PowerX,Inc., H1 2026 Earnings Call, Aug 13, 2026

PowerX Inc. announces that it has unveiled the "Mega Power 4000" series, a new lineup of high-capacity battery energy storage systems (BESS) in 20-foot containers, designed to meet the growing scale of grid battery farms and to compete in global markets. The series comprises two models with storage capacities of 4.6 MWh and 4.2 MWh, depending on the battery cells used, with mass production scheduled to begin in May 2027. As renewable energy adoption accelerates worldwide, utility-scale battery energy storage projects continue to grow in scale. In Japan, the average size of successful BESS bids in the Long-Term Decarbonization Power Source Auction*1 expanded from 36 MW in Fiscal Year 2023 to 66 MW in Fiscal Year 2025, and the share of large projects of 75 MW or more rose from 3% to 37%*2. In such large projects, the number of BESS units and the scale of on-site construction significantly affect overall project costs, driving demand for greater capacity per container. To meet these customer needs, the Company developed the "Mega Power 4000" series, which features a high-density design incorporating liquid-cooled lithium iron phosphate (LFP) batteries in a 20-foot container. The Company positions the series as its global strategic model and has begun making proposals to customers in Japan and overseas, aiming for full-scale expansion into markets such as Australia and Southeast Asia. The Company will offer a standard package combining the new BESS with "Grid Connector for BESS," a grid interconnection system also announced today that integrates power conditioning systems (PCS), transformers, and high-voltage switchgear, as its core solution for large-scale battery power plants in Japan and overseas. By optimizing BESS and grid interconnection equipment as a fully integrated solution, the Company will reduce construction costs and shorten the time to commercial operation. Through these efforts, the Company aims to differentiate its storage solutions and strengthen its competitiveness. Key features of the "Mega Power 4000" series are as follows. Each unit offers a storage capacity of up to 4,680 kWh, approximately 1.7 times the capacity of the Company's existing product of the same footprint. For a battery farm of comparable scale, this reduces the number of battery containers required by roughly 40%, reducing construction costs associated with foundations, wiring, installation, and on-site commissioning, while also shortening construction timelines. In addition, this is the first product of the Company designed to support double-stack installation of battery containers. When double-stacked, up to 9,360 kWh can be installed per 20-foot container footprint (approximately 14.8 m²), approximately 3.4 times the storage capacity of the Company's existing product, enabling more effective use of land.

PowerX Inc. had introduced the “Grid Connector” series, a new product line of integrated grid connection systems for utility-scale battery storage projects and data centers. Factory-integrated into skid-mounted units, each system combines a power conditioning system (PCS), transformers, high-voltage switchgear, and other components, reducing on-site work primarily to installation and connections and helping bring facilities online sooner. Through the adoption of the Company’s newly developed in-house PCS and optimization of the overall system, the Grid Connector series significantly lowers deployment costs, while its integrated control and communication design strengthens cybersecurity. By developing the overall architecture in-house, the Company has further improved ease of installation and compatibility with its own battery energy storage systems (BESS). The first product in the series is the “Grid Connector for BESS,” designed for battery farms. As an extension of the series, the Company also announces the “Grid Connector for DC” for AI data centers. The Grid Connector for BESS is a high-efficiency, all-in-one grid interconnection solution featuring silicon carbide (SiC) power modules. Two models will be offered: a 2.5 MVA model packaged in a single 20-foot-container-sized unit and a 5 MVA model consisting of two units. The product offers high compatibility, in terms of both hardware and software, with the Company’s large-scale BESS products in the “Mega Power” series. When deploying a utility-scale BESS project with the “Mega Power 2500,” up to eight battery containers can be connected to a single “Grid Connector.” This not only increases flexibility in site footprint and layout, but also minimizes on-site system integration and simplifies installation work. The product also features the Company’s newly developed in-house PCS. Compared with the externally procured PCS used previously, the newly developed PCS lowers costs. By optimizing the entire system, including transformers and high-voltage switchgear, it also helps reduce the initial deployment cost of battery farms. The PCS will also be available on a standalone basis, in addition to being offered as part of the integrated “Grid Connector.” Prototyping and validation of the Grid Connector for BESS will begin at the end of this year, with mass production and market rollout starting sequentially from Third Quarter of 2027. This product applies the grid interconnection technologies developed for battery farms to AI data centers. It simplifies and accelerates the construction and grid connection of AI data centers, where power consumption and heat generation continue to grow. The equipment required to launch a megawatt-class GPU data center is consolidated into the following function-specific units: Power Unit: substation equipment housing a SiC-based PCS, transformers, and other components; Battery Unit: built around the “Mega Power 2500,” a 10-foot-container-sized BESS; Cooling Unit: equipped with chillers and coolers that supply the cooling water essential to data centers. The factory-integrated modular design enables the Company’s “Zero-Day Connection” concept, while redundant power and cooling provide the reliability required of the latest AI data centers. By integrating power, storage, and cooling equipment and centralizing the control and communication specifications and access management of each unit, the product reduces cybersecurity risks compared with configurations in which multiple systems are connected and managed independently. In addition, because a large-capacity battery is included as standard, ancillary equipment such as UPS (uninterruptible power supply) systems can be simplified in some configurations, supporting business continuity planning (BCP). For the data center product, a prototype will be installed in early 2027. Following operation and validation, the Company plans to begin preparations for mass production and start accepting orders. The impact of the announcement of this product on the Company’s consolidated financial results for the fiscal year ending December 31, 2026 is expected to be minimal. The Company will promptly disclose any matters requiring further announcement.

PowerX Inc. announced that it and HIGHRESO Co. Ltd. entered into a memorandum of understanding dated July 15, 2026 to explore collaboration on energy infrastructure supporting GPU data centers and AI computing platforms.

In response, there is increasing interest not only in centralized processing at hyperscale data centers but also in distributed processing through container and micro data centers, as well as in achieving stable power supply and decarbonization through integration with local energy sources. Against this backdrop, PowerX and IIJ aim to build and expand power and digital infrastructure that supports an AI-driven society by combining BESS with containerized data centers. To achieve this, the two companies will begin exploring collaboration across several areas, including the joint development of container data centers that integrate the flexibility of BESS with computing platforms, the development of use cases for digital infrastructure utilizing distributed networks, and the creation of power utilization frameworks leveraging BESS. Among the potential applications under consideration are storing electricity at lower cost and supplying it to server equipment within the containers, as well as selling surplus energy stored in the BESS during periods of high demand, taking into account fluctuations in electricity market prices driven by the expansion of renewable energy and shifts in the power supply-demand balance in Japan. Through these initiatives, the companies seek to address the complex, interconnected challenges of securing power, construction capacity, and computing resources, thereby advancing "Watt-Bit Integration." Watt-Bit Integration: A concept that optimizes the convergence of power (Watt) and communications technology (Bit), enabling digital infrastructure that addresses societal challenges such as AI, decarbonization, and regional distribution. PowerX develops and manufactures large-scale BESS in Japan. Leveraging its expertise in container assembling, direct current power control, and thermal management technologies, the company has commercialized the "Mega Power DC," a containerized data center product. Following market validation, PowerX aims to begin mass production of the product.
