AXT Stock Surges on Blowout Earnings and $87 Million Lumentum Deal

Shares of AXT Inc. (NASDAQ: AXTI) surged more than 23% in after-hours trading after the compound semiconductor substrate manufacturer announced second-quarter financial results that far surpassed analyst expectations and a landmark supply agreement with Lumentum.

Blockbuster Earnings Report

The company's performance for the second quarter of 2026 marked a significant financial turnaround. The results, which AXT described as an "inflection point," handily beat Wall Street consensus forecasts.

• Revenue: $47.6 million, approximately 57% higher than the consensus estimate of $30.4 million.
• Adjusted EPS: $0.19, more than double the forecasted $0.07 per share.
• Growth: Revenue increased 164% year-over-year and 77% sequentially from the first quarter of 2026.
• Profitability: Gross margin expanded dramatically to 45.0% from just 8.2% in the same quarter a year prior, leading to the company's first clearly profitable quarter in recent memory.

Landmark Lumentum Agreement

Adding a significant long-term catalyst, AXT also revealed a capacity reservation agreement with Lumentum Operations for its indium phosphide wafer substrates. The deal secures priority supply for Lumentum through the end of 2031.

Under the terms of the agreement, Lumentum will pay AXT two separate deposits of $43.5 million, for a total of $87 million. This multi-year contract provides AXT with substantial revenue visibility and underscores the surging demand for its materials, which are critical for data center optical connectivity.

Market Context and Outlook

CEO Morris Young stated that the quarter included the company's highest indium phosphide revenue on record, driven by demand related to artificial intelligence infrastructure. The positive news was amplified by the fact that it followed a recent price target cut from B. Riley Financial, which had lowered expectations ahead of the report.

The powerful combination of a historic earnings beat and a long-term, deposit-backed supply contract with a key customer provided a dual catalyst for the stock. This suggests to investors that AXT has entered a new growth phase underpinned by sustained demand in the AI and data center markets.
