While cost-cutting is often the focus, research shows that only 30% of synergies come from cost reductions, while 70% are revenue synergies like cross-selling and market expansion. Revenue synergies, though harder to quantify and execute, often drive higher long-term value than initial cost savings. For example, McKinsey found that companies focusing on revenue synergies achieve 1.5x higher total shareholder return (TSR) compared to those focusing solely on cost synergies.
