Dear Shareholders:

First of all, thanks for your long-term support to Harmony Electronics. I’d like show my deep gratitude to all of you on behalf of the operation team of the Company.

Looking back at the domestic and international industrial development situation in 2025, the hot topics of emerging technologies such as AI servers and related smart applications have driven the demand for upgrading quartz components. Meanwhile, the demand for consumer electronic products has rebounded, increasing the momentum of pulling goods. Affected by multiple unfavorable factors, including the U.S. Trump administration's tariff policies, China's overcapacity, the ongoing conflict in the Gaza Strip, rising raw material prices, and volatile exchange rates of the Taiwan dollar against the US dollar, the Company's operating performance in 2025 declined slightly compared to 2024, however..

Despite facing a perilous external environment, the Company's management team has adopted a prudent management strategy to enhance product development and innovation capabilities, strengthen management adaptability and improve cost structure so as to maintain steady growth in operations. Now I would like to report to all shareholders the operation of the past year.

The Company’s 2025 operating performance: Its consolidated operating income reached NT$2.871 billion, a decrease of 2.15% from NT$2.934 billion in 2024. The annual consolidated net profit after-tax was NT$47 million, a decrease of 82.15% from 2024. Looking forward to this year (2026), in addition to consolidating the production and marketing benefits of existing products, the proportion of industrial applications, data communications, and other non-consumer electronic products will be promoted in order to create opportunities for breakthroughs. By the end of 2025, our second factory in Thailand started to increase production scale and efficiency, an effort to meet the subsequent market demand for products under the trend of decoupling from China and moving south. Regarding the Company’s 2025 business results and 2026 business plan summary, as well as the impact of future company development strategies, external environmental laws and regulations, and the overall economic environment, the reports are as follows:

(2)Budget implementation status:

The Company didn’t announce the financial prediction publicly in 2025, so it doesn’t have to disclosure the budge implementation status.

(3)Financial revenue & expenditure, and profitability:

(4)Research and development status:

The Company’s product development mainly focuses on quartz components and micro-electromechanical sensing components. Quartz components include quartz crystals, general quartz oscillators, temperature compensated quartz oscillators, piezoelectric controlled quartz oscillators and differential output quartz crystal oscillators. The size of its miniaturized products is reduced from 2.0mm x 1.6mm, 1.6mm x 1.2mm to 1.2mm x 1.0mm; the accuracy can reach a frequency change of ±10~±50ppm under the operating temperature of -40~+150℃℃, meeting the needs of various fields such as consumer electronics products, network communications, automotive applications, AI Server and Optical Communication. In terms of temperature-compensated quartz oscillators, its accuracy can reach 0.5ppm. Micro-electromechanical sensing components focus on the layout of product structure design and packaging technology.

With the advancement of 5G networks, cloud technologies, and AI technologies, the application of communication technology is rapidly entering the fields of home appliances, vehicles, and industries, etc. In order to strengthen the depth and breadth of existing core products, the Company has introduced semiconductor Photo-Etching technology and various sensor integrated packaging, and applied them to ultra-high frequency chip processes.

1. R&D achievements in 2025:

2. R&D projects:

A. Miniaturization and high frequency products

The application of Photo-Etching technology in the semiconductor industry is used to improve the size of miniaturized products and the accuracy of electrode shapes. The current product has been extended to 1.2mm x1.0mm, and in the future, it will develop smaller specifications of 1.0mmx0.8mm. In terms of miniaturized product development, the Company will continue to advance the development of the 1.2 mm × 1.0 mm Inverted MESA ultra-high-frequency series and the Bi-MESA ultra-low-frequency series products. The accuracy and stability of existing quartz crystal series products will continue to be optimized.

B. Low-power high-order oscillators

The frequency of the quartz oscillators that the Company has mass-produced ranges from 1 to 212.5 MHZ. Since its technology is mostly processed by frequency multiplication, the phenomenon of jitter is prone to occur, resulting in signal loss during transmission. In order to solve the above problems, the Company has long-term investment in the development of high-frequency chips with basic frequency. Meanwhile, it continues to expand high unit price and functional quartz oscillator product lines such as VCXO, TCXO, and LV-PECL/ LVDS/ HCSL in AI server and optical communication applications.

C. High-sensitivity products and integrated packaging technology

The Company began to invest in the research of sensing components in 2013, focusing on product structure design and packaging technology layout. After years of hard work, the Company has mastered gold-tin, ceramic, multi-layer substrate, and tubular metal shell-mounted packaging technologies, which are now used in the packaging of pressure gauges, gas sensors, speakers, RF components, bone conduction and other sensing components. The 2026 R&D plan prioritizes the mass production and process optimization of "add-on MEMS speakers," while also driving the development of miniature cooler packaging structures and establishing vacuum packaging technology for bone conduction components. The R&D and process integration of these key technologies aim to improve the performance stability and mass production feasibility of the Company's products, and strengthen its technological competitiveness in related application areas.

III. The future development strategies of the Company, and the impacts of external competitive environment, regulatory environment and the overall business environment.

Looking forward to 2026, AI-related applications remain the main driver of growth for the electronics industry in the future. However, due to negative factors such as memory shortages, soaring oil prices caused by the U.S.-Iran war, and rising prices, international institutions generally expect global economic growth in 2026 to be slower than the previous year.

In response to a challenging external environment, the Company will adjust its business strategy in a timely manner, while strengthening management adaptability, cost control and resource allocation to reduce impacts on the application markets such as AI, 5G communications, automotive electronics and the Internet of Things (IoT). We hope to maintain steady growth in operations and create benefits for all colleagues, customers, suppliers, partners and shareholders.

I firmly believe that with the efforts of all colleagues and the support of all shareholders, Harmony Electronics will face various challenges with a steady business strategy in the new year. In addition, the Company will continue to promote environmental protection, social responsibility and corporate governance issues in order to become a sustainable development enterprise.

At last, best wishes for all of you!
