Second quarter net profit increased by 41% YoY reaching KRW 9.1 billion while 2021 first half net profit already exceeded 2020 yearly profit KRW 19.6 billion. The company suggests sales are expected to continue further growth, increasing by 7% to 16% YoY for the third quarter 2021.

For the visible segment of the company, WICOP, which offers package-less LED solutions designed with a robust structure, achieved a 68% YoY growth in second quarter 2021 and led to total revenue and profit growth. Micro Clean Pixel to potentially replace the existing display market which was first introduced at CES 2020 started mass production. Seoul expects this could lead to a quantum leap in sales in the future.

On July 15th, 2021, a study conducted by a research team at Korea University showed that the Delta variant (SARS-CoV-2:B.1.617.2) is disinfected 99.3% in just one second when exposed to UV LED Violeds. In addition, Seoul conducted an in-house air disinfection laboratory test (60㎥), which resulted in 90% disinfection in 10 minutes.

On August 4th, Seoul announced a new air disinfection solution which can provide faster and stronger disinfection in a wider space at its on-line press conference. A new plan to supply products for multi-use facilities was announced as well. Seoul added a comment that it is already poised for 2022 future growth through increased investment in first half to solidify a sound foundation for 2nd generation technology WICOP products.
