"We achieved record new account onboarding, with balanced volume contributions across multiple channels, particularly in risk-bearing, primary care settings where Zio's value as a population health management tool has resonated strongly. Throughout 2024, we enhanced our quality systems, improved customer experience through EHR integration and innovative product launches, expanded into multiple international markets, and secured strategic technology licensing agreements to advance connected patient care. Our commitment to operational discipline has yielded positive cash flow for three consecutive quarters, while our extensive scientific publications have further validated our approach. Looking ahead, we remain focused on delivering a best-in-class quality system while creating shareholder value through our strategies of expanding our core U.S. market presence, accelerating international growth, advancing product innovation, and further advancing operational efficiencies. As we scale the Zio platform globally, we're uniquely positioned to shape the future of healthcare while driving value for patients, physicians, health systems, and shareholders."

Fourth Quarter 2024 Financial Results
Revenue for the three months ended December 31, 2024, increased 24.0% to $164.3 million, from $132.5 million during the same period in 2023. The increase was primarily attributable to increases in the volume of Zio Services resulting from increased demand, partially offset by a slight decline in average selling price.

Gross profit for the fourth quarter of 2024 was $115.1 million, up from $87.4 million during the same period in 2023, while gross margins were 70.0% as compared to 66.0% during the same period in 2023. The improvement in gross margin was primarily driven by operational efficiencies leading to lower costs per unit to serve a higher volume of patients compared to the prior year.

Operating expenses for the fourth quarter of 2024 were $119.2 million, compared to $126.6 million for the same period in 2023 and $151.8 million in the third quarter of 2024. The fourth quarter of 2023 included $11.1 million of higher operating expenses due to an impairment charge for our right-of-use capitalized leased asset value of our San Francisco office. The decrease in operating expenses compared to the third quarter 2024 was due primarily to a $32.1 million charge in the third quarter of 2024 for in-process research and development charges related to technology license consideration.

Net loss for the fourth quarter of 2024 was $1.3 million, or a diluted loss of $0.04 per share, compared with net loss of $38.7 million, or a diluted loss of $1.26 per share, for the same period in 2023.

Full Year 2024 Financial Results
Revenue for the year ended December 31, 2024, increased 20.1% to $591.8 million, from $492.7 million in 2023. The increase in revenue was primarily due to increased volume of Zio services provided as a result of increased demand.

Gross profit for the year was $407.5 million, up from $331.8 million in 2023, while gross margin was 68.9%, an improvement from 67.3% in 2023. The improvement in gross margin was primarily driven by operational efficiencies leading to lower costs per unit to serve a higher volume of patients compared to the prior year.

Operating expenses for the year were $523.0 million, an increase of 14.5% compared to 2023. The increase was mainly due to acquired IPR&D expenses related to license consideration, along with an increase in headcount-related costs and professional fees to support the growth in our business.

Net loss for 2024 was $113.3 million, or a diluted loss of $3.63 per share, compared with net loss of $123.4 million, or a diluted loss of $4.04 per share in 2023.

Cash, cash equivalents and marketable securities were $535.6 million as of December 31, 2024.

2025 Guidance
iRhythm projects revenue for the full year 2025 between $675 million to $685 million. Adjusted EBITDA margin for the full year 2025 is expected to range from approximately 7.0% to 8.0% of revenues.

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 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, 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.
