Kimley Horn Net Worth: Estimate Explained for the Firm

Kimley-Horn is a private American engineering and planning consulting firm, not an individual, and its financial scale is best expressed through valuation estimates derived from its reported revenue of approximately $2.8 billion (2025). Because the firm is privately held, there is no publicly audited balance sheet to pull a precise "net worth" from, so every figure you see on aggregator sites is an estimate built from revenue multiples, headcount data, and industry rankings. The most reasonable working estimate for the firm's equity value (what most sites call "net worth" for a company) lands somewhere in the range of $2 billion to $4 billion, depending on the valuation methodology and the margin assumptions used.

Firm or individual? Getting the search right first

Most people who search "Kimley-Horn net worth" are looking for information about the firm, Kimley-Horn and Associates, Inc. If your search is really about <a data-article-id="1F426316-8241-4F80-9888-7F698CADF09F">Lincoln Kienholz net worth</a>, the key distinction is still whether you are asking about a private firm valuation or an individual’s publicly verified personal wealth. If you meant Lou Kerner net worth, the same private-versus-individual distinction applies: you want a documented personal wealth disclosure, not an inferred company valuation. , a well-known engineering, planning, and design consultancy headquartered in the United States. The name can cause some confusion because it was founded by three people: Bob Kimley, Bill Horn, and Ed Vick. The name blends two of those founders, which is why some readers assume "Kimley Horn" is a single person's name. It isn't. There is no prominent individual in public records named "Kimley Horn" as a standalone person.

There is also a separate entity, the Kimley-Horn Foundation, that appears in search results and is sometimes mistaken for the firm or for a wealth vehicle associated with it. The Foundation is a nonprofit and has nothing to do with the company's valuation or equity. If you landed here after searching for a founder's personal wealth, the section below on individual wealth covers how that typically works for a firm like this.

The headline estimate: what Kimley-Horn is worth

Kimley-Horn reported revenue of approximately $2.8 billion in 2025, according to Wikipedia's company profile and consistent with the firm's own ENR ranking disclosures. ENR (Engineering News-Record) ranked Kimley-Horn #8 out of 500 top design firms in 2025, a ranking that is explicitly based on revenue and earnings, which gives you a solid independent confirmation that the $2.8 billion figure is in the right ballpark.

For a professional services firm like Kimley-Horn, valuation multiples in the engineering and consulting sector typically run between 0.8x and 1.5x annual revenue for equity value, depending on profitability, growth rate, and market conditions. Applying that range to $2.8 billion gives an estimated equity value (the closest thing to "&lt;a data-article-id=&quot;17EA2CA1-8326-47BF-B6F4-33E09AE6F3EA&quot;&gt;&lt;a data-article-id=&quot;1F426316-8241-4F80-9888-7F698CADF09F&quot;&gt;&lt;a data-article-id=&quot;8B81CF7C-A716-44FA-859E-78BF441A5A8A&quot;&gt;net worth</a></a></a>" for a company) of roughly $2.2 billion to $4.2 billion. A midpoint estimate of around $3 billion is a reasonable working figure, though no public audited number confirms this.

Private-firm valuation sites like PrivCo categorize Kimley-Horn explicitly as a private company and use similar revenue and EBITDA-based methods to produce their estimates. Because they work from indirect inputs rather than disclosed financials, their numbers can shift meaningfully from year to year as revenue and headcount data updates.

How these net worth estimates are actually built

When a website publishes a "net worth" or "valuation" figure for a private company, it is almost never pulling from an audited filing. Instead, aggregators and valuation platforms piece together estimates from a handful of inputs and apply a formula. Here is how that typically works for a firm like Kimley-Horn.

1. Revenue estimate: Sites pull publicly available revenue figures (like Wikipedia's cited $2.8 billion for 2025) or produce their own proprietary estimate based on industry filings, government contract databases, and press releases.
2. EBITDA or margin proxy: For consulting and engineering firms, EBITDA margins typically range from 10% to 20%. Sites pick a margin assumption and multiply by revenue to get an operating earnings estimate.
3. Valuation multiple: A revenue multiple (commonly 0.8x to 1.5x for this sector) or an EBITDA multiple (commonly 8x to 14x) is applied to produce an enterprise value.
4. Net debt adjustment: To convert enterprise value into equity value (what owners actually "own"), net debt is subtracted. For most professional services firms, this adjustment is modest.
5. Headcount cross-check: Employee counts (Wikipedia cites 9,000+; Revelio Labs estimates closer to 10,900 in 2025 with 17.1% year-over-year growth) can validate revenue estimates using revenue-per-employee benchmarks common in the industry.

The core accounting definition of net worth, assets minus liabilities, is sometimes used as an alternative method called the adjusted net asset approach. For a light-asset business like an engineering consultancy, this method often produces a lower number than the revenue or earnings multiple approach, because the firm's most valuable assets are its people and client relationships, not buildings or machinery. This is why different sites can publish very different "net worth" figures for the same company: they are using different methods, and none of them is definitively correct.

What drives Kimley-Horn's financial scale

Kimley-Horn's business model is the main reason its valuation is as large as it is. The firm operates as a pure professional services consultancy, which means its revenue is almost entirely fees for intellectual and technical work rather than products or capital-intensive construction. That structure tends to produce strong margins relative to revenue, which is exactly what valuation multiples reward.

The firm's service breadth is unusually wide for a consultancy of its type. It covers development services, roadway design, structural engineering, environmental engineering, surface water management, transportation engineering, energy consulting, landscape architecture, aviation consulting, and even software. That diversity reduces dependence on any single sector and supports consistent revenue across economic cycles.

• 140+ office locations across the United States as of 2025, providing geographic revenue diversification
• 10,900+ employees in 2025 (up from roughly 8,100 in 2023), reflecting rapid organic and expansion-driven headcount growth
• ENR Top 500 Design Firms ranking of #8 in 2025, based on revenue and earnings, up from lower positions in prior years
• 65% organic revenue growth reported in the Midwest region over a single year, indicating strong regional momentum beyond just firmwide averages
• Individual office growth examples like Salt Lake City expanding from 15 to 130 employees over seven years, illustrating sustained market penetration

The combination of rapid headcount growth, wide geographic reach, and diversified service lines is exactly the profile that valuation models reward with higher multiples. When a site estimates Kimley-Horn's value above a simple 1x revenue figure, those scale and growth signals are usually the reason.

If you were looking for a founder or partner's personal net worth

The firm's founders were Bob Kimley, Bill Horn, and Ed Vick. Their personal net worth has never been publicly disclosed or verified through audited sources. For a firm of Kimley-Horn's scale, senior partners and founders who held equity stakes over decades could realistically accumulate personal wealth in the tens of millions to hundreds of millions of dollars, depending on their ownership percentage, any buyout arrangements, and how long they held equity before transitioning out. But that is a structural inference, not a documented figure.

A concrete example from public records: Mark S. Wilson served as CFO starting in 1992, became president in 2002, and served as chairman from 2009 to 2015. Someone in that role at a firm generating this level of revenue would typically accumulate meaningful equity over that time horizon, but no public source documents his personal net worth with specifics. Any website publishing a precise dollar figure for a Kimley-Horn founder's personal wealth should be treated skeptically unless it cites a verified disclosure, such as a regulatory filing or a credible journalistic investigation.

Individual wealth derived from a private firm like this typically comes from three channels: equity ownership (the most significant), annual compensation (salary, bonuses, profit distributions), and any proceeds from partial or full ownership sales. Without access to the firm's ownership structure or compensation records, any personal net worth figure for a Kimley-Horn founder is an educated guess at best. This is similar to the situation you'd encounter researching the personal wealth of principals at other private professional services firms.

Comparing what the numbers actually tell you

How to verify the numbers yourself, right now

The most practical way to cross-check any "net worth" figure you find for Kimley-Horn is to work backward through the inputs the site used. Here are the concrete steps to do that today.

1. Find the revenue assumption: Does the site cite $2.8 billion or a different figure? Check whether it matches the 2025 revenue year cited by Wikipedia and consistent with ENR's #8 ranking. If a site uses a significantly lower or higher revenue figure, that is likely the source of the discrepancy.
2. Check the valuation multiple applied: Professional services firms are typically valued at 0.8x to 1.5x revenue or 8x to 14x EBITDA. If a site implies a much higher or lower multiple, look for an explanation. A very high multiple might be inflating the estimate; a very low one might be using outdated data.
3. Confirm headcount: Cross-reference employee counts against Wikipedia's 9,000+ figure and Revelio Labs' 2025 estimate of approximately 10,900 employees. If a valuation site is using 5,000 employees as a base, its revenue estimate is probably outdated.
4. Look at the ENR ranking: Kimley-Horn's own published claim of #8 in ENR's 2025 Top 500 Design Firms is a publicly verifiable milestone. ENR explicitly states its rankings are based on revenue and earnings, so this functions as an independent revenue-scale confirmation.
5. Read the site's methodology notes: Reputable aggregators like PrivCo and CompWorth include some disclosure of how they produce estimates. If a site gives you a net worth number with no methodology note at all, treat it as unverified.
6. Check citation dates: A figure labeled as reflecting 2022 or 2023 data will be meaningfully lower than a 2025 estimate given the firm's 17% annual headcount growth rate. Always note the data year before accepting any figure as current.

On this site, each profile page includes citations and data sourcing notes so you can trace where any specific number originated. When you are on a Kimley-Horn profile page, look for the methodology or sourcing section, which will tell you whether the estimate is built on revenue multiples, asset-based calculations, or a blend of both. That context is what separates a grounded estimate from a number someone pulled out of thin air.

One final note worth keeping in mind: net worth estimates for private companies are genuinely fluid. They change as revenue grows, as interest rates affect valuation multiples, and as the firm's ownership or debt structure shifts. The $2.8 billion revenue figure and the resulting $2 billion to $4 billion valuation range are the most defensible estimates available right now based on public data, but they are not fixed facts. Treat them as a calibrated approximation and revisit them as new ENR rankings or headcount data becomes available. If you are researching comparable figures for other private-firm principals or business leaders, the same verification framework applies across the board.
