Liverpool owners Fenway Sports Group (FSG) have sold a minority stake in the club to global sports investment firm Dynasty Equity.
The deal is worth between £82 million and £164 million, ending the search for new investment by FSG, who wanted to retain majority ownership of the club.
The new investment will primarily be used to pay off the club's bank debt incurred during the pandemic.
It is also designed to raise cash for the enhancements to Anfield Stadium, building the AXA Training Centre, repurchasing Melwood training ground for the women's team and acquisitions during this summer's transfer window.
"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.
"We look forward to building upon the long-standing relationship with Dynasty to further strengthen the club's financial position and sustain our ambitions for continued success on and off the pitch."
