What Is a Confidential Information Memorandum (CIM) in Private Equity
A confidential information memorandum is the sell-side bank's book on a company for sale. A buyout associate reads it after the NDA. It is long enough to support a first-round bid and optimistic enough that treating the numbers as proven is how a file gets dishonest.

A confidential information memorandum is the sell-side bank's book on a company for sale. A private equity associate reads it after the firm signs a non-disclosure agreement (NDA). It is long enough to support a first-round bid and optimistic enough that treating the numbers as proven is how a leveraged buyout (LBO) file gets dishonest.
The book usually runs 50 to 100 pages. Bankers also call it an offering memorandum or an information memorandum. Those names collide with a different document: the private placement memorandum a general partner uses to raise a fund. The banker book is about a company for sale. The fund document is about a partnership you are being asked to join.
Open investing seats sit on Private Equity Jobs. Firm names sit in the companies directory.
What a confidential information memorandum is
The bank has the mandate. Management has given the bankers the numbers, the customer story, and the reason for a sale. The bankers turn that into a book whose job is to get indications of interest. The bank is paid as a function of price. The book is written accordingly.
The memorandum is not a pitch book. A pitch book is the bank selling itself to the seller before anyone is hired. The CIM is what goes out once the seller has hired the bank. It is not a contract. Nothing in it binds the buyer to bid or the seller to sell. It does not print a valuation. The bank would rather let buyers bid than put a ceiling on the process.
Debt processes use a similar book. A debt information memorandum spends more pages on proposed terms (rate, floor, maturity, covenants, use of proceeds) and less on a five-year growth case. An equity raise at a bank usually gets a shorter memo, not a 70-page CIM.
US books are still often Word. European books are more often PowerPoint. The associate's job does not change with the file type.
Teaser, NDA, CIM, and the first bid
The teaser goes out first. It is short, often one to ten pages, and it does not name the company. No NDA is required. Its only job is to test whether a buyer wants more.
If the teaser fits the mandate, the fund negotiates the NDA. The NDA is what makes the next file confidential. It usually restricts use of the information, hiring from the company, and talking about the process. Competitors still sign them. The NDA is a filter, not a guarantee.
The CIM follows the NDA. The company's name is now on the cover. The associate has enough to build a first operating case and a first LBO, and not enough to underwrite. First-round bids in a formal auction are usually an indication of interest: a range, a structure, a financing sketch, and a list of what still has to be proved. A letter of intent comes later, often with a price, exclusivity, and a path into confirmatory due diligence.
The short list then sees a management presentation and a virtual data room. Quality of earnings accountants arrive after the book, not inside it. The investment-committee memo is a different document again. It is the fund's recommendation, not the bank's marketing.
A middle-market shop sees more of these books than a megafund. Volume is the point of a process. Forwarding every one upward burns the firm's reputation with the desk that sent it.
What is in the book
Structure varies by bank and by company. Most books still run through the same sections. The associate does not read them in order.
| Section | What the bank is doing | What the associate uses it for |
|---|---|---|
| Executive summary / investment highlights | Frame why this is a good time to buy | Mandate screen: size, sector, what the company actually does |
| Company overview | History, locations, legal entities, segments | Organic versus acquired growth; carve-out dependencies |
| Products and services | Capabilities and differentiation | Pricing power, switching costs, whether "platform" is a slogan |
| Market and competition | TAM, growth rates, ranked peers | Whether the market definition was chosen to make the company look large |
| Customers and sales | Logo wall, "blue chip," retention language | Concentration, contract term, competitive rebid, channel risk |
| Operations | Plants, systems, headcount | Capital intensity, key-person risk, whether a stand-up is still required |
| Management | Bios and an organization chart | Who stays, who is the founder, whether there is a second layer |
| Financials (history and projections) | Adjusted EBITDA, a growth case, sometimes a bridge | The first model. History first. The forecast last. |
| Risk factors | Often short, sometimes omitted | What the bank already knows can go wrong |
| Appendices | Segment tables, contracts summary, org detail | Where concentration and add-backs sometimes hide |
Some books add a transaction overview (stock versus asset, timing, what the seller wants). Some add an employee pyramid or a revenue cut by geography and product. A SaaS book should show annual recurring revenue, churn, and cohorts if it wants a software multiple. A manufacturing book should show capacity, capital expenditure history, and plant footprint. A healthcare book should show payer mix and licenses. Figures in the summary have to match the financial tables. If those cuts are missing, that is information.
Earnings before interest, tax, depreciation and amortization (EBITDA) in the book is almost always adjusted. The bridge is the most contested page. Owner compensation that will not be paid to a replacement is a real add-back. A "one-time" system implementation that ran two years in a row is not. New-logo revenue that has not been contracted is a forecast, not an earning.
What the CIM leaves out
The book is curated advocacy. It is not an audit and it is not the data room. The useful read is often the silence.
It rarely names revenue by customer. Banks like a page of customer logos. That page does not show what share of revenue sits with the top accounts. If the summary says "diversified" and the appendix does not show the top ten as a share of revenue, assume concentration until the data room proves otherwise.
It rarely shows true free cash flow. EBITDA minus capital expenditure is a two-minute proxy. Working capital, cash taxes, and the gap between maintenance and growth capex still have to be built. If free cash flow does not track EBITDA, leverage capacity is smaller than the margin page implies.
It does not contain a quality of earnings report. Add-backs, revenue cutoff, and whether "run-rate" is actually run-rate wait for accountants. It does not contain customer contracts, a legal review, tax exposures, or a working-capital peg. Those sit in the room, after a bid.
It does not set a price. It also does not always say why the owner is selling. "Next chapter" and "recapitalize for growth" are process language. The real reason (tired founder, lost customer, needed capex, a process the board started) shows up in diligence, or it does not, and that is a flag.
The most expensive silence is an add-back the bank has already capitalized. If the book adds back $2 million of costs and buyers are talking about 8.0x, that page is supporting $16 million of enterprise value. If diligence keeps only $0.5 million, the gap is $12 million before leverage and working capital. Credit sized on the same adjusted earnings has lent against cash flow that is not there.
The CIM has to match the data room. If the book claims high retention, the room needs cohorts, contracts, and churn. If it claims a cost add-back, the room needs payroll, invoices, or a board paper. A gap between the two is not a drafting miss. It is a diligence issue.
How a buyout shop reads a CIM
The associate does not start on page one and finish on page 80. The vice president will not thank them for a summary of a book that was dead on size.
First, kill on mandate. Sector the fund does not buy, revenue or EBITDA below the floor, a geography the partnership will not underwrite, a minority process when the fund only takes control, a customer book too concentrated to live with. That takes the executive summary and the first financial exhibit. Many books die here. That is the job.
If it survives, skip to the financials at the back. Historical revenue, margins, capital expenditure, and how closely cash tracks earnings. The forecast is the bank's best case. If a first-pass LBO does not clear the fund's internal rate of return (IRR) and multiple on invested capital (MOIC) hurdle on those numbers, it will not clear on a case the associate would actually underwrite. Stop.
If the math is plausible, read customers and the market. Why do customers pick this company. What share sits with the top account. Is growth organic or a roll-up the bank has already priced as if it were organic. Then management: who holds the relationships, who would leave, whether the second layer exists.
Each claim should become one of three things: a model input, a diligence question, or a risk flag. A useful log is the claim, the model line it hits, who has to prove it, and which file in the data room would settle it. A one-pager a partner can kill in a meeting is the product at this stage, not a 40-page recap of the bank's highlights.
Take an invented book. Northline Controls is a PEJ practice company, not a live deal. Trailing revenue $72 million. Reported EBITDA $11.2 million. Adjusted EBITDA $16.8 million. The bridge is $3.2 million of owner compensation, $1.4 million of "one-time" enterprise-resource-planning costs (year two of the same project), and $1.0 million of pipeline the company has not signed. The top customer is 28 percent of revenue, named only in an appendix. Capital expenditure ran $6.5 million against $3.8 million of depreciation. Management's case is 11 percent revenue growth and 100 basis points of margin expansion. History is 4 percent organic; the rest was tuck-in.
A fund that needs a mid-teens IRR on a five-year hold, at 5.0x leverage on adjusted earnings, will not get there at 11.0x adjusted. The $5.6 million of adjustments the associate does not believe are $62 million of enterprise value at that multiple. Cut the ERP add-back and the unsigned pipeline, replace owner compensation with a real hire, and the earnings base is closer to $12 million. Capex already eats the cash that was supposed to pay down debt. The book can still be a platform conversation at a lower multiple if the partnership buys roll-ups on purpose. It is not a standalone at the bank's implied clearing price. That is a 15-minute kill, written as a paragraph, not a model the partner did not ask for.
On a live LBO modeling test the prompt is sometimes a CIM extract. The test still wants a model another person can audit. The screen above is the judgment that decides whether anyone should open Excel.
CIM versus the other deal documents
| Document | Who writes it | When it shows up | What it is for |
|---|---|---|---|
| Teaser | Sell-side bank | Before the NDA | Anonymous test of interest |
| Pitch book | Bank, to the seller | Before the mandate | Win the assignment. Credentials, not the target. |
| Confidential information memorandum | Bank, with management | After the NDA | Enough to write a first-round bid |
| Confidential information presentation | Bank | Same window, often Europe | Shorter, slide-led version of the same case |
| Indication of interest | Buyer | After the CIM | Range, structure, what still has to be proved |
| Letter of intent | Buyer | After the IOI short list | Price, exclusivity, path into confirmatory work |
| Management presentation | Management, with the bank | Short-listed bidders | Live questions. The book is the written record. |
| Data room | Seller and advisors | After a serious bid | Source files. The CIM has to match it. |
| Quality of earnings | Accounting firm, for a buyer or the seller | Confirmatory diligence | Whether adjusted earnings are run-rate |
| Investment-committee memo | The fund (associate draft, VP rewrite) | Internal | Recommendation, not marketing |
| Private placement memorandum | The GP, raising a fund | Fundraising | The partnership you are asked to join, not a company for sale |
The CIM is the banker's case. The committee memo is whether the partnership would underwrite this price and this leverage. Mixing the two is how a file becomes a restatement of the highlights page.
Common questions
What does CIM stand for? Confidential information memorandum. In a sale process it is the long book buyers see after an NDA.
Is a CIM the same as an offering memorandum? In sell-side M&A, bankers use the names interchangeably. Outside M&A, offering memorandum often means a private placement memorandum for a fundraise. Ask which document you were sent.
Is the CIM a contract? No. The purchase agreement, the debt documents, and any letter of intent carry the terms. The book informs a bid.
Does the CIM include a price? Usually not. The bank wants bids, not a ceiling.
How is a CIM different from a teaser? The teaser is short and anonymous, before the NDA. The CIM is the named book after the NDA.
How is a CIM different from a letter of intent? The CIM is the seller's marketing. A letter of intent is the buyer's proposed terms. One is not a substitute for the other.
Can you trust the numbers? Treat them as claims. History is more usable than the forecast. Adjusted EBITDA is a claim until quality of earnings. Build a case you would underwrite, not the bank's case.
What should a buyout associate read first? Mandate fit in the summary, then the financials, then free cash flow versus EBITDA, then customers, then management. Many books should die before the market chapter.
Who writes it? The sell-side bank drafts. Management owns the facts and has to defend them in the management meeting. Counsel reads the NDA and the risk language. The company, not the analyst who formatted the book, is accountable for what it says.
