Other Events

On October 30, 2025, Hubbell Incorporated (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with BofA Securities, Inc., HSBC Securities (USA) Inc. and J.P. Morgan Securities LLC, as representatives of the several underwriters named in Schedule I thereto (collectively, the “Underwriters”), relating to the Company’s public offering of $400,000,000 aggregate principal amount of its 4.800% Senior Notes due 2035 (the “Notes”). The Company expects to use the net proceeds from the offering of the Notes, together with cash on hand, to redeem in full all of the Company’s outstanding 3.350% Senior Notes due 2026 in an aggregate principal amount of $400,000,000, which have a stated maturity date of March 1, 2026, and to pay any premium and accrued interest in respect thereof.

The offering of the Notes was made pursuant to the Company’s shelf registration statement on Form S-3 (Registration No. 333-289041), filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 29, 2025. The Company expects the offering of the Notes to close on November 14, 2025, subject to customary closing conditions.

Pursuant to the Underwriting Agreement, the Company agreed to sell the Notes to the Underwriters and the Underwriters agreed to purchase the Notes for resale to the public. The Underwriting Agreement includes customary representations, warranties and covenants by the Company. The Underwriting Agreement also provides for customary indemnification by each of the Company and the Underwriters against certain liabilities and customary contribution provisions in respect of those liabilities.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Also on October 30, 2025, the Company issued a press release announcing the pricing of the Notes, which press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
