WEX Inc. signed a long-term agreement with CITGO Petroleum Corp. to provide private label and co-branded universal fleet card services.

WEX will issue fleet cards, provide related payment services to CITGO customers and convert the CITGO fleet card portfolio to its platform. This provides customers with a complete range of information, features and functionality to manage their fleets, according to WEX.

“The agreement with CITGO underscores our commitment to growth in the North American fleet market and offers fleet customers another robust fleet card program option with one of the most recognized brands in the industry,” said Ken Janosick, WEX’s senior vice president of fleet payment solutions.

The new program will include a competitive rebate offer on CITGO fuel through a single-branded proprietary fleet card accepted only at CITGO locations and a co-branded universal card, which can be used at more than 150,000 U.S. fuel and service locations.

"WEX provides the best competitive offerings for our fleet customers, and by working together, we believe we can substantially grow our fleet business,” said Alan Flagg, general manager of light oils marketing for CITGO Petroleum Corp.
