Purple Biotech Ltd. reports beneficial ownership filings by Mitchell P. Kopin, Daniel B. Asher and Intracoastal Capital LLC showing 282,513,535 Ordinary Shares issuable upon exercise of an Intracoastal warrant, representing 9.99% of the class.
The filing states the 9.99% figure is based on 2,545,449,780 Ordinary Shares outstanding as of March 18, 2026 plus the 282,513,535 shares issuable on the Intracoastal Warrant. A blocker provision prevents exercise of an additional 117,486,465 shares that would otherwise increase beneficial ownership to 400,000,000.

Insights
Filing documents a near-10% potential stake through a warrant with an anti-dilution blocker.
The report shows 282,513,535 Ordinary Shares are issuable upon exercise of the Intracoastal Warrant and that this amount equals 9.99% using the issuer's reported 2,545,449,780 shares outstanding as of March 18, 2026. The filing attributes these economic interests to Mr. Kopin, Mr. Asher and Intracoastal.
The Intracoastal Warrant contains a blocker provision that prevents exercise to the extent it would result in beneficial ownership above 9.99%; without that provision the filing says beneficial ownership could be 400,000,000 shares. Subsequent disclosures or exercises would change the position; timing and cash-flow treatment are not stated in the excerpt.

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.
What stake does PPBT filing show for Kopin, Asher and Intracoastal?
The filing reports 282,513,535 shares issuable on a warrant, representing 9.99% of the class based on 2,545,449,780 shares outstanding as of March 18, 2026. The figure reflects the blocker limitation in the warrant.
How does the Intracoastal warrant's blocker provision affect ownership?
The warrant contains a blocker provision preventing exercise to the extent it would raise ownership above 9.99%. The filing states 117,486,465 shares are excluded due to that blocker.
What would ownership be without the blocker provision?
The filing indicates that without the blocker provision each Reporting Person may have been deemed to beneficially own 400,000,000 Ordinary Shares based on the same outstanding share base cited.
What outstanding share count does the filing use to calculate 9.99%?
The calculation uses 2,545,449,780 Ordinary Shares outstanding as of March 18, 2026, plus the 282,513,535 shares issuable on the Intracoastal Warrant to reach the reported 9.99%.
