Holders may convert their Convertible Senior Notes at their option at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

The conversion rate of the notes will initially be 27.1909 shares of BlackSky’s Class A common stock per $1,000 principal amount of Convertible Senior Notes (equivalent to an initial conversion price of approximately $36.78 per share of Class A common stock). The conversion rate is subject to adjustment upon the occurrence of certain events set forth in the indenture governing the terms of the Convertible Senior Notes. The Company may not redeem the Convertible Senior Notes prior to August 4, 2028. The Company may redeem for cash all or any portion of the Convertible Senior Notes, at the Company's option, on or after August 4, 2028 and prior to the 26th scheduled trading day immediately preceding the maturity date, if (1) the last reported sale price of the Company's Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending

on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption and (2) certain liquidity conditions are satisfied, at a redemption price equal to 100% of the principal amount of the Convertible Senior Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a make-whole fundamental change or our issuance of a notice of redemption, the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert such Convertible Senior Notes in connection with such make-whole fundamental change or notice of redemption.

Satellite Launch Vendor Financing

The Company entered into a vendor financing agreement to fund the costs of multiple satellite launches providing for $27.0 million, for which payments accrue interest at 12.6% per annum.
