2G Energy: Data Centre Windfall Powers Rally, but ERP Glitch Delays the Verdict

2G Energy stock soared 85% YTD on a record data center contract, but an ERP migration delays 2025 earnings to June, while INNIO's IPO offers a new sector valuation benchmark.

The share price of 2G Energy has more than doubled over the past twelve months, yet investors are still waiting for the hard numbers that would justify the move. An enterprise resource planning (ERP) migration at the newly established production subsidiary has pushed the entire reporting schedule deeper into the year, leaving the market to trade on momentum and order flow alone.

Record Contract Reshapes the Outlook

The recent surge — roughly 85% year-to-date, with shares changing hands at €67.75 on Friday — is anchored to a single landmark contract. 2G will supply containerised power plants with a combined capacity in the low triple-digit megawatt range to a data centre client, with deliveries commencing in the second half of 2026. For 2027 the management is targeting revenue between €570 million and €620 million, alongside an EBIT margin north of 11%.

The order has already prompted a flurry of analyst adjustments. First Berlin Equity Research lifted its price target to €73 but downgraded the stock from “Buy” to “Add”, noting the implied upside had shrunk to only 8% at current levels. Guido Hoymann at Bankhaus Metzler set a €74 target, while Malte Schaumann at Warburg Research went further to €80, arguing the breakthrough into the data centre segment cements the growth narrative.

INNIO’s Debut Sets a New Benchmark

A fresh valuation yardstick is now coming from across the Atlantic. US rival INNIO launched its Nasdaq roadshow on Tuesday, targeting a valuation of up to $20.25 billion. By comparison, 2G Energy’s market capitalisation stands at roughly €1.5 billion. The IPO creates a clearer comparable for the decentralised energy infrastructure space, but it also introduces risk: should INNIO’s eventual valuation disappoint, the entire sector could feel the spillover effect.

Margin Pressure Clouds the Near Term

Despite the revenue visibility, profitability remains a sticking point. For 2025, the company has guided towards the lower end of its 6.5% to 8.0% EBIT margin range, citing costs related to the data centre ramp-up and the ERP transition, which is particularly weighing on the German service business. Moreover, the new-build unit saw sales grow to around €230 million last year — an 11% increase year-on-year — but that performance predates the windfall contract.

Technical indicators also flash a note of caution. With a relative strength index of 38.0, the stock’s recent sprint may have left it overextended, raising the odds of a pullback or at least a period of consolidation.

Delayed Earnings Put the Rally to the Test

The real test of the current valuation is still weeks away. Preliminary 2025 results are now scheduled for mid-June, followed by the full annual report in the same month. First-quarter 2026 figures are expected in June or July, though management has not ruled out further slippage due to the ongoing software integration. Crucially, the delay stems from an IT implementation challenge, not from any operational deterioration.

What Investors Will Watch

When the numbers finally land, all eyes will be on the EBIT margin actually achieved in 2025. That metric will determine whether the 117% share-price surge over the past twelve months is built on solid foundation or merely reflects hopes that have run ahead of reality. In the meantime, 2G is in negotiations with additional data centre operators for further orders in the low triple-digit megawatt range — deals that could provide the next catalyst, but only if the margin story holds up.
