Array Digital: The Tower Business Is Accelerating. Wall Street's Stuck on Corporate Drama.

Array Digital's stock is down roughly 80% over the past year. Over that same period, site rental revenue — the core tower leasing business — grew 95% year over year in the second quarter, the tenancy rate climbed to 0.98, and management raised every element of full-year guidance.

The disconnect between the price action and the operating momentum is the thesis. The market is fixated on a stalled buyout proposal from parent TDS and the winding down of spectrum sales, treating both as existential threats. They're not. The tower business itself is growing into its own valuation, and the math doesn't require TDS to close a deal to justify it.

The tower operations are the story, not the spectrum

Q2 operating revenue of $54.1 million was up 90% from $28.5 million a year ago. Nearly all of that growth came from site rental revenue — $53.2 million, up 95%. Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization, a proxy for cash earnings from core operations) rose 56% to $56.2 million. Adjusted OIBDA (operating income before depreciation and amortization) flipped from a $9.5 million loss to a $15.1 million profit.

The GAAP headline — $358.7 million in net income, $4.15 per share — is dominated by one-time spectrum license sales worth $1.16 billion in proceeds. Those gains won't repeat. The question isn't whether GAAP earnings normalize. The question is whether the underlying tower cash engine justifies the current enterprise value on its own.

Management raised guidance on every metric

After Q2, management lifted the full-year outlook across the board:

• Operating revenue: $205M–$215M (low end up $5M)
• Adjusted EBITDA: $220M–$235M (both ends up $20M)
• Adjusted OIBDA: $60M–$75M (both ends up $10M)

Raising guidance when the spectrum wind-down is in full view is a meaningful signal. It means the tower business is outpacing the spectrum fade. Capital expenditures are held at $25M–$35M — minimal capex for an infrastructure company with 4,456 owned towers and 4,362 colocations.

The tenancy rate tells the real story

The tenancy rate — the ratio of tenants per tower — moved from 0.96 in Q1 to 0.98 in Q2, with colocations climbing 72 sequentially. T-Mobile's committed minimum of 2,015 sites is locked in. The DISH Wireless bankruptcy removed revenue uncertainty that was already being recognized as unlikely, so that cloud cleared rather than deepened.

A tenancy rate approaching 1.0 on 4,456 towers means nearly every site has more than one carrier tenant. That's the structural lever in the tower model: fixed infrastructure costs spread across multiple revenue streams.

The TDS buyout is a separate equation

TDS, which controls about 81.9% of Array shares, submitted a non-binding proposal in May to acquire the remaining public shares at 0.86 TDS shares per Array share. An independent special committee is evaluating it. No decision has been made.

At today's prices, TDS trades at roughly $33.63, which puts the proposed bid value at about $28.92 per Array share. Array currently trades at $36.07 — above the proposed bid. Minority shareholders are already pricing in either a higher offer or standalone value. That's a point in favor of the underlying business, not a reason to wait for corporate action.

If the deal goes through at or near those terms, the market would need to accept a significant haircut. If it doesn't, the stock's upside is tied to the tower business compounding into a multiple that reflects its actual growth trajectory. Either way, the operating metrics are the real anchor.

EV/EBITDA closes the argument

Array's enterprise value sits at approximately $3.54 billion. Using the midpoint of raised adjusted EBITDA guidance — $227.5 million — the stock trades at roughly 15.6x EV/EBITDA.

American Tower, the largest pure-play tower REIT, trades at 16.6x EV/EBITDA. Crown Castle is at 18.6x. Array is cheaper than both, on raised guidance with a tenancy rate pushing toward 1.0 and 95% year-over-year site rental growth.

AInvest's aggregate signal labels the stock a Hold, with a composite analysis score of 2.41 and a fundamental rating of 6.08. The conservative rating reflects the spectrum normalization and governance overhang — legitimate concerns, but they don't erase the peer discount on a business that's accelerating.

What breaks the setup

If the TDS special committee delivers a final offer at or below current TDS-implied value and the market accepts it as a ceiling, the stock could be capped at roughly $29. TDS itself has struggled with debt and execution problems at its 3G Wireless subsidiary, so the exchange ratio carries counterparty risk. If tower growth stalls — if carriers pause 5G densification or if the remaining $30 million in pending spectrum deals don't close — the guidance raise unravels.

The bottom line

Array Digital is trading below the EV/EBITDA multiple of slower-growing tower peers while raising guidance on a tower business that grew site rental revenue 95% year over year. The spectrum wind-down is a known, finite event. The TDS committee drama is a governance question, not a business model question. At roughly 15.6x raised adjusted EBITDA guidance, the stock doesn't price in the acceleration already happening on its own towers.
