WhiteWave Foods has raised its full-year earnings guidance following a jump in first-quarter sales and earnings.

The company said that organic growth in its historical business and the contribution from Earthbound Farm, which was acquired in January, boosted the top line. Sales were up 36% and organic sales grew by 12%.

Operating income increased 29% and the company said that it saw improved margins across its business, with the exception of Earthbound. Net profit increased 35%.

The strength of the first-quarter result prompted WhiteWave to increase its full-year guidance range to $0.95-0.98 per share.
