TIG Arbitrage Associates in 2026: Why Its $145M SEC Form D, $1.8B AlTi Strategy AUM and $2.26B 13F Portfolio Tell Three Different Stories

TIG Arbitrage Associates in 2026: Why Its $145M SEC Form D, $1.8B AlTi Strategy AUM and $2.26B 13F Portfolio Tell Three Different Stories

INDEPENDENT VERDICT

TIG Arbitrage Associates L.P. is a particularly useful example of why a private-fund review cannot stop at a Form D headline. Its September 18, 2026 Form D/A reports $145,049,456 sold to 47 investors, yet parent-company disclosures describe the broader TIG Arbitrage strategy as managing approximately $1.8 billion at December 31, 2025, while TIG Advisors' June 30, 2026 Form 13F reports approximately $2.257 billion across 109 reportable holdings. Those numbers are not interchangeable and should not be presented as contradictions. The Form D belongs to one Delaware issuer; the $1.8 billion figure describes AlTi's broader event-driven strategy; and the 13F table reports specified long U.S. securities for TIG Advisors together with included TIG master funds rather than the net asset value of one feeder. The deeper story is also historical: AlTi states that the current TIG Arbitrage strategy dates to 1993, whereas this particular TIG Arbitrage Associates L.P. Form D identifies January 3, 2011 as its first sale. TIG then became part of publicly listed AlTi Global through the 2023 business combination involving Tiedemann, TIG and Alvarium. These layers make the fund highly verifiable, but they also make simplistic comparisons of "fund size" potentially misleading.

THREE REGULATORY NUMBERS — AND WHY THEY DO NOT MATCH

The latest reviewed Form D/A identifies TIG Arbitrage Associates L.P., CIK 0001507816, as a Delaware limited partnership and hedge fund using the same 22 Vanderbilt Avenue, 27th Floor, New York address now disclosed for TIG Advisors within AlTi Global. TFI Partners, LLC is identified as general partner and TIG Advisors, LLC as investment manager. The filing relies on Rule 506(b) and Section 3(c)(7), states an indefinite offering, records a January 3, 2011 first sale and reports $145,049,456 sold to 47 investors as of September 18, 2026. The more revealing comparison comes from a different SEC filing system. TIG Advisors' Form 13F for June 30, 2026 reports 109 entries with an aggregate value of $2,257,290,080 and specifically includes TIG Arbitrage Associates Master Fund, L.P. and TIG Arbitrage Enhanced Master Fund, L.P. as included managers. The Arbitrage Associates Master Fund separately filed a Form 13F notice stating that its holdings were being reported by TIG Advisors. This shows an identifiable master-level reporting architecture and helps explain why a feeder or investor-facing vehicle's Form D amount sold should not be expected to equal either 13F securities value or total strategy AUM.

FROM A 1993 ARBITRAGE STRATEGY TO A NASDAQ-LISTED PARENT

The ownership history is more important here than a generic manager biography. AlTi's SEC filings state that TIG was founded in 1980 as a platform supporting alternative investment managers and that the current version of the TIG Arbitrage strategy launched in 1993 with approximately $6 million. TIG later became part of the transaction combining Tiedemann Wealth Management Holdings, the TIG entities and Alvarium; the business combination closed on January 3, 2023, and the listed company subsequently adopted the AlTi Global name. AlTi now explicitly describes TIG Advisors as its subsidiary and its internally managed TIG Arbitrage product as an event-driven strategy. This means the current legal and website penetration does not lead to an independent boutique website alone: the relevant corporate parent is AlTi Global, a Nasdaq-listed financial-services organization. AlTi's legal disclosures identify TIG Advisors, LLC at 22 Vanderbilt Avenue, New York, with CRD 138306 and SEC File No. 801-65608, matching the regulatory identity appearing in TIG's own filings. The website-to-manager-to-parent-company chain is therefore directly confirmable rather than inferred from a similar brand name.

THE 0-TO-30-DAY MERGER WINDOW IS THE REAL STRATEGY DIFFERENTIATOR

TIG Arbitrage is not marketed as a broad equity hedge fund. AlTi describes the strategy as event-driven global merger arbitrage focused on events occurring during roughly the final 0-to-30-day portion of the merger process, with special emphasis on complex, hostile and "up-for-sale" situations where intensive primary research may create an informational advantage. That narrow catalyst window matters because the core risk is deal completion rather than ordinary long-term earnings growth. A regulatory intervention, financing failure, shareholder vote, competing bid, litigation event or deterioration in the target can rapidly change the merger spread. Historical scale also moved materially: AlTi reported approximately $3.0 billion for TIG Arbitrage at December 31, 2022, approximately $2.4 billion at December 31, 2023 and approximately $1.8 billion at December 31, 2025. Those changes deserve attention because they may reflect investor flows, investment performance, strategy capacity, market conditions or combinations of those factors; the public figures alone do not establish which driver dominated. In June 2025 AlTi also announced that TIG Arbitrage access was being expanded through the iCapital Marketplace for eligible wealth-management investors, adding a newer distribution channel to a strategy historically associated with institutional alternative investing.

WHAT THE PUBLIC 13F REVEALS — AND WHAT IT HIDES

TIG's 2026 Form 13F is valuable because it provides much more position-level visibility than investors usually get from a private hedge fund, but it should be interpreted carefully. The June filing reports roughly $2.26 billion of 13F securities and names two TIG master funds as included managers, yet a merger-arbitrage portfolio can contain important economic exposures that are not captured simply by reading the long-equity table. Deal hedges, shorts, derivatives, financing positions, foreign instruments, cash and other exposures can materially alter the net economics of an announced transaction. The 13F number can also exceed or differ from strategy AUM because gross reportable securities value is not the same concept as net investor capital. For TIG specifically, the correct diligence question is therefore not "Which of the three numbers is right" but "Which legal and accounting layer does each number measure" The 2026 filings provide unusually strong evidence that the answer involves feeder-level capital, master-fund holdings and strategy-level assets being reported under separate regulatory frameworks.

FINAL ASSESSMENT

TIG Arbitrage Associates has one of the deeper verifiable histories in this research batch: the strategy lineage reaches back to 1993 according to AlTi, the reviewed issuer has offered interests since 2011, TIG Advisors is an SEC-registered investment adviser, the manager became part of publicly traded AlTi through the 2023 business combination, the flagship strategy is described in AlTi's SEC reports, and the current portfolio has an additional transparency layer through Form 13F. The important unresolved questions are correspondingly more sophisticated than basic entity verification. An investor should determine where TIG Arbitrage Associates L.P. sits relative to TIG Arbitrage Associates Master Fund, how capital moves between feeder and master structures, how the Enhanced Master Fund differs from the primary master, how gross 13F exposure compares with net strategy exposure, and what drove the reduction in reported strategy AUM from approximately $3.0 billion in 2022 to $1.8 billion in 2025. Those questions are specific to TIG's structure and cannot be answered by the Form D alone. None of the SEC filings, adviser registration, AlTi ownership or Nasdaq listing represents SEC approval of the investment strategy.

THE THREE DIFFERENT SIZE METRICS

TIG Arbitrage Associates L.P. Form D Amount Sold Date: September 18, 2026 Amount: $145,049,456 Meaning: Securities sold by this specific exempt-offering issuer Not Equivalent To: Total TIG Arbitrage strategy AUM

TIG Arbitrage Strategy AUM Date: December 31, 2025 Amount Reported by AlTi: Approximately $1.8 billion Meaning: AlTi-reported assets of the broader TIG Arbitrage strategy Not Equivalent To: One feeder's Form D subscriptions

TIG Advisors Form 13F Value Report Date: June 30, 2026 Filing Date: August 14, 2026 Information Table Entries: 109 Reported Value: $2,257,290,080 Meaning: Reportable 13F securities held under TIG Advisors reporting structure Not Equivalent To: Net Fund NAV or total strategy AUM

Important Research Conclusion: The $145 million, $1.8 billion and $2.26 billion figures measure different regulatory layers and should not be presented as conflicting versions of the same number.

MASTER-FUND / REPORTING STRUCTURE

Structural Interpretation: Public filings establish a master-fund reporting relationship, but the exact subscription, ownership and economic relationship among every feeder and master vehicle should be confirmed from the current offering documents rather than inferred solely from Form 13F.

STRATEGY HISTORY AND AUM EVOLUTION

Current TIG Arbitrage Strategy Launch: 1993 Approximate AUM at Launch According to AlTi: $6 million

Reported Strategy AUM: June 30, 2022: Approximately $3.2 billion December 31, 2022: Approximately $3.0 billion March 31, 2023: Approximately $2.9 billion December 31, 2023: Approximately $2.4 billion December 31, 2025: Approximately $1.8 billion

Important Diligence Point: The public decline in reported AUM is observable, but available headline disclosures alone do not establish whether performance, redemptions, distributions, capacity management or other factors caused the change.

CORE INVESTOR QUESTIONS

  1. Does TIG Arbitrage Associates L.P. invest substantially all capital into TIG Arbitrage Associates Master Fund, L.P.
  2. What economic differences exist between the main Master Fund and TIG Arbitrage Enhanced Master Fund
  3. Which legal vehicle receives a new investor's subscription
  4. How should the $145.05 million Form D amount sold be reconciled with approximately $1.8 billion of strategy AUM
  5. Why does the June 2026 13F report approximately $2.26 billion of long reportable securities when AlTi reported $1.8 billion of strategy AUM at year-end 2025
  6. What percentage of the portfolio's economic exposure is invisible in Form 13F because of shorts, derivatives, foreign securities or other instruments
  7. What were the principal drivers of TIG Arbitrage AUM declining from approximately $3.0 billion in 2022 to approximately $1.8 billion in 2025
  8. What gross and net exposure limits apply during periods of unusually high merger activity
  9. How are failed-deal losses controlled when a spread widens abruptly
  10. How are hostile transactions and regulatory-sensitive mergers sized differently from lower-risk announced deals
  11. What management and incentive fee schedules apply to the specific investor vehicle
  12. Do iCapital-access investors receive exposure through the same legal vehicle and economics as institutional investors
  13. What redemption, lock-up, gate and suspension rights apply to TIG Arbitrage Associates
  14. How are opportunities allocated between the standard and enhanced master structures

ENTITY-SPECIFIC RISKS

Merger-spread risk can change abruptly if regulators challenge or delay a transaction. Hostile and contested transactions can remain unresolved longer than initially expected. A failed transaction can cause the target share price to fall significantly toward its unaffected value. Gross securities exposure visible on Form 13F can materially exceed net investor capital and should not be interpreted as NAV. The fund structure involves multiple reporting layers, making feeder-level Form D amounts unsuitable as a proxy for the entire strategy. The strategy's publicly reported AUM declined materially between 2022 and year-end 2025, and the cause should be investigated through current investor materials. Short and derivative exposures are not fully revealed by the public 13F long-holdings table. The 0-to-30-day event focus concentrates the investment process around transaction completion and catalyst timing. Standard and enhanced master-fund structures can carry different leverage or exposure characteristics that require document-level verification. Broader AlTi Global scale does not mean the parent company guarantees TIG fund obligations.

IMPORTANT FORM D NOTICE

Form D is a notice of an offering relying on an exemption from SEC registration and is not an SEC approval, endorsement, license or safety determination. Form 13F reports certain securities positions and should not be interpreted as a complete hedge-fund portfolio, net asset value or performance statement. Form ADV confirms an adviser's regulatory registration and disclosures but does not represent SEC approval of its investment strategy. FilingDossier independently compares issuer, adviser, holdings and parent-company records to distinguish these regulatory layers.

Important Form D notice: A Form D filing is a notice filing for an exempt securities offering. It does not mean that the U.S. Securities and Exchange Commission has approved, licensed, endorsed, or verified the issuer or the offering. Readers should verify information through official SEC sources and conduct their own due diligence.
