Good morning and thank you for joining us for our first-quarter earnings call. 2022 has begun exactly as 2021 ended for both Axcelis and the industry, with significant demand for chips in the capital equipment required to produce them. Turning to Axcelis, specifically, the adoption of the full Purion product family has been strong and continues to gain momentum across the large and growing customer base. Customer satisfaction remains our top priority. Today, despite the challenging supply chain and logistics environment, solid execution by the full Axcelis team has allowed us to keep up with this high level of customer demand, need shipments, and maintain high levels of customer satisfaction. I would like to thank our dedicated employees once again for delivering these results under these challenging conditions. As a result of this demand and our strong execution, our first-quarter financial performance was well above our guidance. Revenue for the first quarter was $203.6 million with earnings per share of $1.22, gross margin of 44.1%, and the quarter-end cash balance of $297.9 million. Our aftermarket business or what we refer to as CS&I, continued to contribute significantly to our revenue and gross margin. CS&I revenue in Q1 was $51.8 million. The growing mature process technology market continues to be an area of strength for Axcelis with 81% of first quarter shipments going to mature foundry logic customers, and 19% to memory customers with NAND accounting for 9% and DRAM 10%. Our geographic mix was spread more evenly around the world due to significant global investment in the mature process technology market. The resulting mix of our system shipments in the first quarter was China 32%, Korea 18%, Europe 13%, Taiwan 11%, the U.S. 10%, Japan 6%, and the rest of the world, 10%. Visibility for 2022 continues to be good from a demand perspective, with significant orders for 2023 already booked. As a result, Axcelis now expects to achieve revenue of greater than $850 million in 2022. For the second quarter, we expect revenue of $205 million to $215 million, gross margin of approximately 41%, operating profit of approximately $41 million and earnings per share of approximately $1. Our guidance reflects increases in supply chain and logistic costs that are impacting our gross margin and operating expenses. In a few minutes, Kevin will provide more color on the actions we're taking to mitigate these challenges. The industry is in the strongest cycle ever seen and continues to be driven by the same factors we've discussed last quarter. In addition to a strong market, the implant TAM has increased significantly to approximately $2 billion and investment in the power market, both silicon and silicon carbide continues should grow rapidly. Power devices are more implant-intensive and require our more advanced Purion product extensions. We expect the power segment to account for between 30% and 40% of our system shipments in 2022. This growth is a long-term trend driven by the transition to electric vehicle and should benefit Axcelis for many years to come. Overall, we expect that the mature markets will account for approximately 80% of our total system shipments in 2022. We expect memory in 2022 will approach revenue levels seen at the last peak. In 2021, memory accounted for 17% of systems revenue. And we expect it to be approximately 20% in 2022. We maintain a strong and growing position in memory. In April, we shipped a Purion H high current evaluation to a new memory customer for a DRAM application. Also, in April, we shipped the Purion H evaluation system to a new fab at an existing mature process technology customer. These two Purion H evaluation shipments will position Axcelis for further growth in the high current market, the largest implant products segment. Now I'd like to turn it over to Kevin to discuss our financials and provide an operational update. Kevin?
