Prologis owns and leases warehouse and logistics buildings to companies that need space to store and ship goods. Its tenants include Amazon, Home Depot, FedEx, UPS, and Walmart, along with thousands of other businesses. Tenants sign multi-year leases and pay rent every month. When a lease expires, Prologis renews it at the current market rate, which has been higher than the old rate in every quarter since 2013. On top of rental income, Prologis manages $73.8 billion worth of properties on behalf of outside investors, collecting management fees for that service. The combination of steady rent, contractual rent increases, and fee income from partners forms a machine that compounds quietly over time. The diagram below traces where the money goes.

Five years of numbers tell a clear story about direction. Revenue grew from $4.8 billion in 2021 to $8.8 billion in 2025, nearly doubling in four years. Operating cash flow followed a similar path, rising from $3.0 billion in 2021 to a peak of $5.4 billion in 2023. The cash flow figure dipped slightly to $4.9 billion in 2024 and held near that level at $5.0 billion in 2025, even as revenue kept climbing. That gap between revenue growth and cash flow growth is worth noting. Debt has also grown every year, from $17.2 billion in net debt in 2021 to $33.9 billion by 2025. Prologis funds its expansion partly by borrowing, locking in long-term fixed-rate debt at what the company describes as a weighted average interest rate of 3.2% and a weighted average remaining term of 9 years.

The engine behind future rent growth is something Prologis calls lease mark-to-market. Most of the buildings are leased at rents that were agreed years ago, before market rents rose sharply. When those old leases expire and get renewed at today's rates, rent jumps significantly. For leases that rolled over in 2025, net effective rents increased by approximately 50%. The company estimates that the remaining gap between current in-place rents and today's market rates is still about 18%, meaning more rent increases are already baked into the portfolio even if market rents stop rising entirely.

What Is a Co-Investment Venture?
Prologis partners with large outside investors, like pension funds, to jointly own properties. Prologis manages the buildings and collects fees for doing so. This lets Prologis control far more real estate than it could own alone, without taking on all the financial risk itself. The fee income from these partnerships forms the Strategic Capital segment, which contributed $592 million in revenue in 2025.
The Strategic Capital segment adds a second layer of income on top of rent. Prologis manages $62.4 billion in properties held by its ten unconsolidated co-investment ventures. It earns recurring fees for asset management and property management, plus occasional bonus payments called promotes when the ventures hit performance targets. In 2024, promote revenue was $139 million. In 2025, it was just $2 million, which is one reason Strategic Capital segment profit fell from $380 million to $321 million between those two years. Promote income is lumpy and hard to predict, so the year-to-year swings in this segment can look dramatic even when the underlying fee business is growing steadily.

Prologis is also moving into a new category of real estate: data centers. The company argues its warehouse sites are already in locations with good power access and its land positions can be converted. At December 31, 2025, Prologis had $686 million of data center projects under development on an owned and managed basis. The company sold one completed data center in 2025 and generated gains from the transaction. This is a small part of the business today, but the company is directing more development activity toward it.

Data Center Development Begins
Prologis started converting select logistics sites into data centers, leveraging its land positions near power sources. The company had $686 million of data center total expected investment under development on an owned and managed basis at year-end 2025, with 60.9% of new consolidated development starts in 2025 being build-to-suit projects. This marks a deliberate push beyond traditional warehouse real estate into a new property type.
There are specific risks worth understanding. California properties generate 31.9% of operating income. A recession or tax law change in that one state could hit Prologis harder than a diversified landlord. Outside the US, the company holds $13.7 billion in foreign properties, with revenues in British pounds, euros, Canadian dollars, and Japanese yen. When those currencies weaken against the US dollar, reported income shrinks even if the buildings are performing well. The data center expansion introduces a different set of risks: securing reliable power supplies, navigating permit approvals, and managing construction costs that can run above initial estimates.

Customer concentration is moderate but real. The top 10 tenants account for 16.3% of rental income in the consolidated portfolio. Amazon alone represents 6.3%. If Amazon or another major tenant were to downsize its space, decline to renew leases, or run into financial trouble, the impact would be visible in the numbers. The co-investment structure adds another layer of dependency: Prologis manages $73.8 billion in assets for 159 outside investors. If partners wanted to pull capital at the same time, or disputed how properties should be run, the management fees and the assets behind them could shrink.
Occupancy across the total owned and managed portfolio sat at 95.8% at December 31, 2025, and has remained above 95% in both 2024 and 2025, suggesting demand for logistics space has stayed firm even as new supply entered some markets.
The Bet
Prologis depends on the idea that global demand for well-located warehouse and logistics space stays structurally strong, driven by e-commerce growth and companies rebuilding their supply chains closer to consumers. If that demand softens, market rents stop rising or fall, and the 18% rent mark-to-market embedded in the portfolio shrinks or disappears before those leases roll over. At the same time, the data center expansion assumes Prologis can secure reliable power, win build-to-suit contracts, and complete projects on budget in a capital-intensive category where it is not yet an established player. Both bets have to work together: the mature warehouse business has to keep funding the balance sheet while the newer data center business proves itself.
Open question
Net debt has grown from $17.2 billion in 2021 to $33.9 billion in 2025, even as the business has become more profitable. Prologis is adding a capital-heavy new business in data centers on top of an already leveraged balance sheet. The embedded rent mark-to-market of 18% provides a cushion, but market rents have shown negative growth in some recent quarters. If market rents continue to soften while construction costs and interest rates stay elevated, can the lease mark-to-market buffer and the data center bet generate enough new income to justify the rising debt load, or does the model depend on conditions that are already starting to shift?

Geographic Concentration
About 31.9% of the company's operating income comes from properties in California, particularly the Central Valley, San Francisco Bay Area, and Southern California. A major economic downturn in California, including changes to state income tax or property tax laws, could significantly hurt the company's overall financial performance.
Foreign Currency Risk
The company has $13.7 billion (13.8% of total assets) invested in properties outside the U.S., with revenues in foreign currencies making up 6.6% of operating income. If the value of foreign currencies like the British pound, Canadian dollar, euro, or Japanese yen drops significantly against the U.S. dollar, the company's reported financial results could be materially worse.
Real Estate Development
The company is developing new data center properties that require significant investment in power infrastructure and technology. If the company cannot secure reliable power supplies, obtain necessary permits from local governments, or if construction costs exceed estimates due to inflation or technical challenges, development projects could fail or become unprofitable.
Customer Concentration and Lease Renewal Risk
The top 10 customers represent 16.3% of the company's rental income. If these major customers stop paying rent, go bankrupt, or refuse to renew leases at favorable rates when they expire, the company's cash flow could drop significantly.
Co-Investment Venture Dependencies
The company manages $73.8 billion in properties through partnerships with other investors. If partners want to withdraw their money at the same time, dispute how properties should be operated, or if the company loses the right to manage these properties, the company could lose significant fee income and assets under management.
