ABC Tissue Products Pty Limited's major supplier, Hengan International Group Company Limited (SEHK:1044), is believed to be lining up to buy the business that is up for sale through Morgan Stanley. Sales documents are with prospective suitors for the business that may sell for up to $1 billion, and some are tipping Hengan will knock other parties out of the running. The other contender known to be eager to buy ABC Tissue has been Pacific Equity Partners, which has a strong track record of turning around manufacturing businesses. The challenge for PEP is likely to be that with Hengan as a contender, it is unlikely to be prepared to supply a rival acquirer of the operation.
