A copy of the press release is attached hereto as Exhibit 99.1.

Important Additional Information about the Business Combination and Where to Find It:

In connection with the Business Combination, a registration statement on Form S-4 (as amended, the “Registration Statement”) has been declared effective by the Securities and Exchange Commission (the “SEC”), which includes a proxy statement of Altimar with respect to the Special Meeting. Altimar’s shareholders and other interested persons are advised to read the Registration Statement and combined proxy statement/prospectus contained therein and the documents filed in connection therewith, as these materials will contain important information about Altimar, Fathom OpCo and the Business Combination. The Proxy Statement will be mailed to Altimar’s shareholders who were holders of record as of November 29, 2021. The documents filed by Altimar with the SEC may be obtained free of charge at the SEC’s website at www.sec.gov. In addition, the documents filed by Altimar may be obtained free of charge from Altimar at www.atmr.altimaracquisition.com.

Altimar and certain of its respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the shareholders of Altimar, in favor of the approval of the Business Combination. For information regarding Altimar’s directors and executive officers, please see Altimar’s initial public offering prospectus filed with the SEC on February 4, 2021. Additional information regarding the interests of those participants and other persons who may be deemed participants in the transaction may be obtained by reading the Proxy Statement. Free copies of these documents may be obtained as described above.

Non-Solicitation

The disclosure herein is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed Business Combination and shall not constitute an offer to sell or a solicitation of an offer to buy the securities of Altimar, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction. No offer of securities shall be made except by means of a definitive document.

Forward-Looking Statements

Certain statements made in this Current Report on Form 8-K, and oral statements made from time to time by representatives of Altimar are “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995.

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 Altimar’s control, 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 of Altimar to complete the proposed Business Combination with Fathom OpCo; the risk of delays in the expected timing of the closing of the proposed Business Combination with Fathom OpCo; the risk that Altimar shareholder approval of the proposed Business Combination is not obtained; the inability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, the amount of funds available in Altimar’s trust account following any redemptions by Altimar’s shareholders; 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 proposed 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 proposed Business Combination; costs related to the proposed Business Combination; those factors discussed in Altimar’s initial public offering prospectus under the heading “Risk Factors”; those factors discussed in the Proxy Statement under the heading “Risk Factors”; those factors disclosed in Altimar’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2021; those factors disclosed in Altimar’s Quarterly Report on Form 10-Q/A for the quarter ended September 30, 2021 and other documents of Altimar filed, or to be filed, with the SEC.
