BlackSky (BKSY) CEO Brian O'Toole Receives RSU Award; 25k Shares Withheld

What Happened

Brian E. O'Toole, CEO, President and Director of BlackSky Technology (BKSY), was granted 191,666 restricted stock units (RSUs) on March 10, 2026 (recorded as an acquisition at $0.00 per share). On March 11, 2026, 24,999 shares were withheld to satisfy tax withholding obligations related to the net settlement of vested RSUs; those withheld shares are reported as disposed at $24.00 each for a total of $599,976.
The RSU grant is an award (not a market purchase), and the withholding was done by the issuer to cover taxes — not an open-market sale.

Context

RSUs are awards that convert into shares if and when they vest; this entry mainly reflects a grant and routine tax withholding. The withheld shares were used to satisfy tax obligations and should not be read as an open-market sale signaling sentiment. Grants are common for executives and are not the same as buying stock with personal funds.
