Item 1A. Risk Factors.

Except as set forth below, there have been no material updates during the period covered by this Form 10-Q to the Risk Factors as set forth in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 and in Item 1A. of our Form 10-Q for the three months ended March 31, 2025 and in Item 1A of our Form 10-Q for the three months ended June 30, 2025. These risks and uncertainties, however, are not the only risks and uncertainties that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also significantly impact us. Any risks and uncertainties may materially and adversely affect our business, financial condition or results of operations, liquidity and cash flows.

If we fail to attract or retain highly skilled management and other employees our business may be harmed.

Our success largely depends on the skills, experience and continued efforts of management and other key personnel. As a result, to be successful, we must retain and motivate executives and other key employees. Within the past year, the composition of our executive officers has substantially changed. We have a new Chief Executive Officer who started on May 7, 2025 and who assumed the role of President on August 2, 2025 and a new EVP, Global Head of Derivatives who started on October 1, 2025, in addition to other new members of our senior management team. Filling the roles and responsibilities of departing executive officers and employees may require us to devote time and resources to identifying, hiring and

integrating replacements for the departed executives and employees that could otherwise be used to pursue business opportunities and it is important to our success that these key personnel quickly adapt to and excel in their new roles. Our failure to successfully fill these roles and retain our key personnel could have a material adverse effect on our overall business, financial condition, and operating results.

There is substantial competition for qualified and capable personnel, particularly in the technology space, which may make it difficult for us to retain and recruit qualified employees in sufficient numbers. We have previously faced and may in the future face increased challenges in retaining and attracting qualified employees, including as we implement a return to office plan. Further, potential negative perceptions of our human capital management related programs, including whether due to perceived over- or under-pursuit of such programs, may result in increased challenges in retaining or attracting qualified employees, as well as potential litigation or other adverse impacts. If we fail to retain our current employees, it would be difficult and costly to identify, recruit and train replacements needed to continue to conduct and expand our business. In particular, failure to retain and attract qualified technology personnel could result in systems failures. Consequently, our reputation may be harmed, we may incur additional costs and our profitability could decline. There can be no assurance that we will be able to retain and motivate our employees in the same manner as we have historically done.

Additionally, effective succession planning is important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving our management team and key employees could hinder our strategic planning and execution.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Share repurchase program

In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and subsequently approved additional authorizations for a total authorization of $2.3 billion. The program permits the Company to purchase shares, through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation. The Company did not repurchase shares under the Company's share repurchase program during the three months ended September 30, 2025. As of September 30, 2025, the Company had $614.5 million of availability remaining under its existing share repurchase authorizations.

Purchase of common stock from employees

The table below reflects the acquisition of common stock by the Company in the three months ended September 30, 2025 that were not part of the publicly announced share repurchase authorization.
