French concessions and construction group Vinci on Friday reported a jump in its half-year core profit, boosted by positive energy transition trends and recovering traffic at its airports.

The company, which operates highways and airports like London's Gatwick, said its earnings before interest, tax, depreciation and amortisation (EBITDA) rose 17.3% to 5.31 billion euros ($5.83 billion) in the first six months of 2023, compared to a year earlier.
