Ticker impact
Heartflow shares jumped after the company boosted full-year revenue targets to $246M-$250M and raised gross margin guidance.
Likely continued upside bias while traders digest the raised revenue growth range and higher gross margin target.
The article cites a specific, same-day catalyst: full-year revenue guidance raised from 29%-32% to 40%-42% growth, plus adjusted gross margin target increased to 82% from 81%.
Market effects
Positive read-through for AI-enabled medical diagnostics and non-invasive cardiac imaging demand narratives.
