EBITDA, when viewed with the company's results under GAAP, provides useful information for the reasons noted above. However, Adjusted EBITDA is not a measure of financial performance or liquidity under GAAP and, accordingly, should not be considered as an alternative to net income or cash flow from operating activities as an indicator of operating performance or liquidity. As described in the Proxy Statement/Prospectus, during 2020 Fathom completed the acquisitions of Incodema Holdings, Inc., Newchem, Inc., GPI Prototype and Manufacturing Services, LLC, Dahlquist Machine, Inc., Majestic Metals, LLC, and Mark Two Engineering, Inc. (the “2020 Acquisitions”). During 2021 we completed the acquisitions of Summit Tooling, Inc., Summit Plastics, LLC, Centex Machine and Welding, Inc., Laser Manufacturing, Inc. and Screenshot Precisions, LLC d/b/a Micropulse West and Precisions Process Corp. (the “2021 Acquisitions”). Pro forma revenue gives pro forma effect to the 2020 Acquisitions and 2021 Acquisitions, as though such transactions occurred on January 1, 2020. Financial Disclosure Disclaimer Fathom has not yet completed its reporting process for the three and twelve months ended December 31, 2021. Full financial statements for these periods will be filed on or before March 31, 2022. The preliminary unaudited results presented herein are based on Fathom’s reasonable estimates and the information available at this time. The amounts reported herein are subject to various adjustments that are still under review, including potential adjustments relating to changes in the estimated fair value of warrants and earnout shares, purchase accounting and provision for income taxes. Such adjustments may be material and could impact the results reported herein. Disclaimers, continued

Specifically, cost of revenue included a reclassification of certain expenses equal to 6.2% and 0.5% of revenue for the twelve months ended December 31, 2021, and December 31, 2020, respectively, as well as 4.4% and 0.5% of revenue for the three months ended December 31, 2021, and December 31, 2020, respectively. Additionally, SG&A included a reclassification of certain expenses equal to 3.4% net of revenue for both the twelve months ended December 31, 2021, and December 31, 2020, as well as 1.8% and 3.4% of revenue for the three months ended December 31, 2021, and December 31, 2020, respectively. Prior to the Company’s ownership of applicable acquired entities, these expenses were recorded inconsistently. The accounting reclassification had no impact on net income (loss). 2 Adjusted net income (loss) excludes acquisition expenses, transaction costs, and income statement impacts from the change in fair value related to both the earnout liability and the warrant liability. See reconciliation of adjusted net income in the Appendix.
