Read them together: a large backlog is not necessarily profitable work, reported earnings do not guarantee cash collection, and a company’s growth is harder to judge without understanding its contract and business mix. There is no universal margin, backlog, DSO, leverage, or valuation cutoff for the sector.
1. Project margins show whether growth is profitable
Track gross margin, operating margin, and net income over several years, using segment results where available. Revenue growth alone can conceal rising project costs or deteriorating estimates. Construction contracts may span multiple periods, so a margin trend is more informative than one quarter in isolation.

Granite Construction reported Construction gross profit margins of 15.7% in 2025, 14.4% in 2024, and 10.9% in 2023. Those are Granite-specific results, not industry targets. The company notes that revenue, gross profit, and operating cash flow can vary significantly with project progress, outstanding change orders and claims, and contract payment terms (Granite Construction 2025 Form 10-K).
When management highlights adjusted EBITDA or another non-GAAP measure, read its definition and reconciliation, then compare it with GAAP operating income, net income, and cash flow. Construction Partners cautions investors against treating non-GAAP measures in isolation or as substitutes for GAAP information (Construction Partners fiscal 2025 Form 10-K).

2. Backlog matters only when its definition and risks are clear
Backlog can indicate future activity, but it is not a standardized promise of revenue, timing, or profit. Before comparing headline totals, determine what each issuer counts, how much work is formally contracted and funded, when it may convert to revenue, and whether a few projects, customers, or regions dominate it.
- Separate contracted work from less-certain awards. Identify executed contracts, funded work, apparent low bids without signed contracts, claims, and pending change orders.
- Check contract economics. Fixed-unit-price and lump-sum work put cost-estimate and execution risk on the contractor. Sterling Infrastructure says lump-sum work generally presents greater risk to the contractor, though it can yield more profit if completed below estimate.
- Look for concentration and conversion detail. A large total is less useful without context on customer and project concentration and expected timing.
The definition can materially change the number. Sterling reported backlog of $3.01 billion at December 31, 2025, up from $1.69 billion a year earlier, and excludes apparent low bids until a customer formally executes a contract. Construction Partners reported $3.0 billion at September 30, 2025, comprising $2.2 billion on contracts in progress or executed and $0.8 billion of low-bid/no-contract projects. It includes projects when awarded and funding is considered probable, and describes backlog as a non-GAAP industry measure. These totals are not directly comparable (Sterling Infrastructure 2025 Form 10-K; Construction Partners fiscal 2025 Form 10-K).
3. Cash conversion tests the quality and timing of earnings
Compare operating cash flow with net income across multiple periods. Then inspect accounts receivable, contract assets and liabilities, retainage, and working-capital movements. Construction revenue recognition follows project progress, while billing milestones, customer acceptance, and collection schedules can put cash inflows in a different period from reported earnings.
Granite says private-sector customers can pay more slowly than public-sector customers, and contracts often retain a specified percentage of payments until completion and acceptance. Its net cash provided by operating activities was $468.916 million in 2025, $456.343 million in 2024, and $183.707 million in 2023. These are company-specific results, not a sector benchmark (Granite Construction 2025 Form 10-K).
Use each issuer’s definition when analyzing days sales outstanding (DSO). Quanta Services calculates DSO using receivables—including retainage and unbilled balances—plus contract assets less contract liabilities, divided by average daily quarterly revenue. On that basis, Quanta reported 60 days at December 31, 2025, compared with 59 days a year earlier and a five-year historical average of 75 days. That definition matters when comparing it with companies that calculate DSO differently. Quanta also notes that project starts can require spending before related receivables are billed and collected, while delayed or unpaid change orders and claims can weigh on cash flow (Quanta Services 2025 Form 10-K).
4. Debt, liquidity, capital spending, and bonding affect execution capacity
Review gross and net debt, interest burden, debt maturities, available liquidity, capital expenditure needs, and acquisition spending alongside operating cash flow. Contractors may need working capital and equipment to begin new projects; acquisitions can also alter reported growth and leverage.
Bonding capacity is an operating consideration, not just a balance-sheet footnote. Sureties can weigh capitalization, working capital, total contract size, past performance, management expertise, existing bonded backlog, and prevailing underwriting standards. Sterling identifies these factors in discussing bonding (Sterling Infrastructure 2025 Form 10-K).
Recommended Free Tools
Quanta’s credit agreement specifies a maximum consolidated leverage ratio of 3.5:1 and minimum consolidated interest coverage ratio of 3.0:1, with temporary leverage covenant accommodation for certain qualifying acquisitions. These are contractual terms for Quanta, not recommended limits for other construction companies (Quanta Services 2025 Form 10-K).

5. Business mix determines which comparisons are fair
Before comparing margins, growth, or valuation multiples, identify what the company builds and owns. Heavy-civil work can sit alongside building construction, specialty contracting, materials, or infrastructure services. Also note public versus private customers, geography, labor and material exposure, seasonality, project concentration, contract type, and acquisition effects.
Construction Partners describes work in roads, highways, bridges, airports, and site work for public and private customers. Sterling reports multiple business solutions and discusses differences in contract forms and risk allocation. These mixes affect margin and backlog interpretation; compare companies with similar operations and use each company’s own definitions rather than applying one issuer’s measures to another.
6. A practical screen for comparing companies
For each company, record these measures over several years and use consistent periods and definitions:

Pick the symptom - the matching free tool is one click away.
- Gross and operating margin trends, by segment where reported, alongside GAAP net income.
- Backlog relative to revenue, including its definition, award and funding status, expected timing, contract mix, and customer or project concentration.
- Operating cash flow relative to earnings, plus working-capital changes, contract assets and liabilities, retainage, and the issuer’s DSO definition and trend.
- Net debt, interest coverage, maturities, liquidity, capital spending, and acquisition funding.
- Surety and bonding access, including how much existing backlog is bonded where disclosed.
- Business mix, geography, customer type, seasonality, contract structure, and acquisition-driven growth.
- Valuation multiples applied consistently to comparable earnings or cash-flow measures, with GAAP results and non-GAAP reconciliations visible.
Treat company-reported figures as evidence about that issuer and period—not as sector norms or automatic buy/sell signals. U.S.-listed issuer filings are most directly applicable to investors comparing those companies.
