What CIM Builder does

The CIM Builder skill is designed to facilitate the creation of Confidential Information Memorandums (CIMs) for sell-side mergers and acquisitions (M&A) processes. This skill helps users organize and structure company information into a professional document that is ready for investors. It provides a clear workflow that guides users through the necessary steps, ensuring that all critical information is included and presented in a cohesive manner.

The process begins with gathering essential source materials, including management presentations, historical financial data, and customer insights. Users are prompted to compile these inputs, which serve as the foundation for the CIM. The skill outlines a standard CIM structure, detailing the contents of each section, from the executive summary to the appendix. This structured approach helps users create a document that is not only comprehensive but also easy to navigate.

In addition to the structural guidance, the CIM Builder emphasizes the importance of tone, narrative, and data-driven content. It instructs users to maintain a professional tone while crafting a compelling story about the business. By focusing on growth potential, margin profiles, and defensibility, the skill ensures that users present their company in the best light without omitting material issues that buyers will uncover during due diligence.

Finally, the output is a polished Word document accompanied by an Excel appendix containing detailed financials, complete with embedded charts and exhibits. This ensures that the final CIM is visually appealing and informative, meeting the expectations of potential buyers in the M&A landscape.

When to use it

Use this skill when preparing sell-side materials for M&A processes, particularly when drafting a CIM.

When not to use it

This skill may not be suitable for users who need a quick, informal document or those unfamiliar with M&A processes.

CIM Builder

Workflow

Step 1: Gather Source Materials

Ask for available inputs:

  • Management presentations
  • Historical financials (3-5 years)
  • Budget/forecast
  • Company website and marketing materials
  • Customer data (anonymized if needed)
  • Org chart
  • Prior presentations or board decks
  • Quality of earnings report (if available)

Step 2: CIM Structure

Standard CIM table of contents:

I. Executive Summary (2-3 pages)

  • Company overview — what they do, why they win
  • Investment highlights (5-7 key selling points)
  • Financial summary — headline revenue, EBITDA, growth, margins
  • Transaction overview — what's being sold, indicative timeline

II. Company Overview (3-5 pages)

  • History and founding story
  • Mission and value proposition
  • Products and services description
  • Business model and revenue streams
  • Key differentiators and competitive advantages

III. Industry Overview (3-5 pages)

  • Market size and growth dynamics (TAM/SAM/SOM)
  • Key industry trends and tailwinds
  • Competitive landscape
  • Regulatory environment
  • Barriers to entry

IV. Growth Opportunities (2-3 pages)

  • Organic growth levers (new products, markets, pricing)
  • M&A / add-on opportunities
  • Operational improvements
  • Technology investments
  • White space analysis

V. Customers & Sales (3-5 pages)

  • Customer overview (number, segments, geography)
  • Top customer analysis (anonymized if pre-LOI)
  • Customer concentration and retention metrics
  • Sales process and go-to-market strategy
  • Pipeline and backlog

VI. Operations (2-3 pages)

  • Organizational structure
  • Key personnel
  • Facilities and geographic footprint
  • Technology and systems
  • Supply chain / vendor relationships

VII. Financial Overview (5-8 pages)

  • Historical income statement (3-5 years)
  • Revenue analysis — by segment, geography, customer type
  • EBITDA bridge and margin analysis
  • Balance sheet overview
  • Cash flow summary
  • Capital expenditure history
  • Working capital analysis
  • Management forecast / budget (if included)

VIII. Appendix

  • Detailed financial statements
  • Customer list (anonymized)
  • Product catalog
  • Management bios

Step 3: Drafting Guidelines

  • Tone: Professional, factual, compelling but not hyperbolic
  • Narrative: Tell a story — why this business is attractive, defensible, and positioned for growth
  • Data-driven: Support every claim with data. "Strong growth" → "Revenue grew at a 15% CAGR from 2021-2024"
  • Visuals: Charts and graphs for financial trends, market size, competitive positioning
  • Length: 40-60 pages total — enough detail to inform first-round bids, not so long buyers won't read it
  • Confidentiality: Include a disclaimer page. Anonymize sensitive customer data unless seller approves

Step 4: Output

  • Word document (.docx) with professional formatting
  • Separate Excel appendix with detailed financials
  • Charts and exhibits embedded in the document

Important Notes

  • The CIM is a sales document — lead with strengths, but don't hide material issues (buyers will find them in diligence)
  • Investment highlights should address the 3 things every buyer cares about: growth potential, margin profile, and defensibility
  • Financial normalization / pro forma adjustments should be clearly labeled and explained
  • Work with legal on the confidentiality disclaimer and any regulatory disclosures
  • Get management to review for factual accuracy before distribution
  • The CIM sets expectations on valuation — make sure the narrative supports the asking price
