The company's global streaming revenue for the third quarter totalled $US2.2 billion, of which 40 per cent was generated outside the US.
Operating income was $US106 million (versus Netflix's prior $US64 million estimate) while net income was $US52 million ($US22 million was forecast).
According to the company, the stronger-than-expected subscriber acquisition for the third quarter was driven by "excitement around Netflix original content".
Netflix is continuing to double down on originals. In 2017, the company said, it planned to release more than 1000 hours of premium original programming, up from about 600 hours this year.
Among its originals, Netflix called supernatural thriller Stranger Things, which launched July 15, "the blockbuster of the summer" and noted the series was produced and owned by Netflix.
For one thing, the benefit of that was "it doesn't come with the studio mark- up", Netflix chief content officer Ted Sarandos said on the earnings call.
The company also cited drug-cartel drama Narcos, which returned for a second season in September, saying it had "a positive impact on member acquisition across all of our markets".
In August, Netflix introduced the first half of Baz Luhrmann's The Get Down series about the origins of hip-hop in 1970s New York - its most expensive series ever - but according to third-party research the initial viewer response did not come close to other originals.
At an investor conference in September, chief financial officer David Wells said Netflix was shifting its content spending with the aim of having 50 per cent of the TV shows and movies on its streaming service be original productions during the next few years.
Netflix forecasts 5.2 million global net adds for the fourth quarter, including 1.45 million in the US and 3.75 million internationally.
Average revenue per subscriber for the third quarter grew over 10 per cent year- over-year in the US and international segments.
Also Monday, Netflix disclosed that - for the time being - it is no longer looking to launch its own branded service in China, citing regulatory challenges.
