Eloxx Pharmaceuticals disclosed that Coastlands-related reporting persons collectively hold 1,250,000 shares of Common Stock, representing 16.51% of the class. The filing states the ownership calculation uses 5,071,935 shares outstanding as of March 12, 2026 and reflects 2,500,000 shares issued on April 27, 2026 upon exercise of pre-funded warrants. The reporting persons state shared voting and dispositive power over 1,250,000 shares and disclaim control-group status and beneficial ownership beyond their pecuniary interest; a 4.99% beneficial ownership limitation for certain pre-funded warrants is noted.

Insights
Coastlands reports a sizable passive stake with shared control flags; governance implications are routine for large investors.
Coastlands and affiliated entities report beneficial ownership of 1,250,000 shares (16.51%) using the issuer's March 12, 2026 outstanding count. The filing states shared voting and dispositive power, which is typical for an LP/GP structure where power is exercised collectively.
Key items to watch in future disclosures include any schedule amendments that change percent ownership, any acquisitions or dispositions, and whether the partnership converts pre-funded warrants beyond stated 4.99% limitations.
The filing disclaims group status and control; legal posture focuses on compliance with Rule 13d-3 definitions.
The reporting persons expressly disclaim membership in a group and broader beneficial ownership except for pecuniary interest. The signature block and Exhibit 99.1 (joint filing agreement) are included to document filing mechanics.
Material legal signals would appear if future amendments assert group formation, increase voting power, or alter the beneficial ownership limitation; none of those changes are stated here.

"Joint filing of Statement on Schedule 13D or 13G"
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.
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.
pre-funded warrantsfinancial
"2,500,000 shares issued on April 27, 2026 to certain holders upon the exercise of pre-funded warrants"
Pre-funded warrants are financial instruments that give investors the right to purchase a company's stock at a set price, but with most or all of the purchase price paid upfront. They function like a coupon or gift card for stock, allowing investors to buy shares later at a fixed price, which can be beneficial if they want to avoid future price increases. This makes them important for investors seeking flexibility and certainty in their investment plans.
shared dispositive powerregulatory
"Shared Dispositive Power 1,250,000.00"
beneficial ownership limitationlegal
"Excludes shares ... in excess of a beneficial ownership limitation of 4.99%"
A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.
