GRI Bio, Inc. share ownership is updated by three reporting persons — Mitchell P. Kopin, Daniel B. Asher, and Intracoastal Capital LLC — who jointly report beneficial ownership of 93,005 shares of common stock as of June 30, 2026. This stake equals approximately 4.99% of the common stock, calculated using 1,770,838 shares outstanding as of May 12, 2026 plus shares issuable under certain warrants. The position consists of 90,475 shares issuable upon exercise of Intracoastal Warrant 1 and 2,530 shares issuable upon exercise of Intracoastal Warrant 2. All 93,005 shares are held with shared voting and dispositive power and no sole power. Additional warrant shares are subject to blocker provisions that prevent exercises resulting in beneficial ownership above 4.99%, so 942 shares from Intracoastal Warrant 2 and 3,472 shares from Intracoastal Warrant 3 are excluded from the reported amount. Without these blockers, total beneficial ownership could be 97,419 shares.

beneficial ownershipfinancial
"may have been deemed to have beneficial ownership of 93,005 shares of Common Stock"
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.
blocker provisionfinancial
"contains a blocker provision under which the holder thereof does not have the right"
warrantfinancial
"shares of Common Stock issuable upon exercise of a warrant held by Intracoastal"
A warrant is a time-limited financial contract that gives its holder the right to buy a company's shares at a set price before a specified date, like a coupon that lets you purchase stock at a fixed discount for a limited time. It matters to investors because warrants offer leveraged exposure to a stock’s upside and can dilute existing shareholders if exercised, so they affect potential gains and the company’s outstanding share count.
shared voting powerfinancial
"Shared Voting Power 93,005.00"
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.
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

What is the role of blocker provisions in the GRI Bio (GRI) warrants?
Blocker provisions limit exercises that would push ownership above 4.99% of GRI Bio’s common stock. Because of these limits, 942 shares from Warrant 2 and 3,472 shares from Warrant 3 are excluded from the reported beneficial ownership.
Could the GRI Bio (GRI) reporting persons own more than the 93,005 shares disclosed?
Without the blocker provisions, they state they may be deemed to beneficially own 97,419 shares. However, due to the 4.99% ownership limiter in the warrants, only 93,005 shares are included in the reported beneficial ownership.
