Good morning. Thank you for joining us today to discuss our third quarter results. Our performance this quarter underscores how Cboe is operating from a position of strength, a result of our world-class products, platforms and people. We're building on that momentum and sharpening our strategic focus designed to unlock even greater value and opportunities for growth. Following the conclusion of a rigorous review of our businesses, we will initiate a sales process for our Cboe Australia and Cboe Canada businesses. We will discontinue our U.S. and European Corporate Listings efforts, and we will reduce our costs related to our U.S. and European ETP Listings businesses, Cboe Europe Derivatives Exchange and several of our smaller Risk and Market Analytics businesses. This strategic realignment ensures Cboe is well positioned in a dynamic and evolving market and strengthens our long-term vision to be a global derivatives leader. These changes will be accretive to earnings, and Jill will discuss in her prepared remarks how these actions strengthen our financial position and unlock new growth opportunities. I'd like to express our deep appreciation to all our team members for their dedication and hard work in supporting each of these businesses. While our Australian and Canadian equities businesses are performing well, we've determined that they fall outside of our core focus and strategy. We are grateful to our regulators in Australia and Canada for the support and collaboration they have shown us, and we will work closely with them to ensure a smooth transition for all of our key stakeholders. With this renewed focus, we are directing greater attention to our core businesses, which are operating from a position of strength. We see tremendous opportunities across index and multi-list options, Futures, U.S. And European Equities and FX, inclusive of Data Vantage. Leveraging these core areas of strength for Cboe and the strong secular growth trends supporting them, we believe we are well positioned to fully capture their growth and earnings potential as we strengthen our competitive positioning. Turning now to the third quarter. Cboe grew net revenue 14% year-over-year to a record $605.5 million and adjusted diluted EPS increased a robust 20% to a record $2.67. These results were again driven by strong volumes in both our multi-list and proprietary index option products, solid new sales growth in our Cboe Data Vantage business, robust industry volumes in our Cash and Spot markets and continued strong expense discipline. Most importantly, our performance once again underscored the durability of our net revenue generation with strength evident across nearly every segment of our business. In fact, in the third quarter, all 3 of our revenue categories: Derivatives Markets, Cash and Spot Markets and Data Vantage posted double-digit net revenue growth. As we head into the final months of the year, we look forward to building on those broad-based trends. Taking a closer look at the third quarter trends by category, our Derivatives franchise delivered another record quarter with net revenue increasing 15% year-over-year. In our multi-list options business, net transaction and clearing fees revenue was up a solid 14% given higher industry volumes and positive market share trends. While the multi-list option space remains highly competitive, Cboe is well positioned to benefit from strong secular trends, having taken meaningful steps to deepen our talent pool in the options space, while actively pursuing thoughtful regulatory reforms that support both the industry and investors. On the index options side, net transaction and clearing fees revenue was up a strong 19% as our proprietary SPX options complex set new records, powered by robust growth in 0DTE options trading. SPX 0DTE average daily volume surged 62% year-over-year, while overall SPX ADV increased 26% to a record 3.9 million contracts. 0DTE options made up over 61% of SPX volumes, up from a 48% share a year ago. We saw a similar dynamic in Mini-SPX options, where 0DTE, ADV more than doubled over the past year and drove an impressive 66% increase in total ADV during the quarter. 0DTE options now make up roughly half of Mini-SPX volume, up from 35% a year ago. In our proprietary options business, it's noteworthy that 9 of the 10 highest average daily volume months occurred in 2025, with September ranking as the third highest month on record only behind March and October month-to-date activity. In fact, our largest SPX day on record occurred on October 10 with 6.4 million SPX contracts traded and a record 33.2 million total options contracts traded across our index and multi-list products. It's also worth noting that growth in our 0DTE options franchise reflects not only wider adoption and broader access, but it's also a result of Cboe's distinct advantages in product innovation, contract design and market structure. We look forward to leaning into these advantages with our new [ MAG 10 ] index options and futures launch subject to regulatory approval, giving investors a simpler way to gain exposure to the AI and tech theme and a more precise way to manage risk using cash-settled European-style options. While SPX volumes in the third quarter were robust, our VIX products faced a more stable macro backdrop and lower realized volatility. The continued growth in our index options despite the lower activity in our VIX complex highlights the strength and versatility of Cboe's comprehensive volatility toolkit. Looking ahead, we remain positive on the outlook for our core derivatives business. With trade tensions, a government shutdown and more uncertain economic outlook, we see investors continuing to utilize options to manage risk. Secular trends of increasing retail participation and international expansion should provide further tailwinds. We continue to onboard more international brokers as global customers seek exposure to U.S. financial markets. Moving to Cash and Spot Markets. Net revenue was up a strong 14% as our European cash equities business continued to drive robust performance for the category, led by another quarter of strength in our European transaction businesses, the Europe and Asia Pacific segment delivered the strongest year-over-year net revenue percentage growth of any Cboe segment for the fifth quarter in a row, achieving an impressive 24% increase. This was driven by a 35% year-over-year growth in net transaction and clearing fees resulting from strong industry volumes, solid market share gains and a higher net capture. Global FX also made another solid contribution, growing net revenue 13% year-over-year in Q3. Over a longer time horizon, FX has delivered quarterly year-over-year net revenue growth in 17 of the last 18 quarters, speaking to the durability of this segment's revenue generation. Turning to Data Vantage. Net revenue increased by 12% on a year-over-year basis, reflecting continued momentum across our platform. Notably, nearly 90% of the growth across our market data and access businesses was driven by new unit and new sales as opposed to pricing. This growth speaks to the sizable demand for Cboe's Data and Access products, including our newer offerings, Dedicated Cores and Timestamping. Now I'll turn the call over to Jill to walk through the details of our financials and guidance for the quarter.
