TransMedics Reports Fourth Quarter and Full Year 2025 Financial Results

Operating expenses for the fourth quarter of 2025 were $72.1 million, compared to $63.4 million in the fourth 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. Fourth quarter operating expenses in 2025 included $9.1 million of stock compensation expense compared to $10.4 million of stock compensation expense in the fourth quarter of 2024.

Net income for the fourth quarter of 2025 was $105.4 million, or 66% of revenue, compared to $6.9 million in the fourth quarter of 2024. This includes a net income tax benefit of $83.8 million, primarily driven by a one-time benefit of $103.3 million from the release of the Company's valuation allowance related to deferred tax assets.

Full Year 2025 Financial Results
Total revenue for the full year of 2025 was $605.5 million, an 37% increase compared to $441.5 million for the full year of 2024. The increase was driven primarily by the increase in utilization of the OCS across all three organs through the NOP as well as additional revenue generated by TransMedics logistics services.

Gross margin for the full year of 2025 was 60%, compared to 59% in the full year of 2024. The change from prior year was a result of increased efficiencies in transplant logistics and benefits of scale.

Operating expenses for the full year of 2025 were $254.2 million, compared to $224.6 million in the full year of 2024. The increase in operating expense was driven primarily by increased research and development investment as well as investment throughout the organization to support the growth of the company. Full year operating expenses in 2025 included $35.5 million of stock compensation expense compared to $31.7 million of stock compensation expense in the full year of 2024.

Net income for the full year of 2025 was $190.3 million, or 31% of revenue, compared to $35.5 million in the full year of 2024. This includes a net income tax benefit of $82.8 million, primarily driven by a one-time benefit of $103.3 million from the release of the Company's valuation allowance related to deferred tax assets.

Cash was $488.4 million as of December 31, 2025 compared to $466.2 million as of September 30, 2025.

2026 Financial Outlook
TransMedics expects total revenue for the full year 2026 to be in the range of $727 million to $757 million, which represents 20% to 25% growth compared to the company's prior year revenue.
