03:09 PM EDT, 09/30/2025 (MT Newswires) -- Thermo Fisher Scientific ( TMO ) is offering $2.5 billion of high-grade bonds in four parts, Bloomberg reported Tuesday.

The longest part of the offering is a 12-year security that will yield 0.75 percentage point above Treasuries, after initial talks of around a 1 percentage point spread, a source with knowledge of the matter told Bloomberg.

The proceeds of the offering will be used for general corporate purposes, which may include the acquisitions, repayment and refinancing of debt, working capital and capital expenditures, or share repurchases, Thermo Fisher said in a preliminary prospectus supplement filed Tuesday.

Thermo Fisher did not immediately reply to a request for comment from MT Newswires.
