iRhythm Technologies 2025 Q3 Earnings Strong Revenue Beat and Narrowed Losses

iRhythm Technologies (IRTC) reported Q3 2025 earnings that exceeded revenue estimates by 4.6% and significantly narrowed losses year-over-year. The company raised full-year revenue guidance to $735–$740 million, reflecting improved operational performance and demand for its cardiac monitoring solutions.

Revenue

Total revenue surged 30.7% year-over-year to $192.88 million, driven by robust demand across all customer segments. Contracted third-party payors contributed $99.01 million, while Centers for Medicare and Medicaid accounted for $47.56 million. Healthcare institutions added $32.79 million, and non-contracted third-party payors generated $13.52 million, completing the revenue breakdown. The performance underscores the scalability of iRhythm’s platform and strong adoption of its Zio AT and Zio Monitor products.

Earnings/Net Income

The company narrowed its per-share loss to $0.16 in Q3 2025 from $1.48 in Q3 2024, representing an 89.2% improvement. Net losses also declined by 88.7% to $5.21 million from $46.18 million in the prior-year period. Despite these improvements, iRhythm has sustained losses for 10 consecutive years in this quarter, highlighting ongoing financial challenges. This progress, however, reflects operational efficiency gains and margin expansion.

Post-Earnings Price Action Review

The stock surged 3.2% on the day of the earnings release, closing at $184.12, and reached a 52-week high of $190.86 shortly afterward. Analysts from BTIG, Canaccord, and Needham raised price targets, reflecting optimism about the company’s revenue growth and margin expansion. Over a 30-day holding period, the stock gained 1.7%, closing at $187.30. While the immediate reaction was positive, risks such as FDA delays for the Zio MCT device and a high price-to-book ratio (56.5x) could temper long-term momentum. The strategy of buying on revenue beats appears profitable in this instance but requires careful consideration of regulatory and valuation risks. <visualization dataurl="https://cdn.ainvest.com/news/visual/visual_components/viz_fuw4c75q.json"></visualization>
