The quickest way to misread a contractor is to treat a large backlog as guaranteed sales and a rising margin as proof of permanently better economics. A sound analysis does three things in order: reconcile what the company counts as backlog, test how much of that work is likely to convert into revenue and profit, and measure whether a small number of customers or related funding sources drive the business.
Use the company’s latest annual report, 10-K and earnings materials. Record definitions before comparing companies, calculate margins on the same segment and accounting basis, and connect every change to project-level causes such as labor, materials, subcontractors, delays, productivity and cost-to-complete estimates. The examples below are from U.S. public-company filings and illustrate the method, not sector-wide benchmarks.

What each metric tells you—and what it cannot tell you
Backlog is the company’s own estimate of future work associated with contracts, awards or other commitments. It is not a standardized measure. One issuer may count only unearned revenue on executed contracts; another may include awarded work when funding is considered probable. Some companies include options, claims, notices to proceed, or their share of unconsolidated joint ventures.

Margin shows how much revenue remains after the costs included in the chosen profit measure. For construction operations, the basic calculation is gross margin = gross profit ÷ revenue. A margin percentage is meaningful only when the period, segment, contract mix and accounting presentation match.
#1 Best Overall
Customer concentration measures dependence on individual buyers or economically related sources of demand. Start with each named customer’s revenue share, then examine concentration by agency, end market, geography, project and funding program. A company can have many legal customers but still depend on one transportation budget, commodity cycle or regional construction market.
These metrics answer different questions. Backlog addresses potential future volume, margin addresses expected economics on the work recognized, and concentration addresses demand and collection exposure. None is sufficient alone.
Step 1: Reconcile the backlog definition before comparing totals
Find the backlog policy in the latest filing. Copy the definition and the reconciliation disclosures into your working notes. Do not put two headline totals in a table until you know that they represent comparable commitments and economic shares.

- Executed contracts: Work legally signed by both parties, often the most committed category.
- Awards or letters of intent: Work selected by the customer but not necessarily fully contracted.
- Funding-dependent work: Projects included only to the extent management believes funding is probable.
- Notice-to-proceed work: Contracted work authorized to begin; the notice may be a useful timing signal.
- Options, claims and change orders: Potential additions whose probability and value can vary materially.
- Joint ventures: The company may include its proportionate share, or a different amount under its policy.
For example, the construction industry’s definitions differ: one 2025 annual report describes backlog as unearned revenue expected on executed contracts, while Construction Partners’ 2026 annual report describes including projects when awarded and when funding is believed probable. Those amounts should not be compared without adjustment.
Separate gross contract value from the company’s economics
Determine whether the figure is gross contract revenue or the company’s expected share. AECOM’s 2024 Form 10-K explains that its backlog can include a proportionate share of unconsolidated joint ventures and gross revenue containing third-party or pass-through costs. Materials and subcontractor amounts may inflate a headline backlog while contributing relatively little gross profit or cash generation to the contractor.
Check exclusions and timing
Ask what is omitted. Revenue earned and completed in the same reporting period may never appear in an ending backlog balance. Also note whether maintenance, short-cycle work, claims, or particular contract types are excluded. A lower backlog can therefore reflect a different business mix rather than weaker demand.
Capture the measurement date, currency, reporting segment and whether the figure is recurring, funded or conditional. Keep signed work separate from less-certain categories instead of presenting one blended number.

Backlog is a pipeline, not a promise. Granite Construction’s 2025 annual report states: “Our backlog may not be realized or may not result in profits and may not accurately represent future revenue.” Use that warning as an analytical rule: every backlog dollar needs a conversion assessment.
Rank #2
Classify certainty
| Backlog category | Questions to ask | Typical analytical implication |
|---|---|---|
| Executed and funded contract | Is work authorized? What is the remaining term and schedule? | Higher commitment, but still exposed to execution, pricing and termination terms. |
| Executed but funding-dependent | What appropriation, financing or approval remains? | Timing and amount can move if funding is delayed or reduced. |
| Award or letter of intent | Has a definitive contract been signed? Are approvals outstanding? | Less certain than executed work; cancellation or re-scoping remains possible. |
| Option, claim or change order | Is exercise or settlement probable, and at what value? | Do not treat as base-case revenue without evidence of approval. |
| Joint-venture or pass-through amount | What is the company’s economic share and expected margin? | Gross dollars may overstate the contractor’s own value capture. |
Review termination-for-convenience clauses, customer default rights, remaining approvals, schedule milestones, litigation, site access and known delays. A filing discussing backlog composition warns that defaults, cancellations, scope changes, delays and cost adjustments can prevent expected realization.
Build a backlog bridge
When disclosures permit, reconcile periods with:
Beginning backlog + new awards − revenue recognized ± adjustments = ending backlog
Adjustments can include cancellations, scope changes, foreign-exchange movements, acquisitions, divestitures and changes in the company’s definition. If the reported bridge does not tie, document the reason rather than forcing the arithmetic.
Compare backlog growth with revenue growth over several periods. Backlog rising faster than revenue can indicate expansion, longer project durations or slower starts; it can also reflect lower-quality awards. Backlog falling while revenue rises may simply mean the company is converting older work or operates in short-cycle contracts. Examine operating cash flow and receivables alongside the bridge; backlog movement alone does not explain cash generation.
Estimate timing and duration
Divide backlog into work expected to be recognized within 12 months and later periods when the company discloses that split. Long-duration infrastructure work can provide visibility but exposes the estimate to more inflation, design changes and schedule risk. A short-duration contractor may show a smaller period-end balance while turning work into revenue quickly.
Step 3: Analyze margins on a consistent basis
Calculate the right margin
Use the company’s reported construction segment when available and keep materials, engineering, real estate or other operations separate. Calculate:
Gross margin = construction gross profit ÷ construction revenueOperating margin = construction operating income ÷ construction revenue, if segment operating income is disclosed.Margin change = current margin − prior-period margin, expressed in percentage points.
Do not compare one company’s consolidated operating margin with another company’s construction gross margin. Confirm whether depreciation, corporate allocations, gain recoveries, insurance proceeds or unusual items are included.
Use the trend, not a single percentage
Granite Construction’s construction segment gross profit margin was 10.9% in 2023, 14.4% in 2024 and 15.7% in 2025. These are historical, company-specific figures from its 2025 annual report, not a target or normal range for contractors. The useful question is what changed and whether the change is repeatable.
Trace the operational causes
- Labor: Wage rates, overtime, staffing shortages, turnover and productivity.
- Materials: Price inflation, procurement timing, escalation clauses, shortages and waste.
- Subcontractors: Bid coverage, pricing, availability, performance and replacement costs.
- Schedule and weather: Delays can add supervision, equipment, financing and labor costs.
- Design and scope: Owner-directed changes, differing site conditions and rework alter expected cost.
- Claims and recoveries: Settlements or back-charge recoveries may lift a period without improving core execution.
- Cost-to-complete estimates: A revised forecast can change profit recognized on work already underway.
Separate mix effects from execution. A year with more high-margin specialty work can improve the reported margin even if individual project performance is unchanged. Conversely, a large fixed-price project nearing completion may create a temporary drag or benefit as final costs become clearer.
Understand cost-to-cost revenue recognition
Under a cost-to-cost method, progress is generally estimated as costs incurred divided by estimated total costs. Revenue and profit are recognized according to that progress measure, subject to the company’s accounting policy. If estimated total cost rises, the expected profit on the remaining work falls and reported profit on the project can be reduced. The reviewed 2025 annual report says these estimates depend on assumptions about future events; they can change with productivity, labor and materials, delays, scope and claims.
Look for revisions to contract estimates, loss provisions, unfavorable project performance, write-downs and changes in remaining gross profit. A rising company-wide margin is less reassuring if it comes with repeated negative revisions on older fixed-price jobs.
Step 4: Measure customer concentration and correlated exposure
Calculate named-customer shares
For each disclosed customer, calculate customer revenue ÷ total revenue × 100. Keep the numerator and denominator from the same fiscal year and state whether the customer is a public agency, private owner, prime contractor or another relationship.
Granite Construction reported $446.6 million of 2025 revenue from Caltrans, equal to 10.1% of total revenue. Its filing said no other customer individually exceeded 10% in the years shown. This demonstrates how to read a disclosure; it is not a universal safe or unsafe cutoff.
Look beyond the legal customer name
- Related agencies: Several state departments or municipalities may rely on one state or federal funding program.
- End markets: Transportation, water, power, housing and industrial demand can move together.
- Geography: Regional weather, permitting, tax receipts and construction cycles can affect many customers at once.
- Project concentration: A single megaproject can dominate backlog even if revenue is spread across entities.
- Relationship layer: Revenue from several prime contractors may ultimately depend on one owner.
Also inspect receivables and backlog concentration where disclosed. A revenue-share calculation does not show whether collections are slow or whether future awards depend on the same customer.
Assess diversification quality
Granite describes pursuing public and private work across end markets, geographies, procurement methods and contract types as a diversification approach. Evaluate whether that variety changes economic exposure or merely changes the customer’s legal name. A contractor serving multiple agencies in one transportation program remains exposed to that program’s funding and bid environment.

Present “not stated” when a filing does not disclose a comparable value. Do not infer that an undisclosed customer is small, that all backlog is funded, or that a margin is comparable merely because both companies label it “gross profit.”
A practical worksheet for a single company
- Set the scope. Record fiscal year, reporting currency, consolidated versus segment results, and whether the company is a public filer.
- Copy the backlog definition. Note executed contracts, awards, funding tests, options, claims, joint ventures, pass-through amounts and exclusions.
- Split backlog by certainty and timing. Identify funded, conditional, optional and disputed amounts, plus expected recognition periods.
- Construct the bridge. Reconcile beginning backlog, awards, revenue recognized and adjustments to ending backlog where possible.
- Calculate margins. Use the same segment and accounting basis for each year; show percentage-point changes.
- Explain the change. Read project-risk and segment commentary for labor, materials, subcontractors, delays, productivity, scope and estimate revisions.
- Calculate concentration. Divide each named customer’s revenue by total revenue and list related agencies, end markets, regions and major projects.
- Check cash and receivables. Compare operating cash flow, contract assets, receivables and collections with reported growth.
- Write the conclusion in probabilities. Describe what is committed, what is conditional, what margin is supported by current evidence and which exposures could change the outcome.
Common analytical mistakes and how to correct them
Calling backlog guaranteed revenue
Correction: Label it potential future work and identify funding, cancellation, timing and execution conditions.
Ranking companies by backlog dollars alone
Correction: Normalize definitions, joint-venture shares, pass-through content, contract duration and segment scope first.
Using a sector “normal” margin
Correction: Use each company’s multi-year trend and explain mix and project causes. The Granite figures above are not an industry benchmark.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Ignoring estimate-driven profit
Correction: Track cost-to-complete revisions, loss provisions and claims; a reported margin can change before cash is collected.
Treating a 10% customer threshold as a safety rule
Correction: Use disclosed percentages as company-specific signals, then test related agencies, funding programs, projects and receivables.
Assuming legal-customer diversity equals economic diversity
Correction: Trace who ultimately pays, which market funds the work and whether projects share the same regional or commodity exposure.
How to state the final investment or credit view
A useful conclusion separates three judgments:
- Volume visibility: How much backlog is executed, funded and scheduled, and how much is conditional?
- Profitability quality: Are margins stable after adjusting for mix, and are project estimates being revised favorably or unfavorably?
- Demand resilience: Would the loss, delay or budget reduction of the largest customer, agency, project or end market materially affect revenue and cash?
Then state the principal uncertainty. For example, a contractor may have several years of reported backlog but a high share of joint-venture and pass-through work, while recent margin gains depend on favorable project closeouts. Another may have a smaller backlog but mostly funded contracts, short conversion periods and diversified end markets. The larger headline number does not decide which profile is stronger.
