**TRADEMARK AND OTHER INFORMATION**

The terms "MIAX," the "Company," "we," "us" and "our" refer to Miami International Holdings, Inc. ("MIH"), together with our wholly-owned subsidiaries. The term "MIAX Exchanges" refers to our SEC regulated exchanges, each a "MIAX Exchange": Miami International Securities Exchange, LLC ("MIAX Options"), MIAX Pearl, LLC ("MIAX Pearl"), the equities trading facility of MIAX Pearl ("MIAX Pearl Equities"), MIAX Emerald, LLC ("MIAX Emerald") and MIAX Sapphire, LLC ("MIAX Sapphire").

We own MIAX<sup>®</sup>, MIAX Options<sup>®</sup>, MIAX Pearl<sup>®</sup>, MIAX Emerald<sup>®</sup> and MIAX Sapphire<sup>®</sup> as trademarks or service marks in the United States and certain other jurisdictions. MIAX Futures™ and TINI™ are currently pending.

This Quarterly Report on Form 10-Q (this "Quarterly Report") contains references to our trademarks and service marks and to those belonging to other entities. Solely for convenience, trademarks and trade names referred to in this Quarterly Report, including logos, artwork, and other visual displays, may appear without the <sup>®</sup> or™ symbols, but in the case of our trademarks and trade names or those of our licensors, such references are not intended to indicate in any way that we will not assert, to the fullest extent under applicable law, our rights or the rights of the applicable licensor to these trademarks and trade names. We do not intend our use or display of other entities' trade names, trademarks, or service marks to imply a relationship with, or endorsement or sponsorship of us by, any other entity.

This Quarterly Report contains estimates and information concerning our industry, including market position, market size and growth rates of the markets in which we participate, that are based on industry publications and reports. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to these estimates. Although we are responsible for all of the disclosure contained in this Quarterly Report and we believe the information from the industry publications and other third-party sources included in this Quarterly Report is reliable, we have not independently verified the accuracy or completeness of the data contained in such sources. Similarly, while we believe our management estimates to be reasonable, they have not been verified by any independent sources. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section titled "Risk Factors" in Part II, Item 1A of this Quarterly Report and our other filings with the Securities and Exchange Commission ("SEC"). These and other factors could cause results to differ materially from those expressed in these publications and reports.

**SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Quarterly Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve a number of risks and uncertainties. You can identify these statements by forward-looking words such as "may," "might," "should," "expect," "plan," "anticipate," "believe," "estimate," "predict," "potential" or "continue," and the negative of these terms and other comparable terminology. All statements that reflect our expectations, assumptions or projections about the future other than statements of historical fact are forward-looking statements, including statements in "Management's Discussion and Analysis of Financial Condition and Results of Operations." These forward-looking statements, which are subject to known and unknown risks, uncertainties, and assumptions about us, may include projections of our future financial performance based on our growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance, or achievements to differ materially from those expressed or implied by the forward-looking statements. In particular, you should consider the risks and uncertainties described under "Risk Factors" in this Quarterly Report and other filings with the SEC.

While we believe we have identified material risks, these risks and uncertainties are not exhaustive. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Some factors that could cause actual results to differ include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our expectations regarding our operating and financial results and performance, competitive position, including pricing within our industry and our ability to maintain profitability and generate profitable growth over time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the sufficiency of our existing capital resources to fund our future operating expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing and success of our new products and product offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes to the regulatory environment and compliance with law and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to attract trading volume to our exchanges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to maintain order flow from our order flow providers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• revenues from our market data fees and access and capacity fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our dependence on third parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in user preferences;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to attract and retain skilled management and other personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to minimize the risks, including credit and default risks, associated with operating a clearing house;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the growth of our business through offering new services and product offerings and acquisitions or strategic alliances;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to invest in technology and keep up with rapid technological changes affecting our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impairment of our goodwill, other intangible assets or investments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the efficacy of our risk management methods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• litigation risks and other liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to protect our intellectual property rights and avoid violating the intellectual property rights of others; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact on our business of global economic, political and financial market events or conditions, including regional conflicts and war.

We do not undertake, and expressly disclaim, any duty to update any forward-looking statement whether as a result of new information, future events or otherwise, except as required by law.

Notes to Condensed Consolidated Financial Statements (unaudited)

**1. NATURE OF OPERATIONS**

On January 20, 2026, the Company completed the sale of 90% of the issued and outstanding equity in LedgerX LLC ("LedgerX") d/b/a MIAX Derivatives Exchange ("MIAXdx") to a joint venture established by Robinhood Markets, Inc. ("Robinhood") in partnership with Susquehanna International Group ("SIG"). MIH has retained 10% of the issued and outstanding equity of MIAXdx, now known as Rothera Exchange and Clearing LLC.

On June 5, 2025, the Company acquired International Stock Exchange Group Limited ("TISEG"), which operates TISE, an investment exchange which is regulated by the Guernsey Financial Services Commission ("GFSC") ("TISE Acquistion").

On August 15, 2025, the Company closed its initial public offering (the "IPO").

The Company is headquartered in Princeton, New Jersey with principal offices in Miami, Minneapolis, Chicago, Hamilton, Bermuda and St. Peter Port, Guernsey.

**2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

***Basis of Presentation***

These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts and transactions of the Company and its majority owned subsidiaries. These unaudited condensed consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements and the accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. As of March 31, 2026, there have been no material changes in the Company's significant accounting policies from those that were disclosed in its audited annual consolidated financial statements for the year ended December 31, 2025.

In preparing the condensed consolidated financial statements, all significant intercompany accounts and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements reflect all adjustments that are, in the Company's opinion, necessary for a fair presentation of results for the interim periods presented. The Company believes these adjustments are of a normal recurring nature.

***Use of Estimates***

The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. These estimates are based on historical experience, and other assumptions that management believes to be reasonable under the circumstances, which together form the basis for making judgments about the carrying values of assets and liabilities.

Assumptions and estimates used in preparing the condensed consolidated financial statements include those related to the reserve for credit losses on receivables, useful lives and impairment of fixed assets, the capitalization and estimated useful life of internally developed software, the valuation of puttable common stock and puttable warrants issued with debt, the recognition and measurement of goodwill and intangible assets, impairment of long-term investments, the valuation and recognition of share-based compensation, the discount rate used for operating leases, the recognition and measurement of current and deferred income tax assets and liabilities, and the valuation of derivative assets. Actual results could differ from these estimates and could have a material adverse effect on the Company's condensed consolidated financial statements.

***Segment Information***

The Company has four business segments: Options, Equities, Futures and International, which is reflective of how the Company's chief operating decision-maker ("CODM") reviews and operates the business. See Note 18 - Segment Reporting for more information. Substantially all of the Company's revenues and assets are attributed to or located in the United States.

***Recent Accounting Pronouncements***

*Recent Accounting Pronouncements – Adopted by the Company*

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2023-08, Intangibles—Goodwill and Other—Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets ("ASU 350-60"), which addresses the accounting and disclosure requirements for certain crypto assets. The amendments are effective for fiscal years beginning after December 15, 2024, including interim periods within that year, which require the Company to measure crypto assets that meet the scope criteria at fair value and to reflect changes in fair value in net income each reporting period. The amendments in ASU 350-60 also require the Company to present crypto assets measured at fair value separately from other intangible assets on the balance sheet and changes in the fair value measurement of crypto assets separately from changes in the carrying amounts of other intangible assets on the income statement. The adoption of the standard beginning fiscal year 2025, did not have any material impact on the Company's condensed consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which amends annual income tax disclosure requirements to include disaggregated information about the Company's effective tax rate reconciliation and income taxes paid. The Company adopted ASU 2023-09 retrospectively beginning fiscal year 2025 and included the necessary disclosures in its annual consolidated financial statements for the year ended December 31, 2025. ASU 2023-09 did not have any impact on the Company's financial position or results of operations. The disclosures are required on an annual basis and therefore had no impact on the Company's interim condensed consolidated financial statements.

*Recent Accounting Pronouncements - Not yet adopted by the Company*

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures. ASU 2024-03 amends ASC 220, Comprehensive Income to expand income statement expense disclosures and require disclosure in the notes to the financial statements of specified information about certain costs and expenses. ASU 2024-03 is required to be adopted for fiscal years commencing after December 15, 2026 and interim reporting periods beginning after December 15, 2027 with early adoption permitted. The Company expects to adopt the update for the annual financial statements issued for the year ending December 31, 2027 and is currently evaluating the impact of adopting the standard on the consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software. The accounting improvements replace the development-stage-based guidance with a principles-based "probable-to-complete" capitalization threshold and clarify disclosure requirements for capitalized internal-use software. ASU 2025-06 is effective for annual periods beginning after December 15, 2027 and for interim reporting periods within those annual periods, with early adoption permitted. The Company expects to adopt the update for the interim and annual financial statements issued for the year ending December 31, 2028 and is currently evaluating the impact of adopting the standard on the consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) - Narrow Scope Improvements which amends and clarifies the interim disclosure requirements of ASC 270. The standard provides clarity about current requirements to help entities determine whether disclosures not specified in ASC 270 should be provided in interim reporting periods. This update is effective for interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of adopting this standard on the condensed consolidated financial statements.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements which makes improvements to the Accounting Standards Codification ("ASC") for a broad range of Topics arising from technical corrections, unintended application of the Codification, clarifications, and other minor improvements. This update is effective for annual reporting

periods beginning after December 15, 2026, including interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact of adopting this standard on the consolidated financial statements.

**3. BUSINESS COMBINATIONS AND DISPOSITIONS**

***TISE Acquisition***

On June 5, 2025, the Company through one of its wholly-owned subsidiaries completed its acquisition of TISEG, an entity that provides financial markets and securities services to public and private companies through operation of an investment exchange known as TISE. TISE is regulated by the GFSC and headquartered in Guernsey. The acquisition of TISE provides the Company access to the European and UK markets, as well as access to another vertically integrated market ecosystem.

Prior to the TISE Acquisition, the Company, through one of its wholly-owned subsidiaries owned 29.46% of the issued ordinary share capital in TISE. The Company remeasured such pre-existing equity interest at fair value of $25.5 million based on the purchase price. The total cash consideration paid for the remaining issued and to be issued ordinary share capital of TISE was £51.5 million ($69.7 million).

The acquisition was accounted for as a business combination. Assets acquired totaled approximately $116.1 million, including $18.0 million of goodwill and $76.0 million of intangible assets. The goodwill generated in the acquisition is not tax deductible. Total liabilities assumed amounted to approximately $20.9 million.

For the three months ended March 31, 2025, the Company incurred acquisition costs of $0.7 million. These costs included legal and other professional services directly related to the acquisition of TISE and were recognized in acquisition-related costs in the Company's condensed consolidated statement of operations.

***Disposition of MIAXdx***

On November 25, 2025, M 7 Holdings, a wholly-owned subsidiary of the Company, entered into a definitive agreement to sell 90% of the issued and outstanding equity of MIAXdx to a joint venture established by Robinhood in partnership with SIG. The Company has retained 10% of the issued and outstanding equity of MIAXdx, now known as Rothera Exchange and Clearing LLC ("Rothera") (such transaction, the "MIAXdx Transaction"). The sale of MIAXdx closed on January 20, 2026. See Note 6 - Investments for further details on the Company's equity interest in Rothera.

The total assets of $41.0 million and total liabilities of $2.8 million of MIAXdx were segregated and presented separately as assets held for sale and liabilities held for sale, respectively, in the condensed consolidated balance sheet as of December 31, 2025. The assets held for sale were recorded at their carrying value as it was lower than the estimated fair value less cost to sell.

In connection with the sale of MIAXdx, the Company received cash consideration of $59.8 million, net of cash and cash equivalents sold, and recognized a gain of $50.5 million in the condensed consolidated statement of operations for the three months ended March 31, 2026.

**4. REVENUE RECOGNITION**

The Company primarily generates revenues by assessing fees to its member firms for the services it renders, which include providing access to its exchanges, enabling transaction-based trading on its exchanges, and providing access to various market data. Revenue for the Company's services are recognized as control of the services are transferred to the customer. The amount recognized is the amount that reflects the consideration the Company expects to be entitled to in exchange for its services.

The Company determines the transaction price at the outset of the arrangement based on the contractual and payment terms associated with the transaction. The typical term for the Company's contracts with customers ranges from the time it takes to complete a single transaction to one month, depending on the service being provided. Customers are usually billed each month in arrears with standard payment terms, although the Company does occasionally bill customers in advance. Fees associated with each contract are fixed within the month in which the service is provided. The Company assesses the services promised in the contracts with customers and identifies a performance obligation for each promise to transfer to the customer a service that is distinct — i.e., if such service is separately identifiable and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

*Transaction and clearing fees*: Transaction fees represent fees the Company charges to its exchange member firms, as customers, for the performance obligation of executing a trade on the Company's exchanges and comprise the majority of the Company's revenues. These fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis in accordance with the Company's published fee schedules. Transaction fees also include Dorman Trading's sales and brokerage commissions generated by customers' trading activity on options and futures. Commission revenue is reported on a gross basis as the Company is responsible for the execution of the customers' purchases and sales and maintaining relationships with exchanges. Transaction fees are recognized across all operating segments and are recorded as transactions occur on a trade-date basis.

Clearing fees, which include settlement fees, are charged by the Company for transactions cleared by MIAX Futures, Dorman Trading and BSX. Clearing fees can be variable based on cleared volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded and billed on a monthly basis in accordance with the Company's published fee schedules. Clearing fees that are passed through to the customers' accounts are reported gross on the Company's condensed consolidated statements of operations as the Company maintains control over the clearing and execution services provided, maintains relationships with the exchanges or clearing brokers, and has ultimate discretion in whether the fees are passed through to the customers and the rates at which they are passed through. Clearing fees are recognized in the Futures segment for MIAX Futures and Dorman Trading and in the International segment for BSX and are recorded as transactions are cleared.

Tiered discounts are offered to customers based on the amount of trades that are executed on the Company's exchanges. As these are volume driven, they reduce the transaction price and are recorded net within transaction fees on the condensed consolidated statements of operations. Liquidity payments paid for certain customer transactions are accounted for as consideration payable to a customer and are recorded separately as liquidity payments, which are classified within cost of revenue in the condensed consolidated statements of operations.

Transaction and clearing fees also result in regulatory fees. Regulatory fees include the options regulatory fee ("ORF") and Section 31 fees. ORF is in place to fund the Company's regulatory oversight function of the exchange marketplace and is determined based on the number of customer contracts and cannot be used for non-regulatory purposes. Section 31 fees are transaction fees charged by the SEC to the exchanges. The Section 31 fees charged to customers are based on the fee set by the SEC per notional value of transactions executed on the Company's securities markets and are calculated and billed monthly. The Section 31 fees collected by the Company are ultimately payable to the SEC and are therefore classified within cost of revenue in the condensed consolidated statements of operations. Beginning on May 14, 2025, the rate was reduced from $27.80 per million for covered sales to a rate of $0.00 per million. This reduction was a temporary adjustment with the fee reverting to a new rate once legislation for fiscal year 2026 appropriation was enacted. On February 27, 2026, the SEC announced that starting on April 4, 2026, the new fee rates would be set at $20.60 per million for covered sales.

*Access fees*: Access fees include fees assessed for allowing customers, which include exchange member firms and non-member firms, to connect their networks to one of the Company's exchanges or to an external exchange for a specified period of time. Fees for these services are assessed to customers for the opportunity to trade as member firms, or in the case of non-member firms to provide these services to member firms and use other related functions of the exchanges. Access fees are billed monthly in accordance with the Company's published fee schedules and recognized during the period the service is provided, which is generally one month. Access fees are recognized across all operating segments.

*Market data fees*: Market data fees include making market data available to customers either through direct subscriptions, through third party platforms or through the Company's participation in the Consolidated Tape Association ("CTA") Plan, the Unlisted Trading Privileges ("UTP") Plan, and the Consolidated Quotation System ("CQS") Plan and the Options Price Regulatory ("OPRA") Plan (collectively the "U.S. Tape Plans"). Market data revenue includes distributions from the U.S. Tape Plans, which is distributed based upon each individual exchange's market share of U.S. volume, trades, and/or quotes. Market data revenue also includes market data revenue earned from the sale of proprietary market data directly to the customer on a subscription or ad-hoc basis or from third parties where the Company is the principal in the transaction. Market data revenue is recognized in the period the data is provided. U.S. Tape Plan market data is recognized in the Options and Equities segments. Proprietary market data fees are recognized across all operating segments.

*Other revenue*: Other revenue primarily includes initial and annual listing fees from TISE, MIAX Futures and BSX listings, member fines, office rental income and interest income from MIAX Futures and Dorman Trading clearing

operations. Initial listing fees are billed upfront and recognized as revenue when the performance obligations are satisfied upon the listing becoming effective, which occurs shortly after the contract execution. Annual listing fees are recognized on a straight-line basis over the period to which the fee relates. Member fines are not available for general corporate purposes and can only be used to offset the cost of the MIAX Exchange's regulatory operations.

*Consideration payable to a customer*: As discussed in the transaction and clearing fees section above, liquidity payments are accounted for as consideration payable to a customer and are recorded separately as liquidity payments within cost of revenues in the condensed consolidated statements of operations in the period in which the payment is earned by the customer and the payment is provided. In certain instances, including for new segments and proprietary products, liquidity payments may exceed transaction fees resulting in inverted pricing. The Company considers liquidity payments to be a distinct transaction. The Company believes that providing (or removing) liquidity is a distinct service that is provided by customers, as the Company benefits from having an enhanced liquidity pool available on its markets, and that it is separately identifiable given its separation on the published fee schedules. The Company believes that the enhanced liquidity pool attracts order flow and promotes order execution on the Company's trading platforms. Through enhanced order flow, and therefore higher market share, the Company also earns additional market data fees and access fees.

The following table summarizes revenue disaggregated by the Company's Options, Equities, Futures and International segments and the Corporate and Other unit (in thousands):

Deferred transaction revenue consists of prepaid transaction and non-transaction fees which are recognized as revenue when earned. During the three months ended March 31, 2026, the Company received prepaid fees of $5.2 million and recognized deferred transaction revenue of $4.8 million. During the three months ended March 31, 2025, the Company received prepaid fees of $1.6 million and recognized deferred transaction revenue of $1.1 million.

*Concentration of revenue*: For the three months ended March 31, 2026, the Company derived $166.7 million of the $369.7 million in total revenue from three customers, with such customers accounting for 17%, 16% and 12% of the Company's total revenue. For the three months ended March 31, 2025, the Company derived $143.6 million of the $327.1 million in total revenue from three customers, with such customers accounting for 18%, 13% and 12% of the Company's total revenue.

Revenues from transactions with the top three customers for the three months ended March 31, 2026 and 2025, are reported primarily within the Options segment. No customer is contractually or otherwise obligated to continue to use the Company's services. The loss of, or a significant reduction of, participation by these customers may have a material adverse effect on the Company's business, financial position, results of operations and cash flows.

**6. INVESTMENTS**

From time to time the Company makes investments in entities of strategic relevance. These investments primarily consist of illiquid and non-controlling positions in entities with no readily determinable fair value, which are carried at cost less any impairment and are adjusted for observable price changes from orderly transactions for identical or similar securities. As of March 31, 2026 and December 31, 2025, the carrying amount of investments made by the Company was $29.2 million and $19.2 million, respectively.

On November 25, 2025, M 7 Holdings, LLC, a wholly-owned subsidiary of the Company, entered into a definitive agreement to sell 90% of the issued and outstanding equity of MIAXdx to a joint venture established by Robinhood Markets, Inc. in partnership with Susquehanna International Group. The Company retained 10% of the issued and outstanding equity of MIAXdx, now known as Rothera for a carrying value of $10.0 million. The MIAXdx Transaction closed on January 20, 2026. At any time during the three-year period following the closing date, the Company has the right to sell to the buyer all, but not less than all, of its retained equity interest at a predetermined valuation. During the same three-year period, the buyer has the right to acquire 50% of the Company's retained equity interest at a separately predetermined valuation.

Notes to Condensed Consolidated Financial Statements (unaudited)

The notes receivable relates to the Consolidated Audit Trail ("CAT"), which involves the creation of an audit trail to enhance regulators' ability to monitor trading activities in the U.S. markets through a phased implementation. The funding for the development and operation of the CAT was provided by the Self-Regulatory Organizations ("SROs"), which include the Company's exchanges and by broker-dealers in exchange for promissory notes, a portion of which are expected to be repaid by Consolidated Audit Trail, LLC ("CAT LLC").

In 2016, the SEC approved a plan to establish CAT to improve regulators' ability to monitor trading activity. Each of the MIAX Exchanges is a participant in the CAT NMS Plan, which governs the collection, consolidation, and retention of all information reported to CAT pursuant to Securities Exchange Act of 1934, as amended (the "Exchange Act") Rule 613 for securities listed on the MIAX Exchanges. In 2018, the first phase of CAT went live and required SRO participants to begin reporting to the CAT. The SRO participants jointly own a limited liability company, CAT LLC, which conducts the activities of the CAT. Implementation and operation of the CAT has resulted in significant expenditures by the MIAX Exchanges.

On September 6, 2023, the SEC approved a revised funding model ("2023 Funding Order"), called the "Executed Share Model," for the SRO participants and the industry to share CAT costs. The Executed Share Model established a framework that SRO plan participants may use to recover the costs to create, develop, and maintain the CAT, as well as a method for allocating CAT costs among the SRO participants and the industry. Prior to the effectiveness of the Executed Share Model, funding was provided solely by the SROs, partly in exchange for promissory notes.

Under the Executed Share Model, the SRO participants were able to submit filings pursuant to Section 19(b) of the Exchange Act to impose fees on the industry members. Details of the fees, including the budgeted prospective CAT costs and certain of the costs previously covered entirely by the SRO participants, were required to be provided in those Section 19(b) filings. On October 17, 2023, the 2023 Funding Order was challenged in the 11th Circuit U.S. Court of Appeals ("11th Circuit").

In August 2024, the SRO participants submitted filings with the SEC to recoup certain historical CAT costs incurred prior to January 1, 2022, and prospective CAT costs from July 26, 2024, through December 31, 2024. In December 2024, the SROs submitted filings with the SEC to recoup certain prospective CAT costs from January 1, 2025, through June 30, 2025. In June 2025, the SROs submitted filings with the SEC to recoup certain prospective CAT costs from July 1, 2025, through December 31, 2025. On July 25, 2025, the 11th Circuit issued an opinion that the Executed Share Model is arbitrary and in violation of the Administrative Procedures Act. The 11th Circuit thus vacated the 2023 Funding Order, stayed the decision for sixty days after issuance of the mandate, and remanded the matter to the SEC for further proceedings consistent with their opinion.

On September 5, 2025, CAT LLC filed with the SEC a proposed amendment to implement a revised funding model (the "Amendment"). On November 21, 2025, the SEC issued an order instituting proceedings to determine whether to approve or disapprove the Amendment. On March 16, 2026, the SEC approved the proposed revised funding model addressing the 11th Circuit's concerns and limited the funding model's operation to two years while the SEC conducts a comprehensive review of the CAT. The SEC's approval order also requires that historical costs must be recouped over a period of two to five years. That means historical costs cannot be fully recouped if the collection period is shortened beyond the approval order's two-year limitation. On April 1, 2026, CAT LLC issued fee alerts announcing its intent to establish CAT fees consistent with the SEC's approval order; these fees will apply to May 2026 trading activity, with bills due in July 2026.

On March 25, 2026, petitioners American Securities Association and Citadel Securities LLC filed a new petition for review in the 11th Circuit of the SEC's approval of the CAT's revised funding model. If the new petition is successful, the MIAX Exchanges could be required to stop charging both historical and prospective CAT fees. As a result, the SROs, including the MIAX Exchanges, may continue to incur significant costs and not be reimbursed for prospective and historical CAT costs.

On September 30, 2025, the SEC issued an order allowing the SRO participants to reduce CAT operating costs while retaining the CAT's core regulatory functionality. On December 18, 2025, CAT LLC filed with the SEC a proposed amendment to further reduce CAT operating costs. On March 27, 2026, the SEC approved this proposed amendment.

On April 16, 2024, certain plaintiffs petitioned the United States District Court for the Western District of Texas Waco Division to completely shut down CAT based on constitutional grounds ("Waco Case"). The Waco Case was stayed until January 15, 2026. On January 15, 2026, certain of the defendants motioned the court to continue the stay until July 2026,

which plaintiffs oppose. The Waco Case is still pending, and may result in the CAT SRO participants being unable to recoup any CAT costs, as well as incurring addition costs related to CAT.

***2029 Senior Secured Term Loan***

In August 2024, the Company entered into a $100 million senior secured term loan (the "2029 Senior Secured Term Loan"), which bore interest at 12.90% per annum and was scheduled to mature in August 2029. In June 2025, the Company entered into an amendment to obtain an additional $40 million incremental term loan on substantially similar terms.

In connection with the 2029 Senior Secured Term Loan, the Company issued to the lenders warrants to purchase up to 2,277,338 and 1,518,226 shares of common stock with exercise prices equal to $7.15 and $8.55 per share, respectively. The warrants had an associated put right in which the lenders had the right to require the Company to redeem any unexercised portion of the warrants for a purchase price equal to its fair value. The put right terminated upon the completion of the Company's IPO in August 2025.

Prior to the IPO, the puttable warrants were classified as a liability and remeasured at fair value each reporting period, with any change in the fair value recognized as a component of non-operating income (expense) in the consolidated statements of operations. Upon completion of the IPO, the puttable warrant liability was reclassified to equity.

On August 18, 2025, the Company used proceeds from the IPO to repay the entire outstanding balance of the 2029 Senior Secured Term Loan, including the incremental term loan, for total consideration of $178.4 million, which included accrued interest and a prepayment premium. The Company recorded a loss on debt extinguishment of $107.7 million during the year ended December 31, 2025.

In December 2025, in connection with a secondary offering completed by the Company, the lenders exercised an aggregate of 3,690,079 warrants on a cashless basis, resulting in the issuance of 3,065,826 shares of the Company's common stock. During the first quarter of 2026, the lenders exercised the remaining outstanding warrants, resulting in no warrants outstanding as of March 31, 2026.

The Company recognized $4.2 million of interest expense related to the 2029 Senior Secured Term Loan during the three months ended March 31, 2025, including $0.9 million related to the accretion of the debt discounts and deferred financing costs.

***Convertible loans***

During the year ended December 31, 2020, the Company issued a 9.5% convertible loan for $5.0 million to an existing stockholder due five years from the date of issuance. Interest was payable quarterly and the loan was convertible into the Company's common stock at the option of the holder at a price of $16.00 per share. In December 2025, the lender converted the entire $5.0 million of outstanding principal into 312,500 shares of common stock at a conversion price of $16.00 per share. The total accrued and unpaid interest was $0.1 million as of the date of conversion, which was converted into 5,287 shares of the Company's common stock. The Company recognized interest expense amounting to $0.2 million related to the convertible loans for the three months ended March 31, 2025.

***Notes Payable***

In December 2023, the Company issued a $1.5 million promissory note at an interest rate of 8% to an existing stockholder due three years from the date of issuance. Interest is payable on a semi-annual basis in cash or shares of the Company's common stock at the price of $20.50 per share at the option of the holder. The Company issued 7,408 warrants to purchase common stock at an exercise price of $20.50 per share to the lender. The fair value of the warrants issued was immaterial, which was recorded as debt discount and is being amortized over the term of the loan. Interest expense and the amortization of debt discount was immaterial both the three months ended March 31, 2026 and 2025.

***Lines of Credit***

As of March 31, 2026, MIAX Futures maintained two unsecured revolving lines of credit with a bank, one for $6.0 million and another for $4.0 million. Both unsecured lines of credit expire on December 31, 2027. Borrowings bear interest at the bank's prime rate less 0.25% (effective rate of 6.50% as of both March 31, 2026 and December 31, 2025) and have an annual commitment fee of 0.40%. MIAX Futures also maintains a secured line of credit with another bank for $40 million which will expire on July 28, 2026. The secured line of credit carries an interest at the bank's prime rate of 6.75% as of both March 31, 2026 and December 31, 2025, and an annual commitment fee of 0.25% through July 2026. At March 31, 2026 and December 31, 2025, there were no amounts outstanding on any lines of credit.

No interest expense was incurred related to the above lines of credit for the three months ended March 31, 2026 and 2025. MIAX Futures is required to maintain certain financial minimums and restrictions. MIAX Futures complied with all such covenants as of March 31, 2026.

As of March 31, 2026, Dorman Trading maintained an unsecured revolving line of credit for $10.0 million at an interest rate equal to the bank's prime rate. If the loans are not repaid when due, the interest rate would be determined by adding 3.0% to the prime rate. There was no amount outstanding as of March 31, 2026 and December 31, 2025 and Dorman Trading did not incur any interest expense during the three months ended March 31, 2026 and 2025.

In 2021, BSX entered into agreements with a wholly owned subsidiary of Pyth Data Foundation ("Pyth") to provide certain data to the Pyth Network in exchange for 500 million Pyth tokens. During 2023, pursuant to a replacement token agreement, BSX received 500 million replacement Pyth tokens which were locked and restricted from trading with a four year unlock schedule commencing on May 20, 2024. While the Pyth tokens are locked they are not in the control or possession of BSX, cannot be traded by BSX, and are held by another entity. The Pyth tokens unlock on the schedule based

Notes to Condensed Consolidated Financial Statements (unaudited)

on the agreement under which they were issued, and do not require any further performance by BSX in order to receive the Pyth tokens as they unlock. Locked Pyth tokens are considered the right to receive crypto tokens.

On May 20, 2025, the second tranche of the 125 million right to receive Pyth tokens were unlocked by the Pyth Network and BSX sold the entire 125 million tokens for $16.2 million, net of expenses incurred. The Company recorded a loss on sale of $2.1 million, which was the difference between the fair value of the derivative assets and the net proceeds received. The loss on sale of intangible asset was recorded in non-operating (expense) income on the condensed consolidated statement of operations.

The remaining 250 million locked Pyth tokens as of March 31, 2026 are expected to be unlocked at a rate of 125 million tokens on each of the next two unlock anniversary dates of May 20, 2026 and 2027. The Company received an additional 1.2 million locked reward Pyth tokens, which will be unlocked at various times during 2026 through 2028. When BSX becomes entitled to the right to receive crypto tokens, it assesses if such right includes an embedded feature that meets the definition of a derivative requiring separate accounting treatment. At each reporting date, BSX reevaluates its conclusion on whether there is an embedded derivative based on current facts and circumstances. During the second quarter of 2024, an active market emerged for Pyth tokens, the crypto tokens in which BSX has outstanding rights to receive in exchange for its previous services to certain customers. Prior to the existence of an active market, BSX concluded that the right to receive crypto tokens did not meet the definition of a derivative as there was no market mechanism to net settle the contract so therefore it was not separately accounted for as an embedded derivative. Once an active market was established in the second quarter of 2024, BSX determined that the right to receive crypto tokens included an embedded derivative to be separately accounted for in accordance with Accounting Standard Codification ("ASC") 815, Derivatives and Hedging. The embedded derivatives are recognized at fair value at each reporting date and recorded in derivative assets (current and noncurrent) in the condensed consolidated balance sheets. Changes in the fair value of the embedded derivatives are reported in unrealized loss on derivative assets in the condensed consolidated statements of operations.

As of March 31, 2026 and December 31, 2025, the Company recognized the fair value of derivative assets on the condensed consolidated balance sheets amounting to $8.6 million and $11.1 million. The corresponding change in fair value during the three months ended March 31, 2026 and 2025 resulted in a loss of $2.5 million and $42.4 million and was recorded in unrealized loss on derivative assets within non-operating (expense) income on the condensed consolidated statements of operations. The derivative assets are classified as current or noncurrent in the condensed consolidated balance sheets based on the timing when tranches of Pyth tokens are expected to unlock.

**12. EMPLOYEE BENEFIT PLAN**

The Company maintains a voluntary defined contribution 401(k) plan in which employees may contribute up to 100% of their salary and bonus, subject to statutory maximum contribution amounts. The Company matches 50% of the first 6% of employee contributions. The expense relating to the matching contribution was $0.8 million and $0.6 million for the three months ended March 31, 2026 and 2025, respectively.

**13. CLEARING HOUSE PERFORMANCE BONDS AND GUARANTEE FUNDS** 

Clearing members involved in clearing commodity futures and options are required to provide margin and security deposits with the clearing house as performance bonds and guarantee funds in order to meet their financial obligations and as protection against potential losses or default. MIAX Futures policy allows clearing members to deposit cash or U.S. Treasury Bills in order to satisfy the required margin and security deposits.

As of March 31, 2026 and December 31, 2025, the Company had performance bonds and guarantee funds totaling $335.3 million and $305.7 million respectively, as summarized below (in thousands):

__________________

1. The U.S. Treasury Bills are not reflected in the condensed consolidated balance sheets, as MIAX Futures does not take economic ownership of these securities or have the right to sell or re-pledge.

MIAX Futures is required, under the Commodity Exchange Act, to segregate cash and securities deposited by clearing members on behalf of their customers. Exchange rules require a segregation of all funds deposited by clearing members from operating funds. The amount of cash and securities deposited may fluctuate significantly over time due to the quantity of open MIAX Futures positions, margin and security requirements, investment choices by clearing members, and market valuations of securities.

Cash deposited as performance bonds and guarantee funds is included on the condensed consolidated balance sheets because the cash is deposited in MIAX Futures controlled bank accounts. MIAX Futures at its discretion, may distribute interest earned on the cash balances that are posted for margin and security deposits. MIAX Futures distributed interest amounting to $0.2 million for both the three months ended March 31, 2026 and 2025, which is reflected within other cost of revenues in the condensed consolidated statements of operations. U.S. Treasury Bills deposited by the clearing members are not reflected on the condensed consolidated balance sheets as MIAX Futures does not take economic ownership of these securities or have the right to sell or re-pledge, and MIAX Futures does not earn interest on them. These U.S. Treasury Bills are held at a nominee account in MIAX Futures' name for the benefit of the clearing members and are immediately accessible by MIAX Futures in the event of a default.

1&nbsp;&nbsp;&nbsp;&nbsp;These amounts are reflected within other current assets in the condensed consolidated balance sheets.

Equity securities that trade in active markets and are valued using quoted market prices with reasonable levels of price transparency are classified within Level 1 of the fair value hierarchy.

As disclosed in Note 11, during 2023, BSX received 500 million Pyth tokens, of which 125 million were unlocked in May 2024 and another 125 million were unlocked in May 2025. As of March 31, 2026 and December 31, 2025, 250 million tokens remain unlocked. The entire locked Pyth tokens were accounted for as an embedded derivative recognized at fair value at March 31, 2026 and December 31, 2025. In estimating the fair value of the right to receive Pyth tokens which

are classified under Level 2, the Company applied a discount for lack of marketability using option pricing models utilizing observable inputs which include comparable tokens and their volatility.

Certain financial assets and liabilities, including cash and cash equivalents, accounts receivable and accounts payable are not measured at fair value on a recurring basis, but the carrying values approximate fair value due to their liquid or short-term nature.

***Assets and Liabilities Measured at Fair Value on a Non-recurring Basis***

The Company invests in securities without readily determinable fair values in which the carrying value was $29.2 million and $19.2 million as of March 31, 2026 and December 31, 2025, respectively. There were no impairments or adjustments to the carrying value of the investments without readily determinable fair values during the three months ended March 31, 2026 and 2025.

The Company's long-lived assets, including fixed assets, goodwill, indefinite-lived intangible and finite-lived intangible assets subject to amortization, are measured at fair value on a non-recurring basis. Fair value of these assets is estimated using primarily unobservable inputs. These assets are measured at cost but are written-down to fair value, if necessary, as a result of impairment.

The Company assesses fair value of goodwill at the reporting unit level annually unless there is a triggering event. The Company may use both qualitative and quantitative approaches when testing goodwill and indefinite-lived intangible assets for impairment. When a qualitative impairment assessment for goodwill and indefinite-lived intangible assets was performed at October 1, 2025, the Company considered relevant events and circumstances, including macroeconomic conditions, industry and market trends, overall financial performance, changes in key assumptions, and other entity-specific factors. Based on this qualitative assessment, the Company concluded that it was not more likely than not that the fair value of any reporting unit or indefinite-lived intangible asset was less than its carrying amount. Accordingly, no quantitative impairment testing was performed and no impairment charges were recorded in 2025.

When the quantitative approach is used, the fair value of a reporting unit is determined utilizing a combination of an income approach (i.e. discounted cash flow) and a market approach, and compared to its carrying value. Internal operational budgets and long-range strategic plans are used as a basis for the discounted cash flow analysis. The Company also utilizes assumptions for working capital, capital expenditures, and terminal growth rates. When the quantitative approach is used, the fair value of indefinite-lived intangibles, which consists of exchange licenses, is determined by estimating the future cash flows and discounting the net cash flows back to their present values or using a market approach, as appropriate.

***Fair Value of Assets and Liabilities***

The Company's debt obligations are comprised of notes payable which is presented at carrying value on the Company's condensed consolidated balance sheets. The carrying values and fair values of the Company's debt obligations are as follows (in thousands):

**15. COMMITMENTS AND CONTINGENCIES**

***Purchase Commitments***

The Company from time to time enters into long term agreements with vendors to provide certain services. As of March 31, 2026, the outstanding commitment was $12.8 million, of which $2.1 million is payable in 2026, $2.1 million in 2027, $1.9 million in 2028, $1.8 million in 2029, $1.6 million in 2030 and $3.3 million in 2031 and beyond.

***MIAX Futures Guaranty Fund***

In the event of default by a clearing member, MIAX Futures would first apply assets of the defaulting clearing member to satisfy its payment obligation. These assets include the defaulting member's security deposits, margins, performance

bonds and any other available assets. Thereafter, if a loss remains, MIAX Futures would use funds of the MIAX Futures clearing house reserve fund, security deposits of non-defaulting clearing members, and in certain instances, surplus funds of MIAX Futures, in the order of priority listed by rules, with each source of funds to be completely exhausted, to the extent practical, before the next source is applied.

MIAX Futures is a Designated Contract Market ("DCM") and a Derivatives Clearing Organization ("DCO") that operate under the regulatory oversight of the Commodity Futures Trading Commission ("CFTC"). As such, MIAX Futures is required to maintain financial resources to cover its projected operating costs for a period of at least one year. The financial resources must include unencumbered, liquid financial assets which may include a committed line of credit or similar facility equal to at least six months of its projected operating costs. At March 31, 2026, MIAX Futures was in compliance with all DCM and DCO financial requirements.

***Derivative Contracts***

Certain derivative contracts that the Company has entered into meet the accounting definition of a guarantee under ASC 460. Derivatives that meet the ASC 460 definition of guarantees include futures contracts and written options. The maximum potential payout for these derivative contracts cannot be estimated as increases in interest rates, foreign exchange rates, securities prices, commodities prices and indices in the future could possibly be unlimited.

The Company records all derivative contracts at fair value. For this reason, the Company does not monitor its risk exposure to derivatives contracts based on derivative notional amounts; rather the Company manages its risk exposure on a fair value basis. The Company believes that the notional amounts of the derivative contracts generally overstate its exposure. Aggregate market risk limits have been established, and market risk measures are routinely monitored against these limits. The Company believes that market risk is substantially diminished when all financial instruments are aggregated.

***Dorman Trading Member Guarantees***

Dorman Trading is a member of various exchanges that trade and clear futures contracts. Dorman Trading may be required to pay a proportionate share of the financial obligations of another member who may default on its obligation to the exchange in accordance with the rules of the applicable exchange of which Dorman Trading is a member. Although the rules governing different exchange memberships vary, in general Dorman Trading's guarantee obligations would arise only if the exchange had previously exhausted its resources. In addition, any such guarantee obligation would be apportioned among the other non-defaulting members of the exchange. Any potential contingent liability under these membership agreements cannot be estimated. The Company has not recorded any contingent liability in the condensed consolidated financial statements for these agreements. The Company believes that any potential requirement to make payments under these agreements is remote.

***Dorman Trading Minimum Capital Requirements***

The Company's subsidiary, Dorman Trading, as a futures commission merchant is subject to CFTC minimum capital requirements of the CFTC Regulation 1.17 ("Regulation 1.17"). Dorman Trading is required to maintain "net capital" equivalent to the greater of $1,000,000 or the sum of 8% of the customer risk maintenance margin requirement plus 8% of the non-customer risk maintenance margin requirement, as these terms are defined. In addition, Dorman Trading is subject to the minimum capital requirements of the exchanges on which Dorman Trading does business.

At March 31, 2026 and December 31, 2025, Dorman Trading had adjusted net capital of $28.5 million and $27.7 million, respectively. Under Regulation 1.17, the net capital requirement at March 31, 2026 and December 31, 2025 was $7.2 million and $4.5 million, respectively. Additionally, as of March 31, 2026 and December 31, 2025, Dorman Trading was in compliance with the minimum capital requirements of the exchanges in which Dorman Trading operates. The net capital rule may effectively restrict member withdrawals and the repayment of subordinated loans.

***Claims and Litigation***

*Nasdaq* 

On September 1, 2017, Nasdaq, Inc. ("Nasdaq") together with its subsidiaries Nasdaq ISE, LLC and FTEN, Inc., filed an action against the Company in the U.S. District Court for the District of New Jersey (the "Court") alleging infringement of seven patents and trade secret misappropriation relating to electronic trading technology and platforms. The Company

Notes to Condensed Consolidated Financial Statements (unaudited)

subsequently filed seven petitions before the Patent Trial and Appeal Board ("PTAB") at the United States Patent and Trademark Office ("USPTO") challenging the validity of the asserted patents. The Court proceeding was stayed in December 2018, pending resolution of the PTAB proceedings. The Court dismissed with prejudice one of the asserted patents from the Court action, and the Company withdrew its petition at the PTAB. All claims asserted by Nasdaq against the Company under the remaining six patents at issue were invalidated by the PTAB in 2019 (the "PTAB Final Written Decisions"). On June 7, 2022, the USPTO Director denied Nasdaq's request for Director review of the PTAB Final Written Decisions.

On August 31, 2021, the Company filed an Answer and Counterclaims in the Court (the "Company's Answer"). The Company's Answer included denials of infringement and trade secret misappropriation and counterclaims by the Company, including claims for antitrust violations, patent misuse, sham litigation, and fraud on the USPTO in procuring the asserted patents. The Company is seeking attorneys' fees and costs and such other relief as the Court may find to be just and proper. On June 21, 2022, Nasdaq waived its right to appeal the PTAB's Final Written Decisions, Nasdaq's patent infringement claims were dismissed with prejudice, and the stay in the Court matter was lifted. The Company filed an Amended Answer and Counterclaims on August 5, 2022. The Amended Counterclaims added claims of fraud on the patent office and Lanham Act violations. On July 25, 2023, the Court denied a motion by the Company to dismiss Nasdaq's remaining trade secret claims and also denied a motion by Nasdaq to dismiss the Company's counterclaims. The Court granted Nasdaq's motion to stay and bifurcate the Company's counterclaims.

The parties each filed motions for summary judgment and motions to exclude certain expert witnesses. On September 29, 2025, the Court denied Nasdaq's and the Company's respective motions for summary judgment, as well as the parties' motions to exclude certain experts. The Court granted Nasdaq's motion to bifurcate the Company's equitable defenses. Subsequently, the Court directed the parties to re-initiate discovery on the Company's counterclaims. The Court further indicated that it intends to preside over one trial with two phases, the first phase addressing Nasdaq's trade secret claims, followed by a second phase in which the Company would present its counterclaims. The Company intends to continue defending its interest in this matter vigorously.

*General*

As a self-regulatory organization under the jurisdiction of the SEC, and as a DCO and DCM under the jurisdiction of the CFTC, and as registered exchanges under the jurisdictions of the Bermuda Monetary Authority ("BMA") and GFSC, each of the MIAX Exchanges, MIAX Futures, BSX and TISE are subject to routine reviews and inspections by the SEC, CFTC, BMA and GFSC, respectively and as applicable. Dorman Trading, as a registered Futures Commission Merchant ("FCM"), is regulated by the CFTC and is subject to routine reviews and inspections by the CFTC and National Futures Association ("NFA"). Management does not believe that the outcome of any of these reviews or inspections will have a material impact on the condensed consolidated financial position, results of operations or cash flows of the Company.

In the normal course of its business, the Company is exposed to asserted and unasserted claims. In the opinion of management, these matters will not have a material adverse effect on the condensed consolidated financial position, results of operations or cash flows of the Company.

**16. EQUITY** 

***Common Stock***

At March 31, 2026 and December 31, 2025, the Company was authorized to issue up to 400,000,000 shares of voting common stock, $0.001 par value per share and 200,000,000 shares of nonvoting common stock, $0.001 par value per share.

As of December 31, 2025, 85,890,086 and 85,536,287 shares of common stock were issued and outstanding, respectively. There were no issued or outstanding shares of nonvoting common stock as of March 31, 2026 and December 31, 2025.

The Company's amended and restated certificate of incorporation contains certain voting and ownership limitations and transfer restrictions that will remain in place for as long as the Company controls a registered U.S. national securities exchange. Specifically, the Company's amended and restated certificate of incorporation prohibits (i) any person from owning greater than 40% of any class of the Company's capital stock, (ii) exchange members from owning greater than 20% of any class of the Company's capital stock and (iii) all persons from voting shares representing more than 20% of the voting power of the Company's then issued and outstanding capital stock either alone or together with any related persons, in each case subject to certain conditions and exceptions, including the waiver by the board of directors (except with

respect to exchange members). Subject to the foregoing limitations, holders of common stock are entitled to one vote per share.

Immediately prior to the completion of the Company's IPO in August 2025, all of the then issued and outstanding shares of the Company's nonvoting common stock and Series B convertible preferred stock were converted into an aggregate of 3,706,117 and 946,959 shares, respectively, of the Company's voting common stock on a one-for-one basis.

As of March 31, 2026 and December 31, 2025, 26,611,922 and 36,256,212 shares of common stock, respectively, were reserved for issuance in connection with warrants, convertible accrued interest and share-based incentive plans.

***Preferred Stock***

The Company is authorized to issue up to 25,000,000 shares of preferred stock $0.001 par value per share in one or more series, as may be designated by the board of directors. There were no issued or outstanding shares of preferred stock as of March 31, 2026 and December 31, 2025.

During the three months ended March 31, 2025, the Company issued 11,568 shares of Series B convertible preferred stock pursuant to cashless exercises of 25,000 options to purchase shares of Series B convertible preferred stock.

In 2010, all outstanding Series A preferred shares were converted into common stock. As part of this conversion, the holders converting Series A preferred shares received contingent promissory notes totaling $15.0 million, which remain outstanding as of March 31, 2026. These contingent promissory notes are only payable, without interest, upon a deemed liquidation event which includes a merger or sale of the Company, therefore expense will only be recognized at such time.

***Treasury Stock***

The Company has generally withheld shares of its common stock to cover employees' portion of required tax withholdings when employee equity awards are issued or vest. These shares are valued at cost, which equals the fair value of the common stock on the date of issuance or vesting and reflected as a reduction to the Company's stockholders' equity and included in treasury stock, at cost in the condensed consolidated balance sheets. The weighted average cost per share held in treasury was $28.46 and $23.27 as of March 31, 2026 and December 31, 2025, respectively.

***Warrants***

The Company issued warrants to purchase shares of common stock primarily in connection with equity rights programs ("ERP", see Equity Rights Program below), stock issuances, certain debt issuances, and consulting agreements. There were outstanding warrants to acquire 6,223,253 and 14,215,311 shares of common stock outstanding at March 31, 2026 and December 31, 2025, respectively.

The warrants vest over time or upon the achievement of performance criteria with respect to certain warrants issued in connection with certain service providers and generally expire at various times through 2030. There were 1,350,000 unvested warrants as of March 31, 2026 and December 31, 2025. The fair value of each warrant grant was derived using the Black-Scholes option pricing model. The Company recorded $0.04 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively, of share-based compensation expense related to warrants issued in connection with consulting agreements.

Effective as of June 30, 2025, the Company entered into an exchange agreement with one of its ERP participants pursuant to which the ERP participant surrendered and the Company canceled and retired 5,887,286 shares of its voting common stock and 331,218 shares of its nonvoting common stock in exchange for a pre-funded warrant to purchase up to 6,218,504 shares of the Company's voting common stock, which had a perpetual term, an exercise price equal to $0.002 per share and a cashless exercise feature. If the Company paid any dividends or otherwise made any pro rata distributions to its stockholders, the holder of the pre-funded warrant was also entitled to receive its share of such dividends or distributions on an as-exercised basis based on the number of shares of the Company's common stock then issuable pursuant to the pre-funded warrant. In August 2025, the ERP participant exchanged an additional 575,071 shares of the Company's voting common stock it purchased from an ERP II participant (then shares of puttable common stock prior to the purchase) for a pre-funded warrant to purchase up to 575,071 shares of the Company's voting common stock with the same terms as the initial pre-funded warrant above (see Equity Rights Program below).

In February 2026, the ERP participant exercised the entire outstanding balance of the pre-funded warrants which were exercisable for an aggregate of 6,793,575 shares of the Company's common stock. Pursuant to cashless exercises, the Company issued an aggregate of 6,793,245 shares of common stock, net of 330 shares surrendered for the exercise price.

During the three months ended March 31, 2026, the Company raised proceeds of $1.2 million through the exercise of 85,386 of previously issued warrants to purchase common stock and issued 721,421 shares of voting common stock pursuant to cashless exercise of 1,103,097 warrants (excluding the warrants exercised by the holder of the pre-funded warrants).

During the three months ended March 31, 2025, the Company issued an aggregate of 5,000 shares of voting common stock for warrants exercised for cash proceeds of $0.1 million. There were no cashless exercise of warrants during the three months ended March 31, 2025.

***Equity Rights Program***

The Company launched five ERPs between September 2013 and September 2020, allowing customers to obtain common stock warrants in return for a prepaid fee applied to future purchases. Warrants vested in tranches based on performance conditions tied to qualifying trade volumes on the Company's exchanges.

The shares of common stock and warrants issued under ERP I and II were classified as liability instruments while those issued under ERP III, IV and V were classified as equity instruments on the Company's condensed consolidated balance sheets. The ERP awards were accounted for as consideration payable to a customer and recorded as cost of revenue over the vesting period based on the grant date fair value of the awards.

*Puttable common stock from exercise of ERP I and II warrants:*

All vested warrants under ERP I and II were exercised before their expiration on August 31, 2020 and January 31, 2022, respectively. The Company recorded the underlying puttable common stock issued upon exercise of the warrants as a liability. ERP I and II participants had a put right to require the Company to purchase a certain percentage of the shares held on the put vesting date in cash at a price per share equal to a fixed percentage of the fair market value of the Company's common stock. The put right terminated upon the completion of the Company's IPO in August 2025, resulting in the extinguishment of the related put liability and its reclassification to equity.

The puttable common stock had been carried at fair value and remeasured at each reporting period until settlement or when the redemption feature was eliminated. The change in fair value was recorded as non-operating income (expense) within the condensed consolidated statements of operations.

In February 2025, an ERP II participant sold 1,150,142 shares of puttable common stock to another ERP participant. In connection with the sale, the put right associated with the shares was terminated. At termination date, the Company remeasured the fair value of the put liability for $25.7 million and recorded the fair value in common stock at par value and additional paid-in capital in the condensed consolidated balance sheet as of December 31, 2025. In August 2025, prior to the Company's IPO, the ERP II participant sold additional 575,071 shares of puttable common stock to the same entity. Immediately following such sale, the ERP participant exchanged those shares with the Company for a pre-funded warrant to purchase up to 575,071 shares of the Company's voting common stock.

*Warrants under ERP III, IV and V:*

The terms of ERP III, IV and V are similar to ERP I and II, except the shares do not have any put right and therefore the ERP III, IV and V awards are equity classified. All vested warrants under ERP III and IV were exercised prior to their expiration on June 30, 2024 and April 30, 2025, respectively.

On September 11, 2020, the Company entered into ERP V where the vesting period ended on June 30, 2024. ERP V warrants expire on the earliest to occur of (i) August 15, 2027 (the two-year anniversary of the Company's IPO) or (ii) a merger or sale of the Company. During the first quarter of 2026, 232,570 warrants were exercised, including the issuance of 190,635 shares of voting common stock pursuant to cashless exercise of 219,995 ERP V warrants. As of March 31, 2026 and December 31, 2025, the number of outstanding ERP V warrants was 280,213 and 512,783, respectively.

**17. SHARE-BASED COMPENSATION**

In accordance with the Company's stock incentive plans, the Company may grant stock option awards to employees, consultants and non-employee members of the Company's Board of Directors. The Company may grant restricted stock awards to employees, consultants and non-employee members of the Company's Board of Directors.

On May 16, 2022, the Company adopted the 2022 Equity Incentive Plan ("2022 Plan") whereby the Company may grant up to 10,000,000 shares of the Company's voting common stock. Commencing on the first day of each fiscal year beginning January 1, 2023 and ending January 1, 2032, the available shares under the 2022 Plan are to be increased by a number of shares of voting common stock of the Company equal to the lesser of (a) 5% of the aggregate number of shares outstanding on the final day of the immediately preceding fiscal year and (b) such smaller number of shares as determined by a committee as defined in the 2022 Plan. As a result, effective January 1, 2026, the available shares under the 2022 Plan were increased for a new total of 23,129,145 shares.

In addition to the 2022 Plan, the Company has outstanding stock awards that were granted under various employee and director stock incentive plans. These previous plans were terminated prior to the adoption of the 2022 Plan.

***Stock Options***

Share-based compensation payments related to stock options are recognized in the condensed consolidated financial statements based on the grant date fair value using the Black-Scholes option pricing model. Share-based compensation expense is recognized over the related service or vesting period, net of actual forfeitures. Stock options generally vest over a period of up to five years and expire after ten years. No stock options were granted during the three months ended March 31, 2026. The following assumptions were used by the Company for determining the fair value of awards granted during the three months ended March 31, 2025:

---

| | |
|:---|:---|
| Weighted-average expected term (years) | 5.3 – 6.0 |
| Volatility (range) | 26.2% – 27.2% |
| Risk-free interest rate | 4.1% |
| Dividend yield | 0.00% |

---

The weighted-average grant-date fair value of options granted during the three months ended March 31, 2025 was $7.54. The total intrinsic value of options exercised during the three months ended March 31, 2026 and 2025 was $38.5 million and $0.6 million, respectively.

Share-based compensation expense is included in compensation and benefits expense in the condensed consolidated statements of operations. Stock-based compensation expense related to stock options was $4.5 million and $2.9 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, there were $18.3 million in total unrecognized compensation costs related to stock options. These costs are expected to be recognized over a weighted average period of 1.99 years.

***Restricted Stock***

The Company grants restricted stock awards to certain executives and other employees that vest upon the satisfaction of both time-based service and performance-based conditions. In certain cases, restricted stock is granted to certain employees that vest only upon the satisfaction of performance-based conditions such as the Company's consummation of a deemed liquidation event or an IPO.

The total fair value as of the respective vesting dates of restricted stock was $33.8 million and $4.7 million for the three months ended March 31, 2026 and 2025, respectively, including $15.5 million of fair value for 375,000 shares of restricted stock that vested during the three months ended March 31, 2026, for which vesting was triggered upon the IPO and was subject to the satisfaction of related post-IPO service conditions.

Total compensation expense related to the shares granted was $4.3 million and $6.5 million for the three months ended March 31, 2026 and 2025, respectively, including $2.0 million of compensation expense related to certain awards for which vesting was triggered upon the IPO, subject to subsequent time-based service conditions, during the three months ended March 31, 2026. The compensation expense related to restricted stock is included in employee compensation and benefits on the condensed consolidated statements of operations. Share-based compensation expense related to the restricted stock awards is measured at the grant date fair value of the Company's common stock. See Note 14 - Fair Value Measurement for details regarding the Company's common stock valuation prior to the IPO.

**18. SEGMENT REPORTING** 

The Company operates four reportable segments: Options, Equities, Futures, and International which is reflective of how the Company's CODM reviews and operates.

**Options** – The Options segment includes listed options on the stocks of individual corporations ("equity options") and options on exchange-traded products ("ETPs"), such as exchange-traded funds ("ETFs"), which are "multi-listed" options and listed on a non-exclusive basis. These options trade on MIAX Options, MIAX Pearl, MIAX Emerald and MIAX Sapphire, all U.S. national security exchanges. The Options segment also includes applicable market data revenue generated from OPRA Plan, the licensing of proprietary options market data, index licensing, and access services.

**Equities** – The Equities segment includes our business operations relating to listed U.S. equities and ETP transaction services that occur on MIAX Pearl. The Equities segment also includes applicable market data revenue generated from the CTA Plan, the UTP Plan, and the CQS Plan, as well as licensing of proprietary equities market data, routing services, and access services.

**Futures** – The Futures segment includes transaction services provided by MIAX Futures and Dorman Trading, which includes offerings for trading and clearing of futures products, the licensing of proprietary market data, as well as access services.

**International** – The International segment, which represents the Company's operations outside of U.S, includes listing services for capital market instruments such as equities, debt issues, funds, hedge funds, derivative warrants and insurance linked securities provided by BSX and listing of high yield bonds and private equity debt by TISE.

**Corporate and Other** – Corporate and Other includes certain other business ventures, corporate costs and operations including intersegment elimination as such items are not used to evaluate the operating performance of the above segments.

An operating segment is generally defined as a component of business for which discreet financial information is available and whose results are reviewed by the CODM. Operating segments are aggregated into reportable segments if certain criteria are met. The Company's CODM is its Chief Executive Officer who manages business operations, evaluates performance and allocates resources based on the segments' net revenues and operating income. Revenue and cost of revenue is recorded specifically in the segment in which they are earned or to which they relate. The Company directly allocates expenses to the operating segments when reasonably possible to do so. Management provides the non-operating (expenses) income and income (loss) before tax provision at the segment-level to the CODM on a recurring basis. However, the CODM does not consider non-operating (expense) income when evaluating performance of or allocating resources to the operating segment.

The following table presents certain selected financial information for the Company's reportable operating segments and Corporate and Other (in thousands):

**19. INCOME TAXES** 

The Company calculates the provision for income tax during interim periods based on the best estimate of the full year's tax rate as adjusted for discrete items, if any, that are taken into account in the relevant interim period. Each quarter, the Company updates its estimate of the annual effective tax rate and any change in the estimated rate is recorded on a cumulative basis.

Based on our analysis of all positive and negative evidence available as of March 31, 2026, having demonstrated sustained profitability which is objective and verifiable, and taking into account anticipated future earnings, we concluded it is more likely than not that our deferred tax assets will be realizable. Accordingly, we have recognized a tax benefit in the three months ended March 31, 2026 for the release of the entire deferred tax valuation allowance. The effective tax rate from continuing operations was (70.1)% and (1.0)% for the three months ended March 31, 2026 and 2025, respectively. The higher negative effective tax rate in 2026 compared to 2025 was mainly due to the release of the deferred tax valuation allowance in 2026. The effective tax rates differ from the U.S. statutory rate primarily due to movement in the valuation allowances in the corresponding periods.

**22. LEASES**

The Company has operating leases related to office space and data centers under non-cancellable operating leases that expire at various times through December 2034, some of which include options to renew or extend the lease for an additional 10 years. As of March 31, 2026, there are no leases with residual value guarantees or leases not yet commenced to which the Company is committed. The Company combines the lease and non-lease components of lease payments in determining right of use assets and related lease liabilities.

Leases with an initial term of twelve-months or less that do not include an option to purchase the underlying asset are not recorded on the condensed consolidated balance sheets and are expensed on a straight-line basis over the lease term. The lease expenses related to the short-term leases were immaterial for the three months ended March 31, 2026 and 2025. Lease expense related to office space amounted to $2.0 million and $1.6 million for the three months ended March 31, 2026 and 2025, respectively, and are recorded within occupancy costs in the condensed consolidated statements of operations. Lease expense related to the data centers amounted to $2.7 million and $2.5 million for the three months ended March 31, 2026 and 2025, respectively, and are recorded within information technology and communication costs in the condensed consolidated statements of operations.

**Overview**

***Our Company***

We are a technology-driven leader in building and operating regulated financial marketplaces across multiple asset classes and geographies.

We operate markets across a diverse number of asset classes including options, futures and cash equities and are developing a portfolio of new products. Our markets include: options through MIAX Options, MIAX Pearl, MIAX Emerald, and MIAX Sapphire; U.S. equities through MIAX Pearl Equities; U.S. futures and options on futures through MIAX Futures, and international listings through BSX and TISE. We also own Dorman Trading, an FCM. We also trade Hard Red Spring Wheat futures and options on MIAX Futures. Through MIAX Futures Clearing, we also offer clearing services for U.S. futures and options on futures. We also owned MIAXdx, a DCM, and a DCO prior to the disposition of MIAXdx in January 2026.

***MIAXdx Transaction***

On January 20, 2026, we completed the sale of 90% of the issued and outstanding equity in MIAXdx to a joint venture established by Robinhood Markets, Inc. in partnership with Susquehanna International Group. We retained 10% of the issued and outstanding equity of MIAXdx, now known as Rothera.

As of December 31, 2025, we determined that MIAXdx met the criteria to be classified as held for sale, and accordingly, its total assets of $41.0 million and total liabilities of $2.8 million were presented separately as assets held for sale and liabilities held for sale, respectively, in the consolidated balance sheet as of December 31, 2025.

The sale of MIAXdx resulted in a gain of $50.5 million, which was recognized upon closing in January 2026.

***TISE Acquisition***

On June 5, 2025, MIH, through MIH East Holdings, Limited completed the TISE Acquisition. Prior to the TISE Acquisition, MIH East owned 29.46% of the issued ordinary share capital in TISEG. The total cash consideration paid for the TISE Acquisition was approximately £51.5 million ($69.7 million).

***Initial Public Offering***

In August 2025, we raised $396.8 million in gross proceeds from our IPO of 17,250,000 shares of common stock, including the full exercise of the underwriters' option to purchase additional shares.

***2029 Senior Secured Term Loan***

In August 2024, we entered into a $100 million senior secured term loan maturing in August 2029, which bore interest at 12.90% per annum (the "2029 Senior Secured Term Loan"). In June 2025, we obtained an additional $40 million

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

incremental term loan on substantially similar terms. We also issued to the lenders warrants to purchase up to 2,277,338 and 1,518,226 shares of common stock with an exercise price equal to $7.15 and $8.55 per share, respectively. The warrants included a put right permitting the lenders to require us to redeem any unexercised portion at fair value, which terminated upon our IPO in August 2025. Prior to the IPO, the warrants were classified as a liability and remeasured at fair value at each reporting period, with changes in fair value recognized in non-operating income (expense) in the consolidated statements of operations. Upon completion of the IPO, the warrant liability was reclassified to equity.

In August 2025, we paid the entire outstanding balance of the term loan and incremental term loan for $178.4 million, inclusive of accrued interest and a prepayment premium. In December 2025, in connection with the our secondary offering, an aggregate of 3,690,079 warrants were exercised on a cashless basis, resulting in the issuance of 3,065,826 shares of our common stock. During the first quarter of 2026, the remainder of the warrants were exercised, resulting in no warrants outstanding as of March 31, 2026.

***Pyth Tokens Unlocking***

In 2021, BSX entered into agreements with Pyth to begin publishing limited derived equities market data for certain symbols from MIAX Pearl Equities on the Pyth Network, a decentralized financial market data distribution platform for aggregated data. In exchange, Pyth granted BSX 500 million Pyth tokens which were locked and restricted from trading with a four year unlocking schedule commencing on May 20, 2024. We also received an additional 0.8 million locked reward Pyth tokens, which will be unlocked at various times during 2025 through 2028. While the Pyth tokens are locked they are not in the control or possession of BSX, cannot be traded by BSX, and are held by another entity. The Pyth tokens unlock on the schedule based on the agreement under which they were issued, and do not require any further performance by BSX in order to receive the Pyth tokens as they unlock.

We received net proceeds of $16.2 million and $52.6 million in 2025 and 2024, respectively, from the sale of each of the 125 million unlocked Pyth tokens. The remaining 250 million locked tokens will be distributed to BSX by the Pyth Network at the time of unlocking and are expected to be unlocked at a rate of 125 million tokens each on May 20, 2026 and May 20, 2027. This right to receive Pyth tokens meets the definition of a derivative and is recognized at fair value at each reporting date recorded in derivative assets (current and noncurrent) in the condensed consolidated balance sheets with changes in fair value recognized in non-operating (expense) income in the condensed consolidated statements of operations. As of March 31, 2026, the fair value of derivative assets associated with the 250 million locked Pyth tokens amounted to $8.6 million.

**Our Business Model**

***Business Segments***

We report four business segments: Options, Equities, Futures, and International. Segment performance is primarily based on revenues less cost of revenues, operating income and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA"). We have aggregated all of our corporate costs and eliminations, as well as other business ventures, within Corporate and Other; however, operating expenses that relate to activities of a specific segment have been allocated to that segment.

Management allocates resources, assesses performance and manages our business according to these four business segments:

**Options**. The Options segment includes our business operations relating to listed options on the stocks of individual equity options and options on ETPs, such as ETFs, which are "multi-listed" options and listed on a non-exclusive basis. These options trade on MIAX Options, MIAX Pearl, MIAX Emerald and MIAX Sapphire, which are all U.S. national security exchanges. The Options segment also includes applicable market data revenue generated from the OPRA Plan, the sale of proprietary market data, index licensing and access services.

**Equities**. The Equities segment includes our business operations relating to listed U.S. equities and ETP transaction services that occur on MIAX Pearl. The Equities segment also includes applicable market data revenue generated from the CTA Plan, the UTP Plan, and the CQS Plan, as well as licensing of proprietary market data, routing services and access services.

**Futures***.* The Futures segment includes our business operations relating to futures transaction services provided by our futures exchange and clearing house, MIAX Futures. These services include offerings for trading and clearing of futures products, the licensing of proprietary market data, listings fees, as well as access services. Also included is Dorman Trading, a full-service FCM registered with the CFTC. MIAXdx, a futures exchange, clearing house, and swaps execution

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

facility registered with the CFTC was included within the Futures segment until it was sold by the Company in January 2026.

**International***.* The International segment includes listing services for capital market instruments such as equities, debt issues, funds, hedge funds, derivative warrants and insurance linked securities provided by BSX and listing of high yield bonds and private equity debt by TISE.

**Key Factors Driving Our Performance**

In broad terms, our business performance is impacted by several drivers, including macroeconomic events affecting the risk and return of financial assets, investor sentiment, the regulatory environment for capital markets, geopolitical events, tax policies, central bank policies and changing technology, particularly in the financial services industry. We believe our future revenues and net income will continue to be influenced by a number of trends, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• trading volumes in listed equity options, futures, equity securities and ETFs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to maintain or expand market share in listed equity options, listed futures, and listed equity securities and ETFs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to develop and successfully launch proprietary futures and options products based on licensed Bloomberg indexes, and to generate sufficient trading activity to support their long-term viability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the demand for and pricing structure of the U.S. Tape Plan market data distributed by the Securities Information Processors ("SIPs") and the market data distributed by OPRA which determine the pool size of the industry market data revenue we receive based on a known formula using trading and/or quoting activity, as required by NMS;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidation and expansion of our customers and competitors in the industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the demand for information about, or access to, our markets, which is dependent on the products we trade, our importance as a liquidity center and the quality and pricing of our data and access services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continuing pressure in transaction fee pricing due to intense competition and the proposed new ORF model and the impact on regulatory fee revenue;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inverted pricing, where liquidity payments exceed transaction revenues, implemented to attract volume in listed equity securities and ETFs and volumes on our proprietary products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ongoing costs, funding uncertainties, and regulatory and litigation developments related to historical, current and future funding of the implementation and operation of the CAT, including risks related to the collection of promissory notes issued to fund CAT;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory changes relating to market structure and increased capital requirements and those which affect certain types of instruments, transactions, pricing structures, capital market participants or reporting or compliance requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential introduction of new or competing financial products or services by competitors in the industry, including those enabled by new technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant structural, political and monetary issues as well as macroeconomic effects of global events, including developments in tariffs, changes in inflation, fluctuations in commodity prices, potential recession, and prevailing interest rate levels, and geopolitical developments such as regional conflicts or wars, which have resulted and may continue to result in an increased or subdued market volatility, changes in trading volumes, and greater market uncertainty.

**Key Components of Our Results of Operations**

***Revenues***

*Transaction and Clearing Fees*

Transaction fees represent fees we charge to our exchange member firms, as customers, for the performance obligation of executing a trade on our exchanges and comprise the majority of our revenues. These fees can be variable based on trade

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis in accordance with our published fee schedules. Transaction fees also include Dorman Trading's sales and brokerage commissions generated by customers' trading activity on options and futures. Transaction fees are recognized across all operating segments and are recorded as transactions occur on a trade-date basis. Clearing fees, which include settlement fees, are charged by us for transactions cleared by MIAX Futures, Dorman Trading and BSX. Clearing fees can be variable based on cleared volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded and billed on a monthly basis in accordance with our published fee schedules. Clearing fees are recognized in the Futures segment for MIAX Futures and Dorman Trading and in the International segment for BSX, and are recorded as transactions are cleared.

Tiered discounts are offered to customers based on the amount of trades that are executed on our exchanges. As these are volume driven, they reduce the transaction price and are recorded net in transaction fees. Liquidity payments paid for certain customer transactions are accounted for as consideration payable to a customer and are recorded separately as cost of revenues.

Transaction and clearing fees also result in regulatory fees. Regulatory fees include the ORF and Section 31 fees. ORF is in place to fund our regulatory oversight function of the exchange marketplace and is determined based on the number of customer contracts and cannot be used for non-regulatory purposes. Section 31 fees are transaction fees charged by the SEC to the exchanges. The Section 31 fees charged to customers are based on the fee set by the SEC per notional value of transactions executed on our securities markets and are calculated and billed monthly. Beginning on May 14, 2025, the rate was reduced from $27.80 per million for covered sales to a rate of $0.00 per million. This reduction was a temporary adjustment with the fee reverting to a new rate once legislation for fiscal year 2026 appropriation was enacted. On February 27, 2026, the SEC announced that starting on April 4, 2026, the new fee rates would be set at $20.60 per million for covered sales. The Section 31 fee collected by us is ultimately payable to the SEC, and therefore we record a corresponding cost of revenues.

*Access Fees*

Access fees include fees assessed for allowing customers, which include exchange member firms and non-member firms, to connect their networks to one of our exchanges for a specified period of time. Fees for these services are assessed to customers for the opportunity to trade as member firms, or in the case of non-member firms to provide these services to member firms, and use other related functions of the exchanges. Access fees are billed monthly in accordance with our published fee schedules and are recognized during the period the service is provided, which is generally one month. Access fees are recognized across all operating segments.

*Market Data Fees*

We charge market data fees for making market data available to customers either through direct subscriptions or through our participation in the U.S. Tape Plans. Market data revenue includes distributions from the U.S. Tape Plans, which is distributed based upon each individual exchange's market share of U.S. volume, trades, and/or quotes. Market data revenue also includes market data revenue earned from the sale of proprietary market data directly to the customer on a subscription or ad-hoc basis, or from third parties where the Company is the principal in the transaction. Market data revenue is recognized in the period the data is provided. U.S. Tape Plan market data is recognized in the Options and Equities segments. Proprietary market data fees are recognized across all segments.

*Other Revenue*

Other revenue primarily includes initial and annual listing fees from TISE, BSX, and MIAX Futures listings, member fines, office rental income, and interest income from MIAX Futures and Dorman Trading clearing operations.

*Concentration of Revenue*

The following tables summarize each customer's revenue concentration as a percentage of the Company's total revenues during the three months ended March 31, 2026 and 2025:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** |
| | **March 31,** | **March 31,** |
| | **2026** | **2025** |
| Customer 1 | 17% | 13% |
| Customer 2 | 16% | 18% |
| Customer 3 | 12% | 12% |

---

While the Company has historically had certain recurring customers, no customer is contractually or otherwise obligated to continue to use our services and therefore there is no assurance that recurring customers or revenues will continue in future periods.

***Cost of Revenues***

*Liquidity Payments*

Liquidity payments are directly correlated to the volume of securities traded on our markets. We record liquidity payments paid to market participants providing liquidity and/or order flow as cost of revenues and consider them to be a distinct service. In certain instances, including for new segments and proprietary products, liquidity payments exceed transaction fees resulting in inverted pricing. In our Equities segment, we have at times offered liquidity payments higher than transaction fees to attract order flow that might otherwise trade on other exchanges.

For certain new products in our Futures segment, we may waive certain transaction fees and provide liquidity payments to attract volumes from competing proprietary products offered on other exchanges. Additionally, in our Futures segment through Dorman Trading, we record liquidity payments to introducing brokers.

*Brokerage, Clearing and Exchange Fees*

Brokerage, clearing and exchange fees include fees incurred by Dorman Trading for clearing and settlement services paid to executing brokers, exchanges, clearing organizations and banks. There are also various rules that require U.S. options and equities trade executions occur at the National Best Bid/Offer ("NBBO") displayed by any exchange. Linkage order routing consists of the cost incurred to provide a service whereby our equities and options exchanges deliver orders to other execution venues when there is a potential for obtaining a better execution price or when instructed to directly route an order to another venue by the order provider. The service affords exchange order flow providers an opportunity to obtain the best available execution price and may also result in cost benefits to those clients. Such an offering improves our competitive position and provides an opportunity to attract orders which would otherwise bypass our exchanges. We utilize third-party brokers to facilitate such delivery. Additionally, within brokerage, clearing and exchange fees are costs incurred by MIAX Futures for futures trades executed on CME Globex. The expense for CME Globex ceased on June 30, 2025 when MIAX Futures migrated from the CME Globex platform and onto the MIAX Futures Onyx trading platform.

*Section 31 Fees*

Exchanges under the authority of the SEC (MIAX Options, MIAX Pearl, MIAX Emerald and MIAX Sapphire) are assessed fees pursuant to the Exchange Act designed to recover the costs to the U.S. government of supervision and regulation of securities markets and securities professionals. We treat these fees as a pass-through charge to customers executing eligible listed equities and listed equity options trades. Accordingly, we recognize the amount that we are charged under Section 31 as a cost of revenues and the corresponding amount that we charge our customers as transaction fees revenue. Since the regulatory transaction fees recorded in revenues are equal to the Section 31 fees recorded in cost of revenues, there is no impact on our operating income. Beginning on May 14, 2025, the rate was reduced from $27.80 per million for covered sales to a rate of $0.00 per million. This reduction was a temporary adjustment with the fee reverting to a new rate once legislation for fiscal year 2026 appropriation was enacted. On February 27, 2026, the SEC announced that starting on April 4, 2026, the new fee rates would be set at $20.60 per million for covered sales.

*Other Cost of Revenues*

Other cost of revenues include interest paid to customers generated from customer funds deposited with Dorman Trading to satisfy margin requirements held by third-party banks or on deposit with or pledged to clearing organizations or other FCMs, as well as the investment of customer funds in allowable securities, primarily U.S. Treasury obligations. MIAX Futures pays interest to clearing members from member funds deposited with MIAX Futures as clearinghouse performance bonds and guarantee funds. Also included with other cost of revenues are third-party trading platform fees which we charge to customers. These costs are incurred in our Futures segment by Dorman Trading.

***Operating Expenses***

*Compensation and Benefits*

Compensation and benefits represent our largest expense category and tend to be driven by our staffing requirements, financial performance and the general dynamics of the employment market. Stock-based compensation is a non-cash expense related to equity awards. Stock-based compensation can vary depending on the quantity and fair value of the award on the date of grant and the related service period. Certain outstanding equity awards vested or had vesting accelerated upon the Company's initial public offering.

*Information Technology and Communications*

Information technology and communications consists primarily of costs related to hosted data centers, maintenance and support of computer equipment and software, circuits supporting our wide area network and fees paid to information vendors for market data.

*Depreciation and Amortization*

Depreciation and amortization expense results from the depreciation of long-lived assets purchased, the amortization of purchased and internally developed software and the amortization of intangible assets.

*Occupancy*

Occupancy costs primarily consist of expenses related to owned and leased properties including rent, maintenance, utilities and real estate taxes.

*Professional Fees and Outside Services*

Professional fees and outside services consist primarily of consulting services, which include supplemental staff activities primarily related to legal, technology support, regulatory, audit and tax advisory services.

*Marketing and Business Development*

Marketing and business development includes marketing programs for new products, branding, promotions and corporate events.

*Acquisition-Related Costs*

Acquisition-related costs relate to the TISE Acquisition. The acquisition-related costs include fees for investment banking advisors, lawyers, accountants, tax advisors, and other external costs directly related to the acquisition.

*General, Administrative, and Other Expenses*

General, administrative, and other expenses represent all other costs necessary to support our operations including travel and entertainment, Board fees and commercial insurance.

***Non-Operating Income (Expense)***

Income and expenses incurred through activities outside of our core operations are considered non-operating and are classified as other income (expense). These activities primarily include the change in fair value of puttable common stock, change in fair value of puttable warrants issued with debt, interest expense related to outstanding debt facilities, interest earned on the investing of excess cash, gain on sale of business, investment gain/loss, and unrealized gains and losses on derivative assets (right to receive Pyth tokens).

**Results of Operations**

The following are summaries of changes in financial performance and include certain non-GAAP financial measures. Management uses these non-GAAP measures internally in conjunction with GAAP measures to help evaluate our performance and to help make financial and operational decisions. These non-GAAP financial measures assist management in comparing our performance on a consistent basis for purposes of business decision making by removing the impact of certain items management believes do not reflect our underlying operations.

We believe our presentation of these measures provides investors with greater transparency into financial measures used by management and is useful to investors for period-to-period comparisons of our ongoing operating performance.

These non-GAAP financial measures are not presented in accordance with, or as an alternative to, GAAP financial measures and may be calculated differently from non-GAAP measures used by other companies, which reduces their usefulness as comparative measures. We encourage analysts, investors and other interested parties to use these non-GAAP measures as supplemental information to the GAAP financial measures included herein, including our consolidated financial statements, to enhance their analysis and understanding of our performance and in making comparisons. See the footnotes below for definitions, additional information and reconciliations to the closest GAAP measure.

\*Not meaningful

(1)EBITDA is defined as income before interest expense and amortization of debt discount costs, interest income, income taxes and depreciation and amortization. Adjusted EBITDA is defined as EBITDA before share-based compensation, investment gain/loss, litigation costs, acquisition-related costs, change in fair value of puttable warrants issued with debt, change in fair value of puttable common stock, gain on sale of business, and unrealized gain/loss on derivative assets. EBITDA and adjusted EBITDA do not represent, and should not be considered as, alternatives to net income as determined in accordance with GAAP. We have presented EBITDA and adjusted EBITDA because we consider them important supplemental measures of our performance. In addition, we use adjusted EBITDA as a measure of operating performance for preparation of our forecasts. Other companies may calculate EBITDA and adjusted EBITDA differently than we do. EBITDA and adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP.

(2)EBITDA margin represents EBITDA divided by revenues less cost of revenues. Adjusted EBITDA margin represents adjusted EBITDA divided by revenues less cost of revenues.

(3)Adjusted earnings is defined as net income (loss) adjusted for share-based compensation, investment gain/loss, litigation costs, acquisition-related costs, change in fair value of puttable warrants issued with debt, change in fair value of puttable common stock, gain on sale of business, unrealized gain/loss on derivative assets, and non-GAAP tax adjustments. Adjusted earnings margin represents adjusted earnings divided by revenues less cost of revenues. Adjusted diluted earnings per share represents adjusted earnings divided by diluted weighted average shares outstanding used for adjusted diluted earnings per share (which includes the impact of anti-dilutive securities on a GAAP basis). Adjusted earnings does not represent, and should not be considered as, alternatives to net income as determined in accordance with GAAP. We have presented adjusted earnings because we consider this an important supplemental measure of our performance. In addition, we use adjusted earnings as a measure of operating performance for preparation of our forecasts. Other companies may calculate adjusted earnings differently than we do. Adjusted earnings has limitations as an analytical tool, and you should not consider it in isolation or as substitute for analysis of our results as reported under GAAP.

__________________

\*Percentage calculation is not meaningful.

(1)ADV is calculated as total contracts or shares for the period divided by total trading days for the period.

(2)RPC represents transaction and clearing fees less liquidity payments, brokerage, clearing and exchange fees and Section 31 fees (Net Transaction Fees), divided by total contracts traded during the period.

(3)Equities capture per one hundred shares refers to transaction and clearing fees less liquidity payments, brokerage, clearing and exchange fees, and Section 31 fees (Net Transaction Fees), divided by one-hundredth of total shares.

(4)Q1 2025 does not include TISE which was acquired in June 2025.

We closely monitor changes in ADV, market share and revenue per contract or equities capture as they directly impact our transaction related revenues. Transaction related revenues are a function of industry ADV, MIH market share, revenue per contract or equities capture, and number of trading days. We use changes in market ADV to identify broader industry trends, which can impact our revenues and profitability. We use changes in market share in areas such as evaluating our market position relative to our competitors and evaluating potential trading system functionality changes. Similarly, we use revenue per contract or equities capture changes in areas such as analysis of product or customer mix and to identify potential fee changes.

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

We believe the growth in Options Market ADV for the three months ended March 31, 2026 compared to the prior period of 18.8% is due to the continuation of several trends including heightened market volatility, growing retail participation, technological advances, increased sophistication of trading strategies, and the proliferation and adoption of new asset classes and financial products.

We believe the increase in U.S. Equities Market ADV for the three months ended March 31, 2026 compared to the prior period of 27.3% is due to similar trends as seen in the Options Market.

Our Options market share for the three months ended March 31, 2026 compared to the prior period increased to 17.3% from 16.0%. Our Options revenue per contract increased 3.8% for the three months ended March 31, 2026 compared to the prior period primarily due to changes in product mix.

Our U.S. Equities market share for the three months ended March 31, 2026 compared to the prior period decreased to 0.9% from 1.1%. Our Equities capture at $0.005 per 100 shares was positive for the three months ended March 31, 2026 compared to $(0.020) in the prior period where liquidity payments exceeded transaction revenues. The change was due to pricing changes.

Futures agricultural products ADV for the three months ended March 31, 2026 compared to the prior period decreased 39.9% due to lower volatility and participant migration timing to MIAX Futures Onyx. Futures agricultural revenue per contract decreased 18.3% primarily due to the introduction of a program in May 2025 to incentivize Hard Red Spring Wheat liquidity providers during and following the migration to the new MIAX Futures Onyx trading platform.

***Revenues***

Total revenues for the three months ended March 31, 2026 increased $42.6 million, or 13.0%, compared to the prior period primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $47.5 million increase in Options transaction and clearing fees excluding Section 31 revenue primarily as a result of an 18.8% increase in Options market contracts, an 8.1% increase in MIH Options market share, partially offset by a 5.5% decrease in transaction and clearing fees excluding Section 31 fees revenue per contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $8.7 million increase in Options access fees primarily due to increases in member connections, 2026 fee increases, and the expiration of certain MIAX Sapphire related fee waivers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $4.8 million increase in the International segment primarily due to the TISE Acquisition in June 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $3.3 million increase in Options market data fees primarily due to new product offerings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.8 million increase in Equities transaction and clearing fees excluding Section 31 revenue primarily as a result of a 29.5% increase in U.S Equities industry volume, a 4.7% increase in transaction and clearing fees excluding Section 31 fees revenue capture, partially offset by a 18.2% decrease in MIAX Pearl Equities market share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $23.5 million reduction in Section 31 fees as the rate was temporarily reduced from $27.80 per million for covered sales to $0.00 per million for covered sales beginning on May 14, 2025. On February 27, 2026, the SEC announced that starting on April 4, 2026, the new fee rates would be set at $20.60 per million for covered sales.

Transaction and clearing fees less liquidity payments, brokerage, clearing, exchange and Section 31 fees increased $20.2 million, or 36.5%, for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $18.0 million increase in Options net transaction fees due to a 18.8% increase in Options market contracts, an 8.1% increase in MIH Options market share, and a 3.8% increase in revenue per contract.

*Access Fees*

Access fees increased $9.3 million, or 38.5%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to increased member connections, 2026 fee increase, and the expiration of certain MIAX Sapphire related fee waivers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $2.7 million increase due to ad-hoc historical market data sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.1 million increase in proprietary market data primarily due to fee increases and new product offerings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.3 million decrease from lower MIAX Pearl Equities quote market share which decreased our share of fees from the U.S. Tape Plans.

*Other Revenue*

***Operating Expenses***

Total operating expenses for the three months ended March 31, 2026 compared to the same period in 2025 increased $13.0 million, or 18.7%, primarily due to increased compensation and benefits from higher headcount and timing on employer payroll taxes, higher information technology expenses, and increased legal expenses. These were partially offset by lower regulatory costs.

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

*Compensation and Benefits*

Compensation and benefits increased $6.6 million, or 17.5%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to:

*Information Technology and Communication Costs*

Information technology and communication costs increased $1.9 million, or 25.6%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.2 million increase in software and hardware maintenance costs primarily due to the buildout of the MIAX Sapphire exchange and the new MIAX Futures and BSX trading platforms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.5 million increase in other general IT expense including increased installations and configuration costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.2 million increase for data center costs primarily due to additional space needed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.1 million increase in market data expense.

*Depreciation and Amortization*

Depreciation and amortization increased $1.9 million, or 31.1% for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $3.0 million increase resulting from capital spending including the launch of the MIAX Sapphire trading floor, and the new MIAX Futures and BSX trading platforms, as well as increased trading system and business system capacity growth and new functionality.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.1 million decrease from certain assets being fully depreciated.

*Occupancy Costs*

Occupancy costs increased $0.8 million, or 32.5%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to a lease renewal, and additional space for the MIAX Sapphire floor.

*Professional Fees and Outside Services*

Professional fees and outside services costs increased $2.2 million, or 23.2%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.3 million increase in legal fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.2 million decrease in regulatory expenses primarily driven by lower CAT costs as invoicing is currently paused.

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

*Acquisition-Related Costs*

Acquisition-related costs include fees for professional services, and other external costs directly related to the acquisition. There were no acquisition-related costs for the three months ended March 31, 2026. For the three months ended March 31, 2025, acquisition-related costs of $0.7 million relate to the TISE Acquisition.

*General, Administrative, and Other*

General, administrative, and other expenses increased $0.1 million, or 1.0% for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.3 million decrease in travel and entertainment.

***Operating Income***

As a result of the items above, there was operating income of $46.0 million for the three months ended March 31, 2026, compared to operating income of $22.3 million for the same period in 2025.

***Change in Fair Value of Puttable Common Stock***

The change in fair value of puttable common stock of $(0.2) million for the three months ended March 31, 2025 represents the increase in fair value of outstanding common stock awarded to the participants of ERPs I and II. Prior to the IPO, these awards had an associated put right that could require the Company to repurchase a certain percentage of the fair market value of the award upon exercise. The fair market value of these awards was reflected in puttable common stock, net of current portion on the Company's consolidated balance sheets.

The right to put shares terminated upon completion of the Company's IPO in August 2025.

***Change in Fair Value of Puttable Warrants Issued with Debt***

The change in fair value of puttable warrants issued with debt of $0.6 million for the three months ended March 31, 2025 represents the decrease in fair value of the warrants issued in connection with the 2029 Senior Secured Term Loan. Prior to the IPO, the warrants included a put right for unexercised warrant under certain conditions. The initial fair value of the puttable warrants was accounted for as a debt discount and the fair value of the outstanding liability was reflected in puttable warrants issued with debt on the Company's consolidated balance sheets.

The right to put warrants terminated upon completion of the Company's IPO in August 2025.

***Interest Expense and Amortization of Debt Issuance Costs***

Interest expense and amortization of debt issuance costs was less than $0.1 million for the three months ended March 31, 2026, compared to $4.4 million in the same period in 2025. On August 18, 2025, the Company used a portion of the proceeds from the IPO to repay the entire outstanding balance of the 2029 Senior Secured Term Loan including the Incremental Term Loan in an aggregate principal amount of $140.0 million.

***Interest Income***

Interest income was $4.4 million for the three months ended March 31, 2026, an increase of $3.1 million or 238.7% compared to the same period in 2025, primarily due to a higher average cash balance from proceeds from the IPO and increased cash from operations.

***Unrealized Loss on Derivative Assets***

For the three months ended March 31, 2026, the unrealized loss of $2.5 million reflects the unrealized loss on the 250 million Pyth tokens that remain locked by the Pyth Network. For the three months ended March 31, 2025, the unrealized loss of $42.4 million represents the unrealized loss on 375 million Pyth tokens that remained locked by the Pyth Network. These tokens were recorded at fair market value during the second quarter of 2024 when an active market emerged for the tokens.

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

***Gain on Sale of Business***

On January 20, 2026, the Company completed the sale of 90% of the issued and outstanding equity in MIAXdx to a joint venture established by Robinhood Markets, Inc. in partnership with Susquehanna International Group. MIH has retained 10% of the issued and outstanding equity of MIAXdx, now known as Rothera. The sale of MIAXdx resulted in a gain of $50.5 million, which was recognized upon closing in January 2026. See Note 6 - "Investments" of the notes to condensed consolidated financial statements, for additional information.

***Other, Net***

For the three months ended March 31, 2026, other income, net of $1.7 million primarily represents an unrealized gain on marketable equity securities of $1.0 million, and dividend income of $0.3 million. For the three months ended March 31, 2025, other income, net of $1.7 million primarily represents an unrealized gain on available for sale marketable equity securities.

***Income (Loss) Before Income Tax Provision***

As a result of the above, income before income tax provision was $100.0 million for the three months ended March 31, 2026 compared to a loss before income tax provision of $21.2 million for the same period in 2025.

***Income Tax Provision***

Based on our analysis of all positive and negative evidence available as of March 31, 2026, having demonstrated sustained profitability which is objective and verifiable, and taking into account anticipated future earnings, we concluded it is more likely than not that our deferred tax assets will be realizable. Accordingly, we have recognized a non-recurring tax benefit in the three months ended March 31, 2026 for the full release of the deferred tax valuation allowance. The effective tax rate from continuing operations was (70.1)% and (1.0)% for the three months ended March 31, 2026 and 2025, respectively. The higher negative effective tax rate in 2026 compared to 2025 was mainly due to the release of the deferred tax valuation allowance in 2026.

***Net Income (Loss)***

As a result of the items above, there was net income for the three months ended March 31, 2026 of $170.2 million compared to a net loss of $21.4 million for the same period in 2025.

**Segment Operating Results**

We report results from our four segments: Options, Equities, Futures, and International. Segment performance is primarily based on revenues less cost of revenues, operating income (loss) and adjusted EBITDA. We have aggregated all corporate costs, as well as other business ventures, within the Corporate and Other as those activities should not be used to evaluate a segment's operating performance. All operating expenses that relate to activities of a specific segment have been allocated to that segment.

(2)Adjusted EBITDA margin represents adjusted EBITDA divided by revenues less cost of revenues.

Revenues less cost of revenues increased $30.0 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $18.0 million increase in Options transaction and clearing fees less liquidity payments, brokerage, clearing, exchange and Section 31 fees due to an 18.8% increase in Options market contracts, an 8.1% increase in MIH Options contracts, and an 3.8% increase in revenue per contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $8.7 million increase in access fees primarily due to increased member connections, 2026 fee increases, and the expiration of certain MIAX Sapphire related fee waivers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $3.3 million increase in market data primarily due to ad-hoc historical market data sales as well as fee increases and new product offerings.

For the three months ended March 31, 2026, operating expenses increased $7.8 million compared to the three months ended March 31, 2025 primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $4.4 million increase in compensation and benefits primarily driven by additional headcount, higher bonus, and higher employer payroll taxes primarily related to timing of incentive compensation payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.3 million increase in depreciation and amortization primarily due to the launch of MIAX Sapphire.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.3 million increase in litigation and other legal expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.0 million increase in information technology and communication costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.9 million decrease in regulatory fees primarily due to lower CAT costs as invoices are temporarily paused.

Revenues less cost of revenues increased $3.0 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025, primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $2.7 million increase in Equities transaction and clearing fees less liquidity payments, brokerage, clearing, exchange and Section 31 fees, primarily due to positive capture caused by pricing changes, as compared to negative pricing in the prior year as liquidity payments exceeded transaction revenues.

For the three months ended March 31, 2026 compared to the same period in 2025, operating expenses was relatively unchanged primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.7 million increase in compensation and benefits primarily driven by additional headcount, higher bonus, and higher employer payroll taxes primarily related to timing of incentive compensation payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.4 million decrease in depreciation costs due to end of life of certain assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.2 million decrease in regulatory fees primarily due to lower CAT costs as invoices are temporarily paused.

As a result of the items above, there was an operating loss of $1.0 million for the three months ended March 31, 2026 as compared to an operating loss of $4.0 million in the same period in the prior year. After adjusting for share-based compensation, adjusted EBITDA was $0.9 million as compared to a $1.7 million loss for the same period in the prior year.

(2)Adjusted EBITDA margin represents adjusted EBITDA divided by revenues less cost of revenues.

Revenues less cost of revenues decreased $1.3 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.5 million lower net transaction fees primarily due to decreased agricultural volume, and lower RPC, partially offset by lower CME Globex cost of revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.4 million lower listings fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.3 million lower interest income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.2 million decrease due to the sale of MIAXdx in January 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.1 million increase in other cost of revenues.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.2 million in increased access fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.2 million in increased market data fees.

For the three months ended March 31, 2026 compared to the same period in 2025, operating expenses was relatively unchanged primarily due to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $2.2 million decrease in total operating expenses due to the sale of MIAXdx.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.5 million increase in compensation and benefits excluding the impact of MIAXdx primarily driven by additional headcount, higher bonus, and higher employer payroll taxes primarily related to timing of incentive compensation payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.6 million increase in depreciation and amortization excluding the impact of MIAXdx primarily due to the buildout of the new MIAX Futures clearing and trading platform (MIAX Futures Onyx).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.2 million increase in information technology and communication costs excluding the impact of MIAXdx.

As a result of the items above, there was an operating loss of $12.5 million for the three months ended March 31, 2026 as compared to an operating loss of $11.3 million in the same period in the prior year. After adjusting for share-based compensation and investment gain, adjusted EBITDA was a loss of $8.6 million as compared to a $7.2 million loss for the same period in the prior year.

Revenues less cost of revenues increased $4.8 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025, primarily due to the impact of the June 2025 TISE Acquisition.

For the three months ended March 31, 2026, operating expenses increased $2.1 million compared to the three months ended March 31, 2025 primarily due to the impact of the June 2025 TISE Acquisition.

As a result of the items above, there was an operating income of $1.3 million for the three months ended March 31, 2026 as compared to an operating loss of $1.5 million in the same period in the prior year. After adjusting for unrealized losses on Pyth tokens, and share-based compensation, adjusted EBITDA was $2.0 million as compared to a $1.0 million loss for the same period in the prior year.

**Liquidity and Capital Resources**

Since our inception, we have financed operations primarily through issuances of common stock and warrants, borrowings under credit facilities and cash flow from operating activities.

On August 15, 2025, the Company completed its IPO, in which the Company issued 17,250,000 shares of common stock at a public offering price of $23.00 per share, which included 2,250,000 shares issued pursuant to the underwriters' option to purchase additional shares of the Company's common stock. The Company received $396.8 million in proceeds, before deducting underwriting discounts and commissions and offering expenses.

Based on our current level of operations, we believe our available cash, available borrowings and cash provided by operations will be adequate to meet our current liquidity needs for the next 12 months. In the near term, we expect that our cash from operations will meet our cash needs to fund our operations and capital expenditures. Our future capital requirements will depend on many factors, including but not limited to, our growth rate, headcount, sales and marketing activities, research and development efforts, capital expenditures, the introduction of new products and offerings, potential merger and acquisition activity, other strategic initiatives, volatility in the market or in certain securities and trading volume of our customers. We may be required to seek additional equity or debt financing in the future. In the event that we require additional financing, we may not be able to raise such financing on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued innovation, we may not be able to compete successfully, which would harm our business, results of operations and financial condition.

*Cash Provided by Operating Activities*

Cash provided by operating activities consisted of net income (loss) adjusted for certain non-cash items including depreciation and amortization and share-based compensation expense, as well as the effect of changes in operating assets and liabilities. Net operating assets and liabilities at any specific point in time are subject to many variables, including variability in user activity, the timing of cash receipts and payments and vendor payment terms.

For the three months ended March 31, 2026, cash provided by operating activities was $60.9 million, primarily due to a net income of $170.2 million, partially offset by $103.7 million of non-cash income and $5.7 million of cash outflows from changes in operating assets and liabilities. The primary drivers of the non-cash expenses during the period was a $71.0 million provision for deferred income taxes, and a $50.5 million gain on the sale of business.

For the three months ended March 31, 2025, cash provided by operating activities was $11.2 million, primarily due to a net loss of $21.4 million adjusted for the add-back of non-cash expenses of $57.3 million, partially offset by net outflows from changes in operating assets and liabilities of $24.7 million. The primary driver of the non-cash expense was the $42.4 million unrealized loss on derivative assets.

*Cash Provided by (Used in) Investing Activities*

For the three months ended March 31, 2026, cash provided by investing activities was $45.6 million, consisting of $59.8 million of proceeds from the sale of MIAXdx net of cash and cash equivalents partially offset by $11.7 million in purchases of property, equipment and leasehold improvements, and $2.6 million in capitalization of internally developed software.

For the three months ended March 31, 2025, cash used in investing activities was $8.1 million, consisting of $4.7 million in purchases of property, equipment and leasehold improvements and $3.5 million in capitalization of internally developed software

*Cash Provided by (Used in) Financing Activities*

For the three months ended March 31, 2026, cash provided by financing activities was $7.1 million, consisting primarily of $20.4 million in net proceeds from issuance of common stock, partially offset by $13.3 million from stock repurchases.

For the three months ended March 31, 2025, cash flows used in financing activities was $1.9 million, consisting primarily of $1.9 million for repurchases of common stock.

**Contractual Obligations**

As of March 31, 2026, we have outstanding unsecured promissory notes of $1.5 million, issued in 2023 and maturing in December 2026. Unpaid interest on these promissory notes (but not the principal) is convertible, at the option of the holder, into shares of the Company's common stock at a conversion price of $20.50 through the maturity date.

As of March 31, 2026, MIAX Futures and Dorman Trading maintain revolving lines of credit with certain banks.

**Recent Accounting Pronouncements**

For a discussion of recently adopted accounting pronouncements and recently issued accounting pronouncements not yet adopted, see Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report.

**Critical Accounting Policies and Estimates**

The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of the amounts of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. The Company bases its estimates on historical experience, observance of trends in particular areas, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Information from these sources form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources.

We have identified the policies below as critical to our business operations and the understanding of our results of operations. The impact of, and any associated risks related to, these policies on our business operations is discussed throughout "Management's Discussion and Analysis of Financial Condition and Results of Operations." For a detailed discussion on the application of these and other accounting policies, see Note 2 "Summary of Significant Accounting Policies" to our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report.

***Goodwill and Indefinite-Lived Intangible Assets and Related Impairment***

Goodwill represents the excess of the purchase price over the fair value assigned to the net assets, including identifiable intangible assets, of businesses acquired. Goodwill is allocated to our reporting units based on the assignment of the fair values of each reporting unit of the acquired company. Indefinite-lived intangible assets are comprised of exchange licenses. Goodwill and indefinite-lived intangible assets are not amortized but are tested for impairment at least annually or when indicators of impairment are identified.

We assess goodwill for impairment annually on October 1, or more frequently if events or circumstances indicate that the carrying amounts may not be fully recoverable. We first consider the option to assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If we conclude

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

that it is more likely than not that the fair value is less than the carrying amount, we then perform a one-step quantitative impairment test by comparing the reporting unit's fair value with its carrying value. An impairment loss is recognized for the amount by which the reporting unit's carrying value exceeds its fair value, up to the total amount of goodwill allocated to the reporting unit.

When a quantitative test is performed, we estimate the fair value of a reporting unit using a combination of an income approach and a market approach. The income approach uses a discounted cash flow methodology that involves significant judgment and projections of future performance. Assumptions about future revenues and future operating expenses, capital expenditures and changes in working capital are based on the annual operating plan and other business plans for each reporting unit. These plans take into consideration numerous factors, including historical experience, current and future operational plans, anticipated future economic conditions and growth expectations for the industries and end markets in which we participate.

We review our indefinite-lived intangible assets, for impairment whenever events or circumstances indicate that the carrying amount of an asset or asset group may not be fully recoverable. Similar to goodwill impairment testing, we test for impairment of indefinite-lived intangible assets during the fourth quarter of our fiscal year using an October 1 measurement date and may first perform a qualitative assessment. If we elect to perform or are required to perform a quantitative assessment, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to its carrying amount as of the impairment testing date. The determination of asset fair value is subject to significant judgment and utilizes valuation techniques including discounting estimated future cash flows. Our estimates of cash flows are based on past experiences adjusted for trends and future expectation, and can be significantly impacted by changes in our business or economic conditions. If the carrying value of the asset exceeds the estimated undiscounted future cash flows, an impairment loss is recognized for the difference between the estimated fair value and the carrying value.

***Income Taxes***

We record deferred taxes on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

We 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 upon the technical merits of the position. The tax benefit recognized in the consolidated financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Also, interest and penalties expense is recognized on the full amount of deferred benefits for uncertain tax positions. Our policy is to include interest and penalties related to unrecognized tax benefits in the income tax provision within the consolidated statements of operations.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

Market risk generally represents the risk of loss that may result from the potential change in the value of a financial instrument as a result of fluctuations in interest rates and market prices. Information relating to quantitative and qualitative disclosures about these market risks is described below.

**Interest Rate Risk**

As of March 31, 2026 and December 31, 2025, our cash and cash equivalents were $550.8 million and $433.6 million, respectively, of which $0.6 million and $0.6 million, respectively, were held in Bermuda, and $24.0 million and $21.7 million, respectively, were held in Guernsey. The remaining cash and cash equivalents are denominated in U.S. dollars and held primarily in interest-bearing accounts with financial institutions. Given the short-term nature and composition of these cash and cash equivalent balances, the Company does not believe that the results of operations or cash flows would be affected to any significant degree by a sudden change in market interest rates. As of March 31, 2026, we had $1.5 million in outstanding debt related to unsecured promissory notes. The outstanding debt bears interest at a fixed interest rate. Changes in interest rates will have no impact on the interest we pay on fixed rate obligations.

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

**Currency Exchange Risk**

We are exposed to foreign currency translation risk as revenues and expenses from our operations in Guernsey, through TISE, are denominated in British pound. For the three months ended March 31, 2026, the foreign currency impact of TISE on our condensed consolidated revenues and expenses was not material.

**Equity Risk**

Our investment in TISE with functional currency of British pound is exposed to volatility in currency exchange rate through translation of our net assets or equity to U.S. dollar. The translation of the non-U.S. dollar statement of financial condition into U.S. dollar, our reporting currency, results in a cumulative translation adjustment, which is recorded in accumulated other comprehensive income, net within stockholders' equity on our condensed consolidated balance sheets. As of March 31, 2026, our net equity investment in TISE amounted to $100.3 million and a 10% change in British pound foreign currency exchange rate would result in a $10.0 million impact on our consolidated equity.

**Credit Risk**

We are exposed to credit risk from third parties, including customers, counterparties and clearing agents. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons. We limit our exposure to credit risk by considering such risk when selecting the counterparties with which we make investments and execute agreements. The Company maintains cash with multiple regulated financial institutions and brokerage firms, and such balances may occasionally exceed depository insurance limits. Management monitors the financial condition of these institutions and believes that the likelihood of loss is remote.

We do not have counterparty credit risk with respect to trades matched on our options or equities exchanges in the U.S. With respect to equities, we deliver matched trades of our customers to the National Securities Clearing Corporation ("NSCC") without taking on counterparty risk for those trades. NSCC acts as a central counterparty on all equity transactions occurring on MIAX Pearl Equities and, as such, guarantees clearance and settlement of all of our matched equity trades. Similarly, with respect to U.S. options, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on MIAX Options, MIAX Pearl, MIAX Emerald and MIAX Sapphire and, as such, guarantees clearance and settlement of all of our matched options trades.

With respect to orders routed to other markets for execution on behalf of our customers, we are exposed to some counterparty credit risk in the case of failure to perform on the part of our routing brokers. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the condensed consolidated financial statements for these guarantees.

Credit difficulties or insolvency, or the perceived possibility of credit difficulties or insolvency, of one or more larger or more visible market participants could also result in market-wide credit difficulties or other market disruptions.

We also have credit risk related to fees that are billed in arrears to customers on a monthly basis. Our potential exposure to credit losses on these transactions is represented by the receivable balances in our condensed consolidated balance sheet. Our customers are financial institutions whose ability to satisfy their contractual obligations may be impacted by volatile securities markets.

On a regular basis, we review and evaluate changes in the status of our counterparties' creditworthiness. Credit losses such as those described above could adversely affect our condensed consolidated financial position and results of operations. Any such effects to date have been minimal.

Through MIAX Futures, the Company is exposed to further credit risk through our clearing operations. MIAX Futures holds material amounts of clearing participant collateral, both cash and non-cash deposits, which are held or invested primarily to provide security of capital while minimizing credit risk as well as liquidity and market risks. The following is a summary of the risks associated with these deposits and how these risks are mitigated:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Credit Risk — Credit risk to MIAX Futures comes primarily from two sources, which are the potential default or insolvency of a clearing participant or the insolvency of a settlement bank. Credit risk from clearing participants stems from the potential risk of non-performance by a participant to satisfy its obligations, financial or otherwise, to the clearing house. MIAX Futures attempts to mitigate credit risk posed by clearing participants through a variety of methods, such as marking open positions to market twice daily and requiring clearing participants to make security deposits and pledge margin based upon open positions held at MIAX Futures. Furthermore, MIAX Futures uses risk-based margin methodologies and models to estimate volatilities and determine appropriate

------

<u>[**Table of Contents**](#i336b3a0721ec4faa9944103b1396754e_7)</u>

margin requirements expected to cover exposures and reduce credit risk posted by market fluctuations. Although MIAX Futures clears limited physically delivered contracts, MIAX Futures may face large credit exposures on final settlement days should a participant fail to perform on its delivery obligations. To mitigate this risk, MIAX Futures closely monitors clearing participant exposures during the delivery period and applies product-specific heightened risk management standards through its rules. As to credit risk of settlement banks, MIAX Futures rules require that clearing participants maintain accounts at a settlement bank approved by MIAX Futures. In addition, MIAX Futures monitors approved settlement banks on an ongoing basis by performing financial reviews that evaluate, among other items, a bank's capital resources and liquidity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Liquidity Risk — Liquidity risk is the risk MIAX Futures may not be able to meet its payment obligations on time. To help mitigate this risk, MIAX Futures monitors its liquidity requirements closely and maintains funds and assets in a manner which attempts to minimize the risk of loss or delay in the access by the clearing house to such funds and assets. For example, liquidity risks posed by clearing participants are addressed through the collection of margin and the posting of security deposits. On a daily basis, MIAX Futures calculates performance bond requirements for all of its clearing participants' portfolios and requires that clearing participants post funds to the clearing house to cover its margin requirement. MIAX Futures also maintains multiple lines of credit that could be drawn upon to increase liquidity in the event of a default of a clearing participant. Lastly, MIAX Futures holds sufficient liquid resources to meet its financial obligations in the event of a default by the two clearing participants or their affiliates creating the largest combined loss to the clearing house in extreme but plausible market conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Market Risk — Market risk, including procyclicality, is another a source of risk faced by MIAX Futures. To help mitigate market risk, the clearing house establishes bond requirements designed to limit the likelihood of procyclical changes in such requirements and mitigate costly and disruptive adjustments to performance bond requirements in periods of high market volatility. Specifically, MIAX Futures rules provide that when calculating performance bond requirements, the clearing house will include measures designed to limit procyclicality that are equivalent to at least one of the options listed in Article 1, paragraph 2(b) of the European Commission's Implementing Decision 2016/377.

Through Dorman Trading, the Company is exposed to further regulatory and credit risks. Dorman Trading holds material amounts of customer funds. The following is a summary of the risks associated with these funds and how these risks are mitigated:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory Risk — Dorman Trading is registered as a futures commission merchant with the CFTC and NFA, and a member of various commodities and futures exchanges in the U.S. and abroad. Dorman Trading has a responsibility to meet margin calls at all exchanges on a daily basis, and even on an intra-day basis, if deemed necessary by relevant regulators or exchanges. Dorman Trading requires clients to make margin deposits the next business day, and requires their largest clients to make intra-day margin payments during periods of significant price movement. Margin required to be posted to the exchanges is a function of clients' net, or non-clearing FCM gross, open positions and required margin per contract. Dorman Trading is subject to minimum capital requirements under Section 4(f)(b) of the Commodity Exchange Act, Part 1.17 of the rules and regulations of the CFTC. These rules specify the minimum amount of capital that must be available to support clients' account balances and open trading positions, including the amount of assets that Dorman Trading must maintain in relatively liquid form. Further, the rules are designed to maintain general financial integrity and liquidity. The regulations discussed above limit funds available for dividends to us. As a result, we may be unable to access our operating subsidiaries' funds when we need them.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Client and Counterparty Credit and Liquidity Risk — Dorman Trading's operations expose us to credit risk of default of our clients and counterparties. The risk includes liquidity risk to the extent our clients or counterparties are unable to make timely payment of margin or other credit support. We are indirectly exposed to the financing and liquidity risks of our clients and counterparties, including the risks that our clients and counterparties may not be able to finance their operations. As a clearing broker, Dorman Trading acts on behalf of their clients for all trades consummated on exchanges. Dorman Trading must pay initial and variation margin to the exchanges, on a net basis, before receiving the required payments from our clients. Accordingly, Dorman Trading is responsible for clients' obligations with respect to these transactions, which exposes us to significant credit risk. Dorman Trading's clients are required to make any margin deposits the next business day, and requires their largest clients to make intra-day margin payments during periods of significant price movement. Dorman Trading's clients are obligated to maintain margin requirements at the level set by the respective exchanges, but we have the ability to increase margin requirements for clients based on their open positions, trading activity, or market conditions.

Additionally, Dorman Trading deposits its own funds and its customers' funds with banks and other financial institutions, including other FCMs under omnibus arrangements to effect daily cash settlements and, therefore, is exposed to the risks of settlement bank failures. Such failures could pose both credit risks and liquidity risks to Dorman Trading. In the event of the insolvency of one of these financial institutions, Dorman Trading might not be able to fully recover the assets it has deposited since, in certain cases, it will be among the institution's unsecured creditors. Dorman Trading may also make demand deposits with banks that are secured only to the value of FDIC insurance or other national deposit guarantee coverage, which is small, and therefore, the deposits may in significant part be lost in the event any of these banks or financial institutions become insolvent. As a result, Dorman Trading's business, financial condition and results of operations could be materially adversely affected by the loss of these funds.

**Item 4. Controls and Procedures**

***Evaluation of Disclosure Controls and Procedures***

Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. In connection with the preparation of this Quarterly Report, an evaluation was carried out by our management, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of March 31, 2026. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2026.

***Changes in Internal Control Over Financial Reporting***

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f)) that have occurred during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
