Thank you, Leanne. Welcome, everyone. And thank you for joining us today. We ended the year achieving the highest quarterly revenue in the company's history, excluding the revenue contribution from our acquisition of Lite-On Semiconductor that closed on November 30. Total organic revenue grew 7.8% sequentially and 10.7% year-over-year, demonstrating the continued success of our product, content, and customer expansion initiatives. Revenue from our Pericom products and automotive market also reached record levels, with automotive revenue growing 24% sequentially and 40% year-over-year, both of which contributed to our solid market share gains in the quarter. All of these accomplishments are notable, especially considering the ongoing global pandemic. Following the successful completion of the LSC acquisition, the integration process has been advancing smoothly. On December 1, we initially announced the new operation structure for the combined companies and have named Gary Yu, Senior Vice President, who is in charge of all the business groups and has also been tasked with all integration activities. We have been actively working to qualify Diodes' products in the LSC factory and expect to begin production in the middle of this year, with expectations to exit 2021 with significant momentum in this area. Regarding product, customer, and end market synergies, those are multiyear efforts that speed up the product development process by working closely with our customer and serving them with our combined product portfolio. As mentioned in our earlier release today, the LSC business was immediately accretive to our results, adding $0.02 per share on a non-GAAP basis in the fourth quarter. As I just mentioned, we believe LSC also offers future opportunities for synergistic growth and expansion across our end market, product offering, customers, and the manufacturing footprint. In addition to growth synergies, the repurchase of 14.7% of Diodes shares that were previously owned by LSC will drive additional earning power when combined with Diodes' solid operating average. As we look to the first quarter, we expect to further extend this strong momentum and once again set a new revenue and gross profit record, with sequential growth projected both organically and on a consolidated basis in what has previously been a seasonally down quarter for our business. This anticipated growth is being driven by record POS revenue in the fourth quarter. We look forward to reporting our ongoing progress and remaining focused on integrating the LSC business while capitalizing on long-term opportunities for continued growth and earnings expansion. With that, let me now turn the call over to Brett to discuss our fourth quarter financial results and our first quarter 2021 guidance in more detail.

Thanks, Dr. Lu, and good afternoon, everyone. As part of my financial review today, I will focus my comments on the sequential change for each of the line items and would refer you to our press release for a more detailed review of our results as well as the year-over-year comparisons. Revenue for the fourth quarter of 2020 was a record $350.4 million, which included $16.9 million of one month of revenue from LSC, an increase of 13.2% on a consolidated basis and 7.8% on an organic basis from the $309.5 million in the third quarter of 2020. Gross profit for the fourth quarter was also a record at $122.7 million and included $2.5 million from LSC, or 35.0% of revenue on a consolidated basis and 36.0% of revenue for Diodes only. This compares to $111.1 million or 35.9% of revenue in the third quarter of 2020. GAAP operating expenses for the fourth quarter of 2020 were $82.9 million or 23.7% of revenue; on a non-GAAP basis, they were $75 million or 21.4% of revenue, which excludes $4 million of amortization of acquisition-related intangible asset expenses, $2.5 million in restructuring costs, and $1.5 million of other acquisition-related costs. This compares to non-GAAP operating expenses in the prior quarter of $73.2 million or 23.7% of revenue. Total other expense amounted to approximately $3.7 million for the quarter, including $4 million in interest expense, $3.7 million in foreign currency loss, partially offset by $3.5 million of other income and $487,000 of interest income. Income before taxes and non-controlling interest in the fourth quarter of 2020 was $36.1 million compared to $33.3 million in the previous quarter. Turning to income taxes, our effective income tax rate for the fourth quarter was approximately 16.7%. GAAP net income for the fourth quarter of 2020 was $29.7 million or $0.59 per diluted share, which included $0.03 per share from LSC and compared to GAAP net income of $27.2 million or $0.51 per diluted share in the third quarter of 2020. The share count used to compute GAAP diluted EPS for the fourth quarter of 2020 was 50.4 million shares, which reflects a reduction in the weighted average share count due to the repurchase of approximately 7.8 million Diodes shares from LSC for the one month since closing. As mentioned in our press release today, we expect the share count for the first quarter to be approximately 45.7 million shares. Non-GAAP adjusted net income for the fourth quarter was $37.3 million or $0.74 per diluted share, which excluded net of tax, $4 million of acquisition-related financing and other acquisition-related costs, $3.3 million of noncash acquisition-related intangibles expense, $2 million of restructuring costs and a $1.7 million gain in the value of certain LSC investments. LSC contributed $0.02 per share to fourth quarter non-GAAP earnings. Non-GAAP adjusted net income in the third quarter of 2020 was $32.8 million or $0.62 per diluted share. Included in the fourth quarter of 2020, GAAP net income and non-GAAP adjusted net income was approximately $5.1 million, net of tax of non-cash share-based compensation expense. Excluding share-based compensation expense, both GAAP earnings per share and non-GAAP adjusted EPS would have increased by $0.10 per diluted share for the fourth quarter of 2020 and $0.09 for the third quarter of 2020. EBITDA for the fourth quarter was $67.1 million or 19.1% of revenue compared to $63.3 million or 20.5% of revenue in the prior quarter. We have included in our earnings release a reconciliation of GAAP net income to non-GAAP adjusted net income, and GAAP net income to EBITDA, which provides additional details. Cash flow generated from operations was $60.8 million for the fourth quarter of 2020. Free cash flow was $33.5 million for the fourth quarter, which includes $27.3 million for capital expenditures. Net cash flow in the fourth quarter was a negative $319.3 million, which included the purchase of Lite-On Semiconductor during the quarter for approximately $453.4 million. Turning to the balance sheet, at the end of the fourth quarter, cash, cash equivalents, restricted cash, plus short-term investments totaled approximately $327 million. Working capital was $514 million and total debt, including long-term and short-term, was $451 million. In terms of inventory, at the end of the fourth quarter, total inventory days decreased to approximately 114 in the quarter on a consolidated basis and 110 days for Diodes only as compared to 120 last quarter. Finished goods inventory days also decreased to 31 from 32 in the third quarter of 2020. Total inventory dollars increased $45.1 million to approximately $305.4 million, which reflects the addition of LSC. Total inventory in the quarter consisted of a $17.1 million increase in work-in-process, a $15.7 million increase in finished goods, and a $12.3 million increase in raw materials. Capital expenditures on a cash basis for the fourth quarter of 2020 were $27.3 million or 7.8% of revenue, which remains within our target model of 5% to 9%. Now turning to our outlook, building on our growth momentum in the fourth quarter and record POS results, we expect revenue in the first quarter of 2021 to increase to approximately $400 million, plus or minus 3%, which represents a record on both an organic and consolidated basis for a combined increase of 14% sequentially at the midpoint. This guidance represents organic growth significantly better than the typical seasonality of sequentially down 5% on average in the same prior two-year periods. We expect GAAP gross margin on a consolidated basis to be 33.6% plus or minus 1%, which includes an approximately 3% impact due to a full quarter of LSC. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related tangible assets, are expected to be approximately 22% of revenue plus or minus 1%. We expect net interest expense to be approximately $3.3 million. Our income tax rate is expected to be 18%, plus or minus 3%. And shares used to calculate diluted EPS for the first quarter are anticipated to be approximately 45.7 million shares. Please note that purchasing accounting adjustments for $3.3 million after tax for Pericom and previous acquisitions are not included in these non-GAAP estimates. With that said, I now turn the call over to Emily Yang.

Thank you, Brett, and good afternoon. In the fourth quarter, revenue increased 13.2% quarter-over-quarter on a consolidated basis and 7.8% organically, which is at the high end of our guidance, primarily due to better-than-expected demand in Asia, followed by North America and Europe. Looking more closely at the fourth quarter revenue, POS revenue reached record levels, which is driving our expectations for continued growth in the first quarter. Distributor inventory in terms of weeks decreased quarter-over-quarter, which is slightly below our defined normal range of 11 to 14 weeks. We expect distributor inventories to return to our normal range in the near term. Looking at global sales in the fourth quarter, Asia represented 81% of revenue; Europe, 11%; and North America, 8%. In terms of our end markets, computing represents 23%, industrial, 23%; consumer, 22% of revenue; communication 20%; and automotive 12% of revenue. We achieved record revenue in the automotive and computing end markets, with computing being driven by record quarterly revenue for our Pericom product. Now let me review the end market in greater details. Starting with automotive, Diodes continues its strong growth momentum, achieving record quarterly revenue and reaching 12% of total revenue. This represents a growth of almost 24% sequentially and 40% year-over-year. There are three application areas where Diodes continue to gain significant traction, including connected driving, which consists of ADAS, telematics, and infotainment systems; comfort, style, and safety, including lighting and brushless DC motors; as well as Powertrain in conventional, hybrid electric vehicles. In connected driving, we saw demand for our new products in infotainment, lighting control systems, speedometers, core alarm systems. More specifically, Diodes automotive-grade switching, TVS, linear diodes, and crystal oscillators contributed to the growth in this application. In comfort, style, and safety, we have strong success with our MOSFET brushless DC motor controllers, Vinex drivers, and bipolar transistors in applications such as daylight running light styling, instrument lighting, as well as gate driver ICs in interior wireless charging. Our LED drivers and power transistors are also gaining market share in this space for hotel light, interior illumination, and exterior lighting applications. Our unipolar hall-effect switch family is also gaining strong market traction for seat belt, seat position, sunroofs, as well as trunk and window openers applications. In vehicle Powertrain, Diodes supplies into conventional internal combustion engine powertrains, as well as for hybrid electric vehicles. Our SBR rectifier has been designed into many of these applications. We have also secured multiple design-ins and opportunities for switching and Zener diodes, rectifiers, and discrete MOSFETs in battery management systems for electric vehicles, as well as emerging applications like mini electric vehicles, micro hybrids, and e-scooter systems. In the industrial market, revenue increased 18% sequentially as we continue to extend our momentum in applications, including solar power inverters, power distribution systems, and smart metering systems, all of which were main contributors in driving growth for our products. We also continue to see strong demand for high-voltage rectified products in smart infrastructure solutions, as well as the adoption of our PCI Express package switch in industrial applications to connect multiple PCIe endpoints with the CPU. Also during the quarter, we began to see increasing new design-ins for LED drivers in UVC lighting applications, as well as numerous design-ins for our YVLDL product family. We also saw rapid growth for our newly released AC-DC converters in LED lighting, e-meters, power tools, and charging applications. Additionally, our series of voltage regulators and SBR devices continue to gain traction in DC fan applications, with the MOSFET demand increasing for both discrete-based inverters and module-based inverters. In the consumer market, shipments for the adapter power IC continued to grow throughout the year. We also saw high demand in the gaming and high-resolution display market, as end users increasingly require high-quality video provided through HDMI and display port. As a result of this trend, our HDMI and display port ReDrivers are gaining traction with key chipset vendor reference design. We're also seeing an increased number of design-ins for our LED drivers, as well as demand for larger monitors continuing to grow. Also in the consumer segment, we continue to see strong interest for our discrete products, including bipolar transistors, ultra-small size transistors, and Schottky barrier diodes in applications like amplifiers, Bluetooth headphones, and drones. Turning to the communication market, wireless communication applications continue to expand, driving revenue generations for Zener TVS diodes in Bluetooth earbuds, smart speakers, and smart lighting, as well as point-to-point and point-to-multipoint links. Our high surge TVS for smartphone power line protection has gained strong growth momentum in new fast charging applications, along with video cameras, access control panels, and audio broadcasting systems. We're also seeing more design-ins and design-wins in mobile phones, cable modems, optical network terminals, 5G CPE routers, radio remote units, and base stations applications for our MOSFET, low saturated, high-voltage transistors, low voltage hall sensors, and RF LDO products. Bipolar junction transistors, SBR, and Schottky products are also gaining traction in applications like 5G outdoor access points, CPE, access point routers, power over ethernet switches, cable modems, WiFi routers, IoT gateways, and mobile battery applications. Lastly, in computing, we reached record quarterly revenue driven by record quarterly revenue for our Pericom products. Due to COVID-19 shelter-in-place orders continuing to drive demand for new and upgraded laptops, tablets, and other related products, we are also seeing strong demand for power management, LDL, hall sensors, AC to DC converters, low switches, and audio amplified products in mobile and monitor applications. ESC protection for USB Type-C in mobile and portable devices also continued to be a strong area for our TVS, SBR, and Schottky products. Also during the quarter, growth momentum continues in server applications along with good momentum in our timing product family to support PCI Express Gen 4 and Gen 5 requirements. This provides flexibility to our customers with seamless migration from PCI Express Gen 4 to PCI Express Gen 5 in the future without changing the timing path design. In summary, we ended 2020 achieving the highest quarterly revenue in the company's history and guided for further growth in the first quarter, both organically and on a consolidated basis, to set the stage for a strong year in 2021. This growth reflects the success we've been achieving with our total solutions sales approach and demand creation efforts to increase the content and share across new and existing customers and applications. We look forward to capitalizing on the synergies and opportunities that Lite-On Semiconductors offers to Diodes across our end markets, product offerings, customers, and manufacturing footprint. With that, we now open the floor to questions. Operator.

Thank you. Our first question comes from the line of Gary Mobley with Wells Fargo.

I wanted to start out by asking some questions about Lite-On, now that you've had a couple of months with the Company under your belt. I know in your prepared remarks, you talked about qualifying some of your existing Diodes products on some of the Lite-On manufacturing facilities, but could you just speak about the timeline for some of the sales synergies to be rung out of the acquisition?

Yes, we are actively qualifying the products in what we refer to as JK Fab. We are nearing completion and expect to finish the qualifications in about a quarter. However, the process for notifying customers and obtaining their approval regarding site changes takes time. We are currently operating at around 50% capacity, and we aim to increase that to about 70% by the end of the third quarter and approximately 80% by year-end, as customer inspections of our changes can be time-consuming.

Right. So Gary, this is Emily. Just to add a little color related to the sales synergy, I think this really depends on the market segment and also the customer qualification schedule. I think for that area of synergy, it's probably going to take somewhere between, I would say, six months in the best scenario to maybe a couple of years, right? So again, it's really down to the market segment and also the customer specifics.

I had a follow-up question regarding Lite-On. Considering that many of your competitors are facing capacity constraints, how could Diodes leverage the underutilized manufacturing capacity at Lite-On, assuming everything goes as planned with the qualifications? More specifically, how feasible will it be for you to capture some market share from competitors who are constrained by capacity?

Okay. Gary, let me address that question. I think overall, right, the current global shortage for semiconductor supply actually helps Diodes, right? If we just look at the fourth quarter, we did have a record revenue with 7.8% sequentially and 10.7% year-over-year growth, which is a strong evidence of our continued success in the product customer expansion initiatives, right? So if we just look at the first quarter guidance, we actually guided 14% quarter-over-quarter growth at the midpoint. And compared to our seasonal slowdown, on average, we talked about in the last two quarters, about a 5% drop. This is again a significant sign of the continued success, right? So we do see some of the constraints. Other than the MOSFETs, we actually see some of the tightness. But what we've been doing is actually aggressively working with the customers to understand their true demand and were able to resolve some of the bottlenecks, right? I think for the MOSFET, we've been very aggressively working with our foundry partners to resolve the out-of-balance problem. At this moment, we are also working on the SFAB to 8-inch expansion as well as the GFAB that we acquired more than a year ago to expand our capacity in both of these fabs. So I think in the longer term, we do have enough fab capacity that is actually again, the GFAB, right? Majority is 8-inch, along with some of the 6-inch fab capacity. And also with the Lite-On Semiconductor acquisition that we recently closed in November, that will also give us additional 6-inch capacity at the JK Fab that Dr. Lu mentioned. So I think with all of this, we are well positioned for our future growth. This really emphasizes the additional business with our internal capacity to support it.

In addition to what Emily is talking about, we are ramping up our Shanghai fab, SFAB, 8-inch capacity in the Shanghai fab.

Thank you. Our next question comes from the line of Matt Ramsay with Cowen.

This is Josh Buchalter on behalf of Matt. Congrats on the great results. I guess, asking the previous question a little differently, are you going to help us understand a little bit how much of the significant above-seasonal first quarter guidance is indeed being driven by you guys being in a pretty unique situation of having some slack in your own internal capacity and able to fill orders that some of your peers aren't?

Well, I think that that's exactly right. Some of that seasonality strength that we have is a couple of things. One, it's the fact that we have capacity that we're continuing to be able to take advantage of through the various avenues, including LSC, GFAB expansion, as well as SFAB. On top of that, it's the continued strength we're seeing across a broad market and actions we've been taking over time to make sure and be prepared for that. So I think it's a blend of those things that allow us to enjoy the above-seasonal growth in the first quarter.

Got it. And then, I guess, given the above seasonal fourth quarter and first quarter, and I realize you're not guiding the full year, but anything you can provide us on visibility into the second quarter and the rest of the year? Or how we should think about the seasonality of the rest of the year? Thanks and congrats again.

So this is Emily. Let me maybe start making a few comments. So we don't usually provide guidance beyond the first quarter. I think Dr. Lu mentioned before, overall, the markets feel extremely dynamic, right? We just need to monitor the situation closely. I think overall, this is not specific to Diodes. I think everybody expects 2021 to be an up market. I think we're definitely not in the position to call the percentage or provide guidance at this moment, but we'll keep you posted as we progress throughout the year.

Thank you. And our next question comes from the line of William Stein with Truist Securities.

Great. Thank you for taking my question. I want to add my congratulations, especially on the very strong Q1 guidance. There's one aspect of it, though, that's a little surprising. The OpEx that you're guiding to looks like it's more than what the stand-alone companies would have delivered combined together, sort of almost a dissynergy. I think Dr. Lu, you've talked about this as related to incremental R&D required, and perhaps that's to qualify the Diodes products on the Lite-On production line. Can you maybe quantify that a little bit on what that investment is? And perhaps as a follow-up, you can talk about what, if any, incremental costs are required to develop the Lite-On portfolio to a level where it's something that you can effectively cross-sell to the heritage Diodes customers? Thank you.

Well, the R&D expense in LSC is lower than the level of Diodes. So, my intention is to increase their R&D to about the same level as Diodes currently has. So that is what I intend to do. Secondly, we need to focus on introducing differentiated types of products. Currently, most of their products are commodity types. My intention is to shift focus and drive the introduction of differentiated types of products using their special technology. What was another question?

I was asking about the effort to cross-sell the Lite-On products into your traditional customer base. I think you had referred to an incremental R&D investment to make that happen. Perhaps you can discuss that a bit. Is it a matter of just proving out the quality of these products to your heritage customers? Or is it in developing new products altogether?

Well, yes. No, but it's not just that. Number one is, I think we are talking about three synergies. We're talking about market synergy because they are very weak in the industrial and automotive market segments. We intend to introduce their products into those market segments. Number two is customer synergies. They typically cannot design into multinational customers, and that's a lot of focus we're going to do to improve the focus and the design-in for those major customers. Number three is the product portfolio. We are focused on solution sales instead of component sales, and that solution sales is adding the product portfolio through different acquisitions inside Diodes in the past. LSC is the ADAS acquisition we had, and we're going to add the product line into our total product portfolios and introduce them into customer solution requirements. Those are the areas we intend to target, in addition to ensuring the qualifications of their products for our major customers, which is just one of the actions we will take, but the key point will be the synergy we're going after.

Thank you. Our next question comes from the line of David Williams with Loop Capital.

Congrats on the quarter and thanks for letting me hop on and ask a question; certainly, I appreciate it. I wanted to ask a little bit about maybe some of the share gains that you're seeing today. And how sticky do you think those may be? Just in terms of picking up new customers from maybe where your competitors have been unable to supply. Do you think that's fairly sticky in terms of those wins? Or do you see a reversal or maybe some of those returning to the competitor as you get capacity constraints begin to fall off?

Right. So David, this is Emily. Let me address that question. Any time there's a market change, it always creates opportunities for Diodes. One of our key focuses is to concentrate on content expansion and customer expansion that we've discussed. I believe new opportunities are opening up for us, which will lead to long-term growth, definitely not short-term. The total solution sales we've been focusing on will help us drive content expansion, as Dr. Lu mentioned earlier. We need to seize opportunities as they arise and ensure we support our customers and build strong relationships. This will lead to long-term business rather than merely short-term interactions.

Okay. And then, maybe in terms of the gross margin, Brett, if you think about how the utilization rates come up in the next couple of quarters. How do you think the gross margin benefits? And when can you get the LSC margin profile maybe closer to the corporate average or maybe the Diode legacy kind of average?

Yes, David, I think that what you'll see, and I think what you'll see in the guide is that we're consistently improving the Diodes organic margin consistent with what we had said. We're basically bringing in the LSC business, consistent with what we had imagined the impact would be. The immediate thing we're working on, as Dr. Lu mentioned a bit, was the qualification of the Diodes products in the LSC factories, which will help the LSC margins. We expect to be able to start making those starts in the middle of the year, which gives us a decent amount of momentum as we come out of the year. The other synergies listed will be more of a multiyear area. The key, as Dr. Lu mentioned, is to invest more in the product line and immediately start getting traction with design-in and design win. Some of those longer lead-time synergies will gain traction quickly, but this is going to be a gradual multiyear effort to align the LSC margins with our expectations for continued growth.

Thank you. Your next question comes from the line of Tristan Gerra with Baird.

Yes, hi, everyone. This is Dustin speaking for Tristan today. For our first question, I know you guys talked earlier about some supply constraints and assets. First, just want to clarify that, that's mostly in automotive. And maybe if you guys can just give an expectation on when the supply constraint may disappear? And then secondarily, are you able to tweak the mix given the tightness? And do you plan on raising ASPs? Then I have a follow-up after.

Right. So let me address that question. I think for the overall shortage in the industry, this is really no surprise, driven a lot by the 8-inch shortage that we've seen, right? So I don't think we're in a position to predict when this effect will be over. What Diodes has been focusing on is actually expanding our internal capacities to support our future growth, right? We talked about the GFAB being acquired over a year ago. By the second half of the year, we're going to ramp up some significant capacity both in 8-inch and 6-inch. Dr. Lu talked a little bit about the SFAB to 8-inch capacity increase as well. With the Lite-On semiconductor acquisition, that increases more 6-inch capacity for us, right? Overall, I think what we focus on is really to position ourselves to support the customers' true demand and continue expanding from that area. So the second question you have is related to the product mix. Changing the product mix and improving margins have been an ongoing focus for Diodes throughout the last few years, and you can definitely see some of the results we have already demonstrated. That will continue to be the focus. We want to continue to focus on driving new products with a better margin profile to support the customers' needs. So that strategy will not change; it fits well with our total solution sales strategy. So again, price increases are definitely not the key focus for Diodes. We really want to work on the product mix improvement as well as total solution sales on demand creation and also contact expansion.

Got it. Great. And obviously, POS has been very strong. I think you guys just said it was a record. Just wondering overall how pricing has been acting recently. And if there have been significant changes maybe you guys could quantify them? And then finally, have you seen any evidence of double ordering at either Tier 1 or Tier 2 customers?

Right. So definitely, in my speech, we had record revenue of POS. We are definitely seeing strong momentum across all the regions, which is the reason we guided a really strong 1Q with 14% growth at the midpoint. When the demand supply, I mean, is getting tight, definitely, we're seeing pricing is holding more firm than before, which is normal for us. I think, again, Diodes' focus is really more on working with customers to understand their true demand so we can provide better support and build long-term relationships with them.

Thank you. I'm showing no further questions. So with that, I'll turn the call back over to Chairman, President and CEO, Dr. Lu for any closing remarks.

Thank you for your participation on today's call. Operator, you may now disconnect.
