FAQ

What insider transactions did BlackSky (BKSY) report for CFO Henry Edward Dubois?

The filing shows CFO Henry Edward Dubois received 77,083 restricted stock units and had 23,551 shares withheld to cover tax obligations on vested RSUs. These events are compensation-related, not open-market trading, and adjust his direct equity stake in BlackSky.

How many RSUs were granted to the BlackSky (BKSY) CFO in this Form 4?

The CFO received a grant of 77,083 restricted stock units, each representing one share of Class A Common Stock. The RSUs vest over several years, beginning in March 2027, and depend on him remaining a service provider through each vesting date.

Why were 23,551 BlackSky (BKSY) shares disposed of in this Form 4?

The 23,551 shares were withheld by BlackSky to satisfy tax withholding and remittance obligations for vested RSUs. The filing specifies this is not a market transaction, but an automatic tax-withholding disposition related to equity compensation, rather than a discretionary sale.

What is the vesting schedule for the new BlackSky (BKSY) RSUs granted to the CFO?

The RSUs vest over time: one-fourth of the 77,083 units will vest on March 10, 2027. The remaining units vest in equal one-sixteenth portions quarterly on March 10, June 10, September 10 and December 10, subject to continued service with BlackSky.

How many BlackSky (BKSY) shares does the CFO hold after these transactions?

After the RSU grant and related tax withholding, the CFO directly holds 439,822 shares of BlackSky Class A Common Stock. This figure reflects his position following the 23,551-share tax-withholding disposition recorded in the Form 4 and the new RSU-related acquisition.

Does this BlackSky (BKSY) Form 4 show any open-market stock sales by the CFO?

The filing does not report open-market sales. Instead, it records a grant of 77,083 RSUs and the withholding of 23,551 shares to cover tax obligations on vested RSUs, which the footnote explicitly states is not a market transaction involving discretionary selling.
