The filing states 90,475 shares are issuable upon exercise of Intracoastal Warrant 1 and that this equals 5.9% based on 1,445,029 shares outstanding as of January 29, 2026. Two additional warrants for 3,472 shares each are subject to blocker provisions limiting exercise above 4.99%.
Cashflow treatment and any exercise timing are not described in the excerpt; subsequent filings would show whether these warrants are exercised and whether ownership percentages change.
Shared voting and dispositive power is disclosed; reporting persons list shared control of 90,475 shares.
The table shows 0 sole voting power and 90,475 shared voting power, indicating collective control rather than individual sole control. The filing attributes beneficial ownership to the three Reporting Persons acting together.
Blocker provisions on two warrants cap potential additional exercises at 4.99%; governance effects depend on whether exercises occur and on any future amendments to those provisions.

"As of the close of business on March 31, 2026, each of the Reporting Persons may have been deemed to have beneficial ownership"
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.
