Smithfield Foods’ shares rose over their reduced initial public offering price Tuesday, as the pork producer returned to the stock market about 12 years after China’s WH Group took it private.

Smithfield Foods, the largest pork processor in the U.S., said it priced its initial public offering well below its forecast range, raising $521.7 million for the company and the selling stockholder.

Smithfield Foods ( NASDAQ: SFD) opened for trading at $21.05 before settling back to $20.18 at 12:50 p.m. The early trading values the food processing giant at just over $8.0 billion.
