HIOKI ELECTRIC VIETNAM COMPANY LIMITED, a subsidiary of HIOKI (headquartered in Ueda, Nagano, Japan; President: Takahiro Okazawa), opened an after-sales service center on May 15, 2026, to handle inspections and repairs for the company's products.

With the opening of this center, the company aims to establish a prompt repair system and improve customer satisfaction. Furthermore, it intends to expand sales of its products in Vietnam and strengthen business transactions with global corporations operating locally.

### Overview - Location: Inside HIOKI ELECTRIC VIETNAM COMPANY LIMITED (Office E, 12th Floor, Taisei Square Hanoi, 289 Khuat Duy Tien Street, Dai Mo Ward, Hanoi City, Vietnam) - Opening Date: May 15, 2026 - Business Scope: Inspection and repair of HIOKI products (fault diagnosis, parts replacement, adjustment, and operation verification), and initial diagnosis and technical support upon malfunctions. - Purpose: To improve customer satisfaction by building a prompt repair response system, and to expand sales and business transactions with global corporations operating in Vietnam. - Staffing: 2 people (1 Japanese expatriate, 1 Vietnamese staff member)

### Message from Representative Kazuhiro Takezawa, President of HIOKI ELECTRIC VIETNAM COMPANY LIMITED: "In recent years, Vietnam has maintained a high GDP growth rate of 6-7%, with an inflow of $30 billion annually in Foreign Direct Investment (FDI), and overseas investment is expanding, especially in the manufacturing sector. Establishing a local after-sales service system in such a rapidly growing market is a vital initiative for us. By providing consistent support even after product introduction in Vietnam, where many global investments are concentrated, we aim to enhance the value of our electrical measurement solutions that support our customers' operations and contribute to the country's industrial development."

### Background Against the backdrop of the 'China Plus One' strategy, the entry of manufacturing industries and production shifts to Vietnam have been accelerating. Accordingly, the importance of maintenance systems that support stable local operations has risen significantly.

Previously, troubleshooting for product malfunctions was primarily handled by overseas bases, including the Japanese headquarters, which led to issues such as long lead times and increased downtime for customers.

Given this, HIOKI established a sales subsidiary in Vietnam in 2025 to deepen market penetration through building a sales network and enhancing after-sales services. Now that a system for the manufacturer to provide direct after-sales service is in place, the center has been opened. This will realize shortened repair lead times and faster initial responses to malfunctions, contributing to the minimization of customers' downtime and maintenance of stable operations.

While the products currently covered are limited, the company plans to gradually expand the range in the future.

### Features - Shorter lead times and faster problem resolution through local support. - High-quality repair services provided through direct manufacturer handling. - Consistent and prompt response from initial diagnosis to repair upon malfunctions. - Multilingual support available in Japanese, English, and Vietnamese with dedicated Japanese and Vietnamese staff.

### Future Outlook Moving forward, in addition to expanding the range of products subject to repair, HIOKI plans to advance the provision of calibration services to further strengthen its after-sales functions. Specifically for calibration, the company aims to build a system compliant with the international standard ISO 17025 to provide highly reliable services.

Furthermore, the company is considering on-site services tailored to customer needs to realize a prompt and flexible support system locally.
