Ann: Annual Report to shareholders, page-71

It will be a new IPO.

From my understanding they had cash left over after an oil price crash a while ago. They were then actively looking for an energy based investments other than oil. Someone brought the two together, as Mears needed capital to test their solar technology, plus they wanted to go public. A reverse takeover of KTE was proposed but failed to raise the required capital.

All of a sudden, tech is now popular and Mears raised $14m. It's going public next year.

That's the story so far, weather this will happen is anyone's guess.
