(“TransMedics”) (Nasdaq: TMDX), a medical technology company that is transforming organ transplant therapy for patients with end-stage lung, heart, and liver failure, today reported financial results for the quarter ended September 30, 2025.

Recent Highlights

“Overall, we are very pleased with our third quarter performance and the significant progress our team is making across multiple growth initiatives in the U.S. and globally.

Third Quarter 2025 Financial Results

Total revenue for the third quarter of 2025 was $143.8 million, a 32% increase compared to $108.8 million in the third quarter of 2024. The increase was due primarily to the increase in utilization of the Organ Care System ("OCS"), primarily in Liver and Heart through the National OCS Program ("NOP") and related NOP service revenue fueled by the continued expansion and utilization of our aviation fleet.

Gross margin for the third quarter of 2025 was 59%, compared to 56% in the third quarter of 2024.

Operating expenses for the third quarter of 2025 were $61.3 million, compared to $56.9 million in the third quarter of 2024. The increase in operating expenses was driven primarily by

increased research and development investment as well as investment throughout the organization to support the growth of the company. Third quarter operating expenses in 2025 included $8.7 million of stock compensation expense compared to $7.6 million of stock compensation expense in the third quarter of 2024.

Net income for the third quarter of 2025 was $24.3 million, or 17% of revenue, compared to $4.2 million in the third quarter of 2024.

Cash was $466.2 million as of September 30, 2025.

2025 Financial Outlook

TransMedics is raising the midpoint and narrowing the range of its full year 2025 revenue guidance to $595 million to $605 million, which represents 36% growth at the midpoint compared to the company's prior year revenue.
