AES Corporation (AES)
Global C-corp pivoting to renewables: 34.7 GW gross capacity (54% renewables), FY2025 Parent FCF of $1,219M, 12.0 GW signed backlog, and ~$10.5B market cap.

Snapshot
The Developer Pivot Benchmark
AES is the C-corp case for a global generator exiting legacy coal and gas toward contracted renewables, valued on pipeline and Parent Free Cash Flow rather than a yieldco's CAFD (cash available for distribution). Gross owned and/or operated capacity was 34,740 MW at FY2025 year-end: 54% renewables, 29% gas, 15% coal, 2% pet coke and oil; the Renewables strategic business unit (SBU) operated 17,836 MW. Adjusted EBITDA still carries legacy fuel in the SBU split (Renewables 32%, Utilities 29%, Energy Infrastructure 39%).
AES does not file a consolidated contracted versus merchant percentage. The 10-K describes most generation under medium- or long-term power purchase agreements (PPAs) or short-term competitive-market sales. Use qualitative mix and SBU EBITDA split, not a fabricated PPA share.
Business Overview
AES spans US utilities, international generation, and a renewables platform scaling toward clean-energy sales. Signed backlog is 12.0 GW including 5.7 GW under construction. US Clean Energy development pipeline is 46 GW (10,961 MW operating and 3,031 MW under construction within that footprint). That backlog-versus-operating gap is the developer pivot in numbers: EBITDA today still carries coal and gas; growth capex targets renewables under LT PPAs.
Net debt was approximately $27.2 billion at 31 December 2025 ($29.5B gross debt less cash, restricted cash, short-term investments, and reserves per AES definition; calculated). Net debt divided by Adjusted EBITDA is ~9.5×, above the house >7× stretched screen for merchant-heavy books and above BEP's ~5.8×. High leverage funds development; Parent FCF is the cash metric that matters for equity distributions after project-level debt.
How the Economics Work
Renewables SBU capacity (17.8 GW) runs at wind and solar capacity factors in the house norms (34% wind, 24% solar planning; nuclear not relevant at AES scale). The capacity factor guide links nameplate MW to LTA MWh for backlog math: 1 GW solar at 24% delivers far fewer MWh than 1 GW nuclear at 91%, which shapes PPA revenue on new builds.
Parent FCF aggregates cash available at the holdco, the parent company sitting above the operating subsidiaries, after project debt service. At $1,219 million for FY2025 it is the C-corp analogue to yieldco CAFD; compare to Vistra Adj. FCFbG ($3,592M) and NRG FCFbG ($2,210M) on labelled bases, not on an invented CAFD line.
The PPA vs merchant guide hierarchy applies: without a filed split, use SBU EBITDA mix (Renewables 32%, Utilities 29%, EI 39%) and qualitative LT-PPA commentary rather than assigning a precise contracted percentage.
Valuation Framework
Computed EV/EBITDA on FY2025 figures was ~13.1× (enterprise value of roughly $37.7B, from market cap ~$10.5B plus net debt ~$27.2B, divided by $2,871M Adjusted EBITDA), as of June 2026. Alongside ~9.5× calculated leverage and legacy coal/gas MW, that multiple embeds pipeline optionality rather than pure contracted cash-flow quality.
12.0 GW signed backlog is balance-sheet growth; the same 46 GW US Clean Energy pipeline cited above is development optionality. House teaching mark $1.0–1.5M/MW for contracted US wind/solar applies to advanced MW until transaction comps replace it.
Key Risks
Leverage ~9.5×. Stretched on calculated net debt/EBITDA. Refinancing, project delays, or EBITDA miss bite equity before Parent FCF grows.
Legacy coal and gas. 15% coal and 29% gas by capacity still flow through Adjusted EBITDA until retired or sold.
Backlog execution. 5.7 GW under construction must reach COD under budget and with offtake intact, or the pipeline that today prices ahead of operating EBITDA converts into stranded capex instead.
No filed contract %. Do not import Brookfield's ~89% proxy; AES requires qualitative LT-PPA / competitive-market framing.
What the Screening Shows
Against the Renewables and IPPs Sector Primer thresholds:
- Capacity: 34.7 GW gross; 54% renewables. Renewables SBU 17.8 GW.
- Contract profile: Not filed; qualitative LT-PPA / competitive-market. SBU EBITDA mix only.
- Cash metric: Parent FCF $1,219M (not CAFD).
- Leverage: ~9.5× net debt ÷ Adj. EBITDA (calculated). Stretched band.
- Pipeline: 12.0 GW signed backlog; 46 GW US Clean Energy development pipeline.
AES is the C-corp pivot comp: renewables majority on capacity, legacy fuel still in EBITDA, pipeline priced ahead of CAFD-style payout clarity. The stock pairs Brookfield-like development narrative with Parent FCF and leverage that yieldcos avoid.
Renewables & IPPs Sector Primer
A multi-period DCF splits contracted PPA years from the merchant tail, pricing each off realised power price and term, then checks the value against spark spread and CAFD.
The Excel model is the primer's two archetype builds live across 10 sheets: a multi-period DCF with a contracted-or-merchant toggle, step-down discount rates for the PPA term and the merchant tail, a spark-spread build for the merchant case and a CAFD-and-payout bridge for the yieldco. Change the realised PPA price, the contracted discount rate or the merchant spread and the value per share moves; the premium and payout sheets update alongside it. It also splits the contracted premium into the part the pipeline explains and the part contract quality explains, splits the PV between contracted years and the merchant tail, and reads EV per kW on both archetypes.
