About TickerGraveyard

TickerGraveyard is the structured archive of public-company tickers that no longer trade. Every record traces back to a primary regulatory source. Coverage today is US-listed securities — SEC EDGAR Form 25 (notification of removal from listing), Form 15 (deregistration), 8-K disclosures, FINRA OTCE Daily List entries, and bankruptcy court dockets — with additional global jurisdictions (Hong Kong, London, Tokyo, Toronto) rolling out next.

Methodology

For each delisted ticker we extract three layers of structured data:

  1. Identity: symbol, exchange, CIK, CUSIP, FIGI, IPO date, delisting date, final status, and reason category.
  2. Outcome: what a holder of one common share received as final consideration (cash, acquirer stock, escrow, OTC residual value, or zero recovery). Each outcome carries a confidence rating tied to source filing density.
  3. Pre-mortem signals: observable warning signs in the 24 months preceding delisting — Reg SHO threshold listings, sub-$1 trading streaks, auditor changes, going-concern opinions, abnormal insider selling, listing deficiency notices, late 10-K filings, and financial restatements.

AI transparency

Narrative summaries on each ticker page (Hero summary, Post-Mortem Analysis, Lessons for Today's Investors) are AI-assisted summaries of the source filings linked at the bottom of every page. The structured data — outcomes, signals, dates, identifiers — is extracted directly from filings and not inferred.

We follow an explicit AI content declaration policy. Every page carries a machine-readable ai-content-declaration meta tag, an llms.txt directive at the site root, and JSON-LD ClaimReview markup on atomic factual claims with a verifiable SEC source URL.

Disclaimer

All content is provided for informational and educational purposes only and is not investment advice, a solicitation to buy or sell securities, or a recommendation of any kind. Past delisting events and shareholder outcomes are not predictive of future results for any other security.

If you find an error in our records, the canonical source is always the SEC filing or regulatory notice linked in the page's Source Filings section.
