On this page of Benford's Law Stocks.com we present our study of PROTHENA CORP PUBLIC LTD CO — ticker symbol PRTA. SEC filings have been screened by our Benford's Law software, for quarterly 10Q and annual 10K filings from 11/4/2021 to 8/6/2026 for PROTHENA CORP PUBLIC LTD CO under CIK number 0001559053. 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 PRTA, 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 PROTHENA CORP PUBLIC LTD CO based on the past PRTA filings our system processed in the past.

95

Starting from a possible score of 100, we made the following score deductions:
 • 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 points upon observing the 5's percentage was above the typical coverage universe range.
 • We deducted point upon observing the 6's percentage was below the company's typical historical range.
 • The 7's percentage was higher than the 6's percentage, increasing the penalty multiplier.
 • We deducted points (includes the impact of penalty multiplier) upon observing the 7's percentage was above the typical coverage universe range.

While the above PRTA 10Q Filed 8/6/2026 is interesting in isolation, we have found that it is also useful to take a look at older PROTHENA CORP PUBLIC LTD CO 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 8/6/2026 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical PRTA 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
