INDEPENDENT VERDICT
Hidden Lake Asset Management has a regulatory footprint that is unusually useful for cross-checking because the manager appears simultaneously in SEC investment-adviser records, recurring Form D filings and quarterly Form 13F reports. The September 18, 2026 filings show Hidden Lake Onshore Fund LP with $22,921,993 sold to 18 investors and Hidden Lake Offshore Fund Ltd. with $2,402,491 sold to six investors, while the manager's March 2026 Form ADV reported approximately $378.26 million in regulatory assets under management. Hidden Lake Asset Management LP is separately SEC registered under CRD 298209 and SEC File No. 801-115096, with registration effective since May 2019. The most distinctive feature is that the public record exposes several different layers of the same hedge-fund business: a Delaware onshore vehicle, a Cayman offshore vehicle, a separate Japan-focused offshore fund, SPVs and a publicly reported U.S. equity book through Form 13F. Investors therefore should not use one filing in isolation or assume that the $22.9 million Form D figure represents the firm's total assets.
ONSHORE AND OFFSHORE FUNDS: SAME MANAGER, DIFFERENT LEGAL VEHICLES
Hidden Lake Onshore Fund LP, CIK 0001750426, is a Delaware limited partnership whose Form D history extends back to 2020. Its September 18, 2026 amendment reports an indefinite offering, $22,921,993 sold and 18 investors, with Hidden Lake Asset Management LP identified as investment manager and Hidden Lake Fund GP LLC identified as general partner. Kevin Mok signed the filing as managing member of the general partner. Hidden Lake Offshore Fund Ltd., CIK 0001750427, is a Cayman Islands exempted company managed by the same adviser. Its September 18, 2026 amendment reports $2,402,491 sold to six investors and identifies John Morelli, Brad Cowdroy and Julie O'Hara as directors, with Morelli signing the filing. The offshore vehicle also states that the investment manager receives customary management fees. These are related structures but legally separate issuers, so investors should determine whether both feed into one master portfolio, maintain identical exposure or serve different investor tax and regulatory needs.
THE UNIQUE STORY: FORM D CAPITAL IS ONLY ONE SLICE OF THE ACTUAL PLATFORM
Hidden Lake is a strong example of why Form D amount sold should never be treated as equivalent to total manager AUM. The manager's March 27, 2026 Form ADV reports approximately $378.26 million of regulatory assets under management, all discretionary, across five client accounts, with private-fund gross assets reported at approximately the same level. That is far above the $22.92 million reported by the onshore fund and the $2.40 million reported by the offshore vehicle in their September Form D amendments. The difference is not inherently contradictory: adviser AUM can include assets held across multiple funds and structures, while Form D reports securities sold by a specific issuer. Hidden Lake's SEC filings also identify additional vehicles, including Hidden Lake Japan Offshore Fund Ltd. and Hidden Lake SPV I LLC. For FilingDossier purposes, this makes Hidden Lake a particularly clear case of why manager-level AUM, issuer-level capital sold and publicly reported securities holdings must remain separated.
13F PORTFOLIO TRANSPARENCY AND WHAT IT DOES NOT SHOW
Unlike many private hedge funds whose positions remain almost entirely opaque, Hidden Lake Asset Management also files Form 13F as an institutional investment manager. Its August 14, 2026 report for the quarter ended June 30 listed 24 reportable positions with an aggregate reported 13F value of approximately $332.21 million. This provides a rare public window into a substantial portion of the manager's U.S.-listed long equity exposure and creates a second regulatory dataset that can be compared with the manager's ADV and private-fund filings. However, investors should not interpret the 13F total as the fund's net asset value or full portfolio. Form 13F generally captures specified long U.S.-listed securities and does not provide a complete picture of short positions, derivatives, many foreign securities, cash, financing arrangements or other exposures. For a hedge fund, those omitted positions can materially change the economic risk of the portfolio.
JAPAN FUND AND MULTI-VEHICLE ARCHITECTURE
Hidden Lake's structure extends beyond a conventional U.S./Cayman pair. Hidden Lake Japan Offshore Fund Ltd., CIK 0001999340, was organized in the Cayman Islands in 2023 and separately identifies Hidden Lake Fund GP LLC as general partner and Hidden Lake Asset Management LP as investment manager. The latest adviser records also identify the Japan vehicle as part of Hidden Lake's private-fund structure. This suggests that the manager has developed distinct investor or strategy sleeves rather than operating only one universal hedge fund. Hidden Lake SPV I LLC adds another example of vehicle-level segmentation. The core diligence question is therefore allocation: investors should determine how trade ideas, position sizes, capacity-constrained investments and expenses are divided among the flagship onshore and offshore funds, Japan vehicles, SPVs and any additional accounts. The existence of multiple legal vehicles can be operationally normal, but it makes conflicts and allocation policies particularly important.
FINAL ASSESSMENT
Hidden Lake Asset Management has a strong public regulatory identity despite maintaining a relatively limited public marketing footprint. SEC adviser registration, recurring Form D amendments, a current Form ADV, a Form 13F reporting history and multiple consistently named fund entities all independently support the existence of the manager and its investment platform. The most important diligence issue is not whether Hidden Lake exists, but how the individual vehicles fit together and what risks are not visible in the public equity filings. Investors should obtain the current offering memorandum and audited financial statements, identify the full long and short portfolio construction process, understand leverage and derivatives usage, review liquidity and redemption terms, and verify allocation policies among onshore, offshore, Japan and SPV structures. The September 2026 Form D figures provide issuer-level fundraising evidence, while the approximately $378 million adviser AUM and $332 million June 2026 13F portfolio provide separate manager-level context. None of those figures represents SEC approval, verified investment performance or a guarantee that investors can redeem at reported asset values during stressed markets.

CORE INVESTOR QUESTIONS
- Do the onshore and offshore funds feed into the same master portfolio
- Why is the Form D capital sold much smaller than the manager's approximately $378 million regulatory AUM
- What assets or accounts explain the difference between issuer-level Form D amounts and adviser-level AUM
- How does Hidden Lake Japan Offshore Fund differ from the flagship strategy
- How are investment opportunities allocated among the onshore fund, offshore fund, Japan vehicle and SPVs
- What long / short gross and net exposure limits apply
- How much leverage and derivative exposure can the funds use
- What percentage of actual risk is visible in the public Form 13F portfolio
- What management fee and incentive allocation apply to each vehicle
- What redemption notice, lock-up, gate and suspension provisions apply
- How are hard-to-value securities priced
- Which administrator, auditor, prime broker and custodian currently service the funds
CORE RISKS
Form 13F shows only part of a hedge fund's true economic exposure. Short positions and derivatives can materially change portfolio risk. Leverage can magnify both gains and losses. Multiple fund vehicles create allocation and conflict-management questions. The Japan fund may carry region-specific market and currency risks. Onshore and offshore investors can face different tax and legal treatment. Reported adviser AUM should not be confused with capital raised by one Form D issuer. Private-fund interests can have meaningful redemption restrictions. Illiquid or complex positions can be difficult to value during market stress. Performance-based compensation can create incentive-related conflicts. SEC adviser registration does not constitute SEC approval. Form D and Form 13F filings do not verify future investment performance.

IMPORTANT FORM D NOTICE
Form D is a notice filing for an offering relying on an exemption from SEC securities registration. The SEC states that information in Form D has not necessarily been reviewed by the Commission and should not be assumed to be accurate or complete. Form ADV registration and Form 13F reporting likewise do not constitute SEC approval or endorsement of Hidden Lake Asset Management, its funds or investment performance. FilingDossier independently compares issuer-level filings, adviser-level disclosures and institutional holdings reports for research purposes. Investors should obtain and review the current offering memorandum, partnership or corporate documents, audited financial statements, fee schedule, allocation policy, valuation policy and official regulatory records before making an investment decision.
