Thank you, Eric, and good morning, everyone. Thank you for joining us to discuss Vistra's fourth quarter and full year 2025 results. 2025 was a transformational year for Vistra. We made a number of moves that I believe underscore the value of our integrated model. We executed strategic asset acquisitions and entered into long-term power purchase agreements, accomplishments that were made possible by close collaboration across the company, including development, operations and commercial as well as our retail and functional teams. This tightly coordinated execution is a direct result of the focus and discipline of our people and reflects the One Team culture that drives our strong performance at Vistra. These accomplishments demonstrate our ability to deliver industry-leading power solutions to our customers, execute complex transactions and deliver day-to-day operational excellence, all while driving significant value for our shareholders. We remain confident in the ever-increasing customer demand for power, enthusiastic about the growth opportunities that load growth presents for Vistra and eager to continue to partner with our customers to realize those opportunities and serve their needs. We look forward to building on this momentum as we move through 2026 and beyond. Turning to Slide 5. Our integrated business model once again demonstrated its value and effectiveness as we delivered another year of record financial performance. For the full year, we achieved approximately $5.9 billion of adjusted EBITDA and approximately $3.6 billion of adjusted free cash flow before growth, both meaningfully above the midpoint of our original guidance ranges. These results reflect consistent operational performance from our generation, commercial and retail teams. The importance of operating assets safely and reliably was underscored during Winter Storm Fern at the end of January. During the 9-day event, where we saw significant cold front impact most of the U.S., including temperatures below 0 in West Texas and the Northeast, the team and the generation fleet delivered very strong performance. Our team not only operated safely during difficult weather conditions, but also ran our assets extremely well during the event. This, coupled with our commercial risk management approach, enabled us to serve our millions of retail customers and deliver a positive financial outcome, despite the high volatility of both gas and power prices. Moving to growth. We took meaningful steps during the year to expand and strengthen our generation portfolio. In October, we closed the acquisition of 7 modern natural gas generation facilities totaling approximately 2,600 megawatts from Lotus Infrastructure Partners. This transaction added highly efficient dispatchable assets across key competitive regions, including PJM, New England, New York and California. Winter Storm Fern was our first weather experience with these new assets, and we were pleased with their performance and with the value they added to our overall fleet. Building on the Lotus transaction, we recently announced our agreement to acquire Cogentrix Energy, which includes 10 modern natural gas generation facilities totaling approximately 5,500 megawatts of capacity, including 2 plants, Patriot and Hamilton-Liberty that were completed in 2016 with heat rates well below 7,000. Together with the Lotus acquisition, these assets will further diversify our fleet, improve our geographic balance and significantly strengthen our ability to meet the growing demand for dispatchable generation across the country. Owning and operating high-quality dispatchable generation in competitive markets is core to our strategy. We believe strategic acquisitions and asset integrations are one of our core capabilities that continue to deliver value to our shareholders. We also made significant progress contracting long-term nuclear capacity, enhancing the amount and durability of our cash flows. We have now contracted approximately 3.8 gigawatts of nuclear capacity through multiple power purchase agreements, including a 20-year agreement with Amazon Web Services for 1,200 megawatts at our Comanche Peak nuclear power plant in Texas and 20-year agreements with Meta covering 2,176 megawatts of operating capacity and an additional 433 megawatts of upgrades at our PJM nuclear plants, the largest nuclear operate supported by a corporate customer in the United States. We are excited to partner with these world-class companies to be able to continue to provide reliable 0 carbon electricity decades into the future. Overall, these and other actions taken in 2025 continue to strengthen Vistra's ability to reliably and affordably support the nation's growing power needs. Turning to Slide 6. For the eighth consecutive quarter, we continue to see a structurally improved demand environment that supports our long-term outlook. U.S. electricity consumption reached an all-time peak of approximately 4,200 terawatt hours during 2025, up about 2.5% versus 2024. We expect calendar years 2026 and 2027 to continue to show growth, which would mark the first 4-year period of sustained growth since the 4-year period ending 2007. Demand growth no longer appears to be episodic, but increasingly durable, a dynamic with important implications for the power sector. While the near-term outlook remains strong, we continue to believe the impact of data centers on tightening supply-demand dynamics will not meaningfully begin until late 2027 or early 2028, given most build schedules and interconnect timing. This is something we've been consistently messaging for some time. Load growth is real and significant, but it is likely not at the extremely elevated levels in the rapid time frame that has been forecasted by many third parties. The fact that we see the load growth coming more slowly than some forecast does not dampen our enthusiasm for the tremendous opportunities in front of us. In fact, we view a measured pace of growth as a positive. It naturally takes some time for supply and demand to go from concept to reality. We believe our company and the markets in which we operate can meet the moment. Our primary regions continue to outperform. We maintain our view that annual peak load growth of at least 3% to 5% in ERCOT and low single-digit growth in PJM is achievable through 2030. Importantly, we expect overall load growth to outpace peak demand, resulting in higher expected utilization across the system rather than short duration peaks alone, implying the economics of existing generation assets will improve on a sustained basis. Data center development remains robust, and we believe key markets such as PJM and ERCOT will continue to attract a disproportionate share of new load growth. While not every announced project will ultimately be built, even applying conservative assumptions, the level of activity supports the load growth outlook that we've discussed. Recent commentary from hyperscale customers reinforces this view as they continue to emphasize expanding investment in AI and digital infrastructure. Capital spending by the hyperscalers continues to rise to record levels and is expected to eclipse $700 billion in 2026, equivalent to roughly 50% year-over-year growth. This level of investment is notable and provides further support for sustained load growth. Demand growth creates meaningful opportunity for Vistra. Following the closing of Cogentrix, our large modern fleet of combined cycle gas generation assets will total approximately 26 gigawatts of capacity. Importantly, our fleet currently operates at a utilization rate of approximately 60%, and we continue to believe higher energy demand should drive materially higher utilization of existing assets over time, providing a practical and cost-effective way to meet load growth. Taken together, these trends underscore a demand environment that is structurally stronger than prior cycles, and Vistra is well positioned to meet growing electricity needs in our core markets. Moving to Slide 7. The Cogentrix acquisition represents the second opportunistic expansion of our generation footprint over the last 12 months. Similar to Lotus transaction, it is an acquisition of high-quality dispatchable assets in competitive markets at an attractive price that we believe will drive meaningful per share accretion. As I mentioned earlier, we believe successfully integrating and operating generation assets at scale is a core competency of the company as we've demonstrated time and again, starting with the Dynegy transaction and continuing with our Energy Harbor and Lotus acquisitions. For Cogentrix, we see similar opportunities to boost the portfolio's earnings profile over time as we get into our normal integration activities. From a financial perspective, we view the purchase price as attractive at approximately $730 per kilowatt of capacity, net of expected tax benefits, and we expect the transaction to deliver mid-single-digit adjusted free cash flow before growth per share accretion in 2027, with a high single-digit accretion on average over the '27 to '29 period. We look forward to closing the transaction in 2026 and welcoming our new team members to the Vistra family. More broadly, we continue to believe that natural gas generation will play a critical role in delivering reliable, affordable and flexible power to U.S. electricity markets. Winter Storm Fern reinforced this view. During the tightest hours, thermal generation accounted for approximately 93% of all power delivered to the ERCOT grid. Once again, demonstrating that when conditions are the most demanding, firm dispatchable resources are relied upon much more than on a typical day. We've seen this story repeat itself time and again during Elliott, Mara, Heather and now Fern. Given this backdrop, we will continue to evaluate future inorganic opportunities that create value within our integrated model. Moving to Slide 8. Our nuclear power purchase agreements represent a significant milestone, not just for Vistra, but for the industry. We have now signed approximately 3.8 gigawatts of nuclear capacity, including up rates under long-term contracts, more than any other power company in the country. These agreements executed with 2 of the world's leading technology companies represent meaningful long-term commitments to the safe and reliable operation of nuclear power generation in the United States. The first agreement, which we announced in September last year, is a 20-year contract with Amazon at our Comanche Peak nuclear plant in Texas. Under this agreement, Amazon will cite a facility on our property to utilize the 1,200 megawatts of capacity. Importantly, Amazon also plans to bring one-for-one backup generation, a structure we believe supports future expansion at the site, while maintaining reliability across the system. Progress on the site continues to be made with initial energization still expected in the fourth quarter of 2027 and full ramp expected by the fourth quarter of 2032. The agreement also includes options to explore new nuclear development with a specific focus on possible uprates and small modular reactors. We are excited about this partnership and the long-term potential at the Comanche Peak site. Building on that momentum, in January of this year, we announced long-term power purchase agreements with Meta. The agreements, which are also for 20 years, cover 2,176 megawatts of operating capacity from our Perry and Davis-Besse nuclear power plants and an additional 433 megawatts of upgrade capacity from our Perry, Davis-Besse and Beaver Valley power plants. We expect delivery of the operating capacity at Perry to commence in December of 2026 and Davis-Besse in December 2027. Uprate capacity remains longer dated with Perry upgrades expected to be online in the fourth quarter of 2031, with each subsequent year seeing an additional upgrade online until all 4 upgrades are completed by the fourth quarter of 2034. From an operating perspective, the plants will continue to operate as they do today with power flowing to the grid for the benefit of all customers. The financial impact from all of our nuclear PPAs is significant, providing the financial backing to operate these facilities for decades to come and in the case of the PJM nuclear sites to apply for additional license renewals and extend site operations into the 2050s and 2060s. Upon achieving full ramp of all the nuclear agreements, we see a pathway to nearly 25% adjusted free cash flow before growth accretion on an annual basis. From a capital perspective, the Comanche Peak agreement will not require significant incremental spend from Vistra and the PJM agreements for operating capacity won't require any additional spend. The PJM nuclear uprates will require growth capital over an 8-year period with the majority of the spend occurring after 2028. We believe these investments represent attractive growth opportunities given the higher capacity, expected improvement in reliability and the enhancements that will allow for an additional operational license extension, all while exceeding our mid-teens levered return requirements. Taken together, these nuclear PPAs position Vistra to support reliable carbon-free power as demand continues to grow, while also increasing and extending the earnings profile of our company for the longer term. While these agreements are important for our company, we have more we can do. We still see an opportunity to contract up to an additional 3.2 gigawatts of nuclear capacity across our Beaver Valley and Comanche Peak sites, including potential upgrades of approximately 200 megawatts at Comanche Peak. Continuing with the theme of an enhanced and more predictable earnings profile, let's move to Slide 9. We continue to make meaningful progress in derisking our business, locking in higher levels of contracted revenue while at the same time growing our total earnings. It's important to emphasize this point. We are not trading growth for stability. We are achieving both. Our percentage of contracted wholesale will increase substantially and shift the earnings certainty longer term and more insulated from changes with tax policy. This is particularly noteworthy as the earnings profile of the business continues to grow significantly on an absolute basis as well. On a consolidated basis, based on the contracts signed to date, when combined with the reliable contribution from our retail business, we expect nearly half of our total adjusted EBITDA to be generated from highly stable earnings sources, with the potential to increase this percentage as we execute on additional opportunities. This will be a meaningful shift in the composition of our earnings, reducing volatility, enhancing visibility and improving our credit profile. We continue to pursue attractive arrangements to serve our customers given the accretion to our business on many levels. Finally, turning to Slide 10. Our 4 strategic priorities remain core to delivering long-term value. With our One Team approach, we've demonstrated superior execution on these priorities. The acquisitions of Energy Harbor, Lotus and soon Cogentrix have proven to be valuable through adherence to price discipline, best-in-class integration and enhancements of scale. Our measured approach to development has enabled us to generate attractive returns, whether through contracted renewables such as Oak Hill and Pulaski or high-return thermal additions like our coal conversions, gas plant augmentations or Permian new build gas units. Turning to the balance sheet. Our prioritization of liquidity and low leverage has placed us in a strong financial position. Combined with the improved earnings profile of the company, we continue to expect leverage to decline and have been pleased to see multiple rating agencies recognize our improved credit profile. While this chart highlights the last few years, I would like to spend a minute on the future and how the continued execution of our 4 key strategic priorities will unlock multiple growth opportunities in the years ahead. Our generation development teams will continue to pursue highly accretive capacity additions. We continue to advance our plans to convert our Miami Fort facility in Ohio from coal to gas. While our targeted 500 megawatts of augmentations at our Texas gas fleet are largely complete, the team continues to study options at our current PJM fleet, which could total approximately 300 megawatts. Further, the team remains hard at work reviewing new PJM plant additions, which would likely involve expanding existing sites. Contracting work also continues. As I already mentioned, we still see an approximately 3.2 gigawatts of opportunities at Beaver Valley and Comanche Peak that can be contracted on a long-term basis. On the thermal side, we continue to make progress in our discussions with customers on new and existing gas solutions. We will continue to provide updates as those opportunities materialize. Finally, our retail team continues to deliver novel products to customers to help them better manage their budget, while meeting their power needs. The ability for customers to choose their provider, their electric plan and ultimately have some control over their energy needs is a proven way to address the concerns related to affordability. No matter the product category, customers prefer having a choice, and our team is working hard to make sure that we are the preferred choice of customers from residential to industrial, including the hyperscalers. Ultimately, we believe the combination of these capabilities position Vistra to be the energy solutions provider to our customers by developing and delivering innovative strategies to meet our customers' needs in this growing demand environment. I'm excited about what our team has accomplished and what we can deliver in the years to come. Now I'll turn it over to Kris to provide more details on the fourth quarter and full year results, outlook and capital allocation. Kris?
