Woori E&L Harootine, founded in 2008 and listed on KOSDAQ, operates around two business pillars. The first is its founding business of display LED backlight unit (BLU) packages and modules, producing LED components for TVs, monitors, notebooks, lighting, and automotive applications.
According to company descriptions, the firm has secured leading domestic and overseas display makers such as LG Display as key customers through years of experience, backed by production capacity in China and Vietnam that supports cost competitiveness.
Past industry surveys placed the company's share of LG Display's LED module market at around 50%, indicating meaningful customer concentration risk.
The second pillar is the 'Harootine' health supplement brand launched in August 2021, which differentiated itself as the first in Korea to apply liposome formulation technology to vitamin products.
In February 2026, the company named national football team captain Son Heung-min as the official brand ambassador for Harootine vitamins to expand brand recognition.
In April 2026, the company changed its corporate name from 'Woori E&L' to 'Woori E&L Harootine,' reflecting the growing strategic weight of the supplement business in its identity.
More recently, it absorbed Woori Green Science to internalize the value chain from raw material R&D to finished product planning and distribution, and has expanded into plant cell culture and natural material research through a collaboration with U.S. plant-cell biotech firm Ayana Bio, along with related medical cannabis research.
Both businesses are manufacturing-based, with the LED segment's performance tied to the display industry cycle and the supplement segment's performance tied to consumer marketing competitiveness.
