Summary

Our base-case estimate uses a valuation based on adjusted earnings per share and a normalized price-to-earnings multiple. We then blend that result with the average analyst price target of $219.72 from 48 analysts, using a 30% weight on analyst consensus. That produces an estimated intrinsic value of $208.67 per share.

Warnings

The company's reported profits differ from official accounting profits by 65%. Check what costs are being left out of the adjusted number.

Key Risks

  • Growth DCF inappropriate — terminal value assumptions dominate
  • EV/EBITDA misleading for regulated businesses where capex is mandated
  • Regulatory risk is a fat tail not visible in normal multiples
