Thanks, Steve, and thank you to everyone for joining us today. As we close out 2021, I'd like to summarize some of our key accomplishments. In October, we celebrated our IPO within seven years of founding. We believe a record for any power semiconductor company and the result of intensive focus to establish Navitas as the clear technology and market leader in gallium nitride or GaN power ICs. GaN is a next generation power semiconductor with up to 20 times faster operation and our GaN fast power ICs deliver 3x more power and 3x faster charging in half the size and weight and with up to 40% energy savings compared to traditional silicon chips. In 2021, annual revenues doubled to nearly 24 million with Q4 revenue growing sequentially by over 30%. At the end of 21, our cumulative unit shipments increased to over 35 million units with zero GAN-related field failures. While Q1 will see slightly lower revenue compared to Q4 given expected seasonality, we anticipate sequential growth in Q2 of greater than 50% as we expect multiple major new Tier 1 Gantt Charger launches ramping significantly next quarter. In total, we continue to forecast another doubling of annual revenues for this year. Our gross margins improved in 2021 by over 10 points year-on-year as all customers adopted our Generation 2 in the first half and started ramp of our Generation 3 late in the year, both of which offered Navitas and our customers significant performance improvements and cost reductions. For 2022, we will see the impact of the TSMC 20% wafer price increase, which will limit our margin expansion in the year, while we look forward to our Generation 4 ramp in the second half of 2022, which will fuel our margin expansion into 2023. Taking a closer look at some of these new technology developments, Generation 3 with GANsense technology integrates critical sensing circuits monolithically into GAN for the first time in our industry. Generation 3 unlocks another 10% of energy savings while adding important new protection circuits to set a new standard and reliability. Already in mass production with Lenovo, Xiaomi, Vivo, among others, Gansense was honored last month in Las Vegas with a CES 2022 Innovation Award. Gansense is also a key enabler in the new exciting ultra-fast charger category. Hot on the heels of Generation 3, we have Generation 4, which will start sampling next quarter. This will bring further gains in energy savings and cost reduction, and we will give further details when that technology is fully launched later in the year. With all of these developments in mind, our patent portfolio now totals over 145 patents pending or issued, reinforcing strong competitive protection for our multi-year lead in GAN IC technology. Our high-power progress continued with two new industry firsts, GAN design centers dedicated to data center and to electric vehicles. And I'm excited to announce today two other industry firsts. We have just published the industry's only sustainability report dedicated to quantifying the positive impact GAN is having on decarbonization and on conserving our planet's natural resources. In addition, today we're announcing the industry's first 20-year warranty for our GAN ICs. I'll explain more about some of these new developments later, but let me first give you an update on our mobile charger business. At the end of 21, the number of customer chargers released to production increased 75% from the prior year, reaching an all-time high of 171. In addition, we have doubled our design pipeline compared to the prior year, with a new high of over 240 customer projects now in development with the vast majority of those expected to launch throughout the year. We announced a new strategic partnership with Anchor, a leader in aftermarket fast chargers with a number of GaN chargers already announced and many more in development. In addition to strong adoption in the aftermarket and accessory chargers, our tier one inbox charger introductions doubled in 21 compared to 2020. That list now includes Xiaomi, Vivo, Motorola, Dell, LG, among others. We also announced a new category of ultra-fast chargers, which delivers over 100 watts of power using our latest GANsense technology to charge smartphones from zero to 100% in less than 20 minutes. This high power rating in this new category requires an additional PFC circuit, so two GAN power ICs are needed roughly doubling the GaN revenue opportunity per charger. Xiaomi was the first GaN fast launch in this new category with their Note 11 Pro Plus, and now Vivo has followed with their IQ9. We expect several others to join this exciting new product category later in the year. And today, we are very excited to announce a major win at a Tier 1 Korean smartphone customer. While we can't share further details until that customer makes more of a public announcement This is a major step forward in the adoption of GaN across all major mobile players in smartphones, tablets, and laptops. In fact, with this new announcement, we are now in mass production with eight out of the top 10 mobile players. And when considering customer projects in development, Navitas GaN technology has now been adopted by all of the top 10 mobile players. Next, let me share a few important updates on our market expansion plans. In Q4, as expected, we started sampling our higher power GaN ICs that are targeted for data center, solar, and electric vehicles. Our GaN IC technology is unique compared to our GaN discrete competitors as we integrate one or more power devices along with analog circuits that includes drive, control, sensing, and protection. This monolithic integration is essential to unlock the full system benefits of GaN by eliminating parasitics, increasing operating frequencies, reducing the size, weight, and cost of both passive and mechanical components, and maximizing the energy savings while reducing system costs. These benefits are actually magnified as our GAN ICs are applied to higher power applications, such as the ones we target in data center solar and EV. As a consequence, the customer response to these new higher power GAN ICs has been extraordinary, and we now have dozens of customer engagements well underway towards adopting our GAN technologies. To support and accelerate this customer adoption, we announced the opening of two new design centers to drive GAN adoption for data centers and for electric vehicles. We believe both of these design centers are a first for our industry and a key ingredient in our unique company strategy to co-develop GAN based power systems with our customers in each of our target markets. We have staffed these design centers with impressive industry recognized technical leaders and engineering teams that have a proven and unique set of capabilities to develop disruptive next-generation GAN-based power systems in each of our target markets. These teams are equipped with advanced tools along with the technical skills that span all hardware and software needs across power architectures, passive component optimization, thermal mechanical design, EMI mitigation, and system cost and manufacturability considerations. Last week, Navitas was the first company to publish a sustainability report that comprehensively quantifies the positive impact of GaN power semiconductors on climate change based on global standards. To share some highlights from the report, GaN power ICs have up to 10 times smaller CO2 footprint compared to silicon equivalents. Each GaN power IC shipped saves four kilograms of CO2 and can reduce customers' carbon footprints for example, by up to 30% savings for a 65-watt laptop adapter. Based on third-party reports, adopting GAN in electric vehicles could accelerate EV adoption by up to three years and eliminate 20% of road sector CO2 emissions by 2050. It is estimated that GAN could save 2.6 gigatons of CO2 per year by 2050, the critical timeframe of the Paris Accord. You can expect to see much more on this front as we look to take a leadership role across the entire semiconductor industry in accelerating the electrification of our world. In terms of quality and reliability, Navitas is already leading the industry by shipping a cumulative total of over 35 million units without a single reported GAN-related field failure, and we have also completed over 5.8 billion device hours of testing. Given harsh electrical and environmental conditions and the critical need to avoid power failures, which could shut down entire systems, we are pleased to announce another significant development, the industry's first 20-year product warranty. This warranty is unprecedented in our power semiconductor industry and reflects our commitment and confidence in the quality and reliability of our highly protected and integrated GAN ICs. This 20-year warranty supports our plans to extend the lifetime of mobile chargers and consumer power adapters, thereby further reducing waste and CO2 emissions, and is also an essential confidence factor and differentiator for NAVACOS as we look to enable GAN-based data centers, solar installations, and electric vehicles. You'll see us roll out this warranty across all of our GAN-IC product range in the coming weeks. Before I turn it over to Todd to discuss the financials in more detail, I want to summarize the many exciting industry-first achievements that we've announced recently or in today's earnings call. The first power semiconductor supplier to reach an IPO in seven years from its founding. The first to monolithically integrate sensing capabilities in GAN. The first GAN company to penetrate 10 of the top 10 mobile players. The first GAN company to reach 35 million units shipped and to do it with no GAN-related field failures. the first 20-year power semiconductor product warranty, the first design centers for GAN dedicated to data center and EV, and the first sustainability report dedicated to quantifying GAN's positive impact. And now, over to Todd Glickman, our CFO.
Steve
Thanks Gene, and thanks everyone for joining us today. Let me take you through our fourth quarter numbers and guidance for Q1 and 2022. Gap revenue for the quarter grew to $7.3 million, representing 30% sequential growth from the third quarter of 2021. For the full year, we grew revenue to $23.7 million, which represents year-over-year growth of 100%. Mobile demand remained strong throughout the year, despite the fact that our GAN revenue growth was limited in the second half due to our customer supply chain constraints of non-GAN-related components. Non-GAAP gross margin was 44.3% in the fourth quarter, up from 37.7% in the same quarter of the prior year. For fiscal year 2021, we grew non-GAAP gross margin to 45.4% from 33.2%, which is consistent with our strategy to deliver attractive margin expansion while passing along cost reduction to our customers. With regard to expenses, we have grown our sales and marketing teams to support our rapid growth in the mobile market and our expansion into data center, solar, and EV. We have also invested in legal and accounting infrastructure needed to be a successful public company. Taken together, we have increased our non-GAAP SG&A expense from 3.7 million in the fourth quarter of 2020 to 4.2 million in Q4 of 2021. Non-GAAP R&D expense grew to $6 million in the fourth quarter of 2021 compared to $4.5 million in Q4 2020 as we continued developing multiple new generations of GAN ICs and we developed and delivered new high-powered GAN ICs for data center, solar, and EV. Putting all this together, non-GAAP net loss from operations was $6.9 million compared to a net loss from operations of $6.3 million in the fourth quarter of 2020, as we are in a heavy investment mode in this rapid growth phase of our company. Turning to the balance sheet. Cash and cash equivalents were $268 million. Inventory was $12 million compared to $11.7 million in the prior quarter as we maintain healthy inventories to support short lead times and significant growth and upside opportunities with our customers. Moving on to guidance. For the first quarter of 2022, GAAP revenues are expected to be between $6 and $7 million compared to $5.3 million in the first quarter of 2021. Last year, in the first quarter, we sold our first inbox GAN chargers, which mitigated what would traditionally have been a seasonally lower quarter. For this year and in future years, we expect Q1 to be seasonally similar or lower than Q4. Q2 is expected to be a significant growth quarter with many spring customer product launches propelling at least 50% sequential growth from the first quarter. I'd also like to mention that we have posted an Excel spreadsheet showing our historical quarterly financials and the seasonality you can see in 2020. As previously indicated, full-year revenue is expected to double from 2021 to $48 million. Gap and non-gap gross margin is expected to be approximately 44% plus or minus 1% in the first quarter and for the full year of 2022. TSNC's 20% wafer price increase announced late last year is leading to a 6% gross margin reduction that is factored into our Q1 and full year guidance. As Gene mentioned, we will launch Generation 4, which will fuel margin expansion into 2023. Our long-term strategy and expectation to achieve system cost parity with silicon in 2023 and deliver 55% gross margins long-term is unchanged. In total, our non-GAAP operating expenses in Q1 are expected to be approximately $13 million, which excludes stock-based compensation and amortization of intangible assets. Full-year non-GAAP operating expenses are expected to be approximately $58 million, which includes a full year of expenses associated with being a public company. Finally, we expect our basic and diluted share count in Q1 to be between $120 and $124 million. The majority of our shares outstanding are held by major shareholders and executive management and are currently subject to lockups expiring on or before October 2022 and October 2024 respectively. In summary, 2021 was a pivotal year for Novitas. We doubled our revenues and expanded our non-GAAP gross margins by over 12%. In addition, we have invested in the next generation technology and needed infrastructure that will allow us to achieve our expansion and scalability goals for 2022 and beyond. Gene and I are now ready to take your questions. Operator, let's begin the Q&A session.
Operator
Thank you. As a reminder, to ask a question, you will need to press star 1 on your telephone. To withdraw your question, press the pound key. Please stand by while we compile the Q&A roster. Our first question comes from the line of Ross Seymour of Deutsche Bank. Your line is open.
Ross Seymour
Hi, guys. Thanks for letting me ask a question. Gene, I wanted to talk first about the supply side of the equation. Last quarter, you mentioned that that probably cost you a million units. Has that gotten better? Is that still a headwind as you look forward into the first half of this year? Just any update there would be helpful.
Stephen Oliver
Sure. Definitely, Ross. Thanks for asking the question and joining us. We don't see a short-term significant impact based on the guidance. We think our customers have adequately factored that into their forecasts as of now and looking forward in the year. And if anything, we see a little progress because we have worked with our customers to approve some of the additional suppliers for the non-GAN components, which creates some flexibility for them. So it seems like the trends are moving in the right direction, and we think we've factored in any of those constraints on a go-forward basis.
Ross Seymour
Thanks for that, Cullen. I guess as my follow-up, just switching over to the margin side of things, I think everybody's well aware of the wafer price increases that the foundries have passed through. Can you just talk a little bit about the magnitude of the offset when you get to Gen 3 and Gen 4 I know it's a couple years out, so it doesn't have to be precise guidance, but Todd, you mentioned that your 55% target is unchanged. If we got a little bit of linearity between the 44 and the 55 target, any sort of stair-step-up timing that we really need to be cognizant of?
Stephen Oliver
You know, I would add we're ramping Generation 3 now. There's sort of an offset between the Generation 3 cost reduction and the TSMC price increase that results in being kind of margin neutral, as we said, sort of flat into this year from Q4, Gen 4 kind of restarts that margin expansion. We'll start sampling that in Q2, and that'll ramp in the latter part of the year, and I think ultimately result in nice margin expansion into 23. And I think then we could sort of look at that stair step, as you said, or that linear extrapolation towards the 55% longer-term goal.
Operator
Perfect. Thank you.
Stephen Oliver
Thanks, Ross.
Operator
Thank you. Our next question comes from Tristan Guerra of Baird. Your line is open.
Tristan Guerra
Hi, this is Tyler on for Tristan. Thank you for taking my questions. Starting off, what engagements or joint ventures do you have in China that you can talk about, and how is China part of your market share plans, given the power charger supply chain there?
Stephen Oliver
Yeah, thanks, Tyler. Good question. Certainly, China has been fundamental to our strategy from the start, largely almost half or 40% of our company footprint is in China. We have an extraordinarily strong local team there, not just in sales and technical support, FAE, but multiple design centers there, both developing GAN chips as well as developing GAN-based power systems. The design centers I mentioned actually, mobile was our first one, which is centered there supporting customers around the world, but even our data center and our newest EV design center is there. It's a very strong team. Those are not formal joint ventures or partnerships per se, but internal capabilities. And that sets us up to really strong, uh, form a strong customer partnership with all the key customers, not only in China, um, but globally. So we're at a really strong spot there in China.
Tristan Guerra
Great. And then for my followup in 2020, you shipped about 11 million units into smartphones. What was that figure for 2021?
Stephen Oliver
2021 unit shipments. Do we have an estimate?
Stephen Oliver
The end of 20 was 6.5. The end of 21 was 35.
Stephen Oliver
Yeah, so close to 25 million. Let's say north of 20 million units is our estimate.
Tristan Guerra
Awesome. I appreciate you taking my questions. Thank you, Tyler.
Operator
Thank you. Our next question comes from Kevin Cassidy of Rosenblatt Security. Your line is open.
Kevin Cassidy
Thanks for taking my question. You had mentioned the fast charging, the less than 20 minutes takes two power ICs. What percentage of designs that you're working on will be using that?
Stephen Oliver
Hi, Kevin. Thanks for the question. Ultra-fast charging, obviously a big deal there. We're talking about over 100 watts. Anything north of 65 watts actually requires that power factor correction, extra circuit, thereby doubling the likely gain content. We didn't break it out in any specific detail, but it's certainly the fastest-growing part of the fast charger market, and there's certainly many designs coming. The first was Xiaomi, as I mentioned, Vivo It's already recently launched, and obviously we can't talk about the specific customers coming out before they're public, but it is a fast-growing percentage, and there's many new designs in that category to launch later this year.
Kevin Cassidy
Okay, great. And as you look at the design centers for data center and EV, what's the product roadmap that you'll be introducing for those markets or customers? What timeframe, I guess, would you expect to see significant revenue?
Stephen Oliver
Yeah, good question. So, data center, we actually announced late last year, and we've already launched our first sort of system-level prototype that acts as a reference design as well as a demonstrator to all of those data center customers to show them what's possible in GAN. From there, we'll quickly expand into different power levels, different form factors, and next-generation versions that keeps pushing the energy savings. So we're well on our way to the customer engagements and delivering those exciting new GAN-based platforms. EV is just starting out. We announced it in January. We're in the process of building out the team, building out the lab. We'll have the core team and core lab in place in Q2. We'll have initial prototypes of onboard chargers, and that's our first application focus. There's many applications in EV, as you know, but we'll start with onboard chargers using our GAN technology. And we'll have that available as a prototype or a platform to demonstrate to our key customers in the second half of this year.
Kevin Cassidy
Great. Thank you.
Stephen Oliver
Thanks, Kevin.
Operator
Thank you. Our next question comes from Quinn Bolton of Needleman Company. Your line is open.
Quinn
Hey, guys. Congratulations on the results and the nice outlook for 2022. I guess I wanted to start there. it sounds like you feel pretty good that the supply chain is starting to improve. But I guess, you know, looking at the doubling in revenue, if I just do some quick math, it sort of implies, you know, on average, maybe $3.5 million of sequential revenue growth, you know, each quarter to get to that sort of $48 million level for the year. Is that the right way to be thinking about how you see the business? Is it sort of a linear increase across the four quarters of the year? Do you see sort of a you know, a different revenue pattern into the second half.
Steve
Great. Thanks, Quinn. I appreciate the question. It's a great question. You know, when you're looking at our business on a quarterly basis, I think the best way to look at it is to look back at 2020 to look at our seasonality. We do expect the first half of the year to be around 30%, while the second half will be 70% of our total year revenue.
Quinn
Got it. But 2020 is a good proxy for what you might see as normal seasonality in the business.
Stephen Oliver
That's correct. Yeah, 21, I'll just add, 21 is a little unusual because we had a major new launch, the Xiaomi 55-watt inbox in December, which is not a common time to launch, and that carried through into significant rivers in Q1, making it a little bit non-traditional or non-typical in terms of seasonality, so as Todd described earlier. 20 is a little bit better way to look at it, and they give you good guidance on how to expect to ramp this year.
Quinn
Ken, and then just a longer-term question on gross margins, following Ross's question. You know, it looks like the data center and solar products are sort of on track to ramp in calendar 23, just as you're starting to see the benefits of the fourth-generation technology, the mobile, and perhaps the consumer segments. And so I'm wondering... You know, do you see pretty good progress as all of that begins to contribute in 2023, or are there headwinds to margins that we should be thinking about out in next year?
Stephen Oliver
Yeah, I think there are two dynamics, as you point out. One is market expansion. We generally expect improved higher margins in the higher power markets, data centers, solar, and EV markets. At the same time, we think our generational improvements, even in the mobile space, are going to continue to incrementally expand margins while offering cost reduction to our customers. So I think we'll benefit in 23 and beyond by both of those dynamics, ultimately combining together to achieve that longer-term goal of 55%. Great.
Quinn
And then last for Eugene, maybe a more technical question, but you talked about as you go up in power to 65 watts and above, you need to add that power factor correction stage, which adds a second opportunity for GAN IC. I'm wondering if you can talk about, are you seeing a transition in architectures from like flyback to active clamp that may further increase the GAN content in some of those higher power applications, or does active clamp architecture really play more in either data center or some of the consumer chargers?
Stephen Oliver
Yeah, no, it's a great question. A very good observation. In fact, around a hundred Watts, we see most commonly a single GAN chip in the PFC and a single GAN chip in the traditional flyback, what's called a QR flyback. Actually, as you push that power level up and you want the energy efficiency to go up, say at 120, 150 Watts, even 200 Watts, which is a crazy amount of power to be pumping into smartphones and mobile devices. But that's exactly where we're headed. And you can imagine how fast the charging's going to be. But as you do that, you can actually benefit from a second GAN switch in the PFC circuit and a second GAN switch in the second stage, the flyback stage. And as you alluded to, there are alternative topologies beyond QR, which only uses a single GAN switch, whether it's active clamp flyback, LLC, or some other variations of those two that both employ two GAN switches. So we're really headed towards One to two, to then to three, and then eventually four GAN switches as we keep pushing the power, the fast charging, and the energy efficiency higher and higher. Great. Thank you, Gene. Thanks, Quinn.
Operator
Thank you. Our next question comes from Blake Friedman of Bank of America. Please go ahead.
Blake Friedman
Hi, thanks for taking my question. Just a quick one on with consumer products expected to ramp throughout this year and data center and solar markets ramping in 2023, I was just curious if you can provide any color on how we should think about cash burn through this year as well as any color in the next year.
Stephen Oliver
Can we clarify first, Blake, were you looking for a further definition on what sort of things are ramping in the markets or more interested in the financial part of your question, cash flow?
Blake Friedman
More interested in the financial part.
Stephen Oliver
Sure.
Steve
Yeah, thanks, Blake, for the question. So we finished the year at around $268 million in cash. With a doubling of our revenue and OpEx of $58 million on a non-GAAP basis for 2022, we do expect to use around $40 million of our cash on our balance sheet, leaving us plenty of cash to put to work on strategic and other partnerships in the future.
Blake Friedman
Got it. Sounds good. And then actually just kind of drilling down more on the kind of consumer opportunities ramping this year. Just curious if you can highlight in what areas of the consumer market you are beginning to see early traction and maybe what percentage of revenues this year can come from the consumer markets.
Stephen Oliver
And Blake, when you mentioned consumer, are you lumping in mobile into that or consumer somehow separate from mobile?
Blake Friedman
Yes, separate from mobile.
Stephen Oliver
Yeah. The predominant part of our Revenue forecast this year is definitely dominated by mobile. That's fast chargers for phones, tablets, laptops, and frankly, the aftermarket, which could be charging anything that uses a USB-C output. With that said, we also see this year as the start of the non-mobile consumer, as you're alluding to, things that don't have a battery. You're not carrying the charger around. But actually, they still care about power delivery, energy savings, size, and weight. We have pointed to two in the past, two promising areas that we'll be launching and ramping this year. One is in LED TV. Another is in traditional desktop PCs and PC-related peripherals. We don't have any announcements yet on those, but as those products come to market, we'll share more details about them. There will be a small percentage of that total, but that is a promising and a really important multibillion-dollar opportunity beyond mobile into the broader consumer adapter space.
Blake Friedman
Sounds good. Thank you.
Stephen Oliver
Thanks, Blake.
Operator
Thank you. Once again, to ask a question, please press star 1 on your touch-tone telephone. Again, that's star 1 on your touch-tone telephone to ask a question. Our next question comes from the line of Natalia Winkler of Jefferies. Your question, please.
spk00
Hi, Gene, Todd. So I think a question is to you, and I wanted to just dive in a little bit more in the gross margin throughout the year. I appreciate kind of how it stacks up longer term, but as we think through the year, can you please kind of walk us through the different dynamics with inbox and aftermarket types of revenues, and how should we think about the gross margins for the year?
Steve
Sure. So that's a great question. Let me start with the gross margin. So we finished Q4 at 44%. We are guiding to Q1 at 44% as well, so flat. and that's driven by the TSMC price increase. We believe the full year will be at 44%, but you can look at the margins with the understanding that Gen 4 is coming out in the second half of the year, so we do expect a little bump there. So knowing that in mind, you'd be in a better position to determine your margins on a quarter-to-quarter basis.
spk00
Understood. That's very helpful. Thank you. And I guess the second question is sort of a similar one for the OPEX. So is it going to be stepping gradually over the year or is it going to be a significant decrease, you know, sequentially into the second quarter and then more linear?
Steve
So it's more on the stepping gradually throughout the year as we add headcount. along with develop new products into the market, so a small step up each quarter throughout the year to hit the eventual $58 million for full-year OpEx.
spk00
Understood. Thank you. That's very helpful.
Operator
Thank you. At this time, I'd like to turn the call back over to Gene Sheridan for closing remarks. Sir?
Stephen Oliver
