Liverpool owners Fenway Sports Group (FSG) have agreed to sell a minority stake in the club worth between £82m and £164m to global sports investment firm Dynasty Equity.
The deal ends the search for new investment by FSG, who wanted to retain majority ownership of the Reds.
The new investment will primarily be used to pay off the club's bank debt.
"Our long-term commitment to Liverpool remains as strong as ever," said FSG president Mike Gordon.
"We have always said that if there is an investment partner that is right for Liverpool then we would pursue the opportunity to help ensure the club's long-term financial resiliency and future growth.
