KELLOGG COMPANY REPORTS STRONG FOURTH-QUARTER 2011 RESULTS AND REAFFIRMS GUIDANCE FOR 2012

BATTLE CREEK, Mich. – Kellogg Company (NYSE: K) today announced that fourth quarter reported net sales increased to $3.0 billion, or by 5.4 percent from the fourth quarter of 2010. Internal net sales, which exclude the effects of foreign currency translation, increased by 6.0 percent over the same period. Fourth-quarter 2011 operating profit was $397 million, a reported increase of 20.3 percent; internal operating profit increased by 20.5 percent.

Full-year 2011 reported net sales increased to $13.2 billion, or by 6.5 percent from the $12.4 billion posted in 2010. Internal net sales increased by 4.5 percent over the same period. Reported full-year 2011 operating profit was $2.0 billion, a decline of 0.7 percent; internal operating profit, which excludes the effects of foreign currency translation, declined by 2.9 percent. This anticipated decline was the result of the company’s supply-chain initiatives, the reinstatement of incentive compensation costs, and continued high-levels of commodity inflation.

Full-year reported net earnings were $1.2 billion, or $3.38 per diluted share, an increase of 2.4% from full-year 2010 earnings of $3.30 per share. Full-year, currency-neutral 2011 earnings per share were unchanged from the previous year. Fourth quarter reported net earnings were $232 million, or $0.64 per diluted share, an increase of 25% from fourth quarter 2010 reported earnings of $0.51 per diluted share.

“In 2011 we started to build a foundation upon which we can grow,” said John Bryant, Kellogg Company’s president and chief executive officer. “We are pleased to have again posted very strong revenue growth and we have continued to make the investments necessary for future growth. Without the impact of the compensation costs and the supply-chain investment, our underlying operating profit increased in line with the company’s long-term target of mid single-digit growth. We will further improve our supply chain in 2012, but, as importantly, we will also focus our efforts on increasing investment in brand building and launching even stronger innovation.”

Latin America’s internal operating profit declined by 9.9% in the fourth quarter. Europe’s fourth-quarter internal operating profit decreased by 11.2% due to a continued difficult trading environment in the United Kingdom and higher input costs. Asia Pacific’s internal operating profit increased by 430.3% in the quarter driven by an impairment charge associated with our Chinese business that occurred in the fourth quarter of 2010. Without the impact of this charge, operating profit would have increased by approximately 50 percent.

Interest and Tax

Kellogg’s interest expense totaled $55 million in the fourth quarter, an improvement from the same quarter in 2010. The reported effective tax rate for the quarter was 32 percent; the tax rate for the full year was 29 percent.

Cash flow

Kellogg Reaffirms 2012 Earnings Guidance

The Company reaffirmed its guidance for internal net sales growth, which is expected to increase by 4 to 5 percent, greater than long-term annual targets and reflecting both improvement in price/mix and a stronger innovation pipeline. Kellogg expects full-year operating profit to be unchanged or slightly greater as the company continues to invest in future growth. Full-year, currency-neutral earnings per share are anticipated to grow between 2% and 4% including the impact of continued investments in supply chain, an update of the company’s SAP platform, an increase in the level of investment in brand building, and a benefit from the three-year $2.5 billion share repurchase program.

Bryant continued, “We remain very pleased with our revenue growth and the underlying strength of our businesses. We participate in attractive categories and our brand-building and innovation programs are strong. While we recognize that 2011 and 2012 are transition years, we are confident that we are making the right investments in the company, and in future growth.”
