It is not a national gas company. It is a gas company with 3.2% of the production share in Ukraine. You should always check these things so you don’t fall for Russian lies.
I have done the work so I can share it with you.

They are producing 10.4k boe per day. I use 170 to convert it to cube meters. 10400*170*365=0.645 billion. Ukrainian gas production is ~20 billion per year. 0.645/20*100 = 3.2%
Company with 3.2% production share sounds much less impressive than “National Gas Company”.
This is where the 170 comes from: http://en.wikipedia.org/wiki/Barrel_of_oil_equivalent
Well I’m sure Hunter Biden will be happy to know he has a friend at FR.
