"We delivered a strong start to 2026, with continued revenue growth reflecting durable demand for our platform and increasing adoption across multiple care settings," said Quentin Blackford, President and Chief Executive Officer of iRhythm. "We are increasingly diversified across channels, with meaningful contributions from Zio monitor, Zio AT, innovative partnerships, and international markets. As we advance our AI-enabled capabilities and expand into earlier detection, we believe we are unlocking a significantly larger opportunity to improve patient outcomes while providing an integrated solution that lowers the total cost of cardiac care."

First Quarter 2026 Financial Results

Revenue for the first quarter of 2026 was $199.4 million, up 25.7% from $158.7 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 first quarter of 2026 was $141.4 million, up 29.4% from $109.2 million during the same period in 2025, while gross margin was 70.9%, a 210-basis point improvement compared to first quarter 2025. The increase in gross profit was primarily due to increased volume of Zio services. The increase in gross margin was primarily driven by continued operational efficiencies, as well as scale benefits from higher volumes.

Operating expenses for the first quarter of 2026 were $157.5 million, compared to $141.8 million for the same period in 2025. Adjusted operating expenses for the first quarter of 2026 were $153.5 million, compared to $140.4 million during the same period in 2025. The increase in adjusted operating expenses, period over period, was driven by an increase in volume-related costs to serve, litigation-related expenses and investments to drive future revenue growth.

Net loss for the first quarter of 2026 was $13.9 million, or a net loss of $0.43 per diluted share, compared with net loss of $30.7 million, or net loss of $0.97 per diluted share, for the same period in 2025. Adjusted net loss for the first quarter of 2026 was $11.3 million, or net loss of $0.35 per diluted share, compared with an adjusted net loss of $30.3 million, or net loss of $0.95 per diluted share, for the same period in 2025. The decrease in net loss was primarily driven by our revenue growth and operating leverage achieved through implementation of efficiency initiatives.

Unrestricted cash, cash equivalents, and marketable securities were $549.6 million as of March 31, 2026.

2026 Annual Guidance

For the full year 2026, iRhythm expects revenue between $875 million and $885 million and adjusted EBITDA margin between 12% and 13%, reflecting continued volume-led growth, gross margin expansion, 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 loss, adjusted net loss per 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. 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 operating expenses and 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 operating expenses and adjusted EBITDA estimates is not available without unreasonable effort.

Adjusted EBITDA excludes non-cash operating charges for stock-based compensation expense, changes in fair value of strategic investments, impairment and restructuring charges, business transformation costs, certain intellectual property litigation expenses and settlements, 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.

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.
