Insights

Armistice reports a significant passive stake under a 13G framework.

Armistice Capital and Steven Boyd report beneficial ownership of 9.46% via 6,012,000 shares as of 03/31/2026. The filing is a routine disclosure under Section 13 tracking large passive positions and clarifies voting and dispositive powers.

The filing states the Master Fund is the direct holder and that an Investment Management Agreement gives Armistice voting and investment authority; the Master Fund nonetheless disclaims direct beneficial ownership in the text. Subsequent filings would show any change in intent or classification.

Position size is notable but presented as managed on behalf of a fund.

The reported 6,012,000-share stake equals 9.46% of the class per the filing, a scale that can be meaningful for activist potential or block trading liquidity considerations. The filing does not state any plans to change holdings.

Cashflow/transaction intent is not stated; the document attributes decision authority to Armistice Capital under its management agreement, while the Master Fund retains economic interest. Investors should watch future amendments for any change in percentage or filing classification.

Schedule 13G/A regulatory
"Amendment No. 7 to a Schedule 13G/A reporting beneficial ownership"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
Beneficial ownership regulatory
"Amount beneficially owned: 6,012,000 (b) Percent of class: 9.46%"
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.
Investment Management Agreement financial
"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.
Joint Filing Statement regulatory
"JOINT FILING STATEMENT PURSUANT TO RULE 13d-1(k)"
CUSIP technical
"CUSIP No.: 556099109"
A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.
