I am not clear where you are getting “will increase Makonis share by half of Nuvola shares”.
If you mean the share price, then it is not increasing by half.
If you mean the number of shares, then the question says that they will be issuing one Makonis share for every two Nuvola shares. So the number of shares goes up by half of the number of Nuvola shares (but this is the same whatever the premium is).
