What United Parcel Service, Inc. told the SEC could break it.
UPS's disclosures are shaped by a deliberate retreat from its largest customer and the labor and trade forces around its network. Amazon was 10.6% of 2025 revenue, but UPS is intentionally cutting that volume more than 50% by June 2026 and shrinking facilities, vehicles, aircraft, and headcount to match — so the risk is execution and stranded costs rather than dependence. At the same time nearly 80% of its U.S. employees are unionized, primarily Teamsters, making strikes or slowdowns a material threat, while 2025 trade-policy changes — tariffs and de-minimis exclusions — reduced its China-to-U.S. lane volumes and pressured international margins, with foreign-currency swings adding further exposure.
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.
Other disclosures
- unionized workforce — ~80% of U.S. employees in unions; strike/work-stoppage/slowdown riskmedium
UPS has ~460,000 employees (370,000 U.S.), of whom nearly 80% of U.S. employees are represented by unions (primarily Teamsters handling/transporting packages); strikes, work stoppages or slowdowns by its employees could materially adversely affect the business.
“Nearly 80% of our U.S. employees are represented by unions, primarily those employees handling or transporting packages.”
SEC filing →As of 2026 - foreign-currency exposure — ~$647M fair-value sensitivity on currency derivatives to a 10% USD movelow
UPS's international operations expose it to FX risk; a hypothetical 10% weakening of the U.S. dollar implied a ~$647 million change in the fair value of its currency derivatives at year-end 2025 (offset by changes in the underlying hedged transactions), and currency movements materially affect international revenue per piece.
“Change in Fair Value: Currency Derivatives (1) $ (647) $ (749)”

Customer concentration
- Amazon = 10.6% of revenue / 13.6% of AR; deliberate >50% volume reduction by June 2026 + stranded-cost execution riskmedium
Amazon was UPS's largest customer at 10.6% of 2025 consolidated revenue (11.8% in 2024) and 13.6% of net accounts receivable; UPS is deliberately reducing Amazon volume >50% by June 2026 (vs 2024) and cutting facilities/vehicles/aircraft/workforce — if it cannot make appropriate adjustments or control stranded costs, profitability could be materially impacted.
“Our strategy includes planned volume declines from our largest customer, Amazon.com, Inc. For 2025, this customer and its affiliates accounted for 10.6% of our consolidated revenues. In connection with the execution of this strategy, we have made and continue to make reductions in the number of our facilities, vehicles and aircraft, and our workforce”

Regulatory & policy
- trade-policy/tariffs/de-minimis exclusions — China-to-U.S. lane volume/margin pressure (Q2 2025)medium
Global trade-policy changes during 2025 — including pending/enacted tariffs and de-minimis exclusions that took effect in Q2 2025 — shifted trade-lane volumes, particularly reducing UPS's China-to-U.S. lane volumes and pressuring International Package segment margins and Forwarding revenue.
“Global trade policy changes during 2025, including pending and enacted tariffs and de minimis exclusions, resulted in shifting trade lane volumes, particularly reducing volumes on our China to U.S. lane, pressuring our International Package segment margins during the year.”

Its customers
“In 2025, one customer, Amazon.com, Inc. and its affiliates, represented approximately 10.6% of our consolidated revenues, substantially all of which was within our U.S. Domestic Package segment. As previously disclosed, our strategy involves reducing volumes from this customer by more than 50% by June 2026 from 2024 levels.”
