ATEX Q4 2025: $116M Contracted Proceeds Signal Utility Spectrum Demand Surge
Antarex’s fiscal Q4 saw contracted proceeds hit a record $116 million, driven by outsized utility demand for private 900 MHz LTE spectrum and a heavily oversubscribed Accelerator program. Management is leveraging a capital-light, customer-funded deployment model and a streamlined cost base, while regulatory momentum for expanded spectrum remains a key tailwind. With a $3 billion pipeline and active strategic review, ATEX enters FY26 with high cash visibility and a sharpened focus on scaling its industry leadership.
Summary
- Accelerator Program Oversubscription: Utility appetite for 900 MHz LTE far exceeded supply, validating Antarex’s market leadership.
- Cost Structure Reset: Operating expense run rate cut by $4 million without impacting customer delivery or growth initiatives.
- Regulatory Tailwinds: FCC momentum on 5x5 MHz expansion could cement ATEX’s positioning and unlock new growth vectors.
Performance Analysis
Antarex delivered its best year for contracted proceeds, securing $116 million in new spectrum sales agreements, primarily with Encore and LCRA, covering 93 percent of Texas counties. The company also accelerated cash collections, with $44 million in milestone payments from Encore and $8.5 million from Ameren, plus an early $34 million delivery. ATEX exited Q4 with $47 million in cash and zero debt, and has $150 million in outstanding contracted proceeds—$80 million of which is expected in FY26—providing strong cash flow visibility.
Operationally, the company’s cost structure overhaul reduced its operating expense run rate by roughly $4 million from the first half of FY25, improving efficiency and cash generation without sacrificing customer service or strategic priorities. The capital-light deployment model, where customers fund network builds, continues to support scalable growth and margin preservation.
- Cash Flow Visibility: $150 million in contracted proceeds outstanding, with $80 million expected in the next fiscal year.
- Pipeline Depth: A $3 billion pipeline and a proven regional deployment model set the stage for replication nationwide.
- Customer-Funded Deployments: Capital-light model allows scaling with minimal capex, supporting margin resilience.
These results reinforce ATEX’s ability to translate utility demand into contracted revenue and cash flow, while maintaining financial discipline and strategic optionality.
Executive Commentary
"As of today, we are oversubscribed with utilities that are in active discussions and negotiations for the $250 million of spectrum we made available as part of the program. What we are seeing is clear. The demand for 900 megahertz LTE continues to be strong."
Scott Lang, President and CEO
"We closed the fourth quarter of fiscal year 25 with over $47 million in cash and no debt, a position we view as a meaningful strategic advantage. Additionally, we have approximately $150 million of contracted proceeds outstanding, with $80 million expected in fiscal 26. These are not potential deals. They're binding commitments that provide clear visibility and confidence in our future cash flow."

Strategic Positioning
1. Utility Market Penetration and Pipeline Expansion
ATEX’s regional deployment model, proven in Texas, is positioned for national replication, with 93 percent of Texas counties now covered by contracted spectrum agreements. The company’s $3 billion pipeline reflects both pent-up and ongoing demand, and the Accelerator program’s oversubscription demonstrates urgency among utilities to secure private LTE spectrum for digital grid modernization.
2. Ecosystem and Partner Integration
Major technology partners—Ericsson, Nokia, GE—have developed bespoke offerings for the Accelerator program, enabling utilities to fast-track network deployment and integration. The InterX Active ecosystem now exceeds 140 participants, with recent entrants like Digi International launching edge computing gateways that enhance data and AI-driven use cases for utilities. This ecosystem approach deepens customer stickiness and broadens the addressable market for value-added solutions.
3. Regulatory Advocacy and Spectrum Roadmap
ATEX is actively engaged with the FCC on the pending rulemaking to expand the 900 MHz band to a 5x5 MHz configuration, which would increase capacity and future-proof utility networks. Widespread industry support—including from technology heavyweights and utility associations—bolsters the likelihood of a favorable outcome, which could accelerate adoption and raise switching costs for competitors in adjacent spectrum bands.
4. Cost Discipline and Capital Allocation
Management delivered a $4 million reduction in operating expenses without impairing growth, demonstrating a commitment to long-term financial discipline. The capital-light, customer-funded model minimizes balance sheet risk and maximizes cash conversion, supporting both organic growth and strategic flexibility as the company evaluates options in its ongoing Morgan Stanley-led review.
Key Considerations
Antarex’s Q4 performance highlights a convergence of utility demand, regulatory momentum, and disciplined execution, but also surfaces competitive and strategic questions that investors should weigh.
Key Considerations:
- Utility Demand Outpacing Supply: The oversubscription of the Accelerator program signals structural demand, but also raises questions about future pricing power and the pace of contract conversion.
- Regulatory Catalysts as Double-Edged Sword: While FCC progress on 5x5 MHz is a tailwind, any delay or adverse outcome could slow adoption or open the door to alternative spectrum providers.
- Competitive Dynamics in Adjacent Bands: The emergence of 800 MHz as an alternative for utilities could pressure ATEX’s market share, though management remains confident in its economics and deployment track record.
- Strategic Review Uncertainty: The ongoing Morgan Stanley-led review introduces potential for M&A or other capital allocation shifts, but also creates a period of uncertainty regarding long-term direction.
Risks
Key risks include regulatory delays on 5x5 MHz approval, increased competition from adjacent spectrum bands (notably 800 MHz), and the possibility of utility customers deferring decisions pending further clarity on technology standards or regulatory outcomes. While the contracted revenue base is solid, pipeline conversion remains exposed to macro cycles and utility budget priorities.
Forward Outlook
For Q1 FY26, Antarex expects:
- Continued cash collections from $80 million in contracted proceeds.
- Ongoing cost discipline and capital-light growth execution.
For full-year FY26, management reiterated focus on:
- Growing contracted proceeds above FY25’s record $116 million.
- Maintaining a debt-free balance sheet and maximizing cash conversion.
Management highlighted several factors that will shape FY26:
- Accelerator program conversion and new contract signings.
- FCC decision timing on 5x5 MHz rulemaking.
Takeaways
Antarex enters FY26 with a robust contracted backlog, high cash visibility, and a sharpened focus on scaling its leadership in utility private LTE.
- Accelerator Demand Validates Model: Utility oversubscription and partner momentum reinforce ATEX’s value proposition and market position.
- Cost Structure Reset Provides Margin Cushion: Operating expense reductions and customer-funded deployments support cash flow and strategic flexibility.
- Regulatory and Competitive Watchpoints: Investors should monitor FCC outcomes and adjacent spectrum developments as key inflection points for growth and market share.
Conclusion
Antarex’s Q4 results confirm structural demand for utility-grade spectrum and demonstrate disciplined execution on cost and capital allocation. While regulatory and competitive uncertainty remain, the company’s contracted base and ecosystem approach position it well for continued growth and strategic optionality in FY26.
Industry Read-Through
ATEX’s experience highlights a broader utility sector shift toward private, secure wireless networks as grid modernization accelerates. The rapid customer ramp in the Accelerator program and the integration of technology partners suggest that utilities are moving past pilot phases and scaling digital infrastructure investments. FCC rulemaking on expanded spectrum is a key watchpoint for the entire smart grid and industrial IoT ecosystem, as regulatory clarity could unlock further capital spending and accelerate vendor adoption cycles. Competitors in adjacent bands and technology vendors should prepare for heightened customer expectations around bandwidth, security, and deployment speed as the market evolves beyond legacy solutions.
