[SCHEDULE 13G/A] Spartacus Acquisition Corp. II Amended Passive Investment Disclosure
Harraden discloses 3.16% stake in Spartacus Class A
Harraden Circle Investments, LLC and Frederick V. Fortmiller, Jr. report beneficial ownership of 726,100 Class A shares of Spartacus Acquisition Corp. II, representing 3.16% of the class.
Harraden Circle Investments, LLC and Frederick V. Fortmiller, Jr. report beneficial ownership of 726,100 Class A shares of Spartacus Acquisition Corp. II, representing 3.16% of the class. All voting and dispositive power over these shares is shared, with no sole power reported.
The shares are held for several Harraden-affiliated funds, with Harraden Circle Investments, LLC acting as investment manager and Mr. Fortmiller as its managing member. Following an internal reorganization effective June 30, 2026, certain prior reporting persons are no longer beneficial owners. This amendment is characterized as an exit filing, as the reporting persons have ceased to be beneficial owners of more than five percent of the outstanding Class A common stock. The Class A shares now carry CUSIP G8303R100, formerly G8303R126.

"have ceased to be the beneficial owners of more than five percent"
A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.
shared voting powerfinancial
"Shared Voting Power 726,100.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
dispositive powerfinancial
"Shared Dispositive Power 726,100.00"
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

Schedule 13Gregulatory
"This Amendment is being filed to report that the Reporting Persons"
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.
