Latham & Watkins has advised China’s fourth-largest brokerage by total assets on its $3.6 billion initial public offering in Hong Kong.

GF Securities Co. Ltd. sold 1.48 billion shares at $2.34 each, making it the biggest IPO so far this year in Asia. The Guangzhou-based company, which also provides investment banking and asset management services to its clients, joins other Chinese brokerages such as Orient Securities and Haitong Securities to similarly tap the public market in recent months.
