Netflix reported strong numbers for its first quarter, but a couple of Wall Street analysts see risks for the company moving forward.
On Monday, the streaming giant reported earnings per share and revenue that met analyst expectations. Netflix shares rose 9.2 percent to a record high as investors cheered the company's strong subscriber growth.
However, Jefferies equity analyst John Janedis said in a note Tuesday the company's margins will be pressured by further content spending moving forward.
The company's forecast for a 12 percent operating margin in the first half of this year compares with its full-year forecast of 10 to 11 percent, given increased spending on content and marketing, Janedis said in the note.
He also noted he expects Netflix "will remain cash flow negative for several years" as it continues to invest in original content. "The burn rate has been a focus," he said. "It is also increasingly likely that this year or 2019 could mark the peak of [free cash flow] losses."
Free cash flow was negative $287 million for the quarter.
Janedis hiked his price target on the Netflix shares to $312 a share from $236, implying a 1.4 percent upside from Monday's closing price.
Barton Crockett, an analyst at B. Riley FBR, said Tuesday that while the company's results were robust, "we still struggle with high valuation and lofty expectations." Netflix stock traded at a price-to-earnings ratio of 219 on Tuesday, one of the highest among S&P 500 companies, according to FactSet.
Crockett also raised his price target on Netflix to $313 from $243, implying a nearly 2 percent upside from Monday's close.
"While we can't responsibly recommend chasing Netflix's equity here, we don't see how one can escape seeing Netflix's surprisingly durable growth as cautionary" for traditional TV, Crockett said in a note Tuesday.
