"We are reaffirming our full-year earnings guidance on a currency-neutral basis," said John Bryant, Kellogg Company's president and chief executive officer. "While sales growth has been slower than we anticipated in developed markets, particularly the U.S., the work we have been doing on our cost base has enabled us to offset the impact. In addition, we have now owned Pringles for more than a year. The integration has gone very well, and we remain excited regarding the opportunities we see for future growth."
