AXT Inc. (AXTI) is a manufacturer of compound semiconductor substrates — the specialized wafers used in applications like fiber optics, 5G infrastructure, LEDs, and solar cells. After two strong years in 2021–2022, the company hit a prolonged rough patch driven by oversupply and weak demand, posting operating and net losses from 2023 through its full fiscal year 2025. Revenue shrank significantly from a peak of $141M in 2022 to just $88M in 2025. However, the most recent quarterly data (Q2 2026, the freshest available) tells a dramatically different story: revenue surged, gross margins recovered sharply to ~45%, and the company swung to meaningful profitability. The balance sheet remains conservative — low debt, a solid current ratio — and capital spending has fallen substantially from its heavy investment phase. If the Q2 2026 trend holds, AXT may be turning a genuine corner after a painful three-year downturn.
Snapshot & Big Picture
AXT designs and produces indium phosphide (InP), gallium arsenide (GaAs), and germanium (Ge) substrates, selling into high-tech end markets that are sensitive to inventory cycles. The 2021–2022 boom reflected strong data center and 5G buildout demand; the subsequent bust from 2023 to 2025 reflected customers burning off excess inventory and reduced capital spending across the supply chain. The company's revenue fell roughly 37% from its 2022 peak to 2025, and it burned cash at the operating level for three consecutive years. The silver lining has been a disciplined balance sheet — minimal debt and a current ratio comfortably above 2x throughout — which gave the company room to weather the cycle.
| Fiscal Year | Revenue | Gross Margin | Operating Margin | Net Margin |
|---|---|---|---|---|
| 2016 | $81.3M | 32.4% | 7.9% | 6.9% |
| 2017 | $98.7M | 34.9% | 12.8% | 10.3% |

Latest Quarter Snapshot (Q2 2026 — Most Current Data)
The most recent filing covers the quarter ended June 30, 2026, and it represents a sharp reversal from the annual trend. Revenue for the quarter came in at $47.6M — which, if annualized, would imply a run rate well above $180M, though single-quarter extrapolation should be treated with caution. More telling is the margin recovery: gross margin hit ~44.9%, operating margin reached ~21.9%, and net margin landed at ~23.4%. EBITDA for the quarter alone was $12.9M, more than the full-year EBITDA loss recorded in 2025. The current ratio improved dramatically to 4.77, and debt-to-equity remains negligible at 0.006. Capital expenditures were just $1.4M for the quarter (~2.9% of revenue), the lightest spending quarter in years. This data is more current than the annual figures and suggests the cyclical recovery AXT's management had been anticipating may now be materializing in earnest.
Profitability
The profitability story across the full annual record is one of cyclicality. AXT operated profitably from 2016 through 2018, dipped to a small net loss in 2019, recovered through the pandemic-era demand surge in 2020–2022, then suffered its worst sustained downturn from 2023 to 2025. Gross margins collapsed from ~37% at the 2022 peak to just 12.7% in fiscal 2025 — an unusually low figure that reflects both weak pricing power and the fixed-cost burden of underutilized manufacturing capacity. Operating losses widened to -24.9% of revenue in 2025 despite revenue being modestly higher than the trough year of 2023. The Q2 2026 quarter, however, shows gross margin snapping back to nearly 45% — above any annual figure in the ten-year record — suggesting that when volume returns to AXT's fabs, the underlying operating leverage is substantial and margin recovery can be rapid.
Financial Health & Capital Expenditures
AXT's balance sheet has remained a relative strength throughout the cycle. The current ratio has stayed above 2x even during the loss years, reaching 4.77 in Q2 2026. Debt-to-equity is essentially negligible — below 0.02 across all periods where it was reported (it was not available in the 10-K filings for 2016 through 2022, so those figures are omitted). The company entered its downturn without meaningful leverage, which reduced the risk of financial distress.
Capital expenditure trends are an important part of the AXT story. The company invested heavily during its growth phase — capex-to-revenue ratios of 20–40% from 2017 through 2022 as it expanded substrate manufacturing capacity. That investment phase has clearly ended. Annual capex dropped from $28.5M (2022) to $10.5M (2023) to $5.8M (2024) and $6.0M (2025), with the capex-to-revenue ratio falling to roughly 6–7%. In Q2 2026, quarterly capex was only $1.4M (~2.9% of revenue), the lowest intensity in the dataset. This signals that the company is no longer in an aggressive build-out phase and is instead harvesting the capacity already installed — a dynamic that should support free cash flow improvement as revenue recovers.

The 10-year CAGR is not available because the SEC filing history in the provided dataset does not extend back far enough to construct a 10-year trailing window from fiscal year 2025. The 3-year CAGR of -14.5% reflects the severe revenue contraction from the 2022 peak through the trough cycle. The 5-year CAGR of -1.5% is nearly flat, illustrating that the boom-and-bust cycle has largely cancelled out over the medium term — AXT in 2025 was generating nearly the same revenue it was in 2020, just with much weaker margins. The key question for investors is whether Q2 2026's volume surge represents a durable re-acceleration or a temporary restocking event.
