Marc Swanson SeaWorld Net Worth: Estimate & Career Facts

Marc G. Swanson, the CEO of United Parks & Resorts Inc. (the company formerly known as SeaWorld Entertainment), has an estimated net worth in the range of $18 million to $28 million as of mid-2026. That range is built almost entirely on publicly disclosed figures: his SEC-reported beneficial ownership of 390,109 shares of company stock, his unvested equity awards (99,544 time-vesting RSUs and 80,500 performance PSUs), and a $450,000 annual base salary documented in the company's April 2026 proxy statement. There is no publicly available data on his real estate holdings, private investments, or other personal assets, so the estimate is equity-heavy and carries meaningful uncertainty on the upside.

Which Marc Swanson are we talking about?

If you searched 'Marc Swanson SeaWorld net worth,' you are almost certainly looking for Marc G.

There are other people named Marc Swanson in the world, but none with a documented public-company executive role at SeaWorld or its successor. For completeness, this site also covers Marc G. Swanson in a dedicated profile, which goes deeper on his biography. This article focuses specifically on the net worth calculation and its underlying data.

SeaWorld became United Parks, here's why that matters

In February 2024, SeaWorld Entertainment, Inc. rebranded to United Parks & Resorts Inc. and its stock ticker changed from SEAS to PRKS. The corporate entity is the same, the SEC filings are filed under the same company CIK, and Marc Swanson's tenure runs continuously across the name change. Any search for 'SeaWorld executive compensation' or 'SEAS proxy' will land on documents that now carry the United Parks & Resorts name, but the figures are directly comparable. Throughout this article, PRKS and United Parks are used interchangeably with the historical SeaWorld branding.

Marc Swanson's career timeline at SeaWorld and United Parks

Swanson has spent the bulk of his executive career inside the SeaWorld organization. He rose through senior finance roles, serving as Chief Financial Officer before stepping into the CEO role. His name appears in SEC filings dating back several years as a named executive officer, meaning his compensation has been publicly disclosed in the company's annual proxy statements for much of his tenure. As of the April 30, 2026 proxy filing, he is identified as the Chief Executive Officer of United Parks & Resorts Inc., the company's highest executive position. His longevity at one company is actually a useful data point for net worth estimation: it means his equity grants, vesting schedules, and salary history are contained within a single set of EDGAR filings rather than scattered across multiple employers.

Key milestones in his public record

• Long-tenured senior finance executive at SeaWorld Entertainment, including service as CFO
• Elevated to CEO role, confirmed in SEC filings and proxy disclosures
• Named in multiple Form 4 insider transaction filings on SEC EDGAR, including a May 15, 2023 option grant of 7,905 stock options at an exercise price of $56.92
• Listed as a named executive officer in the April 30, 2026 DEF 14A proxy statement filed with the SEC under the United Parks & Resorts Inc. name
• Beneficial ownership of 390,109 shares of PRKS common stock reported on Form 4 with a period-of-report date of December 31, 2025 (filing date January 5, 2026)

Documented compensation at SeaWorld and United Parks

The April 30, 2026 proxy statement (DEF 14A filed with the SEC) is the most detailed public source for Swanson's pay. Details on executive pay and equity awards are disclosed in the April 30, 2026 DEF 14A filing (United Parks & Resorts Inc. Definitive Proxy Statement (SEC)) United Parks & Resorts Inc. Definitive Proxy Statement (SEC) ; PRKS quote (MarketScreener). It discloses his 2025 base salary as $450,000. That is a relatively modest base for a theme-park CEO running a multi-property operation, but base salary is only one slice of the total compensation picture for executives at publicly traded companies. The proxy also reports the equity awards described below, and executives at this level typically receive annual performance bonuses tied to company metrics, though the exact bonus figure for any given year requires reviewing the full summary compensation table in the filing.

Equity awards: RSUs, PSUs, and stock options

The proxy discloses three categories of outstanding equity for Swanson. First, he holds 99,544 time-vesting restricted stock units (RSUs), which convert to shares of PRKS on a vesting schedule without requiring him to pay an exercise price. Second, he holds 80,500 performance-vesting PSUs, which are conditional on the company meeting specified performance targets before they convert to shares. Third, he has multiple outstanding non-qualified stock option tranches: 2,635 options with an exercise price of $56.92 (vesting May 11, 2026); 2,820 options at $53.18 with vesting dates in May 2026 and 2027; and 4,368 options at $34.33 with vesting beginning November 11, 2026 and continuing in 2027 and 2028. The total option count across these tranches is 9,823, which is relatively small compared to the RSU and PSU balances.

Other income sources and assets, what is and isn't public

Beyond his PRKS compensation, there is no publicly available documentation of Swanson's personal real estate, private investments, business interests, or other financial holdings. He is not a founder of a separate venture, does not appear prominently in real estate transaction databases as a public record, and has not been reported in financial press as having major outside investments. That does not mean those assets don't exist, only that they are not in the public domain. For a long-tenured public-company executive earning compensation in the range documented above, it is reasonable to assume some level of diversified personal savings, retirement accounts, and possibly real estate, but none of that can be quantified without private information. The net worth estimate in this article is therefore anchored almost entirely to the PRKS equity position, which is the only asset class with hard public data.

The net worth estimate: numbers, math, and the range

Here is how the estimate is constructed, transparently, using only figures from SEC filings and market data sources. The starting point is the beneficial ownership of 390,109 shares reported on the Form 4 filed January 5, 2026 (period of report December 31, 2025). Two price points are used to bracket a range. The December 31, 2025 adjusted closing price for PRKS was $36.30 (per financial data aggregators covering that date). The more recent price as of August 7, 2026, reported by MarketScreener, is $47.36.

Adding the unvested equity at the current price gives a gross paper value, not a net worth figure, but it shows the upper bound of equity-linked wealth. At $47.36, the 99,544 RSUs and 80,500 PSUs (combined 180,044 units) are worth approximately 180,044 × $47.36 = $8,526,884 on paper. Stacking that on top of the share value at the same price: $18,475,562 + $8,526,884 = $27,002,446. That is the gross, pre-tax, pre-forfeiture equity figure.

The stock options are a much smaller contributor. Tranches 1 and 2 (exercise prices of $56.92 and $53.18) are currently out of the money relative to the $47.36 market price, meaning they have no intrinsic value right now. Tranche 3 (4,368 options at $34.33) is in the money, with an intrinsic value of approximately ($47.36 - $34.33) × 4,368 = $56,899 before tax and before considering they are not yet fully vested. That is a rounding error relative to the equity position, but it is included for completeness.

A realistic net worth estimate applies meaningful discounts to these gross figures. PSUs may not vest if performance targets are missed. RSUs have not vested and shares withheld for tax payments at vesting reduce the realized value (Form 4 filings note shares withheld for tax purposes). Federal and state income taxes on vesting equity can exceed 40% of the gross value in high-tax states. Applying a rough 40% haircut to unvested equity and acknowledging that realizable value of vested shares is closer to the lower-price scenario, a conservative net worth figure for equity alone lands around $16 to $19 million. The higher end of the range, including a portion of unvested equity and the current higher share price, reaches approximately $25 to $28 million. Adding a conservative assumption for personal savings, retirement accounts, and possible real estate, the overall estimated net worth range is $18 million to $28 million, with the midpoint around $22 to $23 million.

How each number was sourced

Every figure in this estimate comes from a specific document type. Supporting documents include the Form 4 filing for Marc G. Swanson (see Form 4 - Swanson Marc (SEC) ; PRKS quote (MarketScreener)). The beneficial share ownership (390,109 shares) comes from a Form 4 filed January 5, 2026, with a period-of-report date of December 31, 2025 (SEC EDGAR, accession number 0001193125-26-003076). The RSU and PSU counts (99,544 and 80,500 respectively) come from the outstanding equity award tables in the April 30, 2026 DEF 14A proxy statement. The stock option details, including exercise prices and vesting dates, also come from that same proxy. The $450,000 base salary is from the executive compensation table in the same DEF 14A. The December 31, 2025 PRKS price of $36.30 comes from financial data aggregators covering PRKS price history. The August 7, 2026 price of $47.36 is the MarketScreener reported quote for PRKS on that date. SEC proxy statements (DEF 14A) are public documents filed annually by companies on behalf of their shareholders; they are the gold standard for executive compensation disclosure and are freely accessible on SEC EDGAR. Form 4 filings are insider transaction reports that executives must file within two business days of a transaction, making them reliable and timely.

Uncertainties, assumptions, and what this estimate can't tell you

Several important caveats apply to any estimate built on public equity data. First, the share price fluctuates daily, so the equity value of Swanson's PRKS holdings changes with every trading session. A 10% move in the stock price shifts the vested share value alone by roughly $1.8 million. Second, PSUs are contingent on performance: if United Parks misses its performance targets in the relevant measurement period, some or all of those 80,500 PSUs could be forfeited entirely. Third, shares reported as beneficially owned in a Form 4 may include shares that are pledged, subject to lock-up agreements, or otherwise restricted in ways not visible from the filing alone. Fourth, there is no way to know from public records whether Swanson has sold any shares through a 10b5-1 plan or other mechanism since the December 31, 2025 Form 4 period date; additional Form 4 filings since that date would need to be checked for updates. Fifth, taxes are a major real-world reducer of equity-linked wealth: the gross figures cited above are pre-tax, and marginal federal rates plus any state income tax can take 37 to 50 cents of every dollar when equity vests. Sixth, no information is available about mortgages, debt, or other liabilities, which would reduce true net worth below the asset figures estimated here.

How Swanson compares with peer SeaWorld executives

Theme park and entertainment resort CEOs at mid-cap public companies typically see total compensation packages in the $3 million to $8 million range annually when salary, bonus, and equity grants are combined, though this varies widely based on company size and recent performance. United Parks & Resorts operates roughly a dozen parks and competes in a sector that includes Cedar Fair (now merged with Six Flags), Herschend Family Entertainment, and others. Swanson's $450,000 base salary is on the conservative end for a public-company CEO of comparable scale, suggesting his total compensation is heavily weighted toward at-risk pay (bonuses and equity). The 390,109-share beneficial ownership stake, valued at roughly $14 to $18 million at recent prices, is a meaningful but not outsized holding relative to peer-company CEOs at similarly sized operators. Proxy benchmarking data filed by the company would show the compensation committee's peer group comparisons, which typically span leisure, hospitality, and entertainment companies with similar revenue profiles.

Reader questions and update note

Is Marc Swanson a billionaire? No. His documented equity and compensation place him firmly in the range of a successful public-company executive, not the ultra-high-net-worth category. Does his net worth change when SeaWorld (now United Parks) stock moves? Yes, significantly. Each $1 change in the PRKS share price moves the paper value of his 390,109 vested shares by about $390,000. That means a meaningful stock swing can shift the estimate by millions of dollars in either direction. What would push the estimate higher? Full vesting of the 80,500 PSUs at a higher stock price, plus any additional equity grants disclosed in future proxy filings, would be the biggest upside drivers. What would push it lower? Stock price declines, PSU forfeitures due to missed performance targets, or large tax withholdings at vesting would all reduce realized wealth.

This estimate was last updated using data current as of August 7, 2026. The primary triggers for a revision are: the filing of a new DEF 14A proxy statement (typically in April or May each year), any Form 4 insider transactions filed by Swanson on SEC EDGAR showing material changes to his share ownership, significant moves in the PRKS share price, or news reports documenting compensation changes or personal financial transactions.
