• Reduction in loss on impairment of licenses by 65% to $47.7 million for the three months ended September 30, 2025, compared to $136.2 million in the prior year.
• Equity in earnings of unconsolidated entities increased by 62% to $69.8 million, primarily due to a $34.1 million gain on sale from Iowa entities' wireless operations to T-Mobile.
• Cash and cash equivalents increased by $181.9 million to $325.6 million as of September 30, 2025, from $143.7 million at December 31, 2024.

Negatives

• Net loss from discontinued operations attributable to Array shareholders was $(147.3) million for the three months ended September 30, 2025, due to the loss on sale of wireless operations.
• The company recorded an estimated purchase price true-up due to T-Mobile of $20.2 million as of September 30, 2025.

• Cost of operations increased by 15% to $21.0 million for the three months ended September 30, 2025, primarily due to increased cell site ground rent.
• Interest expense from continuing operations increased significantly to $(8.9) million for the three months ended September 30, 2025, from $(4.2) million in the prior year, due to a new term loan.
• The revolving credit agreement's maturity date was accelerated to April 2026 due to the T-Mobile sale.
• Echostar Communications (DISH Wireless) claims its obligations under its Master Lease Agreement are excused, potentially negatively impacting future site rental revenues, which were approximately $7 million for the full year 2025.
• Array recognized a $47.7 million impairment loss on retained high-band spectrum due to suppressed pricing and decreased demand, reflecting industry-wide challenges in operationalizing this spectrum.

Risks

• The remaining Array business (towers, non-controlling interests, spectrum licenses) is of a significantly smaller scale, potentially leading to operational, cost, and borrowing disadvantages.
• Uncertainty regarding which towers T-Mobile will permanently locate on, potentially leaving Array with towers without tenants and incurring significant decommissioning costs and remaining ground lease obligations.
• Array's business is substantially dependent upon T-Mobile, and failure by T-Mobile to meet its lease obligations would significantly impact Array's business and financial results.
• No guarantee that pending spectrum license sales to Verizon, AT&T, and T-Mobile will be consummated, with the ongoing government shutdown impacting closing timing.
• Inability to monetize remaining spectrum assets not subject to pending sales at mutually agreeable prices, coupled with ongoing costs to retain and comply with FCC build-out requirements for these assets.
• Increasing competition in the tower industry from public and private tower companies, utility towers, rooftops, and other structures, potentially leading to increased pressure on pricing, reduced tenancy rates, and lower profit margins.
• Economic and business risks associated with fixed-rate annual escalators on colocation revenue contracts, where ground lease escalations could exceed colocation revenue escalations, and sustained higher inflation could erode real revenues and margins.
• A substantial portion of Array revenues are derived from a small number of tenants (Verizon, AT&T, Echostar Communications, T-Mobile), making Array vulnerable to their loss or financial difficulties.
• Lower demand for wireless services, negative trends in the wireless industry, or changes in customer business models could decrease revenues from tenants.
• Inability to protect real estate rights with respect to land leases, potentially leading to non-renewal, unfavorable terms, or significant adverse effects on business.
• Adverse impact from extreme weather events, climate-related events, natural disasters, or other unforeseen events on towers, potentially interrupting service, causing damage, or incurring legal claims and costs.
• An inability to attract, develop, and retain outstanding talent, including key management personnel, which could adversely affect business and strategy execution.
• Costs, integration problems, or other factors associated with future acquisitions or divestitures of assets.
• Uncertainty in Array's or TDS' future cash flow and liquidity, level of indebtedness, or inability to access capital, deterioration in capital markets, changes in interest rates, or credit ratings could limit financing availability.
• Significant investments in wireless operating entities that Array does not control, with potential for losses in value or cash flows from such investments.
• Failure to timely or fully comply with existing or future legislative and/or regulatory requirements or changes thereto, including FCC, FAA, and other federal, state, and local regulations.
• Settlements, judgments, restraints on business, and/or costs from pending and future legal and policy proceedings.
• Potential conflicts of interest between TDS (controlling shareholder) and Array, as TDS controls 82.0% of Array and 96% of voting power.
• Provisions in Array's Restated Certificate of Incorporation and TDS's control may discourage or make a change in control more difficult.
• Cyber-attacks or other breaches of information technology security, including those intensified by AI technologies, could lead to data theft, operational disruptions, or inaccurate financial reporting.
• Disruption in credit or other financial markets, deterioration of U.S. or global economic conditions, or other events could impede access to financing or increase its cost, and result in reduced revenues and cash flows.

Future Outlook

Array expects legacy wireless operations winddown expenses to persist at third quarter 2025 levels into the first half of 2026, with some expenses remaining after that time but declining in the second half of 2026. The company anticipates declaring additional special dividends upon the closure of pending spectrum license sales to AT&T and Verizon, and may declare regular cash dividends thereafter. Array continues its strategic alternatives review process to opportunistically monetize its remaining spectrum assets. The timing of regulatory approval for spectrum transactions may be impacted by the duration of any U.S. federal government shutdown.

Management Comments

• Array connects America through digital infrastructure by leasing tower space to tenants and providing ancillary services.
• Array seeks to grow tower revenue primarily through increasing colocations on existing towers and amendments to existing colocations.
• Array expects T-Mobile to cancel the interim leases prior to the full 30-month duration, and expects revenue to decline correspondingly.
• Array expects its pending sales of spectrum licenses to AT&T and Verizon, which are subject to regulatory approvals and customary closing conditions, to deliver substantial proceeds and expects its Board of Directors to declare special dividends upon closure of these transactions.
• Array expects its Board of Directors to declare special dividends upon closure of these transactions. The Array Board of Directors may declare regular cash dividends after the close of these transactions.
• Array believes that existing cash and investment balances, distributions from unconsolidated entities, expected cash flows from operating activities, expected and potential dispositions of licensed spectrum assets and funds available under its financing agreements will provide sufficient liquidity for Array to meet its day-to-day operating needs and debt service requirements.
• Array believes that it was in compliance as of September 30, 2025 with all such financial covenants.
• Array believes that the Relators claims are without merit and that Advantages and King Streets participation in FCC auctions complied with applicable law and FCC Rules.
• Array is unable at this time to determine whether the outcome of these actions would have a material impact on its results of operations, financial condition, or cash flows. Array intends to contest plaintiffs' claims vigorously on the merits.

Industry Context

Array's transformation into a pure-play digital infrastructure company, following the divestiture of its wireless operations to T-Mobile, aligns with a broader industry trend of telecom companies divesting non-core assets to focus on infrastructure or service provision. The company's emphasis on tower leasing and spectrum monetization positions it within the growing digital infrastructure sector, which benefits from increasing demand for data and 5G deployment. However, the industry faces challenges such as intense competition among tower companies, potential consolidation among wireless carriers reducing demand for new tower sites, and the complexities of monetizing high-band spectrum due to operationalization difficulties. The ongoing legal dispute with DISH Wireless highlights the contractual risks inherent in relying on a few large tenants in a dynamic wireless market. The company's strategic shift aims to capitalize on the stable, recurring revenue streams characteristic of the tower industry, while navigating the evolving landscape of spectrum utilization and carrier demands.

Comparison to Industry Standards

• Array's tower tenancy rate of 1.02 is relatively low compared to established tower companies like American Tower (AMT) or Crown Castle (CCI), which typically have tenancy rates closer to 2.0 or higher, indicating significant room for colocation growth or a smaller average number of tenants per tower.
• The strategic shift to a pure-play tower company, similar to the business models of American Tower and Crown Castle, positions Array to benefit from recurring revenue streams, but its smaller scale (4,449 towers) compared to these industry giants (e.g., AMT with over 220,000 sites globally, CCI with over 40,000 towers in the US) suggests it may face challenges in achieving similar economies of scale and market leverage.
• The impairment loss on high-band spectrum due to "suppressed pricing and decrease in demand" and "industry-wide challenges encountered related to the operationalization of this spectrum" reflects a broader industry issue, as many carriers and infrastructure providers are grappling with the technical and economic viability of deploying high-band (mmWave) spectrum for widespread use, a challenge also faced by companies like Verizon and AT&T in their 5G deployments.
• The T-Mobile Master License Agreement (MLA) for 2,015 new towers and 600 existing towers for a 15-year term provides a stable, long-term revenue base, comparable to the long-term contracts that underpin the business models of major tower operators, ensuring predictable cash flows.
• The special dividend of $23.00 per share, totaling $1,986.7 million, is a significant return of capital to shareholders, a common practice for companies undergoing major asset sales, similar to how other telecom companies have distributed proceeds from large divestitures.

Corporate Governance

Legal Proceedings

• **DOJ False Claims Act Inquiry (Advantage Spectrum, King Street Wireless)**: The U.S. Court of Appeals for the D.C. Circuit affirmed the dismissal of the case involving King Street in April 2025, but plaintiffs filed a petition for certiorari with the U.S. Supreme Court on September 5, 2025. The D.C. Circuit reversed the dismissal of the case involving Advantage Spectrum on September 26, 2025, remanding it for further proceedings. Array believes the claims are without merit and intends to contest vigorously.
• **Stockholder Class Action (TDS and Array)**: A putative stockholder class action alleging violations of the Securities Exchange Act of 1934 was settled in principle on February 28, 2025, and the court approved the settlement and dismissed the lawsuit with prejudice on September 4, 2025.
• **Stockholder Derivative Lawsuit (TDS and Array directors/officers)**: A derivative lawsuit alleging breach of fiduciary duty was filed on January 31, 2025. A motion to dismiss was filed on July 23, 2025, and a status conference on this motion is set for January 23, 2026. Array is unable to determine the material impact but intends to contest vigorously.

Related Party Transactions

• Array is an 82.0%-owned subsidiary of Telephone and Data Systems, Inc. (TDS), which controls 96% of Array's combined voting power.
• TDS and Array have entered into contractual arrangements governing certain transactions and relationships, some of which were not the result of arms-length negotiations.
• Six of Array's nine directors are also directors and/or executive officers of TDS and/or Array, creating potential conflicts of interest.
• The Tax Allocation Agreement provides that Array remits income tax payments to TDS consistent with when such payments would be paid if Array and its subsidiaries were a separate affiliated group.
• Following the close of the T-Mobile transaction, TDS entered into a transition services agreement (TSA) with T-Mobile to provide ongoing services and support, which does not materially impact Array's consolidated financial statements.

Stakeholder Impact

• **Shareholders**: Received a significant special dividend of $23.00 per share. Expected to receive further special dividends from pending spectrum sales. The strategic shift to a pure-play tower company aims to provide more stable, recurring revenue streams. However, the ongoing control by TDS and potential conflicts of interest could impact minority shareholder interests.
• **Employees**: Reduction in headcount related to the sale of wireless operations, leading to decreased accrued compensation. Winddown costs for legacy wireless operations are expected to continue.
• **Customers (Tenants)**: T-Mobile has entered into a Master License Agreement for new and existing tower leases, ensuring continued service. However, the dispute with DISH Wireless could impact their service or contractual obligations.
• **Creditors**: Significant debt repayments and exchanges have occurred, improving the company's debt profile and leading to improved credit ratings. A new term loan was secured. The company believes it is in compliance with all financial covenants.
• **Suppliers**: Changes in operations and potential decommissioning of towers could impact relationships with ground lessors and other service providers.

Next Steps

• Close pending spectrum license sales to Verizon, AT&T, and T-Mobile.
• Opportunistically monetize remaining spectrum assets not subject to executed agreements.
• Manage legacy wireless operations winddown expenses, which are expected to persist into the first half of 2026 and decline in the second half of 2026.
• Potentially declare additional special dividends upon closure of AT&T and Verizon spectrum transactions.
• Potentially declare regular cash dividends after the close of major spectrum transactions.
• Continue to contest the stockholder derivative lawsuit, with a status conference set for January 23, 2026.
• Address the D.C. Circuit's reversal and remand of the Advantage Spectrum case for further proceedings.
• Respond to the U.S. Supreme Court's request regarding the King Street case.

Key Dates

Recommendation

Array Digital Infrastructure has undergone a significant strategic transformation, divesting its wireless operations and focusing on its digital infrastructure business. The Q3 2025 results show a substantial improvement in continuing operations' profitability and liquidity, driven by the T-Mobile tower lease agreement and proceeds from the divestiture. The company has also returned significant capital to shareholders via a special dividend and improved its credit profile. However, the stock's future performance is heavily reliant on the successful closure of pending spectrum sales, which face regulatory and government shutdown risks. The ongoing legal dispute with DISH Wireless and the inherent risks of being highly dependent on a few major tenants introduce uncertainty. While the long-term outlook for digital infrastructure is positive, the current transition phase, coupled with the need to fully monetize remaining spectrum and resolve legal matters, suggests a 'hold' recommendation. Investors should monitor the progress of spectrum sales and the resolution of legal and operational wind-down costs before considering a stronger position.
