HeartFlow (HTFL) Stock Jumps +92.9% in 30 Days on Strong Q2 Results
Key Takeaways
- HeartFlow shares rose approximately 92.9% over the trailing 30 days, climbing from about $25.37 to roughly $48.94.
- The rally was driven by second-quarter 2026 results that beat expectations and a meaningful increase to full-year revenue guidance.
- Several sell-side firms raised price targets following the report, reinforcing positive sentiment toward the stock.
- The company remains unprofitable, so growth execution and continued adoption of its Plaque Analysis product remain central to the investment case.

HeartFlow (HTFL) Stock Price Performance: Last 30 Days vs. Quarter
Over the last 30 days, HTFL advanced roughly 92.9%, rising from a closing price near $25.37 in late July to about $48.94 by late August. Most of that move occurred in a matter of days after the company reported quarterly results, with shares jumping more than 35% in a single session and continuing to trade near 52-week highs afterward.
The quarterly picture tells a similar but more volatile story. Roughly three months earlier, the stock traded near $28, meaning it has gained on the order of 72% over the period. That broader trend was not linear: shares declined through much of July into the low-to-mid $20s before rebounding sharply once second-quarter results and revised guidance reset investor expectations.
What Drove HTFL Stock Price in the Last 30 Days
The primary catalyst was HeartFlow's second-quarter 2026 earnings report. Revenue rose 48% year over year to approximately $64.1 million, ahead of the consensus estimate near $56.6 million, and adjusted loss per share of $0.07 was narrower than the roughly $0.13 loss analysts had expected. Gross margin reached record levels, expanding to 83.0% on a GAAP basis and 83.3% on a non-GAAP basis.
Management also raised its full-year 2026 revenue guidance to between $246 million and $250 million, up from a prior range of $228 million to $232 million, implying roughly 40% to 42% growth, and lifted its full-year gross margin target. Analysts responded by raising price targets—Stifel moved to $45 from $40 with a Buy rating, JPMorgan raised its target to $45 from $35 with an Overweight rating, and Wells Fargo increased its target to $39 from $37. William Blair's Brandon Vazquez maintained an Outperform rating, noting the guidance increase was roughly twice the size of the earnings beat. From what I see, this level of analyst support adds meaningful weight to the recent move.
What Drove HTFL Stock Performance Over the Last Quarter
Beyond the immediate earnings reaction, the stock's three-month advance reflects a broader narrative of accelerating adoption of AI-enabled cardiac diagnostics. HeartFlow's core FFRCT business has remained durable, while Plaque Analysis has emerged as a fast-growing second revenue engine following expanded reimbursement coverage. The company also launched PCI Navigator, an AI-driven pre-procedure planning tool for interventional cardiologists, and has pointed to a substantially under-penetrated CCTA market as a source of continued growth.
Institutional participation has also increased. According to third-party data, the number of hedge funds holding HeartFlow shares rose from 16 to 25 between consecutive quarters, with combined holdings growing by more than half. At the same time, the stock remains unprofitable, and valuation has expanded alongside the rally, leaving the shares sensitive to any shortfall in adoption or reimbursement trends.
HTFL Stock Forecast Drivers: What Investors Should Watch Next
Looking ahead, investors are likely to focus on the pace of Plaque Analysis adoption, including the company's progress toward its target of roughly 1,200 active sites, and on whether FFRCT case volumes sustain their current growth. Reimbursement developments, new clinical data, and updates to full-year guidance will also matter, as will the company's path toward narrowing operating losses and reaching cash-flow profitability. Because the stock has re-rated sharply, execution against the raised revenue outlook and continued gross-margin expansion will be closely monitored, alongside any signs that adoption is slowing or that valuation has outrun fundamentals. I’m watching this closely as the next few quarters will test whether the momentum holds.
