Experian PLC (LSE:EXPN) shares fell over 6% to lead the FTSE 100 fallers on Thursday as the credit checking giant reported slower growth in North America.
Full-year guidance was kept unchanged after total first-quarter revenue grew 10% in the three months to 30 June, or 8% at constant exchange rates and 7% on an organic growth basis.
North America, which accounts for around two-thirds of group revenue, delivered 7% organic growth, driven by demand for fraud prevention products, analytics software and mortgage-related services. This was a slowdown from the 10% organic growth in North America seen last year.
Consumer services revenue in the region fell 2% following the planned wind-down of two large data breach support contracts, although the business grew 3% excluding that impact.
Latin America remained the fastest-growing region, with organic revenue up 12%, helped by new business wins in Brazil and continued strength in fraud prevention.
UK and Irish revenue increased 5%, supported by new customer wins and growth in the Ascend Platform.
Chief executive Brian Cassin said: "Our full-year expectations are unchanged. We continue to execute well, supported by our trusted data assets, scaled platforms and growing AI-enabled opportunities."
Broker Panmure Liberum said North American organic growth slowed due to a 2% decline in consumer turnover due to the run off of large data breach contracts, which had been previously flagged, and softer underlying growth of 3%.
The UK was better and EMEA/Asia Pac worse than expected, analysts added.
