Welcome to our dedicated page for Duke Energy SEC filings (Ticker: DUKB), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Duke Energy Corporation filings document the issuer behind DUKB, the company’s 5.625% Junior Subordinated Debentures due September 15, 2078. The records identify Duke Energy’s registered securities, including common stock, preferred depositary shares, senior notes and the DUKB junior subordinated debentures, and include material-event disclosures and capital-structure information.
Proxy and current-report filings also describe governance and annual meeting matters for Duke Energy and reference its regulated utility and natural gas subsidiaries, including Duke Energy Carolinas, Duke Energy Progress, Duke Energy Florida, Duke Energy Ohio, Duke Energy Indiana and Piedmont Natural Gas. These disclosures cover shareholder voting matters, board and governance topics, operating-company structure, energy infrastructure investment, generation resources and related risk and regulatory subjects.
Duke Energy Corporation completed an underwritten offering of 40,000,000 equity units, including 5,000,000 units sold under the underwriters’ over-allotment option, each with a stated amount of $50, for an aggregate offering size of $2,000,000,000.
Each equity unit initially consists of a stock purchase contract obligating the holder to buy common stock for $50 in cash no later than August 1, 2029, plus 1/40 interests in the company’s 4.85% Remarketable Senior Notes due 2032 and 2036. Total annual distributions on corporate units are 7.75% of stated amount, combining 2.90% contract adjustment payments and 4.85% RSN interest. Estimated net proceeds are about $1,719 million (or $1,965 million if the over-allotment option is fully exercised). Duke Energy intends to list the corporate units on the NYSE under the symbol “DUKU”.
Duke Energy Corporation is offering 35,000,000 Equity Units, each with a stated amount of $50, initially issued as Corporate Units composed of a stock purchase contract and undivided interests in two series of Remarketable Senior Notes due 2032 and 2036. The company may sell up to an additional 5,000,000 Equity Units to cover over-allotments. The Corporate Units are expected to be listed on the NYSE under the symbol “DUKU”, while the common stock trades under “DUK”.
Each purchase contract obligates holders to buy Duke Energy common stock on August 1, 2029 for $50, with the number of shares determined by a formula based on the 20‑day volume‑weighted average price before settlement, subject to anti‑dilution and fundamental change adjustments. Holders receive quarterly contract adjustment payments and interest on the RSNs; both RSN series are senior unsecured obligations, structurally subordinated to subsidiary liabilities. The RSNs may be remarketed, with proceeds funding Treasury portfolios that secure stock purchase obligations.
Net proceeds are expected to be used to redeem $500 million of 3.25% junior subordinated debentures due 2082, repay a portion of approximately $2.1 billion of commercial paper (weighted average rate 3.91%), and for general corporate purposes. Separately, subsidiary Duke Energy Progress filed a comprehensive North Carolina rate settlement featuring a 9.8% ROE, an approximately $17.8 billion retail rate base and about $3.4 billion of multi‑year capital, which remains subject to regulatory approval and is expected to trigger about $30 million of one‑time pre‑tax charges.
Duke Energy Corporation reported second-quarter 2026 earnings per share (EPS) of $1.38 on a GAAP basis and $1.43 on an adjusted basis, compared with $1.25 reported and adjusted EPS in the second quarter of 2025. The $0.05 difference between reported and adjusted EPS in 2026 reflects $39 million of regulatory settlement charges at the Electric Utilities and Infrastructure segment.
Electric Utilities and Infrastructure delivered second-quarter 2026 segment income of $1,271 million reported and $1,310 million adjusted, up from $1,194 million a year earlier, driven mainly by recovery of infrastructure investments, partially offset by higher depreciation and interest expense. Gas Utilities and Infrastructure segment income was $10 million versus $6 million in 2025, while Other posted a segment loss of $204 million versus a loss of $228 million.
Consolidated operating revenues for the quarter were $7,592 million compared with $7,508 million in 2025. Net income available to common stockholders was $1,077 million versus $971 million. The consolidated reported effective tax rate rose to 12.3% from 10.6%, primarily due to lower amortization of excess deferred taxes. For the first six months of 2026, net cash provided by operating activities was $4,272 million compared with $5,040 million in 2025. Management reaffirmed 2026 adjusted EPS guidance of $6.55–$6.80 and a long-term adjusted EPS growth rate of 5%–7% through 2030 off the 2025 midpoint of $6.30.
Duke Energy Carolinas, LLC filed a Comprehensive Revenue Requirement Settlement with North Carolina stakeholders in its 2025 rate case and Performance Based Regulation application. The agreement provides for a 9.8% return on equity with a 53% equity capital structure and a retail rate base of about $25.7 billion for the historic base case. It also includes roughly $3.8 billion of capital in a multi-year rate plan with an annual refund mechanism and lowers the combined revised revenue requirement increase to $496 million, with net annualized customer rate increases ranging up to 7.4% across the plan.
The settlement framework includes evaluating a delay of Duke Energy Carolinas’ next base rate case filing until no earlier than November 1, 2028, contingent on the North Carolina Utilities Commission granting deferral of costs for certain new generating assets. Intervening parties agreed to pursue good faith settlement discussions in the Duke Energy Progress rate case to seek a substantially similar framework. The stipulations are expected to result in one-time pre-tax accounting charges of about $40 million in 2026, treated as special items and excluded from adjusted earnings.
Kesner Idalene Fay reported acquisition or exercise transactions in this Form 4 filing.
Duke Energy director Idalene Fay Kesner reported a routine equity compensation transaction. On July 2, 2026, she received 266 Director Savings Plan Restricted Stock Unit deferrals, each tied to Duke Energy common stock on a 1-for-1 basis at a reference value of $129.60 per unit.
These units are generally payable upon her termination of service and are held directly. After this award and an adjustment to include previously omitted units, her aggregate Director Savings Plan restricted stock unit holdings total 15,191 units, all representing deferred rights to receive common shares rather than an open-market purchase.
Duke Energy EVP and Chief Customer Officer Alexander J. Weintraub reported routine plan-related movements in his Duke Energy interests. A discretionary transaction under Rule 16b-3(f) involved 394 shares of common stock held indirectly through a 401(k) plan at $123.81 per share, bringing his indirect 401(k) holdings to 3,011 shares.
He also reported a discretionary transaction in the Executive Savings Plan, showing 3,265 phantom stock units at $124.56 per unit, each economically equivalent to one share of Duke Energy common stock and generally settled six months after termination of service. Separately, he holds 12,187 shares of common stock directly, with no open-market purchases or sales indicated.
Duke Energy director and chair Theodore F. Craver Jr. reported a bona fide gift of 2,402 shares of Common Stock on May 18, 2026. The filing describes this as a transfer from directly held shares to a joint trust, so it does not reflect a market sale.
After the transfer, Craver reports 19,193 Duke Energy shares as directly owned, which now includes shares held through the joint trust. The transaction is a non-cash internal reallocation of ownership rather than a change in his overall economic exposure to the stock.
Duke Energy Corporation reported the final voting results from its Annual Meeting of Shareholders held on May 7, 2026. All nominated directors were elected, generally receiving between about 89% and over 99% of votes cast in favor, indicating broad shareholder support for the existing board.
Shareholders also approved three key management proposals. Deloitte & Touche LLP was ratified as independent auditor for 2026 with 639,757,086 votes for and 28,434,117 against. The advisory vote on named executive officer compensation passed with 496,884,668 votes for and 26,030,663 against. A management proposal to amend the certificate of incorporation to eliminate supermajority voting requirements received 516,664,589 votes for, representing 66.39% of shares outstanding, and therefore failed to meet the required 80% approval threshold.
Duke Energy executive Louis E. Renjel reported an open‑market sale of 3,500 shares of Common Stock at $125.15 per share. After the sale, he holds 21,415 shares directly and 914 shares indirectly through a 401(k) stock fund, according to the Form 4.
Duke Energy director Jeffrey B. Guldner reported a compensation-related equity award. He acquired 1,602 Director Savings Plan restricted stock unit deferrals at a reference value of $124.87 per unit, each convertible into one share of Duke Energy common stock.
These units are generally payable upon his termination of service. Following this grant, his reported balance in this plan is 1,022 restricted stock unit deferrals. The transaction reflects an award or other acquisition rather than an open‑market stock purchase or sale.
