Epic Group is considering a stake sale to help boost growth as investors increasingly eye opportunities in Hong Kong, according to people familiar with the matter.

The apparel manufacturer is working with BDA Partners Inc and Goldman Sachs Group Inc on a review, the people said, asking not to be identified because the information is private. Epic might be valued at more than $500 million in a deal, they said.

Private equity firms and other textile companies have shown preliminary interest in the closely held business, the people said. Deliberations are at an early stage and no final decisions have been made, they said, adding that the end result might be a minority or majority stake sale.

Epic and BDA didn’t respond to requests for comment. Goldman Sachs declined to comment.

Hong Kong-based companies have been striking deals as global investors seek to deploy capital in the Asian financial hub. Examples include Warburg Pincus agreeing to invest in corporate services provider Acclime, and FountainVest Partners and CPE investing in RFID and brand identification firm SML Group Ltd.

Epic expanded from a textile trading house to fabric supplier and garment maker with facilities in Bangladesh, Jordan and Ethiopia, according to its website. Founder and Chairman Ranjan Mahtani established Epic in the early 1980s after a business trip to Bangladesh.

Epic’s customers include Levi Strauss & Co, Fast Retailing Co’s Uniqlo, Walmart Inc, Amazon.com Inc and other retailers and banks such as HSBC Holdings Plc.
