Avantor Refinances Euro-Denominated Term Loans at Lower Interest Rate Through Credit Agreement Amendment

Loan Refinancing Lowers Avantor's Euro-Denominated Debt Costs

Avantor disclosed that Avantor Funding, Inc., a wholly owned subsidiary of the parent company, entered into Amendment No. 15 to its Credit Agreement on July 14, 2026. The announcement indicates the Borrower obtained a €374,208,296.62 tranche of senior secured Euro-denominated term loans designated as Incremental B-7 Euro Term Loans. These new loans refinanced and replaced certain existing senior secured euro term loans that had been scheduled to mature on October 9, 2032, and bore a higher interest rate under the prior structure.

The refinancing reduces the interest rate spread on this portion of the company's euro debt portfolio. The newly issued Incremental B-7 Euro Term Loans bear interest at the floating EURIBO Rate plus a spread of 2.00% per annum, compared to the 2.50% spread that applied to the prior euro term loans being replaced. This 50-basis-point reduction in the interest rate spread represents a material cost savings on the €374.2 million outstanding balance, though the filing does not quantify the total annual interest expense reduction in absolute dollar terms.

Maturity Schedule and Collateral Arrangement Remain Unchanged

The disclosure states that the final stated maturity of the Incremental B-7 Euro Term Loans is October 9, 2032, preserving the original maturity date of the debt being refinanced. This alignment ensures the company does not extend its euro-denominated debt obligations beyond the existing debt management timeline. The refinancing therefore represents a like-for-like replacement of maturing obligations rather than a fundamental restructuring of the company's medium-term capital structure.

The filing indicates that the Incremental B-7 Euro Term Loans are guaranteed by the same subsidiaries of Avantor that guarantee the existing credit facilities under the Credit Agreement. Additionally, the new loans and their guarantees are secured by the same collateral of the Borrower and the Guarantors that secures the Borrower's obligations under the Credit Agreement on a pari passu basis. This means the new euro term loans rank equally in security priority with existing secured debt, maintaining consistent creditor protections across the company's secured debt portfolio.

Prepayment Premium Conditions and Early Refinancing Restrictions

The Credit Agreement Amendment includes specific terms governing early prepayment or refinancing of the new Incremental B-7 Euro Term Loans. The filing discloses that if the Borrower prepays, replaces, or refinances all or a portion of these loans at any time prior to the six month anniversary of July 14, 2026, with indebtedness under similar term B loans that are broadly marketed or syndicated to banks and other institutional investors, and such new indebtedness is incurred primarily for repayment or refinancing purposes at an effective yield lower than the Incremental B-7 Euro Term Loans, a prepayment premium would be imposed on the Borrower.

The prepayment premium equals 1.00% of the principal amount of Incremental B-7 Euro Term Loans being prepaid or 1.00% of the principal amount of Incremental B-7 Euro Term Loans outstanding immediately prior to an amendment. The filing specifies that this prepayment premium does not apply to indebtedness incurred in connection with a change of control or certain transformative acquisitions, providing the company with flexibility in those circumstances. The restriction is time-limited to a six-month window from the Effective Date, after which the company would be free to refinance at lower rates without incurring this penalty.

Goldman Sachs Serves as Administrative Agent and Provides Banking Services

The disclosure identifies Goldman Sachs Bank USA as the administrative agent and collateral agent under the Credit Agreement. Goldman Sachs also serves in multiple roles including swing line lender, letter of credit issuer, and Additional Incremental B-7 Euro Term Lender as defined in the Credit Agreement Amendment. This multi-faceted role reflects the bank's central position in managing and participating in Avantor's credit facility.

The filing notes that the Administrative Agent and its affiliates have provided the Borrower and its affiliates with financial advisory, commercial banking, and investment banking services, for which they received customary fees and expenses. The disclosure does not specify the amounts of such fees or detail the nature of the advisory and banking services provided, only that customary compensation was received for these activities.

Amendment No. 15 Represents Ongoing Credit Facility Evolution

The Credit Agreement Amendment is identified as Amendment No. 15 to a Credit Agreement originally dated November 21, 2017. The filing indicates the original Credit Agreement has been amended, restated, extended, supplemented, or otherwise modified in writing numerous times over the nine-year period since inception. The current amendment in July 2026 represents one of a series of adjustments to the company's debt structure since the facility's establishment.

The repeated amendments suggest Avantor has actively managed its credit facility to optimize terms, add new lending tranches, or adjust existing obligations in response to changing business or market conditions. The disclosure does not provide a comprehensive history of all prior amendments or explain the strategic rationale behind each modification, focusing instead on the specific terms of Amendment No. 15 and its immediate impact on the euro-denominated debt outstanding.

Euro Currency Exposure and Interest Rate Risk Considerations

Avantor's refinancing activity in euro-denominated debt indicates the company operates with significant euro-based operations, likely in Europe, requiring euro-denominated funding. The €374.2 million tranche represents a material component of the company's total debt obligations. By refinancing at a lower spread, Avantor reduces its exposure to floating rate interest costs on this portion of debt, though the company remains exposed to fluctuations in the underlying EURIBO Rate benchmark.

The interest rate reduction from EURIBO plus 2.50% to EURIBO plus 2.00% provides the company with immediate cost savings on this tranche, assuming EURIBO rates remain stable. The filing does not disclose the company's total euro-denominated debt outstanding, the proportion of total debt represented by this refinanced tranche, or management's expectations regarding future EURIBO rate movements. Investors may monitor the company's future quarterly disclosures for details on the company's foreign exchange exposure and interest rate hedging strategies.

Filing and Legal Documentation

The disclosure was filed as a Current Report on Form 8-K with the Securities and Exchange Commission on July 17, 2026, three days after the Effective Date of July 14, 2026. The filing includes a summary of material terms of the Credit Agreement Amendment, with the company noting that the summary does not purport to be complete and is qualified in its entirety by reference to the full amendment agreement. The complete Credit Agreement Amendment is attached as Exhibit 10.1 to the Current Report and is incorporated herein by reference.

The filing was signed by Claudius Sokenu, who holds the title of Executive Vice President, Chief Legal and Compliance Officer and Secretary, identified as a duly authorized officer of Avantor, Inc. The company is incorporated in Delaware and maintains principal executive offices at Radnor Corporate Center, Building One, Suite 200, 100 Matsonford Road, Radnor, Pennsylvania 19087. Avantor is registered on the New York Stock Exchange under the ticker symbol AVTR.

Investor Considerations and Debt Management Implications

The refinancing demonstrates Avantor's ability to access capital markets and refinance maturing obligations at improved terms, reducing the company's interest expense burden on euro-denominated debt. The 50-basis-point reduction in borrowing cost on €374.2 million of debt should provide modest but measurable improvements to the company's future interest expense and cash flow. The preservation of the October 9, 2032 maturity date ensures the company continues to manage its debt maturities on a consistent schedule.

Investors may view the successful refinancing as a positive indicator of Avantor's creditworthiness and continued access to credit markets at competitive terms. The immediate share price impact was not clear from available public information. The filing does not provide guidance on the company's total debt position, leverage ratios, or future refinancing activities, leaving those details for future quarterly earnings reports and other periodic disclosures to the SEC.
