SAN FRANCISCO, Nov. 05, 2026 (GLOBE NEWSWIRE) — iRhythm Holdings, Inc. (NASDAQ: IRTC), a leading digital health care company with a mission to create trusted solutions that detect, predict, and prevent disease, today reported financial results for the three months ended September 30, 2026.

Third Quarter 2026 Financial Highlights

• Gross margin of 74.2%, a 310-basis point increase compared to third quarter 2025
• GAAP net loss of $29.9 million, a $24.6 million increase in net loss compared to third quarter 2025
• Adjusted EBITDA and adjusted EBITDA margin of $51.2 million and 23.1%, respectively, a $29.6 million and 1,190-basis point improvement, respectively, compared to third quarter 2025
• Unrestricted cash, cash equivalents, and marketable securities of $560.7 million as of September 30, 2026
• Increased fiscal year 2026 revenue guidance to $890 million to $895 million and adjusted EBITDA margin guidance to 15.5% to 16.0%

Recent Operational Highlights

• Delivered another strong quarter, driven by healthy volume-led revenue growth of Zio Monitor and robust margin expansion, with broad-based momentum across cardiology, primary care, innovative channels and international markets
• Completed the acquisition of VitalConnect on October 5, 2026, broadening our cardiac monitoring portfolio with an immediate FDA-cleared mobile cardiac telemetry offering, advancing our multi-vitals strategy, and expanding our addressable market across the continuum of care
• Published three large-scale real world studies demonstrating product superiority of Zio AT (CAMELOT-ALERT¹), Zio Long-Term Continuous Monitoring (EXCALIBUR²), and improvements in Zio Monitor performance and diagnostic yield compared with Zio XT³ in over 1.7 million total patients
• Submitted FDA 510(k) applications for pediatric use with our Zio Monitor long-term continuous monitoring business
• Closed a new $300 million senior secured revolving credit facility on November 3, 2026, providing additional liquidity to support our long-term growth objectives

“Our third quarter results reflect the continued strength of our core business. Demand for Zio Monitor remains robust, exceeding our expectations in the quarter, driven by volume growth across care settings and channels. We also continued to take meaningful steps forward with significant margin expansion, and consistent execution against our strategic priorities,” said Quentin Blackford, President and Chief Executive Officer of iRhythm. “With the acquisition of VitalConnect now closed, we are encouraged by the early opportunities we see to broaden our capabilities and serve more patients within the ambulatory cardiac monitoring market and across the continuum of care. With an immediate FDA-cleared mobile cardiac telemetry device, we are excited to be able to offer the marketplace a best-in-class MCT portfolio of options. We remain focused on advancing innovation, expanding access to Zio, and investing in the growth initiatives that we believe will create durable value for patients, clinicians, and stockholders.”

Third Quarter 2026 Financial Results
Revenue for the third quarter of 2026 was $221.6 million, up 14.9% from $192.9 million during the same period in 2025. The increase was driven primarily by sustained volume demand across our customer base, reflecting continued strength in our core business and contributions from newer growth channels.

Gross profit for the third quarter of 2026 was $164.5 million, up 20.0% from $137.1 million during the same period in 2025, while gross margin was 74.2%, a 310-basis point improvement compared to the third quarter of 2025. The increase in gross profit was primarily due to increased volume of Zio services, as well as a one-time benefit from tariff refunds of approximately $3.1 million. The increase in gross margin was primarily driven by continued operational efficiencies, product mix, a tariff refund one-time benefit, and disciplined execution.

Operating expenses for the third quarter of 2026 were $197.0 million, compared to $145.6 million for the same period in 2025. Adjusted operating expenses for the third quarter of 2026 were $138.6 million, compared to $141.4 million during the same period in 2025. The decrease in adjusted operating expenses, period over period, reflects a disciplined approach to investment, as we funded key growth initiatives while thoughtfully managing costs across the broader organization.

GAAP net loss for the third quarter of 2026 was $29.9 million, or net loss per diluted share of $0.90, compared with GAAP net loss of $5.2 million, or net loss per diluted share of $0.16, for the same period in 2025. Adjusted net income for the third quarter of 2026 was $27.8 million, or net income per diluted share of $0.82, compared with an adjusted net loss of $2.0 million, or net loss per diluted share of $0.06, for the same period in 2025. The improvement was primarily driven by our revenue growth and operating leverage achieved through implementation of efficiency initiatives.

Unrestricted cash, cash equivalents, and marketable securities were $560.7 million as of September 30, 2026.

2026 Annual Guidance
For the full year 2026, iRhythm expects revenue between $890 million and $895 million, which includes approximately $16 million of expected VitalConnect revenue contribution from the October 5, 2026 acquisition close through year-end. iRhythm also expects adjusted EBITDA margin between 15.5% and 16.0%, inclusive of VitalConnect. iRhythm’s guidance reflects continued volume-led growth and operating leverage while maintaining disciplined investment in innovation and market expansion.

Use of Non-GAAP Financial Measures
We refer to certain financial measures that are not recognized under U.S. generally accepted accounting principles (GAAP) in this press release, including adjusted EBITDA, adjusted EBITDA margin, adjusted net income (loss), adjusted net income (loss) per diluted share, adjusted operating expenses and free cash flow. We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures may be helpful to investors. However, non-GAAP financial measures are presented for supplemental informational purposes only, have limitations as analytical tools, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our disclosure of non-GAAP financial measures as a tool for comparison. See the schedules attached to this press release for additional information and reconciliations of such non-GAAP financial measures. We have not reconciled our adjusted EBITDA margin estimates for full year 2026 because certain items that impact these figures are uncertain or out of our control and cannot be reasonably predicted. Accordingly, a reconciliation of adjusted EBITDA margin estimates is not available without unreasonable effort.

Adjusted EBITDA is defined as net income (loss) before income tax provision, depreciation and amortization, interest expense, and interest income and as further adjusted for stock-based compensation expense, changes in fair value of strategic investments, impairment charges, business transformation costs, certain intellectual property litigation expenses, certain litigation settlements (net of expected insurance recoveries), costs related to the cybersecurity incident (net of expected insurance recoveries), and loss on extinguishment of debt. Business transformation costs include costs associated with professional services, employee termination and relocation, third-party merger and acquisition, integration, and other costs to augment and restructure the organization, inclusive of both outsourced and offshore resources.

Forward-Looking Statements
This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. An investor can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as ‘anticipate’, ‘estimate’, ‘expect’, ‘intend’, ‘will’, ‘project’, ‘plan’, ‘believe’, ‘target’ and other words and terms of similar meaning in connection with any discussion of future actions or operating or financial performance. In particular, these statements include statements regarding our financial guidance, volume growth and margin expansion, market opportunity, ability to penetrate the market, expansion into new health programs, international market expansion, anticipated productivity and quality improvements, anticipated demand for our products and services and our expectations for growth, and statements regarding the anticipated benefits of the VitalConnect acquisition, including our ability to broaden our capabilities, advance our multi-vitals strategy, expand our addressable market and serve more patients across the continuum of care, our ability to create durable, long-term value for patients, clinicians and stockholders; and the anticipated benefits of our revolving credit facility. Such statements are based on current assumptions that involve risks and uncertainties that could cause actual outcomes and results to differ materially. These risks and uncertainties, many of which are beyond our control, include, but are not limited to: intense competition in the markets we compete in; fluctuations in our operating results; our ability to successfully integrate any acquisitions or strategic investments; risks associated with managing our growth; future U.S. and global political, competitive, reimbursement and regulatory conditions, including changing trade and tariff policies; geopolitical conflicts and tensions; distribution and supply chain disruptions and cost increases; new product and service introductions and the market acceptance of those products and services; expected pricing environment; intellectual property rights; litigation; financial market conditions; the execution and effect of our business strategy; and future business decisions made by us and our competitors. Additional risks are described in the section entitled “Risk Factors” and elsewhere in our filings made with the Securities and Exchange Commission, including our Quarterly Report on Form 10-Q expected to be filed on or about November 5, 2026. These forward-looking statements speak only as of the date of this press release and should not be unduly relied upon. iRhythm undertakes no obligation to update them except as required by law.
