Operator, Operator
Welcome everyone to today's webinar entitled, Vicor Earnings Results for the Fourth Quarter Ended December 31, 2023. My name is Yono and I'll be your operator for today. I would like to advise all parties this conference is being recorded. And now I would like to hand it over to Jim Schmidt, Chief Financial Officer. Please go ahead.
Jim Schmidt, CFO
Thank you. Good afternoon and welcome to Vicor Corporation's earnings call for the fourth quarter and the year ended December 31, 2023. I'm Jim Schmidt, Chief Financial Officer, and I'm in Andover with Patrizio Vinciarelli, Chief Executive Officer; and Phil Davies, Vice President, Global Sales and Marketing. After the markets closed today, we issued a press release summarizing our financial results for the three months and the year ending December 31. This press release has been posted on the Investor Relations page of our website, www.vicorpower.com. We also filed a Form 8-K today relating to the issuance of this press release.

A webcast replay of today's call will be available shortly on the Investor Relations page of our website. 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 for our upcoming Form 10-K for additional information. As stated in today's press release, Vicor recorded total revenue for the fourth quarter of $92.7 million, down 12.2% from the third quarter total of $107.8 million, and down 12.2% from the fourth quarter total of $105.5 million. Revenues for the year ended December 31, 2023, increased 1.5% to $405.1 million from $399.1 million for the prior year. Advanced product revenue declined 20.1% sequentially, while brick product revenue declined 7% from the third quarter. Revenues for advanced products for the year ending 2023 decreased 8% to $223.9 million from $243.3 million the year before. Revenues for brick products for the year ending 2023 increased 16.3% to $181.2 million from $155.8 million the year before. Shipments to stocking distributors decreased 23.5% sequentially but increased 46.9% year-over-year. Exports for the fourth quarter decreased sequentially, as a percentage of total revenue to approximately 56.5% from the prior quarter's 62.8%. On a year-over-year basis, exports decreased as a percentage of total revenue to approximately 63.1% from the prior year's 67.6%. For Q4, the advanced product share of total revenue decreased to 50.4%, compared to 54.2% for the third quarter, with the brick product share correspondingly increasing to 49.6% of total revenue. Turning to Q4 gross margin, we recorded a consolidated gross profit margin of 51.1%, approximately 0.7% less than the prior quarter. For the full year 2023, gross margin rose by 5.4% to 50.6%, from 45.2% in the prior year. A number of factors contributed to the year-on-year increase in gross margin percentage, including improved sales mix, increased royalty income, reductions in supply chain costs, and lower freight and tariff costs. I'll now turn to Q4 operating expenses. Total operating expenses, including litigation expenses, decreased 0.4% from the third quarter. For the full year 2023, total operating expenses as a percent of revenue decreased to 37.9%, from 38.4% in the prior year. The amounts of total equity-based compensation expense for Q4 included in cost of goods, SG&A, and R&D were $680,000, $1,895,000, and $1,007,000, respectively, totaling approximately $3.6 million. For Q4, we recorded operating income of $7.3 million, representing an operating margin of 7.9%. For the full year 2023, operating income totaled $51.4 million, or 12.7% of revenue, compared to $27.2 million, or 6.8% of revenue in the prior year. Turning to income taxes, we recorded a tax provision for Q4 of approximately $1.9 million, representing an effective tax rate for the quarter of 18.2%. The tax provision for the full year 2023 was approximately $6.6 million, representing an effective tax rate for the year of 11%. Net income for Q4 totaled $8.7 million. GAAP diluted earnings per share was $0.19, based on a fully diluted share count of 45,017,000. For the full year 2023, net income increased to $53.6 million from $25.5 million in the prior year. In 2023, fully diluted earnings per share rose from the prior year, increasing to $1.19 from $0.57. Turning to our cash flow and balance sheet, cash and cash equivalents totaled $242.2 million at Q4. Accounts receivable net of reserves totaled $52.6 million at quarter end. With DSOs for trade receivables at 40 days, inventory's net of reserves increased 1.9% sequentially to $106.6 million. Annualized inventory returns were approximately flat sequentially at 1.92. Operating cash flow totaled approximately $22.1 million for the quarter. Capital expenditures for Q4 totaled $7.7 million. We ended the quarter with a construction and progress balance, primarily for manufacturing equipment of approximately $17.7 million, with approximately $17.3 million remaining to be spent. It's worth noting that in Q4, we accrued approximately $13 million as an investment tax credit related to the CHIPS Act for equipment installed in our vertically integrated ChiP fab. I'll now address bookings and backlog. Q4 book-to-bill while improving sequentially came in below 1, with one-year backlog decreasing 8% from the prior quarter, closing at $160.8 million. Turning to the first quarter and the full year, 2024 is a year of uncertainty and opportunity. As of today, the year's outcome in terms of top line and bottom line is subject to a relatively wide range of scenarios. Given the wide range of possible outcomes, we are unable to provide quarterly guidance until we are further along resolving uncertainties and capitalizing on opportunities. 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 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 Davies, Vice President, Global Sales and Marketing
Thank you, Jim. As Jim covered in his update, our book-to-bill ratio was still below one in Q4, mainly due to low booking levels in our HPC business and the Automatic Test Equipment segment of our industrial business. In HPC, Q4 bookings were lower than expected as we turned down deals inconsistent with our long-term OEM licensing strategy. The license gives OEMs access to alternate sources of supply for products covered by Vicor IP from otherwise infringing suppliers, enabling current and future-gen AI processors to achieve higher performance. The OEM license provides access to game-changing technology from a single-source innovator through multi-source supply chains. The OEM license avoids the risk of exclusion orders, and it respects the IP of American innovators and manufacturers. In anticipation of market needs, Vicor was the first to develop key technologies, control systems, topologies, components, and packaging for 48-volt high-current processor power delivery networks. Those market needs are clearly with us now in the advent of Gen AI, machine learning, 48-volt rack power systems, and vertical power delivery. As evidenced by progress already made in forcing our IPs to NBMs, our message to the market is clear. The OEM license gives you open-ended access to superior power system technology. It provides continuity of supply for otherwise infringing servers and AI processors. Additional customer engagements in Q4 confirm that Gen AI and network processor platforms will require significantly higher current density and vertical power delivery. Our investment in the world's first chip foundry and our 5G product line once again anticipated these future AI power system requirements, uniquely positioning us to expand our share of the AI power system market. We are getting ready to deliver evaluation systems, models, tools, and samples to lead AI processor customers. On other market and customer fronts, our new product and applications pipeline continues to grow, creating both near-term and future demand to fill our vertically integrated foundry. In our automotive business, collaborations that were initiated with OEMs in 2021 have started to move into production with low-volume platforms as we ramp our automotive qualification, manufacturing, and OEM relationships through early learning cycles. Momentum is picking up in both the mild hybrid and BEV market for Vicor's technology in response to the 48-volt Zono architecture first conceived and patented by Vicor and recently promoted by Tesla. Collaborations with larger OEMs on higher-volume platforms are gaining momentum with visibility to production dates in the coming years. We will be participating at WCX in Detroit once again this year, with four technology papers that will showcase our technology and power system value propositions for 800-volt and 48-volt power modules. In our other business units, we continue to see stronger demand in our broad industrial, aerospace, and defense markets for both large OEMs and smaller customers who purchase through our channel partners. Customer visits from our top 100 accounts have also continued to view and audit our new ChiP fab as we now ramp production of advanced products. Thank you, and with that, we will now take your questions.
Operator, Operator
Good afternoon, everyone. The first question is coming from Jon Tanwanteng. Please go ahead. Your line is unmuted now.
Patrizio Vinciarelli, CEO
Hello, Jon.
Jim Schmidt, CFO
Yes, go ahead, Jon.
Jon Tanwanteng, Analyst
Thank you for taking questions. To clarify, did you turn down data center or HPC deals because of issues related to XPU power due to NBM licensing, or were they simply NBM deals? Can you help me understand the concerns surrounding the technology? Were they economic issues or purely related to the IP?
Patrizio Vinciarelli, CEO
Yes, so you're not going to have an opportunity to analyze it, because we're not going to get into specific details. But I think it's important to understand that we have a clear vision of where we're going. We're sticking to that vision as events unfold on a variety of fronts related to asserting our patents concerning the NBM and other developments. The marketplace, needless to say, is driven by a complex set of forces. On the one hand, there is a drive to multi-sourcing, particularly for very high volume applications. But at the end of the day, there is also an overwhelming need for higher current density solutions and vertical power delivery. These are areas where Vicor is a pioneer and has established a strong beachhead of IP and opportunities that we're going to seek to realize through the right mix of licensing to facilitate multi-sourcing as needed, where needed, and participation directly with modular solutions from a new hub.
Jon Tanwanteng, Analyst
Okay. Fair enough. And I understand. Is this something that can be resolved in the near term as you negotiate more? Is this something that will take the assertion of your litigation strategy and the completion of that to complete?
Patrizio Vinciarelli, CEO
Well, so as implied by Jim's point in his remarks regarding the uncertainty and opportunity that characterizes the next quarters, we can't make that prediction. And we don't want to make that prediction, because we want to retain the flexibility needed to implement our long-term strategy. So, we're not going to go out on a limb in terms of predicting when things will happen. I can tell you that my expectation is that we're going to be successful. We're going to be successful with our first litigation with respect to asserting the NBM patents. We're doing very well in that regard and we're far along with respect to that process. We're also going to fill the factory in due course. So, we're very confident in our strategy, very determined to enable it, and patient if need be in order to bring it about.
Jon Tanwanteng, Analyst
Understood. Thank you. I'll jump back in the queue.
Operator, Operator
The next question is coming from Quinn Bolton. Please go ahead. Your line is open now.
Patrizio Vinciarelli, CEO
Yes. Go ahead, Quinn.
Quinn Bolton, Analyst
Okay. Great. I guess I understand you don't want to provide a lot of detail. But I just want to try to make sure I understand sort of the range of alternatives. You said you're turning down deals for NBMs. It sounds like from your opinion or perspective, many of the competing NBMs may infringe your patents. And so if you turn down the deal, what's the alternative for the customer? They just use infringing NBMs until you have asserted those patents, or do competitors license your patents?
Patrizio Vinciarelli, CEO
So, we have existing proof of a business model that works quite well. We have a significant licensee that has been sourcing NBMs from an otherwise infringing source by virtue of an OEM license with us. And that's, again, part of our overall strategy concerning balancing a variety of needs and opportunities for our customers, the market at large, and ourselves with due respect for intellectual property as well as the needs of the customers, that in some relevant instances do have an overwhelming need for multi-phase sources.
Quinn Bolton, Analyst
And I guess a second question just sort of around the IT front. I know we've got the APEX show next week. A lot of papers at that conference will be talking about vertical power delivery. I think Monolithic Power, Analog Devices, and NBM have all talked about vertical power delivery from the multi-phase perspective. Can you give us your latest thoughts, Patrizio? Just where do you feel the industry is in terms of adopting vertical power delivery? And to the extent that multi-phase competitors are moving in that direction, is that an area where you may have to assert your patents on that front? Because I know you've been talking about vertical power delivery now for probably three-plus years? Thank you.
Patrizio Vinciarelli, CEO
Yes. So vertical power delivery means certain specific things. One of them with what we call first-gen VPD, the stacking of what we call a multi-cell converter. The multi-cell converter can be a vehicle car multiplier. It can also be a multi-phase solution. It doesn't matter. It falls within our IP in the context of a stack solution with certain attributes. So, we pioneered that concept. It's been implemented to a limited extent by competitors whose solutions lack robustness, scalability, and cost-effectiveness. They suffer from all the traits of first-generation technology that in many respects is immature and not scalable. Without question, it's going to become somewhat more mature and somewhat more scalable as initially conceived by Vicor. But still handicapped in a variety of fronts, including the intellectual property front. With our 5G technology, we are on what we call a second generation of VPD, which is much more scalable, much more cost-effective, much lower profile, much more efficient, and which we believe before too long will enable much more advanced solutions.
Quinn Bolton, Analyst
Understood. Thank you.
Operator, Operator
The next question is coming from John Dillon. Go ahead.
John Dillon, Analyst
Can you hear me?
Jim Schmidt, CFO
Hi, guys. It's pretty faint, John.
Patrizio Vinciarelli, CEO
Yes, I don't think we can hear you.
John Dillon, Analyst
Okay. So I mean just previous remarks, you were talking about some IP that you have in the automotive. Then right after that, you said it was promoted by Tesla. Can we infer from that that Tesla might be a customer of yours soon?
Patrizio Vinciarelli, CEO
So I heard the word Tesla and 48-Volt and IP.
Jim Schmidt, CFO
Okay. Is Tesla going to be a customer soon, I think is what John was asking?
Patrizio Vinciarelli, CEO
So, we're not going to make comments about specific companies or potential customers. But I will mention that as in other fronts, Vicor was a pioneer with respect to the concept of using bus converters within automotive power distribution. So that's an area of intellectual property that may come to fruition at some point in time. As you can imagine, or as implied by earlier comments, there's no shortage of opportunity. As of now, we're very focused on bringing to fruition our NBM initiative, but it is part of a very broad campaign which again is part of a very comprehensive strategy to enable a more efficient, scalable, and fair market when it comes to advanced power system technology.
John Dillon, Analyst
The other thing I wanted to congratulate you on the bookings. It looks like from the press release, it's headed up and it looks like your bookings are up about $13.5 million from the previous quarter. So I'm just wondering, Bill, do you expect this trend to continue? I don't want any specifics, but can we expect the trend to continue throughout the year?
Patrizio Vinciarelli, CEO
Yes, so I don't think that the word trend applies or the United States of America, or whatever you want to call it, to events unfolding over the next few quarters. Because as discussed earlier, I think we should all be clear with respect to this, there is a wide range of scenarios. And because of that, individual events could impact bookings, top line, and bottom line from one quarter to the next in ways that are frankly unpredictable. To say there is a book stop at the low end, but we're not going to quantify what that is. There is limited downside, I would say. There is quite a bit of upside, but that upside is hard to predict in terms of the timing.
John Dillon, Analyst
I get that. I understand that. So this last quarter you alluded to, last conference call you alluded to, a sizable upside. It sounds like that sizable upside is still out there, but it's not predictable at this time?
Patrizio Vinciarelli, CEO
That's right. I will say that the cumulative impact over time is more predictable than instant contributions that may happen sooner or later. So fundamentally, the strategy, as it has always been, is to take a very long-term view. We're not, I know we're in the context of reporting to the financial markets, but we're not, to be perfectly honest with you, making decisions based on what may look particularly good in any one quarter. We are making decisions based on what we think is in the long-term interest of the shareholders, again, balancing the various factors at play in a comprehensive strategy.
John Dillon, Analyst
Got it. I'll get back in the queue. Thank you. Thank you very much.
Operator, Operator
The next question is coming from Quinn Bolton. Please go ahead. Your line is open.
Quinn Bolton, Analyst
Okay. I guess I wanted to follow-up on John's question. There are obviously a range of scenarios you're talking about, but to the extent the upside scenario plays out, I assume that those are likely either NBM or fourth generation or more, hopefully fifth generation design wins. How quickly could you ramp that business? I mean, I think in past quarters, you've talked about manufacturing lead times that are about six months. So, would it take a couple of quarters, to sort of start to realize some of those upside opportunities? Is that the right kind of way to think about the timing, to the extent the upside case begins to play out? And then I've got a follow-up?
Patrizio Vinciarelli, CEO
So, we have capacity in place now. We could, in the next quarter, the quarter after that, manufacture more subject to, obviously, material procurement lead time. Then we would, based on what we stand currently in terms of the bookings and backlog situation. Just as a reminder, the issues and challenges of yesteryears, when we didn't have a very integrated factory, we were dependent on outside sources of supply for critical process steps, are gone. Those are no longer challenges. Now we face a different type of challenge that, again, is resulting from sticking to a strategy that has us balance a variety of considerations. But as I think back about the starting challenges, I feel that with the establishment of our first chip foundry, we are in a position we've never been in, in answer to your question regarding scalability. We have a level of scalability that Vicor never had. We manufacture advanced products in panels, which are akin to wafers, and in our chip foundry, we can make a very, very large quantity of panels. We have a lot of capacity. Needless to say, there's still going to be a lead time. There's no set function to be had. But demand can be addressed with supply within a relatively short cycle time.
Quinn Bolton, Analyst
Thank you. Patrizio, the follow-up question is, in the current latest generation GPU market, one of the multi-phase vendors that has pretty high share recently had some testing issues. And I'm wondering if you've had any discussions sort of since that event that might lead you to believe that any of the large AI processor GPU vendors, one, are now more open to having multiple sources of supply. And particularly, has this event potentially raised some concerns about the multi-phase approach in general, given that you've got one or more controllers that may have to control 20, 30, 40 phases? You know, have you seen anything coming out of that event that may benefit Vicor, either in the near term or the longer term? Thank you.
Patrizio Vinciarelli, CEO
So multi-phase systems have challenges, and those challenges get compounded in a VPD type of solution. The underlying primary challenge of multi-phase is that it is a lower current density type of solution. It involves the averaging down of a voltage to step up the current through switching elements that need to support a much higher voltage withstand and do so reliably and without a well-safe operating area. Then with a Vicor current multiplier, which can, in effect, multiply current and do so much more efficiently, with lower voltage semiconductors without commensurate safe operating area challenges. There are benefits there to do, in particular, just to give you some examples, with the fact that without our proprietary approach, there is no multi-phase. Each one of which, should it fail, could take a GPU or the AI processor with it, as it can fail with a top switch short, which could happen with any of a larger multiplicity of phases. So, we have many, many advantages in terms of the power distribution architecture, the topology, the type of components that these solutions require, which are fundamentally different. But then getting back to the VPD side of things, with a multi-cell approach involving a multiplicity of phases as opposed to a multiplicity of current multipliers, as we have, you have, in effect, the compounded challenge of a power conversion topology, back-converter, which is nearly low current density, compounded by the mechanical challenges with first-generation VPD of stacking this multi-cell topology with gearboxes or capacitive layers that are required in order to provide filtering and dynamic response. And only to get too technical with this, getting to the punchline, VPD, first-generation VPD implemented with multi-cell solutions in the form of multi-phase is very, very challenging, costly, not truly scalable, immediately handicapped, and in need of an overhaul. We're not seeing, based on our visibility, it being scaled up with the level of load effect rates and manufacturability that larger EMs would expect to have.
Quinn Bolton, Analyst
Got it. Thank you.
Operator, Operator
The next question is coming from Alan Hicks. Please go ahead. Your line is open.
Unidentified Analyst, Analyst
Hear me?
Patrizio Vinciarelli, CEO
Yes.
Unidentified Analyst, Analyst
Okay. It sounds like the factory is virtually complete, although I know you have some more build-out. Can you confirm that?
Patrizio Vinciarelli, CEO
Yes. We have a bar graph that we review every week. It used to be yellow and red. It's now all green in the sense that the green sourcing of yesterday, which was yellow and red, has become a green source that has made handover in our Berkeley Integrated Facility. Those bars are rising from week-to-week. So, we are doing well in that regard. To your point, we're not fully done with bringing in equipment. There are still some additional equipment that is equipment we committed to that are going to add some additional capacity and process capability that's due in in the next several months. But the core capability of, in effect, building up the other layers of our unique converter housing package, type of technology, two panels, again, the wafer analogy when it comes to high-density power converter modules, that capability is in place. And we're using it and we're setting it up.
Unidentified Analyst, Analyst
Okay. So you would say lead times are coming down?
Patrizio Vinciarelli, CEO
Well, so what is going on in? What has been going on, in particular, within the last quarter is that the mix has changed, right? With the different backlog situation and the need to utilize capacity to address some of the backlog that have been overdue, our mix has changed. And that places its own constraint on thought capacity. And that's frankly the reason why we fell short somewhat of our internal target in terms of top line within the quarter. It wasn't that we didn't have enough backlog. It's just that there was a bit of a mixed challenge because instead of making lots of modules of a certain kind, we had to make a somewhat smaller quantity or variety of different things, right? So that's a factor with respect to thought capacity. And it was a factor in particular with respect to top line in the last quarter.
Unidentified Analyst, Analyst
Okay. And going forward, you're capable of building the 4G products lateral, vertical, and so on. And what's the interest in 4G?
Patrizio Vinciarelli, CEO
I'm sorry, what is the interest in 4G?
Unidentified Analyst, Analyst
Yes.
Patrizio Vinciarelli, CEO
Yes. And frankly, I'm not thinking about 4G. I'm thinking and the executive team is very much focused on making sure that we bring 5G to completion and get demo system boards out to customers, tools, and begin that scale-up.
Unidentified Analyst, Analyst
Okay. Thank you very much.
Operator, Operator
The next question is coming from Jon Tanwanteng. Please go ahead. Your line is open.
Jon Tanwanteng, Analyst
Hi. Thanks for the follow-up. I was wondering if your expectations for the automotive applications have changed at all, just given the shift in automotive sentiment, where maybe hybrids are a little bit more back in fashion versus pure EVs and how that plays out to your 48-volt technology?
Phil Davies, Vice President, Global Sales and Marketing
No. Hi, John. It's Phil. So no, the market is sizable for us as a new entrant, of course. I mean, there's still millions of BEVs and mild hybrids out there for us to go after with their 800-volt or 400-volt battery technology. And what we're seeing at the moment that's actually quite interesting is that we have powertrain solutions that go from 800 to 48 or 800 to 12. We have an onboard charger platform that is incredibly power-dense and is getting a lot of interest in the market with 800-400-volt bidirectional conversion. And so, what we're seeing recently actually are different applications, like for example converting a condenser or an active suspension system, or a seat heater from an 800 or 400-volt battery down to 48 volts as 48 volts starts to take hold in some of these electromechanical applications. So, we've seen a lot more of that in the last, I would say, the last two quarters. And that's exciting for us because those are relatively high-volume applications, like the active suspension, for example, is two to four modules per vehicle. So we're encouraged about the continued progress in automotive. And the application spread is actually increasing for us.
Jon Tanwanteng, Analyst
Understood. Thank you. And then second, just wanted to go back to the issues with IBM and the IP. As you assert your intellectual property there, is there a risk that it deters potential customers from pursuing designs or closing deals on fifth-generation VPD technology? Or do you view them as mostly ring-fenced here? You know, I'm just thinking that, you know, maybe if you're pursuing this path and the demand is out there for all these AI processors, maybe the customers might settle for something that's less than perfect just to meet the demand that they see?
Patrizio Vinciarelli, CEO
So I guess the way I would view this is that in terms of encouraging or discouraging OEMs from doing business with us, I would expect that OEMs make these decisions based on their considered interest, right, which involves access to competitive technology. Because to say if they are foreclosed from a power system technology that their competitors have, they are in a challenging competitive position of their own. And so, to the extent that Vicor provides access to enabling power system technology, whether it's VPDs, particularly second-generation VPD, or high-current density solutions, customers come to us because they realize we have those capabilities which the commodity pack or multi-phase does not have. Now, the enforcement of the IP is a necessity. IP needs to be respected. We can't have a market in which OEMs, particularly large OEMs, wish to commoditize a proprietary product covered by a lot of innovation and patents, as is the case for the NBM and other unique vital capabilities. So we need to make the investment necessary in getting the respect that the intellectual property deserves. Our first action in this regard is an action of the International Trade Commission. We're now more than halfway through that process. We are going to be at trial at the end of April, and thus far, we're winning on just about every key decision that has been made to date. So I'm very encouraged with respect to the outcome. We're very focused on bringing that to a successful conclusion later this year.
Jon Tanwanteng, Analyst
Got it. When do you expect the final decisions to be made there? And what are you expecting the legal costs to be just on a runway basis as we get there?
Patrizio Vinciarelli, CEO
So the ITC will render its decision by, I think, the very beginning of October. The trial is at the end of April, beginning of May. Cherry-blossom time in Washington, D.C. Good time to be in Washington.
Jon Tanwanteng, Analyst
Got it. And the cost, the legal expenses associated with that?
Patrizio Vinciarelli, CEO
It's significant, but not nearly as significant for our opponents, because of how we structure the RDO with law firms that work with us as partners. We have a common goal and a common set of interests.
Jon Tanwanteng, Analyst
Got it. Okay. Thank you.
Operator, Operator
The next question is coming from John Dillon. Please go ahead. Your line is open.
John Dillon, Analyst
Hi, guys. Thanks for the follow-up. Patrizio, your cash keeps increasing even after you're investing in building a new factory. So I'm wondering, are you saving the cash for building a multiplicity of ChiP fabs or are you considering stock buybacks for that cash?
Patrizio Vinciarelli, CEO
Building more fabs or a stock buyback isn't it? Yeah. So I'm sorry, I couldn't understand all of what you said. But regarding more fabs, we first have to fill the existing one, right? And the existing one, which we have represented to have a capability of nearly $1 billion, based on some of the advances we made with our 5G technology, is not expected to be able to support considerably more than that level of yearly revenues. So, we got a while to go before having to invest in a second fab.
John Dillon, Analyst
What about stock buybacks?
Patrizio Vinciarelli, CEO
Well, we're focused on a variety of opportunities at this point in time. And frankly, that's not being on my end of the screen. But it may get on the screen, and if and when that happens, we'll find out when it happens.
Jim Schmidt, CFO
Okay. Sure. So what are we using the cash for? Well, I think at this point, it is the case, John, that one very favorable thing that occurred in the last couple of quarters is a couple of quarters of greater than $20 million per quarter of operating cash flow. So there is a sense now that with royalties and other parts of the P&L and the factory internalized and no more spend outside that we can be pretty efficient and very efficient, in fact, in generating cash. But let's let the cash flow grow a bit and then we'll decide as to create a revenue. Look at it.
Patrizio Vinciarelli, CEO
Yes. So we need to say we particularly in the early stage of our IP campaign, want to be in a very strong financial position, right? And there are several reasons with respect to being able to invest in the campaign to extend the necessary for as long as it takes to achieve the goals. That's our top priority. That's most important strategically. Going back to your question, let's say we could buy back 5% or 10% of our float. That opportunity, relatively speaking, pales relative to the opportunity to double the value or do more than that by succeeding at the standard in the mission. And that's our focus.
John Dillon, Analyst
Got you. And, Phil, can you just give us a brief update on your design wins? How they're going? Where do you see them coming up?
Phil Davies, Vice President, Global Sales and Marketing
As I mentioned in my remarks, John, the pipeline is continuing to grow. I mean, as I talked about, we're focused as a strategy on 100 customers. We've identified those 100 customers with about a $6 billion SAM for Vicor. We're very focused on those top 100 with account managers on every single one of them. And every single one of them is targeted for a set of new products that will start to release in Q4 and we'll have more in Q1 and Q2. So the pipeline is growing. We've got a very healthy growing pipeline. I'm quite confident in all four business units achieving their goals over the next three to four years by 2027.
Patrizio Vinciarelli, CEO
Yes. You see part of the note that this is a diversified model, right? We're not - even though there's been a lot of talk, a lot of focus, particularly from the investor community on AI for obvious reasons that center opportunities. That is one of the primary markets. It's not the only market. You heard us talk about automotive. That's an important market as well, obviously an emerging market for us. But we have two other end markets that in their own right represent opportunities. Outer space and defense, industrial market, our products have all the right traits for those applications and those end markets. And those in their own right represent the opportunity for us. If you see here, actually in the business model, it is obviously key to the overall strategy in terms of market transactions.
John Dillon, Analyst
Thank you guys very much. Really appreciate it.
Operator, Operator
The next question is coming from an attendee who joined over the phone. So I will unmute you now, but I would like to ask you to introduce yourself before you take your question.
Phil Davies, Vice President, Global Sales and Marketing
We might want to go to the next questions operator.
Operator, Operator
Sure. The next questioner also joined over the phone. So I will unmute you now. And as I asked earlier, please introduce yourself before you ask a question. Please go ahead.
Unidentified Analyst, Analyst
Okay. Hi, this is Don McKenna.
Patrizio Vinciarelli, CEO
Hi, Don. Please go ahead.
Unidentified Analyst, Analyst
All right. Can you guys hear me?
Patrizio Vinciarelli, CEO
Yes, very well. Yes.
Unidentified Analyst, Analyst
Okay. Then I was following up on John Dillon's earlier question relative to bookings. And I know you said you didn't want to project any kind of trends, but can you give a rough idea how they're running so far? You're halfway through the quarter. How they're running compared to last quarter?
Patrizio Vinciarelli, CEO
Again, setting expectations with respect to what is going to happen this quarter or next quarter is not something we're going to do because it could be misleading one way or the other. And we don't want to do that. So we want to be very honest in sharing what we characterize as challenges and opportunities.
Unidentified Analyst, Analyst
All right. Thanks.
Operator, Operator
And we have one more question from an attendee who also joined over the phone. So I will unmute you now, but please introduce yourself before you take a question.
Unidentified Analyst, Analyst
Hello? You're muted now.
Phil Davies, Vice President, Global Sales and Marketing
Yes. We can hear you.
Unidentified Analyst, Analyst
Hello?
Phil Davies, Vice President, Global Sales and Marketing
Yes, we can hear you.
Unidentified Analyst, Analyst
Hello? This is Neil Moore. General Motors announced that they're building a big plant domestically for EVs. Do you expect that you'll be selling your products to GM for this?
Patrizio Vinciarelli, CEO
So, we, not again, not talking about any specific customers. But we have really covered most of the OEMs globally with our technology. It's been part of our strategy to get the OEMs excited about Vicor technology and what it can do in their platforms, or mild hybrid platforms, and for them to really start collaborations with us and to then bring in Tier 1s. As our strategy for 2024 evolves, we're starting to work with more Tier 1s on those types of collaborations. So rather than get specific about one customer, I can say that generally, on a global footprint, we're doing very well with those collaborations and moving forward with our automotive strategy. But it's good to see the GM investment. That really is good to see.
Unidentified Analyst, Analyst
Thank you.
Patrizio Vinciarelli, CEO
If there is one more question before we close.
Operator, Operator
All right. The last questioner also joined over the phone. So I will unmute you now. Please introduce yourself before you take a question. Please go ahead. Your line is open now.
Unidentified Analyst, Analyst
Can you guys hear me?
Patrizio Vinciarelli, CEO
Yes.
Unidentified Analyst, Analyst
Okay, great. This is Richard Chan with Craig Hallam. I've been trying to connect for 45 minutes, and I'm not sure what's going wrong with this service. Looking at your 5G technology, you mentioned in your last call that you aimed to deliver models and tools this quarter. I think I was on early enough to catch the prepared remarks but didn't hear any updates on that. I'd appreciate it if you could provide an update on whether those have been delivered. Additionally, regarding your transition to volume production, you hinted that it might happen by the end of this year or early next year. What needs to take place between now and then, and how can you utilize the new facility to reassure large customers of your capacity to ramp up with high yields, high quality, and reduced lead times?
Patrizio Vinciarelli, CEO
So customers have come to visit the facility, kicked the tires as it were, and generally speaking, they've been very impressed. We had, as an example, a couple of weeks ago, the VP of operations for a company with a very unique product in the realm of AI capabilities, and he commented, having visited the factory that he'd never seen anything like that in terms of capabilities instead of the art facilities. So, the customer visits and customers being exposed to the equipment, the processes, and the systems that our team has put in place speaks volumes to the scalability, the methodology of making panels of chips as if they were wafers of semiconductor devices. Regarding 5G, we are engaged with some lead customers, including one I was referencing a moment ago and another notable one that comes to mind. That is particularly keen on our technology, and we have a schedule that has us deliver them functional samples, tools, and demo systems as we progress through Q2 and Q3 of this year. Regarding getting into production, we're going to have a pilot production for 5G in the second half of the year. In terms of revenue opportunity, this is a Q1, 2025 type of event. It's not in terms of contribution to revenue in any meaningful way a 2024 event, just to be clear.
Unidentified Analyst, Analyst
Okay, perfect. Wanted to get that confirmation. I appreciate that one. My last quick question here is there was a statement made by, I can't remember if it was either Patrizio or Phil on the last call here, about expecting a dominant share of AI power systems, I think referring to, you know, with 5G and over a period of time. I just wanted to, especially given the, you know, step down to revenues that might concern people, wanted you to reiterate if you still believe that to be the case reiterate, that that's what you think is going to happen?
Patrizio Vinciarelli, CEO
It is. It's not a dream. It's a vision that is rooted in hard numbers. The current density, the amps per square millimeter, so to speak, the efficiency, the scalability, the power delivery capabilities, the key attributes that we know data centers, AI, and customers need, and with respect to which they are really today severely handicapped. The multi-phase approach, particularly with VPD, but even without VPD, is very, very challenged. It's been the de facto standard for obvious reasons, because it is multi-source and historically has had scalability of its own to the ecosystem of a large multiplicity of suppliers around the globe. But technically, it's very severely handicapped. It's that disability that I have, which again comes down to numbers like amps per square millimeter and other attributes, the ability to provide a VPD solution in one amp millimeter thin crowd multiplier that line up with what the AI processors require. You know, we're looking at applications with 2,000, 4,000 amp requirements. In other cases, we're looking at web-scale applications at the 50,000 amp level. You can't do that with multi-phase. You can only do it with our enabling technology. That's what we're set to enable directly with our fab, and to some degree indirectly through our licensee model.
Unidentified Analyst, Analyst
Okay. Appreciate those, I appreciate you. That's all for me.
Patrizio Vinciarelli, CEO
Thank you. And with that, we'll have to wrap it up.
Jim Schmidt, CFO
So, operator, if you could close the call. Thank you.
Operator, Operator
Sure. Thank you, everyone. That marks the end of your webinar. Thank you for joining, and have a nice day.
