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 and its Chinese parent raised around $522 million from the U.S. pork giant's initial public offering after pricing shares below their marketed range.

Smithfield Foods does not plan to close more U.S. pork processing plants, Chief Executive Shane Smith said on Tuesday, as the company returned to a U.S. exchange after more than a decade in a spinoff by Hong Kong-based WH Group .
