South Korea’s SK Hynix plans to issue American depositary receipts on Nasdaq. The world’s second-largest memory-chip maker said it is looking to raise more than $29 billion, and expects trading to begin July 10. The offering would be one of the biggest share sales in history, comparable to Saudi Aramco’s 2019 initial public offering and surpassing Alibaba’s U.S. ADR offering in 2014.
