Shares in Hilton Hotel Corp. rose 3 percent Wednesday after the company announced a doubling of earnings due to its acquisition of the U.K.’s Hilton Group.

Hilton reported fourth quarter net income of $207 million (50 cents per share), a 97 percent jump from $105 million (26 cents) for the same period a year earlier. Revenue for the Beverly Hills-based hotel owner and operator was up 107 percent to $2.23 billion, slightly above analysts’ $2.20 billion forecast.

On a worldwide basis, revenue per room grew nearly 11 percent on strong rate increases and high demand in most markets. The results were padded by Hilton’s $5.7 billion purchase last year of Hilton Group, which operated Hilton hotels outside the United States.

Shares in Hilton rose 99 cents to $35.39.
