From the major shareholder notification, it appears that the notification is made as a result of delivery of the estate after Gustav Kähler on 5 April 2018 to Birte Svare Kähler as an undivided estate (in Danish: uskiftet bo).

• the estate after Gustav Kähler has divested (a) 1,128,006 A shares (DK0010219070) (5.13 % of the total share capital) of nominally DKK 10 per share corresponding to 11,280,060 voting rights (9.17 % of the total voting rights), and (b) 184,088 B shares (DK0010219153) (0.84 % of the total share capital) of nominally DKK 10 per share corresponding to 184,088 voting rights (0.15 % of the total voting rights), following which Gustav Kähler no longer owns shares in ROCKWOOL International A/S, and that

  - Birte Svare Kähler as undivided estate has acquired (a) 1,128,006 A shares (DK0010219070) (5.13 % of the total share capital) of nominally DKK 10 per share corresponding to 11,280,060 voting rights (9.17 % of the total voting rights), and (b) 184,088 B shares (DK0010219153) (0.84 % of the total share capital) of nominally DKK 10 per share corresponding to 184,088 voting rights (0.15 % of the total voting rights).
