You’re misinterpreting this. Every one of those previous batches of shares has been fully sold to the market. HCM had zero (0) shares before the issue shares, because all previously received shares have already been sold. They always sell all shares to the market immediately.
Now that they received quite a lot at once, it might take a moment, but I firmly believe that they will sell these too as quickly as they can. Their acquisition price, taking the subscription fee into account, is significantly lower than the current price, so they still make a profit by selling now.
