Management concluded that these businesses represent a strategic shift that had a major effect on our operations and met the criteria for discontinued operations and, as such, have been excluded from continuing operations in the periods presented as more fully described in Note 4. Net (loss) income per share amounts are computed independently for net (loss) income from continuing operations, net (loss) income from discontinued operations and net loss attributable to the Company. As a result, the sum of per-share amounts may not equal the total. Unless otherwise indicated, information in these notes to consolidated financial statements relates to continuing operations.

From March 26, 2025 to July 11, 2025, the Company completed five private exchange transactions with institutional investors pursuant to which approximately $115,800 of aggregate principal amount of the Company’s 5.50% Senior Notes due March 2026, approximately $2,100 aggregate principal amount of 6.50% Senior Notes due September 2026, approximately $146,400 aggregate principal amount of the Company’s 5.00% Senior Notes due December 2026, approximately $51,100 aggregate principal amount of the Company’s 6.00% Senior Notes due January 2028, and approximately $39,500 aggregate principal amount of the Company’s 5.25% Senior Notes due August 2028 (collectively, the “Exchanged Notes”) owned by the investors were exchanged for approximately $228,400 aggregate principal amount of newly-issued 8.00% Senior Secured Second Lien Notes due 2028 (the “New Notes”), whereupon the Exchanged Notes were cancelled.

The Company believes that the current cash and cash equivalents, securities and other investments owned, funds available under our credit facilities, cash expected to be generated from operating activities and proceeds received from the Atlantic Coast Transaction, the Wealth Management Transaction and the sale of the Company’s financial consulting business will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months from issuance date of the accompanying financial statements.
