Ireland is raising the financial thresholds for mandatory merger control notifications from July 2026, increasing the combined Irish turnover requirement from €60 million to €100 million and the individual turnover threshold from €10 million to €15 million. This change follows recommendations from the Competition and Consumer Protection Commission and a public consultation process, with significant implications for transaction notification requirements and regulatory oversight.

  • €100 million combined Irish turnover (up from €60 million); and
  • €15 million individual Irish turnover by at least 2 parties (up from €10 million).

  • 2025: The Irish national competition authority, the Competition and Consumer Protection Commission, made a recommendation to increase the financial thresholds for mandatory notification.
  • 23 March 2026: The Irish Department of Enterprise, Tourism and Employment (Department) published a public consultation on raising the financial thresholds.
  • 10 June 2026: Department announced change from1 July 2026.

What’s the Impact?

  • Likely reduction in the number of mandatorily notifiable transactions – more likely to exclude domestic than global deals.
  • Likely increase in the exercise of call-in powers & voluntary notifications of below threshold transactions.
