Heartflow surges after strong Q2 growth and higher 2026 outlook

Heartflow, Inc. (HTFL) is up 32.9% today. Here is some analysis on what might have caused this price movement.

Analysis: The most likely catalyst is Heartflow’s second-quarter 2026 earnings release, which showed faster revenue growth, stronger margins, and a meaningful increase to full-year guidance. Investors also appear to be responding to signs that the company’s Plaque product is becoming a larger growth driver alongside its core FFRCT business.

Details:

Heartflow reported second-quarter revenue of $64.1 million, up 48% from a year earlier, with U.S. revenue rising 51% to $59.6 million.

The company lifted full-year 2026 revenue guidance to $246 million to $250 million, up from its prior range of $228 million to $232 million, and nudged expected non-GAAP gross margin to about 82%.

Gross margin reached 83.0% in the quarter, while adjusted EBITDA improved to a loss of $6.7 million from a loss of $10.1 million a year earlier, suggesting improving operating leverage.

Management said growth was supported by higher U.S. FFRCT case volume and rising U.S. Plaque revenue case volume, reinforcing the view that demand is broadening across the platform.
