Company Description
Duke Energy Corporation 5.625% Junior Subordinated Debentures due 2078 (NYSE: DUKB) represent a specific class of securities issued by Duke Energy Corporation and listed on the New York Stock Exchange. According to Duke Energy’s SEC filings, these securities are identified as 5.625% Junior Subordinated Debentures due September 15, 2078 and trade under the symbol DUKB on the NYSE.
Duke Energy Corporation is described in its filings as a Delaware corporation. The debentures are included among the securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, alongside Duke Energy’s common stock (symbol DUK), certain preferred-related depositary shares (DUK PR A), and several series of senior notes (DUK 28A, DUK 34, DUK31A). This positioning in the capital structure, as reflected in the filings, distinguishes DUKB from Duke Energy’s common equity and senior notes.
The sector classification provided for DUKB is Electric & Other Services Combined. While the SEC filings focus on regulatory and governance matters at the Duke Energy corporate level, they confirm that DUKB is a listed security tied to Duke Energy’s broader activities in this sector. The junior subordinated nature of the debentures is reflected in the title used in the registration tables, which describe them as junior subordinated debentures rather than senior notes or equity.
In multiple Form 8-K filings, Duke Energy lists DUKB in the table of securities registered on the NYSE. These filings also show that Duke Energy is not characterized as an emerging growth company under SEC rules. The presence of DUKB in these filings indicates that the debentures are part of Duke Energy’s long-term financing arrangements and are tracked within its public reporting framework.
Investors researching DUKB stock are looking at a specific debt-like instrument rather than common equity. The SEC registration tables identify the security’s coupon rate (5.625%) and its long-dated maturity in 2078, which are central features of this class of debentures as disclosed in the filings.
