Reduction of the share capital

Group 1 - The Annual General Meeting of ROCKWOOL A/S resolved to reduce the Company's B share capital from nominally 118,028,700 DKK to nominally 113,427,400 DKK by cancelling a portion of the Company's treasury B shares, amounting to 4,601,300 DKK [1] - The capital reduction has been completed and registered with the Danish Business Authority, resulting in the cancellation of 4,601,300 B shares of 1 DKK each, leading to a total share capital of nominally 211,605,790 DKK, which includes a class A share capital of nominally 98,178,390 DKK and a class B share capital of nominally 113,427,400 DKK [2] - The capital reduction does not impact the Company's share buy-back programme, which will continue as previously announced [3]
