Key Dates

Recommendation

The significant infrastructure damage and customer impact from wildfires present considerable near-term challenges and potential financial strain. While the company is actively managing the crisis and has restored some services, the extent of the damage and the prolonged restoration process for natural gas service warrant a cautious 'hold' rating until the full financial and operational impact is clearer.
