As noted in our press release, dated April 6, 2021, we announced the appointment of Jim Schmidt as Chief Financial Officer effective June 1, 2021, succeeding Jamie Simms. Jim will also join the Vicor Board of Directors and serve as the Company’s Treasurer and Secretary. We are looking forward to having Jim join the company. I'll now turn to a review of our Q1 financial performance, after which Phil will review recent market developments, and Patrizio and Phil will take your questions. In my remarks, I will focus mostly on the sequential quarterly change for P&L and balance sheet items and refer you to our press release or our upcoming Form 10-Q for year-over-year comparisons. As stated in today's press release, Vicor recorded total revenue for the first quarter of $88.8 million, up 5.3% from the fourth quarter total of $84.3 million. Quarterly Advanced Products revenue rose 2.2% sequentially. This growth was constrained by limited component availability due to global semiconductor supply allocation issues experienced during the quarter. Brick Products revenue rose 7.6% sequentially, reflecting a resumption of shipments to our European customers after the pandemic-related trough of 2020, while Asian customers grew 18% from Q4 2020. These increases offset a modest sequential decline in shipments to North America. Shipments to stocking distributors rose 79% sequentially, primarily due to an increase in Brick Products shipments. Turns volume also increased sequentially. Exports for the first quarter increased sequentially as a percentage of total revenue, approximately 69% of consolidated revenue from the prior quarter 64%, reflecting the factors just mentioned regarding Europe and Asian shipments. For Q1, Advanced Products share of total revenue declined slightly to 39% compared to 40% for the fourth quarter, with Brick Products share correspondingly increasing to 61% of total revenue. We believe Advanced Products sales growth will expand significantly as a percentage of total revenues, especially once new manufacturing capacity comes online, given the high-growth segments we have penetrated with our 48-volt technology, including AI, data center and automotive, in contrast to the maturity of the segments we serve with Brick Products. Turning to Q1 gross margin. We recorded a consolidated gross profit margin of 50.3%. Higher volumes and improved mix contributed to higher profitability as did a reduction in cost variances and tariff charges. Gross margin dollars rose 11% sequentially. While margins remain under the pressure of high tariff charges, Q1 charge declined approximately 33% from Q4’s charge of approximately $1.5 million. We expect to see further improvement through 2021 in part reflecting our ongoing efforts to reduce component imports from China. I'll now turn to Q1 operating expenses. Total OpEx rose just under 4% sequentially, but consistent with longer-term trend, reflecting periodic swings in discretionary spending. The amounts of total equity-based compensation expense for Q1, included in costs of goods, SG&A and R&D were approximately $228,000, $853,000 and $490,000, respectively, totaling $1.6 million. For Q1, we reported operating income of $14.7 million, representing an operating margin of 16.6%. The sequential 27% increase in operating income reflects the operational leverage in our model. Turning to taxes, we recorded a net benefit for Q1 of $143,000, representing an effective tax rate for the quarter of minus 1%. Net income attributable to Vicor for Q1 totaled $15.1 million. GAAP diluted earnings per share was $0.34 based on a fully diluted share count of 44,841,000. Before I turn to our financial position, just a brief update about COVID-19 and our workforce. As previously discussed, the designated essential manufacturer using masks and practicing social distancing from the onset of the pandemic, we have continuously operated three shifts at our Andover manufacturing facility. While we have seen a small increase in cases, again, recently, cases are below the levels experienced in the December through January timeframe and absenteeism has declined. Nevertheless, because much of the potential influence of the COVID-19 pandemic is associated with risks outside of our control, we cannot estimate the extent of such influence on our financial or operational performance or when such influence might occur. Turning to our cash flow and balance sheet. Cash, cash equivalents and short-term investments totaled $223 million at Q1, a sequential increase of 5%. Accounts receivable net of reserves totaled $47.7 million at quarter-end, an increase of 16.3% over Q4 with DSOs for trade receivables steady at 38 days. All balances are current. Inventories net of reserves declined 5.3% sequentially to $54.3 million. Annualized turns improved to 3.11. Reflecting the positive operating results, operating cash flow totaled $17.6 million for the quarter. Capital expenditures for Q1 totaled $9.3 million. We ended the quarter with a construction in progress balance of $19 million, leaving approximately $38 million of our capital budget scheduled to be spent through the year. Our factory expansion project is proceeding on schedule and on budget. I’ll now address bookings and backlog. Q1 bookings totaled $99 million, 8.1% sequential increase. The overall book-to-bill was approximately 1.1 with Advanced Products at 1.4 and Brick Products at 1.0. Q1 bookings largely reflected the same circumstances we saw with shipments, growth in Europe and Asia with a modest decline in North America. At year-end, one-year backlog totaled $157.1 million, an increase of 6.5% sequentially. Turning to our outlook for the second quarter of 2021. We expect revenue growth. We continue to address the sources of gross margin pressure and our forecasting improvement and product level profitability. Further, we do not anticipate any meaningful increase in operating expenses. While substantial further improvements in gross margins will have to await, production from our new vertically integrated factory, we expect incremental revenue to drive earnings per share given the scalability of our operating model. With that, Phil will provide an overview of recent market developments, and then Patrizio and Phil will take your questions. I ask that you limit yourself to one question and a related follow-up, so that we can respond to as many of you as we can in limited time available. If you have more than one topic to address, please get back in the queue. Phil?
