Hansen's Preliminary First-Quarter Sales Jump

Hansen Naturalreported higher quarterly sales, citing continued strength of its Monster Energy drinks, and increases in volumes of teas, lemonades and juice cocktails.

Andrew Sawyer, an analyst with Goldman Sachs, said the preliminary first-quarter results imply earnings per share of 28 cents a share, compared with Sawyer's view of 30 cents a share.

In a research note to clients, Sawyer wrote that the shortfall was driven by some gross margin deterioration, and surprising negative operating leverage due to a 48% increase in selling, general and administrative expenses.

Colbert added that the quarter fell a penny short of market expectations at 28 cents a share. He said that the selling, general and administrative expenses were also above view.

Analysts on average expect the company to earn 29 cents a share, before items, according to Reuters Estimates.
