Hansen Natural Corp. reported fourth quarter net income of $45.1 million (45 cents per share), more than twice what the company reported in the same period a year earlier. The results beat analysts’ expectations of 38 cents per share in profit, according to Thomson Financial.

Sales of the Corona-based drink maker climbed 63 percent to $247 million on strong sales of its Monster Energy and Monster M-80 energy drinks, as well as its newer Java Monster, which is a non-carbonated, dairy-based coffee drink. Sales also smashed Wall Street’s estimates of $212 million.

However, the company reported that its margins fell to 51 percent in the fourth quarter from 53 percent last year due to high costs.

For the full year, Hansen’s profit climbed 53 percent to $149 million ($1.51 per share), while sales rose 49 percent to $905 million.

“The energy category continues to show strong growth and the Monster Energy brand continues to grow in excess of the overall category growth,” Chief Executive Rodney Sacks said in a statement.

Shares in Hansen were stung by volatile trading Friday, losing 6.6 percent to $41.23 in early trading on the Nasdaq.
