PART I

Item 1. Business

Overview

For 25 years, Akamai has developed and provided solutions to power and protect life online through our massively distributed worldwide network of servers. This platform, which we recently began referring to as the Akamai Connected Cloud is comprised of an edge and cloud architecture for cloud computing, security and content delivery. The Akamai Connected Cloud provides us with visibility and insight into traffic volumes, congestion, attack patterns, vulnerabilities and other activities across the internet's complex intersections of networks and systems. Leveraging these insights, the Akamai Connected Cloud offers solutions designed to protect our customers from threats and attacks, while empowering them to securely deliver their business as they engage, entertain and interact with their customers; and extend their internal systems beyond their corporate perimeters to control access and better leverage the cloud by efficiently building, deploying and securing performant workloads that require single-digit millisecond latency and global reach.

After multiple years of the COVID-19 pandemic, which shifted how millions of people work and communicate globally, we firmly believe that the internet’s role in transforming the way we exchange ideas and information and conduct business is more vital than ever. Our strategy is to help continue to drive this transformation by offering compute, security and content delivery services on Akamai Connected Cloud that empower our customers to compete and operate with the scale, resilience and efficiency that their businesses demand. Our platform spans more than 350,000 servers in over 4,100 locations, with roughly 1,300 network partners. We are planning to significantly increase the number of core and distributed cloud computing sites on our platform in order to continue the expansion of our cloud computing services.

Our Solutions

We provide solutions in three core categories: security, content delivery and compute. We also provide solutions for carriers and certain services and support for our customers as they utilize our core solutions.

Security

Our cloud security solutions are designed to keep infrastructure, websites, applications, application programming interfaces ("APIs"), and users safe from a multitude of cyberattacks and online threats while improving performance. Our solutions blend robust automation with customizable protections and managed security services to enable businesses to effectively manage risk and maximize the protections of their infrastructure, networks, applications and APIs. Akamai’s cloud security solutions include web application and API protection, bot management and mitigation to protect against credential abuse and account takeover, customer identity and access management, distributed denial of service ("DDoS") mitigation, protection from in-browser threats to protect against supply chain compromise and audience hijacking. We also offer a growing set of solutions designed to help businesses implement a “zero trust” approach to security. Based on the concept of least privilege, which dictates that users, applications and services utilize the bare minimum amount of access needed to perform their function, these tools are intended to shift protections from a legacy approach based on establishing a corporate perimeter, to a more modern,

3

risk-based approach. Solutions in this category include Zero Trust Network Access ("ZTNA"), and multi-factor authentication ("MFA"), which replace legacy virtual private networks ("VPNs"), micro-segmentation which replaces legacy network firewalls and helps protect businesses from the threat of ransomware and Secure Web Gateway ("SWG"), that helps protect against the threat of malware and phishing attacks.

Our acquisition of Guardicore Ltd. ("Guardicore") in late 2021 was a significant milestone in positioning Akamai as a leader in technology that powers and protects life online. Guardicore’s microsegmentation solution helps our customers prevent malicious lateral movement in their network through precise segmentation policies, visuals of activity within their IT environment and network security alerts.

Content Delivery

Our web and mobile performance solutions are architected to enable dynamic websites and applications to have rapid response times, no matter where the user is, what device or browser they are using or how they are connected to the internet. These services leverage intelligent performance optimization and real-time monitoring, origin offload and network reliability, and insights that enable enterprises to identify and address performance issues. Akamai web and mobile performance capabilities also include global traffic management, site acceleration, application load balancing, large-scale load testing and real-user monitoring.

Our media delivery solutions are designed to enable enterprises to execute their digital media distribution strategies by addressing volume and global reach requirements, improving the end-user experience, boosting reliability and reducing the cost of internet-related infrastructure. Underlying these solutions is technology to address variable connection speeds and device types, facilitate access to disparate locations around the world, accelerate large file downloads, reliably deliver high-quality live content across various devices and platforms, and enable comprehensive insights and real-time online video monitoring. Akamai media delivery solutions include video streaming and video player services, game and software delivery, broadcast operations, authoritative domain name system ("DNS"), resolution and data and analytics.

Compute

Akamai cloud computing services (which we sometimes refer to as "Compute") include compute, storage, networking, database and container management services that are required to build, deploy and secure applications and workloads. The cloud computing services running on the Akamai Connected Cloud enable companies to distribute workloads and applications across our core to edge infrastructure to help solve the cost, performance and scale that centralized cloud computing platforms present today.

In early 2022, Akamai acquired Linode Limited Liability Company ("Linode"), an established cloud computing platform. This acquisition was a significant milestone in our expansion into cloud computing services. While Linode was traditionally focused on individual developers, we are looking to leverage the Linode cloud computing services for enterprise customers by building new enterprise-grade core and distributed sites and connecting them to the Akamai backbone, which we believe will give Akamai an advantage over its bigger cloud rivals. While many other cloud providers are building their cloud platforms based on a regional, data center-centric model, Akamai is designing its cloud based on the fundamental belief that modern applications will be comprised of workloads that will be distributed across a continuum of computing sites that meet the specific needs of that workload.

Carrier

Our carrier offerings are designed to help customers operate a cost-efficient network that capitalizes on traffic growth and new subscriber services for security, traffic management and content delivery. Our solutions help carriers sell easy-to-deploy cybersecurity protection offerings to their subscriber base; offerings include protection from phishing, viruses, malware and ransomware. Additionally, our carrier security solutions include parental controls to tailor internet access. We also offer DNS infrastructure and content delivery solutions for carriers through our intelligent recursive DNS offering and managed content delivery network, which has dedicated servers for the carriers’ own services with Akamai providing content provisioning, delivery and reporting.

Services and Support

We provide an array of service and support offerings designed to assist customers with integrating, configuring, optimizing and managing our core offerings. Once customers are deployed on the Akamai Connected Cloud, they can rely on our

4

professional services and security experts for customized solutions, problem resolution and 24/7 customer support. Additional features are available to enterprises that purchase our premium and managed security solutions including a dedicated technical account team, proactive service monitoring, custom technical support handling, security traffic monitoring, technical security reviews, threat advisories and emergency support for security events.

Human Capital

Our employees – our human capital – are our most valuable resources as they are fundamental to our innovation, the operation and ongoing enhancement of the Akamai Connected Cloud, the fostering and maintenance of relationships with our customers and the management of our operations. The importance of our workforce to our success is underscored by the inclusion of corporate mission critical goals centered on our employees – in 2022 we focused on further developing an inclusive, diverse, productive and flexible work environment by embracing the future of work, and on putting our culture and our purpose into action by applying a growth mindset to creatively and collaboratively solve our toughest challenges. Different aspects of our human capital management are overseen by our board of directors as well as its Talent, Leadership & Compensation and Environmental, Social & Governance Committees.

As of December 31, 2022, we had over 9,800 employees located in more than 30 countries (with approximately 60% of those employees located outside of the U.S.) and representing over 95 nationalities, which we believe helps bring a global perspective to our operations. Our employees are grouped across the following roles, with the approximate percentage of the overall population noted: engineering and research and development (33%), services and support (28%), sales and marketing (19%) and administrative functions (20%).

Engagement

We continue to believe that an engaged employee workforce is key to having the productive, ethical and high-performing workplace needed to successfully compete in today’s marketplace. We conduct quarterly surveys of our employees to assess a variety of key metrics related to key topics, such as engagement, inclusion and job satisfaction. Results from these surveys have consistently shown a strong sense of engagement and confidence in Akamai’s future; as Akamai, in 2022, outperformed the high performing benchmark comparative index used by our third-party survey provider, an internationally-recognized consulting firm specializing in corporate culture. We have been acknowledged in respected publications across the U.S., India and Poland as a great place to work. Continuing in 2022, all employees were invited to participate in a company-wide program, developed by a behavioral research organization, that was intended to help us increase inclusivity, become more open to change and accelerate our innovation. In addition, we work closely with the Akamai Foundation to provide community service and charitable matching fund opportunities for Akamai employees, endeavors that have been shown to increase employee engagement. In 2022, the Akamai Compassion Fund, created by employees for employees with support from the Akamai Foundation, was established as a way for Akamai employees to unite and support global colleagues and their families during times of unexpected hardships following a catastrophic event.

Diversity

Akamai is an equal opportunity employer that values the strength that diversity brings to the workplace. We do not tolerate discrimination on the basis of gender, gender identity, sexual orientation, race or ethnicity, protected veteran status, disability or other protected group status. Akamai supports varied programs and practices designed to promote a diverse and inclusive working environment. We have nine employee resource groups ("ERGs") that offer opportunities for employees to come together for mutual support, education and development. ERGs encompass different racial and ethnic groups, persons with different physical or cognitive abilities, parents, military veterans, the LGBTQIA+ community and women. We track the diversity of our workforce and report quarterly to the board of directors on our progress to improve our representation. At December 31, 2022, global female representation was 27.2%, down slightly from 27.3% at the end of 2021. Racial and ethnic minority representation in the U.S. was 40.3%, down from 41.4% at the end of 2021; however, since the end of 2021 our Black representation and Hispanic representation have both increased. To help us improve the diversity of our workforce, we participate in or sponsor professional development and recruiting forums. We also train hiring managers to draft inclusive job descriptions intended to broaden the pool of eligible applicants.

5

Retention

We have a demonstrated history of investing in our workforce by offering competitive salaries, wages and benefits. Our compensation and benefits philosophy is to maximize the effectiveness of pay and benefits programs to attract and retain the high caliber individuals needed to drive the success of our business, while balancing cost-effectiveness and competitive factors. Our benefits programs (which vary by country and region) include healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, family care resources, flexible work schedules and locations, adoption and fertility assistance, employee assistance programs, tuition assistance and holistic wellness programs. Our wellness programs include educational offerings on healthy lifestyles, access to mental health experts and access to ergonomic advice and equipment. To foster a stronger sense of ownership and align the interests of employees with shareholders, restricted stock units are held by the vast majority of our employees under our broad-based stock incentive programs, and most employees are eligible to participate in our employee stock purchase plan. We monitor voluntary attrition in assessing our overall human capital. Attrition was slightly down in 2022 when compared to 2021, and, we believe our attrition rate is significantly lower than the global average for technology companies.

As a signatory to the White House Equal Pay Pledge, we are committed to monitoring our pay practices regularly and making adjustments, as necessary, to deliver on this pledge. We currently conduct bi-annual internal pay equity analyses (with the assistance of a nationally-recognized outside consultant), covering gender globally and race and gender in the U.S. We take action to remedy identified discrepancies as appropriate. To date, no widespread patterns of disparity have been identified.

In addition, succession planning is an ongoing priority for our leadership. We conduct annual succession planning for senior leadership, which is overseen by our board of directors, including development plans for the next level of our senior leaders. Annual talent reviews focus on both high performers as well as those with high potential to keep our pipeline of tomorrow’s leaders full.

Development

We invest significant resources in professional development, career advancement and training for our global workforce. All employees participate in our Akamai Elevation performance review program, which provides guidance around setting objectives, developing competencies and receiving feedback. For select employees, we offer leadership training workshops, 360-degree feedback and succession planning exercises to encourage and enable internal promotion and advancement. As a result of these investments and others, approximately 21% of open positions were filled with internal candidates in 2022. All employees are required to complete annual ethics and compliance and data security training. In addition to these required trainings, nearly all of our employees and contractors completed at least one training in our Akamai University program during 2022.

FlexBase

In May 2022, we launched FlexBase, which is a flexible workspace arrangement that allows over 95% of employees to choose to work from their home office, a Company office or a combination of both. This is a significant change to the way employees worked prior to the program, and prior to office shutdowns as part of the COVID-19 pandemic. We believe that flexible workforce positions and a focus on employee choice, will make us a more attractive employer, increase productivity, enable us to recruit from a more diverse pool of applicants and present additional growth and development opportunities for our employees. Throughout 2022, we rolled out a number of tools and resources to support this program, such as supporting employees with guidance on maximizing our internal tools to deliver great virtual meeting experiences.

Customers

Our customers include many of the world's leading corporations, such as Adobe, Airbnb, Alibaba, Autodesk, Capital Group, Carnival Corporation, The Coca-Cola Company, Comcast, Crate & Barrel, eBay, Electronic Arts, Epic Games, FedEx, Fidelity Investments, Honda, IKEA, Japan Airlines, Lufthansa, Maersk Transportation & Logistics, Marriott, NBCUniversal, Panasonic, Panera Bread, PayPal, Philips, Rabobank, Riot Games, Sony Interactive Entertainment, Spotify, Telefonica, Toshiba, Ubisoft, Viacom, WarnerMedia and The Washington Post. We also actively sell to government agencies. As of December 31, 2022, our public-sector customers included the U.S. Census Bureau, the U.S. Department of Defense, the U.S. Department of Labor, the U.S. Department of State, the U.S. Department of Transportation and the U.S. Department of the Treasury.

6

No customer accounted for 10% or more of total revenue for any of the years ended December 31, 2022, 2021 and 2020. Less than 10% of our total revenue in each of the years ended December 31, 2022, 2021 and 2020 was derived from contracts or subcontracts terminable at the election of the federal government, and we do not expect such contracts to account for more than 10% of our total revenue in 2023.

Sales, Services and Marketing

We market and sell our solutions globally through our direct sales and services organization and through many channel partners, including AT&T, Deutsche Telecom, Kyndryl, IBM, Microsoft, Orange Business Services and Telefonica Group. In addition to entering into agreements with resellers, we have several other types of sales and marketing focused alliances with entities such as system integrators, application service providers, referral partners and sales agents. By aligning with these partners, we believe we are better able to market our solutions and encourage increased adoption of our technology throughout the industry. Our sales, services and marketing professionals are based in locations across the Americas, Europe, the Middle East and Asia-Pacific and focus on direct and channel sales, sales operations, professional services, account management and technical consulting.

To support our sales efforts and promote the Akamai brand, we conduct comprehensive marketing programs. Our marketing strategies include an active public relations campaign, print advertisements, online advertisements, participation at trade shows (virtually or in person), strategic alliances, ongoing customer communication programs, training and sales support.

Competition

The market for our solutions is intensely competitive and characterized by rapidly changing technology, evolving industry standards and frequent new product and service innovations. We expect competition for our offerings to increase both from existing competitors and new market entrants. We compete primarily on the basis of:

•the performance and reliability of our solutions;

•return on investment in terms of cost savings and new revenue opportunities for our customers;

•reduced infrastructure complexity;

•sophistication and functionality of our offerings;

•scalability;

•security;

•ease of implementation, distribution of our network and use of service;

•customer support; and

•price.

We compete with companies offering products and services that address internet performance problems, including companies that provide internet content delivery and hosting services, security and cloud computing solutions, technologies used by carriers to improve the efficiency of their systems, streaming content delivery services and equipment-based solutions for internet performance problems, such as load balancers and server switches. Other companies offer online distribution of digital media assets through advertising-based billing or revenue-sharing models that may represent an alternative method for charging for the delivery of content and applications over the internet. In addition, existing and potential customers may decide to purchase or develop their own hardware, software or other technology solutions rather than rely on a third-party provider like us. Our security solutions compete with those offered by both hardware and software providers, many of which are more established security vendors than we are. While our Linode based solutions have historically competed with alternative cloud computing platforms focused on individual developers, we anticipate that going forward our cloud computing solutions will increasingly compete with the large so-called “hyper-scaler” cloud computing providers.

We believe that we compete favorably with other companies in our industry through the global scale of the Akamai Connected Cloud, which we believe provides the most effective means of meeting the needs of enterprise customers and is unique to us. In our view, we also benefit from the high quality of our offerings, our customer service and the information we can provide to our customers about their online operations and value.

Government Regulation

As a global technology company, Akamai is subject to complex foreign and U.S. laws and regulations in areas such as data privacy and localization, liability for content delivered over our network, bribery, sanctions, export controls, competition, tax and foreign exchange controls.

7

Privacy laws, such as the European Union General Data Protection Regulation and the California Consumer Privacy Act of 2018, impact how we use data generated from our network as well as our ability to reach current and prospective customers, understand how our solutions are being used, transfer data about our employees and respond to customer requests allowed under the laws. Other laws and regulations that apply to the internet related to, among other things, content liability, security requirements, critical infrastructure designations, internet resiliency, law enforcement access to information, net neutrality, so-called "fair share" or internet content taxes, data localization requirements, industry regulations applicable to key suppliers to some of our customers and restrictions on social media or other content can have an impact on our business. For instance, regulations have been enacted or proposed in a number of countries that limit the delivery of certain types of content into those countries. As an example, restrictions were adopted in India in 2020 prohibiting access to identified Chinese applications. Enactment and expansion of such laws and regulations in other jurisdictions would negatively impact our revenues or cause us to incur costs to redesign our systems to ensure compliance.

We are subject to the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. To the extent we export technical services, data, products or other technology outside of the U.S., we are subject to U.S. and international laws and regulations governing international trade and exports, including, but not limited to, the International Traffic in Arms Regulations, the Export Administration Regulations and sanctions against embargoed countries.

Many of these laws and regulations are evolving and could be interpreted and applied in a manner that is inconsistent from country to country and inconsistent with our current policies and practices and in ways that could harm our business. For example, while we are generally not subject to regulations applicable to telecommunications companies, new or different interpretations of laws or regulations could subject us to regulatory supervision. In general, the nature and breadth of laws and regulations governing the internet may increase in the future; accordingly, we are unable to assess the possible effect of compliance with future requirements or whether our compliance with such regulations will materially impact our business, results of operations or financial condition.

For further discussion of how government regulations may affect our business, see the related discussion below in Item 1A. Risk Factors – Financial and Operational Risks – We face risks associated with global operations that could harm our business; – Legal and Regulatory Risks – Evolving privacy regulations could negatively impact our profitability and business operations; and – Legal and Regulatory Risks – Other regulatory developments could negatively impact our business.

Intellectual Property

Our success and ability to compete are dependent on developing and maintaining the proprietary aspects of our technology and operating without infringing on the proprietary rights of others. We rely on a combination of patent, trademark, trade secret and copyright laws and contractual restrictions to protect the proprietary aspects of our technology. As of December 31, 2022, we owned, or had exclusive rights to, over 520 U.S. patents covering our technology as well as patents issued by other countries. Our U.S.-issued patents have terms extendable to various dates between 2023 and 2041. We do not believe that the expiration of any particular patent in the near future would be materially detrimental to our business. We seek to limit disclosure of our intellectual property by requiring employees and consultants with access to our proprietary information to execute confidentiality agreements with us and by restricting access to our source code.

Additional Information

Our internet website address is www.akamai.com. We make available, free of charge, on or through our internet website, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments thereto that we have filed or furnished with the Securities and Exchange Commission (the "Commission") as soon as reasonably practicable after we electronically file them with the Commission. We are not, however, including the information contained on our website, or information that may be accessed through links on our website, as part of, or incorporating such information by reference into, this annual report on Form 10-K.

Item 1A. Risk Factors

The following are important factors that could cause our actual operating results to differ materially from those indicated or suggested by forward-looking statements made in this annual report on Form 10-K or presented elsewhere by management from time to time.

Financial and Operational Risks

We may face slowing revenue growth which could negatively impact our profitability and stock price.

The revenue growth we have enjoyed in recent years may not continue in future periods and could decline, which could negatively impact our profitability and stock price. Our revenue depends on the amount of services we deliver, continued growth in demand for our delivery, compute and security solutions and our ability to maintain the prices we charge for them. In particular, varying levels of the amount of traffic on our network can have a significant impact on our short-term revenue growth rate.

We experienced a significant increase in revenue from our delivery solutions in 2020 due in large part to greater consumption of online media and games during the onset of the COVID-19 pandemic and associated stay-at-home orders across the globe. In 2021 and 2022, our revenue growth from delivery solutions declined as stay-at-home orders were lifted. Numerous factors impact our revenue, traffic and sales growth including:

•our ability to build on recurring revenue commitments for our security, compute and delivery offerings;

•our ability to develop new products;

•the pace of introduction of over-the-top video delivery initiatives by our customers;

•the popularity of our customers’ streaming offerings as compared to those offered by other companies;

•factors that impact the pricing and unit pricing we can obtain for our offerings;

•variation in the popularity of online gaming;

•customers utilizing their own data centers and implementing solutions that limit or eliminate reliance on third-party providers like us;

•the adoption of permanent hybrid or work from home policies by employees; and

•general macroeconomic, regulatory and geopolitical conditions, including the war in Ukraine, and industry pressures.

We have experienced significant growth in revenue from our security and compute solutions in recent years. If we do not increase our industry recognition as a security and compute solutions provider, develop or acquire new solutions in a rapidly-changing environment where security threats are constantly evolving or ensure that our solutions operate effectively and are competitive with products offered by others, our security or compute revenue, or both, may decline.

We are dependent upon the overall economic health of our current and prospective customers and the continued growth and evolution of information technology. We have experienced revenue declines in recent quarters for portions of our business that include our delivery-based solutions and expect this trend to continue because of continued pricing pressure due to competition and fluctuations in traffic growth rates. For example, approximately 1% of our 2021 revenue had been generated from traffic into Russia, Belarus and Ukraine, and we experienced a decline in revenue in 2022 related to the war in Ukraine due to a decrease in traffic in these countries. In addition, in 2021 and 2022, some of our customers continued to experience disruptions to their businesses following the emergence of COVID-19 variants. These disruptions or changes in international, national, regional and local economic conditions could adversely affect our business. Any of these circumstances would negatively impact our revenues.

Our ability to increase our overall revenue also depends on many other factors including how well we can:

•retain existing customers, including by maintaining the levels of existing services they buy and by delivering consistent and quality performance levels;

•upsell new solutions to existing customers;

•expand our customer base;

•develop and sell innovative and appealing new solutions;

•continue to expand our sales internationally;

•successfully integrate our recent acquisitions into our business;

•address potential commoditization of certain of our solutions, which can lead to lower prices and loss of customers to competitors;

•maintain pricing and make decisions on pricing strategy;

9

•successfully manage the sales cycle, including improving the ability of or pace at which our customers or prospects purchase new services and solutions;

•counteract multi-vendor policies that could cause customers to reduce their reliance on us;

•handle other competitive threats to our business;

•adapt to changes in our customer contracting models from a committed revenue structure to a "pay-as-you-go" approach, which would make it easier for customers to stop doing business with us, or from traditional overage billing models to ones that do not incorporate surcharges for usage above committed levels; and

•manage the impact of changes in general economic conditions, geopolitical conditions, industry pressures, public health issues, natural disasters and public unrest on our ability to sell, market and provide our solutions.

If we are unable to increase revenues, our profitability and stock price could suffer.

Global economic and geopolitical conditions may harm our industry, business and results of operations.

We operate globally and as a result, our business, revenues and profitability are impacted by global macroeconomic conditions. The success of our activities is affected by general economic and market conditions, including, among others, inflation, interest rates, tax rates, economic uncertainty, political instability, warfare, changes in laws, trade barriers, reduced consumer confidence and spending and economic and trade sanctions. The U.S. capital markets experienced and continue to experience extreme volatility and disruption following the global outbreak of COVID-19 in 2020 and the Russian invasion of Ukraine in 2022. Furthermore, inflation rates in the U.S. have recently increased to levels not seen in decades. Such economic volatility could adversely affect our business, financial condition, results of operations and cash flows, and future market disruptions could negatively impact us. These unfavorable economic conditions could increase our operating costs, which could negatively impact our profitability. Geopolitical destabilization and warfare have impacted and could continue to impact global currency exchange rates, resources from our suppliers, and ability to operate or grow our business. For example, as a result of the recent uncertain macroeconomic environment, we have experienced elongated sales cycles with our customers and prospects and customers are delaying purchases of our solutions.

Additionally, we have offices and employees located in regions that historically have and may experience periods of political instability, warfare, changes in laws, trade barriers, and economic and trade sanctions. Adverse conditions in these countries directly affect our operations. As a result, our operations and employees could be disrupted and may not be able to function at full capacity, which could adversely affect our business, results of operations, financial condition, and cash flows.

Failure to control expenses could reduce our profitability, which would negatively impact our stock price.

Maintaining or improving our profitability depends both on our ability to increase our revenue, even with the potential challenges discussed above, and limit our expenses. We base our decisions about expense levels and investments on estimates of our future revenue and future anticipated rates of growth; however, many of our expenses are fixed costs for a certain amount of time so it may not be possible to reduce costs in a timely manner or without incurring fees to exit certain obligations early. In addition, we have seen our costs increase and our costs may continue to increase due to rising inflation, increasing cost of labor, interest rates, supply chain disruptions or other market conditions. For example, we have experienced rising energy costs in areas in which we operate, particularly in Europe. If we are unable to increase revenue through traffic growth, growth of sales of our products and services or otherwise and limit expenses, our results of operations will suffer. We may take certain steps to reduce expenses, but there are no assurances that we will be able to effectively reduce our expenses. If we are required to further reduce expenses to maintain or improve profitability, such actions may negatively affect our ability to invest in our business for innovation, systems improvements and other initiatives.

If we do not develop or acquire new solutions that are attractive to our customers, our revenue and operating results could be adversely affected.

Innovation is important to our future success. In particular, as security and compute solutions have become, and are expected to continue to be, an increasingly important part of our business, we must be particularly adept at developing new security and compute services that meet the constantly-changing threat landscape. In addition, we must continue to develop compute and compute-to-edge solutions that meet the needs of professional users and enterprises looking to increase the utility of the internet for their business.

The process of developing new solutions and product enhancements is complex, lengthy and uncertain and has become increasingly complex due to the sophistication and the addressing of our customers’ needs. The development timetable to commercial release is uncertain and we must commit significant resources to developing new services or features without knowing whether our investments will result in solutions the market will accept, and we may choose to invest in business areas

10

for which a viable market for our products does not ultimately develop. For example, with the recent acquisition of Linode, we are focused on investing in our suite of cloud computing products. We have invested significant resources toward integrating Linode into our edge platform, including connecting Linode’s existing locations into our private backbone, working on expanding the capacity of these facilities and adding additional sites. Success in these efforts is not guaranteed and will largely depend on our ability to create products that are competitive in the enterprise market, source additional co-location facilities and manage an uncertain supply chain for server related hardware. In addition, we have also experienced, and may in the future experience, delays in developing and releasing new products and product enhancements. This could cause our expenses to grow more rapidly than our revenue.

Trying to innovate through acquisition can be costly and with uncertain prospects for success; we may find that attractive acquisition targets are too expensive for us to pursue which could cause us to pursue more time-consuming internal development.

Failure to develop, on a cost-effective basis, innovative new or enhanced solutions that are attractive to customers and profitable to us could have a material detrimental effect on our business, results of operations, financial condition and cash flows.

If we are unable to compete effectively and adapt to changing market conditions, our business will be adversely affected.

We compete in markets that are intensely competitive and rapidly changing. Our current and potential competitors vary by size, product offerings and geographic region, and range from start-ups that offer solutions competing with a discrete part of our business to large technology or telecommunications companies that offer, or may be planning to introduce, products and services that are broadly competitive with what we do. The primary competitive factors in our market are differentiation of technology, global presence, quality of solutions, customer service, technical expertise, security, ease-of-use, breadth of services offered, price and financial strength.

Many of our current and potential competitors have substantially greater financial, technical and marketing resources, larger customer bases, broader product portfolios, longer operating histories, greater brand recognition and more established relationships in the industry than we do. As a result, some of these competitors may be able to:

•develop superior products or services;

•leverage better name recognition, particularly in the security and compute markets;

•enter new markets more easily or better manage the impact of changes in general economic conditions, geopolitical conditions and industry pressures;

•gain greater market acceptance for their products and services;

•enter into long-term contracts with our potential customers;

•increase their points of presence and proximity to enterprise data centers and end users faster than us;

•expand their offerings more efficiently and more rapidly;

•bundle their products that are competitive with ours with other solutions they offer in a way that makes our offerings less appealing to, or more costly for, current and potential customers;

•more quickly adapt to new or emerging technologies and changes in customer requirements;

•take advantage of acquisition, investment and other opportunities more readily;

•offer lower prices than ours, including at levels that may not be profitable for us to match;

•spend more money on the promotion, marketing and sales of their products and services;

•spend more money on research and development, including offering higher salaries to talented professionals which may impact our ability to hire or retain engineering and other personnel; and

•implement shorter sales cycles with customers and prospects.

Smaller and more nimble competitors may be able to:

•attract customers by offering less sophisticated versions of products and services than we provide at lower prices than those we charge;

•develop new business models that are disruptive to us;

•in some cases, use funds from public securities offerings or private financings to strengthen their business to enable them to better compete with us; and

•respond more quickly than we can to new or emerging technologies, changes in customer requirements and market and industry developments, resulting in superior offerings.

11

Ultimately, any type of increased competition could result in price and revenue reductions, loss of customers and loss of market share or inability to penetrate new markets, each of which could materially impact our business, profitability, financial condition, results of operations and cash flows.

We and other companies that compete in this industry and these markets experience continually shifting business relationships, reputations, commercial focuses and business priorities, all of which occur in reaction to industry and market forces and the emergence of new opportunities. These shifts have led or could lead to our customers or partners becoming our competitors; network suppliers no longer seeking to work with us; and technology companies that previously did not appear to show interest in the markets we seek to address entering into those markets as our competitors. With this constantly changing environment, we may face operational difficulties in adjusting to the changes or our core strategies could become obsolete. Any of these or other developments could harm our business.

Defects or disruptions in our products and IT systems could require us to increase spending on upgrading systems, diminish demand for our solutions or subject us to substantial liability.

Our solutions are highly complex and are designed to be deployed in and across numerous large and complex networks that we do not control. From time to time, we have needed to correct errors and defects in the proprietary and open-source software that underlies our platform that have given rise to service incidents, outages and disruptions or otherwise impacted our operations. We could face the loss of customers as a result of recent and any future incidents as they seek alternative or supplemental providers. We have also periodically experienced customer dissatisfaction with the quality of some of our delivery, security, compute and other services, which has led to a loss of business and could lead to a loss of customers in the future. Furthermore, most of our customer agreements contain service level commitments. If we fail to meet these contractual commitments, we could be obligated to provide credits for future service, or face contract termination with refunds of prepaid amounts, which could harm our business.

While we have robust quality control processes in place, there may be additional errors and defects in our hardware, software and open-source components that we leverage that may adversely affect our operations. We may not have in place adequate quality assurance procedures to ensure that we detect errors in our hardware, software and open-source components we use in a timely manner, and we may have insufficient resources to efficiently address multiple service incidents happening simultaneously or in rapid succession. We continue to invest in improving our processes and systems. If we are unable to efficiently and cost-effectively fix errors or other problems that we identify and improve the quality of our solutions or systems, or if there are unidentified errors that allow persons to improperly access our services or systems, we could experience litigation, the need to issue credits to customers, loss of revenue and market share, damage to our reputation, diversion of management attention, increased expenses and reduced profitability.

An increasing portion of our revenue is derived from sales of security solutions. Defects in our security solutions could lead to negative publicity, loss of business, damages payments to customers and other negative consequences. As our solutions are adopted by an increasing number of enterprises and governments, it is possible that the adversaries behind advanced malicious actions will specifically focus on finding ways to defeat our products and services. If they are successful, we could experience a serious impact on our reputation as a provider of security solutions.

An increasing portion of our revenue is also derived from the sales of compute solutions. We are devoting significant resources to develop and deploy our own competing cloud-based and SaaS software and services strategies. While we believe our expertise and infrastructure provides us with a strong foundation to compete, it is uncertain whether our strategies will attract the customers or generate the revenue required to be successful. These costs may reduce the gross and operating margins we have previously achieved. Failure to adequately and rapidly deploy additional points of presence, increased proximity to enterprise data centers and end users and develop competitive offerings could result in negative publicity, loss of business, diminishing customer appeal and other negative consequences which could harm our business.

Our business relies on our data systems, traffic measurement systems, billing systems, ordering processes and other operational and financial reporting and control systems. We also rely on third-party software for certain essential operational services and a failure or disruption in these services could materially and adversely affect our ability to manage our business effectively. All of these systems have become increasingly complex due to the complexity of our business, use of third-party software and services, acquisitions of new businesses with different systems, and increased regulation over controls and procedures. As a result, these systems could generate errors that impact traffic measurement or invoicing, revenue recognition and financial forecasting or other parts of our business. We will need to continue to upgrade and improve our data systems, traffic measurement systems, billing systems, ordering processes and other operational and financial systems, procedures and controls. These upgrades and improvements may be difficult and costly. In addition, we could face strains on, or failures of, our internal IT systems if governmental restrictions or vaccine or other mandates due to the emergence of variants in connection

12

with the ongoing COVID-19 pandemic or other emergencies limit the ability of our command center personnel to work in our physical locations. If we are unable to adapt our systems and organization in a timely, efficient and cost-effective manner to accommodate changing circumstances, our business may be adversely affected.

Cybersecurity breaches and attacks on us, as well as steps we need to take in an effort to prevent them, can lead to significant costs and disruptions that would harm our business, financial results and reputation.

We regularly face attempts to gain unauthorized access or deliver malicious software to the Akamai Connected Cloud and our internal IT systems, with the goal of stealing proprietary information related to our business, products, employees and customers; disrupting our systems and services or those of our customers or others; or demanding ransom to return control of such systems and services. These attempts take a variety of forms, including Distributed Denial of Service attacks, infrastructure attacks, botnets, malicious file uploads, application abuse, credential abuse, ransomware, bugs, viruses, worms and malicious software programs. There could be attempts to infiltrate our systems through our supply chain and contractors. Malicious actors are known to attempt to fraudulently induce employees and suppliers to disclose sensitive information through illegal electronic spamming, phishing or other tactics. Other parties may attempt to gain unauthorized physical access to our facilities in order to infiltrate our internal-use information systems. Furthermore, nation state attacks against us or our customers may intensify during periods of heightened geopolitical tensions or armed conflict, such as the ongoing war in Ukraine. While we have taken and continue to take actions to mitigate against attacks by state actors and others, we may not be able to anticipate the techniques used in such attacks, as they change frequently and may not be recognized until launched. To date, cyber threats and other attacks have not resulted in any material adverse impact to our business or operations, but such threats are constantly evolving, increasing the difficulty of detecting and successfully defending against them.

The complexities in managing the security profile of a distributed network with vast scale and geographic reach that evolves to incorporate new capabilities expose us to both known and unknown vulnerabilities. We have discovered vulnerabilities in software used in our technology, such as the vulnerability in Apache Log4j 2 referred to as “Log4Shell” identified in late 2021 that impacted a large portion of the internet ecosystem, and may have other undiscovered vulnerabilities. While the impact to date of Log4Shell on our systems was relatively modest, these vulnerabilities, resident in either software or configurations, may require significant operational efforts to mitigate and may persist for extended periods of time and the effects of any such vulnerability could be exacerbated. Similar security risks exist with respect to acquired companies, our business partners and the third-party vendors that we rely on for aspects of our information technology support services and administrative functions. As a result, we are subject to risks that the activities of our business partners and third-party vendors may adversely affect our business even if an attack or breach does not directly target our systems. See also the risk factor captioned "We utilize third-party technology in our business, and failures or vulnerabilities, and/or litigation, related to these technologies may adversely affect our business" below.

To protect our corporate and deployed networks, we must continuously engineer more secure solutions, enhance security and reliability features, improve the deployment of software updates to address security vulnerabilities, develop mitigation technologies that help to secure customers from attacks and maintain the digital security infrastructure that protects the integrity of our network and services. This is frequently costly, with a negative impact on near-term profitability. We may need to increase our related spending in the future, which could reduce our operating margin.

Any actual, alleged or perceived breach of network security in our systems or networks, or any other actual, alleged or perceived data security incident we, our customers or our third-party suppliers suffer, can result in damage to our reputation; negative publicity; loss of channel partners, customers and sales; loss of competitive advantages; increased costs to remedy any problems and otherwise respond to any incident; regulatory investigations and enforcement actions; costly litigation; and other liabilities. With the recent acquisition of Linode, we are adapting procedures for mitigating harms that may arise from abuse of our compute products. If we fail to mitigate these or if there is a significant cybersecurity event using our compute products or our compute products are perceived to be less reliable than our competitors, it could result in loss of customers and reputational damage. In addition, we may incur significant costs and operational consequences of investigating, remediating, eliminating and putting in place additional tools and devices designed to prevent actual or perceived security breaches and other security incidents, as well as the costs to comply with any notification obligations resulting from any security incidents. Any of these negative outcomes could adversely impact the market perception of our solutions and customer and investor confidence in our company and otherwise seriously harm our business and operating results.

13

If we cannot maintain compatibility with our customers’ IT infrastructure, including their chosen third-party applications, our business will be harmed.

Our products interoperate with our customers' IT infrastructure that often has different specifications, utilizes diverse technology, and requires compatibility with multiple communication protocols. Therefore, the functionality of our technology often needs to have, and maintain, compatibility with our customers' technology environment, including their chosen third-party technology. Customers, and in particular these chosen third-party applications, may change features, restrict our access to, or alter their applications in a manner that causes incompatibilities or causes us significant costs to maintain compatibility, and as a result our business could be adversely affected. Such changes could functionally limit or prevent the compatibility of our products with our customers’ IT infrastructure, which would negatively affect adoption of our products and harm our business. If we fail to update our products to achieve compatibility with new third-party applications that our customers use, we may not be able to offer the functionality that our customers need, which would harm our business.

We face risks associated with global operations that could harm our business.

A significant portion of our employee increases, customer additions and revenue growth in recent quarters has been attributable to our business outside the U.S. Our operations in foreign countries subject us to risks that may increase our costs, impact our financial results, disrupt our operations or make our operations less efficient and require significant management attention. These risks include:

•foreign exchange rate risks, including the recent strengthening of the U.S. dollar which has led to a decrease in our revenue from certain customers and corresponding pressure on our earnings;

•uncertainty regarding liability for content or services, including uncertainty as a result of local laws and lack of legal precedent;

•loss of revenues if the U.S. or foreign governments impose limitations on doing business with significant current or potential customers;

•adjusting to different employee/employer relationships and different regulations governing such relationships;

•becoming subject to regulatory oversight;

•corporate and personal liability for alleged or actual violations of laws and regulations;

•difficulty in staffing, training, developing and managing foreign operations as a result of distance, language, cultural differences or regulations;

•theft of intellectual property in high-risk countries where we operate;

•difficulties in enforcing contracts, collecting accounts and longer payment cycles in certain countries;

•difficulties in transferring funds from, or converting currencies in, certain countries;

•managing the costs and processes necessary to comply with export control, sanctions, such as the sanctions imposed in connection with the Russian invasion of Ukraine, anti-corruption, data protection and competition laws and regulations or other regulatory or contractual limitations on our ability to sell or develop our products and services in certain foreign markets;

•macroeconomic developments and changes in the labor markets in which we operate;

•geopolitical developments, including any that impact our or our customers’ ability to operate or deliver content to a country;

•other circumstances outside of our control such as trade disputes, political unrest, the imposition of sanctions, export controls, warfare, military or armed conflict, such as the Russian invasion of Ukraine, terrorist attacks, public health emergencies such as the ongoing COVID-19 pandemic, energy crises and natural disasters that could disrupt our ability to provide services or limit customer purchases of them;

•reliance on one or more channel partners over which we have limited control or influence on a day-to-day basis; and

•potentially adverse tax consequences.

We are subject to laws and regulations worldwide that differ among jurisdictions, affecting our operations in areas such as intellectual property ownership and infringement; tax; anti-corruption; internet and technology regulations; so-called "fair share" or internet content taxes; foreign exchange controls and cash repatriation; data privacy; cyber security; competition; consumer protection; and employment. Compliance with such requirements can be onerous and expensive and may otherwise impact our business operations negatively. Although we have policies, controls and procedures designed to help ensure compliance with applicable laws, there can be no assurance that our employees, contractors, suppliers or agents will not violate such laws or our policies. Violations of these laws and regulations can result in fines; criminal sanctions against us, our officers or our employees; prohibitions on the conduct of our business; and damage to our reputation. See also the risk factor captioned Other regulatory developments could negatively impact our business below.

14

Our business strategy depends on the ability to source adequate transmission capacity, co-location facilities and the equipment we need to operate our network; failure to have access to those resources could lead to loss of revenue and service disruptions.

To operate and grow our network, we are dependent in part upon transmission capacity provided by third-party telecommunications network providers, the availability of co-location facilities to house our servers and equipment to support our operations. We may be unable to purchase the bandwidth and space we need from these providers due to limitations on their resources, increasing energy costs or other reasons outside of our control. In particular, following our acquisition of Linode, our plans to increase the size and scale of our cloud computing offerings will require procuring significant additional space in co-location facilities. Inability to access facilities where we would like to install servers, or perform maintenance on existing servers for any reason, such as the imposition of stay-at-home orders imposed in connection with the ongoing COVID-19 pandemic or other emergencies, impedes our ability to expand or maintain capacity. As a result, there can be no assurance that we are adequately prepared for unexpected increases in capacity demands by our customers, particularly those under cyber-attack or impacted by geopolitical conditions. Failure to put in place the capacity we require to operate our business effectively could result in a reduction in, or disruption of, service to our customers and ultimately a loss of those customers.

The Akamai Connected Cloud relies on hardware equipment, including hundreds of thousands of servers deployed around the world. Global supply chain constraints in the wake of the COVID-19 pandemic continue to increase lead times for equipment components, which adds risk to our ability to flex to meet future business needs and expand our global compute presence. Disruptions in our supply chain could prevent us from purchasing needed equipment at attractive prices or at all. For example, from time to time, it has been, and may continue to be, more difficult to purchase equipment that is manufactured in areas that face disruptions to operations due to unrest, trade sanctions or other political activity, public health issues (such as the ongoing COVID-19 pandemic), safety issues, natural disasters or general economic conditions. Failure to have adequate equipment, including server equipment, could harm the quality of our services, which could lead to the loss of customers and revenue.

Acquisitions and other strategic transactions we complete could result in operating difficulties, dilution, diversion of management attention and other harmful consequences that may adversely impact our business and results of operations.

We expect to continue to pursue acquisitions and other types of strategic relationships that involve technology sharing or close cooperation with other companies. Acquisitions and other complex transactions are accompanied by a number of risks, including the following:

•difficulty integrating the technologies, operations and personnel of acquired businesses;

•potential disruptions of our ongoing business;

•potential distraction of management;

•diversion of business resources from core operations;

•financial consequences, such as increased operating expenses, incurrence of material post-closing liabilities, incurrence of additional debt and other dilutive effects on our earnings, particularly in the current environment where we have generally seen escalating valuations of many technology companies and increasing allocation of risk to acquirors;

•assumption of legal risks related to compliance with laws, including privacy and anti-corruption regulations;

•failure to realize synergies or other expected benefits;

•lawsuits resulting from an acquisition or disposition;

•retention of the acquired company's key talent;

•there may be unexpected regulatory changes resulting in operating difficulties and expenditures;

•acquisition of IT systems that expose us to cybersecurity risks and additional costs to remedy such risks;

•increased accounting charges such as impairment of goodwill or intangible assets, amortization of intangible assets acquired and a reduction in the useful lives of intangible assets acquired; and

•potential unknown liabilities associated with acquired businesses.

Any inability to integrate completed acquisitions or combinations in an efficient and timely manner could have an adverse impact on our results of operations. If we use a significant portion of our available cash to pay for acquisitions that are not successful, it could harm our balance sheet and limit our flexibility to pursue other opportunities without having enjoyed the intended benefits of the acquisition. As we complete any future acquisitions, we may encounter difficulty in incorporating acquired technologies into our offerings while maintaining the quality standards that are consistent with our brand and reputation. If we are not successful in completing acquisitions or other strategic transactions that we may pursue in the future, we may incur substantial expenses and devote significant management time and resources without a successful result. Future acquisitions could require use of substantial portions of our available cash or result in dilutive issuances of securities.

15

If current and potential large customers shift to hardware-based or other DIY internal solutions, our business will be negatively impacted.

We are reliant on large media and other customers to direct traffic to our network for a significant part of our revenues. In the past, some of those customers have determined that it is better for them to employ a “do-it-yourself” or “DIY” strategy by putting in place equipment, software and other technology solutions for content and application delivery and security protection within their internal systems instead of using our solutions for some or all of their needs. Essentially, this is another form of competition for us. As the amount of money a customer spends with us increases, the risk that they will seek alternative solutions such as DIY or a multi-vendor policy likewise increases. If additional large customers shift to this model, traffic on our network and our contracted revenue commitments would decrease, which would negatively impact our business, profitability, financial condition, results of operations and cash flows.

If we are unable to recruit and retain key employees and qualified sales, research and development, technical, marketing and support personnel, our ability to compete could be harmed.

Our future success depends upon the services of our executive officers and other key technology, sales, research and development, marketing and support personnel who have critical industry experience and relationships. Like other companies in our industry, we have experienced, and we expect to continue to experience, difficulty in hiring and retaining highly skilled employees with appropriate qualifications, and, if we fail to attract new personnel or fail to retain and motivate our current personnel or effectively train our current employees to support our business needs, our business and future growth prospects could suffer. For example, none of our officers or key employees is bound by an employment agreement for any specific term, and members of our senior management have left our company over the years for a variety of reasons. In addition, effective succession planning is important to our long-term success and our failure to ensure effective transfer of knowledge and smooth transitions involving our officers and other key personnel could hinder our strategic planning and execution.

In addition, our future success will depend upon our ability to attract, train and retain employees, particularly in our expected areas of growth such as security and cloud computing. Such efforts will require time, expense and attention by our employees as there is significant competition for talented individuals in the regions in which our primary offices are located, which affects both our ability to retain key employees and hire new ones and new hires require significant training. This competition results in increased costs in the form of cash and stock-based compensation and can have a dilutive impact on our stock. In addition, we are retasking certain of our employees to work on our compute solutions which will require the use of our resources and if we are unable to successfully retrain our employees, our compute business may suffer. The loss of the services of a significant number of our employees or any of our key employees or our inability to attract and retain new talent in a timely fashion may be disruptive to our operations and overall business.

Our failure to effectively manage our operations and maintain our company culture as our business evolves and our work practices change could harm us.

Our future operating results will depend on our ability to manage our operations and we believe our culture has been a key contributor to our success to date. As a result of the diversification of our business, personnel growth, increased usage of alternative working arrangements, including the designation of over 95% of roles as flexible and able to work remotely, acquisitions and international expansion in recent years, many of our employees are now based outside of our Cambridge, Massachusetts headquarters; however, most key management decisions are made by a relatively small group of individuals based primarily at our headquarters.

If we are unable to appropriately increase management depth, enhance succession planning and decentralize our decision-making at a pace commensurate with our actual or desired growth rates, we may not be able to achieve our financial or operational goals. It is also important to our continued success that we hire qualified personnel, properly train them and manage out poorly-performing personnel, all while maintaining our corporate culture and spirit of innovation. If we are not successful in these efforts, our growth and operations could be adversely affected.

We rolled out our FlexBase program in May 2022, which allows the more than 95% of our workforce designated as flexible to choose whether they want to work from an Akamai office, their home office or a combination of both. Although we believe a flexible working policy will help us attract and retain talent, our FlexBase program could, among other things, negatively impact employee morale and productivity, inhibit our ability to hire and train new employees and impede our ability to support customers at the levels they expect. In addition, certain security systems in homes or other remote workplaces may be less secure than those used in our offices, which may subject us to increased security risks, including cybersecurity-related

16

events, and expose us to risks of data or financial loss and associated disruptions to our business operations. Members of our workforce who access company data and systems remotely may not have access to technology that is as robust as that in our offices, which could cause the networks, information systems, applications and other tools available to those remote workers to be more limited or less reliable than in our offices. We may also be exposed to risks associated with the locations of remote workers, including compliance with local laws and regulations or exposure to compromised internet infrastructure. Allowing members of our workforce to work remotely may create intellectual property risk if employees create intellectual property on our behalf while residing in a jurisdiction with unenforced or uncertain intellectual property laws. Further, if employees fail to inform us of changes in their work location, we may be exposed to additional risks without our knowledge. If we are unable to effectively transition to a hybrid workforce, manage the cybersecurity and other risks of remote work, and maintain our corporate culture and workforce morale, our business could be harmed or otherwise negatively impacted.

Our restructuring and reorganization activities may be disruptive to our operations and harm our business.

Over the past several years, we have implemented internal restructurings and reorganizations designed to reduce the size and cost of our operations, improve operational efficiencies, enhance our ability to pursue market opportunities and accelerate our technology development initiatives. In February 2021, we announced a significant reorganization to create two new business groups linked to our security and edge delivery technologies as well as establishing a unified global sales force. We may take similar steps in the future as we seek to realize operating synergies, optimize our operations to achieve our target operating model and profitability objectives, respond to market forces or better reflect changes in the strategic direction of our business. Disruptions in operations may occur as a result of taking these actions. Taking these actions may also result in significant expense for us, including with respect to workforce reductions, as well as decreased productivity due to employee distraction and unanticipated employee turnover. Substantial expense or business disruptions resulting from restructuring and reorganization activities could adversely affect our operating results.

We may have exposure to greater-than-anticipated tax liabilities.

Our future income taxes could be adversely affected by earnings being lower than anticipated in jurisdictions that have lower statutory tax rates and higher than anticipated in jurisdictions that have higher statutory tax rates, or changes in tax laws, regulations or accounting principles, as well as certain discrete items such as equity-related compensation. In particular, in October 2021, a global consortium of countries agreed to establish a new framework for international tax reform, including the general rules for redefined jurisdictional taxation rights and a global minimum tax of 15% (Pillar 2). In December 2022, the European Union member states voted unanimously to adopt a Directive implementing the Pillar 2 (global minimum tax) rules giving member states until December 31, 2023 to implement the Directive into national legislation. Further details regarding implementation of these rules are expected and if implemented, such reform may increase our tax liabilities and compliance costs and reduce our profitability. We have recorded certain tax reserves to address potential exposures involving our income tax and sales and use tax positions. These potential tax liabilities result from the varying application of statutes, rules, regulations and interpretations by different jurisdictions. We are currently subject to tax audits in various jurisdictions. If the ultimate outcome of any tax audits are adverse to us, our reserves may not be adequate to cover our total actual liability, and we would need to take a financial charge. Although we believe our estimates, our reserves and the positions we have taken in all jurisdictions are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.

On August 16, 2022, President Joseph R. Biden signed into law the Inflation Reduction Act of 2022 (“IRA”). The IRA includes a 15% corporate alternative minimum tax for companies with modified GAAP net income in excess of $1 billion, a 1% excise tax on certain stock repurchases, and numerous environmental and green energy tax credits. Currently, we are not subject to the corporate alternative minimum tax. We are currently evaluating the impacts of the excise tax on our stock repurchase program; however, we do not currently expect the new law to have a material impact on our results of operations.

Fluctuations in foreign currency exchange rates affect our reported operating results in U.S. dollar terms.

Revenue generated and expenses incurred by our international subsidiaries are often denominated in the currencies of the local countries. As a result, our consolidated U.S. dollar financial statements are subject to fluctuations due to changes in exchange rates as the financial results of our international subsidiaries are translated from local currencies into U.S. dollars. In addition, our financial results are subject to changes in exchange rates that impact the settlement of transactions in non-functional currencies. While we have implemented a foreign currency hedging program to mitigate transactional exposures, there is no guarantee that such program will be effective.

17

If the accounting estimates we make, and the assumptions on which we rely, in preparing our financial statements prove inaccurate, our actual reported results may be adversely affected.

Our financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments about, among other things, taxes, revenue recognition, stock-based compensation, capitalization of internal-use software development costs, investments, contingent obligations, allowance for current expected credit losses, intangible assets and restructuring charges. These estimates and judgments affect, among other things, the reported amounts of our assets, liabilities, revenue and expenses, the amounts of charges accrued by us, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances and at the time they are made. If our estimates or the assumptions underlying them are not correct, actual results may differ materially from our estimates and we may need to, among other things, accrue significant additional charges that could adversely affect our results of operations, which in turn could adversely affect our stock price. Errors in our financial statements have occurred in the past and may occur in the future. For example, see Note 23 for a description of an error identified in January 2023. In addition, new accounting pronouncements and interpretations of accounting pronouncements have occurred and may occur in the future that could adversely affect our reported financial results.

Our sales to government clients subject us to risks, including early termination, audits, investigations, sanctions and penalties.

We have customer contracts with the U.S. government, as well as foreign, state and local governments and their respective agencies and we may in the future increase sales to government entities. Sales to government entities are subject to a number of risks. Selling to government entities can be highly competitive, expensive, and time consuming, often requiring significant upfront time and expense without any assurance that these efforts will generate a sale. Such government entities often have the right to terminate these contracts at any time, without cause. There is increased pressure for governments and their agencies, both domestically and internationally, to reduce spending and demand and payment for our services may be impacted by public sector budgetary cycles and funding authorizations. These factors may combine to potentially limit the revenue we derive from government contracts in the future. Additionally, government contracts generally have requirements that are more complex than those found in commercial enterprise agreements and therefore are more costly to comply with. Such contracts are also subject to audits and investigations that could result in civil and criminal penalties and administrative sanctions, including termination of contracts, refund of a portion of fees received, forfeiture of profits, suspension of payments, fines and suspensions or debarment from future government business.

We utilize third-party technology in our business, and failures or vulnerabilities, and/or litigation, related to these technologies may adversely affect our business.

We utilize third-party technology software, services, and other technology in order to operate critical functions of our business, including the integration of certain of these technologies into our network, products and services. If these software, services, or other technology become unavailable or contain vulnerabilities, our expenses could increase and our ability to operate our network, provide our products, and our results of operations could be impaired until equivalent software, technology, or services are purchased or developed or any identified vulnerabilities are remedied. If we are unable to procure the necessary third-party technology we may need to acquire or develop alternative technology, or we may have to resort to utilizing alternative technology of lower quality. This could limit and delay our ability to offer new or competitive products and increase our costs of production. As a result, our business could be significantly harmed. In addition, the use of third-party technology may expose us to third-party claims of intellectual property infringement which could cause us to incur significant costs in defense or alternative sourcing.

We rely on certain “open-source” software, which may contain security flaws or other deficiencies, and the use of which could result in our having to distribute our proprietary software, including source code, to third parties on unfavorable terms, either of which could materially affect our business.

Certain of our offerings use software that is subject to open-source licenses. Open-source code is software that is freely accessible, usable and modifiable; however, certain open-source code is governed by license agreements, the terms of which could require users of such software to make any derivative works of the software available to others on unfavorable terms or at no cost. Because we use open-source code, we may be required to take remedial action in order to protect our proprietary software. Such action could include replacing certain source code used in our software, discontinuing certain of our products or taking other actions that could be expensive and divert resources away from our development efforts. In addition, the terms relating to disclosure of derivative works in many open-source licenses are unclear and have not been interpreted by U.S.

18

courts. If a court interprets one or more such open-source licenses in a manner that is unfavorable to us, we could be required to make certain of our key software generally available at no cost. We could also be subject to similar conditions or restrictions should there be any changes in the licensing terms of the open-source software incorporated into our products. In either event, we could be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished on a timely or successful basis, any of which could adversely affect our business, operating results and financial condition. Furthermore, open-source software may have security flaws and other deficiencies that could make our solutions less reliable and damage our business.

Legal and Regulatory Risks

Evolving privacy regulations could negatively impact our profitability and business operations.

Laws and regulations that apply to the internet related to privacy and international data transfer restrictions could pose risks to our revenues, intellectual property and customer relationships, as well as increase expenses or create other disadvantages to our business.

Privacy laws are rapidly proliferating, changing and evolving globally. Governments, private citizens and privacy advocates with class action attorneys are increasingly scrutinizing how companies collect, process, use, store, share and transmit personal data. Numerous laws, such as the European Union's General Data Protection Regulation ("GDPR"), and the California Consumer Privacy Act of 2018 ("CCPA"), and industry self-regulatory codes have been enacted, and more laws are being considered that may affect how we use data generated from our network as well as our ability to reach current and prospective customers, understand how our solutions are being used and respond to customer requests allowed under the laws. Any perception that our business practices, our data collection activities or how our solutions operate represent an invasion of privacy or improper practice, whether or not consistent with current regulations and industry practices, may subject us to public criticism or boycotts, class action lawsuits, reputational harm, or actions by regulators, or claims by industry groups or other third parties, all of which could disrupt our business and expose us to liability.

Engineering efforts to build new capabilities to facilitate compliance with increasing international data transfer restrictions and new and changing privacy laws and related customer demands could require us to take on substantial expense and divert engineering resources from other projects. We might experience reduced demand for our offerings if we are unable to engineer products that meet our legal duties or help our customers meet their obligations under the GDPR, the CCPA or other data regulations, or if the changes we implement to comply with such laws and regulations make our offerings less attractive.

Our ability to leverage the data generated by our global networks is important to the value of many of the solutions we offer, our operational efficiency and future product development opportunities. Our ability to use data in this way may be constrained by regulatory developments. Compliance with applicable laws and regulations regarding personal data may require changes in services, business practices or internal systems that result in increased costs, lower revenue, reduced efficiency or greater difficulty in competing with other firms. Compliance with data regulations might limit our ability to innovate or offer certain features and functionality in some jurisdictions where we operate. Failure to comply with existing or new rules may result in significant penalties or orders to stop the alleged non-compliant activity, as well as negative publicity and diversion of management time and effort.

Although we take steps intended to improve the security controls across our business groups and geographies, our security controls over personal data, our training of employees and third parties on privacy, data security and other practices we follow may not prevent the improper disclosure or misuse of customer or end-user data we process. Improper disclosure or misuse of personal data could harm our reputation, lead to legal exposure to customers or end users, or subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue.

Other regulatory developments could negatively impact our business.

Local and foreign laws and regulations that apply to the internet related to, among other things, content liability, security requirements, law enforcement access to information, critical infrastructure, so-called "fair share" or internet content taxes, international data transfer restrictions, sanctions, export controls and restrictions on social media or other content could pose risks to our revenues, intellectual property and customer relationships as well as increase expenses or create other disadvantages to our business. Section 230 of the U.S. Communications Decency Act, often referred to as Section 230, gives websites that host user-generated content broad protection from legal liability for content posted on their sites. Proposals to repeal or amend Section 230 could expose us to greater legal liability in the conduct of our business. Our Acceptable Use Policy prohibits customers from using our network to deliver illegal or inappropriate content; if customers violate that policy, we may nonetheless face reputational damage, enforcement actions or lawsuits related to their content. Regulations have been enacted

19

or proposed in a number of countries that limit the delivery of certain types of content into those countries. Enactment and expansion of such laws and regulations would negatively impact our revenues. For example, restrictions were adopted in India in 2020 prohibiting access to identified Chinese applications which caused a reduction in revenue to us. In addition, such laws and regulations could cause internet service providers, or others, to block our products in order to enforce content-blocking efforts. In addition, efforts to block a single product or domain name may end up blocking a number of other products or domain names in an overbroad manner that could affect our business. Interpretations of laws or regulations that would subject us to regulatory enforcement actions, supervision or, in the alternative, require us to exit a line of business or a country, could lead to loss of significant revenues and have a negative impact on the quality of our solutions. As noted with privacy compliance above, engineering efforts to build new capabilities to facilitate compliance with law enforcement access requirements, content access restrictions or other regulations could require us to take on substantial expense and divert engineering resources from other projects. These circumstances could harm our profitability.

We may need to defend against patent or copyright infringement claims, which would cause us to incur substantial costs or limit our ability to use certain technologies in the future.

As we expand our business and develop new technologies, products and services, we have become increasingly subject to intellectual property infringement and other claims and related litigation. We have also agreed to indemnify our customers and channel and strategic partners if our solutions infringe or misappropriate specified intellectual property rights; as a result, we have been and could again become involved in litigation or claims brought against customers or channel or strategic partners if our solutions or technology are the subject of such allegations. Any litigation or claims, whether or not valid, brought against us or pursuant to which we indemnify our customers or partners could result in substantial costs and diversion of resources and require us to do one or more of the following:

•cease selling, incorporating or using features, functionalities, products or services that incorporate the challenged intellectual property;

•pay substantial damages and incur significant litigation expenses;

•obtain a license from the holder of the infringed intellectual property right, which license may not be available on reasonable terms or at all; or

•redesign products or services.

If we are forced to take any of these actions, our business may be seriously harmed.

Our business will be adversely affected if we are unable to protect our intellectual property rights from unauthorized use or infringement by third parties.

We rely on a combination of patent, copyright, trademark and trade secret laws and contractual restrictions on disclosure to protect our intellectual property rights. These legal protections afford only limited protection, particularly in some regions outside the U.S. We have previously brought lawsuits against entities that we believed were infringing our intellectual property rights but have not always prevailed. Such lawsuits can be expensive and require a significant amount of attention from our management and technical personnel, and the outcomes are unpredictable. Monitoring unauthorized use of our solutions is difficult, and we cannot be certain that the steps we have taken or will take will prevent unauthorized use of our technology. Furthermore, we cannot be certain that any pending or future patent applications will be granted, that any future patent will not be challenged, invalidated or circumvented, or that rights granted under any patent that may be issued will provide competitive advantages to us. If we are unable to protect our proprietary rights from unauthorized use, the value of our intellectual property assets may be reduced. Although we have licensed from other parties proprietary technology covered by patents, we cannot be certain that any such patents will not be challenged, invalidated or circumvented. Such licenses may also be non-exclusive, meaning our competition may also be able to access such technology.

Litigation may adversely impact our business.

From time to time, we are or may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including patent, commercial, product liability, breach of contract, employment, class action, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings. In addition, under our charter, we could be required to indemnify and advance expenses to our directors and officers in connection with their involvement in certain actions, suits, investigations and other proceedings. Such matters can be time-consuming, divert management’s attention and resources and cause us to incur significant expenses. Furthermore, because litigation is inherently unpredictable and may not be covered by insurance, there can be no assurance that the results of any litigation matters will not have an adverse impact on our business, results of operations, financial condition or cash flows.

20

In addition, from time to time, we use various contractual, technical and expert resources to reduce the likelihood of end user activity that is illegal, fraudulent or harmful to third parties. There can be no assurance that any of these initiatives will be successful or reduce such illegal, fraudulent or harmful content on our platform. Furthermore, such initiatives may also result in negative interactions with end users, negative perceptions of our policies or increased onboarding time for new customers.

Global climate change and related natural resource conservation regulations could adversely impact our business.

The long-term effects of climate change on the global economy and our industry in particular remain unknown. For example, changes in weather where we operate may increase the costs of powering and cooling computer hardware we use to develop software and provide cloud-based services. In addition, catastrophic natural disasters, such as an earthquake, fire, flood or other act of God, catastrophic event or pandemic, and any similar disruption, as well as any derivative disruption, such as those to services provided through localized physical infrastructure, including utility or telecommunication outages, or any to the continuity of our, our partners’, suppliers’ and our customers’ workforce, could have a material adverse impact on our business and operating results. Our global operations are dependent on our network infrastructure, technology systems and website, including the supply of servers from our third-party partners, as well as our intellectual property and personnel and any disruption to these dependencies may negatively impact our ability to respond to customers, provide services and maintain local and global business continuity. Furthermore, some of our products and business functions are hosted or carried out by third parties that may be vulnerable to these same types of disruptions, the response to or resolution of which may be beyond our control. Any disruption to our business could cause us to incur significant costs to repair damages to our facilities, equipment, infrastructure and business relationships.

In addition, in response to concerns about global climate change, governments may adopt new regulations affecting the use of fossil fuels or requiring the use of alternative fuel sources which could adversely impact our business. Our deployed network of servers consumes significant energy resources, including those generated by the burning of fossil fuels. While we have invested in projects to support renewable energy development, our customers, investors and other stakeholders may require us to take more steps to demonstrate that we are taking ecologically responsible measures in operating our business. The costs and any expenses we may incur to make our network more energy-efficient and comply with any new regulations could make us less profitable in future periods. Failure to comply with applicable laws and regulations or other requirements imposed on us could lead to fines, lost revenue and damage to our reputation.

Investment-Related Risks

Our stock price has been, and may continue to be, volatile, and your investment could lose value.

The market price of our common stock has historically been volatile. Trading prices may continue to fluctuate in response to a number of events and factors, including the following:

•quarterly variations in operating results;

•announcements by our customers related to their businesses that could be viewed as impacting their usage of our solutions;

•market speculation about whether we are a takeover target or considering a strategic transaction;

•announcements by competitors;

•activism by any single large stockholder or combination of stockholders or rumors about such activity;

•changes in financial estimates and recommendations by securities analysts;

•failure to meet the expectations of securities analysts;

•purchases or sales of our stock by our officers and directors;

•general economic conditions and other macroeconomic factors, such as inflationary pressures, foreign currency exchange rate fluctuations, energy prices, reduced consumer spending, increasing interest rates, recessionary economic cycles, protracted economic slowdowns and overall market volatility;

•repurchases of shares of our common stock;

•successful cyber-attacks affecting our network or systems;

•changes in the composition of company management, including company executives and the board of directors;

•entry into, or termination of, relationships with material customers and partners;

•performance by other companies in our industry; and

•geopolitical conditions such as acts of terrorism, military or armed conflicts, such as the Russian invasion of Ukraine, or global pandemics.

Furthermore, our revenue, particularly that portion attributable to usage of our solutions beyond customer commitments, can be difficult to forecast, and, as a result, our quarterly operating results can fluctuate substantially. This concern is particularly acute with respect to our media and commerce customers. In the future, our customer contracting models may

21

change to move away from a committed revenue structure to a “pay-as-you-go” approach, which could make it easier for customers to reduce the amount of business they do with us or leave altogether. Changes in billing models and committed revenue requirements could, therefore, create challenges with our forecasting processes. Because a significant portion of our cost structure is largely fixed in the short-term, revenue shortfalls tend to have a disproportionately negative impact on our profitability. If we announce revenue or profitability results that do not meet or exceed our guidance or make changes in our guidance with respect to future operating results, our stock price may decrease significantly as a result.

Any of these events, as well as other circumstances discussed in these Risk Factors, may cause the price of our common stock to fall. In addition, the stock market in general, and the market prices of stock of publicly-traded technology companies in particular, have experienced significant volatility that often has been unrelated to the operating performance of affected companies. These broad stock market fluctuations may adversely affect the market price of our common stock, regardless of our operating performance.

Any failure to meet our debt obligations or obtain financing would damage our business.

As of the date of this report, we had total principal amount of $1,150.0 million of convertible senior notes outstanding due in 2025, and we had total principal amount of $1,150.0 million of convertible senior notes outstanding due in 2027. We also entered into a credit facility in November 2022 that provides for an initial $500.0 million revolving credit facility, and under specified circumstances, the credit facility can be increased to up to $1 billion in aggregate principal amount. As of December 31, 2022, there were no outstanding borrowings under the credit facility. Our ability to repay any amounts we borrow under our credit facility, refinance the notes, make cash payments in connection with conversions of the notes or repurchase the notes in the event of a fundamental change (as defined in the applicable indenture governing the notes) will depend on market conditions and our future performance, which is subject to economic, financial, competitive and other factors beyond our control. We also may not use the cash we have raised through future borrowing under the credit facility or the issuance of the convertible senior notes in an optimally productive and profitable manner. If we are unable to remain profitable or if we use more cash than we generate in the future, our level of indebtedness at such time could adversely affect our operations by increasing our vulnerability to adverse changes in general economic and industry conditions and by limiting or prohibiting our ability to obtain additional financing for additional capital expenditures, acquisitions and general corporate and other purposes. If we do not have sufficient cash upon conversion of the notes or to repurchase the notes following a fundamental change, we would be in default under the terms of the notes, which could seriously harm our business. Although the terms of our credit facility include certain financial ratios that potentially limit our future indebtedness, the terms of the notes do not. If we incur significantly more debt, this could intensify the risks described above. In addition, if we are unable to obtain financing to fund additional capital expenditures, acquisitions, and general corporate and other purposes on reasonable terms, or at all, then our business, operations and financial condition may be harmed.

We may issue additional shares of our common stock or instruments convertible into shares of our common stock and thereby materially and adversely affect the market price of our common stock.

Our board of directors has the authority to issue additional shares of our common stock or other instruments convertible into, or exchangeable or exercisable for, shares of our common stock. If we issue additional shares of our common stock or instruments convertible into, or exchangeable or exercisable for, shares of our common stock, it may materially and adversely affect the market price of our common stock.

Because we currently do not intend to pay dividends, stockholders will benefit from an investment in our common stock only if it appreciates in value.

We currently intend to retain our future earnings, if any, for use in the operation of our business and do not expect to pay any cash dividends in the foreseeable future on our common stock. As a result, the success of an investment in our common stock will depend upon any future appreciation in its value. There is no guarantee that our common stock will appreciate in value or even maintain the price at which stockholders have purchased their shares.

Provisions of our charter, by-laws and Delaware law may have anti-takeover effects that could prevent a change in control even if the change in control would be beneficial to our stockholders.

Provisions of our charter, by-laws and Delaware law could make it more difficult for a third party to control or acquire us, even if doing so would be beneficial to our stockholders. These provisions include:

•our board of directors having the right to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director;

22

•stockholders needing to provide advance notice, additional disclosures and representations and warranties to nominate individuals for election to the board of directors or to propose matters that can be acted upon at a stockholders' meeting; and

•the ability of our board of directors to issue, without stockholder approval, shares of undesignated preferred stock.

Further, as a Delaware corporation, we are also subject to certain Delaware anti-takeover provisions. Under Delaware law, a corporation may not engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other things, the board of directors has approved the transaction. Our board of directors could rely on Delaware law to prevent or delay an acquisition of us.

We have identified a material weakness in our internal control over financial reporting, and our management has concluded that our disclosure controls and procedures are not effective. While we are working to remediate the identified material weakness, we cannot assure you that additional material weaknesses or significant deficiencies will not occur in the future. If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. As a result, our stockholders could lose confidence in our financial reporting, which could harm our business and the trading price of our common stock.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. As disclosed in this Form 10-K, in the course of our audit for fiscal 2022, we identified a material weakness in the Company’s internal control over financial reporting as of December 31, 2022 related to income taxes. The material weakness was caused by an inadequate control over the adoption and application of new accounting standards related to income taxes and resulted in immaterial errors to net deferred tax assets and provision for income taxes for the interim periods ended March 31, 2022, June 30, 2022 and September 30, 2022. We are in the process of designing and implementing changes in processes and controls to remediate the material weakness. We cannot assure you that the measures we may take in the future will be sufficient to remediate the control deficiencies that led to a material weakness in our internal controls over financial reporting or that they will prevent or avoid potential future material weaknesses. The material weakness in the Company’s internal control over financial reporting will not be considered remediated until the controls operate for a sufficient period of time and management has concluded, through testing that these controls operate effectively. If we do not successfully remediate the material weakness, or if other material weaknesses or other deficiencies arise in the future, we may be unable to accurately report our financial results, which could cause our financial results to be materially misstated and require restatement.

We need to continue to enhance and maintain our processes and systems and adapt them to changes as our business evolves and we rearrange management responsibilities and reorganize our business. This continuous process of maintaining and adapting our internal controls and complying with Section 404 is expensive and time-consuming and requires significant management attention. We cannot be certain that our internal control measures will provide in the future adequate control over our financial processes and reporting and ensure compliance with Section 404. Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm our operating results, may result in a restatement of our financial statements for prior periods, cause us to fail to meet our reporting obligations, and could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we are required to include in the periodic reports we will file with the Securities and Exchange Commission. Furthermore, as our business changes, including by expanding our operations in different markets, increasing reliance on channel partners and completing acquisitions, our internal controls may become more complex and we may be required to expend significantly more resources to ensure our internal controls remain effective. Failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. If we or our independent registered public accounting firm identify additional material weaknesses, the disclosure of that fact, even if quickly remediated, could reduce the market's confidence in our financial statements and harm our stock price.

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

This Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A"), should be read in conjunction with our consolidated financial statements and notes thereto that appear elsewhere in this annual report on Form 10-K. See “Risk Factors” elsewhere in this annual report on Form 10-K for a discussion of certain risks associated with our business. The following discussion contains forward-looking statements. The forward-looking statements do not include the potential impact of any mergers, acquisitions, divestitures or other events that may be announced after the date hereof.

Overview

We provide solutions to power and protect life online. The key factors that influence our financial success are our ability to build on recurring revenue commitments for our security and performance offerings, increase traffic on our network, continue to develop, scale and successfully bring to market our cloud computing platform and compute-to-edge solutions that meet the needs of professional users and enterprises, effectively manage the prices we charge for our solutions, develop new products and appropriately manage our capital spending and other expenses. The purpose of this discussion and analysis section is to provide material information relevant to an assessment of our financial condition and results of operations from management’s perspective, including to describe and explain key trends, events and other factors that impacted our reported results and that are likely to impact our future performance.

Revenue

For most of our solutions, our customers commit to contracts having terms of a year or longer, which allows us to have a consistent and predictable base level of revenue. In addition to a base level of revenue, we are also dependent on delivery customers, and some cloud computing customers, where usage of our solutions is more variable. As a result, our revenue is impacted by the amount of traffic we serve on our network or the usage of cloud computing services, the rate of adoption of gaming, social media and video platform offerings, the timing and variability of customer-specific one-time events and geopolitical, economic and other developments that impact our customers' businesses. Seasonal variations that impact traffic on our network, such as holiday-related activities, can cause revenue fluctuations from quarter to quarter. Over the longer term, our ability to expand our product portfolio and to effectively manage the prices we charge for our solutions are key factors impacting our revenue growth.

We have observed the following trends related to our revenue in recent years:

•Increased sales of our security solutions, led by application security solutions and segmentation solutions from our Guardicore acquisition, and more recently, increased sales of our compute solutions primarily attributable to our acquisition of Linode in the first quarter of 2022, have made a significant contribution to revenue growth. During 2022, security and compute revenue represented over half of our total revenue. We plan to continue to invest in these areas with a focus on further enhancing our product portfolios and extending our go-to-market capabilities, particularly in certain markets and through our channel partners.

•During 2020 and early 2021, we saw a dramatic increase in traffic growth on our network due to the shutdowns and restrictions related to the COVID-19 pandemic. While traffic on our network continues to grow as compared to prior years, the rate of traffic growth has decelerated. Our delivery revenue was negatively impacted by the deceleration, which we believe is partly due to the rollback of COVID-19 pandemic-related restrictions. We expect traffic growth rates in 2023 to continue to be below historical levels as we and other companies manage through a time of economic headwinds and uncertainty.

•The prices paid by some of our customers have declined in recent years due to competition and contract renewals, which negatively impacts our revenue growth rates. We have been able to mitigate some of the negative impacts to our revenue growth rates by upselling incremental solutions to our existing customers. We are taking steps to try to maintain alignment between customer traffic volumes and unit pricing.

•Revenue from our international operations has generally been growing at a faster pace in recent years than from our U.S. operations, particularly from cross-selling of incremental solutions. Because we publicly report in U.S. dollars, and due to the strengthening U.S. dollar, our reported revenue results have been negatively impacted during 2022.

25

•We have experienced variations in certain types of revenue from quarter to quarter. In particular, we typically experience higher revenue in the fourth quarter of each year for some of our solutions as a result of holiday season activity. In addition, we experience quarterly variations in revenue attributable to, among other things, the nature and timing of software and gaming releases by our customers; whether there are large live sporting or other events or situations that impact the amount of media traffic on our network; the timing of large customer contract renewals; and the frequency and timing of purchases of custom solutions or licensed software.

Expenses

Our level of profitability is also impacted by our expenses, including direct costs to support our revenue such as bandwidth and co-location costs, which includes energy to power our network. We have observed the following trends related to our profitability in recent years:

•Network bandwidth costs represent a significant portion of our cost of revenue. Historically, we have been able to mitigate increases in these costs by reducing our network bandwidth costs per unit and investing in internal-use software development to improve the performance and efficiency of our network. We will need to continue to effectively manage our bandwidth costs to maintain current levels of profitability.

•Co-location costs are also a significant portion of our cost of revenue. As we build out our new compute locations to provide us with the ability to scale our platform, we expect to enter into longer term leases that include certain financial commitments in order to achieve more favorable unit economics. The costs of the financial commitments are straight-lined over the life of the lease. We continue to improve our internal-use software and remain disciplined in managing our hardware deployments, particularly for our delivery platform, which enables us to use servers more efficiently. With these efficiencies we have been able to minimize the impact of rising energy costs, particularly in Europe. We expect to continue to scale our network in the future, which will allow us to continue to effectively manage our co-location costs to maintain current levels of profitability.

•Network build-out and supporting service costs represent another significant portion of our cost of revenue. These costs include maintenance and supporting services incurred as we continue to build-out our compute infrastructure and maintain our global network, and costs of third-party cloud providers used for some of our operations. We have seen these costs increase in recent years, as a result of our network expansion and increased use of third-party cloud services. We expect this trend to continue in the near-term as we invest in our network to support our compute solutions, including migrating from third-party cloud providers to our own cloud solutions. We will need to effectively manage our network build-out and supporting costs to maintain current levels of profitability.

•Our employees are core to the operations of our business, and payroll and related costs, including stock-based compensation, is one of our largest expenses. It is important to the success of operations that we offer competitive compensation packages. However, we remain disciplined in allocating our resources to support our faster growing security and compute solutions, including maintaining operational efficiencies to mitigate the rising cost of talent. We are prioritizing our hiring to our high growth areas. In addition, we are re-tasking certain employees to develop, deploy and support go-to-market efforts for our compute solutions.

•Depreciation expense related to our network equipment also contributes to our overall expense levels. In recent years we have invested in our network as traffic levels have increased, which increased our capital expenditures and resulting depreciation expense. We plan to continue to make investments in capital expenditures, however, the focus is to further invest in support of our faster growing compute solutions. Due to the software and hardware initiatives we have undertaken to manage our global network more efficiently, we expect the useful lives of our network servers to be extended. As a result of our expected investments in our network, particularly with respect to cloud computing, we expect depreciation to increase, which will be partially offset by the expected change in useful lives of our network servers.

•Growth in our international operations incrementally increases our exposure to foreign currency fluctuations. In 2022, due to the strengthening U.S. dollar, our expenses that are denominated in foreign currencies have been positively impacted and partially offset the negative impact on revenue, resulting in a negative overall impact on our operating margins.

Recent Acquisitions

In March 2022, we acquired all of the outstanding equity interests of Linode for $898.5 million in cash. Linode is an infrastructure-as-a-service platform provider that allows for developer-friendly cloud computing capabilities. The acquisition is intended to enhance our computing services by enabling us to create a unique cloud platform to build, run and secure applications from the cloud to the edge. Linode had approximately 250 employees when we completed the acquisition.

In October 2021, we acquired Guardicore for $610.7 million in cash. Guardicore's micro-segmentation solution is designed to limit user access to only those applications that are authorized to communicate with each other, thereby limiting the spread of malware and protecting the flow of enterprise data across the network. Guardicore had approximately 270 employees when we completed the acquisition, and the acquisition was dilutive to our earnings per share in 2022.

Remote Work

In May 2022, we launched our FlexBase program, which allows the more than 95% of our workforce designated as flexible to choose whether they want to work from an Akamai office, their home office or a combination of both. Our operations have not been significantly disrupted by the shift to remote working. While we have incurred and expect to continue to incur expenses associated with enabling remote work, reconfiguring work spaces and re-thinking our facility footprint and the way we utilize office space, we do not currently believe those costs will materially impact our financial condition or results of operations.

Global Developments

Since the start of 2022, several global macroeconomic and geopolitical developments have emerged. These developments impacted our traffic growth rates, and as a result, our revenue growth rates. We have experienced a decline in revenue in 2022 related to the war in Ukraine due to a decrease in traffic in Russia, Belarus and Ukraine. Approximately 1% of our 2021 revenue was generated from traffic we served into these countries, and we experienced a decline in revenue in 2022 due to a decrease in traffic in these countries. Additionally, we were negatively impacted by the strengthening of the U.S. dollar. In addition, we, along with our customers, continue to manage through an uncertain period of inflation, growing recessionary concerns, supply chain challenges, uncertain energy supplies, heightened geopolitical tensions and rising interest rates. As a result of the uncertain macroeconomic environment, we have experienced elongated sales cycles with our customers and prospects, and expect to continue to experience elongated sales cycles in 2023. Our board of directors is continuing to oversee risks related to macroeconomic and geopolitical developments, including the ongoing war in Ukraine, and management is monitoring these developments, including the potential impact from the war or other geopolitical events on our business. As a result of overall macroeconomic trends, growing concerns of a potential global recession and future projections of traffic consumption that suggest traffic growth will moderate as restrictions related to the COVID-19 pandemic are lifted, we anticipate our traffic will grow, but at a more moderate pace than we have experienced previously. The extent of the ongoing impact of these macroeconomic events on our business and on global economic activity may continue to adversely affect our business, operations and financial results.

The increases in our revenue in 2022 as compared to 2021, and 2021 as compared to 2020, was primarily the result of continued strong growth in sales of our security solutions, in addition to growth in compute solutions. The increase in 2022 as compared to 2021 was negatively impacted by the significant strengthening of the U.S. dollar and a decline in revenue from our delivery solutions.

The increase in security solutions revenue for 2022 as compared to 2021, was due to growth in a number of key products in our security solutions portfolio, including our application security portfolio, driven by application and application performance interfaces protection, as well as our Zero Trust Enterprise portfolio, which is led by our Guardicore segmentation solution. The increase in security solutions revenue in 2021 as compared to 2020, was due to growth across our security products portfolio, including Bot Manager, Kona Site Defender, Prolexic and our access control product suite.

28

The decrease in delivery solutions revenue for 2022 as compared to 2021 was due to reduction in traffic growth, particularly among our largest customers, which we believe was attributed to macroeconomic challenges our customers are experiencing and the pricing impact of some large renewals that we completed in the first half of the year. The decrease in delivery solutions revenue for 2021 as compared to 2020 was due to reduction in sales of application performance solutions, partially offset by growth in edge application solutions.

The increase in compute solutions revenue in 2022 as compared to 2021 was due to strong growth in compute products, including through the acquisition of Linode in the first quarter of 2022, and continued growth in cloud optimization solutions. Revenue attributable to Linode since the date of the acquisition, and included in our consolidated statements of income, for the year ended 2022 was $103.5 million. The increase in compute solutions revenue in 2021 as compared to 2020, was due to strong growth in cloud optimization solutions.

Revenue derived in the U.S. and internationally during the periods presented is as follows (in thousands):

For each of the years ended December 31, 2022 and 2021, approximately 47% of our revenue was derived from our operations located outside of the U.S., compared to 44% for the year ended December 31, 2020. No single country outside of the U.S. accounted for 10% or more of revenue during any of these periods. We have generally seen revenue growth across all our international regions. Changes in foreign currency exchange rates negatively impacted our revenue by $122.1 million in 2022 as compared to 2021, and positively impacted our revenue by $28.8 million in 2021 as compared to 2020.

The increases in cost of revenue for 2022 as compared to 2021, and 2021 as compared to 2020, was primarily due to increased network build-out and supporting services, particularly related to increased supporting services for third-party cloud applications, and increased investment in our network in prior years to support traffic growth, which resulted in higher depreciation costs of our network equipment and growth in expenses related to our co-location facilities including energy to power our network. The increase in cost of revenue for 2022 as compared to 2021 was also due to increased payroll and related costs as a result of increased headcount due to the acquisition of Linode.

During 2023, we expect our cost of revenue to increase as compared to 2022, in particular co-location costs, due to investments in our network to support the continued growth of our compute solutions. We plan to continue to focus our efforts on managing our operating margins, including our bandwidth and network build-out costs. In particular, we are taking steps to shift workloads to our own cloud solutions, which we expect will reduce third-party cloud application expense. We also expect to change the estimated useful lives of our network servers from five to six years due to software and hardware initiatives we have undertaken to manage our global network more efficiently. This change will partially offset our expected increase in depreciation expense related to our investment in network equipment.

Research and Development Expenses

Research and development expenses consisted of the following for the periods presented (in thousands):

	For the Years Ended December 31,								For the Years Ended December 31,
	2022			2021			% Change		2021			2020			% Change
Payroll and related costs	$	468,928		$	456,138		2.8	%	$	456,138		$	410,568		11.1	%

Capitalized salaries and related costs	(183,540)			(200,530)			(8.5)		(200,530)			(200,143)			0.2
Acquisition-related costs	2,832			—			100.0		—			—			—
Other expenses	25,098			13,813			81.7		13,813			10,036			37.6
Total research and development	$	391,434		$	335,372		16.7	%	$	335,372		$	269,315		24.5	%
As a percentage of revenue	10.8		%	9.7		%			9.7		%	8.4		%

The increase in research and development expenses for 2022 as compared to 2021 was due to higher payroll and related costs and related stock-based compensation as a result of headcount growth from employees joining us through acquisitions, a reduction in capitalized salaries and related costs as a result of a shift in resources to work on core maintenance activities related to our platform and an increase in other expenses due to an increase in the use of third-party cloud applications to support our research and development activities.

The increase in research and development expenses for 2021 as compared to 2020 was due to increased payroll and related costs, including stock-based compensation, primarily due to headcount growth, the redeployment of some employees to research and development functions from sales and marketing activities as part of our March 2021 reorganization and as a result of employees joining us through acquisitions.

Research and development costs are expensed as incurred, other than certain internal-use software development costs eligible for capitalization. Capitalized development costs consist of payroll and related costs for personnel and external consulting expenses involved in the development of internal-use software used to deliver our services and operate our network. For the years ended December 31, 2022, 2021 and 2020, we capitalized $30.0 million, $32.2 million and $35.7 million, respectively, of stock-based compensation. These capitalized internal-use software development costs are amortized to cost of revenue over their estimated useful lives, ranging from two to seven years based on the software developed and its expected useful life.

We expect research and development costs to increase in 2023, in particular payroll and related costs and stock-based compensation, to support the continued growth of our compute and security solutions.

Sales and Marketing Expenses

Sales and marketing expenses consisted of the following for the periods presented (in thousands):

	For the Years Ended December 31,								For the Years Ended December 31,
	2022			2021			% Change		2021			2020			% Change
Payroll and related costs	$	374,110		$	366,501		2.1	%	$	366,501		$	393,800		(6.9)	%
Stock-based compensation	47,789			46,342			3.1		46,342			65,257			(29.0)
Marketing programs and related costs	55,033			40,553			35.7		40,553			39,272			3.3
Acquisition-related costs	2,166			—			100.0		—			—			—
Other expenses	23,311			8,571			172.0		8,571			12,076			(29.0)
Total sales and marketing	$	502,409		$	461,967		8.8	%	$	461,967		$	510,405		(9.5)	%
As a percentage of revenue	13.9		%	13.3		%			13.3		%	16.0		%

The increase in sales and marketing expenses for 2022 as compared to 2021 was primarily due to increased marketing programs and related costs due to advertising and customer events held in 2022. Other expenses also increased due to travel associated with customer events and meetings, as well as a sales recognition event during 2022 that did not occur in 2021. Such events and travel costs were higher in 2022 than in 2021 due to the rollback of COVID-19 pandemic-related restrictions that had been in place in the prior year.

The decrease in sales and marketing expenses for 2021 as compared to 2020 was due to decreased payroll and related costs, including stock-based compensation, primarily as a result of headcount reductions due to the establishment of a unified global sales organization and elimination of duplicative roles. In addition, some employees who previously supported the sales organization were redeployed in 2021 to our research and development function to focus our investments to improve security, performance, scalability and innovation across our solutions.

We expect sales and marketing costs to increase in 2023 as compared to 2022, due to our continued investment in go-to-market efforts. However, we plan to continue to carefully manage costs in an effort to manage our operating margins.

General and Administrative Expenses

General and administrative expenses consisted of the following for the periods presented (in thousands):

As a percentage of revenue	16.2		%	16.0		%			16.0		%	17.1		%

The increase in general and administrative expenses for 2022 as compared to 2021 was primarily due to software and related service costs as we transition and expand to cloud-based applications, other expenses related to an increase in

31

professional service fees to support our operations and acquisition-related costs primarily related to our acquisition of Linode. These increases were partially offset by a decrease in payroll and related costs due to a decline in performance-based compensation programs.

The increase in general and administrative expenses for 2021 as compared to 2020 was primarily due to increased payroll and related costs, including stock-based compensation, as a result of annual merit increases and headcount growth, partially offset by a decrease in an endowment contribution to the Akamai Foundation in 2020 that did not recur in 2021.

General and administrative expenses for 2022, 2021 and 2020 are broken out by category as follows (in thousands):

	For the Years Ended December 31,								For the Years Ended December 31,

As a percentage of revenue	16.2		%	16.0		%			16.0		%	17.1		%

Global functions expense includes payroll, stock-based compensation and other employee-related costs for administrative functions, including finance, purchasing, order entry, human resources, legal, information technology and executive personnel, as well as third-party professional service fees. Infrastructure expense includes payroll, stock-based compensation and other employee-related costs for our network infrastructure functions, as well as facility rent expense, depreciation and amortization of facility and IT-related assets, software and related service costs, business insurance and taxes. Our network infrastructure function is responsible for network planning, sourcing, architecture evaluation and platform security. Other expense includes acquisition-related costs, provision for doubtful accounts, legal settlements and the endowment contribution to the Akamai Foundation.

During 2023, we expect our general and administrative expenses to increase as compared to 2022 as a result of payroll and related costs, including stock-based compensation, due to the expected achievement of the performance-based compensation programs. We plan to continue to control costs, including reducing our real estate expenses due to excess capacity created by our FlexBase program, in an effort to manage our operating margins.

Amortization of Acquired Intangible Assets

The restructuring charge for 2022 was primarily related to software impairment charges related to our investment with Mitsubishi UFJ Financial Group ("MUFG") in the joint venture Global Open Network, Inc. ("GO-NET"), and MUFG's decision to suspend GO-NET's operations, and impairments of right-of-use-assets for facilities that are no longer needed as a result of our FlexBase program.

The restructuring charge in 2021 was primarily the result of management's actions initiated in the fourth quarter of 2020 to better position us to become more agile in delivering our solutions. The restructuring charge for this action includes severance and related expenses for certain headcount reductions and software charges for software not yet placed into service that will not be implemented due to this action. In addition to the 2020 action, additional charges were incurred in 2021, related to management’s plans to launch its new FlexBase program in May 2022. The restructuring charge incurred for this program in 2021 includes impairments of lease-related assets for certain facilities that are no longer needed. These restructuring charges were partially offset by the release of a lease obligation for a facility previously exited as part of management actions initiated in late 2019.

The restructuring charge in 2020 was primarily the result of the management actions initiated in the fourth quarter of 2020, and the associated severance and related expenses and software charges that resulted from the action. In addition, an $8.7 million impairment of lease-related assets was incurred during 2020 to exit leased facilities related to a 2019 action, which allowed us to focus on investment with the potential to accelerate new revenue growth.

We are continuing to evaluate our facility footprint in light of our FlexBase program, including our plans and ability to sublease space, but we do not currently believe such charges will materially impact our financial condition or results of operation.

Interest and marketable securities income, net primarily consists of interest earned on invested cash and marketable securities balances and income and losses on mutual funds that are associated with our employee non-qualified deferred compensation plan. The decrease to interest and marketable securities income, net for 2022 as compared to 2021 was due to increased losses associated with the non-qualified deferred compensation plan and lower interest earned on invested cash balances and marketable securities as a result of lower marketable securities balances in 2022 due to the funding of our recent acquisitions. The decrease to interest and marketable securities, net for 2021 as compared to 2020 was primarily the result of investing in marketable securities having lower rates of return due to lower interest rates.

Interest expense is related to our debt transactions, which are described in Note 11 to the consolidated financial statements included elsewhere in this annual report on Form 10-K. The decrease to interest expense for 2022 as compared to 2021 was the result of the adoption of the new guidance for accounting for convertible senior notes on January 1, 2022, which resulted in the elimination of the amortization of debt discounts.

Other (expense) income, net primarily represents net foreign exchange gains and losses mainly due to foreign exchange rate fluctuations on intercompany transactions and other non-operating expense and income items as well as gains and losses on equity investments. Other (expense) income, net for the year ended December 31, 2022 includes an $8.9 million impairment from an equity investment, partially offset by a favorable impact of changes in foreign currency exchange rates. Other (expense) income, net for the years ended December 31, 2021 and 2020 also includes gains from the sale of equity investments of $3.7 million and $7.2 million, respectively. Other income (expense), net may fluctuate in the future based on changes in foreign currency exchange rates or other events.

Provision for Income Taxes

	For the Years Ended December 31,								For the Years Ended December 31,
(in thousands)	2022			2021			% Change		2021			2020			% Change
Provision for income taxes	$	126,696		$	62,571		102.5	%	$	62,571		$	45,922		36.3	%
As a percentage of revenue	3.5		%	1.8		%			1.8		%	1.4		%
Effective income tax rate	19.3		%	8.6		%			8.6		%	7.5		%

The increase in the provision for income taxes for 2022 as compared to 2021 was mainly due to an intercompany sale of intellectual property, an increase in the tax on global intangible low-taxed income, a decrease in foreign income taxed at lower rates and a decrease in the excess tax benefit related to stock-based compensation. These amounts were partially offset by a decrease in profitability.

The increase in the provision for income taxes for 2021 as compared to 2020 was mainly due to an increase in profitability and a decrease in the excess tax benefit related to stock-based compensation. These amounts were partially offset by an increase in foreign income taxed at lower rates, a decrease in state taxes, a decrease in the revaluation of certain foreign income tax liabilities due to foreign exchange rate fluctuations and the release of certain tax reserves related to the expiration of local statutes of limitations.

For the year ended December 31, 2022, our effective income tax rate was lower than the federal statutory tax rate due to foreign income taxed at lower rates and the benefit of U.S. federal, state and foreign research and development credits. These amounts were partially offset by non-deductible stock-based compensation, tax on global intangible low-taxed income and an intercompany sale of intellectual property.

For the year ended December 31, 2021, our effective income tax rate was lower than the federal statutory tax rate due to foreign income taxed at lower rates, the excess tax benefit related to stock-based compensation and the benefit of U.S. federal, state and foreign research and development credits. These amounts were partially offset by non-deductible stock-based compensation and state taxes.

For the year ended December 31, 2020, our effective income tax rate was lower than the federal statutory tax rate due to foreign income taxed at lower rates, the impact of the excess tax benefit related to stock-based compensation and the benefit of U.S. federal, state and foreign research and development credits. These amounts were partially offset by non-deductible stock-based compensation, state taxes and the valuation allowance recorded against tax credits and foreign net operating loss carryforwards.

Our effective income tax rate may fluctuate between fiscal years and from quarter to quarter due to items arising from discrete events, such as tax benefits from the settlement of employee equity awards, tax law changes and settlements of tax audits and assessments. Our effective income tax rate is also impacted by, and may fluctuate in any given period because of, the composition of income in foreign jurisdictions where tax rates differ depending on the local statutory rates.

Refer to Note 19 to the consolidated financial statements included elsewhere in this annual report on Form 10-K for additional information regarding unrecognized tax benefits that, if recognized, would impact the effective income tax rate in the next 12 months.

Loss from Equity Method Investment

Loss from equity method investment includes our share of losses from our investment with MUFG in the joint venture GO-NET, in addition to impairment charges realized. Since MUFG made the decision to suspend operations and ultimately liquidate GO-NET during 2022, our final impairment charge, which reduced our investment value to zero, was recognized during 2022.

Non-GAAP Financial Measures

In addition to providing financial measurements based on generally accepted accounting principles in the United States of America ("GAAP") we provide additional financial metrics that are not prepared in accordance with GAAP ("non-GAAP financial measures"). Management uses non-GAAP financial measures to understand and compare operating results across accounting periods, for financial and operational decision making, for planning and forecasting purposes, to measure executive compensation and to evaluate our financial performance. These non-GAAP financial measures are non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income, non-GAAP net income per diluted share, Adjusted EBITDA, Adjusted EBITDA margin, capital expenditures and impact of foreign currency exchange rates, as discussed below.

Management believes that these non-GAAP financial measures reflect our ongoing business in a manner that allows for meaningful comparisons and analysis of trends in the business, as they facilitate comparing financial results across accounting periods and to those of peer companies. Management also believes that these non-GAAP financial measures enable investors to evaluate our operating results and future prospects in the same manner as management. These non-GAAP financial measures may exclude expenses and gains that may be unusual in nature, infrequent or not reflective of our ongoing operating results.

The non-GAAP financial measures do not replace the presentation of our GAAP financial measures and should only be used as a supplement to, not as a substitute for, our financial results presented in accordance with GAAP.

The non-GAAP adjustments, and our basis for excluding them from non-GAAP financial measures, are outlined below:

•Amortization of acquired intangible assets – We have incurred amortization of intangible assets, included in our GAAP financial statements, related to various acquisitions we have made. The amount of an acquisition's purchase price allocated to intangible assets and term of its related amortization can vary significantly and is unique to each acquisition; therefore, we exclude amortization of acquired intangible assets from our non-GAAP financial measures to provide investors with a consistent basis for comparing pre- and post-acquisition operating results.

•Stock-based compensation and amortization of capitalized stock-based compensation – Although stock-based compensation is an important aspect of the compensation paid to our employees, the grant date fair value varies based on the stock price at the time of grant, varying valuation methodologies, subjective assumptions and the variety of award types. This makes the comparison of our current financial results to previous and future periods difficult to interpret; therefore, we believe it is useful to exclude stock-based compensation and amortization of capitalized stock-based compensation from our non-GAAP financial measures in order to highlight the performance of our core business and to be consistent with the way many investors evaluate our performance and compare our operating results to peer companies.

•Acquisition-related costs – Acquisition-related costs include transaction fees, advisory fees, due diligence costs and other direct costs associated with strategic activities, as well as certain additional compensation costs payable to employees acquired from the Linode acquisition if employed for a certain period of time. The additional compensation cost was initiated by and determined by the seller, and is in addition to normal levels of compensation, including retention programs, offered by Akamai. Acquisition-related costs are impacted by the timing and size of the acquisitions. We exclude acquisition-related costs from our non-GAAP financial measures to provide a useful comparison of our operating results to prior periods and to our peer companies because such amounts vary significantly based on the magnitude of our acquisition transactions and do not reflect our core operations.

•Restructuring charge – We have incurred restructuring charges from programs that have significantly changed either the scope of the business undertaken by us or the manner in which that business is conducted. These charges include severance and related expenses for workforce reductions, impairments of long-lived assets that will no longer be used in operations (including right-of-use assets, other facility-related property and equipment and internal-use software) and termination fees for any contracts cancelled as part of these programs. We exclude these items from our non-GAAP financial measures when evaluating our continuing business performance as such items vary significantly based on the magnitude of the restructuring action and do not reflect expected future operating expenses. In addition, these charges do not necessarily provide meaningful insight into the fundamentals of current or past operations of our business.

35

•Amortization of debt discount and issuance costs and amortization of capitalized interest expense – In August 2019, we issued $1,150 million of convertible senior notes due 2027 with a coupon interest rate of 0.375%. In May 2018, we issued $1,150 million of convertible senior notes due 2025 with a coupon interest rate of 0.125%. The imputed interest rates of these convertible senior notes were 3.10% and 4.26%, respectively. This is a result of the debt discounts recorded for the conversion features that, prior to January 1, 2022, were required to be separately accounted for as equity under GAAP, thereby reducing the carrying values of the convertible debt instruments. The debt discounts were amortized as interest expense. On January 1, 2022, we adopted the new guidance for accounting for convertible instruments. This new guidance eliminated separate accounting for the equity portion, and thus the amortization of the debt discount that was recorded as interest expense. Prior to January 1, 2022, we excluded this non-cash interest expense from our non-GAAP results because it was not representative of ongoing operating performance. After January 1, 2022, this interest expense is no longer included in or excluded from GAAP or non-GAAP results. Additionally, the issuance costs of the convertible senior notes are amortized to interest expense and are also excluded from our non-GAAP results because we believe the non-cash amortization expense is not representative of ongoing operating performance.

•Gains and losses on investments – We have recorded gains and losses from the disposition, changes to fair value and impairment of certain investments. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the types of events giving rise to these gains and losses are not representative of our core business operations and ongoing operating performance.

•Legal settlements – We have incurred losses related to the settlement of legal matters. We believe excluding these amounts from our non-GAAP financial measures is useful to investors as the types of events giving rise to them are not representative of our core business operations.

•Endowment of Akamai Foundation – We have incurred expenses to endow the Akamai Foundation, a private corporate foundation dedicated to encouraging the next generation of technology innovators by supporting math and science education. Our first endowment was in 2018 to enable a permanent endowment for the Akamai Foundation to allow it to expand its reach. In the fourth quarter of 2020 we supplemented the endowment to enable specific initiatives to increase diversity in the technology industry. We believe excluding these amounts from non-GAAP financial measures is useful to investors as these infrequent expenses are not representative of our core business operations.

•Income and losses from equity method investment – We record income or losses on our share of earnings and losses from our equity method investment. We exclude such income and losses because we do not have direct control over the operations of the investment and the related income and losses are not representative of our core business operations.

•Income tax effect of non-GAAP adjustments and certain discrete tax items – The non-GAAP adjustments described above are reported on a pre-tax basis. The income tax effect of non-GAAP adjustments is the difference between GAAP and non-GAAP income tax expense. Non-GAAP income tax expense is computed on non-GAAP pre-tax income (GAAP pre-tax income adjusted for non-GAAP adjustments) and excludes certain discrete tax items (such as recording or releasing of valuation allowances), if any. We believe that applying the non-GAAP adjustments and their related income tax effect allows us to highlight income attributable to our core operations.

Shares used in non-GAAP per diluted share calculations (1)	159,747		164,204		164,340

(1) Shares used in non-GAAP per diluted share calculations have been adjusted for the periods presented for the benefit of our note hedge transactions. During the periods presented, our average stock price was in excess of $95.10, which is the initial conversion price of our convertible senior notes due in 2025. See further discussion below.

(2) May not foot due to rounding.

Non-GAAP net income per diluted share is calculated as non-GAAP net income divided by diluted weighted average common shares outstanding. GAAP diluted weighted average common shares outstanding are adjusted in non-GAAP per share calculations for the shares that would be delivered to us pursuant to the note hedge transactions entered into in connection with the issuance of our convertible senior notes. Under GAAP, shares delivered under hedge transactions are not considered offsetting shares in the fully-diluted share calculation until they are delivered. However, we would receive a benefit from the note hedge transactions and would not allow the dilution to occur, so management believes that adjusting for this benefit provides a meaningful view of net income per share. Unless our weighted average stock price is greater than $95.10, the initial conversion price of the convertible senior notes due 2025, or $116.18, the initial conversion price of the convertible senior notes due 2027, there will be no difference between our GAAP and non-GAAP diluted weighted average common shares outstanding.

We consider Adjusted EBITDA to be another important indicator of the operational strength and performance of our business and a good measure of our historical operating trends. Adjusted EBITDA eliminates items that we do not consider to be part of our core operations. We define Adjusted EBITDA as GAAP net income excluding the following items: interest and marketable securities income and losses; income taxes; depreciation and amortization of tangible and intangible assets; stock-based compensation; amortization of capitalized stock-based compensation; acquisition-related costs; restructuring charges; gains and losses on legal settlements; costs incurred related to endowment contributions to the Akamai Foundation; foreign exchange gains and losses; interest expense; amortization of capitalized interest expense; certain gains and losses on investments; income and losses from equity method investments; and other non-recurring or unusual items that may arise from time to time. Adjusted EBITDA margin represents Adjusted EBITDA stated as a percentage of revenue.

Impact of Foreign Currency Exchange Rates

Revenue and earnings from our international operations have historically been an important contributor to our financial results. Consequently, our financial results have been impacted, and management expects they will continue to be impacted, by fluctuations in foreign currency exchange rates. For example, when the local currencies of our foreign subsidiaries weaken, generally our consolidated results stated in U.S. dollars are negatively impacted.

Because exchange rates are a meaningful factor in understanding period-to-period comparisons, management believes the presentation of the impact of foreign currency exchange rates on revenue and earnings enhances the understanding of our financial results and evaluation of performance in comparison to prior periods. The dollar impact of changes in foreign currency exchange rates presented is calculated by translating current period results using monthly average foreign currency exchange rates from the comparative period and comparing them to the reported amount. The percentage change at constant currency presented is calculated by comparing the prior period amounts as reported and the current period amounts translated using the same monthly average foreign currency exchange rates from the comparative period.

Liquidity and Capital Resources

To date, we have financed our operations primarily through public and private sales of debt and equity securities and cash generated by operations. As of December 31, 2022, our cash, cash equivalents and marketable securities, which primarily consisted of time deposits, corporate bonds and U.S. government agency obligations, totaled $1.4 billion. We place our cash investments in instruments that meet high-quality credit standards, as specified in our investment policy. Our investment policy also limits the amount of our credit exposure to any one issue or issuer and seeks to manage these assets to achieve our goals of preserving principal and maintaining adequate liquidity at all times.

Changes in cash, cash equivalents and marketable securities are dependent upon changes in, among other things, working capital items such as accounts receivable, deferred revenue, accounts payable and various accrued expenses, as well as changes in our capital and financial structure due to common stock repurchases, debt repayments and issuances, acquisitions, purchases and sales of marketable securities, cash paid for acquisitions and similar events. We believe that our strong balance sheet and

39

cash position are important competitive differentiators that provide the financial stability and flexibility to enable us to continue to make investments at opportune times. We expect to continue to evaluate strategic investments to strengthen our business.

As of December 31, 2022, we had cash and cash equivalents of $249.5 million held in accounts outside the U.S. The U.S. Tax Cuts and Jobs Act establishes a territorial tax system in the U.S., which provides companies with the potential ability to repatriate earnings with minimal U.S. federal income tax impact. As a result, our liquidity is not expected to be materially impacted by the amount of cash and cash equivalents held in accounts outside the U.S.

The following table summarizes current and long-term material cash requirements as of December 31, 2022, which we expect to fund primarily with operating cash flows (in thousands):

	Payments Due by Period

(1) Excludes $141.7 million of obligations for operating leases that have not yet commenced. See Note 12 to our consolidated financial statements included elsewhere in this annual report on Form 10-K for additional information.

In accordance with the authoritative guidance for accounting for uncertainty in income taxes, as of December 31, 2022, we had unrecognized tax benefits of $38.3 million, including $8.6 million of accrued interest and penalties. We believe that it is reasonably possible that $3.6 million of our unrecognized tax benefits will be recognized by the end of 2023. The settlement period for the remaining amount of the unrecognized tax benefits is unknown.

The decrease in cash provided by operating activities for 2022 as compared to 2021 was primarily due to income taxes paid on an intercompany sale of intellectual property, lower profitability and timing of vendor payments.

The increase in cash provided by operating activities for 2021 as compared to 2020 was primarily due to increased profitability in 2021 and timing of payments from customers.

The decrease in cash used in investing activities in 2022 as compared to 2021 was due to a decrease in purchases of marketable securities, as we did not reinvest our matured securities in order to fund our acquisition of Linode, and a decrease in purchases of property and equipment as we reduced spending related to our delivery solutions as we focused on higher growth initiatives, partially offset by cash paid for the acquisition of Linode in March 2022.

The decrease in cash used in investing activities in 2021 as compared to 2020 was primarily driven by a decrease in purchases of marketable securities, as we did not reinvest our matured securities in order to fund our acquisition of Guardicore in October 2021. The decrease was also attributable to a reduction of purchases of property and equipment as we slowed expansion of our network, as compared to 2020. These decreases were partially offset by an increase in cash paid for acquired businesses in 2021, due to the size of the acquisition completed in 2021 as compared to 2020.

Net cash used in financing activities	$	(634,177)	$	(562,003)	$	(223,641)

The increase in cash used in financing activities in 2022 as compared to 2021, and 2021 as compared to 2020, was primarily the result of increased share repurchases. Effective November 1, 2018, our board of directors authorized a $1.1 billion share repurchase program through December 31, 2021. In October 2021, our board of directors authorized a new $1.8 billion share repurchase program, effective January 1, 2022 through December 31, 2024. Our goals for the share repurchase programs are to offset the dilution created by our employee equity compensation programs over time and provide the flexibility to return capital to shareholders as business and market conditions warrant, while still preserving our ability to pursue other strategic opportunities.

During 2022, 2021 and 2020, we repurchased 6.4 million, 4.7 million and 2.0 million shares of our common stock, respectively, at an average price per share of $94.96, $109.97 and $98.53, respectively.

Convertible Senior Notes

In August 2019, we issued $1,150.0 million in par value of convertible senior notes due 2027 and entered into related convertible note hedge and warrant transactions. We have used and expect to continue to use the net proceeds of the offering for share repurchases, working capital and general corporate purposes, including potential acquisitions and other strategic transactions.

In May 2018, we issued $1,150.0 million in par value of convertible senior notes due 2025 and entered into related convertible note hedge and warrant transactions. We used a portion of the net proceeds to repay at maturity all of our $690.0 million outstanding aggregate principle amount of convertible senior notes due in 2019. In addition, we have used and expect to continue to use the remaining net proceeds of the offering for share repurchases, working capital and general corporate purposes, including potential acquisitions and other strategic transactions.

The terms of the notes and the hedge and warrant transactions are discussed more fully in Note 11 to the consolidated financial statements included elsewhere in this annual report on Form 10-K.

Revolving Credit Facility

In May 2018, we entered into a $500.0 million, five-year revolving credit agreement ("2018 Credit Agreement"). Borrowings under the 2018 Credit Agreement bore interest, at our option, at a base rate plus a spread of 0.00% to 0.25% or an adjusted LIBOR rate plus a spread of 0.875% to 1.25%, in each case with such spread being determined based on our consolidated leverage ratio specified in the 2018 Credit Agreement. Regardless of what amounts, if any, were outstanding under the 2018 Credit Agreement, we were also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.075% to 0.15%, with such rate being based on our consolidated leverage ratio specified in the 2018 Credit Agreement.

In November 2022, we entered into a $500.0 million, five-year revolving credit agreement ("2022 Credit Agreement"). The 2022 Credit Agreement replaces the 2018 Credit Agreement. Borrowings under the 2022 Credit Agreement may be used to finance working capital needs and for general corporate purposes. The 2022 Credit Agreement provides for an initial $500.0 million revolving loans. Under specified circumstances, the facility can be increased to up to $1.0 billion in aggregate principal amount.

Borrowings under the 2022 Credit Agreement bear interest, at our option, and subject to a credit spread adjustment, at a term benchmark rate plus a spread of 0.75% to 1.125%, a reference rate plus a spread of 0.75% to 1.125%, or a base rate plus a spread of 0.00% to 0.125%, in each case with such spread being determined based on our consolidated leverage ratio specified in the 2022 Credit Agreement. Regardless of what amounts, if any, are outstanding under the 2022 Credit Agreement, we are also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.07% to 0.125%, with such rate being based on our consolidated leverage ratio specified in the 2022 Credit Agreement.

The 2022 Credit Agreement contains customary representations and warranties, affirmative and negative covenants and events of default. The negative covenants include restrictions on subsidiary indebtedness, liens and fundamental changes. These covenants are subject to a number of important exceptions and qualifications. The principal financial covenant requires a maximum consolidated leverage ratio. The 2022 Credit Facility expires, and any amounts outstanding thereunder will become due and payable, in November 2027, subject to up to two one-year extensions at our request and with the consent of the lenders party thereto. There were no outstanding borrowings under the 2022 Credit Agreement as of December 31, 2022. 

Liquidity Outlook

Based on our present business plan, we expect our current cash, cash equivalents and marketable securities balances and our forecasted cash flows from operations to be sufficient to meet our foreseeable cash needs for at least the next 12 months. Our foreseeable cash needs, in addition to our recurring operating costs, include our expected capital expenditures, investments in information technology, potential strategic acquisitions, anticipated share repurchases, lease and purchase commitments and settlements of other liabilities.

Off-Balance Sheet Arrangements

We have entered into indemnification agreements with third parties, including vendors, customers, landlords, our officers and directors, shareholders of acquired companies, joint venture partners and third parties to which we license technology. Generally, these indemnification agreements require us to reimburse losses suffered by a third party due to various events, such as lawsuits arising from patent or copyright infringement or our negligence. These indemnification obligations are considered off-balance sheet arrangements in accordance with the authoritative guidance for guarantor’s accounting and disclosure requirements for guarantees, including indirect guarantees of indebtedness of others. See Note 13 to our consolidated financial statements included elsewhere in this annual report on Form 10-K for further discussion of these indemnification agreements. The fair value of guarantees issued or modified during 2022 and 2021 was determined to be immaterial.

Application of Critical Accounting Policies and Estimates

Overview

Our MD&A is based upon our consolidated financial statements, which have been prepared in accordance with GAAP. These principles require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, cash flow and related disclosure of contingent assets and liabilities. Our estimates include those related to revenue recognition, accounts receivable and related reserves, valuation and impairment of marketable securities, capitalized internal-use software development costs, goodwill and acquired intangible assets, income tax reserves, impairment and useful lives of long-lived assets and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances at the time such estimates are made. Actual results may differ from these estimates. For a complete description of our significant accounting policies, see Note 2 to our consolidated financial statements included elsewhere in this annual report on Form 10-K.

Definitions

We define our critical accounting policies as those policies that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our consolidated financial statements. Our estimates are based upon assumptions and judgments about matters that are highly uncertain at the time an accounting estimate is made and applied and require us to assess a range of potential outcomes.

Review of Critical Accounting Policies and Estimates

Revenue Recognition

Our contracts with customers sometimes include promises to transfer multiple services to a customer. Determining whether services are distinct performance obligations often requires the exercise of judgment by management. Advanced features that enhance a main product or service and are highly interrelated are generally not considered distinct; rather, they are combined with the service they relate to into one performance obligation. Different determinations related to combining services into performance obligations could result in differences in the timing and amount of revenue recognized in a period.

Determination of the standalone selling price ("SSP") also requires the exercise of judgment by management. SSP is based on observable inputs such as the price we charge for the service when sold separately, or the discounted list price per management’s approved price list. In cases where services are not sold separately or price list rates are not available, a cost-plus-margin approach or adjusted market approach is used to determine SSP. Changes to SSP could result in differences in the allocation of transaction price among performance obligations, which could result in differences in the timing and amount of revenue recognized in a period.

From time to time, we enter into contracts to sell services or license technology to unrelated enterprises at or about the same time that we enter into contracts to purchase products or services from the same enterprises. Consideration payable to a customer is reviewed as part of the transaction price. If the payment to the customer does not represent payment for a distinct service, revenue is recognized only up to the net amount of consideration after customer payment obligations are considered. Different determinations on whether a payment represents a distinct service could result in differences in the amount of revenue recognized.

We may also resell the licenses or services of third parties. If we are acting as an agent in an arrangement with a customer to provide third party services, the transaction price reflects only the net amount to which we will be entitled, after accounting for payments made to the third party responsible for satisfying the performance obligation. Different determinations on whether we are acting as an agent or a principal could change the amount of revenue recognized.

Accounts Receivable and Related Reserves

Trade accounts receivable are recorded at the invoiced amounts and do not bear interest. In addition to trade accounts receivable, our accounts receivable balance includes unbilled accounts that represent revenue recorded for customers that is typically billed within one month. We record allowances against our accounts receivable balance, primarily for current expected credit losses. Increases and decreases in the allowance for current expected credit losses are included as a component of general and administrative expense in the consolidated statements of income.

43

Estimates are used in determining our allowance for current expected credit losses using historical loss rates for the previous twelve months as well as expectations about the future where we have been able to develop forecasts to supports our estimates. In addition, the allowance for current expected credit losses considers outstanding balances on a customer-specific, account-by-account basis. We assess collectability based upon a review of customer receivables from prior sales with collection issues where we no longer believe that the customer has the ability to pay for services previously provided. We also perform ongoing credit evaluations of our customers. If such an evaluation indicates that payment is no longer reasonably assured for services provided, any future services provided to that customer will result in the creation of a cash basis reserve until we receive consistent payments.

Valuation and Impairment of Marketable Securities

We measure the fair value of our financial assets and liabilities at the end of each reporting period. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We have certain financial assets and liabilities recorded at fair value (principally cash equivalents and short- and long-term marketable securities) that have been classified as Level 1, 2 or 3 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we can access at the reporting date. Fair values determined by Level 2 inputs utilize data points other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair values determined by Level 3 inputs are based on unobservable data points for the asset or liability.

Marketable securities are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. We periodically evaluate whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors, the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health of, and business outlook for, the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends; and our intent and ability to retain our investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Assessing the above factors involves inherent uncertainty. Write-downs, if recorded, could be materially different from the actual market performance of marketable securities in our portfolio if, among other things, relevant information related to our investments and marketable securities was not publicly available or other factors not considered by us would have been relevant to the determination of impairment.

Impairment and Useful Lives of Long-Lived Assets

We review our long-lived assets, such as property and equipment, operating lease right-of-use assets and acquired intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Events that would trigger an impairment review include a change in the use of the asset or forecasted negative cash flows related to the asset. When such events occur, we compare the carrying amount of the asset to the undiscounted expected future cash flows related to the asset. If this comparison indicates that impairment is present, the amount of the impairment is calculated as the difference between the carrying amount and the fair value of the asset. If a readily determinable market price does not exist, fair value is estimated using discounted expected cash flows attributable to the asset. The estimates required to apply this accounting policy include forecasted usage of the long-lived assets, the useful lives of these assets and expected future cash flows. Changes in these estimates could materially impact results from operations.

Goodwill and Acquired Intangible Assets

We test goodwill for impairment on an annual basis, as of December 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. We have concluded that we have one reporting unit and that our chief operating decision maker is our chief executive officer and the executive management team. We have assigned the entire balance of goodwill to our one reporting unit. The fair value of the reporting unit was based on our market capitalization as of each of December 31, 2022 and 2021, and it was substantially in excess of the carrying value of the reporting unit at each date.

Acquired intangible assets consist of completed technologies, customer relationships, trademarks and trade names, non-compete agreements and acquired license rights. We engage third party valuation specialists to assist us with the initial measurement of the fair value of acquired intangible assets. Fair value and useful life determinations may be based on, among other factors, estimates of future expected cash flows, royalty cost savings and appropriate discount rates used in calculating present values. Acquired intangible assets, other than goodwill, are amortized over their estimated useful lives based upon the estimated economic value derived from the related intangible assets.

44

Income Taxes

    Our provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated for the estimated future tax effects attributable to temporary differences and carryforwards by using expected tax rates in effect in the years during which the differences are expected to reverse or the carryforwards are expected to be realized.

We currently have net deferred tax assets, comprised of net operating loss, or NOL, carryforwards, tax credit carryforwards and deductible temporary differences. Our management periodically weighs the positive and negative evidence to determine if it is more-likely-than-not that some or all of the deferred tax assets will be realized. In determining our net deferred tax assets and valuation allowances, annualized effective tax rates and cash paid for income taxes, management is required to make judgments and estimates about domestic and foreign profitability, the timing and extent of the utilization of NOL carryforwards, applicable tax rates, transfer pricing methodologies and tax planning strategies. Judgments and estimates related to our projections and assumptions are inherently uncertain; therefore, actual results could differ materially from our projections.

We have recorded certain tax reserves to address potential exposures involving our income tax positions. These potential tax liabilities result from the varying application of statutes, rules, regulations and interpretations by different taxing jurisdictions. Our estimate of the value of our tax reserves contains assumptions based on past experiences and judgments about the interpretation of statutes, rules and regulations by taxing jurisdictions. It is possible that the costs of the ultimate tax liability or benefit from these matters may be more or less than the amount that we estimated.

Uncertainty in income taxes is recognized in our consolidated financial statements using a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained based on technical merit, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that we believe has a greater than 50% likelihood of being realized upon ultimate settlement.

Accounting for Stock-Based Compensation

We issue stock-based compensation awards including stock options, restricted stock, restricted stock units and deferred stock units. We measure the fair value of these awards at the grant date and recognize such fair value as expense over the vesting period. We have selected the Black-Scholes option pricing model to determine the fair value of stock option awards and the Monte Carlo simulation model to determine the fair value of market-based restricted stock unit awards. Determining the fair value of stock-based awards at the grant date requires judgment, including estimating the expected life of the stock awards and the volatility of the underlying common stock. Our assumptions may differ from those used in prior periods. Changes to the assumptions may have a significant impact on the fair value of stock-based awards, which could have a material impact on our financial statements. Judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Should our actual forfeiture rates differ significantly from our estimates, our stock-based compensation expense and results of operations could be materially impacted. In addition, for awards that vest and become exercisable only upon achievement of specified performance conditions, we make judgments and estimates each quarter about the probability that such performance conditions will be met or achieved. Changes to the estimates we make from time to time may have a significant impact on our stock-based compensation expense and could materially impact our results of operations.

Capitalized Internal-Use Software Costs

We capitalize salaries and related costs, including stock-based compensation, of employees and consultants who devote time to the development of internal-use software development projects, as well as interest expense related to our senior convertible notes. Capitalization begins during the application development stage, once the preliminary project stage has been completed. If a project constitutes an enhancement to previously-developed software, we assess whether the enhancement creates additional functionality to the software, thus qualifying the work incurred for capitalization. Once the project is available for general release, capitalization ceases and we estimate the useful life of the asset and begin amortization. We periodically assess whether triggering events are present to review internal-use software for impairment. Changes in our estimates related to internal-use software would increase or decrease operating expenses or amortization recorded during the period.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our portfolio of cash equivalents and short- and long-term investments is maintained in a variety of securities, including U.S. government agency obligations, commercial paper and high-quality corporate bonds. The majority of our investments are classified as available-for-sale securities and carried at fair market value with cumulative unrealized gains or losses recorded as a component of accumulated other comprehensive loss within stockholders' equity. A sharp rise in interest rates could have an adverse impact on the fair market value of certain securities in our portfolio. We do not currently hedge our interest rate exposure and do not enter into financial instruments for trading or speculative purposes. If market interest rates were to increase by 100 basis points from December 31, 2022 levels, the fair value of our available-for-sale portfolio would decline by approximately $7.0 million.

In August 2019, we issued $1,150.0 million aggregate principal amount of 0.375% convertible senior notes due 2027. In May 2018, we issued $1,150.0 million aggregate principal amount of 0.125% convertible senior notes due 2025. These notes have a fixed annual interest rate, so they do not give rise to financial or economic interest exposure associated with changes in interest rates. However, the fair value of fixed rate debt instruments fluctuates when interest rates change. Additionally, the fair value can be affected when the market price of our common stock fluctuates. We carry the notes at face value less an unamortized discount on our consolidated balance sheet, and we present the fair value for required disclosure purposes only.

Our exposure to risk for changes in interest rates relates primarily to any borrowings under our 2022 Credit Agreement, which has a variable rate of interest. There were no outstanding borrowings under the 2022 Credit Agreement as of December 31, 2022.

Foreign Currency Risk

Growth in our international operations will incrementally increase our exposure to foreign currency fluctuations as well as other risks typical of international operations that could impact our business, including, but not limited to, differing economic conditions, changes in political climate, differing tax structures and other regulations and restrictions. Due to the strengthening U.S. dollar, our revenue results have been negatively impacted. The strengthening U.S. dollar has the opposite effect on expenses that are denominated in foreign currencies, but only partially offsets the impact to our revenue. A hypothetical 10% strengthening or weakening in the value of the U.S. dollar relative to the foreign currencies in which our revenues and expenses are denominated would not result in a material impact to our consolidated financial statements.

Transaction Exposure

Foreign exchange rate fluctuations may adversely impact our consolidated results of operations as exchange rate fluctuations on transactions denominated in currencies other than functional currencies result in gains and losses that are reflected in our consolidated statements of income. We enter into short-term foreign currency forward contracts to offset foreign exchange gains and losses generated by the re-measurement of certain assets and liabilities recorded in non-functional currencies. Changes in the fair value of these derivatives, as well as re-measurement gains and losses, are recognized in our consolidated statements of income within other income (expense), net. Foreign currency transaction gains and losses from these forward contracts were determined to be immaterial during the years ended December 31, 2022, 2021 and 2020. We do not enter into derivative financial instruments for trading or speculative purposes.

Translation Exposure

To the extent the U.S. dollar weakens against foreign currencies, the translation of these foreign currency-denominated transactions will result in increased revenue and operating expenses. Conversely, our revenue and operating expenses will decrease when the U.S. dollar strengthens against foreign currencies.

Foreign exchange rate fluctuations may also adversely impact our consolidated financial condition as the assets and liabilities of our foreign operations are translated into U.S. dollars in preparing our consolidated balance sheet. These gains or losses are recorded as a component of accumulated other comprehensive loss within stockholders' equity.

46

Credit Risk

Concentrations of credit risk with respect to accounts receivable are limited to certain customers to which we make substantial sales. Our customer base consists of a large number of geographically dispersed customers diversified across numerous industries. We believe that our accounts receivable credit risk exposure is limited. As of December 31, 2022 and 2021, there was one customer with an accounts receivable balance greater than 10% of our accounts receivable. We believe that at December 31, 2022, the concentration of credit risk related to accounts receivable was insignificant.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Akamai Technologies, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Akamai Technologies, Inc. and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of income, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO because a material weakness in internal control over financial reporting existed as of that date related to the Company not designing and maintaining effective controls over the adoption of new accounting standards related to income taxes.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness referred to above is described in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A. We considered this material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the December 31, 2022 consolidated financial statements, and our opinion regarding the effectiveness of the Company’s internal control over financial reporting does not affect our opinion on those consolidated financial statements.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for convertible instruments in 2022.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in management's report referred to above. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based

48

on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

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

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

Critical Audit Matters

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

Valuation of Customer-Related Intangible Assets and Completed Technologies Intangible Assets - Acquisition of Linode Limited Liability Company

As described in Notes 2 and 8 to the consolidated financial statements, in March 2022, the Company acquired Linode Limited Liability Company (“Linode”) for $898.5 million in cash, which resulted in customer-related intangible assets of $84.2 million and completed technologies intangible assets of $70.9 million being recorded. Management applied the multi-period excess earnings method under the income approach to estimate the fair value of the customer-related intangible assets acquired and the relief-from-royalty method to estimate the fair value of the completed technologies intangible assets acquired. Significant judgment is used by management in estimating the fair values of acquired intangible assets, which involved significant estimates and assumptions with respect to forecasted revenue growth rates, forecasted cost of sales, operating expenses, contributory asset charges and the discount rate.

The principal considerations for our determination that performing procedures relating to the valuation of customer-related intangible assets and completed technologies intangible assets acquired in connection with the Linode acquisition is a critical audit matter are (i) the significant judgment by management when determining the fair value of the customer-related intangible assets and completed technologies intangible assets acquired; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to forecasted revenue growth rates and the discount rate for the completed technologies intangible assets and forecasted cost of sales, operating expenses, contributory asset charges and the discount rate for the customer-related intangible assets; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the acquisition accounting, including controls over management’s valuation of the customer-related intangible assets and completed technologies intangible assets and controls over the development of significant assumptions related to forecasted cost of sales, operating expenses, contributory asset charges and the discount rate for the customer-related intangible assets and forecasted revenue growth rates and the discount rate for the completed technologies intangible assets. These procedures also included, among others, (i) reading the purchase agreement; (ii) testing management’s process for determining the fair value of the customer-related intangible assets and completed technologies intangible assets; (iii) evaluating the appropriateness of the multi-period excess earnings method under the income approach for the customer-related intangibles assets and the relief-from-royalty method for the completed technologies intangible assets; (iv) testing the completeness and accuracy of the underlying

49

data used in the methods; and (v) evaluating the reasonableness of the significant assumptions used by management related to forecasted cost of sales, operating expenses, contributory asset charges and the discount rate for the customer-related intangible assets and forecasted revenue growth rates and the discount rate for the completed technologies intangible assets. Evaluating management’s significant assumptions related to forecasted cost of sales, operating expenses and contributory asset charges for the customer-related intangible assets and forecasted revenue growth rates for the completed technologies intangible assets involved evaluating whether the significant assumptions used by management were reasonable considering (i) the current and past performance of Linode; (ii) consistency with external market and industry data; and (iii) whether these significant assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of the Company’s multi-period excess earnings method under the income approach, relief-from-royalty method and the reasonableness of the discount rate assumptions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business and Basis of Presentation

Akamai Technologies, Inc. (the “Company”) provides solutions to power and protect life online. Its massively distributed edge and cloud platform comprises more than 4,100 locations across more than 130 countries. The Company was incorporated in Delaware in 1998 and is headquartered in Cambridge, Massachusetts. The Company is currently organized and operates as one reportable and operating segment.

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in the accompanying consolidated financial statements.

2. Summary of Significant Accounting Policies

Use of Estimates

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ materially from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these financial statements include, but are not limited to, those related to revenue, accounts receivable and related reserves, valuation and impairment of investments and marketable securities, valuation and useful lives of acquired intangible assets, useful lives and realizability of long-lived assets, capitalized internal-use software development costs, income tax reserves and accounting for stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the date of the change in estimate.

Cash, Cash Equivalents and Marketable Securities

Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase. Marketable securities consist of corporate, government and other securities. Securities having remaining maturities of less than one year from the date of the balance sheet are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets.

The Company classifies its fixed income securities with readily determinable market values as available-for-sale. These investments are classified as marketable securities on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature and reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of income. Gains and losses on investments are calculated on the basis of specific identification.

Marketable securities are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health and business outlook of the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends; and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Assessing the above factors involves inherent uncertainty. Write-downs, if recorded, could be materially different from the actual market performance of marketable securities in the Company’s portfolio if, among other things, relevant information related to the marketable securities was not publicly available or other factors not considered by the Company would have been relevant to the determination of impairment.

58

Accounts Receivable and Related Reserves

The Company’s accounts receivable balance includes unbilled amounts that represent revenue recorded for customers that are typically billed monthly in arrears. The Company records reserves against its accounts receivable balance which primarily consists of allowances for current expected credit losses. Increases and decreases in the allowance for current expected credit losses are included as a component of general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses has been developed using historical loss rates for the previous twelve months as well as expectations about the future where the Company has been able to develop forecasts to support its estimates. In addition, the allowance considers outstanding balances on a customer-specific, account-by-account basis. The Company assesses collectibility based upon a review of customer receivables from prior sales with collection issues where the Company no longer believes that the customer has the ability to pay for services previously provided. The Company also performs ongoing credit evaluations of its customers. If such an evaluation indicates that payment is no longer reasonably assured for services provided, any future services provided to that customer will result in the creation of a cash-basis reserve until the Company receives consistent payments. The Company does not have any off-balance sheet credit exposure related to its customers.

Incremental Costs to Obtain a Contract with a Customer

The Company capitalizes incremental costs associated with obtaining customer contracts, specifically certain commission and incentive payments. The Company pays commissions and incentives up-front based on contract value upon signing a new arrangement with a customer and upon renewal and upgrades of existing contracts with customers if the renewal and upgrades result in an incremental increase in contract value. To the extent commissions and incentives are earned, the expenses, including estimated payroll taxes, are deferred on the Company's consolidated balance sheet and amortized over the expected life of the customer arrangement on a straight-line basis. Based on the nature of the Company's unique technology and services, and the rate at which the Company continually enhances and updates its technology, the expected life of the customer arrangement is determined to be approximately three years. Additionally, the Company may pay commissions and incentives based upon contract value, rather than incremental increase in contract value, to certain sales groups within the Company. For these commission arrangements, the Company amortizes capitalized costs for contract renewals over an average renewal contract period of 16 months. The Company also incurs commission expense on an ongoing basis based upon revenue recognized. In these cases, no incremental costs are deferred, as the commissions are earned and expensed in the same period for which the associated revenue is recognized.

Amortization of the costs is primarily included in sales and marketing expense in the consolidated statements of income. The current portion of deferred commission and incentive payments is included in prepaid expenses and other current assets, and the long-term portion is included in other assets on the Company's consolidated balance sheets.

Concentrations of Credit Risk

The amounts reflected in the consolidated balance sheets for accounts receivable, other current assets, accounts payable, accrued liabilities and other current liabilities approximate fair values due to their short-term maturities. The Company maintains the majority of its cash, cash equivalents and marketable securities with major financial institutions that the Company believes to be of high credit standing. The Company believes that, as of December 31, 2022, its concentration of credit risk related to cash equivalents and marketable securities was not significant.

Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which the Company makes substantial sales. The Company’s customer base consists of a large number of geographically-dispersed customers diversified across several industries. To reduce risk, the Company routinely assesses the financial strength of its customers. Based on such assessments, the Company believes that its accounts receivable credit risk exposure is limited. For the years ended December 31, 2022, 2021 and 2020, no customer accounted for more than 10% of total revenue. As of December 31, 2022 and 2021, there was one customer with an accounts receivable balance greater than 10% of total accounts receivable. The Company believes that, as of December 31, 2022 and 2021, its concentration of credit risk related to accounts receivable was not significant.

Fair Value of Financial Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company has certain financial assets and liabilities recorded at fair value, principally cash equivalents and short- and long-term marketable securities that have been classified as Level 1, 2 or 3 within the fair value hierarchy. Fair

59

values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the reporting date. Fair values determined by Level 2 inputs utilize data points other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair values determined by Level 3 inputs are based on unobservable data points for the asset or liability.

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Property and equipment generally include purchases of items with a per-unit value greater than $1,000 and an estimated useful life greater than one year. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the related lease terms or their estimated useful lives.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in income from operations. Repairs and maintenance costs are expensed as incurred.

Operating Leases

The Company enters into operating leases for real estate assets related to office space and co-location assets related to space or racks at co-location facilities and related equipment for its servers and other networking equipment. The Company determines if an arrangement contains a lease at the inception of a contract by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration and the right to obtain the economic benefits from the use of the identified asset.

Upon commencement of a lease, the Company records a right-of-use asset that represents the Company’s right to use the underlying asset for the lease term and a lease liability that represents an obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Lease payments are discounted at the lease commencement date. As the Company’s leases do not provide an implicit rate, an incremental borrowing rate has been applied based on the Company's credit-adjusted risk-free rate.

The Company often enters into contracts that contain both lease and non-lease components. Real estate non-lease components include real estate taxes, insurance, maintenance, parking and other operating costs. Co-location non-lease components include utilities and other operating costs. The Company includes both lease and non-lease components of fixed costs in its lease arrangements as a single lease component. Variable costs, such as utilities based on actual usage, are not included in the measurement of right-of-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs.

The Company’s lease terms often include renewal options and, particularly in the case of co-location arrangements, may include evergreen provisions. The Company’s right-of-use assets and lease liabilities generally do not include the options to extend, or terminate, unless it is reasonably certain that the Company will exercise these options. The Company has elected to exclude leases for certain networking equipment and leases assumed through acquisitions with terms of 12 months or less from its right-of-use assets and lease liabilities on its consolidated balance sheets.

Lease expense is recognized on a straight-line basis over the expected lease term.

Equity Method Investments

The Company accounts for equity investments in which it has significant influence, but not a controlling financial interest, using the equity method of accounting. Under the equity method of accounting, investments are initially recorded at cost, less impairment, and subsequently adjusted to recognize the Company’s share of earnings or losses.

In February 2019, the Company and Mitsubishi UFJ Financial Group ("MUFG") announced the establishment of a joint venture, the Global Open Network, Inc. ("GO-NET"), and their plans to offer a new blockchain-based online payment network. The Company's 20% stake in GO-NET was accounted for using the equity method.

During the first quarter of 2022, MUFG, the majority owner of GO-NET, announced its intention to suspend the operations of GO-NET and to eventually liquidate it. As a result of MUFG's intention to suspend operations, the Company impaired its remaining investment of $7.5 million. The Company recorded a loss of $14.0 million during the year ended December 31,

60

2021, which reflects its share of the losses incurred by GO-NET during that year. During the year ended December 31, 2020, the Company recorded a loss of $13.1 million, which included an $11.0 million impairment to reduce the Company's investment to its fair value due to a modified business plan and continued negative projected cash flows. The valuation technique used to measure fair value of the Company's equity method investment in GO-NET was primarily an adjusted net asset value model based on labor costs and the amount of time required to develop a similar technology for use in the planned payment processing service.

Subsequent to the establishment of the joint venture, the Company recorded revenue of $4.0 million, $10.1 million, and $11.1 million for the years ended December 31, 2022, 2021 and 2020, respectively, for services provided to GO-NET. The Company no longer provided services after June 30, 2022 due to the intention to suspend operations and to eventually liquidate it.

Goodwill, Acquired Intangible Assets and Long-Lived Assets

Goodwill is the amount by which the cost of acquired net assets in a business combination exceeds the fair value of the net identifiable assets on the date of purchase and is carried at its historical cost. The Company tests goodwill for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company performs its impairment test of goodwill as of December 31 each year. As of December 31, 2022, 2021 and 2020, the Company concluded that it has one reporting unit and that its chief operating decision maker is its chief executive officer and the executive management team. The Company has assigned the entire balance of goodwill to one reporting unit. The fair value of the reporting unit was based on the Company's market capitalization as of each of December 31, 2022 and 2021, and it was substantially in excess of the carrying value of the reporting unit at each date. The fair value of the Company's reporting unit was determined by the Company's enterprise value as of the years ended December 31, 2022, 2021 and 2020.

Acquired intangible assets consist of completed technologies, customer relationships, trademarks and trade names, non-compete agreements and acquired license rights. Acquired intangible assets, other than goodwill, are amortized over their estimated useful lives based upon the estimated economic value derived from the related intangible asset. Significant judgment is used in determining fair values of acquired intangibles assets and their estimated useful lives. Fair value and useful life determinations may be based on, among other factors, estimates of future expected cash flows, royalty cost savings and appropriate discount rates used in calculating present values.

Long-lived assets, including property and equipment, operating lease right-of-use assets and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances, such as service discontinuance, technological obsolescence, significant decreases in the Company’s market capitalization, facility closures or work-force reductions indicate that the carrying amount of the long-lived asset may not be recoverable. When such events occur, the Company compares the carrying amount of the asset to the undiscounted expected future cash flows related to the asset. If this comparison indicates that an impairment is present, the amount of the impairment is calculated as the difference between the carrying amount and the fair value of the asset.

Contract Liabilities

Contract liabilities primarily represent payments received from customers for which the related performance obligations have not yet been satisfied. These balances consist of the unearned portion of monthly service fees and integration fees and prepayments made by customers for future periods. The current and long-term portions of the Company's contract liabilities are included in deferred revenue in the respective sections of the Company's consolidated balance sheets.

Revenue Recognition

The Company primarily derives revenue from the sale of services to customers executing contracts having terms of one year or longer. Services included in the Company's contracts consist of its core services – the delivery of content, applications and software over the internet – as well as security and cloud computing solutions and professional services. Revenue is recognized upon transfer of control of promised services in an amount that reflects the consideration the Company expects to receive in exchange for those services.

The Company enters into contracts that may include various combinations of these services, which are generally capable of being distinct and accounted for as separate performance obligations. These contracts generally commit the customer to a minimum of monthly, quarterly or annual levels of usage and specify the rate at which the customer must pay for actual usage above the stated minimum. Based on the typical structure of the Company's contracts, which are generally for monthly

61

recurring services that are essentially the same over time and have the same pattern of transfer to the customer, most performance obligations represent a promise to deliver a series of distinct services over time.

The Company's contracts with customers sometimes include promises to deliver multiple services to a customer. Determining whether services are distinct performance obligations often requires the exercise of judgment by management. For example, advanced features that enhance a service and are highly interrelated are generally not considered distinct; rather, they are combined with the service they relate to into one performance obligation. Different determinations related to combining services into performance obligations could result in differences in the timing and amount of revenue recognized in a period.

Generally, the transaction price in a contract is equal to the committed price stated in the contract, less any discounts or rebates. The Company's typical contracts qualify for series accounting, and the pricing terms generally do not require estimation of the transaction price beyond the reporting period. As a result, any incremental fees generated as a result of usage or “bursting” over committed contract levels are recorded in the period to which the services relate. The amount of consideration recognized for usage above contract minimums is limited to the amount the Company expects to be entitled to receive in exchange for providing the services. Once the transaction price has been determined, the Company allocates such price among all performance obligations in the contract on a relative standalone selling price (“SSP”) basis.

Determination of SSP requires the exercise of judgment by management. SSP is based on observable inputs such as the price the Company charges for the service when sold separately or the discounted list price per management’s approved price list. In cases where services are not sold separately or price list rates are not available, a cost-plus-margin approach or adjusted market approach is used to determine SSP.

Most content delivery and security services represent stand-ready obligations that are satisfied over time as the customer simultaneously receives and consumes the benefits provided by the Company. Accordingly, revenue for those services is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any bursting over given commitments is recognized in the period in which the traffic was served. For services that involve traffic consumption, revenue is recognized in an amount that reflects the level of traffic served to a customer in a given period. For custom arrangements, other methods may be used as a measure of progress towards satisfying the performance obligations.

Some of the Company's contracts are satisfied at a point in time, such as one-time professional services, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at the point in time of delivery or satisfaction of the performance obligation.

From time to time, the Company enters into contracts to sell its services or license its technology to unrelated enterprises at or about the same time that it enters into contracts to purchase products or services from the same enterprises. Consideration payable to a customer is reviewed as part of the transaction price. If the payment to the customer does not represent payment for a distinct service, revenue is recognized only up to the net amount of consideration after customer payment obligations are considered. The Company may also resell the licenses or services of third parties. If the Company is acting as an agent in an arrangement with a customer to provide third party services, the transaction price reflects only the net amount to which the Company will be entitled, after accounting for payments made to the third party responsible for satisfying the performance obligation.

Cost of Revenue

Cost of revenue consists primarily of fees paid to network providers for bandwidth and to third-party network data centers for housing servers, also known as co-location costs. Cost of revenue also includes employee costs for services delivery and network operation, build-out and support of the Company's network; network storage costs; cost of software licenses; depreciation of network equipment used to deliver the Company’s services; amortization of network-related internal-use software; and costs for the production of live events streamed by the Company for customers. The Company enters into contracts for bandwidth with third-party network providers with terms typically ranging from several months to five years. These contracts generally commit the Company to pay minimum monthly fees plus additional fees for bandwidth usage above the committed level. In some circumstances, internet service providers (“ISPs”) make rack space available for the Company to locate its servers and provide access to their bandwidth at a discount or no cost. Although the Company does not provide any goods or services to the ISPs or the ISPs’ customers under these arrangements, the ISPs and their customers indirectly benefit by accessing content through a local Company server, resulting in better content delivery. The Company records the cost of these vendor relationships at their negotiated transaction price, which is either at a discount or no cost.

Research and Development Costs and Capitalized Internal-Use Software

Research and development costs consist primarily of payroll and related personnel costs for the design, development, deployment, testing and enhancement of the Company’s services and network. Costs incurred in the development of the Company’s services are expensed as incurred, except certain internal-use software development costs eligible for capitalization.

Capitalized costs include external consulting fees, payroll and payroll-related costs and stock-based compensation for employees in the Company’s development and information technology groups who are directly associated with, and who devote time to, the Company’s internal-use software projects. Capitalization begins when the planning stage is complete and the Company commits resources to the software project; capitalization continues during the application development stage. Capitalization ceases when the software has been tested and is ready for its intended use. Costs incurred during the planning, training and post-implementation stages of the software development life-cycle are expensed as incurred. The Company amortizes completed internal-use software that is used on its network to cost of revenue over its estimated useful life.

Accounting for Stock-Based Compensation

The Company recognizes compensation costs for all stock-based payment awards made to employees based upon the awards’ grant-date fair value. The stock-based payment awards include stock options, restricted stock, restricted stock units, deferred stock units and employee stock purchases related to the Company’s employee stock purchase plan.

For stock options, the Company has selected the Black-Scholes option-pricing model to determine the fair value of stock option awards. For stock awards with market-based vesting conditions, the Company uses a Monte Carlo simulation to determine the fair value of the award. For stock options, restricted stock units and deferred stock units that contain only a service-based vesting feature, the Company recognizes compensation cost on a straight-line basis over the award's vesting period. For awards with a performance condition-based vesting feature, the Company recognizes compensation cost on a graded-vesting basis over the award's expected vesting period, commencing when achievement of the performance condition is deemed probable. In addition, for awards that vest and become exercisable only upon achievement of specified performance conditions, the Company makes judgments and estimates each quarter about the probability that such performance conditions will be met or achieved. Any changes to those estimates that the Company makes from time to time may have a significant impact on the stock-based compensation expense recorded and could materially impact the Company’s results of operations.

Foreign Currency Translation and Forward Currency Contracts

The assets and liabilities of the Company's subsidiaries are translated at the applicable exchange rate as of the balance sheet date, and revenue and expenses are translated at an average rate over the period. Resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss, a separate component of stockholders’ equity. Gains and losses on inter-company and other non-functional currency transactions are recorded in other income (expense), net.

The Company enters into short-term foreign currency forward contracts to offset foreign exchange gains and losses generated by the re-measurement of certain assets and liabilities recorded in non-functional currencies. Changes in the fair value of these derivatives, as well as re-measurement gains and losses, are recognized in current earnings in other income (expense), net. As of December 31, 2022 and 2021, the fair value of the forward currency contracts and the underlying gains and losses for the years ended December 31, 2022, 2021 and 2020 were immaterial.

The Company's foreign currency forward contracts may be exposed to credit risk to the extent that its counterparties are unable to meet the terms of the agreements. The Company seeks to minimize counterparty credit (or repayment) risk by entering into transactions only with major financial institutions of investment grade credit rating.

Income Taxes

The Company's provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated as the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse or the carryforwards are expected to be realized.

63

    The Company currently has net deferred tax assets consisting of net operating loss (“NOL”) carryforwards, tax credit carryforwards and deductible temporary differences. Management periodically weighs the positive and negative evidence to determine if it is more-likely-than-not that some or all of the deferred tax assets will be realized.

    The Company has recorded certain tax reserves to address potential exposures involving its income tax positions. These potential tax liabilities result from the varying application of statutes, rules, regulations and interpretations by different taxing jurisdictions. The Company's estimate of the value of its tax reserves contains assumptions based on past experiences and judgments about the interpretation of statutes, rules and regulations by taxing jurisdictions. It is possible that the costs of the ultimate tax liability or benefit from these matters may be more or less than the amount the Company estimated.

    Uncertainty in income taxes is recognized in the Company's consolidated financial statements using a two-step process. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained based on technical merit, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement.

Newly-Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board ("FASB") issued guidance that was expected to reduce complexity and improve comparability of financial reporting associated with accounting for convertible instruments and contracts in an entity’s own equity. The Company adopted this guidance on January 1, 2022 on a modified retrospective basis.

The convertible senior notes included on the Company's consolidated balance sheet more closely reflect the principal amounts. Prior to the adoption of this guidance, the Company separated its convertible senior notes into a liability and an equity component. The equity portion is now eliminated. The cumulative effect of the changes was an increase to convertible senior notes of $304.7 million, an increase to deferred income tax liabilities of $0.7 million, an increase to deferred income tax assets of $77.7 million, a decrease to property and equipment of $7.7 million and a decrease to additional paid-in capital of $375.4 million on the consolidated balance sheet. The net effect of these adjustments was recorded as an increase to retained earnings as of January 1, 2022.

Additionally, the new guidance eliminates the use of the treasury stock method for convertible instruments that can be settled in whole or in part with equity, when calculating diluted earnings per share. Instead, it requires application of the if-converted method. Under that method, diluted earnings per share would generally be calculated assuming that all the convertible senior notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. The application of the if-converted method reduces the Company’s reported diluted earnings per share after the adoption date. However, in December 2021, the Company made an irrevocable election to settle the principal portion of the convertible senior notes with cash. Accordingly, the if-converted method is only impacted by any potential shares to be delivered for the amount in excess of the principal portion. The changes to the diluted earnings per share guidance did not materially impact the Company's results of operations.

With the elimination of the debt discount created by the equity component, amortization of the debt discount is eliminated, which decreases interest expense, and therefore increases net income and earnings per share, from the period of adoption. This had the effect of increasing basic and diluted earnings per share for the year ended 2022 by $0.32.

The Company offers certain eligible employees the ability to participate in a non-qualified deferred compensation plan. The mutual funds held by the Company that are associated with this plan are classified as restricted trading securities. These securities are not included in the available-for-sale securities table above but are included in marketable securities in the consolidated balance sheets.

Unrealized gains and unrealized temporary losses on investments classified as available-for-sale are included within accumulated other comprehensive loss in the consolidated balance sheets. Upon realization, those amounts are reclassified from accumulated other comprehensive loss to interest and marketable securities income, net in the consolidated statements of income. As of December 31, 2022, the Company held for investment corporate bonds with a fair value of $835.4 million, which are classified as available-for-sale marketable securities and have been in a continuous unrealized loss position for more than 12 months. The unrealized losses related to these corporate bonds were $31.3 million and are included in accumulated other comprehensive loss as of December 31, 2022. The unrealized losses are attributable to changes in interest rates. Based on the evaluation of available evidence, the Company does not believe any unrealized losses represent other than temporary impairments.

	$	1,752,830	$	132,442	$	1,620,388

As of December 31, 2022 and 2021, the Company grouped money market and mutual funds using a Level 1 valuation because market prices for such investments are readily available in active markets. As of December 31, 2022 and 2021, the Company grouped time deposits, commercial paper, U.S. government agency obligations and corporate bonds using a Level 2 valuation because quoted prices for similar assets in active markets (or identical assets in an inactive market) are available. The Company did not have any transfers of assets or liabilities between Level 1 or Level 2 of the fair value measurement hierarchy during the years ended December 31, 2022 and 2021.

When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. When available, the Company uses quoted market prices to measure fair value. The valuation technique used to measure fair value for the Company's Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about the assumptions market participants would use to estimate the fair value of a financial instrument.

Contractual maturities of the Company’s available-for-sale marketable securities held as of December 31, 2022 and 2021 were as follows (in thousands):

Pro forma results of operations for the acquisitions completed in the years ended December 31, 2022, 2021 and 2020 have not been presented because the effects of the acquisitions, individually and in the aggregate, were not material to the Company's consolidated financial results.

2022 Acquisition

Linode

In March 2022, the Company acquired all the outstanding equity interests of Linode Limited Liability Company ("Linode") for $898.5 million in cash. Linode is an infrastructure-as-a-service platform provider that allows for developer-friendly cloud computing capabilities. The acquisition is intended to enhance the Company’s computing services by enabling it to create a unique cloud platform to build, run and secure applications from the cloud to the edge. Revenue attributable to Linode since the date of the acquisition, included in the Company's consolidated statements of income, for 2022 was $103.5 million. Earnings included in the Company's consolidated statements of income since the date of the acquisition are not material.

As of December 31, 2022, the purchase price allocation was substantially complete except for the finalization of certain income tax matters. Measurement period adjustments to goodwill recognized during 2022 related to the acquisition of Linode were $28.9 million and primarily related to property and equipment and intangible asset adjustments. These measurement period adjustments did not have a material effect on the Company's results of operations.

The value of the goodwill can be attributed to a number of business factors, including a trained technical workforce and cost synergies expected to be realized. The Company expects that all of the goodwill related to the acquisition of Linode will be deductible for tax purposes.

Identified intangible assets acquired and their respective weighted average useful lives were as follows (in thousands, except years):

	Gross Carrying Amount		Weighted Average Useful Life (in years)
Customer-related intangible assets	$	84,200	16.8
Completed technologies	70,900		5.8
Acquired license rights	34,320		15.0
Trademarks and trade name	6,600		8.8
Total	$	196,020

The Company applied the relief-from-royalty method to estimate the fair values of the completed technologies and trademarks and the multi-period excess earnings method under the income approach to estimate the fair values of the customer-related acquired intangible assets. The Company applied significant judgment in estimating the fair values of the acquired intangible assets, which involved significant estimates and assumptions with respect to forecasted revenue growth rates, cost of revenue, operating expenses, contributory asset charges and discount rates. The Company used readily available market data to estimate the fair values of the acquired license rights. The total weighted average amortization period for the intangible assets acquired from Linode is 12.2 years. The intangible assets are being amortized based upon the pattern in which the economic benefits of the intangible assets are being utilized.

11. Debt

Convertible Senior Notes – Due 2027

In August 2019, the Company issued $1,150.0 million in par value of convertible senior notes due 2027 (the "2027 Notes"). The 2027 Notes are senior unsecured obligations of the Company, bear regular interest of 0.375%, payable semi-annually in arrears on March 1 and September 1 of each year, and mature on September 1, 2027, unless repurchased or converted in accordance with their terms prior to maturity.

Each $1,000 principal amount of the notes will be convertible into 8.6073 shares of the Company's common stock, which is equivalent to a conversion price of approximately $116.18 per share, subject to adjustments in certain events. At their option, holders may convert their 2027 Notes prior to the close of business on the business day immediately preceding May 1, 2027, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ended December 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or

•upon the occurrence of specified corporate events.

74

On or after May 1, 2027, holders may convert all or any portion of their 2027 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

In December 2021, the Company made an irrevocable election to settle the principal amount of the 2027 Notes only in cash. Accordingly, upon conversion, the Company will pay the principal amount in cash and will pay, or deliver, as the case may be, any amount in excess of the principal amount in cash, shares of common stock or a combination of cash and shares of the Company stock, at the Company's election. Prior to this election, upon conversion, the Company, could have elected to deliver to holders cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock for the principal amount.

Prior to January 1, 2022, in accounting for the issuance of the 2027 Notes, the Company separated the 2027 Notes into liability and equity components. The carrying cost of the liability component was calculated by measuring the fair value of a similar debt obligation that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2027 Notes. The difference between the principal amount of the 2027 Notes and the proceeds allocated to the liability component (“debt discount”) is amortized to interest expense using the effective interest method over the term of the 2027 Notes. The equity component is recorded in additional paid-in capital in the consolidated balance sheet to meet the conditions for equity classification. On January 1, 2022, the Company adopted the new guidance for accounting for convertible instruments, which eliminated the equity component. Refer to Note 2 to the consolidated financial statements included elsewhere in this report for details on the new guidance for accounting for convertible instruments.

Initially, the Company allocated the total transaction costs incurred to the liability and equity components based on their relative values. However, subsequent to the adoption of the new guidance for accounting for convertible instruments, all transaction costs are presented as a reduction to the 2027 Notes. Prior to January 1, 2022, transaction costs attributable to the liability component were being amortized to interest expense over the term of the 2027 Notes, and subsequent to the adoption of the new guidance, all transaction costs are being amortized to interest expense over the term of the 2027 Notes.

The 2027 Notes consisted of the following components as of December 31, 2022 and 2021 (in thousands):

	December 31, 2022		December 31, 2021
Liability component:
Principal	$	1,150,000	$	1,150,000
Less: debt discount and issuance costs, net of amortization	(8,707)		(169,030)
Net carrying amount	$	1,141,293	$	980,970
Equity component:	$	—	$	220,529

The estimated fair value of the 2027 Notes at December 31, 2022 and 2021 was $1,111.0 million and $1,359.3 million, respectively. The fair value was determined based on the quoted price of the 2027 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy. Based on the closing price of the Company's common stock of $84.30 on December 31, 2022, the value of the 2027 Notes if converted to common stock was less than the principal amount of $1,150.0 million.

The Company used $100.0 million of the proceeds from the offering to repurchase shares of its common stock, concurrent with the issuance of the 2027 Notes. The repurchase was made in accordance with a share repurchase program previously approved by the board of directors. Additionally, $127.1 million of the proceeds was used for the net cost of the convertible note hedge and warrant transactions. The remaining net proceeds are intended to be used for share repurchases, working capital and general corporate purposes, including potential acquisitions and other strategic transactions.

75

Note Hedge

To minimize the impact of potential dilution upon conversion of the 2027 Notes, the Company entered into convertible note hedge transactions with respect to its common stock in August 2019. The Company paid $312.2 million for the note hedge transactions. The note hedge transactions cover approximately 9.9 million shares of the Company’s common stock at a strike price that corresponds to the initial conversion price of the 2027 Notes, also subject to adjustment, and are exercisable upon conversion of the 2027 Notes. The Company determined that the note hedge meets the definition of a derivative and is classified in stockholders’ equity, as the note hedge is indexed to the Company's common stock, and the Company, at its election, may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock. The Company recorded the purchase of the hedge as a decrease to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the note hedge in its consolidated financial statements.

Warrants

Separately, in August 2019, the Company entered into warrant transactions, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, up to 9.9 million shares of the Company’s common stock at a strike price of approximately $178.74 per share. The Company received aggregate proceeds of $185.2 million from the sale of the warrants. The convertible note hedge and warrant transactions will generally have the effect of increasing the conversion price of the 2027 Notes to approximately $178.74 per share. The Company determined that the warrants meet the definition of a derivative and are classified in stockholders’ equity, as the warrants are indexed to the Company's common stock, and the Company, at its election, may pay or deliver to holders cash or shares of the Company's common stock. The Company recorded the proceeds from issuance of the warrants as an increase to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the warrants in its consolidated financial statements.

Convertible Senior Notes – Due 2025

In May 2018, the Company issued $1,150.0 million in par value of convertible senior notes due 2025 (the "2025 Notes"). The 2025 Notes are senior unsecured obligations of the Company, bear regular interest of 0.125%, payable semi-annually on May 1 and November 1 of each year, and mature on May 1, 2025, unless repurchased or converted prior to maturity.

Each $1,000 principal amount of the notes will be convertible into 10.5150 shares of the Company's common stock, which is equivalent to a conversion price of approximately $95.10 per share, subject to adjustments in certain events. At their option, holders may convert their 2025 Notes prior to the close of business on the business day immediately preceding January 1, 2025, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ended June 30, 2018 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or

•upon the occurrence of specified corporate events.

On or after January 1, 2025, holders may convert all or any portion of their 2025 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date, regardless of the foregoing circumstances.

In December 2021, the Company made an irrevocable election to settle the principal amount of the 2025 Notes only in cash. Accordingly, upon conversion, the Company will pay the principal amount in cash and will pay, or deliver, as the case may be, any amount in excess of the principal amount in cash, shares of common stock or a combination of cash and shares of the Company stock, at the Company's election. Prior to this election, upon conversion, the Company, could have elected to deliver to holders cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock for the principal amount.

Revolving Credit Facility

In May 2018, the Company entered into a $500.0 million five-year, revolving credit agreement (the “2018 Credit Agreement”). Borrowings under the 2018 Credit Agreement bore interest, at the Company's option, at a base rate plus a spread of 0.00% to 0.25% or an adjusted LIBOR rate plus a spread of 0.875% to 1.25%, in each case with such spread being determined based on the Company's consolidated leverage ratio specified in the 2018 Credit Agreement. Regardless of what amounts, if any, outstanding under the 2018 Credit Agreement, the Company was also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.075% to 0.15%, with such rate being based on the Company's consolidated leverage ratio specified in the 2018 Credit Agreement.

In November 2022, the Company entered into a $500.0 million five-year, revolving credit agreement (the “2022 Credit Agreement”). The 2022 Credit Agreement replaces the 2018 Credit Agreement. Borrowings under the 2022 Credit Agreement may be used to finance working capital needs and for general corporate purposes. The 2022 Credit Agreement provides for an initial $500.0 million in revolving loans. Under specified circumstances, the facility can be increased to up to $1.0 billion in aggregate principal amount. The 2022 Credit Agreement expires, and any amounts outstanding thereunder will become due and payable, on November 22, 2027, subject to up to two one-year extensions at the Company's request and with the consent of the lenders party thereto.

Borrowings under the 2022 Credit Agreement bear interest, at the Company's option, and subject to a credit spread adjustment, at a term benchmark rate plus a spread of 0.75% to 1.125%, a reference rate plus a spread of 0.75% to 1.125%, or a base rate plus a spread of 0.00% to 0.125%, in each case with such spread being determined based on the Company's consolidated leverage ratio specified in the 2022 Credit Agreement.

The 2022 Credit Agreement contains customary representations and warranties, affirmative and negative covenants and events of default. The negative covenants include restrictions on subsidiary indebtedness, liens and fundamental changes. These covenants are subject to a number of important exceptions and qualifications. The principal financial covenant requires a maximum consolidated leverage ratio. There were no outstanding borrowings under the 2022 Credit Agreement as of December 31, 2022.

Legal Matters

The Company is party to various litigation matters that management considers routine and incidental to its business. Management does not expect the results of any of these routine actions to have a material effect on the Company’s business, results of operations, financial condition or cash flows.

80

Indemnification

The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company agrees to indemnify, hold harmless and reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company's business partners, vendors or customers, in connection with its provision of its services. Generally, these obligations are limited to claims relating to infringement of a patent, copyright or other intellectual property right or the Company’s negligence, willful misconduct or violation of law. Subject to applicable statutes of limitation, the term of each of these indemnification agreements is generally perpetual from the time of execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company carries insurance that covers certain third-party claims relating to its services and activities and that could limit the Company’s exposure in that respect.

The Company has agreed to indemnify each of its officers and directors, or employees who serve as officers or directors of its subsidiaries at management's request, during his or her lifetime for certain events or occurrences that happen by reason of the fact that the officer or director is or was or has agreed to serve as an officer or director of the Company. The Company has director and officer insurance policies that may limit its exposure and may enable the Company to recover a portion of certain future amounts paid.

To date, the Company has not encountered material costs as a result of such indemnification obligations and has not accrued any related liabilities in its financial statements. In assessing whether to establish an accrual, the Company considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

14. Stockholders’ Equity

Stock Repurchase Program

In November 2018, the board of directors authorized a $1.1 billion repurchase program through December 2021. In October 2021, the board of directors authorized a new $1.8 billion share repurchase program, effective January 2022 through December 2024. The Company's goals for the share repurchase programs are to offset the dilution created by its employee equity compensation programs over time and provide the flexibility to return capital to shareholders as business and market conditions warrant, while still preserving its ability to pursue other strategic opportunities.

During the years ended December 31, 2022, 2021 and 2020, the Company repurchased 6.4 million, 4.7 million and 2.0 million shares, respectively, of its common stock for $608.0 million, $522.3 million and $193.6 million, respectively, pursuant to the repurchase programs described above. As of December 31, 2022, the Company had $1.2 billion available for future purchases of shares under the current repurchase program.

The board of directors authorized the retirement of all the outstanding shares of its treasury stock as of each of December 31, 2022, 2021 and 2020. The retired shares were returned to the number of authorized but unissued shares of the Company's common stock, and the retirement was recorded to additional paid-in capital.

Balance as of December 31, 2022	$	(116,474)	$	(23,858)	$	(140,332)

Amounts reclassified from accumulated other comprehensive loss to net income were immaterial for the years ended December 31, 2022 and 2021.

16. Revenue from Contracts with Customers

The Company sells its services through a sales force located both domestically and abroad. Revenue derived from operations outside of the U.S. is determined based on the country in which the sale originated. Other than the U.S., no single country accounted for 10% or more of the Company’s total revenue for any reported period. Revenue by geography included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands):

	2022		2021		2020
U.S.	$	1,902,051	$	1,837,508	$	1,777,435
International	1,714,603		1,623,715		1,420,714
Total revenue	$	3,616,654	$	3,461,223	$	3,198,149

The Company reports its revenue in three solution categories: security, delivery and compute. Prior to January 1, 2022, revenue by solution was reported by product group: Security Technology Group and Edge Technology Group. Revenue from security solutions was previously presented as Security Technology Group revenue and revenue from delivery and compute solutions was previously presented as Edge Technology Group revenue. The periods presented prior to January 1, 2022 have been revised to reflect this new presentation. Security includes solutions that are designed to protect business online by keeping infrastructure, websites, applications and users safe. Delivery includes solutions that are designed to enable business online, including media delivery and web performance. Compute includes cloud computing, edge applications, cloud optimization and storage. Revenue by solution category included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands):

	2022		2021		2020
Security	$	1,541,941	$	1,334,836	$	1,061,622
Delivery	1,669,257		1,873,243		1,929,810
Compute	405,456		253,144		206,717
Total revenue	$	3,616,654	$	3,461,223	$	3,198,149

Most security, delivery and compute services represent obligations that are satisfied over time as the customer simultaneously receives and consumes the services provided by the Company. Accordingly, the majority of the Company's revenue is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any usage over a given commitment is recognized in the period in which the units are served. A small percentage of the Company's contracts are satisfied at a point in time, such as one-time professional services contracts, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at a point in time of delivery or satisfaction of the performance obligation.

82

During the years ended December 31, 2022, 2021 and 2020, the Company recognized $105.1 million, $78.8 million and $69.9 million of revenue that was included in deferred revenue as of December 31, 2021, 2020 and 2019, respectively.

As of December 31, 2022, the aggregate amount of remaining performance obligations from contracts with customers was $3.5 billion. The Company expects to recognize approximately 65% of its remaining performance obligations as revenue over the next 12 months, with the remainder recognized thereafter. Remaining performance obligations represent the amount of the transaction price under contracts with customers that are attributable to performance obligations that are unsatisfied or partially satisfied at the reporting date. This consists of future committed revenue for monthly, quarterly or annual periods within current contracts with customers, as well as deferred revenue arising from consideration invoiced in prior periods for which the related performance obligations have not been satisfied. It excludes estimates of variable consideration such as usage-based contracts with no committed contract as well as anticipated renewed contracts. Revenue recognized during the years ended December 31, 2022, 2021 and 2020, related to performance obligations satisfied in previous periods was not material.

17. Employee Benefit Plan

The Company has established a savings plan for its employees that is designed to be qualified under Section 401(k) of the Internal Revenue Code. Eligible employees are permitted to contribute to this plan through payroll deductions within statutory and plan limits. The Company contributed $18.8 million, $17.7 million and $17.5 million of cash to the savings plan for the years ended December 31, 2022, 2021 and 2020, respectively, under a matching program.

18. Stock-Based Compensation

Equity Plans

In May 2013, the Company's stockholders approved the Akamai Technologies, Inc. 2013 Stock Incentive Plan, which was amended with Company shareholder approval in each of 2015, 2017 and 2019 and was amended and restated with Company shareholder approval in each of 2021 and 2022 (as amended and restated, the "2013 Plan"). The 2013 Plan replaced the Akamai Technologies, Inc. 2009 Stock Incentive Plan (the "2009 Plan"), which in turn replaced the Akamai Technologies, Inc. 2006 Stock Incentive Plan, the Akamai Technologies, Inc. 2001 Stock Incentive Plan and the Akamai Technologies, Inc. 1998 Stock Incentive Plan (such plans, together with the 2009 Plan, the "Previous Plans"). The Company no longer issues equity awards under the Previous Plans, and they solely exist to satisfy outstanding equity awards previously granted under those plans. The 2013 Plan allows for the issuance of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards and cash-based awards for up to 26.5 million shares of common stock, subject to certain adjustments, to employees, officers, directors, consultants and advisers of the Company. Additionally, the Company may grant up to 3.8 million shares of common stock thereunder that were available for grant under the 2009 Plan immediately prior to stockholder approval of the 2013 Plan. Any shares of common stock that are currently outstanding under the Previous Plans that are terminated, canceled, surrendered or forfeited will become available to grant under the 2013 Plan. As of December 31, 2022, the Company had reserved 6.2 million shares of common stock available for future issuance of equity awards under the 2013 Plan.

The Company has assumed certain stock incentive plans and the outstanding stock incentives of companies that it has acquired (“Assumed Plans”). Stock incentive awards outstanding as of the date of acquisition under the Assumed Plans were exchanged for the Company’s stock incentive awards and adjusted to reflect the appropriate conversion ratio as specified by the applicable acquisition agreement, but are otherwise administered in accordance with the terms of the Assumed Plans. Stock incentive awards under the Assumed Plans generally vest over three years to four years, and outstanding stock options under the Assumed Plans expire ten years from the date of grant.

The 1999 Employee Stock Purchase Plan ("1999 ESPP") permits eligible employees to purchase up to 1.5 million shares each June 1 and December 1, provided that the aggregate number of shares issued shall not exceed 20.0 million. The 1999 ESPP allows participants to purchase shares of common stock at a 15% discount from the fair market value of the stock as determined on specific dates at six-month intervals. During the years ended December 31, 2022, 2021 and 2020, the Company issued 0.7 million, 0.6 million and 0.7 million shares under the 1999 ESPP, respectively, with a weighted average purchase price per share of $82.83, $92.05 and $80.71, respectively. Total cash proceeds from the purchase of shares under the 1999 ESPP in the years ended December 31, 2022, 2021 and 2020 were $56.6 million, $59.7 million and $58.4 million, respectively. As of December 31, 2022, approximately $5.8 million had been withheld from employees for future purchases under the 1999 ESPP.

Stock-Based Compensation Expense

Components of total stock-based compensation expense included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

	2022		2021		2020
Cost of revenue	$	28,354	$	27,143	$	24,829
Research and development	78,116		65,950		48,855
Sales and marketing	47,789		46,342		65,257
General and administrative	62,926		63,324		58,470
Total stock-based compensation	217,185		202,759		197,411
Provision for income taxes	(46,829)		(56,084)		(62,153)
Total stock-based compensation, net of taxes	$	170,356	$	146,675	$	135,258

In addition to the amounts of stock-based compensation reported in the table above, the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 also include stock-based compensation reflected as a component of amortization primarily consisting of capitalized internal-use software; the additional stock-based compensation was $31.3 million, $32.4 million and $29.6 million, respectively, before taxes.

The Company uses the Black-Scholes option pricing model to determine the fair value of the Company’s stock option awards. This model requires the input of subjective assumptions, including expected stock price volatility and the estimated term of each award. The estimated fair value of the Company's stock-based awards, less expected forfeitures, is amortized over the awards’ vesting period on a straight-line basis. Expected volatilities are based on the Company’s historical stock price volatility and implied volatility from traded options in its stock. The Company uses historical data to estimate the expected term of options granted within the valuation model. The risk-free interest rate for periods commensurate with the expected term of the option is based on the U.S. Treasury yield rate in effect at the time of grant. The expected dividend yield is zero, as the Company currently does not pay a dividend and does not anticipate doing so in the future.

The grant-date fair values of awards granted under the 1999 ESPP during the years ended December 31, 2022, 2021 and 2020 were estimated using the Black-Scholes option pricing model with the following weighted-average assumptions:

	2022		2021		2020
Expected term (in years)	0.5		0.5		0.5
Risk-free interest rate	1.9	%	0.1	%	0.7	%
Expected volatility	26.0	%	32.2	%	30.4	%
Dividend yield	—	%	—	%	—	%

For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of awards granted under the 1999 ESPP was $33.26 per share, $36.17 per share and $32.30 per share, respectively.

As of December 31, 2022, total pre-tax unrecognized compensation cost for stock options, restricted stock units, deferred stock units and shares of common stock issued under the 1999 ESPP was $399.3 million. The expense is expected to be recognized through 2025 over a weighted average period of 2.0 years.

Stock Options

Stock option activity during the year ended December 31, 2022 was as follows:

	Shares (in thousands)	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at January 1, 2022	1	$	41.08
Exercised	—	40.44
Outstanding at December 31, 2022	1	$	41.28	0.6	$	43
Exercisable at December 31, 2022	1	$	41.28	0.6	$	43
Vested or expected to vest December 31, 2022	1	$	41.28	0.6	$	43

The total pre-tax intrinsic value of options exercised during the year ended December 31, 2022 was insignificant. The total pre-tax intrinsic value of options exercised during the years ended December 31, 2021 and 2020 were $0.6 million and $1.0 million, respectively. No options vested during the years ended December 31, 2022, 2021 and 2020.

The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $84.30 on December 31, 2022, that would have been received by the option holders had all option holders exercised their “in-the-money” options as of that date. The total number of shares issuable upon the exercise of “in-the-money” options exercisable as of December 31, 2022 was 1,002.

Deferred Stock Units

The Company has granted deferred stock units ("DSUs") to non-employee members of its board of directors. Each DSU represents the right to receive one share of the Company’s common stock upon vesting. The holder may elect to defer receipt of the vested shares of stock represented by the DSU for a period of at least one year but not more than ten years from the grant date. DSUs vest 100% on the first anniversary of the grant date. If a director has completed one year of service, vesting of 100% of the DSUs held by such director will accelerate at the time of his or her departure from the board.

DSU activity for the year ended December 31, 2022 was as follows:

	Units (in thousands)	Weighted Average Grant Date Fair Value
Outstanding at January 1, 2022	98	$	72.96
Granted	27	97.40
Vested and distributed	(45)	73.33
Outstanding at December 31, 2022	80	$	81.11

The total pre-tax intrinsic value of DSUs that were vested and distributed during the years ended December 31, 2022, 2021 and 2020 was $4.9 million, $4.1 million and $0.9 million, respectively. The total fair value of DSUs that were vested and distributed during the years ended December 31, 2022, 2021 and 2020 was $3.3 million, $2.7 million and $0.7 million, respectively. The grant-date fair value is calculated based upon the Company’s closing stock price on the date of grant. For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of DSU awards granted was $97.40 per share, $114.56 per share and $100.58 per share, respectively. As of December 31, 2022, 27,306 DSUs were unvested, with an aggregate intrinsic value of approximately $2.3 million and a weighted average remaining contractual life of approximately 0.4 years. These units are expected to vest in May 2023.

85

Restricted Stock and Restricted Stock Units

Different types of restricted stock units ("RSUs") granted by the Company during the year ended December 31, 2022 were as follows (in thousands):

	December 31, 2022
RSUs with service-based vesting conditions	3,243
RSUs with market-based vesting conditions	81
RSUs with performance-based vesting conditions	239
Total	3,563

RSUs represent the right to receive one share of the Company’s common stock upon vesting. RSUs are granted at the discretion of the board of directors, a committee thereof or, subject to defined limitations, the Chief Executive Officer of the Company, acting as a committee of one director, to whom such authority has been delegated. The Company has issued RSUs that vest based on the passage of time assuming continued service with the Company, RSUs that vest based upon total shareholder return ("TSR") measured against the benchmark TSR of a peer group and RSUs that vest only upon the achievement of defined performance metrics tied primarily to revenue and earnings targets.

For RSUs with service-based vesting conditions, the fair value is calculated based upon the Company’s closing stock price on the date of grant, and the stock-based compensation expense is being recognized over the vesting period. Most RSUs with service-based vesting provisions vest in installments over a three- or four-year period following the grant date.

The Company uses the Monte Carlo simulation model to determine the fair value of the Company's RSUs based on TSR. This model requires the input of assumptions, including the estimated term of each award, the risk-free interest rate, historical stock price volatility of the Company's shares and historical stock price volatility of peer-company shares. The grant-date fair values of the TSR-based RSUs granted during the years ended December 31, 2022, 2021 and 2020 were estimated using a Monte Carlo simulation model with the following assumptions:

	2022		2021		2020
Expected term (in years)	3.0		3.0		3.0
Risk-free interest rate	1.7	%	0.3	%	0.7	%
Akamai historical share price volatility	30.3	%	32.7	%	28.2	%
Average volatility of peer-company share price	40.7	%	39.6	%	28.9	%

For the years ended December 31, 2022, 2021 and 2020, management measured compensation expense for performance-based RSUs based upon a review of the Company’s expected achievement against specified financial performance targets. Such compensation cost is being recorded using a graded-vesting method for each series of grants of performance-based RSUs, to the extent management has deemed that such awards are probable of vesting based upon the expected achievement against the specified targets. On a periodic basis, management reviews the Company’s expected performance and adjusts the compensation cost, if needed, at such time.

RSU activity for the year ended December 31, 2022 was as follows:

	Units (in thousands)	Weighted Average Grant Date Fair Value
Outstanding at January 1, 2022	4,389	$	95.75
Granted	3,563	107.17
Vested	(2,096)	110.57
Forfeited	(578)	102.92
Outstanding at December 31, 2022	5,278	$	121.92

86

The shares granted during 2022 and presented in the table above include 172,271 RSUs assumed by the Company as a result of the acquisition of Linode.

The total pre-tax intrinsic value of RSUs that vested during the years ended December 31, 2022, 2021 and 2020 was $227.1 million, $226.4 million and $192.5 million, respectively. The total fair value of RSUs that vested during the years ended December 31, 2022, 2021 and 2020 was $231.7 million, $233.0 million and $198.9 million, respectively. The grant-date fair value of each RSU is calculated based upon the Company’s closing stock price on the date of grant. For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of RSU awards granted was $107.17 per share, $99.09 per share and $92.42 per share, respectively. As of December 31, 2022, 5.3 million RSUs were outstanding and unvested, with an aggregate intrinsic value of $445.1 million and a weighted average remaining vesting period of approximately 2.3 years.

Valuation allowances will be recognized on deferred tax assets if it is more-likely-than-not that some or all of the deferred tax assets will not be utilized. In measuring deferred tax assets, the Company considers all available evidence, both positive and negative, to determine whether a valuation allowance is needed. As of December 31, 2022, the Company recorded a $41.3 million valuation allowance against deferred tax assets related to state tax credits and state and foreign NOLs in which it is more-likely-than-not that such attributes will expire prior to utilization. The increase in the valuation allowance during 2022 was $4.1 million. The increase in the valuation allowance is primarily related to state tax credits.

The Company's NOL and tax credit carryforwards in U.S. federal, state and foreign jurisdictions as of December 31, 2022 and 2021 were as follows (in thousands, except years):

	2022		2021		Expirations at Various Dates Through:
NOL carryforwards:
Federal	$	30,100	$	44,000	2037
State	22,400		15,500		2042
Foreign	40,100		180,100		2037
Federal and state research and development tax credit and other credit carryforwards	121,300		113,500		2037

The Company's U.S. federal and state NOL carryforwards relate to acquisitions completed in 2022, 2021, 2019, 2017 and 2012.

As of December 31, 2022, accumulated earnings outside the U.S. totaled $1.9 billion, the majority of which have been taxed due to the one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings and the tax on global intangible low taxed income required by the U.S. Tax Cuts and Jobs Act ("TCJA"). No provision for U.S. state income taxes and foreign withholding taxes has been provided for any remaining undistributed foreign earnings not subject to tax under the TCJA, or any additional basis differences inherent in the Company's international subsidiaries, as these amounts continue to be indefinitely reinvested. Determination of the amount of the unrecognized deferred tax liability on outside basis differences is not practicable because of the complexity of laws and regulations, the varying tax treatment of alternative repatriation scenarios and the variation due to multiple potential assumptions relating to the timing of any future repatriation.

The changes in the Company’s unrecognized tax benefits for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

	2022		2021		2020
Balance at beginning of year	$	22,563	$	24,105	$	27,359
Gross increases – tax positions of prior periods	3,880		4,293		2,539
Gross increases – current period tax positions	45,975		3,607		1,946
Gross decreases – tax positions of prior periods	(688)		(816)		(3,540)
Gross decreases – lapse of applicable statute of limitations	(3,772)		(8,626)		(4,199)
Balance at end of year	$	67,958	$	22,563	$	24,105

As of December 31, 2022, 2021 and 2020, the Company had $38.3 million, $23.1 million and $29.5 million of unrecognized tax benefits, respectively. Total interest and penalties for unrecognized tax benefits includes $8.6 million, $7.2 million and $7.7 million as of December 31, 2022, 2021 and 2020, respectively. Interest and penalties related to unrecognized tax benefits are recorded in the provision for income taxes and were $2.0 million, $0.5 million and $1.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. The amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate is $38.3 million.

As of December 31, 2022, it is reasonably possible that $3.6 million of unrecognized tax benefits may be recognized within the next 12 months due to the expiration of local statutes of limitations. Certain U.S. state and foreign income tax returns from 2013 through 2022 are currently under audit. The Company has reserved for those positions that are not more-likely-than-not to be sustained.

20. Net Income per Share

Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock options, RSUs, DSUs, convertible senior notes and warrants issued by the Company. For the year ended December 31, 2022, the dilutive effect of outstanding awards is reflected in diluted earnings per share by application of the treasury stock method and the dilutive effect of the convertible securities is reflected in diluted earnings per share by application of the if-converted method. For the years ended December 31, 2021 and 2020, the dilutive effect of outstanding awards and convertible securities is reflected in diluted earnings per share by application of the treasury stock method.

The components used in the computation of basic and diluted net income per share for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands, except per share data):

	2022		2021		2020
Numerator:
Net income	$	523,672	$	651,642	$	557,054
Denominator:

Effect of dilutive securities:
Stock options	21		21		31
RSUs and DSUs	637		1,518		1,819
Convertible senior notes	720		1,600		873
Warrants related to issuance of convertible senior notes	—		—		—
Shares used for diluted net income per share	160,467		165,804		165,213
Basic net income per share	$	3.29	$	4.01	$	3.43
Diluted net income per share	$	3.26	$	3.93	$	3.37

For the years ended December 31, 2022, 2021 and 2020, certain potential outstanding shares from service-based RSUs, convertible notes and warrants were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain performance-based RSUs were excluded from the computation of diluted net income per share because the underlying performance conditions for such RSUs had not been met as of these dates. The number of potentially outstanding shares excluded from the computation of diluted net income per share for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

	2022	2021	2020
Service-based RSUs	2,211	776	591
Market- and performance-based RSUs	1,030	1,199	1,409

Warrants related to issuance of convertible senior notes	21,991	21,991	21,991
Total shares excluded from computation	25,232	33,864	36,913

21. Akamai Foundation

The Akamai Foundation is a private non-profit organization founded in 2000 by certain current and former employees of the Company (the “Foundation”). The Company has the right to appoint the directors of the Foundation, but receives no economic benefit from the Foundation’s initiatives, therefore the Foundation is not consolidated. The Foundation's initiatives are to support youth education, with a focus on mathematics and science, as well as other charitable causes. In 2020, the Foundation expanded its initiatives to include supporting increased diversity in the technology industry. The Company contributed $20.0 million in that year in support of the Foundation's expanded initiatives. This expense is included in general and administrative expenses in the consolidated statements of income for the year ended December 31, 2020.

22. Segment and Geographic Information

The Company’s chief operating decision-maker is the chief executive officer and the executive management team. As of December 31, 2022, the Company is currently organized and operates as one reportable and operating segment. The Company is not organized by market and is managed and operated as one business. A single management team that reports to the chief executive officer comprehensively manages the entire business. The Company does not operate any material separate lines of business or separate business entities with respect to its services. Accordingly, the Company does not accumulate discrete financial information with respect to separate entities and does not have separate operating or reportable segments.

The Company deploys its servers into networks worldwide. Net property and equipment, excluding internal-use software and operating lease right-of-use assets, located in the U.S. and foreign locations, as of December 31, 2022 and 2021 was as follows (in thousands):

23. Quarterly Financial Data (Unaudited)

Revision of Previously Issued Financial Statements

During the preparation of the financial statements for the year ended December 31, 2022, an error was identified in the Company’s accounting for an intercompany sale of intellectual property that occurred during 2022. During each of the first three quarters of 2022, the Company failed to record a deferred tax asset in the jurisdiction where the intellectual property was sold for the step up in tax basis that was achieved with the sale. This caused net deferred taxes to be understated in the interim condensed consolidated balance sheets, the provision for income taxes to be overstated and net income and earnings per share to be understated in the interim condensed consolidated statements of income. Management evaluated the error and determined that the related impact was not material to any of the Company's previously issued financial statements.

The financial data below has been derived from the Company’s quarterly reports on Form 10-Q filed for the respective periods, with 2022 periods adjusted to reflect the impact of the error. The Company will also correct previously reported financial information for this error in its future filings, as applicable.

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2022, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective to provide reasonable assurance due to a material weakness in internal control over financial reporting described below.

Management’s Annual Report on Internal Control over Financial Reporting

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and

93

the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

•pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022. Based on this assessment, our management concluded that as of December 31, 2022, our internal control over financial reporting was not effective as of December 31, 2022, due to a material weakness in internal control over financial reporting described below. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013).

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

A material weakness in internal control over financial reporting related to income taxes was identified in the Company’s internal control over financial reporting as of December 31, 2022. Specifically, the Company did not design and maintain effective controls over the adoption and application of new accounting standards related to income taxes.

This material weakness resulted in immaterial errors to net deferred tax assets and provision for income taxes for the interim periods ended March 31, 2022, June 30, 2022 and September 30, 2022. These immaterial errors also resulted in a revision to previously issued quarterly financial statements for each of these periods. Additionally, this material weakness could result in misstatements of the aforementioned account balances or disclosures that would result in a material misstatement to the Company's annual or interim consolidated financial statements that would not be prevented or detected.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2022 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report, which is included in Item 8 of this annual report on Form 10-K.

Remediation Plan

The Company’s management, under the oversight of the Audit Committee, is in the process of designing and implementing changes in processes and controls to remediate the material weakness. We expect our remediation plan to include the enhancement of the design and precision of our process for evaluating the adoption and application of new accounting standards in the area of income taxes, including the involvement of external tax advisors, as applicable.

The material weakness will not be considered remediated until management completes its remediation plan and the enhanced controls operate for a sufficient period of time and management has concluded, through testing, that the related controls are effective. The Company will monitor the effectiveness of its remediation plan and will refine its remediation plan as appropriate.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the fourth quarter ended December 31, 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

None.

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections

EX-10.9

Exhibit 10.9

AKAMAI TECHNOLOGIES, INC.

Performance-Based Restricted Stock Unit Agreement

Granted Under the 2013 Stock Incentive Plan

1.Grant of Award.

    This Agreement evidences the grant by Akamai Technologies, Inc., a Delaware corporation (the “Company”), on _____, 202_ (the “Grant Date”) to you (the “Participant”) of restricted stock units of the Company (individually, an “RSU” and collectively, the “RSUs”), subject to the terms and conditions set forth in this Restricted Stock Unit Agreement, including any additional terms for the Participant’s country set forth in the appendix attached hereto (the “Appendix”) (together, the “Agreement”) and the 2013 Stock Incentive Plan and any sub-plan to the 2013 Stock Incentive Plan for the Participant’s country (the “Sub-Plan”) (together, as amended or amended and restated, the “Plan”). Each RSU represents the right to receive one share of the common stock, par value $.01 per share, of the Company (“Common Stock”) as provided in this Agreement. The target number of shares issuable is _____________ (the “Target Number of Shares”). The maximum number of shares issuable is ___% of the Target Number of Shares. The number of shares of Common Stock issuable upon vesting of the RSUs shall be calculated pursuant to the provisions of Schedule 1 and are referred to in this Agreement as “Shares.” Capitalized terms used but not defined in this Agreement shall have the meanings specified in the Plan.

2.Vesting; Forfeiture.

    (a)    Subject to the terms and conditions of this Agreement including, without limitation, Section 2(b) below and Section 6 below, the number of Shares issuable pursuant to the calculation set forth in Schedule 1 to this Agreement, if any, shall vest on the date on which the Board of Directors of the Company, or a committee thereof (as applicable, the “Talent, Leadership & Compensation Committee”), certifies the Company’s financial performance for fiscal year 202_. Such date or any other date on which RSUs vest under this Agreement may be referred to herein as a “Vesting Date.”

    (b)    Except as otherwise provided in Schedule 1, RSUs shall not continue to vest unless the Participant is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the Company. For purposes of the Agreement, employment with the Company shall include employment with a parent, subsidiary, affiliate or division of the Company, subject to Section 8(g) of the Agreement. For the avoidance of doubt, employment during only a portion of the vesting period, and where the Participant’s employment has terminated prior to a Vesting Date, will not entitle the Participant to vest in a pro-rata portion of the RSUs, unless otherwise provided in this Agreement.

3.Distribution of Shares.

(a)The Company will distribute to the Participant (or to the Participant’s estate in the event that his or her death occurs after a Vesting Date but before distribution of the corresponding Shares), the shares of Common Stock represented by RSUs that vested on such Vesting Date as soon as administratively practicable after each Vesting Date (each such date of distribution is hereinafter referred to as a “Settlement Date”) but in any event within the period ending on the later to occur of the date that is two and one-half months from the end of (i) the Participant’s tax year that includes the applicable Vesting Date or (ii) the Company’s tax year that includes the applicable Vesting Date.

(b)The Company shall not be obligated to issue to the Participant the Shares upon the vesting of any RSU (or otherwise) unless the issuance and delivery of such Shares shall comply with all relevant provisions of law and other legal requirements including, without limitation, any applicable federal, state or local securities laws and the requirements of any stock exchange upon which shares of Common Stock may then be listed.

- 1 -

(c)Neither the Company nor the Participant shall have the right to accelerate or defer the delivery of any shares under this Agreement except to the extent specifically permitted under Section 409A of the Code.

4.Restrictions on Transfer.

The Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise (collectively “transfer”) any RSUs, or any interest therein, except by will or the laws of descent and distribution.

5.Dividend and Other Shareholder Rights.

Except as set forth in the Plan, neither the Participant nor any person claiming under or through the Participant shall be, or have any rights or privileges of, a stockholder of the Company in respect of the Shares issuable pursuant to the RSUs granted hereunder until the Shares have been delivered to the Participant.

6.Provisions of the Plan; Acquisition Event or Change in Control Event.

(a)This Agreement is subject to the provisions of the Plan, a copy of which is made available to the Participant with this Agreement.

(b)[Reserved].

(c)Upon the occurrence of a Change in Control Event, provided that the Participant is employed by the Company as of the date of the Change in Control Event, then effective immediately prior to the occurrence of the Change in Control Event, the Participant shall be deemed to have earned any then-unvested RSUs as follows: the number of RSUs that shall be deemed earned shall be equal to the then-outstanding number of unvested RSUs issuable upon achievement of (i) actual performance of the applicable metrics set forth on Schedule 1 for any RSUs for which the Performance Year has been fully completed as of the date of the Change in Control Event and (ii) target level performance of the applicable metrics set forth on Schedule 1 for any RSUs for which the Performance Year has not been completed or has been partially completed as of the date of the Change in Control Event (any RSUs that are deemed earned pursuant to this Section 6(c), are referred to as “Earned RSUs”). Any RSUs that are not deemed Earned RSUs pursuant to this Section 6(c) shall immediately terminate and be forfeited upon the Change in Control Event.

(d)In the event that the parties to such Change in Control Event do not provide for the assumption, continuation or substitution of the Earned RSUs in connection with a Change in Control Event, 100% of the Earned RSUs shall become vested immediately prior to the Change in Control Event. For purposes of this Section 6(d), the Earned RSUs shall be considered assumed, continued or substituted if, following consummation of the Change in Control Event, the Earned RSUs confer the right to purchase or receive, for each Earned RSU, the consideration (whether cash, securities or other property) received as a result of the Change in Control Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Change in Control Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Change in Control Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the settlement of the Earned RSUs to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Change in Control Event.

(e)In the event that the parties to such Change in Control Event provide for the assumption, continuation or substitution of the Earned RSUs in connection with a Change in Control Event, such Earned RSUs shall remain subject to time-based vesting and shall vest in full on December

- 2 -

31, 2024, subject to the Participant’s continued employment through such date; provided, however, in the event that the Participant’s employment is terminated by the acquiring or succeeding entity (or an affiliate thereof) for a reason other than Cause (as defined below) or by the Participant for Good Reason (as defined below), in either case within twelve (12) months after the Change in Control Event, 100% of the Earned RSUs shall become vested as of the date of the Participant’s termination of employment as determined in accordance with Section 8(l) below. “Cause” shall mean (i) any act or omission by the Participant that has a significant adverse effect on Akamai’s (or the acquiring or succeeding company’s) business or on the Participant’s ability to perform services for Akamai or the acquiring or succeeding company, including, without limitation, the commission of any crime (other than ordinary traffic violations), (ii) refusal or failure to perform assigned duties, serious misconduct, or excessive absenteeism, or (iii) refusal or failure to comply with Akamai’s or the acquiring or succeeding entity’s Code of Business Ethics. “Good Reason” shall mean (i) a material reduction in the Participant’s compensation and benefits (including, without limitation, any bonus plan or indemnity agreement not agreed to in writing by the Participant), (ii) the assignment to the Participant of duties and/or responsibilities that are materially inconsistent with those associated with the Participant’s position, or (iii) a requirement, not agreed to in writing by the Participant, that the Participant relocate to, or perform his or her principal job functions at, an office that is more than twenty-five (25) miles from the office at which the Participant was previously performing his or her principal job functions.

7.Withholding Taxes.

(a)The Participant acknowledges that, regardless of any action the Company or, if different, the parent, subsidiary, affiliate or division of the Company by which the Participant is employed (the “Employer”) takes with respect to any or all income tax, social insurance contributions, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable to the Participant or deemed by the Company or the Employer, in its discretion, to be an appropriate charge to the Participant even if legally applicable to the Company or the Employer (“Tax-Related Items”), the ultimate liability for all Tax-Related Items legally due by him or her is and remains the Participant’s responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSU award, including the grant, vesting or settlement of the RSUs, the subsequent sale of Shares delivered pursuant thereto and the receipt of cash or any dividends or dividend equivalents; and (2) do not commit to structure the terms of the award or any aspect of the RSUs to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to tax in more than one jurisdiction, the Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction

(b)The Company and/or the Employer, or their respective agents, retain the discretion, and the Participant authorizes the Company and/or the Employer, or their respective agents, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (i) withholding from the Participant’s wages or other cash compensation paid to the Participant by the Company and/or the Employer; (ii) withholding from proceeds of the sale of Shares acquired upon vesting of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent); (iii) requiring the Participant to make a payment in a form acceptable to the Company; (iv) withholding in Shares to be issued upon settlement of the RSUs; or (v) any other method of withholding determined by the Company and to the extent required by applicable law or the Plan, approved by the Committee.

(c)The Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates in the Participant’s jurisdiction(s), to the extent permitted by the Plan. In the event of over-withholding, the Participant may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or if not refunded, the Participant may seek a refund from the local tax authorities. In the event of under-withholding, the Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes,

- 3 -

the Participant is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items.

(d)Finally, the Participant shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Participant’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Participant fails to comply with the Participant’s obligations with respect to Tax-Related Items.

(e)The Participant represents to the Company that, as of the date hereof, he or she is not aware of any material nonpublic information about the Company or the Common Stock. The Participant and the Company have structured this Agreement to constitute a “binding contract” relating to the sale of Common Stock pursuant to this Section 7, consistent with the affirmative defense to liability under Section 10(b) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) under Rule 10b5-1(c) promulgated under such Act.

8.Nature of Grant. In accepting the grant, the Participant acknowledges that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the Plan;

(b)the grant of the RSUs is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

(c)all decisions with respect to future restricted stock units, if any, will be at the sole discretion of the Company;

(d)the grant of the RSUs and the Participant’s participation in the Plan will not create a right to further employment with the Company or the Employer, as applicable. and shall not interfere with the ability of the Company, the Employer or any parent, subsidiary or affiliate of the Company, as applicable, to terminate Participant’s employment relationship at any time;

(e)the Participant is voluntarily participating in the Plan;

(f)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(g)the RSUs and the Participant’s participation in the Plan will not be interpreted to form an employment agreement or relationship with the Company;

(h)the future value of the Shares subject to the RSUs is unknown, indeterminable and cannot be predicted with certainty;

(i)unless otherwise agreed with the Company, the RSUs and the Shares subject to the RSUs, and the income and value of same, are not granted as consideration for, or in connection with, any service the Participant may provide as a director of any parent, subsidiary or affiliate of the Company;

(j)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, holiday pay, bonuses, long-service awards, leave-related payments, pension, retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or the Employer;

- 4 -

(k)no claim or entitlement to compensation or damages shall arise from any forfeiture of the RSUs resulting from termination of the Participant’s employment relationship (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or providing services or the terms of the Participant’s employment agreement, if any); and

(l)for purposes of the RSUs, the Participant’s employment relationship will be considered terminated as of the date he or she is no longer actively providing services to the Company, the Employer or any other parent, subsidiary or affiliate of the Company (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or providing services or the terms of his or her employment agreement, if any) and, except in the case of termination due to death or disability or an Eligible Retiree Participant as provided for in Schedule 1, the Participant’s right to vest in the RSUs under the Plan, if any, will terminate effective as of such date and will not be extended by any notice period (e.g., the period of the Participant’s employment service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is employed or providing services or the terms of his or her employment agreement, if any); the Committee shall have the exclusive discretion to determine when the Participant is no longer actively providing services for purposes of his or her RSUs (including whether the Participant may still be considered to be providing services while on a leave of absence).

9.    Data Privacy Information and Consent.

(a)Data Collection and Usage. The Company and the Employer collect, process and use certain personal information about the Participant, including, but not limited to, his or her name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all awards granted under the Plan or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in the Participant’s favor (“Data”), for purposes of administering his or her participation in the Plan. The legal basis, where required, for the processing of Data is the Participant’s consent.

(b)Stock Plan Administration Service Providers. The Company transfers Data to Charles Schwab & Co., Inc. and certain of its affiliates (“Charles Schwab”), which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Participant may be asked to agree on separate terms and data processing practices with Charles Schwab, with such agreement being a condition to the ability to participate in the Plan.

(c)International Data Transfers. The Company, Charles Schwab and, as the case may be, other service providers of the Company are or might be based in the United States, which means that the Participant’s Data will have to be transferred to or otherwise processed in the United States. The Participant understands and acknowledges that the United States might apply laws not providing a level of protection of his or her Data equivalent to the level of protection in his or her country or jurisdiction. In the absence of appropriate safeguards, the processing of the Participant’s Data in the United States might not be subject to substantive data processing principles or supervision by data protection authorities. In addition, the Participant might not have enforceable rights regarding the processing of his or her Data. By signing or electronically agreeing to this Agreement, the Participant explicitly declares his or her consent to the Company receiving and transferring his or her Data onward to Charles Schwab and, as the case may be, other service providers without implementing appropriate safeguards. Where required, such processing of the Participant’s Data will be exclusively based on his or her consent.

(d)Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws. This period may extend beyond the Participant’s period of employment with the

- 5 -

Employer. When the Company or the Employer no longer need Data for any of the above purposes, they will cease processing it in this context and remove it from all of their systems used for such purposes to the fullest extent practicable.

(e)Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Participant is providing the consents herein on a purely voluntary basis. If the Participant does not consent, or if the Participant later seeks to revoke the consent, his or her salary from or employment with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant awards under the Plan or administer or maintain such awards.

(f)Data Subject Rights. The Participant may have a number of rights under data privacy laws in his or her jurisdiction. Depending on where the Participant is based, such rights may include the right to (i) request access to or copies of Data processes, (ii) rectify incorrect Data, (iii) delete Data, (iv) restrict the processing of Data, (v) restrict the portability of Data, (vi) lodge complaints with competent authorities in his or her jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data. To receive clarification regarding these rights or to exercise these rights, the Participant can contact his or her local human resources representative.

(g)Other Legal Basis and Additional Consent. The Participant understands that the Company may rely on a different legal basis for the collection, processing or transfer of Data in the future and/or request the Participant to provide another data privacy consent. If applicable, upon request of the Participant or the Employer, he or she will provide a separate executed data privacy agreement (or any other agreements or consents) that the Company and/or the Employer may deem necessary to obtain from the Participant for the purpose of administering his or her participation in the Plan in compliance with the data privacy laws in his or her country, either now or in the future. The Participant understands and agrees that he or she will not be able to participate in the Plan, if he or she fails to provide any such agreement requested by the Company and/or the Employer.

10.Miscellaneous.

(l)Amendment. The Company may modify, amend or waive the terms of this Agreement prospectively or retroactively, but no such modification, amendment or waiver shall impair the rights of the Participant without his or her consent, except as required by applicable law, Nasdaq or stock exchange rules, tax rules or accounting rules. Any provision for the benefit of the Company contained in this Agreement may be waived, either generally or in any particular instance, by the Board of Directors (or a committee thereof) of the Company.

(p)Insider Trading/Market Abuse Laws.

Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Participant placed before he or she possessed inside information. Furthermore, the Participant could be prohibited from (i) disclosing the inside information to any third party and (ii) “tipping” third parties or causing them to otherwise to buy or sell securities.

B.    Effect of an Acquisition or Disposition by Akamai

    In the event that Akamai closes an Acquisition Transaction or Disposition Transaction during the Performance Year, the Talent, Leadership & Compensation Committee shall make adjustments to affected performance targets for such Performance Year to give effect to the expected impact on such targets of the applicable Acquisition Transaction or Disposition Transaction (including whether it is accretive or not) based on management’s good faith estimate of the projected impact as presented to the Talent, Leadership & Compensation Committee. An “Acquisition Transaction” means (i) the purchase of more than 50% of the voting power of an entity, (ii) any merger, reorganization, consolidation, recapitalization, business combination, liquidation, dissolution or share exchange involving Akamai and an entity not previously owned by Akamai, or (iii) the purchase or other acquisition (including, without limitation, via license outside of the ordinary course of business or joint venture) of assets that constitute more than 50% of another entity’s total assets or assets that account for more than 50% of the consolidated net revenues or net income of such entity. A “Disposition Transaction” means the sale of a division, business unit or set of business operations and/or related assets to a third party.

All determinations of the Talent, Leadership & Compensation Committee regarding the estimated impact of an Acquisition Transaction or a Disposition Transaction shall be final, binding and non-appealable.

This Schedule 1 shall be deemed to be automatically amended, without further action by the Company or the executive, to give effect to any adjustments required by this Section B.

C.    Effect of Death or Disability of the Participant

(1)    If the Participant dies or is disabled (within the meaning of Section 409A of the Code) prior to the end of the first Performance Year, then a pro-rated number of Shares, based on an assumed performance that would lead to vesting of the Target Number of RSUs shall vest based on the number of days into the three-year vesting Performance Period the date of death or disability occurred and such RSUs shall be delivered to the Participant or the Participant’s estate within 30 days following such death or disability.

(2)    If the Participant dies or is disabled (within the meaning of Section 409A of the Code) after the end of one or more completed Performance Years, then a pro-rated number of Shares, based on an the actual number of RSUs that are eligible for vesting based on the Company’s actual performance for any completed Performance Year(s) plus the Target Number of RSUs for the Performance Year in which the death or disability occurs, shall vest based on the number of days into the three-year vesting period the date of death or disability occurred and such RSUs shall be delivered to the Participant or the Participant’s estate within 30 days following such death or disability.

(3)    If the provisions of Sections 6(c)-(e) of the Agreement are triggered, such provisions shall take precedence over those set forth in this Paragraph C.

Exhibit 10.12

AKAMAI TECHNOLOGIES, INC.

Performance-Based Restricted Stock Unit Agreement

Granted Under the 2013 Stock Incentive Plan

1.Grant of Award.

    This Agreement evidences the grant by Akamai Technologies, Inc., a Delaware corporation (the “Company”), on _____, 202_ (the “Grant Date”) to you (the “Participant”) of restricted stock units of the Company (individually, an “RSU” and collectively, the “RSUs”), subject to the terms and conditions set forth in this Restricted Stock Unit Agreement, including any additional terms for the Participant’s country set forth in the appendix attached hereto (the “Appendix”) (together, the “Agreement”) and the 2013 Stock Incentive Plan and any sub-plan to the 2013 Stock Incentive Plan for the Participant’s country (the “Sub-Plan”) (together, as amended or amended and restated, the “Plan”). Each RSU represents the right to receive one share of the common stock, par value $.01 per share, of the Company (“Common Stock”) as provided in this Agreement. The target number of shares issuable is _____________ (the “Target Number of Shares”). The maximum number of shares issuable is ___% of the Target Number of Shares. The number of shares of Common Stock issuable upon vesting of the RSUs shall be calculated pursuant to the provisions of Schedule 1 and are referred to in this Agreement as “Shares.” Capitalized terms used but not defined in this Agreement shall have the meanings specified in the Plan.

2.Vesting; Forfeiture.

    (a)    Subject to the terms and conditions of this Agreement including, without limitation, Section 2(b) below and Section 6 below, the number of Shares issuable pursuant to the calculation set forth in Schedule 1 to this Agreement, if any, shall vest on the date on which the Board of Directors of the Company, or a committee thereof (as applicable, the “Talent, Leadership & Compensation Committee”), certifies the Company’s financial performance for fiscal year 202_. Such date or any other date on which RSUs vest under this Agreement may be referred to herein as a “Vesting Date.”

    (b)    Except as otherwise provided in Schedule 1, RSUs shall not continue to vest unless the Participant is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the Company. For purposes of the Agreement, employment with the Company shall include employment with a parent, subsidiary, affiliate or division of the Company, subject to Section 8(g) of the Agreement. For the avoidance of doubt, employment during only a portion of the vesting period, and where the Participant’s employment has terminated prior to a Vesting Date, will not entitle the Participant to vest in a pro-rata portion of the RSUs, unless otherwise provided in this Agreement.

3.Distribution of Shares.

(a)The Company will distribute to the Participant (or to the Participant’s estate in the event that his or her death occurs after a Vesting Date but before distribution of the corresponding Shares), the shares of Common Stock represented by RSUs that vested on such Vesting Date as soon as administratively practicable after each Vesting Date (each such date of distribution is hereinafter referred to as a “Settlement Date”) but in any event within the period ending on the later to occur of the date that is two and one-half months from the end of (i) the Participant’s tax year that includes the applicable Vesting Date or (ii) the Company’s tax year that includes the applicable Vesting Date.

(b)The Company shall not be obligated to issue to the Participant the Shares upon the vesting of any RSU (or otherwise) unless the issuance and delivery of such Shares shall comply with all relevant provisions of law and other legal requirements including, without limitation, any applicable federal, state or local securities laws and the requirements of any stock exchange upon which shares of Common Stock may then be listed.

- 1 -

(c)Neither the Company nor the Participant shall have the right to accelerate or defer the delivery of any shares under this Agreement except to the extent specifically permitted under Section 409A of the Code.

4.Restrictions on Transfer.

The Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise (collectively “transfer”) any RSUs, or any interest therein, except by will or the laws of descent and distribution.

5.Dividend and Other Shareholder Rights.

Except as set forth in the Plan, neither the Participant nor any person claiming under or through the Participant shall be, or have any rights or privileges of, a stockholder of the Company in respect of the Shares issuable pursuant to the RSUs granted hereunder until the Shares have been delivered to the Participant.

6.Provisions of the Plan; Acquisition Event or Change in Control Event.

(a)This Agreement is subject to the provisions of the Plan, a copy of which is made available to the Participant with this Agreement.

(b)[Reserved].

(c)Upon the occurrence of a Change in Control Event, provided that the Participant is employed by the Company as of the date of the Change in Control Event, then effective immediately prior to the occurrence of the Change in Control Event, the Participant shall be deemed to have earned any then-unvested RSUs as follows: the number of RSUs that shall be deemed earned shall be equal to the then-outstanding number of unvested RSUs issuable upon achievement of (i) actual performance of the applicable metrics set forth on Schedule 1 for any RSUs for which the Performance Year has been fully completed as of the date of the Change in Control Event and (ii) target level performance of the applicable metrics set forth on Schedule 1 for any RSUs for which the Performance Year has not been completed or has been partially completed as of the date of the Change in Control Event (any RSUs that are deemed earned pursuant to this Section 6(c), are referred to as “Earned RSUs”). Any RSUs that are not deemed Earned RSUs pursuant to this Section 6(c) shall immediately terminate and be forfeited upon the Change in Control Event.

(d)In the event that the parties to such Change in Control Event do not provide for the assumption, continuation or substitution of the Earned RSUs in connection with a Change in Control Event, 100% of the Earned RSUs shall become vested immediately prior to the Change in Control Event. For purposes of this Section 6(d), the Earned RSUs shall be considered assumed, continued or substituted if, following consummation of the Change in Control Event, the Earned RSUs confer the right to purchase or receive, for each Earned RSU, the consideration (whether cash, securities or other property) received as a result of the Change in Control Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Change in Control Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Change in Control Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the settlement of the Earned RSUs to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Change in Control Event.

(e)In the event that the parties to such Change in Control Event provide for the assumption, continuation or substitution of the Earned RSUs in connection with a Change in Control Event, such Earned RSUs shall remain subject to time-based vesting and shall vest in full on December

- 2 -

31, 2024, subject to the Participant’s continued employment through such date; provided, however, in the event that the Participant’s employment is terminated by the acquiring or succeeding entity (or an affiliate thereof) for a reason other than Cause (as defined below) or by the Participant for Good Reason (as defined below), in either case within twelve (12) months after the Change in Control Event, 100% of the Earned RSUs shall become vested as of the date of the Participant’s termination of employment as determined in accordance with Section 8(l) below. “Cause” shall mean (i) any act or omission by the Participant that has a significant adverse effect on Akamai’s (or the acquiring or succeeding company’s) business or on the Participant’s ability to perform services for Akamai or the acquiring or succeeding company, including, without limitation, the commission of any crime (other than ordinary traffic violations), (ii) refusal or failure to perform assigned duties, serious misconduct, or excessive absenteeism, or (iii) refusal or failure to comply with Akamai’s or the acquiring or succeeding entity’s Code of Business Ethics. “Good Reason” shall mean (i) a material reduction in the Participant’s compensation and benefits (including, without limitation, any bonus plan or indemnity agreement not agreed to in writing by the Participant), (ii) the assignment to the Participant of duties and/or responsibilities that are materially inconsistent with those associated with the Participant’s position, or (iii) a requirement, not agreed to in writing by the Participant, that the Participant relocate to, or perform his or her principal job functions at, an office that is more than twenty-five (25) miles from the office at which the Participant was previously performing his or her principal job functions.

7.Withholding Taxes.

(a)The Participant acknowledges that, regardless of any action the Company or, if different, the parent, subsidiary, affiliate or division of the Company by which the Participant is employed (the “Employer”) takes with respect to any or all income tax, social insurance contributions, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable to the Participant or deemed by the Company or the Employer, in its discretion, to be an appropriate charge to the Participant even if legally applicable to the Company or the Employer (“Tax-Related Items”), the ultimate liability for all Tax-Related Items legally due by him or her is and remains the Participant’s responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the RSU award, including the grant, vesting or settlement of the RSUs, the subsequent sale of Shares delivered pursuant thereto and the receipt of cash or any dividends or dividend equivalents; and (2) do not commit to structure the terms of the award or any aspect of the RSUs to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to tax in more than one jurisdiction, the Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction

(b)The Company and/or the Employer, or their respective agents, retain the discretion, and the Participant authorizes the Company and/or the Employer, or their respective agents, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (i) withholding from the Participant’s wages or other cash compensation paid to the Participant by the Company and/or the Employer; (ii) withholding from proceeds of the sale of Shares acquired upon vesting of the RSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent); (iii) requiring the Participant to make a payment in a form acceptable to the Company; (iv) withholding in Shares to be issued upon settlement of the RSUs; or (v) any other method of withholding determined by the Company and to the extent required by applicable law or the Plan, approved by the Committee.

(c)The Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates in the Participant’s jurisdiction(s), to the extent permitted by the Plan. In the event of over-withholding, the Participant may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or if not refunded, the Participant may seek a refund from the local tax authorities. In the event of under-withholding, the Participant may be required to pay any additional Tax-Related Items directly to the applicable tax authority or to the Company and/or the Employer. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes,

- 3 -

the Participant is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items.

(d)Finally, the Participant shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Participant’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Participant fails to comply with the Participant’s obligations with respect to Tax-Related Items.

(e)The Participant represents to the Company that, as of the date hereof, he or she is not aware of any material nonpublic information about the Company or the Common Stock. The Participant and the Company have structured this Agreement to constitute a “binding contract” relating to the sale of Common Stock pursuant to this Section 7, consistent with the affirmative defense to liability under Section 10(b) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) under Rule 10b5-1(c) promulgated under such Act.

8.Nature of Grant. In accepting the grant, the Participant acknowledges that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the Plan;

(b)the grant of the RSUs is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units, or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past;

(c)all decisions with respect to future restricted stock units, if any, will be at the sole discretion of the Company;

(d)the grant of the RSUs and the Participant’s participation in the Plan will not create a right to further employment with the Company or the Employer, as applicable. and shall not interfere with the ability of the Company, the Employer or any parent, subsidiary or affiliate of the Company, as applicable, to terminate Participant’s employment relationship at any time;

(e)the Participant is voluntarily participating in the Plan;

(f)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(h)the future value of the Shares subject to the RSUs is unknown, indeterminable and cannot be predicted with certainty;

(i)unless otherwise agreed with the Company, the RSUs and the Shares subject to the RSUs, and the income and value of same, are not granted as consideration for, or in connection with, any service the Participant may provide as a director of any parent, subsidiary or affiliate of the Company;

(j)the RSUs and the Shares subject to the RSUs, and the income and value of same, are not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, holiday pay, bonuses, long-service awards, leave-related payments, pension, retirement or welfare benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or the Employer;

- 4 -

(k)no claim or entitlement to compensation or damages shall arise from any forfeiture of the RSUs resulting from termination of the Participant’s employment relationship (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or providing services or the terms of the Participant’s employment agreement, if any); and

(l)for purposes of the RSUs, the Participant’s employment relationship will be considered terminated as of the date he or she is no longer actively providing services to the Company, the Employer or any other parent, subsidiary or affiliate of the Company (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or providing services or the terms of his or her employment agreement, if any) and, except in the case of termination due to death or disability or an Eligible Retiree Participant as provided for in Schedule 1, the Participant’s right to vest in the RSUs under the Plan, if any, will terminate effective as of such date and will not be extended by any notice period (e.g., the period of the Participant’s employment service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is employed or providing services or the terms of his or her employment agreement, if any); the Committee shall have the exclusive discretion to determine when the Participant is no longer actively providing services for purposes of his or her RSUs (including whether the Participant may still be considered to be providing services while on a leave of absence).

9.    Data Privacy Information and Consent.

(a)Data Collection and Usage. The Company and the Employer collect, process and use certain personal information about the Participant, including, but not limited to, his or her name, home address, telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all awards granted under the Plan or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in the Participant’s favor (“Data”), for purposes of administering his or her participation in the Plan. The legal basis, where required, for the processing of Data is the Participant’s consent.

(b)Stock Plan Administration Service Providers. The Company transfers Data to Charles Schwab & Co., Inc. and certain of its affiliates (“Charles Schwab”), which is assisting the Company with the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers and share Data with such other provider serving in a similar manner. The Participant may be asked to agree on separate terms and data processing practices with Charles Schwab, with such agreement being a condition to the ability to participate in the Plan.

(c)International Data Transfers. The Company, Charles Schwab and, as the case may be, other service providers of the Company are or might be based in the United States, which means that the Participant’s Data will have to be transferred to or otherwise processed in the United States. The Participant understands and acknowledges that the United States might apply laws not providing a level of protection of his or her Data equivalent to the level of protection in his or her country or jurisdiction. In the absence of appropriate safeguards, the processing of the Participant’s Data in the United States might not be subject to substantive data processing principles or supervision by data protection authorities. In addition, the Participant might not have enforceable rights regarding the processing of his or her Data. By signing or electronically agreeing to this Agreement, the Participant explicitly declares his or her consent to the Company receiving and transferring his or her Data onward to Charles Schwab and, as the case may be, other service providers without implementing appropriate safeguards. Where required, such processing of the Participant’s Data will be exclusively based on his or her consent.

(d)Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, exchange control, labor and securities laws. This period may extend beyond the Participant’s period of employment with the

- 5 -

Employer. When the Company or the Employer no longer need Data for any of the above purposes, they will cease processing it in this context and remove it from all of their systems used for such purposes to the fullest extent practicable.

(e)Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Participant is providing the consents herein on a purely voluntary basis. If the Participant does not consent, or if the Participant later seeks to revoke the consent, his or her salary from or employment with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to grant awards under the Plan or administer or maintain such awards.

(f)Data Subject Rights. The Participant may have a number of rights under data privacy laws in his or her jurisdiction. Depending on where the Participant is based, such rights may include the right to (i) request access to or copies of Data processes, (ii) rectify incorrect Data, (iii) delete Data, (iv) restrict the processing of Data, (v) restrict the portability of Data, (vi) lodge complaints with competent authorities in his or her jurisdiction, and/or (vii) receive a list with the names and addresses of any potential recipients of Data. To receive clarification regarding these rights or to exercise these rights, the Participant can contact his or her local human resources representative.

(g)Other Legal Basis and Additional Consent. The Participant understands that the Company may rely on a different legal basis for the collection, processing or transfer of Data in the future and/or request the Participant to provide another data privacy consent. If applicable, upon request of the Participant or the Employer, he or she will provide a separate executed data privacy agreement (or any other agreements or consents) that the Company and/or the Employer may deem necessary to obtain from the Participant for the purpose of administering his or her participation in the Plan in compliance with the data privacy laws in his or her country, either now or in the future. The Participant understands and agrees that he or she will not be able to participate in the Plan, if he or she fails to provide any such agreement requested by the Company and/or the Employer.

10.Miscellaneous.

(a)No Rights to Employment. The Participant acknowledges and agrees that the vesting of the RSUs pursuant to Section 2 hereof is earned only by continuing service as an employee at the will of the Company (not through the act of being hired or purchasing shares hereunder). The Participant further acknowledges and agrees that the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of continued engagement as an employee or consultant for the vesting period, for any period, or at all.

(b)No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Participant’s participation in the Plan, or his or her acquisition or sale of the Shares subject to the RSUs. The Participant understands and agrees that he or she should consult with his or her own personal tax, legal and financial advisors regarding participation in the Plan before taking any action related to the Plan.

(c)Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, and each other provision of this Agreement shall be severable and enforceable to the extent permitted by law.

(d)Waiver. Any provision for the benefit of the Company contained in this Agreement may be waived, either generally or in any particular instance, by the Board of Directors of the Company.

(e)Binding Effect.

(g)Language. The Participant acknowledges that he or she is sufficiently proficient in English, or has consulted with an advisor who is sufficiently proficient in English, so as to allow the Participant to understand the terms and conditions of this Agreement, including the Appendix. Furthermore, if the Participant has received this Agreement, or any other document related to the RSUs and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

(h)Pronouns. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa.

(i)Entire Agreement; Conflicts and Interpretation. This Agreement, including any special terms and conditions set forth in the Appendix hereto for the Participant’s country, and the Plan, including any applicable Sub-Plan, constitute the entire agreement between the parties, and supersedes all prior agreements and understandings, relating to the subject matter of this Agreement. In the event of any conflict between this Agreement and the Plan, the Plan shall control. In the event of any ambiguity in this Agreement, or any matters as to which this Agreement is silent, the Plan shall govern including, without limitation, the provisions thereof pursuant to which the Board of Directors (or a committee thereof) has the power, among other things, to (i) interpret the Plan, (ii) prescribe, amend and rescind rules and regulations relating to the Plan and (iii) make all other determinations deemed necessary or advisable for the administration of the Plan.

(j)Appendix. The RSUs shall be subject to any additional provisions set forth in the Appendix for the Participant’s country. If the Participant relocates to one of the countries included in the Appendix during the vesting period for the RSUs, the additional provisions for such country shall apply to the Participant to the extent the Company determines that the application of such provisions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement.

(k)Imposition of Other Requirements. The Company reserves the right to impose other requirements on the RSUs and the Shares acquired upon vesting of the RSUs, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

(l)Amendment. The Company may modify, amend or waive the terms of this Agreement prospectively or retroactively, but no such modification, amendment or waiver shall impair the rights of the Participant without his or her consent, except as required by applicable law, Nasdaq or stock exchange rules, tax rules or accounting rules. Any provision for the benefit of the Company contained in this Agreement may be waived, either generally or in any particular instance, by the Board of Directors (or a committee thereof) of the Company. The waiver by either party of compliance with any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by such party or any other participant of a provision of this Agreement.

(m)Governing Law. This Agreement shall be construed, interpreted and enforced in accordance with the internal laws of the U.S. State of Delaware, without regard to any applicable conflicts of laws. For purposes of litigating any dispute that arises under the grant or the Agreement, the parties hereby submit to and consent to the jurisdiction of the U.S. State of Delaware, agree that such litigation shall be conducted in the courts of Delaware, or the federal courts for the United States for the Third District, where this Agreement is made and/or to be performed.

- 7 -

(n)Unfunded Rights. The right of the Participant to receive Common Stock pursuant to this Agreement is an unfunded and unsecured obligation of the Company. The Participant shall have no rights under this Agreement other than those of an unsecured general creditor of the Company.

(o)Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the RSUs awarded under and participation in the Plan or future restricted stock units or other Awards that may be awarded under the Plan by electronic means or to request the Participant’s consent to participate in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

(p)Insider Trading/Market Abuse Laws. The Participant acknowledges that, depending on his or her or his or her broker’s country of residence or where the Shares are listed, the Participant may be subject to insider trading restrictions and/or market abuse laws, which may affect his or her ability to acquire or sell or attempt to sell Shares or rights to Shares (e.g., RSUs), either directly or indirectly, or rights linked to the value of Shares under the Plan during such times as the Participant is considered to have “inside information” regarding the Company (as defined by or determined under the laws in the applicable jurisdiction or the laws in his or her country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Participant placed before he or she possessed inside information. Furthermore, the Participant could be prohibited from (i) disclosing the inside information to any third party and (ii) “tipping” third parties or causing them to otherwise to buy or sell securities. Keep in mind third parties include fellow employees. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Participant acknowledges that it is his or her responsibility to comply with any applicable restrictions, including those imposed under any applicable Company insider trading policy, and the Participant should consult with his or her own personal legal and financial advisors on this matter before taking any action related to the Plan.

(q)Foreign Asset/Account Reporting, Exchange Control and Tax Requirements. The Participant acknowledges that there may be certain foreign asset and/or account reporting requirements and exchange controls which may affect his or her ability to acquire or hold Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends received or sale proceeds arising from the sale of Shares) in a brokerage or bank account outside his or her country. The Participant understands that he or she may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country. The Participant also may be required to repatriate sale proceeds or other funds received as a result of his or her participation in the Plan to his or her country through a designated bank or broker and/or within a certain time after receipt. In addition, the Participant may be subject to tax payment and/or reporting obligations in connection with any income realized under the Plan and/or from the sale of Shares. The Participant acknowledge that it is his or her responsibility to comply with all such requirements, and that he or she should consult his or her personal legal and tax advisors, as applicable, to ensure his or her compliance.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Use of Estimates

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ materially from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these financial statements include, but are not limited to, those related to revenue, accounts receivable and related reserves, valuation and impairment of investments and marketable securities, valuation and useful lives of acquired intangible assets, useful lives and realizability of long-lived assets, capitalized internal-use software development costs, income tax reserves and accounting for stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the date of the change in estimate.

Cash, Cash Equivalents and Marketable Securities

Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase. Marketable securities consist of corporate, government and other securities. Securities having remaining maturities of less than one year from the date of the balance sheet are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets.

The Company classifies its fixed income securities with readily determinable market values as available-for-sale. These investments are classified as marketable securities on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature and reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of income. Gains and losses on investments are calculated on the basis of specific identification.

Marketable securities are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health and business outlook of the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends; and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Assessing the above factors involves inherent uncertainty. Write-downs, if recorded, could be materially different from the actual market performance of marketable securities in the Company’s portfolio if, among other things, relevant information related to the marketable securities was not publicly available or other factors not considered by the Company would have been relevant to the determination of impairment.

Accounts Receivable and Related Reserves

The Company’s accounts receivable balance includes unbilled amounts that represent revenue recorded for customers that are typically billed monthly in arrears. The Company records reserves against its accounts receivable balance which primarily consists of allowances for current expected credit losses. Increases and decreases in the allowance for current expected credit losses are included as a component of general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses has been developed using historical loss rates for the previous twelve months as well as expectations about the future where the Company has been able to develop forecasts to support its estimates. In addition, the allowance considers outstanding balances on a customer-specific, account-by-account basis. The Company assesses collectibility based upon a review of customer receivables from prior sales with collection issues where the Company no longer believes that the customer has the ability to pay for services previously provided. The Company also performs ongoing credit evaluations of its customers. If such an evaluation indicates that payment is no longer reasonably assured for services provided, any future services provided to that customer will result in the creation of a cash-basis reserve until the Company receives consistent payments. The Company does not have any off-balance sheet credit exposure related to its customers.

Incremental Costs to Obtain a Contract with a Customer

The Company capitalizes incremental costs associated with obtaining customer contracts, specifically certain commission and incentive payments. The Company pays commissions and incentives up-front based on contract value upon signing a new arrangement with a customer and upon renewal and upgrades of existing contracts with customers if the renewal and upgrades result in an incremental increase in contract value. To the extent commissions and incentives are earned, the expenses, including estimated payroll taxes, are deferred on the Company's consolidated balance sheet and amortized over the expected life of the customer arrangement on a straight-line basis. Based on the nature of the Company's unique technology and services, and the rate at which the Company continually enhances and updates its technology, the expected life of the customer arrangement is determined to be approximately three years. Additionally, the Company may pay commissions and incentives based upon contract value, rather than incremental increase in contract value, to certain sales groups within the Company. For these commission arrangements, the Company amortizes capitalized costs for contract renewals over an average renewal contract period of 16 months. The Company also incurs commission expense on an ongoing basis based upon revenue recognized. In these cases, no incremental costs are deferred, as the commissions are earned and expensed in the same period for which the associated revenue is recognized.

Amortization of the costs is primarily included in sales and marketing expense in the consolidated statements of income. The current portion of deferred commission and incentive payments is included in prepaid expenses and other current assets, and the long-term portion is included in other assets on the Company's consolidated balance sheets.

Concentrations of Credit Risk

The amounts reflected in the consolidated balance sheets for accounts receivable, other current assets, accounts payable, accrued liabilities and other current liabilities approximate fair values due to their short-term maturities. The Company maintains the majority of its cash, cash equivalents and marketable securities with major financial institutions that the Company believes to be of high credit standing. The Company believes that, as of December 31, 2022, its concentration of credit risk related to cash equivalents and marketable securities was not significant.

Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which the Company makes substantial sales. The Company’s customer base consists of a large number of geographically-dispersed customers diversified across several industries. To reduce risk, the Company routinely assesses the financial strength of its customers. Based on such assessments, the Company believes that its accounts receivable credit risk exposure is limited. For the years ended December 31, 2022, 2021 and 2020, no customer accounted for more than 10% of total revenue. As of December 31, 2022 and 2021, there was one customer with an accounts receivable balance greater than 10% of total accounts receivable. The Company believes that, as of December 31, 2022 and 2021, its concentration of credit risk related to accounts receivable was not significant.

Fair Value of Financial Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company has certain financial assets and liabilities recorded at fair value, principally cash equivalents and short- and long-term marketable securities that have been classified as Level 1, 2 or 3 within the fair value hierarchy. Fair

values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the reporting date. Fair values determined by Level 2 inputs utilize data points other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair values determined by Level 3 inputs are based on unobservable data points for the asset or liability.

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Property and equipment generally include purchases of items with a per-unit value greater than $1,000 and an estimated useful life greater than one year. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the related lease terms or their estimated useful lives.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in income from operations. Repairs and maintenance costs are expensed as incurred.

Operating Leases

The Company enters into operating leases for real estate assets related to office space and co-location assets related to space or racks at co-location facilities and related equipment for its servers and other networking equipment. The Company determines if an arrangement contains a lease at the inception of a contract by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration and the right to obtain the economic benefits from the use of the identified asset.

Upon commencement of a lease, the Company records a right-of-use asset that represents the Company’s right to use the underlying asset for the lease term and a lease liability that represents an obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Lease payments are discounted at the lease commencement date. As the Company’s leases do not provide an implicit rate, an incremental borrowing rate has been applied based on the Company's credit-adjusted risk-free rate.

The Company often enters into contracts that contain both lease and non-lease components. Real estate non-lease components include real estate taxes, insurance, maintenance, parking and other operating costs. Co-location non-lease components include utilities and other operating costs. The Company includes both lease and non-lease components of fixed costs in its lease arrangements as a single lease component. Variable costs, such as utilities based on actual usage, are not included in the measurement of right-of-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs.

The Company’s lease terms often include renewal options and, particularly in the case of co-location arrangements, may include evergreen provisions. The Company’s right-of-use assets and lease liabilities generally do not include the options to extend, or terminate, unless it is reasonably certain that the Company will exercise these options. The Company has elected to exclude leases for certain networking equipment and leases assumed through acquisitions with terms of 12 months or less from its right-of-use assets and lease liabilities on its consolidated balance sheets.

Lease expense is recognized on a straight-line basis over the expected lease term.

Equity Method Investments

The Company accounts for equity investments in which it has significant influence, but not a controlling financial interest, using the equity method of accounting. Under the equity method of accounting, investments are initially recorded at cost, less impairment, and subsequently adjusted to recognize the Company’s share of earnings or losses.

In February 2019, the Company and Mitsubishi UFJ Financial Group ("MUFG") announced the establishment of a joint venture, the Global Open Network, Inc. ("GO-NET"), and their plans to offer a new blockchain-based online payment network. The Company's 20% stake in GO-NET was accounted for using the equity method.

During the first quarter of 2022, MUFG, the majority owner of GO-NET, announced its intention to suspend the operations of GO-NET and to eventually liquidate it. As a result of MUFG's intention to suspend operations, the Company impaired its remaining investment of $7.5 million. The Company recorded a loss of $14.0 million during the year ended December 31,

2021, which reflects its share of the losses incurred by GO-NET during that year. During the year ended December 31, 2020, the Company recorded a loss of $13.1 million, which included an $11.0 million impairment to reduce the Company's investment to its fair value due to a modified business plan and continued negative projected cash flows. The valuation technique used to measure fair value of the Company's equity method investment in GO-NET was primarily an adjusted net asset value model based on labor costs and the amount of time required to develop a similar technology for use in the planned payment processing service.

Subsequent to the establishment of the joint venture, the Company recorded revenue of $4.0 million, $10.1 million, and $11.1 million for the years ended December 31, 2022, 2021 and 2020, respectively, for services provided to GO-NET. The Company no longer provided services after June 30, 2022 due to the intention to suspend operations and to eventually liquidate it.

Goodwill, Acquired Intangible Assets and Long-Lived Assets

Goodwill is the amount by which the cost of acquired net assets in a business combination exceeds the fair value of the net identifiable assets on the date of purchase and is carried at its historical cost. The Company tests goodwill for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company performs its impairment test of goodwill as of December 31 each year. As of December 31, 2022, 2021 and 2020, the Company concluded that it has one reporting unit and that its chief operating decision maker is its chief executive officer and the executive management team. The Company has assigned the entire balance of goodwill to one reporting unit. The fair value of the reporting unit was based on the Company's market capitalization as of each of December 31, 2022 and 2021, and it was substantially in excess of the carrying value of the reporting unit at each date. The fair value of the Company's reporting unit was determined by the Company's enterprise value as of the years ended December 31, 2022, 2021 and 2020.

Acquired intangible assets consist of completed technologies, customer relationships, trademarks and trade names, non-compete agreements and acquired license rights. Acquired intangible assets, other than goodwill, are amortized over their estimated useful lives based upon the estimated economic value derived from the related intangible asset. Significant judgment is used in determining fair values of acquired intangibles assets and their estimated useful lives. Fair value and useful life determinations may be based on, among other factors, estimates of future expected cash flows, royalty cost savings and appropriate discount rates used in calculating present values.

Long-lived assets, including property and equipment, operating lease right-of-use assets and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances, such as service discontinuance, technological obsolescence, significant decreases in the Company’s market capitalization, facility closures or work-force reductions indicate that the carrying amount of the long-lived asset may not be recoverable. When such events occur, the Company compares the carrying amount of the asset to the undiscounted expected future cash flows related to the asset. If this comparison indicates that an impairment is present, the amount of the impairment is calculated as the difference between the carrying amount and the fair value of the asset.

Contract Liabilities

Contract liabilities primarily represent payments received from customers for which the related performance obligations have not yet been satisfied. These balances consist of the unearned portion of monthly service fees and integration fees and prepayments made by customers for future periods. The current and long-term portions of the Company's contract liabilities are included in deferred revenue in the respective sections of the Company's consolidated balance sheets.

Revenue Recognition

The Company primarily derives revenue from the sale of services to customers executing contracts having terms of one year or longer. Services included in the Company's contracts consist of its core services – the delivery of content, applications and software over the internet – as well as security and cloud computing solutions and professional services. Revenue is recognized upon transfer of control of promised services in an amount that reflects the consideration the Company expects to receive in exchange for those services.

The Company enters into contracts that may include various combinations of these services, which are generally capable of being distinct and accounted for as separate performance obligations. These contracts generally commit the customer to a minimum of monthly, quarterly or annual levels of usage and specify the rate at which the customer must pay for actual usage above the stated minimum. Based on the typical structure of the Company's contracts, which are generally for monthly

recurring services that are essentially the same over time and have the same pattern of transfer to the customer, most performance obligations represent a promise to deliver a series of distinct services over time.

The Company's contracts with customers sometimes include promises to deliver multiple services to a customer. Determining whether services are distinct performance obligations often requires the exercise of judgment by management. For example, advanced features that enhance a service and are highly interrelated are generally not considered distinct; rather, they are combined with the service they relate to into one performance obligation. Different determinations related to combining services into performance obligations could result in differences in the timing and amount of revenue recognized in a period.

Generally, the transaction price in a contract is equal to the committed price stated in the contract, less any discounts or rebates. The Company's typical contracts qualify for series accounting, and the pricing terms generally do not require estimation of the transaction price beyond the reporting period. As a result, any incremental fees generated as a result of usage or “bursting” over committed contract levels are recorded in the period to which the services relate. The amount of consideration recognized for usage above contract minimums is limited to the amount the Company expects to be entitled to receive in exchange for providing the services. Once the transaction price has been determined, the Company allocates such price among all performance obligations in the contract on a relative standalone selling price (“SSP”) basis.

Determination of SSP requires the exercise of judgment by management. SSP is based on observable inputs such as the price the Company charges for the service when sold separately or the discounted list price per management’s approved price list. In cases where services are not sold separately or price list rates are not available, a cost-plus-margin approach or adjusted market approach is used to determine SSP.

Most content delivery and security services represent stand-ready obligations that are satisfied over time as the customer simultaneously receives and consumes the benefits provided by the Company. Accordingly, revenue for those services is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any bursting over given commitments is recognized in the period in which the traffic was served. For services that involve traffic consumption, revenue is recognized in an amount that reflects the level of traffic served to a customer in a given period. For custom arrangements, other methods may be used as a measure of progress towards satisfying the performance obligations.

Some of the Company's contracts are satisfied at a point in time, such as one-time professional services, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at the point in time of delivery or satisfaction of the performance obligation.

From time to time, the Company enters into contracts to sell its services or license its technology to unrelated enterprises at or about the same time that it enters into contracts to purchase products or services from the same enterprises. Consideration payable to a customer is reviewed as part of the transaction price. If the payment to the customer does not represent payment for a distinct service, revenue is recognized only up to the net amount of consideration after customer payment obligations are considered. The Company may also resell the licenses or services of third parties. If the Company is acting as an agent in an arrangement with a customer to provide third party services, the transaction price reflects only the net amount to which the Company will be entitled, after accounting for payments made to the third party responsible for satisfying the performance obligation.

Cost of Revenue

Cost of revenue consists primarily of fees paid to network providers for bandwidth and to third-party network data centers for housing servers, also known as co-location costs. Cost of revenue also includes employee costs for services delivery and network operation, build-out and support of the Company's network; network storage costs; cost of software licenses; depreciation of network equipment used to deliver the Company’s services; amortization of network-related internal-use software; and costs for the production of live events streamed by the Company for customers. The Company enters into contracts for bandwidth with third-party network providers with terms typically ranging from several months to five years. These contracts generally commit the Company to pay minimum monthly fees plus additional fees for bandwidth usage above the committed level. In some circumstances, internet service providers (“ISPs”) make rack space available for the Company to locate its servers and provide access to their bandwidth at a discount or no cost. Although the Company does not provide any goods or services to the ISPs or the ISPs’ customers under these arrangements, the ISPs and their customers indirectly benefit by accessing content through a local Company server, resulting in better content delivery. The Company records the cost of these vendor relationships at their negotiated transaction price, which is either at a discount or no cost.

Research and Development Costs and Capitalized Internal-Use Software

Research and development costs consist primarily of payroll and related personnel costs for the design, development, deployment, testing and enhancement of the Company’s services and network. Costs incurred in the development of the Company’s services are expensed as incurred, except certain internal-use software development costs eligible for capitalization.

Capitalized costs include external consulting fees, payroll and payroll-related costs and stock-based compensation for employees in the Company’s development and information technology groups who are directly associated with, and who devote time to, the Company’s internal-use software projects. Capitalization begins when the planning stage is complete and the Company commits resources to the software project; capitalization continues during the application development stage. Capitalization ceases when the software has been tested and is ready for its intended use. Costs incurred during the planning, training and post-implementation stages of the software development life-cycle are expensed as incurred. The Company amortizes completed internal-use software that is used on its network to cost of revenue over its estimated useful life.

Accounting for Stock-Based Compensation

The Company recognizes compensation costs for all stock-based payment awards made to employees based upon the awards’ grant-date fair value. The stock-based payment awards include stock options, restricted stock, restricted stock units, deferred stock units and employee stock purchases related to the Company’s employee stock purchase plan.

For stock options, the Company has selected the Black-Scholes option-pricing model to determine the fair value of stock option awards. For stock awards with market-based vesting conditions, the Company uses a Monte Carlo simulation to determine the fair value of the award. For stock options, restricted stock units and deferred stock units that contain only a service-based vesting feature, the Company recognizes compensation cost on a straight-line basis over the award's vesting period. For awards with a performance condition-based vesting feature, the Company recognizes compensation cost on a graded-vesting basis over the award's expected vesting period, commencing when achievement of the performance condition is deemed probable. In addition, for awards that vest and become exercisable only upon achievement of specified performance conditions, the Company makes judgments and estimates each quarter about the probability that such performance conditions will be met or achieved. Any changes to those estimates that the Company makes from time to time may have a significant impact on the stock-based compensation expense recorded and could materially impact the Company’s results of operations.

Foreign Currency Translation and Forward Currency Contracts

The assets and liabilities of the Company's subsidiaries are translated at the applicable exchange rate as of the balance sheet date, and revenue and expenses are translated at an average rate over the period. Resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss, a separate component of stockholders’ equity. Gains and losses on inter-company and other non-functional currency transactions are recorded in other income (expense), net.

The Company enters into short-term foreign currency forward contracts to offset foreign exchange gains and losses generated by the re-measurement of certain assets and liabilities recorded in non-functional currencies. Changes in the fair value of these derivatives, as well as re-measurement gains and losses, are recognized in current earnings in other income (expense), net. As of December 31, 2022 and 2021, the fair value of the forward currency contracts and the underlying gains and losses for the years ended December 31, 2022, 2021 and 2020 were immaterial.

The Company's foreign currency forward contracts may be exposed to credit risk to the extent that its counterparties are unable to meet the terms of the agreements. The Company seeks to minimize counterparty credit (or repayment) risk by entering into transactions only with major financial institutions of investment grade credit rating.

Income Taxes

The Company's provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated as the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse or the carryforwards are expected to be realized.

    The Company currently has net deferred tax assets consisting of net operating loss (“NOL”) carryforwards, tax credit carryforwards and deductible temporary differences. Management periodically weighs the positive and negative evidence to determine if it is more-likely-than-not that some or all of the deferred tax assets will be realized.

    The Company has recorded certain tax reserves to address potential exposures involving its income tax positions. These potential tax liabilities result from the varying application of statutes, rules, regulations and interpretations by different taxing jurisdictions. The Company's estimate of the value of its tax reserves contains assumptions based on past experiences and judgments about the interpretation of statutes, rules and regulations by taxing jurisdictions. It is possible that the costs of the ultimate tax liability or benefit from these matters may be more or less than the amount the Company estimated.

    Uncertainty in income taxes is recognized in the Company's consolidated financial statements using a two-step process. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained based on technical merit, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement.

Newly-Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board ("FASB") issued guidance that was expected to reduce complexity and improve comparability of financial reporting associated with accounting for convertible instruments and contracts in an entity’s own equity. The Company adopted this guidance on January 1, 2022 on a modified retrospective basis.

The convertible senior notes included on the Company's consolidated balance sheet more closely reflect the principal amounts. Prior to the adoption of this guidance, the Company separated its convertible senior notes into a liability and an equity component. The equity portion is now eliminated. The cumulative effect of the changes was an increase to convertible senior notes of $304.7 million, an increase to deferred income tax liabilities of $0.7 million, an increase to deferred income tax assets of $77.7 million, a decrease to property and equipment of $7.7 million and a decrease to additional paid-in capital of $375.4 million on the consolidated balance sheet. The net effect of these adjustments was recorded as an increase to retained earnings as of January 1, 2022.

Additionally, the new guidance eliminates the use of the treasury stock method for convertible instruments that can be settled in whole or in part with equity, when calculating diluted earnings per share. Instead, it requires application of the if-converted method. Under that method, diluted earnings per share would generally be calculated assuming that all the convertible senior notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. The application of the if-converted method reduces the Company’s reported diluted earnings per share after the adoption date. However, in December 2021, the Company made an irrevocable election to settle the principal portion of the convertible senior notes with cash. Accordingly, the if-converted method is only impacted by any potential shares to be delivered for the amount in excess of the principal portion. The changes to the diluted earnings per share guidance did not materially impact the Company's results of operations.

With the elimination of the debt discount created by the equity component, amortization of the debt discount is eliminated, which decreases interest expense, and therefore increases net income and earnings per share, from the period of adoption. This had the effect of increasing basic and diluted earnings per share for the year ended 2022 by $0.32.

The Company offers certain eligible employees the ability to participate in a non-qualified deferred compensation plan. The mutual funds held by the Company that are associated with this plan are classified as restricted trading securities. These securities are not included in the available-for-sale securities table above but are included in marketable securities in the consolidated balance sheets.

Unrealized gains and unrealized temporary losses on investments classified as available-for-sale are included within accumulated other comprehensive loss in the consolidated balance sheets. Upon realization, those amounts are reclassified from accumulated other comprehensive loss to interest and marketable securities income, net in the consolidated statements of income. As of December 31, 2022, the Company held for investment corporate bonds with a fair value of $835.4 million, which are classified as available-for-sale marketable securities and have been in a continuous unrealized loss position for more than 12 months. The unrealized losses related to these corporate bonds were $31.3 million and are included in accumulated other comprehensive loss as of December 31, 2022. The unrealized losses are attributable to changes in interest rates. Based on the evaluation of available evidence, the Company does not believe any unrealized losses represent other than temporary impairments.

The fair value measurements within the fair value hierarchy of the Company’s financial assets as of December 31, 2022 and 2021 were as follows (in thousands): 

	Total Fair Value		Fair Value Measurements at Reporting Date Using

As of December 31, 2022 and 2021, the Company grouped money market and mutual funds using a Level 1 valuation because market prices for such investments are readily available in active markets. As of December 31, 2022 and 2021, the Company grouped time deposits, commercial paper, U.S. government agency obligations and corporate bonds using a Level 2 valuation because quoted prices for similar assets in active markets (or identical assets in an inactive market) are available. The Company did not have any transfers of assets or liabilities between Level 1 or Level 2 of the fair value measurement hierarchy during the years ended December 31, 2022 and 2021.

When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. When available, the Company uses quoted market prices to measure fair value. The valuation technique used to measure fair value for the Company's Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market-based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about the assumptions market participants would use to estimate the fair value of a financial instrument.

Contractual maturities of the Company’s available-for-sale marketable securities held as of December 31, 2022 and 2021 were as follows (in thousands):

Acquisitions

Acquisitions

Acquisition-related costs were $10.7 million, $13.3 million and $5.6 million during the years ended December 31, 2022, 2021 and 2020, respectively, and are included in general and administrative expense in the consolidated statements of income. Pro forma results of operations for the acquisitions completed in the years ended December 31, 2022, 2021 and 2020 have not been presented because the effects of the acquisitions, individually and in the aggregate, were not material to the Company's consolidated financial results.

2022 Acquisition

Linode

In March 2022, the Company acquired all the outstanding equity interests of Linode Limited Liability Company ("Linode") for $898.5 million in cash. Linode is an infrastructure-as-a-service platform provider that allows for developer-friendly cloud computing capabilities. The acquisition is intended to enhance the Company’s computing services by enabling it to create a unique cloud platform to build, run and secure applications from the cloud to the edge. Revenue attributable to Linode since the date of the acquisition, included in the Company's consolidated statements of income, for 2022 was $103.5 million. Earnings included in the Company's consolidated statements of income since the date of the acquisition are not material.

The preliminary allocation of the purchase price for Linode was as follows (in thousands):

Total purchase consideration	$	898,516
Allocation of the purchase consideration:
Cash	$	26,678
Accounts receivable	7,171
Prepaid expenses and other current assets	4,478
Property and equipment	56,268
Operating lease right-of-use assets	17,000
Identifiable intangible assets	196,020
Goodwill	617,292
Deferred income tax assets	2,528
Other assets	292
Total assets acquired	927,727
Accounts payable	(5,767)
Accrued expenses	(1,958)
Operating lease liabilities	(17,235)
Other liabilities	(4,251)
Total liabilities assumed	(29,211)
Net assets acquired	$	898,516

As of December 31, 2022, the purchase price allocation was substantially complete except for the finalization of certain income tax matters. Measurement period adjustments to goodwill recognized during 2022 related to the acquisition of Linode were $28.9 million and primarily related to property and equipment and intangible asset adjustments. These measurement period adjustments did not have a material effect on the Company's results of operations.

The value of the goodwill can be attributed to a number of business factors, including a trained technical workforce and cost synergies expected to be realized. The Company expects that all of the goodwill related to the acquisition of Linode will be deductible for tax purposes.

Identified intangible assets acquired and their respective weighted average useful lives were as follows (in thousands, except years):

	Gross Carrying Amount		Weighted Average Useful Life (in years)
Customer-related intangible assets	$	84,200	16.8
Completed technologies	70,900		5.8
Acquired license rights	34,320		15.0
Trademarks and trade name	6,600		8.8
Total	$	196,020

The Company applied the relief-from-royalty method to estimate the fair values of the completed technologies and trademarks and the multi-period excess earnings method under the income approach to estimate the fair values of the customer-related acquired intangible assets. The Company applied significant judgment in estimating the fair values of the acquired intangible assets, which involved significant estimates and assumptions with respect to forecasted revenue growth rates, cost of revenue, operating expenses, contributory asset charges and discount rates. The Company used readily available market data to estimate the fair values of the acquired license rights. The total weighted average amortization period for the intangible assets acquired from Linode is 12.2 years. The intangible assets are being amortized based upon the pattern in which the economic benefits of the intangible assets are being utilized.

2021 Acquisitions

Guardicore

In October 2021, the Company acquired all the outstanding equity interests of Guardicore Ltd. ("Guardicore"), for $610.7 million in cash. Guardicore's micro-segmentation solution is designed to limit user access to only those applications that are authorized to communicate with each other, thereby limiting the spread of malware and protecting the flow of enterprise data across the network. The acquisition is intended to enhance the Company's security portfolio with the addition of Guardicore's micro-segmentation technology. Revenue and earnings attributable to acquired operations since the date of acquisition are included in the Company's consolidated statements of income and not presented separately because they are not material. The Company finalized its allocation of the purchase price in the fourth quarter of 2022.

Identified intangible assets acquired and their respective weighted average useful lives were as follows (in thousands, except years):

	Gross Carrying Amount		Weighted Average Useful Life (in years)
Completed technologies	$	79,000	15.0
Customer-related intangible assets	44,200		14.0
Trademarks	400		1.9
Total	$	123,600

The Company applied the relief-from-royalty method to estimate the fair values of the completed technologies and trademarks, and the excess earnings method to estimate the fair values of the customer-related acquired intangible assets. The Company applied significant judgment in estimating the fair values of the acquired intangible assets, which involved significant estimates and assumptions with respect to forecasted revenue growth rates and discount rates. The total weighted average

amortization period for the intangible assets acquired from Guardicore is 14.6 years. The intangible assets are being amortized based upon the pattern in which the economic benefits of the intangible assets are being utilized.

Inverse

The Company allocated $10.7 million of the cost of the acquisition to goodwill and $7.6 million to a technology-related identifiable intangible asset with an average useful life of 14.0 years. The acquired goodwill and intangible assets are partially offset by acquired negative working capital balances. The value of the goodwill is primarily attributable to synergies related to the integration of Inverse technology onto the Company's platform as well as a trained technical workforce. The total amount of goodwill related to the acquisition of Inverse expected to be deductible for tax purposes is $10.7 million.

Restructuring

As a result of MUFG's intention to suspend operations, the Company recorded as a restructuring charge an impairment of $7.5 million during the year ended December 31, 2022, primarily related to certain capitalized internal-use software assets that will no longer be used in operations or will not generate sufficient future cash flows to support their values. The Company does not expect to incur material additional charges related to this action.

Additionally, the Company launched its FlexBase program in May 2022, which is a flexible workspace arrangement that allows employees to choose to work from their home office, a Company office or a combination of both. This is a significant change to the way employees worked prior to the program, and prior to office shutdowns as part of the COVID-19 pandemic. Planning for the program commenced in 2021, and in the fourth quarter of 2021, the Company began to identify certain facilities that were no longer needed. As a result, impairments of right-of-use assets and leasehold improvements were recognized. The Company has incurred expenses of $3.6 million and $3.8 million during the years ended December 31, 2022 and 2021, respectively, related to this action. Management is still evaluating the Company's office utilization, and additional charges related to such type of action may occur in 2023.

During the fourth quarter of 2020, management committed to an action to restructure certain parts of the Company to better position itself to become more agile in delivering its solutions. As a result, certain headcount reductions were necessary and certain capitalized internal-use software charges were realized for software not yet placed into service that will not be completed and implemented due to this action. The Company has incurred expenses of $7.9 million and $23.6 million during

the years ended December 31, 2021 and 2020, respectively, related to this action. The Company does not expect to incur any additional charges related to this action.

The Company also recognizes restructuring charges for redundant employees, facilities and contracts associated with completed acquisitions. Restructuring charges related to acquisitions were not material in any of the years ended December 31, 2022, 2021 and 2020.

Convertible Senior Notes – Due 2027

In August 2019, the Company issued $1,150.0 million in par value of convertible senior notes due 2027 (the "2027 Notes"). The 2027 Notes are senior unsecured obligations of the Company, bear regular interest of 0.375%, payable semi-annually in arrears on March 1 and September 1 of each year, and mature on September 1, 2027, unless repurchased or converted in accordance with their terms prior to maturity.

Each $1,000 principal amount of the notes will be convertible into 8.6073 shares of the Company's common stock, which is equivalent to a conversion price of approximately $116.18 per share, subject to adjustments in certain events. At their option, holders may convert their 2027 Notes prior to the close of business on the business day immediately preceding May 1, 2027, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ended December 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of 2027 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or

•upon the occurrence of specified corporate events.

On or after May 1, 2027, holders may convert all or any portion of their 2027 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

In December 2021, the Company made an irrevocable election to settle the principal amount of the 2027 Notes only in cash. Accordingly, upon conversion, the Company will pay the principal amount in cash and will pay, or deliver, as the case may be, any amount in excess of the principal amount in cash, shares of common stock or a combination of cash and shares of the Company stock, at the Company's election. Prior to this election, upon conversion, the Company, could have elected to deliver to holders cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock for the principal amount.

Prior to January 1, 2022, in accounting for the issuance of the 2027 Notes, the Company separated the 2027 Notes into liability and equity components. The carrying cost of the liability component was calculated by measuring the fair value of a similar debt obligation that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2027 Notes. The difference between the principal amount of the 2027 Notes and the proceeds allocated to the liability component (“debt discount”) is amortized to interest expense using the effective interest method over the term of the 2027 Notes. The equity component is recorded in additional paid-in capital in the consolidated balance sheet to meet the conditions for equity classification. On January 1, 2022, the Company adopted the new guidance for accounting for convertible instruments, which eliminated the equity component. Refer to Note 2 to the consolidated financial statements included elsewhere in this report for details on the new guidance for accounting for convertible instruments.

Initially, the Company allocated the total transaction costs incurred to the liability and equity components based on their relative values. However, subsequent to the adoption of the new guidance for accounting for convertible instruments, all transaction costs are presented as a reduction to the 2027 Notes. Prior to January 1, 2022, transaction costs attributable to the liability component were being amortized to interest expense over the term of the 2027 Notes, and subsequent to the adoption of the new guidance, all transaction costs are being amortized to interest expense over the term of the 2027 Notes.

The 2027 Notes consisted of the following components as of December 31, 2022 and 2021 (in thousands):

	December 31, 2022		December 31, 2021
Liability component:
Principal	$	1,150,000	$	1,150,000
Less: debt discount and issuance costs, net of amortization	(8,707)		(169,030)
Net carrying amount	$	1,141,293	$	980,970
Equity component:	$	—	$	220,529

The estimated fair value of the 2027 Notes at December 31, 2022 and 2021 was $1,111.0 million and $1,359.3 million, respectively. The fair value was determined based on the quoted price of the 2027 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy. Based on the closing price of the Company's common stock of $84.30 on December 31, 2022, the value of the 2027 Notes if converted to common stock was less than the principal amount of $1,150.0 million.

The Company used $100.0 million of the proceeds from the offering to repurchase shares of its common stock, concurrent with the issuance of the 2027 Notes. The repurchase was made in accordance with a share repurchase program previously approved by the board of directors. Additionally, $127.1 million of the proceeds was used for the net cost of the convertible note hedge and warrant transactions. The remaining net proceeds are intended to be used for share repurchases, working capital and general corporate purposes, including potential acquisitions and other strategic transactions.

To minimize the impact of potential dilution upon conversion of the 2027 Notes, the Company entered into convertible note hedge transactions with respect to its common stock in August 2019. The Company paid $312.2 million for the note hedge transactions. The note hedge transactions cover approximately 9.9 million shares of the Company’s common stock at a strike price that corresponds to the initial conversion price of the 2027 Notes, also subject to adjustment, and are exercisable upon conversion of the 2027 Notes. The Company determined that the note hedge meets the definition of a derivative and is classified in stockholders’ equity, as the note hedge is indexed to the Company's common stock, and the Company, at its election, may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock. The Company recorded the purchase of the hedge as a decrease to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the note hedge in its consolidated financial statements.

Warrants

Separately, in August 2019, the Company entered into warrant transactions, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, up to 9.9 million shares of the Company’s common stock at a strike price of approximately $178.74 per share. The Company received aggregate proceeds of $185.2 million from the sale of the warrants. The convertible note hedge and warrant transactions will generally have the effect of increasing the conversion price of the 2027 Notes to approximately $178.74 per share. The Company determined that the warrants meet the definition of a derivative and are classified in stockholders’ equity, as the warrants are indexed to the Company's common stock, and the Company, at its election, may pay or deliver to holders cash or shares of the Company's common stock. The Company recorded the proceeds from issuance of the warrants as an increase to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the warrants in its consolidated financial statements.

Convertible Senior Notes – Due 2025

In May 2018, the Company issued $1,150.0 million in par value of convertible senior notes due 2025 (the "2025 Notes"). The 2025 Notes are senior unsecured obligations of the Company, bear regular interest of 0.125%, payable semi-annually on May 1 and November 1 of each year, and mature on May 1, 2025, unless repurchased or converted prior to maturity.

Each $1,000 principal amount of the notes will be convertible into 10.5150 shares of the Company's common stock, which is equivalent to a conversion price of approximately $95.10 per share, subject to adjustments in certain events. At their option, holders may convert their 2025 Notes prior to the close of business on the business day immediately preceding January 1, 2025, only under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ended June 30, 2018 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; or

•upon the occurrence of specified corporate events.

On or after January 1, 2025, holders may convert all or any portion of their 2025 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date, regardless of the foregoing circumstances.

In December 2021, the Company made an irrevocable election to settle the principal amount of the 2025 Notes only in cash. Accordingly, upon conversion, the Company will pay the principal amount in cash and will pay, or deliver, as the case may be, any amount in excess of the principal amount in cash, shares of common stock or a combination of cash and shares of the Company stock, at the Company's election. Prior to this election, upon conversion, the Company, could have elected to deliver to holders cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock for the principal amount.

Prior to January 1, 2022, in accounting for the issuance of the 2025 Notes, the Company separated the 2025 Notes into liability and equity components. The carrying cost of the liability component was calculated by measuring the fair value of a similar debt obligation that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2025 Notes. The difference between the principal amount of the 2025 Notes and the proceeds allocated to the liability component (“debt discount”) is amortized to interest expense using the effective interest method over the term of the 2025 Notes. The equity component is recorded in additional paid-in capital in the consolidated balance sheet to meet the conditions for equity classification. On January 1, 2022, the Company adopted the new guidance for accounting for convertible instruments, which eliminated the equity component. Refer to Note 2 to the consolidated financial statements included elsewhere in this report for details on the new guidance for accounting for convertible instruments.

Initially, the Company allocated the total transaction costs incurred to the liability and equity components based on their relative values. However, subsequent to the adoption of the new guidance for accounting for convertible instruments, all transaction costs are presented as a reduction to the 2025 Notes. Prior to January 1, 2022, transaction costs attributable to the liability component were being amortized to interest expense over the term of the 2025 Notes, and subsequent to the adoption of the new guidance, all transaction costs are being amortized to interest expense over the term of the 2025 Notes.

The 2025 Notes consisted of the following components as of December 31, 2022 and 2021 (in thousands):

	December 31, 2022		December 31, 2021
Liability component:
Principal	$	1,150,000	$	1,150,000
Less: debt discount and issuance costs, net of amortization	(6,035)		(154,803)
Net carrying amount	$	1,143,965	$	995,197
Equity component:	$	—	$	285,225

The estimated fair value of the 2025 Notes at December 31, 2022 and 2021 was $1,209.1 million and $1,510.4 million, respectively. The fair value was determined based on the quoted price of the 2025 Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 within the fair value hierarchy. Based on the closing price of the Company's common stock of $84.30 on December 31, 2022, the value of the 2025 Notes if converted to common stock was less than the principal amount of $1,150.0 million.

The Company used $46.2 million of the proceeds from the offering to repurchase shares of its common stock, concurrent with the issuance of the 2025 Notes. The repurchase was made in accordance with a share repurchase program previously approved by the board of directors. Additionally, $141.8 million of the proceeds was used for the net cost of convertible note hedge and warrant transactions. The Company also used a portion of the net proceeds to repay at maturity $690.0 million in par value of convertible senior notes due in 2019. The remaining net proceeds are intended to be used for share repurchases, working capital and general corporate purposes, including potential acquisitions and other strategic transactions.

Note Hedge

To minimize the impact of potential dilution upon conversion of the 2025 Notes, the Company entered into convertible note hedge transactions with respect to its common stock in May 2018. The Company paid $261.7 million for the note hedge transactions. The note hedge transactions cover approximately 12.1 million shares of the Company’s common stock at a strike price that corresponds to the initial conversion price of the 2025 Notes, also subject to adjustment, and are exercisable upon conversion of the 2025 Notes. The Company determined that the note hedge meets the definition of a derivative and is classified in stockholders’ equity, as the note hedge is indexed to the Company's common stock, and the Company, at its election, may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock. The Company recorded the purchase of the hedge as a decrease to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the note hedge in its consolidated financial statements.

Warrants

Separately, in May 2018, the Company entered into warrant transactions, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, up to 12.1 million shares of the Company’s common stock at a strike price of approximately $149.18 per share. The Company received aggregate proceeds of $119.9 million from the sale of the warrants. The convertible note hedge and warrant transactions will generally have the effect of increasing the conversion price of the 2025 Notes to approximately $149.18 per share. The Company determined that the warrants meet the definition of a derivative and are classified in stockholders’ equity, as the warrants are indexed to the Company's common stock, and the Company, at its election, may pay or deliver to holders cash or shares of the Company's common stock. The Company recorded the proceeds from issuance of the warrants as an increase to additional paid-in capital. The Company does not recognize subsequent changes in fair value of the warrants in its consolidated financial statements.

Revolving Credit Facility

In May 2018, the Company entered into a $500.0 million five-year, revolving credit agreement (the “2018 Credit Agreement”). Borrowings under the 2018 Credit Agreement bore interest, at the Company's option, at a base rate plus a spread of 0.00% to 0.25% or an adjusted LIBOR rate plus a spread of 0.875% to 1.25%, in each case with such spread being determined based on the Company's consolidated leverage ratio specified in the 2018 Credit Agreement. Regardless of what amounts, if any, outstanding under the 2018 Credit Agreement, the Company was also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.075% to 0.15%, with such rate being based on the Company's consolidated leverage ratio specified in the 2018 Credit Agreement.

In November 2022, the Company entered into a $500.0 million five-year, revolving credit agreement (the “2022 Credit Agreement”). The 2022 Credit Agreement replaces the 2018 Credit Agreement. Borrowings under the 2022 Credit Agreement may be used to finance working capital needs and for general corporate purposes. The 2022 Credit Agreement provides for an initial $500.0 million in revolving loans. Under specified circumstances, the facility can be increased to up to $1.0 billion in aggregate principal amount. The 2022 Credit Agreement expires, and any amounts outstanding thereunder will become due and payable, on November 22, 2027, subject to up to two one-year extensions at the Company's request and with the consent of the lenders party thereto.

Borrowings under the 2022 Credit Agreement bear interest, at the Company's option, and subject to a credit spread adjustment, at a term benchmark rate plus a spread of 0.75% to 1.125%, a reference rate plus a spread of 0.75% to 1.125%, or a base rate plus a spread of 0.00% to 0.125%, in each case with such spread being determined based on the Company's consolidated leverage ratio specified in the 2022 Credit Agreement. Regardless of what amounts, if any, are outstanding under the 2022 Credit Agreement, the Company is also obligated to pay an ongoing commitment fee on undrawn amounts at a rate of 0.07% to 0.125%, with such rate being based on the Company's consolidated leverage ratio specified in the 2022 Credit Agreement.

The 2022 Credit Agreement contains customary representations and warranties, affirmative and negative covenants and events of default. The negative covenants include restrictions on subsidiary indebtedness, liens and fundamental changes. These covenants are subject to a number of important exceptions and qualifications. The principal financial covenant requires a maximum consolidated leverage ratio. There were no outstanding borrowings under the 2022 Credit Agreement as of December 31, 2022. 

Interest Expense

The 2027 Notes bear interest at a fixed rate of 0.375%, with interest is payable semi-annually on March 1 and September 1 of each year. The 2025 Notes bear interest at a fixed rate of 0.125%, with interest is payable semi-annually on May 1 and November 1 of each year. The Company is also obligated to pay ongoing commitment fees under the terms of its credit agreements, in addition to interest payable on outstanding borrowings. Prior to the adoption of the new guidance for accounting for convertible instruments on January 1, 2022, the Company also amortized as interest expense the value of debt discounts of the 2027 Notes and the 2025 Notes. Interest expense included in the consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands):

Legal Matters

The Company is party to various litigation matters that management considers routine and incidental to its business. Management does not expect the results of any of these routine actions to have a material effect on the Company’s business, results of operations, financial condition or cash flows.

Indemnification

The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company agrees to indemnify, hold harmless and reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company's business partners, vendors or customers, in connection with its provision of its services. Generally, these obligations are limited to claims relating to infringement of a patent, copyright or other intellectual property right or the Company’s negligence, willful misconduct or violation of law. Subject to applicable statutes of limitation, the term of each of these indemnification agreements is generally perpetual from the time of execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company carries insurance that covers certain third-party claims relating to its services and activities and that could limit the Company’s exposure in that respect.

The Company has agreed to indemnify each of its officers and directors, or employees who serve as officers or directors of its subsidiaries at management's request, during his or her lifetime for certain events or occurrences that happen by reason of the fact that the officer or director is or was or has agreed to serve as an officer or director of the Company. The Company has director and officer insurance policies that may limit its exposure and may enable the Company to recover a portion of certain future amounts paid.

To date, the Company has not encountered material costs as a result of such indemnification obligations and has not accrued any related liabilities in its financial statements. In assessing whether to establish an accrual, the Company considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

In October 2021, the board of directors authorized a new $1.8 billion share repurchase program, effective January 2022 through December 2024. The Company's goals for the share repurchase programs are to offset the dilution created by its employee equity compensation programs over time and provide the flexibility to return capital to shareholders as business and market conditions warrant, while still preserving its ability to pursue other strategic opportunities.

During the years ended December 31, 2022, 2021 and 2020, the Company repurchased 6.4 million, 4.7 million and 2.0 million shares, respectively, of its common stock for $608.0 million, $522.3 million and $193.6 million, respectively, pursuant to the repurchase programs described above. As of December 31, 2022, the Company had $1.2 billion available for future purchases of shares under the current repurchase program.

The board of directors authorized the retirement of all the outstanding shares of its treasury stock as of each of December 31, 2022, 2021 and 2020.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with Customers

The Company sells its services through a sales force located both domestically and abroad. Revenue derived from operations outside of the U.S. is determined based on the country in which the sale originated. Other than the U.S., no single country accounted for 10% or more of the Company’s total revenue for any reported period. Revenue by geography included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands):

	2022		2021		2020

Total revenue	$	3,616,654	$	3,461,223	$	3,198,149

The Company reports its revenue in three solution categories: security, delivery and compute. Prior to January 1, 2022, revenue by solution was reported by product group: Security Technology Group and Edge Technology Group. Revenue from security solutions was previously presented as Security Technology Group revenue and revenue from delivery and compute solutions was previously presented as Edge Technology Group revenue. The periods presented prior to January 1, 2022 have been revised to reflect this new presentation. Security includes solutions that are designed to protect business online by keeping infrastructure, websites, applications and users safe. Delivery includes solutions that are designed to enable business online, including media delivery and web performance. Compute includes cloud computing, edge applications, cloud optimization and storage. Revenue by solution category included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands):

	2022		2021		2020
Security	$	1,541,941	$	1,334,836	$	1,061,622
Delivery	1,669,257		1,873,243		1,929,810

Total revenue	$	3,616,654	$	3,461,223	$	3,198,149

Most security, delivery and compute services represent obligations that are satisfied over time as the customer simultaneously receives and consumes the services provided by the Company. Accordingly, the majority of the Company's revenue is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any usage over a given commitment is recognized in the period in which the units are served. A small percentage of the Company's contracts are satisfied at a point in time, such as one-time professional services contracts, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at a point in time of delivery or satisfaction of the performance obligation.

During the years ended December 31, 2022, 2021 and 2020, the Company recognized $105.1 million, $78.8 million and $69.9 million of revenue that was included in deferred revenue as of December 31, 2021, 2020 and 2019, respectively.

As of December 31, 2022, the aggregate amount of remaining performance obligations from contracts with customers was $3.5 billion. The Company expects to recognize approximately 65% of its remaining performance obligations as revenue over the next 12 months, with the remainder recognized thereafter. Remaining performance obligations represent the amount of the transaction price under contracts with customers that are attributable to performance obligations that are unsatisfied or partially satisfied at the reporting date. This consists of future committed revenue for monthly, quarterly or annual periods within current contracts with customers, as well as deferred revenue arising from consideration invoiced in prior periods for which the related performance obligations have not been satisfied. It excludes estimates of variable consideration such as usage-based contracts with no committed contract as well as anticipated renewed contracts. Revenue recognized during the years ended December 31, 2022, 2021 and 2020, related to performance obligations satisfied in previous periods was not material.

Equity Plans

In May 2013, the Company's stockholders approved the Akamai Technologies, Inc. 2013 Stock Incentive Plan, which was amended with Company shareholder approval in each of 2015, 2017 and 2019 and was amended and restated with Company shareholder approval in each of 2021 and 2022 (as amended and restated, the "2013 Plan"). The 2013 Plan replaced the Akamai Technologies, Inc. 2009 Stock Incentive Plan (the "2009 Plan"), which in turn replaced the Akamai Technologies, Inc. 2006 Stock Incentive Plan, the Akamai Technologies, Inc. 2001 Stock Incentive Plan and the Akamai Technologies, Inc. 1998 Stock Incentive Plan (such plans, together with the 2009 Plan, the "Previous Plans"). The Company no longer issues equity awards under the Previous Plans, and they solely exist to satisfy outstanding equity awards previously granted under those plans. The 2013 Plan allows for the issuance of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards and cash-based awards for up to 26.5 million shares of common stock, subject to certain adjustments, to employees, officers, directors, consultants and advisers of the Company. Additionally, the Company may grant up to 3.8 million shares of common stock thereunder that were available for grant under the 2009 Plan immediately prior to stockholder approval of the 2013 Plan. Any shares of common stock that are currently outstanding under the Previous Plans that are terminated, canceled, surrendered or forfeited will become available to grant under the 2013 Plan. As of December 31, 2022, the Company had reserved 6.2 million shares of common stock available for future issuance of equity awards under the 2013 Plan.

The Company has assumed certain stock incentive plans and the outstanding stock incentives of companies that it has acquired (“Assumed Plans”). Stock incentive awards outstanding as of the date of acquisition under the Assumed Plans were exchanged for the Company’s stock incentive awards and adjusted to reflect the appropriate conversion ratio as specified by the applicable acquisition agreement, but are otherwise administered in accordance with the terms of the Assumed Plans. Stock incentive awards under the Assumed Plans generally vest over three years to four years, and outstanding stock options under the Assumed Plans expire ten years from the date of grant.

The 1999 Employee Stock Purchase Plan ("1999 ESPP") permits eligible employees to purchase up to 1.5 million shares each June 1 and December 1, provided that the aggregate number of shares issued shall not exceed 20.0 million. The 1999 ESPP allows participants to purchase shares of common stock at a 15% discount from the fair market value of the stock as determined on specific dates at six-month intervals. During the years ended December 31, 2022, 2021 and 2020, the Company issued 0.7 million, 0.6 million and 0.7 million shares under the 1999 ESPP, respectively, with a weighted average purchase price per share of $82.83, $92.05 and $80.71, respectively. Total cash proceeds from the purchase of shares under the 1999 ESPP in the years ended December 31, 2022, 2021 and 2020 were $56.6 million, $59.7 million and $58.4 million, respectively. As of December 31, 2022, approximately $5.8 million had been withheld from employees for future purchases under the 1999 ESPP.

Stock-Based Compensation Expense

Components of total stock-based compensation expense included in the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

	2022		2021		2020
Cost of revenue	$	28,354	$	27,143	$	24,829
Research and development	78,116		65,950		48,855
Sales and marketing	47,789		46,342		65,257
General and administrative	62,926		63,324		58,470
Total stock-based compensation	217,185		202,759		197,411
Provision for income taxes	(46,829)		(56,084)		(62,153)
Total stock-based compensation, net of taxes	$	170,356	$	146,675	$	135,258

In addition to the amounts of stock-based compensation reported in the table above, the Company’s consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 also include stock-based compensation reflected as a component of amortization primarily consisting of capitalized internal-use software; the additional stock-based compensation was $31.3 million, $32.4 million and $29.6 million, respectively, before taxes.

The Company uses the Black-Scholes option pricing model to determine the fair value of the Company’s stock option awards. This model requires the input of subjective assumptions, including expected stock price volatility and the estimated term of each award. The estimated fair value of the Company's stock-based awards, less expected forfeitures, is amortized over the awards’ vesting period on a straight-line basis. Expected volatilities are based on the Company’s historical stock price volatility and implied volatility from traded options in its stock. The Company uses historical data to estimate the expected term of options granted within the valuation model. The risk-free interest rate for periods commensurate with the expected term of the option is based on the U.S. Treasury yield rate in effect at the time of grant. The expected dividend yield is zero, as the Company currently does not pay a dividend and does not anticipate doing so in the future.

The grant-date fair values of awards granted under the 1999 ESPP during the years ended December 31, 2022, 2021 and 2020 were estimated using the Black-Scholes option pricing model with the following weighted-average assumptions:

	2022		2021		2020
Expected term (in years)	0.5		0.5		0.5
Risk-free interest rate	1.9	%	0.1	%	0.7	%
Expected volatility	26.0	%	32.2	%	30.4	%
Dividend yield	—	%	—	%	—	%

For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of awards granted under the 1999 ESPP was $33.26 per share, $36.17 per share and $32.30 per share, respectively.

As of December 31, 2022, total pre-tax unrecognized compensation cost for stock options, restricted stock units, deferred stock units and shares of common stock issued under the 1999 ESPP was $399.3 million. The expense is expected to be recognized through 2025 over a weighted average period of 2.0 years.

Stock Options

Stock option activity during the year ended December 31, 2022 was as follows:

	Shares (in thousands)	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at January 1, 2022	1	$	41.08
Exercised	—	40.44
Outstanding at December 31, 2022	1	$	41.28	0.6	$	43
Exercisable at December 31, 2022	1	$	41.28	0.6	$	43
Vested or expected to vest December 31, 2022	1	$	41.28	0.6	$	43

The total pre-tax intrinsic value of options exercised during the year ended December 31, 2022 was insignificant. The total pre-tax intrinsic value of options exercised during the years ended December 31, 2021 and 2020 were $0.6 million and $1.0 million, respectively. No options vested during the years ended December 31, 2022, 2021 and 2020.

The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $84.30 on December 31, 2022, that would have been received by the option holders had all option holders exercised their “in-the-money” options as of that date. The total number of shares issuable upon the exercise of “in-the-money” options exercisable as of December 31, 2022 was 1,002.

Deferred Stock Units

The Company has granted deferred stock units ("DSUs") to non-employee members of its board of directors. Each DSU represents the right to receive one share of the Company’s common stock upon vesting. The holder may elect to defer receipt of the vested shares of stock represented by the DSU for a period of at least one year but not more than ten years from the grant date. DSUs vest 100% on the first anniversary of the grant date. If a director has completed one year of service, vesting of 100% of the DSUs held by such director will accelerate at the time of his or her departure from the board.

DSU activity for the year ended December 31, 2022 was as follows:

	Units (in thousands)	Weighted Average Grant Date Fair Value
Outstanding at January 1, 2022	98	$	72.96
Granted	27	97.40
Vested and distributed	(45)	73.33
Outstanding at December 31, 2022	80	$	81.11

The total pre-tax intrinsic value of DSUs that were vested and distributed during the years ended December 31, 2022, 2021 and 2020 was $4.9 million, $4.1 million and $0.9 million, respectively. The total fair value of DSUs that were vested and distributed during the years ended December 31, 2022, 2021 and 2020 was $3.3 million, $2.7 million and $0.7 million, respectively. The grant-date fair value is calculated based upon the Company’s closing stock price on the date of grant. For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of DSU awards granted was $97.40 per share, $114.56 per share and $100.58 per share, respectively. As of December 31, 2022, 27,306 DSUs were unvested, with an aggregate intrinsic value of approximately $2.3 million and a weighted average remaining contractual life of approximately 0.4 years. These units are expected to vest in May 2023.

Restricted Stock and Restricted Stock Units

Different types of restricted stock units ("RSUs") granted by the Company during the year ended December 31, 2022 were as follows (in thousands):

	December 31, 2022
RSUs with service-based vesting conditions	3,243
RSUs with market-based vesting conditions	81
RSUs with performance-based vesting conditions	239
Total	3,563

RSUs represent the right to receive one share of the Company’s common stock upon vesting. RSUs are granted at the discretion of the board of directors, a committee thereof or, subject to defined limitations, the Chief Executive Officer of the Company, acting as a committee of one director, to whom such authority has been delegated. The Company has issued RSUs that vest based on the passage of time assuming continued service with the Company, RSUs that vest based upon total shareholder return ("TSR") measured against the benchmark TSR of a peer group and RSUs that vest only upon the achievement of defined performance metrics tied primarily to revenue and earnings targets.

For RSUs with service-based vesting conditions, the fair value is calculated based upon the Company’s closing stock price on the date of grant, and the stock-based compensation expense is being recognized over the vesting period. Most RSUs with service-based vesting provisions vest in installments over a three- or four-year period following the grant date.

The Company uses the Monte Carlo simulation model to determine the fair value of the Company's RSUs based on TSR. This model requires the input of assumptions, including the estimated term of each award, the risk-free interest rate, historical stock price volatility of the Company's shares and historical stock price volatility of peer-company shares. The grant-date fair values of the TSR-based RSUs granted during the years ended December 31, 2022, 2021 and 2020 were estimated using a Monte Carlo simulation model with the following assumptions:

	2022		2021		2020
Expected term (in years)	3.0		3.0		3.0
Risk-free interest rate	1.7	%	0.3	%	0.7	%
Akamai historical share price volatility	30.3	%	32.7	%	28.2	%
Average volatility of peer-company share price	40.7	%	39.6	%	28.9	%

For the years ended December 31, 2022, 2021 and 2020, management measured compensation expense for performance-based RSUs based upon a review of the Company’s expected achievement against specified financial performance targets. Such compensation cost is being recorded using a graded-vesting method for each series of grants of performance-based RSUs, to the extent management has deemed that such awards are probable of vesting based upon the expected achievement against the specified targets. On a periodic basis, management reviews the Company’s expected performance and adjusts the compensation cost, if needed, at such time.

RSU activity for the year ended December 31, 2022 was as follows:

	Units (in thousands)	Weighted Average Grant Date Fair Value
Outstanding at January 1, 2022	4,389	$	95.75
Granted	3,563	107.17
Vested	(2,096)	110.57
Forfeited	(578)	102.92
Outstanding at December 31, 2022	5,278	$	121.92

The shares granted during 2022 and presented in the table above include 172,271 RSUs assumed by the Company as a result of the acquisition of Linode.The total pre-tax intrinsic value of RSUs that vested during the years ended December 31, 2022, 2021 and 2020 was $227.1 million, $226.4 million and $192.5 million, respectively. The total fair value of RSUs that vested during the years ended December 31, 2022, 2021 and 2020 was $231.7 million, $233.0 million and $198.9 million, respectively. The grant-date fair value of each RSU is calculated based upon the Company’s closing stock price on the date of grant. For the years ended December 31, 2022, 2021 and 2020, the weighted average fair value of RSU awards granted was $107.17 per share, $99.09 per share and $92.42 per share, respectively. As of December 31, 2022, 5.3 million RSUs were outstanding and unvested, with an aggregate intrinsic value of $445.1 million and a weighted average remaining vesting period of approximately 2.3 years. These RSUs are expected to vest on various dates through 2026.

Valuation allowances will be recognized on deferred tax assets if it is more-likely-than-not that some or all of the deferred tax assets will not be utilized. In measuring deferred tax assets, the Company considers all available evidence, both positive and negative, to determine whether a valuation allowance is needed. As of December 31, 2022, the Company recorded a $41.3 million valuation allowance against deferred tax assets related to state tax credits and state and foreign NOLs in which it is more-likely-than-not that such attributes will expire prior to utilization. The increase in the valuation allowance during 2022 was $4.1 million. The increase in the valuation allowance is primarily related to state tax credits.

The Company's NOL and tax credit carryforwards in U.S. federal, state and foreign jurisdictions as of December 31, 2022 and 2021 were as follows (in thousands, except years):

	2022		2021		Expirations at Various Dates Through:

The Company's U.S. federal and state NOL carryforwards relate to acquisitions completed in 2022, 2021, 2019, 2017 and 2012.

As of December 31, 2022, accumulated earnings outside the U.S. totaled $1.9 billion, the majority of which have been taxed due to the one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings and the tax on global intangible low taxed income required by the U.S. Tax Cuts and Jobs Act ("TCJA"). No provision for U.S. state income taxes and foreign withholding taxes has been provided for any remaining undistributed foreign earnings not subject to tax under the TCJA, or any additional basis differences inherent in the Company's international subsidiaries, as these amounts continue to be indefinitely reinvested. Determination of the amount of the unrecognized deferred tax liability on outside basis differences is not practicable because of the complexity of laws and regulations, the varying tax treatment of alternative repatriation scenarios and the variation due to multiple potential assumptions relating to the timing of any future repatriation.

The changes in the Company’s unrecognized tax benefits for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

As of December 31, 2022, 2021 and 2020, the Company had $38.3 million, $23.1 million and $29.5 million of unrecognized tax benefits, respectively. Total interest and penalties for unrecognized tax benefits includes $8.6 million, $7.2 million and $7.7 million as of December 31, 2022, 2021 and 2020, respectively. Interest and penalties related to unrecognized tax benefits are recorded in the provision for income taxes and were $2.0 million, $0.5 million and $1.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. The amount of unrecognized tax benefits that, if recognized, would impact the effective income tax rate is $38.3 million.

As of December 31, 2022, it is reasonably possible that $3.6 million of unrecognized tax benefits may be recognized within the next 12 months due to the expiration of local statutes of limitations. Certain U.S. state and foreign income tax returns from 2013 through 2022 are currently under audit. The Company has reserved for those positions that are not more-likely-than-not to be sustained.

Earnings Per Share [Abstract]

Net Income per Share

Net Income per Share

Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock options, RSUs, DSUs, convertible senior notes and warrants issued by the Company. For the year ended December 31, 2022, the dilutive effect of outstanding awards is reflected in diluted earnings per share by application of the treasury stock method and the dilutive effect of the convertible securities is reflected in diluted earnings per share by application of the if-converted method. For the years ended December 31, 2021 and 2020, the dilutive effect of outstanding awards and convertible securities is reflected in diluted earnings per share by application of the treasury stock method.

The components used in the computation of basic and diluted net income per share for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands, except per share data):

Diluted net income per share	$	3.26	$	3.93	$	3.37

For the years ended December 31, 2022, 2021 and 2020, certain potential outstanding shares from service-based RSUs, convertible notes and warrants were excluded from the computation of diluted net income per share because the effect of including these items was anti-dilutive. Additionally, certain performance-based RSUs were excluded from the computation of diluted net income per share because the underlying performance conditions for such RSUs had not been met as of these dates. The number of potentially outstanding shares excluded from the computation of diluted net income per share for the years ended December 31, 2022, 2021 and 2020 were as follows (in thousands):

	2022	2021	2020

Revision of Previously Issued Financial Statements

During the preparation of the financial statements for the year ended December 31, 2022, an error was identified in the Company’s accounting for an intercompany sale of intellectual property that occurred during 2022. During each of the first three quarters of 2022, the Company failed to record a deferred tax asset in the jurisdiction where the intellectual property was sold for the step up in tax basis that was achieved with the sale. This caused net deferred taxes to be understated in the interim condensed consolidated balance sheets, the provision for income taxes to be overstated and net income and earnings per share to be understated in the interim condensed consolidated statements of income. Management evaluated the error and determined that the related impact was not material to any of the Company's previously issued financial statements.

The financial data below has been derived from the Company’s quarterly reports on Form 10-Q filed for the respective periods, with 2022 periods adjusted to reflect the impact of the error. The Company will also correct previously reported financial information for this error in its future filings, as applicable.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2022

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ materially from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these financial statements include, but are not limited to, those related to revenue, accounts receivable and related reserves, valuation and impairment of investments and marketable securities, valuation and useful lives of acquired intangible assets, useful lives and realizability of long-lived assets, capitalized internal-use software development costs, income tax reserves and accounting for stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the date of the change in estimate.

Cash, Cash Equivalents and Marketable Securities

Cash, Cash Equivalents and Marketable Securities

Cash and cash equivalents consist of cash held in bank deposit accounts and short-term, highly-liquid investments with remaining maturities of three months or less at the date of purchase. Marketable securities consist of corporate, government and other securities. Securities having remaining maturities of less than one year from the date of the balance sheet are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets.

The Company classifies its fixed income securities with readily determinable market values as available-for-sale. These investments are classified as marketable securities on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature and reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of income. Gains and losses on investments are calculated on the basis of specific identification.

Marketable securities are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health and business outlook of the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends; and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Assessing the above factors involves inherent uncertainty. Write-downs, if recorded, could be materially different from the actual market performance of marketable securities in the Company’s portfolio if, among other things, relevant information related to the marketable securities was not publicly available or other factors not considered by the Company would have been relevant to the determination of impairment.

Accounts Receivable and Related Reserves

Accounts Receivable and Related Reserves

The Company’s accounts receivable balance includes unbilled amounts that represent revenue recorded for customers that are typically billed monthly in arrears. The Company records reserves against its accounts receivable balance which primarily consists of allowances for current expected credit losses. Increases and decreases in the allowance for current expected credit losses are included as a component of general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses has been developed using historical loss rates for the previous twelve months as well as expectations about the future where the Company has been able to develop forecasts to support its estimates. In addition, the allowance considers outstanding balances on a customer-specific, account-by-account basis. The Company assesses collectibility based upon a review of customer receivables from prior sales with collection issues where the Company no longer believes that the customer has the ability to pay for services previously provided. The Company also performs ongoing credit evaluations of its customers. If such an evaluation indicates that payment is no longer reasonably assured for services provided, any future services provided to that customer will result in the creation of a cash-basis reserve until the Company receives consistent payments. The Company does not have any off-balance sheet credit exposure related to its customers.

Revenue Recognition, Incremental Costs to Obtain a Contract with a Customer, Contract Liabilities and Cost of Revenue

Incremental Costs to Obtain a Contract with a Customer

The Company capitalizes incremental costs associated with obtaining customer contracts, specifically certain commission and incentive payments. The Company pays commissions and incentives up-front based on contract value upon signing a new arrangement with a customer and upon renewal and upgrades of existing contracts with customers if the renewal and upgrades result in an incremental increase in contract value. To the extent commissions and incentives are earned, the expenses, including estimated payroll taxes, are deferred on the Company's consolidated balance sheet and amortized over the expected life of the customer arrangement on a straight-line basis. Based on the nature of the Company's unique technology and services, and the rate at which the Company continually enhances and updates its technology, the expected life of the customer arrangement is determined to be approximately three years. Additionally, the Company may pay commissions and incentives based upon contract value, rather than incremental increase in contract value, to certain sales groups within the Company. For these commission arrangements, the Company amortizes capitalized costs for contract renewals over an average renewal contract period of 16 months. The Company also incurs commission expense on an ongoing basis based upon revenue recognized. In these cases, no incremental costs are deferred, as the commissions are earned and expensed in the same period for which the associated revenue is recognized.

Amortization of the costs is primarily included in sales and marketing expense in the consolidated statements of income. The current portion of deferred commission and incentive payments is included in prepaid expenses and other current assets, and the long-term portion is included in other assets on the Company's consolidated balance sheets.

Contract Liabilities

Contract liabilities primarily represent payments received from customers for which the related performance obligations have not yet been satisfied. These balances consist of the unearned portion of monthly service fees and integration fees and prepayments made by customers for future periods. The current and long-term portions of the Company's contract liabilities are included in deferred revenue in the respective sections of the Company's consolidated balance sheets.

Revenue Recognition

The Company primarily derives revenue from the sale of services to customers executing contracts having terms of one year or longer. Services included in the Company's contracts consist of its core services – the delivery of content, applications and software over the internet – as well as security and cloud computing solutions and professional services. Revenue is recognized upon transfer of control of promised services in an amount that reflects the consideration the Company expects to receive in exchange for those services.

The Company enters into contracts that may include various combinations of these services, which are generally capable of being distinct and accounted for as separate performance obligations. These contracts generally commit the customer to a minimum of monthly, quarterly or annual levels of usage and specify the rate at which the customer must pay for actual usage above the stated minimum. Based on the typical structure of the Company's contracts, which are generally for monthly

recurring services that are essentially the same over time and have the same pattern of transfer to the customer, most performance obligations represent a promise to deliver a series of distinct services over time.

The Company's contracts with customers sometimes include promises to deliver multiple services to a customer. Determining whether services are distinct performance obligations often requires the exercise of judgment by management. For example, advanced features that enhance a service and are highly interrelated are generally not considered distinct; rather, they are combined with the service they relate to into one performance obligation. Different determinations related to combining services into performance obligations could result in differences in the timing and amount of revenue recognized in a period.

Generally, the transaction price in a contract is equal to the committed price stated in the contract, less any discounts or rebates. The Company's typical contracts qualify for series accounting, and the pricing terms generally do not require estimation of the transaction price beyond the reporting period. As a result, any incremental fees generated as a result of usage or “bursting” over committed contract levels are recorded in the period to which the services relate. The amount of consideration recognized for usage above contract minimums is limited to the amount the Company expects to be entitled to receive in exchange for providing the services. Once the transaction price has been determined, the Company allocates such price among all performance obligations in the contract on a relative standalone selling price (“SSP”) basis.

Determination of SSP requires the exercise of judgment by management. SSP is based on observable inputs such as the price the Company charges for the service when sold separately or the discounted list price per management’s approved price list. In cases where services are not sold separately or price list rates are not available, a cost-plus-margin approach or adjusted market approach is used to determine SSP.

Most content delivery and security services represent stand-ready obligations that are satisfied over time as the customer simultaneously receives and consumes the benefits provided by the Company. Accordingly, revenue for those services is recognized over time, generally ratably over the term of the arrangement due to consistent monthly usage commitments that expire each period. Any bursting over given commitments is recognized in the period in which the traffic was served. For services that involve traffic consumption, revenue is recognized in an amount that reflects the level of traffic served to a customer in a given period. For custom arrangements, other methods may be used as a measure of progress towards satisfying the performance obligations.

Some of the Company's contracts are satisfied at a point in time, such as one-time professional services, integration services and most license sales where the primary obligation is delivery of the license at the start of the term. In these cases, revenue is recognized at the point in time of delivery or satisfaction of the performance obligation.

From time to time, the Company enters into contracts to sell its services or license its technology to unrelated enterprises at or about the same time that it enters into contracts to purchase products or services from the same enterprises. Consideration payable to a customer is reviewed as part of the transaction price. If the payment to the customer does not represent payment for a distinct service, revenue is recognized only up to the net amount of consideration after customer payment obligations are considered. The Company may also resell the licenses or services of third parties. If the Company is acting as an agent in an arrangement with a customer to provide third party services, the transaction price reflects only the net amount to which the Company will be entitled, after accounting for payments made to the third party responsible for satisfying the performance obligation.

Cost of Revenue

Cost of revenue consists primarily of fees paid to network providers for bandwidth and to third-party network data centers for housing servers, also known as co-location costs. Cost of revenue also includes employee costs for services delivery and network operation, build-out and support of the Company's network; network storage costs; cost of software licenses; depreciation of network equipment used to deliver the Company’s services; amortization of network-related internal-use software; and costs for the production of live events streamed by the Company for customers. The Company enters into contracts for bandwidth with third-party network providers with terms typically ranging from several months to five years. These contracts generally commit the Company to pay minimum monthly fees plus additional fees for bandwidth usage above the committed level. In some circumstances, internet service providers (“ISPs”) make rack space available for the Company to locate its servers and provide access to their bandwidth at a discount or no cost. Although the Company does not provide any goods or services to the ISPs or the ISPs’ customers under these arrangements, the ISPs and their customers indirectly benefit by accessing content through a local Company server, resulting in better content delivery. The Company records the cost of these vendor relationships at their negotiated transaction price, which is either at a discount or no cost.

Concentrations of Credit Risk

Concentrations of Credit Risk

The amounts reflected in the consolidated balance sheets for accounts receivable, other current assets, accounts payable, accrued liabilities and other current liabilities approximate fair values due to their short-term maturities. The Company maintains the majority of its cash, cash equivalents and marketable securities with major financial institutions that the Company believes to be of high credit standing. The Company believes that, as of December 31, 2022, its concentration of credit risk related to cash equivalents and marketable securities was not significant.

Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which the Company makes substantial sales. The Company’s customer base consists of a large number of geographically-dispersed customers diversified across several industries. To reduce risk, the Company routinely assesses the financial strength of its customers. Based on such assessments, the Company believes that its accounts receivable credit risk exposure is limited. For the years ended December 31, 2022, 2021 and 2020, no customer accounted for more than 10% of total revenue. As of December 31, 2022 and 2021, there was one customer with an accounts receivable balance greater than 10% of total accounts receivable. The Company believes that, as of December 31, 2022 and 2021, its concentration of credit risk related to accounts receivable was not significant.

Fair Value of Financial Measurements

Fair Value of Financial Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company has certain financial assets and liabilities recorded at fair value, principally cash equivalents and short- and long-term marketable securities that have been classified as Level 1, 2 or 3 within the fair value hierarchy. Fair

values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the reporting date. Fair values determined by Level 2 inputs utilize data points other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair values determined by Level 3 inputs are based on unobservable data points for the asset or liability.

Property and Equipment

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Property and equipment generally include purchases of items with a per-unit value greater than $1,000 and an estimated useful life greater than one year. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the related lease terms or their estimated useful lives.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in income from operations. Repairs and maintenance costs are expensed as incurred.

Operating Leases

Operating Leases

The Company enters into operating leases for real estate assets related to office space and co-location assets related to space or racks at co-location facilities and related equipment for its servers and other networking equipment. The Company determines if an arrangement contains a lease at the inception of a contract by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration and the right to obtain the economic benefits from the use of the identified asset.

Upon commencement of a lease, the Company records a right-of-use asset that represents the Company’s right to use the underlying asset for the lease term and a lease liability that represents an obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Lease payments are discounted at the lease commencement date. As the Company’s leases do not provide an implicit rate, an incremental borrowing rate has been applied based on the Company's credit-adjusted risk-free rate.

The Company often enters into contracts that contain both lease and non-lease components. Real estate non-lease components include real estate taxes, insurance, maintenance, parking and other operating costs. Co-location non-lease components include utilities and other operating costs. The Company includes both lease and non-lease components of fixed costs in its lease arrangements as a single lease component. Variable costs, such as utilities based on actual usage, are not included in the measurement of right-of-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs.

The Company’s lease terms often include renewal options and, particularly in the case of co-location arrangements, may include evergreen provisions. The Company’s right-of-use assets and lease liabilities generally do not include the options to extend, or terminate, unless it is reasonably certain that the Company will exercise these options. The Company has elected to exclude leases for certain networking equipment and leases assumed through acquisitions with terms of 12 months or less from its right-of-use assets and lease liabilities on its consolidated balance sheets.

Lease expense is recognized on a straight-line basis over the expected lease term.

Equity Method Investments

Equity Method Investments

The Company accounts for equity investments in which it has significant influence, but not a controlling financial interest, using the equity method of accounting. Under the equity method of accounting, investments are initially recorded at cost, less impairment, and subsequently adjusted to recognize the Company’s share of earnings or losses.

Goodwill, Acquired Intangible Assets and Long-Lived Assets

Goodwill, Acquired Intangible Assets and Long-Lived Assets

Goodwill is the amount by which the cost of acquired net assets in a business combination exceeds the fair value of the net identifiable assets on the date of purchase and is carried at its historical cost. The Company tests goodwill for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company performs its impairment test of goodwill as of December 31 each year. As of December 31, 2022, 2021 and 2020, the Company concluded that it has one reporting unit and that its chief operating decision maker is its chief executive officer and the executive management team. The Company has assigned the entire balance of goodwill to one reporting unit. The fair value of the reporting unit was based on the Company's market capitalization as of each of December 31, 2022 and 2021, and it was substantially in excess of the carrying value of the reporting unit at each date. The fair value of the Company's reporting unit was determined by the Company's enterprise value as of the years ended December 31, 2022, 2021 and 2020.

Acquired intangible assets consist of completed technologies, customer relationships, trademarks and trade names, non-compete agreements and acquired license rights. Acquired intangible assets, other than goodwill, are amortized over their estimated useful lives based upon the estimated economic value derived from the related intangible asset. Significant judgment is used in determining fair values of acquired intangibles assets and their estimated useful lives. Fair value and useful life determinations may be based on, among other factors, estimates of future expected cash flows, royalty cost savings and appropriate discount rates used in calculating present values.

Long-lived assets, including property and equipment, operating lease right-of-use assets and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances, such as service discontinuance, technological obsolescence, significant decreases in the Company’s market capitalization, facility closures or work-force reductions indicate that the carrying amount of the long-lived asset may not be recoverable. When such events occur, the Company compares the carrying amount of the asset to the undiscounted expected future cash flows related to the asset. If this comparison indicates that an impairment is present, the amount of the impairment is calculated as the difference between the carrying amount and the fair value of the asset.

Research and Development Costs and Capitalized Internal-Use Software

Research and Development Costs and Capitalized Internal-Use Software

Research and development costs consist primarily of payroll and related personnel costs for the design, development, deployment, testing and enhancement of the Company’s services and network. Costs incurred in the development of the Company’s services are expensed as incurred, except certain internal-use software development costs eligible for capitalization.

Capitalized costs include external consulting fees, payroll and payroll-related costs and stock-based compensation for employees in the Company’s development and information technology groups who are directly associated with, and who devote time to, the Company’s internal-use software projects. Capitalization begins when the planning stage is complete and the Company commits resources to the software project; capitalization continues during the application development stage. Capitalization ceases when the software has been tested and is ready for its intended use. Costs incurred during the planning, training and post-implementation stages of the software development life-cycle are expensed as incurred. The Company amortizes completed internal-use software that is used on its network to cost of revenue over its estimated useful life.

Accounting for Stock-Based Compensation

Accounting for Stock-Based Compensation

The Company recognizes compensation costs for all stock-based payment awards made to employees based upon the awards’ grant-date fair value. The stock-based payment awards include stock options, restricted stock, restricted stock units, deferred stock units and employee stock purchases related to the Company’s employee stock purchase plan.

For stock options, the Company has selected the Black-Scholes option-pricing model to determine the fair value of stock option awards. For stock awards with market-based vesting conditions, the Company uses a Monte Carlo simulation to determine the fair value of the award. For stock options, restricted stock units and deferred stock units that contain only a service-based vesting feature, the Company recognizes compensation cost on a straight-line basis over the award's vesting period. For awards with a performance condition-based vesting feature, the Company recognizes compensation cost on a graded-vesting basis over the award's expected vesting period, commencing when achievement of the performance condition is deemed probable. In addition, for awards that vest and become exercisable only upon achievement of specified performance conditions, the Company makes judgments and estimates each quarter about the probability that such performance conditions will be met or achieved. Any changes to those estimates that the Company makes from time to time may have a significant impact on the stock-based compensation expense recorded and could materially impact the Company’s results of operations.

Foreign Currency Translation and Forward Currency Contracts

Foreign Currency Translation and Forward Currency Contracts

The assets and liabilities of the Company's subsidiaries are translated at the applicable exchange rate as of the balance sheet date, and revenue and expenses are translated at an average rate over the period. Resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss, a separate component of stockholders’ equity. Gains and losses on inter-company and other non-functional currency transactions are recorded in other income (expense), net.

The Company enters into short-term foreign currency forward contracts to offset foreign exchange gains and losses generated by the re-measurement of certain assets and liabilities recorded in non-functional currencies. Changes in the fair value of these derivatives, as well as re-measurement gains and losses, are recognized in current earnings in other income (expense), net. As of December 31, 2022 and 2021, the fair value of the forward currency contracts and the underlying gains and losses for the years ended December 31, 2022, 2021 and 2020 were immaterial.

The Company's foreign currency forward contracts may be exposed to credit risk to the extent that its counterparties are unable to meet the terms of the agreements. The Company seeks to minimize counterparty credit (or repayment) risk by entering into transactions only with major financial institutions of investment grade credit rating.

Income Taxes

Income Taxes

The Company's provision for income taxes is comprised of a current and a deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current year. The deferred income tax provision is calculated as the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse or the carryforwards are expected to be realized.

    The Company currently has net deferred tax assets consisting of net operating loss (“NOL”) carryforwards, tax credit carryforwards and deductible temporary differences. Management periodically weighs the positive and negative evidence to determine if it is more-likely-than-not that some or all of the deferred tax assets will be realized.

    The Company has recorded certain tax reserves to address potential exposures involving its income tax positions. These potential tax liabilities result from the varying application of statutes, rules, regulations and interpretations by different taxing jurisdictions. The Company's estimate of the value of its tax reserves contains assumptions based on past experiences and judgments about the interpretation of statutes, rules and regulations by taxing jurisdictions. It is possible that the costs of the ultimate tax liability or benefit from these matters may be more or less than the amount the Company estimated.

    Uncertainty in income taxes is recognized in the Company's consolidated financial statements using a two-step process. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination. If the tax position is deemed more-likely-than-not to be sustained based on technical merit, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement.

Newly-Adopted Accounting Pronouncements and Recent Accounting Pronouncements

Newly-Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board ("FASB") issued guidance that was expected to reduce complexity and improve comparability of financial reporting associated with accounting for convertible instruments and contracts in an entity’s own equity. The Company adopted this guidance on January 1, 2022 on a modified retrospective basis.

The convertible senior notes included on the Company's consolidated balance sheet more closely reflect the principal amounts. Prior to the adoption of this guidance, the Company separated its convertible senior notes into a liability and an equity component. The equity portion is now eliminated. The cumulative effect of the changes was an increase to convertible senior notes of $304.7 million, an increase to deferred income tax liabilities of $0.7 million, an increase to deferred income tax assets of $77.7 million, a decrease to property and equipment of $7.7 million and a decrease to additional paid-in capital of $375.4 million on the consolidated balance sheet. The net effect of these adjustments was recorded as an increase to retained earnings as of January 1, 2022.

Additionally, the new guidance eliminates the use of the treasury stock method for convertible instruments that can be settled in whole or in part with equity, when calculating diluted earnings per share. Instead, it requires application of the if-converted method. Under that method, diluted earnings per share would generally be calculated assuming that all the convertible senior notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. The application of the if-converted method reduces the Company’s reported diluted earnings per share after the adoption date. However, in December 2021, the Company made an irrevocable election to settle the principal portion of the convertible senior notes with cash. Accordingly, the if-converted method is only impacted by any potential shares to be delivered for the amount in excess of the principal portion. The changes to the diluted earnings per share guidance did not materially impact the Company's results of operations.

With the elimination of the debt discount created by the equity component, amortization of the debt discount is eliminated, which decreases interest expense, and therefore increases net income and earnings per share, from the period of adoption. This had the effect of increasing basic and diluted earnings per share for the year ended 2022 by $0.32.
