Tuas shares fell as much as 40% in October 2026 as its Singapore subsidiary, Simba Telecom, faced possible regulatory penalties over alleged unauthorized use of radio frequency bands. The Infocomm Media Development Authority has issued a Notice of Reasons, with Simba due to respond by November 16 before the regulatory process moves forward.
Key Takeaways
- IMDA is considering action over alleged unauthorized spectrum use during periods in 2022 and 2026.
- Possible sanctions include financial penalties and suspension or revocation of spectrum usage rights.
- Simba's response deadline is November 16; the potential sanctions are not a completed enforcement decision.

Why Tuas shares came under pressure
The sharp share-price decline accompanied news that IMDA was moving toward enforcement action against Simba. The notice concerns alleged use of frequency bands that had not been authorized for the operator.
The distinction between a notice and a final decision matters: Simba has an opportunity to respond, and the eventual scope of any sanctions remains unresolved.
| Item | Details |
|---|---|
| Regulator | Infocomm Media Development Authority, Singapore |
| Earlier public disclosure | May 18, 2026: IMDA disclosed that Simba could have used unassigned frequency bands. |
| Periods covered by allegations | Multiple periods in 2022 and 2026 |
| Response deadline | November 16, 2026 |
Potential penalties extend beyond a fine
The possible financial penalty is up to S$1 million or 10% of Simba's annual revenue. The potential measures also include suspension or revocation of spectrum usage rights.
That makes the proceedings an operational issue as well as a possible financial cost for Tuas. Spectrum rights determine which radio frequencies a mobile operator may use, so restrictions could affect Simba's ability to provide services. The notice does not establish that such restrictions will be imposed.
Singapore had outlined the spectrum risks in July
In its July 7, 2026 parliamentary response on spectrum safeguards, Singapore's Ministry of Digital Development and Information said mobile operators must use only their assigned spectrum. Unauthorized use can interfere with other services and give operators an unfair advantage over competitors.
That response described the investigation as ongoing at the time and said IMDA would ensure Simba continued meeting licence obligations and service commitments. It provides background on the rules and investigation, rather than confirmation of the subsequent October notice or proposed penalties.
Conclusion
The next scheduled milestone is Simba's November 16 response deadline. For Tuas, the unresolved question is whether IMDA ultimately imposes a financial penalty, restrictions on spectrum rights, or both.
