Mizuho reiterates American Electric Power stock rating at Neutral

The article reports Q3 2026 EPS of $2.23 versus Street estimates of $2.04, up approximately 24% year over year, and says AEP raised its EPS CAGR guidance through 2031 from 9%+ to 10%+. AEP added about 15 GW of contracted load, bringing total contracted load to 84 GW, and plans $100 billion in capital spending over five years; Mizuho maintained Neutral with a $135 price target. The article later gives conflicting Q3 figures—EPS of $1.80 versus a $2.02 estimate and revenue of $6.01 billion versus $6.57 billion—so the reported results are inconsistent.

Analysis

The investment case hinges less on headline EPS than on whether contracted data-center demand converts into energized, rate-base-supporting load quickly enough to earn returns on a very large construction program. “Contracted” gigawatts are not equivalent to near-term billed revenue: connection timing, customer concentration, cost allocation, and regulatory approval determine whether load growth offsets financing costs and rate-base lag. If investment precedes load or regulators resist shifting infrastructure costs to customers, AEP could face weaker returns and affordability-driven pushback. Weather and tax benefits also make reported earnings a poor stand-alone guide to recurring growth.

There is a material source-data conflict: the article gives two different Q3 EPS figures and opposite conclusions versus estimates. Treat the earnings beat and resulting estimate revisions as unverified until reconciled with AEP’s release and operating EPS bridge; do not trade the headline on this evidence alone.

Over the next 1–3 months, watch the earnings reconciliation, financing plan, regulatory outcomes, and milestones for bringing Ohio data-center load online. Over 6–18 months, the key test is whether actual load additions and allowed returns keep pace with capital deployment. The bullish thesis weakens if guidance or core operating EPS is cut, projects are delayed, or regulators disallow recovery; it strengthens with verified load energization and timely cost recovery. Given valuation concern and Street estimates reportedly near guidance midpoints, upside may require execution rather than another guidance raise.

Key Decisions for Investors

• Do not add AEP on the reported EPS surprise until the conflicting Q3 figures are reconciled against the company filing and recurring operating EPS bridge.
• For existing exposure, hold only if comfortable with regulated-capex execution risk; consider trimming strength rather than extrapolating contracted gigawatts directly into earnings.
• Set an alert for evidence of data-center load energization, customer-funded infrastructure, and regulatory cost recovery over the next 1–3 months; these are more decision-useful than headline contract capacity.
• Reassess if AEP cuts operating EPS guidance, delays major load connections, or encounters adverse rate-case treatment; a verified beat in recurring earnings plus on-time load conversion would invalidate the cautious stance.
