A Confidential Information Memorandum (CIM) plays a pivotal role in any M&A transaction. It’s the cornerstone document that introduces the company, sets the tone for buyer discussions, and frames the valuation narrative. But even top investment banks make recurring CIM mistakes that can slow deals or erode buyer confidence.
This guide outlines 10 common CIM mistakes seen in investment banking deal materials, plus how to fix each one.
A strong CIM goes beyond summarizing a company. It tells a credible, evidence-based story that motivates buyers.
Poorly constructed CIMs often lead to:
Slower deal velocity
Endless buyer Q&A cycles
Reduced trust and valuations
Fixing these issues starts with recognizing the most frequent pitfalls in M&A deal documentation—and knowing how to correct them.

Many of the most critical sections of a CIM are based on recycled positioning and standardized boilerplate text.
How to fix: Investment analysts and associates should make each CIM more concise, data-driven, defensible, and targeted at the prospective buyer.
The Market Overview section of a CIM typically shows graphs of market price or company value without explaining any rises or falls.
How to fix: A good CIM will anticipate and answer obvious questions from buyers about why each peak or trough happened.
Most CIMs make generic claims that the company being sold is an innovator and a market leader without proving it through external validation.
How to fix: Each positive claim should be explicitly backed up by third-party recognition such as media coverage, or analyst praise.
Data used in CIMs is often drawn from a wide range of sources with limited reliability and uncertain provenance. Yet buyers need to have confidence that every claim or statement in a CIM is accurately sourced, or they may pull out of the deal after doing their own due diligence.
How to fix: Data should come from approved, premium content with clear and reliable sourcing.
The narrative in a CIM is usually driven by the seller and their investment bank, not mapped to strategic buyer intent.
How to fix: The best CIMs reflect an understanding of prospective buyers’ portfolio moves, stated strategies, and public statements. This in turn increases deal velocity because buyers will move to a decision more quickly, without a lengthy back-and-forth of questions and answers.
As CIMs are focused on selling a company, that firm’s risks and issues tend not to be a major focus. But this approach is shortsighted because a buyer will carry out their own due diligence, which can lead to a deal collapsing at the last minute if they find something problematic.
How to fix: A CIM which proactively flags all issues from the start will build trust with buyers.
Where companies are described in a CIM, the name of the holding company is typically presented without any insight into their ultimate beneficial ownership or risk exposure.
How to fix: Analysts can correct this mistake by drawing on data on PEPs and sanctions, and company data which includes complex ownership structures.
The Competitive Landscape section of a CIM typically namechecks the seller’s competitors in a generic listing of entities with minimal insight into their latest moves or how they affect the deal environment.
How to fix: Enhanced CIMs will help buyers to understand the market by visualizing deal activity among peer firms.
CIMs make claims about the seller’s future growth strategy, but these are usually presented without independent verification or proper explanation for the forecasts.
How to fix: Analysts should go a step further to provide external confirmation of growth indicators, and justification for any projections.
Analysts often juggle multiple sources—some free, some paywalled—to verify data, consuming hours of valuable time.
How to fix: Save time, and increase accuracy, by using a content provider which offers a wide range of reliable and relevant data sources through a single access point.
