Verbio, E.ON, and A.H.T. Syngas: Market Leaders and Challengers

Verbio: Tax Credits Drive Growth in North America

Verbio, an integrated bioenergy producer, uses regional agricultural raw materials and residues to produce biodiesel, bioethanol, and biomethane. The circular economy model ferments the resulting distillers’ grains into biomethane, while the organic residues are returned to agriculture as biofertilizer. In addition, monetizing emissions savings supplements revenue from the core business. To benefit from the extensive US tax credits under the Inflation Reduction Act, Verbio is systematically expanding its production capacity in the North American market.

The company is retrofitting the South Bend biorefinery in Indiana at a cost of approximately USD 230 million to produce up to 250,000 metric tons of bioethanol and approximately 850,000 MWh of biomethane annually, following the commissioning originally scheduled for 2026. According to the latest annual report, Verbio is continuing its investments in South Bend in stages. In the first nine months of fiscal year 2025/26, Verbio increased biomethane production by 20.2% to 1,040 GWh, driven by the ramp-up of the Nevada plant. In the most recent fiscal year 2024/25, the group posted a net loss of EUR 138 million on revenue of EUR 1.58 billion. Looking ahead, however, the figures are expected to improve again. As a signal to the market, several members of the Executive Board received bonuses in the form of shares rather than cash payments in May.

E.ON: Government-Guaranteed Return on Equity Ensures Stable Grid Revenues

As one of Europe’s largest energy infrastructure operators, E.ON focuses on the regulated grid business as well as decentralized customer and decarbonization solutions. In the grid segment, the Group’s revenue model is based on government-guaranteed returns on equity and regulated grid usage fees, which are largely independent of economic fluctuations. In fiscal year 2025, the Group invested a record EUR 8.5 billion primarily in new connections and grid capacity to further expand renewable energy. The trend is already well established. Around 70% of Germany’s onshore wind power capacity and nearly 50% of its photovoltaic capacity now flows through the E.ON grid.

A.H.T. Syngas: Strategic Shift to the Contracting Model

The cleantech company A.H.T. Syngas Technology builds, plans, and manages decentralized energy plants worldwide. The technological foundation is the patented dual-combustion process, which converts biogenic waste, wood residues, or sewage sludge into high-quality, virtually tar-free synthesis gas. To mitigate the high volatility of the pure project business, the management team led by CEO Gero Bernhard Ferges is transitioning to a long-term contracting model as an independent power producer.

Going forward, the company will operate plants itself and generate recurring revenue from the sale of electricity, heat, and gas, which is expected to raise gross margins from a historical average of around 10% in plant construction to a projected 18% in contracting. In May of this year, A.H.T. strengthened its position in the Polish market with the entry of its partner INNOTEC Energy as a strategic shareholder. Together with INNOTEC, A.H.T. is working on a pipeline of 17 projects in Poland, from which management estimates a realizable total volume at the corporate level of over EUR 30 million. According to management, the Polish business alone could generate a short-term realizable order volume of at least EUR 10 million in fiscal year 2026.

Convertible Bond and Restructuring of the Japan Business

To secure liquidity for the construction of the Polish projects, the Executive Board announced in early January 2026 the full placement of a convertible bond with a total nominal value of up to EUR 2 million, excluding statutory subscription rights. This three-year convertible bond bears interest at 5% p.a. and guarantees creditors a conversion price of EUR 1.25 per share. The capital injection also helped offset operational delays in Japan.

Conclusion: Undervaluation Points to High Comeback Potential

Billion-dollar acquisitions by major corporations—such as Shell’s purchase of the Danish company Nature Energy for just under USD 2 billion or BP’s acquisition of Archaea Energy for USD 4.1 billion—demonstrate the industry’s strong willingness to make acquisitions in the biomass sector. While E.ON stands out as a defensive core investment with a stable dividend and Verbio aims to expand its margins, A.H.T. Syngas offers the most dynamic turnaround profile. Last December, the research firm GBC AG rated the stock as a clear “Buy” with a fair price target of EUR 8.50. With a share price around EUR 3 and a single-digit market capitalization, the valuation does not even begin to reflect the company’s recent operational successes. Although investors must take into account the risk of dilution in the event of a full conversion of the bond, the transition to contracting and the successes in Poland show that A.H.T. is on the right track.
