What Duke Energy does
Duke Energy is a Charlotte, North Carolina-based energy holding company founded in 1904. It operates regulated utilities in two segments. Electric Utilities and Infrastructure generates, transmits, distributes and sells electricity to customers across the Southeast and Midwest, and sells power wholesale to municipalities, electric cooperatives and other load-serving entities. Its generation mix includes nuclear, natural gas, coal, hydroelectric, oil and renewables. Gas Utilities and Infrastructure distributes natural gas to residential, commercial, industrial and power-generation customers. It also invests in pipeline transmission, natural gas storage and renewable natural gas projects. Together, the two segments make Duke a large, rate-regulated US utility whose earnings depend on its electric and gas infrastructure.

What is Duke Energy worth?
On an owner-earnings DCF, Duke Energy's most-likely value is about $13 versus a recent price near $117 (89% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$8) with a margin of safety — so the honest verdict here is “Stretched — richly priced.” Fair value earns its keep only at the extremes, not in the wide middle.
Today's $117 is above even the optimistic Bull case ($16) — the market expects faster, longer growth than modeled here. Expensive unless that extra growth actually shows up.
⚠ High leverage — net debt is 194.3× annual cash flow. Net debt is subtracted from this fair value, but refinancing at higher rates, principal timing, and share dilution aren’t modeled — the equity can be worth far less if cash flow weakens.
⚠ Capital-intensive — this business reinvests heavily, so free cash flow runs well below its earnings. Fair value here is built on free cash flow, which understates owner earnings for reinvestment-heavy companies — read it as conservative.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
