Lumentum Holdings Inc.

Fourth quarter revenue was $1.01 billion, up 109% year over year. Non-GAAP EPS was $3.23; GAAP gross margin was 47.4%; GAAP operating margin was 27.8%. Non-GAAP gross margin was 50.4%, up 250 basis points sequentially and 1,260 basis points year over year, and non-GAAP operating margin was 36.6%, up 440 basis points sequentially and 2,160 basis points year over year. Components revenue was $649.4 million, up 22% sequentially and 103% year over year, while Systems revenue was $356.9 million, up 30% sequentially and 123% year over year. For Q1 fiscal 2027, management guided revenue to $1.225 billion to $1.275 billion, non-GAAP operating margin to 39.5% to 40.5%, and non-GAAP EPS to $4.05 to $4.35. The midpoint of Q1 revenue implies more than 130% year-over-year growth. The company also said it reduced debt by $1.1 billion through convertible note equitization, took a one-time non-cash GAAP charge of $7.8 billion, ended the quarter with $2.74 billion of cash and short-term investments, and spent $167 million on CapEx.

Michael Hurlston framed the quarter as evidence that Lumentum is benefiting from a secular shift toward optical connectivity for AI infrastructure. He emphasized that demand is broadening across scale-out and scale-across products, while new opportunities in NPO, CPO, CW lasers, ELS modules, and OCS are arriving sooner than expected. His tone was confident and aggressive, repeatedly saying the company is running ahead of prior targets and has visibility into a stronger ramp through 2027 and 2028.

Wajid Ali highlighted the financial leverage in the model: revenue of $1.01 billion and non-GAAP EPS of $3.23 both exceeded expectations, while non-GAAP gross margin was 50.4% and non-GAAP operating margin was 36.6%. He pointed to better manufacturing utilization, favorable mix, and higher pricing on select products as margin drivers, and noted operating expenses rose to support cloud and AI opportunities. On the balance sheet, cash and short-term investments fell to $2.74 billion mainly due to convertible debt conversions, inventory rose $59 million to support growth, and CapEx was $167 million, focused on manufacturing capacity.

Analysts focused on whether Lumentum is moving ahead of its prior financial framework, especially around NPO, ELS, OCS, and the next set of targets. Management said new financial targets will likely be issued at the next OFC and reiterated that several opportunities were not fully included previously, including NPO, CW lasers, and stronger-than-expected OCS. Questions on pricing and backlog drew a response that there was some repricing benefit, but mix was a bigger gross margin driver, with more pricing benefit still expected to flow through. Analysts also asked about Chinese indium phosphide competition and substrate supply; management said it has not seen an impact, believes its EML/CW differentiation remains strong, and said it added AXTI substrate supply because ultra-high-power laser demand has accelerated faster than expected.
