Shala Doesn't have a website. Shala is a simply a shpk set up to house the concessions which Lluka's Dukagjini along with its Slovenian partners INTERENERGO, control. There is no need for them to have a website, as its a private company that currently is just a concession holder. Shala is registered in the National Registration Center in Albania with NIPT (Identification Number) K92118003C, having its headquarters at: Blv "Deshmoret e Kombit", Twin Towers, Kulla 2,11/2, Tirana, Albania.
Yes the info is in a 10k. Don't have the link with me right now.
As for Rudana, yes they filed for bankruptcy years ago. We all knew this. $4b likely was never invested by them, at least there is no evidence that it had been.
