KFC UK sales fell 9% in the first quarter, following widespread disruption caused by its supply chain problems.

Parent brand, Yum!, said that that KFC would have reported like-for-like sales growth of 3% in the UK without the shortage.

In its first quarter update, the group said that worldwide system sales excluding foreign currency translation grew 4%, with KFC at 6%, Taco Bell at 4% and Pizza Hut at 2%.

The group opened 239 net new units for 3% net new unit growth.

Chief executive Greg Creed said “As we begin the second full year of our transformation journey, I’m pleased with our progress towards becoming a more focused, more franchised and more efficient company.

“As a result of the timing mismatch between refranchising and associated G&A savings and the new revenue recognition accounting standard, core operating profit growth was flat, which is consistent with our expectations.

“We’re maintaining all aspects of our full-year 2018 guidance and remain confident that this transformation is building a strong foundation for long-term growth and will deliver increased returns for our stakeholders.”
