Investment memo
An investment memo (or investment memorandum) is an internal document prepared by an investor or investment team to summarize the thesis, diligence findings, risks, and recommendation for a specific investment opportunity. In venture capital and private equity, it is the primary artifact circulated to the investment committee before a vote. A strong memo covers the business model, market size, competitive landscape, team assessment, financial projections, entry valuation and terms, risk factors with mitigants, and a clear recommendation with supporting logic. It is distinct from a pitch deck (which is a seller's document) -- the investment memo is the buyer's critical analysis.
Problem & Application
A PE firm evaluating the acquisition of a 200-site RV park at $8,000,000 (10x EBITDA of $800,000) would structure the investment memo with: (1) thesis -- fragmented market, premium conversion opportunity; (2) market context -- outdoor hospitality tailwinds, same-store RevPAR growth; (3) financial analysis -- LBO model with debt structure, projected exit multiple at Year 5, IRR sensitivity at 8x vs. 12x exit EBITDA; (4) risk factors -- weather dependency, key-person concentration, capex needs for infrastructure upgrades; (5) recommendation -- approve at up to $8.2M with a 12-month post-close value-add plan. For family offices and independent sponsors underwriting campground or marina acquisitions, the investment memo discipline forces rigorous pre-close thinking that surfaces deal-breakers before, not after, the earnest money is non-refundable. Parikh Financial supports investment memo preparation through financial model builds, normalization adjustments, and management-fee-add-back recasting for seller-represented EBITDA.
In Short
Investment memos are key tools in the investment process, helping investors assess potential opportunities and risks, and ensuring informed decisions are made.
How it works
Mechanically, an investment memo works backward from a target return: you state the price and terms, project cash flows over a defined hold (often 3-7 years), and show the IRR and multiple-on-invested-capital (MOIC) the deal produces under base, downside, and upside cases. The discipline is forcing every assumption onto paper so the committee can attack it before capital is committed, not after. A common misunderstanding is that the memo's job is to sell the deal; in practice the strongest memos argue against themselves, dedicating real space to the bear case and pre-mortem so the decision survives scrutiny. Memos also serve a second life after close, becoming the baseline against which actual performance and underwriting accuracy are judged.
Worked example: memo for acquiring a boutique STR portfolio
An operator drafts an investment memo to buy a 12-unit short-term rental portfolio for $3,600,000. Trailing net operating income (NOI) is $360,000, a 10% cap rate. The memo lays out the capital stack: $2,160,000 in debt at 7.5% (60% LTV) and $1,440,000 of equity. Year-1 debt service runs roughly $162,000, leaving ~$198,000 in pre-tax cash flow, a 13.75% cash-on-cash return on equity. The base case assumes 4% annual revenue growth from dynamic pricing and a Year-5 exit at a 9% cap rate (NOI of ~$438,000 implies a $4,866,000 sale), producing an IRR near 18% and ~2.0x MOIC. The risk section flags seasonality, a possible local STR permit cap, and channel concentration on one booking platform, each with a mitigant. The recommendation: proceed, contingent on confirming permit transferability in diligence.
Frequently asked
What is the difference between an investment memo and a pitch deck?
A pitch deck is a seller's marketing document built to generate excitement and raise capital. An investment memo is the buyer's critical analysis, written for an investment committee. The deck argues why to invest; the memo stress-tests that argument, weighs the downside case, and ends with a defensible recommendation rather than a sales pitch.
What should be included in an investment memo?
Core sections are the investment thesis, market and competitive context, business and financial analysis with projections, the proposed price and deal terms, return metrics like IRR and MOIC, key risks paired with mitigants, diligence findings, and a clear recommendation. Strong memos also include a base, downside, and upside case so the committee sees the full range of outcomes.
Who writes an investment memo and who reads it?
It is typically written by the deal lead or investment team that sourced and diligenced the opportunity. The primary audience is the investment committee or partners who vote on whether to commit capital. Operators and family offices also use memos internally to evaluate acquisitions or major capital projects before approving the spend.
