Before we begin, I want to note that shortly following the close of market today, we issued a press release reporting financial results for the Q4 and fiscal year of 2021. This information is available on the investor relations portion of our website at axt.com. I would now like to turn the call over to Gary Fischer for a review of our Q4 and fiscal 2021 results. Gary?
Thank you, Leslie, and good afternoon, everyone. As a reminder, in response to investor requests and to align with our peers, as well as to provide better clarity on our operational and financial results, we will be providing both GAAP and non-GAAP financial results. Non-GAAP results exclude stock-based compensation. Investors can find the GAAP to non-GAAP reconciliation tables in our earnings announcement. Today, we are pleased to report that total revenue for the Q4 of 2021 was $37.7 million, up 9% from $34.6 million in the third quarter of 2021, and up 40% from $27.0 million in the Q4 of 2020. Q4 marks our eighth consecutive quarter of growth and highlights the market expansion and increasing demand for our indium phosphide and gallium arsenide substrates.
To break down our Q4 2021 revenue for you by product category, indium phosphide was $13.1 million, gallium arsenide was $11.3 million, germanium was $4.2 million, and revenue from our two consolidated raw material joint venture companies was $9.1 million. In the Q4, revenue from Asia Pacific was 74.9%, Europe was 16.7%, and North America was 8.4%. Again, in Q4, no customers reached 10% of revenue, and the top five customers generated approximately 29% of total revenue. Our continued revenue diversity demonstrates that our growth is not overly dependent on one large customer or application. This is another factor contributing to our confidence that our growth has reached a point of sustainability and will continue throughout 2022.
Non-GAAP gross margin in the Q4 was 32.4% compared with 33.8% in Q3 of 2021 and 34.0% in Q4 of 2020. For those who prefer to track results on a GAAP basis, gross margin in the Q4 was 32.2% compared with 33.3% in Q3 of 2021 and 33.9% in Q4 of 2020. Our gross margin came in slightly lower than the prior quarter. Contributing factors were increasing raw material costs within a constrained environment of demand, lower yields in some of our products, and a decision to accept strategic lower margin business in order to position ourselves competitively in advantageous markets and customers.
These factors offset the improvements made to gross margin at Tongmei from expiring contracts, as well as a new and promising raw material recycling program that Morris will comment on shortly. Gross margin improvement is a top priority for AXT in 2022. Like most businesses, we have seen a steady increase in costs relating to everything from wages to the materials required to manufacture our products. Those increases will likely continue to create some near-term offset in 2022. However, we think we can get back to 35% range this year. Improvement will come through growing volume, favorable product mix, better pricing, and a strong focus on yield improvements and manufacturing efficiencies. We also believe that we will see some incremental gross margin improvements as Tongmei continues to work through some of the contracts that began creating a headwind in Q3.
Total non-GAAP operating expense in Q4 was $8.1 million. This compares with $7.7 million in Q3 of 2021 and with $6.6 million in Q4 of 2020. On a GAAP basis, total operating expense was sequentially flat at $9.1 million. For comparison, total GAAP operating expense was $7.2 million in Q4 of 2020. R&D remains one of the primary drivers of the increase in our OpEx. We have two major programs that are ongoing, the development of six-inch indium phosphide and the development of eight-inch gallium arsenide. Non-GAAP operating profit for the Q4 of 2021 was $4.1 million compared with the non-GAAP operating profit of Q3 in 2021 of $4.0 million and $2.6 million in Q4 of 2020.
For reference, GAAP operating profit for the Q4 of 2021 was $3.0 million, up from an operating profit of $2.4 million in Q3 of 2021 and an operating profit of $1.9 million in Q4 of 2020. Non-operating other income and expense for the Q4 of 2021 was a net loss of $100,000. The full breakdown is in our press release. For Q4 of 2021, we had a non-GAAP net income of $4.1 million or $0.09 per share, compared with $5.4 million or $0.13 per share in the third quarter of 2021. Keep in mind that the third quarter results included two local government grants totaling $1 million, which did not repeat in Q4.
Non-GAAP net income in Q4 of 2020 was $2.8 million or $0.06 per share. On a GAAP basis, net income in Q4 was $3.0 million or $0.07 per share. By comparison, net income was $3.8 million or $0.09 per share in the third quarter of 2021 and $2.1 million or $0.05 per share in Q4 of 2020. The weighted average diluted shares outstanding in Q4 of 2021 was 42.8 million. Cash equivalents and investments were $51.8 million as of December 31. By comparison, at September 30, they were $56.0 million. Depreciation and amortization in the Q4 was $2.0 million and capital investments were $10.5 million. Total stock comp was $1.1 million.
Net inventory at December 31 was $65.9 million. Okay, this concludes the discussion of the quarterly financial results. Now let me briefly highlight the total year of 2021, which is a fun part of my presentation because a lot of good things happened. For the fiscal year of 2021, revenue was $137.4 million, up more than 44% from $95.4 million in fiscal year 2020. It is important to note that this growth is all organic, driven by market expansion and market share gains. In 2021, we grew in every revenue category across our portfolio without the help of price increases. This underscores the momentum we are seeing in our business with new applications coming to the market, major technology trends, and our own success in winning share at strategic customers.
Gross margin for the fiscal year 2021 on a non-GAAP basis was 34.8% compared with the 31.9% for fiscal year 2020. GAAP gross margin for 2021 was 34.5% compared with 31.7% for fiscal year 2020. Net income for the fiscal year of 2021 on a non-GAAP basis was $19.1 million or $0.44 per diluted share, compared with a net income of $5.9 million or $0.14 per share for fiscal year 2020. This represents a more than 350% improvement in profitability and underscores the significant shift in our business over the last twelve months.
GAAP net income for fiscal year 2021 was $14.6 million or $0.34 per diluted share, compared with a net income of $3.2 million or $0.07 per share for fiscal year 2020. I'll now give you a brief update on our plan to list our subsidiary, Tongmei, in China on the STAR Market in Shanghai. We are very pleased to announce last month that Tongmei submitted a formal application to list its shares and initial public offering on the Shanghai Stock Exchange. The application was submitted in December and was formally accepted for review on January 10. The review of our application is now underway, and we have received our initial comment letter. As we have discussed, the process of going public on the STAR Market includes several periods of review and therefore is a lengthy process.
Tongmei does not expect to complete the IPO until the second half of 2022. Okay, that completes my comments, and I'd like to turn the call over now to Dr. Morris Young for a review of our business and markets. Morris?
Thank you, Gary, and good afternoon, everybody. 2021 marked a significant turning point in our business. As Gary mentioned, we grew 44% in a single year and more than 65% over our 2019 revenue results. We believe that we are hitting an inflection point in which applications that were once considered bleeding edge are now coming to market for more mainstream adoption. Across our portfolio, we're working with customers for new innovations, helping to rethink what is possible, advancing specialty materials into areas the market might not have conceived of just a few years ago. To prepare for this growth and opportunity, we have modernized AXT into a supplier capable of meeting the requirement of tier one customers. Over the last 4 years, we successfully relocated and expanded our facilities with 3 world-class locations. We upgraded our business and manufacturing systems and processes.
We grew our supply chain for critical materials, and we invested in both our technology roadmap and our customer success. The growth you're seeing in our business is a result, not just one or two quarters of success, but 8 consecutive quarters of increasing revenue with historically low customer churn. In 2021, our indium phosphide business grew by 41% and is now our single largest revenue contributor. Gallium arsenide substrates grew by 38%, driven by a wide variety of applications. Germanium substrate grew by 18%. As Gary said, our increase in revenue is organic. It comes from an expansion of our markets, from our own market share gains, and strategic customer wins, all of which have a long-term growth opportunity still to come. In 2022, we expect continued momentum in indium phosphide-based optical applications for telecom and data center modernization.
5G is a big driver, alongside a more general global investment in the infrastructure required to support massive increases in data creation and flow. Indium phosphide-based devices will play an increasingly important role in next generation infrastructure, and AXT is well-placed to support it. We also expect 2022 to be the year that indium phosphide comes to consumer applications in a consequential way. We were very pleased to begin ramping a design win in for a short wave infrared proximity sensor. Sensors of this type can detect substances such as water, sugar, and alcohol. They typically can measure not only heart rate, blood oxygen level, and also proximity to skin and other surfaces. In the future, sensors of this type may be able to measure blood glucose, blood lipid, and blood alcohol level, and others.
As such, we're excited about this design win, and we believe it represented a gateway to other designs and applications in portable consumer devices. This win also underscores the breadth of applications that indium phosphide enables, and we believe there are several more new ones on the horizon, from health monitoring to automotive sensors to the Metaverse. We expect these applications will be driven by tier one players. Their emergence over time could dramatically increase the addressable market for indium phosphide. As it is with current applications and design wins success, we believe we will grow our indium phosphide revenue in 2022 by 35%-40%. We also believe that significant groundwork will be laid in 2022 for new applications in gallium arsenide.
We're already seeing healthy growth in high-end LEDs, solid-state industrial lasers, and Wi-Fi for IoT applications, which we expect will continue. Recently, we have also seen demand for gallium arsenide substrate for power amplifier in 5G handsets. This is a new market for us and one that is opening up to AXT as a result of both the increased power amplifier counts in 5G handsets, as well as the supply constraint at our competitors to meet customer needs. Though the gross margin profile on this application is lower than other areas of our business, the volume opportunity is attractive, and we believe we can drive healthy gross margin contribution in our business model in the coming years. In addition, we're seeing what feels like a record amount of development activities for new applications ranging from health monitoring to laser-based sensors and more.
Of course, in the next several years, microLEDs could very well drive enough volume to reshape the gallium arsenide industry entirely. As we look into the years ahead, there are numerous applications that will continue to drive our results. They're not just coming, they're here, and we are creating substantial, sustainable, and profitable growth opportunities across our business. With that in mind, a top priority for AXT in 2022 is customer success. We're highly focused on ensuring that we can keep pace with current and future customer requirements. Given the constrained environment, customers are more openly communicating their long-term needs, providing us better visibility so that we can scale accordingly. We believe that our ability to add capacity quickly and cost effectively is another major competitive advantage for AXT and is a key reason for our design win success to date.
Yet another top priority for me in 2022 is gross margin improvement. As Gary mentioned, there are numerous things that we're doing to drive lower cost, better yields, greater manufacturing efficiencies. One of the program that holds longer term promise is a new recycling effort for indium phosphide. Through our own internal research and development effort, we have invented a highly advanced process to recycle in single crystal indium phosphide material. This is significant because our manufacturing process generate a fair amount of excess material that has real value, but until now has not been reusable. Going forward, we'll be able to reclaim this material, which will help us lower our costs, increases our supply, and create a meaningful ESG program to reduce waste. Finally, in 2022, we're highly focused on driving our development of large diameter substrates.
These are major R&D efforts, and our success is likely to enable considerable customer innovation across a number of high volume applications in both gallium arsenide and indium phosphide material. In 2021, we delivered pilot quantities of eight-inch gallium arsenide to our customers, generating $hundreds of thousands in revenue. We believe this revenue demonstrates our customer commitment to the next major step in technology advancement. In 2022, we will continue to work to expand our output and refine technical specifications to meet customer requirements. Now, in closing, 2021 was a pivotal year for our business. With substantial revenue growth and a 350% increase in our profitability. If we look ahead, we believe our momentum will continue.
With our current market drivers, we believe we can deliver revenue growth in 2022 of 15%-20% of our 2021 results. This is expected to come from market expansion, share gains, and customer wins. Our investment capacity, R&D for large diameter substrate, and our China IPO give us significant competitive advantages in our ability to scale our business and meet the need of tier one customers and emerging high volume applications. We now have a strong foundation in place and believe that the stage is set for yet another year of meaningful growth in 2022. I will now turn the call back to Gary for our Q1 guidance. Gary?
Thank you, Morris. As Morris discussed, the demand environment remains strong in Q1. Coming off a very strong Q4 in fiscal year 2021, we're expecting revenue to be between $38 million and $40 million in Q1 of this year. In accordance with our commentary on gross margin, we believe that our non-GAAP net profit will be in the range of $0.07-$0.09, and GAAP net profit will be in the range of $0.05-$0.07. Share count will be approximately 42.8 million shares. Okay, this concludes our prepared comments. Morris and I and Leslie will be glad to answer your questions now. Operator?
Thank you. As a reminder, to ask a question, you'll need to press star one 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 Richard Shannon from Craig-Hallum. Your line is now open.
Well, hi, Morris, Gary, and Leslie. Thanks for taking my questions. Maybe a couple of quick ones on the guidance here. Obviously, a very, very nice numbers on the top line. Let me focus on gross margins here first, given the bottom line profit numbers here and EPS. It would suggest that gross margins aren't going to be improving much sequentially, if at all. How would you characterize you know, that and all the dynamics that hurt the gross margins in the second half of last year? Are they improving to a degree? And then any effects of mix in there as well, please?
Well, I'll go first, and Morris can follow up. Actually, we think gross margin will improve quarterly to quarter this year. We think this coming Q1 is probably the bottom. We'll see things improve. I would say that the costs of running the business all the way from raw materials to manufacturing consumables like polishing pads, labor, they have gone up a surprising amount. I think we're playing catch up as to how to handle that. Now that we see the light, we don't think it's gonna get, you know, magically turn back and get better, so we have to take other steps to handle that. I think yield efficiencies can be improved. We're certain that product mix will continue to lean towards indium phosphide.
We're certain about revenue growth, you know, very confident there. All of those combine to help the gross margin percent. As we move through the year, you know, we'll take a look perhaps at whether we should try and raise some ASPs.
Yeah, Richard, let me tell you from my perspective. Yeah. Indeed, you know, raw material plus electricity, you name it, everything has gone up. This one has not happened in the last, what, 15 years or so. It is very strong. Internally, we are already talking about among ourselves. We think it is time for us to ask our customers to work with us and see if we can do some adjustment to bear part of the cost. That is question number one. I think we will be successful in certain areas. We definitely are starting to do that already. The second is that, as Gary said, there are some efficiency improvement, you know, that we need to do to ourselves to lower our costs.
Thirdly, I think, you know, last year, we started to get into some of the lower margin business just to get our foot in the door because we know that there's a shortage in the HBT market, and there's a quite substantial amount of shortage. We took a lower margin business to get in there, but we think as we're getting qualified, we should be able to get not only the volume increase, but also improve our margin, as we go into a more formal delivery to that market.
Okay. Some good stuff to think about there. While I ponder that, let me get to another question here, Morris, on your growth outlook for this year. You reiterated your belief of 15%-20%, and you gave us a number for indium phosphide of 35%-40%. I guess the first part of the question I'd like to ask is, with the health sensing applications, how much of that application is contributing to that growth? Is it a small amount, medium amount? And is this one customer or more than one customer contributing to that this year?
The design win we talked about in our script was one customer, and they start to ramp in the Q4. The revenue is meaningful, but I think it's even more exciting is I think there are two more products to be introduced sometime this year, and we believe one is coming perhaps as early as Q3.
Just to make sure you see this as a meaningful contributor to the growth profile of indium phosphide.
Yes.
this year or a meaningful amount, excuse me.
Yes.
Okay. Excellent. That's helpful. Maybe following back up on the gross margin topic here again, Gary, in your prepared remarks, you talked about, you know, hoping to reach 35%. Do you require, you know, pricing increases to make that a reality, or is that something you can do just with yields and maybe, you know, volumes and other things on the cost side?
I think we probably need some help on the pricing too.
Gary, I think you also mentioned a strategic customer that you're getting some good pricing that hurt gross margins a little bit. Is that specifically referring to the health sensing application, or is this something else?
No, it was a HBT market.
Was the HBT market. Okay. Okay, that's helpful. I guess last one question for me, I will jump out of line here. CapEx, I think you spent $10.5 million last quarter. What's the outlook for this year? When do we get to more of a normal run rate here? We still have heavy amounts of capacity and other investments to make here this year.
Yeah, that's a good question. We, you know, we're trying to soft land some of the CapEx stuff and wind it down, but we really view this as an investment time for the, you know what I mean? The market is red hot, and so we, you know, we need to stay up with it. Normally we would do, you know, $4 million-$6 million in equipment. I think this year it could be between $7 million and $9 million. That's the normal stuff. We'll probably have to do some facility work for indium phosphide, which will be several million dollars, maybe as much as $5 million. Again, we view that as an investment.
The horizon looks very bright, you know, we certainly have got the attention of the customer base because we're the ones that can move the fastest and grow capacity. MicroLED is being studied carefully. We don't know for sure where that's going yet, so if it heats up, then we may do some CapEx in that category as well, but that's to be determined. We, you know, we'll keep you posted. That's the, you know, our sense of that.
Okay.
For that time. Yeah.
Okay, perfect. I think that's all for me. I will jump on the line. Thanks, guys.
Okay.
Thank you. If you have a question, it is star one. Again, if you'd like to ask a question, that is star one. Our next question comes from Hamed Khorsand from BWS Financial. Your line is now open.
Hi. First off, I just wanted to say, you've usually and historically not had so much clarity as far as growth is considered throughout the year. What's giving you that clarity this year?
Yeah, that's a very good question. I'm glad you noticed that. We usually don't have visibility even to the next quarter. Because of the increasing demand and from what we know, quite a few of these product points, and let me give you example for indium phosphide. We are certainly sold out. We have extended our lead time. We normally quote 4-6 weeks, now it's up to the 8-10 weeks. Okay? From our marketing check also, our competitor's lead time is even longer, okay? For the HBT, for gallium arsenide, the lead time is extremely long, and that was the reason why we have exited that market for many years. Now the customers are coming back to us and asking us if we can build some capacity for them.
We're in close, you know, discussion with them and see if we want to get into that market. We do have good visibility. I mean, we also have good visibility in terms of microLED. However, because it's a new market, we're not counting it in until we see it clearly that it's gonna come to fruition. As you can see that we already started to generate revenue from eight-inch gallium arsenide, even that is giving us better visibility of how things will shape up. Yes, you're right, the visibility is better. In fact, I mean, we never thought. In the past years, we can never say, "Well, this year our indium phosphide will grow 35%-40%." We think we have high confidence it will grow that fast.
Okay. What prep actions or process are you taking to prevent, you know, double ordering as far as your customers are concerned?
That's a good question. I think maybe the confidence level from us is this way. You see some of these, let's say the design win we had last Q4 of last year. We worked with this customer almost for two and a half years. We finally got it and, you know, double ordering or whether they're building inventory, that could also happen, but we're not seeing it. We don't see a big jump up on demand. In fact, our indium phosphide capacity as of now is all sold out. That's why our lead time is getting up to 10 weeks. From what we know, our competitor is even longer. I think our competitors are more reluctant, I believe, to build capacity.
To build capacity these days is not an easy thing to do, especially indium phosphide. It's a very difficult process to establish, and we believe that we have an advantage of building the capacity quickly for them.
Okay. My last question was, Gary, what's the adequate level that you think you could preserve cash? I mean, you've continuously burned cash throughout this growth process. When could we see a reversal of that?
Well, I think it's directly linked to CapEx. I don't have a CapEx plan for 2023, but I'm hoping that, you know, we'll see it slope down. I would say that I'm comfortable with our cash position. You know, inventory took a big jump up during last year, so I don't see that, you know, having to go up a lot more. You know, we're still looking again until the IPO happens, we're looking at some bank borrowing in China. You know, it's interesting note, once our IPO application was accepted, which was on January 10, there's surprisingly a lot more interest from the banks for Tongmei to secure debt.
It's having a, maybe Morris can comment also, but there's a ripple effect of different organizations and, you know, China-based institutions that are excited about Tongmei, are excited about the IPO. Yeah, I'm not losing sleep over cash, but we do watch it carefully and, you know, I know it went down in the Q to Q, but I think we're okay.
Well, I would add on to this. I mean, look, 44% growth takes a lot more equipment, facilities and inventory, accounts receivable. I mean, I'm not a financial expert, but I know all that requires cash. I think we are generating good cash flow, Gary. I mean, we did a cash flow analysis. We think we can handle it. I think, you know, going forward, you know, if you think some investor probably wants to see the cash flow slow down, I think otherwise. I think when we have cash flow outward strongly, that means our business is growing. We need the cash to grow our business.
You know, since when we can get very close to $40 million a quarter, and my goal is sometime this year, we're gonna break $50 million a quarter. That's unthinkable just a year or two ago. That all needs, you know, better organization, better foundation, which we're building. That all needs cash. Great. Thank you.
Thanks, Hamed.
Thank you. I am showing no further questions. I would now like to turn the call back over to Dr. Morris Young for closing remarks.
Thank you for participating in our conference call. As always, feel free to contact me, Gary Fischer or Leslie Green directly if you would like to set up a call. I would looking forward to speak with you in the near future.
Thanks, everybody.
Thank you. This concludes today's conference call. Thank you for participating. You may now disconnect.
