• Strong 2025 Financial Performance

  The company reported a significant reduction in net loss to $44.6 million in 2025 from $113.3 million in 2024, and achieved positive Adjusted EBITDA of $68.9 million, a substantial improvement from negative figures in prior years. Revenue increased by 26% to $747.1 million in 2025.

• Multiple Ongoing DOJ Investigations

  The company is subject to several ongoing Department of Justice inquiries, including grand jury subpoenas from 2021, a Subpoena Duces Tecum from April 2023, and a new civil investigative demand received on December 12, 2025, seeking information related to Zio AT and reimbursement claims. An appeal is pending regarding a May 2025 District Court order to disclose certain documents.

• Persistent FDA Compliance Challenges

  Remediation efforts are ongoing in response to a May 2023 FDA warning letter and 483 observations from August 2022 and July 2024, related to medical device reporting and quality system requirements. The company received 510(k) clearances in October 2024 for Zio AT design updates.

• Active Patent Litigation

  iRhythm is defending against patent infringement lawsuits filed by Welch Allyn (February 2024, with USPTO instituting re-examination of four patents on January 20, 2026) and Bardy Diagnostics (December 2024, with ongoing motions to amend pleadings and counterclaims).

This annual 10-K filing provides comprehensive audited financial results for 2025, detailing a significant operational turnaround with a substantial reduction in net loss and achievement of positive Adjusted EBITDA. While the top-line financial results were previously announced in an 8-K, this filing offers the full context and detailed breakdown.

These legal and regulatory risks present material uncertainties that could significantly impact future operations and financial performance, balancing the positive financial momentum.
