• Develop 100-day integration and transformation plans, outlining synergy opportunities, platform consolidation pathways, and clear routes to value creation.
• Conduct rapid value-creation diagnostics, identifying operational constraints, performance gaps, and cost optimisation levers, and designing actionable plans to capture benefits at speed.
• Work in multidisciplinary teams and work closely with other EY service lines, partnering with financial, operational, and commercial due diligence teams to deliver cohesive, end-to-end insights that integrate technical, commercial, and financial perspectives for clients.
