While the above CSGP 10Q Filed 7/29/2026 is interesting in isolation, we have found that it is also useful to take a look at older COSTAR GROUP, 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 7/29/2026 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical CSGP 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
