Summary

  • The T-Mobile purchase of UScellular's wireless operations closed on 1 August 2025 on $4.3 billion of total consideration after adjustments, made up of $2.6 billion in cash and about $1.7 billion of assumed debt, and the seller was renamed Array Digital Infrastructure, Inc.
  • Cash conversion is executed rather than merely announced, in two stages: a $23.00 per-share special dividend paid on 19 August 2025, and the $1.018 billion AT&T spectrum sale that closed on 13 January 2026, followed by a $10.25 per-share special dividend paid on 2 February 2026.
  • The retained rent book runs on two clocks: a minimum of 2,015 towers on 15-year terms plus roughly 600 extended colocations, against about 1,800 towers leased on 30-month interim terms that T-Mobile may cancel tower by tower.
  • Still unexecuted: the roughly $1,000 million Verizon licence sale, about $178 million of further spectrum agreements, and the final purchase-price adjustment due roughly 180 days after the closing.
  • Control sits with Telephone and Data Systems, which held 82.0% of Array's equity at 30 September 2025, so the order in which dividends, debt repayment and buybacks occur also determines who receives the cash.

On 1 August 2025 the divestiture of United States Cellular Corporation's wireless operations and select spectrum assets to T-Mobile US closed, and the seller emerged under a new name: Array Digital Infrastructure, Inc. (closing disclosure). Total consideration received at closing was $4.3 billion after adjustments, comprising $2.6 billion in cash proceeds and approximately $1.7 billion of debt assumed by T-Mobile through an exchange offer made to UScellular's debtholders, which the parties expected to settle on 5 August 2025. The same disclosure carried the caveat that governs every figure in this article: consideration remained subject to final adjustment approximately 180 days after the closing date.

The structure had been announced far earlier and at a slightly larger nominal size. The 24 May 2024 agreement between Telephone and Data Systems, UScellular and T-Mobile provided for $4,400 million payable in a combination of cash and the assumption of up to approximately $2 billion of debt, subject to adjustments (pro forma disclosure). Four hundred million dollars of that price was tied to the transfer of certain spectrum licences owned by King Street Wireless and Advantage Spectrum, contingent on designated-entity buyouts that the pro forma record shows were completed before closing. The distance between $4,400 million as announced and $4.3 billion as received is the arithmetic of those adjustments, not a renegotiation. The retrieved record does not establish the settled figure after the 180-day window, which is the first genuine gap in the ledger.

The closing-day accession also carries the transaction exhibit filed with the disclosure (exhibit filing), and the company's periodic reporting continues to be filed under its long-standing registrant identity, with the quarterly and annual reports listed on its (EDGAR filing index). That continuity matters: the renamed company is the same registrant, with the same reporting obligations and the same controlling shareholder, not a new entity with a clean history.

What the residual company actually kept

What Array retained is the substance of the story. The closing disclosure describes approximately 4,400 owned towers, noncontrolling investment interests, and spectrum holdings across various bands, and describes the tower assets as representing the fifth largest tower business in the United States. That is a specific claim of scale, and it frames the central question: a company with under $200 million of annual continuing-operations revenue is a tower landlord with a spectrum inventory, not a carrier.

The rent attached to those towers was restructured at the same moment. T-Mobile entered a 15-year Master License Agreement to be a long-term tenant on a minimum of 2,015 incremental Array towers and to extend the lease term for approximately 600 towers where T-Mobile was already a tenant. A separate 12-month Spectrum Manager Lease Agreement relating to retained Array spectrum was entered at closing, with pro forma incremental income of $150 million for the year ended 31 December 2024.

That $150 million figure is a pro forma estimate attached to a one-year arrangement, not an audited result, and it should be read as the shape of the intended income rather than as income achieved.

The remainder of the tower book is weaker by construction. T-Mobile leases space on approximately 1,800 Array-owned towers on an interim basis, for an interim term of 30 months, and may cancel tower by tower at any time. Revenue from those interim leases in the third quarter of 2025 — covering two months from the 1 August 2025 commencement — was $5.4 million. The asymmetry is the point: the long-dated commitment covers a defined minimum of towers, while a comparable number sit on short, unilaterally cancellable terms. Array carries the renewal risk on that second block; T-Mobile carries optionality.

How much of the interim block converts to durable rent is not established by any document in the record.

The cash-conversion chain, in order

The sequence from closed sale to shareholder cash is documented and dated. On the closing date the Array board declared a special dividend of $23.00 per Common and Series A Common Share for holders of record on 11 August 2025, paid on 19 August 2025. Because the distribution exceeded 25% of the prevailing share price, the exchange determined that the shares traded with due bills through and including the payment date, with the ex-dividend date set at 20 August 2025 (special dividend notice). That is a mechanical detail with a practical consequence: a dividend of that size is treated by the market as a return of capital event, and it is priced accordingly.

The nine-month cash flow statement for the period ended 30 September 2025 shows the other side of the same chain. Cash used in financing activities from continuing operations was $2,662.2 million, primarily $1,986.7 million of dividends paid to Array shareholders and $875.3 million of long-term debt repayments, partly offset by $325.0 million borrowed under the CoBank term loan (quarterly filing). Read together, those two lines say something simple and worth stating plainly: most of the cash that arrived was distributed, a substantial second slice repaid debt, and a smaller amount was borrowed to support the position.

The debt restructuring behind the closing is set out in the TDS quarterly filing summary. The exchange closed on 5 August 2025 and exchanged $1,680.1 million of long-term debt; Array retained $363.9 million of senior notes, made up of $55.1 million at 6.7%, $105.8 million at 6.25%, and pairs of 5.5% notes due in 2070. Array borrowed $325.0 million under a CoBank term loan maturing in June 2030 at SOFR plus 2.50%, repaid $713.3 million of unsecured term loan borrowings in August 2025, and its parent TDS repaid $781.3 million of its own unsecured term loans (filing summary). These figures are drawn from a secondary summary of the parent's Form 10-Q rather than from the filing text as read directly, and they should be attributed accordingly.

The AT&T close, and what it funded

On 13 January 2026 Array and certain subsidiaries completed the sale of select spectrum assets to New Cingular Wireless PCS, LLC (AT&T) under a licence purchase agreement dated 6 November 2024. The purchase price received at closing was $1.018 billion, paid in cash, with no portion deferred; $232 million of that price was allocated to certain 700 MHz designated-entity spectrum licences held by entities in which Array now holds 100% of the equity interests (completion filing). The absence of deferral is the material detail. A seller that receives cash with nothing held back has converted the asset; a seller carrying seller notes has not.

The company's own announcement framed the transaction as furthering the objective announced on 28 May 2024 of opportunistically monetising the spectrum not included in the sale to T-Mobile, and noted that the Array board declared a special cash dividend of $10.25 per Common and Series A Common Share following the close, payable on 2 February 2026 to holders of record on 23 January 2026 (company announcement). The pattern is now visible twice: an asset closes, cash arrives, and a special dividend follows on the same date as the declaration. Whether that pattern is capital discipline or balance-sheet attrition is the manuscript's central question, and the record supports both readings.

Array's management has continued to present tower operations as a strategic subject in its public appearances, including a conference appearance on strategic moves in tower operations (conference coverage). That presentation is a claim by the company, not evidence of durable rent.

What has not closed

Against two executed deliveries stands one large pending one. Array expects its pending sale of spectrum licences to Verizon, subject to regulatory approval and customary closing conditions, to deliver substantial proceeds, and expects its board to declare a special dividend upon closing; the maximum number of shares that may yet be purchased under its repurchase programme was 658,107 as of 31 December 2025, and the company did not determine to terminate that programme during the fourth quarter (annual report disclosure). The Verizon agreement itself dates from 17 October 2024 and covers certain AWS, Cellular and PCS licences for total proceeds of $1,000 million, subject to regulatory approval. No closing date is established in the record, and the contracted amount remains subject to adjustment.

The smaller pieces matter less but point the same way. Array also entered additional spectrum sales expected to result in aggregate proceeds of $178 million, and its board declared the $23.00 special dividend alongside the T-Mobile close. The final purchase-price adjustment on the T-Mobile transaction, due roughly 180 days after 1 August 2025, is the third unresolved item. All three are contingent; none of the three is evidence of cash received.

The operating base underneath the transactions

The continuing-operations figures isolate what the residual business earns. Third quarter 2025 total operating revenues from continuing operations were $47.1 million against $25.7 million a year earlier; net income attributable to Array shareholders from continuing operations was $108.8 million, or $1.25 diluted per share; and site rental revenues were $45.838 million against $25.669 million (quarterly results). The T-Mobile master licence agreement commenced on 1 August 2025 and helped drive a 68% increase in site rental revenues excluding non-cash amortisation. Anthony Carlson was appointed President and CEO effective 16 November 2025.

The full year sharpens the picture. Total operating revenues from continuing operations were $163.0 million for 2025 against $102.9 million in 2024, and net income attributable to Array shareholders from continuing operations was $169.7 million, or $1.94 diluted per share, compared with a loss of $85.9 million, or $1.00 per share, in 2024 (annual results). Interest expense from continuing operations rose to $28.222 million from $12.405 million, equity in earnings of unconsolidated entities was $173.754 million, and interest and dividend income was $18.917 million. Long-term debt, net, fell to $670.258 million at 31 December 2025 from $1,201.725 million a year earlier, with a current portion of $4.063 million.

Two cautions belong with those numbers. First, a net income figure that includes the gain mechanics of a divestiture year is not a run-rate. Second, $173.754 million of equity in earnings of unconsolidated entities is a large share of a $169.7 million net income result, which means the reported profit depends materially on interests Array does not control — the same noncontrolling investment interests the closing disclosure listed among retained assets. The record does not establish the cash-flow quality of those interests.

Control, buybacks and the direction of the cash

TDS owned 82.0% of Array's equity as of 30 September 2025, and as of 31 December 2025 a majority of Array's outstanding Common Shares and all of its outstanding Series A Common Shares were held by TDS. Special dividends are paid pro rata, so on the two distributions documented here the controlling shareholder received the large majority of the cash, before any question of minority preference arises.

Share repurchases moved in the opposite direction in scale. During 2025 Array repurchased 328,835 Common Shares for $20.9 million at an average cost of $63.49 per share, and as of 31 December 2025 the cumulative number of Common Shares authorised to be purchased was 658,107, with no expiration date; the pricing committee has specified no increase since 2016 (equity note). Roughly $21 million of buybacks alongside roughly $1.99 billion of dividends is not a balanced capital-return programme. It is a distribution programme with a small repurchase facility attached.

That asymmetry is the most testable proposition in this article. A controller that wishes to raise its proportional economic interest buys shares; a controller that wishes to receive cash declares dividends. The documented behaviour is overwhelmingly the second. It does not follow that the first is intended later, and nothing in the record establishes a minority-protection mechanism, a valuation of retained spectrum, or a commitment to reinvest sale proceeds in the tower book.

What would falsify the benign reading

If the Verizon sale closes at approximately $1,000 million and the proceeds are used to fund further dividends rather than to build durable rent, the sequence becomes recognisably a liquidation path spread over time. If a material share of the approximately 1,800 interim tower leases is cancelled by T-Mobile before or at the 30-month mark, the durability case rests almost entirely on the 2,015-tower minimum and the roughly 600 extended colocations — a smaller base than the headline tower count suggests.

If instead the long-dated leases fill, renew and price upward, and the noncontrolling interests convert into distributable cash, the residual company can be judged as an infrastructure landlord rather than a liquidating balance sheet.

The next observable conditions are specific. The settled T-Mobile purchase price after the roughly 180-day adjustment. A closing date and final proceeds for the Verizon licences. Disclosure of how many interim tower leases convert to long-term terms. A statement of cash flow that shows recurring site rental income exceeding dividends paid. Any of those four would move the judgement materially, and all four are absent from the record today.

For the entity itself, the (directory entry) remains the reference point as the reporting position develops.
