Citi analyst Jeremy David tells investors that GoPro CFO Jack Lazar at the firm's conference last week confirmed the company's latest product, the HERO4 Session, has been off to a slow start since launching on July 12. The recent selloff in GoPro shares has been driven by investor concerns about the Session, David tells investors in a research note. To reflect downside from the Session, David cut his Q3 revenue estimate for GoPro to $425M from $438M and Q4 estimate to $560M from $737M, which is $148M below the consensus of $708M. David, however, leaves his post-Q1 of 2016 estimates unchanged, believing the action camera maker's long-term fundamentals remain intact. In fact, he believes concerns around the Session have created an attractive entry point for GoPro shares. His price target for the stock remains unchanged at $90, which is well above yesterday's closing price of $35.73. GoPro missing Q3 estimates and guiding below consensus for Q4 is largely priced in, David argues. The company's 2016 launches are likely to be its biggest, and include a flying camera in first half of the year and the HERO5, likely in spring/ early summer, David writes.
