Tamura Corporation (Headquarters: Nerima-ku, Tokyo; President and COO: Mitsutaka Nakamura; hereinafter referred to as "the Company") will expand the production capacity of its subsidiary, Tamura Power Technologies de Mexico S.A. de C.V. (hereinafter referred to as "the Mexico Factory").　Although the Mexico Factory expanded its production capacity in both FY2023 and FY2024, the Company has decided to make an additional capital investment to meet continued strong demand. This investment is expected to drive a 3-fold increase in FY2027 sales of large transformers and reactors manufactured at the Mexico Factory, compared to FY2023.

(Total floor area: approx. 4,000 m², Additional capital expenditure: approx. US$2.7 million)

Large transformers and reactors are used in power conditioners for wind and solar power generation systems, DC power transmission and distribution, and power systems such as PDUs (Power Distribution Units) and UPSs (Uninterruptible Power Supplies).　The Company has established a global supply framework for large transformers and reactors, with eight production sites worldwide, originating from Europe. Currently, demand is growing rapidly, particularly in North America, driven by the expansion of data centers fueled by the rise of generative AI—especially for applications in PDUs and UPSs.
To meet this robust demand, the Company increased the production capacity of its Mexico Factory in FY2023, which manufactures large transformers and reactors for the North American market. In FY2024, a second plant was constructed nearby. With this latest initiative, additional production equipment will be installed at the second plant to further enhance capacity, and the Company is also considering further expansion in the future.

Under the 14th Medium-term Management Plan, "One TAMURA for Next 100," the Company has designated the clean energy-related markets—spanning power infrastructure, heavy industry, next-generation communications, and mobility—as key strategic focus areas. Among these, the data center market is one of the Company’s priority areas. In addition to large transformers and reactors, the Company offers a wide range of products that can be used in data centers, such as electronic chemical materials for servers and switchboards, current sensors and gate driver modules for UPSs, and transformers and reactors for HVAC (cooling systems).
By proposing total solutions through its diverse product portfolio, the Company aims to grow alongside the expanding data center market.
