On this page of Benford's Law Stocks.com we present our study of MASIMO CORP — ticker symbol MASI. SEC filings have been screened by our Benford's Law software, for quarterly 10Q and annual 10K filings from 2/23/2021 to 11/4/2025 for MASIMO CORP under CIK number 0000937556. 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 MASI, 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 MASIMO CORP based on the past MASI filings our system processed in the past.

1251
High count compared to other filers, with MASI falling in the highest quartile of filers. At this number count, it would take about 13 numbers to move any given column by a full percentage point.
96

Starting from a possible score of 100, we made the following score deductions:
 • We deducted point upon observing the 1's percentage was above the typical coverage universe range.
 • We deducted point upon observing the 3's percentage was below the typical coverage universe range.
 • The 5's percentage was higher than the 4's percentage, increasing the penalty multiplier.
 • However, because we observed that the company's shares outstanding count begins with the digit 5, we canceled the penalty multiplier.
 • We deducted point upon observing the 5's percentage was above the typical coverage universe range.
 • We deducted point upon observing the 8's percentage was below the company's typical historical range.
 • The 9's percentage was higher than the 8's percentage, increasing the penalty multiplier.

Check our work! We provide our MASIMO CORP 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 MASI 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 MASI 10Q Filed 11/4/2025 is interesting in isolation, we have found that it is also useful to take a look at older MASIMO CORP 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 11/4/2025 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical MASI 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
