Truck engine manufacturer Cummins has reported results for the second quarter of 2014, showing revenue of $4.8 billion increased 7% 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, according to the company.

Revenues in North America increased 14% while international sales decreased 1% compared to the second quarter a year ago. Within international markets, lower revenues in Mexico, Brazil and India offset stronger demand in China.

Net income in the second quarter was $446 million, or $2.43 per diluted share, compared to $414 million, or $2.20 per diluted share, in the second quarter of 2013, a 7.7% gain.

"Demand is growing in on-highway markets in North America this year as the economy improves and we have gained market share in medium duty truck and bus markets. Our components business delivered very strong results in the second quarter generating record sales and profits," said Chairman and CEO Tom Linebarger. "Earlier this month we raised the quarterly dividend by 25% and the board of directors also approved a new $1 billion share repurchase program, consistent with our commitment to return 50% of operating cash flow to shareholders and reflecting our confidence in the Company's future."

Based on the current forecast, Cummins said it expects full year 2014 revenues to grow between 8% and 11%, up from its previous forecast of growth of between 6% and 10%, due largely to improving demand in North America.
