Ted B. Miller Jr. still has towers on his mind

Founders can leave the office without entirely vacating the premises. In February 2024, Ted B. Miller Jr. made his attachment to Crown Castle quite public. More than two decades after his time running the company, he wanted to return as executive chairman. He brought three proposed colleagues, a plan for the fiber business and strong views about how towers should be managed. The board declined the invitation to rearrange itself.

Miller pressed on. Through Boots Capital, he sought four seats in a shareholder vote. The episode had the ingredients of an awkward reunion: shared history, familiar faces and very different accounts of how things had gone. Miller regarded his experience as an argument for his return. Crown Castle’s directors regarded the distance between his tenure and the present company as a reason to resist it.

The shareholders settled the immediate question in May. They elected the company’s twelve nominees. Miller’s slate went home without a seat. Yet the campaign revealed something more durable than an appetite for a particular chair: he was still preoccupied with the machinery, measurements and economics of the tower business.

A business built for sharing

Miller came to infrastructure with an education in business and law. He earned his BBA at the University of Texas at Austin in 1973 and his JD at Louisiana State University in 1976. His career began at Ernst & Young. By 1986, he had founded Interstate Realty Corporation, a real estate development and consulting company. Before the tower portfolio came the property business.

In 1994, he co-founded Castle Tower Corporation, a predecessor of Crown Castle. The attraction of shared infrastructure is wonderfully unromantic. Different wireless operators can put equipment on the same structure. The tower owner provides space and services; the carriers attend to their networks. Steel, unlike a mobile subscriber, can maintain several relationships at once without anybody feeling particularly betrayed.

Crown Castle’s early history moved quickly. The business began with 133 towers. It went public on Nasdaq in 1998 with approximately 1,400. Miller had become chief executive in November 1996; in June 1999, he also became chairman, succeeding Carl Ferenbach. A company assembled around physical sites was acquiring the capital and institutional machinery to buy many more.

Sites owned and managed at year end.

The early portfolio had become an international operating business. Acquiring the towers was only part of the job.

The Castle acquires a passport

Britain gave the enterprise a different kind of reach. Crown Castle’s UK operations included the BBC’s television and radio transmission networks. A 1999 agreement added 821 One 2 One towers, with arrangements for further construction and sharing. The business involved operating infrastructure that other people depended on, across contracts and markets that rewarded attention to the particulars.

By late 1999, the rush to acquire carrier portfolios was giving way to the work of integrating and leasing them. Speaking at an industry gathering in Las Vegas, Miller described Crown Castle as substantially through aggregating the major carrier footprints. The obvious next question was how to make all those acquired sites function as a business.

The scale was visible by the end of 2000: 12,918 sites owned and managed, including operations in the United States, the United Kingdom and Australia. Growth had produced a considerable administrative assignment. Each additional site came with equipment, tenants and operating obligations. A portfolio looks clean on a chart. On the ground, it has bolts.

John P. Kelly succeeded Miller as chief executive in August 2001. Miller stayed as non-executive chairman until leaving the board in 2002. At the handover, he emphasized revenue growth, margins and capital efficiency. The public company would continue under other executives; the co-founder’s business life would acquire several other addresses.

Aircraft, outsourcing and the years between

Those intervening years deserve more than a parenthesis. Miller’s work included M7 Aerospace, where he was chairman and majority shareholder from 2003 until its sale. The San Antonio company handled aircraft manufacturing, maintenance, engineering and logistics. Elbit Systems of America acquired it in December 2010 for $85 million in cash. Aviation, too, offers ample opportunity to discover the difference between owning an asset and keeping it useful.

Intercomp Technologies, another Miller venture, worked in business process outsourcing across Eurasia. It was sold to Elbrus Capital in October 2013. He also served on the boards of Affiliated Computer Services and Airgas. Staffing and government contracting through 4M HR Logistics added another operating business to the collection.

The variety can make his career sound like a series of departures from telecom. There is a practical connection, though: property, equipment, people and the systems required to organize them recur throughout it. That is a reading of the record rather than a private confession of purpose. His newer businesses make the connection to towers explicit.

At 4M Investments, which he has led since 2001, the interests include commercial property as well as infrastructure and related technology. Office, retail, hotel and distribution space sit alongside the telecom work. The business vocabulary changes between an aircraft service company and a real estate portfolio, but the obligations remain concrete: somebody must maintain the asset, organize the work and make the numbers hold together. That helps give the later enthusiasm for automation a recognizable setting.

The argument gets smaller. Much smaller.

At Visual Intelligence, where Miller is founder and chairman, the proposition concerns detailed digital representations of physical infrastructure. Drone sensors collect data about a tower. Software turns that capture into a model people can measure and use. The company describes its technology in terms of millimeter accuracy, a distinction Miller returns to with the persistence of someone who expects an engineer to check his homework.

His argument starts with the limits of a picture. A drone can produce an attractive view of a structure while leaving an engineering team without the dimensions it needs. In his account, the quality of the captured data determines how much useful analysis and automation can follow. A digital replica earns its keep when it can help answer questions about equipment, structure and available capacity.

In a 2021 interview, he explained the ambition in terms of collecting useful information once and avoiding repeat trips for measurements. His concern extended beyond replacing an inspection visit. Engineers, leasing teams and operators could all benefit from a better account of the same asset. Knowing the tower more precisely might change decisions throughout the company.

“The key is understanding what you have.”

PowerX addresses an adjacent problem. The UK software company announced Miller as a non-executive director in July 2023. Its work applies data science and AI to tower operations, including power management. His public argument there was similarly practical: digitization could help teams manage equipment, maintenance and resource demands across a portfolio. The futuristic vocabulary keeps returning to everyday operating costs.

Four seats, no invitation

These interests help explain the detail of his 2024 Crown Castle campaign. Boots Capital proposed Miller, former Crown Castle finance executive Charles Green, investment banker David Wheeler and Tripp Rice, Miller’s son-in-law and a colleague in his investment businesses. Miller wanted the executive chairmanship. He told an interviewer that he did not want the CEO job.

The plan combined a sale of fiber assets with changes to tower operations, including the use of digital twins and AI. Miller argued that Crown Castle needed people with direct operating knowledge of towers. His proposed valuation and timetable for selling fiber were ambitions, dependent on transactions that had yet to happen. A campaign presentation is allowed a future tense; a completed deal must eventually use the past.

He also defended getting involved in operating detail. Recounting a director’s question about whether his group was too deep in it, he answered: “Yes, we’re in the weeds.” The remark gives his campaign a human voice. After years of company building and investing, he was asking to be judged partly on how closely he examined the work.

The board made a different case. It questioned the relevance of his recent experience and raised concerns about his proposed executive chairman role and the composition of his slate. Crown Castle was already reviewing its fiber business after an agreement with Elliott Investment Management. Disagreement over who should lead the change accompanied the argument about what should change.

The May 22 vote resolved the contest in the board’s favor. In a public company, the founding story can open a conversation. It cannot count the ballots. Miller’s unsuccessful return belongs beside his early achievements because both describe his relationship with an enterprise that had grown beyond its original leadership.

The next tower still needs an owner

There was a later turn. On May 1, 2026, Crown Castle completed the sale of its fiber solutions and small cell businesses for $8.5 billion before adjustments, leaving a tower-focused company. The broad direction resembled one Miller had advocated. The transaction took place under other leadership, on different terms and a different timetable from his proposal. The resemblance is interesting without awarding him someone else’s closing dinner.

Meanwhile, 4M Towers lists him as founder and chairman. The business builds, owns and operates towers, offering leasing, acquisitions and development for carriers. Its stated approach incorporates drones, digital models and automation. Miller’s current work therefore sits on both sides of the question: the physical infrastructure and the information used to manage it.

His story has a pleasingly stubborn continuity. The young public company needed to acquire sites and make them work together. The newer ventures ask how precisely each site can be understood. Years after leaving Crown Castle’s executive office, Miller remains interested in the details at the base of the tower. The view is less ceremonial there. The measurements are rather better.
