Lumentum Holdings surged 521% in a year, now trading at 40.7x FY27 earnings, reflecting aggressive growth expectations.
Revenue and margins are ramping rapidly, with supply-constrained products, multi-year customer agreements, and strong order momentum supporting management's $40 FY28 earnings power target.
Valuation is not excessive versus forward growth, but a limited margin of safety exists; execution risks and customer concentration remain material concerns.
I rate LITE a hold with an upside bias, as current pricing already reflects much of the anticipated growth and leaves little room for missteps.
