Sportswear brand Castore is in talks with investors over a $200m cash injection, according to reports over the weekend.
The Manchester-headquartered company is working with Rothschild to secure the extra funding, Sky News has said.
The business was founded by Liverpudlian brothers Phil and Tom Beahon and counts the likes of Andy Murray and the billionaire Issa brothers, who own Asda, among its shareholders.
