Biodesix (BDSX) CCO Kieran O'Kane Receives RSUs, Sells 584 Shares

What happened

Kieran O'Kane, Chief Commercial Officer of Biodesix (BDSX), had 1,600 restricted stock units (RSUs) convert to common stock on 2026-02-09. Per the filing, 1,600 shares were used to satisfy tax withholding (reported as dispositions of 1,527 and 73 shares), and on 2026-02-10 O'Kane sold 584 shares in the open market at $10.08 per share, generating $5,889 in proceeds.
These were not purchases (not a bullish signal): the primary activity was vesting of RSUs and routine sales/withholding related to taxes.
