SEC Delisting & Deregistration Tracker — Form 25 & 15

Every SEC exchange delisting and deregistration — Form 25-NSE, 25, and 15-12B — with company, ticker, and filing date, delivered as pay-per-record JSON instead of a Bloomberg Terminal seat.

When a company comes off an exchange, a quiet but consequential filing hits EDGAR: a Form 25 (the exchange's notification of delisting), a Form 25-NSE, or a Form 15-12B (the company's certification that it is deregistering and ending its reporting obligations). For index providers, ETF rebalancers, and risk and compliance teams, these filings are the authoritative signal that a ticker is going dark. Miss them and you carry a dead security in your index, your basket, or your risk model.

This actor tracks those filings as they appear on SEC EDGAR and returns each one as a structured record: company name, ticker, form type, filed date, and a direct link to the filing document. It is a scrubbing feed for dead and dying tickers — pull it daily and you have a continuously refreshed list of companies leaving the public markets.

Why use this

The information is public on EDGAR, but EDGAR is built for one-filing-at-a-time retrieval, not for "give me every delisting and deregistration in the last 30 days as a flat file." The platforms that do package this cleanly — a Bloomberg Terminal, primarily — bundle it inside a seat licence that runs roughly $24,000 a year and locks the data behind a terminal you cannot easily pipe into your own systems.

This actor gives you the delisting feed as queryable JSON, pay-per-result, with no seat and no commitment. You pass a date window (or a look-back in days), optionally narrow to a specific form set or a keyword, and get back clean records ready to drop into your index-maintenance pipeline, your compliance scrub, or your warehouse.

• Purpose-built form set. The default forms filter targets exactly the delisting and deregistration forms (25-NSE, 25, 15-12B) — you are not sifting the whole EDGAR firehose.
• Flexible date control. Use daysBack for a rolling window or startDate/endDate for a fixed range, so the same actor serves both a daily scrub and a historical backfill.
• Direct document links. Every record carries documentUrl, so an analyst can jump straight to the source filing for verification.

What you get

Each record returned by the actor is one delisting or deregistration filing, in flat JSON:

• companyName — the filer's company name
• ticker — the company's ticker symbol (where available)
• cik — the filer's SEC Central Index Key
• formType — the SEC form (25-NSE, 25, 15-12B, etc.)
• filedDate — the date the form was filed with the SEC
• accessionNumber — unique EDGAR accession ID for the filing
• primaryDocument — filename of the primary filing document
• documentUrl — a direct link to the filing document on EDGAR
• filingIndexUrl — link to the EDGAR filing index folder

The schema is stable and additive — safe to load into your index-maintenance or compliance pipeline and refresh daily.

Use cases

• Index maintenance. Pull the last day's delistings and deregistrations and scrub matching tickers from your index before the next reconstitution — the canonical "remove dead constituents" job for an index provider.
• ETF rebalancing. Cross-check delisting filings against your fund's holdings so a delisted name is flagged for removal ahead of a rebalance rather than discovered after settlement breaks.
• Risk and compliance ticker scrubbing. Feed the feed into your security master to retire dead tickers, preventing stale identifiers from polluting risk reports and reconciliations.
• Distressed and event-driven research. A Form 25 or 15-12B is often the tail end of a bankruptcy, going-private, or going-dark event — track them to map the full lifecycle of distressed names.
• Data-vendor reconciliation. Use the feed as an independent check against your primary market-data vendor's delisting flags, catching gaps or timing differences.
• Going-dark monitoring. Watch Form 15-12B specifically to catch companies voluntarily ending their reporting obligations — a signal for fixed-income and private-credit teams holding their debt.
• Audit trail for security retirement. Keep the documentUrl for each retired ticker as a documented, source-linked reason for removal in your compliance records.

Sample output

{
"companyName":"Example Holdings Corp",
"ticker":"EXHC",
"cik":"0001234567",
"formType":"25-NSE",
"filedDate":"2026-06-18",
"accessionNumber":"0001234567-26-000045",
"primaryDocument":"form25.htm",
"documentUrl":"https://www.sec.gov/Archives/edgar/data/1234567/000123456726000045/form25.htm",
"filingIndexUrl":"https://www.sec.gov/Archives/edgar/data/1234567/000123456726000045/"
}

A daily run returns one such record per delisting or deregistration filed in the window — the exact list your security-master scrub needs.

How this compares to Bloomberg

A Bloomberg seat does far more than flag delistings, and if you need the full terminal it earns its keep. But if your actual job is scrubbing dead tickers out of an index, basket, or risk model, you need the delisting filings as a feed your pipeline can ingest — not as a flag buried in a terminal — and this actor delivers exactly that, priced per filing.

FAQ

Q: Which forms does it track? A: By default the delisting and deregistration set — Form 25-NSE, Form 25, and Form 15-12B. Override forms to narrow or extend the set.

Q: What is the difference between Form 25 and Form 15? A: A Form 25 is the exchange's notification of delisting a security; a Form 15-12B is the company's certification that it is deregistering and terminating its SEC reporting obligations. They often appear in sequence as a company leaves the public markets.

Q: Why do I need to provide a User-Agent contact? A: The SEC requires every automated request to EDGAR to identify itself with contact information. Pass your company and email in userAgentContact so requests comply with SEC fair-access policy.

Q: Can I backfill historical delistings? A: Yes — set startDate and endDate to any range to pull historical filings, or use daysBack for a rolling window.

Q: How current is the data? A: Each run reads live EDGAR, so results reflect filings available at run time. Schedule daily for a continuous scrub.

Schema stability & versioning

This actor follows NexGenData's additive-only schema contract. New fields may be added as new JSON keys (defaulting to null for older records), but existing fields are never renamed or removed without a major-version bump and advance notice. Date formats and form-type values are never silently changed. Build your security-master ETL on the five documented fields with confidence.

Compliance & legal

• The actor reads public, unauthenticated SEC EDGAR filings — government disclosure data published for exactly this kind of access.
• Every request identifies itself via the userAgentContact you supply, per SEC fair-access policy.
• No credentials are stored and no paywalled source is involved.
• Treat the feed as informational; verify against the linked primary filing before acting on a delisting in a production index or compliance decision.
