Green Energy Business Momentum Rises; Buima’s October Revenue Reaches NT$260 Million, up 4.86% YoY

Buima Co., Ltd. (hereinafter referred to as "Buima"; Stock Code: 5543) announced today that its consolidated revenue for October 2025 reached NT$260 million. Benefiting from the steady progress of orders in the green energy and construction engineering businesses, October revenue grew by 4.86% compared to the same period last year. Cumulative consolidated revenue from January to October 2025 totaled NT$2.585 billion, a year-on-year decrease of 6.7%. As the overall operational structure is gradually adjusted alongside business transformation, the boost in green energy business momentum is expected to create a solid foundation for future operations.

Buima stated that the revenue growth in October was primarily driven by a recovery in shipment momentum for the battery module business. Several international clients accelerated the development of emerging applications such as smart wearable devices, Low Earth Orbit (LEO) satellites, and unmanned vehicles. The resulting increase in battery module orders further drove a 1.76% year-on-year increase in green energy business revenue for October. Additionally, multiple public construction orders in Taiwan were recognized steadily according to construction progress, simultaneously contributing to overall revenue performance.

Buima pointed out that the Group continues to actively deepen its green energy business transformation to establish its market positioning as a provider of new-generation energy storage and usage solutions. The Group leverages:

a. Possession of a Class A General Contractor license and a rich track record in EPC turnkey engineering, offering one-stop solutions from engineering design and system integration to site operation and maintenance;

b. Independent development of battery modules and Energy Management Systems (EMS), with products covering diverse applications such as industrial, medical, BBU backup systems, LEO satellites, and unmanned vehicles;

c. Its proprietary distributed energy storage wall system, B.E.S.T (Buima Energy Storage Tile), which can be flexibly applied in front-of-the-meter and behind-the-meter storage scenarios. By integrating ESCO energy management solutions, it assists users in balancing grid loads and reducing electricity costs, comprehensively laying out the four major areas of "Energy Generation, Storage, Saving, and Usage."

Buima's competitive advantage lies in its ability to simultaneously integrate engineering design, battery module manufacturing, and energy management. This allows the company to provide owners with complete "construction to O&M" services and strengthen international market expansion through local partners. Notably, global smart wearable products maintain growth, with international brands launching new products recently. Additionally, shipments of battery modules for LEO satellite applications have the opportunity to ramp up in response to client demand. Furthermore, the new distributed energy storage wall system, B.E.S.T (Buima Energy Storage Tile), is expected to be implemented in two additional EV charging demonstration sites in the Netherlands by the end of the year, which is expected to further expand overall green energy business performance.

Looking ahead, the accelerating waves of energy transition and corporate carbon neutrality trends are driving continued expansion in energy storage and electrification market demand. Buima remains committed to deepening technical R&D and product innovation in its green energy business. Simultaneously, the Group is actively seeking strategic alliances and partners to elevate its global market competitiveness, transforming towards high value-added directions to create strong operational growth in the medium to long term.
