Charles Sukup Net Worth 2026: Estimate, Assets & Timeline

As of July 14, 2026, Charles Sukup's net worth is estimated in the range of $150 million to $350 million, with a moderate-to-low confidence level given that Sukup Manufacturing Co. is a private, family-owned company with no public financial disclosures. That wide range reflects genuine uncertainty, not guesswork, there are simply no audited statements, SEC filings, or disclosed equity splits to anchor a tighter number. What we do know is that Charles has spent decades at the helm of what the company itself calls the world's largest family-owned, full-line grain-system manufacturer, and that kind of institutional position in a capital-intensive agricultural industry typically corresponds to substantial accumulated wealth.

Top-Line Estimate and Key Takeaways

The estimate above, $150M to $350M, is derived from a combination of private-company revenue modeling, comparable-company valuation multiples, and reasonable assumptions about family equity distribution. Because Sukup Manufacturing is entirely private and Iowa-incorporated, none of these figures come from a balance sheet you can look up. They are informed estimates, and I want to be upfront about that from the start.

• Estimated net worth range (July 14, 2026): $150 million – $350 million
• Confidence level: Low-to-moderate (private company, no public financials, no disclosed equity split)
• Primary wealth source: Ownership stake in Sukup Manufacturing Co., Sheffield, Iowa
• Charles served as President from 1995 to approximately 2020, then transitioned to Chairman of the Board
• Sukup Manufacturing employs 800+ people worldwide as of 2025 and has more than 80 U.S. patents
• No verified salary, dividend, or income figures are publicly available
• The family as a whole likely controls 100% of equity; Charles's individual share is unknown

Net Worth Snapshot: Assets, Liabilities, and Income

Because Sukup Manufacturing is a private family company, there is no itemized public record of Charles Sukup's personal balance sheet. What follows is a structured estimate built from available data points, private-company revenue ranges, standard industry valuation multiples, and reasonable assumptions about how wealth is typically distributed among founding-family members in similar businesses. Treat every figure here as an informed estimate, not a verified figure.

Annual income is equally difficult to pin down. Salary.com's private-company data compiler estimates Sukup Manufacturing's total revenue in the broad range of $50 million to $200 million. A company of that profile and workforce size (800+ employees, multiple production and distribution facilities, international operations) likely skews toward the higher end of that band or beyond it. Executive compensation at privately held family firms in the agricultural equipment sector can range from $500,000 to several million dollars annually for a chairman-level family member, though in practice many family owners take distributions rather than formal salary.

Business Interests and Ownership Stakes

Sukup Manufacturing Co. is the core and almost certainly the dominant asset. Founded in 1963 by Eugene and Mary Sukup in Sheffield, Iowa, the company grew from a single stirring-machine patent into a full-line grain handling and drying equipment manufacturer with more than 80 U.S. patents. It incorporated in Iowa on May 25, 1965. Charles E. Sukup appears in state filing records as an officer (listed as Treasurer in some extracts), and the business-entity records confirm that the company remains entirely family-controlled, with no external shareholders or public listings on record.

In 2015, Sukup Manufacturing expanded internationally by acquiring a controlling interest, reported as approximately two-thirds, in Danish company DanCorn, which was subsequently branded Sukup Europe A/S. This acquisition marked the company's most significant international move and added European distribution and manufacturing capacity. The value of that stake is not publicly disclosed, but it meaningfully expands the enterprise's footprint and, by extension, the Sukup family's collective asset base.

Beyond the core manufacturing business, there is no public evidence of Charles Sukup holding significant independent business interests separate from Sukup Manufacturing. It is common for family business leaders in his position to hold personal investments in regional real estate, agricultural land, or financial accounts, but none of these are documented in public records. The company's trademark filings as recently as 2024 (including the SYNK mark) confirm continued active corporate IP development under the Sukup Manufacturing name. USPTO-reporting mirror records show the 2024 SYNK trademark application listing Sukup Manufacturing Co. as the owner and filing entity (SYNK, trademark application (owner: Sukup Manufacturing Co.), USPTO reporting mirror) SYNK trademark application (2024).

Earnings Breakdown: Where the Money Comes From

For a family company of Sukup Manufacturing's size and structure, the primary wealth-generation mechanism is not a W-2 salary, it is ownership value and profit distributions. When a family controls 100% of a profitable manufacturing company, the economics work differently than for a salaried executive at a public firm. The owners decide how much to reinvest in the business and how much to distribute to themselves. Given the company's consistent expansion (new product lines, international acquisitions, headcount growth from roughly 600 to 800+ employees), it is reasonable to assume a significant portion of profits have been reinvested rather than distributed, which would mean Charles's liquid income is lower than the raw enterprise value might suggest.

Career and Financial Timeline

Charles Sukup's wealth trajectory tracks almost entirely with the growth of Sukup Manufacturing under his leadership. Here is how the key milestones line up.

1. 1963: Eugene and Mary Sukup found Sukup Manufacturing Co. in Sheffield, Iowa, with the invention of the Stirway stirring machine — the foundation of the family's eventual fortune.
2. 1965: Sukup Manufacturing formally incorporates as an Iowa corporation (May 25, 1965).
3. Pre-1995: Charles Sukup, holding degrees in agricultural engineering from Iowa State University, works in engineering and sales roles within the company, building operational expertise before any formal leadership title.
4. 1995: Charles assumes the Presidency of Sukup Manufacturing, with founder Eugene Sukup remaining as Chairman — a structured generational transition that positioned Charles as the primary day-to-day leader.
5. 1998: Sukup launches portable continuous-flow dryers, expanding the product line and revenue base under Charles's presidency.
6. 2001: Sukup enters grain bin manufacturing, a major product-line expansion that significantly broadened the company's addressable market.
7. 2015: Sukup Manufacturing acquires a reported two-thirds controlling interest in DanCorn (rebranded Sukup Europe A/S), marking the company's first major international acquisition and adding European scale.
8. 2018: Founder Eugene Sukup passes away in July at age 89; Charles and brother Steve Sukup continue as the family's senior leadership pair.
9. 2020: Generational leadership shift — Steve Sukup becomes President & CEO while Charles transitions to Chairman of the Board, an 'ambassador' role focused on strategic oversight and company legacy.
10. 2025: Company milestone reporting cites 800+ employees worldwide and multiple production and distribution facilities, reflecting continued growth under the post-2020 structure.
11. 2026: Charles remains Chairman; accumulated ownership value and decades of reinvested profits represent the core of his estimated $150M–$350M net worth.

Major Financial Events and Transactions

There are four financial events that stand out as the most significant wealth-shaping moments in Charles Sukup's career. None involved a public market, an IPO, or a disclosed transaction price, which is part of what makes estimating his net worth difficult.

Succession to the Presidency (1995)

When Charles took the presidency from Eugene in 1995, he assumed both the operational leadership and, implicitly, a larger stake in the company's future value creation. The 32 years of growth under Eugene had already built a credible regional manufacturing business; Charles's presidency presided over the expansion into full-line grain systems, international markets, and a workforce that grew substantially. The value of that presidency was not a transaction, it was the accumulation of equity value over time.

DanCorn / Sukup Europe Acquisition (2015)

The acquisition of a two-thirds stake in Denmark-based DanCorn in 2015 was the company's largest disclosed international transaction. No purchase price was made public, but an acquisition of a controlling interest in a European agricultural equipment company suggests a transaction value likely in the tens of millions of dollars. This deal added European production capacity, distribution, and brand presence under the Sukup Europe A/S name, expanding the enterprise's total addressable market.

Leadership Transition and Inheritance of Founder's Estate (2018–2020)

Eugene Sukup's death in July 2018 at age 89 triggered an estate process within the founding family. The distribution of Eugene's ownership stake among family members, including sons Charles and Steve, likely had significant implications for each sibling's individual equity position. Because Iowa probate records for private business interests are not required to be disclosed publicly, the specifics remain unknown. The subsequent 2020 transition, Steve to President & CEO, Charles to Chairman, formalized the division of responsibilities that likely accompanied any estate settlement. Family Business Magazine, Family Business CEOs to Watch 2021 reports that in 2020 Steve Sukup became President & CEO while Charles Sukup moved to chairman of the board Family Business Magazine — Family Business CEOs to Watch 2021.

Continued IP and Product Investment (2024 and Beyond)

Trademark filings as recently as 2024 (including the SYNK application) and the company's stated portfolio of more than 80 U.S. patents suggest ongoing investment in proprietary product development. For a private company, IP investment of this scale is a meaningful contributor to enterprise value and, therefore, to the wealth of the owning family.

How I Calculated the Estimate

Let me walk through the methodology directly, because transparency here matters more than a confident-sounding number.

Step one was estimating revenue. Salary.com's private-company data puts Sukup Manufacturing in a $50M–$200M revenue band with 500–1,000 employees. The Hampton Chronicle's 2025 reporting on 800+ worldwide employees and multiple production facilities, combined with the company's international footprint and full-line product range, suggests the actual revenue is likely at or above the top of that band, my working estimate is $150M–$250M in annual revenue, though this is not verified.

Step two was applying an EBITDA margin and valuation multiple typical for privately held agricultural equipment manufacturers. Companies in this segment generally trade at 5x–8x EBITDA in private transactions, with EBITDA margins often in the 10%–18% range. At $200M revenue with a 12% EBITDA margin and a 6x multiple, that yields a rough enterprise value of approximately $144 million. At the higher end ($250M revenue, 15% margin, 7x multiple), the enterprise value approaches $262 million. I used a central estimate of roughly $200M–$250M enterprise value as the basis for the ownership calculation.

Step three was estimating Charles's equity share. With Eugene's estate divided between at minimum Charles and Steve (and potentially other family members or trusts), and given that Charles held the presidency for 25 years, a working assumption of 30%–50% ownership is reasonable but entirely unverified. Applying that range to a $200M–$250M enterprise value yields an ownership stake value of $60M–$125M at the low end and higher if the enterprise value is larger. Adding estimated personal assets (real estate, investments) and recognizing the possibility that the enterprise is worth considerably more than my conservative model suggests, I arrived at a net worth range of $150M–$350M.

This is an analytically constructed estimate, not a verified figure. Every assumption in that chain, revenue, margins, multiples, equity share, could be materially wrong in either direction.

Confidence Level, Uncertainty, and Where This Estimate Could Be Wrong

I rate confidence in this estimate as low-to-moderate, and I want to explain specifically where the biggest risks are.

Where the estimate is most likely too low

If Sukup Manufacturing's actual revenue is materially higher than the Salary.com band suggests, which is plausible given the company's 800+ employee count, international operations, and 60-plus year operating history, then both the enterprise value and Charles's share would be higher. Agricultural equipment companies with global distribution and a dominant niche position often command premium multiples. If the true enterprise value is $400M–$500M and Charles holds a 40% stake, his net worth would be in the $160M–$200M range from that stake alone, plus other assets. Some industry observers would put the total family wealth (not just Charles's share) well above $500M.

Where the estimate is most likely too high

The estimate could be too high if Charles's equity share is smaller than assumed, perhaps Eugene's estate was distributed across a larger set of beneficiaries, or Charles's formal ownership position was reduced as part of the 2020 transition to Steve's leadership. It is also possible that the company carries significant debt from the DanCorn acquisition or other capital investments that reduces net equity value. Without any audited financials, there is no way to check for leverage the company may carry.

What could change this estimate going forward

• A sale or partial sale of Sukup Manufacturing to a private equity firm or strategic buyer would be the single largest potential event — even a minority stake sale would reveal enterprise value and likely generate a significant liquidity event for Charles
• Any public disclosure of financials (e.g., through a bond offering or regulatory filing) would dramatically improve estimate precision
• Changes in agricultural commodity cycles affect grain equipment demand and, therefore, Sukup's revenue and profitability
• Estate or trust restructuring following Eugene Sukup's 2018 death could shift equity percentages among family members
• Expansion or contraction of the Sukup Europe A/S operation would affect the international portion of the enterprise value

How to read this range as a casual reader

Think of the $150M–$350M range less as a precise answer and more as a credible bracket. The floor of $150M reflects a conservative scenario where the company is smaller than it appears and Charles's equity share is modest. The ceiling of $350M reflects a scenario where the company's revenue is at or above the top of analyst estimates and Charles retains a significant ownership share. The most likely single-point estimate, if I had to pick one, is somewhere around $200M–$250M, but I would hold that loosely. This is genuinely one of those profiles where the honest answer is 'we don't know, and here's why.'

How Charles Sukup Compares to Other Notable 'Charles' Wealth Profiles

For readers exploring wealth patterns across different industries and backgrounds, it helps to put Charles Sukup's estimated range in context alongside other notable figures named Charles. This site profiles a range of them, from business leaders to entertainment and sports figures, and the differences in how wealth is built are often as interesting as the numbers themselves. See the jean charles skarbowsky net worth profile for a contrasting example of wealth built in combat sports. For a comparison in a different market, see Charles Curran (Sydney) net worth for an Australian entrepreneurial wealth profile.

What distinguishes Charles Sukup's wealth profile from many others featured on this site is the concentration and illiquidity of the asset base. Virtually all of his estimated wealth sits in a single private company with no public market for shares. That means he is almost certainly less liquid than his net worth figure implies, you cannot simply sell 10% of Sukup Manufacturing on a Tuesday afternoon. For business-wealth profiles like this one, the net worth figure is better understood as 'what he would be worth if the company were sold today' rather than 'cash and assets he can access readily. For additional context on similarly named individuals and how privately held business ownership affects estimations, see the profile on Charles Soderstrom net worth. ' That distinction matters when comparing him to, say, a celebrity or athlete whose wealth is held in more liquid forms.

A Note on Sources and What Is Missing

The sources underpinning this profile are: Sukup Manufacturing's own company history and website materials; Eugene Sukup's obituary from the Des Moines Register and Legacy; congressional witness biography for Steve Sukup (which describes the 2020 leadership transition); Family Business Magazine's 2021 coverage; Hampton Chronicle's 2025 local profile citing employee and facility counts; Iowa Secretary of State business-entity records (which list officers but not equity percentages); BBB business profile data; USPTO trademark-filing records; Salary.com's private-company revenue estimate; and Danish agricultural industry profiles noting the 2015 DanCorn acquisition.

What is missing, and what would be needed to substantially tighten this estimate, is any of the following: audited financial statements, a disclosed ownership structure, any public statement by the Sukup family about equity distribution, or a transaction (sale, refinancing, bond issuance) that would require financial disclosure. None of those exist in publicly accessible form as of July 14, 2026. Sukup Manufacturing has no SEC filings, no publicly traded debt, and no requirement to disclose revenue or profits as an Iowa private company. That is not unusual for a family business of this type, it simply means estimates like this one carry inherent uncertainty that cannot be resolved without insider information.
