SAN FRANCISCO, May 01, 2025 (GLOBE NEWSWIRE) -- iRhythm Technologies, Inc. (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, 2025.
First Quarter 2025 Financial Highlights
Revenue of $158.7 million, a 20.3% increase compared to first quarter 2024
Gross margin of 68.8%, a 250-basis point increase compared to first quarter 2024
Unrestricted cash, cash equivalents, and marketable securities of $520.6 million as of March 31, 2025
Increased fiscal year 2025 guidance for revenue and adjusted EBITDA margin
Recent Operational Highlights
Strong quarterly revenue unit volume driven by momentum from innovative value-based care accounts as well as demand from Zio AT in the United States and record demand in the United Kingdom
Expanded global reach with commercial launch of Zio monitor in Japan, highlighting our continued commitment to bringing our innovative digital healthcare solutions to millions of people worldwide
As presented at ACC.25, two large real-world studies in over one million patients revealed that short-term, Holter-duration monitoring frequently misses actionable arrhythmias - 64% of daily-symptom patients with actionable arrhythmias went undetected in the first 48 hours - and that patient-reported symptoms are an unreliable predictor of arrhythmic events1,2
AVALON study recently presented at Heart Rhythm Society found that the Zio® long-term continuous monitor (LTCM) associated with higher adjusted odds of arrhythmia detection, fewer repeat tests, and reduced likelihood of cardiovascular events compared to other modalities and LTCM brands in the follow-up year3
"The first quarter of 2025 demonstrated continued commercial momentum, with revenue growth exceeding 20% year-over-year, driven by upstream expansion in the patient care pathway and strength in our Zio AT business," said Quentin Blackford, President and Chief Executive Officer of iRhythm. "We've seen increasing demand from recently opened accounts while also driving penetration within innovative, value-based care and risk-bearing entities. With our recent commercial launch in Japan, we are now actively driving physician and health system awareness of Zio in six markets outside the U.S., contributing to our milestone of 10 million patient reports posted since iRhythm's inception. With strong execution across multiple growth levers and additional catalysts on the horizon, we are more excited than ever as we continue to enable the earlier diagnosis of cardiac arrhythmias, opening the potential to reduce costs and deliver meaningful value for patients, our customers, healthcare systems, and shareholders."
First Quarter Financial Results Revenue for the first quarter of 2025 was $158.7 million, up 20.3% from $131.9 million during the same period in 2024. The increase was driven by growth in demand for Zio services.
Gross profit for the first quarter of 2025 was $109.2 million, up 24.8% from $87.5 million during the same period in 2024, while gross margin was 68.8%, up from 66.3% during the same period in 2024. The increase in gross profit was primarily due to increased volume of Zio services provided due to higher demand. The increase in gross margin was primarily due to volume leverage as well as operational efficiencies, partially offset by an increased blended cost per unit from a higher Zio AT product mix.
Operating expenses for the first quarter of 2025 were $141.8 million, compared to $125.7 million for the same period in 2024. Adjusted operating expenses for the first quarter of 2025 were $140.4 million, compared to $125.7 million during the same period in 2024. The increase in adjusted operating expenses was primarily driven by funding of innovation and incremental costs to serve a growing volume of patients globally.
Net loss for the first quarter of 2025 was $30.7 million, or a diluted loss of $0.97 per share, compared with net loss of $45.7 million, or a diluted loss of $1.47 per share, for the same period in 2024. Adjusted net loss for the first quarter of 2025 was $30.3 million, or a diluted loss of $0.95 per share, compared with an adjusted net loss of $38.1 million, or a diluted loss of $1.23 per share, for the same period in 2024. 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 $520.6 million as of March 31, 2025.
2025 Annual Guidance iRhythm projects revenue for the full year 2025 between $690 million to $700 million. Adjusted EBITDA margin for the full year 2025 is expected to range from approximately 7.5% to 8.5% of revenues.

Reclassifications Certain prior period amounts have been reclassified to conform to the current year presentation. These reclassifications have no impact on previously reported results of operations or financial position.
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 net loss, adjusted net loss per share and adjusted operating expenses. 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 2025 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.
Beginning in the first quarter of 2025, we have excluded third-party attorneys' fees and expenses associated with patent litigation brought against the Company by Welch Allyn, Inc. and Bardy Diagnostics, Inc., subsidiaries of Baxter International, Inc. Factors we considered in arriving at this determination to exclude these patent litigation costs from our non-GAAP financial measures include frequency and complexity of the patent litigation, the counterparty involved, and the expected magnitude of patent litigation costs for this matter.
