How to Value a Cable & Internet Installation Contractor in 2026

Cable and internet installation contractors are one of the most misunderstood categories in the M&A market. From the outside they look like commodity labor shops — a truck, a ladder, and a guy with a crimper. In reality, the good ones are relationship businesses built on decade-long master service agreements with Comcast, Charter, Altice, and the regional ILECs. Those relationships are the entire asset, and they don't transfer automatically.

I've watched sellers walk into a sale thinking they had a $15M business and walk out with $6M because they couldn't prove their MSA with Charter would survive a change of control. Let me walk you through how these businesses actually trade.

Who Buys Cable Installation Contractors

There are three distinct buyer pools, and each values the business differently.

Strategic consolidators like Dycom Industries, MasTec, and Quanta Services are the biggest checks in the market. They roll up regional installation contractors to build national footprints that Comcast and Charter can contract with in a single MSA. These buyers pay 5.5-7.0x trailing EBITDA for businesses doing $10M+ in revenue with clean MSA coverage and a demonstrated safety record.

Private equity platforms — firms like Tower Arch, Huron Capital, and CIVC Partners have been building telecom services platforms for years. They'll pay 5-6x EBITDA for platform acquisitions and 4-5x EBITDA for bolt-ons into an existing portfolio company. The PE discount reflects the fact that they're going to need to professionalize your back office before they can resell you to a strategic.

Regional operators and owner-operators buy the smaller shops — under $3M EBITDA — usually with SBA financing. They pay 3.5-4.5x EBITDA or 2.0-3.0x SDE depending on how much of the business runs through the owner personally.

The MSA Is the Whole Ballgame

Here's the thing no first-time seller understands: your Master Service Agreement with Comcast or Charter is almost certainly not assignable without written consent. I've read dozens of these contracts and they all contain language that effectively says "if you sell your company, we can terminate." That clause alone is why diligence on these deals takes 90-120 days instead of 45.

Buyers will want to see three things before they put down real money. First, the MSA itself — how long is the term, what are the renewal provisions, and what's the termination-for-convenience clause look like? Second, your scorecard with the ISP — Comcast rates contractors on quality, timeliness, and safety, and a declining scorecard is a screaming red flag. Third, some form of pre-close comfort from the ISP that they won't terminate at close. Sophisticated buyers will literally refuse to sign until they've had a call with the ISP's contractor management team.

If your contractor scorecard with Charter is declining, fix it before you go to market. Every point you lose on your quality score costs you 0.5x on your multiple.

Customer Concentration and the Comcast Problem

Most cable installation contractors are essentially single-customer businesses. 80% of revenue from Comcast isn't unusual — it's the norm. Buyers know this and they've stopped pretending it's a dealbreaker, but they do price it in aggressively.

A business with 90%+ revenue from a single ISP will trade at the low end of the range — call it 4.0-4.5x EBITDA — even if everything else is pristine. A business with exposure to two or three ISPs (say, 50% Comcast, 30% Charter, 20% a regional fiber overbuilder like Ziply or Brightspeed) can push into the 6x range. I've seen one contractor with balanced Comcast, Charter, Frontier, and AT&T exposure get 7.2x from MasTec because the buyer was essentially paying for diversification they couldn't replicate organically.

The lesson: if you're 2-3 years from a sale and you're 90% Comcast, start bidding on Charter work now. Even unprofitable diversification revenue creates optionality that buyers will pay for.

The Workforce Question

The second biggest diligence item after the MSA is your technician workforce. Cable installation has been in a labor crisis since 2021 and it hasn't gotten better. A trained, BICSI-certified installer with three years of experience and a clean driving record is worth $85-110K fully loaded in most markets, and the ISPs require contractors to carry specific certifications before techs can touch their plant.

Buyers will ask for a headcount roster showing tenure, certifications, DOT status, and W-2 versus 1099 classification. This last point matters enormously. A lot of installation contractors have been running hybrid workforces where the company owner treats clearly misclassified workers as 1099 subcontractors to save payroll tax. The DOL has been aggressive about this since 2023, and any buyer's diligence team will flag it. I've seen deals where the 1099 exposure was large enough to knock 1-2x off the multiple or force a material escrow. If you're running a heavy 1099 model, talk to an employment lawyer now, not later.

Retention matters too. A business where the average tech has been there four years looks very different from one where the average tenure is ten months. Buyers assume they're going to lose 15-25% of techs in the year after close, and they adjust their EBITDA accordingly.

Normalizing EBITDA for These Businesses

Cable contractors tend to run dirty books. It's partly a culture thing and partly because the work is famously lumpy — a single storm restoration job can swing quarterly EBITDA by 20%. Normalizing correctly is the difference between a fair deal and getting skinned.

The adjustments I see most often include owner compensation above market (usually $250-400K that needs to be normalized down to $180-220K for a replacement GM), owner vehicles and personal fuel, one-time MSA bid costs, storm restoration windfall revenue that shouldn't be baked into run-rate, and workers comp experience mods that are about to reset. On the other side, make sure you're capitalizing truck purchases properly instead of expensing them — buyers will respect clean capex accounting.

A proper quality of earnings report costs $40-75K for a business this size and it pays for itself five times over. Read our guide on SDE versus EBITDA to understand which metric the buyer pool will actually use on your business.

What Kills Value in This Industry

Safety incidents. Your EMR (experience modification rate) on workers comp is a public number, and your OSHA 300 log tells a story. A contractor with an EMR above 1.1 or a recent recordable is going to get marked down by every serious buyer. The ISPs are aggressive about dropping contractors with poor safety records, so buyers view bad safety as an existential risk to the MSA.

Scorecard decline. I mentioned this above but it bears repeating. Your quarterly scorecard with Comcast or Charter is the single best predictor of whether your MSA will renew. A trend line going the wrong way will cost you a full turn of EBITDA.

Aging fleet. Bucket trucks and splice trailers are expensive, and a fleet with an average age above 8 years tells the buyer they're about to inherit $500K-$2M of deferred capex. Replace the worst units before you go to market.

No recurring MSA revenue. Contractors who only do new-build projects are worth meaningfully less than those with recurring T&M (time and materials) maintenance contracts. Maintenance work is predictable, higher margin, and sticky through ISP consolidation.

How to Maximize Your Sale Price

If you're 18-24 months from sale, here's what moves the needle. Get your scorecard with every ISP to the top quartile. Diversify so no single customer is above 65% of revenue. Convert your 1099s to W-2 and eat the margin hit — buyers will pay you back with a higher multiple. Get a 3-year lease on your yard with a renewal option so the buyer has certainty. Build an operations bench so the business isn't dependent on you personally managing dispatch.

Most importantly, get a signed renewal or extension on your MSA before you go to market. A contractor going to market in year three of a five-year MSA is worth meaningfully more than one going to market in year five. See our playbook on preparing your business for sale for a full 18-month timeline.

The Bottom Line

Cable and internet installation contractors trade in a 4-7x EBITDA range, with the difference between a 4 and a 7 driven almost entirely by three things: MSA quality and term, customer diversification, and workforce classification. Sellers who fix those issues 18 months before going to market routinely get 40-60% higher valuations than those who go to market with problems visible on day one of diligence. The buyers in this space — Dycom, MasTec, Quanta, and the PE platforms behind them — have seen everything, and they pay for clean businesses.
