annual general meeting of shareholders financial
"On May 14, 2026, Prothena Corporation plc held its annual general meeting of shareholders"
independent registered public accounting firm financial
"the appointment of KPMG LLP as the Company’s independent registered public accounting firm"
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.
non-binding advisory vote financial
"The shareholders approved, in a non-binding advisory vote, the compensation of the Company’s executive officers"
A non-binding advisory vote is a shareholder vote that expresses investors’ opinion on a proposal (such as executive pay, corporate policy, or governance practices) but does not legally force the company to act. Think of it like a customer survey: it signals whether owners approve or disapprove and can pressure boards and managers to change course, so investors watch the result as an indicator of governance risk and potential future shifts in company strategy or leadership.
broker non-votes financial
"Broker Non-Votes 7,374,142"
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.
Audit Committee financial
"the Company’s Board of Directors, acting through its Audit Committee, to approve the remuneration"
A company's audit committee is a small group of board members who act like independent inspectors for the firm's finances, overseeing how financial reports are prepared, monitoring internal controls, and managing the relationship with external auditors. Investors care because a strong audit committee reduces the risk of accounting errors, fraud, or misleading statements, making financial statements more trustworthy and helping protect shareholder value.
