On December 13, 2024, pursuant to the Securities Purchase Agreement dated July 14, 2024 between SKT and the Issuer (the "Purchase Agreement"), Astra purchased the Preferred Shares from the Issuer for $200 million. Such consideration was paid out of the general operating funds of SKT. Astra may convert the Preferred Shares into Ordinary Shares at any time, provided that the Preferred Shares may, at the Issuer's option, automatically be converted into Ordinary Shares on any date following the second anniversary of the closing upon which the volume-weighted average price of the Ordinary Shares for any fifteen consecutive trading day period equals or exceeds 150% of the then-applicable conversion price. The Preferred Shares are convertible into Ordinary Shares at an initial conversion price of $32.80784 per Ordinary Share, subject to customary adjustment upon the occurrence of certain events (including share subdivision and consolidation, certain dividends and distributions, and any reclassification or share exchange) and a share issuance limitation. The Preferred Shares entitle Astra to receive dividends of six percent (6%) per annum, cumulative, and payable quarterly in-kind or in cash at the Issuer's option, subject to certain conditions.

The information set forth in Item 6 of this Schedule 13D is hereby incorporated by reference. The Reporting Persons acquired the Preferred Shares reported in this Schedule 13D pursuant to the Purchase Agreement for investment purposes. In addition to the Purchase Agreement, Astra and the Issuer have entered into an Investor Agreement dated as of December 13, 2024 (the "Investor Agreement"), which has been summarized in Item 6 below. The Reporting Persons will continually review their investment in the Issuer, including evaluations of the Issuer's business, strategies, prospects, management, governance, operations, performance, financial matters, capital structure, prospects, strategic and other transactions, as well as alternative investment opportunities, changes in law and/or regulations, general industry or economic conditions and all other factors that may be deemed relevant in determining whether additional securities of the Issuer will be acquired by the Reporting Persons or whether the Reporting Persons will dispose of any securities of the Issuer. Depending on such and other factors, at any time and subject to the terms of the Investor Agreement, the Reporting Persons may acquire additional securities of the Issuer (in addition to the Preferred Shares), or, at any time, some or all of the Preferred Shares or other securities beneficially owned by the Reporting Persons may be sold, in each case in the open market, in privately negotiated transactions, in other strategic or extraordinary transactions, or otherwise. Except as described herein, the Reporting Persons do not have any current plans or proposals which relate to or would result in any of the actions described in Items 4(a)-(j) of Schedule 13D; provided, that the Reporting Persons may, at any time, review or reconsider their position with respect to the Issuer and reserve the right to develop such plans or proposals.

All percentages set forth in this Item 5 were calculated in accordance with Rule 13(d)-3(d)(1)(i) promulgated under the Act, which requires the assumption that the Reporting Persons have converted the Preferred Shares into Ordinary Shares. The percentages calculated are based on 53,289,867 shares of Ordinary Shares outstanding as set forth in the Issuer's most recent Form 10-K. The information in the cover pages of this Schedule 13D is incorporated by reference.

Astra has the sole power to vote and the sole power to dispose of the Preferred Shares and the 6,096,103 Ordinary Shares issuable upon conversion of the Preferred Shares, subject to the Investor Agreement described in Item 6 of this Schedule 13D. Astra is a special purpose vehicle established by SKT to invest in the Issuer.
