Vineland-based NFI has acquired Network Logistics Solutions, a contract warehouse management company headquartered in Savannah, Ga.

Terms were not disclosed, but NFI, which as a third-party logistics company specializes in transportation, warehousing and other functions for its clients, announced that the acquisition would add 516 employees to NFI's payroll and an additional three million square feet to the company's contract warehouse space (for a total of 18 million square feet).

Privately held NFI, which had been known for years as National Freight and which also has corporate offices in Cherry Hill, said the acquisition would strengthen its presence in the critical port cities of Jacksonville and Savannah, and give it a new presence in Oklahoma, said Sid Brown, NFI's chief executive.
