Hong Kong-listed WuXi Biologics' controlling shareholder Biologics Holdings has sold a 2.43 percent stake in the company for more than $893 million. WuXi Biologics - China's biggest outsourced biologic drugs services company - had seen its shares rise in price to 10 times what they changed hands for at its initial public offering three years ago.

Biologics Holdings is owned by WuXi's founders and institutional investors. The company is led by WuXi chairman Ge Li. Biologics Holdings.

This was the ninth time the company has sold shares in WuXi Biologics and has raised HK$40.7 billion to date.

The continued increase in its stock price is attributed to the company's better-than-expected performance over the past two quarters. For its first-half the company reported a 40.7 percent year-over-year increase in adjusted net profit 734 million yuan ($107.8 million).

The spread of the coronavirus pandemic brought new business to WuXi Biologics. The company reportedly signed more than 10 contracts with international clients - which included antibody research for potential treatments for the coronavirus.
