•Worldwide revenue of $116.3 million - an increase of 15.2% year over year

•Positive cash flow generation of $8.1 million in second quarter 2024

MASON, Ohio, July 30, 2024 - 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 second quarter 2024 financial results.

"Our second quarter results reflect strong growth worldwide, underscored by our pain management and open AtriClip® franchises, as we continued to deliver exceptional patient outcomes across all therapies, while driving positive cash flow," said Michael Carrel, President and Chief Executive Officer at AtriCure. "Entering the second half of 2024, we are advancing several clinical initiatives including our LeAAPS™ stroke reduction trial and introducing new products across our markets, with two cryoSPHERE® probes to reduce freeze times and the most advanced, smallest profile AtriClip® device. We also remain focused on improving the efficiency of our business."

Second Quarter 2024 Financial Results

Revenue for the second quarter 2024 was $116.3 million, an increase of 15.2% over second quarter 2023 revenue (15.4% on a constant currency basis), reflecting continued adoption of our products by physicians globally and an acceleration in U.S. pain management and international franchises, as well as U.S. open appendage management which outpaced overall growth. On a sequential basis, worldwide revenue for the second quarter 2024 increased approximately 7% from the first quarter.

U.S. revenue was $95.5 million, an increase of $10.6 million or 12.5%, compared to the second quarter 2023. U.S. revenue growth was driven by sales across key product lines, highlighted by cryoSPHERE® probes for post-operative pain management, the AtriClip® Flex·V® device in appendage management, and the ENCOMPASS® clamp in open ablation. International revenue increased $4.7 million or 29.4% (30.4% on a constant currency basis) to $20.7 million, realizing significant growth across all franchises and most major geographic regions.

Gross profit for the second quarter 2024 was $86.8 million compared to $77.1 million for the second quarter 2023. Gross margin was 74.7% for the second quarter 2024, a decrease of 168basis points from the second quarter 2023, reflecting less favorable geographic and product mix, as well as increased product costs compared to the prior year. Loss from operations for the second quarter 2024 was $7.2 million, compared to $4.1 million for the second quarter 2023. Basic and diluted net loss per share was $0.17 for the second quarter 2024, compared to $0.11 for the second quarter 2023.

Adjusted EBITDA for the second quarter 2024 is $7.8 million, a decrease of $0.2 millionfromsecond quarter of 2023. Adjusted loss per share for the second quarter 2024 was $0.17, compared to $0.12 for the second quarter 2023.

Constant currency revenue, adjusted EBITDA and adjusted 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.

2024 Financial Guidance

AtriCure now expects full year 2024 revenue of approximately $456 million to $461 million, reflecting growth of approximately 15% at the midpoint of the range. Management continues to expect full year 2024 Adjusted EBITDA of approximately $26 million to $29 million, with improvements annually thereafter. Projected full year 2024 adjusted EBITDA represents a 34% to 49% increase over full year 2023. Full year 2024 adjusted loss per share is expected to be in the range of $0.74 to $0.82.

This press release also includes forward-looking projected financial information that is based on current estimates and forecasts. Actual results could differ materially. For details on the uncertainties that may cause our actual results to be materially different than those expressed in our forward-looking statements, visit http://www.atricure.com/forward-looking-statements as well as our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q which contain risk factors.

We assume no obligation to update any forward-looking statements contained in this release as a result of new information or future events or developments, except as may be required by law.

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, acquisition costs, 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 loss per share is a non-GAAP measure which calculates the net loss per share before non-cash adjustments in fair value of contingent consideration liabilities, impairment of intangible assets, debt extinguishment and legal settlements. A reconciliation of adjusted 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 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.
