Lead Independent Director regulatory

"ratified the nomination of the Director Wilfred Theodoor Bruijn as Lead Independent Director"

A lead independent director is a board member who is not part of company management and is chosen to coordinate and represent the other independent directors, often running sessions without the CEO, helping set meeting agendas, and serving as a liaison between shareholders and the board. For investors, this role signals stronger, more balanced oversight—like a neutral referee who helps ensure decisions are fair, transparent and focused on protecting shareholder interests.

Nomination and Governance Committee regulatory

"with the favorable opinion of the Nomination and Governance Committee ("CIG")"

Internal Regulations regulatory

"the amendment of item 2.1.(ii) of the Internal Regulations of the CIG"

Bylaws regulatory

"pursuant to article 11, paragraph 8 of the Company's Bylaws"

Corporate bylaws are a company's internal rulebook that explains how the business is run day to day — who makes decisions, how directors and officers are chosen, how shareholder meetings are conducted, and procedures for changes or conflicts. For investors, bylaws matter because they shape governance and control, influence how quickly and easily leadership or strategy can change, and can protect or limit shareholder rights much like house rules affect how a household operates.
