AtriCure Reports First Quarter 2024 Financial Results

• Worldwide revenue of $108.9 million – an increase of 16.4% year over year

AtriCure, Inc. ((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 2024 financial results.

"We are proud to announce a strong start to 2024, marked by growth across each of our franchises worldwide," said Michael Carrel, President and Chief Executive Officer at AtriCure. "We remain diligently focused on expanding the reach of our solutions for patients with advanced forms of Afib, managing the LAA in patients undergoing cardiac surgery and reducing post-operative pain. To that end, we look forward to advancing our clinical research initiatives and launching several new products this year."

First Quarter 2024 Financial Results

Revenue for the first quarter 2024 was $108.9 million, an increase of 16.4% over first quarter 2023 revenue (16.3% on a constant currency basis), reflecting continuing adoption of our products by physicians globally. On a sequential basis, worldwide revenue for the first quarter 2024 increased approximately 2.2% from the fourth quarter 2023.

U.S. revenue was $90.2 million, an increase of $12.1 million or 15.4%, compared to the first quarter 2023. U.S. revenue growth was driven by sales across key product lines, highlighted by Hybrid AF™ Therapy procedures using the EPi-Sense System in minimally invasive ablation, the ENCOMPASS^® clamp in open ablation, the AtriClip^® Flex·V^® device in appendage management, and the cryoSPHERE^® probe for post-operative pain management. U.S. revenue growth was partially offset by pressure in minimally invasive appendage management products, primarily from a decline in the LARIAT^® system sales. International revenue increased $3.3 million or 21.5% (21.1% on a constant currency basis) to $18.6 million, with robust activity across all franchises and geographic regions.

Gross profit for the first quarter 2024 was $81.3 million compared to $69.6 million for the first quarter 2023. Gross margin was 74.7% for the first quarter 2024, showing improvement of 21 basis points from the first quarter 2023 and reflecting more favorable product and geographic mix. Loss from operations for the first quarter 2024 was $10.9 million, compared to $5.8 million for the first quarter 2023, driven by the $4.0 million gain from legal settlement in 2023. Basic and diluted net loss per share was $0.28 for the first quarter 2024, compared to $0.14 for the first quarter 2023.

Adjusted EBITDA for the first quarter 2024 is $2.8 million, an increase of $0.9 million over first quarter of 2023. Adjusted loss per share for the first quarter 2024 was $0.25, compared to $0.23 for the first 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

Full year 2024 revenue is projected to be approximately $459 million to $466 million, reflecting growth of approximately 15% to 17% over full year 2023. Management continues to expect full year 2024 Adjusted EBITDA of approximately $26 million to $29 million, with improvements annually thereafter. Full year 2024 adjusted EBITDA represents an approximately 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.

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.
