Shares in Mobico, the former National Express, plummeted after the company reported disappointing financial results and announced the resignation of its chief financial officer. The group saw a 36% drop in pre-tax profits to £92.9 million due to accountancy issues in its German railway division that delayed annual results twice. Despite revenue growth, CEO Ignacio Garat acknowledged that the results fell short of expectations and hinted at further fare increases. The company expects an uptick in earnings for 2024 but foreshadowed potential restructuring and downsizing in its struggling private coach hire business, National Express Transport Solutions.
