# Corporate Events

> Registry-level corporate actions for a company: stock splits, mergers and ticker changes.

Corporate Events returns registry-level corporate actions for one company: stock splits, mergers and ticker changes. Each observation is one action with its effective date. These are the structural events that change what a company's identifiers and price series mean.

## What You Can Use Corporate Events For

Adjust a price or share-count series correctly across a split. Explain a discontinuity in a ticker-keyed dataset. Trace a company through a merger or a re-listing. Decide whether an apparent 50% price drop was a market move or a two-for-one split.

## Why Corporate Events Matter for Price Series

A stock split changes the price and the share count without changing the company's value. A series that is not split-adjusted therefore shows a large apparent move on the split date, which reads exactly like a market event.

Market capitalisation is unaffected by a split, which is why it is the reliable check: if the price halved but the market cap did not, the cause was a split, not a sell-off.

## Corporate Events Date Convention

Each action carries the date it took effect. A ticker change takes effect on the date the new symbol began trading, which is also the boundary between two rows in [Company Listings](/companies/listings).

## Corporate Events Sources

Corporate actions come from exchange and regulator notices. They are structural registry facts, not extracted from news.

This layer is sparsely populated today (`history_status: "partial"` in the coverage block). An empty `data` array means no action is **recorded** for the company — it is not evidence that none ever happened. For ETF share splits, which are fully adjudicated, see [ETF Splits](/etf/splits).

## Query Corporate Events

Use the company events endpoint with a canonical `company_id`.

<ParamField path="company_id" type="string" required>
  Canonical company id, for example `cmp_008395`.
</ParamField>

<Note>
  This endpoint is not the live news event feed. For what is happening to a company right now — filings, wires and IR disclosures aggregated into labelled events — see [Company News Events](/news/news-events).
