Complete M&A Process Guide: From Strategy to Integration in 2025
Global M&A deal values reached $2.5 trillion in 2023, down from $5 trillion in 2021, according to PwC Deal Trends—reflecting increased scrutiny, complex valuations, and longer due diligence periods. Meanwhile, Harvard Business Review research shows 70-90% of acquisitions fail to create shareholder value, often due to poor execution rather than strategy.
Peony streamlines M&A execution with secure data rooms: AI-powered organization structures due diligence materials automatically, granular access controls limit document visibility, complete audit trails document all activity, and page-level analytics show buyer engagement patterns. Purpose-built for M&A transactions.
Here's your comprehensive guide to executing successful mergers and acquisitions in 2025.
M&A Process Overview
The three phases:
Pre-Deal (3-6 months) - Strategy, target identification, valuation
Deal Execution (3-9 months) - Due diligence, negotiation, closing
Post-Deal (12-24 months) - Integration, synergy realization
According to Deloitte M&A research, average transaction timeline is 6-18 months from initial contact to closing.
Pre-Deal Phase
Strategic Planning
Why M&A? Define clear rationale before pursuing targets.

Strategic fit criteria:

- Acceptable risk profile
Avoid common traps:
- Acquiring to "keep up" with competitors
