Insights
Institutional holder disclosed a passive beneficial stake just above 5%.
This Schedule 13G reports a 5.6% beneficial ownership position held by funds advised by Anson entities, using the issuer's March 31, 2026 outstanding share count of 222,773,999. The filing attributes shared voting and dispositive power across the advisory and management entities.
Because the filing is a 13G-style disclosure, the position is presented as an investment holding; subsequent filings would show if the holder changes intent or crosses active-investor thresholds.
Stake size is modest relative to total float and signals a meaningful, but non-controlling, position.
The disclosed 12,457,698 shares equal 5.6% of the issuer's reported outstanding shares. The filing names multiple affiliated entities and individuals with shared voting and dispositive power over the funds' holdings.
Holder decisions will determine future activity; any material change in ownership or intent would require an amended Schedule 13D/13G filing.

Schedule 13Gregulatory
"This Schedule 13G reports beneficial ownership of Ordinary Shares"
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.
Beneficially ownedregulatory
"Amount beneficially owned: This (the "") is being filed on behalf of Anson Funds"
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.
