@ $10.38
Significance 3

Peter Yu, then-CEO of Cartesian Growth Corp III, acquired 6,089 shares at $10.38 via private placement on 2026-05-21.

Peter Yu, who held the title of Chairman and CEO at the time of this transaction, acquired 6,089 shares at $10.38 in a private placement on 2026-05-21, bringing his total holdings to 1,468,894 shares. This transaction represents a net change of +0.4% to his pre-transaction holdings. The current price stands at $9.86, and the stock is -5.6% from its 52-week high of $10.44. Because this is a private placement allocation—not a discretionary open-market purchase—it should not be interpreted as a signal of insider conviction or a buying opportunity based on valuation assessment. The transaction reflects a structured capital event rather than a voluntary market timing decision.

Significance 4

Peter Yu, then-CEO, acquired 200,000 shares (200.0K shares) for $2,065,100.00 via private placement at blended average $10.33

Peter Yu, who was Chairman and CEO at the time, participated in 2 separate purchases totaling 200,000 shares (200.0K shares) for $2,065,100.00 ($2.1M) at an average price of $10.33 per share, increasing his holdings from 1,271,000 shares (1.27M shares) to 1,471,000 shares (1.47M shares), a net increase of 15.7%. The FLAG indicates this was a private placement, PIPE, registered direct, or IPO allocation—not a discretionary open-market purchase. As a non-discretionary transaction, this acquisition should not be interpreted as a buying signal driven by insider conviction, but rather as participation in a structured capital event at Cartesian Growth Corp III.

Significance 4

CGCT Chairman/CEO Peter Yu acquires 300,000 shares for $3,091,400.00 in 3 private placements, raising holdings to 1,271,000 shares

Peter Yu, then-CEO and Chairman of Cartesian Growth Corp III, completed three separate purchases totaling 300,000 shares (300.0K shares) for $3,091,400.00 at an average price of $10.30 across April 6-8, 2026. This transaction is a private placement or PIPE allocation—not a discretionary open-market purchase—so it does not reflect conviction-driven investment activity. The acquisition increased Yu's holdings from 971,000 shares to 1,271,000 shares, a net increase of 30.9% relative to his pre-transaction holdings. Because the FLAG identifies this as a structured investment vehicle transaction rather than a signal from open-market accumulation, the filing reflects capital commitment mechanics within a SPAC or similar investment structure rather than insider sentiment about the company's near-term prospects.

Significance 3

Peter Yu, then-CEO, bought 971,000 shares in private placement for $9,993,729.00 (blended avg $10.29)

Peter Yu, who was Chairman and CEO at the time of filing, completed 2 separate purchases totaling 971,000 shares for $9,993,729.00 in a private placement transaction dated March 31 – April 1, 2026. This is a structured allocation, not a discretionary open-market purchase, and therefore should not be interpreted as a market-driven buying signal or indicator of insider conviction. The transaction established his initial equity stake in CGCT post-allocation. Private placements serve capital-raising and distribution purposes rather than reflecting an insider's independent assessment of value.
