Expert Session Preparation for Due Diligence: Maximizing External Insights

Expert sessions connect deal teams with industry practitioners, former executives, and sector specialists who provide context that financial data alone cannot deliver. In financial due diligence, expert insights help validate assumptions, identify risks, and calibrate the commercial reasonableness of management's narrative.

Transaction Services teams increasingly participate in or support expert sessions, particularly when the analysis raises questions that require industry context to resolve.

When Expert Sessions Add Value

Not every deal benefits from expert sessions. They are most valuable when the Transaction Services team encounters unfamiliar industry dynamics or sector-specific accounting treatments, management's narrative about growth, margins, or competitive position needs external validation, specific adjustments require industry context (e.g., whether a cost item is truly non-recurring or an industry norm), or the buyer is entering a new sector and needs to calibrate their understanding of operating norms.

For sector-focused teams that routinely handle retail, SaaS, or energy deals, the need for expert sessions may be lower because the institutional knowledge exists within the team. For general-practice teams or novel sectors, expert sessions fill critical knowledge gaps.

Preparation Framework

The value of an expert session is determined before the call starts. Unprepared sessions produce generic industry commentary. Prepared sessions produce specific, actionable insights.

Define the questions: Start with the specific analytical questions the team needs answered. These should flow from the financial analysis, not from general curiosity about the industry.

Examples of well-defined expert session questions:

  • "Is a 45% gross margin sustainable for a mid-market player in this segment, or is the target benefiting from temporary pricing dynamics?"
  • "What is the typical customer retention rate in this industry? Management claims 95% but our cohort analysis shows 88%."
  • "Are the regulatory changes announced last quarter likely to increase compliance costs materially? Management has not budgeted for additional spend."
  • "What is the standard sales cycle length? Management's revenue pipeline assumptions imply a 60-day cycle but we see 90+ days in the data."

Provide context to the expert: Share enough background (without disclosing confidential deal information) for the expert to understand what you are investigating. A statement like "We are analyzing a mid-market provider in segment X with $80M revenue, assessing the sustainability of their margin profile" gives the expert sufficient context to calibrate their responses.

Identify the right expert profile: Match the expert to the question. A former COO of a competitor can speak to operational norms. A former customer can validate the value proposition. A regulatory specialist can assess compliance risk. An industry analyst can provide market sizing and trend data.

Structuring the Conversation

A 60-minute expert session should follow a structured format.

Context setting (5 minutes): Brief the expert on the scope of the discussion without revealing the target's identity (unless explicitly authorized). Establish ground rules on confidentiality.

Key questions (40 minutes): Work through the prioritized question list. Start with the highest-priority questions. Allow the expert to elaborate where they offer unexpected insights. Be prepared to follow tangents if they reveal relevant information, but manage time to ensure core questions are covered.

Validation and calibration (10 minutes): Present specific data points or ranges (anonymized) and ask the expert to validate or challenge them. For example: "In your experience, is a 20% EBITDA margin typical, high, or low for a business of this size in this segment?"

Wrap-up (5 minutes): Confirm key takeaways, identify any follow-up questions, and determine whether a second session would be valuable.

Integrating Expert Insights into the Analysis

Expert insights must be translated into concrete analytical actions.

Adjustment validation: If an expert confirms that a cost item identified as non-recurring is actually an industry norm, the EBITDA adjustment should be removed or reclassified. Document the expert's view as supporting evidence.

Risk factor identification: Expert-identified risks that were not visible in the financial data should be flagged in the report. For example, an expert might identify pending regulatory changes, emerging competitive threats, or technology shifts that affect the target's forward outlook.

Commercial reasonableness: The expert's view on market growth rates, pricing trends, and competitive dynamics provides a benchmark against which management's projections can be assessed. If management projects 15% annual growth in a market the expert describes as growing at 5-8%, the gap needs explanation.

Benchmarking context: Expert-provided benchmarks for margins, working capital metrics, and capex intensity help calibrate the diligence findings. This context strengthens the quality of earnings report by providing external reference points for key conclusions.

Documentation and Knowledge Capture

Session notes: Document expert sessions thoroughly, including the expert's background, key statements, areas of confidence, and areas of uncertainty. These notes become part of the diligence record.

Knowledge retention: Expert insights contribute to the team's sector knowledge base. The observations and benchmarks from expert sessions on one deal inform the analysis of future deals in the same sector. This is a form of deal knowledge retention that compounds over time.

Limitations acknowledgment: Expert opinions are individual perspectives, not definitive facts. Document the expert's potential biases (former competitor, former customer, geographic focus) and note where multiple expert views converge or diverge.

Cost-Benefit Consideration

Expert sessions typically cost $500-2,000 per hour. On a deal with $50K-150K in advisory fees, two to three expert sessions represent a modest investment relative to the risk of missing a material issue. The return on investment is highest when sessions are well-prepared and targeted at specific analytical questions that the financial data alone cannot answer.
