Where a Member (whether individual or corporate) who is not a Relevant Intermediary (as defined below) is entitled to appoint not more than two (2) proxies, the appointments shall be invalid unless such Member specifies the number of Shares to be represented by each proxy. Please note that proxy will be given the same rights as Member. A Member, who is a Relevant Intermediary, is entitled to appoint more than two (2) proxies to attend, speak and vote at the EGM, but each proxy must be appointed to exercise the rights attached to a different Share or Shares held by such Member. Where such Member’s instrument appointing a proxy(ies) appoints more than two (2) proxies, the number and class of Shares is held in relation to which each proxy has been appointed must be specified in the instrument appointing a proxy(ies). “ Relevant Intermediary ” means:

• (a) a banking corporation licensed under the Banking Act 1970 of Singapore or a wholly-owned subsidiary of such a banking corporation, whose business includes the provision of nominee services and who holds shares in that capacity;

• (b) a person holding a capital markets services license to provide custodial services for securities under the Securities and Futures Act 2001 of Singapore and who holds shares in that capacity; or

• A proxy need not be a member of the Company.

• Investors holding shares under the Central Provident Fund Investment Schemes members (“ CPF Investors ”) and/or Supplementary Retirement Scheme investors (“ SRS Investors ”) should approach their respective CPF Agent Banks or SRS Operators to submit their votes at least seven (7) working days before the EGM (i.e. by 3.00 p.m. on 4 September 2025 ). CPF Investors or SRS Investors should contact their respective CPF Agent Banks or SRS Operators for any queries they may have with regard to the appointment of proxy(ies) for the EGM.

• Members who wish to exercise their voting rights at the EGM may:

• (a) (where the Member is an individual) attend and vote at the EGM; or

• (b) (where the Member is an individual or a corporate) appoint a proxy(ies) to vote on their behalf. The instrument appointing a proxy(ies), duly completed and signed, must be submitted to the Company in the following manner:

• (a) if submitted by post, be lodged at registered office of the Company at 42E Penjuru Road, Mencast Central, Singapore 609161; or (b) if submitted electronically, be submitted via email at ir@mencast.com.sg, in either case, by no later than 3.00 p.m. on 13 September 2025 (being not less than forty-eight (48) hours before the time appointed for the EGM). The accompanying Proxy Form for the EGM may be accessed via the Company’s corporate website at https://www.mencast.com.sg/, and will also be made available on the SGX website at https://www.sgx.com/securities/company-announcements. Members are strongly encouraged to submit completed Proxy Forms electronically via email. A Member can appoint the Chairman of the Meeting as his/ her/ its proxy, but this is not mandatory.

If a Member wishes to appoint the Chairman of the EGM as proxy, such Member (whether individual or corporate) must give specific instructions as to voting for, voting against, or abstentions from voting on, each resolution in the instrument appointing the Chairman of the EGM as proxy. If no specific direction as to voting or abstentions from voting in respect of a resolution in the form of proxy, the appointment of the Chairman of the EGM as proxy for that resolution will be treated as invalid.
