Selling a Security Guard Business in 2026: Multiples, Named Buyers, and the Operator Playbook
Quick Answer
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. Buyer-paid M&A advisory (CT Strategic Partners) costs the seller nothing.
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.
What this guide covers
- Security guard multiples 2026: 2.5x-4x SDE for single-state local, 3x-5x SDE for profitable diversified single/small multi-state, 4x-6x EBITDA for small multi-state platforms, 5x-7x for regional platforms, 6x-8x+ for premium scale platforms with specialized vertical exposure.
- Active buyers: Allied Universal (Warburg Pincus + CDPQ, 800,000+ employees, acquired G4S 2021 ~$5B), GardaWorld (BC Partners, $5B+ revenue), Securitas AB (STO: SECU-B, $14B+ revenue Swedish public), Constellis (Triton Partners, government/high-risk), Pinkerton (Securitas subsidiary), BEST Crowd Management, Universal Protection Service, Inter-Con Security.
- PE sponsor activity: Warburg Pincus + CDPQ (Allied Universal), BC Partners (GardaWorld), Triton Partners (Constellis), plus multiple business-services PE funds.
- Multiple drivers: multi-year contract durability, specialized vertical mix (healthcare, financial services, data center, critical infrastructure), customer-base concentration management, modern operating system (TrackTik, Silvertrac, Officer Reports, Salus, Valor), licensed/trained guard pool depth.
- Things that compress the multiple: single-customer concentration, no multi-year contracts (month-to-month only), retail/commercial-only without vertical specialty, weak licensure and training documentation, workers’-comp claim history, legacy operating systems, owner-operator dependence, unionization in non-union buyer expectation states.
- Sellers pay nothing on CT Strategic Partners’ buyer-paid advisory.

- Will compress or reject: single-customer concentration above 25%, month-to-month-only contracts, retail/commercial-only without specialty mix, weak licensure or training documentation, elevated workers’-comp claim history, legacy operating systems (paper-based reporting), owner-operator dependence, undocumented add-backs, unionization where buyer expects non-union (or vice versa).
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.

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?
No. CT Strategic Partners runs a buyer-paid M&A advisory model. The seller pays nothing. The buyer pays the success fee at closing.
How long does it take to sell a security guard business?
Once you go to market with a buyer-paid 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.
