The company posted adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) of over 1 billion euros ($1.11 billion) last year while group adjusted net profit rose 6% to 367.7 million euros.
The company said it would propose the distribution of a 0.295 euros dividend per share, 6.5% higher compared to that of the previous year.
