What Harmoni Towers does

Harmoni Towers designs, builds, owns, and operates a U.S. nationwide portfolio of macro cell tower infrastructure, including build-to-suit towers, colocations, concealed structures, monopoles, self-support towers, and guyed towers. The company is the second-largest privately-owned wireless tower operator in the United States, with 2,000+ constructed and in-development sites — cited elsewhere as more than 3,000 owned and managed — distributed across 40+ states with stated saturation in the Southeast, Midwest, and West Coast. Its customer base consists of all four major U.S. wireless carriers (AT&T, T-Mobile, Verizon, DISH), regional carriers, WISPs, non-traditional providers, and the U.S. Department of Defense via a direct AAFES partnership that delivers broadband infrastructure across 200+ military bases.

The business operates four monetization streams: (1) recurring tower lease and colocation rental income on multi-year, escalated contracts with carrier tenants; (2) purpose-built build-to-suit tower construction delivered end-to-end from site acquisition through ongoing operations, where Harmoni can fully fund colocation builds inclusive of gear and installation as an option to offset customer CAPEX; (3) a ground lease buyout program that purchases leasehold interests from property owners for one-time or structured cash inflows; and (4) managed services revenue from military base broadband deployment. Exclusive tower development rights along BNSF Railway's 65,000-mile corridor (and a parallel Union Pacific arrangement) provide unique real estate access not available to most peers. Pricing is not publicly disclosed and is negotiated site-by-site.

The company is a Delaware LLC privately held by Palistar Capital LP, which acquired the predecessor Uniti Towers business from Uniti Group in June 2020 and has since committed to deploy more than $1 billion in equity and debt. Harmoni completed its transformative acquisition of Parallel Infrastructure from Apollo in late 2022, closed a $620 million private placement in November 2025 (the largest cell tower bond issuance in U.S. history), and recently integrated Inorsa's AI-powered document automation across the portfolio for internal operational efficiency. Direct enterprise field sales — six regionally assigned representatives plus a national accounts team — is the sole go-to-market motion; no resellers, marketplaces, or third-party distribution are used.

Revenue model

1. Tower Lease / Colocation Rental Income: Recurring monthly rental income from wireless carriers and service providers leasing space on owned and managed tower assets. Tenants include national carriers, regional carriers, WISPs, and non-traditional providers. Lease agreements are long-term and typically structured as multi-year contracts with escalation clauses.
2. Build-to-Suit Tower Construction: Purpose-built tower construction services delivered to carrier specifications. Harmoni provides end-to-end site acquisition, creative engineering, on-schedule construction, and ongoing operations. Revenue recognized as projects are completed. Carriers may elect Harmoni to fully fund colocation build inclusive of gear and installation costs.
3. Ground Lease Buyout: Program enabling property owners to accelerate income potential from tower ground leases, including possible upfront lump-sum cash buyout. Generates one-time or structured cash inflows by purchasing the leasehold interest from property owners.
4. Military Base Infrastructure Services: Broadband infrastructure deployment on U.S. military bases in partnership with AAFES (Army Air Force Exchange Services), Department of the Air Force, and Department of the Army. Revenue derived from carrier agreements to provide enhanced coverage on bases.
