How Attrition Quietly Reprices a Life Safety Acquisition

Key Takeaways

• Attrition above 10% annually can shrink a life safety company’s effective sale multiple by 20% or more once diligence begins, making it the single most common source of post-LOI price adjustments.
• A business valuation consultant who works in the security and Personal Emergency Response Systems (PERS) space will separate contractual Recurring Monthly Revenue (RMR) from non-contracted recurring services before a buyer ever builds a pricing model.
• Holdback disputes after closing often trace directly to attrition patterns that were visible in the account data months before the letter of intent was signed.
• Buyers and PE firms entering life safety should request 36 months of gross and net attrition data, segmented by account type, revenue tier, and contract status, before making an offer.
• TRG Associates has studied attrition behavior across the life safety industry for 25 years, providing its valuation work with a dataset that reflects how real portfolios perform over time.

A security company owner receives an LOI at 38x RMR, and the number feels right. Six weeks into due diligence, the buyer’s team pulls three years of account-level data and finds net attrition exceeding 13% annually, and the offer is recalculated to 30x. The deal still closes, but the owner leaves several hundred thousand dollars behind because a single metric, one that a business valuation consultant would have flagged weeks earlier, went unreviewed before the company went to market.

This pattern appears regularly in life safety M&A, and the mechanism is predictable once you have watched it play out across enough transactions. Attrition tells a buyer how durable the revenue stream is, and any business valuation and financial due diligence process that skips the account-level view will miss the signals that reprice a deal.

If your RMR has never been stress-tested by someone who works full-time in life safety transactions, that conversation is worth having before you reach the LOI stage. Book a call with TRG Associates.

RMR Quality Sits at the Center of Every Life Safety Valuation

Recurring monthly revenue (RMR) is the core asset in any security, fire, or PERS transaction, and buyers pay a multiple of that stream, which means the quality of each dollar matters as much as the total. The SDM 100 report has ranked the industry’s largest dealers by RMR since 1991, and for good reason: in life safety, RMR is the language of valuation.

When a business valuation consultant evaluates an RMR portfolio, the first question is whether the revenue is contractually bound or month-to-month, because those two categories carry very different risk profiles for a buyer inheriting the book.

Non-contracted recurring services, meaning accounts with verbal agreements or missing contracts, will reprice a deal faster than almost any other diligence finding. A $5 million RMR portfolio with 30% of its accounts without contracts tells a buyer that nearly a third of the revenue could leave on 30 days’ notice, and TRG Associates regularly sees this gap as the single largest point of renegotiation in a life safety transaction.

What 36 Months of Account Data Shows a Buyer

Gross attrition measures how many accounts cancel over a given period, while net attrition accounts for new additions. A buyer’s diligence team will examine both and will want at least 36 months of history, because a 12-month snapshot can mask seasonal patterns, retention campaigns, and accounts temporarily saved through discounting, and three full years are needed to reveal the real trendline.

Within that data, company valuation consultants working in life safety will segment attrition by account type. Commercial accounts, residential monitored accounts, and PERS subscribers each behave differently: commercial accounts tend to churn less frequently but represent larger per-account revenue losses when they cancel. In contrast, PERS subscribers may show higher gross attrition due to the demographic profile of the population they serve.

TRG Associates has run its annual attrition study for 25 years alongside The Monitoring Association, which gives us a real baseline for what healthy attrition looks like by segment and company size. When a seller’s numbers sit well above that baseline, a buyer’s diligence team will use the gap to reprice the offer.

Holdback Disputes That Start Before the Closing

Most life safety acquisitions include a holdback, a portion of the purchase price placed in escrow for 12 to 24 months to confirm that the acquired accounts actually stay. If attrition during the holdback period exceeds the threshold in the purchase agreement, the seller receives less money, and these disputes are among the most common reasons TRG Associates provides expert witness support in the industry.

The pattern that leads to holdback disputes almost always begins before the deal closes. Owners who have never tracked attrition at the account level cannot accurately represent what the buyer is inheriting, and buyers who rely on summary-level attrition numbers from internal reports miss the granular signals that predict post-close churn. Contract assignability is one of those signals: if a large portion of subscriber contracts lacks clear assignment language, the buyer may face customer cancellations as customers treat the ownership change as their exit opportunity.

Why This Gets Missed Without an Industry Specialist

A generalist M&A advisory shop conducting business valuation and financial due diligence will apply standard revenue-quality frameworks, including churn rates, customer concentration, and contract terms. The industry-specific context that makes those numbers meaningful in life safety requires years of working inside the space.

Consider a PERS company showing 18% annual attrition. Measured against a SaaS benchmark, that figure looks alarming, but within the PERS segment, where subscribers age out of the service or pass away, the picture changes. Security Sales & Integration reports that PERS attrition typically runs 25% to 30% annually due to the demographics of the elderly population, which means 18% may actually reflect a healthier book than a buyer’s generalist framework would suggest.

The real question for a buyer is whether the company’s gross add rate can sustain growth against that natural attrition, and answering it requires comparison data from actual PERS portfolios. TRG Associates brings 25 years of benchmarking data to that analysis, grounded in real transaction experience across hundreds of engagements.

Where to Start This Week

• Pull 36 months of gross and net attrition data, segmented by account type: commercial, residential, and PERS.
• Identify the percentage of your non-contracted RMR or sitting on contracts without industry-standard terms. 
• Review your subscriber contracts for assignment language that would survive an ownership change, and note any accounts where assignment provisions are absent.
• Compare your attrition rates with published industry benchmarks to see how your portfolio compares with the broader market.
• If you are considering a sale or acquisition in the next 12 to 18 months, engage a business valuation consultant who specializes in life safety before reaching the LOI stage, because the cost of discovering an attrition problem in diligence is almost always higher than the cost of addressing it beforehand.

The Bottom Line

Attrition is the number that represents more life safety deals than any other single finding in due diligence. The gap between what an owner believes their RMR is worth and what the account-level data shows a buyer is often the largest source of renegotiation after the LOI, and it is almost always a gap that could have been closed before going to market with the right preparation and the right business valuation consultant in the room. TRG Associates provides valuation and financial due diligence to security, fire, and PERS companies, backed by 25 years of published attrition benchmarking data.

Frequently Asked Questions

What is RMR attrition and why does it affect a security company’s sale price?

RMR attrition measures the rate at which subscribers cancel their monitoring or service contracts over a given period. In a security or life-safety company sale, the buyer is purchasing a stream of recurring monthly revenue, and attrition indicates how quickly that stream erodes. Higher attrition means the buyer inherits a less durable revenue base, which directly reduces the multiple they are willing to pay.

How does a business valuation consultant assess RMR quality in a life safety company?

A business valuation consultant working in life safety will segment the RMR portfolio by contract status, account type, and revenue tier. They examine whether accounts are contracted, how attrition rates compare with industry benchmarks, and whether subscriber contracts contain assignability clauses that protect revenue during an ownership transition. This segmented view is what allows the consultant to identify issues before a buyer does.

What is a holdback in a security company acquisition?

A holdback is a portion of the purchase price placed in escrow after closing, typically for 12 to 24 months. The holdback confirms that the acquired subscriber accounts remain active during the transition period. If attrition during the holdback exceeds a contractually defined threshold, the seller receives a reduced payout, which is one of the most common sources of post-transaction disputes in the life safety industry.

How far back should attrition data go before listing a life safety business for sale?

Buyers and their diligence teams will typically request at least 36 months of gross and net attrition history. A 12-month window can mask seasonal fluctuations, one-time retention campaigns, or accounts temporarily saved through discounting. Three years of data shows the real trendline and gives a business valuation consultant enough history to benchmark the company against industry norms, which is why preparing this data before going to market makes the entire transaction run more smoothly.
