Why do most M&A deals fail to create value, and what can an acquirer do to improve the odds?
A core M&A Advisory interview question — asked in analyst and associate interviews across IB, PE, and the Big 4.
THE SHORT ANSWER
Studies show 50-70% of deals destroy value. Key reasons: overpaying (due to hubris or auction dynamics), poor integration (culture clash, loss of key talent), overestimated synergies, and strategic misalignment. To improve odds: rigorous due diligence, realistic synergy estimates, disciplined valuation with a margin of safety, detailed integration planning pre-close, and retaining key management. Also, consider earnouts to align incentives and bridge valuation gaps.
