Nov 21 (Reuters) - Singapore-based online gaming and e-commerce firm Sea Ltd reported a 4 percent rise in third-quarter revenue and a wider loss as it boosted marketing spending, in its first earnings report since going public in the United States in October.
The company said its net loss widened to $132.8 million, or 75 cents per share in the quarter ended Sept. 30, from $65.6 million, or 38 cents per share, a year earlier. Adjusted net loss was $127.1 million.
Revenue at the company, which counts China's Tencent Holdings as its biggest shareholder, rose to $94.1 million from $90.5 million. An average of three analysts' revenue estimates was $93.9 million, according to Thomson Reuters data.
Cash revenue, a closely watched measure of performance, jumped 73 percent to $151.7 million.
The company operates in Indonesia, Taiwan, Vietnam, Thailand, the Philippines, Malaysia and Singapore.
It has three platforms - Garena for gaming, which accounts for the bulk of its revenues, Shopee for e-commerce and AirPay for digital financial services.
Shopee's gross merchandise value (GMV) leapt 219 percent to $1.06 billion.
Sea expects 2017 cash revenue of $540 million to $550 million, a rise of 53 percent to 56 percent. It expects GMV for its e-commerce business to be between $3.8 billion and $4 billion, an increase of 230 percent to 248 percent.
