Confirming which William Morean you mean
There is really only one William Morean who comes up consistently in financial and corporate research: William D. Morean, the longtime Chairman of Jabil Circuit (now Jabil Inc.), headquartered in St. Petersburg, Florida. Born in 1955 or 1956 depending on the source, he is the son of Bill Morean, one of Jabil's co-founders. William D. joined Jabil in 1977, became a board director in 1978, and served as CEO from 1988 to September 2000. He has remained Chairman of the Board since 1988. If you were searching for a different William Morean, such as a local business figure, an athlete, or someone in entertainment, the public record does not surface a financially notable person by that name at a comparable scale. The person this article covers is unambiguously the Jabil Circuit executive.
His identity is well-documented across multiple public record systems. UK Companies House lists a William MOREAN, born September 1955, with a correspondence address at 618 Pinta Drive, Tierra Verde, Florida 33715, who served as a director of Jabil Circuit Limited (a UK-registered subsidiary) from December 1992 to July 2000. SEC EDGAR filings reference "MOREAN WILLIAM D." in connection with Jabil Circuit Inc. (ticker: JBL). ProPublica's Nonprofit Explorer also identifies him as a director of the Morean Family Foundation, a publicly registered nonprofit (EIN 59-3712705). These cross-references make it straightforward to confirm you have the right person.
The short answer on his net worth
The most defensible estimate for William D. Morean's net worth today is somewhere in the range of $200 million to $1.1 billion, with the wide spread reflecting how dramatically different methodologies and time periods produce different numbers. Here is a quick breakdown of the major published figures:
| Source | Estimate | Basis | Date |
|---|
| Forbes 400 | $1.0 billion | Jabil Circuit equity and wealth accumulation | 2005 |
| Forbes World's Billionaires | $1.0 billion | Publicly traded Jabil Circuit stake | 2007 |
| Benzinga | $242 million | Reported Jabil shares (insider filings) | Recalculated Nov 2024 |
| TipRanks | Implied ~$700M–$1B+ | 11.28 million Jabil shares held | As of filing date |
| CoreStreet | At least $1.4 million | SEC Form 4 sale history + current holdings | Dec 2025 |
| GuruFocus | At least $0 | Final shares after Form 4 transactions | Mar 2026 |
The Forbes figures from 2005 and 2007 are the most comprehensive and widely cited, both landing at $1.0 billion. They account for total wealth, not just one asset class. The Benzinga figure of $242 million is more recent and is based specifically on his reported Jabil share position, which means it excludes any private assets, real estate, cash, or other holdings. The CoreStreet and GuruFocus numbers are essentially floor estimates built purely from SEC transaction data, and should be read as "minimum documented equity" rather than anything close to total net worth. A reasonable working estimate for 2026 is somewhere between $250 million and $1 billion, leaning toward the lower end of that range given Jabil's share price fluctuations and the time elapsed since the 2005–2007 peak valuations.
How net worth is actually estimated
Net worth is assets minus liabilities. For a public company insider like William D. Morean, the most trackable asset is his equity stake in Jabil Inc. TipRanks reports he holds approximately 11.28 million shares of Jabil Circuit (JBL). At various points in 2024 and 2025, JBL traded between roughly $90 and $140 per share, which puts the value of that block alone somewhere between $1 billion and $1.6 billion on paper before taxes, though insider stakes are often subject to lock-up agreements, diversification constraints, and tax considerations that significantly reduce the realized value.
Beyond publicly traded shares, net worth researchers look at several other asset categories. For someone in Morean's position, these would include private investment vehicles (SEC Form 4 filings reference "Cheyenne Holdings Limited Partnership," for which he is the sole general partner), real estate holdings, private equity or venture investments, and assets held through family structures like the Morean Family Foundation. On the liability side, mortgages, margin loans against equity positions, and any business-related debt would reduce the gross figure. None of these are publicly disclosed in full, which is why every published net worth figure for him is an estimate.
The original wealth-building event is well-documented: Forbes reports that Morean bought a 51% stake in Jabil Circuit for $100,000 and then took the company public in 1993. That IPO, combined with Jabil's explosive growth as an electronics manufacturing services provider, is what vaulted him onto the Forbes 400 list by 2005. His tenure as CEO ended in 2000, but he retained the Chairman role and his equity stake, which continued to compound as Jabil expanded globally.
Why different websites show such different numbers
The variation you see across sources is not a mistake. It reflects genuinely different methodologies and data cutoffs. Sites like Forbes dedicate research teams to building holistic wealth profiles that include interviews, industry intelligence, and asset-by-asset estimation. Their $1.0 billion figure for Morean in 2005 and 2007 reflects that comprehensive approach. By contrast, insider-trade tracking tools like Benzinga, CoreStreet, and GuruFocus are essentially parsing SEC Form 4 filings, which only capture transactions in publicly registered securities. They see what shares were bought or sold and when, and they calculate a position value from that. If Morean has diversified into private assets over the past 15 years, those tools will never capture it.
There is also the data freshness issue. Benzinga explicitly states its estimate was recalculated as of November 4, 2024. GuruFocus flags that its figure as of March 13, 2026 assumes no transactions after a certain date, and openly states the estimate "may not reflect actual net worth." CoreStreet gives a minimum figure as of December 13, 2025. Each site is working with a different snapshot. When JBL shares are up, equity-based estimates rise. When shares fall, those estimates drop. But a Forbes-style holistic estimate would also factor in the private wealth that doesn't move with the stock price on a daily basis. This is why you should never rely on a single figure from a single site, a point that financial researchers have made repeatedly when examining how net worth sites operate.
It is also worth noting that some net worth aggregator sites simply copy or extrapolate from older Forbes entries without updating their methodology, which is why you may still see $1.0 billion cited on celebrity net worth sites that have not re-researched the figure since 2007. For a figure as specific and complex as a major company chairman's net worth, that kind of stale-data copying is common and worth being skeptical about.
How to check and sanity-test these numbers yourself
The most reliable primary source for any public company insider is SEC EDGAR. You can search for "Morean William D" at sec.gov to pull up all Form 4 filings associated with him and Jabil Circuit. Form 4 filings are required whenever an insider buys or sells shares, so they give you a real-time picture of reported transactions. DEF 14A proxy filings from Jabil also include beneficial ownership tables that list his total shares at a specific measurement date, including shares held through entities like Cheyenne Holdings Limited Partnership. A 2004 DEF 14A, for example, listed approximately 20,493 shares directly attributed to him in a beneficial ownership context, separate from larger block holdings.
For a secondary cross-check, Jabil's annual reports (10-K filings) include director biographical information and any material agreements. A 2017 10-K references an Agreement and General Release dated June 12, 2017 between Jabil Inc. and William D., which shows up in EDGAR and confirms his continued documented relationship with the company beyond his CEO tenure. The Jabil 2006 Annual Report includes a full biography confirming his roles and tenure dates. Cross-referencing these primary documents against what third-party sites report is the most reliable sanity-test available to a public researcher.
Real estate can sometimes be checked through county property records. Given his known address in Tierra Verde, Florida (a coastal community near St. Petersburg), Pinellas County property records are publicly accessible and can give a floor figure for real estate holdings in that area. This won't capture properties held in trusts or LLCs, but it is a useful starting point.
Income and asset drivers worth watching
For someone like William D. Morean, the big wealth drivers are fairly clear even if the exact numbers are not. As Chairman of Jabil's board, he receives director compensation, which for major S&P 500 company boards typically includes a combination of cash retainer, equity awards, and meeting fees. Jabil's proxy statements (DEF 14A filings on EDGAR) will include the director compensation table each year, making this one of the most transparent components of his income.
His continuing equity stake in JBL is the dominant variable. Jabil has grown significantly since its 1993 IPO and has been a consistent performer in the electronics manufacturing services sector. Any large share sales by Morean would appear in Form 4 filings within two business days of the transaction. Watching those filings is the most direct way to track changes in his equity-based wealth. His investment partnership, Cheyenne Holdings Limited Partnership, is another vehicle worth monitoring if it appears in any SEC filings or state records, as it may hold shares or other assets separately from his direct holdings.
Philanthropy is also a relevant signal. The Morean Family Foundation (EIN 59-3712705, listed on ProPublica's Nonprofit Explorer) files Form 990 returns annually with the IRS. Those filings disclose assets, grants made, and officer compensation, and they can give a sense of the foundation's scale relative to the family's overall wealth. Large charitable gifts often appear in 990 filings before they show up anywhere else in public records.
What these estimates can and cannot tell you
Every number published about William D. Morean's net worth is an estimate derived from incomplete public data, and it is worth being explicit about what that means. No published figure has been audited or verified by an independent accountant. Forbes' methodology, while the most comprehensive publicly available, still relies on assumptions about private assets, debt levels, and asset values that are not publicly disclosed. The insider-trade-based figures from Benzinga, CoreStreet, and GuruFocus are even narrower: they are essentially calculating the market value of a known share position at a point in time, which is a subset of total wealth.
To update any estimate over time, the most practical approach is a three-step process. First, check the current JBL share price and multiply it by the most recently reported share count from SEC Form 4 or DEF 14A filings to get an equity floor. Second, add any publicly documented real estate, foundation assets, or other disclosed holdings. Third, apply a reasonable discount for taxes, diversification assumptions, and the possibility that private liabilities offset some of the gross figure. This gives you a defensible range rather than a false-precision single number, which is the honest way to present any net worth estimate for a private individual.
It is also useful to keep some context in mind. Morean's wealth profile is fairly concentrated in a single company, which means his net worth is more volatile than someone who has fully diversified. Comparing him to peers in the electronics manufacturing sector or to other major company founders who retained significant equity stakes can help calibrate whether a given estimate seems high or low. For example, looking at how another high-profile figure's net worth is constructed from similar public data sources can highlight the shared limitations of these estimates.
The bottom line is that William D. Morean's net worth is best described as a range: roughly $250 million to $1 billion in 2026, anchored by his Jabil equity stake and shaped by unknown private holdings and liabilities. The Forbes peak figure of $1.0 billion from 2005 and 2007 remains a useful benchmark for understanding the scale of wealth he built, even if the current figure has shifted with the passage of time and market changes. Anyone doing serious research should start with SEC EDGAR Form 4 filings and Jabil's annual proxy statements, treat third-party aggregator figures as directional rather than definitive, and revisit the estimate annually as new filings become available. That approach will always give you a more accurate picture than any single cached number on a net worth listing site. For additional context on how these kinds of estimates are built for entertainment-industry figures, seeing how a celebrity's net worth is calculated from comparable public data is a good parallel to review.
