TowerNorth Adds Growth Capital for Wireless Expansion

TowerNorth's next tower may begin as a carrier requirement, a developer partnership or an acquisition target. The company has added the financing to pursue all three without pretending they move on the same clock.

TowerNorth is financing that distance. The wireless-infrastructure developer and owner announced on September 17, 2026 that it secured additional growth capital from Berkshire Partners and closed a new debt facility. Financial terms, the lender and the facility's structure were not disclosed.

The useful signal is the range of options the financing supports. TowerNorth plans to put capital into build-to-suit and strategic tower development, developer partnerships and selective acquisitions, letting the company choose among new construction, shared development economics and operating assets as carrier requirements move across markets.

What TowerNorth Announced

The transaction adds both equity support from Berkshire Partners and debt capacity to TowerNorth's balance sheet. The company did not assign the deal a venture-style round label, disclose the amount of either component or identify the debt provider, so the financing is best understood as an undisclosed growth-capital package rather than a numbered Series round.

TowerNorth said the capital will strengthen financial flexibility and support continued expansion. That language matters because the company's growth plan contains several businesses with different timing: building a new site can require a long approval and construction path, a developer partnership can distribute cost and execution responsibility, and an acquisition can add an operating asset more quickly but at a negotiated price.

Berkshire Partners first announced a majority growth investment in TowerNorth in 2023. That transaction also had undisclosed terms, with founding investor Wincove Private Holdings reinvesting at the time. The 2026 announcement confirms Berkshire's additional investment but does not establish Wincove's current ownership or any change in TowerNorth's board.

A Portfolio That Has More Than Tripled

TowerNorth reports that its portfolio grew from 64 towers when Berkshire invested in 2023 to 231 towers by September 2026. The company also says it acquired 28 strategically positioned towers since the beginning of 2026 while expanding its development capabilities and building a larger pipeline of new tower and colocation opportunities.

Those figures are company-reported, not independently audited in the public sources reviewed. They still give the new financing a concrete operating context: this is follow-on capital entering a platform that says it has already added 167 net towers since the sponsor relationship began, with acquisitions accounting for at least part of the recent expansion.

The mix matters more than a single growth percentage. A newly developed tower reflects site selection, carrier demand, zoning, engineering and construction work, while an acquired tower brings an existing asset and the possibility of additional tenants through colocation. TowerNorth has not disclosed how many of its 231 towers were built, bought or sold during the full period, so public readers cannot yet compare the economics of those paths.

The Product Is an Operating Site

TowerNorth was founded in 2012 by Josh Delman and Bert Stern. Stern is the current CEO, and the company's official leadership page lists Tim Jaki as COO, Josh Mossey as CFO, Tom Reese as SVP of Sales and Pablo Herrera as VP of Corporate Development.

The company develops, owns and operates wireless infrastructure in the United States and Europe. Its customer proposition spans build-to-suit tower development, strategic relocations, colocations, acquisitions and partnerships with other developers, supported by local teams that manage the regulatory and physical details of bringing a communications site online.

That local work is not administrative decoration around the asset. A carrier may know exactly where coverage or capacity is weak, but the tower company still has to assemble site rights, municipal approvals, engineering, utilities, construction and tenant installation into one working location. Capital pays for the process; execution determines whether the asset reaches traffic before the need moves somewhere else.

Why Wireless Infrastructure Still Needs More Sites

The financing arrives while U.S. policymakers are still focused on the mechanics of network buildout. In a 2025 wireless-infrastructure proceeding, the Federal Communications Commission examined ways to accelerate tower deployment, densification and upgrades, including the state and local approval processes that can delay projects.

The FCC's underlying logic is straightforward: carriers can increase network capacity with more spectrum, more efficient technology or denser infrastructure. Spectrum is finite and technology gains are uneven, which keeps macro towers and smaller wireless facilities relevant when networks need to reuse spectrum and serve more traffic.

For TowerNorth, that creates demand and friction at the same time. The market needs additional sites, but each site must still move through local conditions that do not scale like software. Berkshire's additional equity and the new debt facility expand the number of opportunities TowerNorth can pursue; they do not remove the work required to turn those opportunities into operating assets.

Berkshire's Digital-Infrastructure Bet

Berkshire's Drew Walker described TowerNorth as the kind of digital-infrastructure business the firm seeks: mission-critical assets, long-term demand and a management team able to build at scale. Walker is a Managing Director focused on technology and digital infrastructure, and Berkshire has previous experience across towers, fiber, data centers and related communications assets.

The investor is currently deploying from Fund XI, which has approximately $7.8B in commitments. That larger capital base can support follow-on investments, but the TowerNorth announcement does not identify which Berkshire vehicle funded the transaction or disclose the check size, valuation or ownership impact.

This leaves the investment thesis visible while its price remains private. Berkshire is backing the belief that carrier demand, network densification and local development expertise can support a larger independent tower platform. TowerNorth now has to decide which prospective sites deserve construction capital, which developers deserve a partnership and which operating towers are worth acquiring.

What the New Capital Changes

Financial flexibility can shorten the distance between seeing an opportunity and funding it. TowerNorth can enter carrier conversations with more ability to finance a build, support a local developer or move on a tower acquisition without forcing every opportunity through the same capital lane.

The next evidence will come from the portfolio rather than the announcement. TowerNorth has not disclosed revenue, tenant density, acquisition returns, construction timing or how it will divide the capital, and the debt facility introduces obligations whose price and restrictions remain private.

What is public is a platform that says it grew from 64 to 231 towers in three years and has now added financing for several more routes to scale. Each route eventually arrives at the same unforgiving handoff: a carrier needs capacity in a particular place, and TowerNorth has to make the site real before that need becomes someone else's tower.
