Filing Released Lang Actions
FORM 8-K
Share Issue/Capital Change Classification · 98% confidence The document is a U.S. SEC Form 8-K current report (Section 13/15(d)) describing the First Amendment to the Equity Distribution Agreement, which governs at-the-market offerings of common stock (share issuance facility). This constitutes an announcement of a share issuance arrangement (capital change), fitting the Share Issue/Capital Change category rather than a pure report publication or unrelated item.

FORM 8-K
Capital/Financing Update Classification · 78% confidence The document is a U.S. SEC Form 8-K “Current Report” filed by Pinnacle West Capital Corporation, dated June 1, 2026.
