Bridgestone has signed a definitive agreement to sell Mexico Carbon Manufacturing S.A. de C.V. (MXCB) its reinforcing carbon black facility in Altamira, Mexico to Cabot Corporation for US $70 million, debt-free and cash-free. The transaction includes a long-term supply relationship, awaits regulatory approval in Mexico, and is expected to close within 3–6 months; the plant was commissioned in 2005, adjacent to Cabot’s existing Altamira site.

TOKYO (August 5, 2025) - Bridgestone Corporation (“Bridgestone”) announced that it has entered into an agreement to sell its group company, Mexico Carbon Manufacturing S.A. de C.V. (“MXCB”) to Cabot Corporation (“Cabot”).

Bridgestone is committed to reinforcing its global business quality by “turning changes into opportunities” in today’s volatile business environment. The company is accelerating the establishment of a foundation for “growth with quality.” In its premium tire business, Bridgestone is aiming to improve productivity and creativity across the entire value chain, from material and tire development, raw material procurement and production to logistics and sales, with a focus on enhancing its “Dan-Totsu products.” The sale of MXCB is part of these strategic initiatives.

Bridgestone is rebuilding its in-house carbon black business in areas where it can leverage collaboration with global partners such as Cabot who have specialized knowledge, networks, and resources. The relationship between Cabot and Bridgestone dates back to the 1950s, during which a long-term relationship of trust has been established. Cabot, a leading global supplier of carbon black with a strong global footprint, is a global partner with a proven track record of delivering high-quality, reliable supply. With this business transfer, Bridgestone aims to respond to changes in the business environment and strengthen its competitiveness over the mid-to-long term by leveraging Cabot’s supply system, technologies, and extensive knowledge related to carbon black further. Bridgestone will also continue to advance the development of a sustainable supply chain to create further social and customer value, together with global partners.

Bridgestone will continue to develop and produce strategic carbon black in-house in areas that are directly linked to its core competence – material technologies, or “mastering rubber” – and where proprietary knowledge and technologies are essential. These areas include premium tires, motorsports tires, and sustainability. These operations will be carried out through Asahi Carbon Co., Ltd., Bridgestone’s group company in Japan. By maintaining in-house development and production of strategic carbon black, Bridgestone will ensure alignment with its business and product strategies and strengthen its “Dan-Totsu” products throughout the value chain. Through these

efforts, the company aims to further enhance its competitive advantage and accelerate value creation.

This transaction is part of business restructuring and rebuilding (2nd Stage) in Bridgestone’s Mid-Term Business Plan (2024-2026).

The impact of this transaction on the consolidated financial forecast for the current fiscal year is minimal.
