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.

Schedule 13Gregulatory
"form_type: SCHEDULE 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.

Does the Schedule 13G show voting control by Squarepoint in LENZ?
The filing shows shared voting power and shared dispositive power for the reported shares. It lists zero sole voting or sole dispositive power and indicates coordinated, not sole, control over votes.
Who signed the Schedule 13G for the Squarepoint entities?
The Schedule 13G is signed by John Weitzer, Chief Compliance Officer, for the Squarepoint entities. Signature dates shown on the filing are 04/08/2026 for each signature line.
What does 5.08% ownership mean for LENZ shareholders?
A 5.08% stake signals an institutional passive holding size under the Schedule 13G disclosure threshold; the filing reports percentages and shared powers but does not state any active control or intent to influence management.
When would Squarepoint need to change this filing type or update disclosures?
If the position becomes active or ownership crosses regulatory thresholds requiring different reporting, Squarepoint would move from Schedule 13G to other forms. The filing itself does not specify future timing; updates appear in subsequent SEC filings.
