Direct answer
A Confidential Information Memorandum (CIM, also called an Offering Memorandum or OM) is the document a seller provides to qualified buyers after they sign an NDA. It typically runs 25-60 pages and presents the business, its financials, its operations, its market position, and the transaction opportunity. The CIM is the marketing document that determines which buyers move from interest to LOI. Done well, it generates multiple competitive offers. Done poorly, it kills a process before it starts.
What the CIM does
The CIM converts a curious buyer into a qualified bidder.
Buyers who have signed an NDA need enough information to decide whether to submit an LOI. Too little and they cannot make a decision. Too much and they overload on detail. The CIM threads that needle — comprehensive enough to support an informed offer, not so detailed that diligence becomes redundant.
Standard CIM sections
A well-built CIM follows a recognizable structure that sophisticated buyers expect.
- Executive summary (2-3 pages). Key highlights: business description, financials, transaction overview, why this business and why now.
- Business overview (5-8 pages). History, products or services, customers, competitive positioning, key differentiators.
- Financial summary (5-8 pages). Three years historical revenue, gross profit, EBITDA or SDE, with add-back schedule. Year-to-date current year. Quality of earnings context.
- Operations (5-10 pages). Facilities, equipment, personnel, customer concentration, supplier relationships, technology stack.
- Market and growth (3-5 pages). Industry context, growth drivers, identified opportunities under new ownership.
- Transaction details (2-3 pages). Asking price (sometimes), preferred deal structure, transition expectations, process timeline.
- Appendices. Detailed P&L, organizational chart, customer concentration breakdown, capex history.
What a good CIM gets right
- Honesty about weaknesses. Every business has weaknesses. Acknowledging them in the CIM builds trust. Concealing them blows up in diligence.
- Defensible add-backs. The financial section presents SDE or adjusted EBITDA with each add-back documented. No magic numbers.
- Specific growth opportunities. Generic "growth potential" language is meaningless. Specific opportunities (this customer segment, this geography, this product extension) are credible.
- Right level of detail. Enough for a buyer to make a real decision. Not so much that diligence is duplicative.
- Visual presentation. Professional layout. Charts that clarify rather than decorate. Photos where appropriate.
What a bad CIM gets wrong
- Marketing hype. "Industry-leading," "best in class," "tremendous opportunity" — generic language reduces credibility.
- Inflated add-backs. Aggressive add-backs that will not survive diligence destroy trust.
- Unsupported growth claims. Hockey-stick projections with no underlying basis.
- Concealing concentration. Customer concentration that the CIM downplays but diligence reveals.
- Format and presentation issues. Sloppy layout signals sloppy operations.
The CIM and confidentiality
The CIM should be specific enough to inform a buyer but careful about identifying details that could leak.
Standard practice is to send a "blind teaser" first (1-2 pages, no identifying details) to gauge interest. Buyers who express interest sign an NDA, then receive the full CIM. Even the full CIM may redact specific identifying information (named customers, specific contract terms, exact employee names) until the buyer reaches a later stage.
How long does the CIM take to build?
A proper CIM takes 4-8 weeks of advisor and seller time to build well.
Most of the work is data gathering, financial recasting, and operational documentation. The writing itself is a smaller portion. Rushing the CIM is one of the most common sell-side mistakes — a one-week CIM tells buyers everything they need to know about the rest of the process.
Frequently asked questions
Do I need a CIM if I am selling to a known buyer?
If the buyer is fully informed and the transaction is straightforward, possibly not. But for any process involving more than one potential buyer, a CIM creates consistency in what each buyer sees and how they evaluate the opportunity.
Can I write my own CIM?
Possible, but rarely advisable. Sophisticated buyers can recognize an owner-written CIM versus an advisor-written one. The differences in presentation, financial presentation, and market positioning are visible.
How long is a typical CIM?
25-60 pages for a $1M-$5M business. Larger or more complex businesses can run longer. The goal is comprehensive but not exhausting.
Should the asking price be in the CIM?
Depends on the process. Some advisors include an asking price; some omit it to encourage best-and-final buyer pricing without an anchor. The decision depends on buyer pool and seller goals.
How do I know if a buyer has actually read the CIM?
Their questions reveal it. Buyers who have read the CIM ask specific questions about specific sections. Buyers who have not read it ask questions the CIM already answered. The latter is a warning sign.
