I'm reading mixed messages about potential penalties
AFR said there is potential for revoking or suspending the simba spectrum license. However lots of other sources said penalties can be a fine with fixed amount or percent of turnover which is best case scenario.
I'm going to bet the latter and I think that AFR article spooked investors into selling. However i would recommend to do your own research and make up your own mind as i don't know enough of the Singapore regulations and punishment. I also don't believe Teoh is this deliberate in using spectrum without authorisation for financial gain.
For the record, Teoh did me a favour in the past by buying out my holdings in Telemedia (a dog stock I had during the dot com bust and neglected to do anything about as I was sitting on losses) and bringing the company into TPG where I managed to make up my losses and sell few years ago. If it wasn't for Teoh I would be sitting on massive losses in Telemedia so I have huge respect for Teoh.
