In a reverse takeover, shareholders of the private company purchase control of the public shell company and then merge it with the private company. The publicly traded corporation is called a "shell" since all that exists of the original company is its organizational structure. The private company shareholders receive a substantial majority of the shares of the public company and control of its board of directors. The transaction can be accomplished within weeks. If the shell is an SEC-registered company, the private company does not go through an expensive and time-consuming review with state and federal regulators because this process was completed beforehand with the public company. However, a comprehensive disclosure document containing audited financial statements and significant legal disclosures is required by the Securities and Exchange Commission for reporting issuers. The disclosure is filed on Form 8-K and is filed immediately upon completion of the reverse merger transaction.

The transaction involves the private and shell company exchanging information on each other, negotiating the merger terms, and signing a share exchange agreement. At the closing, the shell company issues a substantial majority of its shares and board control to the shareholders of the private company. The private company's shareholders pay for the shell company by contributing their shares in the private company to the shell company that they now control. This share exchange and change of control completes the reverse takeover, transforming the formerly privately held company into a publicly held company.
