Cummins Inc. reported its results for the second quarter of 2014. According to the report, second quarter revenue of $4.8 billion increased 7 percent from the same quarter in 2013. The increase year-over-year was driven by stronger demand in on-highway markets and distributor acquisitions in North America. Revenues in North America increased 14 percent while international sales decreased 1 percent compared to the second quarter a year ago. Within international markets, lower revenues in Mexico, Brazil and India offset stronger demand in China.
