What Are Corporate Actions? Types, Dates, and What Investors Need to Know

A corporate action is any decision by a public company that directly affects its shares or shareholders. Common examples include dividends, stock splits, mergers, and delistings. Some happen automatically. Others require shareholders to respond by a deadline.

A dividend moves value out of the company and into shareholders' accounts, typically as cash. A stock split changes the number of shares in circulation without moving any value anywhere. After a dividend, the company has less cash. After a stock split, nothing about the company's fundamentals changes.

It depends on the deal structure. In a cash merger, your shares are bought at the offer price and you receive cash. In a stock-for-stock merger, your shares are exchanged for shares of the acquiring company at a set ratio. If the deal offers a choice between cash and stock, you will need to respond by a stated deadline or a default outcome applies.

Dividend capture involves buying shares before the ex-dividend date to collect the upcoming dividend, then selling shortly after. In theory the share price falls by approximately the dividend amount on the ex-date, which offsets the gain. In practice, outcomes vary depending on market conditions, taxes, and transaction costs. It is a known strategy but not a reliable source of risk-free returns.
