Total quality assurance provider Intertek Group saw its share price plummet by 18 per cent despite announcing a third consecutive year of double-digit growth.

London-headquartered Intertek operate a network of more than 1,000 laboratories and offices in more than 100 countries.

On Tuesday morning the FTSE 100 listed company provided its full year results for 2025.

Highlights included revenue growth up 4.3 per cent to £3,432m and profit before tax of £493.4m.

Intertek reported a third consecutive year of double digit adjusted EPS (Earnings Per Share) growth of 10.1 per cent at constant currency.

In terms of 2026, the company predicted ‘mid-single digit’ LFL (Like-for-Like) revenue growth, which may have spooked investors.

Intertek also completed a £350m share buyback programme.

The company’s share price closed a 3,980p.

CEO Andre Lacroix said: “Our 2025 results demonstrate, once again, Intertek’s ability to consistently deliver quality growth, improving its performance on a sustainable basis and delivering another year of record performance.

“I would like to recognise all my colleagues for having delivered a strong performance in 2025 in customer service, revenue growth, margin accretion, earnings growth, cash generation and ROIC.

“We have delivered a strong operating profit growth every quarter in 2025 resulting in a 10.1 per cent EPS growth at constant rates for the year and we are entering 2026 with confidence, targeting a strong performance with mid-single digit LFL revenue growth, continuous margin progression, strong earnings growth and strong cash generation.

“We are well positioned to seize the exciting growth opportunities ahead, given the continued increased investments of our 400,000 clients in risk-based quality assurance to operate with ever-higher quality, safety and sustainability standards in each part of their value chain, triggering greater demand for our solutions.”
