The sharp rally reflects growing investor optimism around AXT’s exposure to AI infrastructure and co-packaged optics. As AI data centers expand, demand for high-performance optical components is increasing, creating a favorable growth opportunity for the company. Long-term customer commitments and a strong backlog provide greater visibility into future demand, while aggressive InP capacity expansion could help AXT meet rising requirements for indium phosphide-based components and capture a larger share of the expanding market.
AXT has also outperformed several semiconductor peers. Applied Optoelectronics (AAOI - Free Report) , GlobalFoundries (GFS - Free Report) and Lam Research (LRCX - Free Report) have gained 16.7%, 7.8% and 4.2%, respectively, over the past month. While Applied Optoelectronics, Lam Research and GlobalFoundries have also benefited from favorable semiconductor and technology trends, AXT’s recent performance highlights stronger investor interest in its AI-related optical component opportunity.
AXT’s One-Month Performance

After such a strong gain in a short span, investors may wonder whether to take profits or stay invested for further upside. Let’s examine AXT’s key growth drivers and risks to determine whether the stock is a buy, sell or hold at current levels.
AI Data-Center Demand Positions AXTI for Multiyear InP Growth
AXTI is increasingly well positioned to benefit from the rapid expansion of optical connectivity in AI data centers, where indium phosphide (InP) substrates support high-speed optical links through InP-based lasers and detectors. Management expects near-term demand to be driven by the industry's migration toward 800G and 1.6T transceiver modules, while the longer-term shift toward near-packaged and co-packaged optics could extend the InP demand cycle as hyperscalers deploy increasingly GPU-dense architectures and require faster, lower-power photonics.
Importantly, this opportunity is already translating into stronger financial performance. AXT generated record InP revenues of $30.7 million in the second quarter of 2026, primarily driven by data-center applications. Its InP revenue opportunity is on track to more than triple by the end of 2026, with further significant expansion expected in 2027. Demand continues to exceed supply, with the company's InP backlog surpassing $100 million. AXT is also ahead of schedule in its plan to double InP capacity in 2026, while new crystal-growing furnace designs and manufacturing productivity improvements are increasing output. Customer migration toward larger-diameter substrates and higher-value products is also supporting favorable pricing.
The growth opportunity is further supported by increasing customer commitments. AXT recently entered long-term agreements with Casela, Coherent and Lumentum, including capacity reservations, supply commitments and customer prepayments. The Coherent agreement covers the development and supply of 6-inch InP substrates and calls for capacity expansion through 2028, while AXT plans to double its InP capacity again in 2027. These developments provide greater visibility into future demand and reinforce management's view that additional capacity is necessary to meet customer requirements.
Positive Analyst Sentiment for AXTI
Analyst sentiment toward AXT remains favorable, with the Zacks Consensus Estimate projecting 2026 revenues to surge 146.4% year over year.
The consensus mark for 2026 earnings is pegged at 86 cents per share and remains stable over the past 30-day and 60-day periods. More importantly, the estimate represents a 309.8% year-over-year increase, pointing to expectations for a significant improvement in earnings. For investors, the combination of sharply higher revenues and earnings expectations provides fundamental support for AXT’s growth outlook.

China Dependence and Competition Weigh on AXT
AXT’s heavy dependence on China remains a significant and persistent challenge. All of its wafer substrates are manufactured in China, and most raw materials are sourced there, leaving production and supply continuity exposed to China-specific regulatory, environmental and geopolitical risks. More importantly, China’s export controls on InP require government permits, which the company calls its “most significant challenge.” Changing tariffs and retaliatory measures could force AXT to raise prices or make operational changes, potentially causing customer losses and materially harming its business, financial condition and results of operations.
Competition remains a key concern for AXT. The company competes with Sumitomo, JX, Freiberger, Umicore, Vital and CCTC, while Sumitomo and JX also compete directly in InP. Companies including Qorvo and Skyworks are pursuing alternative materials for GaAs applications. These rivals may have greater market share, better recognition and stronger financial and technical resources.
AXTI Stock Looks Overvalued
AXTI stock appears overvalued at present, as reflected by its Value Score of F.
Its trailing 12-month price/sales (P/S) ratio of 42.51X stands well above the Electronics – Semiconductors industry’s average of 16.6X, indicating that investors are paying a significant premium for the company’s sales compared with its industry peers. Applied Optoelectronics, GlobalFoundries and Lam Research trade at P/S multiples of 17.81X, 3.9X and 18.05X, respectively.

Conclusion: Stay on Hold for the Time Being
AXTI’s exposure to AI data centers and growing demand for InP substrates provide a strong foundation for future growth. The company’s expanding capacity, solid backlog and long-term customer agreements further strengthen its prospects. Still, the stock’s premium valuation, dependence on China and competitive pressures create meaningful risks.
Given its attractive growth prospects, investors should stay on Hold and allow the company’s fundamentals to support further gains.
