Security, Alarm & Monitoring: Business Valuation & Sale Guide

How Security, Alarm & Monitoring Companies Are Valued

Smaller dealer-model alarm companies are commonly assessed on SDE, while operators with an owned central station or multi-branch structure are more naturally evaluated on normalized EBITDA. A buyer will separate RMR from installation and service revenue, test the attrition rate against the RMR multiple already paid to acquire accounts, and confirm whether monitoring is self-performed or wholesaled to a third-party central station.

OwnerGauge applies a reviewed security-monitoring-specific multiple range to the assessment, informed by public 2025-2026 benchmark data — RMR-based revenue streams command a premium similar to other subscription-style service businesses, provided attrition and contract assignability hold up under diligence.

Revenue Quality in Security, Alarm & Monitoring

• —RMR is the core asset in this category; buyers weight attrition and contract enforceability far more heavily than gross account count.
• —Installation and one-time service revenue support the business but do not carry the multiple the way RMR does.
• —Commercial and government monitoring contracts tend to be stickier and higher-margin than residential accounts, but also carry longer sales cycles and more compliance overhead.

Owner Dependency

• —The owner often holds the dealer-program relationships, central-station contracts, and licensing that let the business monitor accounts across jurisdictions.
• —A buyer tests whether licensing, permitting, and central-station relationships transfer cleanly, and whether sales and service run through anyone besides the owner.

Management & Workforce

• —Technician licensing requirements vary by state and can constrain how quickly the business can expand into new territories.
• —Buyers look for documented installation quality, service response times, and a sales function that isn't solely the owner's relationships.

What Can Make the Business More Attractive

• —Lower attrition through proactive account retention and service-quality tracking
• —Improve cost-per-RMR-dollar acquired in the sales and installation process
• —Grow commercial and government account share relative to residential
• —Document licensing and permitting coverage across every jurisdiction served

What Can Influence Valuation

• —RMR base size, attrition rate, and cost-per-RMR-dollar acquired
• —Contract term, assignability, and early-termination language
• —Self-performed versus wholesale central-station monitoring
• —UL-listing, licensing, and certification coverage by jurisdiction
• —Residential versus commercial and government account mix

What Buyers May Evaluate

• —RMR attrition rate against the multiple paid to build the book
• —Contract assignability and early-termination exposure on change of ownership
• —Central-station relationship terms if monitoring is outsourced
• —Licensing and UL-listing compliance across every jurisdiction served

Common Transaction Risks

• —Attrition is understated because it is measured inconsistently or infrequently
• —Contracts are not clearly assignable to a new owner without customer consent
• —Central-station or dealer-program agreements contain change-of-control clauses
• —Licensing lapses in one or more jurisdictions surface during diligence

Preparing the Company for Sale

• —Report RMR, attrition, and cost-per-RMR-dollar acquired on a consistent, defensible basis
• —Review contracts for assignability and early-termination language before going to market
• —Confirm licensing and UL-listing status in every jurisdiction served
• —Document central-station and dealer-program agreements and any change-of-control provisions
