Thank you, Marcel, and good morning, everyone. I will start my comments as I always do, with a brief update on our safety performance, which is a core value at GrafTech. As I indicated on our year-end call, improvement in this area is a key point of emphasis with our team in 2023 as our prior year performance did not meet our high standards. I'm pleased that our recordable incident rate for the first quarter of 2023 is well below where we were throughout 2022 and places us among the top operators in the broader manufacturing industry. We will remain highly diligent in this area and seek to build on this momentum as we continue working toward our ultimate goal of zero injuries. Let me now turn to the next slide for an update on steel industry trends as additional context for our first quarter results and outlook commentary. During the first quarter, while we saw encouraging signs among key market indicators, the overall recovery of the steel industry remains somewhat constrained. Global steel production, excluding China, in the first quarter of 2023 was approximately 198 million tons. This represented a 2% sequential improvement from the fourth quarter but a 7% decline compared to the same period in the prior year. This same trend carries through to global capacity utilization rates, excluding China, which increased slightly on a sequential basis to 65% in the first quarter but remained down compared ameremain down by approximately 500 basis points year-over-year. Looking at some of the regions in which we participate. In Europe, we continue to see a stabilization of key trends, including steel production and pricing, although both remained significantly below year ago levels. In the U.S., utilization rates continue to tick up, averaging 74% for the first quarter with HRC prices rising significantly through the quarter. This sequential step-up in U.S.-based steel trends reflects improved auto production and construction spending, among other factors. While these trends are encouraging, we also recognize that a significant amount of economic uncertainty remains. This is reflected in the wide range of possibilities presented in the outlook of key market participants. Turning to GrafTech's first quarter performance. Our production volume was approximately 16,000 metric tons, representing a 66% year-over-year decline and resulting in a combined capacity utilization rate for our 3 primary electrode facilities of 31% for the quarter. As we have indicated, towards the end of the fourth quarter, we began to proactively reduce production at our European manufacturing facilities. Combined, our facilities in Calle and Pamplona operated at just below 1/4 of their capacity for the first 3 months of 2023. We expect to increase output in the second quarter and then increase further in the back half of the year based on steel market conditions. This is being done to align our production volume with our evolving outlook for graphite electrode demand as well as to manage high energy costs more efficiently. For our Monterrey facility, production output for the first quarter was in line with our expectations and reflected our focus on rebuilding our in-stock inventory levels. Turning to sales. Our first quarter sales volume of approximately 17,000 metric tons was in line with our expectations. The impact of Monterrey being suspended in late 2022 during a key commitment window for customer purchases covering the first half of 2023 was the primary driver of the 61% year-over-year decline in sales volume in the first quarter. Lower demand for electrodes also contributed to the decrease. Further, the terms for most of our LTAs ended in 2022, and our mix has shifted to more non-LTA business. First quarter shipments included 7,000 metric tons sold under our LTAs at a weighted average realized price of $9,000 per metric ton and nearly 10,000 metric tons of non-LTA sales at a weighted average realized price of $6,000 per metric ton. Both of these prices were consistent with our expectations. As a result of these combined factors, net sales in the first quarter of 2023 decreased 62% compared to the first quarter of 2022. As we proceed through the second quarter of 2023, while the residual impact of the Monterey suspension will continue to have a significant impact, we anticipate our sales volume will begin to recover and be in the range of 24,000 to 27,000 metric tons for the quarter. Non-LTA pricing is expected to decline slightly from first quarter levels, reflecting softness in the commercial environment. In the second half of the year, we anticipate our sales volume will further recover as we move past the Monterey suspension driven impact. However, as we've noted, given economic uncertainty and elevated graphite electrode inventory levels at our customers, we are now more cautious regarding our commercial outlook for the second half of 2023. Reflecting all of this, we currently estimate our full year sales volume will be in the range of 100,000 to 115,000 metric tons. Let me now turn it over to Tim to cover the rest of our financial results.
