Every contractor knows the grit it takes to scale a specialty construction, MEP (Mechanical, Electrical, Plumbing), or infrastructure firm to a position of market leadership. However, when the time comes to transition from building the business to capitalizing on its value, many owners discover operational success doesn’t automatically translate into transaction success.
Buyers view construction firms through a hypercritical lens. They don’t just buy your past revenue or your current list of contracts; they buy the predictability of your future cash flows and the institutional controls guarding your profit margins. If your internal systems cannot transparently defend those margins, a buyer will look for margin slippage, price in the operational risk, and discount your valuation accordingly.
To explore how middle-market specialty contractors can successfully protect record multiples during a sale, Samantha Jones, Principal at Walden M&A, and Josh Roper, “The Construction CFO” and founder of Verity Financial Consulting, a premier construction CFO advisory practice, share their thoughts. Together, they lay out the financial, compliance, and strategic playbook required to turn operational momentum into premium market value.
The Monthly WIP Standard: Eliminating Buyer Skepticism
A healthy backlog is the lifeblood of an infrastructure or MEP business, but an unverified backlog is a liability in a transaction. Many closely held construction firms operate under a lagging financial model, updating their Work-in-Progress (WIP) schedules strictly at period-end or year-end. While this may suffice for annual tax reporting, it is a glaring red flag for institutional buyers.
“If a buyer notices you only update your WIP at period-end, they immediately grow skeptical of the quality of your financials,” notes Jones. “It signals you lack the real-time metrics and dashboards to manage the business on an ongoing basis. They will instantly look for margin slippage”.
Jones recalls a specific transaction where a seller presented a backlog clearly dated with projects from the prior year, yet the WIP data failed to reflect the current operational status. The buyer immediately questioned whether critical projects had slipped or stalled. Even though the operational reality was sound, a kernel of doubt had been planted in the buyer’s mind. In M&A, doubt costs money.
Transitioning away from this systemic vulnerability requires rigorous, percentage-of-completion monthly accounting controls. “The WIP schedule shouldn’t just be an accounting exercise; it is the owner’s absolute best one-page snapshot of company performance,” says Roper.
To institutionalize this before a sale, Roper advises establishing a strict monthly close cadence that bridges the gap between the field and the finance department.
“For my clients, we meet once a month, pulling all the project managers into a conference room and going through each of their jobs in a very detailed fashion on a cost code by cost code line item,” Roper explains. “And then we look at are they properly billed? Are they properly collected? Are they on schedule for performance and production?”
When a buyer reviews historical financials and sees years of disciplined, monthly WIP data backed by rigorous operations meetings, their perceived risk drops. You are no longer just a contractor hoping for a good year; you are an enterprise running a highly predictable, tightly controlled financial engine.
De-Risking the Backlog: Fixed-Price vs. Cost-Plus Value
The composition of your contract mix heavily dictates how buyers calculate your risk profile. While Cost-Plus arrangements provide safe, predictable parameters, specialty contractors frequently rely on Fixed-Price contracts to win competitive bids and capture higher upside. The downside? Institutional buyers view a heavy concentration of Fixed-Price contracts as an unhedged bet against inflation, labor shortages, and supply chain volatility.
Defending a premium valuation means proving to an acquirer your estimation processes are bulletproof and your Fixed-Price margins are structurally insulated.

Roper highlights that top-tier firms protect these margins by explicitly tracking three distinct phases of a project’s financial lifecycle.
“Everybody thinks there’s only one estimate to a project. There’s not. There’s three estimates,” he notes. After the initial bid estimate, firms must create a revised budgeted estimate immediately following the project buyout. Finally, there is the true estimate which equals the costs incurred to date, plus the costs to complete the project.
“On a monthly basis, they’re re-forecasting the entire project as if they were reestimating the job today to see what it would take to complete it as of today,” Roper explains. “If a project manager’s margin changed by $5,000, you should be able to tell us why. Did we estimate something wrong or did we execute something poorly, or was something done out of scope indicating a potential opportunity for a change order?”
If you catch margin fade in month two of a ten-month job, you can correct the course. If you wait until the project is over to calculate profitability, you aren’t managing a business—you are performing a financial autopsy. Showing a buyer a historical track record of consistent project re-forecasting proves you can successfully manage risk under any contract structure.
Aligning the Project Portfolio
Transitioning from risk mitigation to portfolio strategy, Jones points out that not all backlogs are valued equally.
“It’s the mix of projects that are so important right now,” she observes, noting that a company’s end-market focus directly influences its capitalization multiple. “If you are someone who is solely focused on residential, you might be in a tough situation. You want to make sure you’re balancing out mix, specifically commercial, which means these days, you’re likely talking about data centers”.
The explosive buildout of digital infrastructure means strategic and financial buyers are aggressively paying premiums for contractors holding master service agreements (MSAs) with technology giants and enterprise data center developers. However, scaling into these elite tiers requires capital and capacity thresholds many mid-market firms fail to anticipate.
Roper agrees with Jones’s assessment, adding that while scaling into high-growth sectors like data centers is highly profitable, it requires an intimate understanding of credit metrics, working capital thresholds, and surety bonding capacity. He notes that a contractor’s bonding capacity for a single job is generally capped at 10 times their working capital, meaning massive commercial bids require significant cash on the balance sheet.
To secure the bonding necessary for these lucrative projects, contractors must plan ahead. “You have to find a right balance of an inverse relationship between financial reporting and income tax reporting where we want to minimize the income tax effects… but maximize our credit capacity,” Roper states. If an owner strips too much cash out of the corporate entity to avoid taxes or fund personal lifestyles, they unintentionally hinder the company’s bonding capacity—preventing them from winning premium projects and suppressing the firm’s ultimate transaction value.
Labor Audits: Overtime and Compliance Due Diligence
Specialty construction is fundamentally a labor-driven industry. Consequently, a buyer’s legal and financial due diligence teams will mercilessly stress-test your historical labor practices.
Jones explains exactly why this is such a critical vulnerability during the M&A process: “There is extra level scrutiny around I-9s at this point, and if they’re not up to date and accurate, you will not only not be able to bid on federal projects, you will take a discount from a buyer”.
She further warns about the severe dangers of sloppy payroll tracking. “Tracking of overtime and making sure that you’ve done this correctly to the letter of law… if you haven’t, there is a potential liability for a buyer that they’re going to be paying back taxes for issues, and it won’t matter that they didn’t own the company at that point in time,” Jones adds.
To ensure a seamless, clean transaction, sellers must proactively audit their internal payroll controls and field labor records months before going to market.
Roper points out a sophisticated buyer will pull comprehensive transcripts directly from the IRS to audit the timeliness, accuracy, and compliance of your historical filings. They will meticulously audit multi-state processing tracks. Many regional contractors mistakenly report payroll solely out of their home state, ignoring the fact that if field personnel are stationed on an out-of-state infrastructure build for an extended period, payroll taxes must be remitted to the specific state.
Catching and correcting these cross-border tax issues and strengthening internal Section 125 compliance beforehand eliminates the leverage buyers use to chip away at your valuation.
Normalizing Earnings for a Premium Sale
Evaluating historical cash flow represents a critical step for prospective acquirers assessing a business. Founder-owned firms frequently process operational expenses serving a dual purpose—supporting both daily business activities and owner-specific requirements. While entirely standard for privately held enterprises, institutional buyers focus strictly on the unencumbered cash flow the company will generate moving forward. Normalizing the income statement illuminates true operational profitability, allowing owners to capture maximum value during a transaction.
Balancing working capital requirements with profit distributions requires strategic intent as an owner approaches a sale. Josh Roper advises privately held business owners to manage distributions carefully, avoiding conflicts with bank line covenants or bonding constraints. Incoming institutional buyers evaluate underlying asset quality, meaning excess cash typically leaves the business prior to closing.
The primary financial focus ahead of a sale centers on normalizing the corporate income statement to reveal true adjusted EBITDA. Roper highlights a seller attempting to route family salaries through corporate operations to minimize annual income taxes. “If you are preparing to sell your MEP firm at a premium 6x or 8x multiple, saving $25,000 in income tax by keeping a non-operational relative on the payroll could inadvertently wipe out $150,000 to $200,000 in enterprise transaction value,” he explains. Removing personal or non-operational expenses from corporate payroll directly increases final transaction value.
In the 18 to 24 months leading up to an exit, work with your advisors to normalize your income statements. Clean up discretionary spending, adjust owner compensation to true market rates, and let the authentic profitability of your specialty construction firm flow cleanly to the bottom line.
Transitioning from Operator to Enterprise
When you prepare to sell a specialty construction or MEP business, you are no longer selling your personal ability to manage a complex job site or hustle for the next bid. You are selling the institutional systems that guarantee future profitability. Buyers pay premium multiples for predictability, not owner-dependence.
By standardizing monthly WIP closes, perfecting contract margin defense, maintaining pristine labor compliance, and normalizing balance sheet equity, you transition your company from a founder-reliant operation into a highly prized, risk-mitigated enterprise. You eliminate the kernels of doubt buyers use to justify steep valuation discounts.
