American Electric Power (AEP)

Servicios públicos / Electricidad (generación, transmisión y distribución, 11 estados)

One of the largest US electric utility holding companies: four regulated segments (Vertically Integrated Utilities, Transmission and Distribution, AEP Transmission Holdco, and the competitive Generation & Marketing) across eleven states, with data-center demand as the driver of a five-year, US$78,000M capital plan (AEPTCo's transmission rate base grew +16.7% in 2025, supported in part by data-center tariff contracts with terms of up to twenty years and take-or-pay minimums). But at ~$124 the base 5-year return runs ~$133 (+1%/year price, +5% with the dividend): Fairly valued — a solid regulatory moat trading at 22× earnings that, already clean of the 2025 nonrecurring regulatory benefit, are growing at the normal pace of a regulated utility.

Moat Compounder estimates the intrinsic value of American Electric Power (AEP) at $133 per share on a five-year horizon. With the stock at $124.23 at 2026-10-12 close, the expected total return is 4.9% per year: fairly valued. The analysis draws on 10-K FY2025 and XBRL companyfacts (historical series through Q1 2026). Analysis dated 2026-07-30.

The essentials

  • A holding of four regulated segments (Vertically Integrated Utilities ~57% of external revenue, Transmission and Distribution ~28%, competitive Generation & Marketing ~12%, AEP Transmission Holdco barely ~2% of external revenue but 32% of consolidated attributable income) serving more than five million retail customers in eleven states, with territorial franchises and cost-of-service tariffs approved jurisdiction by jurisdiction (authorized ROE ranges from ~9.25% to ~10.50% depending on the state or FERC line).
  • The growth engine is data center and large industrial load interconnection: the formula rate base of the State Transcos (AEP Transmission Holdco, FERC-regulated) rose from $11,400M to $13,300M in 2025 (+16.7%), backed by tariff contracts of up to twenty years with minimum take-or-pay of up to 90% of contracted load, already filed in eight jurisdictions. The sale of a 19.9% non-controlling interest in Midwest Transmission Holdings to KKR/PSP for $2,820M (closed in June 2025) recycled capital toward that plan, recorded entirely in equity, with no gain in net income.
  • At ~$124 it trades at 22× trailing-twelve-month net income attributable through June 2026, which no longer contains the $480M nonrecurring benefit from the FERC's June 2025 order on the treatment of NOLCs in transmission formula rates: that item was recorded in the second quarter of 2025 and fell out of the window, and the non-GAAP reconciliation now runs the other way (trailing-twelve-month operating earnings $3,234M against $3,141M GAAP, i.e. $93M of net charges in the first half of 2026). Against the 2026 GAAP guidance AEP raised on Jul 30 ($6.16-$6.46 per share) and at 22× trailing-twelve-month earnings, the base return (+5% total) falls short of the average return on stocks — Fairly valued.

Total return at 5 years: 4.9%/year = 1.4% appreciation + 3.5% dividend. The target price ($133) is ex-dividend; the $22 in dividends collected over 5 years are added separately.

By both methods, the value today (DCF $169 · Multiples $126) exceeds the market price ($124).

Pillars of the analysis

The verdict — today vs 5 years

Today — fairly valued: at $124 trades ~1.6% below its value discounted to today (~$126); the discount is positive but does not reach the margin of safety we require (≥38%).

At 5 years — En valor: the target price ($133) plus dividends yield between the 4% floor and the 10% average return — a reasonable return, though without the margin of a great investment.

The bridge: the return at 5 years exceeds the risk-free rate (4.5%) — but the discount does not reach the required margin of safety (≥38%). To require a 15% annual return, it would need to be bought at ~$81.

Thesis

The business

AEP is one of the largest electric utility holdings in the US: four regulated segments (plus the small competitive Generation & Marketing) with a solid regulatory moat and a privileged position as the mandatory interconnection point for data center demand that today drives the utility sector, reinforced by tariff contracts of up to twenty years with minimum take-or-pay. The FERC-regulated transmission rate base (AEPTCo) grew +16.7% in 2025 and already contributes 32% of consolidated attributable income — the cleanest and most verifiable indicator of capital plan acceleration.

The valuation

A utility is valued on P/E over net income attributable to common shareholders: the GAAP line the earnings release itself reconciles against its non-GAAP operating earnings. The trailing twelve months through June 30, 2026 is $3,141M (FY2025 $3,580M + first half of 2026 $1,587M − first half of 2025 $2,026M, from the 10-Q filed July 30, 2026), against $2,208M in FY2023. That figure is already clean of the $480M nonrecurring benefit from the FERC's June 2025 order on the treatment of NOLCs —recorded in the second quarter of 2025, i.e. outside the window— and in fact runs $93M below non-GAAP operating earnings for the same period ($3,234M), on net charges in the first half of 2026. Anchoring year 1 by levels to the guidance the company raised on Jul 30 ($6.16-$6.46 GAAP EPS, with the +1yr window closing in June 2027) and growing afterward from the reaffirmed 7-9% floor through 2030, with the multiple compressing from 22× today to ~16× (within the regulated-utility band, 15-18×), gives ~$133/share → price CAGR +1%, +5% with the dividend (3.1%).

The margin of safety

It trades close to intrinsic value, far from the required margin of safety. The base return (+5% total: +1%/year price and +3% dividend) falls short of the average return on stocks (~10%, the method's bar). At ~$124, the value brought to today at the risk-free rate leaves a small or nil discount. The verdict is Fairly valued: the business is solid and the regulatory moat real, but the price already prices in much of the enthusiasm over data-center demand, and trailing-twelve-month earnings —already without the 2025 regulatory boost— leave the entry multiple at 22×.

What to watch

Three things. Whether the second half of 2026 delivers the acceleration the guidance assumes: the first half grew just +1.0% in operating earnings per share against a full year guided to +7.3%, meaning all of the year's improvement lies ahead — the assumption year 1 of the model depends on. Whether data-center demand materializes and regulators recognize the associated capex in rates (the structural disconfirmer: the filing warns the plan could exceed the sector's historical financing experience, and the ongoing reform of PJM's capacity market could alter cost allocation in Ohio). And the nuclear risk at the Cook plant (I&M) plus pending challenges to transmission formula rates before the FERC.
