A group of shareholder firms retaining 6.8%of Di Giorgio Corp.’s shares said in an SEC filing that they will urge Gabelli partners to raise their $238-million bid for the San Francisco company. The Gabelli partnerships offered to buy Di Giorgio, a food processing, building products and real estate company, for $28 per share cash on June 25. The partnerships making the offer include Gabelli/Rosenthal & Partners and G&R; Partners. If the Gabelli partners are unwilling to make a higher offer, the shareholder group, which is led by London-based Mim Ltd., said it will attempt to replace Di Giorgio’s board with one which will adopt policies geared to increasing the value of the company’s stock.
