The Perfect Confidential Information Memorandum (CIM)

CIMs are the first full portrait of a company for sale that buyers see. As they say, you only get one shot at a first impression.

First, a Disclaimer

This article is about confidential information memorandums (CIMs) for mid-market companies, not the Fortune 1000. Public company CIMs are mostly compiled from information already widely available and from the analysts who follow them.

In contrast, the CIMs that mid-market M&A advisors create require them to request, format and analyze the meaning of raw private company data, normalize earnings for owner compensation, and answer many questions that large-cap CIMs don’t face — like what happens if the owner leaves, or if the advisor uncovers a tax problem? Wall Street investment bankers don’t persuade mid-market buyers, only relevant data does.

Introduction

Before M&A advisors take their sell-side clients to market — a decision covered in our When to Sell the Company article — they spend about three months preparing a confidential information memorandum (CIM) that describes the opportunity to buyers.

(As for what other things advisors do in those three months, see our How M&A Advisors Sell a Company and Which to Use: M&A Advisor or Business Broker.)

Why does creating a CIM take three months or more? Why is it worth writing and what’s in it?

Below we answer those questions, and then we walk through the contents of a successful CIM we wrote including all sections  and examples of the most persuasive charts. Advisors distribute actual CIMs under NDA so they don’t see daylight: that’s why almost every online example you see is a generic outline. Not here.

About CIMs

The perfect CIM includes all the key information a buyer needs to decide whether it’s worth spending time investigating the company for sale in depth, perhaps meeting management and negotiating a letter of intent (for what’s in that, see The Perfect LOI). CIMs are distinct from offering memoranda (OMs): those are used in capital raises to describe minority investments in a company’s securities rather than to acquire control. See Investopedia’s OM description.

What Are CIMs For?

A number of things:

• To describe the company and its circumstances comprehensively yet concisely.
• To answer the questions that most buyers ask, this reducing tiresome, duplicative back-and-forth Q&A.
• To provide data that the advisor can then condense into a two-page, anonymized teaser that introduces the target to buyers. If buyers want to know more after seeing that, they’ll sign an NDA, and if the M&A advisor judges them capable and qualified to move ahead, they’ll receive a CIM.
• To, by its appearance and thoroughness, signal a professional approach to the M&A process.
• To present the seller in an attractive but fair light.
• To create an atmosphere of openness and trust.
• To help ensure confidentiality since, as mentioned, it’s distributed only to vetted buyers who signed NDAs.

What a Confidential Information Memorandum Contains

Subjects Covered

To accomplish the purposes above, the perfect CIM covers the following categories of target company information:

What CIMs Don’t Typically Cover

M&A advisors usually exclude details about the M&A process and highly sensitive company details. Examples include the due date for letters of intent (LOIs), deal team contact data and due diligence task assignments, company personnel files, supplier and client identities, legal matters, corporate books, tax records, trade secrets, M&A project “rules of the road,” and valuation arguments. All those live in a VDR (virtual data room), or in direct communication between the buyer’s and seller’s M&A advisors.

A Real CIM

What follows is the architecture of a CIM we wrote for the sale of a mid-market contract electronics manufacturer (EMS) that designed and assembled prototype printed circuit boards (PCBs) for makers of devices like smartwatches, electronic scales medical equipment and factory tools. We’ve removed names, geography, client identities along with absolute financial metrics while preserving the structure, analyses and exhibits. We’ll call this sell-side client “Chipmaker.”

Ten sections and four appendices, running about 60 pages.

Two things are worth noticing about this “T of C” list:

1. The Summary reproduces all the sections in miniature. So a buyer who reads only the first six pages gets the entire value argument but without all the supporting details. Many buyers only read summaries anyway.
2. The subsection titles in the Clients section aren’t neutral labels but rather assertions: “Sales Value per Client Steadily Rising,” “Gross Margins Widening as Revenues Grow,” “Strong Client Loyalty,” “Low Client Concentration.” Each one is a claim that the text below proves with data. That’s the difference between a CIM that looks like an advertising brochure and one that delivers evidence.

What the Analysis Actually Consisted Of

While a CIM’s table of contents tells you the topics, its exhibit list tells you about the business. The Chipmaker CIM carried thirty-eight exhibits across sixty pages — fourteen charts, nineteen figures and five tables. So it argued visually and used text to make points about value.

The figures covered:

• Market structure
• A full assembly process flow
• Sample components
• Five representative board types at increasing complexity
• Production equipment
• An organization chart, and
• Five financial exhibits:
  • Income statement
  • Ratios against industry
  • Net working capital
  • Balance sheet ratios against industry
  • Operating ratios against industry, and
  • A three-year pro forma.

The tables covered:

• Corporate history
• Service offerings
• Top clients by industry
• Competitors, and
• Projection job volumes.

The charts of data did the heavy lifting, and we reproduce four of them below.

A Closer Look at the Clients Section

If a buyer is going to sign an LOI or walk, that decision often happens here. The Clients section of Chipmaker’s CIM ran eight pages and made six arguments in sequence, each with its own data.

Geographic reach is widening
The company had steadily reduced its reliance on nearby accounts, and for the first time in the year before the sale it earned less than half its revenue from the West.

Reliance on the West fell from 64% to 45% over five years as the company
won work further afield.

Client value is rising
Both median and average annual order value per client grew year over year. Across five years, order value per client compounded at better than 20% annually while the client count stayed roughly flat — a growth story about depth rather than acquisition.

Clients themselves are getting bigger
Management tracked client revenue, not just its own. Large clients raised their share of company sales by more than twenty points over three years, displacing smaller accounts.

Large clients grew from a third of sales to slightly more than half, evidence
the company was moving upmarket.

Margins widen as revenue grows
Gross margin improved by roughly seven points across five years, attributed to learning-curve gains and production economies of scale.

Loyalty is quantified and strong
Half of final-year revenue came from clients acquired before the period began, with four later cohorts stacked on top.

Cohort analysis of the kind more common in software CIMs than
manufacturing ones. It shows retention and new-business momentum in
a single image.

Concentration risk is low
No single client or industry could take the business down, and the segments growing fastest were not the ones the company most depended on.

Segment growth rates over five years. Two segments were shrinking; the
CIM said so rather than burying it.

This sequence of exhibits anticipates, in order, the questions a buyer’s investment committee will ask: is the customer base too local, too small, too shallow, too dependent on the founder’s old relationships, too concentrated? The idea is to answer the question before the buyer can raise it.

This is what three months of preparation buys.

The Financial Section’s Approach

The Financial Section in Chipmaker’s CIM did three things beyond presenting statements:

• They benchmarked. Income statement ratios, balance sheet ratios, and operating ratios were each set against industry-wide performance, so a buyer could see not only what the company earned but how that compared to peers. (On the methods buyers apply to those numbers, see How to Value a Business.)
• They isolated working capital. Net working capital got its own exhibit, because it becomes a negotiated term at closing and buyers price it.
• They connected past to future. The pro forma covered three forward years and moved from historical to projected by showing explicit drivers in units and dollars, rather than applying a growth rate to a base year. This matters more than any other single choice in the document — see the first pitfall below.

Length

For mid-market companies (those with sales between $10 and $100 million), our CIMs had been about 60 pages long. But over the last five years, we’ve used data and associated graphics wherever possible in place of words. On the other hand, we’ve published CIMs over 100 pages long for companies with multiple divisions or locations.

Avoid These CIM Pitfalls

1) Hockey Stick Projections

While presenting a positive outlook is important, unrealistic projections raise red flags about unrealistic seller value expectations, a major contributor to failed deals. Support financial projections and valuation with hard data. The IBBA and M&A Source Market Pulse survey, published quarterly, is a useful reality check on what lower middle market businesses actually sell for.

2) Closing Conditions

When describing seller’s closing condition preferences in a CIM, do not assume those wishes will be met. In fact, many CIM authors choose not to specify them at all. Deal structure, including earn-outs, is negotiated later and rarely resembles what either side first imagined. As Hollywood screenwriter William Goldman said, “Nobody knows anything” about the direction of future negotiations, at least until they begin.

3) Lack of Sufficient Detail

A vague CIM leaves potential buyers with more questions than answers. Spend the time to surface sufficient data describing all critical aspects of the business.

4) Ignoring Risks

Failing to disclose material risks weakens trust and credibility. Be transparent and explain, to the degree possible, how they can be managed or that their presence is not material. Buyers find these things in diligence regardless — see the most common mistakes M&A buyers make.

5) Inconsistent Information

Ensure consistency throughout. Conflicting information across CIM sections creates confusion, raises doubts, and implies sloppy due diligence.

6) Uninspiring, Incomplete Summary

As the first CIM section buyers see, the upfront overview should be crisp and compelling.

Last CIM Thoughts

Put yourself in the buyer’s shoes: you want to know everything relevant to the target’s past and future — its clients, markets, operations, assets and liabilities, value, and strategic fit. And no more.

Ultimately, the owners of a company for sale are responsible for what buyers see and learn. Many larger M&A advisors traditionally assign their most junior staff to CIM writing and financial analyses, leaving senior managers to rainmaking and deal negotiation. The wise seller confirms that experienced advisors are actively involved in your CIM’s composition and that the M&A advisor’s representatives you meet are the same ones buyers will meet. At Kuhn Capital, senior people write the CIM; see what we do and our transaction record.

In summary, a strong indicator of a seller’s quality is its CIM. Nothing dispels the impression of professionalism faster than misspellings, sloppy grammar, and wrong or missing critical data. These can even drive away otherwise strong buyers. Clean formats, on-point graphics, and clear writing set the stage for productive negotiations.
