TransMedics Group, Inc.

Item 1. Legal Proceedings.

On February 14, 2025, a class action captioned Jewik v. TransMedics Group, Inc., et al., Case No. 1:25-cv-10385, was filed against the Company and certain of its current and former officers in the United States District Court for the District of Massachusetts. The complaint purports to assert claims pursuant to Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and SEC Rule 10b-5 promulgated thereunder, on behalf of a putative class of investors who purchased or otherwise acquired the Company’s shares between the Class Period, February 28, 2023 and January 10, 2025. Plaintiff seeks to recover unspecified damages allegedly caused by purported misstatements and omissions contained in certain risk disclosures set forth in our 2022 and 2023 Annual Reports. The complaint alleges the disclosures at issue were false or misleading, because they failed to describe what plaintiff alleges were coercive business and marketing tactics, anticompetitive conduct and fraudulent billing activities on the part of the Company. The complaint claims these alleged statements and omissions operated to artificially inflate the price paid for our common stock during the Class Period.

On April 2, 2025, another purported stockholder filed a putative class action lawsuit against the Company and certain of its current and former officers, also in the United States District Court for the District of Massachusetts (Collins v. TransMedics Group, Inc., et al., Case No. 1:25-cv-10778). The Collins complaint alleged claims substantially similar to those alleged in the Jewik action and also sought unspecified damages. On May 22, 2025, the court consolidated the Jewik and Collins actions and appointed the Peace Officers’ Annuity and Benefit Fund of Georgia and Oguzhan Altun as lead plaintiffs (the “Lead Plaintiff”). Lead Plaintiff’s consolidated amended complaint is due August 8, 2025.

From time to time, we may be involved in other legal proceedings or investigations, which could have an adverse impact on our reputation, business and financial condition and divert the attention of our management from the operation of our business.
