Riber should not be bought because the bullish claims about it outrun its financial statements. Reaching €120 million in sales this year looks impossible when there is not even guidance yet. Bulls cite 19 orders for the ROSI 2 platform, but only two have been reported, and the annual report says ROSI 2 is still in the design phase. The stock's 30% drop shows fundamental reality reasserting itself like gravity. x.com x.com x.com x.com
Riber's share price has more than quadrupled, far beyond a business that may at most roughly double revenue by 2030. MBE is no longer a strict duopoly with Veeco since DCA Instruments launched a 300mm platform, Microsoft Quantum as a core buyer lacks evidence, and an Aehr comparison ignores Riber's lumpy equipment sales and ~25% services. ROSIE is the only real re-rating trigger, but Veeco has the stronger 300mm partner in imec, and sputtering and MOCVD threaten MBE. x.com
Riber's quantum and photonics exposure keeps building: a second ROSIE system is expected to be delivered shortly to a leading US quantum computing player, and business development for its photonics BTO/STO products has drawn strong interest. It forms an MBE duopoly with Veeco, which was recently re-rated heavily. x.com
Riber could become a steady compounder if foundry orders arrive, though the stock has run past fundamentals and rivals may cap its market. Its MBE order from QD Laser is bullish, as MBE is more precise for quantum-dot epitaxy, but ETRI researchers showed MOCVD makes QD lasers cheaper with better yield, and Riber has no MOCVD hedge. If TSMC, Intel or Samsung adopt Veeco and imec's 300mm BTO process over ROSIE 2, Riber is boxed into a niche, so it needs a firm ROSIE 2 order from one by Q4 2026. … Show more
Riber's 25% share price drop reflects sentiment, not the business, so the bullish thesis is intact. Much of the slide is collateral damage from IQE's meltdown and broader sector cooling, magnified by thin small-cap liquidity. Riber is the global leader in molecular beam epitaxy, order visibility stays very high as chipmaking shifts to GaN and InP, and it supplies upstream enablers like IQE and Soitec. No other upstream semiconductor play offers this technical edge at such a lean market cap. … Show more
Riber is a long-term quantum bet: it supplies equipment that Microsoft uses for quantum computing, which should pay off well if quantum becomes real over a five-year hold. Material orders are unlikely to inflect soon, so the stock will probably be highly volatile. This view comes with limited familiarity with the company. x.com
