Thanks, John, and welcome to MIAX. We're excited to have you on board as our new Head of Investor Relations, taking over for Andy Nybo, who will turn his focus back to Corporate Communications. Thank you all for your interest in MIAX. What an extraordinary year 2025 has been, as we've achieved significant strategic milestones while delivering outstanding financial performance across our business. Today, I will provide high-level fourth quarter and full year results, update you on our business segments and discuss key strategic developments. Then Lance will walk through our financial highlights and our 2026 guidance. For the fourth quarter, total net revenue grew 52% year-over-year to $125 million. Adjusted EBITDA more than doubled year-over-year to $62 million, and adjusted EBITDA margin improved by 1,400 basis points to 50%. Q4 adjusted diluted EPS was $0.52. For the full year 2025, total net revenue grew 56% year-over-year to $431 million, and adjusted EBITDA more than doubled to $199 million. Full year adjusted EBITDA margin was 46%, reflecting 1,600 basis points of year-over-year improvement, while adjusted diluted EPS was $1.82. These impressive results reflect our ability to capitalize on elevated market volatility and drive continued volume and market share gains across our core business lines. Our market share in multi-listed options grew to a record 18.2% in the fourth quarter, up from 15.9% in the prior year period. This represents average daily volume of 11.1 million contracts, a 46% year-over-year increase that far outpaced industry ADV growth of approximately 28.4%. We have significantly increased our market share over the past few years and see additional opportunities for further expansion. And we'll continue to balance market share growth with healthy RPC levels. 2025 also brought several transformational developments for MIAX. Following on our successful IPO, we completed a secondary public offering in December with the closing of a public offering of 7.8 million shares of common stock, which consisted entirely of secondary shares. While MIAX did not sell shares or receive proceeds from this offering, it represents another milestone in our evolution as a public company and enhances our liquidity. In late '25, we announced the strategic sale of 90% of MIAX Derivatives Exchange or MIAXdx to Robinhood Markets in partnership with Susquehanna International Group while retaining a 10% equity stake. This transaction, which closed in January of 2026, provides MIAX with expedited access to the growing prediction markets through our retained equity position while also enabling us to maintain focus on our core product offerings. The strategic alignment with Robinhood and Susquehanna closely aligns with our approach of partnering with industry leaders to offer innovative trading products, and we're excited about the long-term value potential that our equity stake creates for MIAX's shareholders. Our MIAX Sapphire options trading floor in Miami that we launched in the third quarter continues to perform in line with our expectations and demonstrates the continued value of floor-based trading in today's hybrid market structure. We continue to build out new and innovative functionality to support the needs of our floor broker community and their customers, and we intend to roll out a number of additional enhancements in the first half of 2026. Miami's emergence as Wall Street South continues to accelerate, and we're proud to be at the center of this transformation as we look to scale our market share over time. Reflecting back on other notable accomplishments in 2025. The acquisition of TISE enables us to expand our international footprint, the launch of MIAX Futures Onyx and the completion of the new MIAX Futures clearing infrastructure allow us to provide the industry with a high-performance proprietary trading and clearing platform with state-of-the-art risk management capabilities. We remain very excited about our Bloomberg Index Futures products and plan to launch B100 and B500 Futures in the second quarter of 2026. While we previously communicated a February launch date, we recently made the decision to reschedule it to ensure we have the same reliability and performance profile on our futures platform that we pioneered in options markets. Importantly, we want to ensure the full ecosystem of participants are, in fact, connected to the new exchange on day 1. We will be introducing retail size contracts first to meet retail broker demand for access to products with low trading fees. We are also focused on offering products to meet emerging retail investor demand that allow them to hedge and efficiently manage exposure to equity markets. We maintain strong conviction in the strategic importance of these products to MIAX's long-term growth trajectory. Taking a broader look at several of our business segments. The options market environment in 2025 was exceptionally favorable for MIAX. Industry volatility remained elevated throughout the year, driven by a complex web of factors. While many businesses are volatility adverse, for MIAX, volatility creates increased demand for risk management tools and our technology infrastructure has proven its resilience during these high-volume periods. We expect elevated volatility throughout 2026, driven by geopolitics, domestic policy and political dynamics, tariff impacts and the evolving AI investment cycle. We're particularly excited about the rapid growth in new Monday and Wednesday short-term expirations in single stocks. This market segment has become increasingly important to retail and institutional participants alike. And our technology advantage with industry-leading throughput, low latency and deterministic performance positions us exceptionally well to capture this growing opportunity. We listed new Monday and Wednesday short-term options in 9 actively traded options classes, which we expect will contribute to both industry and our volume growth in 2026. Furthermore, we are positioned to benefit from an improving IPO pipeline and continued growth in structured products that use options as part of their strategies. Together, these should create additional trading opportunities and volume growth across our platforms. These trends, combined with our technology advantages, position us well to capitalize on the evolving options landscape. Turning to equities. Our equities business continues to evolve as our U.S. equity market presence creates strategic positioning to capture opportunities across market data and related asset classes. We have implemented an improved rate structure and reached breakeven adjusted EBITDA in the fourth quarter, demonstrating our commitment to operational efficiency. Our international operations continue to demonstrate their strategic value with the annuity value of this business becoming increasingly evident throughout 2025. We are actively working to maximize operational and revenue synergies across our TISE and BSX businesses, reflecting our ongoing commitment to optimizing our international footprint. As we look ahead, we remain focused on our 4 key competitive pillars: our differentiated technology, our broad range of regulatory licenses across multiple jurisdictions, our diverse and expanding product range and most importantly, our deep relationships with customers that allow us to develop the technology, services and products that support their evolving strategies. We are particularly optimistic about the current regulatory landscape, which creates exciting opportunities for us to expand into new products and services. On the operational front, we see opportunity to expand our market share on the MIAX Sapphire trading floor as we continue to enhance functionality to support demands from floor participants. We're experiencing strong growth in options products across our exchanges, driven by increased activity in short-term weekly options, the improving IPO pipeline and structured products and ETFs, all of which we expect to support sustained volume growth across the industry and on our exchanges. Perhaps most importantly, our collaboration and relationships with our members and industry participants remain strong and continue to be drivers of volume growth. These strategic relationships position us well to capitalize on market opportunities and continue delivering value to our customers as we execute on our strategic vision. Now I will turn the call over to Lance to provide details on our fourth quarter financial performance and 2026 guidance.
