In line with Belgian transparency legislation (Law of May 2, 2007), UBS Group AG recently sent to Solvay the following transparency notification indicating that they crossed the threshold of 3%.

The notification, dated September 24, 2024, contains the following information:

• Date on which the threshold is crossed: September 18, 2024
• Threshold of direct voting rights crossed: 3% downwards
• Denominator: 105,876,416
• Additional information: The disclosure obligation arose due to the total indirect holdings of UBS Group AG in voting rights of Solvay SA, held directly by controlled undertakings falling below 3% on 18 September 2024.
