What Is an Information Memorandum and How to Write One
What Is an Information Memorandum?
An information memorandum — also known as a confidential information memorandum (CIM), investment memorandum, or selling memorandum — is the primary marketing document used in M&A transactions. It is a comprehensive, professionally written document that presents the business to potential buyers, providing the information they need to evaluate the opportunity and submit an indicative offer.
Think of the IM as the business's CV and covering letter combined. It tells the story of the business — where it came from, where it is today, and where it could go under new ownership. A well-written IM generates buyer excitement, builds confidence, and drives competitive bidding. A poorly written one kills deals before they start.
When Is the IM Used in the M&A Process?
The IM sits at a critical juncture in the sale process. After the teaser has generated initial interest and the buyer has signed an NDA, the IM is shared to provide the detailed information that will drive the buyer's decision on whether to submit an indicative offer. It is typically the most important document in the early stages of a transaction — more impactful than any meeting or presentation in determining which buyers progress and at what price.

Key Sections of an Information Memorandum
Executive Summary
The executive summary is the most important section — many buyers decide whether to read further based on this alone. It should concisely summarise the business, the investment thesis, key financials, and the opportunity. Aim for two to three pages that capture the essence of why this business is an attractive acquisition. Include headline revenue, EBITDA, growth rate, and the key reasons a buyer should be interested.
Business Overview
This section provides a detailed description of the company — its history, legal structure, products and services, competitive positioning, and operational model. Buyers want to understand what the business does, how it makes money, and what differentiates it from competitors. Use clear, factual language and avoid marketing hyperbole that will undermine credibility with sophisticated buyers.
Financial Performance
Present three to five years of historical financials in clear, consistent tables. Include revenue, gross profit, EBITDA, adjusted EBITDA (with documented adjustments), and net profit. Show trends and explain any anomalies. Include a revenue breakdown by customer, product, and geography. Present key ratios like gross margin, EBITDA margin, and revenue per employee. For guidance on presenting EBITDA, see /blog/what-is-ebitda-business-valuation.
Market and Industry Analysis
Demonstrate that the business operates in an attractive, growing market. Include market size, growth trends, competitive landscape, and the business's position within it. Buyers want to know the market has tailwinds and that the business is well-positioned to capture growth. Use third-party data and industry reports to support your claims rather than relying solely on management assertions.
Growth Opportunities
This is where you paint the picture of what the business could become under new ownership. Identify specific, credible growth opportunities — new markets, new products, operational improvements, acquisition targets, or underexploited capabilities. Be specific and realistic. Buyers discount vague claims of "huge potential" but respond positively to concrete, actionable growth plans with supporting evidence.
Management Team
Introduce the key people in the business — their backgrounds, roles, and tenure. Buyers want to assess whether the management team can continue to run the business successfully after the sale. Highlight the depth and capability of the team, and address the owner's role and transition plans honestly. For more on reducing owner dependency, see /blog/factors-that-affect-business-value.
Tips for Writing a Compelling IM
- Lead with your strengths — put the most compelling information early where it will be read
- Use data, not adjectives — "revenue grew 22% year-on-year" is more persuasive than "the business is growing rapidly"
- Be honest about weaknesses — sophisticated buyers will find them during due diligence, and undisclosed issues destroy trust
- Include professional visuals — charts, graphs, and clean formatting signal quality and attention to detail
- Write for the buyer's perspective — focus on what makes this an attractive investment, not what makes you proud of the business

Frequently Asked Questions
How long should an information memorandum be?
A typical IM for a UK SME ranges from 30 to 60 pages. It should be comprehensive enough to give buyers the information they need to submit an indicative offer, but concise enough that busy executives will actually read it. Quality matters more than quantity — well-structured, clearly written content with strong visuals is more effective than lengthy, dense text. TrueValue generates professional IMs that hit the right balance.
Who prepares the information memorandum?
The IM is typically prepared by the seller's M&A advisor in collaboration with the business owner and management team. The advisor brings experience in what buyers want to see and how to present information persuasively, whilst the owner provides the detailed business knowledge. TrueValue's document generation tools can produce a professional first draft from your deal and valuation data, significantly reducing preparation time.
What financial information should an IM include?
Include three to five years of historical financial statements (P&L, balance sheet, cash flow), adjusted EBITDA calculations with documented add-backs, revenue breakdowns by customer, product, and geography, key financial ratios and trends, and forward-looking projections with stated assumptions. Present financials in clear tables with supporting narrative. For more on EBITDA, see /blog/what-is-ebitda-business-valuation.
What is the difference between a teaser and an IM?
A teaser is a short, anonymous document (typically one to two pages) designed to generate initial buyer interest without revealing the company's identity. It highlights key financials and the investment thesis. The IM is the detailed document shared after the buyer signs an NDA — it identifies the company and provides comprehensive information across all aspects of the business. The teaser generates leads; the IM converts them into offers.
When should the IM be shared with buyers?
The IM is shared only after the potential buyer has signed a non-disclosure agreement (NDA). This protects the confidentiality of the detailed information contained in the document. Some advisors share the IM in stages — a summary version first, then the full document to shortlisted buyers. TrueValue's data rooms allow controlled distribution with activity tracking to monitor engagement.
