Investopedia explains 'Primary Distribution'
A "secondary distribution" is the opposite of a primary distribution and refers to an occurrence where an existing shareholder sells a block of previously-issued stock and takes the proceeds from the sale. A company only receives funds for a primary distribution, or IPO; the stock continues to trade after the initial offering, but the funds are exchanged between buyers and sellers.
