Insights

Corporate Governance Specialist

Harraden entities and managing member report shared 9.44% stake in Class A.

The filing identifies a group of affiliated private funds and their adviser structure that together hold 1,075,000 Class A shares. Shared voting and dispositive power is disclosed rather than sole control, consistent with pooled fund ownership.

Future disclosures will reflect any change in beneficial ownership or voting power. The relationships among GP, LP and adviser are standard for private investment funds and explain indirect beneficial ownership.

Securities Compliance Analyst

Schedule 13G used appropriately to report passive/beneficial ownership disclosure.

The schedule lists the reporting persons, address, CUSIP, amount beneficially owned, percent of class, and voting/dispositive power breakdowns as required. Signatures show the managing member authorized the filing.

Compliance implications are routine: any material change in ownership that affects the 5% threshold would require amendment per SEC rules.

4 terms

Schedule 13G regulatory

"This Statement relates to Shares (as defined herein) directly beneficially owned"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

beneficial ownership financial

"Amount beneficially owned: 1,075,000 (b) Percent of class: 9.44 %"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

shared dispositive power regulatory

"Shared Dispositive Power 1,075,000.00"

general partner corporate

"Harraden GP is the general partner to Harraden Fund"

A general partner is the person or firm that runs an investment partnership and legally represents it — they make the day-to-day decisions, choose which assets to buy or sell, and are responsible for the partnership’s obligations. Investors care because the general partner’s judgment, risk-taking and fee and profit-sharing arrangements determine both the potential returns and the level of exposure to losses; think of the GP as the ship’s captain whose skill and honesty shape the voyage’s outcome.
