I would have thought the test results are paramount for anyone wanting to take up their rights in the SPP. The gamblers, I suppose, might want to double down.

There are so many moving parts what with the merger pending, it's hard to believe anyone other than an insider (or said gambler) would take this thing up. I mean, what will the terms of the merger be? How well/badly will KTE as the minority partner fair?

I just saw in another stock I used to hold that their recently announced SPP was cancelled due to market conditions moving the price well below the offer. Soon after the announcement of KTE's SPP the buy side filled up. Is that genuine interest, or artificial support for the SPP? Hard to say.

Either way the dearth of news regarding the results, or news regarding its obvious delay, is underwhelming to say the least.

To answer your last question: No, it's not abnormal to allow shareholders to buy different sized parcels of shares.
