A new investor brings money into the business to "purchase" those newly printed shares, so diluting previous investors' percentage of ownership doesn't necessarily change their material position unless there are more strings attached to the investment. For example, if an enterprise was worth $100M before investment and then there's a new investor that brings in $100M, the new investor owns 50% of a $200M pie and the previous investors combine to own 50% of $200M as opposed to 100% of $100M.
