"Pro rata distribution from GREP Holdco III-B Holdings, LLC as well as Grey Rock"
A pro rata distribution is when a company or organization shares out money, assets, or benefits evenly among all eligible people based on their size or share. For example, if a company makes a profit and distributes it to shareholders, each person gets a portion proportional to how many shares they own. It ensures everyone gets their fair part based on their ownership or stake.
