Another view on MACOM Technology Solutions Holdings valuation

The first narrative leans on future earnings and a higher analyst fair value for MACOM Technology Solutions Holdings. A simple P/E cross check points in the opposite direction. The stock trades on 85.3x earnings compared with peers at 55.9x, the US Semiconductor industry at 47.2x, and a fair ratio of 37.4x.

This gap means you are paying a much richer price than both peers and the fair ratio the market could move towards, which increases valuation risk if growth or margins do not keep pace with expectations. How comfortable are you with paying that kind of premium for MACOM today?
