Annual Meeting of Stockholders regulatory

"held its 2026 Annual Meeting of Stockholders"

Broker Non-Votes regulatory

"For | Withheld | Broker Non-Votes"

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.

independent public accountants regulatory

"APPROVAL OF THE APPOINTMENT OF THE CORPORATION’S INDEPENDENT PUBLIC ACCOUNTANTS"

non-binding vote regulatory

"APPROVAL, BY NON-BINDING VOTE, OF SCC’s EXECUTIVE COMPENSATION"

A non-binding vote is an advisory vote where shareholders or stakeholders express their opinion on a proposal without creating a legal obligation for the board or management to follow the result. It matters to investors because the outcome acts like a public opinion poll—informing market participants about shareholder sentiment and often influencing future corporate decisions, governance changes, or investor confidence even though it does not force action.
