Aug 12 ( Reuters ) - Shopee-owner Sea Ltd topped market estimates for quarterly revenue on Tuesday, powered by strong growth at its e-commerce business, sending the company's U.S.-listed shares up more than 9% in premarket trading.

Sea also reported strong revenue growth in its financial services unit, due to strong demand for its credit products from small- and medium-sized businesses, while its entertainment segment saw a 28.4% rise in revenue.

Shopee, a popular e-commerce platform in Southeast Asia and Taiwan, with a notable presence in Latin America, has been seeing strong consumer demand, helped by the company's efforts to offer competitive pricing and improved customer experience.

The e-commerce unit, which turned profitable last year and accounts for more than 60% of its overall revenue, reported a 33.7% jump in revenue to $3.8 billion in the April-June quarter.

Sea's digital financial products arm, home to its Monee app that offers services including payment processing, digital wallets and credit services, reported a 70% rise in revenue to $882.8 million.

The Singapore-based tech company reported revenue of $5.26 billion in the second quarter ended June, up 38.2% from last year and compared with analysts' average estimate of $4.98 billion, according to data compiled by LSEG.
