Investor Verification Checklist
- Verify the final CPUC decision on the revenue adjustment, which could range from a $15 million decrease to an $86 million increase.
- Monitor the settlement deadline of July 8, 2026, for potential negotiated outcomes between PSCo and regulators.
- Assess the impact of the proposed lower ROE (8.50% - 9.20%) versus the requested 10.75% on future earnings.
- Review the treatment of the $100 million depreciation expense adjustment, which is noted as largely earnings neutral but affects cash flow and rate base.
- Confirm the effective date of any new rates, currently anticipated for Q4 2026.
