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 2024 Form 10-K.

Reclassification

Certain amounts for the three and nine months ended September 30, 2024 and certain cash flows within the Investing Activities section have been reclassified to conform to the presentation of the current period. The reclassification has not materially impacted the Company’s financial statements, and did not result in a change in total revenue, net income or cash flows from operations or investing activities for the periods presented.

Principles of Consolidation

The financial statements include the accounts of Siebert and its wholly-owned and majority-owned consolidated subsidiaries. Upon consolidation, all intercompany balances and transactions are eliminated. The Company’s ownership in RISE was 68% as of both September 30, 2025 and December 31, 2024. Refer to Note 5 – RISE in the Company’s 2024 Form 10-K and Note 22 - Subsequent Events in this Report for further information.

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 statements of operations. The portion of total equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests in the statements of financial condition.

Significant Accounting Policies

The Company’s significant accounting policies are included in Note 2 – Summary of Significant Accounting Policies in the Company’s 2024 Form 10-K. During the three and nine months ended September 30, 2025. Except as set forth below, those policies were unchanged during the three and nine months ended September 30, 2025.

Asset Acquisitions

An asset acquisition is an acquisition of an asset, or a group of assets, that does not meet the definition of a business. Asset acquisitions are accounted for by using the cost accumulation model whereby the cost of the acquisition, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. Refer to Note 3 – Asset Acquisition for further detail.

Investment in Equity Securities

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 the Company’s 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, 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, with the remaining position sold by August 2025. The Company recognized a total realized gain of $2.4 million for the nine months ended September 30, 2025.

After the U.S. company’s IPO, the investment was classified as a Level 1 asset in the fair value hierarchy since the investment was publicly traded with quoted prices in an active market; however, the Company sold all of its initial position in the Investment in Equity Security as of September 30, 2025. Refer to Note 5 – Fair Value Measurements and Note 13 – Revenue Recognition for further information.

The Company will continue to measure its other investment at fair value in accordance with ASC 321 “Investments – Equity Securities.” Refer to Note 10 – Investments, Cost for further information.

2. New Accounting Standards

Recently Issued Accounting Standards

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures” (“ASU 2023-09”). The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 will be effective for the Company for annual periods beginning after December 15, 2024, though early adoption is permitted. The Company is still evaluating the presentational effect that ASU 2023-09 will have on its consolidated financial statements, but the Company expects considerable changes to its income tax footnote.

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. ASU 2024-03 will be effective for the Company for annual periods beginning after December 15, 2025, though early adoption is permitted. The Company is still evaluating the impact that ASU 2024-03 will have on its consolidated financial statements, but the Company expects the amendments will require significant changes to its expense disclosures.

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 is evaluating the impact of the standard on its financial statements.

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 2025

The Company did not adopt any new accounting standards during the three and nine months ended September 30, 2025. 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 September 30, 2025.

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.

The purchase price was allocated as follows:

Consideration:
Cash payment	$	337,000
Direct transaction costs		104,000
Total consideration	$	441,000

8. Leases

As of September 30, 2025, all of the Company’s leases are classified as operating and primarily consist of office space leases expiring in 2025 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.

Refer to Note 2 – Summary of Significant Accounting Policies in the Company’s 2024 Form 10-K for further information.

Other Intangible Assets, Net

As a result of the Company’s acquisition of GM, the Company acquired intangible assets consisting of GM artist contracts, the fair value of which were $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 the intangible asset totaled $48,000 and $145,000 for the three and nine months ended September 30, 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, 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 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 $22,000 for both the three and nine months ended September 30, 2025.

As of September 30, 2025, the Company estimates the following future amortization of other intangible assets:

Year	Amount
2025	$	62,000
2026		246,000

10. Investments, Cost

In the second quarter of 2025, the Company made strategic investments for a total of $2.0 million in IQvestment Holdings, LLC, (“FusionIQ”) a cloud-native digital wealth management platform for financial advisors and institutions. As of September 30, 2025, the Company maintained a 5% 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.

As of September 30, 2025, 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.

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 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 includes commission income charged to retail clients for executing transactions, markups on riskless principal transactions charged to retail clients for executing transactions, distribution income received from mutual funds for client transactions, stock locate fees charged to counterparties for providing locate services, payment for order flow received for executing transactions, administrative fees to retail clients including for maintenance and other ancillary services, advisory fee revenue from investment management services provided to clients, investment banking fees for underwriting, advisory, capital markets services, NIL revenue and revenue generated from digital streaming, licensing fees, physical music sales, and other performance-rights sources. Under Topic 606, Revenue from Contracts with Customers, 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.

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 September 30, 2025, 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 and nine months ended September 30, 2025, the Company recorded an income tax provision of $564,000 and $1,286,000 on pre-tax book income $2,188,000 and $6,852,000, respectively. The effective tax rate for the three and nine months ended September 30, 2025 was 25.8% and 18.8% respectively. 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.

For the three and nine months ended September 30, 2024, the Company recorded an income tax provision of $1,005,000 and $3,952,000 on pre-tax book income of $4,839,000 and $15,520,000. The effective tax rate for the three and nine months ended September 30, 2024 was 21% and 25% respectively. The effective tax rate differs from the federal statutory rate of 21% primarily related to certain permanent tax differences and state and local taxes including the impact of finalizing the prior year tax filings.

As of both September 30, 2025 and December 31, 2024, the Company recorded an uncertain tax position of $1,354,000 related to various tax matters, which is included in the line item “Taxes payable” in the statements of financial condition.

On July 4, 2025, President Trump signed H.R. 1, the One Big Beautiful Bill Act (“OBBBA”), into law. The OBBBA makes permanent many of the provisions previously enacted as part of the 2017 Tax Cut and Jobs Act that were set to expire at the end of 2025 and includes other changes to certain U.S. corporate tax provisions including the restoration of immediate expensing for domestic research and development expenditures and the reinstatement of 100% bonus depreciation for qualified property. FASB Topic 740, “Income Taxes”, requires the effects of tax law changes to be recognized in the period of enactment and requires that adjustments to prior year income taxes receivable (payable) or deferred taxes, including any related valuation allowance be recognized as a discrete event in the interim period that includes the enactment date. In connection with the tax law change, the Company was not required to record any incremental income tax expense or benefit in the three months ended September 30, 2025.

17. Earnings Per Common Share

The following table sets forth the computation of basic and diluted earnings per common share for the three and nine months ended September 30, 2025 and 2024.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025			2024
Net income	$	1,624,000	$	3,834,000	$	5,566,000		$	11,568,000
Less net income (loss) attributable to noncontrolling interests		2,000		8,000		(1,000	)		14,000
Net income available to common stockholders	$	1,622,000	$	3,826,000	$	5,567,000		$	11,554,000

Weighted-average common shares outstanding - basic		40,424,577		40,022,458		40,339,709			39,894,622
Dilutive effect of unvested shares		379,638		—		285,893			—
Weighted-average common shares used to compute diluted loss per share		40,804,215		40,022,458		40,625,602			39,894,622

Net income per share attributable to common stockholders:
Basic	$	0.04	$	0.10	$	0.14		$	0.29
Diluted	$	0.04	$	0.10	$	0.14		$	0.29

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 and nine months ended September 30, 2025, the Company had 0 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. The Company had no anti-dilutive shares outstanding as of December 31, 2024.

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 September 30, 2025. 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.

Overnight Financing

As of both September 30, 2025 and December 31, 2024, MSCO had an available line of credit for short term overnight demand borrowing with BMO Harris Bank (“BMO Harris”) of up to $25 million.

The interest expense for this credit line was $1,000 and $5,000 for the nine months ended September 30, 2025 and 2024, respectively. There were no fees related to this line of credit for the three or nine months ended September 30, 2025 and 2024.

BMO Credit Agreement

On November 22, 2024, MSCO entered into a Credit Agreement (the “BMO Credit Agreement”) with BMO Bank N.A. (“BMO”), a national banking association. The BMO Credit Agreement provides for a revolving credit facility of up to $20,000,000. The Company 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.

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 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.

There was no interest expense for the BMO Credit Agreement for the three and nine months ended September 30, 2025 and 2024. The fee for this credit line was $42,000 and $0 for the three months ended September 30, 2025 and 2024.

The EWB Credit Agreement provides for a revolving credit facility of up to $20,000,000. The maturity date of the EWB Credit Agreement is July 29, 2027. The Company may use any borrowings under the EWB Credit Agreement for acquisitions, stock buybacks, and for general corporate purposes in an amount not to exceed $10,000,000. Obligations under the EWB Credit Agreement are guaranteed by John J. Gebbia, the Company’s Chief Executive Officer, Gloria E. Gebbia, a Director of the Company, and John J. Gebbia and Gloria E. Gebbia, as co-trustees of the John and Gloria Living Trust. As of September 30, 2025, $1 million was outstanding related to the EWB Credit Agreement.

Borrowings under the EWB Credit Agreement bear interest on the outstanding daily balance at a rate of interest per annum equal to the greater of: (a) the one-month Term Secured Overnight Financing Rate (“Term SOFR”), as administered by CME Group Benchmark Administration plus 3.15% and (b) 7.50%. 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

On May 30, 2025, the Company filed a shelf registration statement on Form S-3 that was declared effective by the SEC on June 9, 2025 for the potential offering, issuance and sale of up to $100.0 million of our common stock, preferred stock, warrants to purchase the Company’s common stock and/or preferred stock, units consisting of all or some of these securities and subscription rights to purchase all or some of these securities. On June 27, 2025, the Company entered into a Sales Agreement (“Sales Agreement”) with its subsidiary, Muriel Siebert & Co., LLC, and Ladenburg Thalmann & Co. Inc., as agents, under which the Company may offer and sell, through or to the agents, shares of its common stock having an aggregate offering price of up to $50.0 million, from time to time. Accordingly, the Company has utilized $50 million of the $100 million capacity under the shelf registration statement.

For the three and nine months ended September 2025, the Company did not sell any shares pursuant to this Sales Agreement. For the three and nine months ended September 30, 2025, the Company incurred approximately $231,000 and $310,000, respectively, in legal and audit fees related to the shelf registration statement and Sales Agreement.

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 and nine months ended September 30, 2025 and 2024, 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.

General Contingencies

The Company’s general contingencies are included in Note 21 – Commitments, Contingencies, and Other in the Company’s 2024 Form 10-K. Other than the below, there have been no material updates to the Company’s general contingencies during the three and nine months ended September 30, 2025.

The Company is self-insured with respect to employee health claims. As part of this plan, the Company recognized expenses of $83,000 and $229,000 for the three months ended September 30, 2025 and 2024, respectively. For the nine months ended September 30, 2025 and 2024, the Company recognized expenses of $717,000 and $956,000, respectively.

The Company had an accrual of $65,000 and $76,000 as of September 30, 2025 and December 31, 2024, respectively, which represents the estimate of future expense to be recognized for claims incurred during the periods.

- 21 -

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 in a single line of business as a securities broker-dealer providing comprehensive brokerage services including custody and clearance of retail accounts, principal transaction and proprietary trading, market making, and securities lending. The Company’s Chief Operating Decision Maker (“CODM”), its Chief Financial Officer, reviews operating and financial information of the Company as a whole as presented on the statements of operations as well as the financial table in Note 13 – Revenue Recognition, and uses net income as the key measure to evaluate the results of the business, predominately in the forecasting process, to manage the Company. The CODM has determined that all activities contribute to the core brokerage business and the Company operates as a single reportable segment. The Company’s operations constitute a single operating segment and therefore, a single reportable segment, because the CODM manages the business activities using information of the Company as a whole. The accounting policies used to measure the profit and loss of the segment are the same as those described in the summary of significant accounting policies.

20. Employee Benefit Plans

The Company sponsors a defined-contribution retirement plan under Section 401(k) of the Internal Revenue Code that covers substantially all employees (“401(k) plan”). Participant contributions to the 401(k) plan are voluntary and are subject to certain limitations. The Company may also make discretionary contributions to the plan. For 401(k) employee contribution matching, the Company incurred expense of $27,000 and $13,000 for the three months ended September 30, 2025 and 2024, respectively. For the nine months ended September 30, 2025 and 2024, the Company incurred an expense of $211,000 and $176,000, respectively.

On September 17, 2021, the Company’s shareholders approved the Siebert Financial Corp. 2021 Equity Incentive Plan (the “Plan”).

ITEM 2. 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 2024 Form 10-K, particularly in Part I, Item 1A – Risk Factors.

Overview

We are 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 and majority-owned subsidiaries.

Results in the businesses in which we operate are highly correlated to general economic conditions and, more specifically, to the direction of the U.S. equity and fixed-income markets. Market volatility, overall market conditions, interest rates, economic, political, and regulatory trends, and industry competition 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, 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 third quarter of 2025, earnings per share was $0.04, compared to earnings per share of $0.10 in the third quarter of 2024. In the third quarter of 2025, our revenues were $26.8 million and operating income before taxes was $2.2 million, compared to revenues of $22.6 million and operating income before taxes of $4.8 million in the third quarter of 2024.

Financial highlights for the three months ended September 30, 2025:

	●	Principal transactions increased by 9.7% to $4.6 million compared to the prior-year quarter

	●	Stock borrow / stock loan increased by 73.7% to $10.0 million compared to the prior-year quarter

●

Other income increased by 92.1% to $1.4 million compared to the prior-year quarter

Acquisition of BMLG Assets

To expand upon our 2024 acquisition of GM, in the second quarter of 2025, we acquired certain assets from BMLG related to music masters, including associated copyrights and artwork. This acquisition gives Siebert ownership of recorded masters from artists such as Daughtry, Badflower, Sammy Hagar, Olive Vox, and Ryan Perdz, among others. The total cost of the acquisition was $441,000, which includes cash consideration of $337,000 and direct transaction costs of $104,000.

We generated recorded music revenue and incurred costs related to artist signings, music and video production, distribution costs, and marketing and promotion. As expected, these investments have not yet contributed positively to operating results. Management believes these expenditures are essential to building the label’s catalogue and brand, and anticipates that future revenues from recorded music sales, streaming, and licensing will drive profitability over time. While there is no assurance regarding the timing or magnitude of future earnings, we expect the label to contribute positively to overall operating results as its catalogue matures.

NIL Revenue

In the third quarter of 2025, we began earning revenue in a new revenue stream relating to NIL negotiation services on behalf of student-athletes with university athletic departments or NIL collectives. We earned $362,000 in revenue related to this new revenue stream in the third quarter of 2025.

- 25 -

Investment in Equity Security

In the first quarter of 2025, we acquired the Investment in Equity Security in connection with a private placement from a private U.S company that subsequently completed an IPO. Following the IPO, these shares were subject to resale restrictions until they were registered with the SEC. In June 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, with the remaining position sold by August 2025. We recognized a total realized gain of $2.4 million for the nine months ended September 30, 2025. The realized gain associated with the Investment in Equity Security is recorded in the line item “Principal transactions and proprietary trading” in our statement of operations. Refer to Note 13 – Revenue Recognition for further information.

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 September 30, 2025 and December 31, 2024, of a gradual increase or decrease in market interest rates relative to prevailing market rates at the end of each reporting period:

	As of
	September 30, 2025			December 31, 2024
Increase of 200 basis points		32	%		32	%
Increase of 100 basis points		16	%		18	%
Increase of 50 basis points		8	%		11	%
Decrease of 50 basis points		(7	)%		(4	)%
Decrease of 100 basis points		(15	)%		(11	)%
Decrease of 200 basis points		(31	)%		(26	)%

The difference in our simulated incremental increases and decreases in the market interest rates as of September 30, 2025 compared to December 31, 2024 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.

Technology Initiatives

At the end of 2023, we hired new technology personnel, changed our primary software development vendor, and 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 in the nine months ended September 30, 2025 and several projects are anticipated to go live in early 2026. We have also made an investment in FusionIQ to help with these technology initiatives and new product offerings. We believe that these ongoing investments in technology will be key in meeting the needs of our retail customers, correspondent clearing, corporate services as well as our expansion into new markets and demographics.

Liquidity and Capital Resources

Overview

As of September 30, 2025, 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.

Kakaopay

The net capital infusion from Kakaopay in 2023 was approximately $14.8 million after the issuance cost. This capital is used to enhance our regulatory capital, and is primarily invested in U.S. government securities and is in the line item “Securities owned, at fair value” on the statements of financial condition. Refer to Note 6 – Kakaopay Transaction in our 2024 Form 10-K for further detail.

Cash and Cash Equivalents

Our cash and cash equivalents were $19.6 million and $32.6 million as of September 30, 2025 and December 31, 2024, 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, which offers financial flexibility to support our strategic initiatives. 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%, provides a stable and predictable financing source. The personal guarantees provided by key executives, John J. Gebbia and Gloria E. Gebbia, and their trust, further strengthen our borrowing position and helping to secure favorable terms.

As of September 30, 2025, $1 million was outstanding related to the above Credit Agreement.

BMO Credit Agreement

On November 22, 2024, MSCO entered into a Credit Agreement (the “BMO Credit Agreement”) with BMO Harris Bank (“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.

- 30 -

Debt Agreements

We have $4.2 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 September 30, 2025. As of September 30, 2025, we were in compliance with all covenants related to our mortgage agreement.

Shelf Registration Statement

On May 30, 2025, we filed a shelf registration statement on Form S-3 that was declared effective by the SEC on June 9, 2025 for the potential offering, issuance and sale by us of up to $100.0 million of our common stock, preferred stock, warrants to purchase our common stock and/or preferred stock, units consisting of all or some of these securities and subscription rights to purchase all or some of these securities. As noted below under “At the Market Offering,” we have utilized $50 million of the $100 million capacity under the shelf registration statement for our At the Market program.

At the Market Offering

On June 27, 2025, we entered into a Sales Agreement (“Sales Agreement”) with our subsidiary, Muriel Siebert & Co., LLC, and Ladenburg Thalmann & Co. Inc., as agents, under which we may offer and sell, through or to the agents, shares of our common stock having an aggregate offering price of up to $50.0 million, from time to time. For the three and nine months ended September 30, 2025, we did not sell any shares pursuant to this Sales Agreement. Refer to Note 18 – Commitments, Contingencies and Other for additional 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 and nine months ended September 30, 2025 and 2024, 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.

- 31 -

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 nine months ended September 30, 2025, cash provided by operating activities increased by $35.2 million compared to the prior year period, which was primarily driven by the net change in securities loaned, securities borrowed and payables to customers.

For the nine months ended September 30, 2025, cash used in investing activities increased by $0.3 million compared to the prior year period, which was primarily driven by the investment in FusionIQ, partially offset by less investment in office facilities and software.

For the nine months ended September 30, 2025, cash flows provided by financing activities increased by $0.9 million compared to 2024, which was primarily driven by a short-term bank loan.

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 September 30, 2025, we do not expect to terminate the contract with NFS before the end of the contract term. Refer to Note 12 – Deferred Contract Incentive and Note 18 – Commitments, Contingencies and Other for additional detail.

Effective June 2023, 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 five-year period ending June 2028, with an option to terminate after three years. As of September 30, 2025, the total remaining minimum expense for this arrangement is estimated at approximately $0.3 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 and nine months ended September 30, 2025 and 2024. 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 September 30, 2025 and December 31, 2024, we recorded an uncertain tax position of $1,354,000 related to various tax matters, which is included in the line item “Taxes payable” in the statements of financial condition.

Tax Legislation

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 2024 Form 10-K. As of September 30, 2025, there have been no changes to our critical accounting policies or estimates.

New Accounting Standards

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures” (“ASU 2023-09”). The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 will be effective for us for annual periods beginning after December 15, 2024, though early adoption is permitted. We are still evaluating the presentational effect that ASU 2023-09 will have on our consolidated financial statements, but we expect considerable changes to our income tax footnote.

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. ASU 2024-03 will be effective for us for annual periods beginning after December 15, 2025, though early adoption is permitted. 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 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. We are evaluating the impact of the standard on our financial statements.

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. We are evaluating the impact of the standard on our disclosures.

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 Securities Exchange of 1934, as amended (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.

- 34 -

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.
