After a little time to reflect on Zenn's recent round of investment in EESTOR, I believe I have a very plausible explantion for KP's not buying in. They cut a deal with KP.
That deal is that Zenn has agreed to sell EESU's to Think! and Fiskar, and possibly KP's unnamed electric car company, in return for KP not buying in and reducing Zenn's stake. Without EESU's Think! and Fiskar would be toast and KP would be out 10's of millions. This deal preserves that investment.
It is a win-win for both Zenn and KP.
So, would Zenn be required to disclose such an agreement? No, not even under the more stringent US reporting requirements since it is not a "material definitive agreement". It doesn't fit the definition of "material" yet since there is no purchase commitment. But it could be an agreement to sell, if and when that day comes.
Another much more speculative reason might be that there are additional rights that KP might have been entitled to if their investment had increased and DW mght not have wanted that to happen. A big, big maybe on this one, as far as being an additional motivation.
