Lumentum Holdings Inc. (NASDAQ: LITE) reported fiscal fourth-quarter results on Aug. 11, showing stronger revenue and non-GAAP profit for Q4 2026. The company issued Q1 FY2027 guidance above consensus, citing rising AI data-center optical demand.
Quarter Results and Margins
Lumentum reported fiscal Q4 FY2026 net revenue of $1.01 billion and non-GAAP diluted earnings per share (EPS) of $3.23. The quarter delivered GAAP gross margin of 47.4% and non-GAAP gross margin of 50.4%, with operating margins of 27.8% GAAP and 36.6% non-GAAP. These results exceeded Street expectations.
For the full fiscal year, FY2026 revenue reached $3.014 billion, with non-GAAP diluted EPS of $8.67.
Guidance, Demand Drivers, and Convertible Notes Equitization
The company set Q1 FY2027 revenue guidance between $1.225 billion and $1.275 billion, non-GAAP operating-margin guidance of 39.5% to 40.5%, and non-GAAP diluted-EPS guidance of $4.05 to $4.35. Management said optical links are becoming a primary connectivity layer for AI data-center architectures and described Q4 as showing broad-based traction. The release stated, “Lumentum is positioned at the heart of a secular industry shift.”
Lumentum disclosed a one-time, non-cash $7.8 billion loss on debt extinguishment tied to the equitization of certain convertible notes, which drove a Q4 GAAP net loss of $7.2 billion, or $84.65 per diluted share. The full-year GAAP net loss was $6.935 billion. The company ended the quarter with $2.7 billion in cash, cash equivalents, and short-term investments.
This accounting charge is non-cash and does not affect underlying profitability or near-term liquidity, supported by strong non-GAAP operating metrics and a healthy cash balance. The combination of robust non-GAAP margins, above-range Q1 guidance, and the one-time GAAP charge positions Lumentum to capture strengthening AI data-center optical demand, though the large accounting loss will complicate GAAP comparisons and valuation in the near term.
