[James Scapa, executive]

Thank you, Dave, and welcome to everyone on the call. Today, I will discuss our strong results for 2021, the recent acquisitions of World Programming and Cassini, some additional awards the company received and the overall momentum we are experiencing early in 2022.

Altair had an excellent fourth quarter and full year 2021 with all of our key numbers for Q4 and full year coming in above our guidance ranges. Our vision for driving smarter decisions with computational science and artificial intelligence is resonating with customers. Our products continue to gain market share, and we are expanding our footprint across all verticals.

Total revenue for Q4 2021 was $140.8 million, including software product revenue of $122.4 million. Adjusted EBITDA for the quarter was $24 million, representing a 17% adjusted EBITDA margin. Total revenue for the full year 2021 grew 13.2% to $532.2 million compared to $469.9 million in 2020. And software product revenue for the full year 2021 grew 15.8% to $453.7 million compared to $391.7 million in 2020.

Software product revenue for 2021 represented 85.3% of total revenue compared to 83.4% during 2020. And our recurring software license rate remained high at 92% for the year.

Adjusted EBITDA for the full year of 2021 was $85.3 million, representing growth of 49%, compared to $57.3 million in 2020. Free cash flow grew 100% in 2021 to $53.8 million from $26.8 million in 2020. Our adjusted EBITDA margin for the full year of 2021 grew to 16%, a significant improvement over adjusted EBITDA of 12% in 2020.

In December of 2021, Altair acquired World Programming, a U.K.-based technology company specializing in data analytics software used by many of the world's leading companies. World Programming brings great technology to Altair as well as a world-class team of mathematicians, statisticians, data scientists, programmers and thought leaders. World Programming's platform, WPS Analytics, supports development and execution of software applications written in popular languages such as Python or SQL and the SaaS language, including the ability to develop, compile and execute millions of models built using the SaaS language.

WPS Analytics will be incorporated into Altair's data analytics solutions suite and available under Altair Units. WPS Analytics technology integrated into the powerful low-code Altair solution creates a strong and unique offering to address the requirements within enterprises, programming data scientists and business analysts, including the ability to develop, compile and interpret SaaS language programs.

WPS Hub, combined with Altair's MLOps environment, will make it straightforward and simple to productionize machine learning models, programs written in the language of SaaS and modern data analytics applications. The acquisition of World Programming aligns with Altair's open architecture philosophy, giving customers easy access to technologies in a flexible and intuitive environment. We see the acquisition as a significant opportunity to help companies transition to modern open solutions and languages while preserving significant investments made, developing critical enterprise business applications in the SaaS language and leverage the best elements of this older technology.

As Altair broadens our data analytics offering under the Altair Units business model, we believe customers will increasingly appreciate the value we deliver, and Altair will grow to be a very significant player in this market.

We recently announced the acquisition of Cassini, a next-generation cloud-native platform for Industry 4.0. Cassini's technology manages the entire product life cycle from concept to customer through 4 key product pillars: engineering, manufacturing, quality and service, by bringing data, people and processes together in an end-to-end digital environment, creating a digital thread and providing a 360-degree view of the conceptualized product data.

Along with our technology, we bring onboard a talented team with deep experience in both the mechanical and electronics sector. Cassini software will be integrated into the Altair One cloud innovation platform to provide customers a comprehensive digital thread view of activities in the PLM value chain, especially with respect to simulation.

Altair One's best-in-class, top-down and bottom-up simulation data management capabilities, augmented with Cassini's technology, will provide a closed-loop product-validation platform to harness the power of physics and data science-based simulations. Altair sees the integration of strong data management capabilities within our platforms and seamlessly enabled as critical for customers to manage the enormous and growing complexity of traditional mechanical and electrical simulation models, simulation results, sensor data and AI-reduced order models. Altair One and Cassini each bring different and important aspects of these requirements. Both are cloud-native, and both teams are passionate about the vision.

After being awarded Newsweek's Most Loved Workplace and Inc.magazine's Best-Led Company earlier in 2021, our string of workplace and corporate awards continued in the fourth quarter of 2021. Altair Germany was named a top 22 employer by kununu, the leading employer review and branding site in the DACH region. The Economic Times, the world's second most widely read English language business newspaper, named Altair India, the best brand for 2021, 2022. We were recently named a top workplace in the U.S.A. for 2022, and Investor's Business Daily ranked Altair #50 on its list of Best 100 ESG Companies. We are proud of these awards as they recognize the enduring strength of our culture and values and the hard work our global teams put forward to help the world be a better and more sustainable place for all.

Customers increasingly recognize the value and power of Altair's data analytics suite and product set. Our data analytics team had several notable wins in the fourth quarter, including 2 7-figure, multiyear software licensing deals in the banking and financial services industry. The majority of our new enterprise customer wins leverage the units model, and many existing customers see the high-value benefits of units licensing, including concurrent users, floating licenses and access to all products and are asking to switch over.

As examples, a major bank with active users across a range of Altair's applications, including data preparation, AI, real-time analytics and visualization, recently committed to converting all its existing licenses to Altair Units. A retail customer with hundreds of users also converted their existing licenses to Altair Units.

This trend is important as we grow our footprint in the market and expand the portfolio of solutions available to customers. Beyond resulting in increased revenue, these units conversions and new deals demonstrate how our licensing model can help us disrupt the traditional data analytics market and separate us from the competition.

Momentum surrounding the convergence of computational science and AI with engineering is accelerating. In APAC, a major automotive manufacturer purchased licenses to our data analytics suite, giving their manufacturing engineering team the ability to easily connect, collect and build simulation models. An automotive supplier and long-time Altair simulation software customer began using Altair's data analytics tools within its CAE team to leverage past company data to create predictive models for use cases, including cost modeling and part-quality predictions based on manufacturing conditions. Another supplier is using our data analytics tools to compare manufacturing processes, utilizing stored data and selecting the best matches to create faster and more accurate quotes for new parts.

When historical and/or technical data is used in these types of applications, organizations often experience significantly improved financial performance. These are just a few examples that show simulation and data analytics converging, resulting in true computational intelligence.

The vision for simulation-driven design continues to evolve. The Inspire platform supports significantly more geometry creation and manipulation with every release and we believe is becoming the solution of choice for mechanical conceptual design. Our math and systems Digital Twin studio released new capability to perform complex SPICE simulations. And our Spice Solver is now also available integrated within our HPC workflow technology for highly cost-efficient IC design.

We believe our solution to design antennas and simulate complex wave propagation for 5G and ADAS applications for radar leads the market. And our solution to synthesize e-motor designs, driven by multidisciplinary simulation and optimization, are best-in-class and employed by many customers with multiple wins in the fourth quarter related to electric vehicle development.

A major customer in Europe has been embracing the Inspire platform, including SIMSOLID, as a strong basis for rearchitecting their design process driven by simulation. This customer had previously selected HyperWorks as the platform for high-level simulation and is now implementing Inspire and SIMSOLID in their new overall computer-aided design and analysis workflow.

SIMSOLID capabilities and performance are advancing quickly, and its usage continues to grow in a large proportion of our manufacturing customers. In 1 APAC country, the fourth quarter saw our SIMSOLID across the transportation sector with wins at a commercial vehicle manufacturer, a passenger vehicle OEM and at a Tier 1 supplier focused on plastics applications. Usage gains are happening both within the design engineering user base as well as several core CAE groups.

SIMSOLID played a critical role in acquiring a new AEC client in Europe where their experienced simulation users recognize the ability of SIMSOLID to dramatically speed up their processes. And its unique capabilities are being embraced in the energy sector, displacing traditional analysis codes, which are unable to match performance.

Altair was recently selected as the solution of choice for safety and crash simulation by a major rail manufacturing company, which resulted from the merger of 2 significant players in this market. Each company had used a different solution, and the newly combined company has decided to go forward only with Altair. With this victory and several other wins in the rail market, we believe Altair is emerging as the leading solution in the rail market.

Our high-performance computing business grew strongly in 2021 as the efficient usage of HPC resources and HPC application licenses on-prem and in the cloud has become an important differentiator for most companies and research institutes. We recently announced a multiyear agreement with Hewlett Packard Enterprise to offer Altair's HPC solution suite for workload and workflow management with HPE's HPC systems to support next-generation supercomputing.

The solution includes job scheduling software with robust scalable technology, capable of handling the most intense jobs while improving productivity, optimizing utilization and efficiency and simplifying administration for supercomputers of any size. The agreement strengthens a nearly 20-year relationship between HPE and Altair, and we look forward to many more years of success together.

Argonne National Laboratory announced it will utilize Altair's HPC technology across the organization's HPC systems at the Argonne Leadership Computing Facility, the ALCF, including the Polaris and Aurora supercomputers. Altair PBS Professional, which replaces the ALCF's Cobalt workload manager, will be the default workload management solution and will allow researchers to easily and more efficiently run diverse workloads and data-intensive tasks, including machine learning and simulation.

With Polaris as the leading-edge test bed system for Aurora, scheduled to be the fastest exascale computing system in the U.S. and capable of performing 1 quintillion calculations per second, it's critical to ensure that downtime is avoided as it could put research teams hundreds of hours behind completing a project. Supported by Altair's global team of HPC specialists, Altair's technology will optimize and manage thousands of node hours simultaneously and help ensure researchers can make quicker, more efficient scientific discoveries. We are honored and excited to be a part of a team enabling pure science to move forward.

Significant Altair Unlimited HPC appliance deal in the fourth quarter was deployed at a European division of a global automotive supplier. This 7-figure, multiyear deal represents the renewal of customer's predecessor system and a billings expansion of 87%. The applications include computational fluid dynamics, structures and electromagnetics.

We secured a notable Altair Unlimited HPC appliance deal at a major global material supplier. By demonstrating the scalability of our solutions and establishing successful solver benchmarks, the value proposition of Altair Unlimited was quickly evident. Solver applications, including nonlinear analysis of plastic components, material characterization, random response-based fatigue life prediction and impact analysis, this convergence of simulation and high-performance computing is a great boost to customer productivity and an excellent example of the power of Altair solutions.

I am pleased to have welcomed Sandy Carter to Altair's Board of Directors. As a pioneer in the digital business revolution and a former high-level executive at AWS for 5 years, Sandy is Senior Vice President and Channel Chief of unstoppable domains and Chairman of the Board for Girls in Tech. She was named to Forbes' Global Top 40 Marketing Masters list and CNN's 10 Most Powerful Women in Tech. Her energy, technical knowledge, executive talent, and inclusive management style are a tremendous addition to our Board.

We performed well in the fourth quarter to finish out an extraordinary 2021 against the backdrop of global uncertainty. We made excellent progress against the targets we set forward at our May 27, 2021, Analyst Day. And we experienced broad success throughout the year across many industry verticals, technology areas and geographies. We added great technology, both internally developed and from acquisitions, including S-FRAME, which offers interesting new opportunities in the fast-growing AEC sector.

2022 carries some of the same uncertainties and challenges from the prior year and some new ones, including COVID-19 variants, supply chain, inflation, tight labor marketing technology and geopolitical issues with negative effects on the macro economy. We believe we can carry our good momentum forward through this year and remain confident in the value we provide to customers, driving smart decisions and innovative products with computational science and artificial intelligence. I am sincerely appreciative of our global teams and excited about our future.

Now I will turn the call over to Matt to provide more details on our financial performance and our guidance for the first quarter and full year 2022. Matt?

[Matthew Brown, executive]

Thank you, Jim. Hello to everyone on the call, and thank you for joining us. Q4 was another fantastic quarter in what was one of the most successful years in Altair's 37-year history. We continued our streak of beating expectations across the board, notching significant wins on our way to achieving record-high revenue and adjusted EBITDA for any fourth quarter in the company's history.

Total billings for the quarter were $159.1 million, an increase of 9.0% compared to Q4 2020. Our strength in software billings was once again driven by strong new and expansion opportunities and high retention on our renewal base. We saw growth in all 3 geographic regions and particular strength in the technology and BFSI verticals.

Our data analytics products are continuing to gain traction with growth there outpacing simulation and HPC, which is a trend we saw all year. Services and other billings were in line with expectations, slightly down from Q4 in the prior year. In total, the strength in billings resulted in software product and total revenue exceeding our expectations for the fourth quarter.

Software product revenue was $122.4 million or an increase of 7.7% compared to Q4 2020. Total revenue, which includes services and other revenue, was $140.8 million or an increase of 5.5% compared to Q4 2020. Our recurring software license rate, which is the percentage of software product billings that are recurring, continues to be strong at approximately 92% for the year.

As a reminder, a significant portion of our revenues are billed in currencies other than the U.S. dollar and are, therefore, impacted by changes in FX rates. Relative to Q4 2020, our revenues were unfavorably impacted by changes in FX rates of just over $2 million during the quarter.

Non-GAAP gross margin, which excludes stock-based compensation and restructuring expense, was 78.1% in the fourth quarter compared to 76.2% in the prior year, an increase of 190 basis points, as our software revenue mix, which carries higher gross margin, increased as a percentage of total revenue. Software revenue was 86.9% of total revenue in Q4 2021 compared to 85.1% in the prior year. Over the long term, we continue to expect a general mix shift towards software product revenue as growth there will outpace services and other revenue.

Non-GAAP operating expenses, which excludes stock-based compensation, amortization of intangible assets and restructuring charges, were $87.4 million compared to $81.9 million in the year ago period. That year-over-year increase was primarily concentrated in sales and marketing expenses, reflecting increased commissions expense as a result of overperformance on software billings for the year.

Adjusted EBITDA in Q4 2021 was $24.0 million or 17.0% of total revenue compared to $21.7 million or 16.3% in the prior year quarter. This increase compared to prior year quarter as well as relative to our expectations was driven by the increase in revenue in the quarter, combined with our disciplined spending.

It's worth looking back at the entire year on the incredible progress we've made. At the beginning of the year, we laid out a vision to achieve double-digit revenue growth while expanding our adjusted EBITDA margin. Our focus paid off. We invested heavily in product development, bringing the best technology and simulation, high-performance computing, data analytics and artificial intelligence to our customers. And we invested in our sales and marketing motion, elevating our brand awareness in the market.

These efforts help drive software product revenue to $453.7 million for the year, an increase of 15.8% compared to 2020. And we achieved total revenue of $532.2 million for the year, an increase of 13.2% compared to 2020. Our non-GAAP gross profit increased $58.1 million or 16.5% to $409.2 million or 76.9% of revenue in 2021 compared to $351.1 million or margin of 74.7% in 2020.

In operating expenses, we invested in areas for growth while persistently reducing select other costs. This helped drive adjusted EBITDA to $85.3 million or 16.0%, an increase of 48.8% compared to 2020. This is a 380 basis point increase to our adjusted EBITDA margin compared to 2020. And this increase in profit is driving an increase in free cash flow, which more than doubled year-over-year to $53.8 million, which is freeing up cash to invest in our business and fuel future growth.

At the beginning of the year, we set out to grow revenue in the double digits, grow gross profit greater than our growth in revenue and grow adjusted EBITDA greater than our growth in gross profit. And in 2021, that's exactly what we were able to do. Combined with some of the competitive wins Jim mentioned a few minutes ago, several important acquisitions and notable awards, 2021 was truly a remarkable year in our history.

Turning to the balance sheet. We ended the year with $413.7 million in cash and cash equivalents, a decrease of approximately $42 million from the prior quarter. The quarter-over-quarter decrease is primarily due to approximately $49 million outflow related to our acquisition of WPL, partially offset by approximately $5 million free cash flow.

As a reminder, our cash flows throughout the year are seasonal in nature, typically with Q1 being our most significant cash flow quarter, followed by Q2.

Let's turn to guidance for Q1 and full year 2022. We've provided detailed guidance tables in our earnings press release, including reconciliations to comparable GAAP amount, which was issued after close of market today. For Q1, we are expecting software products in the range of $134 million to $137 million or year-over-year growth of 3.4% to 5.8% and full year 2022 in the range of $496 million to $508 million or year-over-year growth of 9.3% to 12.0%.

We expect services and other revenue to be down slightly compared to 2021. As a result, we expect total revenue for Q1 in the range of $152 million to $155 million or year-over-year growth of 1.2% to 3.2% and full year 2022 in the range of $568 million to $582 million or year-over-year growth of 6.7% to 9.4%.

Currency changes relative to the prior year are unfavorably impacting year-over-year Q1 total revenue growth by approximately 2 percentage points and unfavorably impacting year-over-year 2022 total revenue growth by approximately 1.25 percentage points.

From a cost perspective, we've been successful in our disciplined approach to spending and expect to carry that approach into 2022. For Q1, we expect adjusted EBITDA in the range of $36 million to $38 million or 23.7% to 24.5% of total revenue compared to $37.0 million or 24.6% of total revenue in the year ago period. And for full year 2022, we expect adjusted EBITDA in the range of $96 million to $106 million or 16.9% to 18.2% of total revenue compared to $85.3 million or 16.0% of total revenue in 2021.

In January 2022, we satisfied the existing litigation judgment against WPL of $65.9 million, which was the liability we assumed as part of our acquisition. This payment is captured in free cash flow in 2022. And as a result, we are expecting free cash flow in the range of $5 million to $12 million for 2022. We are pleased with our growth in free cash flow from core operations year-over-year, which is benefiting from our overall increase in profitability.

As a reminder, our cash flow expectations are sensitive to billings and collection patterns, which fluctuate seasonally. In particular, our historical pattern has shown a free cash inflow in the first half of the year, primarily from collections on billings from Q4 and Q1, and a smaller free cash outflow in the second half of the year. Besides the litigation settlement amount I just mentioned, we're expecting that pattern to continue this year.

In addition, today, we announced our Board of Directors has approved a $50 million share repurchase program. Having this program in place allows us to be nimble and gives us the flexibility to opportunistically return capital to our shareholders while still focusing on our primary goal of investing in our business to drive growth. We have not committed to specific share volumes or prices and view this program as being a small part of our overall balanced capital allocation strategy.

I couldn't be prouder of what this team was able to accomplish in 2021, and I'm extremely excited about what lies ahead.

With that, we'd be happy to take your questions. Operator?

[Operator]

[Operator Instructions] Our first question come line of Gal Munda from Berenberg.

[Gal Munda, analyst]

The first one is just, Jim, you mentioned a lot of enterprise deals and activity over kind of 7 figures, more than what you've said in the past. And I was just trying to see if there is a trend -- if you are seeing the trend developing, where you're becoming more of a partner rather than the tool provider to some of these customers that have been with you for a while. In other words, maybe go across different types of physics, but not just that, also bundling in things like SIMSOLID and the data side on the token side when you're kind of thinking about the revenue -- the [ new find in works ].

[James Scapa, executive]

Thanks, Gal. That's a good question. So we are -- in fact, if you look at the number of deals, large-scale deals that we're doing, there's many, many more. It's constantly increasing. We don't track that as a metric for you, but we track it internally, and the numbers are going very much in the right direction. And it is, in fact, what you're talking about. We are more strategic. In a lot of customers, we are selling the entire portfolio of our solutions, not just point solutions, typically. And that's a big part of why. So yes, thanks for the nice softball question.

[Gal Munda, analyst]

No. Okay. Just -- you would expect that to kind of continue going forward as well, I guess, from what you're saying.

[James Scapa, executive]

I do, yes. We're very focused on strategic accounts, so yes.

[Gal Munda, analyst]

Right. Right. Right. Yes. As a follow-up, maybe just thinking about -- again, the margin progression looks impressive, like you said, Matt, more than 2 percentage points improvement year-on-year. If we look into next year, you're getting very, very close to your target that you set out for the -- at the Capital Markets Day. My question here again is, if you see that progressing faster than you expected, are you going to be reinvesting in growth? Or do you think you could potentially get there a bit earlier than what you set out in May last year?

[Matthew Brown, executive]

Yes. Thanks, Gal. So you're right, I think we are well on our way to our goal of 20% exiting 2023. But if you kind of look at how we've progressed, we've been really careful about not trying to get too ahead of profit and sacrificing growth. So we wanted to be really, really balanced in investing in our technology and in our sales motion. And so from that perspective, if you kind of look at the midpoint of the guide, to about 17.6% EBITDA for 2022, that is about 2/3 of the way through where we started at 12.2% on our way to 20%. And so we feel good about that. 2/3 of the way through being 2 years out of the 3 -- on our way to a 3-year plan.

We may -- as we move along, we may continue to adapt and adjust, and there's a chance that we save a little bit extra for the bottom line. But I do think we want to make sure that we're continuing to invest for the long term. We want to be around for a nice long time.

[Operator]

Our next question comes from the line of Jackson Ader from JPMorgan.

[Jackson Ader, analyst]

The first one is for Jim on the crash and impact segment. So I think you mentioned RADIOSS is kind of becoming -- gaining some real traction in rail. I'm just curious, what is -- what's the underlying reason why your solver there would be a stronger fit for rail rather than maybe in automotive? And then, relatedly, how big is the rail vertical within that entire crash and impact solver market?

[James Scapa, executive]

So I actually don't know the answer to the size of rail, but I mean, it's obviously quite a bit smaller. It's still significant when you go outside the U.S. It's an important sector, and we've managed to capture it. I think more of it is related to relationships and all of that because we have a very strong footprint across all the products that we have.

In the world of simulation, there's -- these are sticky markets. And so the tools used for crash and impacts have been in place, and they don't tend to change a whole lot in the automotive sector. They are -- there is opportunities to do some changing. We've been very successful in China, for example, where it's a little bit more greenfield -- or it's been more greenfield in the crash and impact sector.

But the RADIOSS product is a superb product, very strong in electronics, for example, very strong in a number of different areas and obviously, very strong in automotive as well. But in rail, we managed to get a strong position. We understand the applications that they're doing there, and we have good relationships.

[Jackson Ader, analyst]

Okay. Great. And then a follow-up on the acquisitions for Matt. Number one, I mean, obviously, I assume that this litigation was known when you made the acquisition of WPL. But was that -- how did that factor into, I guess, the overall purchase price, number one? And then number two, just simply, how much do you expect those recent acquisitions to contribute to revenue in 2022?

[Matthew Brown, executive]

Yes. Thanks, Jackson. So yes, absolutely did know the litigation liability when we made the acquisition. That [ was added to ] our purchase price. Yes. It was just a function of the accounting. It just so happens that when this liability is acquired and then the cash movement goes against that liability, the cash flow ends up flowing through, cash from operating activities rather than where you might expect to see it in finance activities from an acquisition perspective.

And so it was built into our model and our deal thesis. And when you sort of adjust for that out of free cash flow, you end up with free cash flow at a range of $71 million to $78 million, which is year-on-year growth of 32% to 45%. So it's more sort of a normalized free cash flow guide.

With respect to the acquisitions and revenue that we're expecting into 2022, we're not giving precise numbers, but WPL historically had revenues in the $19 million-or-so range. And so it's not extremely significant to our full year guide. It represents a couple of percentage points. We expect that as we invest in that business and ramp that up, we'll potentially get to see some growth in future years. But we're not expecting to see growth from that number into 2022.

[James Scapa, executive]

And if I can just add to that, we -- Jackson, we do see the -- and I think Matt mentioned it in his remarks earlier, data analytics is growing very, very fast for us. If you look at simulation, HPC and data analytics, data analytics is a pretty fast growth market for us overall. So WPL and their technology just fits within that space.

[Jackson Ader, analyst]

Okay. Great. And then on the Cassini side, the other acquisition, contribution?

[Matthew Brown, executive]

Yes. No incremental revenue on that acquisition into the 2022 guide.

[James Scapa, executive]

That is a technology and equity hire, if you will.

[Operator]

Our next question will come from the line of Blair Abernethy from Rosenblatt Securities.

[Blair Abernethy, analyst]

Nice quarter, guys. Just the -- just following on the World Programming, can you just describe, Jim, how you're planning to go to market with this now? Obviously, they must have had an existing sales force and so forth. And what's sort of the -- what's the integration profile look like with the rest of your products?

[James Scapa, executive]

So we expect to integrate the products pretty nice when sales teams are already -- almost entirely integrated. The development teams are pretty integrated as well. Obviously, it takes a little more time to get everyone comfortable culturally and all that. But it's a very technical culture. It's one that fits easily sort of different than Datawatch, if you will. This is a pretty easy integration for us.

As far as how the products go, they were very, very focused on programmers. So if you think about data science in an enterprise, you have sort of 2 different types of users. You have the programmers, data science programmers who are deep down into the guts and writing code. And then you have business analysts that really want to use sort of low-code types of technology that auto-generate code and build out the applications. So they were probably more focused at the programmers. And so they support really well Python and R and SQL programming.

And then a big differentiator that they have is they have built a compiler or interpreter for the SaaS language. And that's a really nice and very unique piece of technology that is really important because a lot of companies have built a lot of code in the SaaS language. And many of these companies want to move to more modern languages, but they have a lot of important code that's still written in the SaaS language. And there's also some great capabilities that you can access.

So they support mixed language types of code. It's a really great environment for building all of that. And we see now with the integration of their tools, being able to sort of address both communities in an enterprise, the programmers and the business analysts with these tools and also support an environment, which has a mix of modern codes as well as, if you will, some legacy technology that was written in the SaaS language.

[Blair Abernethy, analyst]

Great. That's very helpful. Switching gears just a little, Jim, the -- can you just give us an update on the -- on your channel partner work that you've been doing in 2021? How that's come along? And where are you seeing some traction?

[James Scapa, executive]

So I think that, that is making progress. I'd like it to go faster, if I can be really honest. But we -- if you look at our numbers, the indirect business is continuing to gain. And more importantly, within the organization, every region is much more engaged in working with the partners, supporting the partners. And we think it's going to be really critical to get to that next level as a business. To really get to scale, you have to have an indirect component that's really substantial, and we're really committed to that. So it's coming. I'd like it to come faster, but I think it's -- there was a real progress made last year, and it's really one of our #1 priorities for 2022.

Our next question will come from the line of Matt Hedberg from RBC Capital Markets.

[Dan Bergstrom, analyst]

It's Dan Bergstrom for Matt Hedberg. Jim, maybe another softball for you. Would love to get your updated thoughts around chips in the supply chain and what you're seeing and hearing from customers. You've provided good context around this on the last several calls. Just would love an update what you're seeing as we enter '22 here.

[James Scapa, executive]

So I mean, for us, I just don't think it's a very significant impact, to be perfectly honest. Actually, the one place where we actually have a sort of direct impact is the other business line, which is that lighting business, because there's probably 1 year lead time on semiconductor components that -- when we're ordering them. So that is a pretty big impact. And it gives me a view into what many of my customers are really sort of managing and dealing with, particularly if you have a new line product where you haven't established the supply chains.

So for example, our older line lighting products, we have much less difficulty but newer designs, newer products where we're establishing those supply chains. That's much harder. But again, for Altair and the software business, and I suspect for most of my compatriots, I don't think it's a huge impact for us, and we certainly haven't seen that.

[Dan Bergstrom, analyst]

That's great. And then software was really strong again this quarter. I know the strength is broad-based, but are there any particular areas of strength that you could point out or maybe drill down into for us?

[James Scapa, executive]

I mean I think it's the obvious areas. We do -- first of all, it is really across all regions, all 3 regions with really strong growth, actually. Data analytics is stronger in the U.S. because it's -- we spent more time with that, but we are investing to take it more and more overseas, and I think that's going to shift. The WPL business has a lot of overseas component, and I think that's going to help. Technology and defense and off-road are pretty strong particular markets for us, but auto and aero are still growing very substantially, actually. So it is really across the board. Sorry for that boring answer.

[Dan Bergstrom, analyst]

No, it's great to hear.

Our next question will come from the line of Ken Wong from Guggenheim.

[Nancy Liu, analyst]

This is Nancy on for Ken. Congrats on the quarter. Two questions from me. So services, you guided just slightly down next year. So wondering how we can think about that business going forward in fiscal '22 and beyond, in the out-years, if there's any dynamics we should be aware of as we build our models. And then secondly, as we look at first quarter, was there any kind of meaningful pull-forward activity in 4Q to be aware of?

[James Scapa, executive]

I'll let Matt take that.

[Matthew Brown, executive]

Yes. Yes, happy to take that. So when we look at our services and other business, you really have to kind of get underneath it. And it's the CES business that we're seeing struggle a bit as we head into 2022, there's still a little bit of a hangover from COVID, actually, so we're seeing an impact there, particularly in Q1. As we make our way through the year, it starts to level off a bit and get a bit better. But we do expect, at least in the long term that, that business is going to come back around and continue to grow in the sort of low to mid-single-digit range.

Software-related services, that's included in that services and other, it's actually doing pretty well. So it's really kind of CES that's bringing that overall bucket down.

And I forgot your follow-up question. I apologize. Can you repeat that?

[Nancy Liu, analyst]

That was helpful. Was there any pull-forward activity in 4Q?

[Matthew Brown, executive]

Right. No, there wasn't any substantial pull-forward activity. When we're heading down at the end of the year and the end of the quarter, you can't always predict when deals are going to close. But we did not see any meaningful activity crossing quarters at least outside of norm.

[Operator]

And our next question comes from the line of Bhavan Suri from William Blair.

[Dylan Becker, analyst]

It's Dylan on for Bhavan. I appreciate you squeezing us in here, and congrats on the strong quarter and into the year. Maybe a 2-parter. And so we've seen you guys kind of offer up some of the, I think, the PCB design capabilities for free here with some new users. It sounds like that's being kind of viewed favorably and giving a broader opportunity maybe with some of the less technical design-focused engineers. Are you thinking at all about potentially expanding that functionality, offering kind of maybe other tools across the platform with this more kind of like premium-based approach as an additional way to onboard some of these users?

And then, maybe for Matt, as a follow-on to that, is there any kind of metrics or anything you could share around adoption or usage of the free solution? And how maybe some of those conversions to paid has trended as well?

[James Scapa, executive]

So I mean, strategy around the -- and you're talking about the Altium free solution that we've put out in the market, there's a lot of interest. So that is super positive. It's way too early to sort of measure that at this point. But we are trying to grow the visibility of our offering, and we think there's a lot of value in what we're offering there. And so yes, I mean, it's a strategy to get visibility. It's a strategy to get some new users, a very large community, and we expect to see a good deal of traction there.

We're seeing a lot of traction also just for the solution in large enterprise customers sort of separate from the Altium freemium-ware for now. And the whole offering for PCB continues to sort of evolve, and we're feeling really good about it.

[Matthew Brown, executive]

Yes. As far as tracking metrics, it is just too early. We're excited about the opportunity, and we do think it's a really promising market. And honestly, in all likelihood, it's probably not something that we're going to be providing metrics on in the future. But at this point, it is really just too early.

[Operator]

And I'm not showing any further questions in the queue. I'd like to turn the call back over to Jim Scapa for any closing remarks.

[James Scapa, executive]

Really just want to express appreciation to my team, great year. Matt, first year as CFO, did a fantastic job, and really, everyone else on my team did as well. And also appreciation to the support from all the investor community as well.

So yes, thanks, everyone. Looking forward, very, very excited about the future. I feel like we're in a great place. So thank you.

[Operator]

And this concludes today's conference call. Thank you for participating. You may now disconnect. Everyone, have a great day.
