Playbook

Exit playbook — construction

The single largest driver of purchase-price outcome is preparation depth. These are the levers that move the needle in construction exits.

1
Address project accounting quality before diligence
12-24 months pre-sale
Percentage-of-completion accounting is the #1 diligence challenge. Buyers hire QoE specialists to unwind buried job losses.
2
Document backlog quality with reputable owner / GC references
9-12 months pre-sale
Backlog is only worth what buyers believe about the counterparties. Documented multi-year owner relationships materially lift multiples.
3
Confirm bonding capacity supports the growth story you're selling
6-12 months pre-sale
Surety carrier confirmation is required for any strategic buyer. Get bond capacity confirmed in writing 6+ months pre-close.
4
Get key superintendents + PMs under retention agreements
6-9 months pre-sale
Workforce retention is critical in specialty construction. Superintendent turnover post-close can destroy project profitability.

FAQ

Commercial Generator Systems exits, answered

What is a commercial generator systems business worth?

Owner-operator commercial generator systems businesses trade at 3x–5x SDE for typical $500K–$3M SDE ranges. At $3M+ EBITDA scale the same operators sell at 5.5x–9x EBITDA. Multiples in this category are ebitda-based and data-sourced from AGC / FMI Construction Industry M&A Report 2025 + IBBA Q4 2024. Where you land in the range is driven by growth trajectory, revenue mix, customer concentration, and management-team depth beyond the owner.

Active buyer archetypes in construction include National contractor / vertical integrator, Construction PE platform, Family office / long-hold.

What drives multiple expansion in commercial generator systems?

Commercial generator system contractors (hospital, data center, mission-critical) with Generac Industrial, Kohler, Cummins, and Caterpillar dealer certifications and NFPA 110 emergency-power-system service contracts trade at premium. Beyond the industry-specific factor, the universal drivers in construction are bonding capacity and clean surety-carrier relationship; multi-year project backlog with reputable gcs / owners; union / prevailing-wage workforce where applicable (or explicitly non-union).

What are the biggest risks in selling a commercial generator systems business?

Commercial generator demand is capex-cycle exposed with long-lead-time equipment; buyers scrutinize your equipment-allocation position with OEMs. Buyers in this category also standardly scrutinize project profitability variance and buried job losses and bonding capacity limits growth. Addressing these in advance in a well-prepared CIM materially reduces retrade risk during diligence.

What revenue range makes commercial generator systems sellable to a professional buyer?

Typical transaction range for commercial generator systems is $1.0M–$20M in annual revenue. Below that, buyer pool narrows to individual and small-search-fund. Above that, PE platforms and strategics dominate. NAICS code 238210 — buyers screen by NAICS in most deal sources.

How long does it take to sell a commercial generator systems business?

From the day you engage a broker to close, expect 6–12 months for a well-prepared business in construction. The prep work — financial cleanup, addbacks documentation, key-employee retention agreements, real estate lease sorting — is where 3-6 months of the timeline hides. Starting that early is what separates a full-multiple exit from a discounted one.
