(MarketWatch) — Foster’s Group Ltd. earlier this month revealed that it received an offer for its wine business but investors on the hunt for an acquisition-related upside should be wary about the potential for deal-related disappointment, analysts say. The Australian brewing firm said on Sept. 7 that it rejected an approach for the unit, which media reports had tied to U.S. private-equity firm Cerberus Capital. Other suitors for the unit could include Kohlberg Kravis Roberts and TPG, which have been talking about launching a joint bid according to reports Monday.
