DUK vs FE: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. DUK and FE share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined DUK and FE exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Duke Energy is a holding company for a group of regulated electric and gas utilities serving roughly eight and a half million electric customers across six states, including the Carolinas, Florida, Indiana, Ohio, Kentucky, and Tennessee, plus natural gas distribution to over a million customers. As a regulated utility, Duke earns an authorized return on the capital it invests in power plants, poles, wires, and pipes, so its profit grows largely as it grows its regulated asset base, or rate base, subject to approval from state utility commissions. This regulated model produces relatively stable, predictable cash flows that fund a long-running dividend, which is the core of the income case for the stock.

FirstEnergy Corp is one of the largest investor-owned electric systems in the United States, delivering electricity to roughly 6 million customers across Ohio, Pennsylvania, New Jersey, West Virginia, Maryland, and a sliver of New York. The company was formed in 1997 and expanded through the GPU (2001) and Allegheny Energy (2011) acquisitions. Today it operates almost entirely as a regulated wires business, organized into Regulated Distribution and Regulated Transmission segments, with more than 24,000 miles of transmission lines and a rate base of roughly $27 billion. The vast majority of earnings come from regulated activity under state and federal oversight, which produces relatively predictable cash flows.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• DUK drivers: Rate-base growth from a $103B capital plan; Data-center and large-load demand.
• FE drivers: Energize365 capital program and rate-base growth; Regulated, predictable earnings base.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Duke is highly capital-intensive and carries substantial debt to fund its build-out, which makes it sensitive to interest rates: higher rates raise its borrowing costs and tend to compress the valuations investors assign to regulated utilities, while also making bond yields more competitive with its dividend. For FE, firstEnergy carries a large debt load of roughly $28 billion and negative free cash flow, so it depends on continued access to capital markets and periodic equity issuance, which can dilute shareholders.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick DUK if you believe its drivers more; FE if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the DUK and FE guides.

DUK. As of late June 2026, DUK traded near the high-$120s per share with a market cap around ~$100 billion. The trailing P/E of roughly ~19x to ~20x is broadly in line with large regulated-utility peers, reflecting steady but moderate earnings growth rather than the higher multiples of faster-growing sectors. Revenue for full-year 2025 was about ~$31.8 billion, and Q1 2026 adjusted EPS was ~$1.93, up from ~$1.76 a year earlier. Figures are approximate, drawn from the Q1 2026 release and public market data, and move with the share price.

FE. FirstEnergy trades around 18 times forward core earnings, roughly in line with regulated-utility peers, reflecting steady but modest growth expectations. Q1 2026 core earnings rose about 7.5% year over year to $0.72 per share, and management reaffirmed full-year guidance with more growth weighted to the second half. Valuation and debt levels are the two figures most worth watching given the heavy capital program.

Headline figures (approximate, 2026-06-27): DUK shows revenue (ttm) ~$31.8B, adjusted eps guidance (fy2026) ~$6.55 to ~$6.80, adjusted eps growth target ~5% to ~7% per year through 2030, dividend yield ~3.4%; FE shows market cap ~$28 billion, share price ~$49, revenue (ttm) ~$14 billion, 2026 core eps guidance ~$2.62 to $2.82.

DUK and FE are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined DUK and FE exposure against your real portfolio. It is not an investment adviser.
