Consequently, actual results or outcomes may vary materially from what is contained in a forward-looking statement.

Factors which may cause actual results to be different than those expected or anticipated include, but are not limited to:

the outcome and timeliness of regulatory commissions’ actions concerning rate relief and other matters, including with respect to the 2024 CA GRC and the GRCs of our other subsidiaries;

Federal governmental and state regulatory commissions’ decisions, including decisions on proper disposition of property;
