In March 2021, Marubeni Corporation (hereinafter, "Marubeni") invested in Skeleton Technologies Group OÜ (hereinafter, "Skeleton") in Estonia, which develops and manufactures ultracapacitors (hereinafter the "Investment"). Marubeni will start to work on sales of Skeleton's ultracapacitors and develop the use cases and markets of its next generation energy storage technology with Skeleton in Japan and other Asian countries.

In the global fight against climate change, in October 2020, Japan's Prime Minister declared the country will become "Carbon Neutral by 2050". The Japanese government promotes its green growth strategy aiming to create a balanced economic and environmental circle through transforming the industrial structure and social economy, strengthening decarbonization efforts, and developing and implementing innovative technologies. As such, energy storage technologies are expected to be applied to a broader range of areas, such as stabilizing the power supply from renewable energy to power grid, acting as a power source for electric vehicles, and being combined with hydrogen generation application or fuel cell systems.

Ultracapacitors are used as energy storage devices in various industries including automotive, transportation, construction machinery, electric power, and industrial machinery. Their unique and superior features, such as high-power density, high-speed charge/discharge, long life, safety, and recyclability, make them especially attractive. Skeleton, as the largest ultracapacitor manufacturer in Europe with its research and development facilities in Estonia and Germany and its manufacturing facility in Germany, currently supplies its ultracapacitor products, with the highest performance level in the market, to clients such as major automotive manufacturers and global electrical & power generation system manufacturers in Europe and the United States. Furthermore, Skeleton is developing next generation products that will have a significant increase in energy density, which will enable them to be applied to a wider range of areas, achieve more efficient energy usage at a lower cost, and provide environmental protection measures by being an alternative to lithium-ion batteries and lead-acid batteries, or by being combined with fuel cell systems.

Through the Investment, Marubeni, as a strategic partner of Skeleton, will leverage its global marketing capabilities to carry out the sales of Skeleton's ultracapacitors in Japan and other Asian countries, and will develop the applications of its next generation products utilizing its relationship with existing clients in various industries. Marubeni will contribute to the achievement of a decarbonized society－a globally shared goal－and the realization of a sustainable society by enabling the creation of new business models that capture the growing demands of society, such as Smart City, decentralized and renewable new energy solutions, and autonomous vehicles.
