Engineering firms typically sell for 4–7× EBITDA or 0.4–0.8× net revenue (billings minus subconsultant pass-throughs). Backlog quality and PE licensure continuity are the primary valuation drivers. Firms with 12–18 months of signed backlog and multiple PE-licensed staff command top-of-range multiples.
Engineering firm backlog (signed contracts not yet billed) represents future revenue certainty. Buyers pay for backlog because it eliminates the uncertainty of business development. A firm with 1.5× annual revenue in signed backlog is significantly more valuable than one relying on repeat business without signed contracts.
Net revenue (also called net billings or net fees) equals total billings minus subconsultant and reimbursable costs passed through to clients. Engineering firms are priced on net revenue because subconsultant pass-throughs inflate gross revenue without adding to firm profitability. Always use net revenue when comparing engineering firm valuations.
Yes — SBA 7(a) is commonly used for engineering firm acquisitions under $5M transaction value. The buyer must demonstrate relevant technical or management experience. A critical consideration: the purchase agreement must address PE licensure continuity — if the selling owner is the only licensed PE, the firm may not legally operate until the buyer obtains their PE license.
Owner-held PE licensure (the only licensed Professional Engineer is the selling owner) is the single largest value discount in engineering firm M&A. Without PE licensure continuity, the firm cannot legally stamp drawings and loses billable capability. Buyers require either: a transition period where the seller remains as licensed PE, the buyer holds a PE license, or other staff PEs are contractually retained.
