Bank of America Taps Aixtron as a Major AI Growth Catalyst for 2026

Bank of America has spotlighted Aixtron (ETR:AIXA), a German supplier of chip manufacturing systems, as its top small- and mid-cap pick for next year. The firm's upbeat outlook hinges on Aixtron's position supplying the crucial epitaxy deposition technology behind components powering AI-driven data centers.

Aixtron's technology is fundamental for the production of materials like gallium nitride (GaN), optoelectronics, and silicon photonics, all of which underpin faster and more efficient data transfer in a world where compute intensity keeps climbing. Bank of America's analysts describe Aixtron as providing the "picks and shovels" critical to the AI supply chain, tying the company to multiple fast-growing end markets.

Recent quarters have seen a rebound in optoelectronics demand led by data centers, where silicon photonics is rapidly becoming the go-to solution for enhanced connectivity. Around two-thirds of Aixtron's optoelectronics revenue in Q3 came from this sector, and BofA forecasts another strong quarter following into 2026, as adoption of silicon photonics spreads.

Looking further out, gallium nitride is pegged as a game changer from 2027, especially with the shift toward 800V high-voltage data center architectures aimed at handling AI's increasing power needs. GaN technology plays a key role in boosting power efficiency and density inside server racks. BofA projects a 44% boost in Aixtron's GaN revenue in 2027, fueled by NVIDIA's recent 800V Rubin Ultra server launch, with orders kicking in from late 2026.

According to the analysts, Aixtron commands around 90% market share in GaN epitaxy, positioning it strongly to remain the dominant supplier as broader GaN adoption gains steam. The company's tool performance and throughput are deemed critical, helping it maintain leadership in this niche amid rising AI-related demand.

Bank of America reaffirmed its Buy rating on Aixtron with a €25.10 price target. The valuation reflects the company's expanding footprint in AI-driven data center applications and an expected EBITDA growth rate that should outpace industry peers over the medium term.

As AI workloads push data centers to rethink their architectures and suppliers, Aixtron stands out as a key enabler for next-gen technologies like silicon photonics and GaN devices. Their dominance in these specialty areas offers a unique angle on how AI hardware supply chains are evolving beyond the usual chipmakers.

With Q4 results anticipated to show sustained momentum, the next year will be an interesting test of how Aixtron capitalizes on AI's infrastructure demands and whether other players can challenge its foothold in epitaxy tools.
