From SBA financing to seller earnouts, here is how buyers and sellers in the concrete and masonry industry close deals at the lower middle market level.
Acquiring a concrete or masonry contracting business requires a deal structure that accounts for the unique financial profile of project-based businesses — lumpy revenue, equipment-heavy balance sheets, key-man risk, and backlog uncertainty. Unlike a recurring-revenue software company, a concrete contractor's future cash flows depend heavily on the owner's relationships with general contractors, the condition of the equipment fleet, and the capability of the crew to run jobs independently. Most deals in this sector are structured as asset purchases using SBA 7(a) financing, with seller carry and transitional earnouts used to bridge valuation gaps and align incentives across the transition period. Buyers typically pay 2.5x–4.5x SDE, with businesses commanding the higher end when they have diversified commercial clients, experienced foremen, owned and maintained equipment, and documented backlog. Understanding each structural component — financing, seller carry, earnouts, and transition terms — is essential for both buyers and sellers to close a deal that works for everyone.

The most common deal structure for concrete and masonry acquisitions in the $1M–$5M revenue range. The buyer puts in 10–15% equity, the SBA 7(a) loan covers 80–90% of the purchase price, and the seller carries a subordinated note of 5–10% that is typically on standby during the SBA loan term. This structure allows buyers to acquire an established equipment fleet, backlog, and workforce without deploying large amounts of personal capital.
Pros
Cons
Best for: First-time acquirers, entrepreneurial searchers, and owner-operators purchasing a concrete or masonry business with at least $300K SDE and three years of documented financials.
Asset Purchase with Equipment Adjustment at Close
Virtually all concrete and masonry business acquisitions are structured as asset purchases rather than stock sales, allowing buyers to step up the tax basis of acquired assets — particularly the equipment fleet. The purchase agreement includes a detailed schedule of acquired assets, with receivables and payables adjusted at close. Equipment value is negotiated based on FMV appraisals, replacement cost assessments, and maintenance records.
Pros
Cons
Best for: Any acquisition of an established concrete or masonry contractor where the buyer wants clean separation from the seller entity's liabilities and the equipment fleet represents a significant portion of deal value.
Earnout Tied to Backlog Conversion
When a concrete or masonry business has a strong project pipeline but the buyer cannot verify whether verbal commitments will convert to signed contracts, an earnout bridges the valuation gap. The seller receives a base purchase price at close and earns additional consideration over 12–18 months based on the revenue and gross margin generated from the pre-close backlog or from retained client relationships.
Pros
Cons
Best for: Transactions where 20–35% of the stated business value is tied to a future backlog that has not yet converted to signed contracts, or where owner relationships with two or three key GCs represent the majority of revenue.
Full Seller Financing
In situations where SBA financing is unavailable — typically when financial records are informal, cash activity is high, or the business does not meet lender seasoning requirements — the seller may carry the entire note. This is less common in concrete and masonry but occurs in smaller transactions under $1.5M in purchase price where the seller is motivated to close quickly or the buyer cannot qualify for institutional financing.
Pros
Cons
Best for: Smaller concrete or masonry businesses under $1.5M in purchase price where SBA financing is not available due to financial record quality, or where the seller is highly motivated to complete a rapid transition to a known buyer such as a key employee or family member.

Concrete and masonry businesses in the lower middle market typically sell for 2.5x–4.5x Seller's Discretionary Earnings. Businesses at the lower end of that range often have high owner dependency, aging equipment, or concentrated customer bases. Businesses at the higher end typically have experienced foremen running jobs independently, diversified commercial and municipal clients, specialty capabilities like decorative concrete or post-tension slabs, and three or more years of clean financials. A $500,000 SDE business with strong fundamentals might command a $2M–$2.25M purchase price.
Yes. Concrete and masonry businesses are SBA-eligible, and the SBA 7(a) program is the most common financing vehicle for lower middle market acquisitions in this sector. Lenders will typically require three years of tax-prepared financial statements, a minimum SDE of $300,000–$500,000, and a business operating for at least three years. The equipment-heavy nature of concrete businesses can actually help SBA lenders feel more comfortable with collateral, provided the equipment is appraised and lien-free. Buyers should expect a 10–15% equity injection and should work with an SBA lender experienced in construction and trade contractor acquisitions.
An asset purchase allows the buyer to acquire the business's equipment, customer relationships, backlog, trade name, and workforce without inheriting the legal entity's historical liabilities — including prior lien claims, insurance disputes, bonding issues, or subcontractor litigation. This is especially important in concrete and masonry, where equipment liens, OSHA violations, and construction defect claims can surface years after a project is completed. Sellers often resist asset sales due to higher tax exposure, so buyers sometimes offer a modest price premium to compensate for the seller's incremental tax cost.
An earnout is a portion of the purchase price paid after close, contingent on the business hitting specific performance targets. In concrete and masonry deals, earnouts are most commonly tied to backlog conversion — whether the pre-close pipeline of projects actually executes and generates revenue and margin as represented. For example, if a seller claims $800,000 in active pipeline, the buyer might pay a base price assuming 60% conversion and structure an earnout for the remaining value if the pipeline actually executes. Earnouts typically run 12–18 months and represent 10–25% of total deal value. Clear metrics, a defined measurement period, and a neutral accounting methodology are essential to avoid post-close disputes.
Bonding capacity is one of the most overlooked transition risks in concrete and masonry acquisitions. Surety bonds are issued based on the financial strength and track record of the business owner, not the business entity alone. When ownership transfers, the surety relationship must be re-established under the new owner's name and financials. This process can take 30–90 days, during which the business may be unable to bid on public or bonded commercial projects. Buyers should begin the bonding capacity application process during due diligence — not after close — and sellers should facilitate introductions to their surety broker as part of the transition agreement.
Most lower middle market concrete and masonry acquisitions take 90–150 days from signed LOI to close when SBA financing is involved. The timeline includes SBA lender underwriting (45–60 days), equipment appraisal, environmental review, insurance and bonding transfer, and final purchase agreement negotiation. Deals with complex equipment schedules, revenue concentration issues, or financial record cleanup requirements can take longer. Sellers who prepare in advance — with clean financials, updated equipment lists, and current bonding documentation — significantly reduce due diligence timelines and improve the odds of closing on schedule.
