Siemens Energy Q2 Results Beat Expectations; FCF Guidance Doubled to €8 Billion

Overview

This report is part of the Goldman Sachs Utilities Daily series, focusing primarily on Siemens Energy's fiscal year 2026 second-quarter earnings review. The report notes that Siemens Energy's officially released Q2 results are consistent with and stronger than prior pre-disclosures. The company significantly upgraded its full-year free cash flow, margin, and revenue growth guidance, and announced an acceleration of share buybacks. Goldman Sachs maintains a 'Buy' rating, arguing this confirms favorable fundamentals such as grid capex and energy security demand, and that strong execution is likely to help narrow the valuation gap with competitor GE Vernova. Additionally, the report explores the upside potential of renewable energy developer EDPR and covers the latest developments regarding E.ON's acquisition of UK-based OVO Energy.

Core views

Siemens Energy Q2 performance drives a significant upward revision of full-year guidance. The company expects pre-tax free cash flow for FY26 to be approximately €8 billion, a substantial increase from the previous guidance range of €4-5 billion; adjusted margin guidance was raised from 9-11% to 10-12%; comparable revenue growth guidance was raised from 11-13% to 14-16%. Notably, the new margin guidance for the Grid Technologies segment implies that the sector's original 2028 fiscal year target has been achieved two years ahead of schedule. Goldman Sachs views this as validation of market expectations for gas turbine improvements and highlights the company's superior delivery capabilities in the grid business. Enhanced shareholder returns strengthen valuation recovery logic. Building on positive performance, Siemens Energy is accelerating the FY26 share buyback volume by up to €1 billion, and the initial €2 billion buyback tranche is nearing completion. Goldman Sachs indicates that investor focus should now shift to assessing the magnitude of profit upgrades for the 2028 fiscal year commercial plan discussed during the conference call. This strong delivery serves as further evidence that the company's execution is improving, helping to narrow the valuation discount relative to GE Vernova, which exceeds 50% in terms of the 2028 expected EV/EBITDA multiple. EDPR Upside Case: Financing Bottleneck Removal Unlocks High Growth. Despite net investments of approximately €8 billion since 2020 and a 65% increase in installed capacity, EDPR's base profitability remains at pandemic-era levels, with an average ROE of only 2% from 2020-2026. Leverage limits its ability to accelerate growth. Goldman Sachs calculates that if incremental external financing of approx. €1.5 billion were obtained, EDPR's annual new installations could gradually rise to 2GW by 2030 (three times current levels). In this scenario, 2028 EPS would be 15% above baseline forecasts, 2031 EPS would lead market consensus by 25%, and the 2026-2031 EPS CAGR could reach 20%. Coupled with upside revisions in earnings targets, this could become a key catalyst for stock re-rating. Industry M&A and Transformation Dynamics. E.ON has signed an agreement to acquire UK energy supplier OVO, with the transaction expected to complete in the second half of 2026. This will bring approx. 4 million new customers to E.ON in the UK (existing base of 5.6 million), though no specific acquisition price was disclosed. Furthermore, the penetration rate for heat pumps in Germany surged to 48% in 2025 (up from 27% the previous year), with sales volume approx. 300,000 units, while the market share for gas boilers fell approx. 45%, indicating an acceleration in end-use electrification trends.

Analysis framework

This report employs an 'Event-Driven + Peer Benchmarking' framework to interpret Siemens Energy's earnings. First, it verifies earnings quality by comparing pre-disclosure data with official financial statements. It then focuses on dissecting changes in forward-looking guidance for Free Cash Flow (FCF) and margins, using these as indicators of a corporate inflection point rather than solely historical performance. On the valuation front, analysts do not view Siemens Energy in isolation; instead, they introduce peer benchmark GE Vernova for horizontal comparison. By calculating the relative discount in their 2028E EV/EBITDA multiples, 'earnings beating expectations' is translated into concrete 'valuation recovery space,' thereby justifying the Buy rating. For the analysis of EDPR, a 'Constraint Release' scenario analysis approach is adopted: identifying the single critical variable limiting growth (leverage/capital), and quantifying the elasticity impact of this variable's improvement on EPS to uncover upside option value overlooked by the market.

Methodology notes

• Event Gaming and Behavioral FinanceExpectation Gap / Expectation Management

  Verification Mechanism Between Pre-disclosure and Official Financial Reports

  The report confirms earnings certainty by comparing the consistency of data between 'pre-release' and 'official release', and creates a positive expectation gap through significant guidance upgrades (e.g., FCF jumping from €4-5bn to €8bn). This is the core signal for institutions to capture opportunities for stock re-rating.

• Valuation methodsEV/EBITDA valuation

  Peer Relative Valuation and Discount Convergence Logic

  The report uses 2028 expected EV/EBITDA multiples as an anchor. By comparing valuation differences between Siemens Energy and GE Vernova (>50% discount), it directly maps improved operational execution to potential valuation recovery gains, rather than relying solely on absolute PE ratios.

• Corporate Fundamentals and Financial FrameworkROIC–WACC spread

  Divergence Analysis of ROE and Capital Investment Efficiency

  In analyzing EDPR, the report points out that despite massive capital investment (+65% capacity), the average ROE was only 2%, implying return on investment is below the cost of capital. This diagnosis of 'revenue growth without profit growth' is a prerequisite for determining whether the company needs to alter its financing strategy or asset structure.

Impact & implications

For Siemens Energy, the significant upgrade in FCF guidance not only improves the numerator in the current valuation model but, more importantly, signals a structural improvement in grid business profitability. This provides fundamental support for the company to consistently outperform peers before 2028. For EDPR, the upside case proposed in the report essentially calls on management to adopt a more aggressive capital operation strategy. Should actions such as rights issues or introducing strategic investors occur in the future, they will be viewed as clear buy signals. For the industry, E.ON's acquisition and the surge in German heat pump data further confirm that European utilities are in a super-cycle driven by electrification and AI computing power demands. Vertically integrated operators capable of organic growth may face a re-evaluation of value.

Risks

• Siemens Energy's 2028 fiscal year commercial plan profit upgrade may fall short of market expectations
• EDPR faces credit tightening risk, potentially leading to failed incremental financing or increased costs
• EDPR's asset rotation strategy may exacerbate earnings volatility in adverse scenarios
• E.ON's acquisition of OVO does not conclude as scheduled in H2 2026

What to watch

• Specific guidance on the magnitude of 2028 fiscal year profit upgrades during Siemens Energy's Q2 earnings conference call
