Previous wording

Because the majority of our assets are short-term in nature, they are not significantly affected by inflation. However, the rate of inflation impacts our expenses, such as employee compensation, technology and communications expenses, which may not be readily recoverable in the prices of our services. Interest rates have remained higher since 2023 due to a period of increased inflation. To the extent interest rates remain high or inflation has other adverse effects on the securities markets or the economy, our financial position and results of operations may be adversely affected.

Previous wording

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law in the United States. The OBBBA made significant changes to existing U.S. federal and international tax provisions. The most impactful provisions to our business include the immediate expensing of domestic U.S. research. The OBBBA may have various impacts which are complicated by their different effective dates and many elections available in the OBBBA, as well as uncertainties around U.S. states’ reactions to these federal tax law changes. We are currently evaluating the impact of these provisions on our overall tax positions, including their effect on our current and deferred tax assets and liabilities, effective tax rate and cash tax obligations. The OBBBA does not impact our financial statements for the three and six month periods ended June 30, 2025.

Previous wording

There has been increased demand for portfolio trading workflows over the last few years, which has resulted in heightened competition among trading platforms to enhance their portfolio trading offerings and expand them across different geographies and products. Clients have been using portfolio trading workflows in lieu of more established trading protocols designed to generate price competition on individual bonds. Our dealer clients have also increased their usage of matching sessions offered by competing platforms in recent periods. To the extent that our clients increase their use of portfolio trading and matching session protocols offered by other platforms, our market share in those products could decrease. Due to the large size of the trades and the concentration of activity at the end of the month, portfolio trading can drive significant swings in trading volumes and estimated market share.

Furthermore, portfolio trading is generally provided under a lower-fee structure than other protocols and the growth of portfolio trading on our platform will likely have a negative impact on our average credit variable transaction fee per million.

Previous wording

Our business is subject to extensive regulations in the United States and internationally, which may expose us to significant regulatory risk and cause us to incur additional expense. The existing legal framework that governs the financial markets is periodically reviewed and amended, resulting in the enactment and enforcement of new laws and regulations that apply to our business. The SEC recently adopted final rules regarding the central clearing of certain secondary market transactions involving U.S. Treasury securities, which are currently set to become effective for certain cash market transactions on December 31, 2026. Once effective, this central clearing mandate will impact certain of our participants who do not centrally clear such trades today, and some of our investor clients have expressed concerns about using platforms that will require the clearing of any resultant trades executed on such platforms. While we expect this change will increase our own platform efficiency, it is still unknown at this time the full impact of this change, and what effect it will have, whether positive or negative, on our industry, our clients or us. In addition, following the change in U.S. presidential administrations in January 2025, the SEC withdrew multiple rule proposals, including those relating to the expansion of Regulation ATS and Regulation SCI. It remains unknown to what extent new legislation will be passed into law or whether other pending or new regulatory proposals will be adopted, abandoned or modified, or what effect such passage, adoption, abandonment or modification will have, whether positive or negative, on our industry, our clients or us.

Previous wording

We must continue to enhance and improve our electronic trading platforms. The markets in which we compete are characterized by increasingly complex protocols, systems, technology and infrastructure requirements that require us to devote substantial resources to modify and adapt our services. Our future success will depend on our ability to enhance our existing products and services, develop and/or license new products and technologies that address the increasingly sophisticated and varied needs of our existing and prospective broker-dealer and institutional investor clients and respond to technological advances and emerging industry and regulatory standards and practices, including cloud and AI technologies, on a cost-effective and timely basis. For example, in the first half of 2025, we continued our roll-out of Targeted RFQ, which highlights our AI-driven dealer selection tool, a machine learning model that predicts which counterparties are most likely to provide competitive pricing for high-touch workflows. We have also recently expanded our global Mid-X offering, a sessions-based mid-point matching tool for broker-dealers, to emerging market bonds. In addition, as the overall share of electronic trading grows in global credit products, we are experiencing continued demand for, and growth in, our automated and algorithmic trading solutions. We also support a large and growing base of dealer market making algorithms. We plan to continue to focus on technology infrastructure and automation initiatives to support more efficient trade execution by our clients.

Previous wording

In 2023, 2024 and 2025, the PSUs were granted to the executive officers and certain senior managers. Each PSU is earned or forfeited based on our level of achievement of certain predetermined metrics, including pre-tax adjusted operating margin, U.S. credit market share and revenue growth excluding U.S. credit. The vested share payout ranges from zero to 200% of the PSU target. The number of PSUs that vest, if any, is determined by the level of achievement of the performance metrics during the three-year performance periods, as certified by the Compensation and Talent Committee following the conclusion of the performance period. In addition, participants must provide continued service through the vesting date, subject to death, disability and qualified retirement exceptions, as applicable. Compensation expense for the PSUs is measured using the fair value of our stock at the grant date and estimates of future performance and actual share payouts. Each period, we make estimates of the current expected share payouts and adjust the life-to-date compensation expense recognized since the grant date. As of June 30, 2025, a 10.0% change in the expected final share payouts would increase or decrease the life-to-date compensation expense by $1.4 million. The estimated final share payouts for the 2022 and 2023 awards as of June 30, 2025 decreased 23.2% compared to December 31, 2024. See Note 9 for a discussion of the Company’s stock-based compensation expense.
