What this transaction means for investors
Hedge fund Capricorn Investment Group’s purchase of 1.7 million shares in HeartFlow is a noteworthy event. The buy represents a new position for Capricorn, and since the fund only had seven holdings valued at over $825 million at the end of 2025, it is selective about the stocks it chooses.
HeartFlow shares went public in August of 2025, so limited history is available in terms of its financial performance. Shares hit a 52-week high of $41.22 last October, but have dropped in 2026.
The company is doing great. In 2025, HeartFlow generated $176.0 million in revenue, a strong 40% year-over-year increase.
HeartFlow is not profitable, however. It ended the fourth quarter with a net loss of $24.4 million, but that is a drop from the previous year’s loss of $33 million. This indicates the company is working to reduce costs.
With the decline in its share price, HeartFlow’s price-to-sales ratio of 12 is near a low point since its IPO. This suggests now is a good time to pick up the stock.
Since it has a brief history as a public company, HeartFlow is still a risky investment at this time, so this is a stock for investors with a high risk tolerance.
