How to Sell a Security Guard Business in 2026: 4-7x EBITDA, Named Buyers, and the Recurring-Contract Premium

When you sell a security business in 2026, a contract guard firm typically clears 4-7x EBITDA per the tiered multiples below, with recurring contract revenue, guard licensing, insurance coverage, and workers comp experience mod driving where you land inside that band. Named consolidators actively acquiring include Allied Universal (Warburg Pincus + CDPQ), Securitas, GardaWorld, and PE-backed regional platforms. The security services sector is deep in a consolidation cycle where scale and clean compliance history command real premium.

A US security guard business in 2026 typically sells for roughly 3x to 8x EBITDA, varying by customer mix, contract durability, geographic density, and platform scale. By profile: a single-state contract security firm at $300-700k SDE goes 2.5x-4x SDE; a profitable single-state or small multi-state firm with diversified customer base ($500k-1.5M SDE) goes 3x-5x SDE; a small multi-state contract security platform ($1.5-4M EBITDA) goes 4x-6x EBITDA; a regional platform ($4-12M EBITDA, multi-state, multi-vertical, named multi-year contracts) goes 5x-7x; a premium scale platform ($12M+ EBITDA, multi-state, specialized verticals such as healthcare or financial security, modern operating system) reaches 6x-8x+. Active buyers include Allied Universal (Warburg Pincus + Caisse de depot et placement du Quebec [CDPQ], ~800,000+ employees, the largest US security services company after acquiring G4S in 2021 for ~$5B), GardaWorld (BC Partners, $5B+ revenue, the second-largest global contract security platform), Securitas AB (STO: SECU-B, $14B+ revenue Swedish public, large US presence), Constellis Holdings (Triton Partners, high-risk/government security), Andrews International, Pinkerton (Securitas subsidiary), BEST Crowd Management, Universal Protection Service, Inter-Con Security (private), Whelan Security, plus PE-backed regional consolidators (BC Partners, Warburg Pincus, Triton Partners, BlackRock-backed platforms, plus business-services PE funds). The biggest multiple drivers are contract durability (multi-year contracts with named customers), specialized vertical mix (healthcare, financial services, data center, critical infrastructure premium to general retail/commercial), customer-base concentration management, modern operating system (TrackTik, Silvertrac, Officer Reports, Salus, Valor), and licensed/trained guard pool depth. No fee to you on buy-side introductions; sell-side mandates are paid on success at closing.

If you own a contract security guard business in 2026, whether that is a single-state local operator, a regional multi-state platform, or a specialized vertical operator (healthcare, financial, data center, critical infrastructure), the M&A market is mature and highly consolidated. Allied Universal (Warburg Pincus + CDPQ) operates the dominant US platform with ~800,000+ employees, having acquired G4S in 2021 for ~$5B. GardaWorld (BC Partners) and Securitas (STO: SECU-B) are the other global giants with significant US presence.

What the asset is worth depends on three things: (1) contract durability (multi-year contracts with named customers, especially commercial real estate, healthcare, education, government), (2) specialized vertical mix (healthcare, financial services, data center, critical infrastructure command premiums to mixed commercial/retail), and (3) operational scale, licensed/trained guard pool, modern operating system, regulatory compliance. This guide covers real multiples by profile, the named buyers transacting, and the operator-level diligence buyers will run.

The operator-level KPI playbook buyers will diligence

Contract base and durability

• Contract base: Total active contracts, average contract value, total billable hours per week.
• Contract terms: Multi-year vs. annual vs. month-to-month. Multi-year contracts are the multiple-builder.
• Customer concentration: No single customer above 25% of revenue.
• Customer industry mix: Commercial real estate, healthcare, financial services, retail, education, government, residential, data center, critical infrastructure, hospitality, manufacturing.

Specialized vertical exposure

• Healthcare: Hospital security, MICA security, behavioral health security, healthcare-specific training documented.
• Financial services: Bank security, armored car, currency processing.
• Data center / critical infrastructure: CISA-aligned guard training, named hyperscaler contracts.
• Government: Federal contracts (GSA schedule), state/municipal contracts, clearance-required positions.

Operational

• Guard hours per week: Total billable hours; track by site and contract.
• Guard count and tenure: Documented headcount, tenure distribution, turnover rate.
• Average bill rate vs. pay rate: Track margin.
• Overtime as % of total hours: Manageable; high overtime indicates staffing problems.
• Guard-to-supervisor ratio.

Regulatory and licensure

• State security business licensing: Documented current in every state of operation.
• Guard licensing: State-specific guard cards / PSO licenses; documented current for every guard.
• Specialized training: Healthcare security (IAHSS), financial services, executive protection, firearms (where licensed).
• Workers’-comp experience modification rate (EMR): Documented; lower is better.

Operating system and technology

• Guard tour / incident reporting: TrackTik, Silvertrac, Officer Reports, Salus, Valor, GuardMetrics. Modern systems integrate billing, scheduling, and incident reporting.
• Scheduling system: Documented scheduling tool with overtime management.
• Customer portal: Customer-facing incident reporting and dashboard access.

Workforce and compliance

• Background checks and drug testing: Documented for every guard.
• Training records: Initial training, ongoing training, specialty training documented per guard.
• Workers’-comp claim history: 3-5 year claim history; EMR below 1.0 preferred.
• Union vs. non-union staffing.

Dangers and traps in security guard M&A

1. Single-customer concentration

Single customer above 25% of revenue gets repriced as concentration risk; if above 40%, may be deal-killing.

2. Month-to-month-only contracts

Premium multiples require multi-year contract durability.

3. Workers’-comp claim history

Elevated workers’-comp claim history (EMR above 1.0) signals operational quality issues and translates to higher buyer-cost-of-coverage.

4. Guard licensing and training documentation gaps

Every guard’s licensure (state PSO / guard card), training records, and background-check documentation must be current and on file.

5. Owner-operator dependence

If the owner is the relationship manager for top customers, build the BD/account-management bench.

6. Legacy operating systems

Modern guard tour / incident reporting (TrackTik, Silvertrac, etc.) is the multiple-builder. Paper-based or legacy systems trigger integration discount.

7. Unionization expectations mismatch

Allied Universal operates union and non-union; some PE-backed regional platforms are strictly non-union. Match buyer expectations.

8. Pay-rate compression and labor shortage

Document wage trends and labor cost recovery in contracts; pass-through pricing is a multiple-protection lever.

Our POV on security guard M&A in 2026

• Single-state local operators ($300-700k SDE) sell at 2.5x-4x SDE.
• Profitable diversified single/small multi-state firms go 3x-5x SDE.
• Small multi-state platforms ($1.5-4M EBITDA) are in the tuck-in sweet spot for the public/strategic and PE-backed platforms. 4x-6x EBITDA.
• Regional platforms ($4-12M EBITDA, multi-state, multi-vertical, named multi-year contracts) reach 5x-7x EBITDA.
• Premium scale platforms ($12M+ EBITDA, multi-state, specialized vertical mix, healthcare, financial, data center, critical infrastructure) achieve 6x-8x+.

The right time to prepare is 12-18 months before going to market, build specialized vertical exposure, lock in multi-year contracts, modernize operating system, document training and licensure, and address workers’-comp claim history.

Preparing your security guard business for sale: 12-18 months out

1. Get multi-year audited or reviewed financials. Track revenue by customer, by vertical, by contract type.
2. Build specialized vertical exposure. Healthcare, financial services, data center, critical infrastructure.
3. Lock in multi-year customer contracts. Documented renewal terms, escalators tied to wages.
4. Diversify customer concentration. No customer above ~25%.
5. Document training and licensure. Every guard’s licensure, training records, background checks current.
6. Address workers’-comp claim history. Improve safety programs, reduce EMR below 1.0.
7. Modernize the operating system. TrackTik, Silvertrac, Officer Reports, Salus, Valor.
8. Build the BD/account-management bench. Reduce owner-operator dependence.
9. Document add-backs and KPIs.
10. Run a competitive process. Allied Universal (Warburg Pincus + CDPQ), GardaWorld (BC Partners), Securitas, Constellis (Triton), Inter-Con, BEST, Universal Protection Service, plus PE sponsors directly.

How to sell a security business: the sale process step by step

To sell a security business, document every guard contract with its term, bill rate, and pay rate, confirm how your state guard license transfers, then take a confidential package to strategic consolidators and PE-backed platforms under NDA. Pick a letter of intent on price and structure, clear diligence on contracts, wage-and-hour compliance, and workers’ comp, then close.

1. Confirm what can transfer. In many states a guard agency or private patrol operator license is issued to the owner or entity and cannot simply be assigned to a buyer. That pushes many deals toward a stock purchase, or forces the buyer to secure its own license before closing. Check with your state licensing board early, because it shapes the deal structure and the timeline.

2. Build the contract file. Buyers price a guard company off its contracts, not its revenue line. Prepare a schedule of every active contract with start date, renewal terms, termination notice, billable hours, bill rate, pay rate, and any change-of-control or assignment clause. Add guard turnover, your workers’ comp experience mod history, and three years of financial statements.

3. Go to market confidentially. Guard turnover and client poaching are real risks if word gets out. Buyers see a blind teaser first, sign an NDA, then receive the full information package. The buyer pool for most firms is the strategic consolidators named on this page plus PE-backed regional platforms looking for tuck-ins in new states or verticals.

4. Compare letters of intent on structure, not just price. Guard deals often carry part of the price in an earnout or holdback tied to contract retention after close. A higher headline number with a long retention earnout can be worth less than a lower, mostly cash offer.

5. Clear diligence. Expect questions on overtime and meal-break compliance, guard licensing and training records, open claims, insurance history, and which contracts need client consent to transfer.

6. Close and transition. Plan client introductions and a guard retention message for the week of closing, so posts stay covered and accounts stay put.

Frequently asked questions

What is the typical multiple for a security guard business in 2026?

Single-state local operators ($300-700k SDE) typically sell at 2.5x-4x SDE. Profitable diversified single/small multi-state firms ($500k-1.5M SDE) go 3x-5x SDE. Small multi-state platforms ($1.5-4M EBITDA) go 4x-6x EBITDA. Regional platforms ($4-12M EBITDA, multi-state, multi-vertical) go 5x-7x. Premium scale platforms ($12M+ EBITDA, specialized vertical mix) reach 6x-8x+.

Who are the active buyers of security guard businesses right now?

Allied Universal (Warburg Pincus + Caisse de depot et placement du Quebec [CDPQ], the largest US contract security platform with ~800,000+ employees globally; acquired G4S in 2021 for ~$5B), GardaWorld (BC Partners, $5B+ revenue), Securitas AB (STO: SECU-B, $14B+ revenue, owns Pinkerton), Constellis Holdings (Triton Partners, government/high-risk), Inter-Con Security, Andrews International, BEST Crowd Management, Universal Protection Service. PE sponsors: Warburg Pincus + CDPQ, BC Partners, Triton Partners.

What hurts a security guard business’s valuation most?

Single-customer concentration above 25%, month-to-month-only contracts without multi-year durability, elevated workers’-comp claim history (EMR above 1.0), weak licensure and training documentation, retail/commercial-only revenue without specialty vertical mix, legacy paper-based operating systems, owner-operator dependence, and unionization expectations mismatch with buyer.

Why are specialized verticals (healthcare, financial services, data center) premium?

Specialized verticals require specific training (healthcare security through IAHSS, financial security through bank-specific protocols, data center security through CISA-aligned training), have higher barriers to entry, command higher bill rates, and typically come with multi-year contracts that are harder to displace. These verticals command 1-2 turn EBITDA premium over mixed commercial/retail security.

What is workers’-comp EMR and why does it matter?

Workers’-comp experience modification rate (EMR) measures your historical workers’-compensation claim severity relative to industry average. EMR of 1.0 is average; below 1.0 is better; above 1.0 is worse. Lower EMR translates to lower insurance costs and signals operational quality. Buyers price this directly into the multiple.

Do I have to pay a broker fee?

It depends on the mandate. CT Strategic Partners works both sides of the table and is not a business broker. When a buyer from our network approaches you through a buy-side search, you pay no fee; when you hire us to run a sell-side process, we are paid on success at closing, with terms agreed in writing before any work starts.

How long does it take to sell a security guard business?

Once you go to market with an M&A advisor, a typical process runs 4-7 months from initial outreach to closing. Add 12-18 months of preparation work before going to market.

When should I start preparing if I plan to sell in 2027 or 2028?

12-18 months before going to market is the right window. Highest-leverage pre-sale work: build specialized vertical exposure, lock in multi-year contracts, modernize operating system, document training and licensure, and address workers’-comp claim history.

Are security guard companies profitable to own?

They can be, but margins live in the gap between the bill rate you charge and the wage you pay each guard. Firms that pass wage increases through to clients quickly, hold multi-year contracts, and keep workers’ comp claims low earn more and sell for more. Firms on month-to-month contracts that absorb wage hikes see thin margins and lower multiples.

Does my security guard license transfer to the buyer when I sell?

Often it does not. Many states license the guard agency to a named owner or qualifying manager, and the license cannot be assigned in an asset sale. Buyers handle this by buying the company’s stock, keeping a licensed qualifier in place, or getting their own state license before closing. Confirm the rules with your state licensing board before you sign a letter of intent.
