Insights
Armistice reports a sub-5% passive stake via a managed fund.
Armistice Capital discloses beneficial ownership of 679,033 shares (4.99%), held directly by Armistice Capital Master Fund Ltd. and managed under an Investment Management Agreement. The filing classifies the position as ownership of 5 percent or less of the class.
The statement clarifies voting and dispositive power are exercised by Armistice Capital under the management agreement and that the Master Fund disclaims direct beneficial ownership attributable to its lack of voting/dispositive rights. Subsequent filings would show any material changes to percentage ownership.
The amendment is a routine Schedule 13G/A disclosure with joint-filing language.
The document includes a joint filing statement pursuant to Rule 13d-1(k), attributing responsibility for amendments to the Reporting Persons. It reiterates address, CUSIP 231269309, and the issuer's principal office address in Lexington, MA.
Because the position is reported at 4.99%, the filing aligns with passive/beneficial ownership disclosure conventions under Rule 13G; no change-of-control or activist intent is stated in this excerpt.

"Amendment No. 3 to 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.
Investment Management Agreementfinancial
"Armistice Capital exercises voting and investment power under an Investment Management Agreement"
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.
Beneficial ownershipregulatory
"Amount beneficially owned: 679,033 and percent of class: 4.99%"
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.
