AXT Q3 2026 Earnings: Indium Phosphide Demand Drives a Profit Turnaround

AXT (Nasdaq: AXTI) reported Q3 2026 revenue of $73.4 million, up 162% from $28.0 million a year earlier, while GAAP diluted EPS improved to $0.39 from a loss of $0.04. Record revenue, stronger gross margin, and operating leverage produced a sharp profit turnaround, with management identifying indium phosphide demand as the main growth driver.

Core Earnings Data

Revenue also increased 54% sequentially from $47.6 million in Q2 2026. GAAP gross margin reached 56.0%, compared with 44.9% in the preceding quarter and 22.3% a year earlier.

The combination of higher revenue and a 33.7-percentage-point year-over-year expansion in gross margin moved AXT from operating and net losses to substantial profits. Non-GAAP results were only modestly higher than GAAP results because the principal adjustment was $1.1 million of stock-based compensation.

Indium Phosphide Demand and Margin Expansion Drove the Turnaround

Management attributed the record revenue primarily to exceptionally strong customer demand for indium phosphide material. AXT did not disclose product-level revenue, so the precise contribution from indium phosphide relative to gallium arsenide and germanium cannot be quantified from the release.

AXT also cited productivity gains and expanded capabilities for higher-value, large-diameter products. These developments coincided with the rise in GAAP gross margin to 56.0%, although the company did not provide a numerical bridge showing how demand, product mix, productivity, and other factors individually affected the margin.

Operating expenses increased to $12.7 million from $7.3 million, or approximately 72%, but revenue grew considerably faster. As a result, the operating margin improved to approximately 38.7% from negative 4.0% a year earlier.

Profitability and Balance Sheet

Net interest income provided an additional earnings benefit. AXT recorded $5.9 million of net interest income, compared with $395,000 of net interest expense in Q3 2025, representing a year-over-year swing of approximately $6.3 million before taxes.

The balance sheet expanded substantially between December 31, 2025, and September 30, 2026. Cash and cash equivalents increased to $485.5 million from $120.3 million. Short- and long-term investments totaled another $299.2 million, bringing combined cash and investments, excluding restricted cash, to approximately $784.7 million.

Current liabilities also increased to $190.9 million from $90.5 million. Within that total, short-term loans rose to $72.5 million from $62.8 million, while accrued liabilities increased to $100.4 million from $14.8 million. Inventory reached $103.7 million, up from $81.7 million at year-end 2025.

The weighted-average diluted share count was 65.9 million, approximately 50% above 43.8 million in the prior-year quarter. This higher share base reduced the amount of corporate profit represented by each share compared with what EPS would have been at the earlier share count.

Management View

CEO Morris Young said AXT entered 2026 intending to double its indium phosphide capacity and has since surpassed that goal. He added that productivity gains and expanded large-diameter product capabilities have more than quadrupled the company’s 2026 indium phosphide revenue opportunity. That statement describes potential opportunity and capacity rather than reported revenue or formal quantitative guidance.

Management’s emphasis remains on scaling production and supporting customers as their demand increases. Execution, production yields, and the ability to translate expanded capacity into sustained sales and margins are therefore central to evaluating subsequent quarters.

Recent Insider Transactions

The supplied six-month insider summary shows 103,165 shares purchased across six transactions and 272,336 shares sold across nine transactions, resulting in net sales of 169,171 shares. Among the latest 10 reported transactions, six were sales with an aggregate reported value of approximately $5.77 million; the remaining entries were one stock gift and three stock awards.

These records describe the transactions but do not establish the insiders’ reasons for buying, selling, gifting, or receiving shares.

Risks Investors Need to Watch

• Dependence on indium phosphide demand: Management identified this product category as the main revenue driver. Any moderation in customer demand could affect both growth and manufacturing utilization.
• Margin and production execution: Sustaining a 56.0% gross margin may depend on productivity, product yields, capacity utilization, and continued demand for higher-value, large-diameter products.
• Export permits and geopolitical exposure: AXT identified the receipt of export permits for indium phosphide substrates and tensions between China and the United States as factors that could affect operations and sales.
• Higher diluted share count: The approximately 50% year-over-year increase in diluted weighted-average shares can limit EPS growth relative to the growth in total net income.
• Growth in accrued liabilities: Accrued liabilities rose to $100.4 million from $14.8 million at year-end 2025. The release did not explain the increase, making its future working-capital and cash effects an item to monitor.

Summary

AXT’s Q3 2026 results reflected a major earnings turnaround as indium phosphide demand, productivity gains, and higher-value product capabilities supported record revenue and substantial gross-margin expansion. The next points to monitor are whether demand and margins remain durable, how effectively AXT converts expanded capacity into sales, and how export-permit exposure, rising liabilities, and the higher share count affect future per-share performance.
