Insights

Institutional Ownership Analyst

Islet and its CIO report a sizable passive stake: 7.5M shares (7.33%), using the issuer's Feb 27, 2026 outstanding count.

Islet is disclosed as the investment manager for a single account that directly owns the shares; Islet and Joseph Samuels each report shared voting and dispositive power over 7,500,000 shares. The filing references the issuer's Form 20-F for the outstanding-share base of 102,328,004.

As a Schedule 13G, this is a passive ownership report rather than an active acquisition filing; the economic and voting influence will depend on future holder actions and any amendments that might convert this to an active filing if involvement changes.

3 terms

beneficially owned regulatory

"As of April 3, 2026, the Account directly beneficially owned 7,500,000 shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

shared dispositive power regulatory

"Shared Dispositive Power 7,500,000.00"

Schedule 13G regulatory

"This filing relates to shares of Ordinary shares ... (the "Common Stock")"

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.
