How to Read a CIM Like a Buyer

A Confidential Information Memorandum, or CIM, is the document a seller uses to present their business to potential buyers. It is part marketing document and part financial summary, and learning to read one critically is one of the most valuable skills a first-time acquirer can develop. The goal is to see past the polish and understand what you would actually be buying.

Start with the earnings, not the story

Every CIM leads with a narrative about growth and opportunity. Skip ahead to the financials first. Look for normalized or adjusted earnings, often shown as SDE or adjusted EBITDA, and scrutinize the add-backs. Owner salary, one-time expenses, and personal costs are legitimate adjustments, but aggressive add-backs inflate the earnings a buyer pays a multiple on. If you cannot trace an add-back to a clear, recurring reality, treat it with caution.

Hunt for concentration and dependence

Two risks sink more small-business acquisitions than any others: customer concentration and owner dependence. If a single customer drives more than 20 percent of revenue, your downside is tied to one relationship you do not yet control. If the business runs on the seller’s personal relationships and daily involvement, you are buying a job, not an asset. The CIM rarely flags these directly, so look for them in the customer breakdown and the description of operations.

Use it to build your question list

A CIM is a starting point, not the truth. Its real value to a buyer is as a source of questions. Every claim, projection, and adjustment is something to verify in diligence. Read it once for the story, then read it again with a red pen, and bring the marked-up version to your first management meeting.
