Why construction businesses are different
Generic valuation tools miss what actually drives value in this vertical. AcquireLens scores these factors explicitly.
Backlog quality
Signed backlog is the closest thing to forward revenue a contractor has — but only if margin, start dates, and change-order exposure are verified.
Work-in-progress accounting
Over- and under-billings distort reported earnings more than in any other vertical. WIP schedules must be re-cast before a multiple is applied.
Bonding capacity
Surety limits cap the size of jobs a buyer can pursue post-close, and bonding often resets when ownership changes.
Project concentration
One large job can carry an entire fiscal year — and one dispute can erase it.
Fixed-price vs cost-plus mix
Contract type determines who absorbs material and labor inflation, which is the dominant margin risk in this vertical.
Skilled labor availability
Crew retention and foreman depth decide whether backlog can actually be delivered on schedule.
Equipment fleet and rental mix
Owned iron carries capex and maintenance drag; heavy rental reliance compresses margin but frees capital.
Retainage and cash cycle
Retainage held for months creates working-capital needs that never appear in an income statement.

AcquireLens AI Report
Construction — Acquisition Analysis
A self-perform specialty contractor with above-median gross margin, a well-priced twelve-month backlog, and disciplined change-order capture. Earnings are real but cash-cycle heavy: retainage and one large public project drive the majority of working-capital need, and estimating remains owner-held.

Business valuation factors
Each factor is evaluated in sequence, and every adjustment to the multiple is documented in the final report.
- 1
Backlog durability
Each contract in backlog is scored for margin, start certainty, owner creditworthiness, and cancellation terms before it supports value.
- 2
WIP accuracy
Percentage-of-completion assumptions are re-tested so over-billings are not mistaken for earnings.
- 3
Contract mix
Fixed-price, unit-price, and cost-plus revenue are separated because each carries a different inflation and dispute profile.
- 4
Customer and GC concentration
Exposure to a single general contractor, developer, or public agency is treated as concentration risk.
- 5
Owner dependence
Estimating, bidding, and relationship ownership held by the seller becomes a transition deduction.
- 6
Surety and insurance
Bonding headroom, loss history, and experience modification rate are reviewed for post-close continuity.
- 7
Equipment condition
Heavy iron, attachments, and hour meters are appraised against book value to expose deferred replacement capital.

Overall recommendation
Proceed with Caution
A self-perform specialty contractor with above-median gross margin, a well-priced twelve-month backlog, and disciplined change-order capture. Earnings are real but cash-cycle heavy: retainage and one large public project drive the majority of working-capital need, and estimating remains owner-held.
Key risks
- high
Single-project concentration
One municipal contract is 31% of current backlog.
- high
Net over-billing position
Reported earnings flatter cash by roughly $410K.
- medium
Owner-led estimating and bidding
No second estimator; win rate tied to the seller.
- medium
Bonding reset at close
Surety indemnity must be re-underwritten to the buyer.
Key strengths
- Backlog coverage — 1.2x trailing revenue
- Gross margin — 22.4% vs 19% median
- EBITDA margin — 9.8% vs 8% median
- Hire a second estimator to de-risk bid volume before close
