AXT, Inc. (AXTI) Q3 2026 earnings review
AXT wafer sales jump 54%, and factory profit margins double
AXT, a maker of specialty semiconductor wafers for data center lasers, grew much faster than its own floor while factory margins expanded. Third-quarter revenue rose 54% from last quarter to $73 million, clearing the $66 million permitted-only floor as export permits arrived. Gross margin excluding one-offs reached 56%, up 11 percentage points in a single quarter, because chief executive Morris Young's factories shipped more large-diameter indium phosphide wafers.
| Revenue | $73.4M +163% from a year ago; +54% from Q2 |
|---|---|
| Gross margin, excluding one-offs | 56.1% 45.0% in Q2 and 22.4% a year ago |
| Profit per share, excluding one-offs | $0.41 planned $0.30–$0.32 |
| 2026 InP revenue opportunity | Raised to >4x up from >3x in Q2 and 2x at start of 2026 |
⚖️ Verdict: 🟢 Bullish
The story got better because AXT quadrupled its 2026 indium phosphide revenue opportunity through factory productivity and larger wafer sizes without needing heavy capital spending, while a $98 million jump in balance-sheet liabilities shows that customer prepayments arrived. One caution: past stock offerings increased the share count by 50% from a year ago while over $825 million in cash and investments sits on the balance sheet, and all factories remain subject to Chinese export controls.
The question now is whether the 56% gross margin and rapid shipment pace reflect a lasting shift to larger wafers for artificial intelligence data centers, or temporary shortage pricing as delayed orders clear. If the shift is lasting, fourth-quarter margins will stay above 50% and contracted obligations in the quarterly filing will top $150 million; if it is a temporary catch-up, orders and pricing will cool once backlog clears. The conference call outlook and the 10-Q contract footnote will tell.
🐂 Bull Case
Indium Phosphide Revenue Opportunity Quadrupled in 2026
AXT makes compound semiconductor wafers, notably indium phosphide (InP), a specialty material used in high-speed optical data center connections where standard silicon cannot perform. Chief executive Morris Young entered 2026 planning to double InP capacity and raised that target to triple last quarter. In the third quarter, revenue jumped 54.3% from the prior quarter to $73.4 million, beating the $66.0 million permitted-only floor.
Young said that "not only have we surpassed that goal but we have more than quadrupled our 2026 indium phosphide revenue opportunity through additional productivity gains and the expansion of our capabilities for high-value, large diameter products." By our math, holding other products flat at second-quarter levels puts InP sales near $56.5 million this quarter. That nearly reaches the prior $60 million year-end capacity target a full quarter early.
What to watch: the exact InP revenue dollar figure and updated fourth-quarter capacity run-rate on the conference call. A number above $55 million would confirm that factory productivity gains are lifting output without waiting for new buildings.
Factory Leverage Lifted Gross Margin Past 56%
Making crystal wafer substrates involves high fixed factory costs, so profitability swings widely with factory volume and product mix. Last quarter, management suggested gross margin excluding one-offs would stay near 45.0% in the third quarter. Instead, gross margin excluding one-offs jumped 11.1 percentage points from last quarter to 56.1%, up from 22.4% a year ago.
- Cost of revenue: 44.0% of sales, down 33.7 percentage points from a year ago and down 11.1 points from last quarter
- Selling and administrative costs: 11.9% of sales, down 10.8 percentage points from a year ago
- Research and development costs: 5.4% of sales, up 1.8 percentage points from a year ago to $3.9 million
Gross margin expanded because AXT shipped a richer mix of large-diameter wafers and spread its fixed factory overhead across 54.3% more revenue. That 11-point margin expansion drove operating profit excluding one-offs to $29.5 million, or 40.2% of sales, easily absorbing $1.2 million of higher-than-planned operating expenses.
What to watch: fourth-quarter gross margin outlook on the conference call. Holding above 50% as new factory equipment enters service would show that higher wafer prices and larger diameters outweigh new depreciation costs.
Customer Prepayments Jumped by Nearly $98 Million
Historically, AXT sold wafers on short-term orders with little visibility. This year, optical transceiver customers began signing multi-year supply deals with upfront cash deposits to lock in wafer supply. Following June agreements with Casela and Coherent, AXT signed a six-year capacity reservation with Lumentum in July requiring an initial $43.5 million deposit within 30 business days.
The third-quarter balance sheet shows those cash advances arrived. Accrued liabilities rose by $73.4 million from last quarter to $100.4 million, while other long-term liabilities climbed $24.4 million to $42.9 million. By our math, that combined $97.8 million increase captures the $43.5 million Lumentum deposit and the remaining $35.0 million of contracted advances from Coherent and Casela, alongside routine operating accruals.
What to watch: the exact contract liabilities and remaining performance obligations (RPO, the value of contracted future deliveries) in the quarterly filing. A figure above $150 million would confirm that Lumentum's multi-year commitment is legally binding revenue.
🐻 Bear Case
Share Offerings Diluted Shareholders by 50% While Cash Sits Idle
Management states that AXT is raising capital to fund its manufacturing expansion for artificial intelligence data centers. Across December 2025 and April 2026, the wafer maker issued nearly 17 million shares to raise almost $700 million in net cash. That pushed the diluted share count up 50.2% from a year ago to 65.9 million shares in the third quarter.
The balance sheet cuts against the claim that the expansion required this much equity. Total cash, restricted cash, and investments reached $825.9 million in the third quarter, up $77.0 million from June, while property, plant, and equipment rose by just $19.4 million. Because AXT quadrupled its 2026 InP revenue opportunity primarily through productivity gains and customer prepayments, hundreds of millions in raised cash remain parked in securities earning $5.9 million of quarterly interest.
What to watch: capital expenditure plans for 2027 on the conference call. Without a major new factory investment, the extra shares permanently reduce per-share earnings by a third in exchange for low-yielding interest income.
China Export Permits and Tongmei Redemptions Remain Live Risks
AXT conducts all of its manufacturing at three sites in China and owns stakes in more than ten Chinese raw-material suppliers. Since early 2025, China's Ministry of Commerce has required export permits for every indium phosphide shipment leaving the country. In the release, the company again warned that results depend on "the receipt of export permits for our indium phosphide substrates" and geopolitical tensions between China and the United States.
Separately, after subsidiary Tongmei withdrew its Shanghai listing application in July to pursue a Hong Kong listing, Chinese private equity investors gained the right to demand their money back. AXT flagged the risk of "the withdrawal, cancellations or requests for redemptions by private equity funds in China of their investments in Tongmei," which sit on the balance sheet at $42.3 million in redeemable noncontrolling interests.
What to watch: the geographic revenue table and Tongmei legal disclosures in the quarterly filing. Any permit freeze by Beijing would immediately halt shipments to international customers outside China.
Risks this quarter didn't answer
The earnings release only provides summary financial tables, leaving five standing questions and watch items unreadable until the conference call and the quarterly Form 10-Q filing.
- Product revenue breakdown: indium phosphide vs gallium arsenide and germanium sales are given on the conference call, not in the release.
- Order backlog and contracted RPO: management stopped sizing the InP backlog above $100 million last quarter, and RPO ($98.5 million in Q2) lives in the 10-Q footnotes.
- Permit-free China demand: sequential growth in domestic Chinese laser sales, which tests demand without export permit distortions, is disclosed in prepared call remarks.
- Operating cash flow and capital spending: the release omits a cash flow statement, though net cash and investments less debt rose by $88.8 million in Q3 by our math.
- Governance and legal updates: any changes to related-party joint venture transactions, the Tongmei Hong Kong listing timeline, or the shareholder lawsuit await the 10-Q.
💲 Other KPIs
Working capital grew much slower than sales in the third quarter. Inventories rose 7.6% from last quarter to $103.7 million, and accounts receivable — bills owed by customers — increased 8.2% to $39.7 million, while revenue jumped 54.3%. Shipping pre-built wafer stock as export permits cleared kept cash from being tied up in unsold goods.
Net factory assets rose 11.1%, or $19.4 million, from last quarter to $194.4 million, after rising $10.3 million in the second quarter and $2.8 million in the first. The step-up reflects equipment additions at Tongmei's Chinese facilities to support large-diameter indium phosphide wafer production.
Total operating expenses rose 15.8% from last quarter to $12.7 million ($11.7 million excluding stock-based pay, $1.2 million above the $10.5 million plan). Even so, fast revenue growth pushed operating expenses down to 17.3% of sales, compared with 23.0% last quarter and 26.3% a year ago.
🔮 Guidance
Raised. Chief executive Morris Young said AXT has now more than quadrupled its 2026 indium phosphide revenue opportunity, up from a goal to double it at the start of the year and triple it last quarter. It is the second raise this year (+1x in Q2, +1x in Q3), driven by factory productivity and larger wafer sizes. Quantitative fourth-quarter revenue and profit targets are given on the conference call, not in the release.
❓ Key Questions
What is the fourth-quarter permitted revenue floor and margin plan?
AXT issues its quarterly revenue floor and earnings outlook on the conference call rather than in the press release. After revenue reached $73.4 million and gross margin hit 56.1%, the fourth-quarter floor will show whether export permit approvals are keeping pace with factory output.
How much did indium phosphide and domestic China sales grow?
Holding other product lines flat implies about $56.5 million of indium phosphide sales in Q3. Investors need the exact product breakdown and the growth rate of domestic Chinese sales, which require no export permits and test underlying demand.
How much of the $97.8M liability jump is customer prepayments?
Combined accrued and other long-term liabilities rose by $97.8 million in Q3, when Lumentum's $43.5 million deposit and Coherent's $22.3 million advance were due. The 10-Q contract table will show how much entered deferred revenue and remaining performance obligations.
When will AXT deploy the remaining $753 million of net cash?
AXT holds $825.9 million in cash and investments against $72.5 million in short-term debt, yet quadrupled its 2026 InP opportunity mainly through productivity gains and customer deposits. Management has not explained why it needed to dilute shareholders by 50%.
