Merck has agreed to acquire Cidara Therapeutics in a $9.2 billion deal, aiming to bolster its portfolio of flu prevention treatments.

Cidara's lead product, CD101, is a novel antiviral agent designed to prevent influenza, which could significantly benefit Merck's respiratory franchise. The deal, valued at $37 per share, represents a 105% premium to Cidara's closing price on February 24, 2023.
