François Locoh-Donou's net worth is most credibly estimated in the range of $57 million to $81 million as of mid-2026, based on his publicly disclosed insider holdings in F5, Inc. (ticker: FFIV). The widest figure you'll see floating around is roughly $80.9 million (QuiverQuant, April 2026), while more conservative trackers put it closer to $52 million to $57 million depending on when FFIV's share price was sampled. None of these numbers are a complete picture of his wealth since they only count publicly reported share positions, not salary, bonuses, private investments, or his co-founding stake in Cajou Espoir. But for a publicly verifiable baseline, $57 million to $81 million is the most honest range you can stand behind today. François Nars net worth searches usually point back to share-based estimates like these and the latest SEC filings that underpin them.
François Locoh Donou Net Worth: What’s Known, Verified Range
Who François Locoh-Donou is and why people search his net worth
François Locoh-Donou (also spelled Francoïs Locoh-Donou or, in SEC filings, Locoh-Donou Francois) is the Chairman, President, and CEO of F5, Inc., a publicly traded application security and multi-cloud networking company listed on Nasdaq under FFIV. He joined F5 in April 2017 as President, CEO, and Director, and was appointed Chairman of the Board in March 2026 following an announcement the previous October. That combination of roles at a large-cap tech company puts him in the category of executives whose compensation and insider share transactions are subject to mandatory SEC disclosure, which is exactly why aggregator sites can produce a net worth figure for him at all. François Olivennes net worth is often discussed in articles that break down how insider filings and stock performance influence executive wealth net worth figure.
Before the tech-executive chapter, Locoh-Donou built a career in telecom and networking at Ciena Corporation, where he spent roughly 14 years rising to Chief Operating Officer. He is also Togolese, and a Forbes profile from 2013 described him as a social entrepreneur tied to Cajou Espoir, a cashew processing company he co-founded in Togo in 2004 alongside Maurice Edorh. Cajou Espoir now employs more than 900 people and operates factories in Tchamba and Blitta. Most people searching his name are primarily curious about the F5 side of the equation since that is where the publicly verifiable money lives, but the private entrepreneurial dimension is real and worth noting. If you are specifically looking for Francois Arnaud net worth, most estimates online are ultimately tracing the same type of SEC insider holdings and compensation disclosures.
How to estimate net worth for public figures (and what sources to trust)
For publicly traded company insiders, net worth estimates are almost always built from one foundation: SEC Form 4 filings. When a corporate officer, director, or 10-percent owner buys or sells shares, they have to report it to the SEC within two business days. That creates a running record of how many shares they hold. Aggregator sites like QuiverQuant, Benzinga, MarketScreener, and Insidertrades.com then take the disclosed share count, multiply it by the current (or a recent) stock price, and call that a net worth estimate. It is a reasonable proxy, but it is not a complete picture.
The most trustworthy inputs are, in descending order of reliability: (1) SEC Form 4 filings directly from the SEC's EDGAR system, (2) proxy statements (DEF 14A filings) which disclose annual compensation including salary, bonus, and equity grants, and (3) secondary aggregators that clearly cite which filing and which date they used to produce their number. When a site does not tell you the valuation date or the share count behind its estimate, treat the number as directional at best. François Locoh-Donou has over 220 SEC filings on record under CIK 1526624, so there is no shortage of primary data to cross-reference.
François Locoh-Donou's net worth: what's publicly known vs what's uncertain
Here is where things get more granular. The spread across trackers is wide enough to be worth explaining rather than just averaging. Each figure below is share-based and tied to a specific snapshot date.
| Source | Estimate | Valuation Date / Basis |
|---|---|---|
| QuiverQuant | At least $80.9 million | April 29, 2026 (FFIV insider share holdings) |
| Benzinga | $78.6 million | Recalculated May 9, 2026 (multiple company share positions) |
| MarketScreener | $57 million | March 30, 2026 (188,989 FFIV shares valued at ~$55M + other holdings) |
| Insidertrades.com | At least $52 million | May 5–10, 2026 (F5 share ownership only) |
The variation comes down to a few factors: which share classes or company positions are included, whether vested-but-unexercised options are counted, and which date FFIV's stock price is used. Benzinga explicitly lists positions across Capital One Financial, Ciena Corp., and F5, which explains why its figure is higher than sources counting only FFIV. None of these estimates account for private company holdings (like any stake in Cajou Espoir), real estate, cash, or other personal assets. That means the real number could reasonably be higher than any figure listed above. It could also be lower if leveraged positions or liabilities offset asset values, though there is no public evidence suggesting that is the case.
Career timeline and major wealth-building milestones
Understanding where the money comes from requires tracing the career. Locoh-Donou's wealth-building story has three distinct chapters: a long telecom apprenticeship, the Cajou Espoir founding, and the F5 leadership era where most of the publicly measurable wealth was generated.
- 2004: Co-founds Cajou Espoir in Togo with Maurice Edorh, a private cashew processing enterprise. Ownership stake and valuation are not publicly disclosed, but the company has scaled to 900+ employees and two factories, suggesting meaningful private equity value over two decades.
- Pre-2017 (Ciena Corporation): Spent approximately 14 years at Ciena, a publicly traded optical networking company, rising to Chief Operating Officer. Senior executive roles at public companies include salary, annual bonuses, and equity grants, all of which would have been disclosed in Ciena proxy statements. His listed position at Ciena appears in Benzinga's multi-company share tally.
- April 2017: Joins F5, Inc. as President, CEO, and Director. This is the single biggest wealth-building inflection point: a large-cap public company CEO role with substantial equity compensation.
- 2017–2025: Accumulates F5 equity through annual grants, vesting schedules, and open-market transactions reported in Form 4 filings. The compounding of equity over eight-plus years at a Nasdaq-listed tech company is the primary driver of the $52M–$81M share-based estimates.
- 2025 (compensation year): F5's DEF 14A filed January 26, 2026, discloses total compensation of approximately $23 million for Locoh-Donou for 2025. The bulk of executive pay at this level is equity-based, meaning it shows up as additional vested shares rather than cash.
- October 2025 / March 2026: F5 announces and then formalizes his appointment as Chairman of the Board. Adding the chair role to CEO responsibilities typically signals long-term tenure and continued equity accumulation.
Asset and income categories that typically shape net worth
For a public-company CEO of his tenure and compensation level, net worth is rarely a simple bank balance. It is a portfolio of interconnected asset classes, some easily visible and some completely opaque to outside observers. Here is how to think about each category for Locoh-Donou specifically.
- Public company shares (F5/FFIV): The most visible piece. Disclosed via Form 4. MarketScreener puts his FFIV holdings at roughly 188,989 shares valued at approximately $55 million as of late March 2026. FFIV's price fluctuations directly move this number day to day.
- Shares in other public companies (Ciena, Capital One): Benzinga's higher estimate includes positions in Ciena Corp. and Capital One Financial. These are likely legacy holdings from his Ciena tenure or board service and are disclosed in SEC filings.
- Annual compensation (salary, bonus, and equity grants): His 2025 compensation package was approximately $23 million per F5's proxy filing. At the CEO level, the majority of this is equity-based, which vests over time and adds to the share count above rather than arriving as liquid cash.
- Private company interest (Cajou Espoir): Co-founder and President of a private Togolese enterprise employing 900-plus people. No public valuation is available, but a 20-plus-year-old agribusiness of that scale in West Africa could represent meaningful equity, though liquidity is a separate question.
- Deferred compensation and retirement accounts: Standard for long-tenure executives. Not publicly visible but standard components of total wealth.
- Real estate and personal assets: No public disclosures. Common for executives at this compensation level but impossible to quantify from outside.
How to verify numbers and compare with similar public figures
If you want to check any of the figures listed above yourself, the chain of verification is straightforward. Start at the SEC's EDGAR full-text search system and search for CIK 1526624. You will find all of Locoh-Donou's Form 4 filings, which show every reported transaction. Count the current net shares held, multiply by FFIV's current price, and you have the same share-based estimate the aggregators produce. For compensation, pull F5's most recent DEF 14A (proxy statement) from EDGAR and look at the Summary Compensation Table. That will give you salary, bonus, stock awards, option awards, and other compensation broken out by year.
For context on how his wealth compares to similar figures, it helps to think in terms of career archetype. He is a long-tenure tech CEO at a mid-to-large-cap company, which typically puts net worth in the $50 million to $300 million range depending on stock performance and equity grant size. Entrepreneurs and executives covered in this site's database who combine a public-company leadership role with a private social enterprise, like some of the business leaders tracked under the François and Francisco name categories, tend to have harder-to-pin-down totals precisely because the private portion is invisible to aggregators. That is worth keeping in mind when you see figures with wide divergences, as you see here. If you are also looking up Olivier Francois net worth, the same method of checking primary filings versus third-party estimates applies.
Updating the estimate: how to check for new disclosures over time
Net worth estimates for public-company executives change every time their stock trades, every time they file a Form 4, and every time the company files a new proxy. For Locoh-Donou, there are a few specific triggers to watch for. Any significant purchase or sale of FFIV shares will show up as a Form 4 filing within two business days and will immediately shift the share-based estimate. F5's next annual proxy (DEF 14A) will disclose his 2026 compensation, typically filed in January 2027. If F5's stock price moves materially, the dollar value of his holdings shifts accordingly even without any new filing.
The most practical approach is to set up a free EDGAR email alert for CIK 1526624, which will notify you whenever a new filing is made under his insider record. Pair that with checking QuiverQuant or Benzinga's tracker pages every few months, since both sites update their estimates based on current share prices rather than the price at the time of the last transaction. If you see a sudden jump or drop in a third-party estimate, the first question to ask is whether it reflects a real transaction or just FFIV's stock moving. The filing will tell you which.
One final note on uncertainty: the $52 million to $81 million range you see across trackers today is not a sign that one source is wrong. If you are looking specifically for François Locoh-Donou net worth, the most defensible starting point is the SEC-based range and the valuation date used by each tracker. If you are specifically looking for Leonel Fransézze net worth, the same approach applies: compare what is publicly filed versus what cannot be verified from SEC disclosures leonel fransezze net worth. It reflects different methodologies applied to the same underlying SEC data at different moments in time. The honest answer is that his publicly verifiable wealth sits somewhere in that range as of May 2026, his private holdings are an unknown additive on top, and the total will shift as F5's stock moves and new compensation is disclosed. For a ballpark that you can actually defend, use the mid-range figure around $65 million to $70 million as a reasonable working estimate, and treat anything beyond that as speculation until new primary data surfaces. For a snapshot of that figure, you can also review the latest François Allaux net worth coverage and how it compares to the publicly disclosed range François Locoh-Donou net worth. Leonard Francois net worth interest typically stems from the same type of publicly disclosed filings and insider share tracking used for other tech executives.
FAQ
If the estimate keeps changing, does that mean François Locoh-Donou actually traded shares?
Because Form 4 disclosures are only filed when insiders trade, a person can hold the same shares for long periods and their “net worth” estimate still changes due to stock price movement. That means a higher or lower tracker number today does not always imply he bought or sold shares recently.
Why do different websites report different net worth totals for the same person?
Trackers sometimes include only certain positions, such as FFIV common stock, while others also aggregate additional disclosed accounts or related holdings. If you compare two sites, make sure they both state the same share class scope, otherwise you are comparing two different baskets of assets.
How can I tell whether a net worth estimate is using the right valuation date and share count?
If you are trying to validate a specific figure, do not rely only on “current price” multipliers. Check whether the estimate uses (a) the last reported share count, (b) the price on a stated valuation date, and (c) whether it counts options or only vested shares.
What parts of François Locoh-Donou’s wealth are SEC filings usually missing?
Form 4 filings reflect transactions, but they do not provide a full balance sheet. For example, they generally do not reveal cash savings, real estate, loans, or private venture stakes, so the SEC-based range is best treated as a floor or proxy, not a comprehensive net worth.
Do net worth estimates include vested options, or only shares that are actually owned?
Vested equity can be reported in different ways depending on how it is held, for instance directly owned shares versus vested-but-unexercised options. Some aggregators count more categories than others, which can widen the range even when the underlying filings are the same.
What should I use DEF 14A for, versus Form 4 filings, when estimating net worth?
Proxy statements (DEF 14A) disclose compensation, but they do not assign a cash value to every private asset or guarantee how much of equity was sold versus held. Use DEF 14A to understand compensation components, then use Form 4 to understand current holdings.
How do FFIV stock price swings affect his net worth estimate in practice?
Yes, large market moves can swing the dollar value quickly even without any insider transaction. If you see a sudden jump, check whether it lines up with a FFIV price move, then confirm there is no new Form 4 transaction explaining the change.
Can I include Cajou Espoir in a verified net worth number, or is it always speculative?
The co-founder stake in Cajou Espoir is not something you can value confidently from SEC filings about FFIV. Unless there is a public disclosure of valuation or a partial sale that becomes reportable, private business ownership stays “unknown additive” in these estimates.
What is the best way to compare his net worth month to month without mixing methodologies?
If you want a consistent comparison over time, track the same valuation method: use the most recent Form 4 share count and multiply by a single price you define (for example, the closing price on the same day each month). Otherwise, changes may be methodology differences rather than real economic changes.
What events besides his trades should I watch for that could change the estimate?
Set alerts for new Form 4 filings under his CIK and also monitor FFIV for major corporate actions like splits, buybacks, or significant issuance. Corporate actions can alter share counts or prices and make estimates jump even when his ownership did not change directionally.
