The Thesis
AES Corporation is a power generation business that builds and operates the massive electricity infrastructure needed to run modern cities and AI data centers. The company generated $12.28 billion in revenue last year, a slight decrease from the prior year as it aggressively sold off older fossil fuel assets. The ongoing shift from coal-fired power plants to a carbon-free portfolio is the structural change that defines the current investment case.
If you own AES, you are betting on four specific things at once.
In our view, the market is significantly underestimating the value of AES Corporation's position as a preferred power provider for the AI boom. The massive gap between the current price and the value of its contract backlog suggests investors are overly focused on past debt issues rather than future cash flows. The case for owning this only gets stronger if the company can prove it can build its renewables backlog faster than expected. We think AES is one of the cleaner ways to own the massive growth in electricity demand coming this decade.
Numbers at a Glance
What does it do?
AES Corporation is a mature business that earns money by generating electricity and selling it through long term contracts to utilities and corporate giants. The company operates in two main ways. First: it owns regulated utilities in the United States that have a legal monopoly to deliver power to homes and businesses in exchange for a set profit rate. Second: it builds massive wind, solar, and battery projects globally. These projects sell power to big tech companies and factories through 20 year agreements called Power Purchase Agreements. These contracts provide steady cash flow because the price is locked in for decades.
Where does revenue come from?
Most revenue comes from selling electricity to a mix of everyday utility customers and large corporate buyers across the globe. The business is split between regulated utilities in Ohio and Indiana, renewable energy projects, and traditional energy infrastructure. While the company operates in several countries, it is increasingly focusing its growth on the United States renewables market.
Revenue Breakdown
Revenue by Geography
Who are its customers?
AES Corporation serves millions of residential utility customers and a growing list of hyperscale technology companies. At its US utilities, the company provides essential electricity to roughly 527,000 customers in Indiana and 665,000 customers in Ohio. In its renewables business, it has signed contracts for 4 gigawatts of power specifically with data center operators. These "hyperscaler" customers are the primary engine for new growth as they search for carbon free energy to power AI workloads. The total backlog of signed but not yet built projects now stands at 11.1 gigawatts.
What gives it staying power?
The company has staying power because it operates essential infrastructure protected by long term legal contracts. Electricity is a non discretionary product with no substitutes. In regulated markets: competitors are legally barred from entering. In the renewables market: 20 year contracts create high switching costs and guaranteed revenue for the life of the equipment.
Where is it headed?
The company is headed toward a future where it is entirely carbon free and serves as the primary energy partner for the tech sector. Management is spending billions to shut down coal plants and replace them with wind and solar farms. If this works: AES will have a cleaner balance sheet and much more predictable earnings. The goal is to reach a 100% carbon free portfolio within the next decade.
AES Corporation is seeing a massive jump in earnings as new renewable projects come online to offset the sale of older assets. While total revenue has stayed relatively flat at around $12 billion, the quality of that revenue is improving. Net income more than doubled in the most recent quarter as the company moved toward higher margin green energy.
The company is currently in a heavy investment phase where free cash flow is deeply negative due to massive construction spending. Free cash flow was negative $4.64 billion last year because the company is building out a record backlog of wind and solar projects. This gap is intentional: management is trading current cash for decades of future contract revenue.
The balance sheet is heavily leveraged with a debt to equity ratio of 7.01 times. This high debt load reflects the capital intensive nature of building power plants and utilities. The company manages this by selling off older businesses to fund new growth without issuing too much new stock.
AES Corporation is a business in transition that is finally starting to show the profit potential of its green energy pivot.
The renewables backlog is growing rapidly with 2.9 gigawatts of new projects completed year to date. This proves the company can actually build the projects it signs on paper. Management is on track to add a total of 3.2 gigawatts of operating capacity by the end of the year.
The massive debt load remains the single biggest risk if interest rates stay high for a long period. The company needs constant access to cheap capital to build its multibillion dollar power projects. If borrowing costs rise significantly: the profit margins on new renewable contracts will shrink.
The global power industry is a multi trillion dollar market undergoing a massive structural shift toward carbon free generation. The US renewables market is roughly $300 billion today and is growing fast as tech giants demand 24/7 green power. The industry is shifting from a commodity price race into a race for reliability and land access. Pricing power is high for companies that can guarantee energy delivery at specific times. AES Corporation is a major challenger that has carved out a niche as the primary partner for AI data centers.
The competitive dynamic is rationally structured because the barriers to entry for large scale power generation are incredibly high. Building a power plant requires years of permits: billions in capital: and complex grid connections. Long term contracts act as a stabilizing force that prevents a race to the bottom on price.
NextEra Energy(NEE) is the most dangerous threat because its massive size allows it to buy equipment and borrow money cheaper than anyone else. Vistra(VST) is also a significant threat as it uses its existing nuclear plants to sign lucrative data center deals without needing to build new infrastructure. Brookfield Renewable(BEP) competes globally for the same corporate contracts AES pursues. NextEra's massive cost of capital advantage remains the biggest hurdle for AES to overcome.
AES is successfully holding its ground by specializing in complex energy solutions that tech companies prefer. The 11.1 gigawatt backlog of signed contracts is direct evidence that AES is winning its fair share of the market.
The primary source of protection is the regulatory moat at its US utilities combined with high switching costs from its long term contracts. Once a utility is granted a service territory: no other company can legally compete for those customers. The 20 year contracts signed with corporate buyers ensure revenue remains locked in for decades.
The numbers tell a story of a business with structural protection but heavy financial burdens. The 10.7% net margin shows that the underlying contracts are profitable: but the low ROIC of 3.1% reflects the massive debt used to build these assets. The combination of long term contracts and regulated monopolies creates a durable but capital intensive advantage.
The moat is currently stable as the company replaces expiring fossil fuel deals with even longer renewable contracts. The growing backlog of data center deals is the strongest signal that the competitive position is intact.

Capital Allocation Track Record
Andres Gluski has led a decade long transformation from a coal heavy utility to a renewables leader. While execution has been inconsistent at times: management has successfully secured a massive backlog of contracts with tech giants. The decision to sell off non core international assets to focus on US data center demand is the right strategic move. The management team is trustworthy but remains on a short leash regarding debt levels.
