BOULDER - Boulder Brands Inc., a natural foods company, on Thursday reported a 15.2 percent increase in revenue for its first quarter that ended March 31.

Boulder-based Boulder Brands (Nasdaq: BDBD) recorded first-quarter revenue of $122.9 million compared with revenue of $106.7 million for the same period a year ago.

Income for the quarter was $412,000, or 1 cent per diluted share, compared with $3.9 million, or 6 cents per diluted share, for the same quarter a year ago.

Boulder Brands' chief executive and chairman Stephen Hughes said that while the company continued to see strong sales momentum, "our bottom line results were muted due to higher than expected egg white prices, which are an important ingredient in our gluten-free bread business, as well as the mix shift to our natural segment, which has lower gross margins."

"The natural segment, which includes Udi's, Glutino and EVOL, represented 60 percent of our total net sales and reported a strong organic net sales increase of 39.5 percent," Hughes said.
