Quick answer: A sell-side M&A process moves through preparation, marketing, first-round bids, management meetings, a letter of intent, confirmatory due diligence, a purchase agreement and closing. Preparation sets the price more than any later stage, and the period after the letter of intent is where deals most often change. The owner’s job throughout is to keep the business performing, because a dip in results during the process gives the buyer a reason to renegotiate.
Key points
- A structured process creates competition among buyers, and competition is the owner’s strongest source of leverage.
- The business must keep performing while it is for sale. A weak quarter during diligence gives buyers a reason to ask for a lower price.
- The letter of intent is the turning point. It usually grants the buyer exclusivity, and from then on the owner has much less leverage.
- Surprises cost more than bad news. Disclosing problems early, with an explanation, protects both the price and the buyer’s trust.
The process in one view
A sale process is a managed sequence. Each stage has a purpose, a set of documents and a question the owner has to answer. The table summarizes the stages, and the sections below describe what happens in each.
| Stage | What happens | Main documents |
|---|---|---|
| Preparation | Set goals, estimate value, normalize financials, fix issues | Valuation, adjusted financials, add-back schedule |
| Marketing materials | Prepare a summary and a detailed presentation of the business | Teaser, confidentiality agreement, information memorandum |
| Outreach | Contact selected buyers, share materials under confidentiality | Buyer list, tracking log |
| First round | Buyers review materials and submit non-binding views of value | Indications of interest |
| Management meetings | Short-listed buyers meet the owner and team | Presentation, Q&A |
| Letter of intent | One buyer is selected on a proposed price and structure | Letter of intent, exclusivity |
| Confirmatory diligence | The buyer verifies financial, legal, tax and operating facts | Data room, quality of earnings report |
| Purchase agreement | The parties negotiate and sign the definitive contract | Purchase agreement, disclosure schedules |
| Closing | Conditions are met, funds move, ownership changes | Closing statement, ancillary agreements |
Preparation
Preparation determines more of the outcome than any later stage, because the facts that buyers will pay for are fixed before outreach begins. The work includes deciding what the owner wants from a sale (price, speed, certainty, a continuing role, a good home for employees), forming a view of value, and making the numbers credible.
Credible numbers mean financial statements that tie to tax returns, a monthly close, and a schedule of adjustments with support. The guide to preparing for a business valuation lists the records, and the add-back guide explains the adjustments. Problems found at this stage are cheap to fix or explain. Problems found by a buyer later are expensive.
Marketing materials and outreach
Two documents carry the early conversation. The teaser is a short, anonymous summary designed to gauge interest. The confidential information memorandum, covered in the comparison of valuation reports and CIMs, tells the full story of the business to buyers who have signed a confidentiality agreement.
An advisor then builds a list of buyers who could plausibly acquire the business: strategic buyers in the same or adjacent industries, financial buyers such as private equity firms and family offices, and sometimes individuals. The list is ranked by fit, ability to pay and likely interest, and buyers are approached in an order and manner that protects confidentiality. The difference between strategic and financial buyers shapes both the list and the pricing.
Bids and meetings
In the first round, buyers submit non-binding indications of interest, usually a range with the assumptions behind it. The advisor compares them on price, structure, financing, certainty and fit, and invites the strongest to meet management. Meetings are where buyers test whether the story in the materials matches the people behind it. They also test how much the business depends on the owner.
The letter of intent
The letter of intent turns a conversation into a proposal. It sets out the price, the form of payment, the treatment of debt and working capital, the role of the owner after closing, the diligence plan and the exclusivity period. Its most important feature is that it usually gives the chosen buyer an exclusive window to complete diligence, which means the competitive pressure ends when it is signed. Terms that matter should therefore be negotiated before signing and not after. The guide to reading a letter of intent covers each term.
Diligence
Confirmatory diligence is where the buyer checks what it was told. Accountants test the earnings in a quality of earnings review, attorneys examine contracts, litigation, intellectual property and corporate records, and operating teams look at customers, suppliers, systems and people. The quality of earnings guide explains the financial review, and the seller’s due diligence checklist lists the documents to expect.
Illustrative example: How diligence can change the price
A buyer signs a letter of intent at 6.0x adjusted EBITDA of $2,700,000, which is a price of $16,200,000. In diligence, its accountants reject $150,000 of add-backs that the owner proposed, lowering adjusted EBITDA to $2,550,000. At the same 6.0x, the price becomes $15,300,000, a reduction of $900,000. The numbers are invented to show the mechanics and are not benchmarks. The same pattern occurs when the working capital target is revised or debt-like items are added.
The purchase agreement and closing
The purchase agreement is the binding contract. It contains the final price and its adjustments, the seller’s statements about the business (representations and warranties), the rules for claims after closing (indemnification), any escrow or holdback, the non-compete, and the conditions to closing. It is negotiated in parallel with diligence, and its terms can matter as much as the price. Between signing and closing, the parties satisfy conditions such as third-party consents and any required filings. At closing, funds move and ownership changes hands, and a transition period follows.
What the owner controls
- Performance. Keep running the business as if it were not for sale. Buyers watch monthly results during diligence.
- Confidentiality. Decide who needs to know and when. Route buyer questions through one channel.
- Responsiveness. Slow answers to diligence requests give buyers a reason for concern and give the process time to lose momentum.
- Candor. Disclose known issues early with an explanation, because a surprise damages trust more than the issue itself.
- Team. Use an advisor, an attorney and a tax advisor who have done transactions of this kind. The comparison of advisors and brokers helps with choosing the first.
Owners on the other side of the table, who plan to buy a company instead of selling one, will find the matching steps in the buy-side process guide.
Frequently asked questions
How long does a sale process take?
It varies with the size and complexity of the business, the preparation done beforehand and how many buyers are involved. The preparation and marketing phases are within the seller’s control. Diligence and negotiation are not, and they are where timelines most often stretch. Owners should plan on months rather than weeks.
Will employees and customers find out?
A well-run process controls this. Buyers sign confidentiality agreements before receiving identifying information, early materials describe the business without naming it, and sensitive information such as customer lists is released late and to a smaller group. Owners should still decide in advance when and how key employees will be told.
What is the difference between an indication of interest and a letter of intent?
An indication of interest is an early, non-binding statement of the range a buyer might pay, given before it has seen much detail. A letter of intent is a more specific proposal after management meetings, setting out price, structure and timetable, and usually granting exclusivity to the buyer for a period.
Do I need a lawyer and an accountant as well as an advisor?
In nearly all cases, yes. The M&A advisor runs the process and negotiates the commercial terms. A transaction attorney drafts and negotiates the purchase agreement. A tax advisor structures the deal to manage taxes. A sale touches all three disciplines, and each protects a different part of the outcome.
Thinking about a sale or an acquisition?
The Impetus Group provides sell-side and buy-side M&A advisory, from preparation and buyer outreach to negotiation and closing. A transactional valuation is often the first step, scoped and priced separately.
