What is the Etherstack US telco project expansion?

Etherstack's US subsidiary has agreed an extra US$1.8 million of work on its main project with a Tier 1 US telecommunications carrier. It covers new feature requests, extra services for deployments and more connections to public safety agencies.

When will Etherstack record the extra US$1.8 million?

Most of the extra revenue for its MCX business unit is expected to be booked in the next 90 days. It will add to the current financial year ending 31 December 2026 and the following year.

What is a Tier 1 telecommunications carrier?

It is a large network operator, and the announcement uses the term for Etherstack's main US customer on this project. The carrier has not been named in the announcement.

What is Etherstack's LMR-IWF product?

The company calls it a world leading 3GPP LMR-IWF product, and the extra US$1.8 million of work relates to it. The announcement does not explain the product further.

Has Etherstack won similar project increases before?

Yes, in August 2026 a £0.5 million change to its UK Government project also lifted ongoing support and maintenance fees. Management says projects like this often grow in features, length and revenue.

Etherstack adds US$1.8m uplift to Tier 1 US telco project

Etherstack (ASX:ESK) has agreed a US$1.8m uplift to its primary project with a Tier 1 US telecommunications carrier. Its US subsidiary, Etherstack Inc., agreed the expansion to the project announced to the market on 11 August 2025.

The additional revenue relates to the Company’s “world leading 3GPP LMR-IWF product” and covers:

New feature requests
Additional professional services associated with deployments

Revenue timing across FY26 and FY27

The additional revenue for the Company’s MCX business unit will predominantly be recognised in the next 90 days. It contributes to both FY26 (financial year end 31 December 2026) and FY27.
