Hahn & Company has acquired an 85% stake in SK Specialty from SK Inc. for approximately $1.93bn (₩2.6tn), marking a major private equity move in South Korea’s advanced manufacturing sector.

The transaction was finalised just three months after signing the stock purchase agreement in December 2024.

SK Specialty is a global leader in specialty gases critical to semiconductor and display panel manufacturing. The company dominates the global market for nitrogen trifluoride (NF3) and tungsten hexafluoride (WF6), two essential materials for advanced chip production.

The deal was executed through Hahn & Company’s fourth private equity vehicle, Fund IV, which closed last year at approximately ₩4.7tn. SK Inc. will retain a 15% stake in the business, reflecting the company’s strong growth potential.

Hahn & Company said it remains committed to preserving employment at SK Specialty and will continue investing to enhance the firm’s technological edge and global competitiveness.

“We are very pleased to acquire SK Specialty, a global leader in specialty gases and a pivotal player in advanced manufacturing,” a representative from Hahn & Company stated. “We will make generous investments for future growth and reinforce SK Specialty’s position in the domestic and global industrial ecosystem.”

The deal underscores Hahn & Company’s broader strategy of acquiring high-performing industrial assets and partnering with Korea’s leading conglomerates to build globally competitive businesses.
