Array (AD) Q4 2025 earnings review
A Pure-Play Tower Pivot Powered by T-Mobile
Reversing its historical trajectory as a capital-intensive regional wireless carrier, Array has successfully transformed into a highly profitable, pure-play tower company. Q4 represents the first full quarter of this new era, driven by the T-Mobile Master Lease Agreement (MLA). The results are stark: site rental revenues are accelerating, up 51% YoY to $55.0M. Net income from continuing operations reversed a year-ago loss, landing at a positive $41.4M. While the DISH non-payment dispute and legacy wind-down costs create near-term noise, the core leasing engine is running smoothly and throwing off substantial cash.
🐂 Bull Case
The 15-year T-Mobile MLA is already delivering. Array processed over 2,000 applications and completed structural analyses on 95%+ of them in Q4, clearing the path for high-margin, long-term recurring revenue.
Array successfully closed the $1.0B AT&T spectrum sale in January 2026, triggering a $10.25 special dividend. With Verizon pending and C-Band assets still retained, the company holds a massive, unencumbered piggy bank.
🐻 Bear Case
DISH has halted its master lease payments, claiming FCC actions relieve its obligations. This removes roughly $7M in high-margin annual revenue and introduces unneeded legal friction into the new standalone model.
Once T-Mobile finalizes its 2,015 committed sites by 2028, Array will be left with 800 to 1,800 'naked' towers carrying zero tenants. The holding and eventual decommissioning costs for these dead assets will drag on future cash flows.
⚖️ Verdict: 🟢
Bullish. The successful divestiture of the wireless business unlocked immense value. The tower unit is instantly profitable, and the retained spectrum provides a multi-billion dollar safety net. If management can control wind-down costs and win the DISH dispute, the floor is very high.
Key Themes
Core Colocation Engine is Accelerating
Even excluding the massive T-Mobile MLA and the DISH revenue drag, same-store site rental growth is accelerating at a healthy 6% YoY. Management explicitly credited roaming replacement builds (carriers replacing former UScellular roaming coverage with their own sites) and the newly insourced sales team for driving a 47% increase in non-T-Mobile colocation applications.
DISH Network Non-Payment Contradicts Clean Slate
Despite the positive narrative of predictable, locked-in tower cash flows, DISH's sudden halt of contractual payments in December introduces a sharp negative break in trend. Array recognized $7M from DISH in 2025 and was owed similar levels through 2031. Management was forced to completely strip DISH from its 2026 guidance, highlighting the vulnerability of concentrated tower tenant risk.
Macro Data Demand Sustains Leasing Pipeline
Management continues to cite relentless macro mobile data demand and 5G deployment as the primary drivers protecting the value of their rural/suburban-heavy tower portfolio. Because 33% of Array's towers have no competing site within a two-mile radius, carriers expanding their 5G footprints have little leverage to bypass Array's infrastructure.
Stubborn Transition Costs Dilute Margins
While revenues surged 51%, total operating expenses remained stubbornly high at $51.7M in Q4. Selling, general, and administrative (SG&A) expenses stood at $15.3M. Management admitted these elevated costs are necessary to support the wind-down of the legacy wireless operations and expects them to persist through 2026, delaying the realization of true pure-play tower margins.
Infrastructure Innovation: Tower Light Monitoring
As part of its modernization to a standalone tower operator, Array is migrating its tower light monitoring to a new long-term technological solution. This specific infrastructure upgrade requires a $6M capital expenditure in 2026 but is vital for automating compliance and reducing future operational truck rolls.
Other KPIs
Accelerating. Following the August sale of the wireless division, Array modified its AFCF calculation to better reflect a standalone tower company. Q4's $74.9M AFCF easily covered ongoing maintenance CapEx ($2.0M) and highlights the sheer cash-generation capability of the asset-light tower model.
Decelerating. Down 31% YoY from $37.9M in 24Q4. This decline is largely due to one-time factors affecting the AT&T and Verizon managed wireless partnerships in the prior year. Despite the drop, these passive investments remain a lucrative, low-effort cash machine for the company.
Guidance
Accelerating. The midpoint of $207.5M implies a 27% YoY increase over FY25's $163.0M. This growth is driven by a full year of the T-Mobile MLA and strong organic colocation demand, despite management conservatively stripping out all assumed DISH revenues from the forecast.
Stable. The midpoint of $207.5M implies a 7% YoY increase over FY25's $194M. The margin expansion is partially constrained by the persistence of legacy wireless wind-down costs (elevated SG&A) that will last throughout 2026.
Reversing. The midpoint of $57.5M represents a massive leap from FY25's marginal $1.0M. This metric strips out passive equity earnings and interest income, revealing the true underlying profitability shift of the core tower operating activities post-transaction.
Stable. In line with FY25's $30M. This includes $6M for the tower light monitoring migration and incorporates a degree of uncertainty regarding how many underlying ground leases Array will attempt to purchase outright to optimize its cost structure.
Key Questions
DISH Legal Strategy
Given DISH's sudden halt of master lease payments, what specific legal recourses is Array pursuing, and at what point does management consider evicting DISH equipment to make room for paying tenants?
The Naked Tower Equation
With potentially up to 1,800 'naked' towers remaining after T-Mobile's final selections, what is the exact crossover math between the cost of holding a dead tower to market it versus the raw cost of decommissioning it?
C-Band Monetization Timeline
With the AT&T deal closed and Verizon pending, Array still holds highly valuable C-Band spectrum. Without build-out requirements until 2029, what market signals or price thresholds are you waiting for before pulling the trigger on a final spectrum sale?
