What Happens When A Company Is Acquired

When a listed company agrees to be acquired, its shareholders eventually stop holding that company and hold something else. The path between announcement and completion has several defined stages.

The announcement and the offer terms

An agreement specifies what each share will receive: a cash amount, a ratio of the acquirer's shares, or a combination of both.

Cash offers fix the value per share subject to completion. Share offers leave the value moving with the acquirer's price until the exchange occurs.

The target's share price typically moves toward the offer value immediately, and the remaining gap reflects the market's assessment of completion risk and timing.

Why the gap persists until closing

Deals require shareholder approval, regulatory clearance and satisfaction of conditions written into the agreement, any of which can fail or take longer than expected.

Antitrust review in particular can extend for many months and can result in required divestitures or a challenge that ends the transaction.

The discount to the offer price therefore compensates for the possibility that the shares revert to their standalone value.

What shareholders are asked to do

Holders receive proxy materials describing the transaction, the board's reasoning and the terms, and are asked to vote.

In a tender offer structure, holders are instead asked to tender their shares, and the offer proceeds if enough are tendered.

Most individual holders take no action beyond voting, and their shares are converted automatically at closing through their broker. Dissenting holders in some structures have appraisal rights, a statutory process whose availability and procedure vary by the state of incorporation.

The mechanics at completion

On the closing date the target's shares stop trading and are removed from the exchange and from any indexes that included them.

Cash or acquirer shares appear in the account within a short period afterward, with fractional entitlements typically settled in cash.

Index funds holding the target must adjust, which is why index changes often cluster around completion dates rather than announcements.

What the documents contain

The merger agreement and proxy statement are filed publicly and describe the conditions, termination provisions and any fees payable if the deal fails.

They also disclose the background of the negotiation and any conflicts involving management, which is often the most informative section. It sets out who approached whom, which other parties were contacted, and what the board's advisers concluded about the terms.

Because the treatment of proceeds depends on the structure and on individual circumstances, that aspect is a question for a qualified tax professional.
