With a steadfast commitment to our shared vision, bolstered by the support of our dedicated team and the expertise of our Board of Directors, we have successfully integrated, consolidated, and optimised our operations to achieve promising outcomes. By setting clear objectives and fostering collaborative efforts, we have accomplished our first-year milestones as planned. Guided by four fundamental pillars that underpin our corporate philosophy and strategic vision, namely Safety, People, Sustainability, and Profit, we reaffirm our commitment to excellence, innovation, and responsibility in all facets of our business operations. These pillars serve as the cornerstone of Wasco’s vision for the future, encapsulating core values that drive our decisions, actions, and aspirations as an organisation. Last year, we announced the retirement of Chan Cheu Leong and the appointment of Gian Carlo Maccagno as the new Managing Director/Group CEO. This transition in leadership and accompanied by the roll-out of a comprehensive transformation plan marked the beginning of a transformative journey. Significant progress has been achieved across all areas of growth, driven by strategic initiatives aimed at strengthening our core operations, exploring new market opportunities, and enhancing our overall competitiveness. Chairman and Managing Director/ Group CEO’s Statement 29 Wasco Berhad

Creating a Cohesive Wasco As part of our transformation journey, we have realigned and restructured our business into two main segments - energy and bioenergy. This strategic decision aims to enhance focus, streamline operations, and capitalise on emerging opportunities in these sectors. Additionally, we have strategically taken a decision to exit the trading business as it no longer aligned with the aspirations of the group going forward. Moreover, we have disposed non-core assets to optimise our portfolio and strengthen our financial position. Following the name change to Wasco Berhad on 31 May 2023, we intensified efforts to foster unity across our organisation at operational, personnel, and cultural levels. In line with the consolidation rationale, we streamlined support functions such as finance, procurement, contract management, IT, and human resources. Concurrently, we harnessed cross-functional synergies by leveraging our combined resources and cross-selling services while enhancing efficiencies through the sharing of best practices. Crucially, we fostered a new identity among our employees, accompanied by a shared vision, mission, and values. Various initiatives, including brand champion workshops, training sessions, and enhanced onboarding programmes, were undertaken to garner employee buy-in. These efforts were complemented by initiatives aimed at fostering unity, such as the establishment of common communication platforms, internal portals, virtual libraries, and town hall sessions.
