Which Irwin Simon are we talking about?

The name Irwin Simon belongs to more than one public figure, so it is worth confirming upfront. The Irwin Simon most people searching for this topic have in mind is Irwin D. Simon, the Canadian-American businessman best known as the founder of Hain Celestial Group and, currently, as the Chairman, President, and CEO of Tilray Brands (TLRY), the cannabis and consumer goods company listed on NASDAQ. He built Hain Celestial from a small natural-foods startup in 1993 into a multi-billion-dollar company before departing in 2018, and he moved into Tilray's leadership role in 2019. That track record, combined with his current executive compensation package and insider share holdings, is the foundation of every credible net-worth estimate you will find.

The net worth estimate, as of April 2026

The honest answer is a range, not a single clean number. As of mid-to-late April 2026, credible insider-data platforms put Irwin D. Simon's net worth somewhere between roughly $6 million and $33 million, depending heavily on methodology. GuruFocus, which derives its estimate from disclosed insider transaction and ownership data, pegged the figure at 'at least $6 million' as of April 18, 2026. QuiverQuant, which cross-references SEC filings across multiple companies, came in considerably higher at 'at least $32.8 million' as of April 15, 2026. Benzinga recalculated its own estimate as of April 20, 2026, basing it on reported share holdings across multiple companies. All three platforms use the word 'at least,' which is a key signal: these are floors derived from publicly disclosed assets, not total wealth estimates that account for private holdings, cash, real estate, or other investments that don't show up in SEC filings.

Where these numbers actually come from

Every estimate in circulation traces back to the same category of primary source: SEC filings. The most important documents are Tilray's proxy statements and Form 4 insider transaction reports filed with the SEC for Irwin D. Simon. Tilray's 2024 proxy statement, filed with the SEC, discloses his total compensation for fiscal year 2024 as $10,142,971. That figure breaks down into a base salary, a cash bonus (target set at 200% of base salary, with $3,783,520 as the fiscal 2024 target but only $1,040,000 actually paid), and equity awards with a grant-date value of $4,547,501, calculated at $1.93 per share at the time of grant.

Form 4 filings on SEC EDGAR under the name 'SIMON IRWIN D' document every change in his beneficial ownership of Tilray shares. One transaction on record shows him purchasing 165,000 shares at an average price of $0.6067 per share, for a total investment of roughly $100,105. That kind of open-market purchase is the most transparent anchor available for estimating current share holdings, because it reflects real money committed at a known price. Simply Wall St cross-checks these holdings and expresses his stake as a percentage of total Tilray shares outstanding, which provides a useful sanity-check when the share price moves.

How the estimate is actually built (the methodology)

Minimal desk scene with documents, share-like tokens, and money ribbon implying equity-to-net-worth flow.

Net-worth estimates for corporate executives like Simon almost always follow the same basic formula: take the number of shares beneficially owned (from the most recent Form 4 or proxy), multiply by the current share price, then add any other publicly disclosed financial interests. That is what GuruFocus and QuiverQuant are doing. The large gap between their two estimates ($6 million vs. $33 million) likely reflects differences in which share classes or derivative securities they include, whether they count unvested RSUs and PSUs at full or partial value, and whether they net out any pledged or encumbered shares.

Tilray's compensation structure is heavily equity-weighted, which means the value is highly sensitive to the stock price. Restricted share units (RSUs) vest over time, and performance share units (PSUs) are tied to EBITDA targets and other conditions laid out in the 2024 proxy. The proxy explicitly states these awards are designed to link executives' interests to long-term financial performance. That is good for alignment with shareholders, but it also means Simon's net worth on paper can swing significantly with Tilray's share price, which has been volatile. Benzinga's approach of aggregating reported shares across multiple companies suggests they may also capture any residual holdings from his Hain Celestial tenure, which would push the number higher.

What is genuinely unknown without private disclosure: the value of any real estate Simon owns, cash and brokerage accounts, private equity or venture investments, deferred compensation balances, and wealth accumulated during his Hain Celestial years (which included substantial equity compensation over a 25-year run). None of that appears in current SEC filings, so all published estimates should be treated as lower-bound approximations of his total net worth.

Income vs. assets: what actually drives his wealth

For a career executive of Simon's tenure, wealth typically accumulates in two distinct phases. The first is earnings-driven: salary, bonuses, and equity vesting over decades at Hain Celestial (1993 to 2018) would have produced substantial cash flow. His compensation at Hain was in a comparable range to his current Tilray package for much of his later tenure there. The second phase is asset-driven: that accumulated equity and cash gets invested, and the returns on those investments begin to matter more than the annual paycheck.

At Tilray today, his 2024 compensation of just over $10 million is the visible income layer. But the bulk of his disclosed 'net worth' on platforms like GuruFocus and QuiverQuant is asset-driven, specifically the market value of his Tilray share holdings. If you are trying to estimate iris and carl apfel net worth instead, you would want to start from their own filings, assets, and any disclosed portfolio holdings rather than Tilray-specific equity values Tilray's share holdings. Because Tilray stock has traded at historically low price levels (the $0.60 range evident in his recent open-market purchase reflects a significant decline from earlier highs), the current market value of his equity stake is lower than it would have been even a few years ago. That is a critical context: the disclosed share count matters less than the current price applied to it.

Why different sites show different numbers

The $6 million to $33 million range is not a sign that one site is wrong. It reflects genuinely different methodological choices, all applied to the same underlying public data. Here are the main reasons estimates diverge:

Share scope: Some platforms count only directly owned shares. Others include shares held indirectly through family trusts, LLCs, or affiliated entities, plus derivative securities like options and unvested RSUs.
Vesting treatment: Unvested equity awards may be counted at full grant-date value, at a probability-weighted value, or excluded entirely until they vest.
Price snapshot timing: Because Tilray's stock price fluctuates, estimates calculated even days apart can differ by millions of dollars on the same share count.
Multi-company aggregation: Benzinga explicitly bases its estimate on shares across multiple companies. If Simon retains any legacy equity from Hain Celestial or other past directorships, including that data raises the total significantly.
Private assets: No platform has access to private wealth. All figures are floors, not totals.

The comparison table below shows how the three main platforms stack up on the key variables that explain the spread.

Platform	Estimate	As of Date	Basis
GuruFocus	At least $6 million	April 18, 2026	Insider transaction and ownership data (SEC filings)
QuiverQuant	At least $32.8 million	April 15, 2026	SEC filings, likely broader share/derivative scope
Benzinga	Recalculated estimate	April 20, 2026	Reported shares across multiple companies

How to check or update this number yourself today

If you want to verify or refresh the estimate rather than rely on a snapshot from a third-party site, the primary sources are all publicly accessible. Here is the practical sequence to follow:

Go to SEC EDGAR (sec.gov/cgi-bin/browse-edgar) and search for 'Simon Irwin D' as an insider. Pull the most recent Form 4 filings to see his current beneficial ownership of Tilray shares and any derivative securities. Note the total share count and the date of the last transaction.
Check Tilray's investor relations page (ir.tilray.com) for the most recent proxy statement. The Summary Compensation Table will show the latest fiscal year's total pay, and the beneficial ownership table will cross-confirm share counts.
Look up TLRY's current share price on any financial data site. Multiply Simon's confirmed share count by the current price to get a market-value floor for that portion of his wealth.
For a broader multi-company check, run his name through Benzinga's insider page or QuiverQuant's insider tracker to see if any holdings at other companies have been disclosed recently.
If you want to sanity-check against real-world context, search for recent interviews or press coverage. Executives sometimes reference compensation expectations or equity plans in earnings calls or conference presentations, which can provide forward-looking context on vesting schedules.
Adjust the estimate for known limitations: add a reasonable estimate for private wealth based on tenure (25 years of executive compensation at Hain alone suggests cumulative earnings well above what SEC filings show today), and note the date so the estimate remains properly contextualized.

What would move this number in the future

A few specific factors could change the estimate materially in either direction. The most significant upside driver would be a recovery in Tilray's share price. Given how equity-heavy his compensation structure is, even a doubling of TLRY's stock from current levels would meaningfully increase the market value of his holdings. Completion of PSU vesting cycles tied to EBITDA performance milestones would also add confirmed share grants to his ownership count. On the downside, any large share sales disclosed via Form 4 filings would reduce the equity-value floor, as would continued depression in the cannabis sector's public valuations.

It is also worth noting that Irwin Simon is one of several executive figures in the business and investment world who share similar names. If you have been researching other financial profiles in this space, the methodology described here, starting with SEC filings, cross-referencing proxy compensation tables, and treating all third-party estimates as floors rather than totals, applies consistently across any publicly traded company executive. The key habit is always checking the filing date and the share price date used in any calculation you are reviewing. If you are specifically looking for Irwin Tauber net worth, this same SEC-based share-and-compensation methodology is the starting point. If you are specifically looking for Irwin Chafetz net worth, you can use the same SEC-based share-and-compensation approach outlined here.

FAQ

Why do net-worth sites describe Irwin Simon net worth as an “at least” figure, even when they list a dollar amount?

Most public estimates treat only SEC-verifiable assets, primarily Tilray share holdings valued at a specific share price, as countable. They exclude private investments, real estate, non-public account balances, and some forms of deferred compensation, so the reported number functions as a floor rather than a full balance-sheet total.

Which SEC filing should I check first if I want to confirm Irwin Simon’s Tilray holdings?

Start with Tilray’s latest proxy statement for the clearest summary of compensation and equity awards, then use the most recent Form 4 filings for any updates to beneficial ownership. The proxy is best for award structure, while Form 4 is best for current share count changes from purchases or sales.

How can the share price date change the result, even if the reported share count is the same?

Because the methodology multiplies shares by a share price, using different price dates (for example, the day of an estimate versus a week later) can materially change the total. When comparing sites, confirm both the share count basis and the price timestamp they used.

Do unvested RSUs and PSUs automatically count as fully owned shares in Irwin Simon net worth estimates?

Not consistently. Some platforms value unvested awards at full grant value, some apply partial assumptions, and others only count vested holdings. If you see a large spread between estimates, a big part of it is often how each site treats RSUs and PSUs that are still subject to vesting conditions.

Why would one estimate be much higher if Irwin Simon is listed as owning multiple Tilray-related positions?

Beneficial ownership can include more than one category, such as direct shares, shares underlying options or derivatives, or shares held across entities. Different platforms may or may not include derivative exposures, pledged shares, or shares tied to specific award types, which can drive gaps even though all are referencing SEC data.

How do I tell whether a platform is including shares held through another company or residual holdings from an earlier tenure?

Check whether the estimate description explains multi-company aggregation beyond Tilray. If a site claims to factor in holdings from other periods or entities, look for whether it cites share counts from additional SEC filings. Without that transparency, it can be hard to verify what is included.

Can open-market transactions on Form 4, like a small purchase, be used to estimate current value reliably?

They help as an anchor for confirming share ownership changes, especially when they show price and quantity. But they are not enough alone, because subsequent sales, vesting, or award settlement could have occurred. Use the latest Form 4 beneficial ownership totals to confirm the most recent aggregate position.

What would count as a meaningful downside adjustment to Irwin Simon net worth estimates?

Large share sales disclosed on Form 4 are the cleanest downside signal, because they directly reduce the publicly reported ownership floor. Another downside factor is continued stock price weakness, since the market-value method makes equity-heavy estimates highly sensitive to valuation changes.

How do I handle the “different share classes” issue when interpreting Irwin Simon net worth comparisons?

If Tilray has multiple classes or if certain awards reference different instruments, the effective value can differ from the simplest “share count times price” approach. Compare whether each site applies the correct instrument valuation, not just the share count, when you see divergent totals.

Why might Irwin Simon net worth estimates not include his cash or real estate?

SEC filings for executives generally emphasize compensation and equity ownership, not full personal balance sheets. Cash, brokerage balances, and real estate typically do not appear unless specifically disclosed in limited contexts, so most net-worth tools omit them and instead estimate wealth primarily through equity holdings.

If I want a quick DIY range calculation, what minimal inputs do I need?

You need (1) the latest beneficial share count from the most recent relevant Form 4 or the proxy’s holdings section, (2) a current or chosen share price as of a specific date, and (3) a decision on whether to include any unvested awards (and how). Without agreeing on (3), you will usually reproduce the same kind of spread seen across websites.

What is the most common mistake people make when calculating Irwin Simon net worth from equity data?

Using share count figures that are outdated or mixing a proxy share count with a different date’s stock price without aligning timestamps. Another frequent error is treating all listed equity awards as already owned, instead of accounting for vesting and performance conditions.

Where do Irwin Simon net worth estimates go wrong when names are confusing or mixed?

There can be multiple people with similar names in business. Make sure you are using the SEC filings under the correct identity string (the specific “SIMON IRWIN D” record tied to the relevant company) and that the proxy and Form 4 data correspond to Tilray and the correct executive profile.
