Performance explodes! Optical module giant Lumentum: Q2 revenue soars 65% year-over-year, AI business order backlog exceeds $400 million, next quarter guidance even more astonishing.

Benefiting from strong demand for Optical Circuit Switches (OCS) and Co-Packaged Optics (CPO), optical module giant Lumentum not only delivered a financial report with both revenue and profit surpassing expectations, but also provided guidance for up to 85% year-on-year growth next quarter, proving its critical role in AI computing infrastructure to the market.

On February 3, global leader in optical and photonic technology Lumentum Holdings announced its financial results for the second quarter of fiscal year 2026. According to the report, for the quarter ending December 27, 2025, the company’s net revenue reached $665.5 million, a 65.5% year-on-year surge, hitting the high end of the guidance range; Non-GAAP operating margin reached 25.2%, expanding more than 1,700 basis points year-on-year, significantly improving profitability far surpassing prior expectations.

CEO Michael Hurlston highly praised the performance: "Lumentum achieved an outstanding second quarter, with revenue up more than 65% year-on-year, and Non-GAAP operating margin up over 1,700 basis points. Revenue reached the high end of our guidance, while profitability and EPS expansion far exceeded previous expectations, fully demonstrating the leverage of our business model."

What’s more noteworthy is the company’s strong momentum in the AI infrastructure field. The OCS business is rapidly expanding to meet extraordinary customer demand, with backlogged orders exceeding $400 million; in the CPO sector, the company has newly secured incremental orders worth hundreds of millions of dollars, to be delivered in the first half of 2027. Hurlston stated, “We are only at the starting line of two enormous opportunities: Optical Circuit Switches (OCS) and Co-Packaged Optics (CPO).” He emphasized that with the explosive increase in bandwidth and energy efficiency requirements in AI data centers, Lumentum is ushering in the strongest growth cycle in its history.

The company is even more optimistic about its outlook. The financial report states that for the third quarter, revenue is expected to reach $780–830 million, up over 85% year-on-year; Non-GAAP operating margin is estimated to further improve to 30.0–31.0%; Non-GAAP EPS is expected at $2.15–2.35, showing strong growth momentum and scaling effects.

After the financial report, Lumentum’s stock price soared more than 5% after hours, and its cumulative increase over the past year exceeded 400%.

Comprehensive Improvement in Profitability, Record-High Operating Margin

Lumentum’s profitability this quarter showed an all-around rise. GAAP gross margin reached 36.1%, up 210 basis points from last quarter and a massive 1,130 basis points from the same period last year; Non-GAAP gross margin reached 42.5%, up 310 basis points sequentially and 1,020 year-on-year.

Profitability at the operating level improved even more significantly. GAAP operating margin jumped from last quarter’s 1.3% to 9.7%, demonstrating a huge improvement of 2,250 basis points year-on-year, turning from -12.8% last year to positive. Non-GAAP operating margin reached 25.2%, up 650 basis points sequentially and 1,730 year-on-year, far above last year’s 7.9%.

The substantial improvement in profitability is directly reflected in earnings per share. GAAP diluted EPS reached $0.89, up from just $0.05 last quarter and a loss of $0.88 in the same period last year; Non-GAAP diluted EPS reached $1.67, up 52% sequentially and soaring nearly 300% year-on-year.

Dual Growth Engines: Components and Systems Advance Together

The synergistic development of its two business lines reflects Lumentum’s comprehensive layout in AI data centers, cloud computing, and next-generation communication network infrastructure. Leveraging decades of photonic innovation, the company provides a complete product portfolio from high-performance lasers and modules to optical subsystems.

From a product line perspective, both Lumentum’s components and systems businesses achieved robust growth.

Component business revenue this quarter reached $443.7 million, accounting for 66.7% of total revenue, up 17.0% sequentially and skyrocketing 68.3% year-on-year, becoming the main driving engine for revenue growth.

System business performed excellently, with revenue of $221.8 million, accounting for 33.3%, up 43.5% sequentially and up 60.1% year-on-year. The system business’s accelerating sequential growth shows strong demand for the company’s comprehensive solutions.

OCS and CPO Become New Drivers, AI Market Demand Explodes

Management particularly emphasized the explosive growth potential of the Optical Circuit Switch (OCS) and Co-Packaged Optics (CPO) businesses.

In the OCS arena, Lumentum is rapidly expanding capacity to meet extraordinary customer demand, with order backlog now over $400 million, highlighting the huge demand for high-speed optical interconnect technology in AI data centers.

In the CPO business, the company secured incremental orders worth hundreds of millions of dollars this quarter, to be delivered in the first half of calendar year 2027. Co-packaged optics technology integrates optical devices directly into the switch chip package, significantly boosting data transmission speeds and lowering power consumption, making it a key technology for next-generation AI training and inference infrastructure.

The company CEO emphasized that the company’s technical roadmap advantages in both optical components and systems make it a key supplier to the world’s leading AI companies. As AI infrastructure construction peaks, Lumentum’s technical and capacity advantages will continually translate into growth momentum for performance.

Robust Financial Position, Abundant Cash Reserves

On the balance sheet, Lumentum maintains healthy financial status. By the end of this quarter, the company held cash, cash equivalents and short-term investments totaling $1.1553 billion, $33.5 million higher than at the end of last quarter, providing ample security for future business expansion and R&D investment.

Net accounts receivable stood at $376.8 million, a substantial increase from $250 million at the end of June and in line with revenue growth. Inventory reached $570.4 million, up $100 million from last fiscal year’s end, showing the company is actively stocking up to respond to strong order demand.

Notably, the current portion of long-term debt in current liabilities reached $3.2402 billion, a sharp increase from $10.6 million at the end of June, mainly due to the reclassification of convertible bonds. However, considering the company's strong cash flow generation and abundant cash reserves, overall financial risk is considered manageable.

Robust Q3 Guidance, Annual Growth Momentum Established

Looking to Q3, Lumentum has provided guidance surpassing market expectations. The company projects revenue at $780–830 million, with the midpoint showing over 85% year-on-year growth and about 22% sequential growth, reflecting continued strong momentum.

On margins, Non-GAAP operating margin is expected to further improve to the 30.0–31.0% range from this quarter's 25.2%, showing continued scale effects and operational efficiency. Non-GAAP diluted EPS is expected to be $2.15–2.35, with the midpoint up 34% from this quarter’s $1.67.

Management states that the company is still at the early stage with OCS and CPO. As capacity ramps up and orders are delivered, there is huge room for future growth. Coupled with stable demand from traditional telecom and industrial manufacturing markets, Lumentum has established a strong growth outlook for the year and is set to continue benefiting from the AI infrastructure construction wave.
