Insights

Equity compensation analyst

Routine RSU grant with automatic tax withholding, no open‑market trading.

Director Helena Helmersson received 1,689 restricted stock units on March 24, 2026, which immediately converted into Class A Shares. This is standard board-level equity compensation, recorded at a transaction price of $0.0000 because it is an award, not a market purchase.

On March 26, 2026, 440 shares were withheld at her election to cover tax obligations from the RSU vesting. The footnote clarifies this was not a discretionary trade, so it carries little informational value about her view of the stock. After these entries, she directly held 3,105 Class A Shares.
