Bluefin Merger Subsidiary, Inc. is a special‑purpose entity formed to facilitate a specific merger and acquisition transaction. As a “merger sub,” it typically serves as a wholly owned subsidiary of an acquiring company and has no independent commercial operations. Its sole function is to enter into a merger agreement with a target company and carry out the technical steps required to complete the acquisition.
Merger subsidiaries are commonly used to streamline deals under U.S. corporate and securities law, often through a tender offer followed by a second‑step merger at the same terms. After the transaction closes, the merger subsidiary is usually merged into the target and ceases to exist, with the target continuing as a subsidiary of the acquirer.
