In its own words
What could break it.
Customer concentration
- Array tower-tenant concentration in three carriers (T-Mobile cancellation risk)medium
After divesting UScellular's wireless operations, TDS's Array tower business depends on a handful of large carrier tenants — T-Mobile, AT&T and Verizon — for most lease revenue; T-Mobile can cancel interim leases tower-by-tower at will and Array expects it to cancel before the 30-month term, so revenue is expected to decline correspondingly, underscoring concentration and churn risk among a few tenants.
“Array's largest tenants include T-Mobile, AT&T and Verizon.”
