Auditor Change Feed: free sample (Tensorust LLC)
Every public company auditor dismissal and resignation filed on Form 8-K since November 2025, with disagreements and material weaknesses flagged.
Headline: When a public company's auditor resigns or is dismissed, the 8-K Item 4.01 says so within four business days, and the resignations are the warning sign most readers miss.
This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 584 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/sec-auditor-changes/.

Method and limits
EDGAR full-text search for 8-K and 8-K/A filings mentioning Item 4.01 or its title; keep only filings whose EDGAR item list includes 4.01. Fetch each document and read the Item 4.01 section for dismissal, resignation, disagreement, reportable event and going-concern language. Audit firm names are pattern-matched on legal-form endings and placed as departing or new by context. Tickers from the SEC ticker file; federal awards joined from USAspending in the Tensorust Ontology.
Not an audit opinion or advice. Firm names and change type are machine-parsed and can be wrong; each row links to the filing.
