Key Takeaways:

  • American Electric Power (AEP) raised its capital investment plan to $78 billion, citing surging data center electricity demand as the primary driver, and Q1 2026 revenue beat estimates by around $340 million.
  • Q1 2026 revenue of $6.02 billion topped analyst estimates of $5.68 billion, and GAAP EPS rose 7.3% to $1.61, demonstrating consistent execution on the company’s regulated utility growth strategy.
  • AEP stock could rise from $137 to around $160 per share by December 2028, based on around 8% annual revenue growth, 28% operating margins, and a 19.0x P/E multiple.
  • That implies a 16.6% total return and an annualized return of around 6% over the next 2.6 years, plus AEP’s 2.8% dividend yield.

What Happened?

American Electric Power (AEP) delivered a strong Q1 2026 earnings report in early May that impressed investors and analysts alike. Revenue of $6.02 billion beat the consensus estimate of $5.68 billion by around 6%, and GAAP EPS rose 7.3% year over year to $1.61.

The company also raised its capital investment plan to $78 billion, citing extraordinary growth in electricity demand from data centers as the primary justification for the spending increase. AEP is one of the largest electric utilities in the United States, serving more than 5 million customers across 11 states.

Data center demand is rapidly reshaping AEP’s growth story. The company announced a partnership with SoftBank to develop a massive gas-fired data center campus in Ohio that would require significant new electricity infrastructure.

AEP Ohio is also committing $4.2 billion to Appalachian infrastructure upgrades, and the company won approval to acquire a 918-megawatt natural gas plant through its Indiana Michigan Power subsidiary. These moves reflect AEP’s strategy to position regulated electricity infrastructure at the center of the AI data center buildout.

Here’s why AEP stock could still deliver solid returns through 2028 as its data center strategy translates into regulated rate base growth and predictable earnings expansion.

What the Model Says for AEP Stock

We analyzed the upside potential for American Electric Power stock using valuation assumptions based on its regulated electricity rate base growth, surging data center demand across its service territory, and steady dividend income that supports total return.

Based on estimates of around 8% annual revenue growth, 28% operating margins, and a normalized P/E multiple of 19.0x, the model projects American Electric Power stock could rise from $137 to around $160 per share.

That would be a 16.6% total return, or an annualized return of around 6% over the next 2.6 years.

AEP Stock Valuation Model (TIKR)

Our Valuation Assumptions

TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.

Here’s what we used for AEP stock:

1. Revenue Growth: 8%

AEP reported Q1 2026 revenue of $6.02 billion, growing around 10% year over year. The company’s regulated utility model means revenue growth is tied primarily to rate base expansion, which reflects the total value of utility infrastructure eligible for a regulated return. The $78 billion capital plan announced by management signals that the rate base is set to grow significantly over the next decade.

Based on analysts’ consensus estimates, we used around 8% annual revenue growth. This reflects the strong tailwinds from data center electricity demand in AEP’s service territories in Ohio, Indiana, Texas, and other states. Regulated utilities earn approved returns on capital investments, so larger capital plans generally translate directly into higher future revenue.

The SoftBank data center campus partnership and the broader AI infrastructure buildout in Ohio represent new large-load customers that should drive above-average electricity consumption growth. So the 8% revenue growth assumption appears grounded in visible, contracted demand rather than speculative projections.

2. Operating Margins: 28%

AEP’s LTM EBIT margin is around 25.2%, and gross margin is around 47.5%. As a regulated utility, AEP’s operating margins are relatively stable because regulators approve the rates customers pay and the returns shareholders earn. This provides more margin predictability than most industries, even if upside is also limited by regulatory frameworks.

Based on analysts’ consensus estimates, we used 28% operating margins. This reflects a modest improvement from current reported levels as the company completes rate case proceedings and earns approved returns on its growing capital investment. Regulatory lag, meaning the time between making an investment and earning a return on it, is the main timing risk.

The company’s net debt to EBITDA ratio is around 5.4x, which is typical for capital-intensive regulated utilities. But the $78 billion capital plan will require continued access to debt markets and possibly equity issuance to fund growth, and that additional financing cost is embedded in the margin assumptions.

3. Exit P/E Multiple: 19x

AEP currently trades at a forward P/E of around 21.3x, slightly above the exit multiple used in our model. This premium reflects the strong data center demand narrative and investor enthusiasm for utilities with visible growth catalysts. But regulated utilities rarely sustain P/E multiples above 20x for extended periods, so moderate compression back to 19x over time is a reasonable assumption.

Based on analysts’ consensus estimates, we maintained a 19.0x exit P/E. This is below the current trading multiple but still above the long-term utility sector average. It accounts for the possibility that the premium valuation partially fades as the broader utility sector becomes more competitive for growth-oriented capital.

The 2.8% dividend yield provides a meaningful income cushion at current prices. So the combination of the 6% annualized stock price return and the dividend yield brings total annualized returns closer to 9%, which is a reasonable outcome for a regulated utility with visible growth drivers.

What Happens If Things Go Better or Worse?

Different scenarios for AEP stock through 2030 show varied outcomes based on data center electricity demand growth, rate case approvals, and capital deployment success (these are estimates, not guaranteed returns):

  • Low Case: Regulatory delays and slower data center build-out limit rate base growth → around 4% annual returns
  • Mid Case: Data center demand stays strong, and rate case approvals support the capital plan → around 6% annual returns
  • High Case: Accelerating data center expansion and favorable regulation drive above-target earnings growth → around 8% annual returns
AEP Stock Valuation Model (TIKR)

Going forward, American Electric Power’s trajectory will be shaped by two forces working in its favor: the structural shift toward data center electricity demand and the company’s well-positioned service territory in Ohio and surrounding states.

RMD has already delivered strong returns over the past year, so near-term upside is more modest, but the dividend income, regulatory stability, and $78 billion capital plan provide a compelling foundation for steady compounding. Investors in AEP are essentially betting on electrification, AI infrastructure growth, and the ability of regulated utilities to earn predictable returns on growing capital bases over many years.
