** Aixtron AIXGn.DE stock rises around 7% after Jefferies upgraded the German semiconductor equipment supplier to "buy" from "hold", citing its role as a largely overlooked AI growth story and a strengthening optoelectronics outlook
** The broker highlights strong spending from cloud service providers and a pull-forward of capital expenditure by key data communication customers, reinforcing Aixtron's revenue outlook for 2026 and 2027
** It sees an attractive mid-term growth opportunity in Gallium Nitride (GaN) chips for AI data centres, as Aixtron holds a 90% market share in Metal-Organic Chemical Vapour Deposition (MOCVD) tools used in their production
** Jefferies notes that the outlook for Silicon Carbide (SiC) is now "largely derisked," and believes there is "ample legroom for multiple expansion" in the stock's valuation from trough earnings
** Aixtron stock is on a 21-month high
