Scarce utility spectrum, still a hard sale
- Anterix collected $127.0 million in contracted proceeds in fiscal 2026, far above its first $80 million target.
- The FCC expanded the 900 MHz broadband segment from 6 MHz to 10 MHz, and new utilities quickly signed 10 MHz deals.
- The company still had $50 million of contracted proceeds outstanding at fiscal year-end.
- Anterix has zero debt in the internal view and began buying back shares, with 43,175 shares repurchased for $1.0 million.
- The stock price remains the hard part, since the business has valuable assets but uneven revenue timing.
Proof, then patience
Anterix owns licensed 900 MHz spectrum. That is radio space utilities can use to build private wireless networks for grid controls, sensors, field crews, and backup communications. The bull case is that this spectrum is scarce, useful, and now easier to sell after the FCC expanded the broadband segment from 6 MHz to 10 MHz.
Fiscal 2026 gave the bull case real proof. Anterix collected $127.0 million of contracted proceeds against an original $80 million target. It signed four new utilities in a three-month span: CPS Energy, Texas New Mexico Power, Benton PUD, and NorthWestern Energy. Two of those customers moved straight to 10 MHz agreements after the FCC ruling.
The accounting also showed the value of the spectrum conversion plan. Anterix recorded a $105.4 million gain on exchanging narrowband licenses for broadband licenses in 219 counties, plus a $34.8 million gain on sales tied to delivered licenses in 155 counties. It also started a small buyback, repurchasing 43,175 shares for $1.0 million.
The bear case is timing and price. Utility decisions can take years, and revenue can look lumpy because licenses are sold or leased county by county. The market also appears to give Anterix credit for a lot of future wins already, so new deals and backlog conversion need to keep coming.
Sell the air rights
Anterix makes money by selling or leasing 900 MHz broadband licenses to utilities and other critical infrastructure customers. A utility can then use that spectrum for its own private LTE or 5G-style network. Anterix does not usually run the customer network itself.
The company has moved from a mainly lease-based model to a broader model. It now clears spectrum, secures broadband licenses, sells or leases those licenses, and tries to attach services around the network build. Spectrum sale agreements after December 31, 2025 are treated as ordinary-course sales, with revenue and cost of sales shown on a gross basis under ASC 606.
The key cost is making the spectrum usable. Anterix must clear existing users, retune systems where needed, and get the FCC to grant broadband licenses. If that work costs more or takes longer than planned, cash receipts can slip and customers may have contract rights tied to delayed delivery.
Management has also stopped using early discounted accelerator pricing and moved to custom pricing. That can lift value if demand keeps rising. It can also slow deals if utilities push back or find cheaper spectrum alternatives.
From spectrum to services
900 MHz broadband spectrum
This is the core asset. Anterix sells or leases licensed spectrum to utilities that want private wireless networks for grid operations.
10 MHz 900 MHz configuration
The FCC expanded the band from 6 MHz to 10 MHz. Anterix has already signed customers using this wider setup, which can support more capacity.
Long-term utility contracts
Contracts with utilities such as Oncor, LCRA, TECO, CPS Energy, and others drive cash receipts. The main issue is that delivery depends on clearing and licensing work.
TowerX
TowerX helps utilities find and use tower sites with preset terms and support. It was launched with Crown Castle to speed network buildouts.
CatalyX
CatalyX handles SIM provisioning and connectivity management. The goal is to make private wireless networks easier for utilities to start and operate.
Link Global satellite testing
Anterix is testing how enterprise satellite links could work with terrestrial private networks. This is early, but it could add coverage for remote infrastructure.
One business, one revenue line
Anterix reports as one unified business. For fiscal 2026, the 10-K revenue table shows spectrum revenue of $6.5 million and no separate reported revenue from TowerX, CatalyX, or satellite testing.
What can break
Utility sales stall
High impact · Medium oddsUtilities are large, careful buyers. They often need board approval, regulator comfort, capital budgets, and vendor plans before they sign. Anterix had a better recent signing pace, but a few slow quarters could make the growth story look weaker.
Clearing and FCC delays
High impact · Medium oddsAnterix must clear incumbent users and get broadband licenses from the FCC before some customer payments are safe. The October to November 2025 federal government shutdown slowed FCC licensing work, showing that outside events can delay delivery. Higher clearing costs would also reduce the value of each deal.
800 MHz competition
Medium impact · Medium oddsT-Mobile agreed to sell its 800 MHz spectrum holdings, and that spectrum could be offered to some of the same utility customers. Anterix still has a strong 900 MHz position, but another low-band choice could weaken pricing. This matters more now that Anterix has ended early discount pricing.
Services fail to attach
Medium impact · Medium oddsTowerX and CatalyX are meant to make Anterix more than a spectrum seller. If utilities buy spectrum but skip the add-on services, recurring revenue may stay small. Larger tower, telecom, and systems vendors already have deep utility relationships.
Valuation outruns cash flow
Medium impact · Medium oddsAnterix owns valuable spectrum, but recognized spectrum revenue was only $6.5 million in fiscal 2026. Gains from license exchanges and asset sales can be large, yet they do not prove a smooth recurring revenue base. If investors pay for years of future utility wins, the stock can fall even while operations improve.
In one breath
What does Anterix actually sell?
Anterix sells or leases licensed 900 MHz spectrum rights. Utilities use that spectrum to build private wireless networks for grid operations, field work, sensors, and secure communications.
Why did the FCC 10 MHz ruling matter?
The ruling expanded the 900 MHz broadband segment from 6 MHz to 10 MHz. A wider channel can make the spectrum more useful, and Anterix said new utilities moved directly to 10 MHz agreements soon after the ruling.
Is Anterix profitable now?
Anterix reported net income of $90.6 million in fiscal 2026, helped by large gains on license exchanges and asset sales. The core spectrum revenue line was much smaller at $6.5 million, so investors should focus on cash receipts and new contracts.
What is the biggest risk for ATEX stock?
The biggest risk is that utility contracts, FCC licenses, and spectrum clearing take longer than expected. The stock also needs enough future deals to support its valuation.
