The Complete Guide to Selling a Lower-Middle-Market Company
Updated: Sep 29
Most owners sell a company once. There is no second attempt, no practice round, and almost no way to know in advance which decisions carried the most weight.
This guide covers the whole arc: how your company gets valued, what determines where you land in the range, how a real process runs month by month, what happens in diligence, and what to negotiate beyond price. It is written for owners of founder- and family-owned companies worth roughly one million to thirty million dollars, which is the segment the industry calls the lower middle market.
Part one: what your company is worth
The formula, and why both halves move
A lower-middle-market company is worth a multiple of its normalized earnings. Both halves of that sentence are moveable, and that is the entire opportunity.
Buyers do not value the bottom line on your tax return. They value the true economic earnings of the business, which requires normalization: adding back the owner's compensation, interest, taxes, depreciation, amortization, and documented one-time or personal expenses.
For owner-operated companies the measure is seller's discretionary earnings, or SDE. For companies where a management layer runs daily operations, buyers use adjusted EBITDA, which subtracts a market-rate salary for whoever will actually manage the company after closing.
That distinction is worth real money. A buyer purchasing an owner-operated company is buying a job. A buyer purchasing a management-run company is buying an asset. They pay very differently for the two, and EBITDA multiples run meaningfully higher than SDE multiples for the same business.
Where the multiple comes from
The multiple is not a mystery and it is not moved by conviction. It comes from closed transactions: actual sales of similar companies in similar size ranges. Listing prices are irrelevant, because they measure what optimistic sellers hoped for rather than what the market paid, and most of those companies never sold at all.
Size itself carries a premium. The same quality of business earns a higher multiple at three million dollars of EBITDA than at five hundred thousand of SDE, because more buyers can finance it and the earnings are considered more durable.
Add-backs decide more than owners expect
Every dollar of legitimate add-back is worth several dollars of purchase price, because the company sells for a multiple of earnings. That is why add-backs are simultaneously the most valuable and the most abused line items in a sale, and why buyers and lenders treat your add-back schedule as a credibility test.
Buyers accept owner compensation and benefits, clearly personal expenses, genuine one-time events, non-operating expenses, and documented non-recurring professional fees. They reject unnecessary-employee claims, recurring expenses labeled one-time, silent below-market related-party rent, unverifiable cash, and family members on payroll who cannot be explained.
Part two: what moves you inside the range
Every industry has a multiple range. Where you land inside it is determined by five things, and none of them are negotiating skill.
Earnings quality. Clean books, consistent margins, and add-backs you can prove with an invoice and a ledger line. Every add-back a lender's underwriter rejects reduces the earnings the loan is sized on, which reduces what a buyer can pay.
Customer concentration. One customer above twenty percent of revenue draws questions in every management meeting. Above thirty percent it starts changing deal structure through earnouts and holdbacks. It is the most common value suppressor in this market and among the most fixable, given time.
Owner dependence. If the customer relationships, pricing decisions, and technical knowledge live in your head, part of what the buyer is purchasing walks out the door at closing. They price accordingly, and lenders finance accordingly.
Recurring revenue. Contracted, repeating revenue trades at a premium to project or transactional revenue in every industry, without exception.
Growth trajectory. Buyers pay for the future, evidenced by the past. Three years of steady growth beats one exceptional year, because durability is what gets financed and what survives diligence.
All five are operational rather than financial, and all five are improvable given twelve to thirty-six months. That is the entire argument for starting early.
Part three: preparing to sell
The most valuable work in a business sale happens before anyone knows the business is for sale.
Five to three years out. Make the earnings defensible. Separate personal spending from the business or document it cleanly. Move related-party arrangements to market rates and paper them. Get a valuation, not to sell, but to learn which factors are holding the number down.
Three to two years out. Reduce dependence on yourself. Hire or promote someone who runs daily operations. Transfer customer relationships from you personally to a team. Document the processes that exist only in someone's head. The honest test: could the business run well for ninety days without you?
Two to one year out. Fix the structural risks. Diversify concentration. Convert major relationships to contracts with real terms. Address licensing held personally rather than by the entity.
Twelve months out. Assemble the file. Corporate records, contracts, leases, licenses, insurance history, equipment schedules, employee documentation. A data room that comes together in a week signals a well-run company; one that takes two months signals the opposite, and buyers price that signal.
For manufacturing, trades, and logistics companies, an equipment appraisal belongs in this stage. Book value reflects depreciation schedules rather than market reality, and the gap on well-maintained equipment is often significant.
Part four: how the sale process actually runs
Most lower-middle-market sale processes run six to ten months from launch to funding.
Weeks one to six: preparation and packaging. Financial normalization, add-back documentation, earnings benchmarked against closed transactions. The confidential information memorandum gets built. Anything a buyer's diligence would eventually surface gets found now, on your side of the table.
The memorandum matters more than owners expect. It is the document that decides whether qualified buyers engage, and the quality gap between a real CIM and a listing description is enormous.
Months two to five: confidential marketing. A blind teaser goes to a screened buyer list. Interested parties sign NDAs and get qualified for capital and intent before they learn your company's name. The objective is not finding a buyer. It is getting several qualified buyers to conviction on the same timeline, because competition is what moves price.
Months four to six: offers and the letter of intent. Offers arrive and get compared on more than price. One gets negotiated to a signed LOI with a defined exclusivity period.
Months five to nine: due diligence. Financial, legal, and operational review, plus the lender's parallel underwriting if the buyer is borrowing.
Months six to ten: documentation and close. Purchase agreement, disclosure schedules, consents, escrow, and funding.
Part five: diligence, offers, and terms
What happens in diligence
Deals die here, not because buyers find fraud, which is rare, but because they find surprises. Financial diligence reconciles your reported earnings to bank statements and tax returns and tests every add-back. Legal diligence reviews entity records, contracts and their assignability, leases, employment agreements, licenses, insurance, and litigation. Operational diligence assesses whether the business runs without you.
If the buyer is borrowing, the lender runs a parallel process that is frequently the true critical path.

Comparing offers
Two offers at the same headline price can put very different amounts in your account. Work through net proceeds after structure and tax, certainty of closing, the terms of any earnout, what happens to your people, and the representations and indemnification provisions that can move money after closing.
The best offer is the one with the highest risk-adjusted net proceeds that actually closes. That is rarely the biggest number on the page.

Terms that cost real money
Seller financing. Most deals at this size include a seller note, often structurally required on SBA transactions. It is a pricing tool rather than a concession, and it should always be papered with a promissory note, a security agreement, and a personal guarantee.
Working capital. A target gets set, usually on a historical average, and the price adjusts at closing against it. An inflated or seasonally unadjusted target can cost more than the entire advisory fee.
The LOI-to-purchase-agreement gap. The LOI is mostly non-binding on commercial terms and binding on exclusivity. Everything between signing it and closing tends to move in one direction.
Part six: your people, and choosing an advisor
What happens to your employees
For most founders this is the question underneath every other question. In an asset sale, employees are technically terminated by the seller and rehired by the buyer; in an equity sale, employment continues with the entity. In practice both usually look the same to the employee.
You cannot bind a buyer to keep everyone forever. You can negotiate retention agreements for key people, severance commitments for a defined period, benefit continuation, and honoring accrued time off.

Choosing the right kind of firm
Bulge-bracket banks work above roughly $250 million. Middle-market investment banks such as Houlihan Lokey and Harris Williams generally start around $50 to $75 million. Business brokers serve Main Street companies under roughly $1 to $2 million. Independent sell-side advisory firms exist for the range in between.
Inside whichever tier fits, five questions separate good firms from bad: do they work only one side of the table, where do their comparables come from, who actually runs your deal, how do they protect confidentiality, and are their incentives aligned with your outcome.
Why most listed businesses never sell
The majority of businesses put on the market never close. The causes repeat: an unrealistic price, financials that cannot survive scrutiny, a business that cannot run without its owner, financing that falls apart, a leaked process, a single buyer, and an owner who was not actually ready. Every one is a preparation problem rather than a marketing problem.
What companies are selling for, by sector
Choosing an advisor by sector
Advisor selection differs by industry, because the buyer pool and the specialist firms differ. These compare the firms that actually work each sector, with current multiples.
Selling by state
Licensing rules, buyer pools and industry mix differ by state. These guides cover what is specific to each market.

Where to start
If a sale is somewhere in the next five years, start with the number. Not to sell, but to learn what your company is worth today and which specific factors are holding that number down while there is still time to change them.
Aesir Business Advisors offers a complimentary valuation consultation: a conversation about your business, a preliminary value range built on your actual numbers rather than industry averages, and a straight assessment of what would move that number over the time you have. No cost, no obligation, entirely confidential.
Frequently asked questions
How long does it take to sell a lower-middle-market company?
Six to ten months from launch to funding for a properly run process. Preparation before launch adds twelve to thirty-six months if the goal is a full-value outcome rather than a fast one.
What is my company worth?
A multiple of normalized earnings, where the multiple comes from closed transactions in your industry and size range and is adjusted for earnings quality, customer concentration, owner dependence, recurring revenue, and growth.
Will my employees find out?
Not from a properly run process. Nothing published identifies the company, NDAs are executed before any identifying information is released, and disclosure is staged. Most owners tell a very small circle late and announce broadly only after the deal is signed and financed.
Do I have to carry a seller note?
Usually some portion, and often structurally on SBA-financed transactions. Sellers who refuse financing entirely frequently net less, because the buyer pool shrinks and the remaining cash buyers expect a discount for their certainty.
How are M&A advisory fees structured?
In the lower middle market, usually a success fee earned when the transaction funds, sometimes with a modest engagement fee credited against it at closing. Middle-market investment banks typically charge substantial non-refundable retainers in addition.
