MITSUI-SOKO LOGISTICS Expands Investment in T2 Inc.

MITSUI-SOKO LOGISTICS Co., Ltd. (Head Office: Chuo-ku, Tokyo; President: Teruo Ishikawa) is pleased to announce that we have further invested in T2 Inc. (Head Office: Chiyoda-ku, Tokyo; CEO: Masatomo Kumabe), which aims to commercialize trunk line transportation services using Level 4 self-driving trucks. We initially participated in T2's Series A funding round in August 2023, and this is our second investment.

Given the alignment between T2's vision for trunk line transportation using Level 4 self-driving trucks and our business strategy, we have maintained a robust collaborative partnership since our investment in the company in 2023. This partnership encompasses continuous support for joint proofs of concept on expressways and the development of an operational framework to commercialize the services.

As T2's business model becomes more established and approaches realization, we recognize the essential need to establish transfer hubs and relay stations to connect cargo to autonomous truck transport routes. Additionally, implementing efficient operations through labor-saving and automation strategies is crucial to fully leverage the capabilities of self-driving trucks. In this domain, we concluded that our additional investment would significantly strengthen synergies with T2. This decision is based on our evaluation that solutions leveraging the logistics expertise and robotics/digital technologies we have developed as an LLP* can be effectively implemented. Moreover, as a key business entity within the MITSUI-SOKO Group, we are well-positioned to deliver logistics solutions through collaboration with co-creation partners.

*LLP (lead logistics partner): A business model that supports supply chain management (SCM) and logistics at the planning and strategic levels.

Looking ahead, in alignment with the MITSUI-SOKO Group's Purpose-Empower society, encourage progress-we will enhance our business partnership with T2 through this additional investment. Together, we will persist in tackling challenges to develop a sustainable logistics infrastructure.
