Lumentum, a major optical communication company, benefits from the huge demand for AI in its financial report

Lumentum, a supplier of optical and commercial laser components, continues to benefit from the huge demand brought by the construction of AI data centers. Its financial performance exceeded expectations, but its stock price fell by more than 3% after trading. The market will also closely monitor the debt situation and whether the previous high-speed growth pace can continue.

According to reports from foreign media, Lumentum announced after 5 US stock market hours that its revenue for the third quarter of fiscal year 2026 (as of March 28) increased by 90% year-on-year to $808.4 million, setting a new historical high. However, it was slightly lower than the analyst estimate of $810 million according to FactSet statistics. Adjusted earnings per share were $2.37, higher than market expectations of $227 million.

According to the financial report, the adjusted gross profit margin for the first quarter increased from 42.5% in the previous quarter to 47.9%, and the adjusted operating profit margin increased from 25.2% to 32.2%, mainly due to strict operations, pricing strategies, and a strong product portfolio.

In terms of financial forecasts, Lumentum estimates fourth quarter revenue to be between $960 million and $1.01 billion, with earnings per share ranging from $2.85 to $3.05, both exceeding market expectations.

Lumentum is mainly engaged in the design and manufacturing of high-performance optical and photonic products, with a product portfolio covering optical communication components such as optical transceivers, as well as 3D sensing modules, lasers, and optical solutions, applied in data centers, telecommunications networks, consumer electronics, and industrial fields.

The AI infrastructure boom is booming, and optical communication is gradually seen as a key technology to solve the bottleneck of AI computing. It is crucial for high-speed transmission of large amounts of data between servers in data center networks, and Lumentum has become one of the most eye-catching concept stocks.

Lumentum received a $2 billion investment from AI chip giant NVIDIA in March and was included in the benchmark S&P 500 index in the same month.

Lumentum's stock price closed at $994.56 on the 5th, and has surged by about 170% since the beginning of the year. After the financial report was released, the stock price fell by 3.5%, which may reflect profit taking and selling pressure. Investors are also concerned about the debt situation and the sustainability of profit growth.

Lumentum's balance sheet shows that the current portion of long-term liabilities in the first quarter surged from $10.6 million in the previous quarter to $3.24 billion, mainly due to the impact of the issuance of convertible special shares in March, which also raised some doubts.
