Blackstone and TPG are marketing Hologic’s surgical division for more than $4 billion. The private equity firms are working with advisers to sell the unit, which specializes in gynecological surgical equipment.

The sale aims to return cash to investors and reduce debt. This follows the firms' $18.3 billion leveraged buyout of Hologic. The acquisition closed in April 2026 as one of the largest deals of the year.

The process is in early stages and may not result in a deal. Strategic buyers and private equity firms are expected to show interest as investors pressure firms to return capital.
