Exhibit 99.1
TransMedics Provides Additional Information on the Impact of the Release of the Valuation Allowance on Deferred Tax
Assets on Previously Reported Fourth Quarter Financial Results
Andover, Mass. – February 27, 2026 – TransMedics Group, Inc.
(“TransMedics”) (Nasdaq: TMDX), a medical technology company that is transforming organ transplant therapy for patients with end-stage lung, heart, and liver failure, today issued additional
information on the impact of the valuation allowance on deferred tax assets reported in the Company’s fourth quarter financial results for the year ended December 31, 2025.
As previously disclosed, in the fourth quarter of 2025, TransMedics released a $103.3 million U.S. tax valuation allowance, which drove recognition of a
net income tax benefit of $83.8 million in the fourth quarter. The Company released the U.S. tax valuation allowance because it determined that it had become more likely than not that future income would result in use of deferred tax assets.
TransMedics’ annual effective tax rate in 2025 was (77.0)%. TransMedics’ annual effective tax rate in 2025, without the impact of the tax
valuation allowance release, was 19.1%, a difference of 96.1 percentage points.
An annual effective tax rate of 19.1% applied to fourth quarter income
before income taxes of $21.6 million results in adjusted quarterly tax expense of $4.1 million. Fourth quarter net income was $105.4 million and net income per diluted share was $2.62. If the company applies an annual effective tax
rate of 19.1%, fourth quarter adjusted net income is $17.5 million and net income per diluted share is $0.47.
In future periods, TransMedics expects
to recognize a quarterly income tax provision more in line with U.S. statutory corporate income tax rates.
