Now I'd like to turn the call over to Everspin's President and Chief Executive Officer, Sanjeev Aggarwal.
Sanjeev, please go ahead.
Thank you, operator. Thanks everyone for joining us on the call today. Everspin delivered quarterly revenue of $15.7 million above the high end of guidance, leading to an all-time record full year revenue of $60 million for 2022. We were GAAP net income positive for the seventh quarter in a row, which continues to be a focus for the company. A few records we reached in Q4 for the full year 2022 include record annual total revenue, record annual product revenue, record annual net income, record annual cash flow from operations, record annual EBITDA, record annual design wins again in 2022 after setting a record in 2021. Next, a few highlights for Q4 2022 and the full year 2022 include revenue for Q4 was $15.7 million, up 3% quarter-over-quarter.
Full year revenue was $60 million, up 9% year-over-year. Product sales were $14.6 million, consistent quarter-over-quarter. Product sales for the full year were $55 million, up 25% year-over-year. Cash flow from operations was $5.2 million in Q4, totaling $9.5 million for the full year. GAAP gross margin was 56.6% for the year, and GAAP net income was $6.1 million for the year. Our business outlook. Our product backlog for balance of 2023 as of December 31st, 2022, continues to be high. Although we are experiencing some headwinds from the semiconductor downturn. We continue to alleviate some of our foundry supply chain constraints, which is helping address our unfulfilled Toggle demand.
Turning to technology, Everspin remains confident in its future opportunities and continues to invest in our leadership in STT-MRAM technology. We have tuned our STT-MRAM technology to deliver high performance persistent products for multiple non-volatile memory markets, including DRAM, SRAM and NOR flash. Our STT-MRAM products, targeting the replacement of battery-backed DRAM, started production in 2017 and are currently shipping in 256 Mb and 1 Gb densities with DDR3 and DDR4 derivative interfaces. These products are delivering significant value to SSD, persistent memory cards, fabric accelerator, and other applications in the data center market. In 2022, we introduced a xSPI family of STT-MRAM products that was developed by tuning our STT-MRAM technology for DRAM to scale our Toggle MRAM offerings to higher densities on advanced CMOS nodes.
These products are available on 28 nanometer CMOS node in densities from 8 Mb - 128 Mb, with standardized SPI, Quad SPI, and Octal SPI interfaces. These products are enabling our customers to simplify their system architecture and easily replace legacy memory components like SRAM and ferroelectric memories or FRAM. Based on the strong interest and feedback from our customers in this new xSPI family of STT-MRAM devices, we designed and taped out an optimized solution on 28 nanometer CMOS for lower densities from 4 Mb - 6 Mb in Q4 of 2022. This allows us to better compete with alternate memory solutions in this density range. This family of products are ideal for use in electronic systems like industrial IoT, network, enterprise infrastructure, process automation and control, aeronautics, medical, and gaming.
Due to the limitations of NOR scaling past 45 nanometer, we believe there is a potential for STT-MRAM for discrete NOR flash replacement similar to the embedded market. We tuned our STT-MRAM technology and introduced the first STT-MRAM product addressing this segment of the market in 2022 as well, and are currently shipping in 16 Mb - 128 Mb densities. Everspin, with its experience in higher density greater than 256 Mb STT-MRAM products, is uniquely positioned to design and manufacture monolithic high-density discrete parts for NOR replacement. The first such product is in the design phase, and when available, would be ideal for replacing NOR, for example, in FPGA systems to store configuration memory and simultaneously enabling 100x faster over-the-air updates. Switching to a different technology that could benefit greatly from STT-MRAM.
In Q4 2022, we announced a collaborative engagement to develop strategic Radiation-Hardened FPGA technology. As part of the collaboration, Everspin will provide a STT-MRAM solution that acts as the configuration memory in the FPGA, thus eliminating the off or on-chip NOR die and the SRAM cells that execute the lookup tables. The STT-MRAM-based configuration memory can be programmed multiple times with fast OTA updates or can be hard-coded depending on the application. STT-MRAM can be scaled to advanced nodes and is already available on 22 nanometer and below, monolithic embedded solutions will be possible. We believe this solution from Everspin will play an important role in next-generation FPGAs. I will now turn it over to our CFO, Anuj Aggarwal, who will take you through our fourth quarter financials and first quarter 2023 guidance. Anuj.
Thank you, Sanjeev, and good afternoon, everyone. As part of the fourth quarter of 2022 financial results, Everspin Technologies is pleased to announce its seventh consecutive quarter of positive, meaningful net income. In addition, we generated positive cash flows from operations, resulted in a healthy cash balance of $26.8 million. We delivered solid quarterly results above the high end of guidance with revenue of $15.7 million compared to $15.2 million last quarter and $18.2 million in the fourth quarter of 2021. We also had positive net income of $0.6 million and positive cash flow from operations of $5.2 million for the fourth quarter of 2022.
MRAM product sales in the fourth quarter, which included both Toggle and STT-MRAM revenue, was $14.6 million, consistent with the prior quarter at an increase from $12.6 million in Q4 of 2021. Licensing, royalties, patents, and other revenue in the fourth quarter was $1.1 million, compared to $0.7 million in the previous quarter and $5.6 million in Q4 of 2021. Shipments to suppliers for our largest end customer, who we serve with our high-density STT product for data center applications, represented 5% of revenue in the quarter versus 19% of revenue in Q3 and 16% in Q4 of 2021. Turning to gross margin, GAAP gross margin for the fourth quarter of 2022 was 51.4% versus 58.8% in the prior quarter and 62.8% in Q4 of 2021.
GAAP operating expenses for the fourth quarter of 2022 were $7.5 million versus $7.1 million in the prior quarter and $7.7 million in the fourth quarter of 2021. The higher operating expenses in the quarter sequentially was primarily driven by increased costs to support the new STT industrial product that went into low volume production in Q4. We are pleased to report fourth quarter positive net income of $0.6 million or $0.03 per basic share based on 20.1 million basic weighted- average shares outstanding. This compares to a GAAP net income of $1.9 million or $0.09 per basic share in the third quarter of 2022, and net income of $3.7 million or $0.19 per basic share in the fourth quarter of 2021.
Basic EPS of $0.03 was better than the midpoint of our guidance range, reflecting our strategic operational discipline and ability to drive profitability in the face of tightening supplies and macroeconomic uncertainties. Adjusted EBITDA continues to remain positive. For Q4 2022, Adjusted EBITDA was $2.1 million compared to $3.4 million in the prior quarter and $4.8 million in Q4 2022. Adjusted EBITDA for the full year of 2022 is at a record high of $11.8 million. Cash and cash equivalents increased to $26.8 million at the end of the fourth quarter compared to $23.4 million at the end of the prior quarter and $21.4 million in Q4 2021. Cash flow from operations was $5.2 million for the current quarter, increasing the year's cash flow from operations to $9.5 million.
Turning to our first quarter of 2023 guidance, Everspin is confident in its opportunities and ability to navigate the semiconductor macroeconomic challenges. Demand for our Toggle products remains strong. Everspin expects total revenue in a range of $14.1 million-$14.8 million, Everspin expects GAAP net income per basic share to be breakeven to $0.05, primarily influenced by expenses related to our next generation 20 nanometer STT-MRAM product development and price increases from our suppliers. I now turn it back over to Sanjeev for some brief additional commentary before we open it up for questions.
Thanks, Anuj. In summary, Everspin reported the best financial year in the company's history with strong fourth quarter results. We continue to build towards the future of profitable, sustainable growth thanks to the hard work and dedication of the Everspin employees. We are confident in our future opportunities and are excited to see the interest from our customers in our STT-MRAM products. Thank you for joining us today. Operator, you may now open the line for questions.
Thank you. As a reminder, to ask a question, you'll need to press star one one on your telephone. To withdraw your question, please press star one one again. Please wait for your name to be announced. Please stand by while we compile the Q&A roster. One moment for our first question. Our first question comes from the line of Richard Shannon with Craig-Hallum. Your line is open.
Well, hi, guys. Thanks for taking my questions here. I think the first one I'd like to ask guys is, in the broader dynamics in the semiconductor space here, we've seen, some inventory builds, and a lot of companies have seen some pretty significant burns here of late. You're not seeing it, at least so far, but I know you've got some capacity constraints you're still working through. I guess I'd love to get your best take on the degree to which, or I guess maybe think about first about when you expect these constraints to be overcome. Do you worry, and have you talked to your customers about backlogs and bookings, that may fall off as they're, become more comfortable with the inventory, that they can get from you?
Hi, Richard. This is Anuj. Yeah, great question. Let me, let me try to take it in a couple of pieces. As we look at the backlog, right, it continues to be healthy. In 2023, we've got solid demand. We have demand going out to 2024. From that perspective, you know, things are looking good. Really high visibility into 2024 as well, right? There have been, I mean, some cancellations, some pushouts, so there has been some macroeconomic effects that we've seen. But I think overall, what we've been able to do is because of the high amount of backlog, we've been able to pull in demand from future quarters and really work through that. Now from a customer standpoint, I think you were asking about that as well.
We've been working very closely with our customers to understand not only what their current demands are in the current quarter and future quarters, but then also working with them to understand when there are opportunities and capacity frees up, are they interested in getting the product sooner? We're working very closely with them to pull in demand where it makes sense as capacity frees up.
Okay. Okay, fair enough. I might come back to this topic here in a second. Maybe asking a more tactical question here in the first quarter. I know you don't, you know, really delineate with any specifics about how you're building up to the quarter here. I would assume that there's probably a big chunk of it, of licensing revenue falling off quarter-on-quarter with some more modest drop off in Toggle to get to the revenues, kinda midpoint of the revenues. Is that a fair way to think about this, or is Toggle and product revenues gonna be down more than licensing?
Yeah. The, the way I think about it is the way we built the $14 million - $14.8 million guidance in revenue, you know, we continue to feel that Toggle is strong. The backlog is very promising in 2023 going out to 2024, I think that piece is strong. The part that's a little bit of a challenge that I think we've shared before is we've seen STT demand, you know, with our key key customer, that's kind of tapered off a little bit. But it's strong in that perspective from a total product revenue standpoint. From licensing, that continues to go up and down, right? As we see opportunities for patent deals and things like that, none of that's incorporated into the guidance.
Okay. That is helpful. Maybe another line here on the income statement to talk about here, both for the fourth quarter and going forward here. Gross margins, and I like to focus on the product gross margins, if I did my math right, did roughly 49% in the fourth quarter. Well, first three quarters of the year, you're between 54% and 58%. I think you had a more optimal mix in the past quarters, but also some strong yields. How do you explain the drop-offs here into the fourth quarter? How much of that was yields, product mix, and other dynamics?
Yeah. I'll try to be a little careful here 'cause I know we don't provide too much guidance on gross margin, right? I'll say that, you know, we've always communicated that our internal model is between the low to mid fifties. I think as you're seeing the yield stabilizing and the product mix stabilizing, you're getting back to a more normal expected, range for the gross margin, and that's evident in the guidance that we're providing. In Q4, we did see a little bit higher supplier costs and things like that, but overall, we feel like it's more in line with the internal model that we've shared in the past.
Okay, fair enough. let me jump over to Sanjeev. talking about the new xSPI product here. I just wanna kind of ask a big picture, top-down question here on how you see this product ramping out this year, and if you could give us some maybe bottoms-up thoughts here on, you know, attached to FPGAs, MCUs, and others, and which densities you're seeing to pick up. And ultimately, how can we think about the revenue contribution from that product line this year?
Hi, Richard. Thank you for your question. I think it's an important question to understand our revenue profile going forward. I think the way to think about it is that, you know, most of our adoption is in the industrial markets, so it is a long cycle time for qualification. I don't think you're going to see significant revenue from the 64 Mb or the 16 Mb in 2023. Having said that, we have seen strong traction with our customers in Q4 and in Q3 last year, which actually prompted us to tape out a more optimized density and die size at 16 Mb. What that did for us is it actually opened up the customers that were using alternate memories like SRAM, nvSRAM, or ferroelectric memories, FRAM.
I think about us taking over some of the market with the lower density parts from nvSRAM and FRAM. The high density, the 64 Mb and the 32 Mb, for example, they're going to basically attach to industrial IoT applications, aerospace and defense, process automation, you know, the standard application that you've seen Toggle MRAM get into over the last decade or so.
Okay. That's fair enough. One last question for me. I'll jump on the line here on OpEx here. You've had, you talked about the last couple of quarters about OpEx coming up here as you're investing more in this new STT-MRAM line. How much longer are we gonna see kind of, you know, elevated levels of investment, mostly from the R&D line? Do we see it getting back down to, you know, levels seen earlier last year? How do we think about that long term?
Yeah, no, great question. You know, so we don't normally provide guidance on the OpEx, but what I can share is, you know, what we expect it to be a little bit higher in Q1, right. As we're getting ready and taping out the lower density product and getting everything ready. I expect it to kind of level off and slightly decrease as the year progresses, so that. If that helps.
Yep, that does help me. I've asked enough questions, so I think I'll jump out of line, but thanks for all the answers, guys. Appreciate it.
Thank you, Richard.
Thanks, Richard.
Thank you. One moment for our next question. Our next question comes from the line of Rajvindra Gill with Needham & Company. Your line is now open.
Thank you, and congrats on solid results in light of a very kind of tumultuous environment. Just, Sanjeev, a question on the xSPI family and the ability to replace discrete NOR, you know, for certain industrial applications, IoT applications. Now that you have kind of a higher density range with respect to the xSPI family, what has been the feedback from the customers in terms of the cost benefit of replacing discrete NOR with STT-MRAM? Is it on the cost side? Is it on the instant-on access side? What's been kind of the feedback?
That's been the thesis for a while, is that MRAM combined the benefits of volatile and non-volatile, but the issue has been kind of around density. Just curious of what you're hearing from customers.
Yeah. Good afternoon, Rajvi . Good question. basically, if you look at, the way the NOR is used in current FPGAs, right? it's basically it takes forever to write, but the read speeds are pretty fast. That's where STT-MRAM is actually being appreciated by some of our customers. it's basically, the fast, the writes are much faster, so the faster over-the-air updates. The read speeds are similar. The other thing that it does is it actually allows you to store, multiple bit streams in the memory. In that way, you can actually have two streams or three streams stored, depending on the number of LUTs and the number of, and the density of the STT-MRAM that you're using.
Where people value the faster write speeds, the longer endurance and the lower power to actually write those configuration streams, I think that's where we're getting good traction from our customers. But where we are in a cost competitive environment, you know, NOR is obviously much cheaper than STT-MRAM, and that's where we get seeing less of attraction. Again, just like our previous applications, customers that value our performance are adopting our parts.
More thinking about, you know, calendar 2024. First, the opportunity with the Department of Defense for the RadHard product, where, you know, you sign the extension of the RadHard deal, which will has built in some technical milestones before the licensing revenue will come and then the broader push there. Can we talk about kind of that opportunity on the RadHard in calendar 2024? You also talked about, you know, the industrial, since the design cycles are taking long, you know, it take a fair amount of time that you'll won't see it in 2023, but you'll see it in 2024. How do we think about that impact potentially on 2024 with those two budding opportunities?
For this year in 2023, what do you think will be the kind of the main growth driver for this year?
Right. If I deviate from the question, please stop me, okay? As I answer. I'll start with the last question. For 2023, what are the growth paths? I think there you're seeing our 16 Mb and 64 Mb STT-MRAM part. I think those getting traction and starting to see initial revenue from there. It's not gonna be huge numbers, but, you know, it's gonna be decent numbers that we'll actually talk about by the end of the year. The other thing to look at is these parts, again, the 16 Mb and 64 Mb in 2024, I think will drive significant revenue growth as they get adopted and qualified in the various systems over there.
Now, switching to the RadHard product that we're talking about, I just want to comment a little bit over here. When you're looking at our 16 Mb and 64 Mb STT-MRAM for NOR replacement, that is different than the deal that we have signed to develop this strategic RadHard FPGA technology. There, you're actually replacing the NOR as well as the SRAM cells that execute the lookup tables. That is a totally different solution that we have developed based on STT-MRAM. I think for that, you will see, you know, there are some milestones to be achieved, but then you're gonna see royalty, sorry, not royalty, licensing revenue and NRE revenue from that project through 2023.
Then I think in 2024 would be the point where you can actually take this technology that we developed for this Radiation-Hard project and then try and deploy it on advanced nodes in the commercial market. I think that work needs to be done in 2023 so that we are actually ready for potential new revenue streams in 2024. Did I answer all your questions, Rajvi? I'm not sure.
No, it did. Thank you. I just wanna make sure the end product would be reconfigurable and would be an instant-on FPGA. Is that the ultimate kind of goal?
That is correct. That is correct.
Got it. Okay. Very good. I guess last question for me is, if I'm looking at kind of historically the product growth for the company, it has been, you know, quite impressive. It's if I have the math right, it's kind of grown from, you know, $40 odd million in 2020 to, you know, about $55 million in 2022. That's a little less than 40% growth. While the licensing has been lumpy as expected. That kind of product growth that you've been seeing the last couple years, maybe you could just summarize, just for everybody's purposes, you know, what's been driving that growth.
When we're thinking about longer term in terms of the product growth, acceleration, it seems like that, you know, the revenue could kinda inflect, you know, potentially higher in 2024 with some of these new initiatives with the xSPI family. Just kinda maybe if you could summarize, you know, how do we get here and kinda where are we going with the on the product side? Thanks.
Hi, Rajvi, this is Anuj. Just to kinda reiterate, right? The product revenue at the end of 2021 was about $44 million, and it grew to about $55 million in 2022 for the full year. A lot of that has been around the refocus for Toggle, right? We've had a lot of record design win years, last couple of years. This year as well was a record design win for us, where we had 210 design wins. Before that, a couple of years of 180 or so design wins. I think that reinvigoration and that importance of going back to the customers and really, you know, looking at the cash cow business for us, right?
Making sure we could get those design wins, because as you know, in industrial, for example, the customer stays for 10, 20 years, and that's critical for us in order to really lock in revenue for long periods of time. As we've seen, our data center customer, their revenue has maybe gone up and down and been a little bit challenging over the last few quarters. We've really been able to make up with it from all the hard work on the Toggle side over the last few years with the design wins. That continues to be our focus as we look into this year. I think that's also, you know, what you see in the backlog as well.
To add to that, Rajvi, your question on how do we see that in 2023 - 2024, right? What we have done is we have taken our STT-MRAM technology, and we've actually tuned it so that it actually extends our Toggle MRAM roadmap. Our Toggle roadmap basically ended at 16 Mb or 32 Mb parallel, and our serial was only at 1 Mb and 4 Mb and with a single SPI. By tuning this technology and making it similar to Toggle MRAM, we've now been able to actually extend that density all the way from 4 Mb to a 128 Mb. I think that opens up markets for us, and I think that's what's gonna lead to the growth in 2023 and 2024.
Thank you. One moment for our next question. Our next question comes from John Fichthorn with Dialectic Capital. Your line is open.
Thanks for taking my question. Nice year in a tricky environment. You've answered a lot of my questions, but I'm just hoping you could give a little more granular cover on this, the color and the shape of this year, and next or however you're comfortable talking about the growth path. You know, it looks like your customer concentration has dropped a lot, which is really encouraging and makes me think you've got a lot more customers and a lot more diversification in your revenue stream at this point, which seems like it should be more stable. You should have more visibility. You've got a lot of industrial design, which should give you more visibility. You've got decent backlog. You had great design wins.
All of these things make me think I'm looking at a business that has a pretty solid base here from which it can grow. I'd just like kinda some thoughts on that. Also, what does this year look like? Is it seasonal? Is it macro? Is it a pretty linear growth? Help us understand what kind of dynamics are gonna push and pull the growth path from here, assuming it is a growth path. Help me think about the backlog, the pipeline, the visibility, and that kind of diversified customer base you've got here, if I, if I am kind of thinking about it the right way. Thanks.
Yeah. Hi, John, this is Anuj. Let me try to tackle it. If I miss something, let me know. Just in terms of the full year, right? We typically only provide guidance for Q1. What I can say is, directionally, you know, without providing guidance, you know, we believe that there's, you know, potential for a recovery in the second half as we kinda look at things. From a backlog standpoint, you know, it continues to remain strong. We have a lot of good visibility into 2024. Like I was mentioning before, there is some uncertainty that we've seen because of the macroeconomic challenges within the semi industry, right? We have seen some pushouts and cancellations, but that's really been limited, right?
As we look at the full backlog picture, we've been able to pull in a lot of demand from the big backlogs that we have, right? From that standpoint, things have been going well. In terms of your comments about customer concentration, yeah, you're absolutely right. As we've diversified into RadHard businesses, as we've grown the Toggle business and gotten a lot more design wins and now introducing the new 64 Mb product as well, we're starting to see the customer base really increase. We went from 1,200 customers to about 1,300 customers in 2022. That customer base continues to increase. As we get design wins, we only expect that to continue to improve, right?
From a concentration perspective, you'll see that we've reduced the concentration on our big data center customer quite a bit, and that's helped us to achieve some of the numbers that we've shared last few quarters.
Thanks, Anuj.
Did I get all that or did I miss a bit of it?
Yeah. No, that's great.
Thank you. At this time, I'd like to turn the conference back over to Mr. Aggarwal for closing comments.
Okay. With that said, we'll conclude today's call. Thank you all for joining us, and we look forward to reporting our progress and results on next quarter's call. Operator, you may now disconnect the call.
