Imperial Capital analyst David Miller says Netflix's Q1 results were ahead of guidance on "every relevant metric." The "only flaws" were U.S. subscriber guidance missing expectations and a higher effective tax rate for Q2, Miller tells investors in a post-earnings research note. The analyst maintains an Outperform rating on the shares with a $463 price target. However, he reduced his 2019 earnings estimates due to the expectation of higher effective taxes and 2020 earnings estimates due to higher spending and expenses. Nonetheless, Miller continues to see "multiple content-centric catalysts splayed throughout 2019." Netflix investors still have plenty to look forward to in terms of additional catalysts for subscriber growth throughout the year, he writes.
