2G Energy's 400-Million-Euro Quarter: A Stock That Jumped 7.9% While the Street Argues Over the Fine Print

2G Energy raised 2027 revenue guidance to EUR 600-650 million after Q3 order intake topped EUR 400 million, but analysts remain split.

Shares of 2G Energy climbed 7.9% on Tuesday, closing at EUR 61.00, after the combined heat and power specialist disclosed an order intake north of EUR 400 million for the third quarter of 2026. The company paired that headline figure with upgraded revenue guidance, and investors responded with the kind of enthusiasm that had been conspicuously absent in recent weeks.

Guidance Raised Across the Board

Management now expects revenues of EUR 600 million to EUR 650 million in 2027, up from a previous target of EUR 570 million to EUR 620 million. For the first time, the board also offered a glimpse into 2028, projecting sales of between EUR 750 million and EUR 850 million. The market's reaction underscored how starved investors had been for concrete evidence of growth.

The Energy Vault Order at the Center of It All

The foundation for the renewed optimism was laid roughly a week earlier, when Energy Vault Holding Inc. placed an order for containerized power generation systems totaling 275 MW, destined for AI data centers in the United States. Deliveries are scheduled to begin in the fourth quarter of 2027 and run through the third quarter of 2028, with long-term servicing included in the agreement.

Between the Energy Vault announcement and Tuesday's quarterly update, the stock had slipped 6.9% as market participants cautiously weighed the deal's actual impact on medium-term earnings. The interim report on order intake appears to have erased those doubts about execution speed. Demand from the energy-hungry technology sector is now a tangible growth driver, and 2G Energy's ability to book such volumes speaks to a strong position in the market for decentralized energy solutions.

Beyond the data-center contract, the company also flagged an additional large order in the pipeline from the mining sector. Preliminary figures for the first half of 2026 were released as well, though without detailed metrics attached.

Two Analysts, Two Very Different Conclusions

Despite the momentum, opinion on the stock remains strikingly divided. First Berlin Equity Research confirmed its buy rating on Friday and lifted its price target from EUR 76.00 to EUR 83.00, crediting the potential of the recent large-scale contracts. Parmantier & Cie. GmbH took the opposite stance the following day, reiterating a sell recommendation with a target of just EUR 39.00.

The bear case rests largely on operating history. Total output in the first six months of fiscal 2026 came in at EUR 184.0 million, down from EUR 193.0 million in the same period a year earlier. The EBIT margin was a thin 0.6%, compared with 3.3% in the prior-year period.

Parmantier's analysts also pointed directly at the Energy Vault contract, noting that key terms remain undisclosed. The company has yet to publish details on payment conditions, advance payments, or penalties in the event of cancellation. Their broader argument is that a well-stocked order book alone does not guarantee adequate returns — management still has to prove that working through these new projects won't come at the expense of profitability.

A Strong Year, With Caveats

Even with those reservations about contractual safeguards, shareholders have had a rewarding run. The stock is up 74% since the start of the year. At a current market capitalization of EUR 1.05 billion, the market is already pricing in part of the anticipated expansion.

Whether the recent surge continues will depend heavily on how transparently management handles the remaining terms of these major projects — and on how the order backlog actually translates into revenue once deliveries begin in late 2027. If 2G Energy hits its 2028 revenue corridor and operating margins recover, there may be room for further upside. For now, the direction is clear, even if the details are not.
