Business Context and Reporting Period

This Form 10-K covers the fiscal year ended December 31, 2024. AtriCure, Inc. is a leading innovator in surgical treatments for atrial fibrillation (Afib), left atrial appendage (LAA) management, and post-operative pain management.

Key product lines include the Isolator Synergy (open ablation), EPi-Sense (minimally invasive ablation), cryoSPHERE (pain management), and AtriClip (LAA exclusion) systems.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Worldwide revenue increased 16.5% to $465.3 million, driven by adoption across all product lines and new launches. International revenue grew 25.6%.
• Product Launches: Significant 2024 launches included the EnCompass clamp (EU), EPi-Ease (FDA cleared), EnCapture clamp (FDA cleared), cryoSPHERE+ and cryoSPHERE MAX probes (pain management), and the AtriClip FLEX-Mini device.
• Expense Increases:
  • R&D Expenses: Increased 30.1% to $96.2 million, primarily due to a $12.0 million upfront payment for an exclusive licensing agreement for pulsed field ablation (PFA) technology and increased clinical trial activity (LeAAPS).
  • SG&A Expenses: Increased 15.1% to $291.4 million due to headcount growth and variable compensation, partially offset by a $7.5 million legal settlement gain recorded in 2023.
• Debt Restructuring: In January 2024, the company entered a new $125 million asset-based credit facility, resulting in a $1.4 million loss on debt extinguishment.

Guidance, Outlook, and Risks

Outlook and Strategy: Management expects to continue investing in product innovation, clinical science, and physician education. The company is focused on expanding the market for surgical ablation and LAA management, supported by updated societal guidelines (ESC, ACC/AHA) that upgraded LAA management to a Class 1 recommendation. The company believes its current cash and credit facility are sufficient for operations for at least the next 12 months.

Key Risks and Contingencies:

• Profitability: The company has a history of net losses and an accumulated deficit of $401.8 million. There is no assurance it will achieve or sustain profitability.
• Regulatory: Risks include failure to obtain FDA approvals for new indications, potential enforcement actions for off-label promotion, and reliance on third-party suppliers for sterilization (ethylene oxide concerns).
• Legal: A complaint was filed in February 2025 by former SentreHEART securityholders alleging breach of contract regarding PMA milestones, seeking up to $260 million. The company intends to vigorously defend this claim. Additionally, a False Claims Act investigation was dismissed in September 2024.
• Market: Competition from Medtronic and other entrants, as well as reimbursement pressures from third-party payors.

Investor Verification Checklist

• Cash Burn vs. Revenue Growth: Verify if the 16.5% revenue growth is sufficient to offset the widening net loss (increased from $30.4M to $44.7M) driven by R&D investments.
• Debt Covenants: Review the specific financial covenants (fixed charge coverage, minimum liquidity) in the new JPMorgan credit facility to ensure compliance.
• Legal Exposure: Monitor the status of the SentreHEART litigation filed in February 2025 and the potential impact of the $260 million claim.
• Clinical Trial Milestones: Track enrollment progress for the LeAAPS trial (over 4,200 enrolled as of year-end) and the BoxX-NoAF trial (protocol approved Q4 2024) as these drive future labeling and revenue.
• Supply Chain Resilience: Assess the impact of third-party sterilization constraints (ethylene oxide regulations) on product availability.
