Great and thank you, Ellen. Good morning, everyone and thank you for joining us today. At Talen, we remain focused on operating our assets in a safe and reliable manner, ensuring we deploy robust commercial hedging strategies and emphasizing disciplined cost management and returning capital to our shareholders. You can see these highlights on Slide 3 of our earnings presentation. Today, we are reporting solid operational and financial performance for the third quarter. During the quarter, our fleet generated $224 million of adjusted EBITDA and $146 million of adjusted free cash flow. The PJM plants ran well in a mild summer with strong cash flows supported by hedge gains. Our commercial hedging strategy provided the appropriate risk mitigation for a weak market and allowed Talen to lock in prices for our PJM fleet, which continues to support our cash flow generation for the year. In ERCOT, record temperatures and elevated spark spreads enabled our plants to generate significant physical energy margin, which we define as unhedged margin from generation and ancillary services. However, these results were negatively impacted by unplanned outages, including at our Nueces Bay plant, as well as abnormally high congestion costs in ERCOT at our plants. Terry will talk more about this in greater detail later and I'll try to unpack it as well. As a result of these outages and congestion costs, we are narrowing our 2023 guidance by reducing the upper end of our adjusted EBITDA range provided in August to $1.175 billion. This reflects the loss of upside opportunities from these events. The impact on 2023 adjusted cash flow is minimal, despite this loss and potential upside due to certain cash flow improvement activities that we have taken to offset the EBITDA. Turning to 2024, we are also establishing '24 adjusted EBITDA and adjusted free cash flow guidance ranges with midpoints higher than the January 27 disclosure forecast. These increases are driven by our new company-wide cost savings initiative, which is expected to result in $50 million of annual run rate cost reductions. Terry will provide more detail about these ranges and the cost initiatives in a bit, but this is allowing us to drive higher free cash flow per megawatt and increase our guidance. While we were unable to get into specifics, given this is an active ongoing process, we're making significant progress on the monetization of our data campus and remain excited about the ability to unlock significant value for Talen, through both an upfront return of capital and through future contracted nuclear cash flow growth from attractive long-term purchase power agreements or PPAs. A few weeks ago, we highlighted this value proposition at our site visit day, hosting over 70 investors and analysts for tours of Susquehanna and the Cumulus campus. Lastly, we continue to prioritize disciplined capital allocation and return of capital to shareholders. As announced last month, given our cash flow generation and modest leverage, our Board has authorized a $300 million share repurchase program through the end of 2025. Turning to some of our results on Slide 4 of the presentation, we performed reliably and safely, with an OSHA total recordable incident rate of 0.7 on a year-to-date basis and we continue to emphasize safety across our fleet. RTR IR is one of the best among peers. Our fleet ran well, generating 24 terawatt hours year-to-date with an equivalent forced outage factor of 3.5% so far this year. Approximately 53% or just over half of that generation was carbon-free from our Susquehanna nuclear facility. The solid operational foundation and strong commercial strategy we've built translated to $998 million of adjusted EBITDA year-to-date. And after funding interest, maintenance CapEx, pension payments and taxes, we generated $609 million of adjusted free cash flow for the same period. However, you'll note that our guidance for 2023 is $550 million to $585 million of adjusted free cash flow. This is because in the fourth quarter, certain cash payments will reduce our full year cash flow. For example, debt service payments that happen twice a year, pension payments and certain capital expenditures. I'd like to take this opportunity to recognize and thank our employees across the fleet who have worked safely to deliver impressive results. These team members are key to our overall financial performance as they operate, maintain and improve our generation assets even during times of unseasonable weather. Without their hard work and commitment to excellence, none of this could be possible. Turning to Slide 5 and taking a closer look at our key operational updates, we saw contrasting stories for physical margin versus hedge performance in PJM and ERCOT this quarter. Our PJM fossil and nuclear fleet performed reliably, with a forced outage factor of approximately 4% and 9 terawatt hours of generation in the third quarter. This fleet, the PJM fleet, faced mild summer temperatures that reduced power demand to one of the lowest levels seen in years. This, in combination with low natural gas prices, weakened power prices and led to lower physical energy margins. However, this was largely mitigated in our PJM cash flows by significant gains from our hedge program. One other PJM operational update is that as of last Friday, Susquehanna Unit 1 went into an unplanned outage which is not associated with the reactor. The unit was manually brought off-line and there are no safety or environmental issues. The team is currently working to bring the unit back to service and I am confident that Brad and his team will return Susquehanna to full operations safely. Turning to ERCOT. Strong performance from our fleet during the summer of record heat and spark spreads drove healthy physical energy margins. We collected additional revenues from taking advantage of ancillary services, especially at our Quick Start Laredo plant. However, this physical energy margin was largely offset by unplanned outages and elevated congestion costs across the ERCOT fleet. Nueces Bay experienced two outages during the quarter. One during tropical storm Harold in late August that was eventually resolved, and another that started in September due to a failure of the main power transformer. We're currently working to repair the transformer as quickly as possible, and the plan is estimated to return to service later this month. In addition to repairing the existing transformer, we also purchased a spare, which is expected to be on site later this year. And that spare has the advantage of providing backup for both Nueces Bay, as well as Barney Davis. The record demand levels this quarter, along with the transmission line constraints and derates materially worsened congestion in South Texas. Thus causing our generation assets to experience lower pricing at the node pricing point when compared to the south zone hub price. To give you a sense of these congestion costs, during the third quarter in '21 and '22, these costs average less than $5 a megawatt hour. But in 2023, they averaged over $25 a megawatt hour. These increased congestion costs, while somewhat mitigated, reduced our hedged EBITDA in ERCOT. Lastly, we recently decided to keep our Barney Davis Unit 1 running rather than suspending it in November and have notified ERCOT of our intent to operate the unit in 2024. We believe that the market dynamics in ERCOT provide opportunity to dispatch thermal generation during periods when renewable generation is not able to meet the incremental demand, such as during the peak demand hours of the summer as well as year-round during the hours when solar generation is ramping down at Sunset. Turning to Cumulus. We're making continued progress on monetizing the campus via a potential sale or JV. Both of these alternatives can unlock value, as I've said before, through a significant upfront, return of invested capital and through future Susquehanna cash flow growth through long-term purchase power agreements that would be at a premium to the nuclear PTC. To give you an example of the cash flow growth at Susquehanna through a PPA, assuming 240 megawatts, which is our campus infrastructure ready to support next year, an illustrative price of $70 per megawatt hour, which is $25 above PTC floor 45, would translate into over $50 million of incremental Susquehanna annual cash flows at the 240 megawatt level. And given recent nuclear transactions have created a cash flow yield of 10% or less, using this metric, it implies a significant value creation opportunity. And we think about scaling that to a full 950 megawatts, which would provide a clear line of sight to incremental compounded cash flow growth at Susquehanna over the next decade. That is why we think the combination of Susquehanna and the Cumulus data campus is so compelling. Given our progress on data, we have also started evaluating how we will recapitalize Cumulus and the strategic alternatives for our coin business. We are excited about the value creation opportunity across the Cumulus family of businesses and we are working hard to make it a reality. And with that, I'll turn it over to Terry.
