Hitachi completes capital reorganization of air conditioning joint venture accelerating the deployment of green cooling solutions through “One Hitachi”

Tokyo, August 1, 2025 Hitachi, Ltd. (TSE:6501, “Hitachi”) and, its subsidiary, Hitachi Global Life Solutions, Inc. (“Hitachi GLS”), announced that they have completed the capital reorganization of their air conditioning joint venture, based on the agreement signed on July 23, 2024*1. Under this reorganization, Hitachi GLS transferred all of its shares in Johnson Controls-Hitachi Air Conditioning Holding (UK) Ltd. (“JCH”), a joint venture with Johnson Controls International plc (“JCI”), to Robert Bosch GmbH (“Bosch”)*2, and has completed the acquisition of the Shimizu Factory, which had been owned by JCH and served as its development and production base for commercial air conditioning equipment in Japan*3.

Going forward, Hitachi GLS will accelerate a global expansion of Hitachi-branded air conditioning products through Bosch Home Comfort Group (“Bosch HC”), Bosch's HVAC*4 business unit. Meanwhile, Hitachi will utilize its domain knowledge acquired through the Shimizu Factory to further strengthen its “Lumada 3.0” green cooling solutions through “One Hitachi” by combining the large installed base of HVAC units, AI, and digital capabilities to accelerate the expansion into growing markets such as green buildings and data centers. This will contribute to the realization of a harmonized society where environment, wellbeing, and economic growth are in balance, as envisioned in Inspire 2027, Hitachi Group's new management plan.

Aim of the Hitachi Group

1. Strengthening the Global Expansion of Hitachi-branded Air Conditioning Products, and an Expansion of the Partnership with Bosch

Under a brand license agreement with Bosch HC, Hitachi GLS will accelerate global expansion by utilizing Bosch's global footprint centered in Europe and promoting sales of highly-competitive, Hitachi-branded residential air conditioning products in the residential and light commercial HVAC markets in the US and Asia. Also, further expansion of the partnership with Bosch will be achieved by incorporating Lumada solutions in products.

2. Collaborating as One Hitachi to Accelerate the Deployment of Green Cooling Solutions in Growth Markets

With the acquisition of the Shimizu Factory, with its high technological capabilities, Hitachi GLS will integrate the development, manufacturing, sales, and maintenance services for the commercial air conditioning business in Japan to develop competitive products tailored to market needs. Also, Hitachi GLS will further enhance its Lumada solutions, such as “exiida*5”, which leverages data from the large installed-base of HVAC units and AI to support the stable operation of air-conditioning units.

Hitachi will expand green cooling solutions that combine its extensive installed base of mission-critical products with AI-enabled digital services as use cases of “HMAX for Industry” in growing industrial markets such as green buildings, biopharma, food, and semiconductor manufacturing facilities. In addition, Hitachi will accelerate the “One Hitachi” total solutions including air conditioning and cooling technologies in data centers, designated by the Strategic SIB*6 Business Unit as a strategic business area.

To ensure continued distribution of “Shirokumakun*7” series residential air conditioning products for the Japanese market, the Tochigi Factory*8 of JCH which was acquired by Bosch HC in the transaction, will retain development and manufacturing operations, while Hitachi GLS will remain responsible for sales and aftermarket services.

The purchase price of the 40% stake in JCH held by Hitachi GLS is approximately USD 1.46 billion (approximately JPY 211 billion*9). As a result, Hitachi plans to record business reorganization income, etc. of approximately JPY 154 billion as other income, etc. in its consolidated financial statements for the fiscal year ending March 2026. Please note that the final purchase price will be determined separately after accounting for all necessary adjustments. Hitachi will utilize the proceeds from this share transfer for its growth investments and shareholder returns, aiming to enhance its capital efficiency and further increase corporate value.
