“Two Consecutive Years of Double-Digit Growth”: Yoon & Yang Reappoints Managing Partner Lee Myungsoo

Management Partners Kang Youngho and Si Jinguk Also Reappointed
Revenue Up 35% in Two Years... New Three-Year Term

Yoon & Yang said it held a partners’ meeting on October 26 and reappointed managing partner attorney Lee Myungsoo, a member of the 29th class of the Judicial Research and Training Institute, as managing partner. Kang Youngho, a management partner from the 30th class, and Si Jinguk, a management partner from the 32nd class, were also reappointed. Their new three-year terms will begin on January 1, 2027.

The current leadership, which took office in January 2024, has driven revenue growth and organizational expansion during its term. Yoon & Yang’s revenue rose 20.1% in 2024 and 12.5% in 2025, marking two consecutive years of double-digit growth. Cumulative growth over the two years exceeded 35%. The firm said revenue grew by more than 10% year over year in the first half of 2026 and forecast that full-year revenue would exceed KRW 300 billion for the first time.

The number of professional staff has also increased from 502 in the leadership’s first year to approximately 620 today. Last year, the firm established practice groups (PGs) that bring together experts from different fields and strengthened the authority and responsibilities of frontline leaders. It said that, alongside an increase in major cases involving financial regulation, key practices including antitrust, intellectual property (IP), labor, serious accidents, and mergers and acquisitions (M&A) also grew steadily.

Major achievements include winning a lawsuit over the forfeiture of a KRW 250 billion contract deposit related to the acquisition of Asiana Airlines, and securing acquittals at every level of the courts in criminal cases related to the Samsung C&T-Cheil Industries merger. In advisory work, the firm advised on the comprehensive share swap between Naver and Dunamu; NH Nonghyup REITs Management’s KRW 860 billion acquisition of D Tower Donuimun; Hanwha Life’s acquisition of U.S. brokerage firm Velocity; and The Carlyle Group’s acquisition of control of KFC Korea.

Yoon & Yang recently opened a Gangbuk office at the Seoul Finance Center in Gwanghwamun, Seoul, and expanded its recruitment of experts in areas including criminal law and finance, antitrust, cross-border matters, nuclear power, defense, and constitutional litigation. It also raised the retirement age for partner attorneys from 63 to 65.

The reappointed leadership plans to recruit more professional staff and strengthen its capacity to take on major cases during the new term, guided by a “customer-first” principle. The firm also plans to increase investment in emerging industries such as artificial intelligence (AI), environmental, social, and governance (ESG), healthcare and biotech, and digital finance, and to operate PGs and task forces (TFs) organized by industry and issue on an ongoing basis.

Managing partner attorney Lee worked at the Financial Supervisory Service for 10 years before joining Yoon & Yang in 2010, where he led the firm’s financial practice group. He was elected a management partner in 2017 and participated in the firm’s management for six years before taking office as managing partner in 2024.

“I feel a great sense of responsibility now that my partners have placed their trust in me once again,” Lee said. “Over the next three years, amid a rapidly changing legal market and regulatory environment, I will continue working to build a law firm that provides clients with the specialized solutions they truly need and grows together with them.”
