How to Structure the Acquisition of a Concrete or Masonry Business

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.

SBA 7(a) Loan with Seller Note

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.

Buyer equity 10–15% | SBA 7(a) loan 80–85% | Seller note 5–10%

Pros

  • Maximizes buyer leverage with as little as 10% equity down, preserving working capital for operations and equipment maintenance post-close
  • Seller carry signals the seller's confidence in the business and satisfies SBA lender requirements for deal structure alignment
  • Allows buyers to acquire businesses at $1M–$3M purchase price without institutional backing or private equity capital

Cons

  • SBA lenders scrutinize project-based revenue and may require seasoned backlog documentation and clean three-year tax returns before approval
  • Seller note is typically on standby for 24 months, meaning sellers do not receive full proceeds at close
  • Personal guarantee requirements and SBA collateral rules can complicate asset valuations when equipment is central to business value

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.

Asset purchase used in approximately 90% of lower middle market concrete and masonry transactions

Pros

  • Buyer avoids inheriting unknown liabilities, prior liens on equipment, or legacy bonding claims from the seller entity
  • Step-up in depreciation basis on equipment reduces taxable income in early years of ownership, improving post-acquisition cash flow
  • Equipment schedule allows granular negotiation — buyers can exclude aged or high-maintenance assets and reduce purchase price accordingly

Cons

  • Asset purchase creates complexity in transferring GC relationships, subcontractor agreements, and bonding capacity, which must be re-established under the new entity
  • Sellers face higher tax exposure on asset sales versus stock sales, which can create friction in price negotiations
  • Accounts receivable carve-outs and work-in-progress adjustments at close require careful job-cost accounting to avoid disputes

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.

Earnout typically represents 10–25% of total deal value, paid over 12–18 months post-close

Pros

  • Aligns seller's incentive to actively support the transition, including introductions to GC contacts, developers, and municipal clients
  • Reduces buyer risk when the business relies heavily on one or two large GC relationships that have not yet been formalized
  • Allows sellers to capture full valuation upside if the backlog converts as represented, rather than accepting a discounted price at close

Cons

  • Earnout disputes are common when revenue attribution is unclear — particularly when new buyers win projects that overlap with seller-era relationships
  • Sellers lose control of operations post-close, meaning earnout performance depends partly on the buyer's execution and bidding strategy
  • Complex to structure in project-based businesses where revenue recognition varies by project milestone and percentage of completion

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.

Seller carries 100% of purchase price with 10–20% down payment at close

Pros

  • Fastest path to close with no bank underwriting timeline, SBA approval process, or third-party lender requirements
  • Seller retains interest income over the loan term, which can improve total proceeds compared to a discounted all-cash sale
  • Flexible terms can be customized to match the seasonal cash flow patterns of a concrete or masonry contractor

Cons

  • Seller carries full credit risk — if the buyer defaults, recovering the business in a contractor context is operationally complex and legally costly
  • Buyers may offer lower headline prices in exchange for full seller financing, as they are absorbing no institutional leverage discipline
  • Difficult to implement when the business has existing equipment financing or asset-backed loans that must be satisfied at close

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.

Sample Deal Structures

Buyer equity: $315,000 (15%) | SBA 7(a) loan: $1,680,000 (80%) | Seller note on standby: $105,000 (5%)

10-year SBA loan at WSJ Prime + 2.75%. Seller note at 6% interest, 24-month standby, then 36-month amortization. Asset purchase includes owned equipment fleet appraised at $480,000 FMV. Seller remains as paid consultant for 12 months at $8,000 per month for client transition and estimating support. No earnout — backlog fully documented with $1.4M in signed contracts.

Masonry Contractor with Key-Man Risk and Verbal GC Pipeline

$1,600,000

Buyer equity: $240,000 (15%) | SBA 7(a) loan: $1,200,000 (75%) | Seller carry: $160,000 (10%) earnout over 18 months

Base purchase price of $1,440,000 at close, with $160,000 earnout tied to gross margin performance from converted backlog over the following 18 months. Earnout pays in two tranches: $80,000 at month 9 if trailing revenue exceeds $600,000 from pre-close client relationships, and $80,000 at month 18 if cumulative gross margin from those clients exceeds 28%. Seller stays on full-time for 6 months at market salary to complete active jobs and introduce buyer to top five GC contacts.

Decorative and Stamped Concrete Business — Premium Specialty Niche

$3,400,000

Buyer equity: $510,000 (15%) | SBA 7(a) loan: $2,720,000 (80%) | Seller note: $170,000 (5%)

4.2x SDE multiple reflecting specialty decorative concrete capabilities, brand reputation, and documented recurring commercial client relationships with three regional developers. Asset purchase includes proprietary stamping equipment, color systems inventory, and customer database. Seller note subordinated 24 months, then paid over 36 months at 6.5%. Buyer negotiates a 12-month non-compete covering a 75-mile radius. Seller transitions to advisory role for 90 days at no additional cost as condition of full seller note.

Negotiation Tips for Concrete & Masonry Deals

  • 1Request a full equipment inventory with purchase dates, maintenance logs, and current liens before submitting an LOI — deferred maintenance on mixers, screeds, and concrete pumps is a common hidden liability that can erode post-close margins quickly.
  • 2Push for a detailed backlog report distinguishing signed contracts from verbal GC commitments. Only signed, executable contracts should be included in business value calculations — verbal pipeline is better addressed through an earnout rather than an inflated base price.
  • 3Negotiate the seller's transition commitment in writing as part of the purchase agreement, not as a side arrangement. Specify that the seller will complete active jobs, introduce the buyer to the top 10 GC and developer contacts, and transfer estimating documentation within a defined timeline.
  • 4If the business has revenue concentration risk — one GC relationship representing more than 25% of annual revenue — structure a portion of the purchase price as an earnout tied specifically to that relationship's continued volume in the 12 months post-close.
  • 5Use the equipment appraisal as leverage in final price negotiations. An independent FMV appraisal often reveals replacement cost gaps or deferred capital needs that justify a purchase price reduction of $50,000–$200,000 on a mid-size equipment fleet.
  • 6Clarify bonding capacity transfer early in the process. Many concrete and masonry businesses carry bonding lines tied to the individual owner's personal financials. Buyers need to establish their own bonding capacity before close, and delays here can kill deals or create gaps in the business's ability to bid commercial and municipal projects.

Frequently Asked Questions

What is the typical purchase price multiple for a concrete or masonry business?

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.

Can I use an SBA loan to buy a concrete contractor business?

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.

Why is an asset purchase preferred over a stock sale in concrete and masonry 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.

How does an earnout work in a concrete business acquisition?

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.

What happens to bonding capacity when a concrete contractor is acquired?

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.

How long does it take to close an acquisition of a concrete or masonry business?

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.
