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.

Regulation FD Disclosure regulatory

"Item 7.01 Regulation FD Disclosure. On May 4, 2026, the Company issued a press release..."

Regulation FD disclosure requires public companies to share important, market-moving information with everyone at the same time instead of tipping off analysts or large investors first. Think of it as making sure all players on a field hear the same announcement simultaneously; that fairness helps investors trust that stock prices reflect the same information and reduces the risk of sudden, unfair trading advantages or regulatory penalties for selective leaks.
