On this page of Benford's Law Stocks.com we present our study of TANDEM DIABETES CARE INC — ticker symbol TNDM.

While the above TNDM 10K Filed 2/26/2025 is interesting in isolation, we have found that it is also useful to take a look at older TANDEM DIABETES CARE 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 10K Filed 2/26/2025 but instead of the chart comparing against the typical company across our coverage universe, below we show the same chart compared against the typical TNDM 10Q and 10K filings that we have processed historically. This is followed by similar charts for each of those historical filings.
