What is a confidential information memorandum (CIM)?

Definition

Confidential information memorandum (CIM): A detailed marketing document describing a business for sale, given to potential buyers after they sign an NDA and used as the basis for their first bids.

How it works in a data room

The CIM, also called an information memorandum, is often the first document a bidder opens after the NDA is accepted. It usually covers the company’s history, products, customers, market, management team and financial track record, sometimes with projections. In a data room it sits at the top of the index, typically in view-only mode with a personalized watermark, because it is the one document every bidder reads closely and the easiest one to forward outside the process.

Why it matters in a deal

The CIM frames the price conversation. Bidders build their first valuations on its numbers, so anything it overstates tends to resurface later as a renegotiation once the full room opens. Sellers therefore keep it consistent with the underlying documents and update it if trading changes. Tracking who read which sections helps the adviser judge which parties are working seriously before first-round indications of interest arrive. The due diligence industry guide shows how the CIM connects to the material buyers verify later.

Example

An Australian engineering services firm prepares a 70-page CIM with its adviser. It is uploaded as a protected PDF that cannot be printed, and each bidder’s copy carries its company name and the viewer’s email across every page. When a partial copy appears on an industry forum, the watermark identifies the source within an hour and that party is removed from the process. See our Australia guide for local deal norms.
