The acquisition process can take anywhere from a few weeks to several months, depending on the complexity of the deal and the number of parties involved. In most cases, the process begins with an informal offer from one company to another. This is followed by a period of due diligence, during which both parties conduct extensive research on each other. Once the due diligence is complete, the two companies negotiate a final purchase price and contract. The acquisition is then completed, and the two companies begin the process of integrating their operations.
