On November 3, 2026, CSG Space a.s. entered into the Swap (as defined in Item 6). No common shares or other securities of the Issuer were acquired by the Reporting Persons in connection with the Swap or are being pledged as collateral under the Swap. The initial exchange amount, any interim exchange amounts, the up-front fee and any collateral or other cash amounts payable by CSG Space a.s. under the Swap have been or will be funded with working capital of Czechoslovak Group a.s.

CSG Space a.s. entered into the Swap to obtain additional economic exposure to the common shares of the Issuer as part of the Reporting Persons' long-term strategic investment in the Issuer. The Swap provides solely for cash settlement and does not give the Reporting Persons the right to acquire, vote or direct the voting of, or dispose of or direct the disposition of, any securities of the Issuer. On October 13, 2026, Czechoslovak Group a.s. issued a press release announcing its investment in the Issuer, in which it stated, among other things, that it intends to be a long-term strategic shareholder of the Issuer and views its investment as an opportunity to explore potential cooperation between Czechoslovak Group a.s. and the Issuer over time. The press release stated that such cooperation could include co-investing in manufacturing or assembly facilities in Europe, partnering on strategic acquisitions, and otherwise seeking to introduce Czechoslovak Group a.s.'s customer relationships to the Issuer to support the Issuer's international growth. Czechoslovak Group a.s. also announced the creation of a dedicated space team to develop its activities in the space sector. In connection with the foregoing, the Reporting Persons and their representatives may from time to time engage in discussions with the Issuer's management and board of directors, other shareholders of the Issuer and other relevant parties regarding potential commercial, industrial or strategic cooperation, including the matters described above, which may relate to or result in one or more of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including an extraordinary corporate transaction involving the Issuer or any of its subsidiaries. As of the date hereof, no agreement, arrangement or understanding with respect to any such cooperation has been reached, and there can be no assurance that any such cooperation will be pursued or consummated. Under the terms of the Swap, CSG Space a.s. has agreed that, during the term of the Swap and without the prior written consent of the Counterparty (as defined in Item 6), it will not purchase or sell, or enter into any derivative transaction referencing, equity securities of the Issuer, and will not announce, commence or engage in a tender offer or take-over bid for the common shares of the Issuer. Except as set forth herein, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Subject to the terms of the Swap and applicable law, the Reporting Persons intend to review their investment in the Issuer on a continuing basis and may, at any time and from time to time, change their plans or intentions with respect to the Issuer and take such actions with respect to their investment in the Issuer as they deem appropriate.

The percentage of common shares beneficially owned by each of the Reporting Persons reported herein is based upon 162,063,406 common shares outstanding as reported on the Issuer's Current Report on Form 6-K, filed with the SEC on August 7, 2026. As of the date hereof, each of CSG Space a.s., Czechoslovak Group a.s. and Mr. Strnad may be deemed to beneficially own 15,356,219 Shares, constituting approximately 9.5% of the common shares outstanding. Upon its entry into the Swap described in Item 6, the Counterparty had not commenced establishing its hedge positions, the Swap did not reference any common shares of the Issuer, and CSG Space a.s. had no economic exposure to common shares of the Issuer under the Swap. The number of common shares referenced in the Swap may increase during the initial hedging period. The Reporting Persons intend to amend this Schedule 13D to report the final number of common shares referenced in the Swap following the end of the initial hedging period or as otherwise required. Because the Swap is settled solely in cash and does not confer voting or dispositive power over, or the right to acquire, any common shares of the Issuer, the Reporting Persons do not beneficially own, and expressly disclaim beneficial ownership of, the common shares referenced in the Swap, and such shares are not included in the amounts reported on the cover pages or in this Item 5. Each of CSG Space a.s., Czechoslovak Group a.s. and Mr. Strnad may be deemed to have sole voting and dispositive power over 15,356,219 Shares for purposes of this Schedule 13D.

Each of CSG Space a.s., Czechoslovak Group a.s. and Mr. Strnad may be deemed to have sole power to vote and dispose of the Shares reported herein.

On October 13, 2026, CSG Space a.s. acquired 15,356,219 Shares upon physical settlement of the Share Forward Transaction at the average price of CAD 42.6903 per Share. On November 3, 2026, CSG Space a.s. entered into the Swap described in Item 6, which references a number of common shares of the Issuer with respect to which the Counterparty will establish its initial hedge position, subject to price, volume and other market conditions. The initial price and the settlement price under the Swap described in Item 6 will be based on the weighted average price per share at which the Counterparty establishes its hedge positions and at which the Counterparty unwinds its hedge positions, respectively. Except as set forth herein, none of the Reporting Persons has effected any transaction in the common shares of the Issuer during the past 60 days.

No person other than CSG Space a.s., Czechoslovak Group a.s. and Mr. Strnad is known to have the right to receive, or the power to direct the receipt of, dividends from, or proceeds from the sale of, the Shares.

Not applicable.

On November 3, 2026, CSG Space a.s. entered into a cash-settled share swap transaction (the "Swap") with an international financial institution (the "Counterparty"), as evidenced by a confirmation dated November 3, 2026 between CSG Space a.s. and the Counterparty, which supplements and is subject to the ISDA 2002 Master Agreement deemed entered into between the parties pursuant to the confirmation of the Swap. The Swap references a number of common shares of the Issuer (the "Reference Shares") equal to the number of common shares in respect of which the Counterparty establishes its hedge positions during an initial hedging period, subject to a maximum price per share, daily volume limits and a maximum hedge position percentage. The initial hedging period begins when the Counterparty confirms receipt of the initial exchange amount and ends on the earlier of the date on which the Counterparty completes the establishment of its hedge positions and August 31, 2027 (or such later date as CSG Space a.s. and the Counterparty may agree). The initial hedging period commenced November 3, 2026. The initial price of the Swap is based on the weighted average price at which the Counterparty establishes its hedge positions. The Swap is scheduled to be unwound during a hedge unwind period ending on or about December 31, 2027, which CSG Space a.s. may accelerate by written notice, and terminates on the final cash settlement payment date, subject to early termination in accordance with its terms. Under the terms of the Swap, (i) the Counterparty is obligated to pay to CSG Space a.s. any positive price performance of the Reference Shares, and (ii) CSG Space a.s. is obligated to pay to the Counterparty any negative price performance of the Reference Shares, in each case as calculated in accordance with the Swap. The Counterparty is obligated to pay to CSG Space a.s. amounts equal to cash dividends paid on the Reference Shares and floating amounts on any excess exchange amounts. The Swap provides exclusively for cash settlement, with settlement amounts determined by reference to the weighted average price per share at which the Counterparty unwinds its hedge positions, and does not provide for physical settlement. The Swap does not give the Reporting Persons direct or indirect voting, investment or dispositive power over any securities of the Issuer or any right to acquire any securities of the Issuer. Although the Counterparty may hedge its exposure under the Swap by acquiring common shares of the Issuer on the Toronto Stock Exchange or the New York Stock Exchange, it is not obligated to do so, and the Swap provides that CSG Space a.s. has no right to instruct or influence the Counterparty's exercise of voting rights attached to, or the manner in which it establishes, manages or unwinds, any such hedge positions. Accordingly, the Reporting Persons disclaim beneficial ownership of the Reference Shares and of any securities of the Issuer that the Counterparty may hold or acquire to hedge its exposure under the Swap. The Swap also contains customary representations, warranties and covenants, including covenants by CSG Space a.s. that, during the term of the Swap and without the prior written consent of the Counterparty, it will not purchase or sell, or enter into any derivative transaction referencing, equity securities of the Issuer (other than in connection with the Swap), and will not announce, commence or engage in a tender offer or take-over bid for the common shares of the Issuer. Except as described in this Item 6, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons or between the Reporting Persons and any other person with respect to the securities of the Issuer.

Not applicable.
