BATTLE CREEK, Mich., May 2, 2013 (GLOBE NEWSWIRE) -- Kellogg Company (NYSE:K) today announced solid results that were in-line with the company's expectations. First quarter 2013 reported net sales increased by 12.2 percent to $3.9 billion. Internal net sales*, which exclude the effects of foreign currency translation, acquisitions, dispositions, and integration costs, rose by 2.2 percent over the same period. First quarter 2013 operating profit was $503 million, a reported decrease of 4.5 percent; underlying internal operating profit*, which excludes the effects of foreign currency translation, acquisitions, dispositions, mark-to-market accounting, and integration costs, decreased by 5.8 percent. As expected, the decline in underlying internal operating profit* was largely due to the recognition of considerable cost-of-goods-sold inflation in the quarter. Results in the first quarter included a majority of the inflation, net of cost savings, that the company expects to recognize for the full year. Reported earnings for the first quarter 2013 were $311 million, or $0.85 per diluted share, a decline of 13 percent from the $0.98 per diluted share reported in the first quarter of last year. Comparable first quarter 2013 earnings*, which exclude the impact of mark-to-market accounting and integration costs associated with the acquisition of Pringles, were $0.99 per share, in-line with the company's expectations. This result included a negative impact of $0.03 per share from the Venezuelan devaluation. "Results in the first quarter were broadly as we expected, and we're pleased to have a solid start to the year," said John Bryant, Kellogg Company's president and chief executive officer. "We saw good comparable revenue growth in many regions around the world and the Pringles business continued to post strong results. As a result, we're also pleased to report that we're on-track to meet our guidance for the full-year." * Internal sales growth, underlying internal operating profit growth, underlying internal operating profit, and comparable earnings are all non-GAAP financial measures.
