Investment Memorandum vs Information Memorandum: The Terminology
In Australian M&A practice, the terms "Investment Memorandum" and "Information Memorandum" are frequently used interchangeably. Both refer to the comprehensive document prepared to present a business for sale — covering the business history, operations, financials, team, market, and transaction terms.
"Information Memorandum" is the more common term in the business brokerage market — particularly for small-to-mid market transactions. "Investment Memorandum" tends to be used more often in larger, more formal M&A processes or in private equity contexts where the frame is explicitly about return on investment.
The document structure is largely the same regardless of the label used. The primary audience is sophisticated buyers — corporate advisers, private equity, family offices, and strategic acquirers — who evaluate the business as an investment opportunity.
What an Investment Memorandum Includes (for Business Sales)
An Investment Memorandum prepared for a business sale covers the same core content as an Information Memorandum:
- Investment Thesis — the core case for why this business is an attractive acquisition, typically presented in the Executive Summary
- Business Overview — history, ownership structure, what is being acquired, and what is excluded from the sale
- Market Opportunity — total addressable market, growth trends, and the business's defensible position in the market
- Revenue Model & Financial Performance — historical P&L, revenue breakdown, EBITDA, and normalised earnings with add-backs explained
- Competitive Advantages — what gives the business its sustainable edge (brand, customer relationships, proprietary processes, licences, location)
- Team & Management — key personnel, experience, succession planning, and management depth
- Growth Opportunities — specific, quantified upside scenarios available to a new owner
- Risk Factors & Mitigants — honest assessment of key risks and how they are managed
- Transaction Structure & Returns — asking price, deal structure, and implied return metrics (revenue multiple, EBITDA multiple)
The Investment Memorandum in Private Equity & Capital Raising
In private equity and institutional investment, an Investment Memorandum (or Investment Committee Memo) is a document prepared internally by an investment team to present an acquisition or investment opportunity to the firm's investment committee for approval. This is distinct from the vendor-prepared Information Memorandum — it is written by the buyer, from the buyer's perspective, with the buyer's return expectations and risk analysis.
A private equity investment memorandum typically includes: an executive summary of the investment thesis, industry and market analysis, company overview and competitive positioning, financial model with returns analysis (IRR, MOIC), deal structure and valuation, due diligence findings, risk matrix, and the investment committee's recommendation.
This is a different document to what MemorandumMaker produces. MemorandumMaker produces the vendor-prepared IM — the document that presents the business to buyers. If you are a buyer or an investment team preparing an internal investment case, MemorandumMaker's document can serve as the source material for your internal Investment Memo.
Key Differences: Investment Memorandum vs Information Memorandum
While the two terms are largely interchangeable in the business brokerage context, there are some nuanced differences in how they tend to be used:
- Audience: An Information Memorandum is written for prospective buyers. An Investment Memorandum (in the PE sense) is written for an investment committee.
- Perspective: An IM is vendor-prepared and presents the business in its best professional light. An investment memo is buyer-prepared and critically evaluates the opportunity.
- Focus: An IM emphasises business history, operations, and all-round performance. An investment memo emphasises return metrics, IRR analysis, and exit strategy.
- Size: Both are typically 25–60 pages, but investment memos for large transactions can be significantly longer.
- Author: An IM is prepared by the broker or M&A adviser on behalf of the vendor. An investment memo is prepared by the buyer's deal team.
When Is an "Investment Memorandum" Label Appropriate?
Using the term "Investment Memorandum" rather than "Information Memorandum" is most appropriate when the transaction is framed explicitly as an investment acquisition — typically for larger businesses, private equity processes, or where the buyer is an institutional investor evaluating financial returns.
For most Australian business broker transactions in the $500K–$10M range, "Information Memorandum" or "Confidential Information Memorandum" is the standard and expected terminology. For transactions above $10M or where the buyer audience is primarily institutional, "Investment Memorandum" may be more appropriate.
MemorandumMaker produces comprehensive, professional documents that work effectively under either label. The content — financial depth, M&A writing style, Australian market conventions — is consistent with both.
