Key highlights:

• A follow-on US$0.83 million order from North American channel partner Daniels Electronics (a subsidiary of Codan) extends a commercial relationship that began with a US$2.3 million contract in December 2023, with full revenue recognition expected in calendar year 2026.

• Full-year 2025 revenue reached US$10.1 million, up roughly 70%, with EBITDA swinging to US$2.02 million at a 20% margin from a loss of approximately US$1.2 million, as recurring revenue climbed 62% to US$3.7 million (38% of total).

• First-half 2026 revenue guidance points to US$7.6–8.5 million, implying full-year FY26 revenue of approximately US$17.2–18.9 million, representing growth near 70% on the prior year, anchored by landmark AT&T (US$20 million over seven years) and UK Home Office (GBP 14.2 million over five years) contracts.

When a radio crackles to life at a burning building or a flooded highway, the software behind that transmission rarely gets a mention. Yet the code that keeps emergency crews talking is quietly becoming a lucrative franchise, and one Sydney-founded microcap is proving the point with unusual consistency.

On 22 June 2026, Etherstack (ASX:ESK) told the market it had secured another North American equipment order worth US$0.83 million. On its own the figure is modest. But it lands amid a year in which the company has upgraded guidance, banked landmark contracts and pushed toward sustained profitability, giving the announcement more weight than the headline number suggests.

Company Overview

Etherstack describes itself as one of the world's leading licensors of wireless technology for the digital land mobile radio (LMR) industry. For more than 25 years it has developed the software and firmware that let mission-critical radio networks function, licensing that intellectual property to equipment manufacturers and, increasingly, selling its own products and support services.

The group specialises in the standards that underpin public safety communications: APCO P25, widely used across North America; TETRA, the European and international workhorse; and DMR. It has also invested heavily in mission-critical push-to-talk (MCPTT) and MCX technology that carries emergency voice, data and video over 4G and 5G networks, positioning it for the industry's shift from dedicated radio to broadband.

Headquartered in Chippendale, New South Wales, and listed on the ASX, Etherstack runs operations across Australia, the United Kingdom, the United States and Japan. Its customers span public safety agencies, defence, utilities, transport and resources, the sectors that cannot afford a dropped call.

Latest News

The June order came from Daniels Electronics Ltd, a North American channel partner and subsidiary of Adelaide-based Codan Limited (ASX:CDA). It is a follow-on to a US$2.3 million contract first announced in December 2023, underlining a durable commercial relationship rather than a one-off sale.

Etherstack said the hardware components are manufactured in Australia before being delivered through its North American operations, and that revenue from the order is expected to be fully recognised in the financial year ending 31 December 2026. Management also flagged the potential for long-term support revenue, the maintenance, software updates and technical service that mission-critical kit typically generates over its life.

Crucially, the company used the update to reaffirm momentum, stating that first-half 2026 revenue was tracking to meet or exceed the guidance it had issued on 28 April 2026. Investors took the news calmly, with the shares nudging higher to around A$0.52 on the day, but the message was clear: the order pipeline keeps refilling.

Why Investors Are Watching

Etherstack has spent years as a promising but loss-making technology story. The 2025 result changed that narrative, showing the operating leverage that a software-led model can deliver once revenue scales past the fixed cost base.

Two marquee deals sit behind the optimism. The company has cited an AT&T engagement worth more than US$20 million over seven years and a UK Home Office agreement exceeding GBP£14.2 million over five years, contracts that give multi-year visibility rare for a company of this size. Management has also set an ambition for annual recurring revenue above US$10 million by FY2028, a target that would fundamentally rerate the business if hit.

Growth Opportunities

The structural tailwind is the global migration of emergency communications from legacy radio onto cellular broadband. Agencies want the reliability of push-to-talk with the data, video and interoperability of LTE and 5G, and Etherstack's inter-working function and MCX software sit precisely at that junction.

Recurring support contracts attached to equipment sales, like the Daniels order, offer a compounding annuity as the installed base grows. Beyond that, further national programs across the US, UK and Australia, deeper penetration of defence budgets, and the long tail of licensing royalties from more than twenty manufacturers all provide avenues to extend the current run of growth.

Risks

Scale remains the central caveat. With revenue around US$10 million and cash near US$2.3 million, Etherstack has limited margin for error, and a single delayed milestone can swing a half-year result given how much revenue is still project-based rather than recurring.

Customer concentration is another watch point: flagship contracts with AT&T and the UK Home Office are powerful, but they magnify the impact should any relationship stall. The group also carries currency exposure, reporting in US dollars while listed in Australia, and competes against far larger communications vendors. As with any microcap, the shares can be thinly traded and volatile.

Industry Outlook

The broader mission-critical communications market is expanding as governments modernise ageing networks and blend traditional LMR with cellular broadband. Public safety, defence and critical infrastructure operators are all lifting spending on resilient, interoperable systems, a trend reinforced by heightened focus on national security and disaster response.

That backdrop plays to Etherstack's specialism. As a standards-based software provider that can plug into multiple manufacturers and carriers, it is positioned to benefit whichever hardware vendor ultimately wins a given tender, a useful hedge in a fragmented but growing sector.

What to Watch Next

The immediate catalyst is the half-year result for the six months to 30 June 2026, where investors will look for confirmation that revenue met or beat the US$7.6 million to US$8.5 million guidance and that profitability held.

Beyond that, the signposts are the pace of recurring revenue growth toward the US$10 million ARR ambition, progress on the AT&T and UK Home Office rollouts, fresh contract wins, and the cash position. Consistent conversion of orders like the Daniels deal into long-term support revenue would be the strongest evidence that the turnaround is durable.

Conclusion

Etherstack's latest North American order will not move the dial on its own, but it fits a pattern that has defined 2026: steady demand, repeat customers and guidance pointing to another year of rapid growth. After a long stretch in the red, the company has finally paired revenue momentum with positive EBITDA.

The investment case still rests on a small balance sheet and lumpy, contract-driven earnings, so caution is warranted. Yet for a business selling into an essential and expanding market, the direction of travel is encouraging. The half-year numbers will show whether the momentum is the real thing.
