(“ARYA”), at which ARYA’s proposed business combination (the “Business Combination”) with Immatics Biotechnologies GmbH (“Immatics”) will be considered and voted upon. While the registration statement has not yet become effective and the information contained therein is subject to change, it provides important information about ARYA, Immatics, TopCo and the Business Combination.

The registration statement containing the preliminary proxy statement/prospectus is available through the SEC’s website at www.sec.gov under TopCo’s filings.

Additional Information

In connection with the Business Combination, TopCo has filed a Registration Statement on Form F-4, which includes a preliminary prospectus of TopCo and preliminary proxy statement of ARYA. ARYA will mail a definitive proxy statement/prospectus and other relevant documents to its shareholders.

Shareholders will also be able to obtain copies of the definitive proxy statement/prospectus, without charge, once available, on the SEC website at www.sec.gov or by directing a request to: ARYA Sciences Acquisition Corp., 51 Astor Place, 10th Floor, New York, NY 10003.

ARYA, Immatics, TopCo and their respective directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of ARYA’s shareholders in connection with the Business Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of ARYA’s and Immatics’ directors and officers in the preliminary proxy statement/prospectus described above.
