Business Details

The sole business segment of the River Eletec Group, handling research and development, manufacturing, and sales of crystal products centered on crystal units and crystal oscillators on an integrated basis. The major customer is Taiwan's TXC Corporation (approximately 48.7% of net sales). Focus markets include mobility (automotive), medical/healthcare, IoT wireless communications, and next-generation digital infrastructure (data centers, etc.). Manufacturing is handled by Aomori River Techno Co., Ltd. and Xi'an River Techno Crystal Co., Ltd., while sales are conducted through a four-company structure domestically and overseas.

Recent Overview

Achieved increased revenue and reduced losses. Strong profit improvement in the fourth quarter, with all profit levels expected to turn positive in the next fiscal period.

For the full year of FY2026 (ending March 2026), net sales reached ¥5,784 million (+1.5% year on year), achieving revenue growth. Strong contributions came from industrial equipment and medical/healthcare applications. On the profit side, the company was unable to fully absorb cost increases from rising raw material prices and labor costs, resulting in an operating loss of △¥70 million, though this improved from the prior period (△¥75 million). Strong profit improvement was achieved in the fourth quarter. The company established its automotive-related structure through the acquisition of IATF16949 certification (December 2025). For FY2027 (ending March 2027), the company forecasts net sales of ¥5,943 million (+2.7%), operating income of ¥84 million, ordinary income of ¥23 million, and net income of ¥2 million, with each profit level expected to turn positive. The assumed exchange rate is 1 US dollar = ¥155.

Key Products

product
Tuning Fork Crystal Unit

While the first half was affected by a decline in orders for smartphones, the second half saw a significant recovery in orders, mainly for medical/healthcare applications, contributing to the reduction of the full-year loss. Continued stable growth is expected as an existing core field.

product
AT-Cut Crystal Unit

A crystal unit widely adopted for industrial equipment and automotive applications. The acquisition of IATF16949 certification is accelerating entry into the global automotive supply chain, and expansion of orders is expected from the next fiscal period onward.

product
KoT-Cut Crystal Device "KCRO-05"

An ultra-low phase noise crystal oscillator developed for 1.6T optical transceivers, a core technology for next-generation data centers. Following its announcement in December 2025, sample requests and design projects from overseas have increased since the start of the new year. Demand for the 625MHz product is expected to enter an expansion phase toward 2028, although there is a tendency for the overall market adoption schedule to be delayed relative to initial expectations.

product
Crystal Oscillator (General-Purpose)

A general-purpose crystal oscillator widely adopted for IoT wireless communications and industrial equipment applications. Strength in industrial equipment demand contributed to the increase in revenue in FY2026 (ending March 2026).

Growth Drivers

  • Continued revenue growth driven by expanding demand for industrial equipment and medical/healthcare applications (full-year FY2026 (ending March 2026) revenue up 1.5% year on year)
  • Accelerated entry into the global automotive supply chain and order expansion following IATF16949 certification acquisition (December 2025)
  • Expansion into next-generation data center and 1.6T optical transceiver markets driven by increased overseas sample requests and design projects for the ultra-low phase noise crystal oscillator "KCRO-05" (demand for the 625MHz product expected to enter an expansion phase toward 2028)
  • Recovery in orders for tuning fork crystal units for medical/healthcare applications (significant recovery achieved in the second half)
  • Improved profitability through enhanced production efficiency and continuous cost reduction (operating income of ¥84 million forecast for the next fiscal period, turning positive)
  • Strategic concentration of resources on next-generation digital infrastructure, mobility, and medical/healthcare markets under the medium-term management plan "R2027"

Risks

  • Continued cost increase factors such as rising raw material prices and labor costs, which remain difficult to fully absorb through revenue growth
  • Risk that the full-scale rollout of the 1.6T optical transceiver market for next-generation data centers will be delayed relative to initial expectations
  • Customer concentration risk due to sales concentration in the major customer, Taiwan's TXC Corporation (approximately 48.7% of net sales)
  • Continued high level of interest-bearing debt (short-term borrowings of ¥348 million + current portion of long-term borrowings of ¥1,403 million + long-term borrowings of ¥2,911 million, totaling ¥4,663 million) and interest rate rise risk; interest coverage ratio of 5.3x (improved from 3.5x in the prior period but still at a low level)
  • Uncertainty in the external environment, including US tariff policy, geopolitical risk, and prolonged stagnation of the Chinese economy
  • Sluggish growth in existing products due to delayed recovery in smartphone demand and stagnation in the low- to mid-price market segment
  • Continued pressure on profitability due to ongoing upfront investment burden related to new product development, etc.
