Tune in to hear how these differences shape competition enforcement—and why they matter for clients, courts, and the future of antitrust.

In June 2025, the European Commission announced a decision under which it fined two competing online food delivery companies a combined total of €329 million for cartel behaviour that took place while one company held a minority stake in the other company. The infringing behaviour included, among other things, exchanging competitively sensitive information “beyond what was needed for a corporate investor to protect a financial investment decision.” Does the Delivery Hero/Glovo decision suggest that minority shareholdings may be subject to stricter scrutiny going forward? Hosts Matthew Hall and Alicia Downey talk to Brussels-based competition lawyer Peter Camesasca about what the decision means and its practical implications for compliance counseling.
