Hello, everyone. Thank you for joining us today, and welcome to Magnachip's Q4 earnings call. First, I believe it's important for investors to understand how our financial results fit into the big picture as we undergo a substantial transformation in our business over the next couple of years. First, we are dramatically shifting priorities in our display business to be laser-focused primarily on China. This strategy builds upon 20 years of OLED driver success, primarily in Korea, and follows the industry's dramatic shift to China production. Second, we will be working this year and next to fill ideal fab capacity in our Gumi Fab as we transition away from supplying non-core transitional foundry services to higher-margin power products. Third, starting early this year, we began operating under a new structure that streamlines our go-to-market strategy, strengthens the potential for increased shareholder value, and also improves transparency for investors.
Let me provide more detail on each of these transitions. The first major transition involved China, which is becoming the new center of the OLED display universe. We are executing on a strategy to penetrate this vibrant market with feature-rich OLED standard products, and I'm pleased to say we've made tremendous progress so far. We've laid the groundwork for success by establishing a China-dedicated entity and by building strong working relationship with Chinese panel makers and leading smartphone OEMs. Over the past few quarters, we've doubled our resources and staff in China, amassing a team of more than 20 professionals dedicated specifically to our OLED display business. In addition, we hired senior advisors from a top 5G semiconductor company, the financial services sector, and the China supply chain to help accelerate our progress.
I now personally travel to China on nearly a weekly basis to meet our strategic customers, partners, and strategic OEMs. Our work in China is beginning to pay off. We've already secured two smartphone design wins with leading OEMs and expect more on the way. It's part of our strategy to serve the full spectrum of models, from mainstream to affordables. I'm confident that the results of our strategy will become apparent beginning later this year, with more significant revenue growth expected in 2025. The second major transition involves the idle capacity we expected in our Gumi fab, created by the wind down of our transitional foundry services business. We plan to fill the idle capacity with our existing power product portfolio, as well as a new slate of next-generation power products that we will introduce over the next several quarters.
We believe these products will be on a par with some of the best global suppliers of power products. As we've said previously, this fast transition will depress gross margins until we can adequately replace the legacy transitional foundry services business with higher-margin power products, and we intend to share updates on our perspective on this transition on a quarterly basis. To help achieve our goal during these transitions, we've now streamlined the structure of the company by creating two main business entities to better align our product strategies, and also to provide more transparency to investors through our new MSS, Mixed Signal Solutions, which includes display and Power IC products, and PAS, Power Analog Solutions, our traditional power-discrete businesses. To help investors better track our business progress, we will break out MSS and PAS revenue, as well as gross margin, beginning on the Q1 earnings call.
The reasons for deciding to separate the standard products business structurally and operate independently are mainly because display and Power IC are fabless and power-discrete is an IDM business. In addition, the separation allows the following benefits: One, increase shareholder value by maximizing the valuation of each business. The separation allows a foundation for more efficient and transparent business structure that can fuel sustainable growth through strategic financing and investment. Two, strengthen business performance management by establishing independent and responsible management systems. Three, enhance flexibility in business portfolio and increase strategic responsiveness to environment changes. We are confident that the strategies I've outlined will put us on a path to achieve a sustained recovery over the next two years. While we typically provide guidance for one quarter only, I feel it's important in the current environment to provide directional guidance for 2024.
We currently expect double-digit revenue growth in both the newly organized MSS and PAS businesses. Overall, we expect total company revenue to be flat to up slightly in 2024 over 2023, primarily due to the phase-out of the transitional foundry services. Gross margin for the consolidated company is expected to be in the range of 17%-20% for the year, severely impacted by the idle capacity when the transitional foundry service revenue winds down. While the near-term outcome is disappointing, rest assured that my team and I are committed to working every day on behalf of our shareholders to improve the results. Now that I've provided a big picture context, let's review our Q4 results. Revenue was $50.8 million, and gross margin was 22.7%, both near the low end of our guidance range.
During the quarter, our OLED business was impacted by slower design win progress than expected, due to longer OEM evaluation cycles. During Q4, we also embarked on another key OLED project aimed at diversifying our customer base to enter the smartwatch display market. Our power business results were down 20.5% sequentially, primarily due to the ongoing inventory correction in industrial end markets, particularly in China's e-bike market and the solar sector. Now, let me provide updates to each of our business under the 2023 financial reporting convention. Beginning with our display business, Q4 revenue was in line with our expectation at $5.2 million, down 30.8% year-over-year and 18.3% sequentially.
We received our first pilot production purchase order in China for our first chip from an after-service market player during the December quarter, and we are making progress on many additional fronts. Specifically, Q4 marked the beginning of initial shipments in China of our first OLED DDIC chip that we taped out in 2022. In Q4 2023, we were awarded our first design win and related PO for the after-service market. While its immediate financial contribution expected to be modest, it marks our first pilot production PO in China and is a significant step towards the acceptance of our product capabilities, as well as our team's efforts. Moving on to our current generation of OLED DDIC products. Our third OLED DDIC chips successfully completed design-in evaluation at a leading Chinese smartphone OEM, and been assigned a high volume model for launch in Q2 2024.
This resulted in a Design Win with obtaining pilot production PO as a second-source supplier. For this leading Chinese smartphone OEM, we've been qualified and added to their approved vendor list. Moreover, we've been chosen to also work with them on their fold model with our next-generation chip, which we prioritize and will sample next quarter. Additionally, our second chip is still going through our design-in evaluation phase at a global smartphone OEM. We will provide an update on this once we receive the status from the OEM evaluation. Mid last year, we announced that we began developing another OLED DDIC chip targeted for fast-growing foldable smartphone market.
Third-party research from China Securities estimates global foldable handsets are projected to grow over 50% year-over-year, the next few years, and reach over 100 million units by 2027 from just approximately 15 million units today. Finally, we're excited to announce that we partnered with a watch solution maker in China during Q4 to develop a new product targeting the OLED smartwatch display market. This is an adjacent market. We are applying our smartphone DDIC technology know-how and development expertise. The delivery of first sample is expected in mid-2024. This initiative demonstrates our strategy to expand into new high-growth markets with new product offerings that showcase our ability to innovate across segments.
With regard to our OLED automotive business, we began production shipments to our large Korean panel maker for three different car models from two top-tier European car manufacturers between May and July 2023. Modest revenue flow from those devices began in May 2023, and it is expected to continue for a few years, given longer automotive cycles. All these efforts underscore our commitment to innovation and market expansion. Moving on to our power business. Q4 revenue was $36 million, down 22.3% year-over-year, and 20.5% sequentially. Sequentially, our power business was impacted by an ongoing inventory correction in industrial end markets, particularly e-bike and solar. We also saw weakness in consumer TV and PC power.
On a positive note, we secured two new smartphone design wins for our low-voltage MOSFET family, which grew more than 20% sequentially in the fourth quarter for that product family. While the overall power business results in the fourth quarter were disappointing, we currently expect a gradual recovery in our power business in the first half of the year, with increased momentum in the second half. Our major markets, such as consumer, computing, and communication, already underwent a major inventory correction over the last year. We continued to focus on execution in Q4. We developed and launched new power products and saw strong momentum in our design win activities. In Q4, we secured a new design win and began mass production for a major U.S. automotive brand that will contribute to revenue growth in 2024.
I am extremely proud of the progress we've made in our automotive business, as revenue for the full year 2023 is up over three times compared to 2022. I look forward to building on this momentum in coming years. We also continue to innovate. In October, we announced two new 650-volt super junction MOSFET that reduced the overall footprint by nearly 60% as compared to other products from competitors. These new MOSFETs offer excellent design flexibility, efficient heat dissipation, and low resistance characteristics. As a result, they are well suited for various applications that require compact size and high efficiency, such as OLED TVs, servers, lighting products, and laptop chargers and adapters.
In summary, our power business, our product portfolio is getting stronger as we continue to focus on rolling out our next-generation power power products to maintain our momentum of design-ins and wins. These new products will provide the foundation to fill our Gumi fab, achieve better margin, and help us get back to profitability. Entire families of our next-generation products will be forthcoming in 2024. We will be releasing the next-generation 650-volt IGBT in the first half of 2024, followed by sixth-generation Super Junction MOSFETs and sixth-generation IGBTs in Q3 of this year, and eighth-generation medium-voltage MOSFETs and eighth-generation low-voltage MOSFETs in Q4 of this year. We expect these next-generation product families to match or surpass the performance of our Tier One competitors.
This will position us well to compete for high-end industrial and automotive markets, as well as serve our existing markets, such as consumer, computing, and communications, better. Additionally, we will be introducing a new line of commodity products by end of the first quarter to improve fab utilization. I'll come back to wrap up the call after Shinyoung gives you more details of our financial performance in the fourth quarter and provide Q1 and full year 2024 guidance. Shinyoung?
Thank you, YJ, and welcome to everyone on the call. Let's start with key financial metrics for Q4. Total revenue in Q4 was $60.8 million, down 17% sequentially and down 16.7% year over year.... Revenue from the standard products business was $41.2 million, and revenue from transitional foundry services was $9.6 million. Within standard products, display business revenue was $5.2 million, and power business revenue was $36 million. Gross margin in Q4 was 22.7%, down from 23.6% in Q3, mainly driven by lower fab utilization. Compared to the same period last year, gross margin decreased 370 basis points from 26.4%, primarily as a result of unfavorable product mix, lower fab utilization, and higher fab costs.
Going forward, please keep in mind that there likely will be more volatility in our gross margin due to the relative sizes of the newly organized businesses on a standalone basis. In addition, among other things, product mix, fab utilization, and input manufacturing costs will impact our quarterly gross margin by business. As a reminder, our transitional foundry services contract with SKH Foundry expired at the end of August 2023, and we are planning to wind down these foundry services starting in Q1 2024, and the revenue is expected to be approximately $2 million-$3 million per quarter in the first half of 2024. Transitional foundry services accounts for approximately 30% of our Gumi capacity when fully utilized with foundry products. This anticipated decline is significantly impacting our factory utilization rate in Gumi, which is negatively impacting our product gross margin for the power business.
Turning now to operating expenses. Q4 combined R&D and SG&A was $27.5 million. This compares to R&D and SG&A of $23.7 million in Q3 2023, and $26.2 million in Q4 last year. R&D in Q4 was $15.4 million, as compared to $11.6 million in Q3 and $13.7 million in Q4 last year, due to higher mask set cost. Stock compensation charges, including operating expenses, were $1.7 million in Q4, compared to $2.1 million in Q3 and $1.5 million in Q4 last year. Q4 operating loss was $15.9 million. This compares to an operating loss of $9.2 million in Q3 and operating loss of $10.1 million in Q4 2022.
On a non-GAAP basis, Q4 adjusted operating loss was $14.1 million, compared to adjusted operating loss of $7.1 million in Q3 and $8.6 million in Q4 last year. Net loss in Q4 was $6 million, as compared with a net loss of $1.2 million in Q3 and a net income of $3 million in Q4 last year. Q4 adjusted EBITDA was -$10 million. This compares to a -$2.7 million in Q3 and -$4.8 million in Q4 last year. Our GAAP diluted loss per share in Q4 was $0.16, as compared with diluted loss per share of $0.13 in Q3 and diluted earnings per share of $0.07 in Q4 last year. Our non-GAAP diluted loss per share in Q4 was $0.21.
This compares with diluted loss per share of $0.04 in Q3 and $0.36, $0.36 in Q4 last year. Our weighted average diluted shares outstanding for the quarter were 38.8 million shares. In Q4, under our new stock buyback program authorization of $50 million, we repurchased approximately 1.1 million shares or $8.2 million. We had about $36.4 million remaining out of the new $50 million program at the end of December 31, 2023. Moving to the balance sheet. We ended the quarter with no debt and cash of $158.1 million, down from $166.6 million at the end of Q3 2023. The primary cash outflow during the quarter was approximately $8.2 million of stock buybacks.
Net accounts receivable at the end of the quarter totaled $32.6 million, which represents a decrease of 20.6% from Q3 2023. Our days outstanding for Q4 was 59 days and compares to 62 days in Q3. Our average days in inventory for Q4 was 77 days and compares to 61 days in Q3. The absolute dollar value of our inventory was up slightly quarter-over-quarter, while lower cost of sales primarily drove the calculation for days of inventory higher. Specifically, inventories net at the end of the quarter totaled $32.7 million. This compares to $30.8 million in Q3 2023. Lastly, Q4 CapEx was $4.7 million, and for the full year 2023, we spent $7 million in line with our previous estimate that we affirmed last quarter.
Now moving to our first quarter and full year 2024 guidance. Beginning in Q1, we'll begin reporting results under the newly organized businesses, MSS and PAS. While actual results may vary, for Q1 2024, Magnachip currently expects consolidated revenue to be in the range of $46 million-$51 million, including approximately $3 million of transitional foundry services. MSS revenue to be in the range of $8 million-$10 million. This compares with MSS equivalent revenue of $8.6 million in Q4 2023. PAS revenue to be in the range of $35 million-$38 million. This compares with PAS equivalent revenue of $32.6 million in Q4 2023. Consolidated gross profit margin to be in the range of 17%-20%.
MSS gross profit margin to be in the range of 40%-43%, which includes the positive impact of expected one-time non-recurring engineering revenue. This compares with MSS equivalent gross profit margin of 41.3% in Q4 2023, which also included one-time non-recurring engineering revenue. PAS gross profit margin to be in the range of 15%-18%, due primarily to the expected decline in transitional foundry services revenue. This compares with PAS equivalent gross profit margin of 18% in Q4 2023. For the full year 2024, we currently expect MSS revenue to grow double digits year over year, as compared with MSS equivalent revenue of $44.4 million in 2023. PAS revenue to grow double digits year over year, as compared with PAS equivalent revenue of $151.3 million in 2023.
Consolidated revenue flat to up slightly year-over-year, as recovery in MSS PAS is offset by the phaseout of transitional foundry services. Consolidated gross profit margin between 17%-20%, due to idle capacity expected from the phaseout of transitional foundry services. This compares with the consolidated gross profit margin of 22.4% in 2023. Thank you, and now I'll turn the call back over to YJ for his final remarks. YJ?
I want to emphasize points I made earlier, because they are important for investors to understand where we are and where we are headed. One, our display business is building upon our past success in Korea to focus more squarely on China. As a sign of the importance of the China market, we have formed a dedicated China operating entity, enabling us to forge strategic partnerships with key players in the smartphone, TV, automotive, and ecosystems. This move strengthens our market presence and fosters valuable relationship within the industry. As we benefit from these strategic initiatives in our China operations, we are optimistic about the trajectory ahead for our display business. Two, we are dealing ahead on, with an expected drop in fab capacity in our Gumi Fab as a result of the expected drop-off in transitional foundry services, and we'll provide regular updates on our plan.
3, we've separated the structure of the company into two entities to increase shareholder value by maximizing the valuation of each segment, strengthening business performance management, and enhancing flexibility to respond to changes in the business environment. The move also will dramatically increase our transparency to the investor community. Thank you to our shareholders for your patience. We appreciate your support as we work to achieve our goals. Now, I will turn the call back to Steven. Steven?
Great. Thank you. That concludes the prepared remarks section of our call today. Operator or Jonathan, would you now open up the call for questions?
Certainly. One moment for our first question. Our first question comes from the line of Suji Desilva from Roth Capital Partners. Your question please.
Hi, YJ. Hi, Shinyoung. So, YJ, in the display market in China, you say you have two smartphone OEM wins. Are those wins secured directly by you or by the display partner you have? Just want to understand how those OEM wins are gonna be secured going forward.
Yes. In China, we sell to the panel customer and the smartphone OEMs. They also dictate which DDIC they like to use as well. So, as I said, we doubled our resources in the last few quarters. We have more than 20 professionals, and also we have added three more direct OEM sales to smartphone and to the OEMs. And I've also hired three advisors to help out from the top 5G semiconductor companies and supply chain, so forth. So, we are using both sell to the panel as well as the smartphone OEMs, and that's how we're gonna accelerate and win more sockets.
Okay. Also in the display market, can you tell me how many products you have now targeting the China market in total? And what is the after-service market? Is that a special market that needs special products?
Yeah. So let me talk about the after-service market. So after-service market is like either refurbished of phone or when your screen goes off, then you have to replace. According to market research, that market now is anywhere between 10%-20% of smartphone market, and as you saw, there's an increase in used smartphones. So I think that's what we are seeing. That's the first question answer. And then, the what was the-
How many products do you have?
The number of products.
The number of products we now have in China, we have three, and I said we're gonna have another chip coming out next quarter, and then we are working on the foldable and the mainstream product. That'd be all out this year.
Okay, great. And then last question, as you convert the foundry services at Gumi to power, what-- how should we size the revenue opportunity once that's fully converted incrementally for your power business? The opportunity at least capacity-wise.
Yeah. So I think there are two vectors there. One is, how are we gonna fill the fab? The how we're gonna fill the fab is, during the transition. First of all, you know, we're gonna have a bunch of new products. As I said today, we have a slew of new generation coming out all this year. So we have a 650-volt IGBT in first half, followed by sixth generation super junction and IGBT in Q3, and eighth generation MV and low voltage in fourth quarter, and then another commodity product line to fill the factory in fourth quarter. So that is a product strategy to fill, and then in the second half, we will be converting the fab to our products and fill it up.
So, once all that is achieved, we expect revenue to go beyond what we did in the past. But, you know, it will take a little time.
Understood. Maybe one last question for Shinyoung, and I'll go, I'll hop back in the queue. Shinyoung, for the NRE, for the gross margin for MSS, how much of that was NRE benefit? If you could roughly size that, that would be helpful.
It's probably the normalized basis. It's probably 30%+.
30% of the margin?
So, no, no, no. So 41% is just because of that, the one-time thing. So without that NRE, kind of normalized-
Okay.
-display at this stage is 30+. So 30%-
Got it.
Like a couple % more than that. Yeah.
Got it. That's helpful. Okay, thanks, guys.
Thank you. One moment for our next question. Our next question comes from the line of Quinn Bolton from Needham. Your question, please.
Hey, guys. Nick going on for Quinn. Just a quick one. Will you provide a historical breakout of MSS and PAS?
We will. We will, yes.
Okay, great,[crosstalk]
Technically, like, when we report the Q1 quarterly, you're gonna see the competitive historical period recross-
Right.
on the same basis.
Right. So we'd at least see the first quarter, but hopefully we could get some second and third quarter numbers. Great. So for gross margins, you mentioned, you know, we should expect volatility. You're winding down the transitional foundry services, I think, by the end of the second quarter. So how long will that Gumi Fab be, you know, at least 30% underutilized? I guess I'd expect margins to maybe bottom in 2Q and remain low, maybe flat, 3Q into 4Q, perhaps. I mean, after last quarter, I think we are expecting margins to bottom in the 3Q, 4Q timeframe. So are you kind of pulling that in with maybe an accelerated foundry wind down? I guess, what's the best way to think about, you know, the margin pattern?
I mean, we are gonna still have some foundry services revenue, like $2-$3 million per quarter in Q1 and Q2. So technically, we can't really do anything about the 30% capacity in our Gumi Fab, and we are gonna wind down after the Q2. So I mean, we're gonna see some, the idle capacity in the second half as well, until we fully convert that fab capacity to power, the PAS, the product. So you're gonna see that the margin kind of depression of throughout the year.
But, I think in the second half, the difference is that we are rolling out by the time all the new generation, which has higher margin and lower cost. So, that will be the lever that we'll try to maximize the margins.
Okay. I think I understand. I mean, when you kind of, you know, finish the idling process, maybe margins bottom in the third quarter and then stay flat until, you know, fill up the fab. That's what it sounds like. So in the power business, you talked about an auto win that will contribute in 2024. So a couple questions there. Just how do we think about sizing that win? Maybe when will it begin to ramp? What was the main, you know, technical driver of that design win? And then how does that ramp play out with your, you know, Gumi fab utilization? Sounds like that would kind of help in the 3Q, 4Q timeframe.
So the automotive, as you know, we didn't have any automotive business about 2 calendar years ago, and the 2022 was first year, maybe it was 1% or less than 1% revenue. Last year, we had about 5% of revenue. And then this year will still grow a high double digits. So that's about the size of the automotive business. But we now have more than two dozen design-ins and wins in automotive, and we are still having the momentum.
Thank you.
Thank you. One moment for our next question. Our next question comes from the line of Martin Yang from Oppenheimer. Your question, please?
Hi, thank you for taking my question. My first question is about your customer engagement activities in China. Can you talk about, you know, how many customers are you actively engaged with? And are the new wearables and aftermarket wins with the same customer?
Yes, a very good question. So, we are discussing with direct panel customer, like the, the panel guys. So we have a two panel guys we're doing business now. And, we are actively engaged with, top, five out of six, smartphone OEMs directly, and so that's what we are doing.
Got it. Thank you. A question on margins for discrete, power discrete products. And, you know, how does the current margin compares to, historical levels, especially historical peaks? And what needs to happen, before we see that discrete product, power product margin recover back to where it was?
I mean, as YJ mentioned, that like once we convert that, the 30% of the idle capacity for the power discrete, but we are gonna roll out with a new generation power product, series of them, which we're gonna have a higher margin. So once we kind of replace the foundry product, like, you've seen the negative margin. The thing is, ASP was fixed for those products, but the cost was high. So the power now have to absorb those fixed costs from those foundry, but if we fill that capacity with a higher margin product based on the new generation product series, and we have a potential to go back to our historical kind of high level.
Got it. And, so what else needs to happen fundamentally for you to fully fill that capacity?
Yeah. So I think, that's a very, we've been saying that today, that is our top priority, and it's about, having the right product portfolio. And so we already had a 650 volt super junction in the October release. That's like 60% better than before. We are introducing the new 650 volt IGBT in first half, followed by sixth generation super junction and sixth generation IGBT in the third quarter, and eighth generation medium voltage and low voltage MOSFET in fourth quarter. And additionally, we'll have a new line of commodity product on the fourth quarter. So those will drive to fill the fab with a better margin and better performance.
Thank you, YJ. That's it for me.
Thank you. This does conclude the question and answer session of today's program. I'd like to hand the program back to Steven Pelayo for any further remarks.
Okay, great. Thank you. This concludes our Q4 earnings conference call. Please look for details of our future events on Magnachip's investor relations website. Thank you, and take care.
