**DEREGISTRATION OF SECURITIES** 

This Post-Effective Amendment (the "Post-Effective Amendment") is being filed by Blacksky Technology Inc. (the "Registrant"), to withdraw and remove from registration all of the unsold securities under the following Registration Statement on Form S-3 (Registration No. 333-267889) (the "Registration Statement"), which was previously filed by the Registrant with the U.S. Securities and Exchange Commission (the "SEC") on October 14, 2022 as amended on December 13, 2022, and declared effective by the SEC on December 15, 2022, registering the offer and sale from time to time of up to $200,000,000 of the Registrant's securities.

The Registrant has determined that it has obtained well-known seasoned issuer status subsequent to filing the Registration Statement and is now eligible to register its securities under a new registration statement on Form S-3ASR (the "New Registration Statement"). In connection with the Registrant filing the New Registration Statement, all offers and sales of the Registrant's securities registered pursuant to the Registration Statement are being terminated. Accordingly, pursuant to the undertaking contained in the Registration Statement to remove from registration by means of a post-effective amendment any of the securities which remain unsold at the termination of the offering, the Registrant hereby terminates the Registration Statement in respect of any securities that remain unsold and deregisters all securities that remain unsold under the Registration Statement.
