Where American Electric Power's money goes
- 01
Revenue grew more than twice as fast as fuel costs
Revenue rose 13.66% while fuel and purchased power rose 5.35%, so the growth came from what AEP earns on, not what it passes through.
Why it matters
Purchased electricity, fuel and other consumables were $2.09B against $1.98B a year earlier, up 5.35%. Revenue rose 13.66% to $6.83B from $6.01B. The fuel line fell to 30.55% of revenue from 33.0%, and operating margin widened to 26.5% from 25.3%.1
AnalysisFuel and purchased power are normally recovered from customers at cost, with no markup. When revenue grows well ahead of that line, the extra revenue is mostly the part of the bill that recovers depreciation, operating costs and the allowed return on invested capital. Analysis: that is the higher-quality kind of utility revenue growth, because it tracks the regulated asset base rather than commodity prices.
AnalysisThe caveat runs the other way too. A margin widened by a slower fuel line can narrow again if gas and coal prices rise, even with no change in the underlying return, because pass-through revenue inflates sales without adding profit.
- 02
Interest takes a steady third of operating profit
Interest expense of $606M was 33.4% of operating income, the same share as a year earlier, so lenders grew in step with profit.
Why it matters
Operating income rose 19.05% to $1.81B from $1.52B. Interest expense rose 19.06% to $606M from $509M. Measured against operating income, interest was 33.4% in both quarters, and 8.87% of revenue this quarter.1
AnalysisAnalysis: the matching growth rates are what a debt-funded build looks like. New plants and lines enter the rate base and lift operating income, and the borrowing that paid for them lifts interest by about as much. The operating gain did not widen the share left for shareholders before tax; pretax income rose 17.89%, a little slower than operating income.
AnalysisThe ratio is a useful gauge to follow. If the allowed return on new investment stays above the cost of the debt raised for it, the share holds; if borrowing costs rise faster than rates are reset, interest would take a larger slice.
- 03
A lower tax take pushed net profit past pretax growth
Tax fell to 9.5% of pretax income from 12.4%, so net income rose 21.8% while pretax income rose 17.89%.
Why it matters
Income tax expense fell 10.07% to $125M from $139M while income before tax rose to $1.32B from $1.12B. Tax took 9.5% of pretax income against 12.4% a year earlier. Net income rose 21.8% to $1.22B, ahead of pretax income's 17.89%.1
Per share, part of that gain was shared with new holders. Earnings attributable to AEP common shareholders rose to $1.19B from $972M, while diluted shares rose to 550.1 million from 538.0 million, so diluted earnings per share went to $2.16 from $1.81.1
AnalysisThe filing excerpt does not explain the lower tax take. Analysis: utilities often benefit from tax credits tied to their generation and from the regulatory treatment of deferred taxes, and these can vary between quarters, so this quarter's rate should not be read as a lasting level.
- 04
Operating profit nearly doubled since FY2018 on modest sales growth
Operating income in FY2025 was 1.98 times FY2018's while revenue rose only to $21.88B from $16.20B, lifting operating margin to 24.3% from 16.6%.
Why it matters
Operating income was $5.32B in FY2025 against $2.68B in FY2018. Revenue was $21.88B against $16.20B. Operating margin rose to 24.3% from 16.6%, and this quarter's was 26.5%.1
AnalysisAnalysis: for a regulated utility, operating profit follows the capital it has invested and not yet depreciated, while revenue also carries fuel recovered at cost. A growing asset base raises profit, and the fuel portion of revenue does not, so margin climbs as the base grows. Depreciation and amortization, the recovery of that base, rose 16.61% this quarter to $1.03B, faster than revenue's 13.66%.

What it costs
The cost lines beneath operating income, each as a share of revenue, then the operating result.
Costs are reported by nature: what they are (food, labor, occupancy, personnel, marketing), not what they were for, so there is no cost-of-revenue line and no gross profit.

What holds American Electric Power's model up, and what could bend it
Competitive edge
Earnings that follow the investment base
Regulators set rates to recover costs plus a return on invested capital, so each completed plant or line raises the earnings base.
The detail
Depreciation and amortization rose 16.61% to $1.03B, equal to 56.6% of operating income, and the allowance for equity funds used during construction rose 37.29% to $81M. Both grow with the capital in service or under construction.1
AnalysisAnalysis: the advantage holds because the service area is a franchise. Competitors cannot build a second set of wires to the same customers, and the allowed return is set by regulators rather than by price competition.
The largest cost passes through at cost
Fuel and purchased power were 30.55% of revenue, the biggest cost line, yet commodity swings move revenue far more than profit.
The detail
Purchased electricity, fuel and other consumables were $2.09B against operating income of $1.81B. The line rose 5.35% while operating income rose 19.05%.1
AnalysisAnalysis: adjustment clauses let a regulated utility collect what it spends on fuel without a markup, so the cost a merchant generator would bear as risk is largely carried by customers' bills. The timing of recovery can still lag, which is a cash question more than a profit one.
Even the largest utility brings only 17.7% of revenue
Ohio Power, the largest operating company, brought in 17.7% of revenue, so no one state regulator decides most of the outcome.
The detail
By legal entity, Ohio Power reported $1.21B, 17.7% of consolidated revenue, Appalachian Power $1.13B, 16.6%, Indiana Michigan Power $894M, 13.1%, Public Service Company of Oklahoma $868M, 12.7%, SWEPCo $770M, 11.3%, AEP Texas $659M, 9.6%, and the transmission company AEPTCo $594M, 8.7%.1
AnalysisAnalysis: each operating company files its own rate cases with its own commission. A spread like this means one unfavorable decision moves a slice of the whole, not the whole.
What to watch
Debt and new shares fund the build
Interest rose 19.06% to $606M and diluted shares rose to 550.1 million, so capital costs arrive before all the new rates do.
The detail
Interest expense was $606M against $509M, 8.87% of revenue. Diluted shares averaged 550.1 million against 538.0 million. The quarterly report adds no new risk factors, stating there have been no material changes to those disclosed in the 2025 annual report.1
AnalysisAnalysis: what has to hold is that allowed returns on new investment stay above the cost of the capital raised, and that rate approvals arrive soon enough that the lag does not erode earnings per share.
A growing slice of earnings is construction income
Equity funds used during construction, non-cash income, were $81M, 6.8% of earnings to common shareholders against 6.1% a year earlier.
The detail
The allowance for equity funds used during construction rose 37.29% to $81M from $59M, faster than net income's 21.8%. Against earnings attributable to AEP common shareholders of $1.19B, it was 6.8%, up from 6.1% on $972M.1
AnalysisAnalysis: this income becomes cash only when projects enter service and their costs enter rates. A delay or a disallowance in a rate case would leave part of today's reported earnings without the recovery it assumes.
Other operating costs grew twice as fast as revenue
Other operation rose 28.82% to $1.03B against revenue's 13.66%, taking 15.05% of revenue, up 1.77 points on a year earlier.
The detail
Other operation was $1.03B against $798M. Maintenance rose 10.37% to $447M. Total expenses still grew more slowly than revenue, 11.83% against 13.66%, because the fuel line rose only 5.35%.1
AnalysisAnalysis: the filing excerpt does not break down the increase. Costs of this kind are recovered when rates are reset, so a sustained rise ahead of rate cases would show up as margin pressure in the periods between them.
