Sono International, a unit of Sono Trinity Group, has launched the process to list on Korea's main stock market.
Sono International said Wednesday that it submitted a preliminary listing review application to the Korea Exchange on Sunday for a KOSPI listing. Daishin Securities and Mirae Asset Securities are serving as joint lead managers.
Sono International is a hospitality company operating about 15,000 hotel and resort rooms across 21 locations in Korea and 22 overseas. It also runs leisure facilities including ski resorts, water parks, equestrian centers, and the Sono Felice Country Club.
The company has been expanding its overseas business. Sono International entered overseas markets in 2020 with the management of Sono Belle Hai Phong in Vietnam. It subsequently acquired the "33 Seaport Hotel New York" in New York, the "Waikiki Resort Hotel" in Hawaii, the "Normandy Hotel" in Washington, D.C., and the "Hotel Dame des Arts" in Paris, expanding its footholds across the Americas, Europe, and Southeast Asia. The company plans to expand its overseas hotel and resort operations to 55 sites by 2029, centered on the Asia-Pacific region.
Earnings have also improved. Sono International recorded revenue of 968.8 billion won and operating profit of 248.2 billion won in 2025. The company said it has demonstrated operational stability by maintaining an operating profit margin exceeding 20 percent every year.
Through the listing, Sono International plans to strengthen the competitiveness of its domestic and overseas businesses and accelerate the construction of an integrated service platform linking hotels and aviation.
"With the KOSPI listing as a turning point, we will strengthen customer-focused content and enhance our competitiveness in Korea and the Asian region," a Sono International official said. "Over the medium to long term, we will diversify our business portfolio to grow into a global hospitality company with both stability and growth potential."
