shark(redirected from Shark (cipher))
Also found in: Dictionary, Thesaurus, Medical, Encyclopedia.
A company that is offering or executing a hostile takeover. If a firm makes an offer to shareholders to acquire a publicly-traded company after the board of directors refused, or if it bypasses the board completely, one refers to the acquiring firm as a shark. This is a derogatory term, and so one might expect the board, management, or even employees, to use it more than shareholders. See also: Shark repellent.
An investor or firm that is hostile to the target firm's management and that is interested in taking over the firm.
