Broker Non-Votes financial

"For | Against | Abstain | Broker Non-Vote 795,227 | 113,598 | 5,993 | 1,361,297"

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.

evergreen percentage financial

"to increase annual evergreen percentage increase to the number of shares available"

say-on-pay financial

"Approval, on an advisory basis, of the compensation of the Company’s named executive officers"

A say-on-pay is a shareholder vote that gives investors a chance to approve or disapprove a company’s executive compensation packages, typically held at annual meetings. It matters because the vote signals investor satisfaction with how leaders are paid—like customers rating how well managers are rewarded—and can push boards to change pay plans, reducing governance risk and affecting investor confidence and stock value even though the vote is usually advisory rather than legally binding.

independent registered public accounting firm financial

"as the Company’s independent registered public accounting firm for the 2026 fiscal year"

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

"Approval, on an advisory basis, of the frequency of future advisory votes"
