trading halt, page-38

Good or bad news, I would usually fail to see why this necessitates a trading halt.

There is only but one reason I can see which concerns a change in company focus.

With relevance to CKK's direction that could only mean ditching the CLRS. If it were positive it would not trigger an announcement concerning it's "commercial viability". They've already spent plenty of time ramping that up over the last few years.
Obviously they're not ditching the GT3000 as they've already announced pending work for it.

Unfortunately pretty obvious imo
