AMPHENOL CORPORATION ANNOUNCES PRICING OF EURO-DENOMINATED SENIOR NOTES OFFERING

Amphenol Corporation (NYSE:APH) (the "Company") announced today the pricing of its offering of €600 million aggregate principal amount of senior notes due 2032 (the "Euro Notes"). The Euro Notes will have an interest rate of 3.125% per annum. The closing of the offering of Euro Notes (the "Euro Notes Offering") is expected to occur on June 16, 2025, subject to the satisfaction of customary closing conditions.

On June 9, 2025, the Company announced the pricing of its offering of $750 million aggregate principal amount of 4.375% senior notes due 2028 (the "USD Notes") by means of a separate prospectus supplement. The closing of the offering of the USD Notes (the "USD Notes Offering") is expected to occur on June 12, 2025, subject to the satisfaction of customary closing conditions. Neither the completion of the Euro Notes Offering nor the offering of the USD Notes is contingent on the completion of the other. Therefore, it is possible that the Euro Notes Offering is completed and the USD Notes Offering is not completed.

The Company intends to use the net proceeds from the Euro Notes Offering and the USD Notes Offering to repay borrowings under the Company's U.S. commercial paper program and for general corporate purposes.

BNP PARIBAS, Citigroup Global Markets Limited and Commerzbank Aktiengesellschaft are serving as the joint book-running managers for the Euro Notes Offering.

The Euro Notes are being offered pursuant to the Company's effective shelf registration statement on file with the Securities and Exchange Commission (the "SEC"). A prospectus supplement describing the terms of this offering will be filed with the SEC. Copies of the prospectus supplement and accompanying prospectus for the offering may be obtained from BNP PARIBAS toll-free at 1-800-854-5674, Citigroup Global Markets Limited toll-free at 1-800-831-9146 and Commerzbank Aktiengesellschaft toll-free at 1-800-233-9164.

This press release does not constitute an offer to sell or the solicitation of an offer to buy the Euro Notes, nor will there be any sale of the Euro Notes, in any jurisdiction in which such offer, solicitation or sale would be unlawful. Any offer, solicitation or sale of the Euro Notes will be made only by means of the prospectus supplement and the accompanying prospectus.

For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the "Insurance Distribution Directive"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the "Prospectus Regulation"). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the Euro Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Euro Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the "EUWA"); (ii) a customer within the meaning of the provisions of FSMA and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA (the "UK Prospectus Regulation").

UK MIFIR product governance / Professional Investors and ECPs Only Target Market

Solely for the purposes of each manufacturer's product approval process, the target market assessment in respect of the Euro Notes has led to the conclusion that: (i) the target market for the Euro Notes is only eligible counterparties as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 ("UK MiFIR"); and (ii) all channels for distribution of the Euro Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Euro Notes (a "distributor") should take into consideration the manufacturers' target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Rules") is responsible for undertaking its own target market assessment in respect of the Euro Notes (by either adopting or refining the manufacturers' target market assessment) and determining appropriate distribution channels.
