Andrew Bursky's net worth is not a number you'll find neatly published anywhere, and that's not an accident. The most visible estimate floating around online, roughly $352 thousand from Benzinga, is almost certainly a dramatic undercount. It only captures the publicly disclosed stock holdings of a man whose real wealth is almost entirely tied up in private equity and control stakes through Atlas Holdings, the Greenwich-based industrial investment firm he co-founded in 2002. A more defensible range for Andrew M. Bursky's net worth, accounting for his career trajectory, private firm equity, and philanthropy signals, sits somewhere between $100 million and $500 million or more, though pinning a precise figure is genuinely impossible from public records alone.
Andrew Bursky Net Worth: Estimate, Breakdown, and How to Verify
Who is Andrew Bursky?
The Andrew Bursky most people are searching for is Andrew M. Bursky, a private equity and industrial investment executive based in Greenwich, Connecticut. He graduated from Washington University in St. Louis in 1978 with three degrees: a bachelor's in economics, a bachelor's in chemical engineering, and a master's in chemical engineering. He then completed an MBA at Harvard Business School in 1980. That combination of engineering and finance training set the template for a career spent buying and rebuilding industrial businesses.
After Harvard, Bursky co-founded Interlaken Capital in 1980 and served as managing director there until 1999. He then co-managed Pegasus Capital Advisors from June 1999 to April 2002, before co-founding Atlas Holdings in 2002 alongside Timothy J. Fazio. Atlas began with the purchase of a small paper mill in rural Indiana and has since grown into a significant industrial holding company focused on control investments and operational turnarounds. Bursky also sits on the board of Greenidge Generation Holdings, a company Atlas affiliates acquired in February 2014, and he serves as a Trustee at Washington University, where the Bursky Center for Human Immunology and Immunotherapy bears his and his wife Jane's names. That philanthropic footprint is one of the clearest public signals that this is a person of significant, not modest, wealth.
It's worth noting that the name 'Andrew Bursky' can create confusion with other individuals who share similar names. This profile refers specifically to Andrew M. Bursky, the Atlas Holdings co-founder with the WashU and Harvard pedigree, SEC insider filing history under CIK 0000905112, and board role at Greenidge Generation Holdings. If you're cross-referencing with related profiles, Alan Bursky is a separate individual with his own distinct financial profile.
How net worth estimates are built for someone like Bursky
For public figures tied primarily to private businesses, net worth estimates are assembled from a patchwork of public signals rather than any single definitive source. The main inputs are SEC filings (Forms 3 and 4, Schedules 13D and 13G, S-1 registration statements, and DEF 14A proxy filings), company founding and ownership history, philanthropic commitments and named gifts, and any public-record property data. Each of these is a partial window, not a complete picture.
Aggregator sites like Benzinga use a narrower methodology: they pull insider-trade filings and assign a market value to the reported shares. Benzinga's estimate for Bursky ($352 thousand, last recalculated November 1, 2024) is derived entirely from his publicly disclosed share positions in companies like Sylvamo Corp, Greenidge Generation Holdings, Horizon Global Corp, and Strategic Distribution Inc. That's a legitimate approach for someone whose wealth is mostly in publicly traded stocks. For Bursky, whose core asset is a private equity partnership interest in Atlas Holdings, it captures almost nothing meaningful.
The estimated net worth range, and what drives it
Based on available public information as of April 2026, a defensible estimated net worth range for Andrew M. Bursky is $100 million to $500 million, with the true figure possibly higher depending on Atlas Holdings' current portfolio value and Bursky's specific equity split with co-founder Fazio. That range is wide for a reason: the dominant asset here is a private equity stake, and private equity stakes are not marked to market publicly.
The lower bound reflects a conservative reading of what a career spanning over four decades in industrial private equity, starting with Interlaken Capital in 1980 and running through Atlas Holdings' portfolio growth since 2002, would plausibly produce even without blockbuster exits. The upper bound reflects the scale of philanthropy (naming a center at Washington University is a multi-million-dollar commitment), the longevity and apparent success of Atlas Holdings as an industrial turnaround platform, and the management fees and carried interest that typically accrue to co-managing partners of private equity firms over decades. The Benzinga figure of $352 thousand should be treated as a floor for publicly observable stock holdings only, not a net worth estimate in any complete sense.
Breaking down how the money is made
Interlaken Capital (1980 to 1999)
Bursky co-founded Interlaken Capital in 1980 and ran it as managing director for nearly two decades. This was the foundational wealth-building period. Private equity managing directors at successful firms typically earn a combination of management fees, carried interest (a share of investment profits, usually 20%), and co-investment returns. Nineteen years in that role across the deal-heavy 1980s and 1990s would have generated substantial capital accumulation, even if exact figures are not publicly available.
Pegasus Capital Advisors (1999 to 2002)
The three-year stint co-managing Pegasus Capital Advisors was a bridge between Interlaken and Atlas. Pegasus is a real assets and sustainability-focused private equity firm. The role as co-managing partner would have continued the carried interest and fee income pattern, and likely expanded Bursky's deal network ahead of Atlas's founding.
Atlas Holdings (2002 to present)
This is the primary wealth engine. Atlas Holdings is an industrial private equity and operating company that started with a single paper mill and has grown to hold multiple platform companies across manufacturing, distribution, and energy. As co-managing partner, Bursky holds an equity and economic interest in the general partner entities that control Atlas's funds and portfolio companies. SEC proxy filings related to Greenidge Generation Holdings show that Bursky and Fazio are each managers and managing partners of certain GP entities and may be deemed to control entities holding significant securities positions. A DEF 14A filing disclosed Bursky as a beneficial owner of 6,312,454 shares in Greenidge-related entities, reflecting both direct and indirect control. That's just one portfolio company; Atlas's full portfolio compounds the picture considerably.
Board and advisory roles
Bursky's board seat at Greenidge Generation Holdings, the Atlas-acquired power and Bitcoin mining company, and his trustee and governance roles at Washington University add modest cash compensation and equity exposure in some cases, but are secondary to his Atlas partnership economics.
Assets and investments worth considering
The dominant asset class for Bursky is almost certainly private equity, specifically his partnership interest in Atlas Holdings and its affiliated GP entities. Beyond that, the following asset categories are plausible based on publicly available signals.
- Atlas Holdings equity and carried interest: The most significant wealth driver. As co-managing partner since 2002, Bursky's interest in Atlas's GP entities would include both a share of management fees and a portion of carried interest from portfolio company exits over more than two decades.
- Greenidge Generation Holdings stock: The DEF 14A filing shows beneficial ownership of over 6.3 million shares through related entities. The value of this stake fluctuates with Greenidge's stock price, which has been volatile given its Bitcoin mining exposure.
- Publicly traded minority positions: Insider filings track positions in Sylvamo Corp, Horizon Global Corp, and Strategic Distribution Inc., though these appear to be modest relative to private holdings.
- Real estate: Greenwich, Connecticut is one of the most expensive residential markets in the United States. Senior private equity executives in that market routinely hold primary residences and potentially additional properties worth multiple millions of dollars, though no specific property records have been publicly surfaced in available research.
- Philanthropic endowments: The Bursky Center naming gift at Washington University represents a committed philanthropic capital outflow, which signals existing liquid or near-liquid wealth well above the donation amount itself.
Why the numbers vary so much, and what to watch out for
The gap between Benzinga's $352 thousand figure and a realistic multi-hundred-million-dollar range comes down to one core problem: most net worth aggregators are built to handle public company executives whose wealth is primarily in publicly traded shares. If you are specifically looking for Andrew Gamberzky net worth, separate that question from the public-company share figures discussed here. They ingest SEC Form 3 and Form 4 data, multiply share counts by current prices, and report the result. For someone like Bursky, whose equity is mainly in a private partnership, that method captures only the tip of the iceberg.
There are also structural layers that make indirect ownership easy to miss. Bursky's control over Greenidge securities, for instance, runs through GP entities where he and Fazio are co-managers. An aggregator that maps only direct personal holdings will miss economically significant control positions held through those structures. The Benzinga recalculation date of November 1, 2024, also means the figure hasn't been refreshed with any Form 3/4 activity that may have occurred in the months leading up to April 2026.
A few red flags to watch for when reading Bursky net worth claims online: any figure below $10 million should be treated skeptically given career tenure and philanthropy signals; any figure presented without explaining whether private equity stakes are included is incomplete by definition; and name confusion with other individuals named Andrew Bursky or similar names is a real risk with lesser-known financial figures. Always verify the person by cross-checking education (WashU 1978, Harvard MBA 1980), employer (Atlas Holdings, Greenwich CT), and SEC CIK number (0000905112).
| Source Type | What It Captures | What It Misses | Reliability for Bursky |
|---|---|---|---|
| Benzinga insider-trade aggregator | Publicly reported share positions in listed companies | Private equity stakes, real estate, other private assets | Low (underestimates significantly) |
| SEC Form 3/4 filings | Direct and disclosed indirect share ownership | Unvested interests, private firm equity, carried interest | Moderate (useful for public holdings only) |
| DEF 14A / Schedule 13D filings | Beneficial ownership including control entities | Personal net worth beyond disclosed securities | Moderate-high (best public signal for equity control) |
| Philanthropy / named gifts | Signals minimum wealth threshold for major commitments | Exact dollar amounts, liquidity profile | Useful as a floor signal only |
| Private equity GP documents | Partnership economics, carried interest, fee structures | Almost entirely non-public | Not accessible publicly |
How to check for the latest updates today
If you want the most current picture of Andrew M. Bursky's publicly observable financial footprint as of April 2026 or later, here's the practical checklist to work through.
- Search SEC EDGAR for CIK 0000905112 (Andrew M. Bursky) to pull the latest Form 3 and Form 4 insider transaction filings. These will show the most recent publicly reported changes to his stock holdings across all tracked companies.
- Search EDGAR for Atlas Holdings LLC and related entities to find any new S-1, S-1/A, or Schedule 13D/13G filings that reference Bursky as a controlling person or beneficial owner.
- Check the Greenidge Generation Holdings investor relations page for the most recent DEF 14A proxy filing. The proxy will include updated beneficial ownership tables showing Bursky's current share count and any changes in controlling-entity structures.
- Compare the current Benzinga recalculation date against the latest Form 3/4 timestamps to see whether the aggregator has refreshed since new filings were made. If the recalculation date is stale, the Benzinga number is stale.
- Look up Atlas Holdings' current company website and any recent press releases for portfolio additions or exits. Each exit from a platform company can trigger carried interest realizations that materially affect the co-managing partners' wealth.
- Search Washington University news and philanthropy announcements for any updated giving or naming gifts, which can provide indirect signals of liquidity events.
- Run a federal court docket search (PACER or Justia) for Andrew M. Bursky and Atlas Holdings LLC to check for any active litigation that could affect asset values or ownership structures.
The honest bottom line is that a precise net worth figure for Andrew M. Alan Bursky net worth questions should be handled separately as well, since this article is about Andrew M. Bursky's financial profile. Bursky is not publicly knowable with confidence, and anyone claiming otherwise is either guessing or working from the same incomplete public data this profile is built on. What is defensible is that this is a person whose wealth, built over more than 40 years in private equity, is almost certainly in the nine-figure range and could well exceed that depending on Atlas Holdings' portfolio performance. Eric Bugenhagen net worth is the kind of figure that varies widely across sites, so it is worth checking the underlying holdings and methodology. The $352 thousand figure circulating on aggregator sites is a measure of his publicly disclosed stock positions, not his net worth, and those are very different things. Many readers are also searching for Bugsy Siegel net worth, but that is a separate historical figure from Andrew Bursky. Many readers are also searching for fred bugsy buggs net worth as a related comparison, but that is a separate historical figure from Andrew Bursky. If you are specifically researching indybugg1 net worth, it is best to rely on verified sources and avoid mixing unrelated biographies.
FAQ
How can I tell whether an online “Andrew Bursky net worth” number includes private equity interests or only public stock holdings?
Check whether the claim explains methodology. If it only references SEC insider transactions and multiplies share counts by market prices, it is almost certainly limited to publicly disclosed stock positions and will miss partnership/control interests held through Atlas and related GP entities.
What SEC filings matter most for verifying Andrew M. Bursky’s ownership when he has control positions through other entities?
Look beyond direct Form 3 and 4 trades, and focus on Schedule 13D or 13G filings plus proxy materials (DEF 14A). Those documents often describe indirect control or beneficial ownership through manager or GP structures, which is where “direct-only” aggregators undercount.
Why might Benzinga’s figure look extremely small compared with the plausible nine-figure range?
Because it is effectively a snapshot of publicly observable shares valued at current prices. If the majority of wealth is tied to partnership economics in private equity, the public-share valuation captures only a minor portion, even if the person controls significant securities via affiliated entities.
Is there a single public document that can confirm Andrew Bursky’s exact net worth?
Usually no. Private equity partnership stakes are not marked to market in public disclosures the way traded stock is, and beneficial ownership disclosures typically show holdings and control, not a full, updated balance-sheet style net worth figure.
How should I interpret “beneficial ownership” numbers versus personal ownership?
Beneficial ownership can include shares held through entity ownership, trustee roles, or management/control arrangements. For someone in private equity with GP entities, beneficial ownership figures can reflect economic influence without representing the entire value of a partnership interest.
What are common name-mixups that lead to incorrect net worth conclusions for “Andrew Bursky net worth”?
The biggest mistake is assuming every “Andrew Bursky” result refers to Andrew M. Bursky of Atlas Holdings. Use identity checks like education history, employer (Atlas Holdings in Greenwich), and the SEC CIK (0000905112) before trusting any net worth figure.
If someone claims Andrew Bursky is worth less than $10 million, what should I look for to validate or dismiss it?
Treat it as a red flag unless they clearly include private equity partnership interest value and address why long-tenure partner compensation would not translate into major equity stake accumulation. Without that explanation, the number is likely derived from direct, publicly traded holdings only.
How can I update the publicly observable portion of Andrew Bursky’s wealth beyond the aggregator’s last recalculation date?
Re-check recent Form 3 and Form 4 filings for CIK 0000905112 and review any new DEF 14A or Schedule 13D/13G updates. Aggregator snapshots can lag, so the best “current” public view comes from filing-level updates.
Does board or trustee compensation meaningfully affect net worth compared with private equity partnership interests?
Usually it is secondary. Director and trustee roles may add cash and small equity exposure, but for someone whose dominant asset is a partnership interest in Atlas and affiliated GP entities, the partnership economics typically drive most of the net worth range.
What’s the most reliable way to phrase my conclusion if I need a defensible estimate rather than an exact number?
Use a range and define what is included. A defensible approach is to state that public share valuations represent only a portion, then cite a broader range that accounts for private equity partnership/control interests, explaining that precision is not verifiable from public records alone.
