- Test Year: Based on the twelve months ended June 30, 2022, with adjustments for twelve months of post-Test Year plant.
Outlook, Risks, and Management Commentary
APS has requested that the rate increase become effective on December 1, 2023. Management explicitly states that the outcome of the request cannot be predicted. The filing includes standard forward-looking statement disclaimers, noting that actual results may differ materially from expectations due to various risks detailed in the company's Form 10-K and Form 10-Q filings. The filing does not provide updated revenue, profit, or cash flow figures for the company's operations.
Investor Verification Checklist
- Verify the status of the ACC docket E-01345A-22-0144 to track the regulatory approval process.
- Confirm the final approved rate increase amount and effective date, as the requested 13.6% increase is not guaranteed.
- Review the company's most recent Form 10-Q or 10-K for actual historical financial performance, as this 8-K contains only proposed rate figures.
- Assess the impact of the proposed capital structure (48.07% debt) on the company's future leverage and interest expense.
