Valuing an EV charging installation company requires isolating EBITDA, understanding project economics and customer mix, evaluating recurring revenue potential, and assessing technical capability and market positioning.

Start with EBITDA. Take 12 months of revenue from two sources: (1) Installation revenue (number of installations × average revenue per install), (2) Recurring maintenance/monitoring revenue (annual contracts × average annual value). Subtract: (1) Direct labor (installation crew wages, payroll taxes, benefits: typically 40-50% of installation revenue), (2) Equipment and parts (charger hardware, electrical materials, parts inventory: 15-25% of installation revenue), (3) Overhead (office, management, accounting, insurance: 8-12% of total revenue), (4) Marketing and business development (5-8% of revenue for growth-stage companies). What's left is EBITDA.

Example: EV charging installer

Installation revenue: 50 installations × $12K average = $600K Recurring maintenance revenue: 80 chargers under contract × $200/year average = $16K Total revenue: $616K

Direct costs: Installation labor: $280K (45-50% of installation revenue) Equipment/parts: $120K (20% of installation revenue) Recurring labor (maintenance): $8K Overhead (office, management, insurance): $60K (10% of revenue) Marketing/BD: $40K (6% of revenue) Total OpEx: $508K

EBITDA: $616K - $508K = $108K (18% of revenue)

Wait, that seems low. Many EV installers run 22-30% EBITDA because service work and recurring revenue are higher-margin. Let me recalculate with better recurring mix and cost structure.

Installation revenue: 50 installations × $13K = $650K (with larger DCFC projects, higher revenue) Recurring revenue: 120 chargers × $250 annual = $30K (better recurring uptake) Total revenue: $680K

Direct costs: Installation labor: $280K (42% of installation, more efficient crew) Equipment/parts: $130K (20% of installation) Recurring labor: $12K (40% of recurring revenue—low cost) Overhead: $68K (10%) Marketing: $48K (7%) Total OpEx: $538K

EBITDA: $680K - $538K = $142K (21% of revenue)

At 21% EBITDA margin, $680K revenue = $142K EBITDA. At 7x EBITDA (mid-range multiple for solid EV installer): Enterprise Value = $142K × 7 = $994K.

Now apply adjustments based on quality factors:

Project volume and growth: 50 installations on growing trajectory (+15% annually) = base multiple. 30 installations = -0.5x-1.0x (early stage, unproven). 80+ installations = +0.5x-1.0x (scale, market traction).

Customer mix diversification: Balanced (40% commercial, 30% fleet, 30% multifamily) = base. Fleet-heavy (60%+ fleet, pricing pressure) = -0.2x-0.3x. Concentrated (75% from one customer type or region) = -0.5x-0.75x.

Recurring revenue: 20%+ of total revenue from recurring contracts = +0.5x-0.75x (EBITDA margin uplift, customer lifetime value). 10-20% = +0.2x-0.3x. <10% = base (majority one-time).

Technical capability: Multi-OEM, L2+DCFC capable = +0.3x-0.5x (defensible, customer-sticky). Single-OEM or L2-only = -0.2x-0.3x (limited addressable market).

Licensing and credentials: Proper electrical contractor licensing, bonding = base (table-stakes). Missing or questionable licensing = -1.0x-1.5x (deal-killing risk).

Utility relationships: Active in 3+ utility programs, diversified deal flow = +0.2x-0.3x. Single utility program = -0.2x-0.3x (concentration risk). No utility partnerships = -0.3x-0.5x (dependent on organic sales).

Example valuation (strong installer): Base: $142K × 7x = $994K Adjustments: + Growing 18% annually (50 to 59 installations): +0.5x + Balanced customer mix (commercial/fleet/multifamily): +0.2x + 18% recurring revenue growing: +0.3x + Multi-brand technical capability (Tesla, Chargepoint, EVgo): +0.3x + Proper licensing, bonded and insured: base + Active in 4 utility incentive programs: +0.2x

Net: +1.5x Final multiple: 7x + 1.5x = 8.5x Final valuation: $142K × 8.5 = $1.207M

Example valuation (weaker installer): Base: $142K × 7x = $994K Adjustments: - 30 installations, no growth: -0.75x - Fleet-heavy (65% of revenue), price pressure: -0.2x - 5% recurring revenue, no growth strategy: -0.3x - Single-brand capable (Chargepoint only): -0.2x - Licensing status unclear, no bonding: -0.75x - Utility program-dependent (60% of revenue), policy risk: -0.3x

Net: -2.5x Final multiple: 7x - 2.5x = 4.5x Final valuation: $142K × 4.5 = $639K

The same EBITDA yields $1.207M (strong) vs. $639K (weaker)—a $568K valuation gap driven by growth, customer diversification, recurring revenue, and technical positioning.

Key considerations:

Subsidy/rebate dependency: Federal and state EV charging subsidies (IRA credits, state incentives) are time-limited (typically 2024-2026 programs). A company where 40-50% of revenue comes from subsidized customers faces risk if subsidies expire. Buyers model: what's revenue if rebates are cut by 50%? If answer is >15% revenue reduction, that triggers 0.3x-0.5x haircut. A company building recurring revenue and diversified customer base is less sensitive to subsidy changes.

Electrical workforce: EV charging installation requires licensed electricians (journeyman/apprentice level). Technician availability and retention are critical. A company investing in apprenticeship programs (hiring high school graduates, training toward journeyman) shows workforce pipeline and long-term capacity. Technician turnover >20% triggers concerns.

To increase valuation in 12-18 months: 1. Grow installations from 50 to 75 annually (add 25 installations; +$325K revenue, improves scale and adds +0.3x-0.5x multiple). 2. Build recurring revenue from 5% to 20% of total (enroll 150 chargers in maintenance contracts; +$50K annual recurring revenue, adds +0.4x-0.5x multiple, improves EBITDA margin). 3. Diversify customer mix (reduce fleet concentration from 60% to 35%; shift to commercial/multifamily; improves margin and adds +0.2x-0.3x). 4. Expand technical capability (add DCFC certification if L2-only; multi-brand capability adds +0.2x-0.3x). 5. Formalize utility relationships (secure preferred installer status with 3-4 utility programs; adds +0.2x-0.3x and ensures deal flow).

These moves can shift valuation from 4.5x ($639K) to 8x-8.5x ($1.14M-$1.207M)—a 79-89% increase in 18 months.
