Infineon and Aixtron: The New World of Energy Efficiency
With the spectacular stock market success of Elon Musk’s SpaceX, the tech rally is gaining new momentum. The AI boom is developing its own ecosystem and is becoming a significantly stronger growth engine for suppliers like Infineon or Aixtron than many market participants had originally expected. While the public’s focus is mostly on AI processor manufacturers, providers of power semiconductors and power supply solutions are also increasingly benefiting. The Munich-based semiconductor manufacturer Infineon is one of Germany’s leading technology companies. However, the stock has already anticipated this development, having risen by a solid 120% over the past six months. This revaluation was driven primarily by rising earnings estimates and a noticeably more optimistic outlook from analysts. On the LSEG platform, a roughly 10% increase in revenue is expected, and the 2027 P/S ratio already stands at a remarkable 6.5. In our view, this valuation can only be justified if the increase in earnings per share actually lies in the range of 100% by 2029, but there are still three fiscal years to go before then. Consequently, Baader and mwb research have rated the share “Sell” with price targets around EUR 60. So far, the stock has just managed to hold above the EUR 80 mark. What a bull run!
The TecDAX-listed stock Aixtron has even surged by 240% over the past six months—reason enough for Deutsche Bank to take some wind out of its sails. The current rating is “Hold” with a price target of EUR 49. The optoelectronics boom remains the driving force, sparking new growth spurts at Aixtron. The rally in the stock is so pronounced because the entire industry has massively underestimated the scale of growth in photonic AI data processing. Analysts on the LSEG platform expect revenue to rise from EUR 556 million in 2025 to just under EUR 870 million in only three years. Currently, however, this still translates to a P/S ratio of 12. With prices around EUR 60, the stock is thus well overvalued. Sell!
A.H.T. Syngas: Decentralized Energy Transition with Significant Profit Potential
The energy transition is often associated with large-scale projects worth billions, but the actual transformation could take place much closer to the consumer in many places. The Dutch-German company A.H.T. Syngas Technology is putting this theory into practice. The company develops and operates decentralized energy systems that convert biogenic waste into valuable energy. The company has around three decades of engineering experience and now delivers its systems to multiple continents. At the heart of its operations is a patented dual-gasification technology that converts wood residues, sewage sludge, fermentation residues, or other waste materials into high-quality synthesis gas, which can then be used to generate electricity, heat, and, in the future, hydrogen as well. While many competitors rely on a limited number of raw material sources, A.H.T. deliberately focuses on waste materials, thereby bridging the gap between the circular economy, security of supply, and decarbonization.
The technological quality of the solution is particularly noteworthy. The so-called Twin-Fire process produces exceptionally clean synthesis gas with a high hydrogen content and can also process feedstocks that are often problematic for conventional systems. This allows A.H.T. to tap not only into the traditional bioenergy market but also into attractive future fields related to green molecules and industrial decarbonization. A German reference project already demonstrates the concept’s economic impact today. With an investment of around EUR 1.6 million, approximately EUR 600,000 in energy costs can be saved annually, while CO₂ emissions are reduced by around 1,500 tons. *Such real-world examples lend credibility to the technology and turn theoretical climate goals into tangible economic benefits. *
CEO Gero Ferges recently provided more detailed insights at the 19th International Investment Forum.
Strategically, the company is currently in an exciting phase of development. Until now, the focus has primarily been on plant sales; however, in the future, long-term operating and contracting models are expected to contribute significantly more to the revenue mix. This will generate recurring revenue from energy sales, heat supply, and potentially also from CO₂ and environmental certificates. Management expects this to improve the operating margin from around 10% to approximately 18% in the medium term. The move into hydrogen production from biomass also appears particularly promising. A newly developed and patented plant is expected to produce around 210 kg of hydrogen from just 1.7 tons of biomass per hour. In Germany, this could also generate attractive certificate revenues, further significantly improving profitability.
On the growth front, momentum is noticeably increasing. Revenue is expected to jump to over EUR 9 million by 2026, while revenues could rise to around EUR 23 million by 2028. At the same time, the operational turnaround is expected to succeed, and sustainable profitable growth is to be achieved again following a transition phase. AHT is seeing a particular uptick in Poland, where the partnership with INNOTEC Energy provides access to several concrete projects. Given the gradual phase-out of coal and significant biomass potential, the market there is developing into an attractive area for expansion. A.H.T. Syngas shares are currently trading at around EUR 2.98 – GBC Research assigns a “Buy” rating with a price target of EUR 8.50. If that is not substantial upside potential!
AMD: Well Positioned Through a Strategic Acquisition
The acquisition carousel is spinning again. US chip giant AMD has acquired the memory optimization startup Mext to address an increasingly critical issue in AI data centers: the shortage of memory and the rising costs of DRAMs. The purchase price was not officially disclosed, but market reports suggest a small double-digit million-dollar figure. This makes it clear that AMD is seeking technological additions in the field of artificial intelligence. Mext develops AI-based memory tiering technology that offloads rarely used data from expensive DRAM to significantly cheaper NAND flash and, via a predictive engine, returns it to fast memory promptly when needed. This expands the effectively usable memory capacity without the need to build additional physical DRAM infrastructure, while largely maintaining performance for AI applications.
From an investor’s perspective, the technology addresses a key bottleneck in the current AI cycle. While computing power scales significantly with new GPUs, available memory bandwidth grows much more slowly, making DRAM an increasingly limiting factor. For AMD, the acquisition fits into its strategy to position itself as a full-stack provider in the data center market, integrating not only CPUs and GPUs but also system and efficiency layers. Overall, the deal demonstrates that the AI cycle is increasingly expanding from pure computing power toward memory optimization and system efficiency. For AMD, this is another reason to push its current all-time high of around USD 550 even higher. A 500% gain in 14 months—formidable!
The tech rally continues, especially for blockbusters like AMD. However, investors are also increasingly focusing on suppliers that can do good business on the fringes of the AI boom. These include Infineon and Aixtron, which, however, are already well advanced in valuation terms. Also in the spotlight is A.H.T. Syngas with solutions for converting waste into syngas, an innovative concept bridging the circular economy and energy production.
