Picton Mahoney Asset Management Increases Position in Cartesian Growth Corporation III to 4.71%

Picton Mahoney Asset Management filed a Schedule 13G/A on April 27, 2026, disclosing a position in Cartesian Growth Corporation III (CGCT). As of the event date on March 31, 2026, the filer reported beneficial ownership of 1,300,000 Class A ordinary shares. This represents a 4.71% ownership stake in the company, based on 27,600,000 shares outstanding as of March 18, 2026. The filing indicates that Picton Mahoney Asset Management has sole voting and dispositive power over all 1,300,000 shares. Notably, this filing serves as an amendment (Amendment No. 2) to their previous disclosures. Because the ownership percentage has fallen to 4.71%, which is below the 5% threshold, the filer has checked the box in Item 5 indicating they now own 5% or less of the class of securities. The reporting person is a Canadian-based investment fund manager filing under Rule 13d-1(b).
