Fourth Quarter 2025 Financial Results

Revenue for the fourth quarter 2025 was $140.5 million, an increase of 13.1% over fourth quarter 2024 revenue (12.1% on a constant currency basis), reflecting growth across the business globally, partially offset by declines in our minimally invasive devices. U.S. revenue was $114.3 million, an increase of $12.8 million or 12.6%, compared to fourth quarter 2024. U.S. revenue growth was driven by sales of our cryoSPHERE MAX^® probe for post-operative pain management, AtriClip^® FLEX-Mini^® device for appendage management and the EnCompass^® clamp in open ablation. International revenue increased $3.5 million or 15.3% (9.9% on a constant currency basis) to $26.2 million, with growth in most of our key international markets.

Gross profit for the fourth quarter 2025 was $105.3 million compared to $92.6 million for the fourth quarter 2024. Gross margin was 75.0%, an increase of 45 basis points from the fourth quarter 2024, driven by more favorable product mix. Income from operations for the fourth quarter 2025 was $2.5 million, compared to a loss from operations of $14.5 million for the fourth quarter 2024. Basic and diluted net income per share was $0.04 for the fourth quarter 2025, compared to net loss per share of $0.33 for the fourth quarter 2024.

Adjusted EBITDA for the fourth quarter 2025 was $19.9 million, compared to $12.7 million for fourth quarter of 2024. Adjusted income per share for the fourth quarter 2025 was $0.06 compared to adjusted loss per share of $0.08 for the fourth quarter 2024.

Forward-Looking Statements

Except for historical information, certain statements in this press release, including financial guidance and outlook, are forward-looking in nature and are subject to risks, uncertainties and assumptions about us.

Use of Non-GAAP Financial Measures

To supplement AtriCure's condensed consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, AtriCure provides certain non-GAAP financial measures in this release as supplemental financial metrics.

Revenue reported on a constant currency basis is a non-GAAP measure, calculated by applying previous period foreign currency exchange rates to each of the comparable periods. Management analyzes revenue on a constant currency basis to better measure the comparability of results between periods. Because changes in foreign currency exchange rates have a non-operating impact on revenue, the Company believes that evaluating growth in revenue on a constant currency basis provides an additional and meaningful assessment of revenue to both management and investors.

Adjusted EBITDA is calculated as net income (loss) before other income/expense (including interest), income tax expense, depreciation and amortization expense, share-based compensation expense, and non-recurring charges that are not reflective of the operational results of the Company's core business and may affect comparability of results period-over-period. Non-recurring charges include acquisition costs, acquired-in-process research and development (IPR&D) and related milestone payments arising from asset acquisitions, legal settlement costs, impairment of intangible assets and change in fair value of contingent consideration liabilities.

Management believes in order to properly understand short-term and long-term financial trends, investors may wish to consider the impact of these excluded items in addition to GAAP measures. The excluded items vary in frequency and/or impact on our continuing results of operations and management believes that the excluded items are typically not reflective of our ongoing core business operations and financial condition. Further, management uses adjusted EBITDA for both strategic and annual operating planning. A reconciliation of adjusted EBITDA reported in this release to the most comparable GAAP measure for the respective periods appears in the table captioned "Reconciliation of Non-GAAP Adjusted Income (Adjusted EBITDA)" later in this release.

Adjusted income (loss) per share is a non-GAAP measure which calculates the net income (loss) per share before non-cash adjustments in fair value of contingent consideration liabilities, acquired IPR&D and related milestone payments arising from asset acquisitions, legal settlement costs, impairment of intangible assets and debt extinguishment. A reconciliation of adjusted income (loss) per share reported in this release to the most comparable GAAP measure for the respective periods appears in the table captioned "Reconciliation of Non-GAAP Adjusted Income (Loss) Per Share" later in this release.

The non-GAAP financial measures used by AtriCure may not be the same or calculated in the same manner as those used and calculated by other companies. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for AtriCure's financial results prepared and reported in accordance with GAAP. We urge investors to review the reconciliation of these non-GAAP financial measures to the comparable GAAP financials measures included in this press release, and not to rely on any single financial measure to evaluate our business.
