Board Changes

HeiQ (LSE:HEIQ), a leading company in materials innovation and hygiene technologies, is pleased to announce the appointment of Robert Van de Kerkhof as Chairman of the Company, with effect from 1 April 2024.

Robert was appointed Non-Executive Director of HeiQ in January 2024 and subsequently, Chair of HeiQ AeoniQ. He brings a wealth of invaluable experience, having spent over 30 years in general management and sustainability leadership positions across the textiles industry.

The HeiQ Board would like to express its appreciation and gratitude to Esther Dale Kolb, current Chair, who is stepping down to pursue other interests. Esther joined HeiQ in July 2020 and retires after working more than 30 years in leadership and management positions in both the chemicals and textiles industries. Esther will remain with the business to ensure an orderly handover of duties to Robert.

Esther Dale-Kolb, Non-Executive Director and retiring Chair of HeiQ plc, commented: "I have taken the difficult decision to retire as Chairwoman of HeiQ plc to pursue other interests, With HeiQ moving to its next phase and scaling up of HeiQ AeoniQ, I feel that now is the right time to hand over the Chair's position to Robert, given his wealth of expertise in sustainable textiles as well as senior leadership experience.

I would like to thank my co-directors on the Board of HeiQ plc and our shareholders for their support since our IPO in December 2020. I am pleased to have played a part in recruiting Robert and welcome him as the new Chair. His extensive experience and proven leadership in sustainability and textiles will be invaluable as HeiQ continues its mission of innovating and disrupting the industry. As I retire from my role, I am confident that Robert will lead the company to new heights, and I look forward to seeing HeiQ's future successes."

Robert van de Kerkhof, HeiQ plc Non-Executive Director, commented: "I am honoured to accept the role of Chairman at HeiQ. I look forward to collaborating with the talented team to drive forward our strategic objectives, fostering sustainable practices, and delivering value for our shareholders."
