On March 30, 2023, Amphenol Corporation (the “Company”) issued and sold $350,000,000 aggregate principal amount of its 4.750% Senior Notes due 2026 (the “Notes”) pursuant to the Company’s Registration Statement on Form S-3 (No. 333-270605), including the related prospectus dated March 16, 2023, as supplemented by the prospectus supplement dated March 27, 2023. The Notes were sold in an underwritten public offering pursuant to an underwriting agreement, dated March 27, 2023, by and between the Company and BNP Paribas Securities Corp., BofA Securities, Inc. and J.P. Morgan Securities LLC, as representatives of the several Underwriters named in Schedule A thereto.

The Company received net proceeds of approximately $346.4 million from the offering, after deducting the underwriting discounts and estimated offering expenses payable by us. The Company intends to use the net proceeds from the offering of the Notes to repay borrowings under the Company’s U.S. commercial paper program and for general corporate purposes.

The Notes were issued pursuant to an indenture dated as of March 16, 2023 (the “Indenture”) between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), and certain of the terms of the Notes were established pursuant to an Officers’ Certificate dated March 30, 2023 (the “Officers’ Certificate”) in accordance with the Indenture. The Indenture and Officers’ Certificate contain certain covenants and events of default and other customary provisions.

The Notes bear interest at a rate of 4.750% per year. Interest on the Notes is payable semi-annually on March 30 and September 30 of each year, beginning on September 30, 2023. The Company will make each interest payment to the holders of record on the immediately preceding March 15 and September 15. The Notes will mature on March 30, 2026. The Company may redeem, from time to time at its option, some or all of the Notes at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, plus a “make-whole” premium. The Notes are unsecured, unsubordinated and rank equally in right of payment with all of the Company’s other unsecured unsubordinated senior indebtedness and senior obligations.

The above descriptions of the Indenture, the Officers’ Certificate and the Notes are qualified in their entirety by reference to the Indenture, the Officers’ Certificate, and the Notes, which are filed as Exhibits 4.1, 4.2 and 4.3, respectively, to this Current Report on Form 8-K, and are incorporated by reference herein.

The exhibits to this Current Report on Form 8-K (except for Exhibit 104) are hereby incorporated by reference in the Registration Statement (No. 333-270605).
