PART I

Statements contained in this report that are not historical are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including statements regarding our expectations, beliefs, intentions and strategies regarding the future. We intend that such forward-looking statements be subject to the safe-harbor provided by the Private Securities Litigation Reform Act of 1995. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. Words such as “may,” “will,” “should,” “could,” “would,” “predict,” “potential,” “continue,” “expect,” “anticipate,” “future,” “intend,” “plan,” “believe,” “estimate,” and similar expressions, as well as statements in future tense, identify forward-looking statements. However, not all forward-looking statements contain these identifying words.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and potentially inaccurate assumptions. Many events beyond our control may determine whether results we anticipate will be achieved. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected. You should bear this in mind as you consider forward-looking statements. This report lists various important factors that could cause actual results to differ materially from expected and historical results. These factors are intended as cautionary statements for investors within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act. Readers can find them under the heading “Risk Factors” in this Annual Report on Form 10-K, and investors should refer to them. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

Except as required by law, we undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q, 8-K and 10-K reports to the Securities and Exchange Commission ("SEC"). Our filings with the SEC may be accessed at the SEC’s web site at www.sec.gov.

Item 1.    Business

Axon Enterprise, Inc. may be referred to as “the Company,” “Axon,” “we,” or “our.” We were incorporated in Arizona in September 1993 as ICER Corporation. We changed our name to AIR TASER, Inc. in December 1993 and to TASER International, Incorporated in April 1998. In January 2001, we reincorporated in Delaware as TASER International, Inc., and in April 2017, changed our name to Axon Enterprise, Inc.

Our headquarters in Scottsdale, Arizona houses our executive management, sales, marketing, certain engineering, manufacturing, finance and other administrative support functions. Our global software hub is located in Seattle, Washington, and we also have subsidiaries and / or offices located in Australia, Canada, Finland, Germany, Hong Kong, India, Italy, the Netherlands, the United Kingdom, and Vietnam.

Overview

Axon’s mission is to protect life. We fulfill this mission through developing hardware and software products that advance our long-term strategic goals of a) obsoleting the bullet, b) reducing social conflict, c) enabling a fair and effective justice system, and d) building for racial equity, diversity, and inclusion. Our products solve some of society's most challenging problems and our mission attracts top talent.

​

An axon is a nerve fiber that serves as the primary communication link in a nervous system — similarly, we see ourselves as building the nervous system for public safety. Our research & development (“R&D”) investments support continuous innovation on behalf of our customers. Our financial strategy is to build highly recurring, highly profitable businesses.

​

In 2021, we made investments for scale to expand our total addressable market along three axes — introducing new products, selling into new customer market segments, and adding sales channels to new geographic regions. We believe we are serving a $52 billion total addressable market.

Axon’s operations comprise two reportable segments:

Further information about our reportable segments and sales by geographic region is included in Notes 1 and 19 of the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K. For backlog by reportable segment, refer to Part II, Item 7 of this Annual Report on Form 10-K.

Key Product Category Revenue Drivers: What We Offer

Axon products are generally cloud-connected, designed to drive better outcomes and customer experiences, and sold via mutually reinforcing integrated bundles. Our key revenue drivers belong to three broad product categories:

​

Sales and Distribution: Who We Sell To and Where We Deliver

Axon’s direct sales force and strong customer relationships represent key strategic advantages. The majority of our revenues are generated via direct sales, including our online store, although we do leverage distribution partners and third-party resellers.

No customer represented more than 10% of total net sales for the years ended December 31, 2021, 2020 or 2019.

Our primary customer market is U.S. law enforcement. Of the approximately 18,000 law enforcement agencies in the U.S., we have a customer relationship with approximately 17,000. Axon has dedicated sales representatives for the 1,200 largest agencies, which account for approximately 70% of U.S. law enforcement patrol officers. The remaining agencies are served via our telesales team as well as distributors.

In recent years, we have been investing in sales personnel to capture new markets, including the U.S. federal government and military, departments of corrections, the fire and emergency medical services markets, and new geographies outside the U.S. In 2021, we continued to expand our presence in new markets by growing our dedicated sales teams in the Justice and Enterprise markets.

Governmental agencies generally have the ability to terminate our contracts, in whole or in part, for reasons including, but not limited to, non-appropriation of funds.

Resources

Manufacturing and Supply Chain

We perform light manufacturing, final assembly, and final test operations at our headquarters in Scottsdale, Arizona, and own substantially all of the equipment required to develop, prototype, manufacture and assemble our finished products. We have continued to maintain both our ISO 9001 and our ISO 9001:2015 certifications.

We previously took steps to diversify our supply chain and global manufacturing footprint, which positioned us well to manage through the COVID-19 pandemic. Thus far, we have been able to produce and ship our critical core products. However, as we enter 2022 material availability still poses real risks to all businesses that manufacture products. Supplier decommitments remain our largest area of risk and we have seen this practice increase over the course of the pandemic and global supply chain constraints. We proactively manage our supply chain down to third tier suppliers to overcome material shortages as they arise. These actions align to our strategic model to help meet strong product demand while also preparing us to stagger factory work schedules as needed, which enables us to meet compressed build schedules over short periods of time. We continue to adjust strategic inventory levels based on areas of risk (Covid, geopolitical, governmental, etc.) to mitigate potential supply disruptions.  

In light of our broad domestic and international geographic supplier base, we are continuously monitoring our supply chain to manage through potential impacts, identifying alternate shipping / logistic sources, and working with foreign regulators to ensure that our suppliers can provide parts.

We obtain many of our components from single source suppliers; however, because we own the injection molded component tooling used in their production, we believe we could obtain alternative suppliers in most cases without incurring significant production delays. For additional discussion of sources and availability of raw materials, refer to Note 1 to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

We provide limited manufacturer’s warranties on our CEDs and Axon devices, and customers also have the option to purchase extended warranties. For additional information about our warranties, refer to Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

Intellectual Property

We protect our intellectual property with U.S. and international patents and trademarks. Our patents and pending patent applications relate to technology used by us in connection with our products. We also rely on international treaties, organizations and laws to protect our intellectual property. As of December 31, 2021, we hold 253 U.S. patents, 91 U.S. registered trademarks, 155 international patents, and 383 international registered trademarks, and also have numerous patent and trademark applications pending.

We continuously assess whether and where to seek formal protection for particular innovations and technologies based on such factors as the commercial significance of our operations and our competitors’ operations in particular countries and regions, our strategic technology or product directions in different countries, and the degree to which intellectual property laws exist and are meaningfully enforced in different jurisdictions. We have the exclusive rights to many Internet domain names, primarily including “TASER.com”, “Axon.com”, “Axon.net”, “Evidence.com” and “Axon.io.” We also vigorously protect our intellectual property, including trademarks, patents and trade secrets against third-party infringement.

Confidentiality agreements are used with employees, consultants and key suppliers to help ensure the confidentiality of our trade secrets.

Competition

TASER for Law Enforcement, Corrections and Private Security Markets: Our CEDs compete with a variety of other less-lethal alternatives to firearms, including rubber bullets or rubber baton rounds, pepper spray, pepper spray projectiles, mace, traditional stun guns, hand-held remote restraint devices involving a tether, laser dazzlers that cause temporary blindness, stun grenades, long-range acoustic devices, police batons and night sticks. TASER devices offer advanced technology, versatility, portability, effectiveness, built-in accountability systems, and low injury rates, which enable us to compete effectively against other less-lethal alternatives. TASER devices also offer connectivity to our cloud network, which allows agencies to more effectively manage their less-lethal programs and automate use-of-force reporting.

The primary competitive factors in this market include a device’s accuracy, effectiveness, reputation, safety, cost, ease of use, and exceptional customer experience. The design maturity of the TASER platform, as well as our development and sale of a two-shot device, are also key competitive differentiators. We are aware of competitors providing competing CED products primarily in international markets.

TASER for Personal Safety: In the private citizen market, TASER devices compete with firearms and with other less-than-lethal self-defense options such as stun guns and pepper spray-based products including pepper guns and miniature spray cans. The TASER StrikeLight competes in the flashlight category, in which there are dozens, if not hundreds, of competitors, including tactical flashlight providers with and without stun-gun capabilities.

TASER personal safety devices are not stun guns, and have different capabilities, including NMI (neuro-muscular incapacitation) functionality. The broader market for personal safety and home defense is far-reaching, and categories range from threat detection and accountability (dash and doorbell cameras), to home security (home alarms, locks, and response services) to personal defense (firearms, stun guns, TASER devices, pepper spray, tactical flashlights, and personal alarms), to personal tracking and emergency notification mobile applications.

The primary benefit of TASER devices is in less-than-lethal stopping power. Other competitive factors include a device’s cost, effectiveness, safety, ease of use, and available training options.

Sensors — Connected Cameras and Digital Evidence Management Software: The body-worn camera and in-car video/automatic license plate readers market is highly competitive. Our competition includes Motorola Solutions, Utility Associates, Getac, Panasonic Corp., Reveal Media, Coban Technologies, L3 Mobile-Vision, Digital Ally, Visual Labs, Intrensic, LLC, as well as Safety Vision, Rekor, and Genetec.

The market for software solutions to improve public safety agency workflows is both highly fragmented and highly competitive. Our cloud-based digital evidence management system, Axon Evidence, competes with both cloud-based platforms and on-premises based systems designed by third-parties or developed internally by an agency's technology staff. Our competition includes Motorola Solutions, Panasonic Corp., IBM, Oracle, FotoWare, Vidizmo, NICE, QueTel, OpenText, and FileOnQ among others.

Key competitive factors in this market include product performance, product features (including live-streaming, GPS tracking, and pre-event buffering), battery life, product quality and warranty, total cost of ownership, data security, data and information workflows, company reputation and financial strength, and relationships with customers.

Productivity and Real-Time Operations — Records Management System (RMS) and Computer Aided Dispatch (CAD): The RMS and CAD markets are highly competitive and highly fragmented. We have identified more than 50 software providers, including Motorola Solutions, Tyler Technologies, Central Square Technologies (formerly Superion, TriTech and Aptean), Northrop Grumman, Hexagon AB, Niche Technology Inc., Caliber Public Safety (parent, Harris Systems USA), Saab, SOMA Global, RapidDeploy, Sopra Steria, and Mark 43 Inc. In addition, not all law enforcement agencies use software for report writing — some still use paper. We believe our network of camera sensors and digital evidence management platform give us a strategic advantage in these product categories. Our Respond offering competes both with real-time operations platforms that ingest body camera video feeds, like Motorola’s CommandCentral Aware, Hitachi's Visualization Suite and Genetec's Citigraf as well as platforms that ingest video feeds exclusively from surveillance cameras, like Rave Mobile Safety, LiveEarth and Mutualink among others.

Seasonality

We have historically experienced higher net sales in our fourth quarter compared to other quarters in our fiscal year due primarily to municipal budget cycles. Additionally, new product introductions can significantly impact the cadence of net sales, product costs and operating expenses. Municipal law enforcement budgets tend to feature a mix of fiscal years that end in either June, September or December. However, historical seasonal patterns, municipal

budgets or historical patterns of product introductions should not be considered reliable indicators of our future net sales or financial performance.

Governmental Regulation  

We are subject to a variety of laws and regulations in the United States and abroad that involve matters central to our business, including, for example, laws and regulations related to: privacy and data protection, security, retention, and deletion; rights of publicity; content; intellectual property; regulation of our CEDs as firearms; advertising; marketing; distribution; electronic contracts and other communications; competition; consumer protection; telecommunications; product liability; taxation; labor and employment; economic or other trade prohibitions or sanctions; securities; and online payment services. There are a number of legislative proposals in the U.S., at both the federal and state level, that could impose new obligations in areas affecting our business, such as liability for copyright infringement by third parties. Foreign laws and regulations can impose different obligations or be more restrictive than those in the U.S.

These U.S. federal and state and foreign laws and regulations, which in some cases can be enforced by private parties in addition to government entities, are constantly evolving and can be subject to significant change. As a result, the application, interpretation, and enforcement of these laws and regulations are often uncertain and may be interpreted and applied inconsistently from country to country and inconsistently with our current policies and practices.

TASER and Axon Devices

For our TASER products, we rely on the opinions of the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, including the determination that a device that does not expel projectiles by the action of an explosive is not classified as a firearm.

Federal regulation of sales in the U.S.: Our currently offered CEDs are not firearms regulated by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, but our consumer products are regulated by the U.S. Consumer Product Safety Commission. There are currently no federal laws restricting sales of our core currently offered CED products in the U.S.

Axon devices using lithium batteries are subject to U.S.-DOT/UN 38.3 for transportation.

Our CED products are also subject to testing, safety and other standard organizations such as the American National Standards Institute, the International Electrotechnical Commission, the National Institute of Standards and Technology, and Underwriters Laboratories. These regulations also affect CEDs with Axon Signal technology, including Signal Performance Power Magazine technology, and TASER 7 battery packs.

Federal regulation of international sales: Our CEDs are considered a “crime control” product by the U.S. Department of Commerce (“DOC”) for export directly from the U.S. Consequently, we must obtain an export license from the DOC for the export of our CED devices from the U.S. to any country other than Canada.

Federal regulation of foreign national employees: Our CED technology is considered controlled “technology” by the U.S. DOC and is categorized as a “deemed export” for any foreign national employees exposed to the technology within the U.S. Consequently, we must obtain an export licenses from the DOC for any deemed export within the U.S. made to a foreign national employee exposed to the deemed controlled technology. Deemed export licenses are subject to DOC approvals and issued licenses require annual status reports for the stated employees.

State and local regulation: Our CEDs are controlled, restricted or, less frequently, prohibited by a number of state and local governments. As of December 31, 2021, the general public in Hawaii and Rhode Island is prohibited from possessing certain of our TASER-branded devices. Some cities and municipalities also prohibit private citizen possession or use of our CED products. Subsequent to December 31, 2021, Hawaii lifted restrictions on possession related to TASER-branded devices.

International regulation of foreign imports and sales: Certain jurisdictions prohibit, restrict, or require a permit for the importation, sale, possession or use of CEDs, including in some countries by law enforcement agencies, limiting our international sales opportunities.

U.S. and International regulation of component movements globally: We rely on a global supply chain of components across our product lines with most final assembly occurring in the U.S. Export of these components from abroad is subject to shifting regulatory landscapes imposed by both the foreign government and U.S. authorities upon import.

International regulation of foreign-based operations: We maintain foreign operations in several countries globally for purposes of logistics, sales, and R&D support. Depending on these activities, regulations can include business activity licensing and registration, import permits and recordkeeping, warehousing & storage security and permitting, and government reporting.

Radio Spectrum Devices

Certain of our products utilize the radio spectrum to provide wireless voice, data and video communications services. The allocation of spectrum is regulated in the U.S. and other countries and limited spectrum space is allocated to wireless services and specifically to public safety users. In the U.S., the Federal Communications Commission (“FCC”) regulates spectrum use by non-federal entities and federal entities. Similarly, countries around the world have one or more regulatory bodies that define and implement the rules for use of radio spectrum and electromagnetic interference, pursuant to their respective national laws. We manufacture and, after receiving the required approvals, we market our products in spectrum bands already made available by regulatory bodies.

Axon body worn cameras, docks, fleet vehicle cameras and signal devices are subject to FCC’s rules and regulations. The FCC regulates not only the "intentional radiation" of radio transmitters, but also the "unintentional radiation" of noise from all sorts of electrical equipment. Current Axon products use Bluetooth, WiFi and/or Long Term Evolution (“LTE”) radio technologies. With the integration of LTE technologies, we must also apply for the approval of private certifications such as Cellular Telecommunications and Internet Association certification, required by FirstNet and other operators. These regulations affect CEDs with Signal technology, including the TASER 7, SPPM, and future CEDs implementing wireless technology.

Environmental Regulations

We are subject to various state, federal and international laws and regulations governing the environment, including restricting the presence of certain substances in our products and making producers of those products financially responsible for the collection, treatment, recycling and disposal of such products.

The European Union (“EU”) has published Directives on the restriction of certain hazardous substances in electronic and electrical equipment (the “RoHS Directive”) and on electronic and electrical waste management (the “WEEE Directive”). The RoHS Directive restricts the use of a number of substances, including lead. The WEEE Directive directs members of the EU to enact laws, regulations, and administrative provisions to ensure that producers of electric and electronic equipment are financially responsible for the collection, recycling, treatment and environmentally responsible disposal of certain products sold into the EU. In addition, similar environmental legislation has been enacted in other jurisdictions, including the U.S. (under federal and state laws) and other countries.

In addition, the EU has defined a regulation for the registration, evaluation, authorization and restriction of chemicals that places responsibility on companies to manage the risks from chemicals contained in products and to provide safety information about such substances. Manufacturers and importers are required to gather information on the properties of the chemical substances in their products and provide for their safe handling. As of January 5, 2021, companies supplying products on the EU market containing substances of very high concern as identified by the EU have to submit information on these products to the European Chemicals Agency. The information in their database is then made available to waste operators and consumers.

Other countries have adopted chemical restrictions regulations, including the U.S., Canada, and Australia.

Privacy Regulations

We are subject to laws and regulations that dictate whether, how, and under what circumstances we can collect, transfer, process and/or receive certain data that is critical to our operations, including data shared between countries or regions in which we operate and data shared among our products and services. We continue to monitor and assess for compliance as the regulatory environment evolves both within the United States and in relevant international markets.

The European General Data Protection Regulation ("GDPR") took effect in May 2018 and applies to many of our products and services that provide service in Europe. The GDPR includes operational requirements for companies that receive or process personal data of residents of the EU. The GDPR includes significant penalties for non-compliance. In addition, some countries have passed legislation implementing data protection requirements or requiring local storage and processing of data or similar requirements.

Human Capital Resources

Our success depends on the continued service of our employees and on our ability to continue to attract, retain, and motivate top talent. To facilitate this, we strive to create a diverse and inclusive environment at Axon, with equitable opportunities for employee growth and development, supported by strong compensation and benefits and by programs that build connections between our employees and their communities. Axon’s mission is central to our recruiting and retention efforts.

As of December 31, 2021, we had 2,148 full-time employees and 844 temporary employees (temporary employees include contractors, interns, and consultants). The breakdown of our full-time employees by department was as follows: 215 direct manufacturing employees, 614 research and development employees, 381 administrative and support employees, 452 sales employees, and 486 employees within product support. Our employees are not covered by any collective bargaining agreement, and we have never experienced a work stoppage. We believe that our relations with our employees are strong.

During fiscal 2021, the number of full-time employees increased by 438, primarily for sales and research and development resources. We closed the year with our regrettable attrition rate^(b) at 1.3%, under the annual goal of 2.5%. More than 90% of employees reported feeling proud to work at Axon during this year’s employee engagement survey.

Diversity and Inclusion

We embrace diversity, equity and inclusion. A truly innovative workforce needs to be diverse, leverage the skills and perspectives of a wealth of backgrounds and experiences, and ensure that all employees are equitably empowered to succeed. We continue to focus on the hiring, retention, development, and advancement of women and underrepresented communities. We are focused on recruiting diverse candidates and on internal talent development of our diverse leaders so that they can advance their careers and move into leadership positions.

Our employee affinity groups are company-sponsored, employee-led communities that address specific needs, priorities, and barriers to success for each community of focus. These groups provide a forum for employees to discuss problems and craft solutions for each community of focus, while also creating leadership and professional development opportunities for members. As of December 31, 2021, we had six affinity groups — Axon Allies for LGBTQ+ employees, APIA for Asian Pacific Islander employees, HOLA for Hispanic employees, Axon Mosaic for Black employees, Axon Vets for service veterans, and Women at Axon. Each affinity group is inclusive of employees who identify as members of each community, as well as allies.

In 2021, we broadened our already strong support for our customers and the communities they are sworn to protect. We added a Vice President of Community Impact to build and lead a team dedicated to listening to

communities, seeking citizen feedback, and keeping them safe and informed on a variety of topics. In 2020, we launched a company-wide R&D initiative that allowed employees to break from their regular responsibilities and solely focus on developing life-changing solutions to better protect citizens and law enforcement. Internally, we continue to listen to our employees with town hall sessions, provide expert-led webinars for parents, and host community round tables.

Health and Safety

The health and safety of our employees is of utmost important to us. We conduct regular self-assessments and audits to ensure compliance with our health and safety guidelines and regulatory requirements. Our ultimate goal is to achieve a level of work-related injuries as close to zero as possible through continuous investment in our safety programs. We provide protective gear (e.g. eye protection, masks and gloves) as required by applicable standards and as appropriate given employee job duties. Additionally, during the COVID-19 pandemic, we have invested heavily to help ensure the health of our employees. Through the use of education and awareness, provision of necessary personal protective equipment, and changes to our manufacturing facilities and screening, we strive to make our workplaces a safe place for employees during the workday.

To promote mental and emotional wellbeing, all full time employees globally were provided free, unlimited access by Axon to Ginger. Ginger is a 24/7 resource that includes individualized coaching via text in addition to access to articles and activities offering guidance on maintaining emotional balance throughout tumultuous times.

Additionally, we have a Wellness Incentive Program for our domestic employees that incentivizes healthy lifestyles. The program rewards employees for completing a variety of well-being activities that help foster their financial wellness, mental health, social wellbeing, community engagement and nutrition.

Item 1A.    Risk Factors

Because of the following factors, as well as other variables affecting our operating results, our past financial performance may not be a reliable indicator of our future performance and historical trends should not be used to anticipate our results or trends in future periods. You should carefully consider the trends, risks and uncertainties described below and other information in this Form 10-K and subsequent reports filed with or furnished to the SEC before making any investment decision with respect to our securities. If any of the following trends, risks or uncertainties actually occurs or continues, our business, financial condition or operating results could be materially adversely affected, the trading prices of our securities could decline, and you could lose all or part of your investment. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by this cautionary statement.

Strategic Risks

We are materially dependent on acceptance of our products by law enforcement markets, throughout the world. If law enforcement agencies do not continue to purchase and use our products, our revenues will be adversely affected.

At any point, due to external factors and opinions, whether or not related to product performance, law enforcement agencies may elect to no longer purchase our CEDs or other products.

We substantially depend on sales of our TASER CEDs, and if these products do not continue to be widely accepted, our growth prospects will be diminished.

In the years ended December 31, 2021, 2020 and 2019, we derived a significant portion of our revenues from sales of TASER brand devices and related cartridges, and expect to depend on sales of these products for a significant portion of our revenue for the foreseeable future. A decrease in the selling prices of, or demand for these products, or their failure to maintain broad market acceptance, would significantly harm our growth prospects, operating results and financial condition.

If we are unable to design, introduce, sell and deploy new products or new product features successfully, our business and financial results could be adversely affected.

Our future success will depend on our ability to develop new products or new product features that achieve market acceptance in a timely and cost-effective manner. These products include, but are not limited to, Axon Records, Axon Respond, and future generations of the TASER CED and Axon Body Cameras. The development of new products and new product features is complex, time consuming and expensive, and we may experience delays in completing the development and introduction of new products. We may choose to carry higher level of inventories to mitigate the risk of production delays, which may in turn expose us to an increased risk of obsolescence.

We are devoting significant resources to develop and deploy our cloud-based productivity and real-time operations SaaS solutions, which we intend to broadly deploy to a large number of customers. Customer requirements for these products are complex and varied. If we are unable to develop scalable solutions that can be consistently configured for customers with minimal effort, or if we are unable to grow a professional services team that can consistently configure our products to meet the requirements of large numbers of customers  in a timely and cost-effective manner, our ability to broadly scale our cloud-based productivity and real-time operations SaaS solutions could be negatively impacted, and our deployment costs could negatively impact our operating results.

We cannot provide any assurance that products that we may develop in the future will achieve market acceptance. If we fail to develop new products or new product features on a timely basis that achieve market acceptance, our business, financial results and competitive position could be adversely affected.

We face risks associated with rapid technological change and new competing products.

The technology associated with law enforcement devices and software is receiving significant attention and is rapidly evolving. While we have some patent protection in certain key areas of our CED, Axon device and SaaS technology, new technology may result in competing products that operate outside our patents and could present significant competition for our products, which could adversely affect our business, financial results and competitive position.

Our future success is dependent on our ability to expand sales through direct sales and distributors and our inability to increase direct sales or recruit new distributors would negatively affect our sales.

Our distribution strategy is to pursue sales through multiple channels with an emphasis on direct sales and independent distributors. We are focusing on direct sales to larger agencies through our regional sales managers and our inability to grow sales to these agencies in this manner could adversely affect our sales. Our inability to establish relationships with and retain law enforcement equipment distributors, who we believe can successfully sell our products, would adversely affect our sales. If we do not competitively price our products, meet the requirements of

our distributors or end-users, provide adequate marketing support, or comply with the terms of our distribution arrangements, our distributors may fail to aggressively market our products or may terminate their relationships with us. These developments would likely have a material adverse effect on our sales. Our reliance on the sales of our products by others also makes it more difficult to predict our revenues, cash flow and operating results.

In certain states and foreign jurisdictions we have decided to pursue sales directly with law enforcement customers, rather than working through established distribution channels. Our customers may have strong working relationships with distributors and we may face resistance to this change. If we do not overcome this resistance and effectively build a direct relationship with our customers, sales may be adversely affected.

Acquisitions, joint ventures, and other strategic investments may have an adverse effect on our business.

We may consider additional acquisitions, joint ventures, or other strategic investments as part of our long-term business strategy. These transactions involve significant challenges and risks including that the transaction does not advance our business strategy, expected synergies are not achieved, we do not realize a satisfactory return on our investment, we experience difficulty in the integration or coordination of new employees, business systems, and technology, we incur unanticipated liabilities or impairments, or management’s attention is diverted from our other businesses. These events could harm our operating results, financial condition or cash flows.

We are highly dependent on the services of Patrick W. Smith, our Chief Executive Officer.

Our future success depends upon our ability to retain executive officers, specifically Patrick W. Smith, and any failure to do so could adversely impact our business, prospects, new product development, financial condition and operating results.

Operational Risks

Catastrophic events may disrupt our business.

A disruption or failure of our systems or operations in the event of a major earthquake, weather event, fire, explosion, failure to contain hazardous materials, industrial accident, utility failure, cyber-attack, terrorist attack, public health crisis, or other catastrophic event could cause delays in completing sales, providing services, or performing other mission-critical functions. A catastrophic event that results in the destruction or disruption of any of our critical business or information technology systems could harm our ability to conduct normal business operations and our operating results as well as expose us to claims, litigation and governmental investigations and fines.

The COVID-19 global pandemic has adversely affected workforces, economies, and financial markets globally, and led to an economic downturn. As an essential provider of products and services for law enforcement and other first responders, we remain focused on protecting the health and well-being of our employees while assuring the continuity of our business operations.

Although the severity of the pandemic has lessened with the rollout of vaccines and travel restrictions, remote working and schooling and social distancing requirements have been lifted or eased in varying degrees in varying locations throughout the United States and the world, continuing surges and variants have caused certain restrictions to be re-implemented in varying degrees and in varying locations. The severity and duration of the pandemic, including future surges and variants, is impossible to predict. As a result, the ongoing pandemic continues to present various risks that may affect our operations and financial results, including, but not limited to:

These events have had and could continue to have an impact on our operations. If our backup and mitigation plans are not sufficient to minimize business disruption, our financial results could be adversely affected. We are continuously monitoring our operations and intend to take appropriate actions to mitigate the risks arising from the COVID-19 pandemic, but there can be no assurances that we will be successful in doing so.

Higher costs or unavailability of materials could adversely affect our financial results.

We depend on certain domestic and international suppliers for the delivery of components used in the assembly of our products. Our reliance on third-party suppliers creates risks related to our potential inability to obtain an adequate supply of components or sub-assemblies and reduced control over pricing and timing of delivery of components and sub-assemblies. Specifically, we depend on suppliers of sub-assemblies, machined parts, injection molded plastic parts, printed circuit boards, custom wire fabrications and other miscellaneous customer parts for our products. Although we have and are implementing additional long-term agreements with strategic suppliers to mitigate the risk of supply continuity, there remains risk across our supply chain while we extend our supplier contract program, and there is no guarantee that supply will not be interrupted.

Single or sole-source components used in the manufacture of our products may become unavailable or discontinued. Delays caused by industry allocations or obsolescence may take weeks or months to resolve. In some cases, parts obsolescence may require a product re-design to ensure quality replacement components. These delays could cause significant delays in manufacturing and loss of sales, leading to adverse effects significantly impacting our financial condition or results of operations and could injure our reputation.

A significant number of our raw materials or components are comprised of petroleum-based products or incur some form of landed cost associated with transporting the raw materials or components to our facility. Our freight and import costs and the timely delivery of our products could be adversely impacted by a number of factors which could reduce the profitability of our operations, including: higher fuel costs; potential port closures; customs clearance issues; increased government regulation or regulatory changes for imports of foreign products into the U.S.; delays created by terrorist attacks or threats, public health issues, national disasters or work stoppages; and other matters. Any interruption of supply for any material components of our products could significantly delay the shipment of our products and have a material adverse effect on our revenues, profitability and financial condition. For example, other industries are experiencing a significant shortage of semiconductors in their supply chains. We are tracking second-and third-level constraints and have taken steps to mitigate the potential impacts by building in buffers in our raw materials inventory and ensuring our suppliers have adequate access to raw material levels aligned to our forecasts. Disruptions in the semi-conductor supply chain could cause a disruption in our ability to make our products.

International or domestic geopolitical or other events, including the imposition of new or increased tariffs and/or quotas by the U.S. government on any of these raw materials or components and other government trade policies, could adversely impact the supply and cost of these raw materials or components, and could adversely impact the profitability of our operations. In particular, the implementation of tariffs and trade restrictions as well as changes in trade policies between the U.S. and China may have an adverse effect on our supply chain from a sourcing and cost perspective. We source certain raw materials from China, as do some of our suppliers. While we have actively implemented programs to increase buffer inventory levels as well as transition from China along with secondary sources of raw materials outside of China, future actions or events could result in a material adverse effect on our revenues, profitability and financial condition.

To the extent demand for our products increases, our future success will be dependent upon our ability to manage our growth and to increase manufacturing production capacity, which may be accomplished by the implementation of customized manufacturing automation equipment.

To the extent demand for our products increases significantly in future periods, one of our key challenges will be to increase our production capacity to meet sales demand while maintaining product quality. Our primary strategies to accomplish this include introducing additional shifts, increasing the physical size of our assembly facilities, the hiring of additional production staff, and the implementation of additional customized automation equipment. The investments we make in this equipment may not yield the anticipated labor and material efficiencies. Our inability to meet any future increase in sales demand or effectively manage our expansion could have a material adverse effect on our revenues, financial results and financial condition.

Delays in product development schedules may adversely affect our revenues and cash flows.

The development of CEDs, devices, sensors and software is a complex and time-consuming process. New products and enhancements to existing products can require long development and testing periods. Our focus on our SaaS platform also presents complex development issues. Significant delays in new product or service releases or significant problems in creating new products or services could adversely affect our business, financial results and competitive position.

We expend significant resources in anticipation of a sale due to our lengthy sales cycle and may receive no revenue in return.

Generally, law enforcement and corrections agencies consider a wide range of issues before committing to purchase our products, including product benefits, training costs, the cost to use our products in addition to, or in place of, other products, budget constraints and product reliability, safety and efficacy. The length of our sales cycle may range from a few weeks to as long as several years. Adverse publicity surrounding our products or the safety of such products has in the past, and could in the future, lengthen our sales cycle with customers. In the past, we believe that our sales were adversely impacted by negative publicity surrounding our products or the use of our products. We may incur substantial selling costs and expend significant effort in connection with the evaluation of our products by potential customers before they place an order. If these potential customers do not purchase our products, we will have expended significant resources and received no revenue in return.

Changes in civil forfeiture laws may affect our customers’ ability to purchase our products.

Some of our customers use funds seized through civil forfeiture proceedings to fund the purchase of our products. Legislative changes could impact our customers’ ability to seize funds or use seized funds to fund purchases. Changes in civil forfeiture statutes or regulations are outside of our control and could limit the amount of funds available to our customers, which could adversely affect the sale of our products.

If our security measures or those of our third-party cloud storage providers are breached and unauthorized access is obtained to customers’ data or our data, our network, data centers and service may be perceived as not being secure, customers may curtail or stop using our service and we may incur significant legal and financial exposure and liabilities.

Our service involves the storage and transmission of customers’ proprietary information, and security breaches could expose us to a risk of loss of information or the total or partial deletion or encryption of all stored customer data, litigation and possible liability. We devote significant resources to engineer secure products and ensure security vulnerabilities are mitigated, and we require our third-party service providers to do so as well. Despite these efforts, security measures may be breached as a result of third-party action, employee error, and malfeasance or otherwise. Breaches could occur during transfer of data to data centers or at any time, and result in unauthorized access to our data or our customers’ data. Third parties may attempt to fraudulently induce employees or customers into disclosing sensitive information such as usernames, passwords or other information in order to gain access to our data or our customers’ data. Additionally, hackers may develop and deploy viruses, worms, and other malicious software programs that attack or gain access to our networks and data centers.

Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently, grow more complex over time, and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Moreover, our security measures and those of our third-party service providers or customers may not detect such security breaches if they occur. Although we have developed systems and processes that are designed to protect our data and user data, to prevent data loss, and to prevent or detect security breaches, we cannot assure that such measures will provide absolute security, and we may incur significant costs in protecting against or remediating cyber-attacks.

A security breach could expose us to a risk of loss or inappropriate use of proprietary and sensitive data, or the denial of access to this data. A real or perceived security breach could also result in a loss of confidence in the security of our service, disrupt our business, damage our reputation, lead to legal liability, negatively impact our future sales and significantly harm our growth prospects, operating results and financial condition.

Defects or disruptions in our services could impact demand for our services and subject us to substantial liability.

We currently serve our Axon Evidence customers from third-party cloud storage providers based in the U.S. and other countries. Interruptions in our service, or loss or corruption of digital evidence, may reduce our revenue, cause us to issue credits or pay penalties, cause customers to file litigation against us, cause customers to terminate their subscriptions and adversely affect our renewal rates and our ability to attract new customers. Our business will also be harmed if our customers and potential customers believe our service is unreliable.

Since our customers use our services for important aspects of their operations, any errors, defects, disruptions in service or other performance problems could hurt our reputation and may damage our customers’ operations. As a result, customers could elect to not renew our services or delay or withhold payment to us. We could also lose future sales or customers may make warranty or other claims against us, which could result in an increase in our warranty expense, an increase in collection cycles for and decline in the collectability of accounts receivable, and an increase in the expense and risk of litigation.

Defects in our products could reduce demand for our products and result in a loss of sales, delay in market acceptance and damage to our reputation.

Complex components and assemblies used in our products may contain undetected defects that are subsequently discovered at any point in the life of the product. Defects in our products could result in a loss of sales, delay in market acceptance, damage to our reputation and increased warranty costs, which could adversely affect our business, financial results and competitive position.

Our international operations expose us to additional risks that could harm our business, operating results, and financial condition.

Our international operations are significant, and we plan to continue to grow internationally by acquiring existing entities or setting up new legal entities in new markets. In certain international markets, we have limited operating experience and may not benefit from any first-to-market advantages or otherwise succeed. In addition to risks described elsewhere in this section, our international operations expose us to other risks, including the following:

Additionally, changes in international local political, economic, regulatory, tax, social, and labor conditions may adversely harm our business and compliance with complex foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business. These numerous and sometimes conflicting laws and regulations include, among others, environmental regulations, internal control and disclosure rules, privacy and data protection requirements, anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act, and other local laws prohibiting corrupt payments to governmental officials, and competition regulations, among others.

Our business in the United Kingdom may be negatively impacted by the exit of the United Kingdom from the EU (commonly referred to as "Brexit"). The exit itself could negatively impact the United Kingdom and other economies, which could adversely affect sales of our products and services. We may also experience increased volatility in the value of the pound sterling, the euro and other European currencies. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations in the United Kingdom and the EU, and we may incur additional costs or need to make operational changes as we adapt to potentially divergent regulatory frameworks.

Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our brand, our international growth efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies and procedures designed to ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors, or agents will not violate our policies.

We depend on our ability to attract and retain our key management, sales and technical personnel.

Our success depends upon the continued service of our key management personnel. Our success also depends on our ability to continue to attract, retain and motivate qualified technical employees. Although we have employment agreements with our officers and other members of our executive management team, the employment of such persons is “at-will” and either we or the employee can terminate the employment relationship at any time, subject to the applicable terms of the employment agreements.

We have unique equity incentives designed to attract and retain long-term employees. We utilize these plans to align pay and performance and drive shareholder returns while reducing near-term cash expenditures. Our equity incentives and ongoing stock and option grants are subject to having sufficient shares approved by our shareholders. If we are unable to obtain shareholder approval, we may be unable to attract and retain top talent. The competition for our key employees is intense and market competition for top talent has increased since our introduction of our innovative performance-based stock compensation plans in 2018. The loss of the service of one or more of our key personnel could adversely impact our business, prospects, financial condition and operating results.

Global economic conditions could materially adversely affect our revenue and results of operations.

Our inability to offset price inflation in our materials, components, shipping, or labor through increased prices to customers with long-term fixed contracts and formula-based or long-term fixed price contracts with suppliers could adversely affect our business, financial condition and results of operations.

Our suppliers may fail to deliver components according to schedules, prices, quality and volumes that are acceptable to us, or we may be unable to manage these components effectively.

Our products contain many parts purchased globally from numerous suppliers, including single-source direct suppliers, which exposes us to multiple potential sources of component shortages.  Unexpected changes in business

conditions, materials pricing, labor issues, wars, trade policies, natural disasters, health epidemics such as the global COVID-19 pandemic, trade and shipping disruptions, port congestions and other factors beyond our or our suppliers’ control could also affect these suppliers’ ability to deliver components to us or to remain solvent and operational.  We have used alternative parts to mitigate the challenges caused by these shortages, but there is no guarantee we may be able to continually do so as we scale production to meet projected future sales activity.  Additionally, if our suppliers do not accurately forecast and effectively allocate production or if they are not willing to allocate sufficient production to us, or they decommit to us previously agreed to supply levels, it may reduce our access to components and require us to search for new suppliers.  The unavailability of any component or supplier could result in production delays, as well as impact our ability to fulfill our obligations under customer contracts.  While we believe that we will be able to secure additional or alternate sources for most of our components, there is no assurance that we will be able to do so quickly or at all.  As the scale of our hardware production increases, we will also need to accurately forecast, purchase, warehouse and transport components at high volumes to our manufacturing facilities. If we are unable to accurately match the timing and quantities of component purchases to our actual needs, we may incur unexpected production disruption, storage, transportation and write-off costs, which may harm our business and operating results.

Financial Risks

An increasing percentage of our revenue is derived from subscription billing arrangements which may result in delayed cash collections and may increase customer credit risk on receivables and contract assets.

A growing portion of our sales are derived from subscription billing arrangements and on an open credit basis. While we record an estimate of expected credit losses and perform ongoing reviews of trade accounts receivables, if we become aware of information related to the creditworthiness of a major customer, or if future actual default rates on receivables in general differ from those currently anticipated, we may have to adjust our expected credit loss reserve, which could adversely affect our business, financial condition or operating results.

We may experience a decline in gross margins due to a shift in product sales from CEDs to software and sensors products and services which may continue to carry a lower gross margin.

We continue to invest in the growth of the Software and Sensors segment, and this expected growth may result in a higher percentage of total revenues being comprised of Software and Sensors products and services. Gross margin as a percentage of net sales for the Software and Sensors segment is currently lower than that of the TASER segment, and may continue to be lower in the future.

SaaS revenue for Axon Evidence is recognized over the terms of the contracts, which may be several years, and, as such, trends in new business may not be immediately reflected in our operating results.

Our SaaS service revenue is generally recognized ratably over the terms of the contracts, which generally range from one to five years. As a result, most of the SaaS revenue we report each quarter is the result of agreements entered into during previous quarters. Consequently, current positive or negative trends in this portion of our business may not be fully reflected in our revenue results for several periods.

Most of our end-user customers are subject to budgetary and political constraints that may delay or prevent sales.

Most of our end-user customers are government agencies. These agencies often do not set their own budgets and therefore, have limited control over the amount of money they can spend. In addition, these agencies experience political pressure that may dictate the manner in which they spend money. As a result, even if an agency wants to acquire our products, it may be unable to purchase them due to budgetary or political constraints, particularly in challenging economic environments. There can be no assurance that the economic, budgeting or political issues will not worsen and adversely impact sales of our products. Some government agency orders may also be canceled or substantially delayed due to budgetary, political or other scheduling delays, which frequently occur in connection with the acquisition of products by such agencies, and such cancellations may accelerate or be more severe than we have experienced historically.

Due to municipal government funding rules, certain of our contracts are subject to appropriation, termination for convenience, or similar cancellation clauses, which could allow our customers to cancel or not exercise options to renew contracts in the future.

Although we have entered into contracts for the delivery of products and services in the future and anticipate the contracts will be completed, if agencies do not appropriate money in future year budgets, terminate contracts for convenience or if other cancellation clauses are invoked, revenue and cash associated with these bookings will not ultimately be recognized, and could result in a reduction to bookings and revenue.

We maintain most of our cash balances, some of which are not insured, at four depository institutions.

We maintain the majority of our cash and cash equivalents accounts at three depository institutions. As of December 31, 2021, the aggregate balances in such accounts at these three institutions were $347.3 million. Our balances with these institutions regularly exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits for domestic deposits and various foreign deposit insurance programs covering our deposits in Australia, Canada, Finland, Germany, Hong Kong, India, Italy, the Netherlands, Spain, the United Kingdom, and Vietnam.

We could suffer losses with respect to the uninsured balances if the depository institutions failed and the institution’s assets were insufficient to cover its deposits and/or the governments did not take actions to support deposits in excess of existing insurance limits. Any such losses could have a material adverse effect on our liquidity, financial condition and results of operations.

Stock compensation expense may have a material, unpredictable impact on our results of operations.

We have historically granted and expect to continue to grant stock-based compensation to key employees and non-employee directors as a means of attracting and retaining highly qualified personnel. All stock-based awards are required to be recognized in our financial statements based on their grant date fair values. The amount recognized for stock compensation expense could vary depending on a number of assumptions or changes that may occur.

For awards containing multiple service, performance and market conditions, where all conditions must be satisfied prior to vesting, compensation expense is recognized over the requisite service period, which is defined as the longest explicit, implicit or derived service period, based on management’s estimate of the probability and timing of the performance criteria being satisfied, adjusted at each balance sheet date. Changes in the subjective and probability-based assumptions can materially affect the estimates of the fair value of the awards and timing of recognition of stock-based compensation expense and consequently, the related amount recognized in our statements of operations and comprehensive income.

If we achieve specific operational goals and the covered employees complete the requisite service conditions for  the performance-based awards with multiple service, performance, and market conditions, including our CEO Performance Award and our eXponential Stock Performance Plan ("XSPP"), we will recognize stock compensation expense regardless of whether the market conditions are achieved and the underlying tranches vest.

Our financial performance is subject to risks associated with changes in the value of the U.S. dollar versus local currencies.

For current and potential international customers whose contracts are denominated in U.S. dollars, the relative change in local currency values creates relative fluctuations in our product pricing. These changes in international end-user costs may result in lost orders and reduce the competitiveness of our products in certain foreign markets. Additionally, intercompany sales to our non-U.S. dollar functional currency international subsidiaries are transacted in U.S. dollars which could increase our foreign exchange rate risk caused by foreign currency transaction gains and losses.

For non-U.S. dollar denominated sales, weakening of foreign currencies relative to the U.S. dollar generally leads us to raise international pricing, potentially reducing demand for our products. Should we decide not to raise local prices to fully offset the dollar’s strengthening, the U.S. dollar value of our foreign currency denominated sales and earnings would be adversely affected. We do not currently engage in hedging activities. Fluctuations in foreign

currency could result in a change in the U.S. dollar value of our foreign denominated assets and liabilities including accounts receivable. Therefore, the U.S. dollar equivalent collected on a given sale could be less than the amount invoiced causing the sale to be less profitable than contemplated.

We also import selected components which are used in the manufacturing of some of our products. Although our purchase orders are generally in U.S. dollars, weakness in the U.S. dollar could lead to price increases for the components.

Unanticipated changes in our effective tax rate and additional tax liabilities may impact our operating results.

We are subject to income taxes in the U.S. and various jurisdictions outside of the U.S. Our effective tax rate could fluctuate due to changes in the mix of earnings and losses in countries with differing statutory tax rates. Our tax expense could also be impacted by changes in non-deductible expenses, changes in excess tax benefits related to exercises of stock options and vesting of restricted stock units, changes in the valuation of deferred tax assets and liabilities and our ability to utilize them, the applicability of withholding taxes, and changes in our liability for unrecognized tax benefits.

We are subject to tax examinations in multiple jurisdictions. While we regularly evaluate new information that may change our judgment resulting in recognition, derecognition or change in measurement of a tax position taken, there can be no assurance that the final determination of any examinations will not have an adverse effect on our operating results and financial position.

Our tax provision could also be impacted by changes in federal, state or international tax laws including fundamental tax law changes applicable to corporate multinationals.

Additionally, we may be subject to additional tax liabilities due to changes in non-income-based taxes resulting from changes in federal, state, city or international tax laws, changes in taxing jurisdictions’ administrative interpretations, decisions, policies, and positions, results of tax examinations, settlements or judicial decisions, changes in accounting principles, changes to the business operations, including acquisitions, as well as the evaluation of new information that results in a change to a tax position taken in a prior period.

Our revenues and operating results may fluctuate unexpectedly from quarter-to-quarter, which may cause our stock price to decline.

Our revenues and operating results have varied significantly in the past and may vary significantly in the future due to various factors, including, but not limited to:

As a result of these and other factors, we believe that period-to-period comparisons of our operating results may not be meaningful in the short term, and our performance in a particular period may not be indicative of our performance in any future period.

Legal and Compliance Risks

We may face personal injury, wrongful death and other liability claims that harm our reputation and adversely affect our sales and financial condition.

Our CED products are often used in aggressive confrontations that may result in serious, permanent bodily injury or death to those involved. Our CED products may be associated with these injuries. A person, or the family members of a person, injured in a confrontation or otherwise in connection with the use of our products, may bring legal action against us to recover damages on the basis of theories including wrongful death, personal injury, negligent design, defective product or inadequate warning. We are currently subject to a number of such lawsuits and we have been subject to significant adverse judgments and settlements. We may also be subject to lawsuits involving allegations of misuse of our products. If successful, wrongful death, personal injury, misuse and other claims could have a material adverse effect on our operating results and financial condition and could result in negative publicity about our products. We incur significant legal expenses in defending these cases, and significant litigation could also result in a diversion of management’s attention and resources, negative publicity and a potential award of monetary damages in excess of our insurance coverage. The outcome of any litigation is inherently uncertain and there can be no assurance that our existing or any future litigation will not have a material adverse effect on our business, financial condition or operating results.

Other litigation may subject us to significant litigation costs and judgments and divert management attention from our business.

We have been or could in the future be involved in numerous other litigation matters relating to our products, contracts and business relationships, including litigation against persons whom we believe have infringed on our intellectual property, infringement litigation filed against us, litigation against a competitor, enforcement actions filed against us, and litigation involving the U.S. Federal Trade Commission (“FTC”). Such matters have resulted, and are expected to continue to result in, substantial costs to us, including in the form of attorneys’ fees and costs, damages, fines or other penalties, whether pursuant to a judgment or settlement, and diversion of our management’s attention, which could adversely affect our business, financial condition or operating results. There is also a risk of adverse judgments, as the outcome of litigation is inherently uncertain.

We have been, and may be in the future, subject to intellectual property infringement and other claims, which could incur substantial litigation costs, result in significant damage awards, inhibit our use of certain technologies, and divert management attention from our business.

Many companies own intellectual property rights that are directly or indirectly related to public safety technologies. These companies periodically demand licensing agreements or engage in litigation based on allegations of infringement or other violations of their patents, trademarks, copyrights, or trade secrets. Non-practicing entities also have patents they have been granted or otherwise acquired, including patents that are directly or indirectly related to public safety technologies. These entities may seek compensation for perceived infringement of their patents, including by filing claims against us, independent of the merit of any such claims. As we enter new markets, expand into new product categories, and otherwise offer new products, services, and technologies, additional intellectual property claims may be filed against us by these companies, entities, and other third parties. Additional intellectual property claims may also be filed against us as our current products, services, and technologies gain additional market share.

If our products, services, or technologies were found to infringe a third-party’s proprietary rights, we could be forced to discontinue use of the protected technology or enter into costly royalty or licensing agreements in order to be able to sell our products. Such royalty and licensing agreements may not be available on terms acceptable to us or at all. We could also be required to pay substantial damages, fines or other penalties, indemnify customers or distributors, cease the manufacture, use, or sale of infringing products or processes, make proprietary source code

publicly available, and/or expend significant resources to develop or acquire non-infringing technologies. Our suppliers may not provide, or we may not be able to obtain, intellectual property indemnification sufficient to offset all damages, fines or other penalties resulting from any claims of intellectual property infringement brought against us or our customers. There is no guarantee that our use of conventional technology searching and brand clearance searching will identify all potential rights holders. Rights holders may demand payment for past infringements and/or force us to accept costly license terms or discontinue use of protected technology and/or works of authorship that may include, for example, photos, videos, and software. Our current research and development focus on developing software-based products, including that which is related to artificial intelligence or virtual reality, increases this risk.

If we are unable to protect our intellectual property, the value of our brands and products may decrease and we may lose our competitive market advantage.

Our future success depends upon our proprietary technology. Our protective measures for this proprietary technology include patents, trademarks, copyrights, and trade secret protection. However, these protective measures, as well as our efforts to pursue such protective measures, may prove inadequate. For example, the value of intellectual property protection in certain countries may not be apparent until after such protection can no longer be pursued. As such, our intellectual property protection may not extend to all countries in which our products are distributed or will be distributed in the future. Though we work to protect our innovations, we may not be able to obtain protection for certain innovations. For example, we may be unable to patent some software-based products. The scope of any patent protection we have obtained, or may obtain, may not prevent others from developing and selling competing products. Despite our efforts, any intellectual property protection we obtain may be later determined to be insufficient or ineffective.

Our protective measures may prove inadequate for reasons outside of our control. Different intellectual property laws between different countries may lead to differences in protection between such countries. In certain countries in which our products are distributed, the ability to effectively enforce intellectual property rights may not exist. Patent requirements differ by country and certain domestic or foreign laws may prohibit us from satisfying these requirements, creating a risk that some of our international patents may become unenforceable. Patents for older technologies, such as our M26 and X26E models of CEDs, have expired or will expire due to statutory limits on patent term. Despite policies and efforts to maintain secrecy, trade secrets and other confidential information we maintain, or may choose to maintain in the future, could be compromised by employees, partners, or other third parties.

Once established, there is no guarantee that our intellectual property rights will remain in force. Issued patents may be re-examined and subsequently ruled invalid or unenforceable. Our registered trademarks may also be diminished or lost. For example, there is a risk that our “TASER” trademark could become synonymous with the general product category of “conducted energy devices”. The right to stop others from misusing our trademarks and service marks in commerce depends, to some extent, on our ability to show evidence of enforcement of our rights against such misuse in commerce. Our efforts to stop improper use, if insufficient, may lead to loss of trademark and service mark rights, brand loyalty and notoriety among our customers and prospective customers.

Our intellectual property may also be at risk if we are unable to defend from enforcement actions, such as that filed by the FTC against us regarding our acquisition of Vievu LLC from Safariland LLC on May 3, 2018. For additional discussion of this matter, refer to Note 11 to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K. If successful, the FTC is seeking a divestiture of Vievu along with Axon assets sufficient to stand up a viable competitor.

Inability to protect our intellectual property could negatively impact our commercial efforts and competitive market advantage. Regardless of outcome, the prosecution of patent and other intellectual property claims is both costly and time consuming. Unauthorized use of our proprietary technology could divert our management’s attention from our business, and could result in a material adverse effect on our business, financial position, and operating results.

Internationally, we can enforce patent rights only in the jurisdictions in which our patent applications have been granted.

Our U.S. patents protect us from imported infringing products coming into the U.S. from abroad. We have made applications for patents in a few foreign countries; however, these may be inadequate to protect markets for our products in other foreign countries. Each patent is examined and granted according to the law of the country where it was filed independent of whether a U.S. patent on similar technology was granted. A patent in a foreign country may be subject to cancellation if the claimed invention has not been sold in that country. Meeting the requirements of working invention differs by country and ranges from sales in the country to manufacturing in the country. U.S. export law, or the laws of some foreign countries, may prohibit us from satisfying the requirements for working the invention, creating a risk that some of our international patents may become unenforceable.

A variety of new and existing laws and/or interpretations could materially and adversely affect our business.

As detailed in “Business – Government Regulation,” we are subject to a variety of laws and regulations in the United States and abroad that involve matters central to our business, including privacy, data protection and personal information, rights of publicity, content, intellectual property, advertising, marketing, distribution, data security, data retention and deletion, electronic contracts and other communications, competition, consumer protection, telecommunications, product liability, taxation, labor and employment, economic or other trade prohibitions or sanctions, securities law compliance, and online payment services. The introduction of new products, expansion of our activities in certain jurisdictions, or other actions that we may take may subject us to additional laws, regulations, or other government scrutiny. In addition, foreign data protection, privacy, content, competition, and other laws and regulations can impose different obligations or be more restrictive than those in the United States.

These U.S. federal and state and foreign laws and regulations, which in some cases can be enforced by private parties in addition to government entities, are constantly evolving and can be subject to significant change. As a result, the application, interpretation, and enforcement of these laws and regulations are often uncertain and may be interpreted and applied inconsistently from country to country and inconsistently with our current policies and practices. New laws and regulations (or new interpretations of existing laws and regulations) may require us to incur substantial costs, expose us to unanticipated civil or criminal liability, or cause us to change our business practices.

The costs of compliance with these laws and regulation are high and are likely to increase in the future. Additionally, these laws and regulations, or any associated inquiries or investigations or other government actions, may delay or impede the development of new products, result in negative publicity, require significant management time and attention, and subject us to remedies that may harm our business, including fines or demands or orders that we modify or cease existing business practices.

TASER and Axon Devices

For our TASER products, we rely on the opinions of the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, including the determination that a device that does not expel projectiles by the action of an explosive is not classified as a firearm. Changes in statutes, regulations, and interpretation outside of our control may result in our products being classified or reclassified as firearms. If this were to occur, our private citizen market could be substantially reduced because consumers would be required to comply with federal, state, or local firearm transfer requirements prior to purchasing our products.

Federal regulation of sales in the U.S.: Our currently offered CEDs are not firearms regulated by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, but our consumer products are regulated by the U.S. Consumer Product Safety Commission. Although there are currently no federal laws restricting sales of our core currently offered CED products in the U.S., future federal regulation could adversely affect sales of our products.

Our CED products are subject to regulation by testing, safety and other standard organizations. These regulations also affect CEDs with Axon Signal technology, including Signal Performance Power Magazine technology, and TASER 7 battery packs, and could impact future CEDs that feature wireless technology.

Federal regulation of international sales: Our CEDs are considered a “crime control” product by the U.S. DOC for export directly from the U.S. which requires us to obtain an export license from the DOC for the export of our CED devices from the U.S. to any country other than Canada. Future products and services may require classifications from the DOC before they may be shipped internationally. Our inability to obtain DOC export licenses or classifications on a timely basis for sales of our products to our international customers could significantly and adversely affect our international sales.

Federal regulation of foreign national employees: Our intangible CED production is also considered controlled “technology” by the U.S. DOC and is categorized as a “deemed export” for any foreign national employees exposed to the technology within the U.S. Consequently, we must obtain an export licenses from the DOC for any deemed export within the U.S. made to a foreign national employee exposed to the deemed controlled technology. Deemed export licenses are subject to DOC approvals and issued licenses require annual status reports for the stated employees. Inability to obtain proper licensing could curtail the company’s ability to execute R&D and production related to CED technology.

State and local regulation: Our CEDs are controlled, restricted or, less frequently, prohibited by a number of state and local governments. Other jurisdictions may ban or restrict the sale of our CED products, or restrict their use through changes to use-of-force laws or regulations, and our product sales may be significantly affected by additional state, county and city governmental regulation.

International regulation of foreign imports and sales: Certain jurisdictions prohibit, restrict, or require a permit for the importation, sale, possession or use of CEDs, including in some countries by law enforcement agencies, limiting our international sales opportunities.

U.S. and International regulation of component movements globally: We rely on a global supply chain of components across our product lines with most final assembly occurring in the U.S. Export of these components from abroad is subject to shifting regulatory landscapes imposed by both the foreign government and U.S. authorities upon import. Abrupt changes to these regulations can result in delays or interruptions to final product supplies.

International regulation of foreign-based operations: We maintain foreign operations in several countries globally for purposes of logistics, sales, and R&D support. Any failure to properly maintain or license could limit our ability to sell, support, or develop our products and services both internationally and in the U.S. market.

Radio Spectrum Devices

Certain of our products utilize the radio spectrum to provide wireless voice, data and video communications services. The allocation of spectrum is regulated in the U.S. and other countries and limited spectrum space is allocated to wireless services and specifically to public safety users. We manufacture and market products in spectrum bands already made available by regulatory bodies. If current products do not comply with the regulations set forth by these governing bodies, we may be unable to sell our products or could incur penalties. Our results could be negatively affected by the rules and regulations adopted from time to time by the FCC or regulatory agencies in other countries. Regulatory changes in current spectrum bands may also require modifications to some of our products so they can continue to be manufactured and marketed.

Axon body worn cameras, docks, fleet vehicle cameras and signal devices are subject to FCC’s rules and regulations. These regulations affect CEDs with Signal technology, including the TASER 7, SPPM, and future CEDs implementing wireless technology. Compliance with government regulations could increase our operations and product costs and impact our future financial results.

Environmental Regulations

We are subject to various state, federal and international laws and regulations governing the environment, including restricting the presence of certain substances in our products and making us financially responsible for the collection, treatment, recycling and disposal of such products. In addition, further environmental legislation may be

enacted in other jurisdictions, including the U.S. (under federal and state laws) and other countries, the cumulative impact of which could be significant.

We endeavor to comply with applicable environmental laws, yet compliance with such laws could increase our operations and product costs, increase the complexities of product design, procurement, and manufacturing, limit our ability to manage excess and obsolete non-compliant inventory, limit our sales activities, and impact our future financial results. Any violation of the various environmental regulations can subject us to significant liability, including fines, penalties, and prohibiting sales of our products into one or more states or countries and result in a material adverse effect on our financial condition or results of operations.

Privacy Regulations

We are subject to laws and regulations that dictate whether, how, and under what circumstances we can transfer, process and/or receive certain data that is critical to our operations, including data shared between countries or regions in which we operate and data shared among our products and services. If one or more of the legal mechanisms for transferring data from other countries to the U.S. is invalidated, if we are unable to transfer data between and among countries and regions in which we operate, or if we are prohibited from sharing data among our products and services, it could affect the manner in which we provide our services or adversely affect our financial results. Additional countries may pass legislation implementing data protection requirements or requiring local storage and processing of data or similar requirements that could increase the cost and complexity of delivering our services and expose us to significant penalties for non-compliance.

Item 1B.    Unresolved Staff Comments

None.

Item 2.     Properties

Our corporate headquarters and manufacturing facilities are based in an approximately 100,000 square foot facility in Scottsdale, Arizona, which we own. We also lease premises in Phoenix and Scottsdale, Arizona; East Point, Georgia; Charlotte, North Carolina; Topsfield, Massachusetts; Seattle and Spokane, Washington; Melbourne and Sydney, Australia; Toronto, Canada; Daventry and London, England; Tampere, Finland; Frankfurt, Germany; Mumbai, India; Rome, Italy; Amsterdam, Netherlands; and Ho Chi Minh City, Vietnam. In 2020, we purchased a parcel of land located in Scottsdale, Arizona on which we intend to construct a new manufacturing and office facility.

We believe our existing facilities are well maintained and in good operating condition. We also believe we have adequate manufacturing capacity for our existing product lines. To the extent that we introduce new products in the future, we will likely need to acquire additional facilities to locate the associated production lines. However, we believe we can acquire or lease such facilities on reasonable terms. We continue to make investments in capital equipment as needed to meet anticipated demand for our products.

The majority of our locations support both of our reportable segments, except for our Vietnam and Seattle, Washington locations, which primarily support our Software & Sensors segment.

Overview

Axon is a global network of devices, apps and people that helps public safety personnel become smarter and safer. With a mission of protecting life, our technologies give law enforcement the confidence, focus and time they need to protect their communities. Our products impact every aspect of a public safety officer’s day-to-day experience with the goal of helping everyone get home safe.

Our revenues for the year ended December 31, 2021 were $863.4 million, an increase of $182.4 million, or 26.8%, from the prior year. We had a loss from operations of $168.1 million compared to $14.2 million in the prior year. The higher loss from operations was primarily the result of increased stock compensation expense for our CEO Performance Award and XSPP. In addition, operating expenses were higher in 2021 primarily due to an increase in headcount; these other cost increases were largely offset by higher revenue. For the year ended December 31, 2021, we recorded net loss of $60.0 million compared to net loss of $1.7 million for the prior year.

2022 Outlook

For the year ending December 31, 2022, we expect revenue of approximately $1 billion. We anticipate capital expenditures of approximately $135 million to $160 million in 2022, including approximately $85 million for development of our manufacturing facility and campus in Scottsdale, Arizona, approximately $40 million to support capacity expansion and automation of TASER devices, and the remainder on additional investments to support our continued growth.

COVID-19

The COVID-19 pandemic has adversely affected workforces, economies, and financial markets globally, and led to an economic downturn. As an essential provider of products and services for law enforcement and other first responders, we remain focused on protecting the health and wellbeing of our employees while assuring the continuity of our business operations.

We have taken a number of actions in response to the pandemic:

Employee safety and manufacturing:

​

Supply chain:

​

Shareholder engagement:

Results of Operations

The following table presents data from our consolidated statements of operations as well as the percentage relationship to total net sales of items included in our statements of operations (dollars in thousands):

​

​

Net sales to the U.S. and other countries are summarized as follows (dollars in thousands):

​

​

International revenue in 2021 increased compared to 2020, driven by strength in all of our international regions, particularly in the Americas and EMEA regions.

Our operations are comprised of two reportable segments: the manufacture and sale of CEDs, batteries, accessories and extended warranties and other products and services (collectively, the “TASER” segment); and software and sensors, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the "Software and Sensors" segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the TASER segment, service revenue also includes digital subscription training content. In the Software and Sensors segment, service revenue also

includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue." Revenue from our “products” in the Software and Sensors segment are generally from sales of sensors, including on-officer body cameras, Axon Fleet cameras, other hardware sensors, warranties on sensors, and other products, and is sometimes referred to as "Sensors and Other revenue." Within the Software and Sensors segment, we include only revenues and costs attributable to that segment which costs include: costs of sales for both products and services, direct labor, and product management and R&D for products included, or to be included, within the Software and Sensors segment. All other costs are included in the TASER segment.

For the Years Ended December 31, 2021 and 2020

Net Sales

Net sales by product line were as follows for the years ended December 31, 2021 and 2020 (dollars in thousands):

​

​

Net unit sales were as follows:

​

​

Net sales for the TASER segment increased $70.4 million, or 19.2%, primarily as a result of an increase of $37.6 million in cartridge revenue and a $28.4 million increase in TASER 7 devices. Cartridge revenue increased due to

increased unit sales. Consumer devices revenue decreased $2.3 million or 24.2% driven by a decrease in retail sales due to a shift in consumer shopping behaviors, as well as lower average selling prices, and higher sales during the prior year due to civil unrest. We continue to see a shift to purchases of our latest generation device, TASER 7, from legacy devices, especially X26P devices. Sales of our TASER 7 device also drove the increase in revenue from Axon Evidence and cloud services. Revenue was also impacted by higher average selling prices for TASER devices other than TASER consumer devices. TASER 7 revenue for 2021 was impacted by approximately $35.0 million for orders that were scheduled to ship prior to December 31, 2021, but could not be fulfilled due to the delayed receipt of a manufacturing component for our TASER 7 devices. We expect to recognize this revenue during the first half of 2022.

Net sales for the Software and Sensors segment increased $112.0 million, or 35.6%. Revenue from Axon Evidence and cloud services increased $69.2 million as we continued to add users and associated devices to our network during the year ended December 31, 2021. The increase in the aggregate number of users and devices also resulted in increased extended warranty revenues of $9.3 million. Sales of our Axon Body 3 camera drove most of the $18.3 million increase in Axon Body revenue and the $4.7 million increase in Axon Dock revenue. Other revenue increased $6.2 million or 50.7% due to increases in signal sidearm and signal performance power magazine (SPPM) attributable to increased sales of our TASER 7 devices. Axon Body revenue was impacted by approximately $15.5 million for orders that were scheduled to ship prior to December 31, 2021, but could not be fulfilled due to supply chain constraints for our Axon Body 3 devices. We expect to recognize this revenue during the first half of 2022.

Backlog - As of December 31, 2021 compared to December 31, 2020

Our backlog for products and services includes all orders that have been received and are believed to be firm.

In the TASER segment, we define backlog as equal to deferred revenue. Deferred revenue represents amounts invoiced to customers for goods and services to be delivered in subsequent periods. We process orders within the TASER segment quickly, and our best estimate of firm orders outstanding as of period end represents those that have been invoiced but remain undelivered. The TASER segment backlog balance was $73.9 million as of December 31, 2021. We expect to realize $36.9 million of this deferred revenue balance as revenue during the next 12 months. This represents cash received and accounts receivable from customers on or prior to December 31, 2021 for products and services expected to be delivered in the next 12 months.

In the Software and Sensors segment, we define backlog as cumulative bookings, net of cancellations, less product and service revenue recognized to date. Bookings are generally realized as revenue over multiple years. The Software and Sensors backlog balance was $2.4 billion as of December 31, 2021. This backlog balance includes $377.4 million of deferred revenue, and $2.0 billion that has been recorded as bookings but not yet invoiced, all as of December 31, 2021. We expect to realize approximately $510.8 million of the December 31, 2021 backlog balance as revenue during the next 12 months.

​

​

Our backlog of $2.4 billion as of December 31, 2021 has increased significantly from $1.5 billion as of December 31, 2020. The increase in TASER segment backlog is not expected to have a material impact on revenue or operating margins. Our significant increase in backlog, primarily in the Software and Sensors segment is indicative of expected revenue growth in this segment.

Cost of Product and Service Sales

Cost of product and services sales in dollars and as a percent of related segment sales (dollars in thousands):

​

​

Within the TASER segment, cost of product and service sales was $149.9 million, an increase of $13.0 million, or 9.5%, from 2020. Cost as a percentage of sales decreased to 34.3% from 37.4%. The improvement was primarily attributable to a combination of manufacturing cost improvement and strong demand for our premium TASER offerings, which resulted in a favorable product mix. We are building manufacturing capacity to support our TASER device and cartridge manufacturing lines in response to growing international and federal demand and an increased install base.

Within the Software and Sensors segment, cost of product and service sales was $172.6 million, an increase of $44.8 million, or 35.1%, from 2020. As a percentage of net sales, cost of product and service sales decreased slightly to 40.5% in 2021 from 40.6% in 2020. Cost of product sales increased $23.2 million primarily driven by the impact of increased units, but decreased as a percentage of sales due to the fulfillment of several large shipments of lower-margin body camera hardware to our largest customers during the prior year. Cost of service sales increased $21.7 million and increased as a percentage of sales. We are investing in scaling our cloud business, which includes standing up new cloud environments, cloud applications, and Long-Term Evolution (“LTE”) costs, which can result in some margin compression in advance of anticipated revenue, as well as low-to-no margin professional services that support new installations for software customers.

Gross Margin

Gross Margin (dollars in thousands):

​

​

Gross margin increased $124.6 million to $540.9 million for the year ended December 31, 2021 compared to $416.3 million for 2020. As a percentage of net sales, gross margin increased to 62.7% for 2021 from 61.1% for 2020.

As a percentage of net sales, gross margin for the TASER segment increased to 65.7% for the year ended December 31, 2021 from 62.6% for the year ended December 31, 2020.

Within the Software and Sensors segment, gross margin as a percentage of total segment net sales was 59.5% and 59.4% for the years ended 2021 and 2020, respectively. Within the Software and Sensors segment, product gross

margin was 39.2% for the year ended December 31, 2021 and 36.6% for the same period in 2020, while the service margins were 74.6% and 77.1% during those same periods, respectively.

Sales, General and Administrative Expenses

Sales, General and Administrative ("SG&A") Expenses (dollars in thousands):

​

​

SG&A expenses increased $207.7 million, or 67.6%. Stock-based compensation expense increased $135.0 million in comparison to the prior year comparable period, which was attributable to an increase of $137.9 million in expense related to the CEO Performance Award and XSPP, partially offset by a decrease of $1.9 million related to PSUs for certain key employees and executives that fully vested in March 2021. As of December 31, 2021, all twelve operational goals for the CEO Performance Award and XSPP are considered probable of attainment or have been attained; during the prior year comparable period, eleven operational goals were considered probable. Refer to Note 14 of the notes to our consolidated financial statements within this Annual Report on Form 10-K for additional discussion of the CEO Performance Award and XSPP.

Salaries, benefits and bonus expense increased $56.8 million, primarily due to an increase in headcount and an increase in payroll taxes on a higher base of salaries and bonus expense. Salaries, benefits and bonus expense increased as a percentage of sales from 12.2% for 2020 to 16.2% for 2021.

Sales and marketing expenses increased $19.6 million, driven by a $10.5 million increase in commissions tied to higher revenues, and by higher spending on advertising, sponsorships, and customer samples. Included in this increase was $3.4 million related to trade shows and seminars, including our inaugural VR roadshow and $1.0 million attributable to our annual Axon Accelerate user conference being held in-person.

Professional, consulting and lobbying expenses decreased $11.2 million, driven primarily by a decrease of $18.3 million in expenses related to the FTC litigation. As discussed in Note 11 of the notes to our consolidated financial statements within this Annual Report on Form 10-K, we sued the FTC in the District of Arizona, and the FTC filed an enforcement action regarding our May 2018 acquisition of Vievu LLC. Offsetting the decrease in legal expenses was an increase in other professional and consulting expenses for costs related to the implementation of several phases of our enterprise resource planning and related systems.

Other SG&A expenses increased by $7.6 million, primarily driven by the following:

​

Research and Development Expenses

Research and Development ("R&D") Expenses (dollars in thousands):

​
