AlTi Global (ALTI) CEO Michael Tiedemann Converts RSUs, No Net Change

What Happened

Michael Tiedemann, CEO of AlTi Global (ALTI), exercised/converted derivative awards (reported under code M) on February 15, 2026. He recorded acquisitions of 25,546.28, 57,909.61 and 85,751.98 shares (total 169,207.87) at an exercise/ conversion price of $0.00, and the same amounts were recorded as disposals the same day. The transactions appear to reflect settlement/ conversion of restricted stock units (RSUs) rather than a paid purchase; there was no cash paid or received shown in the filing and no net change in beneficial ownership.

Key Details

Shares acquired and disposed (same day): 25,546.28; 57,909.61; 85,751.98 — total 169,207.87 shares.

Context

These were derivative/RSU conversions (code M). Because the exercise/conversion price is $0 and the acquisitions and disposals occurred the same day, the filing likely documents settlement of vested RSUs and a corresponding disposition of the derivative position (e.g., transfer, settlement or withholding). The filing does not show an open-market sale or cash proceeds, so it does not signal a typical “sell” or “buy” trade.
