Thermo Fisher Scientific Inc. (NYSE:TMO) has put part of its diagnostics unit up for sale for around $4 billion in the latest move by a life sciences company to attempt to offload some of its low-growth assets. The company has approached private equity firms through advisers in recent weeks to test interest in a chunk of its diagnostics business, which includes its microbiology unit that makes infectious disease testing equipment, according to three people familiar with the matter. The diagnostics units up for sale generate about $300 million in adjusted earnings and $1.4 billion in sales a year, constituting roughly a third of Thermo Fisher?s wider speciality diagnostics division.

Thermo Fisher is looking to sell the units for more than $4 billion, two people added. The sale process comes amid a volatile period for Thermo Fisher and the wider healthcare sector. Shares in Thermo Fisher have fallen 20% this year, giving it a market value of $157 billion at the close of trading on June 12, 2025, as investors fret over the impact of President Donald Trump?s cuts to the National Institutes of Health on its sales.

Thermo Fisher declined to comment. There are no guarantees that the auction process will lead to a deal and Thermo Fisher may decide to hold on to the asset, the people cautioned.
