Online fast-fashion retailer Shein is planning to make its stock market debut in Hong Kong on Aug. 28, according to a person familiar with the matter, potentially ending the company’s long-running search for a public listing. The Singapore-based company, which was founded in China in 2012, is expected to launch its initial public offering as early as next Wednesday,Reutersreported. A Hong Kong listing would mark the latest stage in Shein’s efforts to go public after the company previously explored listings in New York andLondon. The company has faced slower growth, rising costs and changing conditions in key markets, adding pressure to its public-market debut.
