E.ON - Update 10/22/2026 - ISIN DE000ENAG999

Show notes

Many people know E.ON from their electricity bill. Behind it is the operator of Germany’s longest power and gas grids, with further grids in Sweden and in Central and South-Eastern Europe and customers in several European countries. 


Warren Wise examines the 2025 annual report using the image of a family home with solar panels and a two-way meter: the roof stands for the cash generated by the business, consumption for investment and the dividend, power bought in for new debt. Our Warren Wise report gives Score 1 of 5. 


So where does the equity story stand?

  • Score 1 is the knockout zone: currently not investable
  • A strong roof: 2025 guidance met, the grid delivers most of the earnings – for Warren Wise a genuine moat
  • The meter: what the bottom line shows over three years – and what buying in power costs in interest
  • The extension to the roof: billions for grid expansion until 2030 – and who has a say in what it will one day deliver


Questions the episode answers:

  • What stands out most when looking at E.ON's equity story?
  • Which three questions would Warren Wise put to CEO Leonhard Birnbaum?


Verdict: Score 1/5 – knockout zone, currently not investable
