Letter of Intent Template for Acquiring a Construction Business

A contractor-specific LOI framework covering backlog quality, bonding continuity, key-man transition, and deal structure — built for buyers acquiring $1M–$5M revenue construction companies.

An LOI for a construction company acquisition is not a generic document. Unlike a SaaS business or a retail store, a contractor acquisition involves project-based revenue, open work-in-progress, bonding and licensing contingencies, and deep owner dependency in estimating and client relationships. Your letter of intent must address these realities upfront to set clear expectations, protect your diligence rights, and establish a deal framework that survives the complexity of closing a construction transaction. This guide walks through each section of a construction-specific LOI, provides example language calibrated to lower middle market contractors in the $1M–$5M revenue range, and highlights the negotiation dynamics unique to buying an owner-operated specialty or general contracting business.

LOI Sections for Construction Acquisitions

Purchase Price and Valuation Basis

State the proposed total enterprise value and how it was derived — typically a multiple of trailing twelve-month EBITDA adjusted for owner compensation normalization, one-time project charges, and personal expenses run through the business. For construction businesses, clarify whether the purchase price includes or excludes net working capital, open receivables, and work-in-progress balances.

Example Language

Buyer proposes to acquire substantially all of the assets of [Company Name] (the 'Company') for a total purchase price of $[X], representing approximately [X.Xx] times the Company's adjusted EBITDA of $[X] for the trailing twelve months ended [Date]. The purchase price is predicated on a normalized EBITDA calculation that adds back excess owner compensation above $[X], personal vehicle expenses of $[X], and non-recurring project write-offs of $[X]. The final purchase price shall be subject to a working capital adjustment mechanism to be negotiated during due diligence, with a target working capital peg of $[X] based on the average of the prior four fiscal quarters.

💡 Construction sellers frequently push back on EBITDA adjustments, particularly when personal expenses are intertwined with legitimate project costs. Come prepared with a detailed add-back schedule sourced directly from job cost reports and P&L line items. Sellers also often argue for a higher working capital peg if there is significant unbilled receivables or retainage outstanding. Negotiate a clear definition of what is included in working capital — specifically whether retainage receivable, overbillings, and underbillings are included or treated separately.

Deal Structure and Payment Terms

Define how the purchase price will be paid — including the cash at close, SBA loan proceeds, seller note amount and terms, and any earnout tied to post-close backlog conversion or gross margin performance. Construction acquisitions commonly include holdback escrows to address post-close warranty claims and project close-outs.

Example Language

The proposed purchase price of $[X] shall be funded as follows: (i) $[X] in cash at closing funded through SBA 7(a) loan proceeds; (ii) $[X] equity injection from Buyer; (iii) a seller promissory note of $[X] bearing interest at [X]% per annum, payable over [24–36] months, subordinated to the SBA lender; and (iv) an earnout of up to $[X] payable over 12 months post-close contingent upon the conversion of signed backlog contracts existing as of the closing date achieving gross margins at or above [X]%. Additionally, $[X] (representing [X]% of the purchase price) shall be held in escrow for 18 months post-close to satisfy any valid warranty claims, mechanic's liens, or project dispute liabilities arising from work performed prior to closing.

💡 Sellers in construction deals are particularly sensitive to earnouts tied to backlog conversion because project timing is often outside their control. If you include a backlog earnout, tie it to gross margin dollars earned on transferred contracts rather than revenue recognized, and set a reasonable time horizon of 12–18 months. The escrow holdback is often a contentious point — sellers want it released quickly, buyers want it held until all active projects at close have been substantially completed and the lien period has passed. A tiered release schedule tied to project close-out milestones is often a workable compromise.

Assets Included and Excluded

Specify what is being acquired — licenses, contracts, equipment, vehicles, tools, trade name, customer relationships, subcontractor agreements, and any real estate leases. Explicitly exclude personal assets, owner-retained real estate, and any assets with title or lien issues. For construction businesses, clarity on equipment ownership versus leased assets is critical.

Example Language

The transaction is structured as an asset purchase. Included assets shall encompass: all signed and unsigned customer contracts and purchase orders; the Company's trade name, website, and marketing materials; all owned equipment, vehicles, and tools as listed on the attached Schedule A; transferable state contractor licenses and related registrations; all subcontractor and supplier agreements; the Company's bonding history and relationships with the surety provider; and the goodwill of the business. Excluded assets include: [Owner's] personal vehicle not used in operations, any real property owned by [Owner] or related entities, cash and cash equivalents in excess of the working capital peg, and any intercompany receivables owed by related entities. Buyer shall assume no liabilities except those specifically identified in a final Assumed Liabilities Schedule.

💡 Pay close attention to equipment schedules in construction acquisitions — sellers often have equipment titled in personal names, related LLCs, or secured by UCC liens from equipment lenders. Require a full equipment list with title confirmation and lien searches as part of early diligence. Also confirm which subcontractor agreements are assignable without consent, as some GC relationships or master subcontract agreements include anti-assignment clauses that require notification or approval.

Backlog and Work-in-Progress Representation

Require the seller to represent that a complete and accurate WIP schedule will be delivered prior to close, and define how open projects, underbillings, overbillings, and retainage will be treated in the transaction. This section is unique to construction and should not be omitted.

Example Language

Seller shall, within [15] business days of LOI execution, deliver to Buyer a complete work-in-progress (WIP) schedule as of [Date], including for each open project: the original contract value, change orders executed to date, total costs incurred to date, estimated costs to complete, gross margin percentage, billed to date, and retainage withheld. Seller represents that the WIP schedule is prepared on a consistent basis with the Company's historical accounting practices and that no project reflected therein has a known material cost overrun, unresolved dispute, or pending change order dispute that would materially affect its stated margin. Buyer's obligation to proceed to closing is conditioned upon its satisfactory review of the WIP schedule and underlying job cost reports.

💡 The WIP schedule is the single most important financial document in a construction acquisition. Insist on receiving it early — ideally within two weeks of LOI execution — so you can reconcile it against the CPA-prepared financials and identify any jobs with margin fade, overbilling positions, or retainage disputes. Sellers sometimes resist sharing detailed job-level data citing competitive sensitivity; address this with a mutual NDA addendum covering project-specific information. Also watch for jobs that are nearly complete with unapproved change orders outstanding — these represent real contingent revenue risk that could affect your adjusted EBITDA.

Licensing, Bonding, and Insurance Contingencies

Make closing contingent upon confirmation that all state contractor licenses, surety bonds, and key insurance policies are either transferable to the buyer entity or can be reissued in the buyer's name with continuity of coverage. This is a structural requirement in most contractor acquisitions.

Example Language

Closing of this transaction is contingent upon: (i) confirmation from the applicable state licensing authority that [list of licenses] held by the Company or its principal can be transferred to Buyer or reissued to a Buyer-designated entity within [60] days of closing, or alternatively, that Buyer's designated qualifying agent will be approved; (ii) written confirmation from the Company's surety provider that the existing bonding program will be maintained or replaced with equivalent capacity for Buyer's entity, including open project bonds and any required bid bonds; and (iii) confirmation that the Company's general liability, workers' compensation, and builders' risk insurance policies will be continued or replaced without gap in coverage. Seller agrees to cooperate fully with Buyer in obtaining all necessary consents, applications, and approvals required to satisfy these contingencies.

💡 Bonding continuity is frequently the longest-lead-time item in a construction close. Engage the surety broker early — ideally before LOI execution if possible — to understand what financial documentation the surety will require from the buyer entity and whether the existing bonding capacity can be maintained. Some sureties will not bond a newly formed acquisition entity without a full indemnification agreement and personal financial statements from the buyer. If the seller's license is held by the owner as a qualifying agent, plan for a 30–90 day licensing transition period that may require the seller to remain as a consultant or temporary qualifying party.

Key-Man Transition and Seller's Post-Close Role

Define the seller's post-close involvement — including duration, compensation, and scope — to address the single greatest risk in most construction acquisitions: the seller's role in client relationships, estimating, and field oversight. This section protects both parties by setting clear expectations.

Example Language

Seller agrees to remain actively involved in the business following the closing date for a transition period of [12–24] months in the capacity of [Senior Advisor / Consultant / Part-Time Project Manager], compensated at a rate of $[X] per month. During the transition period, Seller shall: (i) introduce Buyer to all material customer contacts and project owners; (ii) participate in active bid and estimating review for contracts exceeding $[X] in value; (iii) support the transfer of field relationships with key subcontractors and suppliers; and (iv) provide reasonable availability for project-specific questions and dispute resolution. Seller shall not be required to perform field labor. A more detailed transition plan shall be attached as an exhibit to the definitive purchase agreement.

💡 Construction sellers often agree to a transition in principle but resist formalizing it in a binding agreement. Use the LOI to lock in the duration and structure of the transition before moving to diligence — it is far harder to negotiate post-LOI when the seller's leverage has increased. If the seller is the primary estimator, prioritize identifying and retaining a replacement during due diligence. Some buyers negotiate a portion of the seller note as contingent on the seller's completion of transition milestones, which aligns incentives without requiring a formal earnout structure.

Non-Compete and Non-Solicitation

Require the seller to agree to a reasonable non-compete and non-solicitation covenant covering the geographic markets and trade specialties of the business. In construction, geographic scope should be defined by the Company's actual project radius, not a broad state-wide restriction that may not be enforceable.

Example Language

As a condition of closing, Seller shall execute a non-compete and non-solicitation agreement restricting Seller from: (i) engaging in, owning, or operating a competing construction, contracting, or specialty trade business within [50] miles of the Company's principal office for a period of [3] years following the closing date; (ii) soliciting or accepting work from any customer of the Company for whom the Company performed services in the [3] years preceding closing; and (iii) soliciting or hiring any employee or subcontractor of the Company for [2] years following closing. The parties acknowledge that these restrictions are reasonable in light of the Company's geographic operating area, trade specialty, and the consideration being paid to Seller.

💡 Non-compete enforceability in construction is highly state-specific. Some states require the covenant to be supported by independent consideration beyond the purchase price. Tie the non-compete to the definitive agreement and make it a closing condition — not an afterthought. In deals where the seller is retaining rollover equity or participating in an earnout, the non-compete is less contentious because the seller has financial incentive to stay cooperative. For deals with no seller equity rollover, expect more resistance and be prepared to narrow the geographic scope or shorten the duration to reach agreement.

Exclusivity and Diligence Timeline

Grant the buyer a defined exclusivity period during which the seller will not solicit or negotiate with other potential acquirers, and establish a clear due diligence timeline with defined milestones for document delivery, site visits, and financing commitments.

Example Language

In consideration of Buyer's commitment of time and resources to the due diligence process, Seller agrees to grant Buyer an exclusive negotiation period of [60] days from the date of LOI execution (the 'Exclusivity Period'), which may be extended by mutual written agreement for up to an additional [30] days. During the Exclusivity Period, Seller shall not solicit, entertain, or negotiate with any other potential acquirer. Buyer shall conduct due diligence in accordance with the following milestones: document delivery within [10] business days of LOI execution; management meetings and site visits within [20] business days; SBA lender pre-approval or financing commitment within [30] business days; and delivery of a draft purchase agreement within [45] business days. Failure by Buyer to materially comply with these milestones shall entitle Seller to terminate exclusivity upon [5] business days' written notice.

💡 Construction diligence takes longer than most asset-light businesses because of the volume of project-level documentation required — job cost reports, lien waivers, subcontractor agreements, and bonding history all need to be reviewed. Request a 60-day exclusivity window at minimum, with a 30-day extension option. Sellers who have been through a failed prior process are often reluctant to grant long exclusivity periods; demonstrate credibility by arriving with an SBA lender pre-qualification letter and a detailed diligence checklist at LOI execution. Mutual milestone obligations — seller delivers documents, buyer delivers financing commitment — help keep both parties accountable.

Conditions to Closing

List the material conditions that must be satisfied before the transaction can close, including financing approval, license and bond transfers, satisfactory completion of due diligence, and execution of definitive agreements.

Example Language

The parties' obligations to consummate the transactions contemplated herein are subject to satisfaction of the following conditions prior to or at closing: (i) Buyer's receipt of SBA 7(a) loan approval and funding commitment in an amount sufficient to fund the cash portion of the purchase price; (ii) satisfactory completion of Buyer's due diligence, including review of the WIP schedule, job cost reports, three years of financial statements, and all material contracts; (iii) transfer or reissuance of all required state contractor licenses to Buyer's entity; (iv) confirmation of bonding continuity from the Company's surety provider; (v) execution of definitive asset purchase agreement, transition services agreement, and non-compete agreement by all parties; (vi) no material adverse change in the Company's financial condition, backlog, or key employee base between LOI execution and closing; and (vii) receipt of any required third-party consents, including landlord consents for lease assignments and client consents for contract assignments where required.

💡 The material adverse change clause is particularly important in construction because backlog can shift dramatically between LOI and close — a major project can be cancelled, a key project manager can resign, or a dispute can arise on a large open job. Define MAC specifically to include loss of any single contract exceeding $[X] in value, departure of named key employees, and any new lien filings or bonding claim. Sellers will push for narrow MAC definitions; buyers should hold firm on construction-specific triggers that reflect genuine business risk.

Key Terms to Negotiate

Working Capital Peg and WIP Treatment

The working capital target in a construction acquisition must explicitly address how underbillings, overbillings, and retainage receivable are treated. Underbillings represent earned but unbilled revenue — effectively an asset — while overbillings are a liability. Sellers often want underbillings included in working capital at full value; buyers should discount them based on the risk of cost overruns on the underlying projects. Negotiate a clear definition before LOI execution to avoid a protracted dispute during due diligence.

Backlog Earnout Structure and Gross Margin Threshold

If the deal includes an earnout tied to backlog conversion, define it in terms of gross margin dollars earned on transferred contracts rather than total revenue recognized. Set a minimum margin threshold (typically matching the historical average for the Company's project type) below which no earnout is paid. Cap the earnout period at 12–18 months to limit post-close complexity and ensure the seller remains motivated to support the transition during the earnout window.

Escrow Holdback Amount and Release Conditions

A holdback escrow of 5–10% of the purchase price is standard in construction acquisitions to cover post-close warranty claims, mechanic's liens, and project dispute liabilities. Negotiate the release conditions tied to specific project close-out milestones — such as receipt of final lien waivers and certificate of substantial completion on all active projects as of close — rather than a simple time-based release. A tiered release schedule allows partial release as individual projects close out, reducing seller frustration while maintaining buyer protection.

Seller Note Subordination and Standstill Provisions

If the deal includes a seller note, the SBA lender will require the seller note to be fully subordinated to the SBA loan with a standstill provision prohibiting principal and interest payments during any default period. Sellers are often surprised by the restrictiveness of SBA subordination requirements. Address this in the LOI to ensure the seller understands and accepts the subordination terms before investing significant time in due diligence.

License Qualifying Agent Arrangements

In states where the contractor license is held by a named individual rather than the entity, the buyer will need to either qualify their own designated person or negotiate a temporary qualifying agent arrangement with the seller. Define the duration, compensation, and liability protections for the seller acting as temporary qualifying agent post-close. Some sellers refuse to continue as qualifying agent after receiving sale proceeds; identify this risk early and engage a licensing consultant to evaluate alternatives in the target state.

Retainage Receivable Ownership

Retainage — typically 5–10% of contract value withheld by project owners until substantial completion — can represent a significant portion of a construction company's receivables. Negotiate whether retainage on pre-close projects is retained by the seller (collected post-close and remitted to seller) or transferred to buyer as part of working capital. Each approach has cash flow implications; model both scenarios before LOI execution and define the treatment clearly to avoid post-close disputes.

Key Employee Retention Incentives

If the business has project managers, estimators, or field superintendents who are critical to operations, negotiate a key employee retention pool funded at close — typically 1–3% of the purchase price paid to named individuals contingent on 12-month post-close tenure. Including a retention pool commitment in the LOI signals seriousness to the seller and reduces the risk of key employee departures during the diligence and transition period, which is the period of greatest vulnerability in a construction acquisition.

Common LOI Mistakes

  • Failing to request the WIP schedule before submitting the LOI — without visibility into open project margins, cost-to-complete estimates, and overbilling positions, the purchase price in your LOI is based on incomplete information. Always request a preliminary WIP schedule as part of your pre-LOI diligence and use it to stress-test the EBITDA multiple you are proposing.
  • Ignoring bonding capacity as a closing condition — many buyers treat bonding as an administrative detail to be resolved post-LOI, only to discover that the surety will not bond the new entity or requires 6–12 months of financial history before extending capacity. This can delay or kill the deal. Engage the surety broker during the LOI phase and make bonding continuity an explicit closing condition.
  • Accepting a vague seller transition agreement — writing 'seller will assist for 6 months' into the LOI without defining scope, compensation, and availability requirements leaves enormous post-close risk in a business where the owner is the primary estimator and client relationship holder. Define transition milestones, minimum hours of availability, and specific activities the seller must perform to earn any contingent consideration.
  • Using a generic asset purchase LOI without construction-specific representations — standard LOI templates do not address WIP schedules, job cost reporting, percentage-of-completion accounting, lien exposure, or backlog quality. Using a template designed for a service business or retail acquisition will leave critical construction-specific risks unaddressed and create renegotiation opportunities for the seller during due diligence.
  • Underestimating the timeline for license transfers and including an unrealistic closing date in the LOI — contractor license transfers and qualifying agent applications can take 30–90 days depending on the state and trade classification. Setting a 30-day close date in the LOI without accounting for licensing timelines creates breach risk and erodes seller confidence. Build a realistic close timeline of 90–120 days into the LOI and include extension provisions tied to licensing and bonding milestones.

Frequently Asked Questions

What is an LOI and why do I need one to buy a construction company?

A letter of intent (LOI) is a non-binding document that outlines the key terms of a proposed acquisition before the parties invest in legal fees, due diligence costs, and lender applications. In a construction acquisition, the LOI is particularly important because it establishes how you will treat open projects, WIP balances, retainage, bonding continuity, and the seller's post-close transition role — issues that are unique to the industry and can derail deals if left unaddressed until the definitive agreement stage. A well-constructed LOI also grants you exclusivity, giving you protected time to complete diligence without the seller shopping the deal to other buyers.

How should I value a construction business for purposes of the LOI purchase price?

Lower middle market construction companies typically trade at 2.5x–4.5x adjusted EBITDA. The multiple depends on backlog quality, customer diversification, margin consistency, management depth, and the presence of recurring or retainer-based revenue. To arrive at adjusted EBITDA, you need to normalize owner compensation to a market-rate replacement salary, add back documented personal expenses, and adjust for any one-time project charges or non-recurring write-offs. Construction financials are complicated by percentage-of-completion accounting, so always reconcile the income statement to the WIP schedule and underlying job cost reports before finalizing a purchase price for the LOI.

Should the LOI be binding or non-binding?

The LOI itself should be non-binding on the substantive deal terms — purchase price, structure, and conditions — to preserve flexibility during diligence. However, certain provisions should be expressly binding: the exclusivity period prohibiting the seller from negotiating with other buyers, the confidentiality obligations protecting your diligence findings and the seller's business information, and each party's obligation to negotiate in good faith toward a definitive agreement. Make the binding versus non-binding distinction explicit in the LOI language to avoid misunderstandings.

What due diligence should I complete before submitting an LOI for a construction company?

Before submitting an LOI, you should review at minimum: 3 years of tax returns and financial statements, a preliminary WIP schedule, a list of the Company's top 10 clients and revenue concentration, a summary of open and recently completed projects, confirmation of active licenses and bonding capacity, a list of owned and leased equipment, and any known disputes, liens, or claims. This pre-LOI review allows you to price the deal accurately and identify any deal-breakers before investing in exclusivity. A full due diligence checklist — covering job cost reports, subcontractor agreements, insurance history, and legal matters — should be delivered to the seller within the first week of the exclusivity period.

How do I structure the earnout in a construction company LOI?

The most effective construction earnout ties a portion of the purchase price — typically 10–20% — to the gross margin performance of the backlog that exists at close. Define the earnout as a dollar amount per gross margin point earned on transferred contracts, with a floor margin threshold below which no payment is made and a cap on total earnout exposure. Tie the measurement period to 12–18 months post-close, which should be sufficient to substantially complete the projects in backlog at closing. Avoid revenue-based earnouts in construction because revenue recognition timing is affected by billing schedules and retainage, which can be manipulated or are outside the seller's control.

What happens to open projects and subcontractor agreements when I buy a construction company?

In an asset purchase — the most common structure for lower middle market construction acquisitions — you are acquiring the contracts, not the entity. This means each open project contract and subcontractor agreement must be reviewed for assignability. Many commercial contracts and GC subcontracts require written consent from the project owner or GC before assignment to a new entity. Some may also trigger bonding requirements for the new entity. Your LOI should require the seller to identify all contracts requiring consent and to use commercially reasonable efforts to obtain those consents prior to closing. Contracts that cannot be assigned are a material risk that should affect your purchase price or deal structure.

Can I use an SBA loan to buy a construction company and how does that affect the LOI?

Yes, SBA 7(a) loans are widely used to finance lower middle market construction acquisitions and the industry is SBA-eligible. An SBA loan typically covers 70–80% of the purchase price, with the buyer injecting 10–20% equity and the balance often funded by a seller note that is subordinated to the SBA lender. In the LOI, you should disclose your intent to use SBA financing, include SBA loan approval as an explicit closing condition, and note that the seller note will be subject to SBA subordination requirements — including standstill provisions that restrict interest and principal payments during any default period. Providing the seller with an SBA pre-qualification letter at LOI submission significantly improves your credibility and reduces seller concern about deal certainty.
