AEP Q3 2026 Earnings: Data Center Load Grows, Rate Recovery Lags Costs

American Electric Power (AEP) reported third-quarter 2026 results on October 28, 2026, through its earnings release, Form 10-Q and earnings call. Operating earnings were $2.23 per share, up from $1.80 a year earlier [1]. Data center load kept lifting commercial electricity sales on a high base, but the profit gains were less repeatable than the headline growth suggests.

Three questions framed the quarter: whether data center load could keep growing sales and transmission-and-distribution profit against a high base, whether new rates in AEP's vertically integrated states could outpace rising costs, and whether transmission investment could produce profit growth with sustainable funding. The quarter confirmed the sales growth, but distribution-segment profit came mainly from riders. Vertically integrated profit jumped mostly on weather and new load, while rate revenue still grew less than costs. Transmission profit tracked asset growth, the capital plan expanded and leverage kept rising [2]. Taken together, AEP's growth runway is larger, the repeatable part of profit growth is smaller than the headline rate, and the timing of Texas load remains uncertain.

AEP is a regulated electric utility serving about 5.6 million customers in 11 US states, and it owns the largest transmission network in the country [1]. Its profit comes from vertically integrated utilities that own power plants and sell electricity, from AEP Ohio and AEP Texas, which earn delivery charges, and from a transmission holding company that recovers investment through federal formula rates.

Data center load keeps growing, but adds little to distribution profit

Third-quarter sales confirm that data center load is still connecting. Commercial sales in the transmission and distribution segment rose 18.0% year over year, even though the prior-year base had already grown 30.4%; commercial sales at the vertically integrated utilities rose 15.2% [1]. AEP attributes the commercial and industrial sales growth to new data processing load [2]. Incremental contracted load rose from 69 gigawatts to 84 gigawatts [1].

The sales growth contributed little directly to profit. Transmission and distribution operating earnings were $284 million, up 9.7% [1]. The segment's revenue gain came mainly from $141 million of rider revenue in Ohio and Texas, while weather-normalized commercial and industrial revenue rose only $10 million [2]. The main financial significance of the new load is that it supports future transmission and generation investment.

The timing of Texas load remains uncertain. ERCOT has paused Batch Zero classification and study work and will not authorize large loads to energize until verification is complete [2]. Management said the Texas investment plan focuses on reliability and includes only part of the required transmission build-out [3].

Vertically integrated profit jumps, but rate recovery still trails costs

Vertically integrated operating earnings were $721 million, up 25.8% [1]. The increase came mainly from $99 million of revenue from hotter weather, $45 million of weather-normalized commercial and industrial revenue and a $47 million decline in fuel and purchased power expense [2]. The weather benefit will not repeat, so the sustainable profit growth rate is below 25.8%.

Rate recovery still lagged costs this quarter. Base rate and rider revenue rose $261 million, while operations and maintenance, depreciation and interest together rose $293 million [2]. Even after excluding $28 million of catch-up depreciation tied to West Virginia, cost growth was still slightly higher. Rate settlements have been filed for SWEPCo in Texas and APCo in Virginia: the first would raise the allowed return on equity to 9.53%, and the second would move part of operating costs into riders. Both still need approval [3].

Transmission profit tracks asset growth as the capital plan expands and leverage rises

Transmission Holdco profit growth roughly matched its asset growth. The segment's operating earnings were $219 million, up 9.5% [1], and plant in service at September 30 was up 10.4% year over year [2]. AEP announced a $100.4 billion capital plan for 2027 through 2031 and expects rate base to grow from $87 billion to $162 billion by 2031 [3]. The company expects 2026 operating earnings of at least $6.55 per share and issued guidance of $6.75 to $7.05 for 2027 and $7.40 to $7.70 for 2028 [1].

The larger investment plan comes with rising funding pressure. Debt-to-total capital was 61.5% at September 30, up from 60.3% at the start of the year [2]. Management said about $55 billion of five-year operating cash flow will cover more than half of the investment and that the $22 billion of added capital requires only $5.2 billion of additional equity [3].

Conclusion

AEP's third quarter widened its growth runway, but the quality of profit conversion was weaker than the earnings growth implies. Transmission profit grew with assets, distribution profit relied on riders and vertically integrated profit was lifted by weather. Operating cash flow for the first nine months was $5.767 billion against $11.171 billion of investing outflows, so debt and equity still fill the gap [2]. The next tests are whether rate revenue covers cost growth in a normal-weather quarter, whether the two settlements are approved and whether Texas load enters the investment plan after ERCOT files its verification report on December 10 [3].
