Thank you, Eric, and good morning, everyone. I appreciate you joining us to review Vistra's third quarter 2025 results. This year continues to be a transformational one for our company, and the activity during the quarter was a key driver of our progress. We announced the landmark power purchase agreement at Comanche Peak, announced our plan to develop 2 gas-fired units in West Texas and successfully closed the acquisition of approximately 2.6 gigawatts of natural gas-fired assets from Lotus Infrastructure Partners. Importantly, while we are successfully advancing our growth efforts, we continue to be steadfastly focused on execution in our core business. As we will discuss, our core business continues to point to additional value creation in the years ahead. I'm proud of what our team has accomplished this year as we continue building the foundation for sustainable growth and value creation well into the future. Continuing on the topic of sustainable growth on Slide 5, you can see the positive impact of steps we've taken over the past several years. Combined with a more favorable demand backdrop, those actions are now translating into sustainably higher levels of profitability for our company. At the core of this success are the approximately 7,000 team members across the organization. Their dedication and hard work allowed us to deliver another solid quarter of financial performance. Combined with our results year-to-date, we are narrowing our guidance range for 2025 adjusted EBITDA to $5.7 billion to $5.9 billion, and our 2025 adjusted free cash flow before growth to $3.3 billion to $3.5 billion. Moving to our near-term outlook. We are introducing guidance ranges for 2026 adjusted EBITDA of $6.8 billion to $7.6 billion and adjusted free cash flow before growth of $3.925 billion to $4.725 billion, including the expected contribution from the assets acquired from Lotus Infrastructure Partners. It's worth noting that excluding the benefits from the Lotus assets, the midpoint of our 2026 adjusted EBITDA guidance range is above our previously communicated 2026 adjusted EBITDA midpoint opportunity of $6.8 billion plus, another clear sign of sustainable momentum across our business. We are confident in our forecast as we expect consistent earnings from our retail business paired with strong performance from a reliable, flexible and highly hedged generation fleet. Finally, for 2027, we are introducing an adjusted EBITDA midpoint opportunity range of $7.4 billion to $7.8 billion. While multiple drivers of gross margin variability remain, including the 2027, 2028 PJM capacity auction, our hedge percentage, which currently sits at approximately 70% of expected generation, provides line of sight to our adjusted EBITDA midpoint opportunity. Finally, the recently announced power purchase agreement at Comanche Peak marks a major milestone for our company, for our site and for Texas. We believe this 20-year agreement, which enables our customer to energize up to 1,200 megawatts of new load ensures the Comanche Peak nuclear plant will continue to deliver power to Texans at least through the middle of this century. As you may recall, we recently relicensed Comanche Peak out to the 2050s, and this agreement provides the financial backing to maintain operations through that date and potentially beyond. Further, the customer's commitment to bring significant backup generation to the site will also enhance resource adequacy while meeting their own reliability needs. I want to commend our team for their hard work and constant dedication in getting this agreement over the finish line, working, of course, very closely with our customer. We believe this is yet another example of why Vistra is a reliable and trusted partner for these types of long-term agreements needed to meet the ever-increasing power demand across the U.S. We continue to see multiple pathways for long-term agreements at other sites as we believe our fleet and development capabilities are well positioned to provide a variety of power solutions to meet the needs of these large load customers. Turning to Slide 6. Our 4 strategic priorities remain integral to our success. We believe our integrated business model and comprehensive hedging program provide our stakeholders greater visibility into our future financial performance. Our diverse fleet of generation assets, combined with our trusted retail brands and strong commercial acumen form an integrated platform that consistently delivers attractive earnings and downside protection. Our generation team achieved another solid quarter of commercial availability of approximately 93% for our coal and gas fleet. This included exceptional performance during the late July nationwide heat wave and the impacts of the extended outage at one of our 3 Martin Lake units. Nuclear also had a solid quarter of performance, achieving a capacity factor of approximately 95%. Complementing our generation portfolio, our commercial team continues to deliver strong results through disciplined execution over a comprehensive hedging strategy. We've established a highly hedged position for '26 as we enter the year, providing enhanced earnings visibility and stability. Over the next 12 months, the team will continue to prudently manage our open length for '27 to further strengthen that position. As I'll discuss later, we are also making solid progress in advancing additional capacity contracts with large load customers, which will further enhance the long-term value of our company. On the Retail side, we continue to see strong customer count growth driven by our portfolio of brands in the Texas market. We believe the team's continuous innovation combined with strong customer service drives the consistent earnings level of the business while outperforming on customer complaint, performance versus our key competitors and maintaining our 5-star ranking. Switching to capital allocation, we remain disciplined in our approach by targeting a significant return of capital, executing on our attractive growth project pipeline and maintaining a strong balance sheet. Since implementing the capital return plan put in place during the fourth quarter of 2021, we have returned over $6.7 billion to our shareholders through share repurchases and common stock dividends. Kris will cover capital allocation in more detail later in the presentation, but you will see that we expect to return at least an additional approximately $2.9 billion through share repurchases and common dividends, including the additional $1 billion authorized this quarter by the Board for share repurchases through 2027. Turning to growth. With the increasing power needs in West Texas, including from the state's expanding oil and natural gas industries, combined with expected demand growth from data center additions, we have made the decision to move forward with developing 2 natural gas units totaling 860 megawatts. We view these projects as attractive for our owners with projected returns in excess of our mid-teens levered return thresholds. Both units remain part of the Texas Energy Fund due diligence process, and we plan to make a final decision on financing in the coming months. Equipment and EPC procurement is progressing well, and we remain on track to deliver this West Texas capacity in early to mid-2028. Lastly, we successfully closed on our acquisition of 7 natural gas plants from Lotus Infrastructure Partners, totaling approximately 2,600 megawatts of capacity. This acquisition, which includes assets across PJM, New England, New York and California reflects our disciplined and opportunistic approach to M&A. It will enhance our already wide geographic footprint and strengthen our ability to meet the diverse needs of our customers. We look forward to integrating these assets into the Vistra portfolio and driving operational efficiencies by running them in line with the high standards of our current large combined cycle and peaking gas fleet. We continue to target approximately $270 million of adjusted EBITDA from these assets in 2026, with potential upside in the out years driven by synergies and higher capacity revenue. Moving to the balance sheet. We continue to prioritize liquidity and low leverage to manage the business prudently. While we currently have a strong balance sheet with leverage of approximately 2.6x, we expect additional deleveraging through the end of 2027 through higher earnings and continued prudent management of our debt levels. As we stated on our last call, we believe the lower leverage levels, combined with a reduction in business risk as a result of more contracted revenue sources, puts us on the path for an upgrade to investment-grade credit ratings. On our strategic energy transition, we continue to execute on our strategy of utilizing existing land and interconnects to develop solar and energy storage projects. Our Oak Hill solar project in ERCOT reached commercial operations last month, bringing 200 megawatts of clean energy to the ERCOT grid. Our Pulaski and Newton sites remain on schedule for commercial operations by year-end 2026. We continue to evaluate the remainder of our development portfolio for additional opportunities as long-term power agreements materialize. Finally, we believe nuclear, with its carbon-free profile and 24/7 availability, is a vital component in meeting the country's electricity needs for decades to come. Large load customers clearly have a preference for this type of generation. To meet these needs, we continue to evaluate upgrade opportunities at our nuclear plants with studies planned to be completed by the end of this year. Initial assessments are promising, indicating the potential to increase capacity at nuclear plants by approximately 10%, with the additional capacity starting to come online in the early 2030s. Turning to Slide 7. We continue to see a structurally improved demand environment, which carries significant positive implications for our business. As we've discussed over the past several quarters, electricity consumption across the country is undergoing a fundamental shift. Load growth in our largest markets remains well ahead of national averages. With weather-normalized load in PJM rising approximately 2% to 3% and the ERCOT market growing around 6% year-over-year. Importantly, customer investment continues to send stronger, more sustained market signals. Data center development remains robust with a number of planned facilities across the U.S. more than doubling from 12 months ago. Our largest markets, PJM and ERCOT, continue to be targeted for a larger share of these developments. As an example, ERCOT's market share of these announcements is over double the region's market share of currently installed data centers. While it's unlikely that every announced project ultimately reaches completion, even factoring in a haircut, we believe this data indicates the load growth levels we covered at the top of the slide will materialize. In fact, we continue to see the potential for even greater acceleration. This is especially evident in recent results calls from the hyperscalers where they've emphasized expanded investments in AI and data infrastructure, signaling that development activity is expected to remain strong, if not increase further, in the year ahead. This load growth is already leading to higher utilization rates for our combined cycle gas assets where capacity factors have increased from the low 50% range to the high 50s over the last several years. Growing consumption should efficiently drive existing assets to higher utilization levels over time, potentially reaching rates in the mid-80% range for combined cycle gas plants. This is evidence that there is capacity currently on the grid capable of meeting the load growth anticipated over the next 3 to 5 years. In addition to supply-side solutions, there is also increasing interest in demand-side solutions. The infrequent super peak hours can also be met through practical solutions like on-site backup generation and demand response, approaches that large load customers are continuing to develop and implement. This framework supports accelerating demand growth from emerging sectors such as data centers, crypto operations and other industrial load, allowing them to integrate into our markets by leveraging existing grid investments, while improving system utilization and lowering unit costs for end customers. Turning to Slide 8. Vistra is in the middle of a multiyear plan to drive significantly higher profitability levels against the backdrop of accelerating electricity demand growth just outlined. The team has already delivered on several initiatives that have led to our increased outlook through 2027. Our retail business consistently achieved strong margin performance and high levels of free cash flow conversion. Our commercial team through our comprehensive hedging program, lock in benefits from stronger power markets, while our generation team looks for attractive and cost-effective ways to organically add capacity, such as our natural gas upgrades in Texas. Inorganic expansion has also been a big value driver through both the acquisitions of Energy Harbor and the natural gas plants from Lotus. However, we see an extensive list of near-term and long-term opportunities that are not included in our outlook that will enable us to grow our business through the end of the decade and beyond. Some of these initiatives are already underway, such as the 1,200-megawatt power purchase agreement at Comanche Peak, or the Coleto Creek coal-to-gas conversion, and these are expected to begin contributing to profitability in the next few years. Projects like the new Permian gas units and the Miami Fort coal-to-gas conversion are in the early stages of project execution. Others such as the nuclear uprates, while still early in the process, could provide significant additional optionality around our assets. Long-term power purchase agreements will also be a key driver of increasing our earnings visibility, and we see multiple pathways to agreements across our large diversified fleet of more than 40,000 megawatts of nuclear, gas, coal and renewable generation. We also see numerous opportunities for contracting new build capacity across our geographies and our experienced development team is actively progressing these options. We continue to see an acceleration in strong customer interest we outlined last quarter, and we believe the momentum we have today should enable us to realize multiple contracting opportunities. In fact, we set aside roughly $50 million per year over the next several years, including 2026, and increased expenses for investments in people and development activities to capture these opportunities and handle the level of customer interest. Importantly, all the potential future drivers I've outlined remain incremental to the core objective of delivering for our customers for running an efficient and reliable fleet that benefits from improving power market fundamentals. We believe there is significant optionality embedded in our large generation fleet, particularly our combined cycle and peaking gas fleet given that strong market fundamentals can drive higher volumes and higher revenue without significant incremental investment. Now I'll turn it over to Kris to provide more details on our third quarter results, outlook and capital allocation. Kris?
