Business and Organization	Business and Organization Great Ajax Corp., a Maryland corporation (“Great Ajax” or the “Company”), is an externally managed real estate investment trust (“REIT”) formed on January 30, 2014, and capitalized on March 28, 2014, by its then sole stockholder, Aspen Yo (“Aspen”), an affiliate of Aspen Capital. The Company operates as a mortgage REIT. Historically, the Company primarily targeted acquisitions of (i) re-performing loans (“RPLs”), which are residential mortgage loans on which at least five of the seven most recent payments have been made, or the most recent payment has been made and accepted pursuant to an agreement, or the full dollar amount, to cover at least five payments has been paid in the last seven months and (ii) non-performing loans (“NPLs”), which are residential mortgage loans on which the most recent three payments have not been made. The Company acquired RPLs and NPLs either directly or in joint ventures with institutional accredited investors. The joint ventures were structured as securitization trusts, from which the Company acquired debt securities and beneficial interests. On June 11, 2024, the Company completed its previously announced strategic transaction with Rithm Capital Corp. (together with its subsidiaries, “Rithm” and such transactions together, the “Strategic Transaction”). The Strategic Transaction included a Securities Purchase Agreement entered into by the Company, the Operating Partnership (as defined herein), Thetis Asset Management LLC (the “Former Manager”) and Rithm (the “Securities Purchase Agreement”) on February 26, 2024 which provided for, upon the approval of the Company’s stockholders on May 20, 2024, (i) the sale of $14.0 million of the Company’s common stock to Rithm at a price of $4.87 per share (which represents the trailing five-day average closing price of the Company’s common stock on the New York Stock Exchange (“NYSE”) as of the date of the Securities Purchase Agreement and (ii) a new management agreement (as maybe amended, modified or supplemented from time to time, the “Management Agreement”) with RCM GA Manager LLC, an affiliate of Rithm (“RCM GA” or the “New Manager”), under which, RCM GA became the Company’s new external manager. Additionally, on February 26, 2024, the Company entered into a term loan with Rithm (the “Credit Agreement”), the draw period for which has expired. Entry into the Credit Agreement was accompanied by the Company’s agreement to issue detachable warrants to purchase shares of the Company’s common stock to Rithm. The Company issued such warrants to Rithm to purchase 6.5 million shares with an exercise price of $5.36 per share on May 14, 2024 (the “Rithm Warrants”). See Note 8 — Commitments and Contingencies. On February 26, 2024, the Company issued a termination notice to its Former Manager in connection with the Strategic Transaction and on June 11, 2024, the Company terminated the Former Management Agreement (as defined herein), entered into a termination and release agreement with the Former Manager and issued approximately 3.2 million shares of common stock to the Former Manager in connection with the termination of the Former Manager. For a full description of the components of the Strategic Transaction, see the Company’s Definitive Proxy Statement filed with the Securities and Exchange Commission on April 10, 2024. In connection with the Strategic Transaction, the Company terminated its agreement with Gregory Funding LLC (“Gregory” or “Former Servicer”), the former loan servicer for the Company and disposed of its interest in Great Ajax FS LLC (“GAFS”), the parent company of Gregory. On June 1, 2024, Gregory assigned all of the servicing agreements for its mortgage loans and real property (the “Servicing Agreements”) to Newrez LLC (“Newrez” or “Servicer”), an affiliate of Rithm through a Servicing Transfer Agreement by and between Gregory and Newrez (the “Servicing Transfer Agreement”). The terms of the Servicing Agreements otherwise remain unchanged. The Company conducts substantially all of its business through its operating partnership, Great Ajax Operating Partnership L.P., a Delaware limited partnership (the “Operating Partnership”), and its subsidiaries. The Company, through a wholly-owned subsidiary, Great Ajax Operating LLC, is the sole general partner of the Operating Partnership. GA-TRS LLC (“GA-TRS”) is a wholly-owned subsidiary of the Operating Partnership that owns the equity interest in the Former Manager and previously owned an equity interest in the Former Servicer. GAJX Real Estate Corp. (“GAJX”) is a wholly owned subsidiary of the Operating Partnership formed to own, maintain, improve and sell REO properties purchased by the Company. The Company elected to treat GA-TRS and GAJX as taxable REIT subsidiaries (“TRS”) under the Internal Revenue Code.
