broker non-votes financial

"There were 25,018,609 broker non-votes as to Proposal 2."

Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.

Named Executive Officer Compensation financial

"Proposal 2: Approval of Named Executive Officer Compensation on an Advisory Basis."

Pay and benefits disclosed for a company’s top executives identified in regulatory filings, including salary, bonuses, stock awards, option grants, pension contributions and other perks. Think of it as a public paycheck summary for senior managers that shows how they are rewarded and motivated. Investors use it to judge whether executive incentives align with shareholder interests, to assess potential costs and risks, and to evaluate corporate governance.

independent registered public accounting firm financial

"Ratification of the Appointment of Deloitte & Touche LLP as the Company’s Independent Registered Public Accounting Firm for 2026."

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.

advisory basis financial
