Thanks, Leah, again who started this morning. And thank you Emily for that. Good morning everyone and thank you for joining our first quarter earnings call. I'm going to start on slide 5 of the deck. Once again, we're off to a strong year operationally and financially, thanks to the focus and dedication of the women and men that do their best every day to produce and deliver clean reliable and affordable electricity to our customers. For the first quarter, we earned $658 million in adjusted EBITDA. But the top line story here is that based upon our performance to date, we can project that we will end the year comfortably in the top half of our guidance range. And if we continue to execute, we expect to be at/or near the top of that range. In addition, 2024 looks better to us than when we reported in February. Our commercial team had a tremendous quarter, not only generating better than planned earnings in the quarter, but they were able to lock in value for the remainder of this year and for next. On the back of their strong execution, our gross margin is up $50 million in 2023 and $100 million in 2024. As Dan will cover, all-in 2023 is up $100 million from where we were in February. For 2024, we expect to come in notably above current consensus, which you could see using our disclosures on page 25 of the presentation. And in our gross margin update, you'll also see how the PTC interacts with our portfolio to add value in the face of lower commodity prices. We think that the message here is pretty simple, our company had a strong first year and is on track to have great years two and three. Our business is unique and we still have many opportunities in front of us to create value for our owners. We are the best operator of nuclear plants and the largest producer of carbon-free clean energy in the United States. We produced approximately 11% of our nation's clean energy last year. Our commercial business serves 25% of the entire competitive C&I market in the United States, 75% of the Fortune 100. Our businesses are essential to addressing climate change and will be needed for decades to come to provide clean and reliable energy as America simultaneously reduces its reliance on fossil fuels, and the transportation industrial agriculture and residential sectors, all increasingly turn to electrification to reduce harmful pollution. The Inflation Reduction Act, the IRA provides unique opportunities for Constellation and its owners. Through the Nuclear Production Tax Credit, the US government has made a long-term commitment to our nation's nuclear assets recognizing that without them we simply cannot meet the climate goals. The PTC provides downside commodity risk protection as you could see in our disclosures today, while ensuring that our plants remain economic and reliable. The PTC protection level rises with inflation, providing us structural inflation risk protection. Other provisions of the IRA create unique growth opportunities like increasing the output from our nuclear plants through uprates and hydrogen. And finally it gives us the opportunity to extend the time horizon of our fleet to 80 years. And we've made this point I'll make it again, no other clean energy asset except hydro can run for this long without being replaced. We have many ways to grow and bring more value to our shareholders. Against the baseline earnings level, support provided by the PTC over the life of the PTC, we will benefit from forward price inflation that grows with overall inflation in the country. And as you can see on slide 18 depending on your assumptions about inflation there are some meaningful top-line growth opportunity ahead for us in the PTC. We generate strong free cash flow that can be used to fund robust organic growth at double-digit unlevered returns, disciplined M&A and fund a growing dividend and the buyback of our stock. Each of these will create additional value for our shareholders. And we're already doing this. We have announced $1.5 billion of growth in uprates, hydrogen and wind repowering double the per share dividend. And in March alone we bought back approximately $250 million of our own stock as part of our authorized $1 billion buyback which we will execute. And there's more we can do. We have $2 billion of unallocated capital in 2023 and 2024 that can be used to further enhance our earnings growth. At our current stock price, I'd be happy to use this capital to continue buying back our stock all day long. We will continue to look for investment opportunities consistent with or adjacent to our core businesses, and we are committed to the energy transition. However in the absence of any near-term M&A opportunities or a ramp-up in growth CapEx, we will in the short-term use the majority of the $2 billion to repurchase our own shares. Constellation cannot be matched anywhere in this marketplace. Our clean carbon-free nuclear fleet paired with our customer-facing business provides us with opportunities to grow and create value for you. It is a unicorn. I'll turn next to our quarterly operational updates beginning on slide 6. Nuclear performance was strong and slightly ahead of plan. We produced more than 40 terawatt hours of reliable affordable and carbon-free generation from our nuclear plants with an on-plan capacity factor of 92.8%. As some of you may be aware during routine inspections during our Nine Mile Point 1's refueling outage, we identified an issue with non-safety-related well. It's not uncommon in the industry, but it did extend Nine Mile's outage to 39 days. The cost of the repair is absorbed within our existing budget. But the point I want to make here is that even with the extended outage at Nine Mile, we returned to service roughly in line with the industry average for a standard refueling outage of approximately 39 days. And the point here is that at Constellation a long outage is just average for everyone else. And while Nine Mile lagged our ability to lead the nation in returning units from outages was demonstrated at both Byron and Calvert Cliffs, which completed their refueling outages ahead of plan and at an average duration of 21 days in total. Our renewables and natural gas fleet also performed well with 96.6% renewable energy capture and 98.4% power dispatch match. The team is presently completing our summer readiness work to make sure that it's ready for the hot summer months to come. Turning to slide 7. I'll talk a little bit about the Commercial business, but I already mentioned before they've had an incredible start to the business. It's a business that benefits from the opportunities that volatility in the commodity markets creates. We're able to leverage our expertise to give our customers certainty of their energy costs in this volatile market environment, while realizing higher unit margins across both wholesale and retail as risk is more appropriately reflected in pricing. Our balance sheet strength is a key advantage to supporting our customers and being able to capture these healthy margins. Providers with more constrained balance sheets and less experience with volatile markets are not able to provide customers the certainty and the visibility that our customers desperately want and need. Our balance sheet strength allows us to provide this needed certainty to our customers. We operate our generation and customer businesses symbiotically with each other supporting and making the whole stronger. As such, we can optimize our positions across the combined generation and workload portfolios to create additional gross margin, particularly, in times of volatility. And again, I'll just hit this I think the results this quarter and what we've predicted for the remainder of the year and next demonstrate all of this. And we have continued success developing and providing sustainability products like core to our customers. As I mentioned earlier, this strong performance creates additional value for you both in 2023 and 2024. And before I turn it over to Dan for a full update on the financial outlook I want to address our O&M disclosures from the last call. We're confident in the firmness of our forecast and the entire management team is coming committed to ensuring that this forecast is met and it will be met. We will always look for additional opportunities to run our business as efficiently as possible. Dan?
