Thank you, Ben.

We will now review our financial results for Q4 2020. Please note that financial results will be presented on a GAAP basis unless we designate otherwise. The non-GAAP result is crude stock-based compensation expense, one-time charges, non-recurring gains and losses. Our full GAAP results are available in our press release that was issued earlier today. GAAP revenue in the fourth quarter of 2020 was $23.2 million. Gap net income in the fourth quarter of 2020 was $4.4 million. If we exclude stock-based compensation of $364,000, net gain recognized on long-term investment of $133,000 and one-time paycheck protection program, $604,000, the non-gap net income will be $4 million. Gap net income per fully diluted ADS in the fourth quarter of 2020 was $0.14. Non-gap net income per fully diluted ADS was $0.13. Gross margin was 51.3% in Q4. The gross margin reflects the current revenue level and the product mix. R&D expense. was $3.8 million or 16.4% of revenue. This amount is growth stock-based compensation expense of $80,000. SC&A expense was $4.1 million or 17.7% of revenue. This amount is growth stock-based compensation expense of $284,000. The non-operating income was $920,000. Income tax was $215,000 in the fourth quarter and it mainly reflected the actual tax provisions on each taxable location. In Q4 2020, there was no stock repurchase. Q4 2020, revenue by end market breaks down into the following percentages. Consumer was 41 to 43% of revenue. Computer was 2 to 4% of revenue. Industrial was 53 to 55% of revenue. Communications was almost zero. At this moment, I would like to provide some additional information. O2 Micro finished the first quarter with $47.8 million in unrestricted cash and short-term investment. This represents cash and cash equivalents of $1.76 per ADS. In addition, O2 Micro has no debt. Account receivable at the end of Q4 was $16.4 million. is 64 days. DSO is more than 60 days mainly from account meets. Inventory was $12.6 million at the end of the fourth quarter. This represents 101 days of inventory and inventory turns was 3.6 times in Q4. Net cash generated from operating activities in the fourth quarter was about 5.6 million. Capital expenditure was about 1.2 million in the first quarter for R&D and IT equipment. Depreciation and amortization was 981,000 in Q4. At the end of the fourth quarter of 2020, O2 Micro had 303 employees 56% of which are engineers. Based on current market situation and the best updated managerial rolling forecast, the company has the following guidance for Q1 2021. Next revenues are expected to be down 4% to up 6%. Product gross margin expected to be in the range of 50% to 52%. R&D expenses, excluding stock-based compensation, are expected to be in the range of $4 million to $4.5 million. SG&A expenses, excluding stock-based compensation, are expected to be in the range of $4.1 million to $4.6 million. Stock-based compensation should be in the range of $450,000 to $550,000. Non-operating income expected to be in the range of $200,000 to $300,000, excluding foreign exchange gains or losses. Income tax expense expected to be in the range of $200,000 to $300,000. The goal of our management team and the board of directors is to maximize shareholder value. We have accomplished this by taking the necessary steps, which included managing operating expenses and monetizing assets on the balance sheet. In regards to our share repurchase program, we have been active in this program historically. Since 2002, we have repurchased over 20.3 million ADS shares for $101.3 million. As of the end of Q4, we had $7.6 million remaining in our share buyback authorization. In 2021, there are many dynamic factors associated in the business development. We will carefully plan and execute to target revenue growth and maintain growth margin in the first half of 2021. First is to continue to invest in new product while allocating some resources for the second source development for the capacity support. And to invest in-house R&D testing center and buy more advanced testers for testing capacity required for advanced ICs in both the lighting and the battery management product group. We also monitor the supply chains tightly and have added all in process to support the dynamic demand for multiple end market timing. In Q4 2020, 424,000 shares of EMC were sold and about 1.6 million cash in. The average selling price of EMC in Q4 is around $3.9 per shares, with original cost of 53 cents per share. All EMC shares were sold by end of November 2020. The initial investment in EMC was about $1,960,000 in 2010, and the net exit total cash received was $12.9 million from Q3 2018 to Q4 2020. Returns to shareholders are very much on our minds and will continue to be a focus in the future. We will provide updates to the additional measures to enhance shareholders' value throughout this year. Given the uncertain demand and the macro environment, we are prepared to continue to manage costs as needed. Although we believe we have a high current cost based on current and anticipated revenue levels. I would like to thank everyone for participating and turn the call over to Jim to talk more about our business. Jim, please.

Thank you, Perry. Good morning, everyone. We were pleased with our Q4 2020 results and expect Q1 2021 revenues to remain strong despite Chinese New Year holidays that will result in some interruptions in product flow from our supply chain partners. We would note that Q1 2021 revenue projections are up over 40% from Q1 of 2020 and over 75% from Q1 of 2019. This ongoing revenue growth reflects the strength in market position of both our intelligent lighting and battery management product lines. Our ongoing revenue growth and profitability continue to be driven by several factors. First, our product groups have successfully developed next generation patented products that appeal to top tier and brand name OEMs that we now proudly call customers. Secondly, our company's market focus of developing energy efficient products that enhance mobility was thrust into the limelight with COVID-19 pandemic. It immediately increased demand for mobility based products and help drive our company revenues upward as markets we serve experience a surging demand from several factors, including employees being equipped to work from home with computers and monitors, remote learning that increase sales of tablets, notebooks, and monitors, stay-at-home regulations that increase sales of high-end TVs, high-end monitors for gaming, battery-managed garden equipment, power tools, and vacuum cleaners. COVID-19 hospitalizations that increased sales of advanced monitors for diagnosis. Travel restraints and social distancing that led to an upsurge in the sale of e-bikes. Although vaccines may return part of our lives to normal, much of that new normal will include increased work from home, education from home, and higher performance home entertainment systems. Battery-managed power tools, vacuum cleaners, garden tools, e-bikes, and e-vehicles will continue to expand in usage. The pandemic will have lasting impact on the way we live as increased mobility is here to stay. We would add that our rapidly expanding revenues would not have been possible without our disciplined and dedicated operations team that worked tirelessly to overcome many COVID-19 obstacles to keep product flowing from wafer fabs to assembly to test with shipment onward to our customers. Finally, I will make some abbreviated remarks about our product lines. Our Intelligent Lighting product line enjoyed excellent growth throughout calendar 2020. This was the result of our many design wins that include both 4K and 8K TV and expansion of HDR monitors into gaming, medical, and industrial applications, along with expanded home usage. While we have a leading position in higher-end products for TVs and monitors, we have not ignored our overall market share and continue to expand design activity in lower-end TV and monitor products using our patented, highly energy-efficient backlighting products with integrated MOSFETs. This market positioning is expected to enable our ongoing growth. Additionally, our intelligent lighting R&D efforts in the industrial and automotive lighting have enabled ongoing progress in design wins. This includes advanced products for robotics and autonomous driving applications where we continue to have good product acceptance. While these design wins take longer to generate revenue, We believe this will help enable long-term growth of our intelligent lighting group. Our battery management product line had excellent growth throughout calendar 2020, driven by the expansion of our design wins with major OEMs and power tools, e-bikes, e-vehicles, vacuum cleaners, garden tools, and energy storage systems. As previously noted, our battery management products include arm-based microcontroller technology, for market applications where some of our existing customers need more sophisticated battery management. This has enabled us to engage with higher end customers, including those in the rapidly growing energy storage market. Customers are moving forward to design our arm-based battery management products into their next generation high performance systems. We continue to file battery management patent claims for our new products to protect both our company and our customers' market positions. Our major customer list includes to grow, it includes Bissell, Black & Decker, Dyson, Electrolux, Lexi, LG, Akita, Murata, Panasonic, Philips, Samsung, Shark, and TTI. I will now turn the call over to our CEO Sterling for closing remarks.

Thank you.

I'm sorry, Sterling, we're not able to hear you. You may be muted.

Yeah, thanks, Jim. O2 Micro reported the fourth quarter 2020 revenue of $23.2 million. Revenue was up 4.5% from the previous quarter and up 30.1% from the same quarter prior year. The gross margin in the fourth quarter of 2020 was 51.3%. The gross margin was down from 51.8% of previous quarter which is in our company average range. Our revenue is in line with the guidance publicly released on October 30, 2020. Our major growth driver, Intelligent Lighting Group's high-end 4K, 8K, local dimming backlight product, has another strong growth quarter. It came from the rising demands of all sectors, including TV, monitor, tablet, and mobile computers. The mini-LED is the trend for the next advanced technology, which offers 100 times of its package style compared to the conventional package LED. It means the same local dimming unit area could be deployed 100 times more mini-LED unit versus conventional LED package style. Therefore, the panel pixel HDR achieves much more fine resolution with a much higher contrast ratio. We see this first deployment happening in a tablet or smaller size professional monitor as initial high cost. We expect the mini-LED calls will be closed down in the coming years. Our new multi-scan LED backlight ICs for the LCD display is further effective for mini-LED logo dimming. The multi-scan could be a combination of two-scan, four-scan, all the way up to 32 scales. It reduces motion, burr, and so-called halo effect and optimized weight. With the multi-scale local dimming technology being applied to the mini-LED, the experience of the panel display improves, the crystal ability when the object moves fast. In general, the customers spend more time at home, work from home, education from home, or virtual meeting, conference, even concert from home. It drives two factors. The growing number of the TV or monitor, as well as the high quality of the TV and monitor, where the business grows. The global 4K TV market size is expected to reach the U.S. $380 billion by 2025, and the compound annual growth rate 21.2%, according to some reports. We also see our factory product revenue grow strongly at all sectors, such as Colex, The flow cap products, the cordless household appliance, interrupt power system, battery storage system, and so on. With the energy density improved, the battery management IC require higher resolution for voltage current and accurate temperature measurement. Our analog front end and our base management unit were designed embedded with 14-bit high-accuracy AD converter build-up sigma could really meet the customer needs. In some example, we could reach 15 millivolt resolution performance, which is way beyond the customer expectation. Regarding the power-to-market potential, the project will grow from the US $30 billion in 2020 to $36 billion by 2025. The key factor in the growth of this industrial market, including the increasing adoption of coatless power tools, rising demand for the fossil tool in industrial environment, and a growing construction industry emerging economy. Neating iron battery sales dropped 90% from 2010 to 2019, nine years. Meanwhile, the Neating Iron Battery product base grew 15 times from 2010 to 2020, within 10 years, 15 times. Furthermore, the Leading Island Bellator industry expert also forecast the sale manufacturer capacity will grow another five times to 2030. So we continue to grow the business despite the dynamic market situation. We are optimistic for the fundamental of our business, We focus on high-margin and high-performance business as well as outreach expense management in order to create the best return for shareholders. We always keep the shareholder's best interest in mind, especially in a current dynamic situation. At this moment, thank you for listening to our conference call and turn back to Dan, please.

Thank you, Shirley. Agra, at this point, we'd like to open the call to questions.

Thank you. If you would like to ask a question, please press star 1 on your telephone keypad. If you're using a speakerphone, please make sure your mute function is turned off to allow your signal to reach the equipment. Again, that is star 1. We'll go first to Tor Spanward at Stifel.

Thank you and congratulations on the results. First question, you didn't talk a whole lot about capacity and supply. Obviously, there's a lot of constraints out there right now in the industry. So, could you maybe talk a little bit about, you know, how your company's positioned in regards to capacity?

So, Kerry, do you want to address that? Yes, Kerry. Sherwin, do you want to address it? Yeah, Kerry, please.

Regarding the capacity here, we are continuously working on the incremental increase. We do get a very good support from our vendors for our long-term focus already released to the vendor. So for this area, actually, we get a very good support as well. Also, we can see that we are very stable in process. in the inventory area to support the Q1, and we continue to see this trend. And for the incremental area, I think the two areas that we continue to work with our vendors, our foundry partner, and also the back end, is actually our product, enjoy longer product life cycle, and also a good high performance area. So this is actually kind of the a good area that we can continue to work with our vendors to get the capacity. However, the flexibility is not so big as in 2020. So in 2021, we may continue to see this kind of growth as we mentioned through the quarters. Also, we are continuing to invest in our testers to enhance our testing capacity to support our spatial IC which is requiring more testing time. So this is the update from this area. So Sterling may probably comment on this area too.

So for a little detail, for the bottleneck of testing, we moved our IC across the multiple types of testers to testing it. And as Perry also mentioned, we came back to acquire some new testers. And they're arriving, and some of them go to the consign. Some of them, we have our small probe to testing those, the hot item, popular item. So for the packaging, the strategy we did is we tried to find out the third source or fourth source for the packaging, the bottleneck. And we are lucky to find a few of the qualified, appropriate alternative across the Taiwan and China. And for the wafer, we should be careful to work with our customer for the forecast. And meanwhile, some of the long-term high-volume one, we're also looking for internal second source for the alternative of the foundry. So these are three levels we are doing. Very good.

And I assume you're probably 100% booked. Are you experiencing any delinquencies at all, or are your customers able to get what they need?

Well, I think some of the glitches always happen because nowadays people like to get more inventory. And so far, we are working very close with our customer. Some of the IT, 100%, but some is not. And we internally sometimes accommodate some of the capacity the supplier providing. We are able to meet the requirement of the customer with a very tight schedule. And the one thing I'd like to point out, Doc, due to the dynamic situation, though, so the supply feasibility is reduced. So we have been working day to night to make sure. those are low visibility and try to meet the customer request date. So that's very time consuming and keep us very busy.

Very good. Last question. You referred a few times to battery storage as an opportunity or a market you continue to sell into. Is that basically the sort of consumer battery packs or are you doing something beyond that perhaps in the industrial or auto area as well?

The answer to that is yes, we are doing work in the industrial area, Tori.

Okay, very good. So that would basically be for things like power tools and things like that?

Yes, and solar storage, that kind of situation.

Got it.

Perfect. Thank you. Congratulations on the results.

Thank you.

And we'll go next to Lisa Thompson at Zacks Investment Research.

Good morning. So I have a few questions on how things are going. First, can you talk a little bit about the battery management business? What's your feeling about the growth rate this year versus 2020? Is it going to continue or is it going to accelerate because you're in more areas now?

Yes, we actually expect very dynamic growth this year because, as Sterling mentioned in his portion of the call, we continue to see the cost of the lithium ion come down. And as that has occurred, it's really important dramatically expanded the market. So we really see growing opportunities in all of these areas and we've really seen acceleration of movement away from the traditional power cord over to battery managed products. As I mentioned on my portion of the call, one of the areas where there is very significant growth that has historically not been there is the whole e-bike area. because we've seen with the COVID-19 situation, many countries begin to limit activity in terms of driving, and we see more and more people turn to e-bikes. Also, many countries and major cities are limiting their car traffic downtown while they're opening up things for bikes, including shared e-bikes, and many of those at this point are growing very rapidly. So we certainly have the opportunity to grow the battery management at a pace that's possibly higher than last year.

Great. Actually, this leads right into my second question. So I was going to ask you about e-bikes. Could you get a little bit more specific as to what products you're selling to that market and which – person, an entity are you selling it to? Is it the component people or the people who make the bikes themselves? And then contrast that with what might sell into any vehicle as you move up. And also throw in kind of the value of what goes into a bike versus the value of what goes into a car.

Throwing you a lot of...

Yes. So these ask many questions. So let's take it one by one. So the bike, the SHIELD bike is an electrical bike that we are focused. And the battery pack is an immediate customer for us, a battery pack manufacturer. Normally, they pack about 10 to 14 battery cells. Average is about 14 cells. and some even go to 17 cell, depends on how heavy weight of the bike want to go, how far the distance. And for those 14 or 17 or 10 cell, they're packed together, and the most concerning will be the life of the battery pack, and that's even by the unbalance of the battery, and also external environment, which we call ambient temperature. And that effect of temperature, voltage, and the current. So need very precise ICs to tell which cell of these 14 cell or 17 cell has been in low capacity or low quality. And then do certain corresponding action, including the balance or do certain after the bleeding for the battery cell. So our part is decided two portion. One is major temperature voltage in the current. And we can, now, you look at when the battery is still from the 10 to 14 to 17. So every time you measure one cell, and as your number of the cell growing, so the measurement, the time should be very fast. And also the measuring, the resolution should be sensitive. So we can do... they're leading the AD converter to achieve that goal. As I mentioned, we can do resolution 15 mini volt, and that's very key because when the battery cell go to the CV mode, the CC mode, the constant current and then the constant voltage from the CC to the CV. So the voltage variation is very limited. and that you need to tell very minor the difference of your voltage go up or go down. Second, it's the current. The current was most identified as a safety issue when you have a short circuit or a cell, and that had to be responding very quickly because any one cell of the 17 or 14 has an issue, and you need to scan the most you have scanned 17 times to reach that particular programmatic cell. So the responding time is also verified. So one of the factors is the AD converter responding time, the shortage cycle. So these two makers are the major choice for the battery-packed company for the electrical bike. Now, as you just can imagine, we have also some customers. From the battery-packed customer, they also sell to a light electrical vehicle not to the full size electric vehicle, and studies maybe they need more cluster of the battery pack. But go to the fuel car, we have a few customer utilize our battery pack, which is using our IC inside. So that's the transportation. And then go to the downward, and you can looking at like a scooter, like the other two-wheel, or three-wheel personal transportation. But for those sectors, their battery cell is not as high as like a 14 or 17 cell. Our advanced technology ICs may not be showing that particular advantage, so our market is still focused on the electric bike. And they not only do the domestic in China use, they do the cell or share bike, And they also export to many places in the world, including, as Jim indicated, Europe also has a major marketplace. They're shipping those electric bikes, and that could be holding and selling themselves. Thank you.

Okay. So what's like the pricing that you would sell to a bike versus to a scooter? Is it the same product for the same amount of money? because the bigger vehicles get charged more.

Yes, we have a DMU, we have AFE, then we have DFE, and so all these different product lines, we have four cells, we call the four cells, five cells, that's one group, and we have seven cells, 10 cells, 14, and 17 cells. So each product, we have all the different combinations of the ICs because their voltage is different. So that's the higher voltage one, higher sale one, higher sale number IC is always more expensive because it's different technology to do it.

Okay, great. That makes sense. So back to the numbers now, I mean, the fact that you're having a sequentially up first quarter is very exciting because I don't remember that ever happening before. It's usually the horrible quarter. So could we expect them sequentially each quarter will be improving this year?

Well, we certainly hope to because you're right. Traditionally, you actually see some pullback in late December and then a softer market in Q1 due to the TV in particular. That market tends to be lower in that timeframe. However, what we've seen this year is, and by the way, some of the major TV manufacturers have seen those trends, But nevertheless, we have other markets, including the battery management market, that has continued to grow our revenue through that normal downtrend. So basically, we do see the opportunity to continue to grow quarter to quarter. That's what we certainly hope to see. And that's, I think, as Perry and Sterling mentioned, we are, in fact, buying testers and really getting prepared for higher level demands.

That's great. And so the only other difference I see is it looks like you might be spending a little bit more than you did in 2020 based on what you're saying for the first quarter. And that should continue?

Perry? Any thoughts? Perry? Perry?

I have some noise here, so can you ask again? Sorry.

It looks like that you might be spending more than last year just based on what you're saying about Q1. Is that accurate as far as operating expenses?

Yes. I think that there are some features. Of course, the variable one could be proportional to the increase of the revenue. So this would probably only be a smaller amount increase in the outtakes. And the second is actually a result from the weakened US dollar. Our theory here is paid by local currency, let me be Japanese yen, Korean won, and also NT dollar. So we can probably result in some increases in OPEX. Also, I expect there's some of the increase in the freight for the delivery. And also, I do expect some traveling in the second half of 2021. It's probably we can get back some traveling. However, I think that the total OPEX rate will be lower than last year.

The dollar amount will be lower?

The percentage.

Oh, the percent. Okay.

The percentage will be lower than the last year.

Great. All right. Well, I know Dan is happy to hear about the increased travel. So at least that.

There you go.

There you go. Okay, great. Thanks. That's all my questions.

Great. Thank you. And that does conclude the question and answer session. I'd like to turn the call back over to Dan for any closing remarks.

Thank you all for your time and attention this morning. Please feel free to contact me at 408-987-5920 extension 8888 or at IR at o2micro.com with any follow-up questions. Have a great day and thank you again for your time and attention. Goodbye, everyone.

And that does conclude today's conference.
