Revenue Looks Strong on Paper – But ASC 606 Compliance in Construction Tells a Different Story

Revenue Looks Strong on Paper – But ASC 606 Compliance in Construction Tells a Different Story

Revenue looks strong on paper – but ASC 606 compliance in construction tells a different story. In this case study, The McLean Group’s Financial Consulting and Transaction Due Diligence teams walk through a real construction services engagement where a project-level ASC 606 review surfaced a pattern of revenue recognition issues that materially changed the earnings picture. We examine the KPIs that matter most, including cost-to-complete accuracy, change order approval rates, and over and under billing trends, and explain why ASC 606 compliance deserves the same rigor in diligence as working capital analysis or debt-like items.

Purchase Price Allocations Under ASC 805: What Every PE-Backed CFO and Deal Team Needs to Know

Purchase Price Allocations Under ASC 805: What Every PE-Backed CFO and Deal Team Needs to Know

A purchase price allocation (PPA) is the first post-close workstream that directly affects reported EBITDA, lender covenant calculations, and eventual exit valuation for PE-backed acquirers. Under ASC 805, every acquisition requires the buyer to allocate the total purchase price to identifiable assets and liabilities at fair value — including intangibles that never appeared on the target’s balance sheet. For middle-market deals, identified intangibles commonly represent 30–60% of total consideration, and each carries its own valuation methodology, useful life assumption, and amortization consequence. The McLean Group’s Valuation Advisory team breaks down what every CFO, controller, and deal team needs to know about getting the allocation right the first time. […]

What Is a 409A Valuation and When Does Your Company Need One?

What Is a 409A Valuation and When Does Your Company Need One?

A 409A valuation is an independent appraisal of your private company’s common stock, and if you’re issuing equity incentive awards to employees, it’s a legal requirement, not a formality. Get it wrong, and employees face immediate income recognition, a 20% federal penalty tax, and potential state penalties that can push effective tax rates well above 50%. In this article, The McLean Group’s Valuation Advisory team breaks down exactly how 409A valuations work, when your company needs one, which IRS safe harbor methods apply at each stage, and the common mistakes that create tax exposure at exactly the wrong time: during fundraising, M&A due diligence, or an IRS audit.

EBITDA Only Tells Part of the Story. Does Your QofE Provider Reveal the Rest?

EBITDA Only Tells Part of the Story. Does Your QofE Provider Reveal the Rest?

Normalized EBITDA shows clean profitability, but it doesn’t tell you whether that profitability is built to last. For PE sponsors, the difference between a well-priced deal and a costly mistake often comes down to whether your Quality of Earnings provider goes beyond standard adjustments and into the operational KPIs that reveal true margin durability. The McLean Group’s Transaction Advisory team explores how the right diligence partner layers in gross margin by service type, resource utilization rates, and backlog conversion patterns to give buyers a sharper view of risk, a stronger basis for negotiation, and a head start on post-close execution.

The Water Sector’s Biggest M&A Moves of 2025

The Water Sector’s Biggest M&A Moves of 2025

The McLean Group’s Water, Wastewater, and Environmental Industry: 2025 in Review & 2026 Outlook examines another active year for water sector M&A, with 159 transactions closed across water utilities, treatment solutions, components, and services. Despite broader market volatility driven by tariff uncertainty and rising input costs, strategic and financial buyers remained disciplined and selective — prioritizing platforms with regulatory tailwinds, recurring revenue, and technology differentiation. Landmark deals including American Water Works’ $19.1B acquisition of Essential Utilities and Parker-Hannifin’s $9.25B purchase of Filtration Group defined the year’s upper end, while private equity roll-ups continued to dominate the lower middle market. The report covers subsector investment themes, public company performance, EV/EBITDA trading multiples, top acquirer activity, and The McLean Group’s 2026 outlook for the water economy. […]
