Director Declaration

In accordance with UK Listing Rule 6.4.6 the Company announces that Neil Johnson has assumed the role of executive chair of the Company with immediate effect. There will be no change in Neil's responsibilities resulting from this role change.

The change in role from non-executive chair to executive chair results from his participation in the Company's value creation plan, as approved by shareholders at the Company's 2024 AGM, and is in accordance with the rationale set out on page 6 of the notice of the Company's 2024 annual general meeting (which can be accessed at www.dialight.com/ir/shareholder-information/general-meetings/) and on pages 59, 63 and 66 of the Company's 2024 annual report (which can be accessed at www.dialight.com/ir/reports-news/).

The salary payable to Neil in respect of his executive chair role is the same as the fee level he was entitled to as the non-executive chair. He will not be entitled to any other benefits, pension contributions, nor participation in the Company's Restricted Share Plan or Annual Performance Bonus Scheme.
