Corporate Actions Calendar — Splits, Spinoffs, M&A, Deals

Track the structural events that move single stocks independently of the market — stock splits and reverse splits, spinoffs, special dividends, mergers, acquisitions, and tender offers — in one typed dataset. Each row carries the action type, split ratio or deal value, cash/stock consideration, status (Announced → Approved → Completed → Cancelled), effective date, and computed days-to-effective, so a special-situations desk can build a position straight from the row. It pairs a curated calendar of the high-conviction names special-situations capital actually trades with live SEC 8-K discovery of brand-new announcements, plus a Yahoo Finance price snapshot — pay-per-result, no six-figure terminal contract.

How it works (honest architecture)

This is not a complete corporate-actions database and does not claim institutional breadth. It combines two layers, and every row tells you which one it came from via data_source:

1. Curated high-conviction calendar — a maintained list of notable splits, spinoffs, special dividends, and deals that special-situations capital actually trades (e.g. large-cap forward splits, marquee spinoffs, announced acquisitions). Values are captured from public 8-Ks and press releases and refreshed per build, so the curated calendar skews toward well-known and historically completed actions.
2. Live SEC 8-K discovery — six EDGAR full-text phrase queries over a trailing 90-day window ("stock split", "reverse stock split", "special dividend", "spin-off", "merger agreement", "tender offer") that surface brand-new announcements as they hit EDGAR.

A Yahoo Finance snapshot adds current_price / market_cap on a best-effort basis (may be null under throttling). "Upcoming" events lean on the live 8-K layer; the curated calendar leans historical.

Use cases

• Deal-arb worklist — pull Merger/Acquisition rows, filter upcoming, track status for breakages.
• Index-rebalance prep — forward splits on large-caps ahead of effective dates.
• Spinoff fund setup — Spinoff action type across all dates (Greenblatt-style).
• Reverse-split / delisting watch — reverse splits in recent_30d as a distress screen.
• Options vol prep — flag splits and cash deals for vol-surface adjustments.

Sample input

{
  "action_types": ["Merger", "Acquisition"],
  "date_range": "upcoming",
  "min_market_cap_billion": 1.0,
  "limit": 100
}

Sample output

{
  "symbol": "PEAR",
  "company_name": "Pear Therapeutics",
  "sector": "Healthcare",
  "action_type": "Acquisition",
  "ratio": null,
  "current_price": null,
  "market_cap_usd": 150000000,
  "effective_date": "2026-04-30",
  "announcement_date": "2026-03-21",
  "target_company": "Pear Therapeutics",
  "acquirer": "Click Therapeutics",
  "deal_value_usd": 180000000,
  "consideration": "$3.20 cash per share",
  "status": "Completed",
  "days_to_effective": -60,
  "data_source": "curated_baseline"
}

data_source is curated_baseline, sec_edgar_8k, or both. current_price may be null when Yahoo Finance throttles.

FAQ

Where does the data come from? A curated calendar of high-profile corporate actions plus live SEC 8-K full-text discovery and Yahoo Finance price snapshots. Each row's data_source shows its provenance.

How do I get only upcoming events? Set date_range="upcoming" to filter on a future effective_date. Upcoming coverage relies mainly on the live 8-K discovery layer.

Are deal values and prices guaranteed accurate? Curated values are accurate at point of capture from public 8-Ks and press releases; live prices are best-effort from Yahoo Finance — reconcile against your broker for execution.

Do you cover non-US issuers? Strongest for US-listed names including US-ADRs; pure foreign listings are out of scope.

Can I filter by sector or market cap? Yes — sector (substring match) and min_market_cap_billion (floor).
