Cboe Clear Europe is a European equities central counterparty that provides post-trade services to stock exchanges, MTFs, over-the-counter (“OTC”) equities trades and an equity derivatives exchange. Cboe Clear Europe clears equities from nineteen European markets, as well as Depositary Receipts, ETFs, and equity-like instruments. In addition, Cboe Clear Europe clears equity derivatives in twelve European markets, including on index futures, index options, and single stock options.

In November 2024, Cboe Clear Europe received regulatory approval to offer access to its market participants to engage in SFT clearing. Cboe Clear Europe introduced a service for European SFT in cash equities and ETFs, which includes central clearing, settlement, and post-trade lifecycle management. This service aims to enhance the current bilateral SFT process between securities lenders and borrowers into a centrally cleared model, with Cboe Clear Europe acting as the counterparty to both sides of each SFT. In March 2025, the first SFT was processed on the Cboe Clear Europe platform.

Cboe Clear Europe only assumes the guarantor role if it has an equal and offsetting claim against a clearing member. Cboe Clear Europe, with respect to SFT services, utilizes The Bank of New York Mellon Corporation and J.P. Morgan as Tri-Party Collateral Agents for non-cash collateral, central, and correspondent banks for the exchange of cash collateral, while Pirum serves as the transmitter of transactions and post-trade lifecycle events on behalf of our mutual clients. For the period ended December 31, 2025, there have been no events of default for which a liability is required to be recognized in accordance with GAAP.

Margin deposits, which are predominantly in the form of cash and cash equivalents, are deposits made by each clearing member to Cboe Clear Europe to cover the credit risk of its failure to fulfill its obligations in the trade. Cboe Clear Europe maintains and manages all cash deposits related to margin deposits. Substantially all risks and rewards of cash and cash equivalents margin deposit ownership, including net interest income, belong to Cboe Clear Europe and are recorded in cash and spot markets on the consolidated statements of income. In the event of a default, Cboe Clear Europe can access the defaulting participant’s margin deposits to cover the defaulting participant’s losses. For more information, see “Default and Liquidity Waterfalls” below.

The clearing fund mutualizes the risk of default among all clearing members. Depending on their membership, clearing members contribute to the cash-equity and/or derivatives segment of the clearing fund. Although the entire clearing fund is available to cover potential losses in the event that the margin deposits and the clearing fund deposits of a defaulting clearing member are inadequate to fulfill that clearing member’s outstanding financial obligations, the clearing fund first uses the product class segment of the Clearing Fund in which the defaulting participants were active (see “Default and Liquidity Waterfalls” below). In the event of a default, Cboe Clear Europe is generally required to liquidate the defaulting clearing member’s open positions. To the extent that the positions remain open, Cboe Clear Europe is required to assume the defaulting clearing member’s obligations related to the open positions. Clearing members are required to make contributions to the clearing fund that are proportional to their risk exposure in the form of cash or non-cash contributions, which generally consist of highly liquid securities.

For the cash equity business line, Cboe Clear Europe has entered interoperable arrangements with two other central counterparties (“CCPs”). Under these arrangements, margin is pledged to and from interoperable CCPs. The interoperability fund consists of collateral provided by clearing members that is pledged by Cboe Clear Europe to the other interoperable CCPs, to cover margin calls Cboe Clear Europe receives from such interoperable CCPs.

Cboe Clear Europe is able to invest the cash collateral received in the form of interoperability fund deposits from clearing members in certain investments, typically securities issued by pre-approved sovereign issuers and reverse repurchase agreements with overnight maturities. When investments are made in accordance with Cboe Clear Europe’s investment policy, Cboe Clear Europe receives the amount of investment earnings and pays clearing members those earnings minus a set basis point cost of collateral. As Cboe Clear Europe is able to direct the investment of the cash interoperability fund deposits received from the clearing members within the program parameters and receives an economic benefit from those investments; these amounts are included in the margin deposits, clearing funds, and interoperability funds captions in the consolidated balance sheets and the related interest income and expense is recorded in other revenue and other cost of revenue, respectively, on the consolidated statements of income.

The default waterfall is the priority order in which the capital resources are expected to be utilized in the event of a default where the defaulting clearing member’s collateral would not be sufficient to cover the cost to liquidate its portfolio. If a

•Cboe Clear Europe's dedicated own resources: The Cboe Clear Europe default waterfall first utilizes its dedicated own resources in two forms and totaling 35%-50% of Cboe Clear Europe capital requirements; the ‘first skin in the game’, equal to 25% of Cboe Clear Europe capital requirements before the use of clearing fund contributions described below and the ‘second skin in the game’, an amount between 10-25% of capital requirements as discussed in Note 18 ("Regulatory Capital").

•Clearing fund: Second, the Cboe Clear Europe default waterfall utilizes traditional CCP risk mutualization, in the event that default losses fully exhaust Cboe Clear Europe’s dedicated own resources amount, whereby contributions applicable to a particular product class are applied first to any loss attributable to that product class.

•Pro rata contributions: Third, if the default losses caused cannot be covered by the first two layers, the non-defaulting clearing members shall on demand make additional payments to Cboe Clear Europe on a pro rata basis in proportion to the amount of their clearing fund contributions to cover any such remaining losses, which is limited to an amount equal to twice their clearing fund contribution as established under Cboe Clear Europe’s rules and regulations. In this scenario, contributions applicable to a particular product class are first applied to any losses attributable to that product class.

In addition to the default waterfall, the liquidity waterfall is the priority order in which the liquidity resources are expected to be utilized for Cboe Clear Europe’s ordinary course business operations and in situations when additional liquidity resources and liquidity measures may be activated in case of a potential liquidity shortfall. Liquidity, intraday or overnight, is mainly required for securities settlement. In ordinary course business circumstances, liquidity resources include the collateral directly deposited with Cboe Clear Europe, FX swap arrangements, and reverse repurchase agreements, as well as the use of the Facility.
