PCAOB Publishes New Edition of Data Points on Financial Restatements and Auditor Turnover

WASHINGTON, Oct. 15, 2025

Today, the PCAOB released a new edition of Data Points: “Financial Restatements and Auditor Turnover.”

From 2005 to 2024, Big R financial restatements occurred at a rate of around 3% per year. (A Big R restatement refers to a restatement disclosed in an SEC Form 8-K, Item 4.02.) On average, just under 30% of these restatements followed an auditor change in the previous year. As a point of reference, the average annual auditor-change rate across the broader population, which includes companies without Big R restatements, was 11%.

Prepared by the PCAOB’s the Office of Economic and Risk Analysis (OERA), the Data Points series presents concise, data-driven insights relevant to audits. Each edition of Data Points offer neutral, factual information drawn from PCAOB datasets and other available sources.
