Haein was founded in 1960 as Haein Sangsa Co., Ltd. and listed on the KOSPI market in 1988, operating as a specialized construction equipment and engine distributor.
Its core business is serving as the official domestic dealer for Caterpillar, importing and selling excavators, skid loaders, wheel loaders and other construction equipment while providing maintenance, parts and rental services.
The company has diversified its revenue base by adding marine and industrial engine and generator distribution, logistics equipment, industrial equipment and renewable energy-related businesses.
Revenue is largely composed of merchandise sales (imports) of construction equipment, engines, generators and logistics equipment, supplemented by parts sales, maintenance income, rental income, construction income, power sales and product sales. The company holds three unlisted subsidiaries, including Haein Resources.
In the first half of 2026, it launched Caterpillar's next-generation skid loader and a new wheel excavator, the M314, tailored for urban job sites, alongside efforts to strengthen smart equipment supply and digital management systems.
Unlike domestic original equipment makers such as HD Hyundai Construction Equipment, Haein competes as a dealer built around the distribution and service network for the global Caterpillar brand.
As a result, its performance is sensitive to external variables such as Caterpillar's global supply strategy, domestic construction and shipbuilding order cycles, and the won-dollar exchange rate.
