What is a CIM in investment banking?
Updated November 1, 2026
A confidential information memorandum (CIM) is the marketing document an investment bank writes when it sells a company. Buyers get it after signing a non-disclosure agreement. It describes the business, its market, management and financials, often in 50 or more pages, but it doesn't state a price.
What is a CIM in investment banking?
A CIM is the sell-side bank's detailed profile of the company for sale, written to make it attractive to buyers. Mergers & Inquisitions describes it as part of the sell-side M&A process, also known as an offering memorandum or information memorandum, usually 50+ pages (Mergers & Inquisitions). CFI calls it a marketing document whose goal is to sell for the highest value (CFI).
Banks also write CIMs for debt deals and for distressed sales, but not usually for equity offerings (Mergers & Inquisitions).
What's in a CIM?
A CIM usually covers the investment highlights, the business, the market, management and the financials, with projections. The order varies by bank. A typical outline, combining the lists from Mergers & Inquisitions and CFI:
- Executive summary and investment highlights: what the company does, key financials and why a buyer should care.
- Products and services: what it sells and how it makes money.
- Market overview: market size, growth, competitors and the company's position.
- Customers and sales and marketing: customer mix, concentration and how it sells.
- Management and employees: the leadership team and the workforce.
- Financial results and projections: historical statements and management's forecast, with assumptions.
- Risk factors and appendices: sometimes left out.
Debt CIMs add the proposed terms, such as rate, maturity and covenants, and the use of funds (Mergers & Inquisitions; CFI).
What a CIM is not: a binding contract, a valuation, or a pitch book. Banks leave price out so buyers' bids set it, and a pitch book is what the bank uses to win the mandate in the first place (Mergers & Inquisitions).
When is a CIM sent in a sell-side M&A process?
After the teaser and the NDA, at the start of the first round. Interested buyers sign the NDA, receive the CIM, and return non-binding indications of interest that the bank uses to shortlist bidders (Wall Street Prep; Datasite).
| Step | What happens | Main document |
|---|---|---|
| 1. Teaser | The bank sends a short, no-names summary to potential buyers | Teaser |
| 2. NDA | Interested buyers sign a non-disclosure agreement | NDA |
| 3. CIM | Buyers who signed get the full profile of the company | CIM |
| 4. Indications of interest | First-round, non-binding bids, used to narrow the buyer list | Indication of interest (IOI) |
| 5. Management presentations | Shortlisted buyers meet management and get data room access for diligence | Management presentation, data room |
| 6. Final bids | Remaining buyers submit final bids, often as letters of intent; the seller picks a winner and negotiates | Final bid letter, LOI, purchase agreement |
Wall Street Prep's example timeline gives about 4 to 6 weeks each for preparation, round one and round two, and 6 to 8 weeks for negotiation (Wall Street Prep). Sources describe the binding status of letters of intent differently: Midaxo calls them binding bids (Midaxo), while CFI says an LOI is mostly non-binding except for terms such as exclusivity and confidentiality (CFI).
In an exclusive negotiation with one buyer, the steps are looser and there may be no CIM at all (Wall Street Prep).
Who writes a CIM, and what do analysts do on it?
The sell-side bank writes it, with information from the company's management. CFI says the banker's first step is gathering information from top management to build the company profile (CFI).
Analysts do much of the drafting. Mergers & Inquisitions says a lot of it is copying and adapting material from the client and industry reports, and most of the thinking goes into two sections: the executive summary and investment highlights, and the financial performance section, where results are presented favorably without misstating them (Mergers & Inquisitions).
- Collect financial statements, operating data and management information (Datasite).
- Draft sections and pull market data from research sources (CFI).
- Build the buyer list and track who has signed NDAs and received the CIM (Datasite).
- Check every number against the model and the source files.
On the buy side, private equity analysts read many CIMs and screen most deals out quickly, often starting with the summary and the financials (Mergers & Inquisitions).
What is the difference between a CIM, a teaser and a management presentation?
The teaser is short and anonymous, the CIM is long and detailed, and the management presentation is a live meeting with shortlisted buyers.
| Teaser | CIM | Management presentation | |
|---|---|---|---|
| When | First contact, before the NDA | After the NDA, round one | Round two, after indications of interest |
| Length | 1–2 pages (CFI); Mergers & Inquisitions also describes 5–10-page versions | Often 50+ pages | A slide deck and a meeting |
| Names the company? | No, written on a “no-names” basis | Yes, under the NDA | Yes |
| Purpose | Gauge and generate interest | Give buyers enough to submit a first bid | Let buyers question management directly |
Sources: CFI on teasers; Mergers & Inquisitions on CIMs; Midaxo. Mergers & Inquisitions says management presentations are essentially extended versions of the CIM, and that in Europe CIMs often look more like presentations than written documents (Mergers & Inquisitions).
How does the CIM come up in investment banking interviews?
Usually as part of a process question, such as “Walk me through a sell-side M&A process” or “What does an analyst do on a live deal?” Name the steps in order, say where the CIM fits, and mention one analyst task on it.
- “What's the difference between a teaser and a CIM?” Length, anonymity and timing relative to the NDA.
- “Why doesn't a CIM include a valuation?” The seller wants bids, not an anchor price.
- “If you got a CIM as a PE analyst, what would you look at first?” What the company does, its size, then growth, margins, CapEx and cash flow conversion.
The follow-ups are often technical: how a buyer would value the company or whether a deal is accretive. Practice those in the merger model questions and valuation questions. For which teams run sell-side processes, see investment banking groups.
