Revised Outlook - Hog Production Segment

On July 18, 2012, the Company provided the following updated outlook with respect to its Hog Production segment.

The section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Outlook,” beginning on page 32 of the Company’s Annual Report on Form 10-K for the fiscal year ended April 29, 2012, is updated as follows with respect to the Hog Production segment. The outlook for our other segments remains materially unchanged from the discussion in our Annual Report on Form 10-K for the fiscal year ended April 29, 2012.

Hog Production

Recent concerns about drought conditions in the United States have caused sharp increases in feed grain prices. However, we expect hedge positions placed prior to the run-up in grain prices will mitigate, to a meaningful extent, the negative impact on our raising costs. In fiscal 2013, we now expect raising costs to average in the mid $60s per hundredweight throughout the fiscal year, as the blended effect of hedge gains and higher spot corn prices are averaged into cost over the course of the year.

Notwithstanding concerns about U.S. drought conditions, we believe a balance domestically, between restrained supply of pork and other proteins, coupled with healthy exports, is supportive of modest hog production profitability going forward. We expect marginal profitability in the Hog Production segment for the full fiscal year, with operating margins for fiscal 2013 below our normalized range of $10-$15 per head. While the current futures strip does not yet support these profitability levels, the relative health of U.S. pork fundamentals, existing risk management positions, and relatively high hog prices provide the basis for our outlook for the full fiscal year.
