**iRhythm Holdings Announces First Quarter 2026 Financial Results**

**SAN FRANCISCO, April 30, 2026** -- <u>iRhythm Holdings, Inc.</u> (NASDAQ: IRTC), a leading digital health care company focused on creating trusted solutions that detect, predict, and prevent disease, today reported financial results for the three months ended March 31, 2026.

**First Quarter 2026 Financial Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue of $199.4 million, a 25.7% increase compared to first quarter 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin of 70.9%, a 210-basis point increase compared to first quarter 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net loss of $13.9 million, a $16.8 million improvement compared to first quarter 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA and adjusted EBITDA margin of $14.1 million and 7.1%, respectively, a $16.7 million and 880-basis point improvement, respectively, compared to first quarter 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Unrestricted cash, cash equivalents, and marketable securities of $549.6 million as of March 31, 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased fiscal year 2026 revenue guidance to $875 million to $885 million and adjusted EBITDA margin to 12.0% to 13.0%

**Recent Operational Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Delivered another strong quarter, demonstrated by robust volume led revenue growth and expanded margins, with continued momentum across cardiology, primary care, innovative channels, and international markets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Presented data at ACC and HRS further demonstrating the benefits of iRhythm's Zio® ambulatory ECG portfolio across multiple patient populations as company launches new digital education platform

"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.

**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.

**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 financial guidance, 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 expectations for growth. 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 risks described in the section entitled "Risk Factors" and elsewhere in our filings made with the Securities and Exchange Commission, including those on the Form 10-Q expected to be filed on or about April 30, 2026. These forward-looking statements speak only as of the date hereof and should not be unduly relied upon. iRhythm disclaims any obligation to update these forward-looking statements.
