BASF SE is making this notification on behalf of itself and on behalf of its wholly owned subsidiary BASF Handels und Exportgesellschaft mit beschränkter Haftung.
BASF SE and BASF Handels und Exportgesellschaft mit beschränkter Haftung ("BASF") hold the shares in Harbour Energy plc ("Harbour") indirectly via a custodian, Vidacos Nominees Limited (as described in section 9 above), which holds the legal title to those shares on their behalf pursuant to a custody arrangement.
BASF entered into an agreement on 17 May 2026 to dispose of 150 million ordinary shares in Harbour to Altor Finance Limited, an entity sharing common ultimate ownership with BW Group (the "Transaction"). Closing and settlement of the Transaction is expected to occur on or before 26 May 2026. To enable the Transaction triggering this notification, Morgan Stanley Europe SE has agreed to waive the 90-day lock-up governing any sale of shares in Harbour by BASF, which was imposed following closing of the secondary placing of shares in Harbour shares by BASF on March 31, 2026 [(the "Placing"), solely in respect of the Transaction. The voting rights which BASF is disposing of (as disclosed in this notification) will remain subject to lock-up restrictions for the balance of that 90-day period. BASF's remaining voting rights in Harbour continue to be subject to the balance of the 90-day lock-up restrictions detailed in the Placing announcement dated 27 March 2026.
