AEP vs EXC: Which Is the Better Buy in 2026?
Last updated November 2026
Short answer
AEP is the larger of the two ($71.10B market cap): the incumbent the market prices for continued execution (18.96x forward earnings, beta 0.44). EXC is the smaller challenger ($47.97B), cheaper on forward earnings (15.30x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
AEP vs EXC: the tie-breaker metrics
Same yardstick, side by side (as of November 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.
| Metric | AEP | EXC | What it tells you |
|---|---|---|---|
| Market cap | $71.10B | $47.97B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 18.96 | 15.30 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 21.34 | 18.11 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.44 | 0.34 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 64% of range | 61% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.17 | 1.59 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: EXC is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how AEP and EXC affect your concentration
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. AEP and EXC 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 AEP and EXC 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.

What does American Electric Power Company (AEP) do?
American Electric Power Company is one of the largest regulated electric utilities in the United States, serving about 5.6 million customers across 11 states and operating roughly 40,000 miles of transmission lines, among the most extensive networks in the country. Its business is built on regulated generation, transmission, and distribution, meaning state and federal regulators set the rates it can charge and approve the returns it earns on invested capital. That structure makes AEP's earnings relatively predictable compared with cyclical companies, but it also caps how fast profits can grow and ties results to regulatory decisions.
What does Exelon (EXC) do?
Exelon is one of the largest US utility companies by customer count, serving roughly 11 million customers through six fully regulated transmission and distribution utilities: Commonwealth Edison (ComEd) in Illinois, PECO in Pennsylvania, Baltimore Gas and Electric (BGE) and Potomac Electric Power (Pepco) in the Mid-Atlantic, plus Delmarva Power and Atlantic City Electric. After spinning off its competitive generation business (now Constellation Energy) in 2022, Exelon is a pure wires-and-poles operator, meaning it delivers power and gas rather than generating it, and earns regulated returns on the infrastructure it builds.
AEP vs EXC: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- AEP drivers: Data center and large-load demand; The $78 billion capital plan.
- EXC drivers: Rate-base growth and the capital plan; Data-center and high-density load growth.
Which fits which kind of investor
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: The main risk for a regulated utility is regulatory: AEP operates across 11 state jurisdictions, and unfavorable rate-case outcomes or disallowed costs can limit the returns it earns on its large capital plan. For EXC, as a capital-intensive regulated utility, Exelon is sensitive to interest rates, since higher rates raise financing costs and can make the dividend yield less competitive versus bonds.
AEP or EXC: which should you pick?
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 AEP if you believe its drivers more; EXC 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 AEP and EXC guides.
AEP vs EXC: the full fundamentals
AEP. At about 18 times forward earnings AEP trades at a premium to many slower-growing utility peers, a price that reflects its rate-base growth and data center pipeline. Analysts expect operating EPS of about $6.39 in 2026 and $6.87 in 2027, roughly 7% growth a year, in line with the company's high-single-digit target. Q3 2026 results on October 28 carry a consensus near $2.01 per share; for a regulated utility, allowed returns, interest rates and whether large-load demand converts to firm contracts matter more than any single quarter.
EXC. Exelon trades around 16 times trailing and 14 times forward earnings, slightly below where it sat in mid-2026 and modestly below many regulated-utility peers, which leaves the dividend yield near 3.9%. The second-quarter miss was small, and full-year consensus of about $2.86 sits inside the $2.81 to $2.91 guidance range; the October 30 report is the next check. Valuation largely turns on rate-base growth expectations and the interest-rate backdrop.
Headline figures (approximate, October 2026): AEP shows share price / market cap ~$126.64 (Oct 16, 2026), ~$69 billion, revenue (ttm) ~$22.8 billion; Q2 2026 ~$5.45 billion, up ~7%, q2 2026 operating eps ~$1.36 (below the ~$1.48 consensus), net income (ttm) ~$3.1 billion, GAAP EPS ~$5.77; net margin ~14%; EXC shows revenue (ttm) ~$25.3B; Q2 2026 ~$5.97B, up ~10%, net income (ttm) ~$2.78B; net margin ~11%, adjusted eps Q2 2026 $0.43 vs ~$0.45 expected; 2026 guidance ~$2.81-$2.91, consensus ~$2.86, p/e ~15.9x trailing, ~14.2x forward.
The bottom line: AEP vs EXC
AEP and EXC 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 AEP and EXC exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AEP and EXC?
+
American Electric Power Company is one of the largest regulated electric utilities in the United States, serving about 5.6 million customers across 11 states and operating roughly 40,000 miles of transmission lines, among the most extensive networks in the country. Exelon is one of the largest US utility companies by customer count, serving roughly 11 million customers through six fully regulated transmission and distribution utilities: Commonwealth Edison (ComEd) in Illinois, PECO in Pennsylvania, Baltimore Gas and Electric (BGE) and Potomac Electric Power (Pepco) in the Mid-Atlantic, plus Delmarva Power and Atlantic City Electric. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is AEP or EXC the better stock?
+
Neither is universally better. AEP is the larger incumbent; EXC is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, AEP or EXC?
+
On forward P/E (as of November 2026), AEP trades at 18.96x and EXC at 15.30x, so EXC is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both AEP and EXC?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of AEP vs EXC?
+
AEP: The main risk for a regulated utility is regulatory: AEP operates across 11 state jurisdictions, and unfavorable rate-case outcomes or disallowed costs can limit the returns it earns on its large capital plan. Financing risk is significant because a roughly $78 billion plan requires heavy debt and equity issuance, on top of about $53.5 billion of existing debt, exposing the company to higher interest rates, a rising cost of capital, and potential shareholder dilution. The data center demand thesis is a risk as well as an opportunity: if forecast large-load additions slow, are delayed, or fail to convert to firm contracts, the case for expanded spending weakens. New generation technologies add execution risk: the Wyoming fuel cell plant depends on Bloom Energy equipment and planned carbon capture, and the Mainspring generators are a newer technology at utility scale. Earnings can also miss, as the Q2 2026 operating EPS of $1.36 against a $1.48 consensus showed, and several brokers trimmed price targets in October 2026. Utilities also carry operational and physical risks, including storms, wildfires, fuel and commodity costs, and the pace of the energy transition. As a slower-growth income stock, AEP can also underperform in strong bull markets when investors favor higher-growth names. EXC: As a capital-intensive regulated utility, Exelon is sensitive to interest rates, since higher rates raise financing costs and can make the dividend yield less competitive versus bonds. Earnings depend heavily on constructive decisions from multiple state commissions and federal regulators across Illinois, Pennsylvania, Maryland, New Jersey, Delaware, and Washington DC, so unfavorable rate cases or allowed-return cuts are a real risk. The large capital plan requires ongoing debt and equity issuance, which can pressure the balance sheet and dilute shareholders. Growth is inherently slow relative to non-regulated companies, and much of the anticipated data-center demand is still projected rather than realized. Weather, storm costs, and policy shifts add further variability. Leverage is high even by utility standards, with about $52.7 billion of debt against roughly $1.8 billion of cash and trailing free cash flow of about negative $2.7 billion, so the capital plan depends on continued access to debt and equity markets.
