Houston, Texas and Tuebingen, Germany, March 17, 2020 – Immatics Biotechnologies GmbH (“Immatics” or the “Company”), a clinical-stage biopharmaceutical company active in the discovery and development of T cell redirecting cancer immunotherapies, today announced it has entered into a definitive business combination agreement with Arya Sciences Acquisition Corp. (NASDAQ: ARYA) (“Arya”), a special purpose acquisition company, sponsored by Perceptive Advisors.

In addition to the funds held in Arya’s trust account, a group of leading US healthcare investors has committed to participate in the transaction through a ~$104 million common stock PIPE. Investors in the PIPE include Perceptive Advisors, Redmile Group, Federated Hermes Kaufmann Funds, RTW Investments, Sphera Funds, and an additional healthcare focused investor, as well as current existing Company shareholders including dievini Hopp BioTech, AT Impf and Wellington Partners.

Immatics will receive gross proceeds of up to $252 million at the closing of the transaction and will continue to operate under the Immatics management team headed by Chief Executive Officer Harpreet Singh, Ph.D. The respective boards of directors of both Arya and Immatics have approved the proposed transaction. Completion of the transaction, which is expected in the second quarter of 2020, is subject to approval of Arya’s and Immatics’ shareholders and the satisfaction of certain other customary closing conditions.

Adam Stone, Chief Investment Officer of Perceptive Advisors and CEO of Arya, stated: “Immatics has established a leadership position in the rapidly evolving area of T cell receptor (TCR) based cell therapies. Immatics’ TCR-based drug candidates are designed to disrupt the current solid tumor treatment paradigm and open new avenues for cancer patients.” Adam Stone further commented: “Our goal when we formed Arya was to identify a unique company with disruptive potential. Immatics’ expertise in identifying cancer targets and developing the right TCRs for immunotherapies, provided exactly that opportunity for this investment vehicle. We look forward to working closely with the Immatics’ team and are excited about the potential their technologies represent – to both patients and investors.”

Harpreet Singh, Ph.D., Co-Founder and CEO of Immatics commented: “We greatly value the commitment from Perceptive Advisors and other top-tier investors who are participating in this transaction, as well as our existing investors who have supported the development of Immatics to date. We believe this business combination with Arya represents a unique opportunity to transition our company onto a global stage. Access to the US capital markets will be critical to our ability to fuel our development plans and to advance Immatics’ innovative immunotherapies through the clinic as part of our mission to improve treatment options for cancer patients.”

Immatics leverages advanced technologies and biologic insight to identify otherwise inaccessible and intracellular drug targets as a basis for a broad range of cancer immunotherapies designed to overcome the current limitations in immuno-oncology. The company is actively using these targets to develop novel T cell receptors to enable a robust and specific T-cell response against cancer cells. The Company has two distinct product classes, Adoptive Cell Therapies (ACT) and TCR Bispecifics, and is advancing product candidates in both classes in the Company’s proprietary pipeline with several clinical-stage ACT lead products. Additionally, the Company has several large-scale collaborations with global leaders in the pharmaceutical industry.
