Tuas Limited (ASX:TUA) shares touched a 52-week low during the Trading session on 26 October 2026, changing hands at $1.27, a fall of 30.50% on the day. Tuas is an ASX-listed telecommunications group whose wholly owned subsidiary, Simba Telecom Pte Ltd, operates in Singapore under a facilities based operator licence regulated by the Infocomm Media Development Authority (IMDA). The company lodged an announcement with the ASX on the same day, detailing a regulatory notice received by that subsidiary.

Show Cause Notice Received by Simba

In its 26 October 2026 announcement, Tuas said that at about 7:30pm Sydney time on Friday 23 October 2026 Simba received a Notice to Show Cause from the IMDA, asking why the regulator should not make certain findings against it. The notice states that the IMDA has not yet decided whether action should be taken or, if so, what form it would take.

The company reported that the matters summarised in the notice include allegations that Simba used dynamic spectrum sharing on the 2100 MHz band at about 133 sites for intermittent periods in 2022 and 2023, allowing the band to carry both 4G and 5G traffic when it was authorised for 5G only, and that it used 2340-2360 MHz spectrum at about 92 sites between 2023 and 2026 without authorisation.

Further Allegations and Possible Regulatory Actions

The notice also alleges that the spectrum deployments were intentional and approved by Simba's senior management, that 5G indoor radio access network equipment was deployed at two locations in 2023 before IMDA authorisation was given on 14 November 2023, and that Simba did not fully comply with a production order, with the failure to produce documents described as deliberate. The IMDA has also raised concerns about deficiencies in Simba's governance and compliance culture.

Potential actions listed in the notice include suspending or cancelling the spectrum right, financial penalties not exceeding the higher of 10% of annual turnover of the relevant part of Simba's Business or $1 million, written orders to secure licence compliance, cancellation, suspension or reduction of the licence period in certain circumstances, and additional regulatory obligations through modified licence conditions or directions. Tuas stated that no findings have been made or confirmed and that it does not intend to comment further while the matter remains under consideration.

About Tuas and Its Business

Tuas Limited is headquartered in Macquarie Park, New South Wales, and is listed on the ASX under the code TUA. Its Singapore-based subsidiary, Simba Telecom, is a mobile network operator that holds spectrum rights and a facilities based operator licence granted by the IMDA, which is the body now seeking Simba's representations. The company's announcement concerns this regulated business and is the only item in the release covering operations.

Spectrum rights are the licensed use of defined radio frequency bands, and mobile operators generally deploy them across networks of cell sites. The announcement refers to the 2100 MHz and 2340-2360 MHz bands and to dynamic spectrum sharing, a technique that allows a single band to carry more than one generation of mobile technology, such as 4G and 5G, at the same time. The IMDA is the Singapore statutory authority that administers telecommunications licensing and enforcement.

Risks

The announcement identifies several uncertainties. The IMDA has not stated what action, if any, it will take, and the range of Options described includes financial penalties tied to turnover, suspension or cancellation of spectrum rights, and licence modifications. The notice further records concerns about governance and compliance culture, which the regulator considers may Warrant further obligations. Simba's response is due on 16 November 2026, and Tuas has said it will not provide further comment during the process, so additional detail may be limited until the regulator communicates its position.

Catalysts on Investors' Radar

The first dated item is the 16 November 2026 deadline for Simba to lodge its response to the Show Cause Notice. After that, the next communication will come from the IMDA, which has not indicated a timetable. Any announcement by Tuas about the regulator's decision, or about changes to licence conditions or spectrum rights, would be disclosed to the market in line with its continuous disclosure obligations.

Final Perspective

Tuas shares touched a 52-week low on the same day the company disclosed the IMDA notice. The notice lists specific allegations about spectrum use, equipment deployment, a production order and governance, together with a range of potential outcomes, while the regulator itself has made no findings. The company's response date of 16 November 2026 is the next defined point in the process.
