Aixtron's Photonics Pivot: How AI Data Centers Reshaped a German Chip Toolmaker's Fortunes
Published on 08/12/2026 at 15:31 | Redaktion boerse-global.de
The numbers tell two different stories about Aixtron right now, and both of them are true. On one side sits an income statement still healing from a painful product-mix transition. On the other stands an order book swelling with demand for the optical components that keep artificial intelligence infrastructure humming.
That tension played out visibly in the Herzogenrath-based equipment maker's shares on Tuesday, when the stock climbed 4.03 percent to 42.10 euros, extending a rally that has now run for seven straight sessions. The cumulative gain over that stretch: 13.34 percent, with the latest session adding 3.52 percent to reach 43.58 euros.
The Mix Shift Reshaping Everything
The clearest window into Aixtron's transformation comes from looking at what customers are actually buying. A year ago, power electronics built around gallium nitride and silicon carbide applications dominated the business, accounting for 71 percent of equipment revenue in the first half of 2025. That figure has now collapsed to roughly 22 percent.
The void has been filled by optoelectronics, which currently contributes around 54 percent of total equipment sales. The catalyst is unmistakable: AI data centers need optical data transmission at scale, and Aixtron's MOCVD systems for laser applications are in strong demand. CEO Felix Grawert has signaled that larger shipments of laser systems will begin in the third quarter of 2026.
Should investors sell immediately? Or is it worth buying Aixtron?
The pivot carries a cost. First-half revenue fell to 174.5 million euros from 249.9 million euros in the prior-year period, with the second quarter alone dropping to 115.1 million euros from 137.4 million euros. EBIT in Q2 slipped to 14.7 million euros from 23.6 million euros a year earlier. The company swung to a net profit of 19.15 million euros in the second quarter, a sharp reversal from the 21.9 million euro loss posted in Q1, though the half-year period result still lands at minus 2.8 million euros.
Orders Point Forward, Not Back
The order intake, however, tells a far more encouraging story. New business in the second quarter surged 81 percent to 214.5 million euros, lifting the order backlog to 456.9 million euros as of June 30 — a figure the company rounds to 457 million. That pipeline provides the foundation for management's confidence in the second half.
The cash flow picture adds another layer of reassurance. Free cash flow for the first half reached 162.1 million euros, more than double the 71.1 million euros recorded a year earlier, buoyed by substantial customer prepayments that are effectively co-financing the upcoming production ramp-up.
Management has confirmed its April-raised guidance for the full year: revenue of 560 million euros (plus or minus 30 million), an EBIT margin between 17 and 20 percent, and a gross margin of roughly 42 percent. The third quarter is expected to deliver a significant step-up to 180 million euros in sales, with a 20-million-euro swing either way.
Capacity, Capital, and the Analyst Divide
To handle the anticipated delivery wave, Aixtron is investing around 40 million euros in a new production site in Penang, Malaysia, where earthworks have already begun.
Institutional investors are taking notice. A voting rights notification published by Goldman Sachs points to ongoing repositioning among the company's shareholders. The stock's RSI of 55.3 suggests a technically neutral zone, leaving room for further upside if the fourth-quarter system deliveries proceed as planned.
Aixtron at a turning point? This analysis reveals what investors need to know now.
Analyst sentiment remains split, reflecting the gap between order momentum and recent operating metrics. Jefferies has reiterated its buy recommendation, and JPMorgan confirmed its overweight rating after reviewing the figures. DZ Bank and Berenberg, meanwhile, have held steady with "hold" ratings.
A Stock Still Climbing Back
The share price has been on a remarkable trajectory. From the 52-week low of 11.68 euros, the stock has more than tripled. It remains roughly 30 percent below its June peak of 62.68 euros — the secondary report puts the precise gap at 32.83 percent — but the year-to-date advance stands at an eye-popping 151.83 percent.
The central question for investors is whether the order backlog can translate into revenue and profit in the quarters ahead. The laser system deliveries slated for the third quarter will provide an early test. The backlog of 456.9 million euros offers the raw material; the optoelectronics division now has to convert it into results.
