Kakaopay Transaction [Abstract]
Kakaopay Transaction	5. Kakaopay Transaction On April 27, 2023, Siebert entered into a Stock Purchase Agreement with Kakaopay (the “First Tranche Stock Purchase Agreement”), pursuant to which Siebert agreed to issue to Kakaopay Corporation (“Kakaopay”), a company established under the Laws of the Republic of Korea and a fintech subsidiary of Korean-based conglomerate Kakao Corp., 8,075,607 shares of Siebert’s common stock (the “First Tranche Shares” and, such transaction, the “First Tranche”) at a per share price of Two Dollars Fifteen Cents ($2.15), which represented 19.9% of the outstanding equity securities of Siebert on a fully diluted basis (taking into account the issuance of the First Tranche Shares). The First Tranche closed on May 18, 2023 and, in connection therewith, Siebert entered into a Registration Rights and Lock-Up Agreement (the “Registration Rights Agreement”) and a Stockholders’ Agreement (the “Original Stockholders’ Agreement”) with Kakaopay. Concurrent with the execution of the First Tranche Stock Purchase Agreement, Siebert and Kakaopay entered into a second Stock Purchase Agreement (the “Second Tranche Stock Purchase Agreement” and, together with the First Tranche Stock Purchase Agreement, the “Stock Purchase Agreements”), pursuant to which Siebert agreed to issue to Kakaopay an additional 25,756,470 shares of Siebert’s common stock (the “Second Tranche Shares” and, such transaction, the “Second Tranche”) at a per share price of Two Dollars Thirty Five Cents ($2.35), so that Kakaopay would own 51% of the outstanding equity securities of Siebert on a fully diluted basis (taking into account the issuance of the First Tranche Shares and the Second Tranche Shares). On December 19, 2023, Siebert entered into a Termination and Settlement Agreement (the “Settlement Agreement”) with Kakaopay, Kakaopay Securities Corp. (“Kakaopay Securities”), MSCO and certain Gebbia parties named therein. Under the Settlement Agreement, the parties mutually agreed to terminate the Second Tranche Stock Purchase Agreement. The parties terminated the Second Tranche Stock Purchase Agreement after reaching a compromise regarding their disagreement over, among other things, the occurrence of a “Purchaser Material Adverse Effect” in the Second Tranche Stock Purchase Agreement, and the ability of the closing conditions in the Second Tranche Stock Purchase Agreement to be satisfied. Certain related agreements were also terminated, including the Foreign Broker-Dealer Fee Sharing Agreement, dated April 27, 2023, between MSCO and Kakaopay Securities, and the Support and Restrictive Covenant Agreements by certain Gebbia stockholders, each dated April 27, 2023. The parties also agreed (i) to amend and restate the Original Stockholders’ Agreement as described below, (ii) that the Company will pay Kakaopay a fee of $5,000,000 (payable in ten quarterly installments beginning on March 29, 2024) and (iii) to customary releases. Kakaopay continues to own the 8,075,607 shares of the Company’s common stock that it purchased from the Company in May 2023, and Kakaopay agreed to certain standstill restrictions with respect to its ownership of the Company’s common stock, subject to certain conditions. In connection with the foregoing, on December 19, 2023, Siebert entered into an Amended and Restated Stockholders’ Agreement (the “A&R Stockholders’ Agreement”) with Kakaopay, certain stockholders listed on Schedule I thereto and John J. Gebbia (in his individual capacity and as representative of the Gebbia Stockholders (as defined therein)) to amend and restate the Original Stockholders’ Agreement. Under the A&R Stockholders’ Agreement, Kakaopay retains its right to designate one director to the Company’s board of directors, subject to certain conditions, but the additional board designation rights in the Original Stockholders’ Agreement that would have applied following the closing of the Second Tranche have been removed. The A&R Stockholders’ Agreement also, among other things, modifies various specified events requiring the prior written consent of Kakaopay, which provided the Company’s management with additional flexibility to grow the Company with reduced restrictions. The A&R Stockholders’ Agreement also adds tag-along rights in favor of Kakaopay and the Gebbia Stockholders. At the time of the issuance, the total deferred issuance cost of $2,467,000 related to the First Tranche was reclassified as a reduction to “Additional paid-in capital” in stockholders’ equity on the consolidated statements of financial condition. This amount consisted of $318,000 which was recorded within the line item “Prepaid expenses and other assets” on the consolidated statements of financial condition as of December 31, 2022, and $2,149,000 which was incurred during the year ended December 31, 2023. Of the amount incurred during the year ended December 31, 2023, $560,000 was part of non-cash consideration. The Company incurred $5,943,000 for the year ended December 31, 2023 associated with the termination of the transaction with Kakaopay which is recorded in the line item “Transaction termination cost” on the consolidated statements of operations. This amount consisted of the $5,000,000 fee to Kakaopay (payable in ten quarterly installments beginning on March 29, 2024) adjusted for the present value of the payments as of the date of the agreement, as well as legal and other consulting costs associated with the transaction of approximately $1,481,000. The discount rate used for the calculation of the present value of the cash flows was 8.5%. On May 22, 2023, Gloria E. Gebbia issued a warrant to BCW Securities LLC, a Delaware limited liability company (“BCW”), to purchase 403,780 shares of common stock of the Company held by Ms. Gebbia at an exercise price of $2.15 per share. Ms. Gebbia issued the warrant pursuant to that certain agreement, dated March 27, 2023, by and among Ms. Gebbia, the Company and BCW relating to the investment by Kakaopay in the Company. The fair value of the warrant of $560,000 was recorded as non-cash consideration on the consolidated statements of changes in stockholders’ equity and the consolidated statements of cash flows, as well as for the deferred issuance cost related to the First Tranche as described above.
