From SBA financing and seller notes to earnouts tied to backlog conversion — here is how buyers and sellers structure deals in the lower middle market general contracting space.
Acquiring a general contracting business in the $1M–$5M revenue range requires deal structures that account for the industry's unique financial characteristics: project-based revenue cycles, backlog uncertainty, retainage balances, contingent liabilities from completed work, and heavy owner dependency. Unlike a subscription software business or a service firm with predictable monthly recurring revenue, a general contracting company's future earnings are directly tied to its backlog quality, bonding capacity, and the relationships of its owner. Buyers and lenders price this risk into how they structure consideration, and sellers must understand how their business's specific profile — license transferability, client concentration, and financial documentation — affects the deal terms they can expect. The most common structures in this industry combine SBA 7(a) debt, a seller note, and in some cases an earnout tied to post-close backlog conversion or revenue milestones. Asset purchases are preferred over stock acquisitions to limit exposure to legacy project liabilities. Working capital pegs and warranty holdbacks are standard negotiating points that reflect the realities of managing ongoing projects through a transition.

The most common structure for lower middle market general contracting acquisitions. The buyer finances 75–80% of the purchase price through an SBA 7(a) loan, injects 10–15% equity, and the seller carries a subordinated note for the remaining 5–10%. The SBA loan is typically structured over 10 years, with the seller note on a 2–5 year term that may include a standstill period during the SBA repayment window. Lenders often require the seller to remain engaged post-close to support license transfer, client introductions, and project continuity.
Pros
Cons
Best for: Entrepreneurial buyers with construction backgrounds acquiring an established general contracting firm with clean financials, a transferable license, and documented backlog of $1M or more.
Seller Financing with Earnout
In deals where SBA financing is unavailable or impractical — often due to thin EBITDA margins, undocumented financials, or a buyer without strong personal liquidity — the seller may finance a larger portion of the purchase price directly. An earnout component tied to backlog conversion, gross revenue, or EBITDA over 12–24 months post-close is common when future earnings are difficult to predict. This structure is also used to bridge valuation gaps when buyer and seller disagree on how much of the current backlog will convert to recognized revenue under new ownership.
Pros
Cons
Best for: Situations where the seller has strong client relationships that require a longer transition, financials need normalization, or the parties need to bridge a valuation gap around uncertain future backlog.
Asset Purchase with Working Capital Peg and Warranty Holdback
Regardless of how the purchase price is financed, the majority of general contracting acquisitions are structured as asset purchases rather than stock purchases. The buyer acquires specific assets — equipment, contracts, customer relationships, trade name, and goodwill — while the seller retains pre-close liabilities including completed project warranty claims, unresolved mechanic's liens, and any pending litigation. A working capital peg establishes a target level of net working capital (typically accounts receivable minus accounts payable, excluding retainage) to be delivered at close, and a holdback of 5–10% of the purchase price is escrowed for 12–18 months to cover warranty claims and retainage shortfalls on projects completed pre-close.
Pros
Cons
Best for: Any acquisition where the seller has completed projects still within warranty periods, open retainage balances, or any history of subcontractor or owner disputes on prior jobs.

General contracting businesses in the $1M–$5M revenue range typically trade at 2.5x to 4.5x EBITDA. Where a specific company lands in that range depends on backlog quality and diversification, owner dependency, license and bonding transferability, financial documentation quality, and whether the business has an experienced management team capable of operating without the seller. A company with signed contracts representing 9-plus months of forward revenue, a clean bonding history, and a project manager who can run operations independently will command multiples at the higher end. A single-owner shop with concentrated clients and informal bookkeeping will trade closer to 2.5x.
Yes. General contracting businesses are eligible for SBA 7(a) financing, and this is the most common debt structure for lower middle market acquisitions in this sector. The SBA lender will underwrite the business based on historical cash flow, backlog quality, and the buyer's industry experience. Key SBA-specific considerations for construction acquisitions include license transferability (the lender needs confidence the business can operate legally under new ownership), bonding capacity continuity, and whether the seller is willing to carry a subordinated note, which many SBA lenders require as evidence of seller confidence in the business.
In a general contracting business, the completed operations liability — meaning claims arising from projects finished before the sale — can be significant and difficult to quantify. Subcontractor disputes, mechanic's liens, warranty callbacks, and litigation from prior projects are common in the industry. An asset purchase allows the buyer to acquire only the specified assets (equipment, contracts, trade name, goodwill, and customer relationships) without inheriting the seller's corporate history and its associated liabilities. A stock purchase would expose the buyer to all pre-close obligations, including undisclosed claims. Note that asset purchases can complicate license transfers in some states, so legal counsel with construction industry M&A experience should review the structure before signing a letter of intent.
Retainage — typically 5–10% of contract value withheld by the project owner until substantial completion — is one of the most negotiated items in a general contracting deal. Buyers and sellers must agree on how outstanding retainage receivables are treated in the working capital peg, whether pre-close retainage that is collected post-close flows to the buyer or the seller, and how retainage on projects still in progress at the time of close is allocated. A common approach is to include a retainage schedule in the purchase agreement that specifies which retainage balances belong to each party based on the milestone that triggers collection, with a collection agent or holdback mechanism managing disputes.
An earnout is a contingent component of the purchase price paid to the seller after close based on the business achieving specified financial milestones. In general contracting, earnouts are most commonly tied to backlog conversion — that is, revenue recognized from contracts that were signed before the close date — or to gross revenue or EBITDA targets in the 12–24 months post-close. Earnouts make sense when buyer and seller disagree on valuation due to backlog uncertainty, when the seller's personal relationships are critical to retaining clients and projects, or when historical financials are inconsistent and the seller believes forward performance will justify a higher price. The risk is that earnout disputes in project-based businesses are common due to the subjectivity of revenue recognition timing, so precise definitions and measurement mechanics are essential.
This is one of the most critical deal-specific factors in a general contracting acquisition. In most states, a general contractor license is held either by an individual qualifier or by the business entity. If the license is held personally by the seller and the target state requires the new owner to obtain a new license or designate a new qualifier, there may be a gap period during which the company cannot legally pull permits or bid new work. This affects the deal timeline, the transition plan, and potentially the purchase price. Buyers should confirm license transferability with a construction attorney before signing an LOI, and sellers should proactively assess whether they have licensed employees who can serve as the qualifying party under new ownership.
