Thank you, Yonah. Good morning, everyone, and thank you for joining us. Stratasys had a strong quarter with over 17% revenue growth compared to the same period last year, driven by the highest system sales since Q4 of 2018. Each of our technologies and all of our regions contributed to this growth. I will share a general overview of our achievements and milestones in 2021, and after our financials and guidance, I will conclude with some thoughts for 2022. Stratasys today is in a very different place than it was at the beginning of 2021. Until last year, our business had been centered around two core technologies, FDM and PolyJet. While we maintained leadership in these areas, this limited portfolio meant we were missing opportunities to participate more fully in the fast-growing applications at the heart of the shift from prototyping to manufacturing.
We had not developed and launched meaningful product upgrades in a number of years. It was critical to evaluate the entire business and target strategic investment to evolve our product portfolio. We established our strategy to be the first choice in polymer 3D printing, encompassing the entire product life cycle with multiple technologies and complete solution for superior application fits across design, manufacturing, and healthcare. We believe this approach provides the largest total addressable market in the industry. This strategic focus drove us to specifically increase our exposure to manufacturing applications. A year ago, we shared that in 2020, over 25% of our revenues came from manufacturing. We are pleased to say that for 2021 it was 29%, and we expect 2022 manufacturing sales to grow at least 20%. Clearly, our focus on manufacturing is working.
We accomplished this with new systems tailored to manufacturing at scale, a software platform to integrate the entire manufacturing digital thread, and a material strategy that rapidly opens up new applications for our customers. Today, we are collaborating with the world's leading materials companies, software partners, and our customers, creating many new avenues for growth through a combination of direct sales and licensing. We are excited about this broader portfolio and believe it will further complement our systems offering to help drive our overall growth strategy. There is more to come in the years ahead. We also dramatically strengthened our balance sheet in 2021. At year-end, we had over $500 million in cash and equivalents, up from $272 million as of the end of 2020, giving us flexibility to seek opportunities that will support our future growth.
We believe that by continuing to prudently invest capital back into the business, we will achieve meaningfully accelerated revenue earnings and cash flow in the years ahead. Now, let me provide more specific color on our 2021 accomplishments that were supported by our strong balance sheet. The first area of focus was strategic acquisitions, including Origin, which was completed at the very end of 2020, RPS, and Xaar 3D, which will support our customers' manufacturing needs and begin notably contributing to our growth in 2022. Next, we expanded our software capabilities and plan to add licensing to give customers access to our new open materials options. Additionally, we initiated a long-term technology investment arm that has already deployed capital in companies with cutting-edge technologies such as material jetting, post-processing, and continuous carbon fiber.
Building on our five industry-leading 3D printing technology, we introduced several new product offerings over the course of the year, including three systems targeting our manufacturing customers. First, the Origin One, designed for end-use manufacturing applications that uses P3 technology to produce parts at volume from a wide range of third-party photopolymer materials. After a very successful beta program, we just recently started shipping this system. Next, the H350, the first of our new H Series powder bed systems, powered by SAF technology and built to deliver production-level throughput of end-use parts which we started shipping in December. The F770, an FDM printer ideal for large parts, featuring the longest fully heated build chamber on the market. We also introduced 3D printers tailored to some of our most important industry application segments.
This includes the Origin One Dental printer and the J5 DentaJet. Together, they provide dental labs with comprehensive additive manufacturing solutions for the large and growing dental market. We also launched the J5 MediJet printer, which gives healthcare customers the ability to print highly detailed anatomical models and drilling and cutting guides quickly and cost-effectively with approved third-party 510(k)-cleared segmentation software. We introduced the J35 Pro and J55 Prime PolyJet printers, along with new software solutions for research and packaging prototyping. Finally, after acquiring RPS in Q1 last year, we launched the Neo line of industrial stereolithography systems, expanding our offerings to use cases such as investment casting patterns, orthodontic clear aligners molds, and large design parts. In addition to the new systems, we made significant progress on increasing our software focus and offerings.
We introduced an enterprise-ready open software platform tailor-made for manufacturing. This is important because it gives our customers the ability to integrate fleets of Stratasys printers with their existing Industry 4.0 infrastructure and workflow, allowing them to really scale their use of additive manufacturing. It also strengthens our relationship with our customers because we can use software to continue to add value to their investments in 3D printers. That in turn means recurring software revenues can become a growing contributor to our business. For example, we announced that we have extended GrabCAD Print software to our H350 printer. For an annual licensing fee, this enabled enhanced functionality focused on optimizing production throughput that is specifically designed for end-use parts manufacturing at scale.
We also continue to invest in additive specific applications to streamline the workflow of orders through the factory shop. On the material side, we introduced CF-10, our new carbon fiber material that we believe will increase the adoption of our technology into production lines, especially for manufacturing aids. CF-10 has also proven to be a catalyst for increased sales of our F370 system. We introduced open materials option for FDM that we plan to launch in the back half of this year, starting with our Fortus 450. We expect this to spur materials innovation, accelerate the adoption and expansion of our consumables, and contribute to increasing our software revenues. We also entered into a number of important partnerships, including ECCO, Adobe, Red Hat, and others, as we seek to provide our customers with complete end-to-end solutions for specific industry applications.
These accomplishments in 2021 were thanks to the hard work of our exceptional team at Stratasys. Together, while managing through the many pandemic and related challenges, we successfully launched over 30 new products into the market. I am very proud of our team and excited to experience even more this year. As we execute on our strategy and build momentum, customers continue to express their confidence in Stratasys. For example, ECCO, a leading global shoe manufacturer, is using our Origin One to print molds and shoe lasts for development purposes. Not only do these parts fully match the quality requirements of their CNC machined aluminum counterparts, but they are faster to produce and far more economical. Another example is Radford Motor Company, one of the two automotive OEM that are already utilizing all five of our technologies.
For each of their coachbuilt supercars, Radford prints hundreds of Stratasys parts, from design through prototyping, tooling, and end-use parts that can be found on the final vehicle. We believe this level of 3D printing technology adoption will become standard in the automotive industry. I would like to take a moment to discuss our effort and accomplishments with regard to ESG. This is an area of primary focus for our company and our industry. 3D printing has the ability today to address many of the environmental issues facing global manufacturing, and we are at the forefront of those efforts. At Stratasys, we are deeply embedding our ESG strategy in our products and processes. As part of our DNA and company purpose to empower people to create without limits for an economical, personalized, and sustainable world, we are addressing many of our business processes.
Along with our customers, we seek to take climate action while improving social impact. We call it mindful manufacturing, a call to action to redesign processes, parts, and supply chains with great thought and clear intentions to secure manufacturing, utilizing 3D printing in a way that maximizes sustainability while also supporting business growth. By digitizing, localizing, and optimizing for additive manufacturing, we believe net zero targets are not only achievable, but easier to reach than with traditional manufacturing technologies and processes. Our efforts encompass product innovation and improved circular economies for additive manufacturing, and extensive outreach in our communities through education and healthcare CSR activities around the world. We plan to publish a first of its kind, market-leading, pure polymer additive manufacturing GRI sustainability report next quarter.
As the market leader in 3D printing, we see our role as leading the shift to responsible consumption and production, helping our customers achieve their carbon neutrality, net zero goals, and working to address our own footprints, supported by the data and research needed to drive this transformation for the entire additive manufacturing industry. Before I turn the call over to our new CFO, Eitan Zamir, to share the financial results, I wish to thank Lilach Payorski for her leadership and many significant contributions to Stratasys over the past nine years. Lilach built a strong, talented finance organization, and her dedication to excellence and professional expertise has helped to preserve and strengthen our financial health as we navigated dynamic markets and pursued strategic growth initiatives. We wish her the best in her future endeavors. Eitan?
Thank you, Yoav, and good morning, everyone. Before I begin my remarks, I would also like to personally thank Lilach for her guidance in the over 2 years I've been with Stratasys. Her contribution and commitment to the company have been a fundamental part of our success, and I am honored to be assuming the role as CFO at this time in our journey. Now turning to the numbers. The fourth quarter of 2021 was another period of successful execution for our company. We delivered the highest quarterly total revenue and highest quarterly system revenue in 3 years. Cash generated from operating activities was positive for the sixth consecutive quarter.
For the fourth quarter, total revenue was $167 million, a 17.3% increase from the prior year quarter, driven primarily by strength in system sales, which was the highest in twelve quarters and is typically a driver for future consumable sales. Total revenue was up 5% sequentially from the third quarter and was 4.3% higher as compared to pre-pandemic Q4 2019 levels. On a constant currency basis, total revenue increased 18.3% year-over-year. Product revenue in the fourth quarter was $118 million, an increase of 19% compared to the same period last year, or 20.1% on a constant currency basis.
Within product revenue, system revenue increased 25.9% to $61.8 million compared to the same period last year, and increased by 26.9% on a constant currency basis. Consumables revenue increased by 12.3% to $56.3 million compared to the same period last year, and increased by 13.6% on a constant currency basis. Service revenue was $49 million, an increase of 13.3% compared to the same period last year. On a constant currency basis, service revenue increased by 14%. Within service revenue, customer support revenue increased by 7% compared to the same period last year, and increased by 8.1% on a constant currency basis.
We were pleased to see a strong and growing contribution from healthcare and dental, and also to see consumable and customer service revenue above 2019 levels. Now turning to gross margins. GAAP gross margin was 43.7% for the quarter, compared to 46.4% for the same period last year. non-GAAP gross margin was 48.7% for the quarter, compared to 49.5% for the same period last year. The decrease in gross margin versus the prior year period was driven mainly by raw material inflation and ongoing logistical challenges, partially offset by the impact of higher sales and sales mix. GAAP operating expenses were $89.2 million, an increase of $20.7 million or 30.1% from the same period last year.
non-GAAP operating expenses were $79.6 million, an increase of $17.4 million or 28% compared to the same period last year. non-GAAP operating expenses were 47.7% of revenue for the quarter, compared to 43.7% for the same period last year. The increase in operating expenses was driven by a number of factors, including the return to a five-day workweek, higher expenses as the market recovered, higher operating costs and commissions due to more revenue and additional operating costs associated with the inclusion of our new acquisitions, including full ownership of Xaar 3D in the fourth quarter. These costs were funded by the resizing plan implemented in May 2020, which allowed us to allocate resources to areas where we believe we will generate stronger growth.
Regarding earnings, GAAP operating loss for the quarter was $16.2 million, compared to a loss of $2.5 million for the same period last year. Non-GAAP operating income for the quarter was $1.7 million, compared to $8.3 million for the same period last year. The difference reflects the increase in operating expenses in the fourth quarter of 2021 described before, including due to our move from a four-day workweek to a five-day workweek. GAAP net loss for the quarter was $4.8 million or $0.07 per diluted share, compared to net income of $11 million or $0.20 per diluted share for the same period last year, which reflected a one-time $14 million tax benefit in the fourth quarter of 2020.
Non-GAAP net income for the quarter was $ half a million or $0.01 per diluted share. Compared to $7 million or $0.13 per diluted share in the same period last year, reflecting the increased operating expenses in Q4 2021 compared to Q4 2020. Adjusted EBITDA of $7.9 million compared to $14.6 million in the same period last year, reflecting the increased operating expenses in Q4 2021. We generated $4.4 million of cash from operations during the fourth quarter, compared to generating $23.7 million of cash in the same quarter last year. This was our sixth consecutive quarter of positive cash flow from operating activities. It was driven by strong collections and achieved despite of an increase in inventory purchases.
We ended the quarter with $502.2 million in cash equivalents, and short-term deposits, compared to $299.1 million at the end of the fourth quarter of 2020. Our cash position was bolstered by a $230 million capital raise in Q1 of 2021. We have executed with excellence to overcome the negative impacts of the pandemic and remain well-funded and well-positioned to capitalize on value-enhancing market opportunities as they arise. Now, let me turn to our initial outlook for 2022. We're guiding that our 2022 revenue will be in a range of $680 million-$695 million. We expect to realize sequential revenue growth each quarter as we progress throughout the year, with the second half of the year notably stronger than the first half.
The sequential growth is somewhat different than our historical seasonality pattern, primarily due to the timing of new system releases and the corresponding ramp in sales, as well as gradual shifts in sales mix. Q1 revenue growth is expected to reach high teens% over the first quarter of 2021. From a gross margin perspective, given our experience with the global logistics and material cost issues, full year 2022 is expected to be flat to slightly higher than 2021, with the second half stronger than the first half, based primarily on higher revenue. We expect the first quarter to be relatively flat to the first quarter of last year. I would like to emphasize that we view the current gross margin situation as temporary.
As the headwinds caused by these external issues pass and we continue to execute on our long-term plan, we expect our margins to head back over 50%. We will continue to invest in our growth engines to generate significant leverage benefits as we responsibly build a strong company for the long term. In 2022, we expect our operating expenses to be approximately $20 million-$25 million higher than 2021, primarily due to the impact of owning Xaar 3D for the full year, higher costs that result from higher sales, and investment in new growth drivers such as Origin and healthcare. I would like to remind you that starting from the second quarter, operating expense is typically higher than the first quarter due to the normal timing of compensation expenses.
Despite the higher absolute dollar value year-over-year, we expect to see a continuation of reduction in operating expenses as a percentage of revenue throughout the year. Improving profitability objective for us. For 2022, we expect to see continued improvements in our earnings. We expect non-GAAP operating margins to be slightly above 2% for the full year, with small operating losses during the first half, and turning to profit in the back half of the year due to the anticipated revenue increase. Longer term, we expect operating margin to achieve double digits as our growth plan unfolds in the coming years. We anticipate a GAAP net loss of $74 million-$67 million, or $1.11-$1.00 per diluted share, and non-GAAP net income of $10 million-$13 million or $0.14-$0.19 per diluted share.
Adjusted EBITDA is expected to be in a range of $38 million-$41 million. We expect our capital expenditures for 2022 to range between $20 million and $25 million. With that, let me turn the call back over to Yoav for closing remarks. Yoav?
Thank you, Eitan. 2021 was a transformative year for Stratasys in many ways. We vastly improved our offerings, strengthened the balance sheet, and invested in technology, positioning us for continued growth in the years to come. We experienced our largest contract in company history with a $20 million order from U.S. Navy for 25 F900 manufacturing systems. Importantly, this is more than just a one-time sale. We are fully qualified and selected as an additive production partner, opening the manufacturing door for us, and we expect to scale adoption quickly. We had another large long-term F900 sale as well to a leading global OEM. This and other manufacturing related deals demonstrate market confidence in the use of Stratasys technologies as the market shift from rapid prototyping to true manufacturing. A clear signal, the 3D printing industry has reached this important inflection point.
In 2022, we will advance our efforts to strengthen our leadership in polymer 3D printing. We have established the foundations for long-term growth based on leading polymer 3D printing systems, complemented by continuous innovation across our portfolio. Two key components of this effort include the H350 and Origin One. Both products have been well received in their beta programs, and we believe this system will help to more than double our addressable market over time. Equipped with best-in-class offerings, unmatched go-to-market network and support infrastructure, a strong balance sheet and the best 3D printing talent relentlessly focused on execution, we are positioned for sustained growth and strong stakeholder returns as we further build on our momentum in 2022. Looking ahead, we are energized and excited for the future of Stratasys. With that, let's open it up for questions. Operator?
Thank you. At this time, we will be conducting a question and answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. As a reminder, we ask that you limit to one question and one follow-up. One moment please, while we poll for questions. Our first question is from Greg Palm with Craig-Hallum Capital Group. Please go ahead.
Yeah, thanks. Congrats on the continued progress here. Eitan, congrats on your transition to CFO. Look forward to working with you more closely going forward.
Thank you, Greg.
I wanted to just start off on new product contribution. T he question lies more upon the feedback and traction out in the marketplace and what you're seeing and hearing from both your installed base and new customers. Again, this is specific to the new products.
Hi, Greg. Good to talk with you. Great question. We are fully geared to leverage the new product in the market. Just think about thousands of customers that we have out there and hundreds of partners that just need to sell one or two or three more technologies to the same customer. We have fantastic new products in the market. I know I can go briefly, start with the SAF, great pipeline, solid pipeline and really unmatched quality of parts. I'm amazed every time that I see the flexibility of this machine and the ability really to compete with injection molding. I'll go to the Origin. We just finalized the beta and moved to general availability. No, we are not sharing grades, but we had great remarks and grades from our customers, both industrial customers and dental customers.
The main advantages of this machine, this is a unique, patented, layer separation, really a complete different way of running DLP systems. The result is an unmatched part quality, speed and reliability. We really look forward to provide to you and to the public more information throughout the year on the performance of those two machines. We also introduced the RPS, great results above our expectations. The J5 DentaJet on the PolyJet side, when you combine it with the Origin One Dental, it's an amazing, great portfolio, new portfolio that we have that is very attractive to the dental industry. When you combine all of it together, practically we have new product in each one of our technologies. I start with the PolyJet, the J35 Pro, the J5 MediJet, the J5 DentaJet. I move to FDM.
We have the F770, which is the largest build chamber, the longest build chamber in the industry. Really great traction in the market. I move to the SAF, and the Origin, and the RPS. We are really geared to grow based on the new product.
That's helpful. Yoav, when you joined, you talked a lot about Stratasys being kind of a one-stop shop for customers looking to invest in additive. Now that you have the product portfolio sort of set, are you seeing any tangible evidence of this happening? I don't know whether that's market share gains, maybe that's just increasing sort of wallet share spend within existing customers or maybe just new growth with new customers. What's your thought on how that strategy is playing out?
The short answer is yes, but let me elaborate on it. We already have two automotive players, OEMs, using the all five technologies, which is amazing. Why it's so important? Because manufacturers, bottom line, when you look at manufacturer, they prefer to have one provider with one ecosystem, with one production environment, with someone they can count on. This is exactly what we are bringing to the market. We are not selling technology. We are selling the best solution that fits your problem. We are coming to solve problems to our customers. This is a completely different position in the market compared where we were two years ago, and it works. Of course, this is just the beginning, but we are very encouraging from what we are seeing in the market and from the discussion I have with customers on a weekly basis.
Okay, perfect. I'll head back in the queue. Thanks, and good luck.
Thank you. Our next question is from Troy Jensen with Lake Street Capital. Please go ahead.
Hey, gentlemen. Congrats on the good quarter and the good year. I guess-
Thank you.
M y first question, I wanna talk. You're very welcome. Can you just talk about Q1 guide seems it's much better than normal seasonality, and you feel it in the balance, your deferred revs were up slightly quarter-over-quarter. I'm just wondering, was there any constraints in Q4 that held back any sales and are they flowing into Q1 or is the better than normal seasonality really just the H350 starting to launch?
Hi, Troy. Good morning. A good question. There were no constraints in Q4. The increase is driven by our new products as well as our other technologies, our old technologies, and we started the year with a strong backlog.
Okay, perfect. Could you just confirm you did have H350 revenues in Q4, and then are you expecting to ship the Origin for revenues in Q1 also?
Yes. In Q4, we already had the SAF product, and in Q1, we started shipping Origin, and we'll have revenue from Origin in Q1.
Awesome. All right, guys. Congrats. Good luck this year, and I'll follow up on my call later.
Thank you.
Thank you. Our next question is from Jared Maymon with Berenberg. Please go ahead.
Hey, good morning, guys, and congrats on the strong results. First question for me. I'm just wondering, with the Origin One Dental, do you have some big customers trialing that yet? H ow likely do you think the opportunity is there to take share with that product?
Thank you for the question. Of course, we ran a total beta program with some large and some medium and also some small customers to make sure that we are covering the whole range. We got fantastic feedback from the beta. We are very encouraging. It's really a unique value proposition in industrial dental in terms of the quality of the part, the accuracy and the speed, and this is only the beginning. We can do many different applications with one platform. You can go to the Origin in dental, in tooling, in models, aligners, dentures, splints, guards, stamps, bridges.
When you combine it also with our PolyJet, we are covering the whole range, and this is a really great value proposition to medium and large dental customers that we are targeting.
Yeah. Jared, it's Yonah. I would just add on top of that quickly that as strong as the aligner market has shown to be a good adopter of this technology over time, we see dentures as an even larger market opportunity. The Origin system we discussed when we first announced it a little over a year ago, that was gonna be one of the target markets. We really look forward to updating the market around that particular end use at the appropriate time.
Great. Perfect. Good to hear. Then I'm just curious. You mentioned briefly you have a team that's deploying some capital in various opportunities, and one of those you called out was continuous fiber. Is there any color you can provide on this?
Yeah, we received this question so many times, so it's good, too, that you raised it. We have a very strong balance sheet, so we have to use it in the best way that will generate returns to our stakeholders. We believe that the best way to do it is to focus on our strategy. We have a laser-sharp strategy on polymer manufacturing. We are doing really well on the growth side and creating the most sustainable, strongest company in the industry, and this is very attractive to many startups. We are being approached by many startup, and we decided to establish an investment arm we call it, Stratasys Ventures. It's all about accelerating the implementation of our strategy.
We know exactly where the gaps that we have, mainly in the workflow, and exactly where are the needs and the gaps in the industry, and we are bringing the go-to market. We are investing in very exciting technologies, like we said in the script, like continuous carbon fiber. We just recently invested in 9T Labs that have a very unique way of having X, Y, and Z continuous carbon fiber, not only X, Y. They just closed $17 million round, and we were there. Other companies that we cannot elaborate now, but it's a very strong pipeline of external innovation that will help together with our great people in R&D to make sure that we are keeping our technological leadership in this market.
Because our machines are the most reliable, the most repeatable in the market with the highest throughput, and this is what manufacturer looks for out there. We can deliver it internally and externally, and we have a very clear framework how to do it.
Got it. Thank you.
Thank you. Our next question is from Jim Ricchiuti with Needham & Company. Please go ahead.
Hi. Thank you. The question I had is just with respect to the comment that I believe you made regarding the gross margin pressures being temporary, and I'd like to follow up on that and maybe drill down a little bit more. Are you anticipating just the mix of revenues benefiting your gross margins, the scale-up in volume? Or are you taking some other measures to offset some of the pressures that you're facing? Because it doesn't sound like some of these cost issues are necessarily going away.
Hi, Jim.
Hi.
Good morning. It's a good question.
Morning.
First one part is the anticipated improvement in logistics and raw materials in the future. We also proactively, as we scale up our business, as the new products become more mature, to optimize and to improve our margins in our processes.
Okay. Just with respect to your outlook for 2022 on the revenue side, maybe you could talk a little bit about which of the verticals do you see the biggest growth potential. Y ou're clearly, it sounds like you're excited about what you're seeing in the dental market, but I wonder if you could just give us a little bit more color in terms of how you're thinking about the year from the standpoint of vertical markets.
Thank you for the question. We, by definition, when we launched our new strategy going for manufacturing or what we call end use parts, we decided that we are going to focus on a much larger market to increase the total addressable market, both because of the new technologies, but not less important because of new verticals and new applications. Of course, we have our verticals like the government and the defense and aero and auto, and we're doing really well there. Within that, we want to shift from prototyping to manufacturing. We are the first company in this industry to say 25% of what we are selling is going to end use parts. It was 2020. In 2021, we are already in 29%.
We believe that it will keep growing, but this year will keep growing above 20% every year. The strategy works. Where we focus, manufacturing and healthcare. Manufacturing across many verticals, from consumer goods to aero and auto. When you go from manufacturing to healthcare, it's mainly dental, but also not less important is the whole PST, what we call pre-surgical planning, where we are sitting on the best technology in the industry. We are the only one who can deliver real imitation of anatomic models where you can really imitate the tissue. We just launched this year what we called Digital Anatomy Creator, where the surgeon or the radiologist can really imitate the tissue and customize it to the different patient.
We believe it will position us as the leader when insurance and reimbursement will occur in this area because it is saving lives. Bottom line, manufacturing and healthcare.
Thank you.
Thank you. Our next question is from Ashley Ellis with Cross Research. Please go ahead.
Hi. Thank you for taking my question. Eitan, I was wondering if we could dig a little bit deeper into the revenue guidance. You're obviously going against some pretty tough comparison in system revenue, and I know you're launching the Origin and SAF should ramp up. How should we think about system growth versus your recurring revenues, your consumables and customer support? Should we expect that there should be some sort of follow-on from the strong system sales in 2021? I have a follow-up. Thank you.
Thank you, Ashley. It's a good question. We're very excited about 2022, and we expect all our streams to grow. Hardware will be the driver for the increase, but consumables and services will follow.
Are you factoring any software contribution into the revenue guidance?
Ashley, it's Yonah. Hey. Software is not gonna yet be meaningful. It's sort of just starting to launch through. As we mentioned earlier, there'll be some software licensing revenue we're gonna start to get as we do the open materials, which is beginning in the back half of the year on the F 450. But we'll be sure to update you as software becomes a more meaningful part of the revenue.
Yeah. If I may, add, we are going to launch new software products in 2022.
Okay. Yoav, could you talk about the decision to open up the FDM printers to third-party materials, like why now? Is there the potential you could open up your PolyJet systems in the future?
I would say it's an act of leadership. We are leading this industry from prototyping to manufacturing. We had a very thorough analysis and many discussions with manufacturers out there, and we identified the barriers. One of the barrier is the variety of materials they can use for real manufacturing applications. It's clear to us that it's better to be in manufacturing and sell thousands of ton instead of few kilos per machine, and to have a much better unit economics and to support our customers. Bottom line is delivering higher value to our customers. The open material, it's all about innovation and partnering around innovation because it's not that we open it without any responsibility on the quality of the part.
This is a hybrid model, a controlled open material model where we are working together with our customers in three tiers. We have tier one, which is preferred. We already announced it. It's exclusive for Stratasys. The second one is certified. We are certifying other suppliers, third-party suppliers, but it meets our standards. We have exploratory, where everyone can innovate and do better things. It's FDM. We are focused. All this new innovative model is focusing on manufacturing. It's FDM, it's SAF, and it's Origin. We get great feedback from our customers, which will allow us not to introduce one or two or three new materials a year, and you will see it because it's in the roadmap, to double or triple the amount of new materials that we are introducing.
We see it also in RPS, for example. It's open, it's doing really well, and it give us a competitive edge and a lot of value to our customers and to us. Bottom line, when we are talking about opening the material, it's not about having now a model that is where we are losing responsibility or compromising on the quality. It's exactly the opposite. It's about giving more value to our customers in a responsible way and making sure that we are creating the value and the cake to everyone. As for PolyJet, no current plans to open it up because it's prototyping, and it's a completely different type of need, and we have most of the material needed for prototyping. It's focusing on manufacturing, doing it with our customers.
They love it, and also they appreciate the leadership here.
All right. Thank you very much.
Thank you. Our next question is from Paul Chung with JP Morgan. Please go ahead.
Hi. Thanks for taking my question. Can you talk about the interesting things you're doing in aerospace? Can you expand on the Boom partnership the U.S. Navy contracts and how you see those relationships evolving? Maybe kind of potentially leading to interest from other customers and how material can this part of the business contribute to growth? I have a follow-up.
Thank you, Paul, for this question. I think it's a reflection of how we are partnering with our customers to change the world, not less than that. I'll take the Navy, for example. This is the ultimate example of distributed manufacturing. People are talking about it for years, for decades, about distributed manufacturing. We are working with the government, we are working with the Navy to really implement distributed manufacturing. There are supply chain issues, long supply chains. We are going to have F900 machines within the U.S., outside of the U.S., globally to print spare parts. That's amazing, and I want to thank the Navy and the U.S. government for taking it, you know, together with us, taking all the industry a step forward. It's a real manufacturing opportunity across all government bodies.
If I take it to Boom, it's a great example of innovation in action. We started with them only with prototyping, just to, you know, cut their development cycle and to save significant time. I believe we saved between 2 to 3 years and even more because this ability of the engineer to think about it, about something and then printing the same day to check it is remarkable. They took it to fixtures and features and tooling and then to end use parts. I visited there, and it's like you see parts within the most exciting new generation of passenger aircraft, and it is 3D printed. It's amazing. I learned a lot from both those customers, and this is part of the DNA of Stratasys.
We work with our customers to make sure that they will be more successful and that 3D printing will be significant in manufacturing. We have many more of this.
Great. Thanks for that cool stuff. Just on cash flow you managed inventory levels really well and seeing some funding benefits from kind of longer accounts payable days. If you could expand on how you managed the inventory levels so effectively this year, and then how do we think about kind of working cap dynamics in 2022? Then can you grow cash from operating in 2022, keep the streak of kind of positive quarterly operating cash kind of ongoing? Thank you.
Thank you. It's a good question. We're not guiding on cash flow. On one hand, we continue to increase and to purchase inventory to be prepared for the growth during 2022. We do have over $500 million of cash to invest. We're very positive about 2022 as far as it's concerned with cash flow, but we do not guide on cash flow.
Great. Thank you.
Thank you. Our next question is from Wamsi Mohan with Bank of America. Please go ahead.
Yes, thank you. I just wanted to follow up on the cash flow question. If you look at your midpoint of your operating income guidance, it's about $18 million improvement on a year-over-year basis, which is great to see in 2022. Maybe if you don't wanna give an explicit cash flow guide, can you talk about some of the underlying puts and takes that might influence how that increase or decrease in cash flow might trend relative to that increase in operating income? I have a follow-up.
Thank you, Wamsi, first of all. Without guiding on cash flow, when you think about cash flow as compared to operating income, you take into account all the working capital elements. As I mentioned earlier, we continue to invest and try to increase our inventory, and we'll continue doing this during 2022, and this should also be taken into account when you model cash flow for 2022.
Okay. Thank you for that. Then if I think about the excitement that you're really showing around your new products and some of the potential contribution from that, especially in the back half of the year, is there any way for you to talk about in your revenue guide of, call it mid-teens for the year or somewhere close to that, growth? How many points of growth do you think these new products can contribute in year one, year two? Like, I'm sure you have a plan that sort of thinks about contribution sort of on a more ongoing basis. Can you maybe help us think through how we should be thinking about revenue growth on a more sustainable basis and particularly contribution from these new products?
Y ou essentially said, like, you're going from two platforms to this multi-platform approach, and that's really resonating with your clients. If 2022 is maybe some sort of transition year or launch year in some ways, we should start to see some more acceleration from that. Just trying to parse through how many points of growth maybe you can see stacking up over the next few years. Any color there would be helpful. Thank you.
Right. Thank you for the question. We do not provide guidance on a specific products. However, I can say that in 2022 we expect all of our technologies to increase compared to 2021. Naturally the launches of SAF and Origin will have a significant impact in 2022 compared to 2021, b ut we do expect that all our products and all our technologies will generate growth in the future and after 2022.
Okay, thank you so much. Good luck.
Thank you. Our next question is from Ananda Baruah with Loop Capital. Please go ahead.
Hey. Yeah, thanks guys. Congrats on the ongoing momentum, and really appreciate you guys taking the question. J ust two quick ones if I could. Going back to Paul's question, you guys provided some really good context on the Navy relationship as to what's driving sort of driving business with them. Could you provide us some context in a general sense of what customers are doing that's leading to the increased momentum, the ongoing momentum, and just in a tangible way for us? I have a really quick follow-up. Thanks.
Hi, Ananda. Thank you very much for the question. It's a great time to be part of the additive manufacturing industry. I didn't plan it, but I'm lucky. Because customers understand the global trends, and they understand also that additive will be part of the manufacturing of the future. Everybody is planning now their future in manufacturing, the plant of the future, the microplant of the future, customization, Industry 4.0, et cetera, et cetera, et cetera. The pandemic with all the supply chain issues that we are facing as well created the ultimate storm for us to start engaging with our customers. You take together the most fundamental trends that we are experiencing now.
The supply chain needs, the customization, especially in healthcare, the need for sustainability and lighter parts in order to use less fuel, and the innovation in so many areas, like in electric vehicles, and the need for new geometry for this. Additive is the best solution. The U.S. Navy deal proved it. Manufacturers can distribute the digital inventory worldwide. You don't need physical inventory, you can have digital inventory. You can provide parts wherever they are needed. People understand it. The moment they understand it, they are looking for a partner they can interact with in order to develop those plans of the future.
W e are positioned quite well because we are a one-stop shop with one operating system, with one material platform, with one software platform, and with a lot of reputation, reliability and repeatability, and the ability to deliver. It's a very exciting time for us.
That's super helpful. I appreciate the context. My quick follow-up is just on the operating margin guide for 2022. I believe you said about 2%. Can you just describe for us what are the puts and the takes, you know? W hat I'm wondering is, what are the things that allow you to begin to expand those operating margins as I'm assuming as we go kind of through 2023?
Thank you. When we think about 2022 and the over 2% margin we have the significant growth in our revenue. When we think about OpEx, it will decrease as a percentage of revenue during 2022. However, we continue to invest in our growth drivers, Origin, SAF and healthcare. Operating margins can expand longer term due to a number of factors, including the increase in consumables, adding software that is coming with higher margins, and the entire revenue increase that we expect.
The scale. Yeah. Got it.
If I may add, that's exactly the right direction, but it's a combination of external and internal forces. Externally, we do believe that the current logistics cost is not sustainable. We believe that at the second half of the year, maybe next year, at the end of this year, we see better results because of the capacity in sea, because of the port issue. It will solve itself. This ongoing fuel crisis itself will somewhat solve itself as well, s o this is on the external side, b ut we don't base our projection only on external forces. We base our projections on activities, on what we are doing, on being proactive. We believe that selling more hardware means that we sell more consumables.
Selling more consumables, better gross margins. We are investing in higher efficiencies across the company. We are lowering the production costs. What we can do internally, we take control over our destiny, and we design for cost, and we add software, and we have NPI, so we are working on it. We're not coming here and saying gross margin will be better. We are working on it, and it will be better.
That's really helpful. Thank you guys so much.
Thank you. Our next question is from Noelle Dilts with Stifel. Please go ahead.
Hi, guys, and thank you for taking my question. First, I was hoping you could comment on if you're seeing any notable differences in demand from a geographic perspective, if you know what you're seeing in Europe versus the U.S. and Asia. Thanks.
Great question. We are not in general giving the details, but I can give you the high level trend. It's kind of a combination of recovery and innovation, I would say. We see that EMEA, which was lagging compared to the U.S. in adoption of new technologies in many verticals like aero and auto, are catching up. We see very nice results from our EMEA region. We see also great results from the U.S. and then Asia. This is more or less the ranking, but I believe it's only a matter of the pandemic and the recovery from the pandemic. Asia, they adopted a more strict, I would say, Omicron policy.
We see, which is not in Europe and not the case in the US, but bottom line, across the geographies, we see really good demand and the growth across regions is positive and looks really good.
Okay, great. Thank you. Second, I was hoping you could just expand a little bit on what your acquisition pipeline looks like, as you look out over the next year or two, any details on are you seeing more smaller deals or larger deals and what's your appetite for M&As as you look at 2022?
We have a very structured framework for business development activities, starting from acquisition. The bottom line, if I start with the bottom line this time, is about accelerating our strategy, the implementation of our strategy. We don't do anything which is not within the strategy, but within the strategy, there are so many opportunities. We started with acquisitions of base technologies, and now we are moving, I would say, to the next phase, which is about really strengthening those technologies, but investing a lot in workflow and materials. We are moving down the road. We have the base technology. Now we need to make sure that they have the full solution, which is the best. This is materials, this is workflow software, and also a lot of collaboration. It is a combination of investment and collaboration.
Bottom line, we increased dramatically the size of our investment team, and we believe that the combination of external and internal innovation will put us completely in a different way and will secure our technological leadership.
Thanks so much.
Thank you. Our next question is from Brian Drab with William Blair. Please go ahead.
Hi. Good morning. This is Blake Keating on for Brian.
Morning, Blake.
Brian ended up being double-booked, but wanted to get clarity on a couple items, w hat is different about 2022 in terms of your revenue visibility compared with 2019? Because in 2019 you initially guided between $670 million and $700 million in revenue and reported $636 million in the end. What's driving the confidence this year?
Hi, Blake. Good question. We feel very confident about our ability to meet the 2022 numbers. We started with a strong backlog of the year and with the new products and also the existing technologies, we feel confident in being able to meet the guidance.
Got it. Thank you. Then, how should we reconcile the below-the-line EBIT guidance? You know, it implies about $14 million-$15 million in EBIT with the adjusted EPS guidance. Is it tax rate, or how should we think about it?
Sorry, Blake, could you say that again? We didn't hear the last part of your question.
Yeah. How should we reconcile the difference, the EBIT guidance of about $14 million-$15 million to the net income guidance, the adjusted EPS guidance? Is it tax rate or what's the, how should we get down to it?
Right. Like it's a good question. There is nothing between the EBIT and the net income. There are no significant items or one-timers as far as it's concerned. When you look at our tax rate and our financial income in the past, you can use similar levels to model 2022.
Got it. Thank you. I'll pass it along.
Thank you. Our next question is from Greg Palm with Craig-Hallum Capital Group. Please go ahead.
Yeah. Thanks. Just for one quick follow-up, or hopefully quick, but I want to take a stab at long-term operating margin guidance. C ommentary suggests double digit operating margins, which would be a pretty big step up relative to sort of anything you've done in the last five, six, seven years. A re you targeting a certain year or a certain level of revenue to maybe achieve this? Help us understand your thought process behind it if you can.
Thank you, Greg, for the question. When we think about the longer term, the next few years, as mentioned earlier, we expect the gross margins to go back to the level of 50%, and then which will contribute the bottom line. Then when we think about OpEx, we believe that in the next few years as revenue grow, we will be able to leverage our scale, and we already have the right infrastructure to be able to increase revenue significantly and then increase OpEx much less than the increase in revenue.
Yeah. If I may add, this is the entire strategy here. We have the infrastructure to do many, many more things and to sell many, many more products with the same infrastructure. We need the patience, but not too long. I'm not thinking, talking here about a long horizons of dozens of years. We have the infrastructure. We need to leverage the infrastructure, and that's exactly what we are doing. This is on the financial side, but the most important thing in profitability is to deliver value to our customers. We believe that no one can deliver this level of value, and we base it on very, very simple things.
One, we have laser-sharp strategy on polymer manufacturing, and we already showed it as we move from 25% to 29% of our total sales only in one year. We have well-defined growth engines that are working. The technology, the software platform, the material platform and use cases that we are developing. We have execution that it's a new level of execution within Stratasys. This year, 30 products, 2021. 30 products. This is a completely new level of execution, and most importantly, customers, our customers are loyal and trust us and work together with us in collaboration to make this happen and to create this value. When you translate it, we have double-digit operating income like Eitan described. Very optimistic on this.
Y ou're gonna see some operating leverage this year, but I don't wanna put words in your mouth, but it sounds like it only should sort of get better in the out years. I s that kind of the right way to think about it? T hat's what the math implies to get to double digit.
It's a journey of 2-3 years that you will see notably stronger results on the operating income. We are here to build the strongest 3D printing company in the industry with sustainable, profitable growth. That's exactly what we are doing. We are balancing between profitability and sustainable growth, and the result is double-digit operating income.
Okay, fair enough. Appreciate the color. Thanks.
Thank you. Ladies and gentlemen.
Thank you.
We have reached the end of the question and answer session, and I would like to turn the call back to Mr. Yoav Zeif for closing remarks.
Thank you for joining us. Stay safe and healthy. Looking forward to updating you again next quarter.
Thank you. This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
