How to Sell a Construction Company

Construction is one of the hardest industries to sell well, and it has almost nothing to do with revenue. A contractor doing 40 million a year with fade on every job, a surety that will only bond the current owner, and three customers making up 70 percent of the backlog is a harder sale than a 9 million specialty contractor with a clean WIP schedule and a service department. This guide covers how buyers actually underwrite a construction business, the accounting that gets scrutinised first, and the structures that get these deals closed.

The WIP schedule is the first document a buyer reads

Almost every construction acquisition lives or dies on the work-in-progress schedule. Because contractors recognise revenue on percentage of completion, the WIP schedule is where earnings are made and unmade: it shows each open job, the original contract value, approved change orders, costs incurred to date, estimated cost to complete, and the resulting over or under billing. A buyer reads it to answer one question, which is whether the profit you reported was real or borrowed from jobs that have not finished yet. Underbillings are a receivable you have not invoiced. Overbillings are cash you have already collected and still owe work against. Both get scrutinised in a quality of earnings review, and both move the price.

• Margin fade: compare the gross margin you estimated at bid against what each closed job actually returned, over three years. Consistent fade tells a buyer your estimating is optimistic and every number in the forecast should be discounted.
• Change-order discipline: unapproved change orders sitting in WIP as revenue are the single most common adjustment in construction diligence.
• Job-level profitability, not company-level: buyers want the distribution, because an average built from two great jobs and six break-even ones is a different business.
• Retainage: how much is outstanding, how old it is, and whether any of it is disputed.

Backlog: what buyers pay for and what they do not

Owners routinely expect to be paid for backlog, and buyers routinely refuse. The reason is that signed backlog is work you have already been paid to perform at a margin that is already fixed, so it is not future earning power, it is an obligation with a margin attached. What buyers do pay for is the machine that keeps producing backlog: the estimating team, the general contractor and owner relationships, the prequalification status, the reputation that gets you invited to bid. Backlog matters as evidence that the machine works, and as a risk item if it is concentrated or priced below your historical margin. Expect a buyer to model backlog at your historical realised margin, not your bid margin.

Bonding capacity and the surety relationship

For any contractor doing bonded work, the surety is effectively a third party to the sale. Bonding capacity is underwritten on the balance sheet, the WIP, and the character and experience of the people running the business, which means it does not automatically transfer with the shares. A buyer who cannot maintain your aggregate and single-job limits is buying a smaller company than the one you are selling. The practical consequence is that the surety needs to be brought into the conversation early, usually under an NDA, and that a buyer with an existing surety relationship and a stronger balance sheet than yours is worth more to you than a higher bid from a buyer the surety will not support.

• Ask your surety what would happen to your aggregate limit under a change of control before you go to market.
• Indemnity agreements are personal. Understand what it takes to release your personal indemnity at closing, because it frequently outlives the sale.
• Buyers with balance-sheet strength can often raise your limits, which turns a constraint into a growth story and supports a higher price.

Licensing, the qualifying individual, and self-perform capacity

Contractor licensing is held at the state, provincial, or municipal level and usually depends on a qualifying individual who has passed the exam and carries the experience. If that person is you, the buyer needs a plan for the day you leave, and in some jurisdictions the licence does not survive a change of the qualifying party at all without a new application. Get clear early on which licences transfer with an entity sale, which need reapplication, and which trades you are qualified to self-perform. Self-perform capacity is a genuine value driver, because it protects margin, controls schedule, and is much harder for a competitor to replicate than a subcontractor list.

Customer and project concentration

Concentration is priced harder in construction than almost anywhere else, because the underlying relationship is often personal and the work is project-based rather than contractual. One general contractor, one developer, or one public agency making up a third of your revenue is a real risk that a buyer will address through structure rather than price alone. If you cannot diversify before you sell, expect part of the consideration to sit in an earnout tied to those relationships surviving, and expect the buyer to want you present long enough to hand them over. Read how buyers frame this in the entry on customer concentration.

Safety record, claims, and prequalification

Your experience modification rate and recordable incident rate are not soft metrics in a construction deal. They determine your insurance cost, they determine whether you can prequalify for larger work, and on many public and industrial projects they are a hard gate. A rising modifier is a direct hit to EBITDA and an indirect hit to the multiple, because it caps the work the buyer can pursue with the platform they just bought. The same is true of open litigation, lien claims, and warranty exposure on completed projects. None of these disqualify a business, but every one of them is better disclosed early than discovered in diligence.

Equipment, real estate, and working capital

Contractors carry heavy fixed assets and heavy working capital, and both get negotiated separately from the multiple. Assemble a current equipment register with age, hours, and maintenance history, and be honest about deferred replacement, because a buyer will build the capital expenditure back into the model. Real estate, including yards and shops, is usually separated: many sellers keep the property and lease it to the buyer at a market rate, which produces retirement income and lowers the price the buyer has to finance. Working capital is the item that surprises the most sellers. Retainage, underbillings, and slow receivables mean construction companies carry far more working capital than their revenue suggests, and the working capital peg negotiated at the letter of intent stage can move the cash you actually receive by more than a turn of EBITDA.

Who buys construction companies

The buyer pool splits four ways, and each one values a different thing. Regional strategics, usually a larger contractor in an adjacent geography or trade, pay for backlog access, prequalification, and self-perform capacity, and they are often the highest bidder when the fit is real. Private equity has built platforms in specialty trades, infrastructure services, and anything with recurring maintenance revenue, and pays EBITDA multiples for companies with a management layer already in place. ESOPs are unusually common in construction, because the workforce is stable and the tax treatment is favourable, though they rarely maximise headline price. Management buyouts preserve continuity but almost always need seller financing. If you want to see what buyers are actively looking for in your category, the construction buyer view shows how these companies get screened, and owners exploring quietly can start with a private buyer-fit check.

A realistic preparation timeline

Construction rewards preparation more than most industries because the fixes are slow. Monthly WIP reporting takes a quarter to implement and a year to become credible. Diversifying away from a dominant customer takes two bid cycles. Moving the licence off your name takes as long as the exam and the application. Building a project executive who can run operations without you is the longest of all. Owners who begin two to three years out consistently sell into the upper half of the range; owners who go to market in the middle of a bad job almost never do.

• Two years out: monthly WIP, job-level margin reporting, and a clean fixed-asset register.
• Eighteen months out: reduce customer concentration, formalise the estimating process, and name a second qualifying individual.
• Twelve months out: talk to your surety about change of control, resolve open claims, and clean up related-party leases.
• Six months out: assemble the data room, get an equipment and real-estate appraisal, and settle whether the property is in or out of the deal.
