Renk with AI Potential? D-Wave Shares Rebound! Is Zefiro Methane Seriously Undervalued?

Zefiro Methane: Analysts Forecast Strong Growth

Revenue growth from USD 45.18 million to USD 66.85 million, an EBITDA increase from USD 3.73 million to USD 12.22 million, and a surge in earnings per share from USD -0.01 to USD 0.05. All of this is projected from fiscal year 2025/26 (ending June 30) through 2027/28. At the same time, the company's stock is trading at around USD 0.44. As a result, analysts at GBC Research recommend buying the shares with a price target of USD 1.50. The company in question is Zefiro Methane.

Investors who have seen the recent documentary "The Hazard Below" on YouTube.de will quickly understand why analysts are optimistic about Zefiro Methane. The company is not addressing a short-term trend, but rather an infrastructure and environmental problem that has developed over decades, with potentially millions of oil and gas wells in need of remediation in the US alone. According to estimates, the number of inactive, unplugged, and undocumented wells nationwide could be as high as 2 to 4 million.

The consequences can be significant. Orphaned wells can release methane. They are located beneath forests, agricultural land, and residential areas, and increasingly on sites earmarked for AI data centers. This invisible greenhouse gas is not only a climate concern; it can also pose risks to public safety and the surrounding environment. Particularly problematic are wells where groundwater aquifers have not been adequately protected. The documentary therefore gives a voice not only to those affected, but also to scientists and environmental experts.

At the center of the search for solutions is Zefiro Methane and its subsidiary, Plants & Goodwin. The company's roots date back to 1970, when Paul Plants and George Goodwin began maintaining old oil and gas wells. From these decades of experience, the company evolved into a specialist in the decommissioning of so-called legacy wells. Today, the company focuses on professionally plugging a wide variety of boreholes. CEO Luke Plants sees this as a specialized market in which only a few providers have the necessary expertise and technical equipment to carry out such projects as a one-stop solution. Therefore, GBC's growth forecasts appear anything but conservative.

Renk: An AI Beneficiary?

Could Renk become a beneficiary of the AI boom? The company certainly suggested as much last week. According to Renk, it is increasingly benefiting from the rapidly growing demand for electricity driven by AI applications and data centers. The group supplies gearboxes, couplings, and shift couplings for gas turbine generator sets and collaborates with Siemens Energy, among others. In the US in particular, demand for gas turbines to power large AI infrastructures is rising significantly. Over the past twelve months, Renk has received orders for more than 50 turbo gearboxes and is currently qualifying its technology for additional platforms. Additional follow-on orders are expected as early as 2026.

Renk increasingly views the power generation business as a key growth driver within the Industry Business Unit. In addition to actual power generation, Renk shift clutches can also be used in so-called synchronous condensing to utilize generators for grid stabilization and increase resilience against severe fluctuations. The segment's growing importance is also reflected in order intake.

By 2026, the business is expected to account for roughly one-third of the Industry Business Unit's order intake. Thus, its relevance to the Group remains low at this point. In the first half of 2026, Group-wide order intake stood at approximately EUR 1.20 billion. Of this, only EUR 164.4 million was attributable to the Marine & Industry division—just under 14%. The share attributable solely to the industrial segment is even lower, as the EUR 164.4 million figure also includes the marine business.

D-Wave: Stock Has Rebounded Strongly

Quantum stocks have not been among the winners this year. One of the investor favourites in the sector is D-Wave Quantum. The stock has managed to gain around 25% within four weeks. Nevertheless, its performance in 2026 stands at -25%. Most recently, the quarterly results were well received. That said, given the company's market capitalization of around USD 7.88 billion, the figures naturally remain quite modest. In the second quarter of 2026, D-Wave generated USD 3.1 million in revenue, roughly the same as in the same period last year. The share of Forbes Global 2000 customers rose from 20.4% to 47.7%. Bookings also picked up. At USD 2.1 million, they were 59% higher than in the same quarter last year. For the first half of the year as a whole, bookings rose by 1,120% to USD 35.5 million.

The aggressive expansion of technology and sales activities continues to weigh on earnings. The GAAP gross margin fell from 63.8% to 55.4%. Operating expenses nearly doubled to USD 55.0 million. This is primarily due to higher personnel costs and additional investments in product development and go-to-market activities. The adjusted EBITDA loss widened accordingly from USD 20.0 million to USD 37.1 million. The net loss, however, decreased significantly from USD 167.3 million to USD 48.0 million. However, this sharp decline is primarily attributable to the elimination of high non-cash charges resulting from the revaluation of warrants.

Nevertheless, the company's strategic expansion as a provider of two quantum platforms appears to be instilling confidence in investors. For the Advantage3 annealing system, the company plans to reach 20,000 qubits by 2029 and, in the long term, 100,000 qubits by 2031. At the same time, a new roadmap for fault-tolerant gate-model systems was presented. It is expected to lead to a system with 100 logical qubits and more than one million operations by 2032. Additional momentum is coming from a research breakthrough in dual-rail architecture published in Nature, new customer projects with companies such as AT&T, Nasdaq Verafin, and Shionogi, and funding from US government programs. D-Wave is thus clearly focused on increasingly translating technological advances into larger commercial applications and recurring revenue.

Qubits are the basic building blocks of a quantum computer, comparable to bits in classical computers. This enables quantum computers to solve certain problems much more efficiently. However, it is not only the number of qubits that matters, but also their quality, interconnectivity, and error rate. In D-Wave's annealing systems, adding more qubits is primarily intended to enable direct computation of larger, more complex optimization problems on the quantum computer itself. The goal of reaching 20,000 qubits by 2029 is therefore primarily a scaling step toward significantly more powerful commercial systems.

Zefiro's stock appears simply far too cheap. The problem of orphaned oil and gas wells is enormous, and Zefiro's market position is strong. D-Wave, by contrast, is anything but cheaply valued. However, this is offset by the potential of quantum technology. Renk's AI potential should not be overstated.
