Duke Energy trades at a ~16% discount to the peer median on EV/EBITDA, yet the 2025 gross margin collapsed to 31.6% from 50.0% in 2024—despite modest revenue growth and steady EPS accretion—indicating possible cost pressures or one‑time items. Recent open‑market sales by the CEO and a senior EVP, combined with persistently negative free cash flow driven by heavy capex, temper the valuation appeal. The long‑term demand story around AI data centers provides a potential tailwind, but the picture is mixed enough to warrant a hold until margin trends stabilize or clearer catalysts emerge.
Unfavorable rate case outcomes
Regulatory disallowances could compress allowed ROEs and limit earnings growth, offsetting the benefit from a growing rate base.
Rising interest expense
The company carries $90.9B in total debt; sustained higher rates would pressure EPS and credit metrics, potentially leading to a downgrade.
Severe weather events
Hurricanes or other storms in its Southeast service territory can cause significant operating disruptions and one‑time repair costs.
Capex overruns & negative FCF
Annual capex of $14B already pushes free cash flow deeply negative; cost overruns on generation or grid projects could further strain liquidity and necessitate equity issuance.
