Founded in 1992, Wooyang is a food manufacturing specialist that produces frozen processed foods and home meal replacement (HMR) products from agricultural, fishery, and livestock raw materials, operating a B2B food manufacturing solutions business for corporate customers.
According to the company's quarterly report, its major customers include manufacturing-distribution firms such as CJ CheilJedang and Pulmuone, as well as foodservice franchises such as Starbucks, Ediya, and Hollys, and it provides a range of manufacturing solutions from raw material import and processing to contract product development and production.
The company also runs its own brands, 'Newtre' and 'Chef Story,' extending beyond pure contract manufacturing into branded products.
Its production base consists of five factories located in Seocheon and Cheongyang in South Chungcheong Province and Cheongsong in North Gyeongsang Province, forming a vertically integrated production system spanning raw purees and pastes to beverage bases, juices, and finished HMR products.
Its flagship product is frozen hot dogs, produced since 2002, and the company was the first in its industry to obtain HACCP certification for a hot dog production line.
In recent years, growing US exports of hot dogs have shifted the company from a domestic-focused player to an exporter, supplying Costco in the United States through Pulmuone.
Since 2024 the company has also begun exporting frozen kimbap to the US market, and it is noted as the only listed company producing frozen kimbap domestically, positioning it to benefit from the broader K-food export boom.
Since the second half of 2025, brokerage reports have repeatedly highlighted the company's position as the domestic market share leader in hot dog HMR products, drawing renewed market attention.
