Mergers and acquisitions (M&A)

Successfully achieving your deal objectives requires proactively identifying workforce issues with the same rigour as all other strategic elements. This includes evaluating the skills and behaviours required to make the deal work.

People expertise. Sustained performance.

Divestitures can unlock hidden shareholder value and generate cash to fund growth and innovation. Paying close attention to workforce risks can maximise sale price, increase speed of sale and enhance profitability.

Restructurings and turnarounds
Successful turnarounds require both financial restructuring and planned operational recovery. Aligning human capital strategy with strategic objectives is crucial for success.

Joint ventures and strategic alliances
Joint ventures and strategic alliances provide quicker results than building an entirely new business. They also appear to present less complex logistical challenges than acquisitions. Yet misaligned strategic goals, unclear governance, skewed operating models, indistinct workforce strategies and cultural mismatches can lead to underperformance.

Our focus

Heightened competition means buyers often have to commit without performing adequate due diligence, mitigating risk, determining compliance issues or fully developing post-merger integration plans. Mercer’s project management operations (PMO) approach combines world-class process management with real-time consulting. The result is the rapid identification and mitigation of risk.
