After which, Phil will review recent market developments and Patrizio, Phil and I will take your questions. In my remarks, I will focus mostly on the sequential quarterly changes for P&L and balance sheet items, and refer your to our press release or upcoming Form 10-Q for additional information. As stated in today's press release, Vicor recorded a total revenue for the first quarter of $97.8 million, down 7.3% sequentially from the fourth quarter of 2022 total of $105.5 million, but up 10.8% from the first quarter of 2022 total of $88.3 million. Advanced Products revenue declined 19.3% sequentially to $51.3 million, while Brick Products revenue increased 10.9% sequentially, to $46.5 million. Shipments to stocking distributors increased 4.1% sequentially and 43.3% year-over-year. The decline in Advanced Products revenue was due primarily to constraints at our outsourced manufacturing partner. Exports for the first quarter decreased slightly on dollar basis, but increased sequentially as a percentage of total revenue to approximately 64.3% from the prior quarter's 59.8%. For Q1 Advanced Products' share of total revenue decreased to 52.4%, compared to 60.2% for the fourth quarter of 2022, with Brick Products share correspondingly increasing to 47.6% of total revenue. Turning to Q1 gross margin, we've recorded a consolidated gross profit margin of 47.6%, which is a 100 basis point increase from the prior quarter. While lower sales volume pressured gross margins, we did benefit from an improvement in the gross tariff rate as a percentage of revenue. During the quarter we recovered approximately $3 million in duty drawback of previously paid tariffs. We continue to work to reduce overall tariff expense and recover previously paid duty drawback. I'll now turn to Q1 operating expenses. Total operating expense decreased 12% sequentially from the fourth quarter of 2022 to $36.1 million. The sequential reduction was primarily due to a reduction in legal fees. The amounts of total equity-based compensation expense for Q1 included in cost of goods, SG&A and R&D was $486,000, $1,520,000 and $811,000 respectively, totaling approximately $2.8 million. For Q1, we recorded operating income of $10.4 million, representing an operating margin of 10.7%. Turning to income taxes, we recorded a tax provision for Q1 of approximately $1.1 million, representing an effective tax rate for the quarter of 9.2%. Net income for Q1 totaled $11.2 million, GAAP diluted earnings per share was $0.25, based on a fully diluted share count of 44,907,000 shares. Fully diluted EPS increased approximately 39% sequentially, compared to $0.18 in the fourth quarter of 2022, and more than doubled from $0.11 per share earned in the same quarter a year ago. Turning to our cash flow and balance sheet, cash and capital cash equivalents totaled $192.9 million in Q1. Accounts receivable net of reserves totaled $61.1 million at quarter-end with DSOs for trade receivables at 35 days. Inventories net reserves increased 5.9% sequentially to $107.4 million. Annualized inventory turns were 2.1, operating cash flow totaled $10.1 million for the quarter. Capital expenditures for Q1 totaled $10.1 million. We ended the quarter with a construction in progress balance primarily for manufacturing equipment of approximately $36 million and with approximately $13 million remaining to be spend. I'll now address bookings and backlog. Q1 book-to-bill came in below one and with one year backlog decreasing 10.9% from the prior quarter, posing a $271.3 million. Turning to our factory expansion. As expected, we recently received the final pieces of equipment necessary to complete vertical integration of our new chip fab. During the month of May, our manufacturing team will conduct pilot runs using this equipment. Through July, we expect to complete manufacturing qualification of a vertically integrated chip fab and then commence volume production. While there will still be some outsourced processing, in Q3, we expect to be vertically integrated across all of the key process steps necessary to manufacture our power modules. This marks a milestone in Vicor's history, aligning our manufacturing capacity in the first global chip fab with the breakthrough design technology Vicor has invented to deliver superior power density. As we said last quarter, we are looking forward to the substantial reduction in cycle time, improved manufacturing efficiency, and full manufacturing control that this facility will allow. And we are anxious to leverage the completion of our chip fab to provide shorter and more consistently times to our customers. Turning to the second quarter of 2023, we expect results to be approximately flat to Q1 with a potential for a modest sequential improvement in overall results, and including a moderate sequential increase in operating expense as we implement our annual merit process. With that, Phil will provide an overview of recent market developments and then Patrizio, Phil and I will take your questions. I ask that you limit yourselves to one question and a related follow up so that we can respond to as many of you as possible in the limited time available. If you have more than one topic to address, please get back in the queue. Phil?
