Insights

Financial Analyst

TL;DR: Routine insider sale by an officer; disclosed holdings remain clearly stated and the transaction appears immaterial.

The Form 4 shows Tetlow Jacob executed a sale of 56 Pinnacle West shares on 08/11/2025 at $92.37. Following the sale the filing reports 6,496 shares held directly and 2,471 held indirectly via a 401(k). For investors, the filing transparently separates direct and indirect ownership and records the sale with code S, indicating a simple disposition rather than a derivative or complex transaction.

Corporate Governance Expert

TL;DR: Disclosure is straightforward and conforms to Form 4 structure; direct and indirect holdings are separately reported.

The filing names the reporting person and relationship (EVP, COO, APS) and reports a direct sale of common stock (transaction code S). It lists the post-transaction direct ownership as 6,496 shares and indirect ownership of 2,471 via a 401(k). The Form distinguishes the direct disposition from indirect holdings, which supports clear insider reporting and traceability of the officer's holdings.
