Buima Deepens Green Energy Transformation; Energy Storage Wall Debuts at EES Europe to Boost Overseas Operations

Buima Co., Ltd. (hereinafter referred to as "Buima"; Stock Code: 5543) announced today that its consolidated revenue for April 2025 was NT$257 million, a month-over-month increase of 13.6%. Cumulative consolidated revenue from January to April reached NT$1.038 billion, a decrease of 10.63% compared to the same period last year. Buima stated that the year-on-year revenue decline is primarily due to the ongoing adjustment of its business structure and a strategic focus on transformation within the green energy sector, aiming to lay a more stable foundation for mid-to-long-term operations.

In May, Buima participated in the annual EES Europe 2025 (The electrical energy storage exhibition), highlighting its new-generation energy storage product, the "Energy Storage Wall System" (B.E.S.T, Buima Energy Storage Tile). This system features BBU (Backup Battery Unit) characteristics and a patented modular series/parallel design, allowing for flexible expansion of storage capacity and voltage elevation to high-voltage ranges. Paired with Buima’s proprietary EMS (Energy Management System), it effectively monitors battery temperature, voltage and current changes, and usage patterns. Functioning as a UPS (Uninterruptible Power Supply) and voltage boost backup, the distributed energy storage forms a virtual grid, positioning it as a "new-generation energy storage and usage solution" widely applicable in diverse scenarios such as enterprises, public facilities, and EV charging.

The recent large-scale blackout in the Iberian Peninsula has deepened market attention regarding distributed energy storage and the construction of grid resilience. Combined with the continued advancement of global renewable energy policies and the clear trend of vehicle electrification, Buima is well-positioned with its Energy Storage Wall system, which has officially obtained European safety testing reports. The company continues to optimize production efficiency. As the Group actively expands order performance for the Energy Storage Wall system, increases overseas demonstration sites, and deepens business alliance synergies with local agents, these efforts are expected to drive strong growth in its green energy business.

Looking ahead, Buima remains committed to its strategy of "cost reduction and efficiency enhancement." The company will continue to optimize its domestic wall panel business in China and strengthen export orders for its proprietary metal building materials. Simultaneously, the primary goal of fully driving the transformation of the green energy business remains unchanged. Regarding the green energy sector, Buima has received multiple inquiries for cooperation opportunities regarding distributed energy storage wall applications. The company is actively expanding order intake in markets including Taiwan, Japan, the Netherlands, the UK, and Germany. These efforts aim to accelerate the mass production phase of the Energy Storage Wall product, enhance Buima’s competitiveness in the green energy business, and create positive operational results for the future.
