Exchange Ratio

The relative number of shares an acquiring company offers for each share of the target company in an M&A transaction.

An exchange ratio represents the relative number of shares an acquiring company offers to issue to the shareholders of a target company for each share they currently own in an M&A transaction. This metric is the cornerstone of stock-for-stock mergers, establishing how ownership of the combined entity will be distributed once the deal closes. The ratio can be structured as either fixed or floating. A fixed exchange ratio remains constant regardless of stock price movements, meaning the target's shareholders receive a predictable piece of the new company, but the dollar value of the deal will fluctuate alongside the acquirer's stock price. Conversely, a floating exchange ratio adjusts dynamically to deliver a guaranteed, specific dollar value of shares to the target's shareholders at closing, meaning the actual number of shares issued will change based on market prices. Investors analyze the exchange ratio to calculate the implied value of the acquisition offer and to assess deal-completion risk. If the acquiring company's stock price drops significantly after the deal is announced, the implied value of a fixed-ratio deal drops with it, which typically drags down the target company's stock price. Retail investors must also watch for collar structures, which are contractual limits that protect either the buyer or seller if stock prices move beyond specified boundaries.

Company A agrees to acquire Company B in an all-stock deal with a fixed exchange ratio of 1.5. If Company A's stock is currently trading at $60 per share, the implied value of the offer for Company B's shareholders is $90 per share ($60 1.5).
