Selling an engineering firm in New Hampshire: common questions
How much is an engineering firm in New Hampshire worth?
Engineering firms typically sell for 5.5x-7.5x EBITDA, or 2.5x-3x SDE for smaller owner-operated engineering firms, with most deals in the $0.7M - $50M range. Buyers tend to pay more for double-digit ebitda growth, diversified, low-concentration client base, leadership bench beyond the founder and hard backlog and repeat public-sector work, and less where they see dependence on a single leader, client concentration, volatile end markets and weak contract and wip management. These are industry-wide ranges from ROG + Partners, MNP Engineering & Construction Quarterly Update Q1 2026 and others, not an appraisal of your firm.
