What Prologis, Inc. told the SEC could break it.
For Prologis, the dominant thread is geographic: California alone held 30.6% of its operating properties ($24.7 billion) and generated 31.9% of its consolidated operating-property net operating income at the end of 2025, so a downturn in that one state's economy, real-estate market or tax law would weigh heavily — and that same concentration overlaps with physical risk, since California, along with Washington, Japan and Mexico, sits in known earthquake zones. As a global logistics REIT it is also exposed to tariffs and trade wars that can dent demand for warehouse space, and because REIT rules require it to distribute most of its income, it leans on outside capital even in unfavorable markets. Its tenant base, by contrast, is comparatively spread out — its top 10 customers were 16.3% of net effective rent.
4 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Geographic concentration
- California = 30.6% of operating properties ($24.7B), 31.9% of consolidated operating-property NOIhigh
At year-end 2025, 30.6% of Prologis' consolidated operating properties ($24.7B gross book value, 23.6% of square footage) were in California, generating 31.9% of consolidated operating-property NOI; a downturn in California's economy, real-estate conditions or tax laws could materially affect its business.
“30.6% of our consolidated operating properties or $24.7 billion (based on consolidated gross book value, or investment before depreciation) were located in California (Central Valley, San Francisco Bay Area and Southern California markets), which represented 23.6% of the aggregate square footage of our operating properties and 31.9% of our consolidated operating property NOI.”

Climate & physical
- earthquake exposure — properties in California, Washington, Japan, Mexico seismic zonesmedium
A number of Prologis' wholly owned and venture-owned investments are in known earthquake-activity areas — U.S. markets in California and Washington and international markets in Japan and Mexico; it carries earthquake insurance and sponsored a catastrophe bond (through 2027) but losses or higher insurance costs could hurt results.
“A number of our investments, both wholly owned and owned through co-investment ventures, are located in areas that are known to be subject to earthquake activity. U.S. properties located in active seismic areas include properties in our markets in California and Washington. International properties located in active seismic areas include Japan and Mexico.”

Regulatory & policy
- tariff/trade-war policy affecting logistics demand; REIT distribution/capital-access dependencemedium
As a global logistics REIT, Prologis is exposed to taxes, tariffs and trade wars (it cited economic disruption from April 2025 tariff-policy proposals affecting demand); to keep REIT status it must distribute most income and may need third-party capital or short-term borrowing to fund needs even in unfavorable markets.
“we are subject to various regulatory requirements, tax and other laws as well as exposed to economic and geopolitical matters such as taxes, tariffs, trade wars and laws within the countries in which we operate and unexpected changes in these items may result in unanticipated losses”
Customer concentration
- top-10 customers = 16.3% of consolidated NER / 15.2% of O&M NER (no single >10%)low
Prologis' top-10 customers accounted for 16.3% of consolidated net effective rent and 15.2% of owned-and-managed NER at year-end 2025; default by a significant number of customers would adversely affect operating results and distributable cash flow.
“At December 31, 2025, our top 10 customers accounted for 16.3% of our consolidated NER and 15.2% of our O&M NER.”
