8-K
Earnings Release Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated August 6, 2025, reporting the earnings results for the fiscal quarter ended June 30, 2025. It includes a press release (Exhibit 99.1) and a slide presentation (Exhibit 99.2) related to the quarterly earnings conference call. The document explicitly states it is furnishing results of operations and financial condition pursuant to Item 2.02, which corresponds to earnings releases and related disclosures. The presence of a press release and slide presentation for the quarter's financial results aligns with the definition of an Earnings Release (ER). The document is not the full quarterly report (which would be an Interim/Quarterly Report IR), but rather the initial announcement of quarterly financial results and highlights. Therefore, the correct classification is Earnings Release (ER).

8-K
Investor Presentation Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The text mentions "Item 7.01 Regulation FD Disclosure" and that Pinnacle West will be using handouts at meetings with analysts and investors, with the handouts attached as Exhibit 99.1. This indicates the document is primarily an announcement of investor presentation materials rather than the presentation itself. The document length is 4181 characters, which is relatively short and consistent with an announcement rather than a full report. There is no detailed financial data or comprehensive report content present. Therefore, this filing is best classified as an Investor Presentation announcement within a Form 8-K, which aligns with the category Investor Presentation (IP).

8-K/A
Regulatory Filings Classification · 95% confidence The document is a Form 8-K/A (Amendment No. 1) filed with the SEC, which is a Current Report under the Securities Exchange Act of 1934. It amends a previously filed Form 8-K to correct a specific financial figure related to a rate case. The content focuses on regulatory and financial updates regarding a rate increase application and related proposals, but it does not contain comprehensive financial statements or detailed financial performance data typical of an Annual Report or Interim Report. The document is a regulatory filing providing an update and correction to a previously filed report, consistent with the nature of SEC Form 8-K amendments. Therefore, it fits best under Regulatory Filings (RNS) as it is a regulatory announcement and amendment rather than a full financial report or other specific filing type.

8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The content focuses on the filing of a rate case application with the Arizona Corporation Commission, including detailed proposals for rate increases and capital structure. It includes a press release as an exhibit and forward-looking statements. There are no comprehensive financial statements or detailed financial analysis typical of an Annual Report (10-K) or Interim Report (IR). The document is not a transcript, proxy, or governance report. It is a regulatory filing announcing a significant event (rate case filing) and related disclosures. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous SEC filings like Form 8-K that do not fit other specific categories.
2025-06-13 English
11-K
Annual Report Classification · 100% confidence The document is a Form 11-K filed with the SEC, which is an annual report for employee stock purchase, savings, and similar plans pursuant to Section 15(d) of the Securities Exchange Act of 1934. It includes audited financial statements, notes, and a report of the independent registered public accounting firm. The document covers the fiscal year ended December 31, 2024, and contains detailed financial data and disclosures about the Pinnacle West Capital Corporation Savings Plan. Given the nature of Form 11-K as an annual report for employee benefit plans, this filing is best classified under the Annual Report category (10-K) as it is a comprehensive yearly report with full financial performance details, even though it is a specialized form for employee benefit plans rather than a corporate 10-K. The document length and content confirm it is the report itself, not just an announcement or certification.
