Berenberg has adjusted its stance on Aixtron SE, cutting the recommendation on the German equipment maker to Hold from Buy even as it lifted the firm's price target to EUR42.00 from EUR31.00. The change reflects the broker's view that the market now broadly understands the bottleneck dynamics in the optoelectronics supply chain that benefit Aixtron, after the stock surged 195% year-to-date.
The research house upgraded its underlying financial assumptions for Aixtron, increasing sales estimates by 9-13% and raising EBIT forecasts by 20-24% for 2026-2027. Those revisions stem from a more optimistic read on demand for the optoelectronics tools that Aixtron supplies.
Berenberg expects the company's optoelectronics revenues to more than double to EUR243m in 2026, and it models a compound annual growth rate of 29% for the 2026-28 period. The broker noted heightened market attention on the segment, observing that Google searches for terms such as "optical transceivers" and "indium phosphide" have spiked and that shares across the optoelectronics value chain have climbed rapidly.
Despite the bullish demand outlook, Berenberg flagged structural limits that could restrain further upside. The firm points to an estimated USD18bn market for datacom transceivers that is today underpinned by a compound substrates market worth less than USD1bn. That disparity suggests the installed base of epitaxial equipment addressing this market remains small relative to end-market size.
On that basis, Berenberg argued that anticipated growth from Aixtron and its customers - including current tool investments - may be adequate to satisfy end-market needs. If true, this dynamic could cap additional upward momentum in the company’s earnings and limit share-price appreciation beyond what has already occurred.
Market pricing supports the broker's caution. Aixtron shares finished at EUR51.40 on Monday on XETRA. After the year-to-date advance, the stock trades at approximately 7.2x FY27 EV/sales and 29.9x FY27 EV/EBIT - multiples Berenberg describes as full and reflective of priced-in growth expectations.
Berenberg's revised forecasts sit broadly in line with consensus estimates for fiscal years 2026-28. The firm reiterated that while Aixtron remains well positioned to benefit from wider adoption of compound semiconductors, the scale of current customer tool spending could be sufficient to meet the near-term needs of the end markets the company serves.
