I'll now turn to a review of our Q4 and full-year financial performance, 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 change for P&L and balance sheet items, as well as full year-on-year changes and refer you to our press release or our upcoming Form 10-K for additional information. As stated in today's press release, Vicor recorded total revenue for the fourth quarter of $90.3 million, up 6.3% from the third quarter total of $84.9 million. Revenues for the year ended December 31, 2021 increased 21.2% to $359.4 million from $296.6 million for the prior year. Advanced Products revenue rose 18.2% sequentially, while Brick Products revenue declined 6.2% from the third quarter. Revenues for Advanced Products for the year ending 2021 increased 60.1% to $170.2 million from $106.3 million the year before. Shipments to stocking distributors increased 4.2% sequentially, and 67.4% year-over-year with year-over-year increases for both Advanced and Brick Products. Exports for the fourth quarter increased sequentially as a percentage of total revenue to approximately 71.7% from the prior quarter's 62.4%, primarily due to increases in Advanced Products. On a year-over-year basis, exports increased as a percentage of total revenue to approximately 67% from the prior year's 64.4%. For Q4, Advanced Products share of total revenue increased to 56.9% compared to 51.2% for the third quarter, with Brick Products share correspondingly decreasing to 43.1% of total revenue. Turning to Q4 gross margin, we recorded a consolidated gross profit margin of 45.2%. For the full-year 2021, gross margin improved to 49.6% from 44.3% in the prior year. While margins remain under pressure from high tariff charges, the Q4 charge did decrease by approximately 7.1% compared to Q3 to approximately $1.8 million. We continue to expect to see improvements over time, in part reflecting our ongoing efforts to reduce component imports from China. I'll now turn to Q4 operating expenses. Total operating expense increased 3.5% from the third quarter driven by increased compensation, legal, and business development expenses, for the full-year 2021 total operating expense as a percentage of revenue declined to 34.1% from 38.5% in the prior year. The amounts of total equity-based compensation expense for Q4 included in cost of goods sold, SG&A, and R&D were $261,000, $1.207 million, and $562,000 respectively, totaling approximately $2 million. For Q4, we recorded operating income of $8.9 million representing an operating margin of 9.9%. For the full-year 2021, operating income totaled $55.6 million or 15.5% of revenue, compared to $17.4 million or 5.9% of revenue in the prior year. Turning to income taxes, we recorded a tax provision for Q4 of $206,000 representing an effective tax rate for the quarter of 2.3%. The tax provision for the full-year 2021 was $176,000 representing an effective tax rate for the year of 0.3%. This was primarily due to the income tax accounting required for stock options exercised during those periods. Net income for Q4 totaled $8.9 million. GAAP diluted earnings per share was $0.20 based on a fully diluted share count of $45 million, 148,000 shares. For the full-year 2021, net income increased to $56.6 million, up from $17.9 million in the prior year. In 2021, fully diluted earnings per share more than tripled from the prior year, increasing to $1.26 from $0.41 in the prior year. Before I turn to our financial position, just a brief update about COVID-19 in our workforce. As previously discussed, as a 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. Cases and absenteeism due to COVID-19 are now negligible. 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 performances or when such influence might occur. Turning to our cash flow and balance sheet. Cash equivalents and short-term investments totaled $227.6 million at Q4, accounts receivable, net of reserves totaled $55.1 million at quarter's end, with DSOs for trade receivables basically steady at 41 days. All balances are current. Inventories, net of reserves increased 6.2% sequentially to $67.3 million. Annualized turns remained unchanged at 2.9. Operating cash flow totaled $14.2 million for the quarter. Capital expenditures for Q4 totaled $16.8 million. We ended the quarter with a construction and progress balance of approximately $36 million, leaving approximately $35 million scheduled to be spent through the year, primarily for manufacturing equipment. Our factory expansion project is proceeding on schedule and on budget, and on January 27th, we received the certificate of occupancy. I'll now address bookings and backlog. Q4 book-to-bill came in well above one, with one-year backlog increasing 17% from the immediately prior quarter, and up more than twofold from the same period last year. Turning to the first quarter of 2022, our practice continues to be not to provide specific quarterly targets. Our focus is directed at bringing our in-house production online in the coming months so that we can fully support the customer base that is driving demand for our products. We continue to work on improvements 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, Phil and I will take your questions. I ask that you limit yourselves to one question and a related follow-up so 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.

Thank you, Jim. Q4 was once again characterized by strong bookings for Advanced Products with high-performance computing customers, and with anticipated lower legacy product bookings. Orders for legacy products in regions other than China remained strong. On the advanced products front, the strong bookings growth trajectory for our high-performance computing business is expected to continue, with both increased demand from major customers and new opportunities in design activity continuing at both existing and new customers. Established OEMs and several well-known and well-funded AI startup companies that introduced initial relatively low current AI platforms are now planning AI-A6, with currents approaching 1,000 amps and a turn to Vicor's lateral and lateral vertical power solutions. Our customer portfolio in high-performance computing continues to grow. And we're ready with new Generation 5 technologies in control, silicon, and components to continue our advances in power density, current density, efficiency, and transient response, which are all critical to high-performance AI applications. Our Gen5 point of load products incorporating several major performance advances will be introduced in Q3 this year to early lead customers. The demand for high-density power delivery solutions continues unabated across all of our target markets, with power systems engineers turning to Vicor's modular power solutions to solve their toughest design challenges. Our work in the past three years in the broad industrial marketplace to find new growth applications is beginning to pay off. Due to the rapid electrification and autonomy trends within both existing and emerging industrial markets, we have identified an additional $2.5 billion of available market in the next five years, across market segments such as light electric vehicles, robotics, battery test equipment, and UAVs. Our opportunity pipeline currently stands at $250 million for these new high-growth applications. Our automotive business development success in 2021 confirmed our confidence that the automotive market presents a significant growth opportunity for Vicor power modules, and our place as a major future supplier of power modules to the automobile and truck industry. Our directed supplier strategy with leading OEMs has been very successful with three production design wins and now ten collaboration products with major OEMs on technology and power module-based system evaluations. Our aerospace and defense business strategy is undergoing a refocusing on four key growth markets. In one of these markets, satellite communications, we have made advances with new customers and our opportunity pipeline outside of our lead customer, Boeing, is beginning to grow. We are excited for what lies ahead of us in 2022 and beyond given the major dislocations occurring in numerous large-end markets, assistant power levels increase, and electrification and autonomy drive the demand for higher performance power delivery networks. Major customers across our target markets clearly see the significant benefits of moving to higher voltages and away from discrete-based custom power system solutions, and towards high-density modular power solutions from Vicor. Key to maximizing our growth opportunity will be achieving and maintaining operational excellence across our entire company. Initiatives launched in Q2 of last year are now well underway with multiple cross-functional teams focusing on seven pillars of continuous improvement, ranging from customer centricity to talent retention and acquisition. Our commitment to vertical integration of our manufacturing processes, and expanding our American base of operations is also a key success factor to achieving operational excellence. As Jim noted earlier in his prepared remarks, our new facility is approaching completion and will be operational in Q3 of this year, with a ribbon-cutting opening ceremony on April 26th. That concludes my remarks and Patrizio, Jim, and I will now take your questions. Okay. Operator, we're ready for questions now.

Alright. Thank you. Everyone, if you wish to ask a question, please press the appropriate keys on your phone keypad. All questions will be answered in the order received. The first one is coming from the line of John Dillon. Please proceed. Your line is open now.

Hi, guys. Congratulations on the bookings. They look really good. I did have a question on the new factory. I thought production would be starting this quarter. Can you give us a little more color on what's happening with the new factory?

Yes. Regarding start-up production in the new wing, we're actually expecting next week to start production on the new line with the capacity of one panel, which is multiple modules per minute. That's the portion of the expansion with a shorter cycle time to fruition than other portions that deal more with package technology that is key to vertical integration. So that equipment will be in place, and two cranes will be there on Tuesday, lifting additional equipment that is getting installed. We have tens of millions of dollars of equipment going in, and it's going to start going through qualification runs later this quarter and into next quarter. Some of the processes are going to be operational in the second quarter, but to be clear, as suggested by Jim earlier, a full vertical integration will be in July.

Got you. So we'll still see some increased production then for the next couple of quarters, I would imagine?

Well, in certain areas, we are looking at significant increases in production again starting next week. With respect to some of the process steps involved in the ship or convert to house in package technology, we're going to have access to some of the processes that start in Q2. But again, for complete vertical integration, it will be in July.

Got you. But can we expect to see total revenue start to increase quarter after quarter? I am asking if the supply chain constraints, along with the additional new factory, will result in an increase in revenue or a continuation of revenue growth.

So with Q4, we achieved significant increasing throughput, particularly with respect to Advanced Products, which was about 18% sequential from the third quarter. That still fell short of our expectations for a combination of reasons, some lingering challenges on the component availability side, as well as significant challenges with respect to some of the package process steps that are outsourced. Now, we brought on another partner, which provided some relief in the last month. But as suggested in the prepared remarks, we're really counting the days at this point to the other parts of the second quarter and for full integration. The beginning of our Q3 will provide us with the control we need to have in order to achieve the stability we expect. Unfortunately, that predictability wasn't there in Q4. Just to be clear, that level of predictability isn't going to be there in this quarter either. I think the access to capacity with respect to some of the process steps gives our operations team more flexibility regarding getting their job done. But it's been very challenging for them, both because of the tight supply chain and challenges with respect to some of the processes. Just to give you a little bit of context, in Q4, we confronted a 5X price increase on some of these process steps. So it's been a difficult environment, and we're eager to complete the selection of the equipment, which is progressing well, and then get the benefit of having control of our destiny once all the equipment is ready for fabrication.

Got you. So based on that, can we get a sense of whether you delivered $90 million in revenue this fourth quarter? Will we see an increase in the first and second quarter?

I turn it back to Q4. We fell short of our target, even though earlier in the quarter we thought we were going to see a higher step-up in Advanced Products revenues. We believe that until we are in control of our destiny, we cannot provide guidance on the level of improvement sequentially. We don't want to give surprises, one way or the other. We do have a lot of backlog and numerous customers looking for more allocation on key products. You can be sure that our operations team is working extremely hard to bring this about, even before we establish the level of control we need.

As I said earlier in the call, it's Jim here, we are just not going to offer up specific guidance. What we've included really needs to have control over our own destiny, and we're probably weeks away from having that visibility and sense of control.

Yes. We are gaining greater control of our destiny. Going back to the component availability issues, especially on the semiconductor front, we may progress. We have bigger allocation, but that landscape is still full of mines. As an example, late last year, we faced an end-of-life on certain components and then the vendor didn't follow through on our last time buy. So we're dealing with complexities in our supply chain that make predictability hard, aside from the lack of vertical integration in our manufacturing processes.

Got it. I understand that. Thank you, and I will get back in the queue. Thank you so much.

Thank you, Jim. Q4 was once again characterized by strong bookings for Advanced Products with high-performance computing customers, and with anticipated lower legacy product bookings.
