Bull points
- For Q2, as you notice, we did have the confidence to increase incrementally our gross margins, mainly because we've gotten better visibility to our backlog.
- We do, however, do see some strong headwinds, potentially in the second half, and so we're remaining cautious for the guide in the second half of the year.
- the pipeline in auto has been expanding, and based on our current belief, we would expect to see that ramp later in the year.
Bear points
- Margins on the low end. And although it's in our model, it's on the low end. And we still improve the yields on the modules.
- we go up the trains, this is still at the very beginning, and it's very difficult to predict.
- distribution channel, we don't have a great deal of perfect visibility there, which suggests uncertainty around future inventory levels and potential supply chain issues.
