An S-4 is a form filed with the SEC relating to a merger or an acquisition or in an exchange offering (trading stocks for stocks or bonds for bonds, usually after a merger).

These forms are often filed with the SEC before the merger/acquisition is publicly announced and therefore investors carefully watch the SEC filings in an attempt to invest in a company before its stock price adjusts.
