Adjusted EBITDA financial
"Adjusted EBITDA for the first quarter 2026 was $17.1 million, an increase of $8.3 million or 95% from the first quarter 2025."
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
constant currency basis financial
"Worldwide revenue for the first quarter 2026 was $141.2 million, an increase of 14.3% ... (12.8% on a constant currency basis)."
A "constant currency basis" is a way companies compare financial results by removing the effects of changing exchange rates between different currencies. It helps show how the business is really performing, without the confusion caused by currency value swings, much like adjusting for inflation to see true growth.
non-GAAP financial measures financial
"Constant currency revenue, adjusted EBITDA and adjusted income (loss) per share are non-GAAP financial measures."
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
share-based compensation expense financial
"Share-based compensation expense | 11,273 | | | 9,630 |"
Share-based compensation expense is the accounting cost a company records when it pays employees or executives with stock, stock options, or other equity instead of cash. It matters to investors because it reduces reported profits and can dilute existing owners’ stake over time — like a bakery paying workers with slices of cake instead of money, leaving fewer slices for original owners and changing each slice’s value.
forward-looking statements regulatory
"Except for historical information, certain statements in this press release, including financial guidance and outlook, are forward-looking in nature..."
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Adjusted income (loss) per share financial
"Adjusted income (loss) per share is a non-GAAP measure which calculates the net income (loss) per share before non-cash adjustments..."
Revenue $141.2M +14.3% YoY
Net income $0.1M vs. $6.7M loss prior year
Adjusted EBITDA $17.1M +95% YoY
Gross margin 77.4% +246 bps YoY
Guidance

For 2026, AtriCure projects revenue of $600M–$610M, adjusted EBITDA of $80M–$82M, adjusted EPS of $0.09–$0.15 and net EPS of $0.00–$0.04, with continued positive cash flow.

AtriCure Reports First Quarter 2026 Financial Results
First Quarter 2026 worldwide revenue of $141.2 million, an increase of 14.3% year over year
First Quarter 2026 profitability improved, with net income of $0.1 million and adjusted EBITDA of $17.1 million
U.S. revenue growth accelerated to 14.9%, driven by AtriClip FLEX-Mini®, cryoSPHERE® MAX, EnCompass® clamp, and AtriClip PRO-Mini®
MASON, Ohio, May 6, 2026 – AtriCure, Inc. (Nasdaq: ATRC), a leading innovator in surgical treatments and therapies for atrial fibrillation (Afib), left atrial appendage (LAA) management and post-operative pain management, today announced first quarter 2026 financial results.

“Our first quarter results reflect the durability of AtriCure’s growth model, fueled by disciplined execution and increased adoption of our innovative products,” said Michael Carrel, President and Chief Executive Officer at AtriCure. “Strong revenue growth, combined with improving profitability and meaningful advancement across our clinical initiatives, gives us confidence that we are building a foundation to drive the next era of growth and value creation for AtriCure and our shareholders.”
First Quarter 2026 Financial Results
Worldwide revenue for the first quarter 2026 was $141.2 million, an increase of 14.3% over first quarter 2025 revenue (12.8% on a constant currency basis). U.S. revenue was $116.2 million, an increase of $15.1 million or 14.9%, compared to the first quarter 2025. U.S. revenue growth was driven by sales of our cryoSPHERE® MAX probe for post-operative pain management, AtriClip FLEX-Mini® and AtriClip PRO-Mini® devices for appendage management, and the EnCompass® clamp in open ablation. International revenue increased $2.6 million or 11.5% (3.3% on a constant currency basis) to $25.0 million, with growth across most of our direct markets in appendage management, open ablation, and pain management.
Gross profit for the first quarter 2026 was $109.3 million compared to $92.6 million for the first quarter 2025. Gross margin was 77.4% for the first quarter 2026, an increase of 246 basis points from the first quarter 2025, driven primarily by favorable product and geographic mix. Income from operations for the first quarter 2026 was $0.5 million, compared to a loss from operations of $6.0 million for the first quarter 2025. Basic and diluted net income per share was breakeven at $0.00 for the first quarter 2026, compared to net loss per share of $0.14 for the first quarter 2025.
Adjusted EBITDA for the first quarter 2026 was $17.1 million, an increase of $8.3 million or 95% from the first quarter 2025. For the first quarter 2026, net income per share and adjusted income per share were breakeven at $0.00, compared to $0.14 net loss per share and adjusted loss per share for the first quarter 2025. For both 2026 and 2025, the per share amounts are equivalent because there were no reconciling items between the GAAP and non-GAAP results for the periods.
Constant currency revenue, adjusted EBITDA and adjusted income (loss) per share are non-GAAP financial measures. We discuss these non-GAAP financial measures and provide reconciliations to GAAP measures later in this release.
2026 Financial Guidance
Full year 2026 revenue is projected to be approximately $600 million to $610 million, and management also projects full year 2026 Adjusted EBITDA of approximately $80 million to $82 million. Full year 2026 adjusted earnings per share is expected to be in the range of $0.09 to $0.15, and net earnings per share is expected to be in the range of $0.00 to $0.04. Additionally, management expects continued positive cash flow generation for 2026.

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. Our business and operations are subject to a variety of risks and uncertainties and, consequently, actual results may differ materially from those projected by any forward-looking statements. These risks and uncertainties include, but are not limited to, the following: our estimate of the market for our products; the rate and degree of market acceptance of our products; negative clinical data; competition from existing and new products and procedures, including the development of drugs or catheter-based technologies; our reliance on independent distributors to sell our products; inventory-related charges; the timing of and ability to obtain and maintain regulatory clearances and approvals for our products; impacts of rising healthcare costs; our ability to comply with extensive FDA regulations; the timing of and ability to obtain third party payor reimbursement of procedures utilizing our products; unfavorable publicity; the potential impact of any acquisitions, mergers, dispositions, joint ventures or investments we may make; disruptions to our manufacturing operations; the impact of tariffs or other restrictive trade measures; our failure to properly manage growth; disruptions of critical information systems or material breaches in the security of our systems; our ability to manage our intellectual property rights to provide meaningful protection; fluctuation of quarterly financial results; fluctuations in foreign currency exchange rates; reliance on third party manufacturers and suppliers; and litigation, administrative or other proceedings. These risks and uncertainties, as well as others, are discussed in greater detail in our filings with the Securities and Exchange Commission ("SEC"), including our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 19, 2026. There may be additional risks of which we are not presently aware or that we currently believe are immaterial which could have an adverse impact on our business. Any forward-looking statements are based on our current expectations, estimates and assumptions regarding future events and are applicable only as of the dates of such statements. We make no commitment to revise or update any forward-looking statements in order to reflect events or circumstances that may change.
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 for 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 changes 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. No reconciliation is reported in this release to the most comparable GAAP measure for the respective periods as the amounts are equivalent because there were no reconciling items between the GAAP and non-GAAP results for the periods.
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.
