Hologic CEO Steve MacMillan to Retire Following Go-Private Deal with Blackstone and TPG

Steve MacMillan, the Chief Executive Officer of Hologic Inc., has announced his retirement after leading the company for more than 12 years. The leadership transition follows the recent agreement to take the medical technology firm private through an acquisition by Blackstone and TPG. The transaction is slated for completion around April 7, 2026, at which point a successor will be named to lead the company under its new ownership. During his tenure, MacMillan oversaw significant strategic growth and transformation, positioning the company as a leader in its field. This retirement is viewed as a planned component of the company's shift from public markets to private equity control. Market impact is expected to remain neutral as the leadership change is directly tied to the pre-established go-private timeline.
