From SBA-financed buyouts to equity recaps with earnouts, understand the deal structures that close in the private security sector — and how contract quality, license transferability, and workforce stability shape every term.
Acquiring a private security services company involves navigating a labor-intensive, contract-driven business where deal structure is inseparable from operational risk. Unlike asset-light acquisitions, security firm deals require buyers to address contract assignability, state licensing transfer, workers' compensation tail coverage, and employee retention — all of which directly influence how purchase price is paid, how risk is allocated between buyer and seller, and how long a seller remains involved post-close. In the lower middle market ($1M–$5M revenue), security companies typically trade at 3.5x–6x EBITDA, with valuation clustering around contract quality, customer concentration, and the strength of middle management. The most common structures in this sector include SBA 7(a) financed full buyouts with seller notes, full acquisitions with transition consulting agreements, and equity recapitalizations where the seller retains a minority stake under a PE sponsor. Each structure reflects the realities of a 24/7 operational business where day-one continuity — of guard deployments, client relationships, and licensing — is non-negotiable.

The most common structure for first-time buyers and search fund operators acquiring security companies under $5M in revenue. The buyer injects 10–20% equity, the SBA 7(a) loan covers 70–80% of the purchase price (up to $5M), and the seller carries a note representing 10–20% of the deal — which is often required by SBA lenders to demonstrate seller confidence in the transition. The seller typically signs a 6–12 month consulting agreement to support license transfers, client introductions, and workforce continuity.
Pros
Cons
Best for: Entrepreneurial buyers with law enforcement or military backgrounds acquiring their first security firm, or operators purchasing a retiring owner's established regional patrol or guarding business with clean financials and diversified contracts.
Full Acquisition with Seller Note and Transition Consulting Agreement
A conventional buyout where the buyer (often a strategic acquirer or regional security company) pays a significant portion of the purchase price at close in cash, with the seller carrying a subordinated note of 10–20%. The seller remains engaged under a paid consulting agreement for 6–12 months to manage client relationship handoffs, supervise guard supervisors, and support licensing transitions. No SBA financing is involved — the buyer funds the acquisition through a combination of equity and senior bank debt.
Pros
Cons
Best for: Regional or national security companies making bolt-on acquisitions for geographic expansion, or experienced operators with existing security operations who can absorb a target's workforce and contracts into an established platform.
Equity Recapitalization with PE Sponsor and Seller Earnout
A private equity sponsor acquires a majority stake (typically 60–80%) in a security firm, with the seller retaining 20–40% equity and rolling proceeds into the new entity. The seller continues as an operating partner or CEO and participates in an earnout tied to contract retention rates and EBITDA growth over 2–4 years. This structure is most common when a PE firm is building a platform through add-on acquisitions and wants the founder's operational expertise, client relationships, and local market reputation to anchor the combined entity.
Pros
Cons
Best for: Founder-operators aged 50–65 with strong client relationships and a capable management team who want to monetize a significant portion of their equity now while participating in a larger platform exit in 4–7 years under a PE sponsor.

Security services companies with $1M–$5M in revenue typically trade at 3.5x–6x EBITDA, with the wide range reflecting the significant variance in contract quality and duration. Operators with multi-year contracts with government, healthcare, or institutional clients and customer concentration below 20% per client command multiples at the higher end. Businesses with month-to-month agreements, high turnover above 100% annually, or a single client representing 30%+ of revenue typically price at 3.5x–4.5x to compensate for elevated transition risk.
Yes, security services businesses are eligible for SBA 7(a) financing, and it is the most common acquisition financing structure for individual buyers in this sector. Lenders will scrutinize the contract base — specifically contract length, renewal history, and customer concentration — as the primary basis for debt service coverage analysis. Buyers typically need to inject 10–20% equity, and SBA lenders generally require the seller to carry a subordinated note of at least 10% of the purchase price to demonstrate confidence in the transition. State licensing transferability and workers' compensation history will also be reviewed during SBA underwriting.
In security services M&A, earnouts are most commonly structured around contract retention rates and EBITDA performance over a 2–4 year post-close period. For example, a seller might receive up to $500,000 in additional proceeds if 90% or more of the contract base (by revenue) is retained through year two and EBITDA meets agreed thresholds. Earnouts are particularly common in PE-led equity recapitalizations where the seller stays on as an operating partner. The critical negotiating point is defining what counts as a retained contract — clients who reduce scope or renegotiate pricing should be addressed explicitly in the earnout calculation methodology.
This is one of the most operationally critical issues in any security services acquisition. Most states require guard agency licenses to be held by the business entity and may require re-application or transfer approval when ownership changes. Some jurisdictions — including California, Florida, and Texas — have specific change-of-ownership notification or re-licensing requirements. Buyers should conduct a full license audit as part of due diligence, confirm transferability with the relevant state licensing authority, and structure closing conditions around regulatory confirmation rather than assumed timelines. SBA lenders will also require evidence that licensing continuity is assured before funding disbursement.
Customer concentration is one of the most significant value killers in security services transactions. Buyers and lenders will heavily discount businesses where a single client represents more than 20–25% of revenue, as contract loss post-close creates immediate debt service risk. Sellers preparing for exit should work to diversify their client base 12–24 months before going to market, ideally targeting no single client above 15% of revenue. If concentration cannot be reduced, sellers should prioritize securing multi-year contract renewals with anchor clients prior to marketing the business, and be prepared to accept earnout provisions tied to retention of those specific accounts.
Most security services acquisitions include a 6–12 month transition period during which the seller remains involved under a paid consulting agreement. This period covers critical handoffs including introduction of the buyer to key client contacts, transfer of guard supervisor relationships, completion of state licensing transfers, and documentation of dispatch and incident response protocols. In PE equity recapitalizations, sellers often continue as the operating president for 2–4 years while the platform executes add-on acquisitions. The scope and compensation of the transition role should be documented in the purchase agreement — vague consulting arrangements are a common source of post-close conflict in service business acquisitions.
