Selling an Alarm Monitoring Company in 2026

Alarm monitoring is one of the few businesses valued on a multiple of revenue rather than EBITDA, and the convention, the RMR multiple, is so well established that the entire deal turns on it. The RMR multiple ranges from roughly 28x to 50x+ depending on the quality of the account book, attrition, contract terms, RMR mix, and whether you own a central station. Knowing what drives the multiple, and what to fix before a sale, is the difference between a 30x deal and a 45x deal on the same book. This guide covers the RMR-multiple math, the value drivers, the buyers, what kills deals, and the process.

We are CT Acquisitions, a buy-side M&A advisory firm with buyers in our network actively acquiring alarm monitoring companies and security platforms. Sellers pay nothing, the buyer pays our fee at closing. For adjacent verticals, see our guides on selling a fire alarm company and selling a security integration company.

The RMR-multiple math: how alarm monitoring companies are valued

Unlike most businesses, an alarm monitoring company is valued as a multiple of its recurring monthly revenue (RMR), the contracted monthly fees from monitored accounts, not as a multiple of EBITDA. The convention exists because the account book is the asset, and its value is a function of how reliably those monthly fees will keep coming.

The arithmetic: a company with $100,000 of RMR ($1.2M of annual recurring revenue) is worth roughly $2.8M at 28x, $3.5M at 35x, $4.5M at 45x. Moving from a 30x book to a 45x book, by cutting attrition, lengthening contracts, and shifting RMR mix toward commercial fire, is a 50% increase in enterprise value on the same revenue. That is the prize.

What drives the RMR multiple up or down

The central station question

Whether you own a UL-listed central station materially affects value. Owning one means: (1) the station itself is an asset (real estate/equipment/redundancy infrastructure plus the UL listing and any TMA Five Diamond certification), (2) you can generate wholesale-monitoring revenue by monitoring other dealers’ accounts, which is its own recurring stream, and (3) you control the customer relationship end to end rather than depending on a third-party wholesaler. Companies that wholesale all their monitoring trade at lower RMR multiples because they have less control and lower margins. If you own a quality central station, make sure the buyer values it separately, it is not just folded into the RMR multiple.

Who is buying alarm monitoring companies in 2026

• The large monitoring consolidators, national and super-regional companies that have spent years buying alarm-account books and central stations to build scale.
• PE-backed security platforms, private equity firms backing security-integration and monitoring rollups; security solutions sector deals have averaged roughly 11.8x EV/EBITDA over a five-year period, and multiple new large-cap PE firms entered the fire and security space in 2024.
• Fire and life safety platforms, Pye-Barker Fire & Safety (which closed roughly 41 acquisitions in 2025) and others actively acquire monitoring books, especially commercial fire monitoring, as part of building a fire-life-safety-security-monitoring continuum.
• Regional security companies, buying account books to add density.
• Account-book buyers, some buyers specialize in acquiring just the RMR portfolio (without the operating company), useful if you want to exit the accounts but keep the install/service business.

How to prepare an alarm monitoring company for sale

• Cut attrition. Every point below ~10% annual lifts the multiple. Audit why accounts cancel; tighten onboarding, contracts, and customer service. Attrition is the number-one diligence focus, and it is the number-one lever.
• Lengthen and strengthen contracts. Move customers to 3-5 year initial terms with clean auto-renewal/evergreen language that is enforceable in your states.
• Shift RMR mix toward commercial fire. Code-mandated commercial fire monitoring is the stickiest, highest-multiple RMR. Grow it.
• Clean the account data. Make sure your monitoring/billing platform accurately reflects active accounts and true RMR. An overstated RMR figure that diligence cuts is a deal-killer.
• Document the central station (if you own one), UL listing, certifications, redundancy, capacity, and any wholesale-monitoring revenue.
• Diversify concentration, no single commercial account or dealer relationship dominating.
• Clean the financials, accrual accounting, documented add-backs, and a clear RMR roll-forward (additions, attrition, net RMR by month).

What kills alarm monitoring company deals in diligence

• Overstated RMR, accounts on the books that are actually inactive or non-paying
• High attrition (above 13-15% annual) or attrition trending up
• Month-to-month or short-term contracts with weak/unenforceable renewal language
• Heavy concentration in one large commercial account or one dealer relationship
• Wholesaled monitoring with a third party that controls part of the customer relationship
• Messy account data, unclear which accounts are active
• Pure-residential DIY/self-install accounts with high churn dragging down the book quality
• Central station with lapsed UL listing or compliance issues

The process: first conversation to close

Alarm monitoring deals often move faster than other trades, roughly 60-150 days, because the asset (the RMR book) is well understood and the valuation convention is established. Days 1-14 conversation/RMR review/fit, days 14-30 buyer introductions, days 30-50 LOI (with the RMR multiple as the headline term), days 45-120 diligence (RMR audit, attrition analysis, contract review, central-station review, account-level data) and definitive agreement, days 90-150 close. Traditional broker listings take longer. See our broker alternative guide.

Frequently asked questions

How much is my alarm monitoring company worth?

Alarm monitoring companies are valued as a multiple of recurring monthly revenue (RMR), not EBITDA. In 2026, standard residential and small-commercial account books typically trade at roughly 28x to 40x RMR; high-quality books (low attrition, long contracts, owned UL-listed central station) reach 40x to 50x+ RMR; and premium commercial-fire-heavy portfolios can exceed that. So a company with $100,000 of RMR is worth roughly $2.8M to $5M+ depending on attrition, contract terms, RMR mix, and central-station ownership. Use our free valuation tool for a sector-adjusted estimate.

What is an RMR multiple?

RMR stands for recurring monthly revenue, the contracted monthly fees from monitored accounts. An alarm monitoring company is valued by multiplying its RMR by a market multiple (the ‘RMR multiple’), typically roughly 28x to 50x+ depending on the quality of the account book. The multiple captures attrition (low attrition = high multiple), contract term and renewal strength, RMR mix (commercial fire commands premiums), account vintage and concentration, and whether the company owns a central station. It is the central valuation metric in alarm monitoring M&A, the entire deal turns on it.

What drives the RMR multiple up?

Low attrition (under 8-10% annual is strong); long initial contract terms (3-5 years) with enforceable auto-renewal/evergreen language; an RMR mix weighted toward commercial fire monitoring (code-mandated, very sticky) rather than pure residential burglar (especially DIY/self-install, which churns); owning a UL-listed central station (ideally TMA Five Diamond certified) rather than wholesaling monitoring; mature, seasoned accounts past the early-attrition window; diversification across many accounts with no single account or dealer dominating; higher RMR per account; efficient account creation; and clean account data with accurate RMR reporting. Cutting attrition and lengthening contracts are usually the two biggest levers.

Does owning a central station increase the value of my alarm monitoring company?

Yes, materially. Owning a UL-listed central station means the station itself is an asset (infrastructure, the UL listing, any TMA Five Diamond certification), you can generate wholesale-monitoring revenue by monitoring other dealers’ accounts (its own recurring stream), and you control the customer relationship end to end rather than depending on a third-party wholesaler. Companies that wholesale all their monitoring trade at lower RMR multiples because they have less control and lower margins. If you own a quality central station, make sure the buyer values it separately rather than just folding it into the RMR multiple.

How do I reduce attrition before selling my alarm monitoring company?

Audit why accounts cancel, the common drivers are moves (customer relocates), price sensitivity, dissatisfaction with service or false alarms, and contract expiration without renewal. Then: tighten onboarding and the early-account experience (most attrition happens in the first year); move customers to 3-5 year contracts with clean auto-renewal language; improve customer service and false-alarm reduction; offer move-with-you transfers to retain relocating customers; and proactively re-contract accounts approaching expiration. Every point of attrition below ~10% annual lifts your RMR multiple, and attrition is the number-one thing diligence will scrutinize.

Who is buying alarm monitoring companies in 2026?

The large national and super-regional monitoring consolidators; PE-backed security platforms (multiple new large-cap PE firms entered the fire and security space in 2024); fire and life safety platforms like Pye-Barker Fire & Safety (which closed roughly 41 acquisitions in 2025) acquiring monitoring books, especially commercial fire monitoring, as part of a fire-life-safety-security-monitoring continuum; regional security companies adding density; and account-book buyers who acquire just the RMR portfolio without the operating company. CT also has buyers in its network actively acquiring alarm monitoring companies and security platforms.

Can I sell just my monitored accounts and keep my install business?

Yes, this is common. Some buyers specialize in acquiring just the RMR portfolio (the monitored-account book) without the operating company, which lets you exit the recurring-revenue accounts at a strong RMR multiple while keeping (or separately selling) the installation and service business. The trade-off: the install business without a recurring base is worth less per dollar of revenue, and you lose the customer relationships the accounts represented. Whether to sell the whole company, just the accounts, or both separately depends on your goals, a sell-side advisor can model the options.

How long does it take to sell an alarm monitoring company?

Alarm monitoring deals often move faster than other trades, roughly 60-150 days, because the asset (the RMR book) is well understood and the valuation convention (the RMR multiple) is established. The diligence focuses on auditing the RMR (confirming accounts are active and paying), the attrition rate, contract terms, and the central station. Traditional broker listings take longer; an off-market process to pre-qualified monitoring consolidators and PE-backed platforms compresses the timeline.
