A disciplined, specialist-driven market shaped by regulatory resilience, selective investment and rising expectations around AI execution.
Market Overview: A More Disciplined, Specialist‑Focused Consulting M&A Landscape
The second half of 2025 revealed a consulting M&A market characterized by lower volumes but sustained, high‑conviction investment. Total disclosed spend surpassed $3bn, significantly above H1 levels, despite a notable decline in transaction count. This divergence signals a market where buy‑side precision, not broad activity, is setting the tone.
As discretionary transformation budgets remained cautious, acquirers increasingly differentiated between generalist advisory models and firms offering sector depth, regulatory resilience and credible AI integration. In consulting, specialization has become decisive — the core organising principle shaping buyer priorities.
Key Themes Shaping H2 2025 Consulting M&A
1. Selective Volumes, Strong Capital Deployment
Consulting deal activity softened significantly in H2, falling 23% from H1 and 34% year‑on‑year.
Yet capital deployment rose, with August and December alone contributing nearly $3bn in value.
This pattern reflects:
- A flight to quality
- Buyers backing scaled, defensible platforms
- Greater conviction in regulated and specialist segments
The market is not retreating — it is tightening.
2. Regulated and Compliance‑Driven Segments Lead Demand
Buyer interest concentrated in the most durable areas of consulting:
- Healthcare advisory
- Government and public sector
- ESG consulting
- Risk, compliance and financial services
These segments continue to attract steady sponsor attention even as discretionary consulting budgets remain cautious.
3. AI: From Narrative to Proof
By late 2025, AI had become a universal talking point in consulting.
But buyers have grown more discerning, asking:
“How is AI actually improving delivery economics?”
Acquirers prioritised firms that could demonstrate:
- Internal productivity gains from AI
- Agentic or automation capabilities
- Measurable client value creation
AI is now a margin story, not a marketing story.
4. From Billable Hours to Platform‑Enabled Models
Consulting is undergoing a structural shift away from pure time‑and‑materials economics.
Leading firms are increasingly monetising:
- Proprietary data
- Analytical platforms
- Managed services
- Recurring service models
Buyers value repeatability, defensibility and non‑discretionary revenue streams, particularly in a slower‑growth macro environment.
5. Quality Dispersion Widens
The gap between high‑quality and generic assets widened further in H2:
- Specialist firms saw competitive buyer interest and sustained valuations
- Generalist and broad‑brush advisory firms faced a tougher environment
Clarity of positioning now matters more than scale.
6. ESG Consulting Continues Consolidation Despite Growth Headwinds
ESG consulting recorded another record year for transactions.
Fragmentation and regulatory tailwinds continue to drive consolidation, even as organic growth in some ESG subsegments moderates.
What This Means for 2026
The consulting market is not in decline — it is rebalancing.
Buyers are pursuing:
- Defensible niches
- Regulatory‑anchored revenue
- Demonstrable AI integration
- Sector‑specific expertise
- Platform‑enabled delivery models
For founders and investors, the message is clear: consulting M&A now rewards depth, durability and clarity — not generalism.
