Revenue rose 38% to a record US$5.26 billion in the three months through June, the company said in a statement.
Analysts estimated US$5 billion on average.
Net income jumped to US$414.2 million from US$79.9 million a year earlier, but fell short of the US$444 million analysts predicted.
Sea’s American depositary receipts jumped as much as 20% after markets opened in New York today, their biggest intraday gain in nine months.
The results assuage some concerns about the prospects of e-commerce arm Shopee.
The region’s top online retail platform is battling deep-pocketed global challengers including ByteDance Ltd’s TikTok Shop and Alibaba Group Holding Ltd’s Lazada.
Emerging players like Shein and PDD Holdings Inc’s Temu are also looking to break into the emerging region of 675 million people where more and more shoppers are coming online.
To boost its bottom line, Shopee has been steadily raising the commissions it charges merchants in various core markets by about a third since the start of last year.
The hikes, which bring Shopee’s fees above its rivals, show that Sea is confident it can attract and retain merchants, helped by a broad user base and well-established delivery services.
Shopee’s second-quarter revenue rose 34% to US$3.8 billion, thanks in part to surging commissions and ad revenue.
Sea is also betting on new initiatives from digital finance to logistics to grow its dominance and convince investors of its growth potential.
Its logistics arm SPX Express now handles the majority of Shopee’s billions of parcels annually, while its finance arm – now known as Monee – increased sales 70% last quarter to US$882.8 million.
Bookings at gaming division Garena rose 23%.
“In the past, cash flow from Sea’s gaming arm Garena was used to grow Shopee and Monee, but now Shopee and Monee are in healthier capital positions,” Hussaini Saifee, an analyst at Maybank Securities, said before the results.
“Sea can now invest in further developing Garena which has also made a strong rebound over the last year and a half.”
