 written confirmation of independence of each independent director. The Board of Directors believes that with their diverse business and professional backgrounds, each nominee will continue to bring to the Board of Directors valuable perspectives, skills, and experience that will complement the Board’s diversity and optimal composition. Among the returning Directors, Nisa Bernice Wing-Yu Leung was appointed as a director of the Company in August 2014 and an independent director of the Company since July 2020, so she has served on the Board for more than nine years. The Board of Directors is of the view that Ms. Leung is still independent.

If elected at the Annual Meeting, each of these nominees would serve until the 2026 annual general meeting and until his or her successor has been duly elected and qualified or, if sooner, until the director’s death, resignation, or removal.
