Geopolitical Shock Deepens Aixtron's Correction as Investors Await Dual Earnings Catalysts
Published on 07/13/2026 at 17:22 | Redaktion boerse-global.de
A sharp spike in oil prices triggered by escalating military strikes in the Middle East is sending fresh shockwaves through technology stocks, dragging Aixtron deeper into a correction that has already erased roughly a quarter of its value in the past month. Brent crude surged more than 4% to around $79 a barrel after reports that the US military launched a fourth wave of attacks against targets in Iran, stoking inflation fears that hit interest-rate-sensitive growth names particularly hard. Aixtron shares slid 3.37% on the session to €42.42, extending a 30-day slide of 25.29% that has brought the stock within 32% of its 52-week high of €62.68 reached on June 18.
The sell-off stands in stark contrast to the company’s year-to-date performance, which still shows an extraordinary gain of 116.70% — and on a 12-month horizon the equity has more than doubled, climbing 176.83% from its September 2025 trough of €12.02. The divergence between macro-driven price action and underlying fundamental momentum defines the fragile mood around Aixtron. The broader chip industry is booming: Taiwan Semiconductor Manufacturing Co. posted second-quarter revenue of 1.27 trillion Taiwanese dollars, up 36% year-on-year, with June alone rising 68%. TSMC’s CEO told reporters that demand for advanced 3-nanometer chips will outstrip supply for years. Further underscoring the sector’s health, Aehr Test Systems announced a record $41 million order for AI processors and silicon photonics, and German automakers warned of an impending chip shortage as AI applications soak up capacity. TSMC itself plans to invest roughly $56 billion in new capacity in 2026.
For Aixtron, a supplier of deposition equipment for compound semiconductors such as silicon carbide (SiC) and gallium nitride (GaN), this environment would normally be a tailwind — and it is in the optoelectronics segment that the most promising growth resides. The company’s G10-AsP platform has become a standard solution for high-speed data transmission in AI data centers, generating repeat orders from customers such as Lumentum, which recently bought G10-AsP MOCVD systems for its AI networking optics. The MIT Lincoln Laboratory has also placed an order for Hyperion systems aimed at GaN and 2D materials research. A strategic partnership with ROHM Semiconductor to scale GaN production via Aixtron’s G10-GaN platform reinforces the long-term narrative around energy-efficient power semiconductors for AI infrastructure, renewable energy, and electric mobility. Financially, the company sits on a solid foundation: equity accounted for 88% of the balance sheet at year-end 2025, and cash stood at €224.6 million.
Should investors sell immediately? Or is it worth buying Aixtron?
Yet the bull case is threatened by persistent weakness in the SiC power-electronics market. Aixtron itself has flagged a “soft market environment” for 2026, driven by significant overcapacity in SiC, and a recovery depends on better utilisation by customers and a normalisation of demand in the electric-vehicle space. This segment drag creates a clear divergence: the AI-powered optoelectronics business is firing, but SiC is still in a rut. The key question for investors is whether the former can fully compensate for the latter. Market capitalisation of €4.92 billion already reflects an ambitious valuation, and some analyst forecasts suggest earnings may decline in the coming years, adding to the risk.
The near-term calendar offers two distinct catalysts. On July 16, TSMC will publish detailed quarterly results that may provide read-throughs for equipment suppliers like Aixtron. Then on July 30, Aixtron itself releases its half-year report, which will offer the first concrete evidence of how the two technology segments are tracking. The company’s order intake and revenue breakdown by segment will be scrutinised for signs that optoelectronics momentum can offset the SiC headwind.
Chart-wise, the stock has fallen below its 50-day moving average of €52.85 and is hovering just under the 100-day average of €43.89. The 14-day relative strength index stands at 36.0, indicating oversold territory but not yet at extreme levels. With 30-day annualised volatility running above 80%, the ride is likely to remain bumpy until the earnings picture clarifies — whether the macro oil shock or the company’s own results will dominate the next leg of the trade remains an open question.
