Tuas Fell as Much as 40% After Singapore's Spectrum Notice
Tuas shares fell as much as about 40% on Monday after Singapore's regulator accused its unit Simba of unauthorised spectrum use. The alleged use covered about 92 sites from 2023 to 2026. The IMDA could suspend or cancel Simba's licence and fine it the higher of 10% of turnover or S$1 million. Simba has until November 16 to respond.
A regulatory letter sent on a Friday evening became a one-day loss of more than a third of a company's value. Tuas, the ASX-listed owner of Singapore's budget mobile carrier Simba Telecom, fell more than 30% in Monday morning trade, Capital Brief reported, and as much as about 40% at one stage, according to Market Matters, which said the stock hit a fresh 52-week low. Kalkine had it at A$1.27, down 30.5%, around 11 a.m. in Sydney, and the ABC's markets blog listed it about 40% lower at A$1.09 later in the session. The shares peaked at A$7.805 in January; the fall from there now exceeds 80%.
The notice is unusually specific. Singapore's Infocomm Media Development Authority alleges, according to the Business Times account relayed by Redhot, that Simba used the 2349–2360 MHz band at about 92 sites for intermittent periods between 2023 and 2026 without authorisation, and that it used dynamic spectrum sharing at about 133 sites in 2022 and 2023 to run 4G as well as 5G on 2100 MHz frequencies licensed only for 5G. The regulator also alleges that Simba deployed indoor 5G equipment at two locations before approval, did not fully comply with an order to produce documents, and that the spectrum conduct was intentional and approved by senior management. It also cites concerns about the company's governance and compliance culture.
The penalties on the table explain the size of the move. Under the notice, Simba could face suspension or cancellation of its licence and a fine equal to the higher of 10% of annual turnover or S$1 million, Capital Brief reported. A fine is a cost; a licence cancellation would remove the business Tuas exists to run. The IMDA has not made any findings or decided whether to act, and Simba has until November 16 to respond. Tuas said it intends to address the regulator's concerns and will not comment further while the investigation continues.
The market had been warned. Simba has been under investigation since mid-May, Tuas's bid for rival operator M1 was terminated shortly after the review became public, and the company acknowledged intermittent use of unauthorised spectrum in its full-year results, according to Capital Brief. The stock was already down about 73% over 12 months before Monday, the Motley Fool noted, and it left the ASX's large-cap benchmark in the September rebalance. Market Matters called it "firmly in the too hard basket" at around A$1.25.
For traders the lesson is about binary risk. A show cause notice is not a verdict, but it narrows the range of outcomes to a handful of very different ones, from a fine the company can absorb to the loss of its only licence, and the market prices the worst of them while it waits. The gap on Monday's open, with almost no trading at the levels in between, is what that looks like on a chart. The next date that matters is November 16.
