Heartflow, Inc. – 2025-11-14 - increase Confidence 7/10

HFLO – increase in Days/Weeks

Heartflow reported Q3 2025 revenue of $46.3 million, a 41% year-over-year surge, just days after hosting its earnings call on November 12, 2025. The stock, trading at $27.98, is reacting to robust commercial adoption and a raised full-year revenue outlook.

Why This Matters

Heartflow is scaling rapidly in the high-growth AI-driven healthcare diagnostics space, with revenue accelerating despite continued losses—demonstrating market acceptance and pricing power. The recent earnings release, strong gross margin expansion to 76.5%, and a healthy $291.2 million cash balance provide near-term confidence in execution, especially as institutional holders like Baillie Gifford and FMR remain anchored, signaling long-term conviction.

Key Insights

• Revenue Growth: Revenue +41% YoY to $46.3M in Q3 2025, with full-year 2025 guidance raised to $173M–$173.5M (+37.5% YoY)
• News Impact: Q3 results exceeded expectations, with improving gross margins and strong patient adoption (500,000+ cases) acting as positive catalysts
• Risk/Offset: Negative free cash flow (-$73.36M TTM) and net losses ($50.9M in Q3) remain, though non-GAAP losses are narrowing

Practical Implications

• Bull Case: Sustained revenue acceleration and AI healthcare tailwinds could drive 10–15% upside toward $30–$32 in coming weeks
• Bear Case: Continued GAAP losses and low institutional ownership (13.93%) may limit momentum if broader tech multiples compress
• Confidence: 7/10 – Strong top-line momentum and recent positive earnings reaction support near-term gain

Prediction: increase
