Erosion risks

• Amazon Logistics and regional carriers expanding last-mile density
• USPS expanding last-mile partnerships and offerings
• Volume declines reduce network utilization and density advantages

Leading indicators

• U.S. average daily volume and stop density
• On-time performance metrics
• Cost per piece / margin trend in U.S. Domestic

Counterarguments

• Shippers increasingly multi-source across UPS/FedEx/USPS/Amazon and regional carriers
• E-commerce networks (notably Amazon) are building comparable last-mile density in key metros

Erosion risks

• Loss of large-customer volume reduces fixed-cost absorption
• Higher labor costs can offset scale benefits
• Automation capex may not yield expected cost reductions

Leading indicators

• Average daily volume and revenue per piece
• Network utilization and sort capacity metrics
• Mix shift toward lower-yield products (e.g., economy/returns)

Counterarguments

• Large customers can insource or rebid volumes, limiting long-term scale advantages
• USPS and alternative carriers can underprice on low-value residential deliveries

Erosion risks

• Competitive pricing pressure in B2C and economy products
• Large-customer contract repricing lowers net yields

Leading indicators

• Average revenue per piece and yield
• Discount rate trends and accessorial revenue
• Churn among top 25 customers

Counterarguments

• Rate increases are often matched by peers and offset by higher discounts
• E-commerce shippers can shift volume to the cheapest service that meets SLA

Erosion risks

• Multi-carrier shipping software reduces integration lock-in
• E-commerce platforms increase carrier choice and price transparency

Leading indicators

• Digital Access Program adoption / volume attributed to DAP
• Customer churn and net revenue retention in SMB
• Share of shipments purchased via partner platforms

Counterarguments

• Most shippers can switch carriers within shipping software; integrations are often standardized
• Carriers compete heavily on price and surcharges even with integrations in place

Erosion risks

• Service disruptions can quickly damage brand perception
• Price competition encourages customers to trade down to cheaper alternatives

Leading indicators

• On-time performance vs peers
• Claims/damage rates and customer complaints (where disclosed)
• Customer concentration and contract renewals

Counterarguments

• For many shippers, carrier choice is primarily price-driven and multi-sourced
• Amazon and USPS can be acceptable substitutes for slower/low-value shipments

Erosion risks

• Trade policy, tariffs, and customs/regulatory changes
• Macro downturn reduces premium international volumes
• Competitive intensity from DHL and other integrators

Leading indicators

• International export volume growth by lane
• International average revenue per piece
• On-time performance on key lanes

Counterarguments

• DHL has comparable or stronger network density in parts of Europe and other regions
• Postal operators and regional integrators can undercut on deferred services

Erosion risks

• Technology advantages diffuse as competitors adopt similar tools
• Operational disruptions (weather, labor, geopolitical events)

Leading indicators

• Service quality metrics (late deliveries, claims)
• Unit cost and margin trend in International Package
• Revenue per piece and lane mix (especially China-to-U.S. and EMEA)

Counterarguments

• Technology is increasingly commoditized across major carriers
• Cross-border service is vulnerable to exogenous disruptions outside carrier control

Erosion risks

• SMBs use multi-carrier platforms that abstract away carrier choice
• Marketplace shipping programs steer volume based on price

Leading indicators

• SMB export volume growth
• Share of label purchases via partner platforms

Counterarguments

• International shipping labels are easy to compare and switch among carriers
• Many exporters use freight forwarders that choose carriers on their behalf

Erosion risks

• Customers unbundle to best-of-breed forwarders/3PLs
• Freight forwarding is price-competitive and cyclical
• Execution complexity across multiple service lines

Leading indicators

• SCS operating margin trend
• Growth in healthcare logistics and specialized offerings
• Cross-sell attach rates (parcel + logistics) where disclosed

Counterarguments

• Asset-light forwarders and pure-play 3PLs can match service breadth via partners
• Many customers select providers via competitive tenders with frequent rebids

Erosion risks

• Warehouse and fulfillment space is replicable (capex + leases)
• Digital returns and same-day services face new entrants

Leading indicators

• Capacity utilization in logistics facilities
• Returns volume growth and processing times
• Customer concentration in key verticals (e.g., healthcare)

Counterarguments

• Contract logistics is crowded; customers can switch providers at renewal
• Large retailers can build in-house fulfillment and returns networks

Erosion risks

• Returns and last-mile platforms are easy to multi-home
• Competitive marketplaces can route demand to lowest-cost providers

Leading indicators

• Happy Returns adoption (merchant count/volume) where disclosed
• UPS Store access-point footprint changes
• Attach rate of UPS Capital insurance

Counterarguments

• Returns and same-day delivery often have low contractual lock-in
• Alternative platforms can integrate with the same e-commerce front ends
