(“STXD”) is an inactive subsidiary headquartered in Bermuda. ● Gebbia Media, LLC (“GM”) is a Florida limited liability company and provides management and promotion of sports and music talent, as well as in-house production and marketing for the Company. ● Siebert Crypto, LLC (“SCRYP”) is a Delaware limited liability company formed to provide future digital asset-related services. SCRYP has not yet commenced business operations. For purposes of this Report on Form 10-Q, the terms “Siebert,” “Company,” “we,” “us,” and “our” refer to Siebert Financial Corp., MSCO, SNXT, PW, STCH, RISE, STXD, GM, and SCRYP collectively, unless the context otherwise requires. Effective December 2025, the Company formed SCRYP by filing a Certificate of Formation in the State of Delaware. As of March 31, 2026, SCRYP had not commenced any operations. In April 2026, the Company formed Gebbia Holdings, LLC, and Gebbia Sports, LLC, by filing a Certificate of Formation with the Florida Department of State, Division of Corporations. Subsequent to these corporate actions, both Gebbia Media, LLC, and Gebbia Sports, LLC, are wholly owned subsidiaries of Gebbia Holdings, LLC. Gebbia Holdings, LLC, is a wholly owned subsidiary of the Company. - 5 - The Company is headquartered in Miami Beach, FL with primary operations in Florida, New York, and California. The Company has 13 branch offices throughout the U.S. and clients around the world. The Company’s SEC filings are available through the Company’s website at www.siebert.com, where investors can obtain copies of the Company’s public filings free of charge. The Company’s common stock, par value $ 0.01 per share, trades on the Nasdaq Capital Market under the symbol “SIEB.” The Company operates two reportable segments, Financial Services, and Media, Sports and Entertainment. Financial Services is the Company’s primary segment and includes the Company’s broker-dealer and related financial services operations. Media, Sports and Entertainment includes the Company’s entertainment and sports management and related marketing, advertising, and production activities. All of the Company's revenues for the three months ended March 31, 2026 and 2025 were derived from its operations in the U.S . Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“financial statements”) of the Company have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete annual financial statements. The U.S. dollar is the functional currency of the Company and numbers are rounded for presentation purposes. In the opinion of management, the financial statements contain all adjustments (consisting of normal recurring entries) necessary to fairly present such interim results. Interim results are not necessarily indicative of the results of operations which may be expected for a full year or any subsequent period. These financial statements should be read in conjunction with the financial statements and notes thereto in the Company’s 2025 Form 10-K. Reclassification Certain prior year amounts have been reclassified to conform with current year presentation. The reclassification had no impact on previously reported assets or liabilities and did not result in a change in revenue or net income for the periods presented. Principles of Consolidation The financial statements include the accounts of Siebert and its wholly-owned consolidated subsidiaries. Upon consolidation, all intercompany balances and transactions are eliminated. For consolidated subsidiaries that are not wholly-owned, the third-party holdings of equity interests are referred to as noncontrolling interests. The net income or loss attributable to noncontrolling interests for such subsidiaries is presented as net income or loss attributable to noncontrolling interests in the consolidated statements of operations. The portion of total equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests in the consolidated statements of financial condition. For the three months ended March 31, 2026, all subsidiaries are wholly-owned. Significant Accounting Policies The Company’s significant accounting policies are included in Note 2 – Summary of Significant Accounting Policies in the Company’s 2025 Form 10-K. During the three months ended March 31, 2026, except as set forth below, those policies were unchanged during the three months ended March 31, 2026. Clearing Agreement and Warrant Agreement During the first quarter of 2026, RISE entered into a clearing arrangement with Green Pier Fintech LLC (“Green Pier”), an indirect wholly owned subsidiary of Fidelity Management and Research LLC (“FMR”). In connection with the arrangement, on March 2, 2026, RISE issued FMR a warrant to purchase up to 700 LLC units, subject to vesting over three years, and entered into a related side letter. The Company concluded that the warrant, as modified by the side letter, is an equity-classified share-based payment award. Accordingly, the warrant is measured at fair value on the grant date and the warrant is not subject to subsequent remeasurements so long as they continue to meet criteria for equity classification over the requisite service period, with remeasurement at fair value at each reporting date until settlement, expiration, or forfeiture. The clearing arrangement is accounted for separately as an executory service arrangement, and related fees are recognized as incurred. The Company recognizes share-based compensation expense over the nonemployee’s vesting period as services are received. As of March 31, 2026, the Company recognized $ 100,000 of share-based compensation expense related to the warrant, which is included in the line item “Clearing fees, including execution costs” on the statements of operations. - 6 - Investment in Equity Security In the first quarter of 2025, the Company participated in a private placement and acquired restricted shares of a privately held U.S. company (the “Investment in Equity Security”). These shares were subject to restrictions on transferability and did not have a readily determinable fair value at the time of acquisition. On March 31, 2025, the issuer completed its initial public offering “(IPO”), and restricted shares owned by the Company converted into restricted publicly traded shares as part of the IPO process. These shares remained subject to resale restrictions and could not be sold unless a registration statement was filed with SEC or an applicable exemption from registration became available. There was significant volatility in the price of the shares, and in the three months ended March 31, 2025, the Company recorded an unrealized gain of approximately $ 9.2 million as the per share price closed at $ 85.31 on March 31, 2025. In June 2025, after the lifting of contractual sale restrictions, the Company sold the majority of its Investment in Equity Security for an average price of $ 19.00 per share. The Company recognized a gain of $ 2.4 million related to this investment after selling our position. Additional details are provided in the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2025. 2. New Accounting Standards Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), “2024-03”, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures” (“ASU 2024-03”). The ASU is intended to enhance the transparency and decision usefulness of income statement expense disclosures by requiring greater disaggregation of certain expense categories. In January 2025, the FASB issued ASU 2025-01, which clarified the effective date of ASU 2024-03. For public business entities, the amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact that ASU 2024-03 will have on its consolidated financial statements and anticipates the amendments will require significant changes to the Company’s expense disclosures. In September 2025, the FASB issued ASU No. 2025-06, “Intangibles-Goodwill and Other- Internal-Use Software” (“ASU 2025-06”). The ASU is intended to modernize and clarify the threshold for when an entity is required to start capitalizing software costs and is based on when (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 will be effective for the Company for fiscal years beginning after December 15, 2027, and interim reporting periods, with early adoption permitted. The Company is evaluating the impact of the standard on its disclosures. Accounting Standards Adopted in Fiscal 2026 In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments-Credit Losses” (“ASU 2025-05”). The ASU is intended to provide an optional practical expedient when applying the guidance related to the estimation of expected credit losses for current accounts receivable and current contract assets resulting from transactions arising from contracts with customers. ASU 2025-05 will be effective for the Company for fiscal years beginning after December 15, 2025, and interim reporting periods, with early adoption permitted. The Company adopted the standard in the three months ended March 31, 2026 and the adoption of ASU 2025-05 did not have a material impact on its financial statements. Other than the above, the Company did not adopt any new accounting standards during the three months ended March 31, 2026. In addition, the Company has evaluated other recently issued accounting standards and does not believe that any of these standards will have a material impact on the Company’s financial statements and related disclosures as of March 31, 2026. 3. Asset Acquisition On April 30, 2025, the Company acquired certain assets from Big Machine Label Group RLS LLC (“BMLG”) related to music masters, including associated copyrights and artwork. The Company acquired these assets to expand its music business line and this transaction was accounted for as an asset purchase, in accordance with ASC 805, Business Combinations, because substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset which is the recorded masters. The total cost of the acquisition was $ 441,000 , which includes cash consideration of $ 337,000 and direct transaction costs of $ 104,000 . The entire cost was allocated to the recorded masters intangible asset, which is included in the line item “Intangible assets, net” and will be amortized on a straight-line basis over an estimated useful life of 8.5 years, reflecting the contractual licensing periods with the artists. - 7 - The purchase price was allocated as follows: Consideration: Cash payment $ 337,000 Direct transaction costs 104,000 Total consideration $ 441,000 Assets acquired: Recorded masters $ 441,000 Total allocated costs $ 441,000 4.

Leases As of March 31, 2026, all of the Company’s leases are classified as operating and primarily consist of office space leases expiring in 2026 through 2029. The Company elected not to include short-term leases (i.e., leases with initial terms of less than twelve months), or equipment leases (deemed immaterial) on the statements of financial condition. The Company leases some miscellaneous office equipment, but they are immaterial and therefore the Company records the costs associated with this office equipment on the statements of operations rather than capitalizing them as lease right-of-use assets. The balance of the lease right-of-use assets and lease liabilities are displayed on the statements of financial condition and the below tables display further detail on the Company’s leases.

This branch office contains approximately 10,000 square feet of interior and exterior space, and the average annual rent is $ 681,000 . 9. Goodwill and Other Intangible Assets, Net Goodwill As of March 31, 2026 and December 31, 2025, the Company’s carrying amount of goodwill was $ 1,989,000 and $ 2,319,000 , respectively. As of March 31, 2026, $ 1,989,000 of the Company’s carrying amount of goodwill came from the Company’s acquisition of RISE and $ 330,000 came from the Company’s acquisition of GM. During the three months ended March 31, 2026, management identified indicators related to the Media, Sports, and Entertainment reporting unit, including the reporting unit’s operating results, revised outlook, and changes in market capitalization. As a result, the Company performed a quantitative goodwill impairment assessment for the Media, Sports and Entertainment reporting unit. Based on this assessment, management concluded that the carrying amount of the reporting unit exceeded its fair value by an amount greater than the goodwill assigned to the reporting unit. The analysis indicated that the estimated fair value of the reporting unit was below its updated carrying amount as of March 31, 2026. The decline in fair value was primarily attributable to higher start-up, artist-development, marketing, production, personnel, and infrastructure costs than originally anticipated, as well as fewer artist/talent contracts and related revenue-generating opportunities materializing than initially projected. These factors reduced forecasted cash flows and delayed the reporting unit’s expected path to profitability. The discounted cash flow analysis included significant assumptions related to revenue growth, timing of artist/talent contract activity, artist-development and production costs, marketing spend, personnel costs, expected timing of profitability, and the discount rate. The fair value estimate is sensitive to changes in these assumptions, including the timing and amount of future revenue-generating opportunities and the reporting unit’s ability to scale operating costs. - 13 - Accordingly, the Company recorded a noncash goodwill impairment charge of $ 330,000 during the three months ended March 31, 2026, representing the full carrying amount of goodwill assigned to the Media, Sports, and Entertainment reporting unit. The impairment charge is included in the line item “Goodwill impairment” in the statements of operations. The Company also evaluated its Financial Services reporting unit and concluded that no impairment existed as of March 31, 2026. Other Intangible Assets, Net As a result of the Company’s acquisition of GM in 2024, the Company acquired an intangible asset consisting of a GM artist contract, the fair value of which was $ 778,000 as of the acquisition date. Amortization commenced upon acquisition and is recognized over its estimated useful life of 4 years. Amortization expense for this intangible asset was $ 48,000 for both the three months ended March 31, 2026 and 2025. On April 30, 2025, the Company acquired certain assets from BMLG related to music masters, including associated copyrights and artwork. The acquisition was accounted for as an asset purchase, in accordance with ASC 805, Business Combinations, as substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset which is the recorded masters. The entire cost of $ 441,000 was allocated to the recorded masters intangible asset, which is amortized on a straight-line basis over an estimated useful life of 8.5 years, reflecting the contractual licensing periods with the artists. Amortization expense for this intangible asset was $ 13,000 for the three months ended March 31, 2026. As of March 31, 2026, the Company estimates the following future amortization of its intangible assets: Year Amount 2026 $ 39,000 2027 52,000 2028 52,000 2029 52,000 2030 and after 198,000 Total $ 393,000 During the three months ended March 31, 2026, the Company identified indicators of impairment related to the GM artist contract intangible asset associated with the Media, Sports and Entertainment reporting unit, primarily due to changes in the expected economics of the related artist contract and lower-than-expected performance of related revenue opportunities. These factors reduced projected cash flows, and the Company performed a recoverability assessment under ASC 360. Based on the assessment, the Company determined that the carrying amount of the asset was not recoverable and recorded a noncash impairment charge of $ 454,000 , representing the full remaining net carrying amount of the affected asset. The impairment charge is included in “Intangible asset impairment” in the statements of operations, and following the impairment, no remaining carrying value was assigned to the affected asset. 10. Investments, Cost In the second quarter of 2025, the Company made strategic investments for a total of $ 2.0 million in Fusion IQ, a cloud-native digital wealth management platform for financial advisors and institutions. As of March 31, 2026, the Company maintained a 4 % ownership interest in FusionIQ. As part of its investment in FusionIQ, the Company has certain voting rights as protective provisions requiring the Company’s consent to amend the operating agreement, pay dividends, incur indebtedness in excess of $ 750,000 or enter into a related party transaction of $ 100,000 or more. The investment does not have a readily determinable fair value since FusionIQ is a private company and its shares are not publicly traded. Accordingly, the Company elected the measurement alternative under ASC 321, whereby the investment is measured at cost, less impairment, if any, and adjusted for observable price changes in orderly transactions for the identical or similar investment of the same issuer. In December 2025, Fusion IQ issued a convertible promissory note to the Company in the principal amount of $ 350,000 . The note accrues interest at a simple annual rate of 12 % from the date of issuance. The principal balance and accrued interest are payable at any time on or after the one-year anniversary of the issuance date, at the election of FusionIQ or upon demand by the holder, unless earlier converted into equity interests. As of both March 31, 2026 and December 31, 2025, the Company recorded $ 2.0 million in “Investments, cost” and $ 350,000 in “Notes receivables” on the statements of financial condition related to these transactions. As of March 31, 2026, management concluded that its investment in FusionIQ was not impaired and that no additional events or changes in circumstances were identified that could have a significant effect on the original valuation of the investment. In the first quarter of 2026, the Company made a $ 2.5 million investment in Arqitech, Inc. (“Arqitech”), consisting of $ 0.5 million in common stock and $ 2.0 million in debt. Arqitech is an institutional-grade, non-custodial digital asset infrastructure platform that provides on-chain settlement, cross-chain execution, and decentralized financial technology solutions for regulated financial institutions. As part of the investment, the Company expects to receive repayment of $ 2.0 million of debt commencing in July 2026. As of March 31, 2026, the Company recorded $ 0.5 million in “Investments, cost” and $ 2.0 million in “Notes receivables” on the statements of financial condition related to this investment. - 14 - 11. Long-Term Debt Mortgage with East West Bank Overview On December 30, 2021, the Company purchased the Miami office building for approximately $ 6.8 million, and the Company entered into a mortgage with East West Bancorp, Inc. (“East West Bank”) for approximately $ 4 million to finance part of the purchase of the Miami office building as well as $ 338,000 to finance part of the build out of the Miami office building. As of March 31, 2026 and December 31, 2025, the Company’s outstanding balance of the mortgage was $ 4,116,000 and $ 4,140,000 , respectively. The Company’s obligations under the mortgage are secured by a lien on the Miami office building and the term of the loan is ten years . The repayment schedule will utilize a 30-year amortization period, with a balloon on the remaining amount due at the end of ten years. The interest rate is 3.6 % for the first 7 years, and thereafter the interest rate will be at the prime rate as reported by the Wall Street Journal, provided that the minimum interest rate on any term loan will not be less than 3.6 %. As part of the agreement, the Company must maintain a debt service coverage ratio of 1.4 to 1. The loan is subject to a prepayment penalty over the first five years which is calculated as a percentage of the principal amount outstanding at the time of prepayment. This percentage is 5% in the first year and decreases by 1% each year thereafter, with the prepayment penalty ending after 5 years. As of March 31, 2026, the Company was in compliance with all of its covenants related to this agreement. Remaining Payments Future remaining annual minimum principal payments for the mortgage with East West Bank as of March 31, 2026 were as follows: Year Amount 2026 $ 68,000 2027 95,000 2028 98,000 2029 112,000 2030 117,000 Thereafter 3,626,000 Total $ 4,116,000 The interest expense related to this mortgage was $ 37,000 and $ 38,000 for the three months ended March 31, 2026, and 2025, respectively. As of March 31, 2026, the interest rate for this mortgage was 3.6 %. 12. Deferred Contract Incentive Effective August 1, 2021, MSCO entered into an amendment to its clearing agreement with NFS that, among other things, extended the term of the arrangement for an additional four-year period ending July 31, 2025. Under this amendment, the Company received a one-time business development credit of $ 3.0 million and four annual credits of $ 100,000 . These amounts were recorded in the line item “Deferred contract incentive” on the statements of financial condition and were recognized as contra expense within “Clearing fees, including execution costs” on the statements of operations - the business development credit over four years and the annual credits over one year . The 2021 amendment term was completed as of July 31, 2025 and there were no early termination fees recognized during the period of this arrangement. - 15 - Effective September 29, 2025, MSCO entered into a subsequent amendment to its clearing agreement with NFS, extending the term of the arrangement for an additional five-year period, commencing September 26, 2025 and ending October 1, 2030. In connection with this amendment, the Company received a one-time business development credit of $ 4.8 million, which is recorded in “Deferred contract incentive” on the statements of financial condition and will be recognized as a contra expense over the five-year contract term within “Clearing fees, including execution costs.” The amendment also includes an early termination fee provision. Refer to Note 18 – Commitments, Contingencies, and Other for further information. In relation to these agreements, the Company recognized $ 240,000 and $ 213,000 in contra expense for the three months ended March 31, 2026, and 2025, respectively. As of March 31, 2026 and December 31, 2025, the balance of the deferred contract incentive was approximately $ 4.3 million and $ 4.6 million, respectively. 13. Revenue Recognition Refer to Note 2 – Summary of Significant Accounting Policies in Company’s 2025 Form 10-K for detail on the Company’s primary sources of revenue and the corresponding accounting treatment. There were no significant changes to the Company’s accounting policies for the three months ended March 31, 2026 for revenue recognition. Disaggregation of Revenue The Company generated a significant portion of its revenue from financial instruments comprising of margin revenue, securities lending, principal transactions and proprietary trading, and interest revenue. These net interest and other revenues are not within the scope of Topic 606, because they are generated from financial instruments covered by various other areas of GAAP. Market making activities are not within the scope of Topic 606, as they do not meet the definition of a contract with a customer under the standard. Consequently, revenue and expenses related to market making activity are accounted for separately and not included in the revenue figures presented in accordance with Topic 606. The Company also has fee revenue and transaction revenue which are within the scope of Topic 606, Revenue from Contracts with Customers. Topic 606 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance requires an entity to follow a five-step model to (a) identify the contract(s) with a customer, (b) identify the performance obligations in the contract, (c) determine the transaction price, (d) allocate the transaction price to the performance obligations in the contract, and (e) recognize revenue when (or as) the entity satisfies a performance obligation. In determining the transaction price, an entity may include variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized would not occur when the uncertainty associated with the variable consideration is resolved. - 16 - The table below presents detailed information on the Company’s recognition of revenue from contracts with customers as well as revenues from financial instruments, which are outside the scope of Topic 606, by major types of services for the periods indicated. Three Months Ended March 31, 2026 2025 Revenues from Contracts with Customers Principal transactions and proprietary trading Riskless principal transactions with customers $ 4,236,000 $ 3,740,000 Commissions and fees Brokerage commissions 1,798,000 1,543,000 Distribution fees 392,000 357,000 Insurance commissions 135,000 202,000 Interest, marketing and distribution fees Marketing and distribution fees 639,000 500,000 Stock borrow / stock loan Retail fees (rebates) 9,000 6,000 Stock locate services 4,859,000 4,032,000 Advisory fees 1,010,000 748,000 Other income Administrative fees 387,000 431,000 Payment for order flow 654,000 343,000 Music and artist services revenue 248,000 — NIL revenue 95,000 — Investment Banking Underwriting fees 1,348,000 — Financial advisory fees 225,000 — Total Revenues from contracts with customers $ 16,035,000 $ 11,902,000 Revenue Outside the Scope of Topic 606 Principal transactions and proprietary trading Proprietary trading ( 308,000 ) ( 12,000 ) Proprietary trading - equity investment — 9,233,000 Interest, marketing and distribution fees Margin interest 2,833,000 3,395,000 Interest income 2,402,000 3,050,000 Stock borrow / stock loan Stock rebate revenue 1,963,000 799,000 Market making 545,000 552,000 Total Revenue outside the scope of Topic 606 7,435,000 17,017,000 Total Revenue $ 23,470,000 $ 28,919,000 - 17 - 14. Income Taxes The Company’s provision for income taxes consists of federal and state taxes, as applicable, in amounts necessary to align the Company’s year-to-date tax provision with the effective rate that it expects to achieve for the full year. Each quarter the Company updates its estimate of the annual effective tax rate and records cumulative adjustments as necessary. As of March 31, 2026, the Company has concluded that its deferred tax assets are realizable on a more-likely-than-not basis with the exception of investments that are expected to generate capital losses when realized. For the three months ended March 31, 2026, the Company recorded an income tax benefit of $ 895,000 on pre-tax book loss of $ 2,867,000 . The effective tax rate for the three months ended March 31, 2026 was 31 %. The effective tax rate differs from the federal statutory rate of 21 % primarily related to certain permanent tax differences and state and local taxes. For the three months ended March 31, 2025, the Company recorded an income tax provision of $ 1,835,000 on pre-tax book income of $ 10,496,000 . The effective tax rate for the three months ended March 31, 2025 was 17 %. The effective tax rate differs from the federal statutory rate of 21 % primarily related to the Company’s ability to utilize certain deferred tax assets for capital loss carryforwards to offset expected capital gains on its Investment in Equity Security. These capital loss carryforwards were not previously realizable on a more-likely-than-not basis and the Company has reversed a portion of its valuation allowance resulting in an income tax benefit. As of both March 31, 2026 and December 31, 2025, the Company recorded an uncertain tax position of $ 63,000 related to various tax matters, which is included in the line item “Taxes receivable” in the statements of financial condition. 15.

Financial Instruments with Off-Balance Sheet Risk The Company enters into various transactions to meet the needs of customers, conduct trading activities, and manage market risks and is, therefore, subject to varying degrees of market and credit risk. Refer to the below as well as Note 18 – Financial Instruments with Off-Balance Sheet Risk in the Company’s 2025 Form 10-K for further information. - 19 - As of March 31, 2026, the Company had margin loans extended to its customers of approximately $ 392.0 million, of which $ 77.9 million is within the line item “Receivables from customers” on the statements of financial condition.

Earnings Per Common Share The following table sets forth the computation of basic and diluted earnings per common share for the three months ended March 31, 2026 and 2025. Three Months Ended March 31, 2026 2025 Net income (loss) $ ( 1,972,000 ) $ 8,661,000 Less net income (loss) attributable to noncontrolling interests — ( 3,000 ) Net income (loss) available to common stockholders $ ( 1,972,000 ) $ 8,664,000 Weighted-average common shares outstanding - basic 40,802,936 40,192,036 Dilutive effect of unvested shares 139,950 42,988 Weighted-average common shares used to compute diluted loss per share 40,942,886 40,235,024 Net income (loss) per share attributable to common stockholders: Basic $ ( 0.05 ) $ 0.22 Diluted $ ( 0.05 ) $ 0.22 Basic earnings per common share is calculated by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is calculated by adjusting the weighted-average number of common shares outstanding for the potential dilutive effect of securities, if applicable. For the three months ended March 31, 2026 and 2025, the Company had 805,000 and 300,000 antidilutive shares outstanding, respectively. These restricted stock units were excluded from the computation of diluted net income per share because the effect would be anti-dilutive. 18. Commitments, Contingencies, and Other Legal and Regulatory Matters In the normal course of business, the Company may be subject to various proceedings and claims arising from its business activities, including lawsuits, arbitration claims and regulatory matters. The Company is also involved in other reviews, investigations and proceedings by governmental and self-regulatory organizations regarding the business, which may result in adverse judgments, settlements, fines, penalties, injunctions and other relief. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages. In the Company’s opinion, based on currently available information, the ultimate resolution of current matters will not have a material adverse impact on the Company’s financial position and results of operations as of March 31, 2026. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. - 21 - Overnight Financing As of both March 31, 2026 and December 31, 2025, MSCO had an available line of credit for short term overnight demand borrowing with BMO Harris Bank (“BMO Harris”) of up to $ 25 million. As of those dates, MSCO had no outstanding loan balance and there were no commitment fees or other restrictions on the line of credit. The Company utilizes customer or firm securities as a pledge for short-term borrowing needs. The interest expense for this credit line was $ 0 and $ 1,000 for the three months ended March 31, 2026 and 2025, respectively. There was a commitment fee of $ 3,000 and $ 2,000 associated with the utilization of this credit line for the three months ended March 31, 2026 and 2025, respectively.

The origination fee is equal to one half of one percent ( 0.50 %) of the $ 20,000,000 revolver cap. The EWB Credit Agreement contains customary affirmative covenants and negative covenants and requires the Company to maintain a minimum debt service coverage ratio of not less than 1.35:1.00 and minimum net capital of $ 43,000,000 . Shelf Registration Statement and At the Market Offering The Company’s shelf registration statement on Form S-3 and related Sales Agreement were previously disclosed in the 2025 Form 10-K. No shares were sold under the Sales Agreement during the three months ended March 31, 2026. As of the filing date of this Report, because the Company’s public float is below $75.0 million, future primary offerings on Form S-3 are subject to the limitations of General Instruction I.B.6 of Form S-3 known as the “baby shelf rules”. - 22 - NFS Contract Effective September 29, 2025, MSCO entered into an amendment to its clearing agreement with NFS that, among other things, extends the term of the arrangement for an additional five-year period commencing on September 26, 2025 and ending October 1, 2030. If the Company chooses to exit this agreement before the end of the contract term, the Company is under the obligation to pay an early termination fee upon occurrence pursuant to the table below: Date of Termination Early Termination Fee Prior to October 2, 2026 $ 10,000,000 Prior to October 2, 2027 $ 8,000,000 Prior to October 2, 2028 $ 6,000,000 Prior to October 2, 2029 $ 5,000,000 Prior to October 2, 2030 $ 4,000,000 For the three months ended March 31, 2026 and 2025, there has been no expense recognized for any early termination fees. The Company believes that it is unlikely it will have to make material payments related to early termination fees and has not recorded any contingent liability in the financial statements related to this arrangement. Media Partnership On March 4, 2026, the Company entered into a media partnership agreement with a multimedia news platform operator for sponsored programming, branded financial content, and promotional integrations over a term of approximately 50 weeks, commencing March 16, 2026. The total contract value is $ 1.0 million, payable in a combination of cash and shares of the Company’s common stock, with a portion payable in advance. The agreement is non-cancellable.

In addition, the Company recorded approximately $ 200,000 of prepaid advertising for amounts paid in advance, which is included in “Prepaid expenses and other assets” in the statements of financial condition. General Contingencies The Company’s general contingencies are included in Note 20 – Commitments, Contingencies, and Other in the Company’s 2025 Form 10-K. Other than the below, there have been no material updates to the Company’s general contingencies during the three months ended March 31, 2026. The Company is self-insured with respect to employee health claims. As part of this plan, the Company recognized expenses of $ 416,000 and $ 385,000 for the three months ended March 31, 2026 and 2025, respectively. The Company had an accrual of $ 94,000 and $ 71,000 as of March 31, 2026 and December 31, 2025, respectively, which represents the estimate of future expense to be recognized for claims incurred during the periods. The Company believes that its present insurance coverage and reserves are sufficient to cover currently estimated exposures, but there can be no assurance that the Company will not incur liabilities in excess of recorded reserves or in excess of its insurance limits. 19. Segment Reporting The Company operates two reportable segments, Financial Services, and Media, Sports and Entertainment. The Financial Services segment includes the Company’s broker-dealer and related financial services operations. The Media, Sports and Entertainment segment includes the Company’s entertainment and sports management and related marketing, advertising, and production activities. The Chief Operating Decision Maker (“CODM”) is the Company’s Chief Executive Officer and evaluates segment performance and allocates resources using operating income, which represents the Company’s measure of segment profit or loss (the “Segment Measure”). The CODM also considers excess net capital as an operational metric in maintaining capital adequacy.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion provides a narrative of our financial performance and condition that should be read in conjunction with the accompanying financial statements and related notes included under Part I, Item 1 of this Report. In addition to our historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in our 2025 Form 10-K, particularly in Part I, Item 1A – Risk Factors. Overview We are primarily a financial services company and provide a wide variety of financial services to our clients. We operate in business lines such as retail brokerage, investment advisory, insurance, and technology development through our wholly-owned subsidiaries. We also operate a media, sports and entertainment business, although financial services remains our primary business. Results in the businesses in which we operate are highly correlated to general economic conditions and, more specifically, for our financial services businesses, to the direction of the U.S. equity and fixed-income markets. Market volatility, overall market conditions, interest rates, economic, political, and regulatory trends, industry competition, and, with respect to our media, sports and entertainment business, consumer demand for music and entertainment content, are among the factors which could affect us and which are unpredictable and beyond our control. These factors affect the financial decisions made by market participants who include investors and competitors, impacting their level of participation in the financial markets. In addition, in periods of reduced financial market activity, or lower revenue generation from our developing business lines, profitability is likely to be adversely affected because certain expenses remain relatively fixed, including salaries and related costs, as well as portions of communications costs and occupancy expenses. Accordingly, earnings for any period should not be considered representative of earnings to be expected for any other period. Financial Overview In the three months ended March 31, 2026, loss per share was $0.05, compared to earnings per share of $0.22 in the prior-year period. In the first quarter of 2026, our revenues were $23.5 million and operating loss before taxes was $2.9 million, compared to revenues of $28.9 million and operating income of $10.5 million in the prior-year period. For the three months ended March 31, 2026, our results compared to the prior-year period reflected continued growth in certain business lines, including stock borrow / stock loan and investment banking, offset by lower interest-related revenue, higher operating expenses, impairment of goodwill and an intangible asset related to our Media, Sports, and Entertainment segment, and the $9.2 million unrealized gain recognized during the prior-year period related to our Investment in Equity Security. During the three months ended March 31, 2026, we continued to invest in the expansion of our business lines and supporting infrastructure, which contributed to higher personnel expenses, commission and payout expenses, technology costs, advertising and promotion expense, and costs associated with the growth of expenses associated with music production, artist development, marketing, distribution, and related operations. These increases were partially offset by higher revenues from stock borrow / stock loan activities and investment banking fees, and the impairment expenses detailed in the sections below. The year-over-year comparison was significantly impacted by the $9.2 million unrealized gain recognized during the three months ended March 31, 2025. See “Investment in Equity Security,” “Segments,” and “Statements of Operations and Financial Condition” below for further discussion of the significant factors affecting our results. Investment in Equity Security In the first quarter of 2025, we participated in a private placement and acquired restricted shares of a privately held U.S. company (the “Investment in Equity Security”). These shares were subject to restrictions on transferability and did not have a readily determinable fair value at the time of acquisition. On March 31, 2025, the issuer completed its initial public offering “(IPO”), and our restricted shares converted into restricted publicly traded shares as part of the IPO process. These shares remained subject to resale restrictions and could not be sold unless a registration statement was filed with SEC or an applicable exemption from registration became available. Additional details are provided in the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2025. There was significant volatility in the price of the shares, and in the three months ended March 31, 2025, we recorded an unrealized gain of approximately $9.2 million as the price per share closed at $85.31 on March 31, 2025. After the lifting of contractual sale restrictions, we sold the majority of our Investment in Equity Security for an average price of $19.00 per share. We recognized a net gain of $2.4 million related to this investment following the sale of our position. - 28 - Green Pier Clearing Agreement RISE executed a fully disclosed clearing agreement with Green Pier, an indirect wholly-owned subsidiary of FMR, effective February 27, 2026. We believe the relationship will provide access to advanced clearing infrastructure and technology solutions that enhance operational capabilities, scalability, and system reliability, supporting the development and execution of RISE’s broker-dealer activities. Refer to Note 1 - Organization and Basis of Presentation for further information . Arqitech Investment In the first quarter of 2026, we made a strategic investment in Arqitech. Arqitech is an institutional-grade, non-custodial digital asset infrastructure platform that provides on-chain settlement, cross-chain execution, and decentralized financial technology solutions for regulated financial institution to support its broader technology and digital asset initiatives. We believe this investment provides exposure to institutional-grade digital asset infrastructure and anticipates it will support future growth and strategic opportunities. Media Partnership On March 4, 2026, we entered into an agreement with a multimedia news platform operator for $1 million for a media partnership designed to support marketing and promotional initiatives related to our products and services. Segments We manage our business through the following reportable segments: ● Financial Services ● Media, Sports, and Entertainment Segment results are evaluated based on operating income, which reflect the manner in which management assesses performance and allocates resources. Financial Services Three Months Ended March 31, 2026 2025 Commissions and fees $ 2,325,000 $ 2,102,000 Interest, marketing and distribution fees 5,874,000 6,945,000 Principal transactions and proprietary trading 3,928,000 12,961,000 Investment banking 1,573,000 — Market making 545,000 552,000 Stock borrow / stock loan 6,831,000 4,837,000 Advisory fees 1,010,000 748,000 Other income 1,041,000 774,000 Total Revenue 23,127,000 28,919,000 Significant segment expenses: Employee compensation and benefits 15,643,000 11,922,000 Clearing fees, including execution costs 597,000 454,000 Technology and communications 1,799,000 1,105,000 Other general and administrative 1,395,000 1,499,000 Data processing 1,286,000 949,000 Rent and occupancy 417,000 451,000 Professional fees 1,617,000 1,344,000 Depreciation and amortization 677,000 415,000 Interest expense 218,000 89,000 Advertising and promotion 580,000 154,000 Total Expenses 24,229,000 18,382,000 Operating income (loss) $ (1,102,000 ) $ 10,537,000 - 29 - Results in the Financial Services segment were impacted by continued growth in certain business lines, including stock borrow / stock loan and investment banking, which were more than offset by lower interest-related revenue and higher operating expenses. The results were significantly impacted by a $9.2 million unrealized gain recognized during the three months ended March 31, 2025 related to our investment in an equity security. This gain significantly affected year-over-year comparability, and is detailed further in the section above titled “Investment in Equity Security.” Other than the above, the primary factors impacting results in the Financial Services segment included the following: ● Higher stock borrow / stock loan revenues, driven by higher activity levels in that business line. ● Higher investment banking revenues, primarily due to increased investment banking fee activity. ● Lower interest-related revenue, primarily due to a decline in interest rates compared to the prior-year period. ● Higher commission and payout expenses, primarily associated with increased investment banking and stock borrow / stock loan revenue. ● Higher personnel expenses, driven by the continued expansion of our business lines. ● Higher technology costs, reflecting continued investment in platforms, infrastructure, and technology initiatives. ● Higher advertising and promotion expense, reflecting increased marketing, brand, and business development spend. Media, Sports and Entertainment Three Months Ended March 31, 2026 2025 Music and artist services revenue $ 248,000 $ — NIL revenue 95,000 — Total Revenue 343,000 — Significant segment expenses: Employee compensation and benefits 529,000 — Technology and communications 6,000 — Other general and administrative 160,000 10,000 Rent and occupancy 37,000 16,000 Professional fees 81,000 15,000 Depreciation and amortization 13,000 — Goodwill impairment 330,000 — Intangible asset impairment 454,000 — Advertising and promotion 320,000 — Music production, manufacturing and distribution costs 178,000 — Total Expenses 2,108,000 41,000 Operating income (loss) $ (1,765,000 ) $ (41,000 ) Results in the Media, Sports and Entertainment segment were impacted by continued investment in the growth of the Company’s music production, marketing, distribution, artist development, and related operations. The segment did not contribute positively to operating results during the three months ended March 31, 2026 or March 31, 2025, which management believes is consistent with the development stage of the business. The primary factors impacting results in the Media, Sports and Entertainment segment included the following: ● Personnel and related employee costs associated with building the segment’s operating capabilities and the growth of the business. ● Continued expenses associated with the growth of music production and operations ● NIL-related revenue and associated commission payout expenses, which represented a smaller component of segment activity during the period. ● Increased investment in artist development, including enhanced content production, marketing initiatives, and promotional activities to support emerging talent. ● Continued investment in catalogue and brand development, as management seeks to build a foundation for future recorded music, streaming, licensing, servicing, and other revenue opportunities. ● Impairment charges, including goodwill impairment related to the Media, Sports and Entertainment reporting unit and intangible asset impairment related to a specific artist contract intangible asset. - 30 - A portion of the segment’s costs are fixed or semi-fixed in nature, including personnel, administrative support, and certain infrastructure costs associated with building the segment’s operating platform. Other costs, including distribution and manufacturing-related expenses, artist development, content production, marketing, promotion, and commission payout expenses associated with NIL-related revenues, may vary based on the number of artists, releases, campaigns, NIL arrangements, and related business development activities during a given period. As a result, expenses may be incurred in advance of, or at a higher rate than, revenue recognized from recorded music sales, streaming, licensing, servicing, NIL-related activities, and other related operations. Management believes these expenditures are important to building the segment’s catalogue, brand, artist relationships, and operating infrastructure. While there can be no assurance regarding the timing or magnitude of future revenues or profitability, management expects that continued development of the segment’s catalogue, artist pipeline, and related revenue opportunities may contribute positively to operating results over time as our catalogue develops and athlete pipeline expands. The Media, Sports and Entertainment segment remains in an early-stage development phase and continued to incur costs related to artist development, content production, marketing, personnel, and infrastructure. During the three months ended March 31, 2026, management updated its forecast for the segment based on current operating performance, the status of artist/talent contracts, and expected revenue-generating opportunities. The updated forecast reflected higher costs and a slower path to profitability than previously anticipated. As a result, we recorded a non-cash goodwill impairment charge of approximately $330,000 related to the Media, Sports and Entertainment reporting unit. The impairment analysis included significant assumptions related to revenue growth, timing of artist/talent contract activity, artist-development and production costs, marketing spend, personnel and infrastructure costs, expected timing of profitability, and the discount rate. During the three months ended March 31, 2026, we recorded a noncash intangible asset impairment charge of $454,000 related to a GM artist contract intangible asset within our Media, Sports and Entertainment segment. The impairment was primarily driven by changes in the expected economics of the related artist contract and lower-than-expected performance of related artist revenue opportunities, which reduced expected future cash flows. Trends and Key Factors Affecting our Operations Market Risk Market risk is our risk of loss resulting from the impact of changes in market prices on our trading inventory and investment positions. We have exposure to market risk primarily through our broker-dealer trading operations. Through our broker-dealer subsidiary, we trade debt obligations and equity securities and maintain trading inventories to ensure availability of securities to facilitate client transactions. Inventory levels may fluctuate daily as a result of client demand. Our primary market risks relate to interest rates and equity prices. Equity risk results from changes in prices of equity securities, affecting the value of the equity securities and other instruments that derive their value from a particular stock. We may enter into underwriting commitments and, as a result, we may be subject to market risk on any unsold securities issued in the offerings to which we are committed. Risk exposure is controlled by limiting our participation, the transaction size, or through the syndication process. Interest Rates We are exposed to market risk from changes in interest rates. Such changes in interest rates primarily impact revenue from interest, marketing, and distribution fees. We primarily earn interest, marketing and distribution fees from margin interest charged on clients’ margin balances, interest on cash and securities segregated for regulatory purposes, and distribution fees from money market mutual funds in clients’ accounts. Securities segregated for regulatory purposes consist solely of U.S. government securities. If prices of U.S. government securities within our portfolio decline, we anticipate the impact to be temporary as we intend to hold these securities to maturity. We seek to mitigate this risk by managing the average maturities of our U.S. government securities portfolio and setting risk parameters for securities owned, at fair value. The following table presents simulated changes to net interest revenue over the next 12 months beginning as of March 31, 2026 and December 31, 2025, of a gradual increase or decrease in market interest rates relative to prevailing market rates at the end of each reporting period: As of March 31, 2026 December 31, 2025 Increase of 200 basis points 39 % 34 % Increase of 100 basis points 20 % 18 % Increase of 50 basis points 11 % 9 % Decrease of 50 basis points (7 )% (7 )% Decrease of 100 basis points (16 )% (15 )% Decrease of 200 basis points (34 )% (31 )% The difference in our simulated incremental increases and decreases in the market interest rates as of March 31, 2026 compared to December 31, 2025 is primarily due to differences in the proportion of segregated cash to segregated securities and differences in the proportion of margin debit balances to cash credit balances. - 31 - Technology Initiatives We have made investments in technology development projects collectively termed as Siebert’s Retail Platform. Technology development projects such as the online platform for Siebert’s retail customer base and corporate service clients have been placed into service during 2025 and several projects are anticipated to go live in 2026. In 2025, we made a minority equity investment in and entered into a strategic partnership with FusionIQ, a provider of engagement solutions and data analytics for wealth management firms, to help with these technology initiatives and new product offerings. We believe these ongoing investments in technology and partnerships will be important in meeting the needs of our retail, correspondent clearing, and corporate services customers and supporting our expansion into new markets and demographics. In February 2026, RISE entered into a clearing agreement with Green Pier, an indirect wholly owned subsidiary of FMR. The agreement was executed to support RISE’s strategic objectives through collaboration with Green Pier’s clearing infrastructure and technology platform. We believe the relationship enhances RISE’s operational capabilities and scalability and supports the execution of its broker-dealer activities.

Principal transactions and proprietary trading for the three months ended March 31, 2026 was $3,928,000 and decreased by $9,033,000 from the corresponding period in the prior year, primarily due to the unrealized gain related to the Investment in Equity Security in the first quarter of 2025.

Technology and communications expenses for the three months ended March 31, 2026 were $1,805,000 and increased by $700,000 from the corresponding period in the prior year, primarily due to an expansion of technological infrastructure. Other general and administrative expenses for the three months ended March 31, 2026 were $1,733,000 and increased by $224,000 from the corresponding period in the prior year primarily due to expansion of business lines. Data processing expenses for the three months ended March 31, 2026 were $1,286,000 and increased by $337,000 from the corresponding period in the prior year, primarily due to expansion of technology infrastructure.

Refer to Note 9 – Goodwill and Other Intangible Assets, Net for further information. Intangible asset impairment for the three months ended March 31, 2026 was $454,000 and increased by $454,000 from the corresponding period in the prior year, due to the intangible asset impairment related to the artists contracts in the Media, Sports, and Entertainment segment. Refer to Note 9 – Goodwill and Other Intangible Assets, Net for further information. Interest expense for the three months ended March 31, 2026 was $218,000 and increased by $129,000 from the corresponding period in the prior year, primarily due to interest related to short term line of credit with East West bank. Advertising and promotion expense for the three months ended March 31, 2026 was $900,000 and increased by $746,000 from the corresponding period in the prior year, primarily due to an increase in marketing initiatives. Provision For (Benefit From) Income Taxes The benefit from income taxes for the three months ended March 31, 2026 was $895,000 and decreased by $2,730,000 from the corresponding period in the prior year, primarily due to a pre-tax loss in the three months ended March 31, 2026. Refer to Note 14 – Income Taxes for additional detail. Net Income (Loss) Attributable to Noncontrolling Interests The net loss attributable to noncontrolling interests for the three months ended March 31, 2026 was $0 and decreased by $3,000 from the corresponding period in the prior year, primarily due to Siebert’s noncontrolling interest in RISE for the three months ended March 31, 2025. The net loss attributable to noncontrolling interests represented the portion of RISE’s results attributable to ownership interests not held by Siebert. Siebert consolidates RISE’s financial results and reflects the portion not owned by Siebert as noncontrolling interests. As of March 31, 2026 and December 31, 2025, RISE was wholly owned by Siebert. - 33 - Statements of Financial Condition As of March 31, 2026 and December 31, 2025 Assets Assets as of March 31, 2026 were $597,142,000 and decreased by $161,900,000 from December 31, 2025, primarily due to a decrease in securities borrowed and cash and securities segregated for regulatory purposes, partially offset by an increase in receivables from broker-dealers and clearing organizations and receivables from customers. Liabilities Liabilities as of March 31, 2026 were $509,022,000 and decreased by $160,860,000 from December 31, 2025, primarily due to a decrease in securities loaned and payables to customers. Liquidity and Capital Resources Overview As of March 31, 2026, a significant portion of our assets were liquid in nature, providing us with flexibility in financing our business. A significant portion of our assets not held by customers or used for stock borrow / stock loan consisted primarily of cash and cash equivalents, securities owned, at fair value, which are marked-to-market daily, and receivables from and deposits with broker-dealers and clearing organizations. We expect to use our available cash, cash equivalents, and potential future borrowings under our debt agreements and potential issuance of new debt or equity, to support and invest in our core business, including investing in new ways to serve our customers, potentially seeking strategic acquisitions to leverage existing capabilities, and for general capital needs (including capital, deposit, and collateral requirements imposed by regulators and SROs). Based on our current level of operations, we believe our available cash, available lines of credit, overall access to capital markets, and cash provided by operations will be adequate to meet our current liquidity needs for the foreseeable future. As of the date of this Report, other than the items detailed in the cash requirements section below, there are no known or material events that would require us to use large amounts of our liquid assets to cover expenses. Cash and Cash Equivalents Our cash and cash equivalents were $16.2 million and $22.4 million as of March 31, 2026 and December 31, 2025, respectively. EWB Credit Agreement On August 15, 2024, we entered into the EWB Credit Agreement with East West Bank providing a $20 million revolving credit facility. This credit facility allows us to fund acquisitions, execute stock buybacks, and meet general corporate needs up to $10 million, ensuring access to capital for both growth and operational purposes. The maturity date of the EWB Credit Agreement is July 29, 2027. The interest rate structure that is tied to either the one-month Term SOFR plus 3.15% or a minimum of 7.50%. John J. Gebbia and Gloria E. Gebbia, and their trust, provided personal guarantees related to this agreement which further strengthen our borrowing position and help secure favorable terms. As of March 31, 2026, $5 million was outstanding related to the above EWB Credit Agreement. The interest expense for this credit line was $95,000 and $0 for the three months ended March 31, 2026 and 2025, respectively. The interest rate was 7.5% for this credit facility during the three months ended March 31, 2026. BMO Credit Agreement On November 22, 2024, MSCO entered into the BMO Credit Agreement with BMO Harris. The BMO Credit Agreement provides for a revolving credit facility of up to $20,000,000. We may use any borrowings under the BMO Credit Agreement to finance NSCC Deposit Requirements (other than an Adequate Assurance Deposit) and withdrawals from a Reserve Account. As part of the agreement, we entered into a Parent Guaranty agreement guaranteeing repayment of any debt issued to MSCO. - 34 - Effective November 22, 2025, MSCO renewed the BMO Credit Agreement with BMO Harris until November 20, 2026. Borrowings under the BMO Credit Agreement will bear interest on the outstanding daily balance at a rate of interest per annum equal 2.5% plus the greater of: (a) Term SOFR for such day plus 0.11448% and (b) Federal Funds Target Range – Upper Limit and (c) 0.25%. The annual commitment fee is equal to one half of one percent (0.50%) of the average daily unused portion of the commitment of $20,000,000. The BMO Credit Agreement contains customary affirmative covenants and negative covenants and requires MSCO to maintain minimum total regulatory capital of $45,000,000, excess net capital of 20,000,000, assets to total regulatory capital ratio of not more than 5.0 to 1.0, and a minimum liquidity ratio of not less than 1.0. Debt Agreements We have $4.1 million outstanding on our mortgage with East West Bank and an unutilized line of credit for short term overnight demand borrowing of up to $25 million with BMO Harris as of March 31, 2026. As of March 31, 2026, we were in compliance with all covenants related to our mortgage agreement. Cash Requirements The following table summarizes our short- and long-term material cash requirements as of March 31, 2026. Payments Due By Period 2026 2027 2028 2029 2030 Thereafter Total Operating lease commitments $ 875,000 $ 919,000 $ 632,000 $ 13,000 $ — $ — $ 2,439,000 Kakaopay fee (1) 500,000 — — — — — 500,000 Mortgage with East West Bank (2) 68,000 95,000 98,000 112,000 117,000 3,626,000 4,116,000 Broadridge contract (3) 413,000 550,000 504,000 — — — 1,467,000 Media agreement (4) 800,000 — — — — — 800,000 Total $ 2,656,000 $ 1,564,000 $ 1,234,000 $ 125,000 $ 117,000 $ 3,626,000 $ 9,322,000 (1) Pursuant to the Settlement Agreement with Kakaopay, we will pay Kakaopay a fee of $5 million payable in ten quarterly installments that began in the first quarter of 2024. Refer to Note 6 – Kakaopay Transaction in our 2025 Form 10-K for further detail. (2) On December 30, 2021, we purchased the Miami office building and financed part of the purchase price with a mortgage with East West Bank. (3) In November 2025, we entered into an amendment to its service agreement with Broadridge Securities Processing Solutions, LLC with a total minimum expense of approximately $1.7 million for this arrangement. (4) In March 2026, we entered into a media partnership agreement with a multimedia news platform operator with a total cost of $1.0 million, comprised of $800,000 in cash and $200,000 in stock. Refer to Note 18 – Commitments, Contingencies, and Other for further detail. Net Capital, Reserve Accounts, Segregation of Funds, and Other Regulatory Requirements MSCO is subject to the Uniform Net Capital Rules of the SEC (Rule 15c3-1) and the Customer Protection Rule (15c3-3) of the Exchange Act and maintains capital and segregated cash reserves in excess of regulatory requirements. Requirements under these regulations may vary; however, MSCO has adequate reserves and contingency funding plans in place to sufficiently meet any regulatory requirements. In addition to net capital requirements, as a self-clearing broker-dealer, MSCO is subject to cash deposit and collateral requirements with clearing houses, such as the DTCC and OCC, which may fluctuate significantly from time to time based upon the nature and size of clients’ trading activity and market volatility. RISE, as a member of FINRA, is subject to the SEC Uniform Net Capital Rule 15c3-1 and the corresponding regulatory capital requirements. MSCO can transfer funds to Siebert as long as MSCO maintains its liquidity and regulatory capital requirements. RISE can transfer funds to its shareholders, of which Siebert is entitled to its proportional ownership interest, as long as RISE maintains its liquidity and regulatory capital requirements. For the three months ended March 31, 2026 and 2025, MSCO and RISE had sufficient net capital to meet their respective liquidity and regulatory capital requirements. Refer to Note 15 – Capital Requirements for more detail about our capital requirements. - 35 - Cash Flows Cash used in operating activities consisted of net income adjusted for certain non-cash items. Net operating assets and liabilities at any specific point in time are subject to many variables, including variability in customer activity, the timing of cash receipts and payments, and vendor payment terms. The total changes in our statements of cash flows, especially our operating cash flow, are not necessarily indicative of the ongoing results of our business as we have customer assets and liabilities on our statements of financial condition. For the three months ended March 31, 2026, cash used in operating activities decreased by $8.4 million compared to the prior year period, which was primarily driven by the net change in securities loaned, securities borrowed, securities segregated, and receivables from broker-dealers and clearing organizations. For the three months ended March 31, 2026, cash used in investing activities decreased by $0.2 million compared to the prior year period, which was primarily driven by less investment in capitalized software development cost, partially offset by the investment in Arqitech. For the three months ended March 31, 2026, cash flows used in financing activities decreased by $35,000 compared to the prior year period, which was primarily due to a RISE cash distribution in the first quarter of 2025. Long Term Contracts Effective September 29, 2025, MSCO entered into an amendment to its clearing agreement with NFS that, among other things, extends the term of their arrangement for an additional five-year period commencing on September 26, 2025 and ending October 1, 2030. As part of this agreement, we received a one-time business development credit of $4.8 million. The amendment also provides for an early termination fee; however, as of March 31, 2026, we do not expect to terminate the contract with NFS before the end of the contract term. For the three months ended March 31, 2026 and 2025, there was no expense recognized for any early termination fees. Refer to Note 12 – Deferred Contract Incentive and Note 18 – Commitments, Contingencies and Other for additional detail. Effective November 2025, MSCO entered into an amendment to its service agreement with Broadridge Securities Processing Solutions, LLC that, among other things, extends the term of their arrangement for a three-year period ending November 2028, with an option to terminate after three years. As of March 31, 2026, the total remaining minimum expense for this arrangement is estimated at approximately $1.5 million over the duration of the contract. Off-Balance Sheet Arrangements We enter into various transactions to meet the needs of customers, conduct trading activities, and manage market risks and are, therefore, subject to varying degrees of market and credit risk. In the normal course of business, our customer activities involve the execution, settlement, and financing of various customer securities transactions. These activities may expose us to off-balance sheet risk in the event the customer or other broker is unable to fulfill their contracted obligations and we are forced to purchase or sell the financial instrument underlying the contract at a loss. There were no material losses for unsettled customer transactions for the three months ended March 31, 2026 and 2025. Refer to Note 16 – Financial Instruments with Off-Balance Sheet Risk for additional detail. Uncertain Tax Positions We account for uncertain tax positions in accordance with the authoritative guidance issued under ASC 740-10, which addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. We may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. ASC 740-10 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure requirements. We recognize interest and penalties related to unrecognized tax benefits on the provision for income taxes line on the statements of operations. Accrued interest and penalties would be included on the related tax liability line on the statements of financial condition. As of both March 31, 2026 and December 31, 2025, the Company recorded an uncertain tax position of $63,000 related to various tax matters, which is included in the line item “Taxes receivable” in the statements of financial condition. - 36 - Critical Accounting Policies and Estimates Certain of our accounting policies that involve a higher degree of judgment and complexity are discussed in Part I, Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2025 Form 10-K. As of March 31, 2026, there have been no changes to our critical accounting policies or estimates other than the below. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment at least annually, or more frequently when events or circumstances indicate that the fair value of a reporting unit may be below its carrying amount. We test goodwill at the reporting unit level by comparing the estimated fair value of the reporting unit to its carrying amount. If the carrying amount exceeds the estimated fair value, an impairment charge is recorded, limited to the amount of goodwill allocated to that reporting unit. Estimating fair value requires significant judgment and may include the use of discounted cash flow analyses, market-based approaches, or a combination of valuation methods, depending on the facts and circumstances. Significant assumptions and judgments may include projected revenue, operating costs, future cash flows, timing of profitability, terminal growth rates, discount rates, selected comparable company multiples, and the selection and weighting of valuation methodologies. During the three months ended March 31, 2026, we recorded a noncash goodwill impairment charge of approximately $330,000 related to the Media, Sports and Entertainment reporting unit. The impairment analysis required management to make significant estimates and assumptions, including projected revenue growth, artist contract activity, expected profitability, terminal growth rate, and discount rate. Following the impairment, no goodwill remained assigned to the Media, Sports and Entertainment reporting unit. We also evaluated our Financial Services reporting unit and concluded that no impairment existed as of March 31, 2026. New Accounting Standards In November 2024, the FASB issued ASU “2024-03”, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures” (“ASU 2024-03”). The ASU is intended to enhance the transparency and decision usefulness of income statement expense disclosures by requiring greater disaggregation of certain expense categories. In January 2025, the FASB issued ASU 2025-01, which clarified the effective date of ASU 2024-03. For public business entities, the amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. We are currently evaluating the impact that ASU 2024-03 will have on our consolidated financial statements and we anticipate the amendments will require significant changes to our expense disclosures. In September 2025, the FASB issued ASU No. 2025-06, “Intangibles-Goodwill and Other- Internal-Use Software” (“ASU 2025-06”). The ASU is intended to modernize and clarify the threshold for when an entity is required to start capitalizing software costs and is based on when (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 will be effective for Siebert for fiscal years beginning after December 15, 2027, and interim reporting periods, with early adoption permitted. We are evaluating the impact of the standard on our disclosures. Accounting Standards Adopted in Fiscal 2026 In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments-Credit Losses” (“ASU 2025-05”). The ASU is intended to provide an optional practical expedient when applying the guidance related to the estimation of expected credit losses for current accounts receivable and current contract assets resulting from transactions arising from contracts with customers. ASU 2025-05 will be effective for Siebert for fiscal years beginning after December 15, 2025, and interim reporting periods, with early adoption permitted. We adopted the standard in the three months ended March 31, 2026 and the adoption of ASU 2025-05 did not have a material impact on our financial statements. - 37 - ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Financial Instruments Held For Trading Purposes We do not directly engage in derivative transactions, have no interest in any special purpose entity and have no liabilities, contingent or otherwise, for the debt of another entity. Financial Instruments Held For Purposes Other Than Trading We generally invest our cash and cash equivalents temporarily in dollar denominated bank account(s). These investments are not subject to material changes in value due to interest rate movements. We invest cash and securities segregated for regulatory purposes in dollar denominated bank accounts which are not subject to material changes in value due to interest rate movements. We also invest cash and securities segregated for regulatory purposes and securities owned, at fair value in U.S. government securities which may be subject to material changes in value due to interest rate movements. Securities owned, at fair value invested in U.S. government securities are generally purchased to enhance yields on required regulatory deposits. While the value of the government securities may be subject to material changes in value, we believe any reduction in value would be temporary since the securities would mature at par value. Customer transactions are cleared through clearing brokers on a fully disclosed basis and are also self-cleared by MSCO. If customers do not fulfill their contractual obligations any loss incurred in connection with the purchase or sale of securities at prevailing market prices to satisfy customer obligations may be incurred by Siebert. We regularly monitor the activity in customer accounts for compliance with margin requirements. We are exposed to the risk of loss on unsettled customer transactions if customers and other counterparties are unable to fulfill their contractual obligations. There were no material losses for unsettled customer transactions in the last five years. See Item 2. – Management’s Discussion and Analysis of Financial Condition and Results of Operations - Trends and Key Factors Affecting our Operations of this Report for our quantitative and qualitative disclosures about market risk. ITEM 4. CONTROLS AND PROCEDURES Disclosure Controls and Procedures We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Executive Vice President / Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Report pursuant to Rule 13a-15(e) or Rule 15d-15(e) of the Exchange Act. Based on its evaluation, our management, including our Chief Executive Officer and our Executive Vice President / Chief Financial Officer, concluded that as of the end of the period covered by this quarterly report, our disclosure controls and procedures were effective. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting during the most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. - 38 - PART II - OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS In the normal course of business, we may be subject to various proceedings and claims arising from our business activities, including lawsuits, arbitration claims and regulatory matters. We are also involved in other reviews, investigations and proceedings by governmental and self-regulatory organizations regarding the business, which may result in adverse judgments, settlements, fines, penalties, injunctions and other relief. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages. In our opinion, based on currently available information, the ultimate resolution of current matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. ITEM 1A. RISK FACTORS In addition to the other information set forth in this Report, investors should carefully consider the risk factors discussed in Part I, Item 1A - Risk Factors in our 2025 Form 10-K. Each of such risk factors could materially affect our business, financial position, and results of operations. As of the date of this Report, there have been no material changes from the risk factors disclosed in our 2025 Form 10-K. ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS None. ITEM 3. DEFAULTS UPON SENIOR SECURITIES None. ITEM 4. MINE SAFETY DISCLOSURES Not applicable. ITEM 5. OTHER INFORMATION None of our directors or officers adopted , modified or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement during the three months ended March 31, 2026, as such terms are defined under Item 408(a) of Regulation S-K.
