The email arrives on a Tuesday, the third one this quarter. “We represent a well-capitalized group actively acquiring companies in your industry. Would you be open to a brief, confidential conversation?” If you own a company doing $30 million in revenue, you have a folder of these, read once and ignored, from private equity associates, search funds, and competitors you half recognize. Most owners file them as flattery or spam. They are neither. They are field reports from a real market, one in which your company already trades whether you participate or not, and one whose rules almost nobody explains to the people who own the merchandise.
One fact shapes everything else in this guide: you will probably sell one company in your life. The people sending those emails buy companies for a living, some of them several a year, each on their tenth or fortieth transaction, running playbooks refined at your predecessors’ expense. That imbalance, more than any spreadsheet, is what this book exists to correct. Correcting it starts with understanding what this market actually is and why it works the way it does.
The Size Bands: Where Your Company Trades
Private companies do not trade in one market. They trade in tiers, and the tier your company occupies determines nearly everything about how it will change hands: who shows up, what they pay with, which earnings number they price, how long the sale takes, and how much of a market can be assembled around you.
The tiers are conventionally drawn by enterprise value, a term Chapter 5 defines precisely. The working idea is enough for now: enterprise value is the value of the entire business, debt and equity together, before the proceeds get divided. A house is worth what it is worth whether or not it carries a mortgage. The mortgage decides what the seller pockets at closing, not what the buyer pays for the property. Enterprise value is the price of the house. When this guide says “a $40 million company,” it means $40 million of enterprise value unless it says otherwise.
Definitions of the bands vary by source, and arguing over the borders is a parlor game for advisors. Some firms draw them by revenue, some by EBITDA, some by the size of check their fund writes. What matters is using one definition consistently, so here is FIH’s, used throughout this guide: the lower-middle market runs from roughly $5 million to $100 million of enterprise value. In practice, that usually corresponds to $5 million to $150 million of revenue and $1 million to $15 million of EBITDA. Below it sits Main Street, businesses under $5 million of enterprise value. Above it sit the core middle market (roughly $100M-$500M), the upper middle market (roughly $500M-$1B), and the large-cap world above $1 billion, where companies are public or about to be. The chart below lays out the bands.
The tiers at a glance, using FIH’s working definitions; conventions vary by source.
| Segment | Enterprise value | Typical company profile | Who typically acquires |
|---|---|---|---|
| Main Street | Under $5M | Owner-operated; under $1M in earnings | Individuals, often with SBA-backed financing |
| Lower-middle market | $5M-$100M | $5M-$150M revenue; $1M-$15M EBITDA | Private equity, strategics, family offices, search funds, individuals at the low end |
| Core middle market | $100M-$500M | Professional management; institutional-grade reporting | Private equity, public strategics |
| Upper middle market | $500M-$1B | Regional or national platforms | Large sponsors, public acquirers |
| Large-cap | Above $1B | Public, or ready to be | Public companies, the largest funds |
To see why the bands matter, follow three companies to market in the same year. A plumbing business with $4 million of enterprise value sells through a business broker, off a listing, priced on seller’s discretionary earnings, to an individual using a government-guaranteed loan and a seller note; the experience resembles selling commercial real estate. A specialty manufacturer at $40 million of enterprise value sells through an M&A advisor in a managed competitive process, priced on adjusted EBITDA, to a private equity firm using institutional debt and fund equity, complete with a quality of earnings review and a 60-page purchase agreement. A $400 million distributor sells through an investment bank in a formal auction, with public strategics and large sponsors bidding, financing packages arranged in advance, and diligence teams numbering in the dozens. Same country, same economy, three different games with three different rulebooks.
The lower-middle market is the strangest of the three, because it is the band where professional capital and first-time participants meet. A Main Street owner usually sells to a counterparty about as inexperienced as she is. A $400 million company has a CFO, a board, and bankers on retainer. The owner of a $40 million company typically has neither form of protection: the company is large enough to attract the most sophisticated acquirers in the market and small enough that nobody inside it has ever sold one.
Five Ways This Market Plays by Different Rules
Owners often assume the lower-middle market is a scaled-down version of the dealmaking they read about in the business press. It is not. Five structural features make it a different arena, and each one has money attached.
Price does not exist until you build a market
A share of a public company reprices every second the exchange is open. Your company has no price. It has a range of defensible opinions, and the range is wide: the same business can support honest valuations that differ by millions, because its value depends on who is asked and what they would do with it. Two consequences follow. First, any private-company valuation is a range, not a point, and an advisor who hands you a single confident number is marketing, not analyzing. Second, the price you ultimately achieve depends heavily on the market you assemble around the asset. Illiquid assets are priced by the quality of their price discovery, and in a private sale, price discovery is something you manufacture. Chapter 10 walks through how a well-run process does exactly that.
Information runs lopsided in both directions
You know the company; the acquirer knows the market. You know which customer relationship is wobbling, which manager actually runs operations, and where the deferred maintenance hides. The acquirer knows what comparable companies have actually traded for, which contract terms are standard and which are aggressive, and how much risk can be pushed into a deal’s structure before an inexperienced counterparty notices. Due diligence exists to close the acquirer’s information gap, and it is systematic, professional, and typically runs for months. Nothing in the standard process closes the owner’s gap. It gets closed only by preparation: reading before you need to, and hiring people who see the market every week. The asymmetry rarely announces itself as a lowball offer. It shows up quietly, in terms you have never seen before and the other side has negotiated a hundred times.
Companies here are sold once and bought constantly
In most lower-middle-market transactions, the acquirer has closed more deals than everyone on the owner’s side of the table combined, unless the owner hires advisors who transact for a living. This is the market’s thinnest layer of protection: many companies at this size go to market with no representation at all, or with a generalist attorney and the family accountant facing a team that does nothing but buy companies. To be clear, repeat acquirers are not villains. They are professionals doing their jobs, and most are straightforward to deal with. The problem is not their skill; it is your one-shot exposure to it. A negotiation between someone playing their only hand and someone playing their fiftieth tends to price accordingly.
Key point. Most lower-middle-market companies are sold once, by an owner who has never sold a company, to an acquirer who buys them for a living. Nearly every rule, custom, and pricing convention in this market flows from that asymmetry, and nearly every dollar of avoidable loss traces back to it. The corrective is to understand the game before you are in it.
The lender is the third party at every table
Most acquisitions in this band are paid for partly with borrowed money, which makes the lender an invisible counterparty in your sale. The price an acquirer can offer is constrained by what a lender will advance against your company’s cash flows, so your deal is being underwritten twice: once by the acquirer, once by their bank or credit fund. Credit conditions therefore move private-company prices whether or not your performance changes; when debt gets expensive or scarce, offers soften across the board. And your company’s financeability is itself a pricing variable: clean financial statements, steady cash flows, and a diversified customer base widen the pool of acquirers who can fund a purchase. A company that lenders decline can only be bought by cash buyers, and cash buyers price like they know it.
The owner is a load-bearing wall
At $30 million in revenue, the owner is frequently the top salesperson, the holder of the key relationships and licenses, the chief culture officer, and the tiebreaker on every hard decision. An acquirer is not buying the business as it runs today; they are buying it as it will run without you, or with you on your way out. The gap between those two versions of the company is measured and priced, either as a lower offer or as consideration made contingent on a future you no longer control. A useful self-test: what happens to revenue, and to your five most important customer relationships, if you disappear for eight weeks? Public companies are built to survive the departure of any single person. Lower-middle-market companies usually are not, and acquirers underwrite that difference every time.
The Valuation Gap: Why Private Companies Trade Below Their Public Peers
A multiple is just the price of a dollar of earnings. Public investors routinely pay far more per dollar of earnings than acquirers pay for smaller private companies in the same industry, and owners tend to discover this at the worst possible moment: after anchoring on a public comparable or a headline from a megadeal.
The gap has causes, and every one of them is rational. Small companies are fragile in ways large ones are not: one customer defection, one key departure, or one lost contract can move the entire earnings stream, so the stream deserves a lower price per dollar. Key-person risk and thin management depth mean the asset’s performance depends on people who may leave with the seller. Customer concentration that would be immaterial at public scale is common at this scale and gets priced hard. Information quality differs: audited, regulated, continuously disclosed financials on one side; internally prepared statements of varying rigor on the other. And liquidity itself is worth money. A public shareholder converts to cash in seconds at a posted price; an owner converts in months, at a negotiated price, net of meaningful transaction costs. Investors pay a premium for the exit door, in every asset class.
Finance calls this the size premium when viewed from the investor’s chair: smaller, riskier, less liquid assets must offer higher expected returns to attract capital. From the owner’s chair, the same arithmetic is a size discount, because a higher required return is mechanically a lower price per dollar of earnings. Chapter 8 puts typical ranges on all of this. For now, what matters is that the discount is real, rational, and only partly fixed.
Illustrative example. A public facilities-services company earning $300 million of EBITDA might trade at 12.0x EBITDA in the stock market, an enterprise value of $3.6 billion. A private commercial HVAC contractor in the same broad sector, earning $3 million of EBITDA with similar margins, might clear 5.5x in a well-run sale, roughly $16.5 million. Same industry, same economic engine, less than half the price per dollar of earnings. The difference is not a market error. The contractor has one owner-operator instead of a management bench, a handful of large accounts instead of thousands, unaudited statements, and no button an investor can press to sell in seconds. These numbers are hypothetical; the reasoning is not.
Take two things from the gap. First, arguing with the discount is wasted effort; the productive move is working on the parts you control, because within the lower-middle market the spread between a well-prepared company and an unprepared one with identical earnings is wide, and later chapters are largely about capturing it. Second, the gap explains the emails from the start of this chapter. Your earnings are cheaper per dollar than almost any comparable asset professional capital can buy at scale, and professional capital has noticed.
The Cast: A Preview of the Players
Owners in this market are mostly founders and families, usually holding the majority of their net worth in the company, usually selling for the first and only time. Their motivations, and how those motivations shape deals, get a full treatment later in Part I.
Acquirers come in distinct species: strategic companies buying competitors and adjacencies, private equity firms buying platforms and add-ons, family offices, search funds, independent sponsors, and individuals at the smaller end. Each type pays on different logic, moves at a different speed, and offers a different life to the owner after closing. Chapter 3 profiles each in depth; for now, know that “the buyer” is not one animal.
Intermediaries scale with the bands: business brokers serve Main Street on a listing model, while M&A advisors and boutique investment banks serve the lower-middle market by building buyer lists, running competitive processes, and defending value through diligence. Chapter 18 covers how to choose one, and, honestly, when you might not need one.
Lenders are the fourth member of the cast and the least visible: banks, SBA-backed lenders at the smaller end, and private credit funds, all underwriting the same cash flows the acquirer is buying and holding an effective veto over price.
Attorneys matter more than most owners expect, because the purchase agreement is a risk-allocation machine, not paperwork. The M&A specialist and the generalist who handled your leases are different professions. Accountants play two positions: tax structuring, which rewards attention long before a deal, and earnings verification during one, where your historical CPA and a transaction accountant do very different jobs.
What a Deal Actually Is
Strip away the vocabulary, and every transaction in this book is the same trade. The acquirer buys a stream of future cash flows and accepts the risk that the stream disappoints. The owner gives up that risky stream in exchange for certainty, mostly cash, today. That is the whole deal. Everything else is implementation.
Hold that frame and the rest of this guide organizes itself. Valuation, all of Part II, is pricing the stream: which earnings measure describes it and what a dollar of it is worth. Due diligence is verifying the evidence for the stream. Deal structure is deciding who holds which risks if the future misbehaves, which is why two offers with the same headline number can be millions apart in real value. Negotiation is dividing the surplus between the side that wants certainty and the side that is paid to take risk.
The frame carries two working implications. For owners: the market does not pay for your past. The years, the sacrifices, and the capital you put in are not priced; they matter only as evidence about the future. Anything that makes your future cash flows more believable adds to your price, and anything that makes them less believable subtracts from it, often quietly, through structure rather than the headline. For acquirers: you are not buying what the company did, you are buying what it will do without its current owner, funded with money that must be repaid from the very stream you are underwriting, which makes optimism a cost you pay at closing.
Keep the frame in view. Every chapter that follows, from add-backs to earnouts to the final wire transfer, is a variation on it.
The Bottom Line
- This guide’s canonical definition of the lower-middle market, used throughout: $5 million to $100 million of enterprise value, roughly $5M-$150M of revenue and $1M-$15M of EBITDA; definitions vary by source, but ours holds from here on.
- The size band your company trades in determines the buyers, the financing, the earnings measure, and the process, so know your band before you price anything.
- Lower-middle-market companies are typically sold once, by owners who will never do it again, to acquirers who do it constantly; preparation and representation exist to offset that asymmetry.
- Private companies price below their public peers for rational reasons (fragility, key-person risk, concentration, information quality, illiquidity), and part of that discount is structural while part is within an owner’s control.
- A deal is a transfer of future cash flows plus the risk that they disappoint; valuation, diligence, structure, and negotiation are all downstream of that single frame.
