ADP shares fall 4% as France proposes higher transport infrastructure tax
Aeroports de Paris (ADP) shares dropped 4.4% before recovering to a 1.1% loss after France proposed raising the TEITLD tax on transport infrastructure to 12.2% from 4.6%, aiming to generate €800M more annually. The tax impacts airport operators more than motorway companies, as airports can pass costs to customers. The revenue will fund transport infrastructure maintenance and modernization.
