An auto glass repair business typically sells for 2.0x–3.5x Seller's Discretionary Earnings (SDE), or 0.3x–0.6x annual revenue, with ADAS-equipped, insurance-networked operations commanding the premium end and basic replacement shops at the lower end. The U.S. auto glass industry generates approximately $7 billion in annual revenue through roughly 8,000 independent glass shops and thousands of mobile service operations, alongside national chains like Safelite that dominate market share. The industry is consolidating rapidly as ADAS technology raises the capital and training requirements for competitive operation.

Seller's Discretionary Earnings — the owner's total economic benefit including salary, benefits, and add-backs — is the standard valuation method for auto glass businesses. Common add-backs include the owner's salary, vehicle expenses, personal insurance, and any one-time equipment purchases. Companies trade between 2.0x and 3.5x SDE, with the range driven by ADAS calibration capability, insurance network status, mobile fleet, technician depth, and commercial account base. A shop at 2.0x operates without ADAS calibration, relies on walk-in traffic without insurance network routing, has the owner as primary installer, and lacks commercial accounts. A shop at 3.5x has full ADAS calibration capability capturing $200–$400 per eligible job, direct insurance network billing generating routed claims, a mobile fleet serving on-site customers, multiple trained installers, and 15+ commercial accounts.

Revenue multiples for auto glass businesses fall between 0.3x and 0.6x, reflecting the moderate margin profile typical of automotive services. Net margins range from 10% to 20% depending on service mix, ADAS calibration penetration, and insurance reimbursement rates. Revenue multiples should be evaluated alongside ADAS capability — shops performing calibration on 40%+ of replacements generate meaningfully higher margins per job than replacement-only operations.

For larger auto glass operations generating $500K or more in EBITDA — typically multi-location businesses with mobile fleets and commercial account portfolios — institutional buyers use EBITDA multiples in the 4x to 6x range. National glass networks and PE-backed automotive services platforms evaluate geographic coverage, ADAS capability, insurance network depth, and fleet condition.

The unique valuation factor in auto glass is the ADAS calibration revolution that is creating a two-tier industry. Every modern vehicle with lane departure warning, automatic emergency braking, or adaptive cruise control requires sensor recalibration after windshield replacement. This isn't a niche add-on — it's becoming a mandatory component of the majority of windshield replacement jobs. The shops that have invested $30K–$60K in calibration equipment and technician training are capturing $200–$400 in additional revenue per eligible job that shops without the equipment cannot access. As the ADAS-equipped vehicle fleet grows, the revenue gap between equipped and non-equipped shops widens every year. Buyers understand this trajectory and price it explicitly: an auto glass business performing 3,000 replacements annually with 50% ADAS attachment generates $300K–$600K in calibration revenue that a non-equipped shop at the same replacement volume simply doesn't have. That calibration revenue stream, at a 3x SDE multiple, can represent $150K–$300K in additional business value — a return of 3–10x on the original equipment investment. For auto glass owners without ADAS capability, the investment calculus is straightforward: the equipment pays for itself within 12 months through calibration revenue and adds multiples of its cost in business value at sale. Delaying the investment means watching the most valuable segment of auto glass revenue flow to competitors and dealerships while your business becomes less attractive to every buyer category.

The auto glass M&A market is driven by industry consolidation around ADAS capability and insurance network scale. National chains expand through acquisition of independent shops with established insurance relationships. PE-backed automotive platforms build regional glass operations. Insurance companies prefer routing to ADAS-capable shops, creating organic consolidation pressure. For shops with calibration capability, insurance network status, and commercial account bases, the market offers competitive multiples. Non-equipped shops face an increasingly challenging buyer environment as the gap between ADAS-capable and non-capable operations widens.
