On this page of Benford's Law Stocks.com we present our study of Heartflow Inc. — ticker symbol HTFL. SEC filings have been screened by our Benford's Law software, for quarterly 10Q and annual 10K filings from 9/19/2025 to 8/13/2026 for Heartflow Inc. under CIK number 0001464521. For filings made in XBRL (eXtensible Business Reporting Language) format, our algorithm extracts all "tagged" numbers presented by the company; for any non-XBRL filings our algorithm uses its own interal set of rules to extract what it believes to be numbers as found throughout the filings. The format found for each filing is presented below together with the results for HTFL, with the percentage of found numbers beginning with each digit (1's, 2's, 3's, 4's, 5's, 6's, 7's, 8's, and 9's) charted against the "normal" range observed throughout our coverage universe, as well as the "normal" range for Heartflow Inc. based on the past HTFL filings our system processed in the past.

Normal count compared to other filers, falling within the middle 50%. At this number count, it would take about 8 numbers to move any given column by a full percentage point.
92

Starting from a possible score of 100, we made the following score deductions:
 • The 4's percentage was higher than the 3's percentage, increasing the penalty multiplier.
 • We deducted points (includes the impact of penalty multiplier) upon observing the 4's percentage was above the typical coverage universe range.
 • We deducted point upon observing the 6's percentage was above the typical coverage universe range.
 • The 8's percentage was higher than the 7's percentage, increasing the penalty multiplier.
 • However, because we observed that the company's shares outstanding count begins with the digit 8, we canceled the penalty multiplier.
 • We deducted points upon observing the 8's percentage was above the typical coverage universe range.

Check our work! We provide our Heartflow Inc. Benford's Law analysis for informational purposes only, and our software should be expected to make mistakes and contain errors (nothing you see on this website should be relied upon for any decision-making without first repeating the analysis yourself independently), and so below we present to you all of the numbers our system detected, for the HTFL filing above. This way, you can open the filing on your own and compare what you see below against what you yourself find. This can also be helpful for exploring any columns in particular that caught your eye.

While the above HTFL 10Q Filed 8/13/2026 is interesting in isolation, we have found that it is also useful to take a look at older Heartflow Inc. filings processed by our Benford's Law Stocks algorithm, to see how the company's filings "typically look" on a Benford's Law analysis. Below we repeat the 10Q Filed 8/13/2026 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical HTFL 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
