Not much difference between listed and private for holders, either way without a confirmed tower deal the company is worthless. Possibly easier to sell your shares if they stay listed and trade but without a tower who is going to buy so you can sell. If they delist and go private you can still sell but again you need a buyer.
The only real chance is for a tower deal to materialise. If that happens then they will trade again for sure and holders can decide in or out.
Possibility the company could fold here and function as a private company in the US. US being where the money is and where the risk of being first is not a inpenatrable wall like it can be here. China could also pull a rabbit out of a hat but it would be state built.
All speculation on on my part but don’t see anything positive at this point. Even if a tower deal was announced today the track record of announcing deals and then seeing all of them fall over will still haunt EVM and unlikely to shift the SP in a positive direction until complete funding, site approvals, planning approvals, construction approvals and so on all get signed off and the bulldozers move in.
as far as getting a resolution for KPi, it can be done if you get enough support from other holders large enough to out vote those that may oppose it. Not impossible to do but lots of time and effort required.
