Thank you, Leanne. Welcome, everyone, and thank you for joining us today.

I'm pleased to report record performance in 2022 with revenue growth of 10.8% over 2021. Even when considering the COVID-related lockdowns and power outages throughout the year in China, as well as the global economic slowdown. In fact, the fourth quarter represented our ninth consecutive quarter of year-over-year growth. Additionally, our earnings power and cash generation in 2022 were also significantly highlighted with a gross margin expansion of 420 basis points to 41.3%.

Operating margin expanded 510 basis points to 20.4%, and GAAP EPS increased 44% to $7.20, and non-GAAP EPS grew 42% to $7.36. We also achieved a record cash flow from operations of $393 million. Underpinning the Company's noteworthy performance was continued strong growth in our automotive end market, which increased 40% over 2021 and reached 15% of product revenue for the year. We also continued to drive growth in our industrial end market through our ongoing content expansion efforts, which contributed to our industrial and automotive end markets representing 42% of product revenue and exceeding our target model of 40%. The growth in those end markets combined with the ongoing increase of our Pericom products also contributed to our strong gross margin expansion throughout the year as part of our product mix improvement efforts.

Reaching the $2 billion revenue level in 2022 was a significant and meaningful achievement of the entire Diodes team. With the gross profit growing 23% to $827 million for the year, we have taken another giant step towards the next goal in our 2025 financial targets to achieve $1 billion in annual gross profit. I am very proud of our accomplishments and our ability to consistently deliver both top-line growth and significantly expand earnings for our shareholders.

With that, let me now turn the call over to Brett to discuss our fourth quarter and full-year financial results and our first quarter 2023 guidance in more detail.

Brett Whitmire - Chief Financial Officer

Thanks, Dr. Lu, and good afternoon, everyone.

Revenue for the fourth quarter 2022 was $496.2 million, increasing 3.3% from $480.2 million in the fourth quarter 2021 and down 4.8% from the $521.3 million in the third quarter 2022. Full-year 2022 revenue grew to a record $2 billion, an increase of 10.8% over the $1.8 billion in 2021. Gross profit for the fourth quarter was $206.2 million or 41.6% of revenue, increasing from $190.7 million or 39.7% of revenue in the prior year quarter and down from $217.8 million or 41.8% of revenue in the prior quarter. For the full year, GAAP gross profit was a record $827.2 million, a 23.4% increase over 2021, and GAAP gross margin improved 420 basis points to a record 41.3%.

GAAP operating expenses for the fourth quarter were $109.7 million or 22.1% of revenue, and on a non-GAAP basis were $105.9 million or 21.3% of revenue, which excludes $3.8 million of amortization of acquisition-related intangible asset expenses. This compares to GAAP operating expenses in the fourth quarter 2021 of $104.7 million or 21.8% of revenue. And in the third quarter 2022 of $105.4 million or 20.2% of revenue. Non-GAAP operating expenses in the prior quarter were $101.3 million or 19.4% of revenue. Total other expense amounted to approximately $1.7 million for the quarter, consisting of $490,000 of other income, $2.9 million in interest expense, a $400,000 foreign currency loss, and $1.1 million of interest income.

Income before taxes and noncontrolling interest in the fourth quarter 2022 was $94.8 million compared to $108.8 million in the prior year quarter and $109.1 million in the previous quarter. Turning to income taxes, our effective income tax rate for the fourth quarter was approximately 1.5%, which includes taxes related to non-GAAP items. On a non-GAAP basis, the tax rate for the fourth quarter was approximately 18.7%, and for the full year 2022, the non-GAAP tax rate was approximately 18.5%.

GAAP net income for the fourth quarter 2022 was $92.1 million or $2 per diluted share compared to $65.5 million or $1.43 per diluted share in the fourth quarter 2021, and $86.4 million or $1.88 per diluted share in the third quarter 2022. For the full year, 2022, GAAP net income was a record $331.3 million or a record $7.20 per diluted share, which was approximately 45% increase from the $228.8 million or $5 per diluted share in 2021. The share count used to compute GAAP diluted EPS for the fourth quarter 2022 was 46.1 million shares, and 46 million shares for the full year. Non-GAAP adjusted net income in the fourth quarter was $79.6 million or $1.73 per diluted share, which excluded net of tax $3.1 million of acquisition-related intangible asset costs. This compares to $73.3 million or $1.60 per diluted share in the fourth quarter 2021, and $92 million or $2 per diluted share in the prior quarter.

For the full year, non-GAAP adjusted net income was a record $339 million or a record $7.36 per diluted share, an increase of approximately 43% from the $237.2 million or $5.18 per diluted share in 2021. Excluding non-cash share-based compensation expense of $7.6 million net of tax for the fourth quarter and $28.7 million for the full year, both GAAP earnings per share and non-GAAP adjusted EPS would have increased by $0.16 and $0.62 per diluted share respectively.

EBITDA for the fourth quarter was $129.6 million or 26.1% of revenue compared to $139 million or 28.9% of revenue in the fourth quarter 2021, and $141.9 million or 27.2% of revenue in the prior quarter. We had a gain on an investment in the fourth quarter of 2021 that benefited EBITDA in that quarter. For the full year, EBITDA improved 19.7% to a record $520.4 million or 26% of revenue compared to $434.6 million or 24.1% of revenue in 2021. 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 $102.9 million for the fourth quarter and a record $392.5 million for 2022. Free cash flow was $39.1 million, which included $63.8 million for capital expenditures, and for the full year, free cash flow was $180.8 million, including $211.7 million for capex. Net cash flow was a negative $44.7 million including the pay down of $114.1 million of total debt. And for the full year, net cash flow was a negative $25.7 million, which includes the net paydown of $112.3 million of total debt.

Turning to the balance sheet at the end of the fourth quarter, cash, cash equivalents, restricted cash plus short-term investments totaled approximately $348 million. Working capital was $729 million and total debt, including long-term and short-term, was $186 million. In terms of inventory, at the end of the fourth quarter, total inventory days were approximately 117 as compared to 113 last quarter. Finished goods inventory days were 33 compared to 32 last quarter. Total inventory dollars decreased $14.5 million from the prior quarter to approximately $360.3 million. Total inventory in the quarter consisted of a $12.1 million decrease in finished goods, a $3.2 million decrease in raw materials, and a $0.7 million increase in work in process.

Capital expenditures on a cash basis were $63.8 million for the fourth quarter and for the full year, approximately $211.7 million or 10.6% of revenue. Full-year capex was higher than our target model due to targeted expansion of our JK wafer fab and Hsinchu Science Park in Taiwan. Without this investment, we would have been within our target model of 5% to 9% and we expect to remain in this range this year.

Now turning to our outlook. For the first quarter of 2023, we expect revenue to be approximately $467 million plus or minus 3%. GAAP gross margin is expected to be 41.0% plus or minus 1%. Even with the revenue and loading decrease in the first quarter, we expect to maintain our gross margin effectively comparable to the last quarter and above our target model of 40%. Non-GAAP operating expenses, which are GAAP operating expenses, adjusted for amortization of acquisition-related intangible assets are expected to be approximately 22.2% of revenue, plus or minus 1%. We expect net interest expense to be approximately $2.5 million. Our income tax rate is expected to be 19% plus or minus 3% and shares used to calculate EPS for the first quarter are anticipated to be approximately $46.5 million. Not included in these non-GAAP estimates is an amortization of $3.1 million after-tax for previous acquisitions.

With that said, I will now turn the call over to Emily Yang.

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Thank you, Brett, and good afternoon.

As Dr. Lu and Brett mentioned, 2022 was a record year for Diodes across all financial metrics. Fourth quarter revenue was down 4.8% sequentially, which is above the midpoint of our guidance and slightly better than our typical seasonality. Looking more closely at the fourth quarter revenue, POS was a record in Europe. Distributor inventory in terms of weeks increased quarter-over-quarter, which is higher than our normal defined normal range of 11 to 14 weeks. This increase is due mainly to demand softness in China related to COVID and our anticipation of COVID recovery in Q2 as well as our anticipation of labor shortage around Chinese New Year. We positioned more products to minimize the potential impact and quick response once the market recovers. Overall, demand and backlog remain stable across all regions, especially for automotive, and industrial end markets.

Looking at global sales in the fourth quarter. Asia represented 73% of revenue, Europe 15%, and North America 12%. In terms of our end markets, industrial represented 28% of Diodes product revenue computing 23%, consumer 18%, communication 14%, and our automotive end market reached a record 17% of the product revenue. Our automotive and industrial end combined totaled 45% of product revenue for the quarter, which is 5 percentage points above our 2025 target and above 40% for the fourth consecutive quarter. This further demonstrates Diodes' ability to quickly adjust our capacity allocation from low NPC consumer and smartphone segments to high-demand end markets like automotive and industrial.

Now, let me review the end market in greater detail. Our automotive market continued to be a highlight for both the quarter and the full year. Setting revenue records for the tenth consecutive quarter and growing 40% in 2022. Our consistent strong growth in this market can be contributed to our ongoing demand creation efforts as well as market share gain across new and existing customers. Our design win momentum continued in our three application focus areas of connected driving, comfort style, and safety and electrification. In connected driving, we continue to see increased interest in USB Type C read drivers, Analog Switches, Diode controllers, LDOs, DC-DC Buck converters, Zener diodes, and TVS in the rear seat entertainment. ADAS, infotainment, smart cockpit, telematics, and instrument cluster applications. We also saw increased designing for video switches used in EP DisplayPort and USB Switches in telematics communication systems by multiple customers.

In comfort style and safety, our Linear LED Drivers and DC-DC Buck converters were designed into next-generation LED lighting applications. Our Sensors business grew significantly driven by applications including electronic steering, control lock, refilling covers, window lifters, and water pumps. High voltage Switching diodes and Zener diodes also grew in the quarter primarily in the air quality sensors and HVAC applications. Several of our SBR Automotive product was designed into battery-powered electric vehicles and slugging hybrid vehicles for automotive safety applications.

We also secured a number of new design wins for USB charging controllers for in-vehicle USB charging devices. Lastly, in the electrification, our 32-bit IO extenders were designed into the EV vehicles control unit and our TVS product is designed into a high-speed data line for e-vehicle displays and electric vehicles. Our protection products also have strong growth in applications, including lean battery controls, and onboard diagnosing systems. Additionally, we ramped up our MOSFET product in multiple new applications across several different customers while releasing a number of low voltage MOSFET products for the Battery Management System and WiFi application.

In our industrial market, revenue also set other records representing the sixth consecutive quarter of growth. Our PCIe 3.0 Packet Switch continue to gain traction in industrial automation applications as they enable and enhance the performance by connecting SOCs and CPUs to the endpoint. Additionally, our high voltage but industrial IoT devices experienced very strong demand for smart electric meters. Similarly, our LED controllers ramp up in the LED power supply for Power Industrial commercial LED lighting, and our industrial sensor business continues to gain traction in power tools, air condition, DC motors, and washing machine applications.

Additionally, we continue to secure design wins for our CIS products in AOI applications like battery film, PCB, wafer inspection, and check scanners. Also our Switching diodes Zener diodes fast recovery rectifiers and LED drivers have been helping to support smart, efficient, green factory automation applications including utility metering, industrial sensors, cameras, scanners, elevators, and image processing equipment. Diodes SBR product is also being widely used in power over use and while MOSFET attractions in new power applications.

In the computing market, despite the softness in low NPC applications, our momentum for SBR, TVS, MOSFET, and current monitoring products continue in the notebook and tablet designs. We secure numerous design wins for i3 CE Switches, SM bus Level Shifters, analog switching, IO extenders, and TVS in the cloud surfer protection applications. Additionally, our EDP read drivers, EDP marks and 20-gigabit per second DP2.0 read drivers are being adopted in the gaming notebooks and in graphics card applications.

In the communication market, our USB Type C audio switches, IO extenders, MOSFET, and hall effect switches, continue to be designed into a series of smartphone devices, while our LED drivers were designed into mobile phone peripheral products including wireless chargers also our Shockey product was designed into 5G WiFi application and will continue to see traction for our PCI Express clock buffers family in 5G CPE designs and TVS product in networking applications.

Lastly, in the consumer market, we saw increased adoption of our 12-bit high-speed MUX in the embedded multimedia card modules and our current limit power switches, continue to see solid demand from USB power applications in gaming consoles are 8-hour 1 tan gigabit bi-directional retimers will also adapt to cable applications, and our TVS protection products, USB switches, SBR SP products, and USB power delivery decoders will design into security key, fourth cameras, next-generation televisions, wearables, and portable as well as wall-mounted USB C power socket applications.

In summary, Diodes' achievement of record results in 2022 once again highlighted the ongoing success of our customer expansion initiatives as well as our focus on product mix improvement towards higher margin products and end markets to drive increased profitability. Our significant expansion and growth in the automotive, industrial end market is a direct result of the strategic. We look forward to further expanding our momentum and continuing to progress in the coming year.

With that, we now open the floor to questions. Operator?

Question & Answers

Operator

[Operator Instructions] Today's first question comes from William Stein with Truist. Please go ahead.

William Stein - Truist Securities - Analyst

Great. Thank you for taking my question. I'm hoping you can review the channel inventory trends. Again, I think you mentioned it briefly in the prepared remarks, but I just want to - I want to hear the clarification as to what happened in the channel in the quarter and what you expect will happen in the current quarter and distribution. Thank you.

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Hi Will, this is Emily. Let me answer this question. Right. So, I didn't mention the channel inventory was up quarter-over-quarter is a little bit higher than our normal range at this moment. But with, I mean the main reason due to this change is actually a couple of things. We definitely see China's softness during the COVID in the fourth quarter and then we also have an anticipation of recovery from some of the like CCCs that we talked before, they started some of the channel inventory rebalancing for the last few quarters. So, there is an anticipation of that recovery, as well as there is a labor shortage during the Chinese New Year time frame. So, with all these dynamic situations combined, so we actually also strategically increase some of the channel inventory so that where we can better support the customers last minute or demand change.

William Stein - Truist Securities - Analyst

Thank you. And can you talk about your outlook by end market for the coming quarter?

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Yeah, sure. I think, automotive, we're still seeing a lot of - a lot of strength overall. Our pipeline continue to grow, our engagement continue to enrich, and if I just look at the whole year or quarter-over-quarter comparison, automotive is still a record quarter for us by the end of Q4. And if we look at the whole year, year-over-year growth is still 40% plus. Right? So, that's really, really exciting. And therefore industrial, I think it's a little bit mixed there are certain end applications softer than the others, we also are seeing some inventory rebalancing going on, but when we take everything together, I would say still a really stable end market at this moment.

And then computing, we talked about the inventory rebalancing probably started the beginning of Q3 last year. So, we're still seeing a softness going on, but we also like I mentioned, there is an anticipation of recovering probably in a quarter or two. Right? Consumer, we still see some softness, especially from the China market. And then on the communication side on the start - smartphone, I think still inventory rebalancing is still ongoing. But again, right, so once they get to a certain level, we do expect some recovery.

William Stein - Truist Securities - Analyst

It sounds like an ongoing - it sounds like a similar trend in the coming quarter relative to what we've seen over the last quarter or two. If we can - Is that correct, we shouldn't interpret any divergent performance during pivot in Q1 relative to what we've seen in Q4.

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Yeah. So, I would say there is no significant change from the end market point of view, but the key thing for us is continue to focus on our product mix improvement. Right? Continue to leverage our capacity to lower the support for these low-end markets and focus on supporting the strong demand for end markets like automotive, as well as industrial applications. Right?

William Stein - Truist Securities - Analyst

Great. I'll get back in queue. Thank you.

Operator

The next question comes from Matt Ramsay with Cowen. Please go ahead.

Joshua Buchalter - Cowen - Analyst

Hi, this is Josh Buchalter on behalf of Matt. Congrats on the stellar results. And thank you for taking my question. I wanted to follow up on Will's question. So if I'm understanding correctly the channel is running above their typical 11 to 14-week range. And so, I know you're taking factory loadings down. But does that mean you're sort of comfortable running above the typical range for a little while in anticipation of the recovery? I just want to make sure I'm understanding correctly. Thank you.

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Yeah. I think, Josh, I did mention a little bit earlier. Right? There is still a lot of dynamic situation going on with the labor shortage during the Chinese New Year, the softness due to the COVID especially in China as well as anticipation of some recovery probably around the Q2 quarter. So, with all this combination of the situation, we are actually okay with the inventory - channel inventory, higher than our defined normal range. The other end that we look at as the quality of inventory, right? So, it's not only about the number of weeks on the shelf is also the quality of the product on the shelf. So, we actually feel very confident stand behind the numbers.

Joshua Buchalter - Cowen - Analyst

Okay, understood. Thank you. And I guess for my follow-up, I wanted to ask about gross margins. It sounds sort of only marginally despite two straight quarters of mid-single-digit revenue declines. And it sounds like lower factory loadings as well. Can you walk through what's driving so much resiliency on your gross margin line, is it mix shift between end markets or products that you continued strength in the pricing environment? Any color there would be super helpful. Thank you.

Emily Yang - Senior Vice President, Worldwide Sales & Marketing

Yeah, definitely, it's a really good question. Right? So, if you look at for the last few years, we really emphasize on two things. One is actually the total solution sales. The second thing is really product mix initiative or improvement overall. Right? So, we openly talked about automotive industrial is a key focus for us. And if you look at the result, right, I had mentioned earlier, just automotive, we achieved 40% year-over-year growth. And then with think from 2013 to 2022, we compounded annual growth rate more than 30%. So definitely is a great success and the consistency is actually definitely worth mentioning.

I think with industrial again, it's actually the biggest segment. By the end of Q4 is actually 28% of our total end market out of the products. Right? So, with the auto, and industrial combined based on the Q4 results actually 45% of our total revenue even with the whole year, that actually represented a 42%. So, we openly talk about by the end of 2017, we provided guidance for this segment is actually we want to achieve about 40% as you can see we have four quarters consistently above this target. So, again, this is a really good demonstration of the product mix improvement initiative.

The other good example is actually Pericom product family. Right? So, we've been talking about the margin overall is really, really attractive. And again, we consistently deliver the growth of this market - product segments. Right. So, with the combined, you can actually see even with the revenue guide it's slightly down around seasonality for Q1, but our margin guidance, 41% still significantly higher than our 2013 model that we establish of 40%. So, I hope you can actually see this is actually a really strong demonstration of our focus of product mix improvement. Of course, it coupled with our manufacturing efficiency, which is always the strength of the company. So, I think with all combined together, we actually confident that we are on the road, right track, and right path towards our 2025 defined goal, which is $1 billion gross profit and $2.5 billion revenue model, right, so.

Joshua Buchalter - Cowen - Analyst

No. Super helpful and congratulations again on the results.
