How to Review an Information Memorandum When Buying a Business

Written by Paul Griffiths | Aug 24, 2026, 11:41:25 AM

An Information Memorandum, or IM, is one of the first detailed documents you are likely to receive when considering buying a business.

It should give you a structured overview of the company, including its financial performance, customers, management team, operations, market position and potential for future growth.

However, an IM is prepared as part of the sale process. It is designed to help you understand the opportunity, not to replace your own investigation.

The aim when reviewing an IM is therefore not simply to read what is presented.

You should use it to identify:

  • What makes the business attractive
  • Where the main risks may be
  • Which claims need further evidence
  • What questions you want to ask the seller
  • Whether the business fits your acquisition criteria
  • Whether it is worth progressing towards an offer and due diligence

The following checklist covers the main areas to assess when reviewing an Information Memorandum for a business you may want to buy.

 

1. Understand the Reason for Sale

One of the first questions to consider is why the owner is selling.

Common reasons include:

  • Retirement
  • Succession
  • Ill health
  • Relocation
  • Other business interests
  • Desire to reduce personal involvement
  • Need for additional capital or a larger owner to support growth

A genuine retirement sale can be very different from a business being sold because performance is deteriorating.

Consider whether the reason given makes sense when compared with the rest of the information in the IM.

For example, if the seller says they are retiring but the business has also experienced a sudden fall in revenue, you should understand what caused that decline.

The reason for sale is not automatically a red flag, but it should form part of your overall assessment.

 

2. Review the Owners and Directors

Understand who currently owns and manages the business.

Look for:

  • Ages and backgrounds of the shareholders
  • Percentage ownership
  • Day-to-day responsibilities
  • Length of time in the business
  • Whether any shareholders intend to retain equity
  • Whether the seller intends to remain involved after completion

One of the most important things to establish is how dependent the business is on the current owner.

If the owner personally manages all major customer relationships, sales activity, technical decisions and key employees, replacing them may be more difficult than the IM initially suggests.

 

3. Assess Customer Concentration

Customers are one of the most important areas to review.

Consider:

  • How many active customers the business has
  • What percentage of revenue comes from the largest customer
  • What percentage comes from the top five or ten customers
  • Whether customers are concentrated in one sector
  • Whether there is geographic concentration
  • How long customer relationships have existed
  • Whether revenue is contracted or repeat business
  • Whether relationships depend heavily on the seller

A business generating a significant percentage of turnover from one customer carries more concentration risk than one with a broad customer base.

Do not assume repeat customers automatically mean recurring revenue.

Try to establish what actually causes customers to return.

 

4. Understand Customer Contracts

If the company relies on long-term agreements, understand the nature of those contracts.

Questions to consider include:

  • How long do contracts last?
  • When are they due for renewal?
  • Can customers terminate early?
  • Are prices fixed or regularly reviewed?
  • Are there minimum purchase commitments?
  • Does a change of ownership affect the agreement?
  • Are contracts transferable?

A business may appear to have highly predictable revenue, but the underlying contractual arrangements may tell a more complicated story.

 

5. Review Supplier Dependency

Supplier concentration can create similar risks to customer concentration.

Assess:

  • Number of major suppliers
  • Percentage of spend with the largest suppliers
  • Availability of alternatives
  • Length of supplier relationships
  • Payment terms
  • Lead times
  • Exclusive arrangements
  • Overseas supply-chain exposure

If the company depends heavily on one specialist supplier, consider what would happen if that relationship ended or prices increased significantly.

 

6. Analyse Revenue Trends

Look beyond the latest turnover figure.

Review several years of performance where available and ask:

  • Is revenue growing, stable or declining?
  • Have there been unusually strong or weak years?
  • What caused major changes?
  • Is recent growth sustainable?
  • Has the mix of revenue changed?

Where there has been rapid growth, understand what drove it.

For example, was growth caused by:

  • New customers?
  • Price increases?
  • An acquisition?
  • One major contract?
  • Expansion into a new area?

The source of the growth matters just as much as the headline percentage.

 

7. Review EBITDA Carefully

EBITDA is commonly used when valuing businesses, so this section of the IM deserves particular attention.

Look at:

  • Reported EBITDA
  • Adjusted EBITDA
  • EBITDA margins
  • Historic trends
  • Recent trading
  • Forecast EBITDA

Do not assess EBITDA in isolation.

If revenue has grown significantly but EBITDA margins have fallen, understand why.

Likewise, if profitability suddenly improves shortly before the sale process, investigate what caused the change.

 

8. Challenge EBITDA Add-Backs

Adjusted EBITDA often includes add-backs for costs the seller believes will not continue after completion.

Some adjustments may be entirely reasonable.

Examples could include:

  • Genuine one-off legal costs
  • Personal expenses of the owner
  • Exceptional professional fees
  • Certain non-recurring costs

However, you should assess every adjustment critically.

Ask:

  • Is the cost genuinely non-recurring?
  • Has it appeared in previous years?
  • Will I need to replace the function after acquisition?
  • Has a realistic replacement cost been included?
  • Is the seller adding back an expense that the business will still require?

A £100,000 add-back can have a significant impact on valuation if the business is being valued using a multiple of EBITDA.

 

9. Examine the Balance Sheet

The balance sheet can reveal information that is not obvious from the profit and loss account.

Look at:

  • Cash
  • Borrowings
  • Stock
  • Trade debtors
  • Trade creditors
  • Fixed assets
  • Net assets
  • Working capital

Pay particular attention to unusually high figures.

For example:

  • Is stock high compared with revenue?
  • Are debtors taking a long time to pay?
  • Is there significant existing borrowing?
  • Is there a large cash balance?
  • Are there shareholder loans?

These issues may later affect the final transaction structure or purchase price.

 

10. Understand Working Capital

Working capital is particularly important because the business needs sufficient cash and short-term assets to continue trading after completion.

Look at:

  • Debtor days
  • Creditor days
  • Stock levels
  • Seasonal fluctuations
  • Historic working capital requirements

A profitable business can still experience cash pressure if customers pay slowly or large amounts of stock must be held.

Consider how much working capital you will need after buying the business.

 

11. Review the Asking Price or Valuation Expectations

Many Information Memorandums will not provide a fixed asking price.

However, there may be an indication of valuation expectations or the seller may provide guidance later in the process.

If a price is provided, consider how it compares with:

  • Maintainable EBITDA
  • Comparable businesses
  • Assets
  • Growth prospects
  • Business risk
  • Recent performance

Do not assume the seller's valuation is automatically the correct valuation.

Your eventual offer should reflect your own assessment of the business.

 

12. Assess the Management Team

A strong management team can significantly reduce acquisition risk.

Consider:

  • Who actually runs the company?
  • How long have senior managers been there?
  • What responsibilities do they have?
  • Which decisions require the owner?
  • Are there obvious management gaps?
  • Are key managers likely to stay after completion?

The less dependent the company is on the departing seller, the easier the transition may be.

 

13. Review the Employees

Look at the wider workforce as well as senior management.

Useful information includes:

  • Total number of employees
  • Departments
  • Length of service
  • Staff turnover
  • Key skills
  • Use of contractors
  • Vacancies
  • Reliance on particular individuals

Consider whether the company has enough capability to support future growth.

Also look for key roles that may currently be missing.

For example, a company may have grown successfully without a dedicated sales or marketing function, creating both a weakness and a potential growth opportunity.

 

14. Assess the Property

Understand what premises the business operates from.

Establish whether the property is:

  • Owned by the company
  • Owned personally by the shareholders
  • Held in a pension
  • Leased from a third party

If leased, review:

  • Rent
  • Remaining lease term
  • Break clauses
  • Upcoming rent reviews
  • Space requirements
  • Ability to expand

If property is owned separately by the seller, understand what arrangements will apply after the acquisition.

 

15. Review Capital Equipment

For asset-heavy businesses, understand the condition and future cost of machinery and equipment.

Consider:

  • Age
  • Condition
  • Ownership
  • Maintenance costs
  • Replacement cycle
  • Existing finance agreements
  • Required future investment

A business may generate strong EBITDA but require significant capital expenditure every year to maintain operations.

That affects the cash ultimately available to you as the buyer.

 

16. Assess Intellectual Property

Identify any important intellectual property owned or used by the company.

This might include:

  • Trade marks
  • Patents
  • Software
  • Copyright
  • Designs
  • Databases
  • Proprietary processes
  • Domain names

Consider whether:

  • The company actually owns the IP
  • It is properly registered where appropriate
  • Important IP belongs personally to the owner
  • Third-party licences are required
  • The IP can transfer with the business

Intellectual property can be a major source of value, particularly in technology, manufacturing and specialist service businesses.

 

17. Understand What Makes the Business Different

The IM should explain why customers choose the business rather than its competitors.

Possible differentiators include:

  • Specialist expertise
  • Strong reputation
  • Product quality
  • Customer service
  • Intellectual property
  • Location
  • Pricing
  • Distribution
  • Accreditations
  • Long-standing customer relationships

Be wary of broad claims such as:

  • "Market leader"
  • "Unique offering"
  • "No direct competitors"

unless there is evidence behind them.

 

18. Review the Market and Competition

Consider the wider environment in which the business operates.

Look at:

  • Market size
  • Growth rate
  • Major competitors
  • Barriers to entry
  • Regulation
  • Technology
  • Customer trends
  • Economic exposure

Try to separate objective market information from promotional language.

A strong business can still operate in a difficult market.

Equally, a growing market does not automatically mean the individual company will grow.

 

19. Challenge the Growth Opportunities

Most Information Memorandums will highlight opportunities for future growth.

These might include:

  • Geographic expansion
  • New products
  • New sectors
  • Cross-selling
  • Additional salespeople
  • Better digital marketing
  • E-commerce
  • International expansion
  • Acquisitions

Ask how realistic each opportunity actually is.

Consider:

  • Has the seller already tested it?
  • What investment would be required?
  • Why has the opportunity not already been pursued?
  • What evidence suggests demand exists?
  • How long would it take to deliver?

Most importantly, distinguish between growth already being delivered by the business and growth you would need to create yourself after acquisition.

You should be cautious about paying today's purchase price for value that only exists if you successfully deliver tomorrow's growth plan.

 

20. Review Sales and Marketing

Understand how the business currently generates new customers.

Look at:

  • Dedicated sales employees
  • Marketing spend
  • Website
  • SEO
  • Paid advertising
  • Social media
  • Referrals
  • Tendering
  • Distributor relationships
  • Repeat business
  • Owner-led sales

A company that relies almost entirely on the owner for sales may require significant changes after acquisition.

Conversely, weak marketing can sometimes represent a genuine opportunity if the underlying business is strong.

 

21. Examine E-commerce and Digital Sales

Where relevant, understand how much revenue comes through digital channels.

Consider:

  • Percentage of turnover generated online
  • Website performance
  • E-commerce platform
  • Customer acquisition channels
  • Conversion rates
  • Repeat purchases
  • Dependence on third-party platforms

Also consider whether there is realistic scope to increase digital revenue after the acquisition.

 

22. Review Financial and Management Information

Good management information can tell you a lot about how professionally the business is run.

Ask:

  • How often are management accounts produced?
  • Are they prepared internally?
  • How quickly after month-end are they available?
  • Does management regularly review performance?
  • Are budgets and forecasts prepared?
  • Are key KPIs tracked?

A business relying entirely on annual accounts prepared months after the year-end may give management less visibility over performance than one producing detailed monthly reports.

 

23. Understand Systems, Processes and Controls

Consider how dependent operations are on individuals rather than documented systems.

Look for processes covering:

  • Sales
  • Purchasing
  • Finance
  • Stock
  • HR
  • Customer service
  • Operations
  • Quality control
  • IT
  • Data security

Well-developed systems can make ownership transition easier.

Businesses where knowledge exists mainly inside the owner's head can carry greater transition risk.

 

24. Check the Location

The location needs to work commercially, but it may also need to work for you personally.

Consider:

  • Your commute
  • Whether you would relocate
  • Number of sites
  • Customer geography
  • Employee geography
  • Transport links
  • Future expansion

This is particularly important if you intend to become actively involved in running the company.

 

25. Consider How Long the Business Has Been Established

A long trading history can demonstrate resilience, but age alone does not make a business attractive.

Consider:

  • How has the company changed?
  • Has it adapted to its market?
  • Are customers long-standing?
  • Has management kept investing?
  • Is technology up to date?
  • Are products still relevant?

An established business with outdated systems can require significant investment.

 

What Information Might Be Missing From the IM?

An Information Memorandum is not supposed to contain everything.

Sensitive information is often held back until the buyer has progressed further.

However, missing information can help you identify the questions you need to ask next.

Pay particular attention if the IM provides little information about:

  • Customer concentration
  • Adjusted EBITDA
  • Recent monthly performance
  • Working capital
  • Owner dependency
  • Staff turnover
  • Major contracts
  • Supplier dependency
  • Capital expenditure
  • Debt
  • Forecast assumptions

A lack of detail does not necessarily mean there is a problem.

It does mean you should investigate further.

 

What Are the Main Red Flags in an Information Memorandum?

Potential warning signs can include:

  • Declining revenue
  • Falling margins
  • Aggressive EBITDA add-backs
  • Heavy customer concentration
  • Dependence on the owner
  • Weak management beneath the seller
  • Significant upcoming capital expenditure
  • High staff turnover
  • Major supplier dependency
  • Unrealistic growth forecasts
  • Poor-quality financial reporting
  • A vague explanation for the sale
  • Large unexplained changes in performance

A red flag does not automatically mean you should walk away.

It means the issue needs to be understood before you progress.

 

Remember: The IM Is Not Due Diligence

One of the most important principles when reviewing an Information Memorandum is that you are still at an early stage of the acquisition process.

The IM helps you understand the opportunity.

Due diligence helps you verify it.

Statements about:

  • Revenue
  • Profitability
  • Customers
  • Contracts
  • Assets
  • Employees
  • Intellectual property
  • Tax
  • Legal matters

will need to be supported by underlying evidence later.

Do not make a final investment decision based entirely on the IM.

 

What Should You Do After Reviewing the Information Memorandum?

Once you have reviewed the IM, prepare a structured list of questions.

Group them into areas such as:

  • Financials
  • Customers
  • Employees
  • Operations
  • Property
  • Growth
  • Transaction structure

Prioritise the points that could materially change whether you want to proceed.

The next stage will often be an introductory call or meeting with the seller and their advisers.

Use that meeting to understand:

  • The seller's objectives
  • How the business really operates
  • What is driving recent performance
  • Where the biggest opportunities are
  • What the seller expects from a buyer
  • What happens next in the sale process

 

Questions to Ask the Seller After Reading the IM

Useful questions may include:

  • Why have you decided to sell now?
  • How involved are you in daily operations?
  • Which customer relationships depend on you personally?
  • Why has EBITDA changed over the last three years?
  • What sits behind the adjusted EBITDA calculations?
  • Which customers are most important to the company?
  • Are any significant contracts coming up for renewal?
  • Who are the key members of the management team?
  • What major investment will the business require?
  • Which growth opportunity do you believe is most achievable?
  • Why has that opportunity not already been pursued?
  • What would you do differently if you owned the business for another five years?
  • What type of buyer are you looking for?
  • How long are you willing to remain involved after completion?

The answers can be just as valuable as the information contained in the IM itself.

 

Information Memorandum Review Checklist

Before deciding whether to progress a business acquisition, make sure you understand:

  • Reason for sale
  • Ownership structure
  • Owner dependency
  • Revenue trends
  • EBITDA
  • Adjusted EBITDA
  • Cash generation
  • Balance sheet
  • Working capital
  • Customer concentration
  • Customer contracts
  • Supplier dependency
  • Management team
  • Employees
  • Property
  • Capital equipment
  • Intellectual property
  • Market position
  • Competition
  • Sales and marketing
  • Growth opportunities
  • Systems and processes
  • Financial reporting
  • Future investment requirements
  • Indicative valuation
  • Proposed transaction structure

You will not necessarily have complete answers at this stage.

The objective is to understand the business well enough to decide whether it deserves further investigation.

 

From IM Review to Due Diligence

A good Information Memorandum should help move you from initial interest to a more informed view of the opportunity.

It should not convince you to buy the business on its own.

Your job as the buyer is to understand the commercial story, identify the assumptions behind it and decide what needs to be verified before committing further time and capital.

If the business still looks attractive after you have challenged the information presented, the next stages may include management meetings, valuation work, funding discussions, an indicative offer, Heads of Terms and ultimately due diligence.
