Imperial Suspends Quarterly Dividend and Winds Up Mexican Marketing JV

SUGAR LAND, Texas—November 3, 2011—Imperial Sugar Company (NASDAQ:IPSU) announced that its Board of Directors suspended payment of its regular quarterly dividend of $0.02 per common share until further notice in light of the continued pressure on its gross margins and liquidity primarily caused by sustained high raw sugar prices and competitive refined sugar pricing. The company indicated that borrowings under its revolving credit agreement totaled $81.5 million at fiscal year end September 30, 2011, resulting in available undrawn borrowing capacity of $44.0 million subject to the terms of the credit agreement.

The company also announced that in October, it sold its 50% joint venture interest in Comercializadora Santos Imperial, S. de R.L. de C.V. to Ingenios Santos, its partner in the joint venture for $5.5 million in cash. As part of the wind up of the CSI joint venture, the parties terminated all cross-border exclusive supply agreements, and entered into a non-exclusive two year agreement for supply of refined sugar to Imperial from Santos’ mills. John Sheptor, Imperial’s President and CEO commented, “We are very pleased with the strategic value our CSI venture provided in the early period of full NAFTA implementation. As the post-NAFTA Mexican/US sugar industry has developed, we concluded that a non-exclusive relationship was in our best interest. We have highest regard for the Santos organization and look forward to continuing a mutually beneficial business relationship in the coming years.”

The Company said that it continues to pursue its previously announced review of strategic alternatives for its 50% interest in Wholesome Sweeteners, including the potential sale of Wholesome.
