Analysis · LITE · Manufacturing
A standout quarter for Lumentum saw revenue more than double year-over-year to $1.01 billion, fueled by surging AI-related demand for optical connectivity. Non-GAAP earnings per share of $3.23 crushed the prior year's $0.88. Looking ahead, first-quarter fiscal 2027 revenue is guided to $1.225–$1.275 billion, comfortably above the $1.21 billion consensus, with non-GAAP operating margins expanding to 39.5–40.5%. The headline GAAP net loss of $7.2 billion is entirely non-cash, stemming from a $7.8 billion accounting charge for the equitization of convertible notes — a transaction that actually strengthens the balance sheet by reducing debt. With $2.7 billion in cash and a clear AI growth trajectory, the results reinforce the investment thesis.
