BP Castrol K.K.

There have been no material changes to the business activities conducted by our Group during the current interim accounting period. We identified the stable supply of lubricating oil products as our top priority. By leveraging our global and domestic procurement networks, we worked to secure a stable supply of raw materials and reduce supply risks, while maintaining inventory management based on supply and demand trends and supply systems for key customers. In terms of earnings, we partially absorbed cost increases resulting from higher raw material and logistics costs and foreign exchange fluctuations by strengthening cost management and promoting appropriate sales pricing. We also worked to expand sales opportunities through brand marketing initiatives and the use of digital channels. In addition, we promoted measures to improve operational efficiency, including digital transformation, to enhance the efficiency of business operations and strengthen our business foundation. As announced in the notice dated 26 December 2025 regarding the planned change in the parent company, we will promptly disclose any material matters requiring public disclosure that arise in connection with the transaction under which the bp Group will transfer its Castrol business to Stonepeak, subject to regulatory approvals and other conditions.
