Siemens Energy vs Sungrow Power Supply: why the prices moved differently

• ▲

  AI data centers drive gas turbine demand and pricing AI data centers are straining power supplies, and gas turbines are the bottleneck. Siemens Energy's gas turbine backlog hit 69 GW, with 15 GW of new orders and 18.5% revenue growth. Turbine prices could nearly triple by end-2027, boosting future profits.

  This is the core force behind the stock: surging AI power demand lifts orders, backlog and pricing for Siemens Energy's gas turbines.

  Concrete nuclear and grid orders add to backlog Siemens Energy won a C$1.3bn contract to replace turbine generators at Ontario's Pickering nuclear plant, and its grid-stabilizing technology will be used in a $50M DOE-funded Texas project. These are firm orders that support future revenue.

  New contract wins show Siemens Energy converting demand into signed orders beyond gas turbines, supporting the growth story.

• ▲

  Steam turbine unit sale moves closer with €7bn debt package Bankers are arranging up to €7bn in debt to finance a majority stake sale of Siemens Energy's steam turbines unit, potentially valuing it above €10bn. This would let Siemens Energy focus on its core power generation and grid business.

  The sale is a major capital move that could sharpen the company's focus and unlock value, directly affecting the investment case.
