Dear Shareholders,

The Technology and Digitalization Committee (TDC) was formed on 15th May 2025 to oversee and guide the formulation of a strategic roadmap and execution aimed at transforming the Company's operations through appropriate and fit for purpose technologies and digital innovations. The TDC comprising three independent directors. All members possess relevant knowledge and work experience as well as a thorough understanding of the Group’s businesses and operations.

TDC has performed its duties in accordance with its charter and in line with current business priorities approved by the Board of Directors. In 2025, TDC convened a total of three meetings with attendance by all members. And has provided two reports (August and November) to the Board in 2025.

TDC’s key activities are summarized below:

1. TDC has assessed the Group’s status of digitalization, looking at the IT evolution of the Group from 2014 to 2025, and understands the complexity and environment of the Group. Recommendations and observations include:
   1. Cutting down/limiting software customization: Overly customized software potentially leads to difficult/costly maintenance and update.
   2. SAP reliance: Too much focus on SAP means that unstructured data and certain processes which are not on SAP may get left out and underdeveloped.
   3. Commercial first: Adoption of technology should be dictated by the Group’s business needs first. Tech should not be adopted solely for advancement’s sake.
2. TDC recommends the “Plan and Do” framework, with 2025 being the Plan phase, and 2026 being the Do phase:

   2025 – Plan: TDC is doing the impact assessment and the required capital linked into the CAPEX plan for Group digitalization efforts, with selected pilot projects that should yield favorable results quickly. TDC recommends that every BU has in their strategic plan a chapter dedicated to potential use of AI and digitalization in improving their operation.

   2026 – Do: TDC recommends that 2026 is the year where implementation starts, and all digitalization efforts Group wide will start to materialize in 2026 including but not limited to implementation of GenAI in procurement.

3. TDC has assessed and reviewed the requirements of (1) Enterprise-wide Digital Transformation Roadmap, and (2) Digital Procurement Transformation. Several leading service providers were assessed following a robust and objective procurement process reviewing the following key aspects: (a) technical capabilities, (b) customer feedback, (c) quality of proposal, and (d) commercial terms.
4. TDC has reviewed several aspects of an enterprise digital roadmap:
   1. Operations/ Manufacturing: Following the visit to a leading Chinese cement and technology provider, discussions with technology owners and experts, each operating company has defined 3-5 years roadmaps on technology investments.
   2. Commercial and Logistics: Most important is the review of current business processes in both commercial and logistics before implementing any new applications and technologies.
   3. Applications and AI: Data architecture, governance and the early adoption starting with the top management as the key enablers of transformation
   4. AI Adoption: Training and awareness was conducted for more than 1,133 users across the group, including several sessions to TMLs and BU EXCOs. Natural language processing AI (NLP) is currently being used and adopted at TH Commercial and Logistics.
   5. GenAI Technology Guideline: A best practice AI guideline has been developed and incorporated into an e-learning program to help users comply with the guidelines
   6. SAP S4/HANA: Go-live of S4/ HANA technical upgrade on 16 Nov 2025, 12:00 BKK
