Etherstack (ASX:ESK) logged preliminary results for the 2025 fiscal year, reporting a 70% surge in revenue to US$10.1 million.
The performance landed at the top end of market guidance and was supported by US$12 million in cash receipts, marking the company’s eighth consecutive year of positive operating cash flow.
The growth is primarily attributed to the deployment of Etherstack’s world-leading "InterWorking Function" technology, a mission-critical software bridge that allows traditional public safety radio networks to communicate seamlessly with modern 4G and 5G carrier networks.
Looking ahead, management has issued a confident revenue guidance range of US$16.2 million to $17.5 million, representing a further 60% year-on-year increase.
The trajectory is underpinned by a record US$40 million order book, driven largely by major long-term contracts with AT&T FirstNet in the United States and the UK Home Office’s Emergency Services Network.
