The number of shares was calculated in accordance with the formula in the Merger Agreement based on (a) the sum of Horizon Kinetics' tangible net assets of approximately $250 million and the value of Horizon Kinetics' operating business of $200 million, (b) divided by 25. These shares were issued to the members of Horizon Kinetics. As a result, immediately after the effective time of the Merger, SLGD legacy shareholders collectively held approximately 3.5% of the shares of the Company’s common stock outstanding at such time. The Company accounted for the Merger as a reverse acquisition. As such, Horizon Kinetics is considered the accounting acquirer. Therefore, Horizon Kinetics’ historical financial statements are the historical financial statements following the completion of the Merger, and the results of operations of the post-merger company are included in our financial statements for all periods subsequent to August 1, 2024.

The accompanying unaudited interim Condensed Consolidated Financial Statements of Horizon Kinetics Holding Corporation, a Delaware Company (along with its wholly-owned subsidiaries, collectively referred to as the “Company”, “HKHC” or in the first-person notations of “we”, “us” and “our”) were prepared in accordance with accounting principles generally accepted in the United States of America and the interim financial statement rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, these statements include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Condensed Consolidated Financial Statements. The interim operating results are not necessarily indicative of the results for a full year or for any interim period. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations relating to interim financial statements. The accompanying Condensed Consolidated Statement of Financial Condition as of December 31, 2023 has been derived from the Company's annual financial statements for the year ended December 31, 2023. The Condensed Consolidated Financial Statements included herein should be read in conjunction with the audited consolidated financial statements and accompanying notes of Horizon Kinetics, LLC and Subsidiaries included in our Form DEF 14A filed with the SEC on May 13, 2024.

The Condensed Consolidated Financial Statements include the accounts of HKHC and all of its wholly-owned subsidiaries (Horizon Kinetics Asset Management LLC, Kinetics Funds Distributor LLC, KBD Securities LLC and SLG Chemicals, Inc.). All intercompany balances and transactions have been eliminated in consolidation.

On August 1, 2024, the Company, formerly known as “Scott’s Liquid Gold-Inc.,” completed its previously announced merger in accordance with the terms and conditions of the Agreement and Plan of Merger, dated December 19, 2023, as amended (collectively, the “Merger Agreement”), by and among Scott’s Liquid Gold-Inc., a Colorado corporation (“SLGD”), Horizon Kinetics, LLC, a Delaware limited liability company (“Horizon Kinetics”), and HKNY One, LLC, a Delaware limited liability company and wholly owned subsidiary of SLGD (“Merger Sub”). In accordance with the Merger Agreement, Merger Sub merged with and into Horizon Kinetics, with Horizon Kinetics surviving the merger as a wholly-owned subsidiary of the Company (the “Merger”).

In the Merger, all of the ownership interests in Horizon Kinetics were converted into an aggregate of 17,984,253 shares of the Company’s common stock (representing 96.5% of the shares of the Company’s common stock outstanding immediately after the effective time of the Merger). The number of shares was calculated in accordance with the formula in the Merger Agreement based on (a) the sum of Horizon Kinetics' tangible net assets of approximately $250 million and the value of Horizon Kinetics' operating business of $200 million, (b) divided by 25. These shares were issued to the members of Horizon Kinetics.
