The Confidential Information Memorandum (CIM) — also called an offering memorandum (OM) or simply the information memorandum — is the principal marketing document in a sell-side process. Where the teaser is a one-page tease, the CIM is the full prospectus for the business: typically 30 to 80-plus pages giving a buyer everything needed to form a preliminary view and submit an indication of interest. It is released only after a buyer signs an NDA.
What a CIM contains
A standard CIM is organized into a predictable set of sections:
- Executive summary — the investment thesis and key highlights.
- Business overview — products and services, history, locations, operations.
- Market and industry — size, growth, competitive landscape, the company's position and moat.
- Customers and suppliers — concentration, relationships, contract terms.
- Management and employees — organization chart, key people, headcount.
- Financial information — three to five years of historicals plus a management projection, presented on an adjusted / Adjusted EBITDA basis.
- Growth opportunities — the levers a buyer could pull (new markets, cross-sell, add-ons, pricing).
- Transaction overview — what is for sale and the process timetable.
A marketing document, not an audit
The CIM is written by the seller's adviser to present the company in its best honest light. Projections are management's, add-backs are the seller's case, and the narrative emphasizes strengths. Sophisticated buyers therefore read a CIM as an argument to be tested, not a set of facts to be accepted — every material claim is later checked in diligence, and the Adjusted EBITDA is re-examined by a quality-of-earnings (QoE) analysis. Advisers are nonetheless careful that the CIM be accurate and not misleading, because material misstatements can become indemnification or even fraud exposure later.
How buyers use it
From the CIM a buyer builds its preliminary valuation — an EBITDA multiple sanity-checked against a DCF and, for financial buyers, an LBO model — and decides whether and at what range to bid in its IOI. Short-listed buyers then deepen their understanding through the management presentation and the data room.
The "CIM" in modern small-cap deals
In lower-middle-market and broker-led deals, the document may be shorter (a 10–25 page "CBR" or confidential business review) but serves the same role. As deal size rises, CIMs grow longer, more designed, and more heavily lawyered.

- Teaser — A one-to-two-page anonymous summary used by sell-side advisors to introduce a target to potential buyers without disclosing its identity until an NDA is signed.
- Non-disclosure agreement — A confidentiality contract executed before a buyer receives the CIM. It binds the buyer to use the target's information only to evaluate the transaction.
- Data room — A secure repository (today, almost always virtual) where the seller posts due-diligence documents for buyer review. Access is staged by deal phase and bidder identity.
- Indication of interest — A non-binding, written response from a buyer giving a preliminary valuation range, structure preferences and key conditions. Used to short-list bidders before LOIs.
- Sell-side M&A process — The deal cycle from the seller's perspective: preparation, marketing materials, buyer outreach, IOIs, LOIs, exclusivity, due diligence, definitive agreement and closing.
- Quality of earnings — An independent accounting analysis that tests how sustainable, predictable and accurately measured a target's reported earnings are. The QofE is a near-universal pre-LOI deliverable in serious deals.
- Normalization adjustments — Adjustments to reported earnings to remove one-time, non-operating or owner-specific items, producing a run-rate EBITDA that better reflects the ongoing business.
