The company, which also makes pharmaceuticals and specialty chemicals, on May 4 reported better-than-expected quarterly earnings for the group ahead of schedule.
At the time it said it expected 2021 adjusted earnings before interest, tax, depreciation and amortization (EBITDA) of 5.4-5.8 billion euros, up from 5.2 billion last year. It reaffirmed that guidance on Wednesday.
