Additional Information and Where to Find It

Altimar intends to file a registration statement on Form S-4 with the Securities and Exchange Commission (the “SEC”), which will include a proxy statement and a prospectus of Altimar, and each party will file other documents with the SEC regarding the proposed transaction. A definitive proxy statement/prospectus will also be sent to the stockholders of Altimar, seeking any required stockholder approval. Before making any voting or investment decision, investors and security holders of Altimar are urged to carefully read the entire registration statement and proxy statement/prospectus, when they become available, and any other relevant documents filed with the SEC, as well as any amendments or supplements to these documents, because they will contain important information about the proposed transaction. 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.altimarspac.com.

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 the Company are “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Statements regarding the proposed business combination and expectations regarding the combined business are “forward looking statements.” In addition, 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 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 contemplated transactions with Owl Rock and Dyal; the risk that the approval of the stockholders of Altimar for 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 stockholders; the ability to meet the NYSE’s listing standards following the consummation of the transactions contemplated by the proposed business combination; costs related to the proposed business combination; and those factors discussed in Altimar’s prospectus, dated October 22, 2020 under the heading “Risk Factors,” and other documents of Altimar filed, or to be filed, with the SEC. Altimar does not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Participants in the Solicitation

Altimar and certain of its respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the stockholders of Altimar, in favor of the approval of the business combination. 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 registration statement and the proxy statement/prospectus and other relevant documents filed with the SEC when they become available. Free copies of these documents may be obtained as described in the preceding paragraph.

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 potential transaction 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.
