Business
GMB Corporation, founded in 1962, is an independent automotive parts manufacturer that develops products across three categories: driveline, power transmission and steering parts (centered on Universal Joints, Water Pumps, and Bearings), cooling system parts, and bearings. The business is built on two pillars—parts for new vehicles and aftermarket parts—and the company has 15 consolidated subsidiaries spanning South Korea, China, Europe, the United States, Thailand, India, and Australia. Its major customers include the Hyundai Motor Group (accounting for over 16.5% of net sales in FY2026 (ending March 2026)) and other finished vehicle manufacturers and affiliated parts makers, as well as aftermarket parts importers worldwide. Consolidated net sales for FY2026 (ending March 2026) reached ¥105,281 million.
Business Model
In the new-vehicle parts business, centered on GMB KOREA CORP. in South Korea, the company provides stable supply to vehicle manufacturers such as the Hyundai Motor Group based on long-term trading relationships. In the aftermarket parts business, the Japan head office offers a wide product lineup under the GMB brand to importers around the world, differentiating itself through a balance of price and quality. Manufacturing is handled by regional group bases, with Japan and South Korea leading Advanced R&D and Product Development, adopting a vertically integrated business model.
Company Strengths
GMB KOREA CORP. maintains a long-standing business relationship with the Hyundai Motor Group. In FY2026 (ending March 2026), sales to Hyundai Motor Company reached ¥9,327 million (8.9% of total), while sales to Hyundai Transys Inc. reached ¥7,982 million (7.6% of total). The South Korea segment recorded sales of ¥67,530 million, accounting for approximately 64% of the group's total sales, making it the core of earnings.
By having two axes—new-vehicle parts (South Korea, Europe, United States, India, etc.) and aftermarket parts (Japan, North America, Australia, etc.)—the company diversifies risk against demand fluctuations in specific markets. In FY2026 (ending March 2026), sales by product category were diversified as follows: drive, transmission and steering system parts ¥47,503 million, cooling system parts ¥42,792 million, and bearings ¥14,587 million.
GMB KOREA CORP.'s technical research institute has 160 employees, and R&D expenses for FY2026 (ending March 2026) totaled ¥1,978 million. The company develops and mass-produces electrification-compatible products such as Electric Water Pumps, Integrated Thermal Modules (ITM), and electric oil pumps, and increased sales have been confirmed in the new-vehicle markets of South Korea and China.
ENVALITH's Perspective
Performance Trend
Revenue for FY2026 (ending March 2026) was ¥105,281 million (up 1.5% year on year), marking five consecutive fiscal years of revenue growth, although the growth rate has been on a decelerating trend. Operating profit reached ¥3,321 million, the highest level in the past five fiscal periods, supported by a decrease in retirement benefit expenses in the South Korea segment, increased sales of products for electrification, and price revisions for aftermarket parts. However, net income turned negative, resulting in a net loss of ¥1,035 million, highlighting a structural issue in which improvements in operating profit are not reflected in the bottom line. The structure in which external factors such as exchange rate fluctuations (Korean won and yen) and production trends at the Hyundai Motor Group significantly affect performance remains unchanged.
Growth Strategy
The company aims to achieve net sales of ¥130.0 billion through four strategic pillars: electrification-compliant products, global new facility expansion, aftermarket sales expansion, and response to OEM outsourcing needs.
Mass production and sales expansion of electrification-compliant products such as Integrated Thermal Module (ITM) and Electric Water Pumps in South Korea, China, and Europe. Sales growth was confirmed in the South Korea and China segments in FY2026 (ending March 2026), and these products are beginning to function as a key revenue driver.
New plants have been launched in the United States and India to meet customers' local delivery needs. As of FY2026 (ending March 2026), both sites continued to post losses (United States: loss of ¥854 million; India: loss of ¥141 million), reflecting an ongoing upfront investment phase. Capital expenditure in the United States segment increased significantly.
Continuously revising sales prices in aftermarket parts markets worldwide to improve profitability. In parallel, the company is promoting the introduction of new items by expanding coverage for large vehicles and construction machinery. This is believed to have contributed to some extent to the improvement in operating profit in FY2026 (ending March 2026).
Responding to the OEM outsourcing needs of European vehicle manufacturers by expanding sales of new-vehicle parts such as Universal Joint. The Europe segment recorded a profit of ¥73 million in FY2026 (ending March 2026), maintaining profitability. The start of local production of Electric Water Pumps at the Romania plant is positioned as a medium-term strategic initiative.
