CIM (Confidential Information Memorandum)

A Confidential Information Memorandum (CIM) is the primary marketing document used in a structured business sale process. Prepared by the seller's M&A advisor or business broker, it provides prospective buyers with a comprehensive overview of the business — its history, products or services, financial performance, competitive position, management team, and growth opportunities — in enough detail for a buyer to form a preliminary valuation view and decide whether to submit an offer.

The CIM is distributed only after a prospective buyer has signed a non-disclosure agreement (NDA). It is not a legally binding document and will include disclaimers stating that all information is subject to verification through due diligence and that the seller reserves the right to reject any offer for any reason. A well-prepared CIM presents the business in a favourable light while remaining accurate enough that no material discrepancies emerge when buyers conduct their own investigation — misrepresentations discovered during due diligence routinely derail transactions or result in price adjustments.

Common sections of a CIM include: an executive summary, company overview and history, products or service descriptions, financial summary (typically three to five years of historical financials with EBITDA normalization adjustments shown), market and competitive context, management and employee overview, and transaction process details including the timeline and bid instructions. For buyers, the CIM is typically the document that prompts submission of an indicative non-binding offer or letter of intent. The quality and completeness of a CIM is often an early signal of how organized and well-advised the seller is.
