The Youngquist brothers, Harvey and Tim Youngquist, are the founders of Youngquist Brothers Inc., a Florida-based deep injection well drilling and construction company they started in 1971. Their most defensible estimated combined net worth range as of May 2026 sits somewhere between $200 million and $700 million or more, with the upper end driven significantly by the landmark $620 million sale of their rock mine properties to Martin Marietta in late 2024. That single transaction almost certainly represents the single biggest wealth event in the family's history, and it reshapes any estimate that predates it.
Youngquist Brothers Net Worth: Estimates, Drivers, and How to Verify

Who the Youngquist Brothers Are
Harvey Youngquist and Tim Youngquist built their business from the ground up, starting a drilling operation in Fort Myers, Florida in 1971 and formally incorporating as Youngquist Brothers Inc. in 1977. For decades they operated largely under the radar as a private industrial contractor, not the kind of public figure who shows up on celebrity net worth lists. Their company, headquartered at 15465 Pine Ridge Rd in Fort Myers, specializes in Class I deep injection wells, a highly technical niche in environmental and industrial construction. The company claims to have constructed 163 of Florida's 177 Class I deep injection wells, which is a staggering market share in a field most people have never heard of.
The family business has expanded beyond drilling. Youngquist Brothers Rock Inc., the quarrying arm, became a major land holder in Southwest Florida. Government records from the Mine Safety and Health Administration (MSHA) list both Harvey Youngquist and Tim G. Youngquist as mine controllers for that entity. The next generation is also involved: Brett Youngquist appears as an owner/principal in company filings and was quoted directly in the 2024 Gulfshore Business coverage of the Martin Marietta land deal, suggesting an active handoff of operations to the family's second generation.
Why the Numbers Vary So Much Depending on Where You Look
Here's the honest reality: the Youngquist brothers don't have a widely published net worth figure the way a Hollywood actor or pro athlete might. They are private business owners, not public company executives required to file insider ownership disclosures with the SEC. That means most net worth sites that mention them are extrapolating from limited data rather than citing verified financials. If you are comparing how net worth figures get estimated for non-household names versus celebrity stories like the kaulitz twins net worth, the same sourcing caveats apply net worth sites.
Revenue estimators like Growjo put Youngquist Brothers' annual revenue at roughly $35 million per year, but that is a model-generated estimate, not an audited figure. Converting revenue into net worth requires assumptions about profit margins, debt levels, asset values, and ownership stakes, and different sites make wildly different assumptions. Add to that the fact that the $620 million Martin Marietta land deal in 2024 happened after most legacy estimate databases were last updated, and you get a situation where pre-2024 figures can be off by hundreds of millions of dollars compared to what is likely accurate today.
There is also a naming complexity issue worth flagging: a Reddit post references a Schedule 13G filing connected to a Timothy Youngquist and shares held in trust. Without independently verifying that through SEC EDGAR directly, it is impossible to confirm whether that is the same Tim Youngquist, a relative, or an entirely different person. Confusion like this is common with private business figures who share names with other individuals in public records.
The Estimated Net Worth Range and How to Read It
Given what is publicly documented, here is the most defensible way to frame the Youngquist brothers' net worth as of May 2026. Think of it in three tiers:
| Scenario | Estimated Range | Key Assumptions |
|---|---|---|
| Conservative (pre-deal, ongoing business only) | $100M – $200M | Business equity based on ~$35M revenue at modest margins, no major liquidity events counted |
| Mid-range (post-deal, partial proceeds) | $300M – $500M | $620M sale proceeds split among family members and reinvested assets, after taxes and costs |
| High-end (full post-deal, combined family) | $600M+ | Full Martin Marietta sale attributed to family, plus business equity, real estate, and foundation assets |
The most realistic range for the Youngquist family collectively, accounting for the 2024 land sale, sits somewhere between $300 million and $600 million depending on how the proceeds were distributed and what tax and transaction costs looked like. No single published figure should be trusted as precise. Any site quoting a specific round number without explaining this context is guessing.
Where the Money Actually Comes From
Deep Injection Well Drilling
The core business is Youngquist Brothers Inc., the drilling and construction contractor. Constructing 163 of Florida's 177 Class I deep injection wells is not a small feat. These are industrial-scale environmental infrastructure projects commissioned by municipalities, utilities, and corporations. The company has won government contracts including a documented $10.7 million award from JEA (Jacksonville Electric Authority) in 2022, and additional public contracts with entities like Palm Beach County appear in public records as well. These are steady, large-ticket contract revenues that form the backbone of the business.
Rock Mining and Land Holdings
The quarrying side of the business, Youngquist Brothers Rock Inc., turned out to be the family's biggest wealth creator. Their Alico Road properties in Southwest Florida were sold to Martin Marietta in a deal that Gulfshore Business reported as a SWFL record at $620 million in October 2024. Brett Youngquist was quoted in that coverage, confirming the family's direct involvement. This is a verified, public-records-based transaction, not a rumor, and it fundamentally changes the scale of any net worth conversation about this family.
Philanthropy and the Family Foundation
The Youngquist Family Foundation is a documented nonprofit entity with total end-of-year assets of approximately $9.25 million according to its most recent IRS Form 990-PF filing (filed July 8, 2025, as reported on ProPublica's Nonprofit Explorer). Foundations like this one are often used by wealthy families to manage charitable giving in a tax-advantaged way. The existence and scale of the foundation is itself a signal of the family's broader wealth, since private foundations require meaningful asset endowments to establish and maintain.
Assets, Investments, and Lifestyle Clues That Inform the Estimates
The Youngquist brothers are private individuals who have not sought public profiles, so lifestyle signals are limited but the business footprint speaks clearly. Here are the documented or reasonably inferred asset categories that net worth estimators would include:
- Real estate: The Alico Road quarry land alone transacted at $620 million. The family likely retains other Southwest Florida property, given their decades of operations in Lee County.
- Business equity: Youngquist Brothers Inc. as an ongoing drilling contractor with roughly $35 million in estimated annual revenue carries meaningful equity value independent of the land sale.
- Foundation assets: The Youngquist Family Foundation holds approximately $9.25 million in book-value assets, which is a floor indicator only, not a ceiling on family wealth.
- Cash and investments: Post-sale liquidity from the Martin Marietta deal, after taxes and transaction costs, would likely represent the largest single cash position in the family's financial picture.
- Equipment and operational assets: A drilling and construction contractor of this scale owns heavy equipment, vehicles, and infrastructure with significant depreciated but real value.
What is notably absent from public records is any confirmed real estate portfolio outside of the business context, publicly reported luxury purchases, or stock holdings that would be disclosed through SEC filings. The Youngquists appear to run a tight-lipped private operation, which is common among generational family businesses in the construction and resource extraction sectors.
How Their Wealth Has Likely Grown Over Time
The Youngquist family's financial trajectory falls into fairly clear phases. From 1971 through the 1990s, the brothers were building the business from scratch, establishing market dominance in Florida's deep injection well niche. Incorporating in 1977 and expanding into quarrying over the following decades created a dual-income model that compounded steadily.
Through the 2000s and 2010s, consistent government contracting kept revenue flowing. Florida's infrastructure needs, particularly around environmental compliance and water management, kept demand for Class I injection wells strong. The rock mining operations, meanwhile, were sitting on appreciating Southwest Florida land that was becoming increasingly valuable as the region grew.
The real inflection point is 2024. The $620 million Martin Marietta sale represents a liquidity event that likely exceeds the cumulative profits of the prior five decades of operations. For context, deals of this scale in SWFL's real estate market are genuinely unprecedented, which is why it was flagged as a regional record. If the family retains a significant portion of those proceeds after taxes (federal capital gains plus Florida has no state income tax, which helps), the net worth picture post-2024 is dramatically different from anything published before that transaction closed.
How to Verify and Update These Estimates Yourself
Because the Youngquist brothers are private individuals running private companies, you will not find a perfectly clean answer in one place. But you can build a reasonably confident picture using legitimate public sources. Here is how to approach it:
- Start with Florida corporate records at Sunbiz (the Florida Division of Corporations), which lists official entity filings, registered agents, and officers for Youngquist Brothers LLC (Filing ID: L21000000723) and any related entities. This confirms who is legally tied to the business.
- Cross-reference with MSHA's mine safety database to verify the quarrying operation's controllers and active status. This is a federal government primary source, not an aggregator.
- Check ProPublica's Nonprofit Explorer for the most recent Youngquist Family Foundation Form 990-PF. This gives you audited asset data that is as close to a verified financial disclosure as you will get for this family.
- Search public procurement databases and government meeting minutes for recent contract awards naming Youngquist Brothers. JEA and Palm Beach County records are already documented; other Florida municipalities may have similar records.
- For the Martin Marietta land deal, verify through public property records in Lee County, Florida, not just news coverage. Deed transfers and recorded sale prices are public record in Florida.
- For any SEC-related claims (like the Schedule 13G Reddit reference), go directly to SEC EDGAR and search for filings by name. Do not rely on Reddit or secondary aggregators for investment disclosure information.
- Treat revenue estimates from sites like Growjo as rough directional signals only. They use employee count and industry benchmarks to model revenue, not actual financials.
Red Flags to Watch For
- Any net worth figure for the Youngquist brothers that was published before late 2024 will almost certainly miss the Martin Marietta deal entirely, making it dramatically understated.
- Watch for confusion between Harvey Youngquist Sr. and Harvey B. Youngquist Jr., or between Tim Youngquist the co-founder and any other individuals with that name in public records.
- Sites that quote a single precise number (e.g., '$450,000,000 exactly') without citing methodology are fabricating false precision. Always look for a range and an explanation.
- Aggregator sites that blend family-level wealth with individual net worth without clarifying whether the figure covers one person or multiple family members are a common source of confusion.
- Foundation asset values ($9.25 million) are not net worth. The foundation is a charitable entity with its own legal structure separate from personal finances.
Putting It All Together
The Youngquist brothers are a fascinating example of generational, regional wealth built through consistent execution in a specialized industrial niche rather than celebrity or public market exposure. If you want a quick snapshot of their overall wealth, the following sections summarize the most defensible estimate of the Youngquist brothers' net worth. They are not household names, which is exactly why net worth estimates for them are so scarce and inconsistent. If you want a headline-style number, you will typically need to piece together multiple sources to approximate Kix Brooks and Dunn’s net worth and deal-by-deal earnings net worth estimates for them are so scarce and inconsistent. The $620 million Martin Marietta land deal in 2024 is the single most important data point for any post-2024 estimate, and it is verifiable through public records. Combined with ongoing contracting revenue, business equity, and foundation assets, the most defensible estimate for the Youngquist family collectively sits in the $300 million to $600 million range as of May 2026, though the full picture depends heavily on how deal proceeds were structured, distributed, and reinvested. If you are looking for the Weston Kieschnick net worth angle, the same 2024 liquidity and contracting revenue are usually what drive the estimates Youngquist family collectively. Anyone seriously researching this topic should treat any figure without a sourcing explanation as a placeholder, not a fact. The methodology matters as much as the number itself, which is something worth keeping in mind when comparing net worth pages across any database, whether you are looking at business figures like the Youngquists or entertainment families with similarly complex wealth structures. For readers who are specifically comparing figures for the Kaulitz brothers net worth, the same sourcing caution applies when reported totals are based on limited public data net worth pages. If you are specifically trying to nail down the kix brooks net worth number, use the same approach of checking verifiable sources and avoiding unsourced rounding.
FAQ
Is the “Youngquist brothers net worth” number per brother or for the family collectively?
Treat “youngquist brothers net worth” as a family estimate, not a per-person number. The most defensible approach is to start from the 2024 transaction value, then adjust for ownership splits between Harvey and Tim, taxes and transaction costs, and any reinvestment into the drilling and quarrying subsidiaries. Without that ownership breakdown, per-person figures are usually guesswork.
Why can the $620 million sale lead to lower net worth estimates than expected?
Use the Martin Marietta sale as a reference point, then avoid assuming the full $620 million became liquid personal wealth. Sale proceeds often route through operating companies, repay debt, fund replacement properties, and cover capital gains tax and closing costs. Net worth could be meaningfully lower than the gross headline price depending on deal structure.
How can I verify that the “Tim Youngquist” in public records is actually the same person from the Youngquist Brothers companies?
Look for direct indicators of ownership, like officer/principal names in corporate filings, MSHA-controlled roles, and any trust or entity holding statements tied to a specific person. A common mistake is to treat a similarly named individual in SEC or other databases as automatically the same Tim Youngquist without verifying identity.
Why do different net worth websites produce dramatically different numbers for the Youngquist brothers?
Net worth estimators differ mainly because they pick different profit margins and debt levels to convert revenue into equity value. For a private contractor and quarrying business, one site may assume high margins and low leverage, while another assumes the opposite. That is why two pages can differ by hundreds of millions even when they reference the same revenue number.
How should I judge whether a specific “Youngquist brothers net worth” figure is trustworthy?
If you see a precise rounded figure with no explanation, treat it as a placeholder. A practical rule is to only weight numbers that either (1) connect to a specific verifiable transaction, or (2) show the underlying assumptions (margins, leverage, ownership percentage).
What is the best way to know whether an estimate reflects the post-2024 reality?
Check for post-2024 updates tied to the sale, not just legacy estimates last refreshed before the transaction. Because the biggest wealth event closed in 2024, any “as of” date that predates that deal is likely structurally outdated.
Can the Youngquist Family Foundation assets be used as a direct proxy for the family’s total net worth?
Yes, sometimes. Foundations with publicly filed IRS forms can confirm certain assets exist, but they do not automatically tell you how much of the family’s total wealth is outside the foundation. A separate step is to avoid double-counting foundation assets if a site blends nonprofit endowment values into total family net worth.
Why is using revenue alone usually a weak method for estimating net worth for private companies like this?
Because the companies are private, there is often limited disclosure about stock holdings, executive compensation, and personal liquidity. Estimators can also miss illiquid assets, like mineral rights or long-term land holdings, and over-rely on business revenue. The most robust approach is a transaction-based anchor plus business equity reasoning, not revenue alone.
Is it fair to compare the Youngquist brothers’ net worth to celebrity net worth numbers?
If you are comparing “youngquist brothers net worth” to other figures, keep methodology consistent. Entertainment net worth pages often use different data sources (public earnings, endorsements, and listed assets) than private industrial founders. Comparing raw totals without accounting for sourcing differences can be misleading.
What’s a practical step-by-step method to build my own “Youngquist brothers net worth” estimate?
Start with a simple checklist: (1) confirm the 2024 sale details, (2) estimate how proceeds could be split across taxes, debt, and reinvestment, (3) assess whether ownership is concentrated or spread via entities and trusts, and (4) sanity-check against any verifiable contract scale and business assets. This reduces the risk of over-weighting one assumption.
