He said, in the company's annual report, that the commodities cycle was driving strong sample flows in its geochemistry division in particular.

"The long-term structural drivers of our key markets remain strong with our diverse portfolio of 350 operations in 65 countries well-positioned to capture growth opportunities," he said.

Naran said while the COVID-19 pandemic continued across the globe, there still remained the potential for economic disruption that might impact ALS.

"The swift actions of our management team prepared the company for the onset of the pandemic with the group now in a strong position to capitalise on growth opportunities arising from an improvement in trading conditions," he said.

"We maintain our commitment to quality and service that has supported our clients through this challenging time."

At the beginning of the pandemic the ALS cost base was rapidly aligned with client demand and all non-essential spending was ceased as the business focused on cash conversation and balance sheet strength.

"Capital expenditure was maintained in key areas where growth opportunities remained, which allowed the group to benefit from improving trading conditions in the second half of the year," Naran said.
