Port Vale will receive an initial £5million investment from Blue Sky International over the next 12 months.
An expected additional commitment of £2.5million over the next five years will be used for significant community outreach facilities throughout the Stoke-on-Trent area.
The total investment from the American sports construction firm into the club will reach £8million thanks to the further £500,000 the club will receive to spend on pre-season tours for the next 10 years.
Port Vale chairman Mike Lloyd told the club's official website: "We welcome such a substantial investment which will further strengthen the unifying of the club and fans following difficult times."
CEO Perry Deakin added: "This is a fabulous agreement for the football club and secures our long-term future."
