"Just given to LMB" as opposed to what?
The shares were already owned by LMB so just because they didn't sell the shares does not mean they need to buy them back.
You need to understand how this works. LMB now has a bigger slice of the caek without adding anything to the caek (which is arguably delicious).
If those shares were sold, (the extra private investors) + (LMB) would have gotten the same percentage of the profit that LMB is now getting, but *there would have been more money in the kitty.
