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 third quarter 2023 financial results.

"We are excited to report another strong quarter at AtriCure, driven by the performance across our business globally. We also made progress against many strategic initiatives in our pillars of innovation, education and clinical science," said Michael Carrel, President and Chief Executive Officer at AtriCure. "To that end, we continue to prioritize thoughtful investments while demonstrating meaningful operating leverage in our business.

Third Quarter 2023 Financial Results

Revenue for the third quarter 2023 was $98.3 million, an increase of 18.1% over third quarter 2022 revenue (17.3% on a constant currency basis). Our worldwide revenue growth reflects continuing adoption of our products by physicians for the treatment of patients with Afib, LAA management and post-operative pain management.

U.S. revenue was $81.7 million, an increase of $11.9 million or 17.1%, compared to the third quarter 2022. U.S. revenue growth was driven by sales across product lines, highlighted by sales of the EnCompass^® clamp in open ablation, cryoSPHERE^® probe for post-operative pain management and the AtriClip^® Flex·V^® device in appendage management. International revenue increased $3.1 million or 23.2% (18.7% on a constant currency basis) to $16.6 million, across all franchises and geographic regions. On a sequential basis, worldwide revenue for the third quarter 2023 decreased approximately 2.6% from the second quarter 2023 due to normal seasonality of procedures in summer months.

Gross profit for the third quarter 2023 was $73.9 million compared to $61.7 million for the third quarter 2022. Gross margin was 75.2% for the third quarter 2023, showing improvement of 110 basis points from the third quarter 2022. The current quarter reflects leverage of our operations and production efficiencies, partially offset by pressure from geographic and product mix. Loss from operations for the third quarter 2023 was $8.1 million, compared to $10.7 million for the third quarter 2022, reflecting strong revenue growth, cost efficiencies, and improving operating leverage. Basic and diluted net loss per share was $0.20 for the third quarter 2023, compared to $0.27 for the third quarter 2022.

Adjusted EBITDA was positive for the third quarter 2023 at $4.7 million, compared to negative $0.7 million for third quarter of 2022. Adjusted loss per share for the third quarter 2023 was $0.20, compared to $0.27 for the third quarter 2022.

Constant currency revenue, adjusted EBITDA and adjusted loss per share are non-GAAP measures. We discuss these non-GAAP measures and provide reconciliations to GAAP measures later in this release.

2023 Financial Guidance

Full year 2023 revenue is projected to be $394 million to $396 million, reflecting growth of approximately 19% to 20% over full year 2022. Management now expects full year 2023 positive adjusted EBITDA of approximately $18 million to $20 million, and full year 2023 adjusted loss per share of approximately $0.74 to $0.76.

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 loss before other income/expense (including interest), income tax expense, depreciation and amortization expense, share-based compensation expense, acquisition costs, legal settlements, 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 (Loss) (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 and legal settlements. A reconciliation of adjusted loss income 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.
