Forget tech stocks! Siemens Energy, A.H.T. Syngas, and Linde are the secret money-making machines

Siemens Energy – From problem child to beneficiary of the energy transition

Siemens Energy closed the first quarter of 2026 with unexpectedly good figures. Revenue increased noticeably, but above all, order intake skyrocketed to just under EUR 18 billion, driven by continued strong demand for gas turbines and grid technology. The wind power subsidiary Gamesa, which has been in crisis for a long time, is also showing initial progress. The operating loss shrank significantly, and management is confident that the division will at least break even in the course of the year. The total order backlog now stands at a historic EUR 146 billion, providing exceptional planning security for the coming years.

The group is investing heavily in expanding its US capacity. USD 1 billion is being poured into new factories for transformers and turbine components, a strategically smart move. The US is currently the hottest electricity market in the world, driven by the rapidly growing energy appetite of data centers. Around 29% of orders already come from this sector. Internally, the future of Gamesa remains a topic of discussion. While activist investors are calling for a spin-off, the management board is focusing on stabilization and wants to lead the subsidiary to profitability by 2028. The upcoming annual general meeting should provide clarity on this issue.

The share price has developed rapidly in recent months. Analysts see further upside potential, but also highlight the now high valuation. With a price-to-earnings ratio of over 75, a lot of optimism is already priced in. Management itself is targeting a margin of up to 16% by 2028 and plans to reward shareholders with dividends and a billion-euro buyback program. The decisive factor will be whether Gamesa's operational recovery is truly sustainable and whether the high order backlog can be translated into margins as expected. The stock is currently trading at EUR 165.90.

A.H.T. Syngas – From plant manufacturer to energy supplier

Imagine a plant that takes wood waste, sewage sludge, or fermentation residues and turns them into a gas that can be burned without any problems instead of natural gas. That is exactly what A.H.T. Syngas Technology does. The Dutch company has been building such plants for years, primarily for customers in Japan and Europe. The technology behind it is not rocket science, but it is more sophisticated than a simple biogas plant. In a so-called double-fire gasifier, the residues are heated in the absence of air until they break down into hydrogen and carbon monoxide. The resulting gas mixture, known to experts as synthesis gas, can then either be converted directly into electricity or used as a process gas in industry. This is particularly interesting for companies with a lot of wood waste or municipalities with sewage sludge problems: they save disposal costs and obtain energy at the same time.

In mid-February, there was a report that should not be overlooked. A research project funded by the German Federal Ministry of Economics on hydrogen production from biomass was successfully completed. At first glance, this sounds like typical research funding, but the results are impressive. The technology can produce hydrogen from wood residues at costs lower than those of conventional electrolysis processes. And because the process binds CO2 instead of releasing it, it could also result in certificates for emissions trading later on. For a company of this size, this is quite an advance and a clear signal that the development work of recent years is bearing fruit.

If you are wondering where this is going, A.H.T. is currently in the process of revamping its business model. In the past, they mainly sold plants, one-off deals, so to speak. Now they plan to operate the plants themselves and supply energy, which will generate recurring revenue in the long term. This is a smart move, because the market for synthesis gas is growing rapidly. Estimates suggest that it will double by 2035.
Industrial companies need to decarbonize their production, and municipal utilities are looking for solutions for green district heating. If A.H.T. succeeds in translating its technology into ongoing projects now, it could turn from a niche story into a real growth company. In any case, the financing for this is secured. The share is currently trading at EUR 4.40.

Linde – Solid growth and strategic realignment

Linde closed the 2025 financial year with solid revenue growth of 3% to USD 34 billion. Adjusted earnings per share rose by 6% to USD 16.46, while operating cash flow reached a new record high of USD 10.4 billion. Despite a challenging industrial environment, the industrial gas giant was able to increase its operating margin to 29.8%. The billion-dollar project backlog remained constant at USD 10 billion, ensuring long-term planning reliability. In the fourth quarter, Linde slightly exceeded expectations with adjusted earnings per share of USD 4.20, even though special items temporarily weighed on reported net income.

Management is cautiously optimistic about 2026. The forecast for adjusted earnings per share is between USD 17.40 and USD 17.90, which corresponds to an increase of 6-9%. Linde is benefiting from increasingly diversified demand. In addition to traditional industrial customers, growth is being driven primarily by the semiconductor industry and the business with specialty gases for aerospace applications. With CEO Sanjiv Lamba taking over as Chairman of the Board at the end of January, management structures were also streamlined, a clear commitment to operational efficiency and strategic continuity.

Analysts responded overwhelmingly positively to this development. The average price target is around USD 515, which corresponds to upside potential of just over 3%. Firms such as Berenberg, Bernstein, and Citigroup have recently raised their price targets to up to USD 545 and continue to recommend buying. Only JPMorgan was more cautious, downgrading the stock to "Neutral." Overall, however, optimism prevails. Linde combines stable cash flows with high-growth future fields such as hydrogen and electronics, a combination that will keep the stock interesting in 2026. The stock is currently trading at USD 498.19.

While the AI boom and the energy transition are shaking up the markets, three German companies are showing the way forward. Siemens Energy has transformed itself from a company in need of restructuring to a sought-after turbine manufacturer for the energy transition. Niche supplier A.H.T. Syngas Technology turns wood waste into valuable syngas and is revolutionizing its business model. Meanwhile, industrial giant Linde is securing key positions in the global LNG market with record cash flows. This trio proves that the hidden gems of the energy transition are not just plugged into the power grid.
