01—Abstract

Summary

Summary of the 8-K filed August 13, 2026. Cited figures are marked; the original filing is the authoritative source.

Duke Energy Corporation (DUK) filed this 8-K on August 13, 2026 to report the closing of a public offering of equity units.

The company issued 40,000,000 Corporate Units at a stated amount of $50a each, for gross proceeds of $2.0 billion, including the full exercise of the underwriters' 5,000,000-unit over-allotment option. Estimated net proceeds to the company are approximately $1,965 million after underwriting discounts, before other offering expenses. Each unit combines a stock purchase contract obligating the holder to buy DUK common stock on August 1, 2029, with a 1/40 interest in each of two $1,000 principal series of 4.85% Remarketable Senior Notes due 2032 and 2036.

This is a mandatory equity-linked financing, so it will add shares to the company's share count once the contracts settle. The key economic terms are a 7.75%b total annual distribution on the units, made up of a 2.90% contract adjustment payment and 4.85% interest on the RSNs. Settlement is mandatory on August 1, 2029, at a rate between 0.3301 and 0.4126 shares per contract, depending on the stock price.

The reference price is about $121.18c, so the maximum settlement rate applies at or below that level, and the minimum applies above roughly $151.47 (a 25% premium). The RSNs will be remarketed before settlement, which can reset their coupon. Deferred contract adjustment payments accrue at 7.75%, and a fundamental change early settlement feature provides make-whole shares.

The offering is consistent with a balance sheet strategy that pairs equity with the company's capital-intensive utility capex program. Investors should weigh the dilution from future share issuance against the financing's benefit to credit metrics. The filing is largely administrative.

It documents the indenture supplements, the purchase contract and pledge agreement, the underwriting agreement, and legal opinions incorporated into the company's Form S-3 shelf registration (No. 333-290475). It does not disclose any change in earnings guidance, operations, or material litigation. Investors should read the full prospectus supplement for risk factors and details on remarketing and early settlement.
