Why a wire harness or cable assembly company must be ready before it goes to market and what HarnessPoint™ uncovers before the buyer does
Alex spent twenty-three years building Crimp & Poke Assembly Solutions from a single leased bay with two crimp presses and one industrial customer into an $18 million wire harness and cable assembly shop. By the time he was ready to sell, the business ran a 16% EBITDA margin, just under $2.9 million a year, on a reputation his customers trusted and a crew that had been with him for most of two decades. He did everything a disciplined founder is told to do. He cleaned up his books, hired a sell-side advisor, and signed a letter of intent at an enterprise value of $21 million.
Then the deal went to diligence.
Over the next ten weeks, the buyer’s financial due diligence team sat with his model, his customer file, and his inventory, and they walked back out with a different set of numbers. Alex still closed. But he closed at roughly $16.5 million, about $4.5 million, better than a fifth of the price, gone, on facts that had been true for years and that nobody had pressure-tested until a buyer did it for him. The working-capital settlement then trimmed the cash a little further still.
None of it was fraud. None of it was even a surprise, once you knew where to look. It was the predictable cost of going to market before the business was ready for a sale. Crimp & Poke is a composite, a stand-in for a pattern we watch repeat across this industry, but the numbers below are not invented for effect. Each one maps to something real, and each one is something that a proper exit-readiness review surfaces first, while the founder still has the time and the leverage to do something about it.
A clean set of reviewed financials tells a buyer your numbers are accurate. It says nothing about whether they survive someone with a checkbook challenging them line by line.
01 | The Add-Backs That Don’t Survive
“Quality of Earnings” (QoE) is the review a buyer commissions from its own accountants or a third-party firm in the weeks between the letter of intent and the close. It is not a re-audit. It exists to test one question: when we price this company on its adjusted EBITDA, do those adjustments hold up when we challenge them one at a time? In the lower middle market, the place they stop holding up is almost always the same. The add-backs.
Alex’s model walked from a reported EBITDA of $2.88 million, that clean 16%, up to an adjusted figure of $3.5 million. $620k of add-backs. At the 6.0x multiple his sell-side advisor was marketing, that bridge alone was worth nearly $3.7 million of enterprise value, so every line in it was worth defending. The buyer challenged every line. They sort into a few familiar buckets, and a buyer works each one the same way.
The one-timers that weren’t. The “one-time” tooling write-off booked last year turned up again, in a slightly different costume, the year before that, and the year before that. Premium freight logged as a “non-recurring launch expense” on a shop that launches something new every year. Roughly $170,000 of the add-backs lived here, and a buyer strikes anything that recurs, no matter what it is called. To be fair, not every one-timer is a fiction: a genuine ERP conversion and a settled lawsuit, about $210,000 together, were exactly the kind of clean, dated, never-again events a buyer will credit. Those survived. The recurring ones did not.
Owner costs dressed as company costs. The truck, the club membership, the personal travel run through the business, about $130k, and on those, a buyer will usually give the seller the benefit of the doubt, because they genuinely leave when he does. The harder line was the $110k paid to Alex’s spouse as “VP of Culture.” A real person, but not a seat the buyer would ever need to fill, which is precisely why a buyer will not pay for it.
Off-market and related-party positions. Alex paid himself a modest salary and took the rest in distributions; the buyer normalized his pay up to what it would cost to hire a plant manager, and EBITDA came down about $120k. The building sat in his real-estate LLC and was rented to the company at below-market rent; the buyer marked the rent to market, and the cost rose by about $60k. The overmold and potting work routed to a shop his brother-in-law owns was priced as a favor; re-priced to a market rate, that was another $40k.
Put it together and the picture is unforgiving. Of the $620k in add-backs, the buyer absorbed about $340,000 and wrote off the other $280,000. Then it layered on $220,000 of its own downward normalizations for owner pay, rent, and related-party pricing. The $3.5 million adjusted figure Alex had built his price on settled at $3.0 million in the buyer’s model, and not a dollar of revenue or working capital had been touched yet.
02 | Quality of Revenue: Concentration, Contracts, and the PO Reality
If the add-backs are where a founder loses the argument, revenue quality is where he loses the most money, because it hits the multiple, not just the number the multiple is applied to. Almost none of it shows up on the P&L. All of it reads off the customer file in an afternoon, and all of it lands in the buyer’s report two weeks after the seller assumed the price was settled.
Concentration. Crimp & Poke’s largest account, an off-highway OEM, was 38% of revenue, just under $7 million riding on one customer’s release schedule. The top three together were 65%. A buyer prices single-customer exposure as risk and takes it straight out of the multiple.
The purchase-order reality. The backlog looked reassuring, several million dollars in open releases. But those were blanket purchase orders against non-binding forecasts, not contracts. There was nothing the customer was obligated to buy, and a buyer’s discount backlog cannot be enforced. Most lower-middle-market harness backlog cannot be enforced.
The stickiness myth. Alex believed his programs were sticky because re-validating a harness is slow and expensive. He was half right. The pain was real, but the customer owned the tooling and held the prints. The switching cost was theirs to spend, not his to bank.
Churn hiding inside an average. His blended retention number looked healthy. Underneath it, two programs were at end-of-life, and a third was already being dual-sourced to a plant in Mexico. A buyer builds revenue forward off the programs that will survive, not the average that hides the ones that won’t.
Compliance-dependent revenue. A meaningful slice of the work was in defense and aerospace, carrying AS9100 today and facing CMMC obligations fast approaching. Revenue that requires continued investment to keep gets discounted by the buyer, who now has to make that investment.
None of these is fatal on its own. Stacked together, they did what concentration and soft contracts always do, they took roughly half a turn off the multiple, from the 6.0x in the marketing book to 5.5x in the buyers. On $3.0 million of adjusted EBITDA, that half-turn is $1.5 million. The revenue never fell. The price the market would pay for it did.
03 | Working Capital: The Peg That Eats the Premium
Working capital is the quietest line in a deal and routinely the most expensive. A wire harness shop is working-capital heavy by its nature, wire, cable, connectors, terminals, contacts, long-lead components, and the safety stock a demanding OEM expects you to carry on its behalf.
Alex’s model pegged net working capital at a trailing twelve-month average, a number that looks perfectly reasonable on a Friday afternoon. The buyer pegged it differently, the way buyers always do. They stripped out receivable terms that had been one-time accommodations to a single customer. They excluded supplier financing Alex had folded into ordinary operations. They rebuilt the peg month by month to reflect seasonality, because closing dates rarely land on the convenient average point of the cycle. And they wrote down the slow-moving and obsolete inventory still sitting on the floor from the two dead programs: wire, cable, and connectors bought for demand that no longer existed.
The gap between his peg and theirs was close to 275k, and it came straight out of the cash that crossed the table at close. Working capital almost never moves the multiple. It quietly moves the money you take home.
04 | The EBITDA Bridge: Where It All Converges
Everything converges in one document: the EBITDA bridge. The bridge shows how reported EBITDA in the reviewed accounts becomes the adjusted EBITDA on which the price is built. Every line, every add-back, every revenue-quality adjustment, every reclassification has to reconcile to a specific number in the financial statements.
When a bridge fails to reconcile in even a handful of places, a buyer does not simply discount those places. It concludes the rest is just as soft, and it re-prices the whole deal. Not the lines that broke, but the price.
Alex’s bridge broke in a few spots: the recurring “one-timers,” the spouse’s role, the under-market rent. That was enough. The buyer’s confidence in the entire adjusted number eroded, the multiple came in, the peg moved, and a $21 million letter of intent became a $16.5 million re-trade.
Here is the part many founders miss. Almost no lower-middle-market model survives this on the first pass, because almost no one builds it to. The model exists to support the marketing story. Nobody builds the parallel layer that anticipates the buyer’s (QoE), whose entire job is to take that story apart, one line at a time.
The buyer didn’t find anything that wasn’t already there. He simply found it first. Exit readiness is the discipline of finding it before he does.
05 | What HarnessPoint Finds First
This is the exact gap HarnessPoint™ was built to fix. HarnessPoint is Blue Valley Capital’s exit-readiness program, a structured review run 12 to 24 months ahead of a sale, designed by people who have built and sold wire harness companies, around a single principle: build the buyer’s Quality of Earnings before the buyer can.
Run on Crimp & Poke a year earlier, the same review that cost Alex $4.5 million in diligence becomes a punch list, while he still has the runway to work it:
— The recurring “one-time” costs are documented and removed from the add-back story, so nothing in the bridge is wearing a costume.
— Owner compensation normalized to a market salary on paper, the related-party lease re-papered at market rent, and the brother-in-law’s overmold work re-priced, so there is nothing left for a buyer to mark.
— Customer concentration is quantified honestly, with a real campaign underway to convert blanket POs into firmer agreements and to win back program share before the business ever goes to market.
— Slow-moving and obsolete inventory is scrapped, reserved, or sold, so it is not a write-down lying in wait inside the working-capital peg.
— A defensible, month-by-month net working capital analysis, so the seller sets the peg conversation instead of receiving it.
— AS9100 and CMMC gaps closed, turning at-risk defense revenue into revenue a buyer will pay full value for.
— An EBITDA bridge that reconciles to the financials on the first pass, because it was built alongside the marketing model, not bolted on afterward.
HarnessPoint runs in phases. The first is a diagnostic and a red-item action report: the same findings a buyer’s (QofE) would surface, handed to the founder while there is still time to act on them. The phases that follow are the fixing. By the time the company goes to market, the story and the numbers tell one version of events, leaving nothing on the table for a buyer to take.
Alex didn’t lose that $4.5 million at the closing table. He lost it in the year and a half he never spent getting ready for it, time he had and didn’t use. If you are twelve to twenty-four months from a sale, or you suspect you might be, that is the window this work is built for. A buyer will find everything in this article. The only question that decides what it costs you is whether you find it first.
