Remarks
On August 14, 2026, the reporting persons filed a Form 4 which incorrectly stated the numbers of shares in Columns 4 and 5 in Table 1 with respect to certain Magnetar Funds. The amendment does not change the aggregate number of shares sold by the Magnetar Funds. The prior Form 4 inadvertently listed the sales of shares by (i) CW Opportunity 2 LP when such sales were by Magnetar Constellation Master Fund, Ltd, (ii) CW Opportunity LLC when such sales were by CW Opportunity 2 LP, (iii) Longhorn Special Opportunities Fund LP when such sales were by CW Opportunity LLC, (iv) Magnetar Constellation Master Fund, Ltd when such sales were by Magnetar Lake Credit Fund LLC, (v) Magnetar Lake Credit Fund LLC when such sales were by Magnetar Structured Credit Fund, LP DBA Magnetar Constellation Onshore Fund (They are not separate legal entities), (vi) Magnetar Structured Credit Fund, LP DBA Magnetar Constellation Onshore Fund (They are not separate legal entities) when such sales were by Purpose Alternative Credit Fund - T LLC and (vii) Purpose Alternative Credit Fund - T LLC when such sales were by Longhorn Special Opportunities Fund LP. This amended Form 4 is being filed for purposes of correcting this misstatement and listing the correct number of shares sold by each Magnetar Fund. The reporting persons are restating the entire initial Form 4's transactions.
