Hi, everyone. The fourth quarter represented a strong end to a transformative year for Ouster, with 86% revenue growth over the fourth quarter of 2020 and continued industry-leading gross margins that clearly validate our diversified strategy of providing state-of-the-art solutions to multiple rapidly accelerating industry verticals. Our growth rate and strategic position reinforce our confidence that Ouster is poised for continued market share gains. We have a significant lead over earlier-stage pre-revenue competitors and superior technology to legacy players. This is proven by our growth and ability to deliver positive and meaningful gross margin, even as the industry matures. As the lidar market continued to mature, we're confident that our multi-market approach will enable Ouster to capture significant shares of the automotive, industrial, smart infrastructure, and robotics verticals.
These four target industries represent an aggregate addressable market of $8.6 billion by 2025 and Ouster is well-positioned to deliver meaningful growth in each vertical. We're confident in our ability to win in automotive with our multi-sensor suite, as well as our advantage in the industrial, robotics and smart infrastructure verticals which represent an even larger near-term opportunity. The first 100 days of Ouster Automotive have exceeded our expectations, and our two teams are now fully integrated, with each adding highly complementary expertise. Design, development and validation work are on track with the timeline we've previously shared. Our automotive negotiations are progressing well and our pipeline of deals continues to expand as we engage more OEMs. We're excited to share more details on our progress today and over the coming months.
Ouster has the most differentiated lidar technology with our OS and DF series digital lidar platforms, backed by a leading patent portfolio, scalable manufacturing and growing supplier relationships. We have the most diversified business with over 600 customers over the last 12 months across multiple markets, allowing us to build toward a stable run rate while investing in products and solutions to capture new growth opportunities. We have a proven ability to execute, nearly doubling our revenue, more than tripling the number of sensors shipped and adding 58 strategic customer agreements or SCAs year over year, all while operating with the highest hardware gross margin of our public peer set.
In short, we're confident that we have the team, the technology and the strategy to make Ouster the leader in lidar. As the eyes of autonomy, we're poised to have a large-scale impact on the safety and sustainability of our society through the multitude of applications and industries that we touch. Anything that moves or that monitors moving objects has the potential to become more intelligent and efficient with digital lidar. With that, I'd like to turn the call over to our CFO, Anna Brunell, to provide a full update on our 2021 results and 2022 guidance before I dive into Ouster's growth strategy.
Thank you, Angus. Ouster had a breakout year, one in which we maintained and delivered on our 2021 guidance, and we will not stop there. We believe the pace of digital lidar adoption is only accelerating across each of our industry verticals: automotive, industrial, smart infrastructure and robotics. We have the right technology, Ouster's digital lidar, an outstanding team and a multi-market strategy to take advantage of both near and long-term revenue opportunities and extend our market leadership throughout the upcoming year. Let me turn to our financial results. Ouster delivered record quarterly results, generating $11.9 million in revenue, up 86% over the fourth quarter of 2020 and up 53% sequentially, demonstrating the acceleration of our business. We shipped over 2,400 sensors in Q4, nearly a 200% increase over the fourth quarter of 2020.
Further, we increased our total signed strategic customer agreements to 68 through the fourth quarter. Consistent feedback from these customers indicates that they chose us over other lidar companies because we offer superior performance and deliver industry-leading reliability. Our digital technology has fewer parts than our analog competitors, meaning greater reliability in real-world applications and less risk in our manufacturing process. This translates directly to our financial results. We continue to deliver industry-leading gross margins, reaching 30% in the fourth quarter and continue to reduce our cost per unit sold in spite of the ongoing supply chain challenges which resulted in temporary purchase price variance related to bulk purchases and expedited shipment fees in order to keep up with product demand.
We have a phenomenal manufacturing and operations team that managed to secure our source materials, scale production of our new OS sensors powered by the L2X chip, ship a record number of sensors with short lead times and without shipping delays and strategically drive down our cost per unit sold during a year in which manufacturing proved challenging for many of our competitors. We delivered on our full year 2021 guidance with $34 million in revenue and 27% gross margin. We made a commitment to our shareholders and executed on that commitment by almost doubling our revenue in 12 months. With approximately 6,500 sensors shipped in 2021, we tripled the number of sensors sold over the prior year, amounting to over 10,000 sensors shipped to date.
These results help us illustrate the three key takeaways that separate Ouster from the rest of the lidar industry. Our differentiated technology, our diversified business and our proven ability to execute. Ouster has a diverse group of over 600 customers across over 50 countries purchasing and using our sensors in the last 12 months. Our 68 signed SCAs accounted for 20% of Ouster's 2021 revenue and represents approximately $500 million in contracted revenue opportunity through 2025. We see strong customer and SCA growth across each of our four verticals and throughout the Americas, Asia Pacific, Europe and the Middle East. The automotive vertical which includes robotaxi, robotrucking, shuttles and buses and consumer ADAS, accounted for 34% of sensors shipped in 2021.
This includes Robotic Research which uses Ouster's OS sensors across a number of its commercial and defense platform offerings, including 5 OS sensors on the modular unmanned Danner vehicle for the agricultural, industrial and defense markets. Industrial accounted for 25% of sensors shipped in 2021, including Vecna Robotics, which signed a strategic customer agreement to utilize approximately 3,000 OS digital sensors to equip self-driving pallet trucks, tow tractors and lift trucks through 2025. We saw the strongest quarter-on-quarter growth in smart infrastructure which accounted for 15% of sensors shipped in 2021 to support 86 deployed projects within our intelligent transportation, smart places and security submarkets. Finally, robotics accounted for 26% of sensors shipped in 2021, including Serve Robotics which recently signed a binding commitment through 2023, along with a non-binding forecast for additional sensors through 2025 as it scales its delivery fleet.
This diverse group of SCAs exemplifies the success of our multi-market approach, as Ouster is not dependent on a single or small handful of customers or even one market vertical with revenues hitting in 2025 and 2026 but rather on both auto and non-auto opportunities that offer revenues and attractive margins in both the near and long term. These strong financials are a direct result of our targeted capital allocation plan. In 2021, we committed to using our public offering cash proceeds to accelerate our product roadmap, increase software offerings and build out a global sales and marketing team. These initiatives helped to nearly double revenue growth year over year, increase our market share across our four market verticals and extend our technical advantage over our peers.
In particular, we have grown our commercial team across the Americas, EMEA and Asia Pacific markets, and brought on experienced leaders to develop a focused sales organization geared towards ramping our sales pipeline. We released the first software development kit for lidar, expanded our partner platform and invested in verticalized software solutions to drive new customers and higher margin revenues. Sense Photonics, our first major acquisition, accelerated our automotive product roadmap by more than a year and immediately positioned us in late round negotiations with multiple OEMs and tier ones. We were able to make these strategic investments while maintaining a cash balance of approximately $184 million at the end of the fourth quarter.
We generated higher gross margin compared to Q3 but additional cash burn versus the third quarter was driven by non-recurring items related to the Sense Photonics acquisition, working capital headwinds to support growing sales and mitigate supply chain shortage risks and manufacturing equipment purchases. We aim to reduce our quarterly cash burn rate in the first quarter of 2022 as the $11 million fourth quarter 2021 non-recurring cash impact from the Sense Photonics acquisition rolls off. This past year was a breakout year for Ouster and we expect this rapid growth to continue in 2022. For the full year 2022, we aim to double revenue, targeting a range of $65 million-$85 million and maintain positive gross margins, targeting a range of 25%-30%.
The broad range in projected revenue reflects the continued evolution of the industry with customer timelines that can shift and evolve. With this, we do anticipate some variability in the first quarter of 2022 as compared to the previous quarter. As we progress throughout the year, we expect to narrow our projected range. As we move into 2022, we expect our quarterly operating expenditures, excluding stock-based compensation, to be roughly in line with the fourth quarter of 2021 as we continue to support ongoing product development goals, including a full quarter of acquired headcount costs, offset by one-time fees associated with the Sense acquisition in the fourth quarter of 2021. We expect capital expenditures to increase by approximately $5 million year-over-year. Since the formation of Ouster Automotive, our deal flow has both accelerated and expanded.
These high volume opportunities require some additional investment in the development and manufacturing process as we work with OEMs and tier ones to integrate our solid state digital lidar in mass production vehicles. Further, we are investing in other areas of the business like product and vertical specific certifications and software tools and value-added solutions which will drive high margin deals over the long term. Resulting from our digital technology, we remain confident in our ability to continue to meaningfully reduce cost per unit sold faster than our average selling price over the course of 2022. Through significant 2021 customer growth and our 68 established SCAs, Ouster now has greater insight into our customers' forecasted long-term purchasing needs, including several multiyear binding purchasing commitments.
Through our SCAs, we are building a business based on greater visibility, predictability and stickiness and remain confident in our long-term strategy and the immense opportunities we are pursuing through our multi-market approach. We think about our long-term business growth from both a top-down and bottom-up perspective. We see an $8.6 billion total addressable market opportunity by 2025 across our four verticals which shows we have significant headroom to grow with our customers as the market expands into this TAM. From a bottom-up, every one of our 68 SCAs includes a three to five year forecast provided directly from the customer. In aggregate, a metric we call contracted revenue opportunity which we see roughly doubling year-over-year. We're encouraged by what we see with SCAs and there's still potential to win additional new business and expand further with existing customers.
Whether we look bottoms up or top down, the numbers paint an incredibly exciting vision for the immense multi-market opportunity we're pursuing, backed by the doubling of our revenue that we've seen over the past year. These growth expectations are supported by our accelerated automotive momentum generated by the formation of Ouster Automotive, the upcoming launch of our L3 chip which we believe will unlock new opportunities in every vertical we serve, achieving industrial, automotive and safety certifications to expand market opportunities and displace legacy sensors and a more robust software ecosystem which will enable us to accelerate lidar adoption and provide customized solutions for our customers. These advancements will be a catalyst for growth across each of our core verticals. 2021 provided us with an excellent foundation on which to grow and I cannot wait to drive towards our goals in 2022.
I'd now like to turn it back over to Angus to speak through key opportunities driving our 2022 guidance and overall growth.
Thanks, Anna. Digital lidar is permeating our roads and cities, how we manufacture goods and every link along the global supply chain. This widespread adoption is driven by three key trends that span our target verticals. First, a generational shift in what consumers and regulators expect from next-generation vehicles, including increased safety, efficiency and advanced driver assistance functionality. Second, accelerated industrial automation to improve workplace safety and productivity and counter ongoing supply chain challenges. Third, increased investments in smart infrastructure to build safer and more efficient transportation systems. We're in the midst of a generational shift in the automotive world. Consumers and regulators are expecting more from vehicles than ever before, including new levels of safety, driver assistance and electrification. As a result, automakers are reimagining the automobile around these expectations. Camera and radar-based systems work in limited scenarios and fall far short of higher levels of autonomy.
Comprehensive lidar coverage around the vehicle promises to close the performance gap to deliver improved safety and driver assistance systems. Ouster's affordable, flexible and high-performance multi-sensor lidar suite delivers exactly what OEMs need to bring safe ADAS-enabled vehicles to market. However, when it comes to passenger vehicles and series production, the best technology in the world is simply a curiosity unless it comes at a price point that allows for true mass adoption. This is where Ouster's simple CMOS-based digital lidar approach truly separates from the pack. Today, Ouster can offer pricing on our DF series sensors that makes lidar standard fit on next generation luxury and mass market vehicles. The next five years will determine the winners in automotive and I'm confident that our technology and team is poised to make Ouster Automotive the leading lidar solution.
The second macro trend driving growth across our business is the widespread automation of millions of industrial vehicles across the global supply chain, from mining and agriculture to ports, distribution yards, warehouses, trucking and last mile delivery. Collectively, these applications have the potential to rival series production runs in automotive and with even higher margins. This trend has only accelerated in the wake of the global supply chain challenges and COVID-19 pandemic. Ongoing labor shortages, inflation and public health concerns are increasing the pace of lidar adoption as industries across the supply chain seek to improve workplace safety and improve the efficiency of their operations with automated technologies. We're seeing a huge demand from customers looking to adopt digital lidar, whether they're established multi-billion dollar OEMs looking to update their fleets like Sandvik and Konecranes or upstarts like Vecna and Outrider, bringing autonomy to mature industries.
Ouster is working with both to help address worker shortages and increase safety and efficiency through automation. The third trend driving growth is government-led initiatives to build safer, more sustainable cities by modernizing public infrastructure and transportation systems. With the over 1 million signalized intersections and 85 million surveillance systems in the U.S. alone, we see significant potential upside beyond the $2.8 billion TAM for digital lidar in the smart infrastructure vertical. We're at the very beginning of a broad societal shift that will bring greater intelligence, connectivity and safety to public and private spaces and transportation systems. For example, deploying just two lidar sensors at an intersection can replace expensive and unreliable ground loops and adds analytics that reduce idling time for vehicles and increase pedestrian safety. In ports, our digital lidar is being used to increase productivity and safety in handling shipping containers.
In metro stations, lidar sensors are being used to count foot traffic and to analyze crowd patterns without compromising citizens' privacy. Last year, Ouster was selected for 110 smart infrastructure projects in over 20 countries, many of which represent large-scale growth opportunities over the coming years. We view the acceleration in market demand as a signal that the smart infrastructure vertical is starting to ramp. These projects represent nearly 3,000 digital lidar OS sensors for initial deployments across the intelligent transportation systems, smart places and security submarkets. The social impact of these programs is significant. They increase road safety and efficiency, improve quality of life and enhance the sustainability of our communities.
The U.S. Infrastructure Investment and Jobs Act and the new National Roadway Safety Strategy are great examples of the current administration's strategic focus to fund these programs and we're seeing a similar trend play out across Europe, Asia and the Middle East. These three macro trends are driving widespread adoption of lidar technology and Ouster is well-positioned to meet customer requirements across each of our verticals. Last quarter, we introduced the Ouster Automotive DF Series of flexible and scalable high-performance solid-state lidars for high-volume automotive programs. Our breakthrough DF Series is impressive in terms of performance and unique in offering multiple ranges and fields of view for automakers to design into their vehicles. We shipped short and long range DF0 and DF2 prototypes to a number of automotive customers last quarter, as well as our strategic OEM partner.
We also achieved another major milestone with the introduction of our L2X chip, the highest performing chip we've ever designed with two times the processing power and twice the data output as the L2 chip. This chip advancement enabled us to offer our most reliable and rugged sensors yet for superior 3D perception through fog, rain, dust, and snow and made each sensor in our OS product family even more capable. The L2X powered sensors unlock new market opportunities and revenue in the fourth quarter and are expected to drive additional growth across our verticals in 2022. Finally, we launched features and sensor capabilities with another over-the-air firmware update and rolled out a new version of our software development kit, or SDK, that's being adopted by an increasing number of our customers. I'll come back to this critical piece of our software ecosystem later on.
While 2021 was an important year for product releases and scaling for Ouster, we expect 2022 to be even stronger with more products spanning hardware and software than ever before. Ouster's diversified digital lidar strategy has taken strides. We have a clear plan to grow our business, further differentiate our product offerings, capture market share and extend our market leadership. Foremost, I view 2022 as the year of the L3 chip. The L3 will offer the most significant performance upgrade ever for our OS series. The L3 chip is the culmination of years of R&D inside Ouster and keeps us on the exponential performance path of Moore's Law. The technology inside the L3 is incredible and brings the same backside illumination advancements that revolutionized the camera sensor industry to the high-performance lidar industry for the very first time.
As with our L2 and L2X chips, the L3 chip is a fully custom ASIC fabricated on a standard CMOS process. The significant performance improvement provided by this proprietary chip design cannot be replicated with off-the-shelf chip offerings. I simply cannot wait to unveil it to our customers as planned later this year. While the L3 chip will power OS sensors, our solid-state Digital Flash silicon is powering all of our DF sensors. In line with our digital roadmap, our next generation Digital Flash chip will be taped out later this year and serve as the backbone of our automotive-grade multi-sensor DF suite for series production programs starting in 2025. We remain on track with select A samples in the first quarter of 2022 and expect to establish digital lidar as the predominant lidar technology in automotive this year.
While product features and performance upgrades will be major growth drivers for our business for the foreseeable future, we have a significant additional axis on which to catalyze new business and this is the vertical specific product and safety certifications which we are pushing. It's well understood that high volume automotive applications require stringent quality and safety certifications, notably ASIL B and IATF 16949. We believe Ouster is uniquely positioned to achieve these certifications across our entire portfolio of OS and DF sensors. In fact, our contract manufacturer, Benchmark, achieved IATF 16949 two years ago at our Thailand facility and has already passed several automotive OEM audits. Outside of automotive, there's an established market for SIL 2 and NEMA TS2 safety certified industrial and smart infrastructure lidar that is primed to convert to advanced 3D lidar.
There is already nearly a $1 billion market for legacy 2D industrial lidar sensors today. We understand from our customers that there is significant latent demand for digital lidar that can reduce costs and enable advanced autonomy by displacing outdated safety sensors. We're excited about the anticipated developments this year which have the potential to open up these high margin opportunities. Finally, we are building a robust software ecosystem built on three foundational pillars that will be a major catalyst for growth. The first is a best-in-class software development experience that provides the resources and tools to reduce our customers' times to test, validate and integrate our sensors. The second is an expanded partner platform to bring targeted solutions to our customers. The third are verticalized software solutions that drive new customers and higher margin revenues.
In 2021, we invested in building out a best-in-class software development experience that serves as the foundation of our entire software ecosystem. These tools accelerate our customers' time to autonomy, enabling them to test and validate our sensors faster and bring their applications to market sooner. Since releasing the Ouster SDK in Q2 2021, we've seen tremendous customer adoption and will continue to ship major additional advancements in 2022. We also invested in building out an expanded partner platform that includes over 40 software and integration partners to date and growing. These partners help us win new customers, streamline sensor integration and accelerate our customers' time to market across each of our target industries. Finally, Ouster has a tremendous opportunity to bring to market verticalized software solutions to complement our partner ecosystem and developer tools.
Our customers solve repeatable problems using our sensors across a wide variety of use cases every day and there is a clear need for solutions in the market that solve these repeatable use cases. We see these software solutions creating a new high-margin revenue stream, as well as accelerating lidar sensor adoption by lowering the barrier to entry to a new set of less technical customers. I can't wait to share what we have in store later this year. In closing, Ouster continued to execute this year. We had a record fourth quarter and we achieved our 2021 guidance. This year, we intend to double our revenue while maintaining industry-leading gross margins. We've laid out an aggressive plan for 2022 to grow our business, further differentiate our products, and extend our market leadership. The team is continuing to execute as we've done in the past.
With that, I'd like to open it up for Q&A.
Thank you. We will now begin the question-and-answer session. To ask a question, you may press star then one on your phone. If you are using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star one again. When called upon, please limit yourself to two questions. Our first question today comes from Blayne Curtis with Barclays. Your line is open.
Hey, good afternoon and thanks for taking my question. Maybe just first, on the outlook for 2022, you know, I think Anna talked about some variability for Q1. I didn't know what that meant but then if you could just address that a little bit. I'm just curious, you know, you started to break out the percent in verticals. I don't know if you're gonna continue to do that but any color between those verticals as to how you're thinking about the growth this year?
Well, I can take the first one. This is Anna. Good to talk to you again, Blayne. On the variability in Q1, you know, much like we saw in the prior year, we saw the Q1 number, you know, aligning closer to the Q4 number than to seeing a step-up, a significant step-up in growth. We were just kind of guiding that we'll see the Q1 ramp, potentially have a little bit of variability in it rather than just a straight trajectory.
Good to talk to you, Blayne. Thanks for the question on the vertical breakdown. Hope you appreciated the breakdown at all. That's the first time we've done that, giving the percentage units per vertical. Now that we've done that, you know, we're committed to doing that on an annual basis and we're gonna look to, you know, whether we do it on a quarterly basis but haven't committed to that yet.
Great. I definitely appreciate it. Just any color or thoughts between those four verticals as to, you know, what's driving the growth this year?
Yeah, absolutely. I mean, the three major catalysts that we outlined are the major growth drivers for the first three verticals. In automotive, we have, you know, the adoption of electrification and then autonomy and increased safety in automotive and the kind of the receptiveness to that technology set, lidar specifically. In industrial, it's the automation of the global supply chain that we've seen kind of top to bottom. You can't talk to an industrial OEM at this point and not hear about an automation strategy of some kind or another. That's whether it's a legacy company or a major established company in the space like an Amazon or a John Deere or a Caterpillar of the world or, you know, a newcomer in the space like Outrider or Vecna.
Everyone has an automation strategy and it you know far more often than not centers around LiDAR or requires LiDAR as a component. The last you know in smart infrastructure I think that's the industry where we had a huge amount of growth quarter-over-quarter in smart infrastructure and we mentioned that in the script. We see that having huge potential upside. When you look at the potential unit kind of sockets where LiDAR could go and displace legacy sensors whether they're cameras or radar sensors or ground loops or just make something that was not intelligent before intelligent like a crosswalk there are millions of sockets that we could put digital LiDAR in in the next five years. There's such a significant investment at the government level.
There's funding available but it's greenfield and so it's a lot of new emerging applications. That's why we see so much upside is because it's not fully understood yet. It's a lot of new and emerging applications. A lot of growth across all our verticals, robotics being the last which is more of a catchall and combines a number of our subverticals and is growing for its own reasons. A lot of emerging applications in robotics as well.
Thanks. Just one for Anna. I appreciate the revenue and gross guidance, margin guidance for the year. I was curious how you're thinking about managing OpEx for the year, if there's any color you can give. I think at one point you gave the EBITDA guidance but just anything in terms of OpEx growth or EBITDA would be awesome.
Yeah, I mean, I think we gave some clues to what we're gonna be entering 2022 with in terms of in my scripted remarks, we talked a little bit about that there were about $11 million of non-recurring Sense fees that we won't see from Q4 to Q1. Then we would see a full quarter of the Sense employees 'cause we had a partial quarter in Q4 going into Q1. We talked about that we expected, you know, OpEx going into 2022 to look similar to the fourth quarter.
Okay.
That would be net of stock-based compensation, just the baseline fees.
Appreciate it. Thank you.
Your next question comes from the line of Itay Michaeli with Citi. Your line is open.
Great, thanks. Good afternoon, everyone. Angus, want to go back to the topic of the non-auto certification and the opportunities you see there. I think the industry opportunity may be around $1 billion. You mentioned an appetite from some of the customers there to upgrade sensors and of course you've got the L3 chip coming. Just curious, you know, roughly what the timing is on some of those certifications. Once you're there, you know, how quickly can you book additional revenue? Is this really more of a 2023, 2024 kind of revenue opportunity as you unlock some of these markets post-certification?
Yeah, sure. Thanks for the question, Itay. So, you know, I think that the timeline, actually the Ouster strategy around certifications that unlock these new kind of land and expand opportunities with existing customers or just unlock completely new certified lidar markets to us, that is paying dividends already today to some degree, which is, it's been a great benefit to be able to go to a customer, you know, say a robotic forklift lift customer and say, "We can replace some of the lidars on your platform today with a consolidated set that's more affordable and more performant.
You can also expect that in the future, any of the certified lidar that you have to keep on your platform by law, that we can replace those in the future as well and make your system simpler, make it more cost-capital efficient, lower cost for you." That's all because we have this clear roadmap that's pretty unique in the industry because we have this unified product portfolio and we have this roadmap towards certifying all of our products for all of the major certifications required across our verticals. All that being said, it's paying dividends today to some degree, but you can expect in the next year or so for that to be an even bigger catalyst as we actually achieve some of these certifications.
We're not giving an exact timeline on when we're achieving each one of the certifications, basically for competitive reasons. It's, you know, don't have to hold your breath significantly. Again, we're already seeing some of the benefits.
Great. One other kind of new business question. I think the release mentions a goal of winning at least one OEM production program this year. Anything else you can share in terms of, is it one sensor? Is it surround? Is it kind of L2 plus features? Maybe the region and then and the volume. Whatever you can share on that would be super helpful.
Yeah, absolutely. One of the major updates is that from the automotive side we've been pushing forward with the production versions of our DF sensor lineup. We announced the Digital Flash sensors, fully solid-state lineup. Now we're moving into the design phase of the Digital Flash silicon that's gonna move into production and replace the gen one silicon that we have in house today. That silicon is capable of the Digital Flash product lineup being single sensor installs for like L2 and L2 plus applications. It can also be multi-sensor suites for either advanced L2 plus systems that have much more capability or L3 powered systems. Regardless of application, our goal is to be the most affordable solution for either of those.
I would say it's split. You know, a lot of the deals that we're working on are actually multi-sensor suites that are pushing towards L3 capability. There still is a contingent of automakers that are focused on typically near term opportunities that are just single sensor installs. You know, we have the strategy and the product line and the affordability and the performance that allows for these more advanced, more feature-rich L3 multi-sensor suites. Because of that, we also are able to offer highly competitive and affordable single sensor solutions for kind of the L2 plus feature set. Yeah, out of the 5 deals that we've previously announced that we're working on, both of those requests are represented.
You know, one of the significant reasons why we're in the mix is because we can be so competitive on pricing for either.
That's great. That's all very helpful. Thank you.
Your next question comes from the line of Sam Peterman with Craig-Hallum Capital Group. Your line is open.
Hi, guys. Thanks for taking my question. Congrats on the quarter. I just wanted to ask on the SCA pipeline, curious where you saw kind of the strength coming this quarter and increases coming. I wanted to make sure I heard you right that you saw that pipeline dollar value doubling in 2022. If that's the case, kind of based on the run rate you've been at for the average value per SCA, you'd need to add, you know, probably close to 100 SCAs. Obviously, that can change with, you know, one or two larger customers thrown in there. Is that kind of how you're thinking about it for 2022?
I think that's when you're talking about the SCAs and we talked about seeing kind of a roughly doubling in our customers' forecasts, you know, we're talking about not necessarily doubling the number of SCAs. We're just talking about looking ahead to what our customers are telling us their businesses are growing at that rate. That's what we were referencing. We weren't trying to impute like a certain number of signed SCAs needed in the future. That was based off of customers that are in existence today.
Yeah, I wanna make sure that makes sense because it's a really important point and it's a really positive sign for the business. That doubling is when we ask a customer for a three to five year forecast in aggregate. You know, our customers are roughly doubling their forecast, you know, what they're gonna purchase from us, year over year. That's the doubling. We see the doubling of growth in the established customer base based on the, you know, the direct information they're providing. A separate goal of ours is to increase the number of SCAs that we have, you know, every year but we haven't given any indication of what our expectation necessarily is there. Obviously, we intend to grow the SCA count this year.
Gotcha. Okay. Thanks for
Did that make sense? Yeah.
Yeah. Thanks for clarifying that. Then I wanted to ask one on the gross margin. That guidance, obviously you guys, you know, have industry-leading margins like you talked about and you'd expect, you know, ASPs to come down, units to go up, over time. Kinda the way you framed that was you saw, you know, you saw units going down faster than ASPs are going up but your margin guidance is pretty flat here. I just wanna get some color on what's built into the gross margin guidance. Are there other factors, you know, maybe a mix shift to certain product lines or end markets, that are affecting the guidance or, just any color on that would be helpful.
Yeah, I mean, I think we are still seeing our cost of goods sold decline at a faster rate than our ASPs. For the annual results, it was about a 35% decline on ASPs and a 53%, I think, decline on cost of goods sold. We are still meeting our initiatives to you know to target the margins or to achieve the margins that we've targeted. I think going forward into next year, we're being a little bit perhaps cautious related to supply chain issues and allowing ourselves a little bit of room there. Generally, we do still continue to see the margins developing in the way that we're expecting.
Okay, thanks. That does it for me.
Your next question comes from the line of Joseph Osha with Guggenheim. Your line is open.
Joseph Osha now. Hello, everyone.
Hi, Joe. Good to hear from you.
Yeah, yeah. Just a couple questions. First, on your comments on the L2X and the L3. Just looking at the L2X and the picture of it kind of looks like you've got three big pieces of silicon there, the digital logic, the detectors and the emitters. Then I look at the sort of little picture of L3 and it's sort of a gray square. I'm wondering, is the idea as you go to L3 that we might see greater integration of these different pieces of silicon? Can you comment on that?
I can't really give more details on the L3. I mean, the reason we have it grayed out is because, you know, there are things that you can figure out about a chip by looking at it and we wanna keep the surprise for when we announce all the products. The general idea is that we mentioned this, we're taking advantage of a really significant advancement in semiconductor technology, backside illumination, for the very first time with L3. That increases both the, you know, key kind of raw sensing metrics, like how well it can perceive light. We're also combining that with architectural improvements in the digital logic.
We have, you know, as you pointed out, we have over 100 million transistors of digital logic that's running the lidar sensor co-located with that pixel array. Improving both is the goal, you know, every time that we take out a chip. It's a really significant advancement. It really is the most significant advancement we've ever had in a chipset b ut we're gonna save some of the improvements for when we release the products that are powered by the L3 later this year.
We'll get a more detailed look at L3 architecture later this year.
Absolutely.
Okay. Now completely different question, just thinking much longer term. You know, obviously we're talking about the margin outlook this year but just, you know, thinking about as you look out to 2025 and, you know, we've been having lots of these conversations. It seems as if the industrial part of this business, you know, as the software ramps and so forth, really possibly could still get to a, you know, 55%-60% gross margin someday b ut, you know, at the same time, all the, you know, conversations I and the other people on this call have had on automotive, you know, that we should probably think about that still as, you know, maybe a mid- to kinda mid-30s% gross margin business looking at the way automotive is.
Is that still a reasonable, long-term set of expectations to have?
Yeah, I think, Joe, like we've been giving guidance for the next year and I think, you know, what's really important here is that, you know, with our guidance, we're gonna do what we say we're going to do and really build trust with the investor community and the street. I think, you know, if you look out further, it is an immense multi-market opportunity and we are very excited about our four verticals and the growth in both the near term and the long term. I do agree with you, there's gonna be some variability in margins across verticals but overall I think it's gonna be a great business. You know, we do agree with you. We think probably auto is gonna be the lowest margin vertical.
You know, we've said before maybe around 25% is probably accurate for automotive while the other verticals we see as higher margin opportunities. I think, you know, it's an immense multi-market opportunity and we're really excited about our customers' growth and the visibility that that's giving us into the future. You know, greater visibility, greater predictability, greater stickiness in our business. We're really excited about the growth that we're seeing and the margins that we're seeing today.
Okay. Thank you. Just one final quick one, if you can comment. Is Shauna McIntyre still running automotive or has there been some kind of change there?
Yeah. Actually, Shauna has moved on to a new CEO role as of just last month. You know, on that note, I actually wanna thank her for her role in the acquisition. She was integral in the successful integration of the two teams. Ouster Automotive is in great hands with the kind of established team that was under her. There's no change to our outlook or our strategy or any commitment we have to our automotive partners or customers.
Okay, thank you for that.
Thanks for asking.
This does conclude our question and answer session. I'd like to turn the conference back over to Angus Pacala for any closing remarks.
Yeah, absolutely. I mean, I just wanna highlight, 2021 was a fantastic year for us. You know, we doubled revenue. We built a world-class commercial and auto teams like we said we would. We accelerated our hardware and software roadmaps, 3x unit shipments, dropped COGS faster than ASPs, signed 58 SCAs, grew our customers to over 600 and over 10,000 units shipped worldwide and we delivered on our full year 2021 year guidance. We did all of that in the midst of a global pandemic and, you know, a disruption in the semiconductor supply chain that's pretty unprecedented. You know, to say I'm proud of our team and what we've accomplished is a complete understatement. I'm incredibly proud and, you know, we're not stopping there.
We've aligned Ouster with these big catalysts in the global economy, new shifts in autonomy, or in automotive, automation in the global supply chain and industrial and investment in the safety of and efficiency of our world in smart infrastructure. You know, Ouster's products address those trends head on. We have this digital technology and diversification across industries and we've proven that we're able to execute on, you know, do what we say and say what we do. I think Ouster's future in 2022 and beyond is incredibly bright. I wanted to thank everybody for tuning in and everyone that asked questions and have a great rest of your day.
Ladies and gentlemen, the conference is now concluded. Thank you for attending today's presentation. You may now disconnect your lines at this time.
