Citi analyst Mark May downgraded Roku to Sell from Neutral and lowered his price target for the shares to $50 from $53. The stock is up 110% year-to-date and near all-time highs, May tells investors in a research note. The analyst notes Roku trades at a 70% premium to peers and believes that recent changes in the over-the-top streaming landscape could create greater competition. Further, Roku's Platform segment revenue growth could be impacted this year due to tough comps, May tells investors in a research note.

Wedbush lowered the firm's price target on Roku to $80 from $120 and keeps an Outperform rating on the shares ahead of the company reporting Q1 results after market close on Thursday, April 25. The firm expects Roku to report Q1 revenue of $855M, versus consensus of $849M and guidance of $850M, along with adjusted EBITDA of $5M, versus consensus of $3M and guidance of breakeven. However, the firm applies a lower multiple on its discounted 2030 EPS estimate, stating that while it had been previously sanguine about Roku's e-commerce opportunity, it is "less so" as it became aware of some competitive disadvantages for Roku and its need to ramp investment to rise to the level of competition in the space.
