WEC Energy Group, Inc. entered into an underwriting agreement to issue and sell $600,000,000 aggregate principal amount of 5.625% Fixed‑to‑Fixed Reset Rate Junior Subordinated Notes due 2056. The notes are being offered in a registered transaction under a Form S‑3 shelf (Registration No. 333-281253).

Barclays Capital, BofA Securities, Citigroup, Morgan Stanley, U.S. Bancorp Investments, and Wells Fargo Securities are acting as representatives of the underwriters. The filing also includes the securities resolution under the company’s existing indenture and related legal opinions and consents. This transaction adds long-dated junior subordinated debt to the company’s capital structure, using a registered public offering format.

WEC Energy Group launched a preliminary prospectus supplement for a primary offering of Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056. The notes pay a fixed rate until 2031, then reset every five years to the Five-Year Treasury Rate plus a spread, with a floor equal to the initial rate. Interest is paid semi-annually.

The company may defer interest for up to 20 consecutive semi-annual periods (up to 10 years); deferred amounts accrue and compound. During deferral, certain dividends, par‑or‑junior debt payments, and similar actions are restricted. The notes are unsecured and junior to Senior Indebtedness; Senior Indebtedness was approximately $6.3 billion as of September 30, 2025. The notes are not expected to be listed.

WEC intends to use net proceeds to repay short‑term debt and for general corporate purposes. Short‑term debt outstanding was $905.0 million at a weighted average 4.26% as of September 30, 2025. The notes may be redeemed at specified times at 100%, and at 102% upon certain rating agency methodology changes, or at 100% upon certain tax events.

WEC Energy Group entered an equity distribution agreement allowing it to offer and sell, from time to time, up to $3.0 billion of its common stock through designated sales agents or to them as principals. The program also permits forward sale agreements, including initially priced forwards and collared forwards, entered with affiliated forward purchasers under its effective Form S-3 shelf.

For forward transactions, WEC will not initially receive proceeds from sales of borrowed shares; it expects cash only upon future physical settlement at the applicable forward sale price, adjusted for commissions, interest factors and expected dividends. Collared forwards establish a floor and cap determined after an initial hedging period, with settlement payments reflecting those terms. Sales agents and forward sellers may receive commissions of up to 1.00% of sale prices. Actual sales will occur at WEC’s discretion based on market conditions, trading price, capital needs and funding determinations.
