I'll now turn to a review of our Q2 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 second quarter of $95.4 million up 7.4% from the first quarter total of $88.8 million. Quarterly, Advanced Products revenue rose 19.7% sequentially. Product shipment growth continued to be constrained by limited component availability due to global semiconductor supply allocation issues experienced during the quarter. Brick Products revenue was basically unchanged from the first quarter. Shipments to stocking distributors rose 43% sequentially, primarily due to an increase in Brick Products shipments. Exports for the second quarter decreased sequentially as a percentage of total revenue to approximately 64% of consolidated revenue from the prior quarter 69%, primarily due to decreases in Brick Products. For Q2 Advanced Products share of total revenue increased to 43% compared to 39% for the first quarter with Brick Products share correspondingly decreasing to 57% of total revenue. We believe Advanced Products sales 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 Q2 gross margin, we recorded a consolidated gross profit margin of 52.3%. Higher volumes and improved mix contributed to higher profitability as did a reduction in cost variances and process yield improvements. Gross margin dollars rose 11.6% sequentially. Margins remained under the pressure of high tariff charges as the Q2 charge increased approximately 36% from Q1’s charge of approximately $1.4 million, primarily due to an increase in receipts of inventories subject to tariffs. Despite the increase we expect to see improvement through 2021, in part reflecting our ongoing efforts to reduce component imports from China. I'll now turn to Q2 operating expenses. Total OpEx was essentially even with the first quarter. The amounts of total equity-based compensation expense for Q2 included in cost of goods, SG&A and R&D were approximately $252,000, $780,000 and $536,000 respectively totaling $1.6 million. For Q2 we recorded operating income of $20 million, representing an operating margin of 21%. The sequential 36% increase in operating income reflects the operational leverage in our model. Turning to income taxes, we recorded a net provision for Q2 of $999,000, representing an effective tax rate for the quarter of 4.9%. Net income attributable to Vicor for Q2 totaled $19.4 million. GAAP diluted earnings per share was $0.43 based on a fully diluted share count of 44,841,000 shares. Before I turn to our financial position, just a brief update about COVID-19 and our workforce, as previously discussed, as a designated essential manufacturer using mask and practicing social distancing from the onset of the pandemic, we have continuously operated three shifts at our Andover manufacturing facility. Cases and absenteeism due to COVID are now negligible. Nevertheless, because much of the potential influence of the COVID-19 pandemic is associated with risk 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 $230.2 million at Q2, a sequential increase of 3.2%. Accounts receivable net of reserves totaled $55 million at quarter end, an increase of 15.3% over Q1 with DSOs for trade receivables, basically steady at 39 days. All balances are current. Inventories net of reserves increased 5.3% sequentially to 57.1 million. Annualized turns remained essentially the same at 3.12. Reflecting the positive operating results, operating cash flow totaled $12.3 million for the quarter. Capital expenditures for Q2 totaled $15 million. We ended the quarter with a construction in progress balance of $28 million leaving approximately $28 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. Bookings momentum continued in Q2 with book-to-bill well above 1 and with one-year backlog increasing sequentially from Q1. Turning to our outlook for the third quarter of 2021, we expect increased revenue growth in Advanced Products, offset by an anticipated decline in Brick Products revenue. We continue to address the sources of gross margin pressure and are forecasting improvement in product level profitability. Further, we do not anticipate any meaningful increases in operating expenses. While substantial further improvements in gross margin 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 the limited time available. If you have more than one topic to address, please get back in the queue. Phil?
