Altair and Altair partner applications are also available through Altair One, our modern, secure, cloud innovation gateway, to download software, execute 
interactive applications or batch compute intensive jobs. Altair One also enables users to easily create and access compute clusters on the fly, manage files 
and data between the cloud and on-prem storage, and develop web applications. 

Physics Simulation and Concept Design

Altair’s design, modeling, and visualization tools allow for advanced physics attributes to be modeled and rendered on top of object geometry in high 
fidelity. These tools are becoming more integrated, user friendly, design-centric and relevant earlier in the development process. 

Our industrial and concept design tools generate early concepts to address requirements for ergonomics, aesthetics, performance, manufacturing feasibility, 
and cost. These tools are all driven by simulation and machine learning algorithms. We believe these products are emerging as a market force with the 
potential to eclipse traditional computer-aided design (CAD) in both the mechanical and electronics worlds.

At the core of Altair’s simulation software portfolios are mathematical software “solvers” that use advanced computational algorithms to predict physical 
performance. Optimization leverages these solvers to derive the most efficient solutions to meet desired complex multi-objective requirements. 

Altair’s solvers are a comprehensive set of fast, scalable and reliable physics algorithms for complex problems in linear and non-linear mechanics, fluid 
dynamics, electromagnetics, motion, discrete elements, systems and manufacturing simulation.  We invest continuously to improve the speed and accuracy 
of our solvers by leveraging the latest mathematical techniques and computer hardware available. 

Addressing the large market of designers, design engineers, and manufacturing engineers who are not experts in simulation is important toward increasing 
the use of simulation in design processes. Altair has several technologies focused on this market, including Inspire and SimSolid for mechanical design and 
Pollex for electronic systems and printed circuit board design.

We believe the breakthrough technology of SimSolid is game-changing and delivers extremely easy to model, fast, and accurate simulation results for 
complex designs. SimSolid is especially relevant for simulation-driven design and seeing rapid adoption in many customer environments. We are investing 
significantly in SimSolid and have released numerous new features and solution types including non-linear structural and thermal analysis. We are 
increasingly targeting SimSolid to address complex simulations in the electronic systems market for printed circuit boards and semiconductors.

Altair’s optimization technology combined with superior multi-physics and multi-domain simulation is a key differentiator and spans our product offering. 
We believe customers using our technologies gain a sustainable competitive advantage by developing better products in less time. 

Models are increasingly required to deliver performance across a range of physics, including mechanical systems, communication and control, printed 
circuit boards, and combinations of these at various levels of fidelity. Altair’s math and system design tools help engineers to quickly explore requirements 
and performance throughout the design process.

We believe Altair’s solutions are compelling due to their openness and usability, and their ability to develop signal-based controls, mixed physics models, 
and electronics all within one environment and at varying levels of fidelity to support decision making in each stage of a product’s lifecycle. For example, 
our multi-disciplinary models may include mechanics, fluids, electronics, and software among other technical elements, and encompass a scope of products 
ranging from components to IoT-enabled “systems of systems.” By employing varying degrees of fidelity, we aid the modeling process where 
computational requirements or data availability might otherwise prove to be obstacles. 

A key strength to Altair’s math and systems solutions is allowing development organizations to move seamlessly in this multi-discipline, multi-component, 
multi-detail space while integrating models from various authoring tools. With a broad range of 

4

 
Table of Contents

multi-physics solvers based on an open-system approach, a strong set of model reduction techniques can be employed toward IoT-enabled product 
development, which can then be carried forward into device management and application development. 

We believe Altair’s tools for simulation of communications and control, data analytics, and real-time data streaming are particularly relevant as more 
products are connected and collecting data to operate in complex environments.

High-Performance Computing

Altair’s high-performance computing software applications are designed to maximize the efficient utilization of customers’ complex compute resources and 
streamline the workflow management of compute-intensive tasks. The quantity of data collected, stored, and processed is growing significantly, and our

as modeling, simulation, artificial intelligence, and visualization in fields such as banking, financial services, insurance, weather prediction, bio-
informatics, electronic design analysis, product development and lifecycle management.    

Altair’s high-performance tools manage and optimize where and when jobs are running and how storage is accessed and managed for customers and 
research institutes. We believe that HPC is increasingly mission critical for organizations around the world. Predictive modeling and analysis are 
computationally intensive and computing environments increasingly rely on a mix of on-premise and cloud resources.  

Our powerful and easy to use solutions help IT administrators and business decision makers maximize throughput and minimize costs by leveraging 
sophisticated scheduling algorithms. Altair’s HPC solutions are designed to enable seamless shifting of workloads from on-premise data centers to the 
cloud, and between different cloud providers, depending on cost or resource availability including managing spot computing purchases. We also deliver

Altair’s research and development team consists of approximately 1,400 people worldwide. We maintain research and development centers with specific 
technical expertise in several geographies throughout the Americas, Asia-Pacific, Europe, the Middle East and Africa. 

Our research and development efforts relating to our software focus on three areas:

•

•

Physics Simulation and Concept Design:  At the core of Altair’s simulation software portfolio are mathematical software “solvers” that use 
advanced computational algorithms to predict physical performance. Altair initially specialized in structural simulation, and our solvers are now 
a comprehensive set of fast, scalable and reliable physics algorithms for complex problems in linear and non-linear mechanics, fluid dynamics, 
electromagnetics, motion, discrete elements, systems and manufacturing simulation.  Altair also invests to “couple” our solvers to simulate 
multiple physics domains simultaneously and is considered a market leader in the development of optimization technology, which drives solvers 
to find solutions to complex multi-objective design problems. R&D is also conducted to leverage HPC technology for these compute intensive 
applications. Solver and optimization development is conducted principally by researchers with advanced degrees in engineering, physics, 
computer science, and mathematics.

The graphical applications used to construct and visualize simulation models require continuous R&D in the areas of data structures, 
computational methods, graphics, geometric modeling, mesh generation, and user interface design. Altair’s modeling tools are becoming more 
design-centric and are adopting some of the capabilities of traditional CAD while leveraging simulation and optimization technology to drive 
design decisions rather than just simulate designs. Specific areas of R&D include handling large scale models of highly detailed and complex 
products, developing new methods to derive design geometry from optimizations, and unifying the modeling environment for multi-physics 
simulation. Adapting modeling and visualization technology for cloud deployment is also an area of active development as is supporting virtual 
and augmented reality hardware. Simulation-driven design requires tools to generate early concepts addressing requirements for ergonomics, 
aesthetics, performance, and manufacturing feasibility. We believe these tools are emerging as an alternative to traditional CAD tools and will 
enable the democratization of simulation capabilities for designers and engineers who are not simulation specialists.  

Our industrial and concept design tools generate early concepts to address requirements for ergonomics, aesthetics, performance, manufacturing 
feasibility, and cost. These tools are all driven by simulation and machine learning algorithms. 

High-performance Computing:  Altair’s high-performance computing software applications are designed to maximize utilization of complex 
compute resources and streamline the workflow management of compute-intensive tasks for applications such as data analytics, AI, modeling 
and simulation, and visualization in fields such as financial services, weather prediction, bioinformatics, electronic design analysis, product 
development and lifecycle management. 

Altair develops best-in-class HPC workload management technology for large scale, highly parallel job environments as well as solutions for 
chip design workloads which require massive numbers of jobs to be spawned and managed for relatively short durations. We also develop 
powerful orchestration capabilities to manage extremely large-scale workflows with complex dependency management for applications in 
electronic design automation, artificial intelligence and other areas.

We develop solutions for both CPU and GPU architectures and support all the major computer vendors. This requires ongoing collaboration with 
hardware suppliers who depend on our solutions to make their products run efficiently for customers.

Much of our more recent R&D investments allow customers to easily move and manage workflows in hybrid compute environments of on-
premise and cloud resources. 

The quantity of data collected, stored and processed is growing significantly, and our HPC technology has evolved to support big data and IO 
intensive environments with storage-aware scheduling. We also develop and deliver powerful orchestration capabilities to manage extremely 
large-scale workflows with complex dependency management for applications in electronic design automation, artificial intelligence and others.

business analysts with low-code solutions as well as programmers with a rich development environment including support for modern languages 
like Python and traditional languages like SAS and SQL. We deliver a rich toolset for data preparation, data science, MLOps, and visualization 
that fuel engineering, scientific, and business decisions. We develop solutions allowing users to develop machine learning workflows with best-
in-class decision tree technology and scoring algorithms, and innovative approaches to AutoML and explainable AI. We develop and release new 
software on a regular basis to support customers with enhancements and other requested features and technologies for data preparation, data 
science and visualization. In addition, we have integrated our data analytics capabilities into a modern, cloud-based solution to deliver a more 
unified user experience. This solution includes important enterprise level capabilities such as security, data discovery, collaboration, and 
operationalization of user developed machine learning workflows to gain deep insights quickly. 

Altair’s solutions support smart connected product development including device enablement, data capture and management, edge orchestration, 
digital twins, and application development for connected devices. Our software is used to design and optimize IoT devices and connectivity, and 
for modeling in-service product performance. We are investing to deliver an end-to-end solution for customers developing connected products. 
We believe our products operate well as a complete and integrated suite and are open such that they are designed to work seamlessly with other 
IoT or data analytics solutions in a disaggregated fashion. Altair’s Toggled LED lighting subsidiary is an important learning and deployment 
environment as we gain real-world experience with these technologies and share that knowledge with our customers. 

Our digital twin platform supports product development for IoT through a math-based programming environment, multi-disciplinary system 
modeling, and control system development, and is an important ongoing research and development effort. We believe that AI technology is 
transforming engineering design and process development, leveraging both synthetic data from simulations and rapidly growing databases of 
sensor data from field operations.   

We support our own high-level matrix-based numerical computing language, as well as more commonly used general purpose programming 
languages, like Python and Tcl, in an interactive programming environment for all types of math operations. We expect to add more language and 
library support, broaden the math libraries, and integrate these products more deeply with Altair’s other software.   

In order to maintain and extend our technology leadership and competitive position, we intend to continue devoting significant effort to our research and 
development activities. 

Sales 

We serve customers in the product lifecycle management, simulation, data analytics, AI, and high-performance computing markets. Our primary users are 
highly educated and technical engineers and data scientists. 

We engage with our enterprise customers through Altair’s experienced direct sales force. We are increasing our use of inside sales and indirect channels to 
more efficiently address a broader set of customers in consumer products, electronics, energy and other industries.  We organize cross functional teams 
globally to focus on our largest vertical markets such as Automotive, Aerospace, Technology and BFSI, and the largest customers in these vertical markets.

Approximately 86% of our 2023 software revenue was generated through our direct global sales force. These sales teams interact with key decision makers, 
engage deeply with users of our products by leveraging a team of Altair’s technical specialists, and work with user-group managers and executives to 
ensure they are maximizing the utility of our software solutions. We have been expanding our direct sales team including our inside sales operations 
aggressively to reach more customers and market verticals.

Our direct sales force is responsible for developing new customers, ensuring high recurring rates from our existing customers, and expanding the use of 
Altair and partner products within customers’ environments through continuous training, support, and consulting engagements. Each of our field sales 
professionals are supported by technical specialists with deep knowledge of our products and the broader product development domain. We believe this 
approach differentiates Altair from our competitors, as our focus on establishing a strong working relationship with the user community has led to expanded 
usage of Altair and APA partner products. Our direct sales force is organized by vertical markets and geographic regions, consisting of Americas, EMEA, 
and APAC.

Table of Contents

We leverage indirect sales channels especially in APAC and Eastern Europe and have been investing to extend our reseller relationships in all markets. 
Approximately 14% of our 2023 software revenue was generated through our growing network of indirect channel partners, resellers, and system 
integrators.

Data Analytics, AI, IoT, and Smart Product Development

The data analytics and AI market is segmented by industry verticals where specific domain expertise is important for success. Altair’s primary data 
analytics and AI customer base is BFSI organizations along with finance departments across most industries including manufacturing. As we cross sell into 
Altair traditional manufacturing customer accounts, we are targeting finance departments, leveraging the expertise of our financial markets sales and 
technical teams, as well as engineering departments looking to apply data analytics and AI to improve designs, manufacturing, warranty, and in-service 
operations. We are leveraging our existing direct and indirect sales channels to support greater market opportunities.

High-Performance Computing Solutions 

Altair’s HPC solutions are sold by our global strategic sales force with sales overlay support from Altair HPC sales specialists and application engineers. 
We have original equipment manufacturer, or OEM, arrangements for these solutions with most of the major hardware companies. We believe these 
arrangements reduce competition, grow our market share and improve sales efficiency. 

We offer Altair PBS Professional as both an open source and a commercial solution. Commercial sites generally license the commercial version along with 
support. However, many universities, government agencies and small commercial sites prefer the open-source version as their work often needs to be freely 
available for societal benefit. Large government and research installations generally still purchase support and often pay for specific development. 

Licensing 

There are two licensing methods we employ to deliver our software solutions:  

• Most products are available under Altair Units, our unique, patented units-based licensing model.

•

A small subset of our products is available on a node-locked, or hardware specific, and named-user basis. This is especially true for our high-
performance computing solutions.

Altair pioneered Altair Units, a patented units-based subscription licensing model for software and other digital content. This units-based subscription 
licensing model allows flexible and shared access to our offerings, along with more than 150 partner products. Our customers license a pool of units for 
their organizations giving individual users access to our portfolio of software applications as well as our growing portfolio of partner products. We believe 
our units-based subscription licensing model lowers barriers to adoption, creates broad engagement, encourages users to work within our ecosystem, and 
increases revenue. This, in turn, helps drive our recurring software license rate which has been on average approximately 91% over the past five years. 
Historically, approximately 60% of new software revenue comes from expansion within existing customers.

Marketing

Altair’s global marketing team of approximately 100 people is focused on generating new business opportunities by driving awareness, deepening customer 
engagement, and developing content specific to technical fields and industry verticals. Our corporate marketing programs include social media, earned 
media, publications, blogs, white papers and case studies. Our regional marketing program supports working relationships with our user community 
through education, participation in local industry events, Altair technical conferences, and webinars.

We provide marketing support to our ecosystem of resellers and third-party technology partners on both a corporate and regional level.

In order to continue to drive growth and extend our market position, we intend to continue to invest significant resources into our marketing initiatives.

Customers

As of December 31, 2023, we had more than 13,000 customers worldwide. Our simulation and HPC customers are primarily large manufacturing 
enterprises, with a growing presence in small and mid-size companies. Our data analytics and AI customers include banks, credit unions, BFSI, and health 
care organizations along with finance and engineering departments across most industries including manufacturing. 

Automotive and aerospace represent our largest industries, including 15 of the world’s leading automotive manufacturers and 10 of the world’s leading 
aerospace manufacturers. Other important industries include technology, BFSI, heavy machinery, rail and ship design, energy, government, life and earth 
sciences, and consumer electronics. No single customer, nor any of our resellers and OEMs, accounted for more than 2% of our 2023 software billings. In 
2023, 36%, 31% and 33% of our software billings were attributed to the Americas, EMEA, and APAC, respectively. Our global billings allocation is based 
on usage across each geography. Billings consists of our total revenue plus the change in our deferred revenue, excluding deferred revenue from 
acquisitions during the period, and is discussed under Non-GAAP Financial Measures included in Part II, Item 7, Management’s Discussion and Analysis 
of Financial Condition and Results of Operations of this Annual Report on Form 10-K.

For a summary of our financial information by geographic location, see Note 17 of Notes to consolidated financial statements in Item 15, Part IV of this 
Annual Report on Form 10-K, which is incorporated by reference.

Competition

The market for simulation, HPC, data analytics, and AI software is highly fragmented. Our primary competitors include companies such as Dassault 
Systèmes, Siemens, Ansys, MSC Software (a Hexagon company), SAS Institute, and Alteryx. Many are large public companies, with significant financial 
resources. In addition to these competitors, we compete with many smaller companies offering similar software applications.

We believe the breadth and depth of Altair’s software offering is unique and no single competitor addresses our entire solution set. The units model further 
extends this advantage with a growing APA marketplace of third-party software. 

Our simulation solutions including modeling, visualization and solvers are noted in the market for their ability to handle large and complex models. Our 
software applications deliver high performance and high scalability, including massive parallelization, which is extremely important in the high-end 
simulation market. Altair is a leader in integrating optimization technology across all our products, including multi-disciplinary applications. 

We believe our solutions for data preparation, data science and AI are extremely strong, easy to use, powerful, and broadly adopted and have several unique 
capabilities including handling large, complex data sets coupled with our ability to intelligently import unstructured data. 

To ensure customer success and deepen our relationships with them, we engage with our customers to provide consulting, implementation services, 
training, and support, especially when applying optimization. We believe these services, combined with our ability to leverage HPC as the industry 
transitions to cloud computing, positions us for future success.

We compete on a variety of factors including the breadth, depth, performance, and quality of our technical solutions. We believe our patented units-based 
subscription licensing model provides us with a competitive advantage by lowering barriers to adoption, creating broad engagement, and encouraging users 
to work within our ecosystem. 

Intellectual property

We believe that our intellectual property rights are valuable and important to our business. We actively protect our investment in technology through 
establishment and enforcement of intellectual property rights. We protect our intellectual property through a combination of patent, copyright, trademark 
and trade secret protections, confidentiality procedures, and contractual provisions. The nature and extent of legal protection associated with each such 
intellectual property right depends on, among other things, the type of intellectual property right and the given jurisdiction in which such right arises.

As of December 31, 2023, we have 290 issued patents worldwide and 15 published patent applications worldwide. These patents and patent applications 
seek to protect proprietary inventions relevant to our business. We intend to pursue additional patent protection to the extent we believe it would be 
beneficial and cost effective. Additionally, we are the registered holder of a variety of trademarks and domain names that include “Altair” and similar 
variations.

10

 
Table of Contents

Nonetheless, our intellectual property rights may not be successfully asserted in the future or may be invalidated, circumvented, or challenged. In addition, 
the laws and enforcement of the laws of various countries where our products are distributed do not protect our intellectual property rights to the same 
extent as United States laws. Our inability to assert or enforce our intellectual property rights could harm our business.

From time to time, we receive claims alleging infringement of a third-party’s intellectual property rights, including patents. Disputes involving our 
intellectual property rights or those of another party have in the past and may in the future lead to, among other things, costly litigation, diversion of time, 
money and resources to develop or obtain non-infringing products, or delay product distribution. Any significant impairment of our core intellectual 
property rights could harm our business or our ability to compete.

Our products are licensed to users pursuant to signed license agreements or ‘click through’ agreements containing restrictions on use, duplication, 
disclosure, and transfer. Cloud-based products and associated services are provided to users pursuant to online or signed terms of service agreements 
containing appropriate restrictions on access and use.

We are unable to measure the full extent to which piracy of our software products exists. We believe, however, that software piracy is and can be expected 
to be a persistent problem that negatively impacts our revenue and financial results. We believe that our predominant subscription-based business model 
combined with the change from desktop to cloud based computing will shift the incentives and means by which software is pirated.

In addition, through various licensing arrangements, we receive certain rights to intellectual property of others. We expect to maintain current licensing 
arrangements and to secure additional licensing arrangements in the future, as needed and to the extent available on reasonable terms and conditions, to 
support continued development and sales of our products and services. Some of these licensing arrangements require or may require royalty payments and 
other licensing fees. The amount of these payments and fees may depend on various factors, including but not limited to the structure of royalty payments, 
offsetting considerations, if any, and the degree of use of the licensed technology.

Employees

As of December 31, 2023, we had more than 3,200 in-house employees and more than 200 on-site Client Engineering Services employees globally. More 
than two-thirds of our employees are in the United States, India, Germany and UK. None of our employees in the United States are represented by a labor 
organization or are party to any collective bargaining arrangement. In some of the European countries in which we operate, we are subject to, and comply 
with, local labor law requirements in relation to the establishment of works councils. We are often required to consult and seek the consent or advice of 
these councils. We have never experienced a work stoppage and we believe our employee relations are collaborative. We continually recruit for top talent 
and invest in our global workforce to fuel diversity, professional and personal growth, and innovation.

Diversity

We believe that empowering each individual's authentic voice encourages an entrepreneurial mindset. We have worked to create a culture of inclusion 
where diversity and experiences are embraced and essential to our success and long-term growth. We recognize and believe that everyone deserves respect 
and equal treatment. We believe that we comply in all material respects with all applicable U.S. Federal, state, local and international laws governing 
nondiscrimination in employment in every location in which the Company operates. Our goal is to assure that all applicants and employees are treated with 
the same high level of respect regardless of their gender, ethnicity, religion, national origin, age, marital status, political affiliation, sexual orientation, 
gender identity, disability, or protected status.

We are proud to offer employee resource groups (ERGs) and Special interest groups that promote diversity and inclusion at Altair and within our 
communities, including:

•

•

•

Altair Black Employee Resource Group (ABERN) - Established to collaborate with allies in mentorship, outreach, and professional 
development opportunities within Altair while supporting recruitment and retention efforts of black employees in Altair. ABERN is 
committed to engaging Altairians from around the world to support this goal.

Altair's Women in Technology (WiT) - Develops and empowers women at Altair and amplifies their unique perspectives, ideas, and 
experiences to establish a more diverse, more inclusive workplace. We are committed to attracting top talent and ensuring each and every

Human capital

We monitor human capital metrics such as recruitment, attrition, learning & development, and diversity. Our strong brand, innovative product portfolio, 
cross-industry expertise, and culture support our ability to recruit and retain top talent. Our executive staff, including our CEO, are highly engaged with our 
workforce through podcasts, town halls, and other methods of outreach enabled by the accelerated adoption of virtual communication platforms and face-
to-face engagement.

Altair’s culture has historically embraced flexible work arrangements. Whenever possible, our employees are given the opportunity and flexibility to 
schedule their own working hours and work-from-home schedule within the limitations set by our management in order to meet our goals and objectives. 
This program operates on a goal-oriented basis and is constructed on mutual trust between employees and their managers. We believe in trusting our 
employees, by offering them with flexibility on work arrangements so they embrace and maintain work life balance, while continuing to be productive.

To attract, retain and motivate the best talent, we offer competitive total rewards programs, including market-competitive compensation, health & wellness 
programs, paid time off, parental leave, tuition assistance, employee training & development, and mentoring programs.

We seek to provide market competitive health & wellness programs across all of our global locations. Our goal is to offer best health practices to help guide 
wellness decisions and encourage our employees to achieve a healthy, sustainable lifestyle. We do so by fostering health & wellness through education, 
preventative care, comprehensive benefits programs and support. Ensuring compassion, approachability, and confidentiality in our health & wellness 
communication and care is very important. Our benefit programs are designed and maintained locally with intelligence from local market trends and 
employee feedback. The effectiveness and competitiveness of these programs is measured and monitored annually. In addition to our health & benefit 
program, we also provide virtual health and wellness programs, such as meditation, mental health tips, and information sessions by medical professionals.

Information technology and cybersecurity 

Our business and support functions utilize information systems that provide critical services to our employees and customers. Led by our Chief Information 
Security Officer, our team of professionals manage and support our communication platforms, transaction-management systems, and analytics and 
reporting capabilities. We use both third-party cloud services and off-site, secure data centers in North America and Europe for our core applications.

Information security and privacy are important concerns, with an escalating cyber-threat environment and evolving regulatory requirements driving 
continued investment in this area. We continue to evaluate and assess our systems in the changing regulatory environment.

We have in place, and seek to continuously improve, a comprehensive system of security controls, managed by a dedicated staff. Periodically, we engage 
the services of third parties to perform security penetration testing and may update our security controls in response. We also provide our staff with regular 
security risk awareness, education, and training. Despite these efforts computer viruses, hackers, employee misuse or misconduct, and other internal or 
external hazards including natural disasters could expose our data systems to security breaches, cyberattacks, or other disruptions.

We have incident response and business continuity plans for our operations. Our recovery plans include arrangements with our off-site secure data centers 
and cloud infrastructure. We believe we will be able to utilize these plans to efficiently recover key system functionality in the event that our primary 
systems are unavailable.

Sustainability and environment

As the world is demanding safer, more efficient, and innovative products and processes, our vision is to help customers drive decisions leveraging the 
convergence of simulation, HPC, and AI. By helping our customers, we help to reduce the environmental impact of goods and services across a broad array 
of industries worldwide. Altair published its most recent sustainability report in April 2023.

We believe that our software technology and consulting services are by their very essence at the core of designing a healthier and more sustainable future 
for humanity. These efforts include:

Acquisitions

We have acquired 51 companies or strategic technologies since 1996, including 22 in the last five years. These acquisitions brought strategic IP assets, and 
talented developers with expertise in disciplines in the areas of electronics, material science, crash and safety, manufacturing simulation, industrial design, 
photorealistic rendering and data analytics. Products that are commercially available as a result of these acquisitions include Altair PBS Works, Radioss, 
Evolve, AcuSolve, SimLab, Embed, Multiscale Designer, FEKO, FLUX, Thea Render, SmartWorks, ESAComp, SimSolid, Monarch, Panopticon, EDEM, 
PollEx, PolyFoam, Grid Engine, Mistral, Breeze, S-FRAME, Altair SLC (formerly WPS Analytics), EEvision, StarVision, RapidMiner, Genesis, and 
OmniV.

During 2023 we acquired the following:

•

•

OmniQuest: In September 2023, we acquired OmniQuest, a Michigan based optimization software company. OmniQuest's flagship product, 
Genesis, is an advanced structural analysis and optimization software that uses the finite element to solve problems with many variables and 
constraints. OmniQuest will enhance Altair's optimization leadership in the market driving lightweight and structurally efficient designs across 
the globe.

OmniV: In July 2023, we acquired the OmniV technology from XLDyn, LLC. OmniV is a vendor agnostic MBSE requirements management 
solution. This technology will enhance Altair's ability to engage in projects involving digital twins, simulation data management, and engineering 
data analytics.

For further information about our acquisitions, see Note 4 of the Notes to consolidated financial statements in Item 15, Part IV of this Annual Report on 
Form 10-K.

Seasonal variations

We have experienced and expect to continue to experience seasonal variations in the timing of customers’ purchases of our software and services. Many 
customers make purchase decisions based on their fiscal year budgets, which often coincide with the calendar year. These seasonal trends materially affect 
the timing of our cash flows, as license fees become due at the time the license term commences based upon agreed payment terms that customers may not 
adhere to. As a result, new and renewal licenses have been concentrated in the first and fourth quarter of the year, and our cash flows from operations have 
been highest in the first and second quarter of the succeeding fiscal year.

Backlog

We generally enter into single year term-based software licensing subscription contracts for our solutions. The timing of our invoices to the customer is a 
negotiated term and thus varies among our subscription contracts. For multi-year agreements, it is common to invoice an initial amount at contract signing 
followed by subsequent annual invoices. At any point in the contract term, there can be amounts that we have not yet been contractually able to invoice. As 
we generally enter into single year subscription contracts for our platform, backlog is not significant.

Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring and 
enforcing employment and labor laws, workplace safety and environmental laws, privacy and data protection laws, financial services laws, anti-bribery 
laws, import and export controls, federal securities laws and tax laws and regulations. In certain foreign jurisdictions, these regulatory requirements may be 
more stringent than those in the United States. These laws and regulations are subject to change over time and thus we must continue to monitor and 
dedicate resources to ensure continued compliance. We strive to maintain compliance with all applicable laws and regulations and to anticipate future 
regulatory developments. For additional information, see “Risk Factors - Risks related to legal or regulatory matters.”

Risks relating to our business and industry

We have experienced significant revenue growth and we may fail to sustain that growth rate or may not grow in the future.

We were founded in 1985 and launched our first commercial software in 1990. Our growth has primarily been attributed to the increasing sales of our 
simulation, high-performance computing and data analytics technologies to enhance decision making, product performance, compress development time, 
and reduce costs. Revenue from our software segment has historically constituted a significant portion of our total revenue. Our revenue growth could 
decline over time as a result of a number of factors, including increasing competition from smaller entities and well-established, larger organizations, 
limited ability to, or our decision not to, increase pricing, contraction of our overall market, the manner in which the markets for our products, including our 
data analytics products, evolve or our failure to capitalize on growth opportunities. Other factors include managing our global organization, revenues 
generated outside the United States that are subject to adverse currency fluctuations, uncertain international geopolitical landscapes and the acquisition of 
businesses which may grow more slowly than our business. Accordingly, we may not achieve similar growth rates in future periods, and you should not 
rely on our historical revenue growth as an indication of our future revenue or revenue growth.

If we cannot maintain our company culture of innovation, teamwork, and communication, our business may be harmed.

We believe that a critical component to our success has been our company culture, which is based on our core values of innovation, envisioning the future, 
communicating honestly and broadly, seeking technology and business firsts, and embracing diversity. We have invested substantial time and resources in 
building a company embodying this culture. As we continue to grow, we may find it difficult to maintain these valuable aspects of our corporate culture. 
Any failure to preserve our culture, or embed our culture in our acquired businesses, could negatively impact our future success, including our ability to 
attract and retain personnel, encourage innovation and teamwork, and effectively focus on and pursue our corporate objectives.

If our existing customers or users do not increase their usage of our software, or we do not add new customers, the growth of our business may be 
harmed.

Our software includes a comprehensive open architecture solution for simulation, high-performance computing, data analytics, and artificial intelligence. 

Our future success depends, in part, on our ability to increase the:

•

•

•

number of customers and users accessing our software;

usage of our software to address expanding design, engineering, AI, computing and analytical needs; and/or

number of our applications and functionalities accessed by users and customers through our licensing model.

Our future success may also depend upon the degree to which the evolution of our units licensing model is accepted by our current and potential customers.  

In addition, through our Altair Partner Alliance, or APA, our customers have access to additional software offered by independent third parties, without the 
need to enter into additional license agreements.

If we fail to increase the number of customers or users and/or application usage among existing users of our software and the software of our APA partners, 
our ability to license additional software will be adversely affected, which would harm our operating results and financial condition.

Our ability to acquire new customers is difficult to predict because our software sales cycle can be long.

Our ability to increase revenue and maintain or increase profitability depends, in part, on widespread acceptance of our software by mid- to- large-size 
organizations worldwide. We face long, costly, and unpredictable sales cycles. As a result of the variability and length of the sales cycle, we have only a 
limited ability to forecast the timing of sales. A delay in or failure to complete sales could harm our business and financial results, and could cause our 
financial results to vary significantly from period to period. Our sales cycle varies widely, reflecting differences in potential customers’ decision-making 
processes, procurement requirements, budget cycles and the specific software or products being purchased, and is subject to significant risks over which we 
have little or no control, including:

•

longstanding use of competing products and hesitancy to change;

17

 
Table of Contents

•

•

•

•

•

•

customers’ budgetary constraints and priorities;

timing of customers’ budget cycles;

need by some customers for lengthy evaluations;

hesitation to adopt new processes and technologies;

length and timing of customers’ approval processes; and

development of software by our competitors perceived to be equivalent or superior to our software.

To the extent any of the foregoing occur, our average sales cycle may increase, and we may have difficulty acquiring new customers.

Reduced spending on product design and development activities by our customers may negatively affect our revenues.

Our revenues are largely dependent on our customers’ overall product design and development activities, particularly demand from mid- to- large-size 
organizations worldwide and their supplier base. The licensing of our software is discretionary. Our customers may reduce their research and development 
budgets, which could cause them to reduce, defer, or forego licensing of our software. To the extent licensing of our software is perceived by existing and 
potential customers to be extraneous to their needs, our revenue may be negatively affected by our customers’ delays or reductions in product development 
research and development spending. Customers may delay or cancel software licensing or seek to lower their costs. Deterioration in the demand for product 
design and development software for any reason would harm our business, operating results, and financial condition in the future.

Our business largely depends on annual renewals of our software licenses.

We typically license our software to our customers on an annual basis. In order for us to maintain or improve our operating results, it is important that our 
customers renew and/or increase the amount of software licensed on an annual basis. Customer renewal rates may be affected by a number of factors, 
including:

•

•

•

•

•

•

•

•

•

our pricing or license term and those of our competitors;

our reputation for performance and reliability;

new product releases by us or our competitors;

customer satisfaction with our software or support;

consolidation within our customer base;

availability of comparable software from our competitors;

effects of global or industry specific economic conditions;

our customers’ ability to continue their operations and spending levels; and

other factors, a number of which are beyond our control.

If our customers fail to renew their licenses or renew on terms that are less beneficial to us, our renewal rates may decline or fluctuate, which may harm our 
business.

We believe our future success will depend, in part, on the growth in demand for our software by customers other than simulation engineering 
specialists and in additional industry verticals.

Historically, our customers have been simulation engineering specialists. To enable concept engineering, driven by simulation, we make our physics solvers 
more accessible to designers by wrapping them in powerful simple interfaces. We believe our future success will depend, in part, on growth in demand for 
our software by these designers, which could be negatively impacted by the lack of:

•

•

•

continued and/or growing reliance on software to optimize and accelerate the design process;

adoption of simulation technology by designers other than simulation engineering specialists;

continued proliferation of mobility, large data sets, cloud computing and IoT;

18

 
Table of Contents

•

•

our ability to predict demands of designers other than simulation engineering specialists and achieve market acceptance of our software or 
products within these additional areas and customer bases or in additional industry verticals; or

our ability to respond to changes in the competitive landscape, including whether our competitors establish more widely adopted products for 
designers other than simulation engineering specialists.

If some or all of this software does not achieve widespread adoption, our revenues and profits may be adversely affected.

Our ability to grow our business may be adversely impacted by difficulties we may experience in integrating recent acquisitions or in integrating future 
acquisitions.

We believe that our recent acquisitions result in certain benefits, including expanding our portfolio of software and products and enabling us to better serve 
our customers’ needs. However, to realize some of these anticipated benefits, the acquired businesses must be successfully integrated. The success of these 
acquisitions will depend in part on our ability to realize these anticipated benefits. We may fail to realize the anticipated benefits of these acquisitions for a 
variety of reasons, including the following: 

•

•

•

•

•

•

•

•

•

•

•

failure to successfully manage relationships with new or potential customers;

failure of existing customers to accept new service and product offerings from us;

revenue attrition in excess of anticipated levels;

unanticipated incompatibility of technologies and systems;

failure to leverage the increased scale of our business quickly and effectively;

potential difficulties integrating and harmonizing financial reporting systems;

the loss of key employees;

failure to effectively coordinate sales and marketing efforts to communicate the capabilities of our enhanced portfolio of software and 
products; 

failure to combine product offerings and product lines quickly and effectively;

failure to convert an increasing amount of new or acquired customer relationships revenue from perpetual to annual recurring revenue 
streams; or

failure to effectively invest in further sales, marketing, and research and development efforts that lead to increased revenues.

We face significant competition, which may adversely affect our ability to add new customers, retain existing customers, and grow our business.

The market for simulation, data analytics, and high-performance computing software is highly fragmented. Our primary competitors include companies 
such as IBM, Dassault Systèmes, Siemens, Ansys, MSC Software (a Hexagon company), and Alteryx. Many are large public companies, with significant 
financial resources. In addition to these competitors, we compete with many smaller companies offering similar software applications.

A significant number of companies have developed or are developing software and services that currently, or in the future, may compete with some or all of 
our software and services. We may also face competition from participants in adjacent markets, including two-dimensional, or 2D, and three-dimensional, 
or 3D, CAD, and broader PLM competitors and others that may enter our markets by leveraging related technologies and partnering with or acquiring other 
companies.

The principal competitive factors in our industry include:

•

•

•

•

•

breadth, depth and integration of software;

domain expertise of sales and technical support personnel;

consistent global support;

performance and reliability; and

price.

19

 
Table of Contents

Many of our current and potential competitors have longer-term and more extensive relationships with our existing and potential customers that provide 
them with an advantage in competing for business with those customers. They may be able to devote greater resources to the development and 
improvement of their offerings than we can. These competitors could incorporate additional functionality into their competing products from their wider 
product offerings or leverage their commercial relationships in a manner that uses product bundling or closed technology platforms to discourage 
enterprises from purchasing our applications.

Many existing and potential competitors enjoy competitive advantages over us, such as:

•

•

•

•

•

•

•

•

•

•

larger sales and marketing budgets and resources;

access to larger customer bases, which often provide incumbency advantages;

broader global distribution and presence;

greater resources to make acquisitions;

the ability to bundle competitive offerings with other software and services;

greater brand recognition;

lower labor and development costs;

greater levels of aggregate investment in research and development;

larger and more mature intellectual property portfolios; and

greater financial, technical, management and other resources.

These competitive pressures in our markets or our failure to compete effectively may result in fewer customers, price reductions, licensing of fewer units, 
increased sales and marketing expenses, reduced revenue and gross profits and loss of market share. Any failure to address these factors could harm our 
business.

Because we derive a substantial portion of our revenues from customers in the automotive industry, we are susceptible to factors affecting this industry.

An adverse occurrence, including industry slowdown, recession, political instability, costly or constraining regulations, rapid technological obsolescence, 
excessive inflation, rising interest rates, prolonged disruptions in one or more of our automotive customers’ production schedules, supply disruptions, or 
labor disturbances, that results in a significant decline in the volume of sales in this industry, or in an overall downturn in the business and operations of our 
customers in this industry, could adversely affect our business.

The automotive industry is highly cyclical in nature and sensitive to changes in general economic conditions, consumer preferences and rising interest rates. 
Any weakness in demand in this industry, the insolvency of a manufacturer or suppliers, or constriction of credit markets may cause our automotive 
customers to reduce their amount of software licensed or services requested or request discounts or extended payment terms, any of which may cause 
fluctuations or a decrease in our revenues and timing of cash flows.

Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.

Our quarterly results of operations and our key metrics, including Billings, Adjusted EBITDA and Free Cash Flow, may vary significantly in the future and 
seasonally. Many customers make purchase decisions based on their fiscal year budgets, which often coincide with the calendar year. These seasonal trends 
materially affect our financial results, as license fees become due at the time the license term commences based upon agreed payment terms that customers 
may not adhere to. As a result, new and renewal licenses have been concentrated in the first and fourth quarter of the year, and our cash flows from 
operations have been highest late in the first quarter and early in the second quarter of the succeeding fiscal year. Period-to-period comparisons of our 
operating results may not be meaningful. The results of any one quarter should not be relied upon as an indication of future performance. Our quarterly 
financial results and key metrics may fluctuate as a result of a variety of factors including:

•

•

•

•

seasonal variations in customer purchasing patterns;

our ability to retain and/or increase sales to existing customers at various times;

our ability to attract new customers;

the addition or loss of large customers, including through their acquisitions or industry consolidations;

20

 
Table of Contents

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the timing of recognition of revenues;

the amount and timing of billings;

the amount and timing of operating expenses and capital expenditures;

the length of sales cycles;

significant security breaches, technical difficulties or unforeseen interruptions to the functionality of our software;

the number of new employees added;

the amount and timing of billing for professional services engagements;

the timing and success of new products, features, enhancements or functionalities introduced by us or our competitors;

changes in our pricing policies or those of our competitors;

changes in the competitive dynamics of our industry, including consolidation among competitors;

the timing of expenses related to the development or acquisition of technology;

any future charges for impairment of goodwill from acquired companies;

extraordinary expenses such as litigation or other dispute-related settlement payments;

the impact of new accounting pronouncements; and

general economic conditions.

Billings have historically been highest in the first and fourth quarters of any calendar year and may vary in future quarters. This seasonality or the 
occurrence of any of the factors above may cause our results of operations to vary and our financial statements may not fully reflect the underlying 
performance of our business.

In addition, we may choose to grow our business for the long-term rather than to optimize for profitability or cash flows for a particular shorter-term period. 
If our quarterly results of operations fall below the expectations of investors or securities analysts, the price of our Class A common stock could decline and 
we could face lawsuits, including securities class action suits.

Fluctuations in foreign currency exchange rates could result in declines in our reported revenue and operating results.

As a result of our international activities, we have revenue, expenses, cash, accounts receivable and payment obligations denominated in foreign currencies 
including Euros, British Pounds Sterling, Indian Rupees, Japanese Yen, and Chinese Yuan. Foreign currency risk arises primarily from the net difference 
between non-United States dollar receipts from customers and non-United States dollar operating expenses. The value of foreign currencies against the 
United States dollar can fluctuate significantly, and those fluctuations may occur quickly. We cannot predict the impact of future foreign currency 
fluctuations.

Strengthening of the United States dollar could cause our software to become relatively more expensive to some of our customers leading to decreased 
dollar sales and a reduction in billings and revenue not denominated in United States dollars. Weakening of the United States dollar could result in an 
increase of foreign denominated expenses when reported in United States dollars. A reduction in revenue or an increase in operating expenses due to 
economic volatility or fluctuations in foreign currency exchange rates could have an adverse effect on our financial condition and operating results. Such 
foreign currency exchange rate fluctuations may make it more difficult to detect underlying trends in our business and operating results.

We do not currently engage in currency hedging activities to limit the risk of exchange rate fluctuations. In the future, we may use derivative instruments, 
such as foreign currency forward and option contracts, to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such 
hedging activities may not offset any or more than a portion of the adverse financial effects of unfavorable movements in foreign exchange rates over the 
limited time the hedges are in place, and the cost of those hedging techniques may have a significant negative impact on our operating results. The use of 
hedging instruments may introduce additional risks if we are unable to structure effective hedges with such instruments. If we are not able to successfully 
manage or hedge against the risks associated with currency fluctuations, our financial condition and operating results could be adversely affected.

21

 
Table of Contents

If we fail to attract new or retain existing third-party independent software vendors to participate in the APA, we may not be able to grow the APA 
program.

Our APA program allows our customers to use third-party software that may be unrelated to our software, without the need to enter into additional license 
agreements. The APA program results in increased revenues through revenue sharing and encourages users to stay within the Altair software ecosystem. If 
third-party software providers are unwilling to join the APA on appropriate terms, including agreeing with our revenue share allocations, or if we are unable 
to retain our current APA participants, we may not be able to grow the APA program.

Licensing of our software is dependent, in part, on performance of our distributors and resellers.

We have historically licensed our software primarily through our direct sales force. We have enhanced our units licensing model such that it is able to be 
licensed through a network of distributors and resellers. If these distributors and resellers are unable to successfully adjust their sales methods to support 
our annual recurring licensing model, or become unstable, financially insolvent, or otherwise do not perform as we expect, our revenue growth derived 
from the distributor and reseller channels could be negatively impacted.

If we fail to adapt to technology changes our software may become less marketable, less competitive, or obsolete.

Our success depends in part on our ability to:

•

•

•

•

•

anticipate customer needs;

foresee changes in technology, including to cloud-enabled hardware, software, networking, browser and database technologies;

differentiate our software;

maintain operability of our software with changing technology standards; and

develop or acquire additional or complementary technologies.

We may not be able to develop or market new or enhanced software in a timely manner, which could result in our software becoming less marketable, less 
competitive, or obsolete.

We believe our long-term value as a company will be greater if we focus on growth, which may negatively impact our profitability in the near term.

Part of our business strategy is to focus on our long-term growth. As a result, our profitability may be lower in the near term than it would be if our strategy 
were to maximize short-term profitability. Expanding our research and development efforts, sales and marketing efforts, infrastructure and other such 
investments may not ultimately grow our business or cause higher long-term profitability. If we are ultimately unable to achieve greater profitability at the 
level anticipated by analysts and our stockholders, our Class A common stock price may decline.

Our research and development may not generate revenue or yield expected benefits.

A key element of our strategy is to focus on innovation and invest significantly in research and development to create new software and enhance our 
existing software to address additional applications and serve new markets, both internally and through acquisitions. Research and development projects 
can be technically challenging and expensive, and there may be delays between the time we incur expenses and the time we are able to generate revenue, if 
any. Anticipated customer demand for any software we may develop could decrease after the development cycle has commenced, and we could be unable 
to avoid costs associated with the development of any such software. If we expend a significant amount of resources on research and development and our 
efforts do not lead to the timely introduction or improvement of software that is competitive in our current or future markets, it could harm our business. 
Our development could be limited by government regulations affecting who we can hire, and what markets we can serve.

If we lose our senior executives, we may be unable to achieve our business objectives.

We currently depend on the continued services and performance of James Scapa, our chief executive officer, and other senior executives. Many members of 
this executive team have served the Company for more than 15 years, with Mr. Scapa having served since our founding in 1985. Loss of Mr. Scapa’s 
services or those of other senior executives could delay or prevent the achievement of our business objectives.

Acquisitions may dilute our stockholders, disrupt our core business, divert our resources, or require significant management attention.

Most of our software has been developed internally with acquisitions used to augment our capabilities. We may not effectively identify, evaluate, integrate, 
or use acquired technology or personnel from prior or future acquisitions, or accurately forecast the financial impact of an acquisition, including accounting 
charges.

After the completion of an acquisition, it is possible that our valuation of such acquisition for purchase price allocation purposes may change compared to 
initial expectations and result in unanticipated write-offs or charges, impairment of our goodwill, or a material change to the fair value of the assets and 
liabilities associated with a particular acquisition.

We may pay cash, incur debt, or issue equity securities to fund an acquisition. The payment of cash will decrease available cash. The incurrence of debt 
would likely increase our fixed obligations and could subject us to restrictive covenants or obligations. The issuance of equity securities would likely be 
dilutive to our stockholders. We may also incur unanticipated liabilities as a result of acquiring companies. Future acquisition activity may disrupt our core 
business, divert our resources, or require significant management attention.

International operations expose us to risks inherent in international activities.

Operating in international markets requires significant resources and management attention and subjects us to regulatory, economic and political risks that 
are different from those in the United States. We face risks in doing business internationally that could adversely affect our business, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the need to localize and adapt our software for specific countries, including translation into foreign languages and associated expenses;

foreign exchange risk;

import, export and sanctions restrictions and changes in trade regulation and agreements, including increased government limitations 
concerning sharing technology, end use , and end users and possible foreign government retaliation; 

sales and customer service challenges associated with operating in different countries;

enhanced difficulties of integrating foreign acquisitions;

difficulties in staffing and managing foreign operations and working with foreign partners;

different pricing environments, longer sales cycles, longer accounts receivable payment cycles, and collections issues;

compliance challenges related to the complexity of multiple, conflicting and changing governmental laws and regulations, including the 
Committee on Foreign Investment in the United States (CFIUS), the Foreign Corrupt Practices Act of 1977 (FCPA), employment, ownership, 
trade, tax, privacy and data protection and artificial intelligence laws and regulations;

limitations on enforcement of intellectual property rights;

more restrictive or otherwise unfavorable government regulations affecting U.S. entities;

increased financial accounting and reporting burdens and complexities;

restrictions on the transfer of funds;

withholding and other tax obligations on remittance and other payments made by our subsidiaries; and

unstable regional, economic and political conditions.

Our inability to manage any of these risks successfully, or to comply with these laws and regulations, could reduce our sales, affect our innovation and 
development and harm our business.

If we are unable to match engineers to open positions in our CES business or are otherwise unable to grow our CES business, our revenue could be 
adversely affected.

We operate our client engineering services business by hiring engineers and data scientists for placement at a customer site for specific customer-directed 
assignments and pay them only for the duration of the placement. The success of this business is dependent upon our ability to recruit and retain highly 
skilled, CES staff to meet the requirements of our customers and to maintain ongoing 

23

 
Table of Contents

relationships with these customers. Our CES business constituted approximately 5% of our total revenues for each of the years ended December 31, 2023 
and 2022. Some of our customers satisfy their engineering personnel needs through managed service providers, or MSPs. A significant percentage of the 
engineers we place, either directly or through MSPs, are with U.S.-based customers and are citizens of countries other than the United States. In the event 
these engineers are unable to enter into, or remain in, the United States legally, we may be unable to match engineers with the appropriate skill sets matched 
to open customer positions. If we are unable to attract highly skilled, qualified CES staff because of competitive factors, export controls or immigration 
laws, or otherwise fail to match CES staff to open customer positions, our revenue may be adversely affected.

Our sales to government agencies and their suppliers may be subject to reporting and compliance requirements.

Our customers include agencies of the various governments, including, but not limited to the United States, and their suppliers of products and services. 
These customers may procure our software and services through various governments’ mandated procurement regulations. Because of governmental 
reporting and compliance requirements, we may incur unexpected costs or required supply chain changes and limitations. Government agencies and their 
suppliers may have statutory, contractual or other legal rights to terminate contracts for convenience or due to a default, and any such termination may 
adversely affect our future operating results.

Our revenue mix may vary over time, which could harm our gross margin and operating results.

Our revenue mix may vary over time due to a number of factors, including the mix of term-based licenses and perpetual licenses. Due to the differing 
revenue recognition policies applicable to our term-based licenses, perpetual licenses and professional services, shifts in the mix between subscription and 
perpetual licenses from quarter to quarter, or increases or decreases in revenue derived from our professional engineering services, which have lower gross 
margins than our software services, could produce substantial variation in revenues recognized even if our billings remain consistent. Our gross margins 
and operating results could be impacted by changes in revenue mix and costs, together with other factors, including entry into new markets or growth in 
lower margin markets; entry into markets with different pricing and cost structures; pricing discounts; and increased price competition. Any one of these 
factors or the cumulative effects of certain of these factors may result in significant fluctuations in our gross margin and operating results. This variability 
and unpredictability could result in our failure to meet internal expectations or those of securities analysts or investors for a particular period. If we fail to 
meet or exceed such expectations for these or any other reasons, the market price of our common stock could decline.

If our goodwill or intangible assets become impaired, we may be required to record a significant charge to earnings, which could harm our business.

Under the Generally Accepted Accounting Principles ("GAAP"), we review our intangible assets for impairment when events or changes in circumstances 
indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. As of December 31, 2023 and 2022, 
respectively, we had $458.1 million and $449.0 million of goodwill and $83.6 million and $107.6 million of other intangible assets—net. An adverse 
change in market conditions, particularly if such change has the effect of changing one of our critical assumptions or estimates, could result in a change to 
the estimation of fair value that could result in an impairment charge.

In addition to our software, we source, distribute and sell products, which may expose us to product liability claims, product recalls, and warranty 
claims that could be expensive and harm our business.

We source, distribute and sell products, in part, through certain of our wholly owned subsidiaries. To the extent these products do not perform as expected, 
cause injury or death or are otherwise unsuitable for usage, we may be held liable for claims, including product liability and other claims. A product 
liability claim, any product recalls or an excessive warranty claim, whether arising from defects in design or failure in our supply chains could negatively 
affect our sales or require a change in the design process or our product sourcing, any of which may harm our reputation and business.

Issues in the development and use of AI and machine learning in our offerings, combined with an uncertain regulatory environment, may result in 
reputational harm, liability, or other adverse effects to our business and operating results.

We incorporate machine learning and AI technologies in our offerings and business, and we are making investments in expanding our AI capabilities in our 
products, services, and tools, including ongoing deployment and improvement of existing machine learning and AI technologies. AI technologies are 
complex and rapidly evolving. We face significant competition from other companies as well as an evolving and uncertain regulatory landscape in relation 
to these technologies and “big data.” For example, our machine learning, big data, and AI-related initiatives may give rise to risks related to harmful 
content, accuracy, bias, discrimination, toxicity, intellectual property infringement or misappropriation, defamation, data privacy, and cybersecurity, among 
others. The development, 

24

 
Table of Contents

adoption, introduction, and use of AI technologies in new or existing products may result in new or enhanced governmental or regulatory scrutiny, 
litigation, confidentiality or security risks, ethical concerns, or other complications that could adversely affect our business, reputation, or financial results. 
There are operational risks as well. For example, the algorithms that we or our licensors use may be flawed or may be based on datasets that are biased or 
insufficient. Similarly, any latency, disruption, or failure in our machine learning and AI technologies or infrastructure could result in delays or errors in our 
offerings. 

Uncertainty around new and emerging AI technologies may require additional investment and increase our costs in the development, testing, deployment, 
and maintenance of machine learning models, development of new approaches and processes, and development of appropriate policies, procedures, 
protections and safeguards, which may be costly and could impact our expenses. Our customers or others may rely on or use content generated by AI 
models (e.g., images, text, and language translation) to their detriment, which may expose us to brand or reputational harm, competitive harm, and/or legal 
liability. The development, marketing, and use of AI technologies presents emerging ethical and social issues, and if we enable or offer solutions that draw 
scrutiny or controversy due to their perceived or actual impact on customers, employees, content owners, or on society as a whole, we may experience 
brand or reputational harm, competitive harm, and/or legal liability.

Risks related to our intellectual property

Defects or errors in our software could result in loss of revenue or harm to our reputation.

Our software is complex and, despite extensive testing and quality control, may contain undetected or perceived bugs, defects, errors, or failures. From time 
to time we have found defects or errors in our software and we may discover additional defects in the future. We may not find defects or errors in new or 
enhanced software before release and these defects or errors may not be discovered by us or our customers until after they have used the software. We have 
in the past issued, and may in the future need to issue, corrective releases or updates of our software to remedy bugs, defects and errors or failures. The 
occurrence of any real or perceived bugs, defects, errors, or failures could result in:

•

•

•

•

•

•

•

•

•

lost or delayed market acceptance of our software;

delays in payment to us by customers;

injury to our reputation;

diversion of our resources;

loss of competitive position;

claims by customers for losses sustained by them;

breach of contract claims or related liabilities;

increased customer support expenses or financial concessions; and

increased insurance costs.

Any of these problems could harm our business.

Failure to protect and enforce our proprietary technology and intellectual property rights could substantially harm our business.

The success of our business depends, in part, on our ability to protect and enforce our proprietary technology and intellectual property rights, including our 
trade secrets, patents, trademarks, copyrights, and other intellectual property. We attempt to protect our intellectual property under trade secret, patent, 
trademark, and copyright laws. Despite our efforts, we may not be able to protect our proprietary technology and intellectual property rights, if we are 
unable to enforce our rights or if we do not detect unauthorized use of our intellectual property. Further, the risk of cyberattacks or other privacy or data 
security incidents may be heightened due to common, external attempts to attack our information technology systems and data, using means such as 
phishing. It may be possible for unauthorized third parties to copy our technology and use information that we regard as proprietary to create products and 
services that compete with ours. Provisions in our license agreements protect against unauthorized use, copying, transfer and disclosure of our technology, 
but such provisions may be difficult to enforce or are unenforceable under the laws of certain jurisdictions and countries. The laws of some countries do not 
protect proprietary rights to the same extent as the laws of the United States. Our international activities expose us to unauthorized copying and use of our 
technology and proprietary information.

We primarily rely on our unpatented proprietary technology and trade secrets. Despite our efforts to protect our proprietary technology and trade secrets, 
unauthorized parties may attempt to misappropriate, reverse engineer or otherwise obtain and use them. The 

25

 
Table of Contents

contractual provisions that we enter into with employees, consultants, partners, vendors and customers may not be sufficient to prevent unauthorized use or 
disclosure of our proprietary technology or trade secrets and may not provide an adequate remedy in the event of unauthorized use or disclosure of our 
proprietary technology or trade secrets.

Policing unauthorized use of our technologies, software and intellectual property is difficult, expensive and time-consuming, particularly in countries where 
the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property 
rights may be weak. We may be unable to detect or determine the extent of any unauthorized use or infringement of our software, technologies or 
intellectual property rights.

From time to time, we may need to engage in litigation or other administrative proceedings to protect our intellectual property rights or to defend against 
allegations by third parties that we have infringed or misappropriated their intellectual property rights, including in connection with requests for 
indemnification by our customers who may face such claims. We have been approached and may be approached in the future by certain of our customers to 
indemnify them against third-party intellectual property claims. Litigation and/or any requests for indemnification by our customers could result in 
substantial costs and diversion of resources and could negatively affect our business and revenue. If we are unable to protect and enforce our intellectual 
property rights, our business may be harmed.

Intellectual property disputes could result in significant costs and harm our business.

Intellectual property disputes may occur in the markets in which we compete. Many of our competitors are large companies with significant intellectual 
property portfolios, which they may use to assert claims of infringement, misappropriation or other violations of intellectual property rights against us or 
our customers. Any allegation of infringement, misappropriation or other violation of intellectual property rights by a third-party, even those without merit, 
could cause us to incur substantial costs defending against the claim, could distract our management from our business, and could cause uncertainty among 
our customers or prospective customers, all of which could have an adverse effect on our business or revenue. 

Our agreements may include provisions that require us to indemnify others for losses suffered or incurred as a result of our infringement of a third-party’s 
intellectual property rights infringement, including certain of our employees and customers.

An adverse outcome of a dispute or an indemnity claim may require us to:

•

•

•

•

•

pay substantial damages;

cease licensing our software or portions of it;

develop non-infringing technologies;

acquire or license non-infringing technologies; and

make substantial indemnification payments.

Any of the foregoing or other damages could harm our business, decrease our revenue, increase our expenses or negatively impact our cash flow.

Security breaches, computer malware, computer hacking, cyberattacks and other security incidents could harm our business, reputation, brand and 
operating results.

Security incidents have become more prevalent across industries and may occur on our systems. Security incidents may be caused by, or result in but are 
not limited to, security breaches, computer malware or malicious software, computer hacking, cyberattacks on our information systems, unauthorized 
access to confidential information, denial of service attacks, security system control failures in our own systems or from vendors we use, email phishing, 
software vulnerabilities, social engineering, sabotage and drive-by downloads. Such security incidents, whether intentional or otherwise, may result from 
actions of hackers, criminals, nation states, vendors, employees or customers.

Our company is a highly automated business which relies on our network infrastructure and enterprise applications, third-party providers of cloud-based 
services, internal technology systems and website for development, marketing, operational, support and sales activities. A disruption or failure of these 
systems or in those of our external service providers, in the event of a major storm, earthquake, fire, telecommunications failure, cyberattack, government 
intervention, terrorist attack or other catastrophic event could cause system interruptions, reputational harm, delays in our product development and loss of 
critical data and could materially and adversely affect our ability to operate our business.

We may experience disruptions, data loss, outages and other performance problems on our systems due to service attacks, unauthorized access or other 
security related incidents. Any security breach or loss of system control caused by hacking, which involves efforts to gain unauthorized access to 
information or systems, or to cause intentional malfunctions or loss, modification or corruption of data, software, hardware or other computer equipment 
and the inadvertent transmission of computer malware could harm our business. A cybersecurity incident may occur on our systems, or third-party systems 
upon which we rely, which could disrupt Altair materially in the future.

In addition, some of our software may store and transmit customers’ confidential business information in our facilities and on our equipment, networks, 
corporate systems and in the cloud. Security incidents could expose us to litigation, remediation costs, increased costs for security measures, loss of 
revenue, damage to our reputation and potential liability. Our customer data, corporate systems, and security measures may be compromised due to the 
actions of outside parties, employee error, malfeasance, third-party software, capacity constraints, a combination of these or otherwise and, as a result, an 
unauthorized party may obtain access to our data or our customers’ data. Outside parties may attempt to fraudulently induce our employees to disclose 
sensitive information in order to gain access to our customers’ data or our information. We must continuously examine and modify our security controls 
and business policies to address new threats, the use of new devices and technologies, and these efforts may be costly or distracting.

Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently or may be designed to remain 
dormant until a predetermined event and often are not recognized until launched against a target, we may be unable to anticipate these techniques or 
implement sufficient control measures to defend against these techniques. Though it is difficult to determine what harm may directly result from any 
specific incident or breach, any failure to maintain confidentiality, availability, integrity, performance and reliability of our systems and infrastructure may 
harm our reputation and our ability to retain existing customers and attract new customers. If an actual or perceived security incident occurs, the market 
perception of the effectiveness of our security controls could be harmed, our brand and reputation could be damaged, we could lose customers, and we 
could suffer financial exposure due to such events or in connection with remediation efforts, investigation costs, regulatory fines and changed security 
control, system architecture and system protection measures.

We may lose customers if our software does not work seamlessly with our customers’ existing software.

Our customers may use our software, which in many instances has been designed to seamlessly interface with software from some of our competitors, 
together with their own software and software they license from third parties. If our software ceases to work seamlessly with our customers’ existing 
software applications, we may lose customers.

Many of our customers use our software and services to design and develop their products, which when built and used may expose us to claims.

Many of our customers use our software and services, together with software and services from other third parties and their own resources, to assist in the 
design and development of products intended to be used in a commercial setting. To the extent our customers design or develop a product that results in 
potential liability, including product liability, we may be included in resulting litigation. We may be subject to litigation defense costs or be subject to 
potential judgments or settlement costs for which we may not be fully covered by insurance, which would result in an increase of our expenses.

We also license certain of our software on Altair branded computer hardware, which we acquire from original equipment manufacturers, which we refer to 
as OEMs, exposing us to potential liability for the hardware, such as product liability. To the extent this liability is greater than the warranty and liability 
protection from our OEM, we may incur additional expenses, which may be significant.

If we fail to educate and train our users regarding the use and benefits of our software, we may not generate additional revenue.

Our software is complex and highly technical. We continually educate and train our existing and potential users regarding the depth, breadth, and benefits 
of our software including through classroom and online training. If these users do not receive education and training regarding the use and benefits of our 
software, or the education and training is ineffective, they may not increase their usage of our software. We may incur costs of training directly related to 
this activity prior to generating additional revenue.

We currently open source certain of our software and may open source other software in the future, which could have an adverse effect on our 
revenues and expenses and our use of open source technology could impose limitations on our ability to commercialize our software.

We offer our open matrix language, or OML, source code and a portion of our Altair PBS workload management software in an open source version to 
generate additional usage and broaden user-community development and enhancement of the software. We offer related software and services on a paid 
basis. We believe increased usage of open source software leads to increased purchases of these related paid offerings. We may offer additional software on 
an open source basis in the future. There is no assurance that the incremental revenues from related paid offerings will outweigh the lost revenues and 
incurred expenses attributable to the open sourced software.

We use open source software in some of our software and expect to continue to use open source software in the future. Although we monitor our use of 
open source software to avoid subjecting our software to conditions we do not intend, we may face allegations from others alleging ownership of, or 
seeking to enforce the terms of, an open source license, including by demanding release of the open source software, derivative works, or our proprietary 
source code that was developed using such software. These allegations could also result in litigation. The terms of many open source licenses have not been 
interpreted by United States courts. There is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions 
on our ability to commercialize our software. In such an event, we may be required to seek licenses from third parties to continue commercially offering our 
software, to make our proprietary code generally available in source code form, to re-engineer our software or to discontinue the sale of our software if re-
engineering could not be accomplished on a timely basis, any of which could adversely affect our business and revenue.

The use of open source software subjects us to a number of other risks and challenges. Open source software is subject to further development or 
modification by anyone. Others may develop such software to be competitive with or no longer useful by us. It is also possible for competitors to develop 
their own solutions using open source software, potentially reducing the demand for our software. If we are unable to successfully address these challenges, 
our business and operating results may be adversely affected, and our development costs may increase.

Risks related to legal or regulatory matters

We operate internationally and must comply with employment and related laws in various countries, which may, in turn, result in unexpected expenses.

We are subject to a variety of domestic and foreign employment laws, including those related to safety, discrimination, whistle-blower, privacy and data 
protection, employment of unauthorized or undocumented employees, classification of employees, wages, statutory benefits, and severance payments. Such 
laws are subject to change as a result of judicial decisions or otherwise, and there can be no assurance that we will not be found to have violated any such 
laws in the future. Such violations could lead to the assessment of significant fines against us by federal, state or foreign regulatory authorities or to the 
award of damages claims, including severance payments, against us in judicial or administrative proceedings by employees or former employees, any of 
which would reduce our net income or increase our net loss.

Changes in government trade, immigration or currency policies may harm our business.

We operate our business globally in multiple countries that have policies and regulations relating to trade, immigration and currency, which may change. 
Governments may change their trade policies by withdrawing from negotiations on new trade policies, renegotiating existing trade agreements, imposing 
tariffs or imposing other trade restrictions or barriers. Any such changes may result in:

•

•

•

•

changes in currency exchange rates;

changes in political or economic conditions;

import, sanctions limitations, or export licensing requirements or other restrictions on technology imports and exports;

laws and business practices favoring local companies;

28

 
Table of Contents

•

•

•

•

changes in diplomatic and trade relationships;

modification of existing or implementation of new tariffs;

imposition or increase of trade barriers; or

establishment of new trade or currency restrictions.

Any of these changes, changes in immigration policies, government intervention in currency valuation, geopolitical actions or other domestic or foreign 
government policy changes may adversely impact our ability to sell software and services, hire foreign workers or conduct business in particular countries, 
which could, in turn, harm our revenues and our business. We are headquartered in the United States and may be particularly impacted by changes affecting 
the United States and United States persons wherever located in the world.

We are subject to governmental sanctions, export and import controls that could impair our ability to compete in international markets due to licensing 
requirements and subject us to liability if we are not in compliance with applicable laws.

Our software, services and hardware are subject to sanctions, export control and import laws and regulations. As a company headquartered in the United 
States, we are subject to U.S. regulations wherever we operate in the world, including the International Traffic in Arms Regulations, or ITAR, and Export 
Administration Regulations, or EAR, United States Customs regulations and various economic and trade sanctions regulations administered by the United 
States Treasury Department’s Office of Foreign Assets Control, presenting further risk of unexpected reporting and compliance costs. Compliance with 
these regulations may also prevent and restrict us from deriving revenue from potential customers in certain geographic locations for certain of our 
technologies or preventing employment or business activities.

If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including 
jail time, the possible loss of export or import privileges, loss of government contracts, fines which may be imposed on us and responsible employees or 
managers. Some of these violations are strict liability offenses meaning we can violate the requirements without knowledge of the violation. Obtaining the 
necessary authorizations, including any required license, for a particular sale may be time-consuming, is not guaranteed and may result in the delay or loss 
of sales opportunities. These laws and regulations change on an ongoing basis and we could be affected by third country similar requirements where we do 
business as well as related foreign country retaliation or geopolitical actions. In addition, changes in our software or changes in applicable sanctions, export 
or import regulations may create delays in the introduction and sale of our software in international markets, prevent our customers with international 
operations from deploying our software or, in some cases, prevent the export or import of our software to certain countries, governments or persons 
altogether.

We incorporate encryption technology into portions of our software. Various countries regulate the import of certain encryption technology, including 
through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our software or could limit our 
customers’ ability to implement our software in those countries. Encrypted software and the underlying technology may also be subject to export control 
restrictions. Governmental regulation of encryption technology and regulation of imports or exports of encryption products, or our failure to obtain required 
import or export approval for our software, when applicable, could harm our international sales and adversely affect our revenue. Compliance with 
applicable regulatory requirements regarding the export of our software, including with respect to new releases of our software, may create delays in the 
introduction of our software in international markets, prevent our customers with international operations from deploying our software throughout their 
globally-distributed systems or, in some cases, prevent the export of our software to some countries altogether.

United States export control laws and economic sanction programs prohibit the shipment of certain software and services to countries, governments and 
persons that are subject to United States economic embargoes and trade sanctions, including, but not limited to, Iran, Cuba, North Korea, Syria and the 
Crimea, Donetsk, and Luhansk regions of Ukraine. Any violations of such economic embargoes and trade sanction regulations could have negative 
consequences, including government investigations, civil and criminal penalties and reputational harm. In addition to the embargo absolute prohibitions, 
there are other country programs, sectoral sanctions and export requirements that limit our ability to do business in certain countries and regions such as 
Russia, Venezuela, China and Hong Kong. The prohibitions are continually changing.

Any change in export or import regulations, economic sanctions or related legislation, shift in the enforcement or scope of existing regulations, or change in 
the countries, governments, persons or technologies targeted by such regulations, could result in decreased use of our software by, or in our decreased 
ability to export or license our software to, existing or potential customers with international operations. Any decreased use of our software or limitation on 
our ability to export or license our software could adversely affect our business.

Our business is subject to a wide range of laws and regulations, and our failure to comply with those laws and regulations could harm our business.

Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring and 
enforcing employment and labor laws, workplace safety and environmental laws, privacy and data protection laws, artificial intelligence, financial services 
laws, anti-bribery laws, sanctions, national security, import and export controls, anti-boycott, federal securities laws and tax laws and regulations. In certain 
foreign jurisdictions, these regulatory requirements may be more stringent than those in the United States. These laws and regulations are subject to change 
over time and thus we must continue to monitor and dedicate resources to ensure continued compliance. Non-compliance with applicable regulations or 
requirements could subject us to investigations, sanctions, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, civil 
and criminal penalties or injunctions and jail time for responsible employees and managers. If any governmental sanctions are imposed, or if we do not 
prevail in any possible civil or criminal litigation, our business, operating results, and financial condition could be materially adversely affected. In 
addition, responding to any action will likely result in a significant diversion of management’s attention and resources and an increase in professional fees. 
Enforcement actions and sanctions could harm our business, operating results and financial condition.

If we or any of our employees violate the FCPA, the U.K. Bribery Act or similar anti-bribery laws we could be adversely affected.

The FCPA, the U.K. Bribery Act and similar anti-bribery laws generally prohibit companies and their intermediaries from authorizing, offering or 
providing, directly or indirectly, improper payments or benefits for the purpose of obtaining or retaining business to government officials, political parties 
and private-sector recipients. United States based companies are required to maintain records that accurately and fairly represent their transactions and have 
an adequate system of internal accounting controls. We operate in areas of the world that potentially experience corruption by government officials to some 
degree and, in certain circumstances, compliance with anti-bribery laws may conflict with local customs and practices. We cannot assure that our 
employees, resellers or distributors will not engage in prohibited conduct. If we are found to be in violation of the FCPA, the U.K. Bribery Act or other 
anti-bribery laws, we could suffer criminal or civil penalties or other sanctions.

We have significant deferred tax assets primarily in the United States, which we may not use in future taxable periods.

As of December 31, 2023 and 2022, we had gross deferred tax assets, or DTAs, of $208.5 million and $179.8 million, respectively, primarily related to 
capitalized research and development expenses, net operating loss carryforwards, tax credits and share-based compensation. We are entitled to a United 
States federal tax deduction when non-qualified stock options, or NSOs, are exercised. For the 2023 tax year, we recorded a net increase in the valuation 
allowance of $29.9 million for the gross DTAs. Our ability to utilize any net operating losses or tax credits may be limited under provisions of the Internal 
Revenue Code of 1986, as amended, or the Code, if we undergo an ownership change (generally defined as a greater than 50-percentage-point cumulative 
change, by value, in the equity ownership of certain stockholders over a rolling three-year period). We also inherited net operating losses, or NOLs, from 
the acquisitions of Univa and RapidMiner, which are subject to specific limitations on usage. We may or may not be able to realize the benefits of the 
acquired NOLs due to a number of factors, including those enumerated above. We may also be unable to realize our tax credit carryforwards prior to their 
expiration.

Our NOLs may also be impaired under state laws. In addition, under the 2017 Tax Cuts and Jobs Act, or Tax Act, tax losses generated in taxable years 
beginning after December 31, 2017 may be utilized to offset no more than 80% of taxable income annually. There is also a risk that due to regulatory 
changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future 
income tax liabilities. 

For tax years beginning on or after January 1, 2022, the Tax Act eliminates the option to currently deduct certain qualifying research and development 
expenses and requires taxpayers to capitalize and amortize such expenses over five years for research activities performed in the United States and 15 years 
for research activities performed outside the United States pursuant to Section 174 of the Code. Although Congress is considering legislation that would 
repeal or defer this capitalization and amortization requirement, it is not certain that this provision will be repealed or otherwise modified. If the 
requirement is not repealed or replaced, it will increase our U.S. federal and state cash taxes and reduce cash flows in fiscal year 2024 and future years.

If our global tax methodology is challenged, our tax expense may increase.

As a global business headquartered in the United States, we are required to pay tax in a number of different countries, exposing us to transfer pricing and 
other adjustments. Transfer pricing refers to the methodology of allocating revenue and expenses for tax purposes to particular countries. Taxing authorities 
may challenge our transfer pricing methodology, which if successful could increase our 

30

 
Table of Contents

professional expenses and result in one-time or recurring tax charges, a higher worldwide effective tax rate, reduced cash flows, and lower overall 
profitability of our operations.

Our tax expense could be impacted depending on the applicability of withholding and other taxes including taxes on software licenses and related 
intercompany transactions under the tax laws of jurisdictions in which we have business operations. Our future income taxes may fluctuate if there is a 
change in the mix of income in the applicable tax jurisdictions in which we operate. We are subject to review and audit by the United States and other 
taxing authorities. Any review or audit could increase our professional expenses and, if determined adversely, could result in unexpected costs.

Sales and use, value-added and similar tax laws and rates vary by jurisdiction. Any of these jurisdictions may assert that such taxes are applicable, which 
could result in tax assessments, penalties and interest.

We could be subject to adverse changes in tax laws, regulations and interpretations or challenges to our tax positions.

We are subject to tax laws and regulations of the U.S. federal, state and local governments as well as various non-U.S. jurisdictions. Potential changes in 
existing tax laws, including future regulatory guidance, may impact our effective income tax rate and tax payments. There can be no assurance that changes 
in tax laws or regulations, both within the U.S. and the other jurisdictions in which we operate, will not materially and adversely affect our effective income 
tax rate, tax payments, financial condition and results of operations. Similarly, changes in tax laws and regulations that impact our customers and 
counterparties or the economy generally may also impact our financial condition and results of operations.

In addition, tax laws and regulations are complex and subject to varying interpretations, and any significant failure to comply with applicable tax laws and 
regulations in all relevant jurisdictions could give rise to substantial penalties and liabilities. Any changes in enacted tax laws, rules or regulatory or judicial 
interpretations; any adverse outcome in connection with tax audits in any jurisdiction; or any change in the pronouncements relating to accounting for 
income taxes could materially and adversely impact our effective income tax rate, tax payments, financial condition and results of operations.

Our business may collect personal information and is subject to data protection laws.

Companies that collect or process personal information may be regulated by data protection laws adopted by the United States, various states including 
California, Nevada, Virginia, Colorado, Connecticut and Utah, and foreign jurisdictions, including the European Union, the United Kingdom, Canada, 
Brazil and China. The European Union General Data Protection Regulation and implementing legislation adopted by member states of the European 
Economic Area (“GDPR”) in 2018, and the United Kingdom Data Protection Act 2018 (the “UK GDPR”) frequently serve as a model for other countries. 
All of these data protection laws regulate the collection, use, storage, disclosure and security of personal information, such as names, email addresses, 
Internet Protocol addresses and other online identifiers, business contact data, and customer profiles, that may be used to identify or locate an individual, 
including customers, employees, business contracts, website visitors and users of mobile apps.

The legal, financial and business impact of these data protection laws and regulations is far-reaching and may require us to modify our data processing 
practices and policies and incur substantial costs and expenses in an effort to comply. We may be required to implement privacy and security policies, 
permit individuals to access and correct their own personal information that is collected, stored or maintained by us, and require us to transfer, delete or 
return their personal information. It may also be necessary for us to obtain individuals’ affirmative consent to collect, use or disclose their personal 
information for certain purposes. Governmental authorities could prohibit any personal information collected in a country from being transferred or 
disclosed outside of that country or condition such transfer or disclosure on compliance with specific requirements or written agreements. We also may find 
it necessary or desirable to join industry or other self-regulatory bodies or other information security, or data protection, related organizations that require 
compliance with their rules pertaining to information security and data protection. We may agree to be bound by additional contractual obligations relating 
to our collection, use and disclosure of personal, financial and other data. Our failure to comply with these data protection laws may result in governmental 
actions, fines and non-monetary penalties, or civil actions, and reputational damage, which may harm our business.

Proposed or new legislation and regulations could significantly affect our business. 

The GDPR, which became effective in May 2018, applies to all our business conducted in the European Economic Area (the “EEA”).  In the post-Brexit 
area, our business in the United Kingdom is regulated by the U.K. GDPR. New data protection laws have just come into effect in Brazil and China, and a 
new Indian law has been passed in 2023 and is expected to come into effect soon. In the US, state-specific data protection laws are in effect in California, 
Virginia, Colorado, Nevada, Connecticut and Utah, and new data protection laws will become effective during 2024 in the states of Texas, Florida, Oregon, 
and Montana. Similar laws will become effective in the next two years in another five states and are pending in many more states. These data protection 
laws and regulations impose many obligations, and we will need to continue dedicating financial resources and management time to compliance and 
training in the coming years. Data protection laws, for example, may require, that regulated entities expand disclosures about how personal data is used, 
mechanisms for obtaining consent from data subjects, controls for data subjects with respect to their personal data (including by enabling them to exercise 
rights to erasure and data portability), limitations on retention of personal data and mandatory data breach notifications. There are also restrictions on data 
transfers and the security of the personal data, frequently with substantial fines and penalties associated with violations. The GDPR, for example, provides 
that supervisory authorities in the European Union may impose administrative fines for certain infringements of the GDPR (up to EUR 20,000,000, or 4% 
of an undertaking’s total, worldwide, annual revenue, whichever is higher). Individuals who sustain damages because a regulated entity fails to comply with 
the GDPR have the right to seek compensation from such entity directly. Compliance with data protection laws, the rapid pace of adopting new and 
amended laws, and necessary monitoring and training will require significant expenditure of resources on an ongoing basis, and there can be no assurance 
that the measures we have taken for the purposes of compliance will be successful in preventing violations of such laws, cyberattacks, governmental actions 
or civil proceedings. Given the potential fines, liabilities and damage to our reputation in the event of an actual or perceived violation of data protection 
laws, any violation may have an adverse effect on our business and operations.

As the number of jurisdictions with data privacy regulations increase and our global footprint expands, we anticipate that it will be necessary for us to 
increase the amount we expend on compliance and training in this area.

Risks related to ownership of our Class A common stock

An active public trading market for our Class A common stock may not be sustained.

Our Class A common stock is listed on the Nasdaq Global Select Market under the symbol “ALTR.” However, we cannot assure you that an active trading 
market will be sustained. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you 
consider reasonable. The lack of an active market may also reduce the price of shares of Class A common stock. An inactive market may impair our ability 
to raise capital by selling shares and our ability to use our capital stock to acquire other companies or technologies. We cannot predict the prices at which 
our Class A common stock will trade.

The market price of our Class A common stock can be volatile.

The market price of our Class A common stock has and may continue to fluctuate from time to time. Our market price may continue to fluctuate 
substantially depending on a number of factors, many of which are beyond our control and may not be related to our operating performance. These 
fluctuations could cause you to lose all or part of your investment in our Class A common stock, since you might not be able to sell your shares at or above 
the price you paid for our Class A common stock. Factors that could cause fluctuations in the market price of our Class A common stock include the 
following:

•

•

•

•

•

•

•

price and volume fluctuations in the overall stock market from time to time, including as a result of trends in the economy as a whole;

volatility in the market prices and trading volumes of technology stocks;

changes in operating performance and stock market valuations of other technology companies generally, or those in our industries in 
particular;

the volume of shares of our Class A common stock available for public sale;

sales of shares of our Class A common stock;

additional shares of our Class A common stock being sold into the market by our existing stockholders, or the anticipation of such sales, 
including sales of our Class A common stock upon exercise of outstanding options or upon conversion of our Class B common stock into 
shares of Class A common stock;

failure of financial analysts to maintain coverage of us, changes in financial estimates by any analysts who follow our company, or our failure 
to meet these estimates or the expectations of investors;

the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

announcements by us or our competitors of new software or new or terminated significant contracts, commercial relationships or capital 
commitments;

public analyst or investor reaction to our press releases, other public announcements and filings with the SEC;

rumors and market speculation involving us or other companies in our industry;

actual or anticipated changes or fluctuations in our operating results;

actual or anticipated developments in our business, our customers’ businesses, or our competitors’ businesses or the competitive landscape 
generally;

litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;

developments or disputes concerning our intellectual property or our solutions, or third-party proprietary rights;

announced or completed acquisitions of businesses or technologies by us or our competitors;

new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

changes in accounting standards, policies, guidelines, interpretations or principles;

any major changes in our management or our board of directors;

general economic conditions and slow or negative growth of our markets; and

other events or factors, including those resulting from major weather events, war, potential global health issues, incidents of terrorism or 
responses to these events.

In addition, the stock market in general, and the market for technology companies in particular, have experienced extreme price and volume fluctuations 
that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may affect the 
market price of our Class A common stock, regardless of our actual operating performance. In the past, following periods of volatility in the overall market 
and the market prices of a particular company’s securities, securities class action litigation has often been instituted against that company. We may become 
the target of this type of litigation in the future. Securities litigation, if instituted against us, could result in substantial costs and divert our management’s 
attention and resources from our business.

We do not intend to pay dividends in the foreseeable future. As a result, your ability to achieve a return on your investment will depend on appreciation 
in the price of our Class A common stock.

We have never declared or paid any cash dividends on our Class A common stock. We currently intend to retain all available funds and any future earnings 
for use in the operation of our business and do not anticipate paying any dividends on our Class A common stock in the foreseeable future. Any 
determination to pay dividends in the future will be at the discretion of our board of directors. Consequently, your only opportunity to achieve a return on 
your investment in our company will be if the market price of our Class A common stock appreciates and you sell your shares at a profit. There is no 
guarantee that the price of our Class A common stock that will prevail in the market will ever exceed the price that you paid.

If we fail to maintain effective internal controls, we may not be able to report financial results accurately or on a timely basis, or to detect fraud, which 
could have a material adverse effect on our business or share price.

Effective internal controls are necessary for us to provide reasonable assurance with respect to our financial reports and to effectively prevent financial 
fraud. Pursuant to the Sarbanes-Oxley Act of 2002, or SOX, we are required to periodically evaluate the effectiveness of the design and operation of our 
internal controls. Internal controls over financial reporting may not prevent or detect misstatements because of inherent limitations, including the possibility 
of human error or collusion, the circumvention or overriding of controls, or fraud. If we fail to maintain an effective system of internal controls, our 
business and operating results could be harmed, and we could fail to meet our reporting obligations, which could have a material adverse effect on our 
business and our share price.

33

 
Table of Contents

As a public company, we are required to maintain internal controls over financial reporting and to report any material weaknesses in such internal controls. 
Section 404 of SOX requires annual management assessments of the effectiveness of our internal controls over financial reporting. We have designed, 
implemented and tested the internal control over financial reporting required to comply with this obligation, which was and is time consuming, costly, and 
complicated. A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a 
reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. We 
cannot assure investors that we will not have material weaknesses in the future. If we identify material weaknesses in our internal control over financial 
reporting in the future or if we are unable to successfully remediate the identified material weaknesses or, if we are unable to comply with the requirements 
of Section 404 in a timely manner or assert that our internal control over financial reporting is effective, investors may lose confidence in the accuracy and 
completeness of our financial reports and the market price of our Class A common stock could be negatively affected, and we could become subject to 
investigations by the stock exchange on which our securities are listed, the SEC, or other regulatory authorities, which could require additional financial 
and management resources.

If financial or industry analysts do not publish research or reports about our business or if they issue inaccurate or unfavorable commentary or 
downgrade our Class A common stock, our stock price and trading volume could decline.

The trading market for our Class A common stock may be influenced by the research and reports that industry or financial analysts publish about us or our 
business. We do not control these analysts, or the content and opinions included in their reports. We may be slow to attract research coverage, and the 
analysts who publish information about our Class A common stock still have relatively little experience with our company, which could affect their ability 
to accurately forecast our results and make it more likely that we fail to meet their estimates. If any of the analysts who cover us issue an inaccurate or 
unfavorable opinion regarding our stock price, our stock price would likely decline. In addition, the stock prices of many companies in the technology 
industry have declined significantly after those companies have failed to meet, or often times failed to exceed, the financial guidance publicly announced by 
the companies or the expectations of analysts. If our financial results fail to meet, or fail to exceed, our announced guidance or the expectations of analysts 
or public investors, analysts could downgrade our Class A common stock or publish unfavorable research about us. If one or more of these analysts cease 
coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock 
price or trading volume to decline.

Future sales of substantial amounts of our Class A common stock may cause our stock price to decline.

Future sales of a substantial number of shares of our Class A common stock, particularly sales by our directors, executive officers and significant 
stockholders could adversely affect the market price of our Class A common stock and may make it more difficult to sell Class A common stock at a time 
and price that you deem appropriate. As of December 31, 2023, we had an aggregate of 55,239,516 shares of Class A common stock and 26,814,574 shares 
of Class B common stock outstanding.

Shares held by directors, executive officers and other affiliates are subject to volume limitations under Rule 144 under the Securities Act and various 
vesting agreements. 

We have registered the offer and sale of an aggregate of approximately 29,939,594 shares of Class A common stock that have been issued or reserved for 
future issuance under our equity compensation plans on a Form S-8 registration statement. These shares can be freely sold in the public market upon 
issuance, unless they are held by “affiliates,” as that term is defined in Rule 144 of the Securities Act. Additionally, the number of shares of Class A 
common stock available for grant and issuance under our 2017 Equity Incentive Plan is subject to an automatic annual increase on January 1 of each year 
beginning in 2018 by an amount equal to the lesser of (i) 3% of the number of shares of all classes of our common stock outstanding on December 31 of the 
preceding calendar year or (ii) a lesser number of shares of Class A common stock determined by our board of directors. We also intend to register the offer 
and sale of any shares of Class A common stock resulting from such increases. If the holders of these shares choose to sell a large number of shares, they 
could adversely affect the market price for our Class A common stock.

We may also issue shares of our Class A common stock or securities convertible into shares of our Class A common stock from time to time in connection 
with a financing, acquisition, investment or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and cause the 
trading price of our Class A common stock to decline.

The dual class structure of our common stock has the effect of concentrating voting control with certain stockholders who hold shares of our Class B 
common stock, including our founders, who hold in aggregate approximately 83% of the voting power of our capital stock. This will limit or preclude 
your ability to influence corporate matters, including the election of directors, amendments of our organizational documents, and any merger, 
consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval.

Our Class B common stock has ten votes per share, and our Class A common stock has one vote per share. Our Class B stockholders, including our 
founders, hold, in aggregate approximately 83% of the voting power of our capital stock. The ten-to-one voting ratio between our Class B and Class A 
common stock, results in the holders of our Class B common stock collectively controlling a majority of the combined voting power of our common stock 
and therefore being able to control all matters submitted to our stockholders for approval until 2029, or upon the occurrence of a triggering event at which 
time all shares of our Class B common stock will automatically convert into shares of our Class A common stock, or on an earlier date, each as set forth in 
our Delaware certificate of incorporation.

This concentrated control will limit or preclude your ability to influence corporate matters for the foreseeable future, including the election of directors, 
amendments of our organizational documents, and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate 
transaction requiring stockholder approval. In addition, this may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that 
you may feel are in your best interest as one of our stockholders.

Future transfers by holders of our Class B common stock will generally result in those shares converting to Class A common stock, subject to the specific 
exceptions set forth in our Delaware certificate of incorporation, such as certain transfers effected for estate planning purposes and between or among our 
founders. The conversion of Class B common stock to Class A common stock will have the effect, over time, of increasing the relative voting power of 
those holders of Class B common stock who retain their shares in the long-term.

Certain provisions in our charter documents and Delaware law could prevent an acquisition of our company, limit attempts by our stockholders to 
replace or remove members of our board of directors or current management and may adversely affect the market price of our Class A common stock.

Our Delaware certificate of incorporation and bylaws contain provisions that could delay or prevent a change in control of our company that stockholders 
may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions may also 
prevent or delay attempts by stockholders to replace or remove our current management or members of our board of directors. These provisions include:

•

•

•

•

•

•

•

providing for a dual class common stock structure for 12 years following the completion of our IPO;

providing for a classified board of directors with staggered three-year terms, which could delay the ability of stockholders to change the 
membership of a majority of our board of directors;

authorizing our board of directors to issue shares of preferred stock and to determine the price and other terms of those shares, including 
preferences and voting rights, without stockholder approval;

the requirement that a special meeting of stockholders may be called only by the chairman of our board of directors, our chief executive 
officer, our president, or a majority vote of our board of directors, which could delay the ability of our stockholders to force consideration of 
a proposal or to take action, including the removal of directors;

requiring the affirmative vote of holders of at least 66  2 / 3 % of the voting power of all of the then outstanding shares of the voting stock, 
voting together as a single class, to adopt, amend, or repeal provisions of (i) our certificate of incorporation relating to the issuance of 
preferred stock without stockholder approval, voting rights of our Class A common stock and our Class B common stock, and management 
of our business, and (ii) our bylaws relating to the ability of stockholders to call a special meeting and amending our bylaws in their entirety, 
which may inhibit the ability of an acquirer to effect such amendments to facilitate an unsolicited takeover attempt;

the ability of our board of directors, by majority vote, to amend our bylaws, which may allow our board of directors to take additional actions 
to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend our bylaws to facilitate an unsolicited takeover attempt; and

requiring advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or to propose 
matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of 
proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

35

 
Table of Contents

In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large 
stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

These and other provisions in our certificate of incorporation, our bylaws and under Delaware law could discourage potential takeover attempts, reduce the 
price that investors might be willing to pay for shares of our Class A common stock in the future and result in the market price being lower than it would be 
without these provisions.

Risks Related to Our Indebtedness 

Our Convertible Senior Notes maturing on June 1, 2024, and our Convertible Notes due in 2027, or collectively the Convertible Notes, are effectively 
subordinated to our secured debt and any liabilities of our subsidiaries.

The Convertible Senior Notes maturing on June 1, 2024 (the "2024 Notes") and the Convertible Senior Notes due in 2027 (the "2027 Notes", collectively 
with the 2024 Notes the "Convertible Notes") rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment 
to the Convertible Notes; equal in right of payment to any of our liabilities that are not so subordinated; effectively junior in right of payment to any of our 
secured indebtedness (including all amounts outstanding under our revolving credit facility) to the extent of the value of the assets securing such 
indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. In the event of our bankruptcy, 
liquidation, reorganization or other winding up, our assets that secure debt ranking senior or equal in right of payment to the Convertible Notes (including 
all amounts outstanding under our revolving credit facility) will be available to pay obligations on the Convertible Notes only after the secured debt has 
been repaid in full from these assets, and the assets of our subsidiaries will be available to pay obligations on the Convertible Notes only after all claims 
senior to the Convertible Notes have been repaid in full. There may not be sufficient assets remaining to pay amounts due on any or all of the Convertible 
Notes then outstanding. The indenture governing the Convertible Notes will not prohibit us from incurring additional senior debt or secured debt, nor does 
it prohibit any of our subsidiaries from incurring additional liabilities.

The Convertible Notes are our obligations only and a substantial portion of our operations are conducted through, and a substantial portion of our 
consolidated assets are held by, our subsidiaries.

The Convertible Notes are our obligations exclusively and are not guaranteed by any of our operating subsidiaries. A substantial portion of our operations is 
conducted through, and a substantial portion of our consolidated assets is held by, our subsidiaries. Accordingly, our ability to service our debt, including 
the Convertible Notes, depends in part on the results of operations of our subsidiaries and upon the ability of such subsidiaries to provide us with cash, 
whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the Convertible Notes. Our subsidiaries are separate 
and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the Convertible Notes or to make any funds available for 
that purpose. In addition, dividends, loans or other distributions to us from such subsidiaries may be subject to contractual and other restrictions and are 
subject to other business considerations.

Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our future indebtedness, including the amounts payable under 
our revolving credit facility and the Convertible Notes, depends on our future performance, which is subject to economic, financial, competitive and other 
factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make 
necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, 
restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will 
depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities 
on desirable terms, which could result in a default on our debt obligations. In addition, the credit agreement governing our revolving credit facility contains, 
and any of our future debt agreements may contain restrictive covenants that may prohibit us from adopting any of these alternatives. Our failure to comply 
with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of our debt.

36

 
Table of Contents

We may still incur substantially more debt or take other actions which would intensify the risks discussed above.

We and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of 
which may be secured debt. We will not be restricted under the terms of the indenture governing the Convertible Notes from incurring additional debt, 
securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the indenture governing the 
Convertible Notes that could have the effect of diminishing our ability to make payments on the Convertible Notes when due. Our existing revolving credit 
facility restricts our ability to incur additional indebtedness, including secured indebtedness, but if those restrictions are waived, or the facility matures or is 
repaid, we may not be subject to such restrictions under the terms of any subsequent indebtedness.

We may not have the ability to raise the funds necessary to settle conversions of the Convertible Notes in cash or to repurchase the Convertible Notes 
upon a fundamental change, and our current debt contains, and our future debt may contain, limitations on our ability to pay cash upon conversion or 
repurchase of the Convertible Notes.

Holders of the Convertible Notes will have the right to require us to repurchase their Convertible Notes upon the occurrence of a fundamental change at a 
defined repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. In 
addition, upon conversion of the Convertible Notes, unless with respect to our 2027 Notes, we elect to deliver solely shares of our Class A common stock 
to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the 
Convertible Notes being converted. However, we may not have enough available cash or be able to obtain financing on favorable terms or at all at the time 
we are required to make repurchases of Convertible Notes surrendered therefor or Convertible Notes being converted.

In addition, our ability to repurchase the Convertible Notes or to pay cash upon conversions of the Convertible Notes may be limited by law, by regulatory 
authority or by agreements governing our indebtedness including our existing revolving credit facility. Our failure to repurchase Convertible Notes at a time 
when the repurchase is required by the indenture or to pay any cash payable on future conversions of the Convertible Notes as required by the indenture 
would constitute a default under the indenture. A default under the indenture or the occurrence of a fundamental change itself would likely also lead to a 
default under our revolving credit facility and may lead to a default under agreements governing our future indebtedness. If the repayment of the related 
indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase 
the Convertible Notes or make cash payments upon conversions thereof.

Our revolving credit facility limits our ability to pay any cash amount upon the conversion or repurchase of the Convertible Notes.

Our existing revolving credit facility prohibits us from making any cash payments on the conversion or repurchase of the Convertible Notes if a default 
under such credit facility exists or would be created thereby. In addition, our ability to make cash payments on the conversion or repurchase of the 
Convertible Notes will be limited to the extent we do not satisfy certain financial covenant tests after giving effect to such payments. Any new credit 
facility that we may enter into may have similar restrictions. Our failure to make cash payments upon the conversion or repurchase of the Convertible Notes 
as required under the terms of the Convertible Notes would permit holders of the Convertible Notes to accelerate our obligations under the Convertible 
Notes.

Our loan agreements contain operating and financial covenants that may restrict our business and financing activities.

Our credit agreement, as amended, provides for an initial aggregate commitment amount of $200 million, with a sublimit for the issuance of letters of credit 
of up to $5.0 million and a sublimit for swing line loans of up to $5.0 million and matures on December 31, 2025 (the “2019 Amended Credit Agreement”). 
Our 2019 Amended Credit Agreement is unconditionally guaranteed by us and all existing and subsequently acquired controlled domestic subsidiaries. It is 
also collateralized by a first priority, perfected security interest in, and mortgages on, substantially all of our tangible assets. The 2019 Amended Credit 
Agreement contains operating financial restrictions and covenants, including liens, limitations on indebtedness, fundamental changes, limitations on 
guarantees, limitations on sales of assets and sales of receivables, dividends, distributions and other restricted payments, transactions with affiliates, 
prepayment of indebtedness and limitations on loans and investments in each case subject to certain exceptions. In addition, the 2019 Amended Credit 
Agreement contains financial covenants relating to maintaining a maximum senior secured leverage ratio of 3.0 to 1.0, as defined in the 2019 Amended 
Credit Agreement. The restrictions and covenants in the 2019 Amended Credit Agreement, as well as those contained in any future debt financing 
agreements that we may enter into, may restrict our ability to finance our operations and engage in, expand or otherwise pursue our business activities and 
strategies. Our ability to comply with these covenants and restrictions may be affected by events beyond our control, and breaches of these covenants and 
restrictions could result in a default under the loan agreement and any future financing agreements that we may enter into.

Table of Contents

Provisions relating to the conversion of our Convertible Notes may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the 2027 Notes is triggered, holders of the 2027 Notes will be entitled to convert the 2027 Notes at any 
time during specified periods at their option. If one or more holders elect to convert their 2027 Notes, unless we elect to satisfy our conversion obligation 
by delivering solely shares of our Class A common stock (other than paying cash in lieu of delivering any fractional share) with respect to the 2027 Notes, 
we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In 
addition, even if holders of the 2027 Notes do not elect to convert their 2027 Notes, we could be required under applicable accounting rules to reclassify all 
or a portion of the outstanding principal of the 2027 Notes as a current rather than long-term liability, which would result in a material reduction of our net 
working capital. We have elected to settle the 2024 Notes par value in cash, which we currently expect to fund from our available cash, and will settle the 
premium in shares of our Class A common stock. Our business may not continue to generate cash flow from operations in the future sufficient to satisfy our 
obligations under our existing indebtedness, and any future indebtedness we may incur, and to make necessary capital expenditures. If we are unable to 
generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling 
assets, refinancing, or obtaining additional equity capital on terms that may be onerous or highly dilutive.

Provisions in the indenture governing the Convertible Notes may deter or prevent a business combination that may be favorable to you.

As stated above, if a fundamental change occurs prior to the maturity date, holders of the Convertible Notes will have the right, at their option, to require us 
to repurchase all or a portion of their Convertible Notes. In addition, if a make-whole fundamental change occurs prior to the maturity date, we will, in 
some cases, be required to increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such make-whole 
fundamental change. Furthermore, the indenture governing the Convertible Notes will prohibit us from engaging in certain mergers or acquisitions unless, 
among other things, the surviving entity assumes our obligations under the Convertible Notes. These and other provisions in the indenture governing the 
Convertible Notes could deter or prevent a third-party from acquiring us even when the acquisition may be favorable to you.

Transactions relating to the Convertible Notes may affect the value of our Class A common stock.

As noted above, we have elected to settle the 2024 Notes par value in cash and will settle the premium in shares of our Class A common stock; the 
settlement of the premium in shares will have a dilutive impact on the ownership interests of existing stockholders. The conversion of some or all of the 
2027 Notes would dilute the ownership interests of existing stockholders to the extent we satisfy our conversion obligation by delivering shares of our 
Class A common stock upon any conversion of the 2027 Notes. If holders of our 2027 Notes elect to convert their notes, we may settle our conversion 
obligation by delivering to them a significant number of shares of our Class A common stock, which would cause dilution to our existing stockholders.

General Risk Factors

If we are unable to attract and retain key personnel, we may be unable to achieve our business objectives.

Our business is dependent on our ability to attract and retain highly skilled software engineers, data scientists, salespeople, and support teams. There is 
significant industry competition for these individuals. We have many employees whose equity awards in our company are fully vested and may increase 
their personal wealth, which could affect their decision to remain with the Company. Failure to attract or retain key personnel could delay or prevent the 
achievement of our business objectives.

We may require additional capital to support our business, which may not be available on acceptable terms.

We expect to continue to make investments in our business, which may require us to raise additional funds. We may raise these funds through either equity 
or debt financings. Issuances of equity or convertible debt securities may significantly dilute stockholders and any new equity securities could have rights, 
preferences and privileges superior to those holders of our Class A common stock. In addition to the restrictions under our current credit agreement, any 
future debt financings could contain restrictive covenants relating to our capital raising activities and other financial and operational matters, which may 
make it more difficult for us to obtain additional capital, manage our business and pursue business opportunities, including potential acquisitions.

We may not be able to obtain additional financing on terms favorable to us. If we are unable to obtain adequate financing or financing on terms satisfactory 
to us when we require it, our ability to continue to support our growth, develop new software or add capabilities and enhancements to our existing software 
and respond to business challenges could be significantly impaired, and our business may be adversely affected.

38

 
Table of Contents

The estimates of market opportunity and forecasts of market growth included in our periodic reports or other public disclosures may prove to be 
inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

Market opportunity estimates and growth forecasts included in our periodic reports or other public disclosures, including those we have generated 
ourselves, are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Even if the market in which 
we compete meets the size estimates and growth forecasted in our periodic reports or other public disclosures, our business could fail to grow for a variety 
of reasons, which would adversely affect our results of operations.

Adverse global conditions, including economic uncertainty, may negatively impact our financial results.

Global conditions, dislocations in the financial markets, any negative financial impacts affecting United States corporations operating on a global basis as a 
result of tax reform or changes to existing trade agreements or tax conventions, inflation, or rising interest rates, could adversely impact our business in a 
number of ways, including longer sales cycles, lower prices for our software license fees, reduced licensing renewals, customer disruption or foreign 
currency fluctuations.

In addition, the global macroeconomic environment could be negatively affected by, among other things, instability in global economic markets, increased 
U.S. trade tariffs and trade disputes with other countries, instability in the global credit markets, supply chain weaknesses, instability in the geopolitical 
environment as a result of geopolitical tensions and conflicts, ongoing efforts to defend U.S. national security, and foreign governmental debt concerns. 
Such challenges have caused, and may continue to cause, uncertainty and instability in local economies and in global financial markets.

During challenging economic times our customers may be unable or unwilling to make timely payments to us, which could cause us to incur increased bad 
debt expenses. Our customers may unilaterally extend the payment terms of our invoices, adversely affecting our short-term or long-term cash flows.

Business interruptions could adversely affect our business.

Our operations and our customers are vulnerable to interruptions by fire, flood, earthquake, power loss, telecommunications failure, terrorist attacks, wars, 
environmental events and climate change, and other events beyond our control. A catastrophic event that results in the destruction of any of our critical 
business or information technology systems could severely affect our ability to conduct normal business operations, including system interruptions, 
reputational harm, delays in our software development, breaches of data security and loss of critical data.

We rely on our network and third-party infrastructure and applications, internal technology systems, and our websites for our development, marketing, 
operational support, hosted services and sales activities. If these systems were to fail or be negatively impacted as a result of a natural disaster or other 
event, our ability to deliver software and training to our customers could be impaired.

In addition, the occurrence of an epidemic or a pandemic, such as the COVID-19 pandemic, may have an adverse effect on our operating results. The 
impacts of a potential epidemic or pandemic, or a resurgence of COVID-19, could pose the risk that we or our employees, suppliers, customers and others 
may be restricted or prevented from conducting business activities for indefinite or intermittent periods of time, including as a result of employee health and 
safety concerns, shutdowns, shelter in place orders, travel restrictions and other actions and restrictions that may be prudent or required by governmental 
authorities. The extent to which epidemics and pandemics impact our financial condition or results of operations will depend on many factors outside of our 
control and whether there is a material impact on the businesses or productivity of our customers, employees, suppliers and other partners. 

Our business interruption insurance may not be sufficient to compensate us fully for losses or damages that may occur as a result of these events, if at all.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States.

GAAP are subject to interpretation by the Financial Accounting Standards Board, or FASB, the United States Securities and Exchange Commission, or the 
SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a 
significant effect on our reported financial results for periods prior and subsequent to such change. The adoption of new standards may require 
enhancements or changes in our systems and will continue to require significant time and effort of our financial management team.

39

 
Table of Contents

We cannot predict the impact of all of the future changes to accounting principles or our accounting policies on our consolidated financial statements going 
forward, which could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the 
announcement of the change. In addition, if we were to change our critical accounting estimates, including those related to the recognition of license 
revenue and other revenue sources, our operating results could be significantly affected.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

We believe cybersecurity is a necessity for operating our business. As a global leader in computational science and artificial intelligence, we face many 
cybersecurity threats that range from common attack patterns, such as ransomware and denial-of-service, to attacks from sophisticated and persistent 
adversaries, including nation state actors, that target companies with innovative technology. Our customers, vendors and other third-party partners face 
similar cybersecurity threats, and a cybersecurity incident impacting us or any of these entities could materially adversely affect our operations, 
performance and results of operations. These cybersecurity threats and related risks make it imperative that we carefully execute our cybersecurity 
operations, strategy and governance.

The Board of Directors are informed of cybersecurity risks and provide oversight to the executive management team with the day-to-day responsibility of 
cybersecurity functions, auditing and budget. Senior leadership, including our Chief Information Security Officer (CISO), regularly briefs the Board of 
Directors on our cybersecurity and information security posture and the Board of Directors is apprised of cybersecurity incidents deemed to impair data 
confidentiality, integrity and/or availability. In the event of an incident, we intend to follow our customized incident response playbooks, which outline the 
steps to be followed from incident detection to mitigation, recovery and notification, including notifying functional areas (e.g. legal), as well as senior 
leadership and the Board, as appropriate. Our procedures vary slightly depending on the type of incident at issue (e.g., account compromise, malware, data 
loss) as well as the data compromised.

Our corporate information security team, led by our CISO, is responsible for our overall information security strategy, policy, security engineering, security 
operations (as a second line of defense) and cyber threat detection and response. The current CISO has ten years’ experience in cybersecurity and 35 years 
as an information technology professional. Given that our CISO has more than 25 years at the Company in multiple positions, he helped incubate and grow 
our corporate information security team into what it is today. Our information security management philosophy is one of cyber risk prevention and we have 
the ultimate goal of preventing cyber incidents. Simultaneously, our information security team focuses on increasing our system resilience to minimize data 
breach (or other compromise) business impact should an incident occur. Cybersecurity is not the sole responsibility of our information security team. Our 
Security team meets with business leaders regularly and works closely with internal departments to keep security at the forefront. Our employees and 
vendors also play a role in our company’s cybersecurity efforts. Through our cybersecurity awareness training and other team training we are fostering a 
culture that all employees and vendors have a role in our cybersecurity defenses.

The corporate information security team has implemented a governance structure and processes to assess, identify, manage and report cybersecurity risks. 
We also have threat intelligence and insider threat programs to identify external and internal threats, and to mitigate those threats in a timely manner to the 
best of our ability. In addition, we have developed security corporate practices, controls, and frameworks, which we believe enhance our ability to identify 
and manage cybersecurity risks.

Third parties also play a role in our cybersecurity and supplement our program. We engage third-party services in some areas of our business to conduct 
evaluations of our security controls, whether through penetration testing, independent audits or consulting on best practices to address new challenges. 

We employ risk management functionality and document enterprise information security risks. Our information security team maintains documentation to 
assess risk and mitigate cyber risk in alignment with risk (understanding general impact and likelihood of risk exploitation), resources, and business 
process. Cybersecurity risks are tracked throughout the risk management process from risk mitigation to ultimate completion of remediation.  From time-to-
time significant risks may be escalated to the executive management team and/or the Board in the existing executive management processes for 
cybersecurity and Board briefing schedule.

40

 
Table of Contents

We rely on our indirect sales channel partners and supply chain to deliver our products and services to our customers, and a cybersecurity incident at a 
channel partner, supplier, subcontractor or joint venture partner could materially adversely impact us. We also contractually flow cybersecurity regulatory 
requirements to our subcontractors in alignment with legal and contractual obligations. Extensive international law and US-sector specific laws pertaining 
to privacy and data security may create challenges for our supply chain and increase costs as we continue to flow down legal obligations.

Despite our careful planning, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us. 
While the Company maintains cybersecurity insurance, the costs related to cybersecurity threats or disruptions may not be fully insured. See Item 1A. 
“Risk Factors” for a discussion of cybersecurity risks.

Item 2. Properties

Our corporate headquarters are located in Troy, Michigan. We own our corporate headquarters facility, and an undeveloped parcel of land adjacent to our 
headquarters, which we may develop over the next few years. 

We lease or sublease all of our other domestic and international offices. We expect to add facilities as we grow our employee base and expand 
geographically. We do not manage our facilities by segment because they may be used for multiple purposes, such as administration, sales, and 
development. We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space 
will be available to accommodate expansion of our operations.

Item 3. Legal Proceedings

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. We have received, and may in the future continue 
to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation may be necessary to 
defend ourselves, our partners and our customers by determining the scope, enforceability and validity of third-party proprietary rights, or to establish and 
enforce our proprietary rights. The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can 
have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 4. Mine Safety Disclosures

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information for Common Stock

Our Class A common stock began trading on the Nasdaq Global Select Market under the symbol “ALTR” on November 1, 2017. 

Our Class B common stock is not listed nor traded on any stock exchange.

Holders

As of February 14, 2024, there were approximately 400 registered stockholders of our Class A common stock and 4 registered stockholders of our Class B 
common stock. We are unable to estimate the total number of stockholders because many of our shares of Class A common stock are held by brokers, 
banks or other institutions on behalf of stockholders.

Dividends

We have never declared or paid any cash dividends on our common stock. We currently do not anticipate paying any dividends on our common stock in the 
foreseeable future. The terms of our 2019 Amended Credit Agreement also restrict our ability to pay dividends, and we may also enter into credit 
agreements or other borrowing arrangements in the future that will restrict our ability to declare or pay cash dividends on our capital stock. Any future 
determination regarding the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then-existing 
conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects, and other factors our board 
of directors may deem relevant. There can be no assurance that any dividends will be paid in the future. 

Performance Graph 

The following shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or incorporated by reference 
into any of our other filings under the Securities Exchange Act of 1934, as amended, or the Securities Act.

The graph below compares the cumulative total stockholder return on our Class A common stock with the cumulative total return on the Nasdaq Composite 
Index and the Nasdaq Computer Index. The graph assumes $100 was invested at the market close on December 31, 2018, in our Class A common stock, the

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated 
financial statements (and notes thereto) for the year ended December 31, 2023 included elsewhere in this Annual Report on Form 10-K. This discussion 
contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that 
could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in “Risk factors” and “Cautionary 
Note Regarding Forward-Looking Statements” included elsewhere in this Annual Report on Form 10-K.

Overview

We are a global leader in computational science and artificial intelligence enabling organizations across broad industry segments to drive smarter decisions 
in an increasingly connected world. We deliver software and cloud solutions in the areas of simulation and design, high-performance computing (“HPC”), 
data analytics, and artificial intelligence (“AI”). Our products and services leverage computational intelligence to drive innovation for a more connected, 
safe, and sustainable future.

Our simulation and AI-driven approach to innovation is powered by our broad portfolio of high-fidelity and high-performance physics solvers, our market-
leading technology for optimization and HPC, and our end-to-end platform for developing AI and Internet of Things (“IoT”) solutions. Our integrated suite 
of software optimizes design performance across multiple disciplines encompassing structures, motion, fluids, thermal, electromagnetics, system modeling, 
and embedded systems, while also providing AI solutions and true-to-life visualization and rendering. Our HPC solutions maximize the efficient utilization 
of complex compute resources and streamline the workflow management of compute-intensive tasks for applications including AI, modeling and 
simulation, and visualization. Our data analytics, AI and IoT products include data preparation, data science, MLOps, orchestration, and visualization 
solutions that fuel engineering, scientific, and business decisions.

Altair’s software products represent a comprehensive, open architecture solution for simulation, HPC, data analytics, and AI to empower decision making 
for improved product design and development, manufacturing, energy management and exploration, financial services, health care, and retail operations. 
We believe Altair’s solutions are compelling due to their openness and usability.

Altair’s products offer a comprehensive set of technologies to design and optimize high-performance, efficient, innovative and sustainable products and 
processes in an increasingly connected world. Our products are categorized by: 

•

•

•

Physics Simulation and Concept Design;

High Performance and Cloud Computing; and 

Data Analytics, AI, IoT and Smart Product Development. 

Altair also provides Client Engineering Services, or CES, to support our customers with long-term ongoing expertise. This has the benefit of embedding us 
within customers, deepening our understanding of their processes, and allowing us to more quickly perceive trends in the overall market. Our presence at 
our customers’ sites helps us to better tailor our software products’ research and development, or R&D, and sales initiatives.

Licensing 

There are two licensing methods we employ to deliver our software solutions:  

• Most products are available under our unique, patented units-based licensing model known as Altair Units.

•

A small subset of our products is available on a node-locked, or hardware specific, and named-user basis. This is especially true for our high-
performance computing solutions.

Altair pioneered Altair Units, a patented units-based subscription licensing model for software and other digital content. This units-based subscription 
licensing model allows flexible and shared access to our offerings, along with more than 150 partner products. Our customers license a pool of units for 
their organizations giving individual users access to our portfolio of software applications as well as our growing portfolio of partner products. We believe 
our units-based subscription licensing model lowers barriers to adoption, creates broad engagement, encourages users to work within our ecosystem, and 
increases revenue. This, in turn, helps drive our recurring software license rate which has been on average approximately 91% over the past five years. 
Historically, approximately 60% of new software revenue comes from expansion within existing customers.

Acquisitions

In September 2023, we acquired OmniQuest, a Michigan based optimization software company. OmniQuest's flagship product, Genesis, is an advanced 
structural analysis and optimization software that uses the finite element to solve problems with many variables and constraints. OmniQuest will enhance 
our optimization leadership in the market driving lightweight and structurally efficient designs across the globe.

In July 2023, we acquired the OmniV technology from XLDyn, LLC. OmniV is a vendor agnostic MBSE requirements management solution. This 
technology will enhance our ability to engage in projects involving digital twins, simulation data management, and engineering data analytics.

We believe that our recent acquisitions result in certain benefits, including expanding our portfolio of software and products and enabling us to better serve 
our customer’s requests for data analytics and simulation technology. However, to realize some of these anticipated benefits, the acquired businesses must 
be successfully integrated. The success of these acquisitions will depend in part on our ability to realize these anticipated benefits. We may fail to realize 
the anticipated benefits of these acquisitions for a variety of reasons.

Factors affecting our performance

We believe that our future success will depend on many factors, including those described below. While these areas present significant opportunity, they 
also present risks that we must manage to achieve successful results. If we are unable to address these challenges, our business, operating results and 
prospects could be harmed. See Part I, Item 1A. – Risk Factors included elsewhere in this Annual Report on Form 10-K.

Seasonality and quarterly results

Our billings have historically been highest in the first and fourth quarters of any calendar year and may vary in future quarters. The timing of recording 
billings and the corresponding effect on our cash flows may vary due to the seasonality of the purchasing patterns of our customers. In addition, the timing 
of the recognition of revenue, the amount and timing of operating expenses, including employee compensation, sales and marketing activities, and capital 
expenditures, may vary from quarter-to-quarter which may cause our reported results to fluctuate significantly. Furthermore, we may choose to grow our 
business for the long-term rather than optimize for profitability or cash flows for a particular shorter-term period. This seasonality or the occurrence of any 
of the factors above may cause our results of operations to vary and our financial statements may not fully reflect the underlying performance of our 
business.

Foreign currency fluctuations

Because of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, as well as our 
transactions that are denominated in foreign currencies, including the Euro, British Pound Sterling, Indian Rupee, Japanese Yen, and Chinese Yuan. To 
identify changes in our underlying business without regard to the impact of currency fluctuations, we evaluate certain of our operating results both on an as 
reported basis, as well as on a constant currency basis. Our 2023 revenue and profit were adversely affected relative to the prior year by changes in foreign 
currency rates and we anticipate that this may continue in 2024.

Business segments

We have identified two reportable segments: Software and Client Engineering Services:

•

•

Software —Our Software segment includes software, software services, and software related services. The software component of this 
segment includes our portfolio of software products including our solvers and optimization technology products, high-performance 
computing software applications and hardware products, modeling and visualization tools, data analytics and analysis products, IoT platform 
and analytics tools as well as support and the complementary software products we offer through our Altair Partner Alliance, or APA. The 
APA includes technologies ranging from computational fluid dynamics and fatigue to manufacturing process simulation and cost estimation. 
The software services and related services component of this segment includes consulting, implementation services, and training focused on 
product design and development expertise and analysis from the component level up to complete product engineering at any stage of the 
lifecycle.

Client Engineering Services — Our client engineering services, or CES, segment provides client engineering services to support our 
customers with long-term, ongoing expertise. We operate our CES business by hiring engineers and data 

45

 
Table of Contents

scientists for placement at a customer site for specific customer-directed assignments. We employ and pay them only for the duration of the 
placement.

Our other businesses which do not meet the criteria to be separate reportable segments are combined and reported as “Other” which represents innovative 
services and products, including Toggled, our LED lighting business. Toggled is focused on developing and selling next-generation solid state lighting 
technology along with communication and control protocols based on our intellectual property for the direct replacement of fluorescent light tubes with 
LED lamps. Other businesses combined within Other include potential services and product concepts that are still in their development stages.

For additional information about our reportable segments and other businesses, see Note 17 in the Notes to consolidated financial statements in Item 15, 
Part IV of this Annual Report on Form 10-K.

Components of results of operations 

Revenue

Software

Software revenue is principally comprised of subscription licenses, and to a lesser extent, perpetual licenses and associated maintenance and support fees. 
Subscriptions are typically governed by contracts with annual terms which include product updates, maintenance and support. We generally recognize 
software license revenue up front, while maintenance and support revenue are generally recognized over the term of the contract. To a much lesser extent, 
Software also includes revenue from the sale of hardware products.

Software revenue also includes consulting, implementation services and training. We generally recognize revenue for software services as those services are 
performed.

Software related services

Consulting services from product design and development projects are considered distinct performance obligations and are provided to customers on a 
time-and-materials, or T&M, or fixed-price basis. We recognize services revenue from our T&M contracts using input-based estimates, utilizing direct 
labor and contractually agreed-upon hourly rates as the input measure. For fixed-price contracts, software services revenue is recognized over time using a 
method that measures the extent of progress towards completion of a performance obligation, generally using a cost-input method where revenue is 
recognized based on the proportion of total cost incurred to estimated total costs at completion. 

Client engineering services

We operate our CES business by hiring engineers and data scientists for placement at a customer site for specific customer-directed assignments. We 
employ and pay them only for the duration of the placement. 

Our CES business generates revenue from placing simulation specialists, industrial designers, design engineers, materials experts, development engineers, 
manufacturing engineers, and information technology specialists. We recognize CES revenue based upon hours worked and contractually agreed-upon 
hourly rates.

Other

Our other revenue consists primarily of revenue related to our LED lighting business operated out of our wholly-owned subsidiary, Toggled. Toggled 
designs, and sources through contract manufacturers, LED lighting and related products for sale to consumers and businesses. We also generate revenue 
through royalties from licensing Toggled technology to third-party manufacturers and resellers.

Cost of revenue

Cost of software 

Cost of software revenue consists of expenses related to software licensing, hardware sales and customer support. Significant expenses include employee 
compensation and related costs for support team members, including salaries, benefits, bonuses and stock-based compensation, as well as hardware costs, 
travel costs, certain data center and facility costs and royalties for third-party software products available to customers through our products or as part of 
our APA.

46

 
Table of Contents

Cost of software related services

Cost of software services revenue consists of personnel and related costs, such as salaries, benefits, bonuses and stock-based compensation, as well as travel 
expenses.

Cost of client engineering services

Cost of client engineering services revenue consists primarily of employee compensation and related costs. We employ and pay them only for the duration 
of the placement at a customer site. 

Cost of other

Cost of other revenue includes the cost of LED lighting products and freight related to products sold to retail and commercial sales channels.

Operating expenses

Operating expenses, as defined and discussed below, support all the products and services that we provide to our customers and, as a result, they are 
presented in aggregate.

Research and development

Research and development expenses consist primarily of employee compensation and related costs associated with our development team, including 
salaries, benefits, bonuses, professional consulting and development fees, and stock-based compensation expense. Certain indirect costs, including IT, 
facilities, and depreciation expenses, are allocated based on global headcount. Our research and development efforts are focused on enhancing the 
functionality, breadth and scalability of our software, addressing new use cases, and developing additional innovative technologies. Timely development of 
new products is essential to maintaining our competitive position, and we release new versions of our software on a regular basis. All software development 
costs are expensed as incurred as our current software development process is essentially completed concurrent with the establishment of technological 
feasibility.

Sales and marketing

Sales and marketing expenses consist primarily of employee compensation and related costs associated with our sales and marketing staff, including 
salaries, benefits, bonuses, commissions and stock-based compensation, as well as costs relating to our marketing and business development programs 
including trade shows and events. Certain indirect costs, including IT, facilities, and depreciation expenses, are allocated based on global headcount. We 
intend to continue to invest resources in our sales and marketing initiatives to drive growth and extend our market position.

General and administrative

General and administrative expenses consist of employee compensation and related costs for executive, finance, legal, human resources, recruiting, and 
employee-related information technology and administrative personnel, including salaries, benefits, bonuses and stock-based compensation expense, 
professional fees for external legal and accounting services, recruiting and other consulting services. Certain indirect costs, including IT, facilities, and 
depreciation expenses, are allocated based on global headcount.

Amortization of intangible assets

Amortization of intangible assets consists primarily of amortization of intangibles associated with acquisitions. We expect to incur additional amortization 
expense resulting from future strategic acquisitions.

Other operating expense (income), net

Other operating expense (income), net consists primarily of government subsidies, primarily in Europe, in the form of grant income associated with certain 
of our research and development activities, mark-to-market adjustments for contingent consideration, and other items as disclosed.

47

 
Table of Contents

Interest expense

Interest expense consists of interest expense on our outstanding indebtedness and amortization of debt issuance costs.

Other (income) expense, net

Other (income) expense, net is comprised primarily of foreign currency exchange gains and losses generated from the settlement and remeasurement of 
transactions denominated in currencies other than the functional currency of our operating units, and interest income on invested cash. Other (income) 
expense, net also includes the expense on the repurchase of our 0.250% convertible senior notes which  mature on June 1, 2024, (the "2024 Notes") for the 
year ended December 31, 2022.

Income tax expense 

Income tax expense is comprised primarily of income taxes related to United States, foreign, and state jurisdictions in which we conduct business. Income 
tax expense also includes taxes withheld outside of the United States attributable to remittances to the Company from certain foreign subsidiaries. We 
record interest and penalties related to income tax matters as income tax expense. We expect the amount of income tax expense (benefit), if any, to vary 
each reporting period depending upon fluctuations in our quantum and tax jurisdictional mix of income (loss). We have substantial United States foreign tax 
credit carryforwards which begin to expire in 2027, and research and development tax credits which began to expire in 2018. The ability to utilize these tax 
attributes is highly dependent upon our ability to generate taxable income in the United States in the future.

Our future effective annual tax rate may be materially impacted by the amount of benefits and charges from tax amounts associated with our foreign 
earnings that are taxed at rates different from the federal statutory rate, the taxation of the foreign earnings in the U.S. under the Global Intangible Low-
Taxed Income, or GILTI, and Foreign Derived Intangible Income, or FDII, regimes, changes in valuation allowances, level of profit before tax, accounting 
for uncertain tax positions, stock-based compensation, business combinations, payments to the Company from certain foreign subsidiaries, closure of 
statute of limitations, settlements of tax audits, and changes in tax laws including United States tax law changes that were enacted in December 2017. A 
significant amount of our earnings is generated in our EMEA and APAC regions. Our future effective tax rates may be adversely affected to the extent 
earnings are lower than anticipated in countries where we have lower statutory tax rates. 

As of December 31, 2023 and 2022, we had gross deferred tax assets, or DTAs, of $208.5 million and $179.8 million, respectively, primarily related to 
capitalized research and development expenses, net operating loss carryforwards, tax credits and share-based compensation. We are entitled to a United 
States federal tax deduction when non-qualified stock options, or NSOs, are exercised. For 2023 tax year, we recorded a net increase in the valuation 
allowance of $29.9 million for the gross DTAs. Our ability to utilize any net operating losses or tax credits may be limited under provisions of the Code if 
we undergo an ownership change after our IPO (generally defined as a greater than 50-percentage point cumulative change (by value) in the equity 
ownership of certain stockholders over a rolling three-year period). We also inherited net operating losses, or NOLs, from the acquisitions of Univa and 
RapidMiner, which are subject to specific limitations on usage. We may also be unable to realize our tax credit carryforwards prior to their expiration.

For tax years beginning on or after January 1, 2022, the Tax Act eliminates the option to currently deduct certain qualifying research and development 
expenses and requires taxpayers to capitalize and amortize such expenses over five years for research activities performed in the United States and 15 years 
for research activities performed outside the United States pursuant to Section 174 of the Code. Although Congress is considering legislation that would 
repeal or defer this capitalization and amortization requirement, it is not certain that this provision will be repealed or otherwise modified. If the 
requirement is not repealed or replaced, it will increase our U.S. federal and state cash taxes and reduce cash flows in fiscal year 2024 and future years.

Based on the evidence available, including a lack of taxable earnings in the United States, we recorded a valuation allowance against substantially all of our 
net deferred tax assets in the United States. If a change in judgment regarding this valuation allowance were to occur in the future, we will record a 
potentially material deferred tax benefit, which could result in a favorable impact on our effective tax rate in that period. The utilization of tax attributes to 
offset taxable income reduces the amount of deferred tax assets subject to a valuation allowance.

Change in Classification of Indirect Costs

As indicated in Note 2 to the Consolidated Financial Statements, beginning in the first quarter of 2023, we refined the classification of certain indirect costs 
to reflect the way we are now reviewing the information in decision making and to improve comparability with peers. These indirect costs include certain 
IT, facilities, and depreciation expenses that were previously reported primarily in General and administrative expense. These indirect costs have now been 
reclassified to Research and development, Sales and marketing, and General and administrative expenses based on global headcount. We believe this 
refined methodology better reflects the nature of the costs and financial performance of the Company.

As a result, the consolidated statements of operations have been recast for prior periods presented to reflect the effects of the changes to Research and 
development, Sales and marketing, and General and administrative expense. There was no net impact to total operating expenses, income from operations, 
net income or net income per share for any periods presented. The consolidated balance sheets, consolidated statements of comprehensive income, 
consolidated statements of changes in stockholders’ equity, and the consolidated statements of cash flows were not affected by changes in the presentation 
of these costs.

The effective tax rate was 171% and (54%) for the year ended December 31, 2023 and 2022, respectively. The tax rate is affected by the Company being a 
U.S. resident taxpayer, the tax rates in the U.S. and other jurisdictions in which the Company operates, the relative amount of income earned by jurisdiction 
and the relative amount of losses or income for which no benefit or expense is recognized due to a valuation allowance. The effective tax rate was impacted 
by the geographic income mix in 2023 as compared to 2022, primarily related to a United States pre-tax loss of $21.8 million for the year ended December 
31, 2023, for which a tax benefit was not recognized due to the valuation allowance, compared to a United States pre-tax loss of $62.7 million for the year 
ended December 31, 2022, for which a tax benefit was not recognized due to the valuation allowance as well as changes in uncertain tax positions. Income 
tax expense also includes taxes withheld outside of the United States attributable to remittances to the Company from certain foreign subsidiaries for which 
offsetting tax credits are not recognizable due to valuation allowance considerations.

Net loss was $8.9 million and $43.4 million for the years ended December 31, 2023 and 2022, respectively. The reduction in net loss for the year ended

and a loss on the mark-to-market adjustment of contingent consideration as compared to the year ended December 31, 2022. The net loss for the year ended 
December 31, 2022 included expense recognized on the repurchase of a portion of our 2024 Notes, and a gain on the mark-to-market adjustment of

Non-GAAP financial measures

We monitor the following key non-GAAP (United States generally accepted accounting principles) financial and operating metrics to help us evaluate our 
business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions. In analyzing and planning 
for our business, we supplement our use of GAAP financial measures with non-GAAP financial measures, including Billings as a liquidity measure, 
Adjusted EBITDA as a performance measure and Free Cash Flow as a liquidity measure.

Billings. Billings consists of our total revenue plus the change in our deferred revenue, excluding deferred revenue from acquisitions during the period. 
Given that we generally bill our customers at the time of sale but typically recognize a portion of the related revenue ratably over time, management 
believes that Billings is a meaningful way to measure and monitor our ability to provide our business with the working capital generated by upfront 
payments from our customers. 

Billings increased by $24.2 million, or 4%, for the year ended December 31, 2023, as compared to the year ended December 31, 2022. This increase in 
Billings was attributable to an increase in Software segment billings.

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) adjusted for income tax expense (benefit), interest expense, interest income and other, 
depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other special items as determined by 
management. We believe that Adjusted EBITDA is a meaningful measure of performance as it is commonly utilized by us and the investment community 
to analyze operating performance in our industry. 

Adjusted EBITDA increased by $20.5 million, or 19%, for the year ended December 31, 2023, as compared to the year ended December 31, 2022. This 
increase in Adjusted EBITDA was primarily attributable to the increase in gross profit, partially offset by an increase in operating expenses.

Free Cash Flow. Free Cash Flow is a non-GAAP financial measure that we calculate as cash flow provided by operating activities less capital expenditures. 
We believe that Free Cash Flow is useful in analyzing our ability to service and repay debt, when applicable, and return value directly to stockholders. 

Net cash provided by operating activities for the year ended December 31, 2023, was $127.3 million, which reflects an increase of $87.7 million compared 
to the year ended December 31, 2022. Free Cash Flow increased $87.2 million, or 291%, for the year ended December 31, 2023, as compared to year ended 
December 31, 2022. This increase in Free Cash Flow was primarily attributable to a non-recurring $65.9 million payment in the prior year on an existing 
legal judgment against World Programming, and an improvement in our cash-related profitability for the year ended December 31, 2023, as compared to 
the year ended December 31, 2022.

These non-GAAP financial measures reflect an additional way of viewing aspects of our business that, when viewed with our GAAP results and the 
accompanying reconciliations to corresponding GAAP financial measures included in the tables below, may provide a more complete understanding of 
factors and trends affecting our business. These non-GAAP financial measures should not be relied upon to the exclusion of GAAP financial measures and 
are by definition an incomplete understanding of the Company and must be considered in conjunction with GAAP measures.

We believe that the non-GAAP measures disclosed herein are only useful as an additional tool to help management and investors make informed decisions 
about our financial and operating performance and liquidity. By definition, non-GAAP measures do not give a full understanding of the Company. To be 
truly valuable, they must be used in conjunction with the comparable GAAP measures. In addition, non-GAAP financial measures are not standardized. It 
may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. We 
strongly encourage investors to review our consolidated financial statements and the notes thereto in their entirety and not to rely on any single financial 
measure.

Recurring Software License Rate. A key factor to our success is our recurring software license rate which we measure through billings, primarily derived 
from annual renewals of our existing subscription customer agreements. We calculate our recurring software license rate for a particular period by dividing 
(i) the sum of software term-based license billings, software license maintenance billings, and 20% of software perpetual license billings which we believe 
approximates maintenance as an element of the arrangement by (ii) the total software license, including all term-based subscriptions, maintenance and 
perpetual license billings from all customers for that period. Our recurring software license rate was 93%, 92%, and 92% for the years ended December 31, 
2023, 2022 and 2021, respectively.

Liquidity and capital resources

As of December 31, 2023, our principal sources of liquidity were $467.5 million in cash and cash equivalents and $200.0 million availability on our credit 
facility. As of December 31, 2023, our outstanding debt consists of $81.7 million and $230.0 million convertible notes due in 2024 and 2027, respectively.

During the period ended December 31, 2023, the conditions allowing holders of the 2027 Notes to convert were not met. Therefore, the 2027 Notes were 
classified as long-term debt on the consolidated balance sheet as of December 31, 2023. We have the ability to settle the 2027 Notes in cash, shares of our 
common stock, or a combination of cash and shares of our common stock at our own election. 

The 2024 Notes are convertible at the option of the holders and mature on June 1, 2024, and were classified as current on the consolidated balance sheet as 
of December 31, 2023. We have elected to settle the 2024 Notes par value of $81.7 million in cash, which we currently expect to fund from our available 
cash, and will settle the premium of $65.9 million in shares of our Class A common stock.

In May 2023, our board of directors approved an increase under our existing stock repurchase program from $50.0 million to $75.0 million of our 
outstanding Class A Common Stock. During the year ended December 31, 2023, under our stock repurchase program, we repurchased 91,273 shares of our 
Class A Common Stock at an average price of $46.63 per share for a total cost of approximately $4.3 million. As of December 31, 2023, approximately 
$49.1 million of shares remained available for repurchase under the program. 

We continue to evaluate possible acquisitions and other strategic transactions designed to expand our business. As a result, our expected uses of cash could 
change, our cash position could be reduced, or we may incur additional debt obligations to the extent we complete additional acquisitions. 

Our existing cash and cash equivalents may fluctuate during fiscal 2024, due to changes in our planned cash expenditures, including changes in incremental 
costs such as direct costs and integration costs related to acquisitions. Cash from operations could also be affected by various risks and uncertainties, 
including, but not limited to, the effects of geopolitical events. It is possible that certain customers may unilaterally decide to extend payments on accounts 
receivable, however our customer base is comprised primarily of larger organizations with typically strong liquidity and capital resources.   

We believe that our existing cash balances, together with funds generated from operations and amounts available under our credit facility, will be sufficient 
to finance our operations and meet our foreseeable cash requirements for the next twelve months. We also believe that our financial resources, along with 
managing discretionary expenses, will allow us to manage our business operations for the foreseeable future and withstand geopolitical events, which could 
include reductions in revenue and delays in payments from customers and partners. We will continue to evaluate our financial position as developments 
evolve relating to global unrest.

Revolving credit facility

As of December 31, 2023, there were no outstanding borrowings under the 2019 Amended Credit Agreement and there was $200.0 million available for 
future borrowing. The 2019 Amended Credit Agreement is available for general corporate purposes, including working capital, capital expenditures and 
permitted acquisitions. 

The 2019 Amended Credit Agreement is secured by collateral including (i) substantially all of our properties and assets, and the properties and assets of our 
domestic subsidiaries but excluding any patents, copyrights, patent applications or copyright applications or any trade secrets or software products and (ii) 
pledges of the equity interests in all present and future domestic subsidiaries (subject to certain exceptions as provided for under the 2019 Amended Credit 
Agreement). Our direct and indirect domestic subsidiaries are guarantors of all of the obligations under the 2019 Amended Credit Agreement. In addition, 
the 2019 Amended Credit Agreement contains financial covenants which require, as of the end of each fiscal quarter, a Senior Secured Leverage Ratio not 
greater than 3.0 to 1.0, as such terms are defined in the 2019 Amended Credit Agreement. As of December 31, 2023, we were in compliance with all 
financial covenants. For additional information about the 2019 Amended Credit Agreement, see Note 7 in the Notes to consolidated financial statements in 
Item 15, Part IV of this Annual Report on Form 10-K.

Cash flows

As of December 31, 2023 and 2022, respectively, we had an aggregate of cash and cash equivalents of $467.5 million and $316.1 million, which we held 
for working capital purposes, acquisitions, and capital expenditures. As of December 31, 2023 and 2022, 

56

 
Table of Contents

respectively, $362.5 million and $222.0 million of this aggregate amount was held in the United States, and $98.7 million and $88.3 million was held in the 
APAC and EMEA regions combined, with the remainder held in Canada, Mexico, and South America.

Other than statutory limitations, there are no significant restrictions on the ability of our subsidiaries to pay dividends or make other distributions to Altair. 
Based on our current liquidity needs and repatriation strategies, we expect that we can manage our global liquidity needs without material adverse tax 
implications.

year ended December 31, 2022. For the year ended December 31, 2022, we paid $96.7 million for the acquisition of RapidMiner, and an additional $47.8 
million related to other business acquisitions and investments. 

Net cash provided by financing activities

Net cash provided by financing activities for the year ended December 31, 2023, was $37.8 million, which reflects an increase in cash provided of $14.8 
million compared with the year ended December 31, 2022. For the year ended December 31, 2023, we received $36.1 million from the exercise of common 
stock options. For the year ended December 31, 2022, we received aggregate proceeds of $224.3 million from the issuance of our 2027 Notes, net of certain 
discounts and commissions, partially offset by $192.4 million proceeds used for the repurchase of a portion of our 2024 Notes. In addition, for the years 
ended December 31 2023 and 2022, we used $6.3 million and $19.7 million, respectively, to repurchase shares of our Class A Common Stock under our 
stock repurchase program. 

Effect of exchange rate changes on cash, cash equivalents and restricted cash

There was a favorable effect of exchange rate changes on cash, cash equivalents and restricted cash of $1.4 million for the year ended December 31, 2023, 
compared to an adverse effect of exchange rate changes on cash, cash equivalents and restricted cash of $5.1 million for the year ended December 31, 2022. 

Commitments 

As of December 31, 2023, our principal commitments consist of our $81.7 million and $230.0 million convertible notes due in 2024 and 2027, respectively. 

As of December 31, 2023, we had a net benefit liability of $16.9 million associated with our pension and post-retirement benefit plans. For additional 
information on pension and other post-retirement benefits, including expected benefit payments for the next 10 years, see Note 14 in the Notes to 
consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

We have non-cancelable contractual agreements primarily related to the hosting of our data storage processing, storage, and other computing services, as 
well as other commitments. We had $40.0 million in non-cancelable contractual agreements as of December 31, 2023, primarily due within three years.

We also have approximately $39.5 million of tax liabilities associated with uncertain tax positions. There is a high degree of uncertainty regarding the 
future cash outflows associated with these amounts. For additional discussion of uncertain tax positions, see Note 12 in the Notes to consolidated financial 
statements included elsewhere in this Annual Report on Form 10-K.

Critical accounting estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been 
prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported 
amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues 
generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we 
believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities 
that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that 
the accounting estimates discussed below are critical to understanding our historical and future performance, as these estimates relate to the more 
significant areas involving management’s judgments and assumptions. Refer to Note 2 to our consolidated financial statements for our significant 
accounting policies related to our critical accounting estimates.

Revenue recognition

We generate revenue from our Software and CES segments and our other businesses. Revenue is recognized by identifying a contract with a customer, 
identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in 
the contract, and recognizing revenue when (or as) we satisfy a performance obligation.

Software

Software revenue includes product revenue from software product licensing arrangements, related services consisting of software maintenance and support 
in the form of post-contract customer support (PCS or maintenance) and professional services such as consulting and training services. Software products 
are sold to customers primarily under a term-based software licensing model and to a lesser degree, perpetual software licenses. We enter into contracts that 
include combinations of products, maintenance and services, which are accounted for as separate performance obligations with differing revenue 
recognition patterns.

Most term-based software license agreements include our patented units-based subscription model which allows customers to license a pool of units for 
their organizations, providing individual users flexible access to our portfolio of engineering software applications as well as to our growing portfolio of 
partner products. The amount of software usage is limited by the number of the units licensed by the customer. Revenue from these arrangements is fixed 
(based on the units licensed) and is not based on actual customer usage of each software product.

Revenue from term-based software licenses is classified as license software revenue. Term-based licenses are sold only as a bundled arrangement that 
includes the rights to a term software license and PCS, which includes unspecified technical enhancements and customer support. Maximizing the use of 
observable inputs, we determined that a majority of the estimated standalone selling price of the term-based license is attributable to the term license and a 
minority is attributable to the PCS. The license component is recognized as revenue upon the later of delivery of the licensed product or the beginning of 
the license period. The PCS is classified as maintenance revenue and is recognized ratably over the term of the contract, as we provide the PCS benefit over 
time.

In addition to term-based software licenses, we sell perpetual licenses. Typically, our perpetual licenses are sold with PCS, which includes unspecified 
technical enhancements and customer support. Revenue from the software component is classified as license software revenue and is recognized upon the 
later of delivery of the licensed product or the beginning of the license period. We allocate values in bundled perpetual and PCS arrangements based on the 
standalone selling prices of the perpetual license and PCS. Revenue from PCS is classified as maintenance revenue and is recognized ratably over the term 
of the contract, as we satisfy the PCS performance obligation over time.

Revenue from training, consulting and other services is recognized as the services are performed. For contracts in which the service consists of a single 
performance obligation, such as providing a training class to a customer, we recognize revenue upon completion of the performance obligation. For service 
contracts that are longer in duration and often include multiple performance obligations (for 

58

 
Table of Contents

example, both training and consulting), we measure the progress toward completion of the obligations and recognize revenue accordingly. In measuring 
progress towards the completion of performance obligations, we typically utilize output-based estimates for services with contractual billing arrangements 
that are not based on time and materials, and estimate output based on the total tasks completed as compared to the total tasks required for each work 
contract. Input-based estimates are utilized for services that involve general consultations with contractual billing arrangements based on time and 
materials, utilizing direct labor as the input measure.

We also execute arrangements through indirect channel partners in which the channel partners are authorized to market and distribute our software products 
to end users of our products and services in specified territories. In sales facilitated by channel partners, the channel partner generally bears the risk of 
collection from the end-user customer. We recognize revenue from transactions with channel partners in a manner consistent with the direct sales described 
above for both perpetual and term-based licenses. Revenue from channel partner transactions is the amount remitted to us by the channel partners. This 
amount includes a fee for PCS that is compensation for providing technical enhancements and the second level of technical support to the end user, which is 
recognized over the period that PCS is to be provided. We do not offer right of return, product rotation or price protection to any of its channel partners.

Some of our contracts with customers contain multiple performance obligations. Judgment is required in determining whether each performance obligation 
is distinct. We allocate the transaction price for each contract to each performance obligation based on the relative standalone selling price, or SSP, for each 
performance obligation within each contract. The SSP is the price that we would sell a promised service separately to one of our customers. Judgment is 
required to determine the SSP for each distinct performance obligation. We estimate SSP using information such as past transactions, internally approved 
pricing guidelines related to the performance obligations and other information reasonably available to us.

Non-income related taxes collected from customers and remitted to governmental authorities are recorded on the consolidated balance sheet as accounts 
receivable, net and other accrued expenses and current liabilities. These amounts are reported on a net basis in the consolidated statements of operations 
and do not impact reported revenues or expenses. Certain hardware revenue is included within software revenue and is recognized when all revenue 
recognition criteria stated above are met, which is generally when the products are delivered to end customers.

Acquisitions 

We account for acquisitions of entities that include inputs and processes and have the ability to create outputs as business combinations. We allocate the fair 
value of purchase consideration of acquired businesses to the identifiable tangible and intangible assets acquired and liabilities assumed in the transaction 
based upon their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. During the 
measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with 
the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities 
assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

We determine the estimated fair values using information available to us and engage independent third-party valuation specialists when necessary. We 
generally use an income approach to determine the fair value of intangible assets acquired. Estimating fair values can be complex and subject to significant 
business judgment. Critical estimates in valuing certain of the intangible assets we have acquired include, but are not limited to, future expected cash flows 
from product sales, customer contracts and acquired technologies, expenses to operate the acquired business, and discount rates. Unanticipated events and 
circumstances may occur that could affect either the accuracy or validity of such assumptions, estimates or actual results. Although we believe the 
assumptions and estimates we have made in the past have been reasonable and appropriate, these estimates are based on historical experience and 
information obtained from the management of the acquired companies and are inherently uncertain.

Income taxes

We utilize the asset and liability method of accounting for income taxes in accordance with ASC 740, Accounting for Income Taxes. Under this method, 
deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities. Deferred tax 
assets and liabilities are measured using the enacted tax rates and statutes that will be in effect when those differences are expected to reverse. Deferred tax 
assets can result from unused operating losses, research and development credits, foreign tax credit carryforwards, and deductions recorded for financial 
statement purposes prior to them being deductible on a tax return. Valuation allowances are provided against net deferred tax assets if, based upon the 
available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. 

59

 
 
Table of Contents

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the reversal of taxable temporary differences. 
We consider, among other available information, scheduled reversals of deferred tax liabilities, projected future taxable income, limitations on the 
availability of tax credit carryforwards, and other evidence assessing the potential realization of deferred tax assets. Adjustments to the valuation allowance 
are included in the tax provision in our consolidated statements of operations in the period they become known or can be estimated.

The valuation allowance is based on our estimates of taxable income for jurisdictions in which we operate and the period over which our deferred tax assets 
may be recoverable. Historically, we have had substantial United States tax credit carryforwards which began to expire in 2018. The ability to utilize these 
DTAs is highly dependent upon our ability to generate taxable income in the United States in the future.

We apply a more-likely-than-not recognition threshold to our accounting for tax uncertainties. We review all of our tax positions and make determinations 
as to whether our tax positions are more likely than not to be sustained upon examination by the relevant taxing authorities. Only those benefits, or 
exposures, that have a greater than fifty percent likelihood of being sustained upon examination by taxing authorities are recognized. Interest and penalties 
related to uncertain tax positions are recorded in income tax expense (benefit) in the consolidated statements of operations.

Recently issued accounting pronouncements

For information regarding recent accounting guidance and the impact of this guidance on our consolidated financial statements, see Note 2 of the Notes to 
consolidated financial statements in Item 15, Part IV of this Annual Report on Form 10-K, which is incorporated by reference.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain global market risks, including foreign currency exchange risk and interest rate risk associated with our debt.

Foreign Currency Risk

As a result of our substantial international operations, we are exposed to foreign currency risks that arise from our normal business operations, including in 
connection with our transactions that are denominated in foreign currencies. In addition, we translate sales and financial results denominated in foreign 
currencies into United States dollars for purposes of our consolidated financial statements. As a result, appreciation of the United States dollar against these 
foreign currencies generally will have a negative impact on our reported revenue and operating income while depreciation of the United States dollar 
against these foreign currencies will generally have a positive effect on reported revenue and operating income.

As of December 31, 2023, we do not have any foreign currency hedging contracts. Based on our current international operations, we do not plan on 
engaging in hedging activities in the near future.

Market Risk and Interest Rate Risk

In June 2022, we issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027 (the "2027 Notes"). In June 2019, we 
issued $230.0 million aggregate principal amount of 0.250% convertible senior notes due 2024 (the "2024 Notes" together with the 2027 Notes 
"Convertible Notes"), of which approximately $148.3 million aggregate principal amount had been repurchased as of December 31, 2023. The 2027 Notes 
and 2024 Notes have fixed annual interest rates at 1.750% and 0.250%, respectively, and, therefore, we do not have interest rate exposure on our 
Convertible Notes. However, the value of the Convertible Notes is exposed to interest rate risk. Generally, the fair market value of our fixed interest rate 
Convertible Notes will increase as interest rates fall and decrease as interest rates rise. In addition, the fair values of the Convertible Notes are affected by 
our stock price. The fair value of the Convertible Notes will generally increase as our Class A common stock price increases in value and will generally 
decrease as our Class A common stock price declines in value. Additionally, we carry the Convertible Notes at face value less unamortized issuance costs 
on our balance sheet, and we present the fair value for required disclosure purposes only.

As of December 31, 2023, we had cash, cash equivalents and restricted cash of $467.6 million, consisting primarily of bank deposits and money market 
funds. As of December 31, 2023, we had no borrowings outstanding under our 2019 Amended Credit Agreement. Such interest-bearing instruments carry a 
degree of interest rate risk; however, historical fluctuations of interest expense have not been significant. 

Interest rate risk relates to the gain/increase or loss/decrease we could incur on our debt balances and interest expense associated with changes in interest 
rates. Changes in interest rates would impact the amount of interest income we realize on our invested cash 

60

balances. It is our policy not to enter into derivative instruments for speculative purposes, and therefore, we hold no derivative instruments for trading 
purposes.

Item 8. Financial Statements and Supplementary Data.

The financial statements required by this Item 8 are included in our consolidated financial statements and set forth in the pages indicated in Part IV, Item 
15(a) of this Annual Report on Form 10-K and are incorporated herein by reference. 

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act) that are designed to ensure 
that information required to be disclosed in periodic reports filed with the SEC under the Securities Exchange Act of 1934 is recorded, processed, 
summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to 
the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required 
disclosure. The Company's management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of 
the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 
1934 (the “Exchange Act”)) as of December 31, 2023. Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer 
have concluded that our disclosure controls and procedures were effective as of December 31, 2023.

(b) Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act 
Rule 13a-15(f) and 15d(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting 
principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or a combination of deficiencies, in internal control 
over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will 
not be prevented or detected on a timely basis.

Our management, including our Chief Executive Officer and Chief Financial Officer, conducted an assessment of the effectiveness of our internal control 
over financial reporting as of December 31, 2023 based on the criteria established by Internal Control – Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (2013 framework). In accordance with guidance issued by the Securities and Exchange 
Commission, companies are permitted to exclude acquisitions from their assessment of internal control over financial reporting for the first fiscal year in 
which the acquisition occurred. Accordingly, we have excluded from our assessment the internal control over financial reporting of OmniQuest which was 
acquired in September 2023 and is included in our December 31, 2023 consolidated financial statements. OmniQuest constituted less than 1% of total and 
net assets (excluding acquired goodwill and intangible assets) as of December 31, 2023, and less than 1% of revenues for the year then ended. 

Based on the evaluation under these frameworks, management has concluded that our internal control over financial reporting was effective as of December 
31, 2023. The results of management’s assessment have been reviewed with the Audit Committee.

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by Ernst & Young LLP, an independent 
registered public accounting firm, as stated in their report which is included elsewhere herein.

(c) Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred 
during the fourth quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over 
financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Altair Engineering Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Altair Engineering Inc. and subsidiaries (the Company) as of December 31, 2023 and 
2022, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders' equity (deficit) and cash flows for each of 
the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our 
opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with U.S. generally 
accepted accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),  the  Company's 
internal  control  over  financial  reporting  as  of  December  31,  2023,  based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the 
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 22, 2024 expressed an unqualified 
opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial 
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  Our  audits  included  performing 
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to 
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits 
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the 
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The  critical  audit  matters  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or 
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) 
involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion 
on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions 
on the critical audit matters or on the accounts or disclosures to which it relates.

Software Revenue Recognition

Description of the 
Matter

  As described in Note 3, the Company’s software contracts with customers typically include promises to transfer licenses and 
services  to  a  customer.  Judgment  is  required  to  determine  if  the  promises  are  separate  performance  obligations  within  the 
context of the arrangement, and if so, the allocation of the transaction price to each  performance obligation. The Company’s 
determination  of  standalone  selling  price  for  performance  obligations  is  based  on  the  midpoint  of  the  range  of  historical 
observable prices for goods and services sold separately. In addition, the Company estimates the standalone selling price for 
certain performance obligations where observable prices are not directly available, or a significant portion of historical prices 
are not within the range. The Company estimates the standalone selling price at contract inception considering all information 
that  is  reasonably  available  and  based  on  the  amount  of  consideration  for  which  the  Company  expects  to  be  entitled  in 
exchange for transferring the promised good or service to the customer. 

Auditing the Company’s estimate of the standalone selling prices in software contracts was challenging and complex due to the 
Company’s  wide  range  of  observable  prices  from  goods  or  services  sold  separately  and  the  estimation  used  for  certain 
performance obligations where observable prices are not available.

Table of Contents

How We Addressed the 
Matter in Our Audit

  We  obtained  an  understanding,  evaluated  the  design  and  tested  the  operating  effectiveness  of  the  Company's  process  and 
controls  to  establish  and  monitor  the  relative  standalone  selling  price  for  each  distinct  performance  obligation  in  software 
contracts.

To test the estimated standalone selling prices, our audit procedures included, among others, evaluating the assumptions used 
by the Company to determine the standalone selling price for each distinct performance obligation in its software contracts. For 
example, we evaluated the methodology used to determine the standalone selling price by testing a historical analysis prepared 
by the Company and practices observed in the industry. We also tested the completeness and accuracy of the data used in the 
analysis and recalculated the standalone selling prices.

We have served as the Company’s auditor since 2015.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Altair Engineering Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Altair Engineering Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework)  (the 
COSO criteria).  In our opinion, Altair Engineering Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2023, based on the COSO criteria.

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the 
effectiveness of internal control over financial reporting did not include the internal controls of OmniQuest, which is included in the December 31, 2023 
consolidated financial statements of the Company and constituted less than 1% of total and net assets (excluding acquired goodwill and intangible assets) as 
of December 31, 2023 and less than 1% of revenues for the year then ended. Our audit of internal control over financial reporting of the Company also did 
not include an evaluation of the internal control over financial reporting of OmniQuest.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),  the  2023 
consolidated financial statements of the Company and our report dated February 22, 2024 expressed an unqualified opinion thereon.  

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of 
internal  control  over  financial  reporting  included  in  the  accompanying  Management’s  Report  on  Internal  Control  over  Financial  Reporting.  Our 
responsibility  is  to  express  an  opinion  on  the  Company’s  internal  control  over  financial  reporting  based  on  our  audit.  We  are  a  public  accounting  firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and 
evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered 
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting 
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control 
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are 
being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of 
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of 
compliance with the policies or procedures may deteriorate.

2. Summary of significant accounting policies

Principles of consolidation

The accompanying consolidated financial statements have been prepared using accounting principles generally accepted in the United States of America 
(“GAAP”). The consolidated financial statements include the results of the Company and its controlled subsidiaries. Intercompany accounts and 
transactions have been eliminated in the consolidated financial statements.

Change in Classification of Indirect Costs

Beginning in the first quarter of 2023, the Company refined its classification of certain indirect costs to reflect the way management is now reviewing the 
information in decision making and to improve comparability with peers. These indirect costs include certain IT, facilities, and depreciation expenses that 
were previously reported primarily in General and administrative expense. These indirect costs have now been reclassified to Research and development, 
Sales and marketing, and General and administrative expenses based on global headcount. Management believes this refined methodology better reflects 
the nature of the costs and financial performance of the Company.

 As a result, the Company’s consolidated statements of operations have been recast for prior periods presented to reflect the effects of the changes to 
Research and development, Sales and marketing, and General and administrative expense. There was no net impact to total operating expenses, income 
from operations, net income or net income per share for any periods presented. The consolidated balance sheets, consolidated statements of comprehensive 
income, consolidated statements of changes in stockholders’ equity, and the consolidated statements of cash flows were not affected by changes in the 
presentation of these costs.

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and reported amounts of 
revenue and expenses during the reporting periods. On an ongoing basis, management evaluates its significant estimates including the stand alone selling 
price, or SSP, for each distinct performance obligation included in customer contracts with multiple performance obligations, the incremental borrowing 
rate used in the valuation of lease liabilities, fair value of convertible senior notes, provision for expected credit losses, tax valuation allowances, liabilities 
for uncertain tax provisions, impairment of goodwill and intangible assets, retirement obligations, useful lives of intangible assets, revenue for fixed price 
contracts, and stock-based compensation. Actual results could differ from those estimates.

Foreign currency translation

The functional currency of the Company’s foreign subsidiaries is their respective local currency. The assets and liabilities of the subsidiaries are translated 
to U.S. dollars at the exchange rate as of the balance sheet date. Equity balances and transactions are translated using historical exchange rates. Revenues 
and expenses are translated at the average exchange rate during the period. Translation adjustments arising from the use of differing exchange rates from 
period to period are recorded as a component of accumulated other comprehensive loss within stockholders’ equity.

All assets and liabilities denominated in a currency other than the functional currency are remeasured into the functional currency with gains and losses 
recognized in foreign currency losses, net, in the consolidated statements of operations. The Company has no transactions which hedge purchase 
commitments and no intercompany balances which are designated as being of a long-term investment in nature.

Revenue recognition

Software revenue

Revenue is derived principally from the licensing of software products and from related maintenance contracts. The Company enters into contracts that 
include combinations of products, maintenance and services, which are accounted for as separate performance obligations with differing revenue 
recognition patterns.

Revenue from term-based software licenses is classified as software revenue. Term-based licenses are sold only as a bundled arrangement that includes the 
rights to a term-based software license and post-contract customer support (PCS), which includes unspecified technical enhancements and customer 
support. Maximizing the use of observable inputs, the Company determined that a majority of the estimated standalone selling prices of the term-based 
license is attributable to the term-based license and a minority is attributable to the PCS. The license component is classified as license revenue and 
recognized as revenue upon the later of delivery of the licensed product or the beginning of the license period. PCS is classified as maintenance and other 
services and is recognized ratably over the term of the contract, as the Company provides the PCS benefit over time as a stand ready to perform obligation.

Table of Contents

In addition to term-based software licenses, the Company sells perpetual licenses. Software revenue is recognized upon the later of delivery of the licensed 
product or the beginning of the license period. Typically, the Company’s perpetual licenses are sold with PCS. The Company allocates value in bundled 
perpetual and PCS arrangements based on the value relationship between the software license and maintenance. Revenue from PCS is classified as 
maintenance and other services and is recognized ratably over the term of the contract, as the Company satisfies the PCS performance obligation over time 
as a stand ready to perform obligation.

Revenue from training, consulting and other services is recognized as the services are performed and is classified as maintenance and other services in the 
consolidated statement of operations. For contracts in which the service consists of a single performance obligation, such as providing a training class to a 
customer, the Company recognizes revenue upon completion of the performance obligation. For service contracts that are longer in duration and often 
include multiple performance obligations (for example, point-in-time training and consulting), the Company measures the progress toward completion of 
the obligations and recognizes revenue accordingly. In measuring progress towards the completion of performance obligations, the Company typically 
utilizes output-based estimates for services with fixed fee arrangements, and estimates output based on the total tasks completed as compared to the total 
tasks required for each contract. Input-based estimates are utilized for services that involve general consultations with contractual billing arrangements 
based on time and materials, utilizing direct labor as the input measure.

The Company also executes arrangements through indirect channel partners in which the channel partners are authorized to market and distribute the 
Company's software products to end users of the Company's products and services in specified territories. In sales facilitated by channel partners, the 
channel partner bears the risk of collection from the end-user customer. The Company recognizes revenue from transactions with channel partners in a 
manner consistent with the direct sales described above for both perpetual and term-based licenses. Revenue from channel partner transactions is the 
amount remitted to the Company by the channel partners. This amount includes a fee for PCS that is compensation for providing technical enhancements 
and the second level of technical support to the end user, which is recognized over the period that PCS is to be provided. The Company does not offer right 
of return, product rotation, or price protection to any of its channel partners.

Non-income related taxes collected from customers and remitted to governmental authorities are recorded on the consolidated balance sheets as accounts 
receivable, net and other accrued expenses and current liabilities. These amounts are reported on a net basis in the consolidated statements of operations 
and do not impact reported revenues or expenses. Certain hardware revenue is included within software revenue and is recognized when all revenue 
recognition criteria stated above are met, which is generally when the products are delivered to end customers.

Software related services

Consulting services from product design and development projects are considered distinct performance obligations and are provided to customers on a 
time-and-materials (“T&M”) or fixed-price basis. The Company recognizes software services revenue for T&M contracts based upon hours worked and 
contractually agreed upon hourly rates using the input method. Revenue from fixed-price engagements is recognized using the output method based on the 
ratio of costs incurred to total estimated project costs.

Client engineering services

Client engineering services revenue are derived from professional services for staffing primarily representing engineers and data scientists located at a 
customer site. These professional services are considered distinct performance obligations and are provided to customers on a T&M basis. The Company 
recognizes this revenue for T&M contracts based upon hours worked and contractually agreed upon hourly rates using the input method. 

Other

Other revenue includes product revenue from the sale of LED products primarily for the replacement of fluorescent tubes. Revenue from the sale of LED 
products is recognized when all revenue recognition criteria stated above are met, which is generally when the products are delivered to resellers or to end 
customers. Sales returns, which reduce revenue, are estimated using historical experience.

Property and equipment, net

Property and equipment are stated at cost, less accumulated depreciation and amortization. Equipment held under capital leases are stated at the present 
value of minimum lease payments less accumulated amortization. Depreciation is calculated using the straight-line method over the estimated useful lives 
of the assets. 

75

 
Table of Contents

Expenditures for maintenance and repairs are charged to expense in the period incurred. Major expenditures for betterments are capitalized when they meet 
the criteria for capitalization. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and 
any resulting gain or loss is reflected in the consolidated statements of operations in the period realized.

Building and improvements are depreciated over an estimated useful life of five to thirty-nine years. Computer equipment and software is depreciated over 
an estimated useful life of three to five years. Office furniture and equipment is depreciated over an estimated useful life of five to fifteen years. Leasehold 
improvements and assets acquired under capital leases are amortized over the lease term or the estimated useful life of the related asset or improvement, 
whichever is shorter.

Software development costs

Software development costs incurred prior to the establishment of technological feasibility are expensed as incurred. Technological feasibility is established 
upon the completion of a detailed program design. Capitalization of software development costs may begin upon the establishment of technological 
feasibility and ends when the product is available for general release. Generally, the time between the establishment of technological feasibility and 
commercial release of software is short. As such, all internal software development costs have been expensed as incurred and included in research and 
development expense in the accompanying consolidated statements of operations.

Impairment of long-lived assets

Long-lived assets, such as property and equipment, and definite-lived intangible assets, including developed technology and customer relationships, are 
reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If 
circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company compares the undiscounted future cash flows 
expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable 
on an undiscounted cash flow basis, an impairment charge is recognized to the extent that the carrying amount exceeds its fair value. Fair value is 
determined through various valuation techniques, including discounted cash flow models and third-party independent appraisals. No impairment losses 
were recognized in 2023, 2022, or 2021.

Goodwill and other indefinite-lived intangible assets

Goodwill represents the excess of the consideration transferred for an acquired entity over the estimated fair values of the net tangible assets and the 
identifiable assets acquired. As described in Note 4 – Acquisitions, the Company has recorded goodwill in connection with certain acquisitions. Goodwill 
and other indefinite-lived intangible assets are not amortized, but rather are reviewed for impairment annually or more frequently if facts or circumstances 
indicate that the carrying value may not be recoverable.

The Company has determined that there is one reporting unit with goodwill subject to goodwill impairment testing. An entity has the option to perform a 
qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount prior to 
performing the quantitative two-step impairment test. 

The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it 
is more likely than not that the fair value of a reporting unit is less than its carrying amount prior to performing the quantitative two-step impairment test. 
The qualitative assessment evaluates various events and circumstances, such as macro-economic conditions, industry and market conditions, cost factors, 
relevant events and financial trends that may impact a reporting unit’s fair value. If, after assessing the totality of events or circumstances, an entity 
determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill, then additional 
impairment testing is not required. However, if an entity concludes otherwise, then it is required to perform the two-step goodwill impairment test.

The impairment test involves comparing the estimated fair value of a reporting unit with its book value, including goodwill. If the estimated fair value 
exceeds book value, goodwill is considered not to be impaired. If, however, the fair value of the reporting unit is less than book value, then an impairment 
loss is recognized in an amount equal to the amount that the book value of the reporting unit exceeds its fair value, not to exceed the total amount of
 goodwill allocated to the reporting unit.

76

 
Table of Contents

The Company performs its annual impairment review of goodwill in the fourth quarter of each year and when a triggering event occurs between annual 
impairment dates. For 2023, the Company performed a qualitative assessment of goodwill and determined that it was not more likely than not that the fair 
value of its reporting unit with goodwill was less than its carrying amount. Accordingly, the Company determined that its goodwill was not impaired.

The Company performs its annual impairment review of indefinite-lived intangibles in the fourth quarter of each year and when a triggering event occurs 
between annual reporting dates. In 2023, the Company performed a qualitative assessment of indefinite-lived trade names and determined there was no 
indication of impairment. Accordingly, no impairment charges were recognized in 2023.

Government assistance

The Company receives incentives from federal, state and local governments in different regions of the world to primarily encourage the Company to 
establish, maintain, or increase investment or employment in the region. Government incentives are recorded in the consolidated financial statements in 
accordance with their purpose as a reduction of expense or other income based on the substance of the incentive received. Benefits are generally recorded 
when the conditions of the grant are met, there is reasonable assurance of receipt and amounts are recorded in earnings as the expenses in which the 
incentive is meant to offset are incurred. For the years ended December 31, 2023 and 2022, respectively, other operating income includes $5.6 million and 
$3.0 million of government related funding.

Receivable for R&D credit

The French government provides a research and development (“R&D”) tax credit known as Credit Impôt Recherche, or CIR, in order to encourage 
Companies to invest in R&D. The tax credit is deductible from the French income tax and any excess is carried forward for three years. After three years, 
any unused credit may be reimbursed to the Company by the French government. As of December 31, 2023, the Company had approximately $12.1 million 
receivables from the French government related to CIR, of which $5.7 million was recorded in Income tax receivable and the remaining $6.4 million was 
recorded in Other long-term assets. As of December 31, 2022, the Company had approximately $10.0 million receivables from the French government 
related to CIR, of which $3.1 million was recorded in Income tax receivable and the remaining $6.9 million was recorded in Other long-term assets. CIR is 
subject to customary audit by the French tax authorities. 

Other Investments

Other investments include non-marketable equity investments in privately held companies, which do not have readily determinable fair values, and in 
which the Company does not have a controlling interest or significant influence. The Company applies the measurement alternative for non-marketable 
equity securities, measuring them at cost, less any impairment. These investments are presented within other long-term assets on our consolidated balance 
sheets and are periodically analyzed to determine whether there are indicators of impairment. 

Income taxes

The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax 
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and 
for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income 
in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and 
liabilities is recognized in income in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes that 
these assets will more likely than not be realized. These deferred tax assets are subject to periodic assessments as to recoverability and if it is determined 
that it is more likely than not that the benefits will not be realized, valuation allowances are recorded which increase the provision for income taxes. In 
making such determination, the Company considers all available positive and negative evidence, including historical taxable income, projected future 
taxable income, the expected timing and reversal of existing temporary differences, ability to carryback losses, and tax planning strategies. If based upon 
the evidence, it is more likely than not that the deferred tax asset will not be realized, a valuation allowance is recorded. A valuation allowance is 
recognized to reduce deferred tax assets to the amount that management believes is more likely than not to be realized.

The Company applies a more-likely-than-not recognition threshold to its accounting for tax uncertainties. The Company reviews all of its tax positions and 
makes determinations as to whether its tax positions are more likely than not to be sustained upon examination by the relevant taxing authorities. Only 
those benefits that have a greater than fifty percent likelihood of being sustained upon 

77

 
Table of Contents

examination by taxing authorities are recognized. Interest and penalties related to uncertain tax positions are recorded in the provision for income taxes in 
the consolidated statements of operations.

Research and development costs

Research and development costs are expensed as incurred. Research and development expenses consist primarily of salaries and benefits of research and 
development employees and costs incurred related to the development of new software products and significant enhancements and engineering changes to 
existing software products. 

Advertising costs

Advertising costs are expensed as incurred. Advertising expenses were $5.1 million, $5.0 million and $4.3 million for the years ended December 31, 2023, 
2022 and 2021, respectively.

Assets held for sale

Assets held for sale are reported at the lower of the carrying amount or fair value less costs to sell. Depreciation expense is not recognized on assets held for 
sale. As of December 31, 2022, an office building in Korea and related assets of $2.7 million were classified as held for sale and presented in Prepaid 
expenses and other current assets. The sale of the building was finalized in February 2023.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current 
portion of operating lease liabilities, and operating lease liabilities, net of current portion on the Company’s consolidated balance sheets.     

Stock-based compensation

Employee stock-based awards, consisting of stock options, restricted stock units (RSUs) and employee stock purchase plan (ESPP) shares expected to be 
settled by issuing shares of Class A common stock, are recorded as equity awards. The fair value of stock options and ESPP shares on the date of grant is 
measured using the Black-Scholes option pricing model. The Company expenses the grant date fair value of its time-vested stock options subject to graded 
vesting using the straight-line method over the applicable service period. The Company expenses the fair value of ESPP shares over the offering period. 
The fair value of RSUs is measured using the fair value of the Company’s Class A common stock on the date of the grant. The fair value of RSUs is 
recognized as expense on a straight-line basis over the requisite service period, which is generally four years.

Business combinations

The Company accounts for business acquisitions using the acquisition method of accounting. The fair value of purchase consideration of the acquired 
businesses is allocated to the identifiable tangible and intangible assets acquired and liabilities assumed in the transaction based upon their estimated fair 
values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. During the measurement period, which 
may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding 
offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever 
comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Recent accounting guidance

Accounting standards not yet adopted 

78

 
Table of Contents

Reference Rate Reform – In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04 
Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients 
and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or 
another rate that is expected to be discontinued. The amendments in the guidance are optional and effective for all entities as of March 12, 2020 through 
December 31, 2022. In October 2022, the FASB Board voted to amend the sunset date of ASU 2020-04 to December 31, 2024. The Company is currently 
evaluating the impact of this new guidance on its consolidated financial statements and related disclosures and does not expect this guidance to have a 
material effect on its consolidated financial statements.

Segment Reporting – In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable Segment 
Disclosures. The update is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant 
expenses. The ASU requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (CODM), 
a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding 
how to allocate resources. The ASU also requires all annual disclosures currently required by Topic 280 to be included in interim periods. The update is 
effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early 
adoption permitted and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the 
impact of adopting the updated standard.

Income Taxes – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which updates 
income tax disclosures related to the tax rate reconciliation and requires disclosure of income taxes paid by jurisdiction. The amendments are effective for 
fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied prospectively; however, retrospective 
application is permitted. The Company is currently evaluating this ASU to determine the effect on its related disclosures.

3. Revenue from contracts with customers 

Significant judgments

Software revenue

The Company’s contracts with customers typically include promises to transfer licenses and services to a customer. Judgment is required to determine if the 
promises are separate performance obligations within the context of the arrangement, and if so, the allocation of the transaction price to each performance 
obligation. The Company’s determination of standalone selling price for performance obligations is based on the midpoint of the range of historical 
observable prices for goods and services sold separately. In addition, the Company estimates the standalone selling price for certain performance 
obligations where observable prices are not directly available, or a significant portion of historical prices are not within the range. In instances where 
standalone selling price was not determined based on the range of historical observable prices for goods and services sold separately, the Company used an 
adjusted market assessment approach to estimate the standalone selling price. In such cases the Company has considered market conditions and other 
observable inputs, such as internal price lists, peer data, and industry data for a similar or identical product or service. The Company estimates standalone 
selling price at contract inception considering all information that is reasonably available and is based on the amount of consideration for which the 
Company expects to be entitled in exchange for transferring the promised good or service to the customer. The corresponding revenues are recognized as 
the related performance obligations are satisfied.

The Company’s contracts do not include a significant financing component requiring adjustment to the transaction price. Payment terms vary by contract 
type; however, arrangements typically stipulate a requirement for the customer to pay within 30 to 60 days.

The Company rarely enters into agreements to modify previously executed contracts, which constitute contract modifications. The Company assesses each 
of these contract modifications to determine (i) if the additional products and services are distinct from the products and services in the original 
arrangement; and (ii) if the amount of consideration expected for the added products and services reflects the stand-alone selling price of those products and 
services, as adjusted for contract-specific circumstances. A contract modification meeting both criteria is accounted for as a separate contract. A contract 
modification not meeting both criteria is considered a change to the original contract and is accounted for on either (i) a prospective basis as a termination 
of the existing contract and the creation of a new contract; or (ii) a cumulative catch-up basis. Generally, the Company’s contract modifications meet both 
criteria and are accounted for as a separate contract, as adjusted for contract-specific circumstances.

 The Company derived approximately 13.6%, 13.9% and 12.0% of its total revenue through indirect sales channels for the years ended December 31, 2023, 
2022 and 2021, respectively.  

Costs to obtain a contract

The Company pays commissions for new software product and PCS sales as well as for renewals of existing software and PCS contracts. Commissions 
paid to obtain renewal contracts are not commensurate with the commissions paid for new product sales and therefore, a portion of the commissions paid 
for new contracts relate to future renewals.

The Company accounts for new product sales commissions using a portfolio approach and allocates the cost of commissions in proportion to the allocation 
of the transaction price of license and PCS performance obligations. Commissions allocated to the license and license renewal components are expensed at 
the time the license revenue is recognized. Commissions allocated to PCS are capitalized and amortized on a straight-line basis over a period of four years, 
reflecting the Company’s estimate of the expected period that it will benefit from those commissions. As of December 31, 2023 and 2022, respectively, 
capitalized costs to obtain a contract were $4.3 million and $3.9 million recorded in Prepaid and other current assets and $0.9 million and $0.4 million 
recorded in Other long-term assets. Sales commissions were $8.8 million and $8.3 million for the years ended December 31, 2023 and 2022, respectively, 
and were included in Sales and marketing expense in the Company’s consolidated statements of operations.

Contract assets

As of December 31, 2023 and 2022, respectively, contract assets were $5.2 million and $6.3 million included in Accounts receivable and $2.7 million and 
$2.3 million included in Prepaid expenses and other current assets in the Company's consolidated balance sheets.

Deferred revenue

Deferred revenue consists of billings made or payments received in advance of revenue recognition from software license, PCS and professional services 
agreements. The timing of revenue recognition may differ from the timing of billings to customers. Payment terms vary by the type and location of 
customer and the products or services offered. The term between invoicing and when payment is due is not significant. The Company generally invoices its 
customers annually for the forthcoming year of software licenses, and more frequently for other products and services. Accordingly, the Company’s 
deferred revenue balance does not include revenue for future years of multiple year non-cancellable contracts that have not yet been billed. 

Approximately $106.9 million of revenue recognized during 2023 was included in the deferred revenue balances at the beginning of the year. 

Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue 
and amounts that will be invoiced and recognized as revenue in future periods. Contracted revenue not yet recognized was $251.8 million as of December 
31, 2023, of which the Company expects to recognize approximately 66% over the next 12 months and the remainder thereafter.

4. Acquisitions 

2023 Acquisitions

During the year ended December 31, 2023, the Company completed a business acquisition that was insignificant to the Company’s consolidated financial 
statements. The preliminary aggregate purchase price of this acquisition was $6.1 million and was allocated to assets acquired and liabilities assumed at 
their estimated fair values. The allocation included $2.2 million to developed technology, $0.4 million to customer relationships and $2.9 million to 
goodwill, which is deductible for tax purposes. The operating results of this acquisition have been included in the consolidated financial statements since 
the acquisition date. All goodwill is recorded in the Software segment. The Company expects to finalize the purchase accounting as soon as practicable, but 
not later than one year from the acquisition date. The Company’s transaction costs related to the acquisition were not material. 

Prior acquisitions

The Company finalized the valuation of all 2022 acquisitions as of December 31, 2023. There were no significant changes to the preliminary fair value of 
assets acquired and liabilities assumed, as previously reported. 

The Company recognized a $5.7 million loss and a $7.2 million gain, respectively, for the years ended December 31, 2023 and 2022, from a mark-to-
market adjustment of contingent consideration associated with the World Programming acquisition. The mark-to-market adjustments were included in 
Other operating expense (income), net in the consolidated statements of operations. 

As of December 31, 2022, the Company had a $12.0 million contingent consideration liability related to the World Programming acquisition. The Company 
settled the liability in October 2023 by issuing 257,382 shares of its Class A common stock in accordance with the acquisition agreement.

5. Supplementary Information

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with original or remaining maturities of 90 days or less at the date of purchase to be cash equivalents. 
Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash is included in Other long-term assets on the consolidated 
balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets that

In June 2022, the Company issued $230.0 million aggregate principal amount of 1.750% convertible senior notes due in 2027 (the "2027 Notes"), which 
includes the initial purchaser’s exercise in full of its option to purchase an additional $30.0 million principal amount of the 2027 Notes, in a private 
offering. The net proceeds from the issuance of the 2027 Notes was $224.3 million after deducting discounts, commissions and estimated issuance costs.

The Company entered into an Indenture relating to the issuance of the 2027 Notes dated June 14, 2022 (the “Indenture”), by and between the Company and 
U.S. Bank Trust Company, National Association, as trustee. The Indenture includes customary covenants and sets forth certain events of default after which

types of bankruptcy or insolvency events of default involving the Company after which the 2027 Notes become automatically due and payable. The 2027 
Notes are senior unsecured obligations of the Company.

The 2027 Notes mature on June 15, 2027, unless earlier repurchased, redeemed or converted. The Company may redeem for cash all or, subject to certain 
limitations, any portion of the 2027 Notes, at its option, on or after June 20, 2025 if the last reported sale price of Altair's Class A Common Stock has been 
at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period, 
at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption 
date. The 2027 Notes bear interest at a rate of 1.750% per year, payable semiannually in arrears on June 15 and December 15 of each year, which 
commenced on December 15, 2022.  

The 2027 Notes have an initial conversion rate of 13.9505 shares of the Company's Class A common stock per $1,000 principal amount of 2027 Notes, 
which is equivalent to an initial conversion price of approximately $71.68 per share of Class A common stock. The conversion rate will be subject to 
adjustment upon the occurrence of certain events specified in the Indenture but will not be adjusted for any accrued and unpaid interest. In addition, upon 
the occurrence of a make whole fundamental change or a redemption period (each as defined in the Indenture), the Company will, in certain circumstances, 
increase the conversion rate by a specified number of additional shares for a holder who elects to convert its 2027 Notes in connection with such make 
whole fundamental change or during the relevant redemption period.

Holders of the 2027 Notes may convert all or any portion of their 2027 Notes at any time prior to the close of business on the business day immediately 
preceding December 15, 2026, in integral multiples of $1,000 principal amount, only under the following circumstances:

•

•

•

•

during any calendar quarter, if the last reported sale price of the Class A Common Stock for at least 20 trading days (whether or not 
consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding 
calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;  

during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as 
defined in the Indenture) per $1,000 principal amount of the 2027 Notes for each trading day of the measurement period was less than 98% of 
the product of the last reported sale price of the Class A Common Stock and the conversion rate on each such trading day;  

if the Company calls the 2027 Notes for redemption (which the Company may not do prior to June 20, 2025), at any time prior to the close of 
business on the scheduled trading day immediately preceding the redemption date but only with respect to the 2027 Notes called (or deemed 
called) for redemption; or 

upon the occurrence of specified corporate events. 

On or after December 15, 2026 until the close of business on the business day immediately preceding the maturity date, holders may convert their 2027 
Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Class 
A Common Stock or a combination of cash and shares of the Class A Common Stock, at the Company’s election, in the manner and subject to the terms 
and conditions provided in the Indenture. 

During the period ended December 31, 2023, the conditions allowing holders of the 2027 Notes to convert were not met. Therefore, the 2027 Notes were 
classified as long-term debt on the consolidated balance sheet as of December 31, 2023.

As of December 31, 2023, the “if converted value” of the 2027 Notes exceeded the principal amount by $40.0 million.

2024 Notes

In June 2019, the Company issued $230.0 million aggregate principal amount of 0.25% convertible senior notes maturing on June 1, 2024 (the "2024 
Notes" together with the 2027 Notes "Convertible Notes"), which includes the underwriters’ exercise in full of their option to purchase an additional $30.0 
million principal amount of the 2024 Notes, in a public offering. The net proceeds from the issuance of the 2024 Notes were $221.9 million after deducting 
the underwriting discounts and commissions and issuance costs. The 2024 Notes have an initial conversion rate of 21.5049 shares of the Company's Class 
A common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $46.50 per share of its 
Class A common stock. The interest rate is fixed at 0.25% per year, payable semi-annually in arrears on June 1 and December 1 of each year, which 
commenced on December 1, 2019. The 2024 Notes mature on June 1, 2024, unless, earlier repurchased or redeemed by the Company or converted pursuant 
to their terms.

Prior to January 1, 2022, the Company separated the 2024 Notes into liability and equity components. On issuance, the carrying amount of the equity 
component was recorded as a debt discount and subsequently amortized to interest expense. Effective January 1, 2022, the Company adopted ASU 2020-06 
using the modified retrospective approach. As a result, the 2024 Notes are accounted for as a single liability measured at amortized cost, as no other 
embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in a decrease to Accumulated deficit of $23.9 
million, a decrease to Additional paid-in capital of $50.0 million, and an increase to Convertible senior notes, net of $26.1 million.

During the year ended December 31, 2022, using proceeds from the issuance of the 2027 Notes, the Company entered into separate privately negotiated 
transactions with certain holders of the 2024 Notes to repurchase and retire $148.2 million aggregate principal amount of the 2024 Notes for an aggregate 
amount of $192.4 million of cash including accrued and unpaid interest. The Company recognized expense of $16.6 million, representing the fair value of 
the consideration paid to certain holders of the 2024 Notes in excess of the value to which they were entitled to receive on the respective settlement dates. 
The amount is included in Other expense, net in the Company’s consolidated statement of operations. 

As of December 31, 2023, until the close of business on the business day immediately preceding the maturity date, holders may convert their 2024 Notes at 
any time. Upon conversion, the Company has elected to settle the 2024 Notes par value in cash and to settle the premium in shares of Class A common 
stock, subject to the terms and conditions provided in the Indenture. As of December 31, 2023, $81.7 million principal amount of the 2024 Notes remained 
outstanding and were classified as current liabilities on the consolidated balance sheet.

As of December 31, 2023, the “if converted value” of the 2024 Notes exceeded the principal amount by $66.2 million.

On November 7, 2022, the Company exercised the $50.0 million accordion feature of its credit facility in accordance with the terms and conditions set forth 
in its credit agreement. In June 2022, the Company amended its credit agreement to, among other things, permit the issuance of the 2027 Notes and extend 
the maturity date of the credit facility to December 31, 2025. 

As of December 31, 2023, the Company has a $200.0 million credit agreement with a maturity date of December 31, 2025 (“2019 Amended Credit 
Agreement”) and there were no outstanding borrowings. The 2019 Amended Credit Agreement is available for general corporate purposes, including 
working capital, capital expenditures, and permitted acquisitions.

Borrowings under the 2019 Amended Credit Agreement bear interest at a rate per annum equal to an agreed upon applicable margin plus, at the Company’s 
option, either the Alternate Base Rate (defined as the greatest of (1) the Prime Rate (as defined in the 2019 Amended Credit Agreement) in effect on such 
day, (2) the Federal Funds Effective Rate (as defined in the 2019 Amended Credit Agreement) in effect on such day plus 1/2 of 1.00% and (3) the Adjusted 
Term SOFR Rate (as defined in the 2019 Amended Credit Agreement) for one-month interest period as published two U.S. Government Securities Business 
Days prior to such day (or if such day is not a business day, the immediately preceding business day) plus 1.00%) or the Adjusted Term SOFR Rate. The

Table of Contents

margin for borrowings under the 2019 Amended Credit Agreement is based on the Company’s most recently tested senior secured leverage ratio and will 
vary from (a) in the case of Term Benchmark loans, 1.25% to 2.00%, and (b) in the case of ABR loans or swingline loans, 0.25% to 1.00%. The Company 
pays a commitment fee ranging from 0.15% to 0.30% on the unused portion of the 2019 Amended Credit Agreement. 

Collateral and guarantees

The 2019 Amended Credit Agreement is secured by collateral including (i) substantially all of the Company’s properties and assets, and the properties and 
assets of the Company’s domestic subsidiaries but excluding any patents, copyrights, patent applications or copyright applications or any trade secrets or 
software products and (ii) pledges of the equity interests in all present and future domestic subsidiaries (subject to certain exceptions as provided for under 
the 2019 Amended Credit Agreement). The Company’s direct and indirect domestic subsidiaries are guarantors of all the obligations under the 2019 
Amended Credit Agreement.

Debt covenants

The 2019 Amended Credit Agreement requires the Company to maintain a Senior Secured Leverage Ratio not greater than 3.00 to 1.00 as of the last day of 
each fiscal quarter. The Senior Secured Leverage Ratio is defined as the ratio of total indebtedness secured by a lien (net of unrestricted domestic cash in 
excess of $20.0 million) to EBITDA, as such terms are defined in the 2019 Amended Credit Agreement, for the rolling four quarter period ending on such 
date. As of December 31, 2023, the Company was in compliance with its financial covenants.

Other

The Company has available overdraft and line of credit facilities in several countries in which it operates. These credit facilities are with various domestic 
and international banks and are at quoted market rates. As of December 31, 2023 and 2022, the Company had $2.4 million and $3.1 million, respectively, of 
availability under these facilities and there were no outstanding commitments.

8. Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease assets and operating lease obligations 
on the Company’s consolidated balance sheets. 

Right of use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s 
obligation to make lease payments under the lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of 
the future minimum lease payments over the lease term at commencement date. At commencement date, the ROU asset also includes adjustments for lease 
prepayments, lease incentives received and the lessee's initial direct costs, if applicable. As most of the Company’s leases do not provide an implicit rate, 
the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future 
payments. The incremental borrowing rates are determined using rates specific to the term of the lease, economic environments where lease activity is 
concentrated, value of lease portfolio, and assuming full collateralization of the loans. Subsequent to the commencement date, the operating ROU asset is 
equal to the remeasured lease liability adjusted for cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, 
unamortized lease incentives, unamortized initial direct costs and any impairment of the ROU assets. The lease terms may include options to extend or 
terminate the lease when it is reasonably certain that the Company will exercise that option. Lease cost for minimum lease payments is recognized on a 
straight-line basis over the lease term.

The Company does not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease 
and non-lease components, the Company does not allocate the contract consideration, and accounts for the lease and non-lease components as a single lease 
component.

The Company’s operating leases consist of office facilities, office equipment and cars. The Company’s leases have remaining terms of less than one year to 
15 years, some of which include one or more options to renew and some of which include options to terminate the leases within the next three years. The 
Company does not have any finance leases as of December 31, 2023.

Operating lease cost was $13.1 million, $13.4 million and $13.8 million for the years ended December 31, 2023, 2022 and 2021, respectively. Operating 
lease cost includes short-term leases and variable lease costs, which are immaterial. Rent cost related to operating leases for office facilities was $11.3 
million, $11.7 million and $12.2 million for the years ended December 31, 2023, 2022 and 2021, respectively.

The accounting guidance for fair value, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands 
disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the price 
that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. 
The framework for measuring fair value consists of a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair 
value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while 
unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly 
summarized as follows:

Level 1— Quoted prices in active markets for identical assets and liabilities at the measurement date;

Level 2— Observable inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3— Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair 
value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short maturities. Interest on 
the Company’s line of credit is at a variable rate, and as such the debt obligation outstanding approximates fair value.

The carrying value of the Company’s Convertible Notes are at face value less unamortized debt issuance costs. The estimated fair values of the Convertible 
Notes, which the Company has classified as Level 2 financial instruments, were determined based on quoted bid prices of the Convertible Notes on the last 
trading day of each reporting period. As of December 31, 2023, the estimated fair value of the 2027 Notes and 2024 Notes was $297.6 million and $147.6 
million, respectively, and is presented for required disclosure purposes only. For further information on the Convertible Notes see Note 7. 

10. Stockholders’ equity

Preferred stock

As of December 31, 2023, the Company had authorized 45,000,000 shares of preferred stock, par value $0.0001, of which no shares were issued or 
outstanding. The Board of Directors has the authority to issue the preferred stock in one or more series and to fix rights, preferences, privileges, and 
restrictions, including dividends and the number of shares constituting any series or the designation of such series, without any further vote or action by the 
stockholders.

Common stock

As of December 31, 2023, the Company had authorized 513,796,572 shares of Class A common stock, par value $0.0001, and 41,203,428 shares of Class B 
common stock, par value $0.0001. The rights of the holders of Class A common stock and Class B common stock are identical, except with respect to 
voting and conversion rights. Each share of Class A common stock is entitled to one vote per share. Each share of Class B common stock is entitled to ten 
votes per share and is convertible into one share of Class A common stock.

The holders of Class A and Class B common stock are entitled to dividends at the sole discretion of the Board of Directors. No common stock dividends 
were declared or paid in 2023, 2022, or 2021.

Stock repurchase program

In May 2023, the Company’s Board of Directors approved an increase under our existing stock repurchase program from $50.0 million to $75.0 million of 
the Company's outstanding Class A Common Stock. As permitted by securities laws and other legal requirements and subject to market conditions and 
other factors, purchases under the program may be made from time to time in the open market at prevailing prices, or through privately negotiated 
transactions. The Company is not obligated to repurchase any dollar amount or number of shares, and the stock repurchase program may be suspended or 
terminated at any time. All shares repurchased under the stock repurchase program are retired. The Company intends to use the share repurchase plan to 
opportunistically return capital to shareholders while still focusing on its primary goal of investing in the business to drive growth.

During the year ended December 31, 2023, under the Company's stock repurchase program, the Company repurchased 91,273 shares at an average price of 
$46.63 per share for a total cost of $4.3 million. As of December 31, 2022, $49.1 million of shares of Class A Common Stock remained available for 
repurchase under the program. 

11. Stock-based compensation

2001 stock-based compensation plans

Nonqualified stock option plan

In 2001, the Company established the Nonqualified Stock Option Plan (“NSO Plan”) under which 994,884 stock options with an exercise price of $.000025 
remain outstanding as of December 31, 2023. The NSO Plan was terminated in 2003. Stock options under the NSO plan were immediately vested and have 
a contractual term of 35 years from the date of grant. The outstanding awards will continue to be governed by their existing terms under the NSO Plan. The 
NSO Plan is accounted for as an equity plan.

2012 stock-based compensation plans

During 2012, the Company established the 2012 Incentive and Nonqualified Stock Option Plan (“2012 Plan”) which permits the issuance of 5,200,000 
shares of Class A common stock for the grant of nonqualified stock options (“NQSO”) and incentive stock options (“ISO”) for management, other 
employees, and board members of the Company. The options are issued at a price equal to or greater than fair market value at date of grant. All options 
have a contractual term of 10 years from date of grant.

The 2012 Plan is accounted for as an equity plan. For those options expected to vest, compensation expense is recognized on a straight-line basis over a 
four-year period, the total requisite service period of the awards.

2017 stock-based compensation plan

In 2017, the Company’s board of directors adopted the 2017 Equity Incentive Plan (“2017 Plan”), which was approved by the Company’s stockholders. The 
2017 Plan provides for the grant of incentive stock options to the Company’s employees and any parent and subsidiary corporations’ employees, and for the 
grant of nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, performance shares, other cash-
based and stock-based awards to the Company’s employees, directors and consultants and the Company’s parent, subsidiary, and affiliate corporations’ 
employees and consultants. The 2017 Plan has 16,999,318 authorized shares of the Company’s Class A common stock reserved for issuance. As of 
December 31, 2023, the Company had 4,965,437 shares of its common stock available for future issuances under the 2017 Plan.

Fair value of equity awards

The Company measures the fair value of its stock options on the date of grant using the Black-Scholes option pricing model. This valuation model requires 
the Company to make certain estimates and assumptions, including assumptions related to the expected price volatility of the Company’s stock, the period 
under which the options will be outstanding, the rate of return on risk-free investments, and the expected dividend yield for the Company’s stock.

The fair values of the Company’s stock options granted during the year ended December 31, 2023, 2022 and 2021, were estimated using the following 
assumptions: 

Weighted average grant date fair value per share
Expected volatility
Expected term (in years)
Risk-free interest rate
Expected dividend yield

These assumptions and estimates are as follows:

2023 grants
$65.19 - 67.65  
35%  
6.25  
3.5% - 4.3%

Fair Value of Common Stock. The Company used the publicly quoted price as reported on the Nasdaq Global Select Market as the fair value of 
its common stock.

Expected Term. The Company used the simplified method to determine the expected term.

Risk-Free Interest Rate. The Company based the risk-free interest rate on U.S. Treasury zero-coupon yield curves with a remaining term equal to 
the expected term of the option.

Expected Volatility. As the Company does not have an extensive trading history for its common stock, the expected volatility was derived using 
the historical volatility of the returns of comparable publicly traded companies combined with the brief trading history of the Company’s 
common stock. 

2021 Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (“ESPP”) which allows eligible employees to purchase shares of common stock through payroll 
deductions. As of December 31, 2023, the Company had 2,832,220 shares of its common stock available for future issuances under the ESPP.

Table of Contents

The purchase price for each share of common stock purchased under the ESPP will be 85% of the lower of (a) the fair market value per share on the first 
day of the applicable offering period or (b) the fair market value per share on the applicable purchase date.

Each offering period will last a number of months determined by the plan administrator, up to a maximum of 27 months. The initial offering period began 
on July 15, 2021, and ended on January 14, 2022, and new offering periods are expected to begin on each January 15 and July 15 thereafter, unless 
modified by the plan administrator. The ESPP allows participants to purchase the Company’s common stock through payroll deductions, up to a maximum 
of 15% of their eligible compensation or $25,000, whichever is lower, and subject to limitations under Section 423 of the Internal Revenue Code. The plan 
administrator has limited participant contributions to $1,000 per month to prevent prejudicial advantages to higher compensated employees. Participants 
may withdraw from the ESPP and receive a refund of their accumulated payroll contributions at any time prior to a purchase date.

The Company issued 182,883 shares and 184,897 shares of common stock under the ESPP during the years ended December 31, 2023 and 2022, 
respectively. There were no issuances of common stock under the ESPP during the year ended December 31, 2021. As of December 31, 2023 and 2022, 
$4.2 million and $4.0 million, respectively, has been withheld on behalf of employees for future purchases under the ESPP due to the timing of payroll 
deductions and was reported in current liabilities. The Company recognized $2.4 million, $2.6 million and $1.2 million of stock-based compensation 
expense related to the ESPP for the years ended December 31, 2023, 2022, and 2021, respectively.

Other

In connection with the acquisition of World Programming in December 2021, per the World Programming stock purchase agreement, $29.5 million of the 
Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The 
accounting treatment for these shares in the context of the business combination was to recognize the expense as a post-combination expense, not as 
transaction consideration.

The estimated post combination expense to the Company as a result of the World Programming business combination was approximately $29.5 million 
which is recognized on an accelerated method over the employment period. As of December 31, 2023, the weighted average remaining service period was 
1.0 year. Once the vesting conditions of the service period are met, the Company will issue shares for each award. Stock-based compensation expense 
includes $8.0 million, $17.6 million and $0.7 million for the years ended December 31, 2023, 2022 and 2021, respectively.

In connection with the acquisition of Powersim Inc. in March 2022, per the Powersim stock purchase agreement, 68,792 shares of the Company’s Class A 
Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares will be issued in 
installments of 34,396 shares on the one- and two-year anniversaries of the closing, subject to potential reduction in certain circumstances. The accounting 
treatment for these shares in the context of the business combination was to recognize the expense as a post-combination expense, not as transaction 
consideration. The post combination expense was determined to have a fair value of approximately $4.3 million and is recognized on an accelerated method 
over the employment period. As of December 31, 2023, the weighted average remaining service period was 0.2 years. Stock-based compensation expense 
includes $1.4 million and $2.7 million for the years ended December 31, 2023 and 2022, respectively.

In connection with the acquisition of Concept Engineering in June 2022, per the Concept Engineering stock purchase agreement, 105,082 shares of the 
Company’s Class A Common Stock will be issued to existing employees, subject to continuing employment and certain other contingencies. The shares 
will be issued in installments of 52,541 shares on the one- and two-year anniversaries of the closing, subject to potential reduction in certain circumstances. 
The accounting treatment for these shares in the context of the business combination was to recognize the expense as a post-combination expense, not as 
transaction consideration. The post combination expense was determined to have a fair value of approximately $6.0 million and is recognized on an 
accelerated method over the employment period. As of December 31, 2023, the weighted average remaining service period was 0.4 years. Stock-based 
compensation expense includes $2.6 million and $2.7 million for the years ended December 31, 2023 and 2022, respectively.

The Tax Cuts and Jobs Act, or the Tax Act, subjects a U.S. shareholder to current tax on global intangible low-taxed income (“GILTI”) earned by certain 
foreign subsidiaries. The impact of GILTI resulted in no incremental tax expense for the years ended December 31, 2023, 2022 and 2021 due to a full 
valuation allowance on U.S. net deferred tax assets. In addition, the Company has made an accounting policy election to treat taxes due under the GILTI 
provision as a current period expense.

Deferred income tax assets and liabilities result from differences in the basis of assets and liabilities for tax and financial statements purposes. The 
approximate tax effect of each type of temporary difference, and operating losses and tax credit carryforwards that give rise to a significant portion of the 
deferred tax assets and liabilities are as follows (in thousands):

Reflects gross amount before jurisdictional netting of deferred tax assets and liabilities.

Deferred tax assets and liabilities are determined separately for each tax jurisdiction on a separate or on a consolidated tax filing basis, as applicable, in 
which the Company conducts its operations or otherwise incurs taxable income or losses. A valuation allowance is

recorded when it is more likely than not that some portion or all of the gross deferred tax assets will not be realized. The realization of deferred tax assets 
depends on the ability to generate sufficient taxable income of the appropriate character within the carryback or carryforward periods provided for in the 
tax law for each applicable tax jurisdiction. The Company considers the following possible sources of taxable income when assessing the realization of 
deferred tax assets:

•

•

•

•

taxable income in prior carryback years;

future reversals of existing taxable temporary differences;

future taxable income exclusive of reversing temporary differences and carryforwards; and

prudent and feasible tax planning strategies that the Company would be willing to undertake to prevent a deferred tax asset from otherwise 
expiring.

The assessment regarding whether a valuation allowance is required or whether a change in judgment regarding the valuation allowance has occurred also 
considers all available positive and negative evidence, including but not limited to:

•

•

•

•

•

nature, frequency, and severity of cumulative losses in recent years;

duration of statutory carryforward and carryback periods;

statutory limitations against utilization of tax attribute carryforwards against taxable income;

historical experience with tax attributes expiring unused; and

near‑ and medium‑term financial outlook.

The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. Accordingly, it 
is generally difficult to conclude a valuation allowance is not required when there is significant objective and verifiable negative evidence, such as 
cumulative losses in recent years. The Company uses the actual results for the last two years and current year results as the primary measure of cumulative 
losses in recent years.

The evaluation of deferred tax assets requires judgment in assessing the likely future tax consequences of events recognized in the financial statements or 
tax returns and future profitability. The recognition of deferred tax assets represents the Company’s best estimate of those future events. Changes in the 
current estimates, due to unanticipated events or otherwise, could have a material effect on the Company’s results of operations and financial condition.

In certain tax jurisdictions, the Company’s analysis indicates that it has cumulative losses in recent years. This is considered significant negative evidence, 
which is objective and verifiable and, therefore, difficult to overcome. However, the cumulative loss position is not solely determinative and, accordingly, 
the Company considers all other available positive and negative evidence in its analysis. Based on its analysis, the Company has recorded a valuation 
allowance for the portion of deferred tax assets where based on the weight of available evidence it is unlikely to realize those deferred tax assets.

Based on the evidence available including a lack of sustainable earnings, the Company in its judgment previously recorded a valuation allowance against 
substantially all of its net deferred tax assets in the United States. If a change in judgment regarding this valuation allowance were to occur in the future, the 
Company will record a potentially material deferred tax benefit, which could result in a favorable impact on the effective tax rate in that period.   

The Company continues to record deferred foreign taxes on gross book-tax basis differences to the extent of foreign distributable reserves and excess cash 
balances for its subsidiary in India. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings is 
not practicable.

The change in valuation allowance in Other for 2023 of $0.5 million is primarily related to currency translation. The change in the valuation allowance in 
Other for 2022 of $21.6 million is primarily related to a $6.8 million increase from the adoption of ASU 2020-06 for convertible debt instruments, and a 
$13.1 million valuation allowance recorded on deferred tax assets established during purchase accounting from the RapidMiner acquisition. The change in 
valuation allowance in Other for 2021 of $2.9 million is primarily related to a valuation allowance recorded on deferred tax assets established during

As of December 31, 2023, the Company had $15.0 million of gross unrecognized tax benefits that if recognized would affect the effective tax rate. The 
Company expects a reduction over the next 12 months in the gross unrecognized tax benefits of approximately $0.5 million which if recognized would not 
impact the effective tax rate during 2024.

The Company operates globally but considers its more significant tax jurisdictions to include the United States, India, Germany, Japan, and China. India 
has tax years open for examination from 2011 through 2023. All other significant jurisdictions have open tax years from 2016 through 2023.

The Company records interest and penalties with respect to unrecognized tax benefits as a component of the provision for income taxes. For the years 
ended December 31, 2023, 2022, and 2021, accrued interest and penalties related to unrecognized tax benefits were approximately $1.2 million, $1.0 
million, and $1.0 million, respectively, all of which if recognized would affect the effective tax rate.

13. Net loss per share

The Company adopted ASU 2020-06 on January 1, 2022, using the modified retrospective method, applicable to its convertible senior notes outstanding as 
of adoption. The Company has not changed any previously disclosed amounts or provided additional disclosures for comparative periods. ASU 2020-06 
requires the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. Under the if-converted method, 
shares related to convertible senior notes, to the extent dilutive, are assumed to be converted into common stock at the beginning of the period.

Basic net (loss) income per share attributable to common stockholders is computed using the weighted average number of shares of common stock 
outstanding for the period, excluding dilutive securities, stock options, RSUs and ESPP shares. Diluted net (loss) income per share attributable to common 
stockholders is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares. 
The treasury stock method is used to calculate the effect of dilutive securities, stock options, RSUs and ESPP shares and the if-converted method is used to 
calculate the effect of convertible instruments.

Since the Company was in a net loss position for the years ended December 31, 2023, 2022 and 2021, basic net loss per share attributable to common 
stockholders is the same as diluted net loss per share for those periods as the inclusion of all potential common shares outstanding would have been anti-
dilutive. 

14. Retirement benefits

The Company sponsors a 401(k)-profit sharing plan (the “Plan”) for all eligible U.S. employees. This Plan allows eligible employees to contribute up to 
80% of their compensation to the Plan. The Company makes discretionary matching contributions to the Plan provided the employee is employed on the 
last day of the year. Such discretionary contributions vest ratably over five years of service. The Company’s contributions to the Plan were $1.6 million for 
each of the years ended December 31, 2023, 2022 and 2021.

The Company also participates in government-mandated retirement and/or termination indemnity plans, benefiting certain non-U.S. employees. 
Termination benefits are generally lump sum payments based upon an individual’s years of credited service and annual salary at retirement. These plans are 
generally unfunded, and employees receive payments at the time of retirement or termination under applicable labor laws or agreements. The amount of net 
benefit cost recorded in the consolidated statements of operations for these plans was $2.6 million, $2.5 million and $3.0 million in 2023, 2022 and 2021, 
respectively. The amount of benefits paid under these plans was $0.4 million, $0.7 million and $0.4 million in 2023, 2022 and 2021, respectively. The 
accumulated benefit obligation, unlike the projected benefit obligation, does not reflect expected benefit increases from future salary levels, and was $11.6 
million and $10.1 million as of December 31, 2023 and 2022, respectively, under these plans. The projected benefit obligation, net of plan assets, was $16.8 
million and $13.1 million as of December 31, 2023 and 2022, respectively.

The Company acquired World Programming Limited and a related company (collectively, “World Programming”) in December 2021. 

In 2018, SAS Institute, Inc. (“SAS”) filed litigation in the United States District Court for the Eastern District of Texas (the “Texas Court”) asserting that 
World Programming infringed SAS copyrights and patents. SAS voluntarily dismissed with prejudice its patent claims, and the Texas Court entered 
judgment in favor of World Programming on the copyright claims. SAS appealed the Texas Court judgment to the United States Court of Appeals for the 
Federal Circuit (the “Court of Appeals”). Oral arguments were held before the Court of Appeal on January 13, 2022. On April 6, 2023, the Court of 
Appeals issued its decision in favor of World Programming by affirming the Texas Court’s dismissal of SAS’s copyright claims. On September 3, 2023, the 
Company was notified that SAS elected not to file its petition for a writ of certiorari within the period in which SAS was eligible to file such petition. With 
such period having expired, the judgment of the Texas Court in favor of World Programming is now final and closed.

Legal proceedings

From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. The Company has received, and may in 
the future continue to receive, claims from third parties asserting, among other things, infringement of their intellectual property rights. Future litigation

Effects of proceedings

The results of any current or future litigation cannot be predicted with certainty and regardless of the outcome, litigation can have an adverse impact on the 
Company because of defense and settlement costs, diversion of management resources and other factors.

Commitments

The Company defines its operating segments as components of its business where separate financial information is available and used by the chief 
operating decision maker (“CODM”) in deciding how to allocate resources to its segments and in assessing performance. The Company’s CODM is its 
Chief Executive Officer.

The Company has identified two reportable segments for financial reporting purposes: Software and Client Engineering Services. The primary measure of 
segment operating performance is Adjusted EBITDA, which is defined as net income (loss) adjusted for income tax expense (benefit), interest expense, 
interest income and other, depreciation and amortization, stock-based compensation expense, restructuring charges, asset impairment charges and other 
special items as determined by management. Adjusted EBITDA includes an allocation of corporate headquarters costs.

The Software reportable segment derives revenue from the sale and lease of software licenses and cloud solutions in the areas of simulation, high-
performance computing, and artificial intelligence to design and optimize high-performance, efficient, innovative and sustainable products and processes 
for improved business performance. The software services and software-related services component of this segment includes consulting, implementation 
services, training, and software-related services focused on product design and development expertise and analysis from the component level up to 
complete product engineering at any stage of the lifecycle. To a much lesser extent, the Software segment includes revenue from the sale of hardware 
products.

The Client Engineering Services reportable segment provides support to the Company’s customers with long-term ongoing expertise. The Company hires 
simulation specialists, industrial designers, design engineers, materials experts, development engineers, manufacturing engineers, data scientists, and 
information technology specialists for placement at customer sites for specific customer-directed assignments.

The “Other” represents innovative services and products, including Toggled, the Company’s LED lighting business. Toggled is focused on developing and 
selling next-generation solid state lighting technology along with communication and control protocols based, in part, on intellectual property for the direct 
replacement of fluorescent tubes with LED lighting. Other businesses combined within Other include potential services and product concepts that are still 
in their development stages.

Inter-segment sales are not significant for any period presented. The CODM does not review asset information by segment when assessing performance, 
therefore no asset information is provided for reportable segments. The accounting policies of the segments are the same as those described in Note 2—

Concentrations of credit risk
The Company’s financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash and trade receivables. The risk 
with respect to trade receivables is partially mitigated by the diversity, both by geography and by industry, of the Company’s customer base. The 
Company’s accounts receivable is derived from sales to a large number of direct customers and resellers around the world. No individual customer 
accounted for 10% or more of revenue in the years ended December 31, 2023, 2022 or 2021.

“Financial Reporng Measure” means a measure that is determined and presented in accordance with the accounng principles used in 
preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measure (including but not 
limited to, “non-GAAP” financial measures, such as those appearing in the Company’s earnings releases or Management Discussion and

incorporaon of the Company where that law was adopted prior to November 28, 2022 and the Company provides an opinion of home 
country counsel to that effect acceptable to the Company’s applicable lisng exchange; (ii) the direct expense paid to a third party to 
assist  in  enforcing  this  Policy  would  exceed  the  Recoverable  Incenve  Compensaon  and  the  Company  has  (A)  made  a  reasonable 
aempt to recover such amounts and (B) provided documentaon

of such aempts to recover to the Company’s applicable lisng exchange; or (iii) recovery would likely cause an otherwise tax-qualified 
rerement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Secon 
401(a)(13) or Secon 411(a) of the Internal Revenue Code of 1986, as amended, and regulaons thereunder.

“Incenve Compensaon” means any compensaon that is granted, earned, or vested based wholly or in part upon the aainment of a 
Financial  Reporng  Measure.  Incenve  Compensaon  does  not  include  any  base  salaries  (except  with  respect  to  any  salary  increases 
earned  wholly  or  in  part  based  on  the  aainment  of  a  Financial  Reporng  Measure  performance  goal);  bonuses  paid  solely  at  the 
discreon of the Compensaon Commiee or Board that are not paid from a “bonus pool” that is determined by sasfying a Financial 
Reporng  Measure  performance  goal;  bonuses  paid  solely  upon  sasfying  one  or  more  subjecve  standards  and/or  compleon  of  a 
specified  employment  period;  non-equity  incenve  plan  awards  earned  solely  upon  sasfying  one  or  more  strategic  measures  or 
operaonal  measures;  and  equity  awards  that  vest  solely  based  on  the  passage  of  me  and/or  aaining  one  or  more  non-Financial 
Reporng Measures. Incenve Compensaon includes any Incenve Compensaon Received on or aer October 2, 2023 pursuant to a 
preexisng contract or arrangement.

“Received:” Incenve Compensaon is deemed “Received” in the Company’s fiscal period during which the Financial Reporng Measure 
specified in the Incenve Compensaon award is aained, even if the payment or grant of the Incenve Compensaon occurs aer the 
end of that period.

“Recoverable Incenve Compensaon” means the amount of any Incenve Compensaon (calculated on a pre-tax basis) Received by a 
Covered Person during the Applicable Period that is in excess of the amount that otherwise would have been Received if the calculaon 
were based on the Restatement. For Incenve Compensaon based on (or derived from) stock price or total shareholder return where 
the  amount  of  Recoverable  Incenve  Compensaon  is  not  subject  to  mathemacal  recalculaon  directly  from  the  informaon  in  the 
applicable Restatement, the amount will be determined by the Compensaon Commiee based on a reasonable esmate of the effect 
of the Restatement on the stock price or total shareholder return upon which the Incenve Compensaon was Received (in which case, 
the Company will maintain documentaon of such determinaon of that reasonable esmate and provide such documentaon to the 
Company’s applicable lisng exchange).

“Restatement” means an accounng restatement of any of the Company’s financial statements filed with the Securies and Exchange 
Commission under the Exchange Act, or the Securies Act of 1933, as amended, due to the Company’s material noncompliance with any 
financial reporng requirement under U.S. securies laws, regardless of whether the Company or Covered Person misconduct was the 
cause  for  such  restatement.  “Restatement”  includes  any  required  accounng  restatement  to  correct  an  error  in  previously  issued 
financial statements that is material to the previously issued financial statements (commonly referred to as “Big R” restatements), or that 
would  result  in  a  material  misstatement  if  the  error  were  corrected  in  the  current  period  or  le  uncorrected  in  the  current  period 
(commonly referred to as “lile r” restatements).
