Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 4 footnotes

Footnote F1

Represents the number of shares sold to cover the statutory tax withholding obligations in connection with the vesting of Restricted Stock Units (RSUs) and does not represent a discretionary sale by the Reporting Person. The "Amount" and "Price" reported in this Column 4 reflect the aggregate number and weighted-average price, respectively, of shares sold.

Footnote F2

Certain of these securities are RSUs. Each RSU represents a contingent right to receive one share of Class A Common Stock, subject to the applicable vesting schedule and conditions of each RSU.

Footnote F3

The Form 4 filed on September 15, 2025 (the "Original Form 4") and the Form 4/A filed on October 17, 2025 (the "Original Form 4/A") erroneously reflected an incorrect vesting schedule. One third (1/3rd) of the RSUs are scheduled to vest on September 10, 2026, and thereafter, one twelfth (1/12th) of the total number of RSUs are scheduled to vest quarterly on the 10th day of the third month of each quarter (March 10, June 10, September 10, December 10), subject to the named executive officer continuing to be a service provider through the applicable vesting date. The Amount of Securities Beneficially Owned Following Reported Transactions represented on the Original Form 4 and the Original Form 4/A was correctly reported.

Footnote F4

This holding report is reflected solely to clarify the vesting schedule set forth in the Form 4 filed on March 12, 2025. Each Option represents a right to purchase the underlying securities of the Issuer reported in Table II. The options are granted pursuant to the BlackSky Technology Inc. 2021 Equity Incentive Plan. The number of options and exercise price for the options was calculated based on the closing price of a share of BlackSky Technology Inc.'s Class A Common Stock on the New York Stock Exchange on March 10, 2025. One third (1/3rd) of the award vests on March 10, 2026, and thereafter, one thirty-sixth (1/36th) of the award vests or is scheduled to vest monthly on the 10th day of each month, subject to the Reporting Person continuing to be a service provider through the applicable vesting date.
