(Updates with Sixth Street's response in the fifth paragraph)

Brighthouse Financial's (BHF) potential acquisition by Sixth Street has been revived as another merger deal is delayed by regulatory review, Bloomberg reported late Tuesday, citing unnamed people familiar with the matter.

Sixth Street's Talcott Financial sent a letter to Brighthouse's board restating its ambition to acquire the insurance company if the acquisition by Aquarian fails, the report said.

The Aquarian deal's financing is under scrutiny by the Delaware Department of Insurance, the report said.

Brighthouse can abandon the deal if regulators don't approve it by Dec. 6, the report said.

Sixth Street declined to comment. Brighthouse and Aquarian did not reply to MT Newswires' requests for comment.
