Aixtron’s Rally Hits a 25-Year Peak as Analysts Clash Over the Next Chapter

Aixtron shares hit €49.67, highest since 2001, fueled by optoelectronics boom. Analysts split on valuation as Q1 sales slump but full-year guidance raised to €560M.

The German deposition equipment maker has stormed back to levels not seen since the dot-com era, with its shares touching €49.67 on Monday — the highest mark since 2001. The stock has now more than doubled this year, surging over 150% since January, and the momentum shows little sign of fading. But beneath the surface of this remarkable run lies a sharp divide among sell-side analysts about whether the valuation has run ahead of the fundamentals.

The Optoelectronics Boom Reshapes the Order Book

What’s driving the re-rating is a structural shift in Aixtron’s order intake. First-quarter orders hit €171.4 million, with nearly 70% coming from optoelectronics systems. Crucially, multiple clients placed multi-tool orders — a pattern that signals sustained demand rather than one-off purchases. The company’s G10-AsP platform has emerged as a go-to solution for photonic components used in AI data center communications, a market that is expanding rapidly as hyperscalers race to build out capacity.

The revenue picture for the opening quarter was far less impressive. Sales slumped to €59.4 million, roughly half the level seen a year earlier, and the company posted a net loss of nearly €22 million — a stark swing from the solid profit recorded in the same period of 2025. Management, however, has made clear that the real delivery wave starts in the second quarter, with a target of €110 million in revenue, nearly double the Q1 figure.

A Sharply Raised Full-Year Target

Buoyed by the order surge, the board has lifted its 2026 revenue guidance from €520 million to approximately €560 million, with a €30 million buffer built into the forecast. The power electronics segment remains a drag — SiC equipment sales are still sluggish, while GaN is stabilizing at a low level — but the optoelectronics boom is more than compensating.

The dividend proposal for the upcoming annual general meeting remains unchanged at €0.15 per share, matching last year’s payout.

Analysts Split on Where the Stock Goes From Here

The rally has sparked a fierce debate on the Street. Barclays downgraded Aixtron from Overweight to Equal Weight, with analyst Simon Coles raising his price target to €39 but arguing that the optoelectronics story is already priced in. He lifted his 2026 revenue estimates by 6% and 2027 forecasts by 15%, yet sees limited upside from current levels.

At the opposite end of the spectrum, Citigroup’s Andrew Gardiner maintains a Buy rating with a €55 target, having raised his earnings projections. He views the surge in investor confidence as sustainable, betting that the delivery ramp from the second quarter will validate the elevated valuation.

Deutsche Bank sits in the middle, sticking with Hold and a new €43 target. Analyst Michael Kuhn notes that capacity is fully utilized, leaving little room for further upward revisions to annual targets.

The gap between Barclays’ €39 and Citigroup’s €55 encapsulates the uncertainty. For now, the market is betting that the order book — and the AI-driven demand behind it — will continue to write the story.
