The company’s revenue is derived primarily from substrate sales across applications such as 5G infrastructure, data center connectivity, lasers, sensors, and satellite solar cells, with a significant presence in the Asia Pacific region.
Performance Analysis
In Q2 2025, AXT reported revenue of $18.0 million, down from $19.4 million in Q1 2025 and significantly below $27.9 million in Q2 2024, reflecting ongoing market softness and operational headwinds. The revenue mix included $3.6 million from indium phosphide substrates, $6.2 million from gallium arsenide, $1.5 million from germanium, and $6.7 million from consolidated raw material ventures. Asia Pacific accounted for 90% of revenue, reinforcing the company’s geographic concentration.
Gross margins improved sharply to 8.2% on a non-GAAP basis, up from a negative 6.1% in Q1 2025, driven by manufacturing process improvements and yield enhancements. Operating expenses were effectively managed, down to $7.6 million non-GAAP from $8.5 million in Q1, contributing to a non-GAAP operating loss reduction to $6.1 million from $9.6 million. The net loss narrowed to $6.4 million non-GAAP, or $0.15 per share, compared to $8.2 million in Q1. Inventory levels were modestly reduced to $80.1 million, reflecting ongoing efforts to optimize working capital.
- Revenue Headwinds from Export Permits: Approximately half of the revenue shortfall was attributed to slower gallium arsenide export permit approvals, delaying shipments outside China.
- Margin Recovery via Operational Focus: Yield improvements and efficiency gains in gallium arsenide manufacturing drove meaningful gross margin progress.
- Segment Dynamics: Indium phosphide revenue nearly doubled in China, fueled by AI and data center demand, while germanium sales grew in satellite solar cells but face margin pressures from raw material costs.
This quarter’s financial results underscore the tension between external geopolitical headwinds and internal operational improvements, setting the stage for potential sequential recovery if permit flows normalize.
Executive Commentary
"Our substrate revenue increased in Q2 from the prior quarter, though the increase was less than we had expected as a result of longer processing times for gallium arsenide export permits, coupled with some sluggishness in the demand environment in China, which also affected our raw material business."
Morris Young, Chief Executive Officer
"We continue to be highly focused on driving continued improvement, including further recovery in Q3. Moving to operating expenses, given the difficult climate, we have been working hard to hold OPEX down."
Gary Fisher, Chief Financial Officer
Strategic Positioning
1. Navigating Export Permit Challenges
China’s trade restrictions on gallium arsenide and indium phosphide, imposed in 2023 and 2025 respectively, require export permits for each order, introducing significant delays. These permit bottlenecks directly impacted AXT’s ability to fulfill international orders, causing revenue shortfalls. However, recent permit approval pace improvements, especially in July, signal a gradual easing. Management is cautiously optimistic about returning to more normalized export flows, which is critical for unlocking backlog shipments exceeding $10 million.
2. Capitalizing on AI and Data Center Growth in China
AXT is benefiting from increased domestic demand for indium phosphide substrates driven by AI-related applications and data center optical interconnectivity. China’s strategic push to develop indigenous sources for lasers and silicon photonics aligns with AXT’s product portfolio, particularly its low etch pit density (EPD) material which is favored for high-speed devices. The company expects indium phosphide revenue growth of 30% or more in Q3, reflecting the expanding market opportunity.
3. Operational Excellence Driving Margin Recovery
Focused efforts on manufacturing yield and process efficiency, particularly in gallium arsenide production, have enabled a significant gross margin rebound from negative territory to over 8%. This operational discipline is a key pillar in AXT’s strategy to return to profitability amid challenging market conditions and pricing pressures in segments like germanium.
4. Selective Approach to Germanium Segment
Germanium substrate sales, mainly for satellite solar cells, showed some growth but remain constrained by high raw material costs and export permit difficulties. AXT is taking a cautious stance, prioritizing margin preservation over volume growth in this price-sensitive segment, anticipating lower sales in the near term.
5. Maintaining IPO Progress Amid Geopolitical Uncertainties
The company’s subsidiary Tongmei continues its application process for listing on the Shanghai STAR Market. Despite a more selective IPO environment and geopolitical tensions, Tongmei remains a strong IPO candidate in China. This listing could provide strategic capital and visibility, supporting AXT’s long-term growth ambitions.
Key Considerations
AXT’s Q2 results reflect the complex interplay of geopolitical restrictions, operational execution, and emerging market dynamics. Investors should weigh the following factors:
