Astorg Partners is nearing a deal to buy contract drug development and manufacturing company CordenPharma for more than 2.5 billion euros ($2.6 billion), according to people familiar with the matter.

Advent International and Apax Partners were among other firms exploring a takeover of the company, Bloomberg News reported previously. Astorg declined to comment while Corden wasn’t immediately available for comment.
