Annual General Meeting of Shareholders regulatory

"announced today that has convened its Annual General Meeting of Shareholders to be held on May 12, 2026"

Extraordinary General Meeting of Shareholders regulatory

"and an Extraordinary General Meeting of Shareholders to be held immediately after the adjournment"

A meeting called by a company outside its regular annual meeting to address urgent or special matters that cannot wait until the next scheduled meeting. Investors attend or vote to decide on actions such as major deals, leadership changes, capital-raising, or rule changes; think of it as an emergency board meeting where shareholders have a direct say and the outcomes can quickly change a company’s strategy, ownership stakes, or financial prospects.

Shareholder Meeting Brochure and Proxy Statement regulatory

"the Shareholder Meeting Brochure and Proxy Statement (which contains the procedure for attending and/or voting"

Compensation Report financial

"the 2025 Compensation Report;"

articles of association regulatory

"the proposed amendments to the articles of association;"

A company's articles of association are its written rulebook that sets how the business is run, how decisions are made, and what rights owners and directors have—covering voting, meetings, appointment and removal of directors, share classes and dividend policies. For investors, these rules matter because they determine how easily control can change, what protections minority owners have, and how corporate actions (like issuing new shares or changing leadership) are approved, much like a home’s bylaws shaping what residents can and cannot do.
