What to Include in a CIM

A confidential information memorandum — the CIM — is the primary marketing document in a sell-side M&A process. What to include in a CIM is largely consistent across transactions: eight core sections that give buyers the operational context, financial history, and deal structure they need to form a preliminary bid. The specific depth and emphasis within each section changes by deal, but advisors who understand the standard framework can build a credible CIM for any business.

Why Section Completeness Matters

Buyers review dozens of CIMs each year. The documents that generate competitive processes are not necessarily the best-written ones — they are the most complete and most credible ones. A buyer who cannot find the financial data they need, cannot understand the market context, or cannot assess management quality will discount their bid or pass.

The eight sections below are not a template to fill mechanically. They are a framework for answering the questions every sophisticated buyer will ask before submitting a preliminary indication of interest. Advisors who understand what buyers are looking for in each section produce CIMs that close.

For the full section-by-section production workflow, see How to Write a CIM. For the structure of the section buyers read first, see What Goes in a CIM Executive Summary.

Section 1: Executive Summary

The executive summary is the most important section of the CIM. Buyers often form a preliminary view — continue or pass — based solely on what they read here. It must answer three questions immediately: what is this company, what are its financial highlights, and why is it an attractive acquisition?

Company snapshot. One concise paragraph describing the business: what it does, what markets it serves, and what makes it distinctive. This is not a marketing brochure — it is a precise description that lets buyers instantly categorize the opportunity.

Investment highlights. Three to five bullet points of the most compelling, factual reasons to acquire. These are not aspirational claims; they are supported by data in the body of the document. Common investment highlights include revenue retention rate, customer concentration profile, market position relative to peers, proprietary technology or data, and margin profile relative to sector benchmarks.

Financial summary table. The two-line financial summary that every buyer looks for immediately: revenue and EBITDA for the last two to three fiscal years, the LTM period, and forward projections. Present this as a clean table. Buyers anchor their preliminary valuation multiple from this data before reading further.

Transaction overview. A brief description of the deal structure (full sale, majority recapitalization, minority stake), management’s post-transaction intentions, and the high-level process timeline.

The executive summary should be readable in five to seven minutes. If a senior M&A professional cannot extract the investment case after reading it, the document has failed its primary function.

Section 2: Business Overview

The business overview gives buyers the operational context behind the financial results. Unlike the executive summary, which highlights the most compelling facts, the overview provides the foundational detail buyers need to model the business and assess risk.

Key sub-sections:

History and ownership. Founding year, key milestones, ownership structure, and prior M&A activity. Buyers want to understand how the business was built and who currently owns it.

Legal entity and structure. Corporate structure, key operating subsidiaries, jurisdictions, and any relevant regulatory licenses. This directly affects deal structure and timeline.

Products and services. What the company sells, how revenue is attributed across product lines or service categories, and what drives retention or repeat purchase. For multi-product businesses, include a revenue waterfall by line.

Customer profile. Who buys, how they are acquired, and — critically — how concentrated the customer base is. Revenue concentration is one of the first things buyers model into their risk assessment. If the top three customers represent 60% of revenue, say so directly and address it.

Go-to-market and distribution. How the company sells: direct sales, channel partners, inbound, referral. Include deal size and sales cycle length for B2B businesses. Buyers use this to assess scalability and post-acquisition growth vectors.

---

Section 3: Products and Revenue Model

This section goes deeper than the business overview on the commercial mechanics of the business. It is particularly important for complex businesses with multiple revenue streams.

Revenue model. How the company generates revenue: subscription, project, transaction, usage-based, or mixed. For each revenue type, include the financial profile: average contract value, duration, renewal rate, and gross margin.

Product detail. For each major product or service: what problem it solves, who the buyer is, how it is delivered, and its margin contribution. Keep this factual. Buyers will form their own views on defensibility — the advisor’s job is to present the facts clearly.

Pricing architecture. How the company prices its products or services, including any standard contract terms. Buyers assess whether there is room to expand margins post-acquisition.

Backlog and pipeline. For businesses with project revenue or long-lead-time sales, a contracted revenue backlog and qualified pipeline table materially affects buyer confidence in near-term financial forecasting.

---

Section 4: Market and Competitive Landscape

Buyers are acquiring a market position, not just a company’s current financials. The market section grounds the investment thesis in credible external data. It demonstrates that the market the business operates in is large enough, growing fast enough, and structured favorably enough to justify the acquisition premium.

Total addressable market. Use third-party market sizing from credible sources — Bain, McKinsey, Goldman Sachs, IBISWorld, industry associations. Management-estimated TAMs are treated with skepticism. A cited external figure with a reputable source is more credible than an optimistic internal calculation.

Market growth dynamics. The secular trends driving category growth: regulatory tailwinds, technology adoption, demographic shifts, or supply-demand imbalances. Frame these around data where possible.

Competitive landscape. A map of the competitive environment without naming specific companies. Use category descriptors: large strategic acquirers in the space, PE-backed platform companies, regional operators, new entrants. Describe the competitive intensity and the basis of competition — price, quality, relationships, speed.

Target’s competitive position. How the company sits relative to the landscape: what differentiates it, what creates switching costs or barriers to entry, and what customers would lose if they moved to an alternative. This is the section where the investment thesis is explicitly made.

Section 5: Financial Performance and Projections

The financial section receives the most scrutiny. Every number will be modelled, stress-tested, and interrogated during management presentations and diligence. Accuracy and presentation clarity are non-negotiable.

Historical income statement. Three to five years of revenue, gross profit, operating expenses, and EBITDA. Present figures as audited or reviewed where available; note clearly if they are management-prepared. Use consistent formatting across years.

Adjusted EBITDA bridge. The normalised earnings figure that buyers anchor their valuation multiples to. Start with reported EBITDA and add back one-time items, non-recurring costs, excess owner compensation, and pro forma adjustments. Each line of the bridge must be labeled, quantified, and explainable. Buyers will challenge every adjustment; defensibility matters more than size.

LTM and NTM summary. The trailing twelve months of financial performance and the next twelve months forward projection. These are the periods most buyers anchor their entry multiple to. Present them as a standalone table that mirrors the historical income statement format.

Revenue bridge. For businesses with meaningful organic growth, acquisitions, or customer mix shifts, a revenue bridge by component (price, volume, churn, new customer acquisition) helps buyers understand the durability of growth.

Key operating metrics. Metrics specific to the business model that the income statement alone does not capture: gross retention, net revenue retention, average transaction size, units sold, or whatever metrics the management team uses to run the business. These often explain the EBITDA trajectory more precisely than the P&L.

Management projections. A three-year forward model prepared by management with explicit, stated assumptions. Buyers will build their own model but use management’s projections as the baseline narrative. Overly optimistic projections without supporting assumptions erode credibility.

Section 6: Management Team

Acquirers are evaluating the people they will be partnering with or inheriting after closing. The management section must give buyers enough information to assess team quality and identify key-man risk.

Biographies. For each senior leader: relevant experience, tenure at the company, functional scope, and educational background. Keep bios factual and specific. Two paragraphs per executive is sufficient.

Organisational chart. A visual representation of the senior leadership team and reporting structure. Include headcount by function to give buyers a sense of the operational footprint.

Key-man analysis. If the business is materially dependent on one or two individuals, address it explicitly. A proactive narrative — the plan for knowledge transfer, succession, or retention — is always more credible than leaving the issue for buyers to discover in diligence.

Retention and incentives. Whether existing management plans to remain post-transaction and on what commercial terms. Management continuity significantly affects buyer confidence, particularly in services or relationship-driven businesses.

For a detailed look at what buyers assess in management presentations — the live equivalent of this section — see the glossary entry.

---

Section 7: Transaction Overview

The transaction section frames the deal itself. It answers the practical questions buyers need answered before moving into a structured diligence process.

Deal rationale. Why the seller is transacting now: shareholder liquidity, growth capital, succession planning, or strategic combination. Frame this from the seller’s perspective in terms that give buyers confidence that the seller is motivated and the process is genuine.

Proposed deal structure. Stock vs. asset sale (where relevant), expected deal size range, management rollover preferences, and any preferred transaction structure. Do not disclose a hard floor price; present structure preferences at a level that gives buyers directional guidance without anchoring them.

Regulatory considerations. Change-of-control clauses, licensing requirements, antitrust thresholds, or industry-specific compliance issues that buyers need to factor into timeline and structure.

Process timeline. The process letter governs the formal timeline, but the CIM should include a high-level schedule: first-round bid deadline, management presentation window, final bid deadline, and target signing date.

---

Section 8: Appendix

The appendix supplements the main body with supporting detail that is too granular for the narrative sections but too important to omit.

Common appendix items:

• Detailed customer list with revenue attribution (under NDA, available to qualified buyers at a later stage)
• Multi-year financial statements (complete P&L, balance sheet, cash flow)
• Detailed segment or product-line financial breakdown
• Key contract summaries or customer testimonials
• Facility or asset summaries for asset-heavy businesses
• Technical architecture overview for technology businesses
• Regulatory licenses and certifications

The appendix also serves a process function: items too sensitive to include in the main CIM — customer names, detailed margin data — can be flagged as available in the data room to qualified buyers after NDA execution.

What to Leave Out of a CIM

Experienced advisors are as disciplined about what to exclude as what to include.

Speculation. Projections should be grounded in evidence and stated assumptions. Aspirational targets without supporting logic erode the document’s credibility with sophisticated buyers.

Competitor names. Standard practice is to describe the competitive environment in category terms without naming specific companies. Naming competitors creates legal exposure and signals that the advisor lacks process discipline.

One-sided narrative. Buyers expect CIMs to present the business positively — that is the point. But a document that refuses to acknowledge any risk or weakness loses credibility. Address known issues proactively; buyers will find them in diligence regardless.

Premature pricing. The CIM should not include a specific asking price or valuation. The goal of the CIM is to generate preliminary indications of interest that reflect each buyer’s own view of value. See CIM vs Pitchbook for how deal marketing documents differ from internal advisory presentations.

How AI Changes CIM Production

The most time-consuming parts of CIM production are not the writing — they are the research, the comparable transaction analysis, the financial modelling, and the iterative management review cycles. AI tools built specifically for M&A workflows can automate the research and formatting pipeline that sits behind each of these sections.

Generic AI tools generate plausible-sounding content but lack the deal-comparable data, proprietary buyer databases, and M&A-specific training that advisory-grade production requires. For a detailed comparison, see Why General-Purpose AI Falls Short for M&A Pitchbooks.

Tools like Bookbuild are built on 332K deal comps and 120K buyer profiles — the kind of proprietary data that makes AI output useful in an actual M&A process rather than a generic AI response dressed in finance language. Request early access →
