COPENHAGEN: Shipping group Maersk said on Tuesday operating profit for the first quarter and guidance for the full year were above its previous expectations, driven by high container freight rates. Revenue in the first three months of the year stood at $19.3 billion, with underlying earnings before interest, tax, depreciation and amortization (EBITDA) at $9.2 billion. Guidance for the full year was revised upwards, with underlying EBITDA expected to be about $30 billion compared to $24 billion previously expected.
