Rhea-AI Filing Summary

Thermo Fisher Scientific Inc., through its finance subsidiary Thermo Fisher Scientific (Finance I) B.V., issued €1,000,000,000 of Floating Rate Senior Notes due 2027 and €1,100,000,000 of 3.628% Senior Notes due 2035 in a public offering, fully and unconditionally guaranteed on a senior unsecured basis by the company. The notes were issued under an existing indenture and a new supplemental indenture, with quarterly interest on the floating rate notes and annual interest on the fixed rate notes.

The 2035 fixed rate notes are redeemable before a September 1, 2035 par call date at a make-whole redemption price and at par thereafter, and both series include a change-of-control put at 101% of principal plus accrued interest if the company undergoes a qualifying change of control with concurrent ratings downgrades. The company expects net proceeds of approximately €2.09 billion and intends to use them for general corporate purposes, including potential acquisitions, debt repayment or refinancing, working capital, capital spending, and share repurchases, or for temporary investment in short-term liquid instruments.

Insights

Thermo Fisher adds €2.09B of senior euro notes, extending its debt profile.

Thermo Fisher Scientific has raised €1,000,000,000 of floating rate senior notes due 2027 and €1,100,000,000 of 3.628% senior notes due 2035 through its Dutch finance subsidiary, fully guaranteed on a senior unsecured basis by the parent. The notes rank pari passu with existing unsecured, unsubordinated debt and are structurally subordinated to liabilities at other subsidiaries.

The fixed 2035 notes feature a make-whole call before the September 1, 2035 par call date and are redeemable at par thereafter, giving the issuer flexibility to refinance if conditions are favorable. Both tranches carry a change-of-control provision requiring an offer to repurchase at 101% of principal plus accrued interest if a defined change of control coincides with downgrades below investment grade by at least two major rating agencies.

Net proceeds are expected to be approximately €2.09 billion, earmarked for general corporate purposes such as acquisitions, debt repayment or refinancing, working capital, capital expenditures, or equity repurchases, with temporary investment in short-term liquid instruments until deployment. The overall impact on investors depends on how the company ultimately allocates this funding and on future interest rate and credit conditions.

Item 1.01
Entry into a Material Definitive Agreement.

On December 1, 2025, Thermo Fisher Scientific (Finance I) B.V. (“Thermo Fisher International”), an indirect, wholly-owned finance subsidiary of Thermo Fisher Scientific Inc. (the “Company”), issued €1,000,000,000 aggregate principal amount of Floating Rate Senior Notes due 2027 (the “Floating Rate Notes”) and €1,100,000,000 aggregate principal amount of 3.628% Senior Notes due 2035 (the “Fixed Rate Notes” and, together with the Floating Rate Notes, the “Notes”) in a public offering (the “Offering”) pursuant to a registration statement on Form S-3ASR (File No. 333-285159) and a preliminary prospectus supplement and prospectus supplement related to the offering of the Notes, each as previously filed with the Securities and Exchange Commission.  The Company has fully and unconditionally guaranteed the Notes on a senior unsecured basis (the “Guarantees” and, together with the Notes, the “Securities”).

The Securities were issued under an indenture, dated as of August 9, 2016 (the “Base Indenture”), and the Fifth Supplemental Indenture, dated as of December 1, 2025 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among Thermo Fisher International, as issuer, the Company, as guarantor, and The Bank of New York Mellon Trust Company, N.A., as trustee.

The Floating Rate Notes will mature on December 1, 2027 and the Fixed Rate Notes will mature on December 1, 2035. Interest on the Floating Rate Notes will be paid quarterly in arrears on March 1, June 1, September 1 and December 1 of each year, beginning on March 1, 2026. Interest on the Fixed Rate Notes will be paid annually in arrears on December 1 of each year, beginning on December 1, 2026.

Prior to September 1, 2035 (the “Par Call Date”), Thermo Fisher International may redeem the Fixed Rate Notes, in whole at any time or in part from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Fixed Rate Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest in respect of the Fixed Rate Notes being redeemed (not including any portion of the payments of interest accrued but unpaid as of the date of redemption and assuming that such Fixed Rate Notes to be redeemed matured on the Par Call Date), discounted to the date of redemption on an annual basis (ACTUAL/ACTUAL (ICMA)), using a discount rate equal to the Comparable Bond Rate (as defined in the Indenture) plus 15 basis points, plus accrued and unpaid interest on the Fixed Rate Notes being redeemed, if any, to, but excluding, the date of redemption.

In addition, on and after the Par Call Date, the Company may redeem some or all of the Fixed Rate Notes at a redemption price equal to 100% of the principal amount of the Fixed Rate Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption.

Upon the occurrence of a change of control (as defined in the Indenture) of the Company and a contemporaneous downgrade of the Notes below an investment grade rating by at least two of Moody’s Investors Service, Inc., S&P Global Ratings, a division of S&P Global, Inc., and Fitch Ratings Limited, Thermo Fisher International will, in certain circumstances, be required to make an offer to purchase the Notes at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.

The Notes are general unsecured obligations of Thermo Fisher International.  The Notes rank equally in right of payment with existing and any future unsecured and unsubordinated indebtedness of Thermo Fisher International and rank senior in right of payment to any existing and future indebtedness of Thermo Fisher International that is subordinated to the Notes.  The Notes are also effectively subordinated in right of payment to all future secured indebtedness of Thermo Fisher International to the extent of the assets securing such indebtedness, and are structurally subordinated to all existing and any future indebtedness and any other liabilities and commitments (including trade payables and lease obligations) of its subsidiaries.


The Guarantees are general unsecured obligations of the Company.  The Guarantees rank equally in right of payment with existing and any future unsecured and unsubordinated indebtedness of the Company and will rank senior in right of payment to any existing and future indebtedness of the Company that is subordinated to the Guarantees.  The Guarantees are also effectively subordinated in right of payment to all existing and future secured indebtedness of the Company to the extent of the assets securing such indebtedness, and are structurally subordinated to all existing and any future indebtedness and any other liabilities and commitments (including trade payables and lease obligations) of its subsidiaries (other than, with respect to Thermo Fisher International, the Notes).

The Indenture contains limited affirmative and negative covenants of the Company and Thermo Fisher International.  The negative covenants restrict the ability of the Company and its subsidiaries to incur debt secured by liens on Principal Properties (as defined in the Indenture) or on shares of capital stock of any of the Company’s direct or indirect subsidiaries that owns a Principal Property and engage in sale and lease-back transactions with respect to any Principal Property.  The Indenture also limits the ability of each of the Company and Thermo Fisher International to merge or consolidate or sell all or substantially all of their respective assets.

Upon the occurrence of an event of default under the Indenture, which includes payment defaults, defaults in the performance of affirmative and negative covenants, bankruptcy and insolvency related defaults and failure to pay certain indebtedness, the obligations of Thermo Fisher International under the Notes may be accelerated, in which case the entire principal amount of the Notes would be immediately due and payable.

Wilmer Cutler Pickering Hale and Dorr LLP, U.S. counsel to the Company and Thermo Fisher International, has issued an opinion to the Company and Thermo Fisher International, dated December 1, 2025, regarding the legality of the Securities, and Linklaters LLP, Dutch counsel to Thermo Fisher International, has issued an opinion to Thermo Fisher International, dated December 1, 2025, regarding the Notes.  Copies of these opinions are filed as Exhibits 5.1 and 5.2 hereto, respectively.

The foregoing description is qualified in its entirety by reference to the full text of the Base Indenture and the Supplemental Indenture, which are filed with this report as Exhibits 4.1 and 4.2 hereto, respectively. Each of the foregoing documents is incorporated herein by reference.

Item 8.01
Other Events.

The sale of the Securities was made pursuant to the terms of an Underwriting Agreement, dated November 24, 2025 (the “Underwriting Agreement”), among Thermo Fisher International, as issuer, the Company, as parent guarantor, and Barclays Bank PLC, BNP PARIBAS, HSBC Continental Europe Morgan Stanley & Co. International plc, as lead managers of the several underwriters named in Schedule A to the Underwriting Agreement.

The Company expects that the net proceeds from the sale of the Notes will be approximately €2.09 billion, after deducting underwriting discounts and estimated offering expenses.  The Company intends to use the net proceeds of the Offering for general corporate purposes, which may include the acquisition of companies or businesses, repayment and refinancing of debt, working capital and capital expenditures or the repurchase of its outstanding equity securities, or the Company may temporarily invest the net proceeds in short-term, liquid investments until they are used for their ultimate purpose.

The foregoing description is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed with this report as Exhibit 1.1 hereto and is incorporated herein by reference.
