What should you know before buying a construction company?

What are you buying in a construction company?

A construction company's value sits in five places:

• Backlog. Signed work not yet performed, and its margin.
• Relationships. General contractors, developers, public agencies and repeat owners who send work.
• Estimating and project management. The people who price jobs correctly and run them on budget.
• Bonding capacity and licenses. The permissions to bid and perform.
• Crews and equipment. The capacity to do the work.

The type of company changes the risk. A specialty subcontractor working for a few general contractors carries concentration risk. A general contractor carries more subcontractor and schedule risk. Public work brings bonding and prevailing-wage rules. Residential work depends on the housing cycle.

We do not quote an industry multiple. We have no reliable published figure, and construction results vary a great deal year to year. Price on verified cash flow across several years, adjusted for the backlog you are actually inheriting.

Will the company still be bondable after you buy it?

Many public projects and some private ones require performance and payment bonds. A surety issues them after underwriting the company's financial statements, work history and owners. Sureties usually require the owners to sign a personal indemnity.

When ownership changes, expect the surety to underwrite again. Two things can shrink bonding capacity after an acquisition:

• Acquisition debt and a smaller equity cushion weaken the balance sheet the surety looks at.
• The seller's personal indemnity and personal net worth leave with the seller.

Talk to the company's surety agent before you sign a letter of intent. Ask what program the company would have under your ownership and your capital structure. If bonded work is a large share of revenue and the answer is uncertain, the deal is uncertain.

What licensing should you check?

Many states and cities license contractors by trade and by project size, and many require a qualifying individual tied to the company. Rules vary by state. Check:

• Every license the company holds, the classification and limits, and whose name is on each.
• Whether a licensed employee will stay and serve as qualifier, and what the board needs to change the qualifier.
• Whether you can get licensed, and how long it takes.

If the seller is the only qualifier and plans to leave, solve that before closing. Our article on trade licenses and SBA loans covers the structures lenders see. Confirm with your lender and the licensing board.

Leases usually matter less here: a shop, a yard and equipment. Confirm the yard lease can be assigned and that leased equipment can be transferred or bought out.

How do you read the backlog?

Construction companies that use percentage-of-completion accounting produce a work-in-progress (WIP) schedule. It lists each open job's contract value, estimated cost, cost to date, billings to date and expected margin. It is the most important document in the deal.

• Overbilling means the company billed more than it has earned. The cash is in the bank, but the work still has to be paid for.
• Underbilling means it has earned more than it billed. It can signal a billing delay or a cost overrun the company has not admitted.
• Margin fade means estimated margins shrinking as jobs progress. Compare each job's estimated margin at bid, at midpoint and at close for the last two years.
• Retainage is money customers hold back until a job is complete. Confirm it is collectible.

Have a CPA who knows construction review the WIP schedule. Treat overbillings as a liability in the working capital peg. See what a working capital peg is.

Worked example: inheriting an overbilled job

Illustrative numbers for one open job:

1. Contract value: $2,000,000. Estimated total cost: $1,600,000.
2. Cost to date: $960,000, so the job is 60% complete. Earned revenue: $1,200,000.
3. Billed to date: $1,450,000. Overbilling: $1,450,000 minus $1,200,000 is $250,000.
4. Remaining cost to finish: $640,000. Remaining billings: $550,000.
5. After closing, you spend $640,000 and collect $550,000. That is $90,000 of cash out of your pocket, before retainage timing.

If the seller takes the company's cash at closing and the working capital peg ignores the overbilling, you pay for work the seller already billed. Multiply that across every open job.

What kills construction deals?

• The surety will not support the company under new ownership.
• The owner is the estimator and the relationship, and nobody else can win work. Test it with whether the business can run without its owner.
• Loss jobs hidden in the WIP schedule.
• Concentration in one or two general contractors or developers.
• Coverage. Lenders measure 1.25x on the last fiscal year or the average of the last two, not on projections. A strong year followed by a weak one can fail.

Where these numbers come from: The 1.25x coverage test and its measurement period are SBA SOP 50 10 8.1 rules, summarized by Beancount. The worked example uses illustrative numbers. We do not cite a construction-company multiple because there is none in our sourced data. SOP 50 10 8.1 applies to loans that receive an SBA loan number on or after October 1, 2026 (SBA Information Notice 5000-880695).

Related questions

Do I need construction experience to buy a construction company?

You need either the experience or people who have it and will stay. Estimating, project management and safety are where companies lose money. See whether you need industry experience.

Will an SBA lender finance a construction company?

Lenders do finance them, subject to the same rules as any acquisition: 10% minimum injection on an Initial Acquisition, 1.25x coverage on historical cash flow and an independent valuation. Lumpy results and large working capital needs make underwriting harder. Ask lenders early whether they lend in the trade.

Should the seller stay after closing?

Usually yes, to hand over relationships and bonding history. Under SBA rules the seller may stay as a consultant or employee for up to 24 months in aggregate after closing.
