Thanks, Kristina. Good morning, everyone. Let me first share our view on the macro environment. In the first quarter, volatility in the global energy market remained high, driven by uncertainties around the potential for recession, the pace of China's economic recovery and the impact of sanctions on Russian products. At the same time, supply remains tight, supported by nearly 4 million barrels per day of global refining capacity that has come offline in the last couple of years. Global demand continues to grow as the need for affordable, reliable energy increases throughout the world. IEA is projecting 2 million barrels a day increase in 2023. Since last quarter, distillate cracks have come down, gasoline cracks have improved as expected given the onset of the summer driving season. So overall, we believe supply constraints and growing demand will support strong refining margins throughout 2023. Cracks have decreased from 2022 levels but still above historic mid-cycle levels. In alignment with what we said last quarter, we remain bullish into the driving season, and gasoline strength is expected to improve the diesel situation, while jet demand continues to improve. As we continue through the year, much will depend on the ongoing recovery in China and the extent, if any, of recessionary impacts. We continue building out our global presence, supported by our offices in Houston, London and Singapore as we invest in our global commercial strategy. And our cost advantaged refining system is well positioned to supply growing markets. This quarter, despite significant planned turnaround work at several key facilities, in particular, in our Gulf Coast region at Galveston Bay and Garyville, we delivered the strongest first quarter results in the company's history. Planned maintenance activities reduced refinery throughput by 11 million barrels compared with the fourth quarter. Our team's operational and commercial execution supported our ability to generate Refining & Marketing segment adjusted EBITDA of nearly $4 billion or $15.09 per barrel. MPLX remains a strategic part of MPC's portfolio as it continues to grow its cash flows and capital returns. Our Midstream segment delivers durable and growing earnings. This quarter, it generated adjusted EBITDA of $1.5 billion, which is up 9% year-over-year. MPLX distributions to MPC was roughly $500 million this quarter and an annualized rate of over $2 billion, which fully covers MPC's dividend as well as half of our planned 2023 capital program. During the first quarter, we advanced value-creating projects. At Galveston Bay, we completed the STAR project. Rather than expand the GBR cokers, we elected to upgrade the resid hydrocracker unit as it offers better conversion and increased liquid volume yield. Fractionation modifications offer increased diesel recovery and the refinery will be able to process significantly more discounted heavy crude. Overall, STAR is expected to add 40,000 barrels per day of incremental crude capacity and 17,000 barrels a day of resid processing capacity. Start-up activities are progressing and we expect STAR to ramp through the second quarter of 2023. The incremental profitability from this project will primarily be determined by the spread between heavy crude and untreated diesel over the incremental 40,000 barrels a day of crude capacity. At the Martinez renewable fuels facility, we reached full Phase I production capacity of 260 million gallons per year of renewable fuels, ramping to design rates and yields as planned. Phase II construction activities are on schedule. Pretreatment capabilities are expected to come online in the second half of 2023, which will enable the facility to ramp to its full expected capacity of 730 million gallons per year by the end of 2023. Martinez will be among the largest renewable diesel facilities in the world, underpinned by a competitive operating and capital cost profile, robust inbound and outbound logistics flexibility and advantaged feedstock slate and our strategic relationship with Neste. In the first quarter, we returned over $3.5 billion to MPC shareholders via dividends and share repurchases. And today, we announced an additional $5 billion share repurchase authorization reinforcing our commitment to strong capital returns. Let me share some of the progress on our low-carbon initiatives. The Martinez indicative facilities are competitively advantaged. They're supported by upstream value-creation integration with our Beatrice and Cincinnati pretreatment plants and downstream integration with our vast marketing footprint. The strategic partnerships we're cultivating with Neste, ADM and the Andersons creates platforms for additional collaboration within renewables. This quarter, we had an investment in an emerging producer of dairy farm-based renewable natural gas, providing the ability to participate in early-stage development at an attractive entry point. Our Virent subsidiary is progressing a commercially feasible assessment for converting bio-based feedstocks in the gasoline and sustainable aviation fuel. We believe for these projects and opportunities we are taking steps to advance our goal to lower the carbon intensity of our operations and the products we manufacture and supply to a growing market. At this point, I'd like to turn the call over to Maryann.
