• HTFL -1.27%

Heartflow Inc. (NASDAQ:HTFL) climbed by 46 percent week-on-week, making it the fourth-highest gainer on the stock market last week, thanks to its strong revenue performance that helped bolster its growth outlook for the full-year period.

In an updated report during the week, the listed firm said that it grew its revenues by 48 percent in the second quarter of the year to $64.08 million from $43.2 million in the same period last year, on the back of strong revenue volume growth from its US Fractional Flow Reserve business, coupled with an increase in total US Plaque revenue case volume.

However, it widened its net loss by 70.6 percent to $15.7 million from $9.2 million, amid higher losses before provision for income taxes.

In the first half of the year, revenues increased by 45 percent to $116.67 million from $80.63 million, while net loss inched up by 3.6 percent to $43.1 million from $41.5 million year-on-year.

Higher 2026 Growth Outlook

Heartflow Inc. (NASDAQ:HTFL) posted a highly optimistic outlook for the full-year period, with revenue growth now expected to grow by 40 to 42 percent to a range of $246 million to $250 million. It previously expected revenues to jump by 29 to 32 percent to a range of $228 million to $232 million.

"The second quarter reflects the growing strength of Heartflow's category leadership and unique AI technology platform for identifying, diagnosing, managing, and treating coronary artery disease," President and CEO John Farquhar said.

"The CCTA market for detecting CAD continues to grow rapidly and remains significantly under-penetrated, providing a strong backdrop for continued growth. Our FFR business remains strong and durable, while Plaque is rapidly emerging as a meaningful second growth engine—helping us win new accounts, deepen physician utilization and expand the value of the Heartflow platform for our customers. At the same time, record gross margin and improving operating leverage demonstrate the increasing scalability of our model, giving us greater confidence in long-term, profitable growth."
