Lumentum Financial Report and Guidance Strong, Yet Fails to Meet Market Expectations

Light module giant Lumentum's revenue was slightly below the analyst consensus expectation, and coupled with a substantial surge in stock price this year, triggered profit-taking after market hours.

On May 5th, after the U.S. stock market closed, Lumentum released its financial results for the third quarter of the fiscal year 2026, with revenue nearly doubling year-on-year, profit margins expanding significantly, and guidance for the fourth quarter also surpassing market expectations comprehensively. Financial data for the quarter:

• The net revenue for the quarter reached $808.4 million, a 90% year-on-year increase, but slightly below the analyst consensus expectation of $810 million.

• The company's GAAP gross margin rose to 44.2%, and the non-GAAP gross margin reached 47.9%; the non-GAAP operating profit margin reached 32.2%, up 700 basis points from the previous quarter, and up 2,140 basis points from the same period last year.

• The non-GAAP diluted earnings per share were $2.37, higher than the consensus expectation of $2.27, and significantly better than the previous year's $0.57.

• Looking forward to the next quarter, the company expects revenue to be between $960 million and $1.01 billion, with non-GAAP earnings per share between $2.85 and $3.05, higher than market expectations.

CEO Michael Hurlston emphasized that, compared to revenue growth, the profit margin expansion in the near term is more worth focusing on, which comes from operational efficiency, pricing discipline, and product portfolio improvement.

He also stated that as the two core growth engines, Co-Packaged Optics (CPO) and Optical Circuit Switch (OCS), gradually take effect, the company's profitability will be further enhanced.

Despite strong financial reports and guidance, Lumentum's stock price still fell by about 5% after hours, then narrowed to a decrease of 3.46%.

Driven by AI data center demand, the company's share prices have soared by about 170% this year, with analysts believing the market expectations are extremely high, and even a slight 'miss' in revenue can easily trigger profit-taking.

Moreover, the company's balance sheet shows that the current portion of long-term debt has soared from $10.6 million in the previous quarter to $3.24 billion, mainly due to proceeds from convertible preferred stock issued in March 2026. Stock price decline indicates investor concerns about debt structure and whether the recent product portfolio optimization and profit margin improvements can be sustained.

Revenue and Profit Margin Both Soar

Lumentum's core financial indicators for the third quarter all show significant improvement.

Lumentum's GAAP net profit for the quarter was $144.2 million, and diluted earnings per share were $1.50; last year it was a GAAP net loss of $44.1 million, with a loss per share of $0.64.

On a non-GAAP basis, the company's net profit was $225.7 million, and diluted earnings per share were $2.37; last year the non-GAAP net profit was $40.9 million, with earnings per share of $0.57.

CFO Wajid Ali attributed this to several key factors:

Increased manufacturing utilization rates for most product lines, price increases for some products, and favorable product mix.

With the surge in shipments of high-margin data center laser chips, coupled with the company's decisive elimination of low-profit non-core product lines, profitability achieved a qualitative leap.
