Graham Packaging Holdings Company, which recently bought the Tetra Pak plant in Joplin, had a 138 percent gain in net sales for the first quarter and a 28 percent gain in operating income earlier this month, according to a company news release.
In the release, Graham CEO Phillip R. Yates said net sales for the first quarter were $620.5 million, an increase of $360.2 million from the previous year. Yates attributed much of the increase to the company's acquisition of a number of other companies, including Tetra Pak.
