Siemens Energy AG

The order backlog of €138B at FY2025-end (approximately 3.5x annual revenue of €39.1B) provides multi-year revenue visibility well above industrial norms. Gas Services added 194 new turbines in FY2025 and Grid Technologies held orders above €21B, both contributing to a backlog that has grown for nine consecutive quarters.

Siemens Energy operates four segments, but all are tied to power generation, grid infrastructure, or energy transition — correlated end markets that tend to soften together in a policy reversal or capital cycle downturn. Gas Services is the single largest revenue contributor and likely exceeds 30% of group revenue, limiting segment-level diversification.

Revenue is drawn from operations in more than 90 countries, with FY2025 growth led by Americas and Europe/C.I.S./Africa/Middle East regions, partially offset by weakness in China. No single country is likely to exceed 40% of group revenue, though the exact regional split is not granularly disclosed.

Grid Technologies achieved a 15.8% profit margin before special items in FY2025, demonstrating some operating leverage in that segment. The broader group model remains project-engineering-intensive with significant manufacturing and labor content, limiting structural operating leverage relative to software or asset-light models.

Gas Services generates a meaningful portion of revenue from long-term service and maintenance contracts on the globally installed turbine base, a structurally sticky revenue stream. The remainder of group revenue is project and equipment sales, which are mission-critical for customers but transactional in nature.
