Investment Management Agreementregulatory
"Armistice Capital is the investment manager of Armistice Capital Master Fund Ltd."
An investment management agreement is a written contract that hires a professional to make buying, selling and strategy decisions for an investment account or fund, and sets out their duties, fees, risk limits, performance measures and reporting requirements. It matters to investors because the agreement determines who controls the money, how much the service costs, what risks are allowed, and how success or failure is measured—think of it as the service contract that defines expectations and remedies for a hired portfolio manager.
beneficially ownfinancial
"Armistice Capital exercises voting and investment power ... and thus may be deemed to beneficially own"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
shared voting powerfinancial
"Shared Voting Power 9,299,917.00"
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.
Armistice reports beneficial ownership of 9,299,917 shares, equal to 9.99% of Citius Oncology's common stock as of 03/31/2026. The shares are held directly by the Master Fund.
Who holds voting and investment power over these CTOR shares?
The filing states Armistice Capital exercises shared voting and dispositive power over the 9,299,917 shares pursuant to its Investment Management Agreement with the Master Fund.
Does Steven Boyd personally own the reported CTOR shares?
Steven Boyd is reported as managing member of Armistice Capital and may be deemed to beneficially own the shares through that role; the filing lists shared voting and dispositive power attributed to him via Armistice.
What does the Master Fund's disclaimer mean in this filing?
The Master Fund disclaims beneficial ownership because, per the filing, it lacks the ability to vote or dispose of the securities due to the Investment Management Agreement with Armistice Capital.
When was this Schedule 13G/A signed?
