On this page of Benford's Law Stocks.com we present our study of ARROWHEAD PHARMACEUTICALS, INC. — ticker symbol ARWR. SEC filings have been screened by our Benford's Law software, for quarterly 10Q and annual 10K filings from 5/4/2021 to 2/5/2026 for ARROWHEAD PHARMACEUTICALS, INC. under CIK number 0000879407. 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 ARWR, 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 ARROWHEAD PHARMACEUTICALS, INC. based on the past ARWR filings our system processed in the past.

While the above ARWR 10Q Filed 2/5/2026 is interesting in isolation, we have found that it is also useful to take a look at older ARROWHEAD PHARMACEUTICALS, 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 2/5/2026 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical ARWR 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
