Annual Meeting of Shareholders financial

"On May 14, 2026, at the Annual Meeting of Shareholders (the “Annual Meeting”) of Pinnacle West Capital Corporation"

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.

broker non-vote financial

"FOR | WITHHELD | BROKER NON-VOTE Glynis A. Bryan | 95,980,735 | 5,797,567 | 8,715,982"

A broker non-vote happens when a brokerage firm holds shares in street name for a client but does not cast a ballot on a particular shareholder item because the broker lacks discretionary authority to vote that matter. Think of it like a person who owns a ticket but the ticket-holder refuses to vote on some issues; the share counts for ownership but not for that vote, which can affect whether proposals reach the required number of votes or a quorum.

advisory vote on executive compensation financial

"Proposal 2. The shareholders approved an advisory vote on executive compensation."

A non-binding shareholder vote allowing investors to approve or reject the pay packages and compensation policies for a company’s top executives. It matters because the outcome tells the board whether owners are satisfied with executive pay and can prompt changes in policy or leadership much like a customer survey prompts a company to adjust its product — signaled approval can support management credibility, while rejection may increase scrutiny and affect investor confidence.

independent accountant financial

"Proposal 3. The shareholders ratified the appointment of Deloitte & Touche LLP as the Company’s independent accountant"
