Some interesting information I found today. Recently, large cap Canadian company Vermillion Energy purchased almost 600,000 acres of natural gas leases in Eastern Ukraine, right in the same region as Cub Energy: https://www.newswire.ca/news-releases/vermilion-energy-inc-announces-results-for-the-three-and-six-months-ended-june-30-2019-816869944.html

Then I also saw on Vermillion Energy's website that they are partnerd in Slovakia with NAFTA, the same partner KUB has right now, drilling the JV wells in the West.

In Slovakia, we have partnered with NAFTA, the country's dominant E&P in a farm-in arrangement which grants us a 50% working interest to jointly explore 490,000 acres across two licenses. In Ukraine, we have been awarded two exploration licenses in a 50/50 partnership with Ukrgazvydobuvannya ("UGV“), a Ukrainian state owned gas producer: https://www.vermilionenergy.com/our-operations/europe/central-eastern-europe.cfm

The point here is that Vermillion is likely to buy Cub Energy down the road for their production and large lease holdings.
