Security and alarm monitoring companies often look simple from the outside: customers pay a monthly fee, alarms are monitored, equipment is installed, service calls are handled, and the owner points to recurring monthly revenue, usually shortened to RMR, as the headline value driver. Buyers, sellers, lenders, attorneys, CPAs, and investors frequently ask the same question: “What RMR multiple is this company worth?”
That question is understandable, but it is incomplete. RMR can be one of the most important signals in a security company valuation because recurring monitoring and related services can create predictable cash flow. ADT, a public company in the security and monitoring industry, reports end-of-period recurring monthly revenue as a key performance indicator and describes RMR as generated by contractual recurring fees for monitoring and other recurring services, including contracts monitored but not owned (ADT Inc., 2026). ADT also cautions that its key performance indicator calculations may not be comparable to similarly titled measures reported by other companies (ADT Inc., 2026). That caution is important for private-company valuation: even when the same acronym is used, the underlying calculation may differ.
A supportable business valuation therefore cannot stop at a headline RMR number. The appraiser must ask what the RMR represents, whether the accounts are owned and transferable, how much churn exists, whether billing is collectible, how RMR converts into EBITDA and cash flow, and whether comparable transaction evidence is reliable. The conclusion should reconcile recognized valuation methods, including the market approach, discounted cash flow, and, where appropriate, the asset approach. For a formal business appraisal, the analysis must also document purpose, standard of value, subject interest, assumptions, limiting conditions, and the evidence used to support professional judgment (American Institute of Certified Public Accountants [AICPA], n.d.; International Valuation Standards Council [IVSC], n.d.; National Association of Certified Valuators and Analysts [NACVA], n.d.).
This article explains how to value a security and alarm monitoring company without relying on unsupported generic RMR multiple tables. It focuses on the practical evidence a valuation professional, buyer, or owner should analyze before assigning weight to any RMR-based indication of value.
Quick Answer: What Drives the Value of an Alarm Monitoring Company?
The value of an alarm monitoring company is driven by the expected future cash flow from its accounts and operations, adjusted for risk. RMR is usually a central input, but it is only one input. A buyer paying for RMR is really paying for the right to receive future monitoring, service, inspection, software, or related subscription revenue after considering attrition, support costs, sales costs, contract terms, customer concentration, and transferability.
A stronger company usually has clean billing records, low and well-documented attrition, owned and transferable customer accounts, recurring revenue that converts into normalized EBITDA, diversified residential and commercial customers, reliable platform relationships, and financial statements that reconcile to the billing system. A weaker company may have the same reported RMR but suffer from high cancellations, unclear account ownership, unprofitable service obligations, manual billing, customer concentration, or installation revenue mislabeled as recurring revenue.
| Value driver | What to examine | Why it affects value | Source support |
|---|---|---|---|
| RMR base | Beginning RMR, ending RMR, additions, losses, price changes, acquired accounts | Establishes the recurring revenue starting point | ADT uses RMR as a KPI and defines it for its business (ADT Inc., 2026) |
| Attrition | Gross RMR attrition, net attrition, account churn, cancellations, reinstatements | Indicates how durable future cash flow may be | ADT defines gross customer revenue attrition for its reporting and warns KPI calculations may not be comparable (ADT Inc., 2026) |
| Ownership and transferability | Owned accounts, monitored-but-not-owned accounts, assignment rights, dealer agreements | Determines what is actually being sold and transferred | ADT’s RMR definition includes contracts monitored but not owned, showing why definitions matter (ADT Inc., 2026) |
| Profitability | Gross margin, platform fees, central-station costs, service labor, normalized EBITDA | Converts recurring revenue into economic benefit | Valuation standards emphasize method discipline and judgment (AICPA, n.d.; NACVA, n.d.) |
| Revenue mix | Monitoring, installation, equipment, inspections, service, video, access control, automation | Different revenue streams require different risk and margin assumptions | Alarm.com describes a technology-enabled security ecosystem with service-provider partners and connected services (Alarm.com Holdings, Inc., 2026) |
| Balance sheet | Debt, working capital, deferred revenue, customer deposits, vehicles, tools, inventory | Bridges enterprise value to equity value and identifies assets/liabilities | Asset approach and reconciliation are part of professional valuation discipline (IVSC, n.d.; NACVA, n.d.) |
The practical answer is this: RMR multiples can be a useful market shorthand, but the selected multiple is only supportable after analyzing RMR quality, attrition, contracts, profitability, and comparable evidence. If the comparable evidence is weak, a discounted cash flow model and normalized earnings analysis may deserve more weight.
What RMR Means in Security and Alarm Monitoring Valuation
RMR Definition and Why It Matters
RMR generally means recurring monthly revenue from monitoring and other recurring security services. In a local alarm dealer, it may include residential intrusion monitoring, commercial intrusion monitoring, fire monitoring where applicable, video services, access-control service plans, managed automation subscriptions, inspection contracts, or other monthly services. The exact definition is company-specific, and that is why a valuation professional should never assume that one company’s RMR equals another company’s RMR.
ADT’s 2025 Form 10-K is useful because it demonstrates how an industry participant defines and uses the metric. ADT states that end-of-period RMR is generated by contractual recurring fees for monitoring and other recurring services, including contracts monitored but not owned, and that it uses RMR to evaluate sales, installation, and retention performance and to forecast future revenue performance because most of its revenue is recurring (ADT Inc., 2026). That does not mean every private company should copy ADT’s definition. It means that RMR must be defined clearly before it is valued.
For a private business appraisal, the appraiser should request management’s definition of RMR and then test it against billing reports, general ledger revenue, customer contracts, and bank deposits. If the company includes month-to-month monitoring fees but excludes inspection contracts, the analysis should say so. If the company includes monitored-but-not-owned accounts, the appraiser should identify those accounts separately. If the company includes temporary promotional fees, paused accounts, delinquent accounts, or installation financing charges, the appraiser should decide whether those items are recurring and collectible enough to include.
RMR Is Not the Same as Revenue, EBITDA, or Value
RMR is a monthly run-rate metric. Annualizing it can provide a recurring revenue estimate, but annualized RMR is not the same as total revenue. Many security companies also earn installation revenue, equipment sales, service and repair revenue, inspection fees, project revenue, or wholesale monitoring fees. Some of those streams are recurring; others are project-based. A company with a large installation backlog may have high revenue but lower recurring value than a company with smaller total revenue and stronger contract retention.
RMR is also not EBITDA. EBITDA reflects earnings before interest, taxes, depreciation, and amortization, typically after normal operating expenses. Two companies with identical RMR can produce very different EBITDA if one has high platform costs, inefficient service operations, excessive truck rolls, unprofitable installation subsidies, weak pricing, or heavy sales commissions. A valuation based only on RMR can overstate value if recurring fees do not convert into cash flow.
Finally, RMR is not value. Value depends on expected future benefits and risk. It must consider debt, working capital, taxes, capital expenditures, deferred revenue, deposits, customer obligations, legal transferability, and the specific interest being valued. Professional standards sources such as AICPA’s Statement on Standards for Valuation Services, NACVA’s Professional Standards, and IVSC’s standards framework support a disciplined, documented approach rather than a single-metric shortcut (AICPA, n.d.; IVSC, n.d.; NACVA, n.d.).
Why Appraisers Avoid Blind RMR Multiple Tables
RMR multiple tables are tempting because they are easy to read and easy to quote. The problem is that a multiple without transaction context can be misleading. A quoted multiple may relate to an account sale rather than a whole-company sale. It may include or exclude working capital, equipment, deferred revenue, debt, holdbacks, earnouts, seller financing, or seller support terms tied to attrition. It may reflect residential accounts in one geography, commercial accounts in another, or acquired accounts with different contract rights.
The same RMR can carry different risk depending on whether accounts are owned, whether customers are under contract, whether assignment provisions are enforceable, whether billing is automated, whether cancellation history is documented, and whether the company has normalized EBITDA. For that reason, this article does not publish a universal current RMR multiple range. Without a credible, dated, comparable, and verified source, publishing a numeric range would create false precision. The better approach is to explain how RMR multiples are selected and adjusted when reliable market evidence exists.
The RMR Roll-Forward: The First Model Every Owner Should Prepare
A trailing RMR roll-forward is one of the most useful schedules in an alarm monitoring company valuation. It shows how recurring revenue moved from the beginning of a period to the end of a period. A good roll-forward separates organic growth, acquired accounts, price increases, upgrades, cancellations, non-pay losses, transfers, reinstatements, and billing corrections. Without this schedule, a buyer or appraiser may not know whether ending RMR grew because the company won sticky new customers, bought accounts, raised prices, reclassified revenue, or corrected old billing errors.
A basic roll-forward looks like this:
Beginning RMR
+ New organic RMR
+ Acquired RMR
+ Price increases / plan upgrades
- Lost RMR from cancellations
- Lost RMR from non-payment or write-offs
+/- Transfers, reinstatements, and billing corrections
= Ending RMR
The roll-forward should reconcile to billing reports and, over time, to revenue in the general ledger. Perfect monthly matching is not always possible because revenue recognition, billing timing, taxes, pass-through charges, installation invoices, and credits can create differences. Still, unexplained gaps are valuation red flags. If a company reports $100,000 of ending RMR in management reports but the billing system, bank deposits, and recurring revenue accounts do not support that run rate, a buyer may discount the RMR or require more diligence.
A practical roll-forward should cover at least 24 to 36 months when available. That time frame helps identify whether attrition is stable, improving, or worsening. It also helps separate normal monthly volatility from structural problems. For example, a spike in cancellations after a price increase may be acceptable if the remaining customer base is more profitable. A steady rise in non-pay losses may suggest customer quality or billing-process issues. A large addition from acquired accounts may be valuable, but it should be analyzed separately because acquired accounts may have different age, contract, attrition, and holdback characteristics.
Owners preparing for sale should build this schedule before going to market. Buyers should request it before relying on an RMR multiple. Appraisers should use it to support the forecast in a discounted cash flow model and to evaluate whether market approach evidence is comparable.
Attrition and Churn: The Core Risk in RMR Valuation
Gross Versus Net Attrition
Attrition measures lost recurring revenue or lost accounts. In alarm monitoring valuation, attrition is central because RMR is valuable only if it persists long enough to generate future cash flow. A company with low, stable attrition can support a more durable forecast than a company with rising cancellations or poorly documented churn.
The first issue is definition. ADT defines gross customer revenue attrition in its reporting as RMR lost as a result of customer attrition, net of dealer charge-backs and reinstated customers, excluding contracts monitored but not owned and self-setup/DIY customers (ADT Inc., 2026). That definition is specific to ADT’s reporting. A private dealer might calculate gross attrition differently, include different customer categories, or report account churn instead of RMR churn. ADT’s own caution that KPI calculations may not be comparable reinforces the point: never benchmark attrition until you know the exact formula (ADT Inc., 2026).
Gross attrition usually focuses on losses before offsetting new sales. Net attrition or net growth may consider new RMR, price increases, upgrades, or expansions. A company can show net RMR growth even while losing many customers if it adds enough new accounts. That may be acceptable when customer acquisition is efficient, but it can also hide weak retention. For valuation, both gross and net movements matter.
Account Attrition Versus RMR Attrition
Account attrition counts lost customers or accounts. RMR attrition measures lost recurring dollars. The distinction matters because not all accounts are equal. Losing one large commercial account may reduce RMR more than losing several small residential accounts. Conversely, a company may lose many low-fee accounts with limited impact on RMR.
An appraiser should review both metrics when data are available. Account attrition helps identify customer-service, product-fit, or competitive issues. RMR attrition shows the dollars at risk. Segmenting attrition by residential, commercial, fire, video, access control, wholesale, and inspection categories can reveal which revenue streams are stable and which require more conservative forecasting.
Cancellation Categories and Valuation Implications
Not all cancellations have the same meaning. A move-related residential cancellation may be a normal part of the business model. Non-pay cancellations may indicate weak customer screening, poor collection processes, or economic stress in the customer base. Cancellations at contract expiration may suggest renewal problems. Technical dissatisfaction may indicate service quality issues or outdated equipment. Large commercial cancellations may create concentration risk.
| Attrition pattern | Lower-risk interpretation | Higher-risk interpretation | Valuation response |
|---|---|---|---|
| Stable gross RMR attrition | Retention pattern appears predictable | Definitions changed or cancellations are not recorded consistently | Test formula, billing data, and cancellation logs |
| High non-pay cancellations | Isolated from a discontinued sales channel | Weak customer quality or billing discipline | Adjust forecast, working capital assumptions, and risk |
| Contract-expiration losses | Normal renewal cycle with documented replacement sales | Poor renewal process or aggressive competitors | Increase scenario testing and renewal diligence |
| Move-related cancellations | Expected residential customer behavior | Weak relocation/resale process or limited customer engagement | Analyze replacement cost and customer acquisition efficiency |
| Commercial concentration loss | Explainable one-time event | Few accounts dominate recurring revenue | Scenario-test DCF and consider concentration discount |
| Rising technical cancellations | Temporary product migration issue | Service quality, platform, or equipment obsolescence problem | Review support costs, capex, and churn assumptions |
Attrition also affects the market approach. A buyer considering an RMR multiple will usually pay more for recurring revenue that is cleanly documented and durable than for recurring revenue with high cancellations and incomplete records. But the appraiser should not convert that concept into an unsupported numeric adjustment. The adjustment should be tied to actual evidence, comparable transactions if available, and the income forecast.
Account Ownership and Transferability: What Is Actually Being Valued?
Owned Accounts Versus Monitored-but-Not-Owned Accounts
One of the most important questions in alarm monitoring valuation is whether the company owns the accounts. Some companies sell, install, service, and monitor accounts they own. Others monitor accounts originated by dealers, subcontractors, or third parties. Some accounts may be subject to dealer agreements, holdbacks, chargebacks, repurchase obligations, revenue-sharing arrangements, or restrictions on assignment. ADT’s RMR definition expressly includes contracts monitored but not owned, which illustrates why RMR definitions must be examined carefully (ADT Inc., 2026).
If a seller does not own certain accounts, the buyer may not receive the same economic rights that the RMR report implies. The monitoring company may earn a wholesale fee or service fee but not own the customer relationship. The dealer may have the right to move the account, receive a portion of revenue, or restrict transfer. A buyer paying an RMR multiple for owned accounts would view monitored-but-not-owned accounts differently.
Contracts, Billing Rights, and Customer Consent
Contract documents matter. A valuation professional is not a substitute for legal counsel, but the valuation should flag contract issues that may affect risk and marketability. Buyers and attorneys should review customer contracts, assignment provisions, renewal terms, cancellation rights, payment terms, service obligations, limitation-of-liability clauses, dealer agreements, central station agreements, platform contracts, and any customer consent requirements.
From a valuation perspective, unclear transfer rights can reduce buyer confidence and increase expected transaction costs. If accounts cannot be assigned without consent, a buyer may assume some customers will not transfer. If contracts are expired or missing, the buyer may treat the revenue as less durable. If a central station or platform agreement cannot be transferred on current terms, margin assumptions may change. These issues do not automatically eliminate value, but they can change the risk assessment.
Dealer-Originated, Acquired, and Wholesale Monitoring Accounts
Security companies often grow through multiple channels. Organic accounts may be sold directly by the company. Acquired accounts may come from account purchases. Dealer-originated accounts may have chargebacks or holdbacks. Wholesale monitoring accounts may produce recurring revenue but have different margins and ownership rights. Each category should be separated.
A strong valuation file will identify account source, contract type, account age, customer type, monthly fee, billing status, cancellation history, and any restrictions. If the company recently purchased accounts, the appraiser should review the purchase agreement, seller support obligations, attrition holdbacks, and actual post-acquisition performance. If the company services another dealer’s accounts, the appraiser should determine whether the economics resemble owned recurring revenue, wholesale service revenue, or something else.
Revenue Mix: Do Not Value Installation Revenue Like Monitoring RMR
Security companies rarely have only one revenue stream. A complete valuation should segment revenue before applying any method. Common revenue categories include:
| Revenue category | Recurring? | Main diligence questions | Valuation implication |
|---|---|---|---|
| Monitoring RMR | Usually yes | Owned? transferable? collectible? low churn? | Often central to income and market indications |
| Inspection/testing agreements | Often recurring | Renewal cycle? labor burden? required staffing? | Forecast separately from pure monitoring revenue |
| Installation/projects | Usually no | Backlog? margin history? seasonality? change orders? | Normalize; do not capitalize as RMR |
| Equipment sales | Usually no | Product margin? inventory? warranty exposure? | Affects gross margin and working capital |
| Service/repair | Sometimes repeat, not always contractual | Ticket volume? truck-roll cost? response obligations? | May support value if profitable and predictable |
| Managed video/access/automation | Often recurring | Platform dependency? data/storage costs? upgrade cycle? | Assess vendor risk, margin, and retention |
| Wholesale/dealer monitoring | Usually recurring to the company | Account ownership? contract terms? dealer concentration? | Value depends heavily on contract rights and concentration |
Alarm.com’s public filing describes a technology-enabled security ecosystem involving service-provider partners and solutions such as smart residential and commercial security, video monitoring, video analytics, automation, access control, and related recurring service opportunities (Alarm.com Holdings, Inc., 2026). That context is useful because local dealers increasingly operate within platform ecosystems. However, Alarm.com is a platform/software company, not a local alarm dealer; its filing should not be used as a direct valuation comparable for a small private company.
The key valuation point is segmentation. Monitoring revenue may support a recurring cash-flow forecast. Installation revenue may be profitable but project-based. Equipment sales may require inventory and carry warranty or support exposure. Inspection agreements may be recurring but labor-intensive. Access-control and managed video subscriptions may have platform fees or storage costs. Blending all revenue together and applying a single RMR multiple can distort value.
EBITDA and Cash Flow: The Bridge From RMR to Value
Normalized EBITDA Adjustments
RMR tells the appraiser about recurring revenue. EBITDA and cash flow tell the appraiser how much economic benefit the company produces. Normalization adjusts historical earnings to reflect the ongoing economics of the business under a market participant or expected ownership structure.
Common adjustments in a security company valuation may include owner compensation, related-party rent, nonrecurring legal or accounting costs, one-time technology migrations, integration costs from acquired accounts, discretionary vehicle or travel expenses, non-arm’s-length family payroll, unusual bad-debt expense, one-time storm or outage costs, and market-level platform or central station fees. The appraiser should support adjustments with payroll records, leases, invoices, contracts, and management explanations.
ADT reports adjusted EBITDA as one of its key performance indicators, which shows that earnings measures are relevant in security business analysis (ADT Inc., 2026). But a private-company valuation should not copy ADT’s adjustments or assume its margins apply. The appraiser must normalize the subject company’s own earnings.
Why EBITDA Margins Differ Even With Similar RMR
Two businesses can have identical RMR and very different EBITDA. Reasons include customer acquisition cost, installation subsidies, service-call frequency, central station fees, cloud platform fees, commercial versus residential mix, pricing discipline, technician productivity, support staffing, monitoring workflows, insurance costs, billing systems, and management overhead.
For example, a company that sells low-priced residential contracts with heavy equipment subsidies may need constant new sales to replace attrition and recover installation costs. Another company may have fewer accounts but higher-fee commercial services, stronger renewals, and efficient support. The first company may report similar RMR but lower normalized EBITDA and higher risk. In a business valuation, cash conversion matters as much as revenue scale.
Debt, Working Capital, Capex, and Taxes
Valuation conclusions must distinguish enterprise value from equity value. Enterprise value generally reflects the value of the operating business before considering interest-bearing debt and excess cash. Equity value reflects value to shareholders after debt, cash, and other adjustments. In transactions, working capital targets, deferred revenue, customer deposits, accounts receivable, and assumed liabilities can materially affect the price paid to the seller.
Capital expenditures also matter. Alarm companies may need vehicles, tools, installation equipment, computers, servers or networking equipment, inventory, demonstration equipment, and software systems. If historical EBITDA ignores deferred replacement needs, a discounted cash flow model should include sustainable capex. Tax assumptions also affect after-tax cash flow in a DCF model. None of these items can be captured by a simplistic RMR multiple unless the comparable transactions are extremely similar and well documented.
Valuation Methods for Alarm Monitoring and Security Companies
A credible business appraisal should consider the facts of the subject company and select appropriate methods. The three broad approaches are the income approach, market approach, and asset approach. Within those approaches, an appraiser may develop several indications and reconcile them based on relevance and reliability.
Market Approach Using RMR or Account Evidence
The market approach estimates value by reference to transactions or guideline companies. In the alarm industry, market participants may discuss account sales or company sales in terms of RMR multiples. Conceptually, the formula is simple:
Qualified RMR × Selected RMR multiple = Indicated value before required adjustments
The hard part is not the formula. The hard part is selecting a supportable multiple. A reliable comparable transaction should identify the date, account type, geography, attrition, contract status, account age, customer mix, included assets, assumed liabilities, working capital treatment, holdbacks, earnouts, seller financing, monitoring arrangements, and whether the sale involved accounts only or an entire operating company.
If the subject company has clean owned accounts, documented attrition, strong collections, and profitable recurring revenue, account-sale evidence may be relevant. If the company has mixed revenue, unclear ownership, high service costs, or substantial project work, a pure RMR indication may be less reliable. The appraiser should also avoid treating public-company data as a direct substitute for private transaction evidence. Public companies differ in size, liquidity, capital structure, reporting quality, technology, management depth, and growth profile.
Market Approach Using EBITDA or Revenue Evidence
For operating companies, EBITDA multiples may sometimes provide a better market approach than RMR multiples because EBITDA captures profitability. However, EBITDA multiple evidence has the same comparability problem: the appraiser must understand what was sold, when, under what terms, and with what risk profile. Revenue multiples may be even less reliable if revenue mix differs.
A security company with strong RMR but weak EBITDA may not warrant the same earnings multiple as a company with comparable RMR and higher margins. Conversely, a company with modest RMR but strong commercial service contracts, inspection revenue, and stable margins may require a broader earnings analysis. The best market approach is not the one with the most familiar rule of thumb; it is the one supported by reliable comparable evidence.
Discounted Cash Flow Method
The discounted cash flow method estimates value based on expected future cash flows discounted for risk. It is often useful for alarm monitoring companies because RMR can be modeled through additions, cancellations, price changes, and margin assumptions. A DCF model can explicitly show how RMR turns into revenue, EBITDA, taxes, working capital, capex, and terminal value.
A practical DCF for a security company may include these inputs:
| DCF input | Evidence to request | Common mistake |
|---|---|---|
| Starting RMR | Billing report, RMR roll-forward, customer list | Using sales pipeline instead of billed active RMR |
| Attrition | Cancellation logs, lost RMR reports, reinstatement data | Mixing account churn and RMR churn without explanation |
| New sales | Signed contracts, lead sources, historical close rates | Forecasting growth without customer acquisition cost |
| Price increases | Historical increases, customer reaction, contract terms | Assuming increases with no attrition or service impact |
| Gross margin | P&L by revenue stream, platform fees, central station costs | Treating installation and monitoring margins alike |
| Service cost | Ticket history, technician payroll, truck-roll expenses | Ignoring support burden for recurring accounts |
| Capex | Vehicle, tools, IT, and inventory needs | Treating EBITDA as free cash flow |
| Terminal value | Sustainable growth, long-term attrition, reinvestment | Assuming current growth forever |
A DCF is only as reliable as its assumptions. The discount rate should reflect company-specific risk, size, customer concentration, data quality, revenue mix, leverage, and market conditions. This article does not provide a generic discount rate because unsupported rates can be as misleading as unsupported multiples.
Asset Approach
The asset approach estimates value by identifying and valuing assets and liabilities. For a profitable alarm monitoring company with strong recurring revenue, the asset approach may not be the primary method. Still, it can be useful as a floor, a reasonableness check, or a primary method for asset-heavy, low-profit, distressed, or start-up situations.
Tangible assets may include cash, receivables, inventory, vehicles, installation tools, office equipment, computers, and leasehold improvements. Intangible assets may include customer contracts, customer relationships, trade names, software, assembled workforce, and noncompete agreements where applicable. Liabilities may include debt, accrued payroll, taxes, leases, deferred revenue, customer deposits, warranties, service obligations, and contingent liabilities.
The asset approach is especially useful for identifying what is not obvious from RMR. A company may have valuable recurring revenue but also significant debt, deferred revenue, or customer obligations. Another company may have lower RMR but valuable equipment, proprietary software, or a strong trade name. The appraiser should reconcile the asset approach with income and market evidence rather than use it mechanically.
| Method | Best use | Strength | Limitation |
|---|---|---|---|
| RMR/account market approach | High-quality account base with reliable comparable account transaction evidence | Directly addresses recurring account value | Requires detailed comparable data and adjustments |
| EBITDA market approach | Operating company with normalized earnings and comparable company-sale data | Connects RMR to profitability | Multiples may be weak or not comparable |
| Discounted cash flow | Forecastable recurring revenue and documented churn/growth data | Explicitly models drivers and risk | Sensitive to assumptions and terminal value |
| Asset approach | Asset-heavy, low-profit, distressed, or floor-check situations | Identifies tangible and intangible assets and liabilities | May understate value of profitable recurring cash flow |
How Appraisers Select an RMR Multiple Without Publishing a Generic Range
Start With Transaction Quality, Not a Headline Number
When reliable transaction evidence is available, the appraiser begins by asking what the transaction actually represents. Was it a sale of customer accounts, a sale of an operating company, a stock sale, an asset sale, or a merger? Did the buyer assume liabilities? Was working capital included? Were customer deposits or deferred revenue retained by the seller? Was the price paid upfront, or was part of it subject to holdbacks, attrition protection terms, earnouts, or seller financing? Were the accounts residential, commercial, fire, video, access control, or mixed? How old were the accounts? What was the documented attrition?
Only after answering those questions can the appraiser compare the subject company. A private business with clean recurring monitoring contracts may be closer to an account-sale comparable than a contractor-heavy integrator with large project revenue. A wholesale monitoring company with dealer concentration may require different adjustments than a direct-to-consumer residential dealer. A company with high-margin managed access-control subscriptions may not resemble a traditional intrusion-monitoring account base.
Factors That Can Support a Higher or Lower Selected Multiple
The following matrix is a qualitative guide, not a numeric pricing table:
| Factor | Stronger indication | Weaker indication | Valuation impact |
|---|---|---|---|
| Account ownership | Seller owns transferable customer accounts | Monitored-but-not-owned or unclear rights | Clear ownership lowers transaction and cash-flow risk |
| Attrition | Stable, documented, definition-consistent attrition | Rising churn, changed definitions, or data gaps | Higher attrition reduces expected future cash flow |
| Billing quality | Automated billing, low delinquency, clean A/R | Manual billing, aged receivables, frequent write-offs | Better collections improve cash-flow certainty |
| Contract terms | Clear recurring fee, renewal, assignment provisions reviewed by counsel | Missing, expired, inconsistent, or nonassignable contracts | Contract issues increase risk and diligence burden |
| Profitability | RMR converts into normalized EBITDA | RMR consumed by platform, service, and sales costs | Cash conversion drives value |
| Customer concentration | Diversified customers and account types | Few large commercial accounts dominate RMR | Concentration increases scenario risk |
| Technology/platform | Stable vendor relationships and manageable migration risk | Vendor lock-in, costly migration, outdated systems | Platform risk affects margins and retention |
| Data quality | Billing system, GL, tax returns, and bank deposits reconcile | Management reports do not reconcile | Weak data lowers confidence and may reduce weight on market multiples |
The appraiser’s job is to translate these factors into a supportable conclusion. Sometimes that means selecting and adjusting a market multiple. Sometimes it means giving limited weight to RMR multiples and relying more on the income approach. The decision should be explained in the report.
Practical Due Diligence Checklist Before a Business Appraisal
Owners who want a smoother valuation should prepare documentation before the engagement begins. Buyers should request similar information before relying on a price indication.
How to Organize the Data Room
A clean data room can change the tone of the entire valuation process. It does not by itself create a higher value, but it reduces avoidable uncertainty. The owner should organize documents by category rather than sending a single folder of mixed PDFs, spreadsheets, and screenshots. A practical structure includes folders for financial statements, tax returns, RMR reports, billing exports, contracts, customer lists, cancellation reports, service operations, sales pipeline, employees, assets, liabilities, leases, insurance, technology, and legal documents. Each folder should include a short index explaining what is included, what period is covered, and whether any information is missing.
The most important principle is traceability. A buyer or appraiser should be able to start with ending RMR, trace it to customer-level billing, compare that billing to recognized recurring revenue, and then reconcile recurring revenue to bank activity or accounts receivable. If the company uses several billing platforms because of acquisitions or legacy systems, management should explain which accounts are in each platform and whether any duplicate or inactive accounts remain. If pricing changed during the period, the data room should include effective dates and customer communication summaries.
Data-room organization also helps identify normalization issues. For example, if an owner pays a family member through payroll, uses a personal vehicle in the business, or receives below-market rent from a related-party landlord, the valuation analyst will need support for any adjustment. If a one-time technology migration increased expenses, invoices and implementation dates will help separate recurring expense from nonrecurring cost. If a large customer cancelled after the latest financial statement date, the event should be disclosed rather than discovered late in diligence. Late surprises often reduce buyer trust more than the underlying issue itself.
Owner Preparation Before Going to Market
Owners should not wait for a buyer to discover weaknesses in the RMR file. Before marketing the company, management should review inactive accounts, suspended accounts, delinquent balances, expired contracts, duplicate customers, missing assignment provisions, and inconsistent customer names. The goal is not to make aggressive adjustments. The goal is to present the recurring revenue base accurately and consistently. If management believes a delinquent account should remain in RMR because it historically pays late, that belief should be supported by payment history. If management excludes certain low-quality accounts, the exclusion should be documented.
Owners should also prepare a plain-English explanation of the sales model. A security company that grows through builder relationships, referral partners, technicians, online leads, commercial bids, or account acquisitions will have different customer acquisition economics. The appraiser should understand how many leads become proposals, how many proposals become signed contracts, what commissions or equipment subsidies are required, and how quickly new accounts begin paying. Growth is valuable only if the cost of growth is included in the forecast.
Finally, management should identify key employees and operational dependencies. A recurring revenue base may rely on one salesperson, one technician who understands legacy systems, one dispatcher, one central station relationship, or one platform administrator. If those dependencies are not documented, a buyer may assume more transition risk. A professional business appraisal should consider whether cash flow can continue under expected ownership, not merely whether historical revenue existed.
Quality-of-Earnings Questions Specific to RMR Businesses
A buyer may order a quality-of-earnings review in addition to a business valuation. The two processes are different, but they often overlap. Quality-of-earnings work tests whether reported earnings are sustainable and whether revenue recognition, expenses, working capital, and adjustments are reliable. For an RMR business, the review should ask whether active customers are actually being billed, whether revenue is recognized consistently, whether credits and refunds are recorded, whether aging receivables indicate collection problems, and whether deferred revenue or customer deposits have been handled consistently.
The review should also connect sales activity to future service obligations. A company may grow RMR by discounting installation, offering free equipment, or promising service levels that require more technician time than the recurring fee can support. Those choices may be rational, but the economics should be explicit. If the company adds accounts at a loss and recovers the cost over time, the forecast should include the cost of new account generation. If the company has underinvested in vehicles, technicians, or software, normalized cash flow should reflect the investment required to maintain service quality.
These questions are not intended to punish growth. They help distinguish durable, profitable recurring revenue from revenue that looks attractive in a sales deck but requires future spending to keep customers satisfied.

- Installation backlog, project margin history, and open work orders.
- Service ticket history, truck-roll frequency, and technician labor costs.
- Payroll detail, owner compensation, related-party expenses, and benefits.
- Debt schedule, leases, deferred revenue, deposits, and contingent obligations.
- Vehicle, tool, equipment, inventory, and fixed asset listings.
- Customer concentration schedule showing top accounts by RMR and revenue.
- Description of sales channels, lead sources, customer acquisition costs, and commission plans.
- Documentation of any recent acquisitions, account purchases, or major customer losses.
- Management explanation of nonrecurring expenses, unusual events, or accounting changes.
This checklist is not only for the appraiser. It also helps owners identify operational issues before a transaction. If RMR reports do not reconcile, contracts are missing, or attrition categories are unclear, fixing the records before going to market can improve buyer confidence.
Case Study: Two Companies With Identical RMR but Different Values
The following hypothetical example illustrates why RMR alone does not determine value. The companies are fictional and no valuation multiple or conclusion is implied.
| Item | Company A | Company B | Valuation lesson |
|---|---|---|---|
| Reported RMR | Same as Company B | Same as Company A | RMR alone does not decide value |
| RMR records | Monthly roll-forward reconciles to billing and GL | Management spreadsheet does not reconcile to billing | Data quality affects confidence |
| Attrition | Documented and stable | Rising cancellations with weak category detail | Forecast durability differs |
| Account ownership | Clear owned accounts with contracts available | Mix of owned, dealer, and monitored-but-not-owned accounts | Transferability risk differs |
| EBITDA | Healthy normalized margin | Low margin after service costs and platform fees | Cash conversion differs |
| Billing | Automated payments, low delinquency | Manual invoices, high aged receivables | Collection risk differs |
| Customer mix | Diversified residential and small commercial | Few large commercial accounts dominate RMR | Concentration risk differs |
| Technology | Stable platform terms | Migration likely after transaction | Capex and churn risk differ |
| Likely valuation effect | Stronger support for income and market indications | More discounting and scenario analysis | Same RMR can support different values |
Company A gives an appraiser a cleaner basis for the market approach and discounted cash flow. Company B may still have value, but the analysis would likely require more diligence, more conservative assumptions, and potentially less weight on a simple RMR multiple. The example shows why asking “What multiple?” before asking “What quality of RMR?” puts the valuation process in the wrong order.
Security Company Valuation Workflow
This workflow is deliberately sequential. If the account data are weak, later valuation methods become less reliable. If EBITDA is not normalized, market multiples may be distorted. If contracts are not reviewed, transferability risk may be missed. If the report does not reconcile methods, the conclusion may look like a rule of thumb rather than a professional valuation.
Common Mistakes When Using RMR Multiples
Mistake 1: Applying a Generic Multiple Without Source Support
A generic multiple may be easy to quote, but it may not match the subject company, transaction date, account type, included assets, or risk profile. If a multiple cannot be tied to credible comparable evidence, it should not drive the conclusion.
Mistake 2: Ignoring Account Ownership and Assignment Rights
RMR from owned accounts is different from revenue earned by monitoring accounts someone else owns. Contracts, dealer agreements, and assignment rights can materially affect marketability. Legal counsel should review legal enforceability; the appraiser should assess valuation impact.
Mistake 3: Mixing Installation Revenue Into RMR
Installation and project revenue may be valuable, but it should not be treated as monthly recurring revenue unless it is truly recurring and contractually supported. Blending project revenue into RMR can overstate recurring value.
Mistake 4: Comparing Gross Attrition From One Company to Net Attrition From Another
ADT’s public filing shows that attrition definitions can include specific adjustments and exclusions (ADT Inc., 2026). Private companies may define churn differently. Comparing metrics without reviewing formulas is risky.
Mistake 5: Ignoring Dealer Chargebacks, Reinstatements, and Holdbacks
Account purchases and dealer-originated accounts may involve chargebacks, holdbacks, or reinstatement adjustments. These terms can change the economics of acquired RMR and should be reflected in the valuation.
Mistake 6: Valuing Revenue Without Normalizing EBITDA
RMR does not pay the bills by itself. The company must support customers, maintain technology, answer service calls, pay employees, and acquire new accounts. Normalized EBITDA helps determine whether recurring revenue converts into economic benefit.
Mistake 7: Forgetting Debt, Working Capital, Capex, Deferred Revenue, or Deposits
A headline enterprise value does not necessarily equal what equity owners receive. Debt, cash, working capital, deferred revenue, customer deposits, and assumed obligations can change equity value and transaction proceeds.
Mistake 8: Treating Public-Company Filings as Private-Company Transaction Evidence
Public filings are excellent for definitions, risk discussion, and business-model context. They are not automatic valuation comparables for a private local alarm dealer. Size, liquidity, diversification, capital structure, reporting quality, and market access differ.
Mistake 9: Overlooking Platform and Vendor Dependence
Many security businesses rely on central stations, cloud platforms, software vendors, hardware suppliers, and mobile applications. Alarm.com’s filing illustrates the importance of technology-enabled service ecosystems (Alarm.com Holdings, Inc., 2026). A private company should analyze vendor terms, migration risk, and platform costs.
Mistake 10: Failing to Document Assumptions
A business appraisal should document the purpose of the valuation, standard of value, subject interest, methods considered, assumptions, limiting conditions, and evidence used. Professional standards resources emphasize disciplined development and reporting (AICPA, n.d.; IVSC, n.d.; NACVA, n.d.). A conclusion without documentation is hard to defend.
When to Get a Professional Valuation
A professional valuation is useful whenever the value conclusion will affect a transaction, tax position, financing decision, legal matter, or ownership plan. Common situations include buying or selling a security company, partner buyouts, buy-sell agreements, shareholder disputes, divorce, gift and estate planning, lender financing, financial reporting, internal planning, or preparing for investor discussions.
Purpose-Specific Caveat for Legal, Tax, Accounting, and Financing Uses
The intended use should be defined before the valuation work begins. A price estimate prepared for a potential sale may not be appropriate for a divorce matter, shareholder dispute, estate or gift planning project, financial reporting analysis, loan file, or internal planning exercise. Different assignments may require different valuation dates, standards of value, levels of value, report formats, assumptions, and restrictions on use. Professional valuation standards emphasize engagement scope, documentation, method selection, and judgment, which is why the report purpose should not be treated as an afterthought (AICPA, n.d.; IVSC, n.d.; NACVA, n.d.).
For legal, tax, accounting, or financing contexts, the valuation report should coordinate with the client’s attorney, CPA, lender, or other adviser when appropriate. The appraiser can analyze RMR quality, attrition, normalized EBITDA, contracts, and valuation methods, but the appraiser should not provide legal advice about contract enforceability, tax advice about reporting positions, or accounting advice about recognition and measurement requirements outside the valuation engagement. If the matter involves a court order, buy-sell agreement, loan policy, financial reporting standard, or tax filing, those requirements should be identified and supplied to the appraiser at the start. That discipline helps prevent a common problem: reusing a transaction-oriented valuation for a different purpose without checking whether the assumptions and report use still fit.
Simply Business Valuation helps owners, buyers, attorneys, CPAs, lenders, and investors translate RMR, attrition, EBITDA, contract quality, and valuation methods into a documented business appraisal. If you are preparing to sell, buy, finance, or plan around a security or alarm monitoring company, request a valuation before relying on a headline RMR multiple. A professional valuation can identify which value drivers are strong, which assumptions require support, and which risks should be addressed before negotiations.
Frequently Asked Questions
1. What is RMR in an alarm monitoring company?
RMR means recurring monthly revenue. In an alarm monitoring company, it usually refers to recurring fees from monitoring and related recurring services. ADT defines end-of-period RMR for its business as generated by contractual recurring fees for monitoring and other recurring services, including contracts monitored but not owned (ADT Inc., 2026). A private company should define RMR in its own records and reconcile that definition to billing data.
2. Is an RMR multiple the same as a business valuation?
No. An RMR multiple is a market shorthand that may be useful when reliable comparable transaction evidence exists. A business valuation considers RMR, attrition, contracts, EBITDA, cash flow, debt, working capital, assets, liabilities, and risk. A supportable business appraisal should reconcile relevant valuation methods rather than rely on one shortcut.
3. Why can two alarm companies with the same RMR have different values?
They may differ in attrition, account ownership, contract transferability, billing quality, customer concentration, service costs, platform fees, and EBITDA margins. RMR measures recurring revenue, not risk or profitability. The same RMR can produce different cash flow and different valuation conclusions.
4. Should installation revenue be included in RMR?
Usually no, unless a specific portion is truly recurring and billed monthly under a recurring service arrangement. Installation revenue is often project-based and should be analyzed separately. Including one-time installation invoices in RMR can overstate recurring value.
5. What is the difference between account attrition and RMR attrition?
Account attrition measures lost customers or accounts. RMR attrition measures lost recurring dollars. Losing one high-fee commercial account may have a larger RMR impact than losing several low-fee residential accounts. A valuation should consider both when data are available.
6. How many months of RMR history should I prepare before a valuation?
Prepare 24 to 36 months if available. That history helps the appraiser analyze growth, cancellations, price increases, acquisitions, billing corrections, and seasonality. Shorter histories can still be used, but they may require more caution.
7. How does EBITDA affect the value of a monitoring company?
EBITDA shows how much operating earnings the company generates before interest, taxes, depreciation, and amortization. High-quality RMR is more valuable when it converts into normalized EBITDA. If service costs, platform fees, sales costs, or bad debt consume the RMR, value may be lower.
8. When is a discounted cash flow model useful for a security company?
A discounted cash flow model is useful when the appraiser can forecast RMR additions, attrition, price changes, margins, operating expenses, taxes, working capital, capex, and terminal value. It is especially helpful when market transaction data are limited or when company-specific risks need explicit modeling.
9. Does the asset approach matter if the company has strong RMR?
Yes, although it may not be the primary method. The asset approach can identify tangible assets, intangible assets, debt, deferred revenue, deposits, and obligations. It can also serve as a floor or reasonableness check, especially in asset-heavy or low-profit situations.
10. Can public-company filings be used to value a private alarm dealer?
They can be used for definitions, business-model context, risk factors, and industry background, but they should not be treated as direct private-company transaction evidence. Public companies such as ADT, Alarm.com, and Resideo differ from small private dealers in size, diversification, reporting, liquidity, capital structure, and business model (ADT Inc., 2026; Alarm.com Holdings, Inc., 2026; Resideo Technologies, Inc., 2026).
11. What documents should a buyer request before relying on an RMR multiple?
A buyer should request RMR reports, billing exports, customer lists, contracts, cancellation logs, accounts receivable aging, financial statements, tax returns, central station agreements, platform agreements, dealer agreements, account purchase documents, service ticket history, debt schedules, and a customer concentration report.
12. How do monitored-but-not-owned accounts affect value?
They may affect value because the company may not own or freely transfer the customer relationship. ADT’s RMR definition includes contracts monitored but not owned, which shows why the category must be identified (ADT Inc., 2026). In a private transaction, the economic rights and restrictions should be reviewed before applying an RMR multiple.
13. What role do customer contracts and assignment provisions play?
Customer contracts and assignment provisions help determine whether recurring revenue can continue or transfer after a sale. Legal counsel should review enforceability and consent requirements. The appraiser should consider how contract uncertainty affects risk, marketability, and cash-flow assumptions.
14. When should I hire a professional appraiser?
Hire a professional appraiser when value affects a transaction, financing, litigation, tax planning, estate planning, divorce, shareholder matter, or buy-sell agreement. A professional can evaluate RMR, EBITDA, discounted cash flow, market evidence, the asset approach, and documentation requirements in a structured business appraisal.
Conclusion
Recurring monthly revenue is one of the most important value drivers in many security and alarm monitoring companies, but it is not the whole valuation. A supportable conclusion requires more than a headline RMR multiple. It requires a clear RMR definition, a monthly roll-forward, attrition analysis, account ownership review, contract and billing diligence, revenue segmentation, normalized EBITDA, cash-flow forecasting, balance sheet analysis, and method reconciliation.
The strongest valuations connect recurring revenue to expected future cash flow and risk. The market approach may include RMR or EBITDA evidence when comparable transactions are reliable. The discounted cash flow method can model how RMR grows, churns, and converts into cash. The asset approach can identify tangible and intangible assets and liabilities. A well-supported business appraisal explains why each method was used, how assumptions were selected, and how the final conclusion was reconciled.
If you are evaluating a security or alarm monitoring company, do not rely on an unsupported RMR multiple. Use RMR as the starting point, then test the quality of the revenue and the economics behind it. Simply Business Valuation can help you turn those facts into a documented, decision-ready valuation.
