Investor Verification Checklist
- Verify the final NMPRC decision on the revenue increase, which is expected in Q4 2026, against the current $168 million request.
- Monitor the approved Return on Equity (ROE) and equity ratio, as intervenors recommend significantly lower figures (8.10% to 9.75%) than SPS's 10.5% request.
- Assess the impact of the rate suspension ending November 30, 2026, on cash flow if the final decision is delayed.
- Review the specific adjustments to purchased power capacity costs and depreciation expense, which were major points of contention among intervenors.
- Check for any updates on wildfire liability insurance coverage and potential regulatory penalties mentioned in the risk factors.
