Thermo Fisher Scientific Issues $3.8 Billion in Senior Notes for Clario Acquisition

On February 12, 2026, Thermo Fisher Scientific Inc. completed a public offering of senior notes totaling $3.8 billion in aggregate principal amount. The offering consisted of four tranches: $1 billion of 4.215% notes due 2031, $750 million of 4.550% notes due 2033, $1.3 billion of 4.902% notes due 2036, and $750 million of 5.546% notes due 2046. The notes are general unsecured obligations of the company and rank equally with existing unsecured and unsubordinated indebtedness. The company expects net proceeds from the offering to be approximately $3.76 billion after accounting for underwriting discounts and estimated expenses. Thermo Fisher intends to use these proceeds primarily to fund a portion of the cash consideration for its previously announced acquisition of Clario Holdings, Inc. Pending the completion of the acquisition, which remains subject to customary closing conditions and regulatory approvals, the company may use the funds for general corporate purposes, including debt repayment, working capital, capital expenditures, or share repurchases. The indenture governing the notes includes standard covenants that restrict the company and its subsidiaries from incurring debt secured by liens on principal properties or engaging in certain sale and lease-back transactions. Additionally, the company is subject to change-of-control provisions that may require a repurchase offer at 101% of the principal amount if the notes are downgraded below investment grade by at least two of the three major rating agencies following a change of control.

Material changes
  • ›Issued $3.8 billion in senior notes across four tranches maturing between 2031 and 2046.
  • ›Net proceeds of approximately $3.76 billion earmarked for the acquisition of Clario Holdings, Inc.
  • ›Notes include change-of-control provisions requiring repurchase at 101% if accompanied by an investment-grade downgrade.
