before the last reverse split ca. 309 mm shares were outstanding. RS happened in August '20 ( 1: 1000 ) so, after that 309 k shares were outstanding. Thereafter a capital increase took place. New number ca. 304 mm.
So, the max freeflote thereafter sould have been about 1 per mille.
Probably even less than that, as Eurogas Inc might have collected freefloat shares before the RS.
