SAN FRANCISCO, May 3, 2017 -- iRhythm Technologies, Inc. (NASDAQ: IRTC), a leading digital health care solutions company focused on the advancement of cardiac care, today reported financial results for the three months ended March 31, 2017.

First Quarter 2017 Financial Results

• Revenue for the quarter ended March 31, 2017 increased 67% year-over-year to $21.4million

• Gross margin for the first quarter 2017 was 70.4% versus 63.8% in the first quarter of 2016

First Quarter 2017 Business Highlights

• The American College of Cardiology (ACC), the American Heart Association (AHA), and the Heart Rhythm Society (HRS) jointly issued a new guideline that recommends the use of cardiac monitors such as the Zio Service when evaluating patients with syncope (fainting).

• The National Institute for Health and Care Excellence (NICE) in the U.K. issued a publication citing evidence that demonstrates the high diagnostic yield of the company’s Zio Service compared to the Holter monitor.

• The results of a study comparing detection rates of atrial fibrillation between the company's Zio Service and the Holter monitor in patients following stroke was accepted as a late-breaking clinical trial oral presentation at the 3rd European Stroke Organisation Conference, to be held in Prague on May 18, 2017.

"Adoption of our Zio Service continued at a strong pace in the first quarter. While taking a highly disciplined and measured approach to hiring, we made substantial progress expanding our sales organization, and have now nearly completed building out our sales management and support infrastructure.  In addition, we were also successful in expanding reimbursement coverage and contracts with commercial payors to increase patient access,” said Kevin King, CEO. "I am pleased with the growing market penetration of our Zio Service and the positive impact we are making on the early diagnosis and treatment of cardiac arrhythmias.”

First Quarter Financial Results

Revenue for the three months ended March 31, 2017 increased 67% to $21.4 million, from $12.9 million during the same period of the prior year. The increase in revenue was due primarily to increased volume of the Zio Service.   

Gross profit for the first quarter of 2017 was $15.1 million, or 70% gross margin, up from $8.2 million, or 64% gross margin, in the same period of the prior year.

Operating expenses for the first quarter of 2017 were $19.8 million, an increase of 52% compared to the same period of the prior year. The increase in operating expenses was driven primarily by selling, general and administrative expenses used to expand the company’s sales force and support the growth in operations.

Loss from operations for the first quarter of 2017 was $4.7million, compared to $4.9million for the same period of the prior year.

Cash, cash equivalents, short-term investments, and long-term investments totaled $109.4 million as of March 31, 2017.
