Siemens Energy: Oman's 2.6GW Order and an S&P Upgrade Set the Stage for an August Verdict

Siemens Energy secures major Oman power plant contract, ramps up gas turbine output, and gets S&P upgrade. Shares rally 8.8% weekly as RBC lifts target to €210.

Siemens Energy has emerged from the first half of 2026 with the strongest tailwind it has seen in years. A major contract to build two power plants in Oman, together pumping out nearly 2.6 gigawatts, will boost the sultanate's energy production by roughly a fifth. The Munich-based group is simultaneously ramping up annual production capacity for medium-sized gas turbines from 50 to 80 units in the second half of this year, a direct response to insatiable global demand for flexible power generation.

The operational momentum was underpinned on 3 July by a credit rating upgrade from S&P Global Ratings, which pushed the long-term issuer rating from BBB to BBB+ with a stable outlook. The agency cited an expected improvement in profitability and cash flow, driven in large part by the turnaround at Siemens Gamesa. The wind power subsidiary is on track to break even in 2026 and deliver positive EBITDA margins the following year.

For the wider group, S&P sees adjusted EBITDA margins of 13.5% to 14.0% in fiscal 2026, rising to 15.5% to 16.0% in fiscal 2027. Management has committed to defending the investment-grade rating and achieving a stable net cash position by 2028. A €6 billion share buyback programme, to be completed by the end of that year, is already underway.

The market has taken note. Siemens Energy shares closed on Friday at €167.88, gaining 2.05% on the day and 8.82% over the week. The stock has added 36.71% since the start of the year and a stunning 81.49% over the past twelve months. Yet it still sits 14.15% below the 52-week high of €195.54 reached in April. Technically, the share price hovers just above its 50-day moving average of €167.67 and well above the 200-day line at €141.47. A volatility reading of nearly 60% tells investors that calm is rarely the order of the day.

RBC Capital Markets lifted its price target from €200 to €210 on Friday, maintaining an "Outperform" rating. The bull case rests on the core segments Gas Services and Grid Technologies, which are riding the twin waves of grid modernisation and surging electricity demand from artificial intelligence data centres. The group recently set up a new AI-driven development platform with an IT partner to keep pace with that demand. However, the valuation remains a point of debate: the stock trades at a price-to-earnings ratio of roughly 67, a level that leaves little room for error.

Since 1 July, Siemens Energy has been in a quiet period ahead of its quarterly results on 5 August. The next few weeks will determine how many of the non-binding capacity reservations in the pipeline convert into firm orders, how margins in the crucial grid unit are holding up, and whether the much-touted AI boom is leaving tangible marks on the books. The S&P upgrade and the bulging order book provide a solid frame of reference, but the August report will deliver the first real proof point in a story that has so far been driven more by narrative than by hard numbers.
