We enable businesses of Contentsall sizes to revolutionize how they engage with their customers by delivering seamless, trusted and personalized customer experiences at scale. Our leading customer engagement platform comprises communications application programming interfaces (“APIs”) that enable developers to embed numerous forms of messaging, voice, and email interactions into their customer-facing applications, as well as software products that target specific engagement needs, including our customer data platform, digital engagement centers, marketing campaigns and advanced account security solutions. This combination of flexible APIs and software solutions helps businesses of all sizes and across numerous industries to benefit from smarter and more streamlined engagement at every step of the customer journey, including reduced customer acquisition costs, lasting loyalty and increased customer value. Our platform, which combines our highly customizable communications APIs with customer data management capabilities, allows businesses to break down data silos and build a comprehensive single source for their customer data that is organized into unique profiles that are easily accessible by all their business teams. Empowered with this information and the insights it enables, businesses using our platform can provide robust, personalized and effective communications to their customers at every stage of their customer relationships. The value proposition of our offerings has become stronger and our products have become more strategic to our customers as more and more businesses have prioritized building more personalized and more differentiated customer engagement experiences through digital channels.

In February 2023, we began operating our business in two business units: Twilio Communications (“Communications”) and Twilio Data & Applications (“Data & Applications”), which has since been renamed Twilio Segment. Our Communications business consists of a variety of APIs and software solutions to optimize communications between our customers and their end users. Our key Communications offerings include Messaging, Voice, Email, Flex, Marketing Campaigns, and User Identity and Authentication. Our Segment business consists of software products that enable businesses to leverage their first-party data to create unique customer profiles and achieve more effective customer engagement. Our key Segment offerings are Segment and Engage. Together, our Communications and Segment products power our customer engagement platform. We believe that our two business units are complementary and address adjacent needs and related problems for our customers. Our goal is to create a flywheel for effective customer engagement by combining Segment’s user profiles with our rich Communications data to drive more personalized and intelligent customer interactions. We believe that our business unit structure enables each business unit to execute toward its respective goals with appropriate focus and independence, best positioning us to achieve our long-term plan of creating the leading customer engagement platform.

In 2023, we revealed CustomerAI, which refers to generative and predictive artificial intelligence (“AI”) and machine learning (“ML”) capabilities and initiatives that we believe have the potential to increase the power and reach of our platform, make every interaction more personalized and intelligent, and accelerate our data and communications flywheel described above, benefiting both our Communications and Segment products.

We have experienced substantial growth in our business since inception, and as of December 31, 2023, we had over 305,000 Active Customer Accounts representing organizations from small and medium-sized business to large enterprises across a broad range of industries. Our growth has predominantly been organic as a result of new customer acquisition, as well as customers increasing their usage of our products, extending their usage of our products to new applications, or adopting new products that we offer. We have also fueled our growth through strategic acquisitions and integrations of businesses that complemented our pre-existing products and allowed us to expand our platform and to add new customer accounts.

We generate revenue from our platform through a combination of usage-based and subscription-based fees, which varies by product as indicated below and described in further detail in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Communications
Our Communications solutions consist of highly customizable APIs and products that can be used individually or in combination to build rich contextual communications within applications, allowing developers to build omnichannel engagements with customers worldwide. Communications also includes our omnichannel digital engagement center, as well as solutions for user identity and authentication and advanced compliance management to support success within a changing ecosystem of regulations. In the fourth quarter of 2023, we moved Flex and Marketing Campaigns from our Data & Applications (since renamed Segment) business unit to our Communications business unit.

Our Strategy
Our goal is to develop great APIs that developers love. These developers are our champions and bring us “in” to companies of every type, most frequently utilizing our messaging and email tools as an entry point. This “in” motion creates initial relationships with customers of all sizes including major enterprises that allow us to move “up”deliver the software stack and provide those companies with software solutions that address theirleading customer engagement requirements from marketingplatform. We are concentrating on the highest-impact product areas for our future, and we intend to salespursue the following strategies:
Optimizing and support. Today,Growing Communications. In our Communications solutions, we offer Twilio Campaigns for marketing, Twilio Flex for customer support and Twilio Verify to onboard and recognize customers. The more strategic nature of these software products also allows us to move up the organization chart, interacting with more senior and strategic purchasers. This “in” and “up” strategy is a motion we workare focusing on improving every day.profitability and growing our market share. To achieve this, we are focused on bolstering our independent software vendor (“ISV”) relationships, improving our self-service capabilities, cross-selling our Communications products, driving product innovation and expanding internationally, while further optimizing our business through simplification of business processes and modernization of our infrastructure.
Winning in Customer Data with Segment. To support growing our market share, we are focused on Segment’s interoperability across the data ecosystem. We will also continue to invest aggressivelyin predictive and generative AI to help customers increase the value and impact of Segment in customer engagement. In addition, we are conducting an operational review of our Segment business expected to be completed in March 2024, which will inform our strategy with respect to Segment going forward.
Driving Operating Leverage Across our Business. We are implementing several organizational initiatives targeted at improving efficiencies of our processes, enhancing our fiscal discipline on all levels, optimizing utilization of our distributed workforce, driving agile decision-making frameworks and more. We expect that these initiatives will result in operating cost reductions and increase effectiveness and efficiency within our organization.
Leveraging AI. We are continuing to invest in AI and ML capabilities, including both our CustomerAI capabilities and also internal applications of AI and ML to automate processes and help our business run more efficiently. We believe AI and ML have the potential to increase the power and reach of our platform, make every interaction more personalized and intelligent, and accelerate our data and communications flywheel, benefiting both our Communications and Segment products.
Competition

The markets for our products are rapidly evolving and are increasingly competitive. In our Communications business, our competitors are primarily (i) communications platform-as-a-service (“CPaaS”) companies that offer communications products and applications, (ii) other software companies that compete with portions of our communications product line, and (iii) regional network service providers that offer limited developer functionality on top of their own physical infrastructure. In our Segment business, our competitors are primarily (i) software-as-a-service (“SaaS”) companies and marketing cloud platform vendors that offer bundled applications and platforms, (ii) customer relationship management (“CRM”) and customer experience vendors and (iii) standalone customer data platform vendors.

The principal competitive factors in these markets include completeness of offering, credibility with customers, global reach, ease of integration and programmability, product features, platform scalability, reliability, deliverability, security and performance, brand awareness and reputation, the strength of sales and marketing efforts, customer support, and the cost of deploying and using products.
We believe that we compete favorably on the basis of the factors listed above and that none of our competitors currently compete directly with us across all of our product offerings. With the introduction of new products and services and new market entrants, we expect competition to intensify in the future.
Research and Development
Our research and development efforts are focused on building a trusted, comprehensive customer engagement platform while enhancing our existing products and developing new products and features.

Our research and development organization is predominantly built around small development teams. Our small development teams foster greater agility, which enables us to develop new, innovative products and make rapid changes to our infrastructure that increase resiliency and operational efficiency. Our development teams designed and built much of our customer engagement platform, our core platforms stack, as well as our Super Network. These teams continue to focus on the highest impact product areas for our future, which includes focusing on continued innovation in the face of rapid technological change and changing industry practices. We are continuing to invest in AI and ML capabilities, which we believe have the potential to enhance both our Communications and Segment offerings, as well as to automate processes and help our business run more efficiently.
As of December 31, 2023, we had 2,563 employees in our research and development organization.
Sales and Marketing
Our sales and marketing teams work closely together to drive awareness and adoption of our platform. We leverage our brand, developer network and conferences, such as SIGNAL, to expand our developer and self-service sales motions. We further complement this with sales development, inside sales, field marketing, and sales and solutions engineering to support enterprise, ISV, partner, and mid-market sales motions.
Our go-to-market model for our Communications business has three pillars: self-service developers, ISV partners, and enterprise customers. Developers are able to access our easy-to-configure APIs, extensive self-service documentation and customer support team, to embed our communications products into their applications during an initial free trial period. Customers can then provide their credit card information to make an upfront prepayment that is drawn down as they use our products. ISVs leverage our Communications APIs to build software and services that they can resell to customers across a varying number of use cases and verticals. Enterprise customers have access to our solutions team to support their businesses across their customer journey.
Our go-to-market model for our Segment business requires a consultative solution-oriented sales model that emphasizes value-based discovery, technical proof of concept, and customer relationship building. We are deliberate in developing these skills and customer relationships leveraging the trust and reputation we have built while solving new and broader problems for our customers. Our sales organization targets technical, marketing and business leaders who are seeking to leverage software to drive superior customer engagement and competitive differentiation.
Additionally, when potential customers do not have the available developer resources to build their own applications, we refer them to our technology partners who embed our products in the solutions that they sell to other businesses (such as contact centers and marketing automation), our professional services team or outside consulting partners who provide consulting and development services for organizations that have limited resources or expertise to build our platform approach,into their software applications or technology stacks.
As of December 31, 2023, we had 2,631 employees in our sales and marketing organization.
Customer Support
To make it easy to learn how to use our products, we provide all of our users with comprehensive documentation, how-to guides and tutorials. We supplement and enhance these tools with the participation of our engaged customer community. In addition, we provide support options to address the individualized needs of our customers. All of our customers get free support and system status notifications. Our customers can also engage with the broader Twilio community to resolve issues.
For our Communications products, we generally offer three paid tiers of support with increasing levels of availability and guaranteed response times. Our highest tier plan, intended for our largest customers, includes a designated support engineer, duty manager coverage and quarterly status reviews. Similarly, our subscription products generally feature a base level of customer support plus premium, paid support options. Our support model is global, with coverage available 24x7. We currently derive an insignificant amount of revenue from fees for customer support.
We also offer professional services which prioritizes increasingprovide in-depth, hands-on, fee-based packages of advisory, software architecture, integration and coding services to existing and prospective customers and partners to optimize their use of the Twilio platform. For Flex and Segment, offerings include services for implementing digital engagement center solutions and customer data platform design. For our reachother Communications products, offerings include email implementation and scale.

“pay-for-performance”
philosophy, our executive compensation program heavily emphasizes “variable” pay over “fixed” pay.
In 2021, the majority5,867 employees, including 2,337 employees located outside of the target total direct compensationU.S. Although we have works council, statutory and/or collective bargaining employee representation obligations in certain countries outside of the U.S., none of our Chief Executive Officer consisted of variable payU.S. employees are represented by a labor union with respect to their employment.

We consider our relations with our employees to be good and have not experienced interruptions of operations or work stoppages due to labor disagreements.
We are committed to embedding and operationalizing diversity, equity, and inclusion (“DEI”) across our business. More information on our approach to DEI and how we work to build a diverse and inclusive workplace can be found in our annual Impact and DEI reports, available on our website.

Our executive compensation program is designed so that a significant portion of our executive officers’ target total direct compensation is equity-based, and therefore “at risk,” to align the interests of our executive officers and stockholders.
No Short-Term Cash Bonus Program or Guaranteed Bonuses.
We do not maintain a formal cash bonus program for our executive officers, nor do we provide guaranteed bonuses to our executive officers. As described below, Mr. Boroditsky participates in our sales commission program.
“Double-Trigger”
Change-in-Control
Arrangements.
Post-employment compensation arrangements for all current executive officers in the event of a change in control of the Company are “double-trigger” arrangements that require both a change in control of the Company plus a qualifying termination of employment before payments and benefits are paid. All such payments and benefits are also subject to the execution and delivery of an effective release of claims in our favor.
Limited Perquisites or Other Personal Benefits.
We provide limited perquisites and other personal benefits to our executive officers, which, in 2021, consisted of matching contributions to Section 401(k) accounts and reimbursements for our Chief Executive Officer’s costs incurred in connection with his filing under the Hart-Scott-Rodino Antitrust Improvement Act of 1976 (“
HSR
”) and related tax gross up and legal fees.
Maintain an Independent Compensation and Talent Management Committee.
Our compensation and talent management committee consists solely of independent,
non-employee
directors.
Limited Tax Payments on Perquisites.
Except as otherwise specified, we generally do not provide any tax reimbursement payments (including
“gross-ups”)
on any perquisites or other personal benefits.
Retain an Independent Compensation Advisor.
Our compensation and talent management committee has engaged its own independent compensation advisor to provide information, analysis and other advice on executive compensation independent of management.
No Excise Tax Payments on Future Post-Employment Compensation Arrangements.
We do not provide any excise tax reimbursement payments (including
“gross-ups”)
with respect to payments or benefits contingent upon a change in control of our Company.
Annual Executive Compensation Review.
Our compensation and talent management committee conducts an annual review of our compensation strategy, including a review of our compensation peer group used for comparative and benchmarking purposes.
No Hedging.
We prohibit our employees, including our executive officers, and the
non-employee
members of our board of directors from engaging in hedging transactions or certain derivative transactions relating to our securities.
Annual Compensation-Related Risk Assessment.
Our compensation and talent management committee reviews, on an annual basis, our compensation-related risk profile.
No Pledging.
We prohibit our executive officers and the
non-employee
members of our board of directors from holding our securities in a margin account or pledging our securities as collateral for a loan.
Stock Ownership Policy.
We maintain a robust stock ownership policy for our Chief Executive Officer, our other named executive officers and the
non-employee
members of our board of directors.
No Special Welfare or Health Benefits.
We do not provide our executive officers with any special welfare or health benefit programs, and participation in the employee programs that are standard in our industry sector is on the same basis as all of our full-time employees.

Commitment to Stockholder Engagement
As we manage our business with a focus on continued innovation and growth, we recognize that our compensation program must balance stockholder perspectives with our ability to retain and attract the highest caliberis fair for all employees, regardless of talent to help facilitate growth at scale. Our board of directors and our compensation and talent management committee value the stockholder perspectives we receive, through direct engagement as well as through voting decisions, including our annual
Say-on-Pay
Vote at our annual stockholder meetings, and the compensation-related feedback we receive from stockholders is an important component that informs the compensation and talent management committee’s decision-making process when reviewing our executive compensation programs each year.
We have established a robust stockholder engagement program to help us better understand the perspectives of our stockholders. In 2021, in addition to our standard engagement with stockholders throughout the year, we conducted meetings with several of our large stockholders, with participation from our management team and certain members of our board of directors, including Mses. Donio and Rottenberg, the chairpersons of our compensation and talent management committee and nominating and corporate governance committee, respectively, on topics ranging from compensation strategy, to board structure and corporate governance, to environmental, social and governance matters (“
ESG
”). In addition, our head of investor relations regularly communicates stockholder feedback to senior management and the board of directors for consideration in their decision-making.
The 2021 executive compensation program was implemented in early 2021, and the compensation and talent management committee, in connection with input from our full board of directors, determined at that time that our concentration on equity compensation, particularly the grant of equity awards in the form of 50% (by fair value) stock options and 50% (by fair value) RSUs with time-based vesting, is aligned with long-term stockholder value. However, our compensation and talent management committee continues to assess the Company’s equity compensation practices in light of the Company’s continued growth and maturation as well as discussions with stockholders and determined to implement changes to our executive compensation program beginning in 2022 to grant performance-based equity awards as part of our executive compensation program, as discussed in “Evolving our Executive Compensation Program” below.
We believe the addition of performance-based equity awards, as well as other enhancements to our governance practices and disclosures in response to stockholder feedback,classifications, such as increasing our stock ownership requirements for directorsrace and executive offices and enhancing our ESG disclosures, have advanced our compensation practices and governance ingender. We routinely run a manner that both benefits stockholders and continuesrigorous statistical analysis to align with our strategy and pay philosophy.
Executive Compensation Philosophy
We operate in an extremely competitive market where there is substantial and continuous competition for leadership with the experience and skill to lead in a dynamic and innovative industry. Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance and aligning the compensation of our executive officers with the long-term interests of our stockholders. Consistent with this philosophy, we designed our executive compensation program to achieve the following primary objectives:
attract, motivate, incentivize and retain employees at the executive level who contribute to our long-term success;
provide compensation packages to our executive officers that are competitive and reward the achievement of our business objectives; and
effectively align our executive officers’ interests with the interests of our stockholders by focusing on long-term equity incentives that correlate with the growth of sustainable long-term value for our stockholders.
12

Table of Contents
Because we do not have a cash bonus program for our executive officers, generally, our compensation and talent management committee has sought to set base salaries at the higher end of the competitive market range to provide what it believes to be reasonable cash compensation levels and will serve to attract and retain our executive officers. Further, our compensation and talent management committee tends to weight the target total direct compensation opportunities of our executive officers more heavily towards equity compensation. We understand the importance of linking the individual performance of our executive officers and the financial and operational performance of our company to our overall executive compensation program. We believe our strong focus on, and heavy weighting toward, equity compensation supports that philosophy and has worked to align our executive compensation with the interests of our stockholders. However, we continue to review the current equity compensation trends as well as the feedback from our stockholders in regard to our executive compensation program.
Evolving our Executive Compensation Program
In March 2022, in addition to granting time-based restricted stock unit awards to our named executive officers, our compensation and talent management committee also granted performance-based restricted stock unit awards. The performance-based awards vest based on the achievement of certain goals over specified performance periods, including year-over year organic revenue growth rates and
non-GAAP
operating profit, and are intended to further align the interests of our named executive officers and our stockholders.
Oversight of Executive Compensation Program
Role of the Compensation and Talent Management Committee
Our compensation and talent management committee discharges many of the responsibilities of our board of directors relating to the compensation of our executive officers, including our named executive officers, and the
non-employee
members of our board of directors (as described further below under the heading
“Non-Employee
Director Compensation”). Our compensation and talent management committee has overall responsibility for overseeing our compensation structure, policies and programs generally, and overseeing and evaluating the compensation plans, policies and practices applicable to our executive officers. Our compensation and talent management committee also oversees the annual evaluation of our executive officers, including our named executive officers, for the prior fiscal year and has the authority to retain, and has retained, an independent compensation consultant to provide support to the committee in its review and assessment of our compensation programs.
Compensation-Setting Process
Our compensation and talent management committee determines the target total direct compensation opportunities for our executive officers, including our named executive officers. Our compensation and talent management committee does not use a single method or measure in developing its recommendations, nor does it establish one specific target for the total direct compensation opportunities of our executive officers. Rather, it retains flexibility to pay our executive officers within certain ranges. Nonetheless, our compensation and talent management committee generally begins its deliberations on cash and equity compensation levels with reference to various percentile levels for cash compensation and target total direct compensation as reflected in competitive market data, with an intended result of weighting compensation more heavily towards equity compensation.
When formulating its recommendations for the amount of each compensation element and approving each compensation element and the target total direct compensation opportunity for our executive officers, our compensation and talent management committee considers the following factors:
our performance against the financial and operational objectives established by our compensation and talent management committee and our board of directors;
13

Table of Contents
our financial performance relative to our compensation peer group;
the compensation levels and practices of our compensation peer group;
each individual executive officer’s skills, experience and qualifications relative to other similarly situated executives at the companies in our compensation peer group and in selected broad-based compensation surveys;
our desire to retain experienced and talented executives in a highly competitive market;
the scope of each individual executive officer’s role compared to other similarly situated executives at the companies in our compensation peer group and in selected broad-based compensation surveys;
the performance of each individual executive officer, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or function and ability to work as part of a team, all of which reflect our core values;
compensation parity among our individual executive officers; and
the recommendations provided by our Chief Executive Officer with respect to the compensation of our other executive officers.
These factors provide the framework for compensation decision-making and final decisions regarding the compensation opportunity for each executive officer. No single factor is determinative in setting pay levels, nor was the impact of any factor on the determination of pay levels quantifiable. Our compensation and talent management committee reviews the base salary levels and long-term incentive compensation opportunities of our executive officers, including our named executive officers, each fiscal year at the beginning of the year, or more frequently as warranted. Long-term incentiveensure compensation is granted on a regularly-scheduled basis, as described in “Other Compensation Policies and Practices—Equity Awards Grant Policy” below.
Role of Chief Executive Officer
In discharging its responsibilities, our compensation and talent management committee consults with members of our management, including our Chief Executive Officer. Our management assists our compensation and talent management committee by providing information on corporate and individual performance, market compensation data and management’s perspective on compensation matters. Our compensation and talent management committee solicits and reviews our Chief Executive Officer’s recommendations and proposals with respect to adjustments to annual cash compensation, long-term incentive compensation opportunities, program structures and other compensation-related matters for our executive officers, other than with respect to his own compensation.
Our compensation and talent management committee reviews and discusses these recommendations and proposals with our Chief Executive Officer and considers them as one factor in determining the compensation for our executive officers, including our other named executive officers. Our Chief Executive Officer recuses himself from all deliberations and determinations regarding his own compensation.
Role of Compensation Consultant
Our compensation and talent management committee engages an external independent compensation consultant to assist it by providing information, analysis and other advice relating to our executive compensation program and the decisions resulting from its annual executive compensation review. For 2021, our compensation and talent management committee engaged Compensia as its compensation consultant to advise on executive compensation matters, including competitive market pay practices for
14

Table of Contents
our executive officers, the selection of our compensation peer group, and data analysis. For 2021, the scope of Compensia’s engagement included:
researching, developing and reviewing our compensation peer group;
reviewing and analyzing the compensation for our executive officers, including our named executive officers;
supporting the design and implementation of changes to our executive long-term incentive strategy;
reviewing and providing input on the Compensation Discussion and Analysis section of this Amendment;
reviewing and analyzing the compensation of the
non-employee
members of our board of directors;
reviewing short-term incentive compensation practices and considerations;
reviewing peer group executive incentive compensation practices;
reviewing peer group executive severance and change in control practices;
reviewing our executive compensation philosophy;
conducting a compensation risk assessment;
advising regarding
non-employee
director compensation; and
supporting other ad hoc matters throughout the year.
The terms of Compensia’s engagement included reporting directly to our compensation and talent management committee and to our compensation and talent management committee chairperson. Compensia also coordinated with our management for data collection and job matching for our executive officers and provided data and analyses in connection with the review of our equity strategy. In 2021, Compensia did not provide any other services to us. In March 2021, our compensation and talent management committee evaluated Compensia’s independence pursuant to NYSE and LTSE Listing Standards and the relevant SEC rules and determined that no conflict of interest had arisen as a result of the work performed by Compensia.
Use of Market Data
For purposes of comparing our executive compensation against the competitive market, our compensation and talent management committee reviews and considers the compensation levels and practices of a group of peer companies. This compensation peer group consists of technology companies that are similar to us in terms of industry, revenue and market capitalization.
Our compensation and talent management committee reviews our compensation peer group at least annually and makes adjustments to its composition if warranted,fair, taking into account changes in both our businessfactors that should impact pay, like role, level, location, and the businesses of the companies in the peer group, and input from its compensation consultant. Accordingly, the peer group that was used for comparative purposes for 2021 was approved in September 2020.
In developing the compensation peer group for 2021, the following criteria were evaluated in identifying comparable companies:
similar industry and competitive market for talent;
within a range of 0.5x to 2.0x of our projected revenue for the following four fiscal quarters (as of August 2020); and
within a range of 0.25x to 4.0x of our then-market capitalization.

Table of Contents
In September 2020, the compensation and talent management committee reviewed our compensation peer group and, upon the recommendation of its compensation consultant, added Ansys, Coupa Software, Fortinet, Intuit, Synopsys and The Trade Desk to the compensation peer group and removed Dropbox, Guidewire Software, Hubspot, New Relic, Paylocity Holding, Proofpoint and Zendesk. The peer group for 2021, which was approved by the compensation and talent management committee in September 2020, consisted of the following companies:
AnsysIntuitShopifyVeriSign

performance.
Our compensation and talent management committee uses data drawn from our compensation peer group, as well as data from the Radford Global Technology executive compensation survey (the “
Radford Survey
”), to evaluate the competitive market when formulating its recommendation for the total direct compensation packages for our executive officers, including base salary and long-term incentive compensation opportunities. The Radford Survey provides compensation market intelligence and is widely used within the technology industry.
In addition, subsets of the Radford Survey were incorporated into the competitive assessment prepared by Compensia and used by our compensation and talent management committee to evaluate the compensation of our executive officers. Specifically, our compensation and talent management committee received a custom report of survey results reflecting only companies from our compensation peer group in addition to survey results tailored solely based on revenue. The Radford Survey data supplements the compensation peer group data and provides additional information for our named executive officers and other executive positions for which there is less comparable public data available.
Individual Compensation Elements
In 2021, the principal elements of our executive compensation program, and the purposes for each element, were as follows:

Also designed to achieve our retention objectives for our executive officers.

Base Salary
Base salary represents the fixed portion of the compensation of our executive officers, including our named executive officers, and is an important element of compensation intended to attract and retain highly talented individuals.
Using the competitive market data provided by its compensation consultant, our compensation and talent management committee reviews and develops recommendations for adjusting the base salaries for each of our executive officers, including our named executive officers, as part of its annual executive compensation review. In addition, the base salaries of our executive officers may be adjusted by our compensation and talent management committee in the event of a promotion or significant change in responsibilities.
Generally, our compensation and talent management committee sets base salaries with reference to various percentile levels of the competitive range of our compensation peer group and applicable executive compensation survey data. Since our initial public offering, we have evaluated the base salaries of our executive officers in the context of establishing their total cash compensation at levels that are consistent with the target total cash compensation of executive officers holding comparable positions at public companies.
In 2021, consistent with the recommendation of our Chief Executive Officer, our compensation and talent management committee determined to increase the base salaries of our executive officers other than our Chief Executive Officer. In making these decisions, our compensation and talent management committee considered the current risks and challenges facing our company, our decision to forego the adoption of an annual cash bonus program, its objective of gradually positioning the target total cash compensation of our executive officers at levels that are more consistent with those of a public company in our industry, as well as the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above. We recognize that our Chief Executive Officer’s base salary is significantly lower than the peer group median, despite his success in the role and our willingness to pay him a market-based salary. However, at our Chief Executive Officer’s request to weight more of his target total direct compensation to variable pay in the form of long-term incentive compensation, our compensation and talent management committee determined to maintain his base salary at its 2019 and 2020 levels, other than a nominal increase for rounding purposes.
The base salaries of our named executive officers for 2020 and 2021 (effective January 1, 2021) were as follows:

The actual base salaries paid to our named executive officers in 2021 are set forth in the “Summary Compensation Table” below.
Cash Incentives
As our Chief Revenue Officer, Mr. Boroditsky’s responsibilities are focused on sales and his compensation includes participation in our sales commission plan (the “
Sales Commission Plan
”) with terms that are aligned with the results achieved by our global sales team.
For fiscal 2021, after considering competitive market data in consultation with a leading third-party consultancy for sales compensation, Mr. Boroditsky’s commission opportunity for fiscal 2021 was determined to be equal to 100% of his annual base salary, consistent with his opportunity for the prior fiscal year. The Sales Commission Plan is designed to reward Mr. Boroditsky based on annual performance of total estimated annual recurring revenue (“
eARR
”), software eARR and company revenue metrics, paid monthly. Mr. Boroditsky’s monthly payouts are based on performance against the annual target, additive, with no cap. The performance target levels for Mr. Boroditsky were designed to be challenging to achieve. The Sales Commission Plan and performance criteria are evaluated annually with an eye to reducing risks while appropriately incentivizing performance.
Long-Term Incentive Compensation
We view long-term incentive compensation in the form of equity awards as a critical element of our executive compensation program. The realized value of these equity awards bears a direct relationship to our stock price, and, therefore, these awards are an incentive for our executive officers, including our named executive officers, to create value for our stockholders. Equity awards also help us retain qualified executive officers in a competitive market.
Long-term incentive compensation opportunities in the form of equity awards are granted by our compensation and talent management committee on a regularly-scheduled basis, as described in “Other Compensation Policies and Practices—Equity Awards Grant Policy” below. The amount and forms of such equity awards are determined by our compensation and talent management committee after considering the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above. The amounts of the equity awards are also intended to provide
competitively-sized
awards and resulting target total direct compensation opportunities that are competitive with the compensation opportunities offered by the companies in our compensation peer group and Radford Survey data for similar roles and positions for each of our executive officers, taking into consideration the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above.
18

Table of Contents
In 2021, our compensation and talent management committee determined that the equity awards to be granted to our executive officers should be in the form of time-based stock options to purchase shares of our Class A common stock and time-based RSUs that may be settled for shares of our Class A common stock. Our compensation and talent management committee determined to grant equity awards in the form of 50% (by fair value) stock options and 50% (by fair value) time-based RSUs. Stock options only have value if our stock price appreciates above the exercise price thereof. Both stock options and RSUs have retention value over the vesting period. In determining the size of the individual grants to our executive officers, our compensation and talent management committee considered the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above, with emphasis on our exceptional growth in size and revenue during 2020. In addition, our compensation and talent management committee focused on the fact that many of our executive officers are in high demand in the market due, in part, to our excellent performance in 2020. Therefore, our compensation and talent management committee considered how best to retain our talent. In determining the size of the equity grants made to our Chief Executive Officer, the compensation and talent management committee also factored in Mr. Lawson’s relatively low base salary.
After consideration of these factors, our compensation and talent management committee determined to grant equity awards to our executive officers with a value in the range of the 70
th
percentile to the 85
th
percentile of our peer group range. Our compensation and talent management committee determined that the value of these awards was appropriate and necessary to sufficiently reward exceptional performance, to motivate our executive officers for continued effort to create value for our stockholders and to help ensure retention in a competitive market. Importantly, our compensation and talent management committee also determined to maintain the prior deviation from the historic vesting schedules for executive awards to balance the magnitude of the awards, and also to motivate long-term retention and team stability. Therefore, the stock options and RSUs granted to our executive officers in February 2021 vest over four years with 33% vesting in equal quarterly installments between the first and second anniversaries of the vesting commencement date of December 31, 2020, 33% vesting in equal quarterly installments between the second and third anniversaries of the vesting commencement date of December 31, 2020 and 34% vesting in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date of December 31, 2020, subject to the executive’s continued employment with us. In addition to the February 2021 grants, our compensation and talent management committee also granted equity awards to certain executive officers in 2021 in connection with new hires and promotions with specific vesting schedules, as described further in “Executive Compensation—Additional Executive Officer Awards” and “Executive Compensation—Grants of Plan-Based Awards Table” below.
After considering the factors described in “Oversight of Executive Compensation Program—Compensation-Setting Process” above, our compensation and talent management committee approved the following equity awards in February 2021 for our then-existing named executive officers in 2021 as part of its annual executive compensation review:

Mr. Chew’s employment at Twilio ended effective May 17, 2021. All unvested RSUs and unvested stock options expired immediately upon termination.
Additional Executive Officer Awards
Mr. Manor received a
(1) one-time
stock option award with a grant date fair value of $8,098,119 and
(2) one-time
restricted stock units award with a grant date fair value of $33,687,986 in connection with his commencement of employment with us in November 2021. The shares subject to the option vest over four years in equal monthly installments, and the RSUs vest over four years, with 1/16th of the RSUs vesting on February 15, 2022 and the remaining RSUs vesting in equal quarterly installments, in each case subject to continued employment with us.
Mr. Boroditsky received a
(1) one-time
stock option award with a grant date fair value of $5,158,566 and
(2) one-time
restricted stock units award with a grant date fair value of $5,131,560 in connection with his expanded role in his position as Chief Revenue Officer in October 2021. The shares subject to this option vest in 24 equal monthly installments, and the RSUs vest over two years, with 1/8th of the RSU vesting on November 15, 2021 and the remaining RSUs vesting in equal quarterly installments, in each case subject to continued employment with us.
Mr. Shipchandler also received (1) a
one-time
stock option award with a grant date fair value of $2,303,576 and (2) a
one-time
restricted stock unit award with a grant date fair value of $2,231,126 in connection with this appointment as Chief Operating Officer, with vesting schedules consistent with his February 2021 awards. Mr. Wagner commenced employment with us in December 2021 and did not receive any equity awards in fiscal 2021, but was granted a new hire RSU award in January 2022 in accordance with his employment offer letter. Please see “Summary Compensation Table,” “Grants of Plan-Based Awards Table” and “Employment Agreements or Offer Letters with Named Executive Officers” below for additional information.
Stock Options
We believe that stock options provide a strong reward for growth in the market price of our common stock as their entire value depends on future stock price appreciation, as well as a strong incentive for our executive officers to remain employed with our Company as they require continued service to our Company through the vesting period. In 2021, the stock options to purchase shares of our Class A common stock that were granted by our compensation and talent management committee generally had a
10-year
term. To balance retention and incentive dynamics for the stock option grants made in February 2021, the vesting schedule for such grants were set as follows: 33% of the shares subject to the stock option vest in equal quarterly installments between the first and second anniversaries of the “vesting commencement date” (December 31, 2020), 33% of the shares subject to the stock option vest in equal quarterly installments between the second and third anniversaries of the vesting commencement date and 34% of
20

Table of Contents
the shares subject to the stock option vest in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date, subject to continued employment through each such vesting date. The options subject to Mr. Borodistky’s October 2021 grant expire three years from the date of his separation from service due to termination by the company without Cause or by Mr. Boroditsky for Good Reason, as those terms are defined in the Boroditsky Letter (as defined below), or 10 years from the date of the grant, whichever comes first.
Stock options granted by our compensation and talent management committee to newly-hired executives generally have had a
10-year
term and generally vested as to 25% of the shares subject to the stock option on the first anniversary of the employment commencement date and 1/48
th
of the shares subject to the stock option each month thereafter for the following three years, subject to continued service through each such vesting date. Effective February 1, 2022, and applicable retrospectively to affectedfull-time employees stock options previously granted to our executive officers vest in equal monthly installments from the applicable vesting commencement date, subject to the executive’s continued employment with us. Please see “Summary Compensation Table” and “Grants of Plan-Based Awards Table” below for additional information.
Time-Based RSUs
We believe time-based RSUs also provide a strong retention incentive for our executive officers, provide a moderate reward for growth in the value of our Class A common stock and, because they use fewer shares than stock options, are less dilutive to our stockholders. In 2021, similar to the stock option grants, in order to balance retention and incentive dynamics for the time-based RSU grants that may be settled in shares of our Class A common stock, the vesting schedule for such grants were set as follows: 33% of the shares subject to the award vest in equal quarterly installments between the first and second anniversaries of the “vesting commencement date” (December 31, 2020), 33% of the shares subject to the award vest in equal quarterly installments between the second and third anniversaries of the vesting commencement date and 34% of the shares subject to the award vest in equal quarterly installments between the third and fourth anniversaries of the vesting commencement date, subject to continued employment through each such vesting date.
Time-based RSUs that may be settled in shares of our Class A common stock that were granted by our compensation and talent management committee to newly-hired executives generally vested as to 25% of the shares subject to the award on the first anniversary of the first August 15, November 15, February 15 or May 15 to occur following the employment commencement date and 1/16
th
of the shares subject to the award each quarter thereafter for the following three years, subject to continued employment through each such vesting date. Effective February 1, 2022, and applicable retrospectively to affected employees, RSUs granted to new executive officers vest in equal quarterly installments from the applicable vesting commencement date, subject to the executive’s continued employment with us.
The equity awards granted to our named executive officers in 2021 are set forth in the “Summary Compensation Table” and the “Grants of Plan-Based Awards Table” below.
Health and Welfare Benefits
Our executive officers, including our named executive officers, are eligible to receive, the same employee benefits that are generally available to all of our full-time employees, subject to the satisfaction of certain eligibility requirements. Theserequirements, our comprehensive benefits include ourpackage that includes medical, dental and vision insurance and life and disability insurance plans. In addition, we provide time off and we maintain a tax-qualified 401(k) retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. In 2023, we matched 50% of the first 6% of contributions by plan participants, subject to annual contribution limits set forth in the Internal Revenue Code of 1986, as amended.
In structuring these benefit plans, we seek to provide an aggregate level of benefits that are comparable to those provided by similar companies.

Code of 1986, as amended (the “
Code
”). In 2021, we matched 50%Global economic and business activities continue to face widespread macroeconomic uncertainties, including changes in the labor market and supply chain disruptions, inflation and monetary supply shifts, volatility in the banking and financial services sectors, and recession risks, which may continue for an extended period. Additionally, the instability in the geopolitical environment in many parts of the first 6% of contributions by plan participants, subject to annual contribution limits set forthworld, including from the war in Ukraine and conflict in the Code. WeMiddle East, may continue to cause or exacerbate uncertain economic conditions. These macroeconomic conditions have resulted in, and may continue to result in, decreased business spending by our current and prospective customers and business partners, reduced demand for or usage of our products, lower renewal rates by our customers, longer or delayed sales cycles, including current and prospective customers delaying contract signing or contract renewals, reduced budgets or minimum commitments related to the products that we offer, or delays in customer payments or our ability to make discretionary contributions tocollect accounts receivable, all of which could have an adverse impact on our business, results of operations and financial condition.

The current macroeconomic environment has constrained the Section 401(k) plan but have not done so to date. The Section 401(k) plan is intended to be qualified under Section 401(a)budgets and financial resources of the Code with the plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a
tax-qualified
retirement plan, contributions to the Section 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the Section 401(k) plan.
Perquisites and Other Personal Benefits
Currently, we do not view perquisites or other personal benefits as a significant componentsome of our executive compensation program. Accordingly, we do not provide significant perquisites current and prospective customers, which has caused them to become more budget-conscious and to delay and/or other personal benefitsreduce spending. Given that a majority of our revenue is usage-based and impacted by general consumer sentiment and activity, our business may be more immediately and severely impacted by adverse macroeconomic conditions than those that rely primarily on software-as-a-service (“SaaS”) subscription revenue. The current macroeconomic environment has caused certain of our Communications customers to reduce or terminate their usage of our executive officers, including our named executive officers, except as generally made available to our employees,products without notice or termination charges, which has negatively impacted, and, despite recent stabilization in situations where we believe it is appropriate to assist an individualusage volumes, may in the performancefuture negatively impact, our Communications revenue. Similarly, the current macroeconomic environment has caused certain of his or her duties,our Segment and other subscription-based customers to award long-standing servicerenegotiate existing contracts on less advantageous terms to us than those currently in place, reduce or limit their contract value, default on payments due on existing contracts, or fail to makerenew at the end of their current contract term, which has had, and may continue to have, a negative impact on our executive officers more efficientrevenue. A prolonged economic slowdown could exacerbate these negative effects on revenue and effectiverevenue growth in both our Communications and for recruitment and retention purposes.
During 2021, noneSegment business units. Additionally, when customers fail to pay us or reduce their spending with us, we may be adversely affected by an inability to collect amounts due, the costs of enforcing the terms of our named executive officers received perquisites contracts, including through litigation, and/or other personal benefits that were,a reduction in the aggregate, $10,000 or more for each individual, except for Mr. Lawson,revenue. For example, in February 2023, one of our Chief Executive Officer, for whom we paid $3,350 for our matching contributions to his Section 401(k) accountcustomers, Oi SA, a Brazilian telecom company, initiated reorganization proceedings in 2021, and his $280,000 filing fee under HSR,a Brazilian bankruptcy court as well as $5,595a secondary proceeding under Chapter 15 in the United States and $275,335, respectively, forexposed us to risks on collections of pre-petition receivables and ongoing revenue.

Many of our customers are in industries that have been negatively impacted by recent macroeconomic conditions, including customers in social media, cryptocurrencies, retail and e-commerce, consumer packaged goods, direct-to-consumer and other industries dependent on consumer spending, and the related legal feesconcentration of our customer base within these industries could exacerbate the effects of weakening macroeconomic conditions on our business. For example, we have experienced declines in usage of our Communications products by customers in industries negatively impacted by macroeconomic conditions which, despite recent stabilization in usage volumes, could reoccur or worsen in the future. We have also generally experienced, and tax
gross-up.
We believe that reimbursing our Chief Executive Officer for the HSR filing fee and its related legal fees and tax consequences was consistent with our decisionexpect to continue to compensate him almost entirely through equity-compensation arrangements. Absentexperience to varying degrees, longer sales cycles when engaging with current and potential customers in such industries. Our customers include many small and medium-sized businesses, which have been, and may continue to be, adversely affected by the macroeconomic conditions and uncertainties to a greater extent than larger enterprises with greater financial resources. If the effects of the current macroeconomic environment continue to adversely affect our business and the businesses of our current and prospective customers, our results of operations and financial condition may continue to be harmed, and many of the other risks described in this regulatory filing,“Risk Factors” section will be exacerbated.
Our quarterly and annual results of operations have fluctuated in the past and may continue to do so in the future. As a result, we may fail to meet securities analysts’ and investors’ expectations, which could cause the price of our Chief Executive Officer wouldcommon stock to decline.
Our quarterly and annual results of operations have fluctuated in the past and may continue to do so in the future due to a variety of factors, many of which are outside of our control. These fluctuations and the related impacts to any earnings guidance we may issue from time to time could cause the price of our common stock to change significantly or experience declines. In addition to the other risks described in this “Risk Factors” section, some of the factors that may result in fluctuations to our results of operations include:
13



fluctuations in demand for, pricing of, or usage of, our products, including due to the effects of global macroeconomic conditions, competition, and differing levels of demand for our products based on changing customer priorities, resources, financial conditions and economic outlook;
general economic conditions, including a downturn or recession, rising inflation and interest rates, and geopolitical uncertainty and instability;
changes in the organization of our business units;
the amount and timing of costs, and any adverse effects associated with, our workforce reductions;
our ability to attract and retain new customers, obtain renewals from existing customers and cross-sell or otherwise increase revenue from existing customers;
our ability to introduce new products and enhance existing products;
our ability to leverage more of our self-service capabilities for customers;
competition and the actions of our competitors, including pricing changes and the introduction of new technologies, products, services and geographies;
significant security breaches or incidents impacting our platform, or interruptions to the delivery and use of our products;
changes in cloud infrastructure, network services and other third-party technology, including the fees charged by their providers;
the productivity of our sales force;
the length and complexity of the sales cycle for certain of our products or customers;
changes in the mix of products that our customers use during a particular period;
seasonal trends in consumer activity;
changes in the mix or amount of products sold in the United States versus internationally;
the amount and timing of operating costs and capital expenditures related to the operations and expansion of our business;
expenses in connection with mergers, acquisitions, dispositions, or other strategic transactions;
the timing of customer payments and our ability to collect accounts receivable from customers;
increases in inflation and our ability to control costs, including our operating expenses;
the amount and timing of costs associated with recruiting, training and integrating new employees, and retaining existing employees;
changes in foreign currency exchange rates and our ability to effectively hedge our foreign currency exposure;
extraordinary expenses such as litigation or other dispute-related settlement payments;
changes in laws, industry standards and regulations that affect our business;
sales tax and other tax determinations by authorities in the jurisdictions in which we conduct business;
the impact of new accounting pronouncements; and
14



fluctuations in stock-based compensation expenses.
The occurrence of one or more of the foregoing and other factors may cause our results of operations to vary significantly. As such, comparing our operating results on a period-to-period basis may not be able to participatemeaningful and should not be relied upon as an indication of future performance. In addition, a significant percentage of our operating expenses is fixed in our long-term incentive compensation programnature and therefore, we determined that it was appropriate for us to reimburse him for this filing fee and any related tax liabilities.
In the future, we may provide perquisites or other personal benefits in limited circumstances. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by our compensation and talent management committee.
Post-Employment Compensation Arrangements
We believe that having in place reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly qualified executive officers. In connection with our initial public offering in 2016, we adopted an executive severance plan (as amended and restated in June 2017, the “
Amended and Restated Executive Severance Plan
”) to provide more standardized severance payments and benefits to our executive officers. In March 2018, we divided our Amended and Restated Executive Severance Plan into three separate plans, which we further amended in March 2022. Our three plans currently apply to our Chief Executive Officer (the “
CEO Severance Plan
”), our key executive officers and senior vice-president level employees (the “
Key Executive Severance Plan
”, together with our CEO Severance Plan, the “
Executive Severance Plans
”) and our vice president-level employees (the “
VP Severance Plan
”). Our Chief Executive Officer participates in the CEO Severance Plan and our other named executive officers participate in the Key Executive Severance Plan.
The Executive Severance Plans, as discussed in more detail in “Potential Payments Upon Termination or Change in Control—Executive Severance Plans” below are designed to help ensure the continued service of key executive officersis based on forecasted revenue trends. Accordingly, in the event of a potential acquisition,revenue shortfall, we may not be able to mitigate the negative impact on our net income (loss) and margins in the short term. If we fail to meet or exceed the expectations of investors or securities analysts, then the trading price of our common stock could fall substantially, and we could face costly lawsuits, including securities class action suits, which, in turn, could harm our business, results of operations and financial condition.
Actions that we are taking to restructure our business in alignment with our strategic priorities may not be as effective as anticipated.
In December 2023, we reduced our workforce by approximately 5%, after reducing our workforce by approximately 11% and approximately 17% in September 2022 and February 2023, respectively. While our reductions in force and other efforts to restructure our business were designed to streamline operations, reduce operating costs, improve operating margins, and realign our selling capacity, we may encounter challenges in the execution of these efforts that could prevent us from recognizing the intended benefits of such efforts or otherwise adversely affect our business, results of operations and financial condition.
As a result of the reductions in force, we have incurred, and may continue to incur, additional costs in the short term, including cash expenditures for employee transitions, notice period and severance payments, employee benefits and related facilitation costs, as well as non-cash expenditures related to vesting of share-based awards. These additional cash and non-cash expenditures could have the effect of reducing our operating margins. Our reductions in force may result in unintended consequences, including employee attrition beyond our intended reduction in force; damage to our corporate culture and decreased employee morale among our remaining employees; diversion of management attention; damage to our reputation as an employer, which could make it more difficult for us to hire new employees in the future; and the loss of institutional knowledge and expertise of departing employees. If we experience any of these adverse consequences, our reductions in force and other restructuring efforts may not achieve or sustain their intended benefits, or the benefits, even if achieved, may not be adequate to meet our long-term profitability and operational expectations, which could adversely affect our business, results of operations and financial condition. In addition, our reductions in force and other restructuring efforts could lead us to fail to meet, or cause delays in meeting, our operational and growth targets. While positions have been eliminated, functions that they performed remain necessary to our operations, and we may be unsuccessful in effectively and efficiently distributing the duties and obligations of departed employees among our remaining employees. The reduction in our workforce could also prevent us from pursuing new opportunities and initiatives or require us to adjust our growth strategy. As part of our reductions in force, we have reduced the size of our sales force to drive further efficiencies in our sales operations. With a smaller workforce, we are relying more heavily on our self-service model to drive sales of our Communications products to customers that do not require direct account coverage. Our self-service capabilities may not be as successful as we anticipate, and similarly, our efforts to accelerate Segment sales may not be effective or may take longer than we expect to drive growth. If we experience any of these adverse consequences, our reductions in force and other restructuring efforts may not achieve or sustain their intended benefits, or the benefits, even if achieved, may not be adequate to meet our long-term profitability and operational expectations, which could adversely affect our business, results of operations and financial condition.
As we continue to identify areas of cost savings and operating efficiencies, we may consider implementing further measures to reduce operating costs and improve operating margins. We may not be successful in implementing such initiatives, including as a result of factors beyond our control. If we are unable to realize the anticipated savings and efficiencies from our reductions in force, other restructuring efforts and future strategic initiatives, our business, results of operations and financial condition could be harmed.

In the first quarter of 2023, we reorganized our business into business units, and we have since adopted a two-segment reporting structure and further modified our business units and reporting segments. These changes may be disruptive to our business and may not have the desired effects.
In the first quarter of 2023, we reorganized our business into two business units—Communications and Data & Applications—to enable us to develop the organization and systems to successfully operate a multi-product business and to better align our sales resources with customer and market opportunities. In addition, as the business units were created based on how management views and evaluates our business, beginning with the quarter ended June 30, 2023, we changed our operating and reporting segment structure from one reportable segment to two reportable segments and revised our prior period presentation to conform to the new segments. In the fourth quarter of 2023, we modified the organization of our business units by moving Flex and Marketing Campaigns from Data & Applications to Communications, and we subsequently renamed Data & Applications to Segment.
Our business unit reorganization and changes in our segment reporting structure have required, and will continue to require, significant expenditures, allocation of valuable management resources, and significant demands on our operational and financial infrastructure. This could lead to a number of risks, including: actual or perceived disruption of service or reduction in service standards to our customers; the failure to preserve adequate internal controls as we reorganize our general and administrative functions, including our information technology and financial reporting infrastructure; the failure to preserve partnership, sales and other important relationships and to resolve conflicts that may arise; loss of sales as we eliminate certain sales positions, reorganize our sales teams into business units, and improve and expand our use of self-service capabilities; failure to develop effective cross-selling motions between the businesses; failure of the business units to drive efficiencies and leverage; diversion of management attention from ongoing business activities and core business objectives in order to manage operational changes; and the failure to maintain our corporate culture, employee morale and productivity, and to retain highly skilled employees due to reductions in our workforce and changes in leadership structure. Because of these and other factors, we cannot predict whether we will realize the purpose and anticipated benefits of our business reorganizations and segment reporting changes, and any similar changes in the future, and if we do not, our business, results of operations and financial condition could be adversely affected.
We are currently conducting an operational review of our Segment business, which we expect to complete in March 2024 and which could result in further changes to our Segment business.
There is no guarantee that investors, analysts or the market will understand or favorably view the changes we make to our financial reporting in connection with the shift from one to two segments or that any such changes will have the desired effect. Failure of investors or analysts to understand our revised segment reporting structure may negatively affect their ability to understand our business and operating results, which could adversely affect our stock price. In addition, we test for goodwill impairment at the reporting unit level and consider the difference between the fair value of a reporting unit and its carrying value when determining whether any impairment exists. There can be no assurance that changes to our segment reporting structure and business units will not result in impairment charges in future periods, which could harm our operating results.
Our business depends on customers increasing their use of our products, and a loss of customers or decline in their use of our products could adversely affect our business, results of operations and financial condition.
Our revenue grows as customers increase their usage of a product, extend their usage of a product to new applications or adopt a new product that we offer. The majority of our revenue is usage-based and our ability to grow and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with existing customers and to have them increase their usage of our products. If our customers do not increase their use of our products, then our revenue may decline or grow at rates lower than expected. Most of our usage-based customers do not have long-term contractual financial commitments to us and, therefore, may reduce or cease their use of our products at any time without penalty or termination charges. Our subscription-based customers generally base their contract value on anticipated usage, and if their anticipated levels of usage are not met, they may reduce their contract value or choose not to renew their contract upon its expiration.
Customers may terminate or reduce their use of our products for any number of reasons, including dissatisfaction with our products or with the value proposition of our products, our inability to meet their needs and expectations, their use of competitors’ products, macroeconomic conditions, or reductions in their budgets. Additionally, prior instances of disruptions in our cloud communications platform impacted our customers’ ability to use products on our platform for up to several hours at a time. Issues with our products have caused, and may in the future cause, us to incur certain costs associated with offering credits to our affected customers, which have had, and in the future may have, an adverse impact on customer satisfaction and our ability to retain or attract customers.
16



Additionally, we believe our ability to provide reasonable compensationcustomers with high-quality, effective customer support services at all stages of the process is a crucial component of maintaining customer satisfaction, generating increased customer usage of our products and ultimately retaining customers. If we are unable to executive officers who leaveeffectively assist our employ under specified circumstancescustomers, it could adversely affect our ability to retain existing customers and could disincentivize prospective customers from adopting our products. The resources we dedicate to customer service at a particular time may prove insufficient, such as in the event we are unable to respond quickly enough to accommodate short-term increases in demand for customer support. We also may be unable to modify the nature, scope and delivery of our customer support in order to compete with changes in the support services provided by our competitors. Our sales are highly dependent on our business reputation and on positive recommendations from our customers. If we are unable to provide high-quality customer support, or if there is a market perception that we do not maintain high-quality customer support, it could erode the trust of current and potential customers and adversely affect our reputation.
Customer usage of our products depends on factors generally outside of our control, including macroeconomic conditions, so it is difficult to accurately predict customers’ usage levels. The loss of customers or reductions in their usage levels of our products may each have a negative impact on our business, results of operations and financial condition. Our Dollar-Based Net Expansion Rate has recently declined as compared to prior periods, and it may continue to decline in the future if customers are not satisfied with our products and related customer service experience, the value proposition of our products or our ability to meet their needs and expectations, or due to macroeconomic conditions or reductions in customers’ budgets. If a significant number of customers cease using, or reduce their usage of our products, including due to cost-saving measures in the face of macroeconomic uncertainty or changes in the competitive landscape, then we may be required to spend significantly more on sales and marketing than we currently expect in order to maintain or increase revenue from customers. Such additional sales and marketing expenditures could adversely affect our business, results of operations and financial condition.
If we are unable to attract new customers or sell additional products to our existing customers in a cost-effective manner, our business, results of operations and financial condition would be adversely affected.
To grow our business, we must continue to attract new customers in a cost-effective manner, increase revenue from existing customers, and increase gross profits, each of which depends in part on our ability to increase adoption and usage of our products, and successfully market new products, including products with higher gross margins, in a cost-effective manner. We use a variety of marketing channels to promote our products and platform, such as developer events and developer evangelism, search engine marketing and optimization, regional customer events, email campaigns, billboard advertising and public relations initiatives. If the costs of the marketing channels we use increase, then we may choose to use alternative and less expensive channels, which may not be as effective as the channels we currently use. We have made in the past, and may make in the future, significant expenditures and investments of time and resources in new marketing campaigns and sales motions, and we cannot guarantee that any such investments will lead to wider adoption of our products or to the cost-effective acquisition of additional customers. In addition, new products that we develop may require increasingly sophisticated and more costly sales efforts and result in a longer sales cycle. If we are unable to maintain effective marketing programs, our ability to efficiently attract new customers could be adversely affected, and we may not be able to attract the number and types of new customers we are seeking. In addition, we are continuing to improve and expand our use of self-service capabilities, particularly for our Communications API customers, which may not be as effective as we anticipate in driving adoption or increased usage of our products. If we are unable to successfully increase adoption and usage of our existing and new products, or if our efforts to increase the usage of our products are more expensive or time-consuming than we expect, then our business, results of operations and financial condition would be adversely affected.
If we are unable to increase adoption of our products by enterprises, our business, results of operations and financial condition may be adversely affected.
Historically, a majority of our revenue has been generated as a result of software developers adopting our Communications API products through our self-service model. Our ability to increase our customer base, especially among enterprises, and achieve broader market acceptance of our products will depend, in part, on our ability to effectively organize, focus and train our sales, marketing and other employees. Our ability to convince enterprises to adopt our products will depend, in part, on our ability to attract and retain sales employees with experience selling to enterprises. We believe that there is significant competition for experienced sales professionals with the skills and technical knowledge that we require. Even if we are successful in hiring qualified sales employees, new hires require significant training and experience before they achieve full productivity, particularly for sales efforts targeted at enterprises and new territories. Our recent hires and planned hires may not become as productive as quickly as we expect, and we may encounter difficulties or be unable to hire or retain sufficient numbers of qualified individuals in the future in the markets where we do business. Because we do not have a long history of targeting our sales efforts at enterprises, we cannot predict whether, or to what extent, our sales will increase as we organize and train our sales force or how long it will take for sales employees to become productive.
17



As we seek to increase the adoption of our products by enterprises, including Segment and Engage, which are primarily aimed at complex customer data platform implementations at larger companies, we expect to incur higher costs and longer sales cycles. In the enterprise market segment, the decision to adopt our products may require the approval of multiple technical and business decision makers, including legal, security, compliance, procurement, operations and information technology (“IT”). In addition, while enterprise customers may quickly deploy our products on a limited basis, before they will commit to deploying our products at scale, they often require extensive education about our products and significant customer support time and also engage in protracted pricing and contract negotiations, which may be exacerbated by changing inflationary pressure and reduced IT budgets and may result in higher costs and longer sales cycles. In addition, sales cycles for enterprises are inherently more complex and less predictable than the sales through our self-service model, and some enterprise customers may not use our products enough to generate revenue that justifies the cost to obtain such customers. These complex and resource-intensive sales efforts could place additional strain on our product and engineering resources. Further, enterprises, including some of our existing customers, may choose to develop their own solutions that do not include our products. They may also demand reductions in pricing as their usage of our products increases, notwithstanding increased costs incurred by us to provide such products, which could have an adverse impact on our gross margin. Additionally, we have experienced, and may continue to experience, certain of our customers failing to renew their contracts with us, reducing or limiting their contract values, and engaging in longer sales cycles as these customers focus on general cost reductions in the face of macroeconomic uncertainty. As a result of our limited experience selling and marketing to enterprises, our efforts to sell to these potential customers may not be successful. If we are unable to increase the revenue that we derive from enterprises, then our business, results of operations and financial condition may be adversely affected.
Our future success depends, in part, on our ability to develop new products and product enhancements that achieve market acceptance, as well as adapt and respond effectively to rapidly changing technology and regulations, dynamic industry standards, and evolving interoperability requirements.
Our ability to attract new customers and increase revenue from existing customers depends in large part on our ability to enhance and improve our existing products and to alignintroduce compelling new products that reflect the interestschanging nature of our markets, technology, industry standards, and customer needs and preferences. The success of any enhancements or new products we introduce depends on several factors, including timely completion, adequate quality testing, actual performance quality, market-accepted pricing levels and overall market acceptance. Enhancements and new products that we develop may not be introduced in a timely or cost-effective manner, may contain errors or defects, may require reworking features and capabilities, may have interoperability difficulties with our platform or other products or may not achieve the broad market acceptance necessary to generate significant revenue or increase our gross profits. Furthermore, our ability to increase the usage of our products depends, in part, on the development of new use cases for our products, which is typically driven by our developer community and may be outside of our control.
The markets for our products, including the market for communications in general and cloud communications in particular, are subject to rapid technological change, evolving industry standards, and changing regulations, as well as changing customer needs, requirements and preferences. These are all uncertain and we cannot predict the consequences, effects, or introduction of new, disruptive, emerging technologies or the manner and pace at which our markets develop over time, and our ability to compete in these markets depends on predicting and adapting to these changing circumstances. The success of our business will depend, in part, on our ability to adapt and respond effectively to these changes on a timely basis, and anticipating these factors requires that we allocate significant resources without any guarantee that any such investments and efforts will result in initial or enhanced adoption of our products in the marketplace. For example, with the development of next-generation solutions that utilize new and advanced features, including AI and ML, we expect to commit significant resources to developing new products and enhancements incorporating AI and ML, and there is no guarantee that our investments and efforts will result in wider adoption of our products in the marketplace. If new technologies emerge that are able to deliver competitive products and services at lower prices, more efficiently, more conveniently or more securely or if new products are introduced into the market that could render our existing products obsolete, such technologies and products could adversely impact our ability to compete effectively and may lead to customers reducing or terminating their usage of our products. For example, if user authentication practices evolve to reduce or eliminate the use of one-time passwords, our revenue could be adversely affected.
Additionally, the success of our existing products and any new products we introduce depends, in part, on our ability to integrate them with third-party products used by us or our customers. The providers of such third-party products may modify the features, functionality, pricing, and other terms and conditions with respect to such products in a manner adverse to us and to our customers that use such third-party products in connection with our products. If we are unable to maintain the integrations between our products and such third-party products, our ability to meet the needs and expectations of our current and prospective customers could be adversely affected, which could adversely affect our business. Our platform must integrate with and leverage a variety of infrastructure, network, hardware, mobile and software platforms and technologies, and we need to continuously modify and enhance our products and platform to adapt to changes and innovation in these technologies. For

example, Apple, Google, Yahoo and other cell-phone operating system providers or inbox service providers have developed, and may in the future develop, new applications or functions intended to filter spam and unwanted phone calls, messages or emails. Third party platforms may also implement changes to their privacy policies or practices that may adversely impact us or our customers. In addition, our network service providers may adopt new filtering technologies in an effort to combat spam or robocalling. Such technologies may inadvertently filter desired messages or calls to or from our customers. If cell-phone operating system providers, network service providers, our customers or their end users adopt new software platforms or infrastructure, we may be required to develop new versions of our products to work with those new platforms or infrastructure. This development effort may require significant resources, which would adversely affect our business, results of operations and financial condition. Any failure of our products and platform to operate effectively with evolving or new platforms and technologies could reduce the demand for our products. If we are unable to respond to these changes in a cost-effective manner, our products may become less marketable and less competitive or obsolete, and our business, results of operations and financial condition could be adversely affected.
If we are unable to successfully and cost-effectively increase adoption and usage of our existing products, develop and drive adoption of new products, maintain integrations with third-party products, or anticipate and keep pace with changes in technology, customers’ needs, customers’ expectations, and industry standards, our business, results of operations and financial condition would be adversely affected.
The markets for our products continue to evolve and may decline or experience limited growth.
The markets for our products continue to evolve, which makes our business and future prospects difficult to evaluate. If current and prospective customers do not recognize the need for and benefits of our products and platform, they may decide to adopt alternative products and services to satisfy some portion of their business needs. In order to grow our business and extend our market position, we intend to focus on educating developers and enterprises about the benefits of our products and platform, expanding and improving the functionality of our products and bringing new technologies to market to increase market acceptance and use of our platform. Our growth will depend, in part, on our ability to expand the markets that our products address. Our ability to do so depends upon a number of factors, including the cost, performance and perceived value associated with such products and platform. The markets for our products and platform could fail to grow significantly, or at all, or there could be a reduction in demand for our products as a result of any number of factors, including a lack of customer acceptance, technological challenges, competing products and services, decreases in spending by current and prospective customers, weakening macroeconomic conditions, and other causes. If these markets do not experience significant growth or demand for our products decreases, then our business, results of operations and financial condition could be adversely affected.
If we fail to effectively manage our growth, then our business, results of operations and financial condition could be adversely affected.
Although we cannot provide any assurance that our business will continue to grow at the same rate or at all in the future, we have experienced substantial growth in our business and operations in recent years, which has placed, and may continue to place, significant demands on our management and our operational and financial resources, especially as we continue to focus on improving our operating efficiency. Although we have conducted workforce reductions in the past, we may experience employee growth in the future. We have also experienced significant growth in the number of customers, usage and amount of data that our platform and associated infrastructure support. As a result of this growth, our organizational structure is becoming more complex as we improve our operational, financial and management controls as well as our reporting systems and procedures. The expansion of our systems and infrastructure, as well as the changes arising from our business reorganizations, has required, and will continue to require, us to commit substantial financial, operational, and technical resources. Our revenue may not increase as a result of our investments in these areas and, if revenue does increase, it may not increase enough to offset these investments, or it may take several periods before we begin to see the benefits of these investments. If we are unable to adequately manage our growth and other business changes in a manner that preserves the key aspects of our corporate culture, including as a result of our past reductions in force and the reorganization of our business, the quality and performance of our products may suffer, which could negatively affect our brand, reputation and ability to retain and attract customers and employees. Finally, if we are unable to maintain reliable service levels for our customers or if the level of efficiency in our organization suffers as we grow and transform our operating model, then our business, results of operations and financial condition could be adversely affected.

We continue to scale the capacity of, and enhance the capability and reliability of, our technical infrastructure to support increased activity on our platform. Any failure to maintain performance, reliability, security, integrity and availability of our products and infrastructure to the satisfaction of our customers may harm our reputation and our ability to retain existing customers or attract new customers. If we fail to efficiently scale and manage our infrastructure, or if our customers experience service disruptions or outages, our business, financial condition and operating results may be adversely impacted.

The markets in which we participate are intensely competitive, and if we do not compete effectively, our business, results of operations and financial condition could be harmed.
The markets for our products are rapidly evolving, significantly fragmented and highly competitive, with relatively low barriers to entry in some segments. The principal competitive factors in our market include completeness of offering, credibility with customers, global reach, ease of integration and programmability, product features, platform scalability, reliability, deliverability, security and performance, brand awareness and reputation, the strength of sales and marketing efforts, customer support, and the cost of deploying and using products. In our Communications business, our competitors are primarily (i) CPaaS companies that offer communications products and applications, (ii) other software companies that compete with portions of our communications product line, and (iii) regional network service providers that offer limited developer functionality on top of their own physical infrastructure. In our Segment business, our competitors are primarily (i) SaaS companies and marketing cloud platform vendors that offer bundled applications and platforms, (ii) CRM and customer experience vendors and (iii) standalone customer data platform vendors.
Some of our competitors and potential competitors are larger and have greater name recognition, longer operating histories, more established customer relationships, larger budgets, lower operating costs, and significantly greater resources than we do. As a result, our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards, customer requirements or changing economic conditions. Our competitors may also offer products or services that address one or a limited number of functions at lower prices, with greater depth than our products or in different geographies. Our current and potential competitors may develop and market new products and services with comparable functionality to our products, and this could lead to us having to decrease prices in order to remain competitive.
With the introduction of new products and services and new market entrants, we expect competition to intensify in the future. As we expand the scope of our products, we may face additional competition and, in some cases, may find our products in competition with those of our customers, which could cause them to replace our products with competitive offerings. If one or more of our competitors were to merge or partner with another of our competitors or our suppliers, the change in the competitive landscape could also adversely affect our ability to compete effectively. For example, certain of our competitors have engaged in acquisition activity and we expect that our competitors will continue to evaluate the acquisition of companies and technologies that could increase competition with our products in the future. In addition, some of our competitors have lower list prices than us, which may be attractive to certain customers even if those products have different or lesser functionality. Pricing pressures and increased competition generally could result in reduced revenue, reduced margins, increased losses or the failure of our products to achieve or maintain widespread market acceptance, any of which could harm our business, results of operations and financial condition.
Our business, results of operations and financial condition also depends, in part, on our ability to establish and maintain relationships through resellers, distributors, and strategic partners. A portion of our revenue is derived from sales made by these partners and any one of them may later decide to sell their own products or those of third parties that may be competitive with our products. A loss or reduction in sales of our products through these third-party intermediaries could adversely affect our revenue and other results of operations.
We have a history of losses and may not achieve or sustain profitability in the future.
We have incurred net losses in each year since our inception, including net losses of $1.0 billion, $1.3 billion and $949.9 million in the years ended December 31, 2023, 2022 and 2021, respectively. We had an accumulated deficit of $5.1 billion as of December 31, 2023. We will need to generate and sustain increased revenue levels, and manage our operating expenses, in future periods to become profitable and achieve our stated profitability goals and, even if we do, we may not be able to maintain or increase our level of profitability. We expect to continue to expend substantial financial and other resources on, among other things: investments in our engineering team; improvements in security and data protection; the development of new products, features and functionality and enhancements to our platform; sales and marketing; expansion of our operations and infrastructure, both domestically and internationally; and general administration, including legal, accounting and other expenses related to being a public company. Our efforts to grow our business may be more costly than we expect, and we may not be able to increase our revenue enough to offset our associated operating expenses. We may incur significant losses in the future for a number of reasons, including the other risks described herein, and unforeseen expenses, difficulties, complications and delays and other unknown events. If we are unable to achieve and sustain profitability, or if we incur significant losses, the value of our business and common stock may significantly decrease.
20



We depend largely on the continued services of highly skilled personnel, including our senior management and other key employees, and the inability to attract, integrate or retain such employees could adversely affect our business, results of operations and financial condition.
Our future performance depends on the continued services and contributions of highly skilled personnel, including our senior management and other key employees, to execute on our business plan, to develop our products and platform, to deliver our products to customers, to attract and retain customers and to identify and pursue opportunities to expand our business. We believe that there is, and will continue to be, intense competition for highly skilled management, technical, sales and other employees with experience in our industry. In addition, we have conducted reductions in force and experienced and may continue to experience employee attrition, which could significantly delay or prevent the achievement of our business objectives, and any resulting influx of new employees may require us to expend time, attention and resources to recruit and retain employees, restructure parts of our organization and train and integrate new personnel. If we fail to effectively manage attrition, and to hire, integrate and adequately incentivize our personnel, our efficiency and ability to meet our operational and growth targets, as well as our corporate culture, employee morale, productivity and retention, could suffer, and our business and operating results would be adversely impacted.
Additionally, loss of services of senior management or other key employees could significantly delay or prevent the achievement of our development and strategic objectives. In January 2024, our co-founder, Jeff Lawson, resigned as Chief Executive Officer and as a member of our board of directors, and Khozema Shipchandler, our former President, Twilio Communications, was appointed as Chief Executive Officer and as a member of our board of directors. We will incur various expenses in connection with the transition and we may face challenges in connection with the transition, such as potential changes to our strategy, corporate culture, and other changes in our management structure or roles. Any of our executive officers may terminate employment with us at any time with no advance notice. We have experienced, and may continue to experience, high attrition among our stockholders when consideringsenior management team and key employees. The replacement of any of our long-term future.
senior management or other key employees will involve significant time and costs, and any loss of services of any such key employee for any reason could significantly delay or prevent the achievement of our business objectives and could adversely affect our business, results of operations and financial condition.
The labor market for our business is subject to external factors that are beyond our control, including our industry’s highly competitive market for skilled workers and leaders. We must provide competitive compensation packages and a high-quality work environment to hire, retain and motivate employees. Volatility in, or the actual or perceived lack of performance of, our stock price may affect our ability to attract, motivate and retain key employees. In September 2022, February 2023 and December 2023, we implemented reductions in force, which may have an impact on our ability to hire, retain and motivate employees. If we are unable to retain and motivate our existing employees and attract qualified employees to fill key positions, we may be unable to manage our business effectively, including the development, marketing and sale of our products, which could adversely affect our business, results of operations and financial condition.
If we are not able to maintain and enhance our brand and increase market awareness of our company and products, then our business, results of operations and financial condition may be adversely affected.
We believe that maintaining and enhancing the severance payments“Twilio” brand identity and benefits providedincreasing market awareness of our company and products, particularly among developers and enterprises, is critical to achieving widespread acceptance of our platform, to strengthening our relationships with our existing customers and to our executive officers underability to attract new customers. The successful promotion of our brand will depend largely on our continued marketing efforts, our ability to continue to offer high-quality products, and our ability to successfully differentiate our products and platform from competing products and services. Our brand promotion and thought leadership activities may not be successful or yield increased revenue. In addition, independent industry analysts often provide reviews of our products and competing products and services, which may significantly influence the Executive Severance Plansperception of our products in the marketplace. If these reviews are appropriatenegative or not as strong as reviews of our competitors’ products and services, then our brand may be harmed.
The promotion of our brand also requires us to make substantial expenditures, and we anticipate that these expenditures will increase as our markets become more competitive and as we expand into new markets. To the extent that these activities increase revenue, this revenue still may not be enough to offset the increased expenses we incur.
21



To deliver our products, we rely on network service providers and internet service providers for our network service and connectivity, and disruption or deterioration in lightthe quality of these services or changes in network service provider fees that we pay in connection with the delivery of communications on our platform could adversely affect our business, results of operations and financial condition.
We currently interconnect with fixed and mobile network service providers around the world to enable the use by our customers of our products over their networks. Although we are in the process of acquiring authorization in many countries for direct access to phone numbers and for the provision of voice and messaging services on the networks of fixed and mobile network service providers, we expect that we will continue to rely on network service providers for these services. Where we do not have direct access to phone numbers, our reliance on network service providers has reduced our operating flexibility, ability to make timely service changes and control quality of service. In addition, the fees that we are charged by network service providers may change daily or weekly and we can be subject to the imposition of additional fees, penalties, or other administrative or technical requirements, and even service interruption, due to regulatory, competitive, or other industry related changes over which we have little to no control. We typically do not change our customers’ pricing as rapidly and, as a result, such fee increases could adversely affect our business and results of operations.
For example, in recent years, multiple major U.S. mobile carriers have introduced A2P SMS service offerings that added a new fee for A2P SMS messages delivered to their respective subscribers, and, from time to time, other U.S. mobile carriers have added similar fees. While we have historically responded to these types of fee increases through a combination of further negotiating efforts with our network service providers, absorbing the increased costs or passing the fees through to customers, there is no guarantee that we will continue to be able to respond in these ways in the future without a material negative impact to our business. Passing these fees through to our customers typically has the effect of increasing our Communications revenue and cost of revenue, but typically does not impact the gross profit dollars received for sending these messages and, as a result, has a negative impact on our gross margins. Additionally, our ability to respond to any new fees may be constrained if all network service providers in a particular market impose equivalent fee structures, if the magnitude of the post-employment compensation protections
fees is disproportionately large when compared to the underlying prices paid by our customers, or if the market conditions limit our ability to increase the price we charge our customers.
Furthermore, many of these network service providers do not have long-term committed contracts with us and may interrupt services or terminate their agreements with us without notice. If a significant portion of our network service providers stop providing us with access to their infrastructure, fail to provide these services to us on a cost-effective basis, cease operations, or otherwise terminate these services, the delay caused by qualifying and switching to other network service providers could be time consuming and costly and could adversely affect our business, results of operations and financial condition. Further, if problems occur with our network service providers, it may cause errors, service outages, or poor-quality communications on our products, and we could encounter difficulty identifying the source of the problem. The occurrence of errors, service outages, or poor-quality communications on our products, whether caused by our platform or a network service provider, may result in the loss of our existing customers or the delay of adoption of our products by potential customers and may adversely affect our business, results of operations and financial condition.

TableFurther, we sometimes access network services through intermediaries who have direct access to network service providers. Although we are in the process of Contents

These intermediaries sometimes have offerings that directly compete with our compensation peer groupproducts and are an important componentmay stop providing services to us on a cost-effective basis.

We also believe thatinterconnect with internet service providers around the occurrence orworld to enable the use of our email products by our customers, and we expect to continue to rely on internet service providers for network connectivity going forward. Our reliance on internet service providers reduces our control over quality of service and exposes us to potential service outages and rate fluctuations. The occurrence of a changepoor-quality of service or service outages on our products may result in control transaction will create uncertainty regarding the continued employmentloss of our executive officers. existing customers or the delay of adoption of our products by potential customers and may adversely affect our business, results of operations and financial condition. Similarly, if a significant portion of our internet service providers stop providing us with access to their network infrastructure, fail to provide access on a cost-effective basis, cease operations, or otherwise terminate access, the delay caused by qualifying and switching to other internet service providers could be time consuming and costly and could adversely affect our business, results of operations, and financial condition.
22



Failure to set optimal prices for our products could adversely impact our business, results of operations and financial condition.
For certain of our products, we primarily charge our customers based on their usage of such products. One of the challenges of this usage-based pricing model is the variability of the fees that we pay to network service providers over whose networks we transmit communications. Such network fees can vary daily or weekly and are affected by volume and other factors that may be outside of our control, and which are difficult to predict. This can result in us incurring increased costs that we may be unable or unwilling to pass through to our customers, which could adversely impact our business, results of operations and financial condition. If we elect to pass through increased fees to our customers, it could adversely affect our relationship with our customers and our customers may look for lower cost alternatives.
We adjust the pricing models for our products from time to time and expect that we will continue to do so. Many of our usage-based customers enter into contracts with negotiated pricing, and our subscription customers are also subject to negotiated pricing. As competitors introduce new products or services that compete with ours or reduce their prices, we may be unable to attract new customers or retain existing customers based on our historical pricing. If we are required or choose to reduce our prices, it could adversely affect our business, results of operations and financial condition.
Our international operations expose us to risks inherent in global operations.
In orderthe years ended December 31, 2023, 2022 and 2021, we derived 34%, 34% and 32% of our revenue from customer accounts located outside the United States, respectively. The future success of our business will depend, in part, on our ability to encourage themstrategically maintain and expand our customer base worldwide. Operating in international markets requires significant resources and management attention and subjects us to remain employed with us during an important time when their prospects for continued employment followingregulatory, economic and political risks in addition to those we face in the transaction are often uncertain, we provide our executive officers with the opportunity to receive additional severance protections during a change in control protection period. United States.
In addition, we provide additionalface risks in doing business internationally that could adversely affect our business, including:
inflation and actions taken by central banks to counter inflation;
the difficulty of managing and staffing international operations and the increased operations, travel, infrastructure and legal compliance costs associated with servicing international customers and operating numerous international locations;
our ability to effectively price our products in competitive international markets;
new and different sources of competition or other changes to our current competitive landscape;
potentially greater difficulty collecting accounts receivable and longer payment cycles;
higher or more variable network service provider fees outside of the United States;
the need to adapt and benefit protections iflocalize our products and support for specific countries;
understanding, reconciling, and implementing technical controls to address, different technical standards, data privacy and telecommunications regulations, and registration and certification requirements outside the United States, which could prevent customers from deploying our products or limit their usage;
our ability to comply with laws, regulations and industry standards relating to data privacy, data protection, data localization and data security, as well as sustainability and other ESG matters, enacted in countries and other regions in which we operate or do business, and the associated costs and management attention required to support such compliance;
difficulties in understanding and complying with local laws, regulations and customs in non-U.S. jurisdictions;
compliance with export controls and economic sanctions regulations administered by U.S. and foreign governmental entities in jurisdictions in which we operate, including the Department of Commerce's Bureau of Industry and Security and the Treasury Department’s Office of Foreign Assets Control;
23



compliance with various anti-bribery and anti-corruption laws such as the U.S. Foreign Corrupt Practices Act, as amended (“FCPA”) and United Kingdom Bribery Act of 2010;
changes in international trade policies, tariffs and other non-tariff barriers, such as quotas and local content rules;
more limited protection for intellectual property rights in some countries;
adverse tax consequences;
fluctuations in currency exchange rates, which could increase the price of our products outside of the United States, increase the expenses of our international operations and expose us to foreign currency exchange rate risk;
currency control regulations, which might restrict or prohibit our conversion of other currencies into U.S. dollars;
restrictions on the transfer of funds;
deterioration of political relations between the United States and other countries;
the impact of natural disasters and public health epidemics or pandemics such as COVID-19 on employees, contingent workers, partners, travel and the global economy and the ability to operate freely and effectively in a region that may be fully or partially on lockdown; and
political or social unrest, economic instability, conflict or war in a specific country or region in which we, our customers, partners or service providers operate, which could have an executive officer voluntarily terminates employmentadverse impact on our operations in the region or otherwise have a material impact on regional or global economies, any or all of which could adversely affect our business.
Also, due to costs from our international operations and network service provider fees outside of the United States, which generally are higher than domestic rates, our Communications gross margin for international customers is typically lower than our Communications gross margin for domestic customers. As a result, our Communications gross margin has been, and may continue to be, adversely impacted by our international operations. Our failure to manage any of these risks successfully could harm our international operations, and adversely affect our business, results of operations and financial condition.
We currently generate significant revenue from our largest customers, and the loss or decline in revenue from any of these customers could harm our business, results of operations and financial condition.
In the years ended December 31, 2023, 2022 and 2021, our 10 largest Active Customer Accounts generated an aggregate of 10%, 12% and 11% of our revenue, respectively. If any of these customers, or other large customers, do not continue to use our products, use fewer of our products, or use our products in a more limited capacity, or not at all, our business, results of operations and financial condition could be adversely affected. Additionally, the usage of our products by customers that do not have long-term contracts with us may change between periods. Those with no long-term contract with us may reduce or fully terminate their usage of our products at any time without notice, penalty or termination charges, which may adversely impact our results of operations.
We may not realize potential benefits from our acquisitions, partnerships and investments because of difficulties related to integration, the achievement of synergies, and other challenges.
We have acquired and invested in businesses and technologies that are complementary to our business through acquisitions, partnerships or investments, and we expect to continue to selectively evaluate strategic opportunities in the future. There can be no assurances that our businesses can be combined in a manner that allows for good reasonthe achievement of substantial benefits. Any integration process may require significant time and resources, and we may not be able to manage the process successfully as our ability to acquire and integrate larger or more complex companies, products, or technology in a successful manner is unproven. If we are not able to successfully integrate these acquired businesses with ours or pursue our customer and product strategy successfully, the anticipated benefits of such acquisitions may not be realized fully or may take longer than expected to be realized. Further, it is possible that there could be a loss of our key employees and customers, disruption of ongoing businesses or unexpected issues, higher than expected costs and an overall post-completion process that takes longer than originally anticipated. In addition, the following issues, among others, must be addressed in order to realize the anticipated benefits of our acquisitions, partnerships or investments:
24



combining the acquired businesses’ corporate functions with our corporate functions;
combining acquired businesses with our existing business in a manner that permits us to achieve the synergies anticipated to result from such acquisitions, the failure of which would result in the anticipated benefits of our acquisitions not being realized in the time frame currently anticipated or at all;
maintaining existing agreements with customers, distributors, providers, talent and vendors and avoiding delays in entering into new agreements with prospective customers, distributors, providers, talent and vendors;
determining whether and how to address possible differences in corporate cultures and management philosophies;
integrating the companies’ compliance, administrative and IT infrastructure;
developing products and technology that allow value to be unlocked in the future;
evaluating and forecasting the financial impact of such acquisitions, partnerships and investments, including accounting charges; and
effecting potential actions that may be required in connection with a change in controlobtaining regulatory approvals.
In addition, at times the attention of certain members of our Company,management and resources may be focused on integration of the acquired businesses and diverted from day-to-day business operations, which may disrupt our ongoing business.
We have incurred, and may continue to incur, significant, nonrecurring costs in connection with our acquisitions, partnerships and investments and integrating our operations with those of the acquired businesses, including costs to maintain employee morale and to retain key employees. Management cannot ensure that the elimination of duplicative costs or the realization of other efficiencies will offset the transaction and integration costs in the near term or at all.

From time to time we may also divest or stop investing in certain businesses or products. For example, in the second quarter of 2023, we sold our Internet of Things assets and liabilities, and in the third quarter of 2023, we sold our ValueFirst business. The sale of a business or product may require us to restructure operations and/or terminate employees, and could expose us to unanticipated ongoing obligations and liabilities, including as a result of our indemnification obligations. Additionally, such transactions could disrupt our customer, supplier and/or employee relationships and divert management and our employees’ time and attention. During the pendency of a divestiture, we may be subject to risks related to a decline in the business, loss of employees, customers, or suppliers, and that the transaction may not close, which could have an adverse effect on the business to be divested and on us. Additionally, we may experience harm to our financial results, including loss of revenue, and we may not realize the expected benefits and cost savings of these actions and our operating results may be adversely impacted.
Risks Related to Cybersecurity, Data Privacy and Intellectual Property
Breaches of or incidents impacting our networks or systems, or those of AWS or our service providers, could degrade our ability to conduct our business, compromise the integrity of our products, platform and data, result in significant loss or unavailability of data and the theft of our intellectual property, damage our reputation, expose us to liability to third parties and require us to incur significant additional costs to maintain the security of our networks and data.
We depend upon our IT systems to conduct virtually all of our business operations, ranging from our internal operations and research and development activities to our marketing and sales efforts and communications with our customers and business partners. We have in the past and may in the future be subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks (such as credential stuffing), personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss or unavailability of data or other information technology assets, adware, telecommunications failures, earthquakes, fires, floods, natural disasters, and other similar threats.
Individuals or entities may attempt to penetrate the security of our platform, or of our network or systems, and to cause harm to our business operations, including by misappropriating our proprietary information or that of our customers, employees and business partners or to cause interruptions of our products and platform. In particular, cyberattacks and other malicious internet-based activity continue to increase in frequency and in magnitude generally, and cloud-based companies have been
25



targeted in the past. In addition to threats from traditional computer hackers, malicious code, software vulnerabilities, supply chain attacks and vulnerabilities through our third-party partners, employees theft or misuse, password spraying, phishing, smishing, vishing, credential stuffing and denial-of-service attacks, we also face threats from sophisticated organized crime, nation-state, and nation-state supported actors who engage in attacks (including advanced persistent threat intrusions) that add to the risk to our systems (including those hosted on AWS or other cloud services), internal networks, our customers’ systems and the information that they store and process. Ransomware and cyber extortion attacks, including those perpetrated by organized criminal threat actors, nation-states, and nation-state-supported actors, are becoming increasingly prevalent and severe and can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate or reduce the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments. Because the techniques used to access, disrupt or sabotage devices, systems and networks change frequently and may not be recognized until launched against a target, we may be required to make further investments over time to protect data and infrastructure as cybersecurity threats develop, evolve and grow more complex over time. We may also be unable to anticipate these techniques, and we may not become aware in a timely manner of any security breach or incident, which could exacerbate any damage we experience.
Additionally, we depend upon our employees and contractors to appropriately handle confidential and sensitive data, including customer data, and to deploy our IT resources in a safe and secure manner that does not expose our network systems to security breaches or incidents or the loss, alteration, unavailability, or other unauthorized processing of data. We have been and expect to be subject to cybersecurity threats and incidents, including denial-of-service attacks, employee errors or individual attempts to gain unauthorized access to information systems. We also continue to incorporate AI solutions and features into our platform, which may result in security incidents or otherwise increase cybersecurity risks. Further, AI technologies may be used in connection with certain cybersecurity attacks, resulting in heightened risks of security breaches and incidents. Any data security incidents, including internal malfeasance or inadvertent disclosures by our employees or a third party’s fraudulent inducement of our employees to disclose information, unauthorized access or usage, the introduction of viruses or other malicious code or any other breach or incident or disruption of our platform, systems, or networks or those of our service providers, such as AWS, could result in loss, corruption, unavailability, or other unauthorized processing of confidential information, and any such event, or the perception that it has occurred, may result in damage to our reputation, erosion of customer trust, loss of customers, litigation, regulatory investigations, fines, penalties and other liabilities. For example, in June and August 2022, we became aware that threat actors had conducted sophisticated social engineering campaigns against some of our employees after having obtained employee names and cell phone numbers from unknown sources. The attack identified in August, which involved smishing text messages that purported to be from our IT department, resulted in the threat actor obtaining some of our employees’ credentials and access to certain data of approximately 209 customers out of our total customer base of approximately 270,000 at that time. We notified and worked with our affected customers. We also notified appropriate regulators and addressed their questions about the incident. We also took steps to remediate the incident, including enhancing our security training, improving our two factor authentication requirements, implementing additional layers of control within our VPN, reducing access to certain internal applications and tools, and increasing the refresh frequency for access to certain internal applications. Industry reports indicate that the threat actors also attacked other technology, telecommunication and cryptocurrency companies.
Furthermore, we are required to comply with laws and regulations that require us to maintain the security of personal information and we may have contractual and other legal obligations to notify customers, regulators, government agencies, impacted individuals or other relevant stakeholders of security breaches. Such disclosures are costly, and the disclosures or the failure to comply with such requirements could lead to adverse consequences. If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences. These consequences may include: government enforcement actions and other actions or proceedings (for example, investigations, audits, and inspections), and related fines, penalties, required remedial actions, or other obligations and liabilities; additional reporting requirements and/or oversight; restrictions on processing or transferring data (including personal data); claims, demands, and litigation (including class claims); indemnification obligations; monetary fund diversions; interruptions in our operations (including availability of data); financial loss and other similar harms. Actual and perceived security incidents and attendant consequences could also lead to negative publicity and reputational harm, may cause our customers to lose confidence in the effectiveness of our security measures and require us to expend significant capital and other resources to respond to and/or mitigate the security incident. Accordingly, if our cybersecurity measures or those of AWS or our service providers fail to protect against unauthorized access, attacks (which may include sophisticated cyberattacks), or if our employees or contractors compromise or mishandle data, then our reputation, customer trust, business, results of operations and financial condition could be adversely affected.
While we maintain errors, omissions and cyber liability insurance policies covering certain security and privacy damages, we cannot be certain that our existing insurance coverage will continue to be available on acceptable terms or will be
26



available, and in sufficient amounts, to cover the potentially significant losses that may result from a security incident or breach or that the insurer will not deny coverage as to any future claim.
Our actual or perceived failure to comply with increasingly stringent laws, regulations and contractual obligations relating to privacy, data protection and data security could harm our reputation and subject us to significant fines and liability or loss of business.
We and our customers are subject to numerous domestic (for example, the California Consumer Privacy Act of 2018 (“CCPA”)) and foreign (for example, the General Data Protection Regulation (“GDPR”) in the European Union (“EU”)) privacy, data protection and data security laws and regulations that restrict the collection, use, disclosure and processing of personal information, including financial and health data. These laws and regulations are expanding globally, evolving, are being tested in courts, may result in increasing regulatory and public scrutiny of our practices relating to personal information and may increase our exposure to regulatory enforcement action, sanctions and litigation. The breadth and depth of changes in data protection obligations has required significant time and resources, including a review of our technology and systems currently in use against the requirements of GDPR.
The CCPA (as amended by the California Privacy Rights Act of 2020) imposes obligations on businesses to which it applies. These obligations include, but are not limited to, providing specific disclosures in privacy notices and affording California residents (both consumers and employees) certain rights related to their personal information. The CCPA allows for statutory fines for noncompliance. Similar laws have been enacted or been proposed at the state and federal levels. For example, Connecticut, Utah, Virginia and Colorado have each passed laws similar to but different from the CCPA that took effect in 2023; Florida, Montana, Oregon and Texas have enacted similar legislation that becomes effective in 2024; Tennessee, Delaware, New Jersey and Iowa have passed such a law that will take effect in 2025; and Indiana has enacted similar legislation that will become effective in 2026. If we become subject to new privacy, data protection and data security laws, the risk of enforcement action against us could increase because we believemay become subject to additional obligations, and the number of individuals or entities that can initiate actions against us may increase, including individuals, via a voluntary terminationprivate right of employmentaction, and state actors.
Outside the United States, an increasing number of laws, regulations, and industry standards apply to privacy, data protection and data security. For example, the GDPR, the United Kingdom’s Data Protection Act 2018 (“UK GDPR”) and the new Swiss Federal Act on Data Protection, impose strict requirements for good reasonprocessing the personal information of individuals protected by the legislation, whether their data is essentially equivalentprocessed within or outside the European Economic Area (“EEA”), the United Kingdom (“UK”) and Switzerland, respectively (such jurisdictions, collectively, “Europe”). For example, the GDPR imposes significant requirements regarding the processing of individuals’ personal information, including in relation to transparency, lawfulness of processing, individuals’ privacy rights, compliant contracting, data minimization, data breach notification, data re-usage, data retention, security of processing and international data transfers. Under the GDPR and UK GDPR, government regulators may impose temporary or definitive bans on data processing or data transfers, require a company to delete data, as well as impose significant fines, potentially ranging up to 20 million Euros under the GDPR, 17.5 million GBP under the UK GDPR, or 4% of a company’s worldwide revenue, whichever is higher. Further, individuals may initiate compensation claims or litigation related to our processing of their personal information. Other privacy laws in Europe impose strict requirements around marketing communications and the deployment of cookies on users’ devices. As another example, Brazil’s General Data Protection Law (Lei Geral de Proteção de Dados Pessoais, or “LGPD”) (Law No. 13,709/2018) may apply to our operations. The LGPD broadly regulates processing of personal information of individuals in Brazil and imposes compliance obligations and penalties comparable to those of the GDPR. Additionally, we expect an involuntary terminationincrease in the regulation of employmentthe use of AI and ML in products and services. For example, in Europe, the proposed Artificial Intelligence Act (“AI Act”), once adopted, could impose onerous obligations related to the development, placing on the market and use of AI-related systems. We may have to change our business practices to comply with obligations under these or other new and evolving regimes.
Further, the interpretation and application of new domestic and foreign laws and regulations in many cases is uncertain, and our legal and regulatory obligations in such jurisdictions are subject to frequent and unexpected changes, including the potential for various regulatory or other governmental bodies to enact new or additional laws or regulations, to issue rulings that invalidate prior laws or regulations, or to increase penalties significantly. For example, the EU’s Digital Services Act, Digital Markets Act and Data Act recently entered into force. Also, the UK Parliament is currently debating the Data Protection and Digital Information (No. 2) Bill which, if enacted, will introduce certain changes to the UK’s data protection laws.
Similarly, with our registration as an interconnected VoIP provider for certain products with the Federal Communications Commission (“FCC”), we also must comply with privacy laws associated with customer proprietary network information rules in the United States. If we fail or are perceived to have failed to maintain compliance with these requirements,
27



we could be subject to regulatory audits, civil and criminal penalties, fines and breach of contract claims, as well as reputational damage, which could impact the willingness of customers to do business with us.
In addition to our legal obligations, our contractual obligations relating to privacy, data protection and data security have become increasingly stringent due to changes in laws and regulations and the expansion of our offerings. Certain privacy, data protection and data security laws, such as the GDPR and the CCPA, require our customers to impose specific contractual restrictions on their service providers. In addition, we support customer workloads that involve the processing of protected health information and are required to sign business associate agreements with customers that subject us to requirements under the federal Health Insurance Portability and Accountability Act of 1996, as amended by us without cause. The primary purposethe Health Information Technology for Economic and Clinical Health Act of 2009, as well as state laws that govern health information.
Our actual or perceived failure to comply with laws, regulations, contractual commitments, or other actual or asserted obligations, including certain industry standards, regarding privacy, data protection and data security could lead to costly legal action, adverse publicity, significant liability, inability to process data, and decreased demand for our services, which could adversely affect our business, results of operations and financial condition.
As a cumulative example of these arrangements is to keeprisks, because our most senior executive officers focused on pursuing potential corporate transactions thatprimary data processing facilities are in the best interests ofUnited States, we have experienced hesitancy, reluctance, or refusal by European or multinational customers to continue to use our stockholders regardless of whether those transactions may result in their own job loss. Reasonable post-acquisition payments and benefits should serveservices due to the interests of both the executive officer and our stockholders.
To protect our Company’s interests, we require all participants of the Executive Severance Plans to sign a standard form of general release in favor of the Company prior to receiving any severance payments or benefits under the applicable plan.
In addition, under the Executive Severance Plans, all payments and benefits provided in the event of a change in control of the Company are payable only if there is a qualifying loss of employment by a named executive officer (commonly referred to as a “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention value following a change in control of the Company and to avoid windfalls, both of which could occur if the vesting of equity awards accelerated automaticallypotential risks posed as a result of the transaction.Court of Justice’s July 2020 ruling in the “Schrems II” case, as well as related guidance from regulators and the recent enforcement action against Meta by the Irish Data Protection Commission. For example, absent appropriate safeguards or other circumstances, the GDPR and laws in Switzerland and the UK generally restrict the transfer of personal information to countries outside of the EEA, Switzerland and the UK such as the United States. On July 10, 2023, the European Commission adopted its adequacy decision for the EU-U.S. Data Privacy Framework. Based on this decision, personal information can flow from the EU to U.S. companies participating in the EU-U.S. Data Privacy Framework without having to put in place additional data protection safeguards. We are certified under the EU-U.S. Data Privacy Framework, the UK Extension to the EU-U.S. Data Privacy Framework, and the Swiss-U.S. Data Privacy Framework. If we cannot maintain a valid mechanism for cross-border data transfers, we and our customers may face increased exposure to regulatory actions, substantial fines, and injunctions against processing or transferring personal information from Europe or elsewhere. The inability to transfer personal information to the United States could significantly and negatively impact our business operations; limit our ability to collaborate with parties that are subject to data privacy and security laws; or require us to increase our personal information processing capabilities in Europe and/or elsewhere at significant expense. In addition, outside of Europe, other jurisdictions have proposed and enacted laws relating to cross-border data transfer or requiring personal information, or certain subcategories of personal information, to be stored in the jurisdiction of origin. If we are unable to increase our data processing capabilities and storage in Europe and other countries to limit or eliminate the need for data transfers out of Europe and other applicable countries quickly enough, and valid solutions for personal information transfers to the United States or other countries are not available or are difficult to implement in the interim, we will likely face continuing reluctance from European and multinational customers to use our services and increased exposure to regulatory actions, substantial fines and injunctions against processing or transferring personal information across borders.
Evolving laws, regulations, and other actual and asserted obligations relating to privacy, data protection, and data security, as well as any new or evolving obligations relating to the use of AI and ML technologies, could reduce demand for our platform, increase our costs, impair our ability to grow our business, or restrict our ability to store and process data or, in some cases, impact our ability to offer our service in some locations and may subject us to liability. Further, in view of new or modified federal, state or foreign laws and regulations, industry standards, contractual obligations and other actual and asserted obligations, or any changes in their interpretation, we may find it necessary or desirable to fundamentally change our business activities and practices or to expend significant resources to modify our practices and platform and otherwise adapt to these changes. We may be unable to make such changes and modifications in a commercially reasonable manner or at all, and our ability to develop new products and features could be limited.
We could incur substantial costs in protecting or defending our intellectual property rights, and any failure to protect our intellectual property could adversely affect our business, results of operations and financial condition.
Our success depends, in part, on our ability to protect our brand and the proprietary methods and technologies that we develop under patent and other intellectual property laws. We rely on a combination of patents, copyrights, trademarks, service marks, trade secret laws and other intellectual property laws, contractual provisions, and internal processes, procedures, and controls in an effort to establish, maintain, enforce, and protect our intellectual property and proprietary rights. However, the steps we take to protect our intellectual property may be inadequate. While we have been issued patents in the United States and other countries and have additional patent applications pending, we may be unable to obtain patent protection for the technology covered in our patent applications. In addition, any patents issued to us in the future may not provide us with
28



competitive advantages or may be successfully challenged by third parties. Further, the laws of some countries do not provide excise taxprotect intellectual property or proprietary rights to the same extent as the laws of the United States, and mechanisms for enforcement of such rights in some foreign countries may be inadequate. To the extent we expand our international activities, our exposure to unauthorized copying and use of our products and proprietary information may increase. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our technology and intellectual property.
We also rely, in part, on contractual confidentiality obligations we impose on our business partners, employees, consultants, advisors, customers and others in our efforts to protect our proprietary technology, processes and methods. These obligations may not effectively prevent unauthorized disclosure or use of our confidential information, and it may be possible for unauthorized parties to copy or access our software or other proprietary technology or information, or to develop similar products independently without us having an adequate remedy for unauthorized use or disclosure of our confidential information. In addition, others may independently discover our trade secrets and proprietary information, and in these cases, we may not be able to assert any trade secret rights against those parties.
We may be required to spend significant resources to monitor, enforce, maintain, and protect our intellectual property and proprietary rights. Litigation brought to protect and enforce our intellectual property or proprietary rights could be costly, time-consuming and distracting to management, result in a diversion of significant resources, or the narrowing or invalidation of portions of our intellectual property. Our efforts to enforce our intellectual property or proprietary rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of such rights. Our failure to meaningfully protect our intellectual property and proprietary rights, could have an adverse effect on our business, results of operations and financial condition.
We have been sued and may, in the future, be sued by third parties for alleged infringement of their intellectual or other proprietary rights, which could adversely affect our business, results of operations and financial condition.
There is considerable patent and other intellectual property development activity in our industry. We may also introduce or acquire new products or technologies, including in areas where we historically have not participated, which could increase our exposure to intellectual property infringement claims brought by third parties. Our future success depends, in part, on not infringing the intellectual property or proprietary rights of others and we may be unaware of such rights that may cover some or all of our technology or intellectual property. We have from time to time been subject to claims that our products or platform and underlying technology are infringing upon third-party intellectual property or proprietary rights. We may be subject to such claims in the future and we may be found to be infringing upon such rights. Any claims or litigation could cause us to incur significant expenses (including settlement payments (orand costs associated with litigation) and, if successfully asserted against us, could require that we pay substantial damages or ongoing royalty payments, prevent us from offering our products, or require that we comply with other unfavorable terms.
“gross-ups”Additionally, our agreements with customers and other third parties typically include indemnification or other provisions under which we agree to indemnify or are otherwise liable to them for losses suffered or incurred by them as a result of claims of intellectual property infringement. Although we typically limit our liability with respect to such obligations through such agreements, we may still incur substantial liability related to our indemnification obligations.
Regardless of the merits or ultimate outcome of any claims of infringement, misappropriation, or violation of intellectual or other proprietary rights that have been or may be brought against us or that we may bring against others, these types of claims, disputes, and lawsuits are time-consuming and expensive to resolve, divert management’s time and attention, and could harm our reputation. Litigation is inherently unpredictable and we cannot predict the timing, nature, controversy or outcome of disputes brought against us or assure you that the results of any of these actions will not have an adverse effect on our business, results of operations or financial condition.
Our use of open source software could negatively affect our ability to sell our products and subject us to possible litigation.
Our products and platform incorporate open source software, and we expect to continue to incorporate open source software in our products and platform in the future. Few of the licenses applicable to open source software have been interpreted by courts, and there is a risk that these licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products and platform. Although we have implemented policies to regulate the use and incorporation of open source software into our products and platform, we cannot be certain that we have not incorporated open source software in our products or platform in a manner that is inconsistent with such policies. If we fail to comply with open source licenses, we may be subject to certain requirements, including requirements that we offer our products that incorporate the open source software for no cost, that we make available the source code for any modifications or
29



derivative works we create based upon, incorporating or using the open source software and that we license such modifications or derivative works under the terms of applicable open source licenses. If an author or other third party that distributes such open source software were to allege that we had not, or have not, complied with the terms and conditions of the license for such open source software, we could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, enjoined from generating revenue from customers using products that contained the open source software and required to comply with onerous conditions or restrictions on these products. In any of these events, we and our customers could be required to seek licenses from third parties in order to continue offering our products and platform and to re-engineer our products or platform or discontinue offering our products to customers in the event re-engineering cannot be accomplished on a timely basis. Any of the foregoing could require us to devote additional research and development resources to re-engineer our products or platform, damage our reputation, give rise to increased scrutiny regarding our use of open source software, result in customer dissatisfaction and may adversely affect our business, results of operations and financial condition.
We rely on technology and intellectual property of third parties, the loss of which could limit the functionality of our products and disrupt our business.
We use technology and intellectual property licensed from third parties in certain of our products and our platform, and we expect to license additional third-party technology and intellectual property in the future. Licensed technology and intellectual property may not continue to be available on commercially reasonable terms, or at all. The loss of the right to license and distribute third-party technology could limit the functionality of our products or platform and could require us to redesign our products or platform. In addition, if the third-party technology and intellectual property we use has errors, security vulnerabilities, or otherwise malfunctions, the functionality of our products and platform may be negatively impacted, our customers may experience reduced service levels, and our business may be adversely affected.
For example, we outsource a substantial majority of our cloud infrastructure to AWS, which hosts our products and platform. Our customers need to be able to reliably access our platform, without material interruption or degradation of performance. AWS runs its own platform that we access, and we are, therefore, vulnerable to service interruptions at AWS. We have experienced, and expect that we may experience interruptions, delays and outages in service and availability in the future due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints. Capacity constraints could be caused by a number of potential causes, including technical failures, natural disasters, public health epidemics or pandemics, fraud or security attacks. In addition, if our security, or that of AWS, is compromised, our products or platform become unavailable, or if our users are unable to use our products within a reasonable amount of time or at all, any one of which may be due to circumstances beyond our control, then our business, results of operations and financial condition could be adversely affected. In some instances, we may encounter difficulties or otherwise not be able to identify the cause or causes of these performance problems within a period of time acceptable to our customers. It may become increasingly difficult to maintain and improve our platform performance and to troubleshoot performance issues, especially during peak usage times, as our products become more complex and the usage of our products increases. To the extent that we do not effectively address capacity constraints, either through AWS or alternative providers of cloud infrastructure, or through other factors that may result in interruptions, delays and outages in service and availability of our products and/or services, our business, results of operations and financial condition may be adversely affected. In addition, if Amazon.com, Inc. (“Amazon”) requires that we comply with unfavorable terms in order to continue our use of AWS or if Amazon implements any changes in its service levels for AWS, the changes may adversely affect our ability to meet our customers’ requirements, result in negative publicity which could harm our reputation and brand and may adversely affect the usage of our platform.
The substantial majority of the services we use from AWS are for cloud-based reserve service capacity and, to a lesser extent, storage and other optimization offerings. AWS enables us to order and reserve service capacity in varying amounts and sizes distributed across multiple regions. We access AWS infrastructure through standard IP connectivity protocols. AWS provides us with computing and storage capacity pursuant to an agreement that continues until terminated by either party. AWS may terminate the agreement if we fail to cure a breach of the agreement within 30 days of our being notified of the breach and, in some cases, AWS may suspend the agreement immediately for cause upon notice. Although we expect that we could procure similar services from other third parties, if any of our arrangements with AWS are terminated, we could experience interruptions to our platform and encounter difficulties in our ability to make our products reliably accessible by customers, as well as delays and additional expenses in procuring, implementing, and transitioning to alternative cloud infrastructure services. Any of the above circumstances or events may harm our reputation, erode customer trust, cause customers to stop using or reduce their usage of our products, discourage customers from renewing their contracts, impair our ability to increase revenue from existing customers, impair our ability to grow our customer base, subject us to financial penalties and liabilities under our service level agreements and otherwise harm our business, results of operations and financial condition.

The use of AI technologies in our platform and our business may not produce the desired benefits, and may result in increased liability, reputational harm, or other adverse consequences.
We continue to incorporate additional AI solutions and features into our platform and our business, including CustomerAI, and these solutions and features may become more important to our operations or to our future growth over time. We expect to rely on AI solutions and features to help drive future growth in our business, but there can be no assurance that we will realize the desired or anticipated benefits from AI. Our investments in AI solutions and features have and may continue to negatively impact our cost of revenue and gross margins, particularly for our Segment business, until we are able to increase revenue enough to offset these investments. We may also fail to properly implement or market our AI solutions and features. Our competitors or other third parties may incorporate AI into their products, offerings, and solutions more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our results of operations. Our ability to effectively implement and market our AI solutions and features will depend, in part, on our ability to attract and retain employees with AI expertise, and we expect significant competition for professionals with the skills and technical knowledge that we will require. Additionally, our offerings based on AI may expose us to additional claims, demands and proceedings by private parties and regulatory authorities and subject us to legal liability as well as brand and reputational harm. For example, our business, financial condition and results of operations may be adversely affected if content or recommendations that AI solutions or features assist in producing are or are alleged to be deficient, inaccurate, or biased, or if such content, recommendations, solutions, or features or their development or deployment (including the collection, use, or other processing of data used to train or create such AI solutions or features) are found to have or alleged to have infringed upon or misappropriated third-party intellectual property rights or violated applicable laws, regulations, or other actual or asserted legal obligations to which we are or may become subject. The legal, regulatory, and policy environments around AI are evolving rapidly, and we may become subject to new and evolving legal and other obligations. These and other developments may require us to make significant changes to our use of AI, including by limiting or restricting our use of AI, and which may require us to make significant changes to our policies and practices, which may necessitate expenditure of significant time, expense, and other resources. AI also presents emerging ethical issues, and if our use of AI becomes controversial, we may experience brand or reputational harm.
Risks Related to Legal and Regulatory Matters
Certain of our products are subject to telecommunications-related regulations, and future legislative or regulatory actions could adversely affect our business, results of operations and financial condition.
As a provider of communications products, we are subject to existing or potential FCC regulations relating to privacy, telecommunications, consumer protection and other requirements. In addition, the extension of telecommunications regulations to our non-interconnected VoIP services could result in additional federal and state regulatory obligations and taxes. We are also in discussions with certain jurisdictions regarding potential sales and other taxes for prior periods that we may owe. In the event any of these jurisdictions disagree with management’s assumptions and analysis, the assessment of our tax exposure could differ materially from management's current estimates, which may increase our costs of doing business and negatively affect the prices our customers pay for our services. If we do not comply with FCC rules and regulations, we could be subject to FCC enforcement actions, fines, loss of licenses and possibly restrictions on our ability to operate or offer certain of our products. For example, on January 25, 2023, we received a “cease-and-desist” letter from the FCC related to reported fraudulent traffic on our messaging platform. We subsequently removed the identified traffic. In response to written questions from the FCC, we sent a follow-up letter to the agency on February 10, 2023 detailing our fraud mitigation practices and various planned improvements to reduce future risks. There has been no further communication from the agency on this matter. Any enforcement action by the FCC, which may be a public process, would hurt our reputation in the industry, could erode customer trust, possibly impair our ability to sell our VoIP, other telecommunications products and/or other services to customers and could adversely affect our business, results of operations and financial condition.
Certain of our products are subject to a number of FCC regulations and laws that are administered by the FCC. Among others, we must comply (in whole or in part) with:
the Communications Act of 1934, as amended, which regulates communications services and the provision of such services;
the Telephone Consumer Protection Act, which limits the use of automatic dialing systems for calls and texts, artificial or prerecorded voice messages and fax machines;
the Communications Assistance for Law Enforcement Act, which requires covered entities to assist law enforcement in undertaking electronic surveillance;
31



requirements to safeguard the privacy of certain customer information;
payment of annual FCC regulatory fees and contributions to FCC-administered funds based on our interstate and international revenues; and
rules pertaining to access to our services by people with disabilities and contributions to the Telecommunications Relay Services fund.
In addition, Congress and the FCC are attempting to mitigate the prevalence of robocalls by requiring participation in a technical standard called Signature-based Handling of Asserted Information Using toKENs (“SHAKEN”) and Secure Telephone Identity Revisited (“STIR”) (together, “SHAKEN/STIR”), which allows voice carriers to authenticate caller ID, prohibiting malicious spoofing. The FCC also has open proceedings relating to robocalls and robotexts. While we do not currently expect the FCC to require more than the robocall and robotexting measures that we have started to implement, if the FCC were to implement new regulations or requirements that limited the types of customers allowed to use our platform or overly burdensome requirements for our customers, those actions could limit the customers that we are able to serve.
Similarly, in May 2021, the Biden Administration issued an Executive Order requiring federal agencies to implement additional information technology security measures, including, among other things, requiring agencies to adopt multifactor authentication and encryption for data at rest and in transit to the maximum extent consistent with Federal records laws and other applicable laws. The National Institute of Standards and Technology issued a Secure Software Development Framework (SSDF) on September 30, 2021 and Software Supply Chain Security Guidance (incorporating the SSDF), on February 4, 2022, and on March 7, 2022, the Office of Management and Budget directed federal agencies to incorporate both documents into their software lifecycle and acquisitions practices. The Executive Order also may lead to the development of additional secure software development practices and/or criteria for a consumer software labeling program, the criteria which will reflect a baseline level of secure practices, for software that is developed and sold to the U.S. federal government. Software developers will be required to provide visibility into their software and make security data publicly available. Due to this Executive Order, federal agencies may require us to modify our cybersecurity practices and policies, thereby increasing our compliance costs. If we are unable to meet the requirements of the Executive Order, our ability to work with the U.S. government may be impaired and may result in a loss of revenue.
If we do not comply with any current or future rules or regulations that apply to our business, we could be subject to substantial fines and penalties, and we may have to restructure our offerings, exit certain markets or raise the price of our products. In addition, any uncertainty regarding whether particular regulations apply to our business, and how they apply, could increase our costs or limit our ability to grow.
As we continue to expand internationally, we have become subject to telecommunications laws and regulations in the foreign countries where we offer our products. Internationally, we currently offer our products in more than 180 countries and territories.
Our international operations are subject to country-specific governmental regulation and related actions that have increased and will continue to increase our compliance costs or impact our products and platform or prevent us from offering or providing our products in certain countries. Moreover, the regulation of CPaaS companies like us is continuing to evolve internationally and many existing regulations may not fully contemplate the CPaaS business model or how they fit into the communications regulatory framework. As a result, interpretation and enforcement of regulations often involve significant uncertainties. In many countries, including those in the European Union, a number of our products or services are subject to licensing and communications regulatory requirements which increases the level of scrutiny and enforcement by regulators. Future legislative, regulatory or judicial actions impacting CPaaS services could also increase the cost and complexity of compliance and expose us to liability. For example, in some countries, some or all of the services we offer are not considered regulated telecommunications services, while in other countries they are subject to telecommunications regulations, including but not limited to payment into universal service funds, licensing fees, provision of emergency services, provision of information to support emergency services and number portability. Failure to comply with these regulations could result in our Company being issued remedial directions to undertake independent audits and implement effective systems, processes and practices to ensure compliance, significant fines or being prohibited from providing telecommunications services in a jurisdiction.
In addition, from time to time we implement Know-Your-Customer and/or Know-Your-Traffic related processes in the jurisdictions in which we operate, which may create friction for our customers, require management attention, and increase our compliance costs.
32



Moreover, certain of our products may be used by customers located in countries where voice and other forms of Internet Protocol (“IP”) communications may be illegal or require special licensing or in countries on a U.S. embargo list. Even where our products are reportedly illegal or become illegal or where users are located in an embargoed country, users in those countries may be able to continue to use our products in those countries notwithstanding the illegality or embargo. We may be subject to penalties or governmental action if consumers continue to use our products in countries where it is illegal to do so or if we use a local partner to provide services in a country and the local partner does not comply with applicable governmental regulations. Any such penalties or governmental action may be costly and may harm our business and damage our brand and reputation. We may be required to incur additional expenses to meet applicable international regulatory requirements or be required to raise the prices of services, or restructure or discontinue those services if required by law or if we cannot or will not meet those requirements. Any of the foregoing could adversely affect our business, results of operations and financial condition.
If we are unable to obtain or retain geographical, mobile, regional, local or toll-free numbers, or to effectively process requests to port such numbers in a timely manner due to industry regulations, our business and results of operations may be adversely affected.
Our future success depends in part on our ability to obtain allocations of geographical, mobile, regional, local and toll-free direct inward dialing numbers or phone numbers as well as short codes and alphanumeric sender IDs (collectively, “Numbering Resources”) in the United States and foreign countries at a reasonable cost and without overly burdensome restrictions. Our ability to obtain allocations of, assign and retain Numbering Resources depends on factors outside of our control, such as applicable regulations, the practices of authorities that administer national numbering plans or of network service providers from whom we can provision Numbering Resources, such as offering these Numbering Resources with conditional minimum volume call level requirements, the cost of these Numbering Resources and the level of overall competitive demand for new Numbering Resources.
In addition, in order to obtain allocations of, assign and retain Numbering Resources in the EU or certain other regions, we are often required to be licensed by local telecommunications regulatory authorities, some of which have been increasingly monitoring and regulating the categories of Numbering Resources that are eligible for provisioning to our customers. We have obtained licenses and are in the process of obtaining licenses in various countries in which we do business, but in some countries, the regulatory regime around provisioning of Numbering Resources is unclear, subject to change over time, and sometimes may conflict from jurisdiction to jurisdiction. Furthermore, these regulations and governments’ approach to their enforcement, as well as our products and services, are still evolving and we may be unable to maintain compliance with applicable regulations, or enforce compliance by our customers, on a timely basis or without significant cost. Also, compliance with these types of regulation may require changes in products or business practices that result in reduced revenue. Due to our or our customers’ assignment and/or use of Numbering Resources in certain countries in a manner that violates applicable rules and regulations, we have been subjected to government inquiries and audits, and may in the future be subject to significant penalties or further governmental action, and in extreme cases, may be precluded from doing business in that particular country. We have also been forced to reclaim Numbering Resources from our customers as a result of certain events of non-compliance. These reclamations result in loss of customers, loss of revenue, reputational harm, erosion of customer trust, and may also result in breach of contract claims, all of which could have an adverse effect on our business, results of operations and financial condition.
Due to their limited availability, there are certain popular area code prefixes that we generally cannot obtain. Our inability to acquire or retain Numbering Resources for our operations may make our voice and messaging products less attractive to potential customers in the affected local geographic areas. In addition, future growth in our customer base, together with growth in the customer bases of other providers of cloud communications, has increased, which increases our dependence on needing sufficiently large quantities of Numbering Resources. It may become increasingly difficult to source larger quantities of Numbering Resources as we scale and we may need to pay higher costs for Numbering Resources, and Numbering Resources may become subject to more stringent regulation or conditions of usage such as the registration and on-going compliance requirements discussed above.
Additionally, in some geographies, we support number portability, which allows our customers to transfer their existing phone numbers to us and thereby retain their existing phone numbers when subscribing to our voice and messaging products. Transferring existing numbers is a manual process that can take up to 15 business days or longer to complete. Any delay that we experience in transferring these numbers typically results from the fact that we depend on network service providers to transfer these numbers, a process that we do not control, and these network service providers may refuse or substantially delay the transfer of these numbers to us. Number portability is considered an important feature by many potential customers, and if we fail to reduce any related delays, then we may experience increased difficulty in acquiring new customers.

United States federal and state legislation and international laws impose certain obligations on the senders of commercial emails, which could minimize the effectiveness of our platform, and establish financial penalties for non-compliance, which could increase the costs of our business.
The Federal Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 (the “CAN-SPAM Act”) establishes certain requirements for commercial email messages and transactional email messages and specifies penalties for the transmission of email messages that are intended to deceive the recipient as to source or content. Among other things, the CAN-SPAM Act, obligates the sender of commercial emails to provide recipients with the ability to “opt-out” of receiving future commercial emails from the sender. In addition, some states have passed laws regulating commercial email practices that are significantly more restrictive and difficult to comply with than the CAN-SPAM Act. For example, Utah and Michigan prohibit the sending of email messages that advertise products or services that minors are prohibited by law from purchasing or that contain content harmful to minors to email addresses listed on specified child protection registries. Some portions of these state laws may not be preempted by the CAN-SPAM Act. In addition, certain non-U.S. jurisdictions in which we operate have enacted laws regulating the sending of email that are more restrictive than U.S. laws. For example, some foreign laws prohibit sending broad categories of email unless the recipient has provided the sender advance consent (or “opted-in”) to receipt of such email. If we were found to be in violation of the CAN-SPAM Act, applicable state laws governing email not preempted by the CAN-SPAM Act or foreign laws regulating the distribution of email, whether as a result of violations by our customers or our own acts or omissions, we could be required to pay large penalties, which would adversely affect our financial condition, significantly harm our business, injure our reputation and erode customer trust. The terms of any injunctions, judgments, consent decrees or settlement agreements entered into in connection with enforcement actions or investigations against our company in connection with any of the foregoing laws may also require us to change one or more aspects of the way we operate our business, which could impair our ability to attract and retain customers or could increase our operating costs.
Our customers’ and other users’ violation of our policies or other misuse of our platform to transmit unauthorized, offensive or illegal messages, spam, phishing scams, and website links to harmful applications or for other fraudulent or illegal activity could damage our reputation, and we may face a risk of litigation and liability for illegal activities on our platform and unauthorized, inaccurate, or fraudulent information distributed via our platform.
The actual or perceived improper sending of text messages or voice calls may subject us to potential risks, including liabilities or claims relating to consumer protection laws and regulatory enforcement, including fines. For example, the Telephone Consumer Protection Act of 1991 (“TCPA”) restricts telemarketing and the use of automatic SMS text messages without explicit customer consent. TCPA violations can result in significant financial penalties, as businesses can incur penalties or criminal fines imposed by the FCC or be fined up to $1,500 per violation through private litigation or state attorneys general or other state actor enforcement. Class action suits are the most common method for private enforcement. This has resulted in civil claims against our company and requests for information through third-party subpoenas. The scope and interpretation of the laws that are or may be applicable to the delivery of text messages or voice calls are continuously evolving and developing. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face direct liability.
Moreover, certain customers may use our platform to transmit unauthorized, offensive or illegal messages, calls, spam, phishing scams, and website links to harmful applications, reproduce and distribute copyrighted material or the trademarks of others without permission, and report inaccurate or fraudulent data or information. These issues also arise with respect to a portion of those users who use our platform on a free trial basis or upon initial use. These actions are in violation of our policies, in particular, our Acceptable Use Policy. For example, on January 25, 2023, we received a cease-and-desist letter from the FCC alleging that we were transmitting illegal robocall traffic that originated from an independent software vendor customer and their end user customer. In response, we suspended the customers’ accounts and sent the FCC a follow-up letter on February 10, 2023 detailing our fraud mitigation practices and various planned improvements to reduce future risks. There has been no further communication from the agency on this matter. Failure to respond appropriately to the FCC’s allegations could allow domestic carriers to begin blocking all voice traffic transmitting from our network. However, our efforts to defeat spamming attacks, illegal robocalls and other fraudulent activity will not prevent all such attacks and activity. Such use of our platform could damage our reputation and we could face claims for damages, regulatory enforcement, copyright or trademark infringement, defamation, negligence, or fraud. Furthermore, enacting more stringent controls on our customers’ use of our platform to combat such violations of our Acceptable Use Policy could increase friction for our legitimate customers and decrease their use of our platform.
Our customers’ and other users’ promotion of their products and services through our platform might not comply with federal, state, and foreign laws or of contractual requirements imposed by carriers, such as the CTIA Shortcode Agreement, The Campaign Registry, and associated policies. We rely on contractual representations made to us by our customers that their use
34



of our platform will comply with our policies and applicable law, including, without limitation, our email and messaging policies. Although we retain the right to verify that customers and other users are abiding by certain contractual terms, our Acceptable Use Policy and our email and messaging policies and, in certain circumstances, to review their email, messages and distribution lists, our customers and other users are ultimately responsible for compliance with our policies, and we do not systematically audit our customers or other users to confirm compliance with our policies. We cannot predict whether our role in facilitating our customers’ or other users’ activities will result in violations of carrier policies which could result in fines, administrative delays, or service interruptions. We also cannot predict whether our role in facilitating our customers’ or other users’ activities would expose us to liability under applicable state or federal law, or whether that possibility could become more likely if changes to current laws regulating content moderation, such as Section 230 of the Communications Decency Act, are enacted. If we are found liable for our customers’ or other users’ activities, we could be required to pay fines or penalties, redesign business methods or otherwise expend resources to remedy any damages caused by such actions and to avoid future liability.
Additionally, our products may be subject to fraudulent usage, including but not limited to revenue share fraud, domestic traffic pumping, subscription fraud, premium text message scams and other fraudulent schemes. Although our customers are required to set passwords or personal identification numbers to protect their accounts, third parties have in the past been, and may in the future be, able to access and use their accounts through fraudulent means. Furthermore, spammers attempt to use our products to send targeted and untargeted spam messages. We cannot be certain that our efforts to defeat spamming attacks will be successful in eliminating all spam messages from being sent using our platform. In addition, a cybersecurity breach of our customers’ systems could result in exposure of their authentication credentials, unauthorized access to their accounts or fraudulent calls on their accounts, any of which could adversely affect our business, results of operations and financial condition.
Changes in laws and regulations related to the Internet or changes in the Internet infrastructure itself may diminish the demand for our products, and could adversely affect our business, results of operations and financial condition.
The future success of our business depends upon the continued use of the Internet as a primary medium for commerce, communications and business applications. Federal, state or foreign government bodies or agencies have in the past adopted, and may in the future adopt, laws or regulations affecting the use of the Internet as a commercial medium. Changes in these laws or regulations could require us to modify our products and platform in order to comply with these changes. In addition, government agencies or private organizations have imposed and may impose additional taxes, fees or other charges for accessing the Internet or commerce conducted via the Internet. These laws or charges could limit the growth of Internet-related commerce or communications generally or result in reductions in the demand for Internet-based products and services such as our products and platform.
The current legislative and regulatory landscape regarding the regulation of the Internet is subject to uncertainty. For example, in January 2018, the FCC released an order that repealed the “open Internet rules,” often known as “net neutrality,” which could affect the services used by us and our customers. In response to this decision California and a number of states implemented their own net neutrality rules which mirrored parts of the repealed federal regulations. In October 2023, the FCC voted to begin the process of reinstating substantially all of the net neutrality rules that had been in place prior to the 2018 repeal. We cannot predict the actions the FCC may take, whether any new FCC order or state initiatives regulating providers will be modified, overturned, or vacated by legal action, federal legislation, or the FCC itself, or the degree to which further regulatory action – or inaction – may adversely affect our business. Should the FCC not reinstate net neutrality or if state initiatives codifying similar protections are modified, overturned, or vacated, internet service providers may be able to limit our users’ ability to access our platform or make our platform a less attractive alternative to our competitors’ applications. On the other hand, if limits are imposed on the types of traffic that U.S. domestic carriers can carry over their broadband networks, it could adversely affect the amount of carrier-originated traffic that we carry. In a related regulatory context, while the EU requires equal access to internet content, under its Digital Single Market initiative the EU may impose additional requirements that could increase our costs. If new FCC, EU, or other rules directly or inadvertently impose costs on online providers like our business, our expenses may rise. Were any of these outcomes to occur, our ability to retain existing users or attract new users may be impaired, our costs may increase, and our business may be significantly harmed.
In addition, the use of the Internet as a business tool could be adversely affected due to delays in the development or adoption of new standards and protocols to handle increased demands of Internet activity, security, reliability, cost, ease-of-use, accessibility and quality of service. The performance of the Internet and its acceptance as a business tool has been adversely affected by “viruses,” “worms,” and similar malicious programs. If the use of the Internet is reduced as a result of these or other issues, then demand for our products could decline, which could adversely affect our business, results of operations and financial condition.

Our global operations subject us to potential liability under export control, economic trade sanctions, anti-corruption, and other laws and regulations, and such violations could impair our ability to compete in international markets and could subject us to liability for compliance violations.
Certain of our products and services may be subject to export control and economic sanctions laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control as well as similar laws and regulations in other countries in which we do business. Exports of our products and the provision of our services must be made in compliance with these requirements. We take precautions to prevent our products and services from being provided in violation of such laws; however, we are aware of exports of certain of our products to a small number of persons and organizations that are the subject of U.S. sanctions or are located in countries or regions subject to U.S. sanctions. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including: the possible loss of export privileges; fines, which may be imposed on us and responsible employees or managers; and, in extreme cases, the incarceration of responsible employees or managers. Any change in trade protection laws, policies, export, sanctions and other regulatory requirements affecting trade and investments, shift in the enforcement or scope of existing regulations, or change in the countries, governments, persons or technologies targeted by such regulations, could also result in decreased use of our products and services, or in our decreased ability to export our products or provide our services to existing or prospective customers with international operations. Any decreased use of our products and services or limitations on our ability to export our products and provide our services could adversely affect our business, results of operations and financial condition.
Further, we incorporate encryption technology into certain of our products. Various countries regulate the import of certain encryption technology, including through import permitting and licensing requirements, and have enacted laws that could limit our customers’ ability to import our products into those countries. Encryption products and the underlying technology may also be subject to export control restrictions. Governmental regulation of encryption technology and regulation of exports of encryption products, or our failure to obtain required approval for our products, when applicable, could harm our international sales and adversely affect our revenue. Compliance with applicable regulatory requirements regarding the export of our products and provision of our services, including with respect to new releases of our products and services, may create delays in the introduction of our products and services in international markets, prevent our customers with international operations from deploying our products and using our services throughout their globally-distributed systems or, in some cases, prevent the export of our products or provision of our services to some countries altogether.
We are also subject to U.S. and foreign anti-corruption and anti-bribery laws, including the FCPA, the UK Bribery Act 2010, and other anti-corruption laws and regulations in the countries in which we conduct activities. Anti-corruption laws are interpreted broadly and generally prohibit companies, their employees, agents, representatives, business partners, and third-party intermediaries from directly or indirectly authorizing, offering, or providing, improper payments or things of value to recipients in the public or private sector, and also require that we maintain accurate books and records and adequate internal controls and compliance procedures designed to prevent violations. We sometimes leverage third parties to sell our products and conduct our business abroad. We, our employees, agents, representatives, business partners and third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and we may be held liable for the corrupt or other illegal activities of these employees, agents, representatives, business partners or third-party intermediaries even if we do not explicitly authorize such activities. It is possible that our employees, agents, representatives, business partners or third-party intermediaries could fail to comply with our policies and applicable laws and regulations, for which we may ultimately be held responsible. Any allegations or violation of the FCPA or other applicable anti-bribery and anti-corruption laws and anti-money laundering laws could result could result in whistleblower complaints, sanctions, settlements, prosecution, enforcement actions, significant fines and penalties, damages, adverse media coverage, investigations, loss of export privileges, severe criminal or civil sanctions, or suspension or debarment from government contracts, all of which may have an adverse effect on our reputation, business, results of operations, and prospects. Responding to any investigation or action would likely result in a materially significant diversion of management’s attention and resources, significant defense costs and other professional fees.
The standards imposed by private entities and inbox service providers to regulate the use and delivery of email have in the past interfered with, and may continue to interfere with, the effectiveness of our platform and our ability to conduct business.
From time to time, private entities and inbox service providers impose requirements that impact our and our customers’ ability to use and deliver email. For example, some of our IP addresses have become, and we expect will continue to be, listed with one or more denylisting entities due to the messaging practices of our customers and other users. We may be at an increased risk of having our IP addresses denylisted due to our scale and volume of email processed, compared to our smaller
36



competitors. There can be no guarantee that we will be able to successfully remove ourselves from those lists. Because we fulfill email delivery on behalf of our customers, denylisting of this type could undermine the effectiveness of our customers’ transactional email, email marketing programs and other email communications, all of which could have a material negative impact on our business, financial condition and results of operations. In the first quarter of 2024, Google and Yahoo began enforcing new email sender requirements aimed at sender authentication, including Domain-based Message Authentication, Reporting and Conformance (“DMARC”) record requirements. We expect that these requirements will require us to devote time and resources toward compliance efforts, and these or similar authentication requirements imposed in the future could result in reduced volumes for our email products and could adversely affect our business, financial condition and results of operations.
Additionally, inbox service providers can block emails from reaching their users or categorize certain emails as “promotional” emails and, as a result, direct them to an alternate or “tabbed” section of the recipient’s inbox. The implementation of new or more restrictive policies by inbox service providers may make it more difficult to deliver our customers’ emails, particularly if we are not given adequate notice of a change in controlpolicy or struggle to update our platform or services to comply with the changed policy in a reasonable amount of time. If the open rates of our Companycustomers’ emails are negatively impacted by the actions of inbox service providers to block or categorize emails then customers may question the effectiveness of our platform and cancel their accounts. This, in turn, could harm our business, financial condition and results of operations.
Any legal proceedings or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome.
We are and may in the future become subject to legal proceedings and claims that arise in the ordinary course of business, such as disputes or employment claims made by our current or former employees. Any litigation, whether meritorious or not, could harm our reputation, will increase our costs and may divert management’s attention, time and resources, which may in turn seriously harm our business. Insurance might not cover such claims or the costs to defend such claims, might not provide sufficient payments to cover all the costs to resolve one or more such claims, and might not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipated costs and could seriously harm our business. If we are required to make substantial payments or implement significant changes to our operations as a result of legal proceedings or claims, our business, results of operations and financial condition could be adversely affected.
Risks Related to Financial and Accounting Matters
We face exposure to foreign currency exchange rate fluctuations, and such fluctuations could adversely affect our business, results of operations and financial condition.
As our international operations expand, our exposure to the effects of fluctuations in currency exchange rates grows. For example, global geopolitical events, such as the war in Ukraine and conflict in the Middle East, economic events, public health epidemics and pandemics such as the COVID-19 pandemic, trade tariff developments and other events have nocaused global economic uncertainty and variability in foreign currency exchange rates. While we have primarily transacted with customers and business partners in U.S. dollars, we have also conducted business in currencies other than the U.S. dollar. We expect to expand the number of transactions with customers that are denominated in foreign currencies in the future as we continue to expand our business internationally. We also incur expenses for some of our network service provider costs outside of the United States in local currencies and for employee compensation and other operating expenses at our non-U.S. locations in the respective local currency. Fluctuations in the exchange rates between the U.S. dollar and other currencies could result in an increase to the U.S. dollar equivalent of such obligationsexpenses.
In addition, our international subsidiaries maintain net assets that are denominated in placecurrencies other than the functional operating currencies of these entities. As we continue to expand our international operations, we become more exposed to the effects of fluctuations in currency exchange rates. Accordingly, changes in the value of foreign currencies relative to the U.S. dollar can affect our results of operations due to transactional and translational remeasurements. As a result of such foreign currency exchange rate fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors and securities analysts who follow our stock, the trading price of our common stock could be adversely affected.
We have implemented a program to hedge transactional exposure against the Euro, and may do so in the future with respect to other foreign currencies. We also use derivative instruments, such as foreign currency forward and option contracts,
37



to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such hedging activities may not offset any or more than a portion of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place. Moreover, the use of hedging instruments may introduce additional risks if we are unable to structure effective hedges with such instruments.
We have incurred substantial indebtedness that may decrease our business flexibility, access to capital, and/or increase our borrowing costs, and we may still incur substantially more debt, which may adversely affect our operations and financial results.
As of December 31, 2023, we had $1.0 billion of indebtedness outstanding (excluding intercompany indebtedness). Our indebtedness may:
limit our ability to obtain additional financing to fund future working capital, capital expenditures, business opportunities, acquisitions or other general corporate requirements;
require a portion of our named executive officers.cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, business opportunities, acquisitions and other general corporate purposes;
increase our vulnerability to adverse changes in general economic, industry and competitive conditions;
For detailed descriptionsexpose us to the risk of increased interest rates as certain of our borrowings, including borrowings under a future revolving credit facility, may be at variable rates of interest;
place us at a competitive disadvantage compared to our less leveraged competitors; and
increase our cost of borrowing.
In addition, the indenture which governs our 3.625% notes due 2029 (the “2029 Notes”) and our 3.875% notes due 2031 (the “2031 Notes,” and together with the 2029 Notes, the “Notes”) contains restrictive covenants that limit our ability to engage in activities that may be in our long-term best interest. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could permit the trustee, or permit the holders of the post-employment compensation arrangements we maintain with our named executive officers, as well as an estimateNotes to cause the trustee, to declare all or part of the potentialNotes to be immediately due and payable or to exercise any remedies provided to the trustee and/or result in the acceleration of substantially all of our indebtedness. Any such event would adversely affect our business, results of operations and financial condition.
If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and may be forced to reduce or delay investments and capital expenditures. We may be forced to sell assets, seek additional capital, or restructure or refinance our indebtedness, including the Notes. Our ability to restructure or refinance our debt will depend on, among other things, the condition of capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments and the indenture that governs the Notes may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and benefits payableprincipal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness and our financial condition. In the absence of such cash flows and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations.
We may require additional capital to support our business, and this capital might not be available on acceptable terms, if at all.
We intend to continue to make investments to support our business and may require additional funds. In particular, we may seek additional funds to develop new products and enhance our platform and existing products, expand our operations, including our sales and marketing organizations and our presence outside of the United States, improve our infrastructure or acquire complementary businesses, technologies, services, products and other assets. In addition, we may use a portion of our cash to satisfy tax withholding and remittance obligations related to outstanding restricted stock units. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing that we may
38



secure in the future could involve restrictive covenants relating to our named executive officerscapital raising activities, our ability to repurchase stock, and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. We may not be able to obtain additional financing on terms favorable to us, if at all, particularly during times of market volatility and general economic instability. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth, scale our infrastructure, develop product enhancements and to respond to business challenges could be significantly impaired, and our business, results of operations and financial condition may be adversely affected.
We rely on assumptions and estimates to calculate certain of our key metrics, and real or perceived inaccuracies in such metrics could adversely affect our reputation and our business.
We rely on assumptions and estimates to calculate certain of our key metrics, such as Active Customer Accounts and Dollar-Based Net Expansion Rate. Our key metrics are not based on any standardized industry methodology and are not necessarily calculated in the same manner or comparable to similarly titled measures presented by other companies. Similarly, our key metrics may differ from estimates published by third parties or from similarly titled metrics of our competitors due to differences in methodology. The numbers that we use to calculate Active Customer Accounts and Dollar-Based Net Expansion Rate are based on internal data. While these numbers are based on what we believe to be reasonable judgments and estimates for the applicable period of measurement, there are inherent challenges in measuring usage. We regularly review and may adjust our processes for calculating our internal metrics to improve their accuracy. If investors or analysts do not perceive our metrics to be accurate representations of our business, or if we discover material inaccuracies in our metrics, our reputation, business, results of operations, and financial condition would be harmed.
If our estimates or judgments relating to our critical accounting policies prove to be incorrect, our results of operations could be adversely affected.
The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under their post-employment compensation arrangements, see “Employment Agreementsthe circumstances, as provided in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The results of these estimates form the basis for making judgments about the carrying values of assets, liabilities and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Assumptions and estimates used in preparing our consolidated financial statements include those related to revenue recognition and business combinations. Our results of operations may be adversely affected if our assumptions change or Offer Letters with Named Executive Officers”if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of securities analysts and “Potential Payments Upon Terminationinvestors, resulting in a decline in the trading price of our common stock.
Changes in accounting standards or Changepractices may cause adverse, unexpected financial reporting fluctuations and affect our results of operations.
A change in Control” below.accounting standards or practices may have a significant effect on our results of operations and may even affect our reporting of transactions completed before the change is effective. New accounting pronouncements and varying interpretations of accounting pronouncements have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business. For example, Accounting Standards Codification (“ASC”) 842, “Leases” that became effective January 1, 2019, had a material impact on our consolidated financial statements as described in detail in Note 2 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020. Adoption of these types of accounting standards and any difficulties in implementation of changes in accounting principles, including the ability to modify our accounting systems, could cause us to fail to meet our financial reporting obligations, which result in regulatory discipline and harm investors' confidence in us.
If our goodwill or intangible assets become impaired, we may be required to record a significant charge to earnings.
We review our intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. As of December 31, 2023, we carried a net $5.6 billion of goodwill and intangible assets. An adverse change in market conditions or significant changes in accounting conclusions, particularly if such changes have the effect of changing one of our critical assumptions or estimates, could result in a change to the estimation of fair value that could result in an impairment charge to our goodwill or intangible assets. For example, during the year ended December 31, 2023, we recorded an impairment of intangible assets related to Segment totaling
39
Other Compensation Policies


approximately $285.7 million, as described in additional detail in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Any such charges may adversely affect our results of operations.
If we fail to maintain an effective system of disclosure controls and Practices
internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.
Equity Awards Grant Policy
Under our AmendedAs a public company, we are required to maintain internal control over financial reporting and Restated Equity Award Grant Policy,to report any material weaknesses in such internal control. Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) requires that we generally grant equity awards on a regularly scheduled basis to enhanceevaluate and determine the effectiveness of our internal control over financial reporting and provide a management report on internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our equity award grant processfinancial statements will not be prevented or detected on a timely basis.
Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further, weaknesses in our disclosure controls and internal control over financial reporting may be discovered in the future.

Risks Related to Tax Matters
Our ability to use our net operating losses and certain other tax attributes to offset future taxable income and taxes may be subject to certain limitations.
As of one shareDecember 31, 2023 we had U.S. federal, state and foreign net operating loss carryforwards (“NOLs”), of $3.4 billion, $2.6 billion and $1.0 billion, respectively. Utilization of these NOL carryforwards depends on our future taxable income, and there is risk that a portion of our Class A commonexisting NOLs could expire unused, and that even if we achieve profitability, the use of our unexpired NOLs would be subject to limitations, which could materially and adversely affect our operating results. U.S. federal NOLs generated in taxable years beginning before January 1, 2018, may be carried forward only 20 years to offset future taxable income, if any. Under current law, U.S. federal NOLs generated in taxable years beginning after December 31, 2017, can be carried forward indefinitely, but the deductibility of such U.S. federal NOLs in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to federal law.
Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), and corresponding provisions of state law, a corporation that undergoes an “ownership change” (generally defined as a greater than 50-percentage-point cumulative change (by value) in the equity ownership of certain stockholders over a rolling three-year period) is subject to limitations on its ability to utilize its pre-change NOLs and other pre-change tax attributes to offset post-change taxable income and taxes. Our existing NOLs and other tax attributes may be subject to limitations arising from previous ownership changes, and if we undergo an ownership change in the future, our ability to utilize NOLs could be further limited by Section 382 of the Code. Future changes in our stock onownership, some of which may be outside of our control, could result in an ownership change under Section 382 of the effective dateCode. In addition, at the state level, there may be periods during which the use of grant,NOL carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.
We may have additional tax liabilities, which could harm our business, results of operations and financial condition.
Significant judgments and estimates are required in determining our provision for income taxes and other tax liabilities. Our tax expense may be impacted, for example, if tax laws change or are clarified to our detriment or if no closing price is reportedtax authorities successfully challenge the tax positions that we take, such as, for example, positions relating to the arm’s-length pricing standards for our intercompany transactions and our indirect tax positions. In determining the adequacy of our provision for
40



income taxes, we assess the likelihood of adverse outcomes that could result if our tax positions were challenged by the Internal Revenue Service (“IRS”), and other tax authorities. Should the IRS or other tax authorities assess additional taxes as a result of examinations, we may be required to record charges to operations that could adversely affect our results of operations and financial condition.
We conduct operations in many tax jurisdictions throughout the United States and internationally. In many of these jurisdictions, non-income-based taxes, such date, the closing priceas sales, value-added tax, goods and services tax, and telecommunications taxes, are assessed on the last day preceding such date for which a closing price is reported. If the grantour operations or our sales to customers. We are subject to indirect taxes, and may be subject to certain other taxes, in some of restricted stock or of RSUs is denominatedthese jurisdictions. We collect certain telecommunications-based taxes from our customers in dollars,certain jurisdictions, and we expect to continue expanding the number of sharesjurisdictions in which we will collect these taxes in the future.
Many states are also pursuing legislative expansion of restricted stock or RSUsthe scope of goods and services that are granted willsubject to sales and similar taxes as well as the circumstances in which a vendor of goods and services must collect such taxes. Following the United States Supreme Court decision in South Dakota v. Wayfair, Inc., states are now free to levy taxes on sales of goods and services based on an “economic nexus,” regardless of whether the seller has a physical presence in the state. Any additional fees and taxes levied on our services by any state may adversely impact our results of operations.
Historically, we have not billed or collected taxes in certain jurisdictions and, in accordance with GAAP, we have recorded a provision for our tax exposure in these jurisdictions when it is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. We reserved $18.0 million and $22.2 million for domestic jurisdictions and jurisdictions outside of the United States, respectively, on our December 31, 2023 balance sheet for these tax payments. These estimates include several key assumptions, including, but not limited to, the taxability of our products, the jurisdictions in which we believe we have nexus or a permanent establishment, and the sourcing of revenues to those jurisdictions. In the event these jurisdictions challenge our assumptions and analysis, our actual exposure could differ materially from our current estimates and reserves. If the actual payments we make to any jurisdiction exceed the accrual in our balance sheet, our results of operations would be harmed. In addition, some customers may question the incremental tax charges and seek to negotiate lower pricing from us, which could adversely affect our business, results of operations and financial condition.
We are in discussions with certain jurisdictions regarding potential sales and other indirect taxes for prior periods that we may owe. If any of these jurisdictions disagree with management’s assumptions and analysis, the assessment of our tax exposure could differ materially from management’s current estimates. For example, in 2020, San Francisco City and County assessed us for $38.8 million in taxes, including interest and penalties, which exceeded the $11.5 million we had accrued for that assessment. We paid the full amount under protest and filed a lawsuit on May 27, 2021 contesting the assessment. We entered into a settlement agreement in November 2023 pursuant to which San Francisco paid us $18.0 million in settlement of our claims.
Our global operations and structure subject us to potentially adverse tax consequences.
We generally conduct our global operations through subsidiaries and report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. In particular, our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. Also, our tax expense could be calculated by dividingaffected depending on the dollarapplicability of withholding and other taxes (including withholding and indirect taxes on software licenses and related intercompany transactions) under the tax laws of certain jurisdictions in which we have business operations. The relevant revenue and taxing authorities may disagree with positions we have taken generally, or our determinations as to the value of the approved award by the average closing market price on The New York Stock Exchange of one shareassets sold or acquired or income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our Class Aoperations.
Changes in, or interpretations of, tax rules and regulations or our tax positions may materially and adversely affect our income taxes.
We are subject to income taxes in both the United States and numerous international jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Our effective tax rates may fluctuate significantly on a quarterly basis because of a variety of factors, including changes in the mix of earnings and losses in countries with differing statutory tax rates, changes in our business or structure, changes in tax laws that could adversely impact our income or non-income taxes or the expiration of or disputes about certain tax agreements in a particular country. We are subject to audit by various tax authorities. In accordance with U.S. GAAP, we recognize income tax benefits, net of required valuation allowances and accrual for uncertain tax positions. Although we believe our tax estimates are reasonable, the final
41



determination of tax audits and any related litigation could be materially different than that which is reflected in historical income tax provisions and accruals. Should additional taxes be assessed as a result of an audit or litigation, an adverse effect on our results of operations, financial condition and cash flows in the period or periods for which that determination is made could result.
Changes in tax laws or tax rulings, or changes in interpretations of existing laws, could cause us to be subject to additional income-based taxes and non-income taxes (such as payroll, sales, use, value-added, digital tax, net worth, property, and goods and services taxes), which in turn could materially affect our financial position and results of operations. Additionally, new, changed, modified, or newly interpreted or applied tax laws could increase our customers’ and our compliance, operating and other costs, as well as the costs of our products. For example, on August 16, 2022, the Inflation Reduction Act of 2022 was signed into law, with tax provisions primarily focused on implementing a 15% minimum tax on global adjusted financial statement income, effective for tax years beginning after December 31, 2022, and a 1% excise tax on share repurchases occurring after December 31, 2022, which resulted in an excise tax payable calculated on our 2023 share repurchases.
As another example, beginning in 2022, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) eliminates the option to deduct research and development expenditures currently and requires taxpayers to capitalize and amortize them over five or fifteen years pursuant to Section 174 of the Code, which impacts our effective tax rate and our cash tax liability in 2023. If the requirement to capitalize Section 174 expenditures is not modified by legislation, it will continue to impact our effective tax rate and our cash tax liability.

On October 8, 2021, the Organization for Economic Co-operation and Development (the “OECD”) announced the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (the “Framework”) which agreed to a two-pillar solution to address tax challenges arising from digitalization of the economy. On December 20, 2021, the OECD released Pillar Two Model Rules defining the global minimum tax rules, which contemplate a minimum tax rate of 15% for large multinational companies. On December 15, 2022, the European Union (EU) Member States formally adopted the EU’s Pillar Two Directive and various countries have enacted or are in the process of enacting legislation on these rules. These changes, when enacted by various countries in which we do business, may increase our taxes in these countries. Changes to these and other areas in relation to international tax reform, including future actions taken by foreign governments in response to the Tax Act, could increase uncertainty and may adversely affect our tax rate and cash flow in future years.

Stock Ownership Policy
To further align the interests of our executive officers with those of our stockholders and to promote a long-term perspective in managing our Company, in April 2018, we adopted a stock ownership policy for our Chief Executive Officer and executive officers subject to Section 16 of the Exchange Act (“
Section
 16 Officers
”), including each of our named executive officers. We amended and restated this stock ownership policy in September 2020 and in March 2022. In March 2022, we revised the stock ownership policy to, among other things, increase the salary-multiple for our named executive officers (other than our Chief Executive Officer) from one time to three times his or her annual base salary, eliminate
pre-established
share number thresholds, and eliminate vested but unexercised
in-the-money
options from the share ownership calculation.
Our stock ownership policy, as amended, requires each named executive officer to acquire and hold a numbersales of shares of our common stock equalby our stockholders;
our issuance or repurchase of shares of our common stock;
short selling of our common stock or related derivatives;
failure of securities analysts to maintain coverage of us, changes in financial estimates or the publication of reports or statements by securities analysts or investors who follow our company, or our failure to meet these estimates or the expectations of investors;
the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;
42



announcements by us or our competitors of new products or services;
the public’s reaction to our press releases, other public announcements and filings with the SEC;
rumors and market speculation involving us or other companies in our industry;
changes in laws, industry standards, regulations or regulatory enforcement in the United States or internationally;
actual or anticipated changes in our results of operations or fluctuations in our results of operations or actual or anticipated changes in our strategy or the organization of our business;
actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;
litigation involving us, our industry or both, or investigations by regulators into our operations or those of our competitors;
developments or disputes concerning our intellectual property or other proprietary rights;
announced or completed acquisitions of businesses, products, services or technologies by us or our competitors;
changes in accounting standards, policies, guidelines, interpretations or principles;
any significant change in our management, including changes in the pace of hiring; and
general political, social, economic and market conditions, in both domestic and foreign markets, including the effects of the war in Ukraine and conflict in the Middle East on the global economy, changes in the labor market, supply chain disruptions, inflation, increased interest rates, instability and volatility in the banking and financial services sector, and slow or negative growth of our markets.
In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.
Substantial future sales of shares of our common stock could cause the market price of our common stock to decline.
The market price of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers and significant stockholders, or the perception in the market that holders of a large number of shares intend to sell their shares. Additionally, the shares of common stock subject to outstanding options and restricted stock unit awards under our equity incentive plans and the shares reserved for future issuance under our equity incentive plans will become eligible for sale in the public market upon issuance, subject to applicable insider trading policies.
We may not realize the anticipated long-term stockholder value of our share repurchase program, and any failure to repurchase our common stock after we have announced our intention to do so may negatively impact our stock price.
In February 2023, our board of directors authorized the repurchase of up to $1.0 billion of our common stock from time to time through a multipleshare repurchase program. Under our share repurchase program, we may make repurchases of stock through a variety of methods, including open share market purchases, privately negotiated purchases, entering into one or more confirmations or other contractual arrangements with a financial institution counterparty to effectuate one or more accelerated stock repurchase contracts, forward purchase contracts or similar derivative instruments, Dutch auction tender offers, or through a combination of any of the foregoing, in accordance with applicable federal securities laws. Our share repurchase program terminates at 11:59 pm Pacific Time on December 31, 2024, does not obligate us to repurchase any specific number of shares, and may be suspended at any time at our discretion and without prior notice. The timing and amount of any repurchases, if any, will be subject to liquidity, stock price, market and economic conditions, compliance with applicable legal requirements such named executive officer’s annual base salary until he or she ceasesas Delaware surplus and solvency tests and other relevant factors. Any failure to repurchase stock after we have announced our intention to do so may negatively impact our reputation and investor confidence in us and may negatively impact our stock price.

The existence of our share repurchase program could cause our stock price to be our Chief Executive Officer or a Section 16 Officer, as applicable. The multiplehigher than it otherwise would be and could potentially reduce the market liquidity for our Chief Executive Officerstock. Although our share repurchase program is six times his annual base salaryintended to enhance long-term stockholder value, there is no assurance that it will do so because the market price of our common stock may decline below the levels at which we repurchase shares, and short-term stock price fluctuations could reduce the multipleeffectiveness of the program.
Repurchasing our common stock reduces the amount of cash we have available to fund working capital, capital expenditures, strategic acquisitions or business opportunities, and other general corporate purposes, and we may fail to realize the anticipated long-term stockholder value of any share repurchase program.
If securities or industry analysts change their recommendations regarding our common stock adversely, the trading price of our common stock and trading volume could decline.
The trading market for our other named executive officerscommon stock is three times hisinfluenced by the research and reports that securities or her annual base salary. For purposesindustry analysts may publish about us, our business, our market or our competitors. If any of the analysts who cover us change their recommendation regarding our common stock adversely, or provide more favorable relative recommendations about our competitors, the trading price of our common stock ownership policy, we only count directly and beneficially owned shares, including shares purchased through our 2016 Employee Stock Purchase Plan (as amended and restated, the “
ESPP
”) or Section 401(k) Plan, if applicable, and shares underlying vested RSUs that are held or deferred. Each named executive officer has five years from the later of his or her designation as our Chief Executive Officer or Section 16 Officer, as applicable, or from the original effective date of the policywould likely decline. If any analyst who covers us were to obtain the required ownership level.
Compensation Recovery Policy

Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as provisions of Delaware law, could impair a takeover attempt.
Our certificate of incorporation, bylaws and Delaware law contain provisions which could have the best interestseffect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our board of directors. Among other things, our certificate of incorporation and bylaws include provisions:
authorizing “blank check” preferred stock, which could be issued by our board of directors without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;
limiting the liability of, and providing indemnification to, our directors and officers;
limiting the ability of our stockholders to call and bring business before special meetings;
providing that our board of directors is classified into three classes of directors with staggered three-year terms;
prohibiting stockholder action by written consent, instead requiring all stockholder actions to be taken at a meeting of our stockholders;
requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our board of directors;
controlling the procedures for the conduct and scheduling of board of directors and stockholder meetings; and
providing for advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted upon at a meeting of stockholders, which may include providing for compensation that isdiscourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.
These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.
As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation Law, which prevents certain stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of at least two-thirds of our outstanding common stock not deductibleheld by us due to the deduction limit under Section 162(m).such 15% or greater stockholder.

Section 409A of the Internal Revenue Code
Section 409A of the Code imposes additional significant taxes in the event that an executive officer, director or service provider receives “deferred compensation” that does not satisfy the requirements of Section 409A of the Code. Although we do not maintain a traditional nonqualified deferred compensation planopportunity for our executive officers, Section 409A of the Code does applystockholders to certain severance arrangements, bonus arrangements and equity awards, and we have structured all such arrangements and awards inreceive a manner to either avoid or comply with the applicable requirements of Section 409A of the Code. For our

Accountingpremium for Stock-Based Compensation
We follow the Financial Accounting Standard Board’s Accounting Standards Codification Topic 718 (“
FASB ASC Topic 718
”) for our stock-based compensation awards. FASB ASC Topic 718 requires us to measure the compensation expense for all share-based payment awards made to our employees and
non-employee
members of our board of directors, including options to purchasetheir shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.
Our bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
Our bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:
any derivative action or proceeding brought on our behalf;
any action asserting a breach of fiduciary duty owed by our directors, officers, employees or our stockholders;
any action asserting a claim against us arising under the Delaware General Corporation Law; and
any action asserting a claim against us that is governed by the internal-affairs doctrine (the “Delaware Forum Provision”).
The Delaware Forum Provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim under the Securities Act, for which the United States District Court for the Northern District of California has sole and exclusive jurisdiction (the “Federal Forum Provision”), as we are based in the State of California. In addition, our bylaws provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to the Delaware Forum Provision and the Federal Forum Provision; provided, however, that stockholders cannot and will not be deemed to have waived our compliance with the U.S. federal securities laws and the rules and regulations thereunder.
The Delaware Forum Provision and the Federal Forum Provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or employees, which may discourage lawsuits against us and our directors, officers and employees. If a court were to find the Delaware Forum Provision and the Federal Forum Provision in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.
We do not expect to declare any dividends in the foreseeable future.
We have never paid dividends and we do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. Consequently, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase our common stock.
General Risks
Our business is subject to the risks of pandemics, earthquakes, fire, floods and other natural catastrophic events, and to interruption by man-made problems such as power disruptions, computer viruses, data security breaches, terrorism or war.
Our business operations are subject to interruption by natural disasters, flooding, fire, power shortages, public health epidemics or pandemics, terrorism, political unrest, cyber-attacks, geopolitical instability, war, the effects of climate change and other events beyond our control. For example, our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity. A significant natural disaster, such as an earthquake, fire or flood, occurring at our headquarters, at one of our other facilities or where a business partner is located could adversely affect our business, results of operations and financial condition. Further, if a natural disaster or man-made problem were to affect our service providers, this could adversely affect the ability of our customers to use our products and platform. Natural disasters, public health epidemics or pandemics, such as the COVID-19 pandemic, and geopolitical events, such as the war in Ukraine and conflict in the Middle East, could cause disruptions in our or our customers’ businesses, national economies or the world economy as a whole.
We also rely on our network and third-party infrastructure and enterprise applications and internal technology systems for our engineering, sales and marketing, and operations activities. Although we maintain incident management and disaster
45



response plans, in the event of a major disruption caused by a natural disaster or man-made problem, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in our development activities, lengthy interruptions in service, breaches of data security and loss of critical data, any of which could adversely affect our business, results of operations and financial condition.
In addition, computer malware, viruses and computer hacking, fraudulent use attempts and phishing attacks have become more prevalent in our industry, have occurred on our platform in the past and may occur on our platform in the future. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, any failure to maintain performance, reliability, security, integrity and availability of our products and technical infrastructure to the satisfaction of our customers may harm our reputation and our ability to retain existing customers and attract new customers. In addition, global climate change could result in certain types of natural disasters occurring more frequently or with more intense effects. Any such events may result in users being subject to service disruptions or outages, and we may not be able to recover our technical infrastructure in a timely manner to maintain or resume operations, which may adversely affect our financial results.
Our reputation and/or business could be negatively impacted by ESG matters and/or our reporting of such matters.
There is an increasing focus from regulators, certain investors, and other stakeholders concerning ESG matters, both in the United States and internationally. We communicate certain ESG-related initiatives, goals, and/or commitments regarding environmental matters, diversity, responsible sourcing and social investments, and other matters in our annual Impact and DEI Report, on our website, in our filings with the SEC, and elsewhere. These initiatives, goals, or commitments could be difficult to achieve and costly to implement. We could fail to achieve, or be perceived to fail to achieve, our ESG-related initiatives, goals, or commitments. In addition, we could be criticized for the timing, scope or nature of these initiatives, goals, or commitments, or for any revisions to them. To the extent that our required and voluntary disclosures about ESG matters increase, we could be criticized for the accuracy, adequacy, or completeness of such disclosures. Our actual or perceived failure to achieve our ESG-related initiatives, goals, or commitments could negatively impact our reputation, result in ESG-focused investors not purchasing and holding our stock, or otherwise materially harm our business.

As discussed in more detail under the heading “Governance” below, our board of directors’ oversight of cybersecurity risk is supported by our audit committee, which regularly interacts with our ERM function, our Chief Digital Officer (“CDO”), our Chief Information Security Officer (“CISO”), other members of management, and relevant committees and working groups, including management’s Enterprise Risk Committee (“ERC”), Cyber Incident Task Force (“CITF”), and Security Incident Response Team (“SIRT”), in its oversight of cybersecurity-related risk.
Risk Assessment.We devote significant resources and designate high-level personnel, including our ERC, which includes our Chief Legal Officer (“CLO”), our CDO, our CISO, our Vice President of Internal Audit, and our Vice President of Ethics, Compliance and Risk Management, to manage the cybersecurity risk assessment and mitigation process. We conduct
46



security assessments both internally and with the assistance of third parties to identify cybersecurity threats periodically and to identify any potentially material changes in our business practices that may affect information systems that are vulnerable to such cybersecurity threats. These security assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential impact of such risks, and the sufficiency and effectiveness of existing policies, procedures, systems, and controls to manage such risks. Risk themes identified during our risk assessments guide annual cybersecurity planning activities and investments to improve security coverage, technology capabilities and processes.
Technical Safeguards. We deploy, maintain, and regularly monitor the effectiveness of technical safeguards that are designed to protect our information systems from cybersecurity threats. We align our security program to recognized frameworks and industry standards. We make investments in core security capabilities, including awareness and training, identity and access, incident response, product security, cloud security, enterprise security, risk management, and supply chain risk, in order to enable us to better identify, protect, detect, respond to, and recover from evolving security threats. Our technical safeguards include firewalls, intrusion prevention and detection systems, anti-malware functionality and access controls, which are evaluated and improved through internal and external security assessments and cybersecurity threat intelligence. We regularly assess our safeguards through internal testing by our assurance teams. We also leverage external third-party testing (e.g., penetration testing, attack surface mapping, and security maturity assessments) and seek third-party certifications (e.g., SOC2, ISO, and PCI DSS). Following our risk assessments, we evaluate whether and/or how to re-design and/or enhance our safeguards to reasonably address any identified risks or gaps.
Incident Response and Recovery Planning. We have established comprehensive incident response and recovery plans that address the full lifecycle of our response to a cybersecurity incident. These plans are periodically tested and evaluated.
Third-Party Risk Management. We maintain a comprehensive, risk-based approach to identifying and overseeing cybersecurity risks presented by third parties, including vendors, service providers and other external users of our systems, as well as the systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems. We perform due diligence on vendors, service providers and other third-party users of our systems at initial onboarding and periodically thereafter. We require that third-party service providers have the ability to implement and maintain reasonable and appropriate security measures, consistent with applicable laws, in connection with their work with us, and to promptly report any actual or suspected breach of their security measures that may affect our company.
Security Awareness and Training. Our security awareness program requires that employees and certain contractors complete comprehensive security training upon joining the company and annually thereafter. The training covers critical security topics to ensure our workforce stays informed about top-of-mind security areas, such as phishing. The training helps ensure that our personnel have the knowledge and skills required to protect our digital assets and critical data. In addition, we conduct awareness campaigns on cybersecurity threats as a means to equip our personnel with effective tools to address such threats and to communicate our evolving information security policies, standards, processes and practices.
We engage in the periodic assessment and testing of our cybersecurity policies, standards, processes and practices, including through audits, assessments, tabletop exercises, threat modeling, vulnerability testing and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. To assist with such assessment and testing, we engage assessors, consultants, auditors, and other third parties to perform assessments on our cybersecurity measures, including for third-party testing and certifications (as described above under “Technical Safeguards”), information security maturity assessments, customer audits, and independent reviews of our information security control environment and operating effectiveness. The material results of such assessments, audits and reviews are reported to our audit committee, and we adjust our cybersecurity policies, standards, processes and practices as necessary based on the information provided.
To date, cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected our company, including our business strategy, results of operations, or financial condition. For additional information regarding whether any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, are reasonably likely to materially affect our company in the future, including our business strategy, results of operations, or financial condition, see Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.
Governance
Our board of directors, in coordination with our audit committee, oversees our ERM process, including the management of cybersecurity risks, and is responsible for monitoring and assessing strategic risk exposure. Our management team and its committees, including our ERC, our CITF, our SIRT, and our core information security operational teams, in partnership with our engineering teams, are responsible for the day-to-day management and mitigation of the material cybersecurity risks we face.
47



Our board of directors administers its cybersecurity risk oversight function through our audit committee. Our audit committee receives regular presentations and reports on cybersecurity risks, which address a wide range of topics including recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the threat environment, technological trends and information security considerations arising with respect to our peers and third parties, and risks relating to cybersecurity incidents. Our board of directors receives quarterly updates from our audit committee on ERM and cybersecurity risks.
Our ERC, comprised of our CLO, our CDO, our CISO, our Vice President of Internal Audit, and our Vice President of Ethics, Compliance and Risk Management, among others, oversees our ERM activities, including cybersecurity-related risks. Our CDO and our CISO (who reports to our CDO) are primarily responsible for the assessment and management of our material risks from cybersecurity threats, working collaboratively and cross-functionally to design and implement our cybersecurity policies and processes, including those described in “Risk Management and Strategy” above, and for responding to any cybersecurity incidents. In addition, our CITF (which includes our CDO, our CISO, our CLO, and our Chief Financial Officer (“CFO”)) is primarily responsible for evaluating cybersecurity incidents, gathering and assessing facts relevant to applicable regulatory reporting and disclosure obligations, making recommendations to our Chief Executive Officer and CFO regarding such disclosure, and advising our board of directors and audit committee on the effectiveness of policies and procedures related to the disclosure of cybersecurity incidents.
To facilitate our cybersecurity risk management program, multidisciplinary teams throughout our company are deployed to address cybersecurity threats and to respond to cybersecurity incidents. Through ongoing communications with these teams, our CDO, our CISO, and the SIRT monitor the detection, mitigation and remediation of cybersecurity threats and incidents in real time, and report such threats and incidents to the CITF when appropriate.
Our CDO has over 25 years of experience at technology companies and has been in the security space for over 18 years, including serving as chief security officer at a public company and leading security engineering at another public company. Our CDO also serves on the board of directors of a publicly traded cybersecurity company. Our CDO holds an undergraduate degree in electronics engineering and a graduate degree in business administration and management. Our CISO has over 18 years of experience managing cybersecurity risks in the technology industry, including serving as the acting chief security officer at a public company and holding other senior cybersecurity leadership and operational roles at other companies. Our CISO holds an undergraduate degree in computer engineering and graduate degrees in electrical engineering and business administration. Our CFO, CLO, VP of Internal Audit, and VP of Ethics, Compliance and Risk Management each hold undergraduate and/or graduate degrees in their respective fields, and have over 10 years of experience managing risks at the Company and at similar companies, including risks arising from cybersecurity threats.
Item 2. Properties
We lease all of our facilities and do not own any real property. Our headquarters, which serves as our principal offices for our business segments, is located in San Francisco, California, where we actively occupy 83,372 square feet of office space at 101 Spear Street. In 2022, we announced our decision to become a remote-first company allowing our employees the flexibility to work remotely on a permanent basis. As a result of this decision, we permanently closed several of our offices, including a portion of our headquarters space. The financial impact on our results of operations from closing these offices is described in Note 6 and Note 10 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
We lease additional office space in various other locations in South America, Europe and Asia. This includes our international headquarters in Dublin, Ireland, and regional offices used for business operations, sales, support, and product development for our business segments. Additional information regarding our lease commitments is available in Note 10 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
We believe that our remaining facilities are adequate and suitable for our current needs and that, should it be needed, suitable additional or alternative space will be available to accommodate our operations.
Item 3. Legal Proceedings
Refer to Note 17(b) to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a description of our current material legal proceedings.

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
Market Information for Common Stock
Our Class A common stock (“common stock”) is traded on the New York Stock Exchange under the symbol “TWLO.” Our Class B common stock is neither listed nor traded, and no Class B common stock is currently issued or outstanding.
Holders of Record
As of January 31, 2024, we had 251 holders of record of our Class A common stock. There are no holders of record of our Class B common stock. The actual number of stockholders is greater than this number of holders of record and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees.
Dividend Policy
We have never declared or paid any cash dividends on our capital stock. We intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future.
Stock Performance Graph
This performance graph shall not be deemed "soliciting material" or to be "filed" with the SEC for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities under that Section, and shall not be deemed to be incorporated by reference into any filing of Twilio Inc. under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act.
We have presented below the cumulative five-year total return to our stockholders in comparison to the S&P 500 Index and S&P 500 Information Technology Index. An investment of $100 (with reinvestment of all dividends) is assumed to have been made in our common stock and in each respective index at the market closing price on the last trading day for the fiscal year ended December 31, 2018, and its relative performance is tracked through the last trading day for the fiscal year ended December 31, 2023.

Sales of Unregistered Securities
During the year ended December 31, 2023, we issued 88,408 shares of our unregistered common stock to an independent donor advised fund to further our Twilio.org philanthropic goals. The shares were “restricted securities” for purposes of Rule 144 under the Securities Act, and had an aggregate fair market value on the date of donation of $5.3 million. The foregoing transaction did not involve any underwriters, any underwriting discounts or commissions, or any public offering. We believe the offer, sale and issuance of the above shares were exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act because the issuance of the shares did not involve a public offering.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, the following discussion contains forward-looking statements that are based upon current plans, expectations and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.
Overview
We enable businesses of all sizes to revolutionize how they engage with their customers by delivering seamless, trusted and personalized customer experiences at scale. Our leading customer engagement platform comprises communications APIs that enable developers to embed numerous forms of messaging, voice, and email interactions into their customer-facing applications, as well as software products that target specific engagement needs, including our customer data platform, digital engagement centers, marketing campaigns and advanced account security solutions. This combination of flexible APIs and software solutions helps businesses of all sizes and across numerous industries to benefit from smarter and more streamlined engagement at every step of the customer journey, including reduced customer acquisition costs, lasting loyalty and increased customer value. Our platform, which combines our highly customizable communications APIs with customer data management capabilities, allows businesses to break down data silos and build a comprehensive single source for their customer data that is organized into unique profiles that are easily accessible by all their business teams. Empowered with this information and the insights it enables, businesses using our platform can provide robust, personalized and effective communications to their customers at every stage of their customer relationships. The value proposition of our offerings has become stronger and our
50


products have become more strategic to our customers as more and more businesses have prioritized building more personalized and more differentiated customer engagement experiences through digital channels.
In February 2023, we began operating our business in two business units: Communications and Data & Applications, which has since been renamed Segment. Our Communications business consists of a variety of APIs and software solutions to optimize communications between our customers and their end users. Our key Communications offerings include Messaging, Voice, Email, Flex, Marketing Campaigns, and User Identity and Authentication. Our Segment business consists of software products that enable businesses to leverage their first-party data to create unique customer profiles and achieve more effective customer engagement. Our key Segment offerings are Segment and Engage. Together, our Communications and Segment products power our customer engagement platform. We believe that our two business units are complementary and address adjacent needs and related problems for our customers. Our goal is to create a flywheel for effective customer engagement by combining Segment’s user profiles with our rich Communications data to drive more personalized and intelligent customer interactions. We believe that our business unit structure enables each business unit to execute toward its respective goals with appropriate focus and independence, best positioning us to achieve our long-term plan of creating the leading customer engagement platform.

For a comprehensive overview of our business, our platform and our products refer to Part I, Item 1, “Business,” included elsewhere in this Annual Report on Form 10-K.

In the years ended December 31, 2023, 2022, and 2021, our revenue was $4.2 billion, $3.8 billion and $2.8 billion, respectively, and our net loss was $1.0 billion, $1.3 billion and $949.9 million, respectively. In the years ended December 31, 2023, 2022, and 2021, our 10 largest Active Customer Accounts generated an aggregate of 10%, 12% and 11% of our total revenue, respectively.
Recent Developments
Business Unit Reorganization. In February 2023, we began operating our business in two business units: Twilio Communications (“Communications”) and Twilio Data & Applications (“Data & Applications”). We determined that as of the end of the second quarter of 2023 we had two operating and reportable segments, Communications and Data & Applications, and that our segment measure of profitability was non-GAAP gross profit.
In the fourth quarter of 2023, we further modified the organization of our business units by moving our Flex and Marketing Campaigns products from the Data & Applications reportable segment into the Communications reportable segment. We also renamed our Data & Applications segment to Segment. The fourth quarter reorganization did not change our reportable segment structure; however, it changed the reporting unit structure within our operating segments. Reporting units are the level below the operating segment level at which we allocate and test goodwill. As a result of these changes, we reallocated goodwill to the newly formed reporting units after each reorganization. We were required to test goodwill for impairment immediately before and immediately after each time our reporting unit structure changed. In the second quarter of 2023, we performed a goodwill impairment assessment immediately before and immediately after the reorganization and the change in the reporting unit structure and concluded that goodwill was not impaired.
Prior to testing goodwill in the fourth quarter of 2023, we identified a change in Segment’s performance, which indicated that certain intangible assets in our Segment reportable segment may not be recoverable. We performed an impairment assessment, as required by the accounting guidance, and recorded a $285.7 million aggregate impairment loss related to Segment’s developed technology and customer relationship intangible assets. We engaged an external expert to assist us with the valuation analysis. The loss is recorded in the impairment of long-lived assets line item of our consolidated financial statements for the year ended December 31, 2023, included elsewhere in this Annual Report on Form 10-K.
After the impairment loss was recorded in the fourth quarter of 2023, we performed a goodwill impairment assessment and concluded that goodwill was not impaired immediately before and immediately after the reorganization and the change in the reporting unit structure.
Further, in January 2024, our newly appointed Chief Executive Officer (“CEO”), who is also our Chief Operating Decision Maker (“CODM”), began reviewing segment operating results using non-GAAP income from operations as the segment measure of profitability. As such, we have disclosed our segment related information to reflect management’s current view of the business.

Refer to Note 6, Note 8 and Note 12 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information on the restructuring, impairment and segment reporting.

Share Repurchase Program. In February 2023, our board of directors authorized a share repurchase program pursuant to which we may repurchase up to $1.0 billion in aggregate value of our common stock until the program expires on December 31, 2024. Repurchases under this program can be made through open market, private transactions or other means in compliance with applicable federal securities laws and could include repurchases pursuant to Rule 10b5-1 trading plans. We have discretion in determining the conditions under which shares may be repurchased from time to time.
In the year ended December 31, 2023, we repurchased $672.1 million in aggregate value, or 11.3 million shares, of our common stock under this program. As of December 31, 2023, approximately $327.9 million of the originally authorized amount remained available for future repurchases.
Workforce Reduction Plans. In February 2023, we announced a workforce restructuring plan (the “February 2023 Plan”) to eliminate approximately 17% of our workforce. The execution of the February 2023 Plan was substantially completed in the first quarter of 2023. In December 2023, we announced another restructuring plan (the “December 2023 Plan”) to further eliminate approximately 5% of our workforce. In the year ended December 31, 2023, the cumulative restructuring expenses incurred under the February 2023 Plan and December 2023 Plan were $165.7 million and were related to employee severance, benefits, vesting of equity awards and facilitation costs. The estimated remaining expenses related to both plans are not expected to be significant. For additional details refer to Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
Sabbatical Program. In February 2023, we announced that we will be sunsetting our employee sabbatical program that we introduced effective July 1, 2022. The sabbatical program was intended to provide our tenured employees with a paid leave of four consecutive weeks after every three years of service. Employees who had accumulated more than three years of service as of the program’s effective date became eligible for their benefit immediately. As of December 31, 2023, the remaining liability of $5.5 million related to the accumulated benefits for employees who remain eligible under this program until its expiration. As of December 31, 2022, the accrued sabbatical liability was $30.7 million.
Remote-First Company. In 2022, we announced our decision to become a remote-first company, allowing our employees the flexibility to work remotely on a permanent basis. As part of our new operating strategy, we permanently closed several of our offices in 2022 and 2023. These office closures resulted in an impairment of several long-lived assets, including our operating lease assets, leasehold improvements and property and equipment. In the year ended December 31, 2023, we recorded a total impairment loss of $34.8 million related to our permanent office closures.
Impairment of Strategic Investment. In the first quarter of 2023, we recorded a $46.2 million impairment loss associated with one of our investments from 2021 to reduce its carrying amount to fair value.
Divestiture of IoT Assets. In the second quarter of 2023, we completed the sale of our IoT asset group for a stock consideration of $15.8 million. The loss on divestiture and related expenses recorded in the year ended December 31, 2023 were not significant.
Divestiture of ValueFirst Business. In the third quarter of 2023, we completed the sale of our ValueFirst business for a total cash sales price of $45.5 million, or $38.2 million in proceeds, net of cash divested. In the year ended December 31, 2023, we recorded a $28.8 million loss on divestiture and an additional $3.3 million in related expenses. For additional details refer to Note 5 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
Factors Affecting Our Results of Operations
We are focused on profitable growth. To increase revenue and grow market share, we intend to further enhance our ISV relationships, improve our self-service capabilities, cross-sell our products, drive product innovation, expand internationally, and enhance Segment interoperability. We also intend to optimize our business and take measures to reduce costs, including simplifying our business processes, modernizing our infrastructure, focusing on self-service, leveraging AI, and implementing other initiatives targeted at improving efficiencies in our business. We are also conducting an operational review of our Segment business, which we expect to complete in March 2024.
Our revenue is primarily derived from usage-based fees, which can lead to variability in our results of operations and at times create differences between our forecasts and actual results. Our usage-based revenue is also more immediately impacted by changes in consumer spending and macroeconomic conditions than our subscription-based revenue.
Our gross margin is impacted by a number of factors, including the timing and extent of our investments in our operations; our product mix; our ability to manage our cloud infrastructure‑related and network service provider fees, including
52


A2P SMS fees; the mix of U.S. revenue compared to international revenue; changes in foreign exchange rates; the timing of amortization of capitalized software development costs and acquired intangibles; and the extent to which we periodically choose to adjust prices of our products.
Our gross profit is impacted by our product mix. Our cost of revenue and gross profit are also impacted by changes in hosting fees and network service providers’ fees and our ability to pass these costs through to our customers. We also experience seasonal trends due to increased consumer activity in the fourth quarter, which may result in lower sequential revenue in the first quarter.
We are winding down our video product and the software component of our Zipwhip business in 2024, which we expect will negatively impact revenue growth rates in 2024.
We are also migrating part of Segment’s architecture to a new infrastructure provider in 2024, which we expect to allow us to recognize greater operational efficiency and scale up new AI-driven products and features. We expect this migration will take several quarters and result in overlapping expenses with our original and new vendors for much of 2024, which we expect to negatively impact Segment gross margins until we complete the migration.
We expect our recent workforce restructurings and recent office closures will reduce our operating expenses. We are also modifying our employee compensation program by introducing a new cash bonus program and reducing or eliminating our use of equity compensation for certain employees, which will primarily impact our expenses commencing in the first quarter of 2024.
Key Business Metrics
We review a number of operational and financial metrics, including Active Customer Accounts and Dollar-Based Net Expansion Rate, to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions.
The following table summarizes our year-over-year revenue growth and Dollar-Based Net Expansion Rate for the years ended December 31, 2023, 2022 and 2021, and the number of Active Customer Accounts as of December 31, 2023, 2022 and 2021.

Total Revenue Growth Rate%35 %61 %
Dollar-Based Net Expansion Rate103 %121 %131 %
Active Customer Accounts
We define an Active Customer Account at the end of any period as an individual account, as identified by a unique account identifier, for which we have recognized at least $5 of revenue in the last month of the period. A single organization may constitute multiple unique Active Customer Accounts if it has multiple account identifiers, each of which is treated as a separate Active Customer Account. Active Customer Accounts excludes customer accounts from Zipwhip, Inc. (“Zipwhip”). Communications Active Customer Accounts and Segment Active Customer Accounts are calculated using the same methodology, but using only revenue recognized from accounts in the respective segment. When presented in this Annual Report on Form 10-K, (i) the number of Active Customer Accounts is rounded down to the nearest thousand, (ii) the number of Communications Active Customer Accounts is rounded down to the nearest thousand, and (iii) the number of Segment Active Customer Accounts is rounded down to the nearest hundred.
We believe that the number of Active Customer Accounts, on an aggregate basis and at the segment level, is an important indicator of the growth of our business, the market acceptance of our platform and future revenue trends. We believe that use of our platform by customers at or above the $5 per month threshold is a stronger indicator of potential future engagement than trial usage of our platform or usage at levels below $5 per month. In the three years ended December 31, 2023, 2022 and 2021, revenue from Active Customer Accounts represented over 99% of total revenue in each period.
53


Dollar‑Based Net Expansion Rate
Our Dollar-Based Net Expansion Rate compares the total revenue from all Active Customer Accounts and customer accounts from Zipwhip in a quarter to the same quarter in the prior year. To calculate the Dollar-Based Net Expansion Rate, we first identify the cohort of Active Customer Accounts and customer accounts from Zipwhip that were Active Customer Accounts or customer accounts from Zipwhip in the same quarter of the prior year. The Dollar-Based Net Expansion Rate is the quotient obtained by dividing the revenue generated from that cohort in a quarter, by the revenue generated from that same cohort in the corresponding quarter in the prior year. When we calculate Dollar-Based Net Expansion Rate for periods longer than one quarter, we use the average of the applicable quarterly Dollar-Based Net Expansion Rates for each of the quarters in such period. Revenue from acquisitions does not impact the Dollar-Based Net Expansion Rate calculation until the quarter following the one-year anniversary of the applicable acquisition, unless the acquisition closing date is the first day of a quarter. As a result, for the year ended December 31, 2023, our Dollar-Based Net Expansion Rate excludes the contributions from acquisitions made after October 1, 2022. Revenue from divestitures does not impact the Dollar-Based Net Expansion Rate calculation beginning in the quarter the divestiture closed, unless the divestiture closing date is the last day of a quarter. As a result, for the year ended December 31, 2023, our Dollar-Based Net Expansion Rate excludes the contributions from divestitures made after December 31, 2022. Communications Dollar-Based Net Expansion Rate and Segment Dollar-Based Net Expansion Rate are calculated using the same methodology, but using only revenue attributable to the respective segment and Active Customer Accounts and customer accounts from Zipwhip for that respective segment.
We believe that measuring Dollar-Based Net Expansion Rate, on an aggregate basis and at the segment level, provides an important indication of the performance of our efforts to increase revenue from existing customers. Our ability to drive growth and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with existing Active Customer Accounts and to increase their use of the platform. An important way in which we have historically tracked performance in this area is by measuring the Dollar-Based Net Expansion Rate for Active Customer Accounts. Our Dollar-Based Net Expansion Rate increases when such Active Customer Accounts increase their usage of a product, extend their usage of a product to new applications or adopt a new product. Our Dollar-Based Net Expansion Rate decreases when such Active Customer Accounts cease or reduce their usage of a product or when we lower usage prices on a product. As our customers grow their businesses and extend the use of our platform, they sometimes create multiple customer accounts with us for operational or other reasons. As such, when we identify a significant customer organization (defined as a single customer organization generating more than 1% of revenue in a quarterly reporting period) that has created a new Active Customer Account, this new Active Customer Account is tied to, and revenue from this new Active Customer Account is included with, the original Active Customer Account for the purposes of calculating this metric.
Key Components of Statements of Operations
Revenue
Revenue. We recognize revenue from our products on either a usage basis or a subscription basis, depending on the nature of the product and the type of customer contract. Our reportable segments contain products that may follow either revenue recognition model.
The majority of our Communications segment revenue is derived from usage-based fees. The usage-based fees are earned when customers access our cloud-based platform and start using the products. Some examples of our usage-based products are Messaging and Voice. For Messaging products, we primarily charge fees related to the number of text messages sent or received. For Voice products, we primarily charge fees for minutes of call duration. Some examples of the subscription-based Communications products are Email, Marketing Campaigns and Flex. For these products we recognize revenue evenly over the contract term.
Our Segment segment revenue is derived from Segment and Engage products that are subscription-based. For these products we recognize revenue evenly over the contract term. When our usage-based products are embedded into our subscription-based products, we charge for each product separately on a usage or subscription basis, respectively, and record the revenue in the reportable segment in which each product resides.
54


Most of our usage-based customers gain access to our products and solutions through our e-commerce self-service sign-up format, which requires an upfront prepayment via credit card that is drawn down as they use our products. Pricing is generally based on a publicly available, self-serve pricing matrix that generally allows customers to receive tiered discounts as their usage of our products increases. Many of our larger usage-based customers enter into contractual arrangements with us for a period of at least 12 months. These contracts may include negotiated terms and typically include minimum revenue commitments of varying durations. Usage-based customers subject to such contracts are typically invoiced monthly in arrears for products used. In the years ended December 31, 2023, 2022 and 2021, we generated 71%, 73% and 72% of our revenue, respectively, from usage-based fees.
Subscription-based fees are earned in accordance with subscription pricing terms. For our subscription-based products, customers generally enter into negotiated contracts, which are typically one to three years in duration. Subscription customers are generally invoiced in advance at the start of the contract term. In the years ended December 31, 2023, 2022 and 2021, we generated 29%, 27% and 28% of our revenue, respectively, from non-usage‑based fees.
Amounts that have been charged via credit card or invoiced are recorded in revenue, deferred revenue or customer deposits, depending on whether the revenue recognition criteria have been met. Our deferred revenue and customer deposits liability balance is not a meaningful indicator of our future revenue at any point in time because the number of contracts with our invoiced customers that contain terms requiring any form of prepayment is not significant.
We define U.S. revenue as revenue from customers with IP addresses or mailing addresses at the time of registration in the United States. We define international revenue as revenue from customers with IP addresses or mailing addresses at the time of registration outside of the United States.
Cost of Revenue and Gross Profit
Cost of Revenue. Cost of revenue consists primarily of fees paid to network service providers. Cost of revenue also includes cloud infrastructure fees, direct costs of personnel, such as salaries and stock‑based compensation for our customer support employees, and other non‑personnel costs, such as depreciation and amortization expense related to data centers and hosting equipment, and amortization of capitalized internal-use software development costs and acquired intangible assets. Costs of revenue are generally directly attributable to each segment. Certain costs of revenue are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs.
Our arrangements with network service providers require us to pay fees based on the volume of phone calls initiated or text messages sent, as well as the number of telephone numbers acquired by us to service our customers. Our arrangements with our cloud infrastructure providers require us to pay fees based on our server capacity consumption.
Gross Profit. Gross profit represents revenue less cost of revenue.
Operating Expenses
The most significant components of operating expenses are personnel costs, which consist of salaries, benefits, sales commissions and bonuses and stock‑based compensation. We also incur other non‑personnel costs related to our general overhead expenses.
Research and Development. Research and development expenses consist primarily of personnel costs, outsourced engineering services, cloud infrastructure fees for staging and development of our products, depreciation, amortization of capitalized internal-use software development costs and an allocation of our general overhead expenses. We capitalize the portion of our software development costs that meets the criteria for capitalization. Research and development expenses are generally directly attributable to each segment. Certain research and development expenses are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs. A small percentage of research and development costs, such as costs related to digital architecture and information security, are not allocated to segments because they support company-wide processes and are managed on a company-wide level.
We are focusing our research and development investment in the highest impact product areas for our future. We are investing strategically in alignment with our focus on building a trusted, leading customer engagement platform.
55


Sales and Marketing. Sales and marketing expenses consist primarily of personnel costs, including commissions and bonuses to our sales employees. Sales and marketing expenses also include expenditures related to advertising, marketing, brand awareness activities, costs related to our SIGNAL customer and developer conferences, credit card processing fees, professional services fees, depreciation, amortization of acquired intangible assets and an allocation of our general overhead expenses. Sales and marketing expenses are generally directly attributable to each segment. Certain sales and marketing expenses are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs. A small percentage of sales and marketing costs, such as costs related to corporate communications and global brand awareness, are not allocated to segments because they support company-wide processes and are managed on a company-wide level.
We focus our sales and marketing efforts on generating awareness of our company, platform and products, creating sales leads and establishing and promoting our brand, both domestically and internationally.
General and Administrative. General and administrative expenses consist primarily of personnel costs for our accounting, finance, legal, human resources and administrative support personnel. General and administrative expenses also include costs related to business acquisitions and dispositions, legal and other professional services fees, certain taxes, depreciation and amortization, charitable contributions and an allocation of our general overhead expenses. General and administrative expenses are allocated to each segment when they are directly attributable to each segment or are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs. A significant portion of general and administrative costs, such as costs related to corporate governance, legal and certain finance and accounting functions, support company-wide processes and are managed on a company-wide level and, therefore, are considered corporate costs and are not allocated to segments.
We expect that we will incur costs associated with supporting the growth of our business. We may also incur higher than usual losses related to deterioration of quality of certain financial assets caused by macroeconomic conditions.
Restructuring Costs. Restructuring costs consist primarily of personnel costs, such as employee severance payments, benefits and certain facilitation costs, associated with our workforce reductions, which are described in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Restructuring costs also include stock-based compensation expense related to vesting of stock-based awards of the impacted employees.
Impairment of Long-Lived Assets. Impairment of long-lived assets consists of impairment of intangible assets and certain operating right-of-use assets and the associated leasehold improvements and property and equipment when the carrying amounts exceed their respective fair values.
Other Expenses, Net
Our other expenses, net consist primarily of our share of losses from our equity method investment; impairment charges and gains and losses related to our strategic investments and marketable securities, including interest income; and debt-related costs, including interest expense.
(Provision for) Benefit From Income Taxes
Our (provision for) benefit from income taxes consists primarily of income taxes, withholding taxes in foreign jurisdictions in which the Company conducts business and tax benefits related to the release of valuation allowance from historically completed acquisitions.
The primary difference between our effective tax rate and the federal statutory rate relates to the valuation allowance the Company established on the federal, state and certain foreign net operating losses and credits.

Non-GAAP Financial Measures
We use the following non‑GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non‑GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance, facilitates period‑to‑period comparisons of results of operations and assists in comparisons with other companies, many of which use similar non‑GAAP financial information to supplement their results of operations reported in accordance with generally accepted accounting principles (“GAAP”). Non‑GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP and may be different from similarly‑titled non‑GAAP measures used by other companies. Whenever we use a non‑GAAP financial measure, a reconciliation is provided to the most closely applicable financial measure stated in accordance with GAAP. The users of our consolidated financial statements are encouraged to review the related GAAP financial measures and the reconciliation of these non‑GAAP financial measures to their most directly comparable GAAP financial measures.

2023 compared to 2022
In 2023, research and development expenses decreased by $136.3 million, or 13%, compared to the same period last year. The decrease was primarily attributable to a $140.7 million decrease in total personnel costs, which was mostly driven by the restructuring of our workforce in September 2022, February 2023 and December 2023, that contributed to an 8% decrease in average research and development headcount in 2023. For further detail on the restructuring plans refer to Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
In 2023, sales and marketing expenses decreased by $225.0 million, or 18%, compared to the same period last year. The decrease was primarily attributable to a $183.2 million decrease in total personnel costs, which was mostly driven by the restructuring of our workforce in September 2022, February 2023 and December 2023, that contributed to a 14% decrease in average sales and marketing headcount in 2023. Sales and marketing expenses also decreased due to a $21.5 million decrease in advertising expenses. For further detail on the restructuring plans refer to Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
62


In 2023, general and administrative expenses decreased by $49.0 million, or 9%, compared to the same period last year. The decrease was primarily attributable to a $78.1 million decrease in total personnel costs, which was mostly driven by the restructuring of our workforce in September 2022, February 2023 and December 2023, that contributed to a 21% decrease in average general and administrative headcount in 2023. These decreases were partially offset by a $32.3 million loss on divestiture related to the sale of our ValueFirst business and our IoT asset group. For further detail on the restructuring plans and divestitures, refer to Note 7 and Note 5, respectively, to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
In 2023, restructuring costs increased by $89.1 million, or 116%, compared to the same period last year. The increase was primarily attributable to our restructuring activities under the February 2023 Plan and December 2023 Plan, which collectively had a more substantial financial impact than our restructuring activities undertaken in September 2022. For further detail refer to Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
In 2023, impairment of long-lived assets increased by $222.8 million, or 228%, compared to the same period last year. The increase was primarily attributable to the impairment of Segment intangible assets of $285.7 million in 2023, as a result of the performance of our Segment segment described in detail in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. This increase was partially offset by a $62.9 million decrease in impairments of operating right-of-use assets and property and equipment due to fewer office closures in 2023 compared to 2022.
2022 compared to 2021
In 2022, research and development expenses increased by $289.9 million, or 37%, compared to the same period in the prior year. The increase was primarily attributable to a $264.4 million increase in personnel costs, net of capitalized costs, largely as a result of a 33% increase in average research and development headcount as we continued to focus on enhancing our Segment and Flex products and strengthening our platform infrastructure.
In 2022, sales and marketing expenses increased by $203.4 million, or 19%, compared to the same period in the prior year. The increase was primarily attributable to a $175.5 million increase in personnel costs, largely as a result of a 26% increase in average sales and marketing headcount as we continued to expand our sales efforts globally. The increase was also due to a $13.4 million increase in advertising expenses.
In 2022, general and administrative expenses increased by $45.0 million, or 10%, compared to the same period in the prior year. The increase was primarily attributable to a $32.0 million increase in personnel costs, comprised of a $29.9 million, or 20%, increase in personnel costs before stock-based compensation, and a $2.0 million increase in stock-based compensation. The increase in personnel costs were largely a result of a 21% increase in average general and administrative headcount to support the growth of our business globally. The increase was also attributable to a $28.3 million increase in our bad debt expense. These increases were partially offset by a $21.6 million decrease in charitable contribution expense that we made through Twilio.org.
In 2022, we incurred $76.6 million in restructuring costs as a result of restructuring activities undertaken in September 2022, as described in Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
In 2022, we incurred $97.7 million in impairment charges related to our operating lease assets and other long-lived assets. The impairment charges were triggered by office closures in 2022 as described in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

In 2023, other expenses, net, increased by $81.9 million, or 214%, compared to the same period last year. The increase was primarily attributable to a $86.6 million increase in our share of losses from our equity method investment and a $46.2 million increase related to an impairment of a strategic investment, partially offset by a $53.8 million increase in income related to our investments. For further detail refer to Notes 3 and 11 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
2022 compared to 2021
In 2022, other expenses, net, decreased by $7.0 million, or 15%, compared to the same period in the prior year. The decrease was attributable to the $29.0 million loss from debt extinguishment in 2021 that did not recur in 2022, and a $13.3 million increase in interest income related to our investments, which was partially offset by a $35.3 million increase in our share of losses from our equity method investment. The net decrease in the remaining other expenses, net, categories were not significant either individually or in the aggregate. For further detail refer to Notes 3 and 11 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
Segment Results of Operations
The following table presents the results for non-GAAP operating income (loss), as reviewed by our CODM, for each of our Communications and Segment segments for the years ended December 31, 2023, 2022 and 2021:

2023 compared to 2022
In 2023, Communications non-GAAP income from operations increased by $523.3 million, or 164%, compared to the same period last year. The increase was driven by an increase in Communications revenue of $308.6 million, as described in the Revenue section above, and a decrease in Communications operating expenses, partially offset by an increase in Communications cost of revenue. The decrease in operating expenses was primarily attributable to a $254.1 million decrease in total Communications personnel costs, which was mainly due to the restructuring of our workforce in September 2022, February 2023 and December 2023, that contributed to a 16% decrease in average Communications headcount in 2023. The increase in Communications cost of revenue was primarily attributable to a $19.5 million increase in hosting fees and a $51.3 million increase in network service providers’ costs, net of the impact of hedging instruments, to support the increase in revenue due to the growth in usage of our products by our new and existing customers.
64


In 2023, Segment non-GAAP loss from operations increased by $42.7 million, or 144%, compared to the same period last year. The increase was driven by an increase in Segment operating expenses and cost of revenue, partially offset by an increase in Segment revenue of $19.0 million, as described in the Revenue section above. The increase in operating expenses was primarily attributable to a $25.2 million increase in total Segment personnel costs, which was mainly due to a 12% increase in average Segment headcount in 2023, as we continued to focus on enhancing our Segment product and expanding our sales efforts. The increase in Segment cost of revenue was primarily attributable to a $9.2 million increase in hosting fees and a $4.9 million increase in amortization of capitalized internal-use software development costs.
2022 compared to 2021
In 2022, Communications non-GAAP income from operations increased by $42.2 million, or 15%, compared to the same period in the prior year. The increase was driven by an increase in Communications revenue of $909.2 million, as described in the Revenue section above, offset by an increase in Communications operating expenses and Communications cost of revenue. The increase in operating expenses was primarily attributable to a $259.6 million increase in Communications personnel costs, largely as a result of a 26% increase in average Communications headcount as we continued to focus on enhancing our products and expanding our sales efforts globally, a $24.9 million increase in bad debt expense, a $16.2 million increase in software subscription costs, and an $11.1 million increase in travel related expenses. The increase in Communications cost of revenue was primarily attributable to a $477.0 million increase in network service providers’ costs, including the impact of hedging instruments, a $30.7 million increase in hosting fees, and a $14.7 million increase in support costs, all of which supported the growth in usage of our products by new and existing customers. The net increase in the remaining operating expenses and cost of revenue categories were not significant either individually or in the aggregate.
In 2022, Segment non-GAAP loss from operations increased by $16.7 million, or 128%, compared to the same period in the prior year. The increase was driven by an increase in Segment operating expenses and Segment cost of revenue, offset by an increase in Segment revenue of $75.3 million, as described in the Revenue section above. The increase in operating expenses was primarily attributable to a $67.9 million increase in Segment personnel costs, largely as a result of a 50% increase in average Segment headcount as we continued to focus on enhancing our products and expanding our sales efforts globally, and a $9.1 million increase in advertising costs. The increase in Segment cost of revenue was primarily attributable to a $10.2 million increase in hosting fees and a $5.8 million increase in support costs.
Liquidity and Capital Resources
As of December 31, 2023, we had cash and cash equivalents of $655.9 million and short-term marketable securities of $3.4 billion. Cash equivalents consist of money market funds. Short-term marketable securities consist primarily of U.S. treasury securities, non-U.S. government securities, high credit quality corporate debt securities and commercial paper. The cash and cash equivalents and short-term marketable securities are held for working capital purposes.
Our principal sources of liquidity have been (i) the net proceeds of $979.0 million, $1.4 billion and $1.8 billion, net of underwriting discounts and offering expenses paid by us, from our public equity offerings in June 2019, August 2020 and February 2021, respectively; (ii) the aggregate net proceeds of approximately $984.7 million, after deducting purchaser discounts and debt issuance costs paid by us, from the issuance of our 2029 Notes and 2031 Notes in March 2021 (each, as defined below); (iii) the net proceeds of $228.4 million, after deducting transaction costs paid by us, from settlement of our capped call arrangements in June 2021; and (iv) the payments received from customers using our products.
Our primary uses of cash include operating costs, such as personnel-related costs, network service provider costs, cloud infrastructure costs, facility-related spending, as well as, from time to time, acquisitions, investments and share repurchases. Our principal contractual and other commitments consist of obligations under our 2029 Notes and 2031 Notes, our operating leases for office space that we occupy, sublease or hold to sublease, and contractual commitments to our cloud infrastructure and network service providers. Refer to Note 10, Note 14 and Note 17(a) to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for discussions of our obligations and commitments related to leases, debt and other purchase obligations.
We may, from time to time, consider acquisitions of, or investments in, complementary businesses, products, services, capital infrastructure or technologies which might affect our liquidity requirements or cause us to secure additional financing or issue additional equity or debt securities. There can be no assurance that additional credit lines or financing instruments will be available in amounts or on terms acceptable to us, if at all.
65


We believe that our cash, cash equivalents and marketable securities balances, as well as the cash flows generated by our operations, will be sufficient to satisfy our anticipated cash needs for working capital and capital expenditure needs, including authorized share repurchases, for the next 12 months and beyond. However, our belief may prove to be incorrect, and we could utilize our available financial resources sooner than we currently expect. We may be required to seek additional equity or debt financing in order to meet our future capital requirements. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital when desired, our business, results of operations and financial condition would be adversely affected. Our future capital requirements, the adequacy of our available funds and our cash from operations depend on many factors and are affected by various risks and uncertainties, including those set forth in Part I, Item 1A, “Risk Factors.”
Share Repurchase Program
In February 2023, our board of directors authorized a share repurchase program pursuant to which we may repurchase up to $1.0 billion in aggregate value of our common stock. Repurchases under the program will be made through open market, private transactions or other means in compliance with applicable federal securities laws, and could include repurchases pursuant to Rule 10b5-1 trading plans. We have discretion in determining the conditions under which shares may be repurchased from time to time. The program expires on December 31, 2024.
In the year ended December 31, 2023, we purchased $672.1 million in aggregate value, or 11.3 million shares, of our common stock on the open market under this program. As of December 31, 2023, approximately $327.9 million of the originally authorized amount remains available for future repurchases.
2029 Notes and 2031 Notes
In March 2021, we issued and sold $1.0 billion aggregate principal amount of senior notes, consisting of $500.0 million principal amount of 3.625% notes due 2029 (the “2029 Notes”) and $500.0 million principal amount of 3.875% notes due 2031 (the “2031 Notes,” and together with the 2029 Notes, the “Notes”). These Notes are described in detail in Note 14 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Cash Flows from Operating Activities
In 2023, cash provided by operating activities consisted primarily of our net loss of $1.0 billion adjusted for non-cash items, including $675.9 million of stock-based compensation expense, $284.4 million of depreciation and amortization expense, $320.5 million of impairment of intangible assets and other long-lived assets, $72.9 million amortization of deferred commissions, $27.0 million of non-cash reduction in our operating right-of-use asset, $121.9 million of share of losses from equity method investments, $51.9 million of provision for bad debt and $230.6 million of cumulative changes in operating assets and liabilities. With respect to changes in operating assets and liabilities, accounts receivable and prepaid expenses increased $141.4 million primarily due to revenue growth, timing of cash receipts and pre-payments of our cloud infrastructure fees and certain operating expenses. Accounts payable and other current liabilities decreased $39.4 million primarily driven by lower personnel-related accruals due to lower headcount, including a $25.2 million decrease in the sabbatical benefit accrual driven by lower headcount and the sunsetting of the program. The impairment of intangible assets and other long lived assets is described further in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
66


In 2022, cash used in operating activities consisted primarily of our net loss of $1.3 billion adjusted for non-cash items, including $798.6 million of stock-based compensation expense reflecting the impact of the September 2022 restructuring plan, $279.1 million of depreciation and amortization expense, $97.7 million of impairment of operating lease and other long-lived assets, $57.9 million of amortization of deferred commissions, $47.2 million of non-cash reduction in our operating right-of-use asset, $35.3 million of share of losses from equity method investments, $35.0 million of provision for bad debt, $33.2 million of net amortization of investment premium and discount and $396.6 million of cumulative changes in operating assets and liabilities. With respect to changes in operating assets and liabilities, accounts receivable and prepaid expenses increased $289.0 million primarily due to revenue growth, timing of cash receipts and pre-payments of our cloud infrastructure fees and certain operating expenses. Accounts payable and other current liabilities increased $105.8 million primarily due to increases in transaction volumes, and the impact from the then new sabbatical employee benefit that we introduced effective July 1, 2022. Operating lease liabilities decreased $54.5 million due to payments made against our operating lease obligations. Other long-term assets increased $146.5 million primarily due to an increase in the sales commissions balances related to the growth of our business. The impairment of operating lease and other long lived assets is described further in Note 6 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
Cash Flows from Investing Activities
In 2023, cash provided by investing activities was $228.6 million primarily consisting of $247.4 million of maturities and sales of marketable securities and other investments, net of purchases, and $38.2 million of proceeds from divestitures, net of cash divested, partially offset by $39.9 million related to capitalized software development costs and $11.3 million related to purchases of long-lived assets.
In 2022, cash used in investing activities was $616.5 million primarily consisting of $498.9 million of purchases of marketable securities and other investments, net of maturities and sales, $45.8 million related to capitalized software development costs, $37.4 million of net cash paid to acquire other businesses and $34.4 million related to purchases of long-lived assets.
Cash Flows from Financing Activities
In 2023, cash used in financing activities was $643.6 million primarily consisting of $668.8 million of cash paid to repurchase 11.3 million shares of our common stock in the open market, including related costs, offset by $43.8 million in proceeds from stock options exercised by our employees and shares issued under our employee stock purchase plan.
In 2022, cash provided by financing activities was $45.0 million primarily consisting of $59.6 million in proceeds from stock options exercised by our employees and shares issued under our employee stock purchase plan, offset by $13.4 million in principal payments on debt and finance leases.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.
We believe that the accounting policies, assumptions and estimates associated with revenue recognition have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.
See Note 2 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a discussion of our accounting policies.
Revenue Recognition
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowances for credits and any taxes collected from customers, which are subsequently remitted to governmental authorities.
67


Our revenue is derived from usage and non-usage based fees. Our usage-based fees are earned from certain of our Communications products when customers access our platform. Platform usage is considered a monthly series comprising one performance obligation and usage-based fees are recognized as revenue in the period in which the usage occurs.
Our subscription-based fees are derived from our software products, such as Segment, Engage, Flex, Email and Marketing Campaigns, and certain other non-usage-based contracts, such as with the sales of short codes and customer support. Non-usage-based contracts revenue is recognized on a ratable basis over the contractual term which is generally from one to three years.
Our arrangements do not contain general rights of return. However, credits may be issued on a case-by-case basis. Credits are accounted for as variable consideration, are estimated based on historical trends and are recorded against revenue. The contracts do not provide customers with the right to take possession of the software supporting the applications. Amounts that have been invoiced are recorded in accounts receivable and in revenue or deferred revenue depending on whether the revenue recognition criteria have been met.
Recent Accounting Pronouncements Not Yet Adopted
See Note 2(af) to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a discussion of recent accounting pronouncements not yet adopted.
Item 7A.Quantitative and Qualitative Disclosures about Market Risk
We are exposed to certain market risks in the ordinary course of our business, including sensitivities as follows:
Interest Rate Risk
We had cash and cash equivalents of $655.9 million and marketable securities of $3.4 billion as of December 31, 2023. In any given period, cash and cash equivalents may consist of bank deposits, money market funds, reverse repurchase agreements and commercial paper. Marketable securities consist primarily of U.S. treasury securities, non-U.S. government securities and high credit quality corporate debt securities. The cash and cash equivalents and marketable securities are held for working capital purposes. Such interest‑earning instruments carry a degree of interest rate risk. To date, fluctuations in interest income have not been significant. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. In March 2021, we issued $1.0 billion aggregate principal amount of our 2029 Notes and 2031 Notes carrying fixed interest rates of 3.625% and 3.875%, respectively. Due to the short‑term nature of our investments and fixed rate nature of our debt, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
Currency Exchange Risks
The functional currency of most of our foreign subsidiaries is the U.S. dollar. The local currencies of our foreign subsidiaries are the Australian dollar, the Bermuda dollar, the Brazilian real, the British pound, the Canadian dollar, the Colombian peso, the Czech Republic koruna, the Euro, the Hong Kong dollar, the Indian rupee, the Japanese yen, the Mexican peso, the Polish zloty, the Serbian dinar, the Singapore dollar and the Swedish krona.
The majority of our subsidiaries remeasure monetary assets and liabilities at period-end exchange rates, while non-monetary items are remeasured at historical rates. Revenue and expense accounts are remeasured at the average exchange rate in effect during the month in which a transaction occurs. If there is a change in foreign currency exchange rates, the conversion of our foreign subsidiaries’ financial statements into U.S. dollars would result in a realized gain or loss which is recorded in our consolidated statements of operations included elsewhere in this Annual Report on Form 10-K.
We enter into foreign currency derivative hedging transactions to mitigate our exposure to market risks that may result from changes in foreign currency exchange rates. For further information, refer to Note 9 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.
A hypothetical 10% change in foreign exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors
Twilio Inc.:
Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting
We have audited the accompanying consolidated balance sheets of Twilio Inc. and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
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, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
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 the accompanying Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion 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 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
70


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 Matter
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: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Evaluation of the sufficiency of audit evidence over revenue recognition
As discussed in Note 2(e) to the consolidated financial statements, the Company's revenue is derived from usage and non-usage-based fees earned from customers accessing the Company's cloud-based platform. As of December 31, 2023, the Company recorded $4.2 billion in revenues, a portion of which related to Programmable Messaging and Programmable Voice APIs. The Company’s revenue recognition process is highly automated, and revenue is recorded within the Company’s general ledger through reliance on customized and proprietary information technology (IT) systems.
We identified the evaluation of the sufficiency of audit evidence over revenue recognition related to the Company’s Programmable Messaging and Programmable Voice APIs as a critical audit matter. This matter required especially subjective auditor judgment because of the large number of information technology (IT) applications involved in the revenue recognition process. Auditor judgment was required in determining the nature and extent of audit evidence obtained over these information systems that process revenue transactions. Involvement of IT professionals with specialized skills and knowledge was required to assist with the performance and evaluation of certain procedures and determination of IT applications subject to testing.
The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over revenue recognition. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s Programmable Messaging and Programmable Voice revenue recognition process. We involved IT professionals with specialized skills and knowledge, who assisted in testing controls related to the Company’s general information technology and application controls related to the systems utilized within the Company’s Programmable Messaging and Programmable Voice revenue recognition process. For a sample of customer agreements, we compared the pricing reflected in the Company’s revenue IT system to the contractually agreed upon pricing with the customer. For a sample of revenue transactions, we compared the amounts recognized for consistency with underlying documentation, including contracts with customers. We assessed the recorded revenue by comparing revenue to underlying cash receipts. We evaluated credits issued after year end to assess the revenue recorded within the period. In addition, we evaluated the overall sufficiency of audit evidence obtained by assessing the results of procedures performed, including appropriateness of the nature and extent of such evidence.

TWILIO INC.
Notes to Consolidated Financial Statements
1. Organization and Description of Business
Twilio Inc. (the “Company”) was incorporated in the state of Delaware on March 13, 2008. Today's leading companies trust Twilio's Customer Engagement Platform (CEP) to build direct, personalized relationships with their customers everywhere in the world. Twilio enables companies to use communications and data to add intelligence and security to every step of their customers’ journey, from sales to marketing to growth, customer service and many more engagement use cases in a flexible, programmatic way.
The Company’s headquarters are located in San Francisco, California, and the Company has subsidiaries across North America, South America, Europe, Asia and Australia.
2. Summary of Significant Accounting Policies
(a)Basis of Presentation
The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).
(b)Principles of Consolidation
The consolidated financial statements include the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
(c)Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are used for, but not limited to, revenue allowances and sales credit reserves; recoverability of long-lived and intangible assets; capitalization and useful life of the Company’s capitalized internal-use software development costs; fair values of acquired intangible assets and goodwill; accruals and contingencies. Estimates are based on historical experience and on various assumptions that the Company believes are reasonable under current circumstances. However, future events are subject to change and best estimates and judgments may require further adjustments, therefore, actual results could differ materially from those estimates. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation.
(d)Concentration of Credit Risk
Financial instruments that potentially expose the Company to a concentration of credit risk consist primarily of cash, cash equivalents, restricted cash, marketable securities and accounts receivable. The Company maintains cash, restricted cash, cash equivalents and marketable securities with financial institutions. Certain balances held by such financial institutions exceed insured limits.
The Company sells its services to a wide variety of customers. If the financial condition or results of operations of any significant customer deteriorate substantially, the Company’s operating results could be adversely affected. To reduce credit risk, management performs credit evaluations of the financial condition of new customers and periodic re-evaluations, as needed, of existing customers. The Company does not require collateral from its credit customers and maintains reserves for estimated credit losses on customer accounts when considered necessary. Actual credit losses may differ from the Company’s estimates. During the years ended December 31, 2023, 2022 and 2021, no customer organization accounted for more than 10% of the Company’s total revenue.
As of December 31, 2023 and 2022, no customer organization represented more than 10% of the Company’s gross accounts receivable.
79


(e)Revenue Recognition
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowances for credits and any taxes collected from customers, which are subsequently remitted to governmental authorities.
The Company determines revenue recognition through the following steps:
Identification of the contract, or contracts, with a customer;
Identification of the performance obligations in the contract;
Determination of the transaction price;
Allocation of the transaction price to the performance obligations in the contract; and,
Recognition of revenue when, or as, the Company satisfies a performance obligation.
Nature of Products and Services
The Company recognizes revenue from its products on either a usage basis or a subscription basis, depending on the nature of the product and the type of customer contract. The Company’s reportable segments may contain products that follow either revenue recognition model.
The majority of the revenue in the Communications segment is derived from usage‑based fees. These fees are earned when customers access the Company’s cloud-based platform and start using the Company’s products. Platform access is considered a monthly series comprised of one performance obligation and usage-based fees are recognized as revenue in the period in which the usage occurs. Some examples of the usage-based products are Messaging and Voice. For the Messaging products, the fees relate to the number of text messages sent or received. For the Voice products, the fees primarily relate to minutes of call duration. In the years ended December 31, 2023, 2022 and 2021, the revenue from usage-based fees represented 71%, 73% and 72% of total revenue, respectively.
Subscription-based fees are derived from various products in both the Communications and Segment segments. Subscription-based products include products such as Segment, Engage, Flex, Email and others. Subscription-based contracts revenue is recognized on a ratable basis over the contractual term which is generally between one to three years. In the years ended December 31, 2023, 2022 and 2021, the revenue from non-usage-based fees represented 29%, 27%, and 28% of total revenue, respectively. When usage-based products are embedded into subscription-based products, the Company charges for each product separately and records the respective revenue into the reportable segment in which each product resides.
No significant judgments are required in determining whether products and services are considered distinct performance obligations and should be accounted for separately versus together, or to determine the stand-alone selling price.
The Company's arrangements do not contain general rights of return. However, credits may be issued on a case-by-case basis. The contracts do not provide customers with the right to take possession of the software supporting the applications. Amounts that have been invoiced are recorded in accounts receivable and in revenue or deferred revenue depending on whether the revenue recognition criteria have been met.
The Company defines U.S. revenue as revenue from customers with IP addresses or mailing addresses at the time of registration in the United States. The Company defines international revenue as revenue from customers with IP addresses or mailing addresses at the time of registration outside of the United States.
80


Remaining Performance Obligations
Revenue allocated to remaining performance obligations represents unearned revenue and amounts that were and will be invoiced and recognized as revenue in future periods for non-cancelable subscription arrangements with terms greater than one year. The Company applies the optional exemption of not disclosing the transaction price allocated to the remaining performance obligations for its usage-based contracts and contracts with original duration of less than one year. Revenue allocated to remaining performance obligations for contracts with durations of greater than one year was $144.0 million as of December 31, 2023, of which 67% is expected to be recognized over the next 12 months and 93% is expected to be recognized over the next 24 months.
(f)Deferred Revenue and Customer Deposits
Deferred revenue is recorded when a non-cancellable contractual right to bill exists or when cash payments are received in advance of future usage on non-cancelable contracts. Customer refundable prepayments are recorded as customer deposits. As of December 31, 2023 and 2022, the Company recorded $144.5 million and $139.1 million as its deferred revenue and customer deposits, respectively, that are included in deferred revenue and customer deposits in the accompanying consolidated balance sheets. During the years ended December 31, 2023, 2022 and 2021, the Company recognized $120.5 million, $124.9 million and $70.1 million of revenue, respectively, that was included in the deferred revenue and customer deposits balance as of the end of the previous year.
(g)Deferred Sales Commissions
The Company records an asset for the incremental costs of obtaining a contract with a customer, for example, sales commissions that are earned upon execution of contracts. The Company uses the portfolio of data method to determine the estimated period of benefit of capitalized commissions which is generally determined to be up to five years. Amortization expense related to these capitalized costs related to initial contracts, upsells and renewals, is recognized on a straight line basis over the estimated period of benefit of the capitalized commissions. The Company applies the optional exemption of expensing these costs as incurred with amortization periods of one year or less.
Total net capitalized commission costs as of December 31, 2023 and 2022, were $200.1 million and $239.1 million, respectively, and are included in prepaid expenses and other current assets and other long‑term assets in the accompanying consolidated balance sheets. Amortization of these assets was $72.9 million, $57.9 million and $31.5 million in the years ended December 31, 2023, 2022 and 2021, respectively, and is included in sales and marketing expense in the accompanying consolidated statements of operations.
(h)Cost of Revenue

Cost of revenue consists primarily of fees paid to network service providers. Cost of revenue also includes cloud infrastructure fees, direct costs of personnel, such as salaries and stock‑based compensation for our customer support employees, and other non‑personnel costs, such as depreciation and amortization expense related to data centers and hosting equipment, amortization of capitalized internal-use software development costs and acquired intangible assets. Costs of revenue are generally directly attributable to each segment. Certain costs of revenue are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs.
(i)Research and Development Expense
Research and development expenses consist primarily of personnel costs, outsourced engineering services, cloud infrastructure fees for staging and development of the Company’s products, depreciation, amortization of capitalized internal-use software development costs and an allocation of general overhead expenses. The Company capitalizes the portion of its software development costs that meets the criteria for capitalization. Research and development expenses are generally directly attributable to each segment. Certain research and development expenses are allocated to segments based on methodologies that best reflect the patterns of consumptions of these costs. Certain research and development costs are not allocated to segments because they support company-wide processes and are managed on a company-wide level.
81


(j)Internal-Use Software Development Costs
Certain costs of platform and other software applications developed for internal use are capitalized. The Company capitalizes qualifying internal-use software development costs that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (i) the preliminary project stage is completed and (ii) it is probable that the software will be completed and used for its intended function. Capitalization ceases when the software is substantially complete and ready for its intended use, including the completion of all significant testing. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Costs incurred for maintenance, minor upgrades and enhancements are expensed. Costs related to preliminary project activities and post-implementation operating activities are also expensed as incurred.
Capitalized costs of platform and other software applications are included in property and equipment. These costs are amortized over the estimated useful life of the software on a straight-line basis over three years. Management evaluates the useful life of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The amortization of costs related to the platform applications is included in cost of revenue, while the amortization of costs related to software applications developed for internal use is included in operating expenses.
(k)Advertising Costs
Advertising costs are expensed as incurred and were $71.1 million, $92.6 million and $78.8 million in the years ended December 31, 2023, 2022 and 2021, respectively. Advertising costs are included in sales and marketing expenses in the accompanying consolidated statements of operations.
(l)Restructuring Costs
The Company records restructuring expenses when management commits to a restructuring plan, the restructuring plan identifies all significant actions, the period of time to complete the restructuring plan indicates that significant changes to the plan are not likely and employees who are impacted have been notified of the pending involuntary termination.
(m)Stock-Based Compensation
All stock-based compensation to employees is measured on the grant date based on the fair value of these awards. This cost isthe awards on the date of grant. These costs are recognized as an expense following the straight-line attribution method over the requisite service period. This calculationThe Company uses the Black-Scholes option pricing model to measure the fair value of its stock options and the purchase rights issued under the Company's 2016 Employee Stock Purchase Plan, as amended (the “ESPP”). The fair value of the restricted stock units is performed for accounting purposesdetermined using the closing fair value of the Company's Class A common stock on the date of grant and reportedrecognized as an expense following straight-line attribution method over the requisite service period. Forfeitures are recorded in the executive compensation tables required byperiod in which they occur.
The Black-Scholes option pricing model requires the federal securities laws, even thoughuse of complex assumptions, which determine the recipientfair value of stock options and the purchase rights issued under the ESPP. If any of the awardsassumptions used in the Black-Scholes model change, stock-based compensation for future options may never realize anydiffer materially compared to that associated with previous grants. These assumptions include:
Fair value of the common stock. The Company uses the market closing price of its Class A common stock, as reported on the New York Stock Exchange, for the fair value.
Expected term. The expected term represents the period that the stock option or the purchase right is expected to be outstanding.

Compensation Risk Assessment

In consultation with management and Compensia, our compensation and talent management committee’s independent compensation consultant, in March 2021, our compensation and talent management committee assessed our compensation plans, policies and practices for named executive officers and other employees and concluded that they do not create risks that are reasonably likely to have a material adverse effect on us. This risk assessment included, among other things, a review of our cash and equity incentive-based compensation plans to ensure that they are aligned with our performance goals and overall target total direct compensation to ensure an appropriate balance between fixed and variable pay components. Our compensation and talent management committee conducts this assessment annually.
Compensation and Talent Management Committee Report
Our compensation and talent management committee has reviewed and discussed the section titled “Compensation Discussion and Analysis” with management. Based on such review and discussion, our compensation and talent management committee has recommended to the board of directors that the section titled “Compensation Discussion and Analysis” be included in this Amendment No.1 to our Annual Report on Form
10-K
for the fiscal year ended December 31, 2021.
Respectfully submitted by the members of our compensation and talent management committee of the board of directors:

Summary Compensation Table
Risk -free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the stock-based awards; and
Expected dividend. The expected dividend is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock.
(n)Income Taxes
The following table provides information regardingCompany accounts for income taxes in accordance with authoritative guidance which requires the use of the asset and liability approach. Deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss and tax credit carry-forwards. Deferred tax amounts are determined by using the enacted tax rates expected to be in effect when the temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance reduces the deferred tax assets to the amount that is more likely than not to be realized.
The Company recognizes the effect of uncertain income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is more than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
The Company records interest and penalties related to uncertain tax positions in the provision for income taxes in the consolidated statements of operations.
(o)Foreign Currency
The functional currency of the Company's foreign subsidiaries is primarily the U.S. dollar. Accordingly, the subsidiaries remeasure monetary assets and liabilities at period-end exchange rates, while non-monetary items are remeasured at historical rates. Revenue and expense accounts are remeasured at the average exchange rate in effect during the month in which the transactions occur. Remeasurement adjustments are recognized in the consolidated statements of operations as other income (expense), net, in the year of occurrence. Foreign currency transaction gains and losses are included in other income (expenses), net, in the accompanying consolidated statements of operations.
For those entities where the functional currency is a foreign currency, adjustments resulting from translating the financial statements into U.S. dollars are recorded as a component of accumulated other comprehensive income (loss) as part of the total compensation,stockholders' equity. Monetary assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenue and expenses are translated at the weighted average exchange rates in effect during the month in which the transactions occur. Equity transactions are translated using historical exchange rates.
(p)Comprehensive Income (Loss)
Comprehensive income (loss) refers to net loss and other revenue, expenses, gains and losses that, under U.S. GAAP, are recorded as an element of stockholders' equity but are excluded from the calculation of net loss.
(q)Net Loss Per Share Attributable to Common Stockholders
The Company calculates its basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for services rendered in all capacities,companies with participating securities. The Company has 100,000,000 shares of preferred stock that was paid toauthorized but never issued or earned by our named executive officers duringoutstanding.
Class A common stock was the fiscal years ended December 31, 2019, 2020 and 2021.

Potential Payments Upon Termination or Change in Control
Executive Severance Plans
We maintain three separate executive severance plans (i.e., the Chief Executive Officer Severance Plan and Key Executive Severance Plan, collectively the “
Executive Severance Plans
,” and the VP Severance Plan). We do not provide for any severance or change in control payments or benefits in our named executive officers’ employment offer letters (except for limited vesting acceleration provisions in our Chief Revenue Officer’s promotion letter). Each of our named executive officers, including our Chief Executive Officer and Chief Operating Officer and Principal Financial Officer, is a participant in the applicable Executive Severance Plan, as further described below. The Executive Severance Plans provide for certain payments and benefits in the event of a termination of employment, including an involuntary termination of employment in connection with a change in control of the Company.
33

Table of Contents
Our Executive Severance Plans provide that upon a termination of employment by us for any reason other than for “
cause
” (as defined in the applicable Executive Severance Plan), death or disability outside of the change in control period (i.e., the period beginning three months prior to and ending 12 months after, a “
change in control
,” as defined in the applicable Executive Severance Plan), an eligible participant will be entitled to receive, subject to the execution and delivery of an effective release of claims in our favor, (i) a lump sum cash payment equal to nine months of base salary for our Chief Executive Officer, and six months of base salary for our other named executive officers, and (ii) a monthly cash payment for up to nine months for our Chief Executive Officer and up to six months for our other named executive officers equal to the monthly contribution we would have made to provide health insurance to the named executive officer if he or she had remained employed by us. Pursuant to the CEO Severance Plan, our Chief Executive Officer is also entitled to such benefits upon a resignation of employment for “
good reason
” (as defined in the CEO Severance Plan) outside of the change in control period. In addition, upon a (i) termination of employment by us other than due to cause, death or disability or (ii) a resignation of employment for “
good reason
”, in each case, outside of the change in control period, our Chief Executive Officer will be entitled to 12 months of acceleration of vesting for outstanding and unvested time-based equity awards.
The Executive Severance Plans also provide that upon a (i) termination of employment by us other than due to cause, death or disability or (ii) a resignation of employment for “
good reason
” (as defined in the applicable Executive Severance Plan), in each case, within the change in control period, an eligible participant will be entitled to receive, in lieu of the payments and benefits above and subject to the execution and delivery of an effective release of claims in our favor, (1) a lump sum cash payment equal to 18 months of base salary for our Chief Executive Officer and 12 months of base salary for our other named executive officers, (2) a monthly cash payment for up to 18 months for our Chief Executive Officer and up to 12 months for our other named executive officers equal to the monthly contribution we would have made to provide health insurance to the named executive officer if he or she had remained employed by us, and (3) full accelerated vesting of all outstanding and unvested equity awards held by our named executive officers; provided, that the performance conditions applicable to any stock-based awards subject to performance conditions will be deemed satisfied at the target level specified in the terms of the applicable award agreement.
The payments and benefits provided under the Executive Severance Plans in connection with a change in control may not be eligible for a federal income tax deduction by us pursuant to Section 280G of the Code. These payments and benefits may also subject an eligible participant, including the named executive officers, to an excise tax under Section 4999 of the Code. If the payments or benefits payable to an eligible participant in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net
after-tax
benefit to him or her.
Other Change in Control and Severance Arrangements
The following table presents information concerning estimated payments and benefits that would be provided in the circumstances described above for each of the named executive officers who were serving as named executive officers as of the end of the fiscal year ending December 31, 2021. Messrs. Hu and Chew resigned as of October 27, 2021 and May 17, 2021, respectively, and received no compensation in connection with their terminations.

Table of Contents
The payments and benefits set forth below are estimated assuming that the termination or change in control event occurred on the last business day of our fiscal year ending December 31, 2021 using the closing market price of our stock on that date. Actual payments and benefits could be different if such events were to occur on any other date or at any other price or if any other assumptions are used to estimate potential payments and benefits.

CEO Pay Ratio
Pursuant to SEC rules, we are required to provide information regarding the relationship between the annual total compensation of our Chief Executive Officer, and the median of the annual total compensation of all of our employees (other than our Chief Executive Officer) for the year ended December 31, 2021:
the annual total compensation of our median employee was $166,789; and
35

Table of Contents
the annual total compensation of our Chief Executive Officer was $14,625,745, as reported in the “Total Compensation” column in the “Summary Compensation Table” included in this Amendment.
Based on this information, for 2021, the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all our employees was 88:1. We believe this ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation
S-K
under the Exchange Act.
As a result of the increase in our number of employees from 4,629 employees as of December 31, 2020 to 7,867 employees as of December 31, 2021, we elected to identify a new median employee as of December 31, 2021. In doing so, we used the same methodology we employed to identify the median employee as of December 31, 2020. Specifically, as permitted by SEC rules, we reviewed total direct compensation based on our consistently applied compensation measure, which we calculated as actual salary paid to our employees for 2021, actual sales commission earned by our employees in 2021, and the grant date fair value of equity awards granted to our employees in 2021.
We used December 31, 2021 to determine our employee population. In determining this population, we included all worldwide full-time and part-time employees other than our Chief Executive Officer. We excluded contractors, workers employed through a third-party provider, individuals with zero pay in 2021, and 380 employees of ValueFirst Digital Media Private Limited, which was acquired by us in 2021, from our employee population. For employees paid in other than U.S. dollars, we converted their compensation to U.S. dollars using the exchange rates used by us for various purposes in effect on December 31, 2021 and did not make any
cost-of-living
adjustments to such compensation. We did not annualize total direct compensation for employees employed by us for less than the full fiscal year. Using our consistently applied compensation measure, we identified a median employee who is a full-time U.S.-based salaried employee.
Once we selected the individual who represented the median employee, we then calculated the annual total compensation for this employee using the same methodology we used for our named executive officers in our 2021 Summary Compensation Table to yield the median annual total compensation disclosed above.
The SEC’s rules for identifying the median employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. We believe our methodologies are reasonable and best reflect how we view these metrics. However, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.
Non-Employee
Director Compensation
Non-Employee
Director Compensation Policy
We have adopted a compensation policy for our
non-employee
directors (as amended and restated from time to time, the “
Non-Employee
Director Compensation Policy
”) to attract, retain and award these individuals and align their long-term interests with those of the Company and our stockholders. Our
non-employee
directors are paid in the form of restricted stock units (“
RSUs
”) only and do not receive cash compensation. Employee directors receive no additional compensation for their service as a director.
Decisions regarding the
Non-Employee
Director Compensation Policy are approved by our board of directors based on recommendations from our compensation and talent management committee. Our compensation and talent management committee conducts an annual evaluation of the design and
36

Table of Contents
competitiveness of our
Non-Employee
Director Compensation Policy in light of best practices, market trends and a competitive market analysis of data for the Company’s compensation peer group prepared by its compensation consultant, and makes appropriate recommendations to our board of directors with respect to the compensation of our
non-employee
directors.
During 2021, our compensation and talent management committee engaged Compensia, Inc. (“
Compensia
”), a national compensation consulting firm, as its compensation consultant to advise on, among other things,
non-employee
director compensation matters. In doing so, our compensation and talent management committee reviewed and considered a peer group compensation data analysis prepared by Compensia. Our compensation and talent management committee targeted
non-employee
director compensation, to consist solely of RSUs, to the 50
th
percentile relative to our peers. In May 2021, upon the recommendation of the compensation and talent management committee, our board of directors approved the following changes to our
Non-Employee
Director Compensation Policy for fiscal 2021: (i) increase the annual equity retainer for the lead independent director from $20,000 to $23,000; (ii) increase the annual equity retainer for members of the audit committee (other than the chairperson) from $11,000 to $13,000; (iii) increase the annual equity retainer for the audit committee chairperson from $22,000 to $26,000; (iv) increase the annual equity retainer for members of the compensation and talent management committee (other than the chairperson) from $9,000 to $10,000; (v) increase the annual equity retainer for the compensation and talent management committee chairperson from $18,000 to $20,000; (vi) increase the annual equity retainer for members of the nominating and corporate governance committee (other than the chairperson) from $5,000 to $6,000 (vii) increase the annual equity retainer for the nominating and corporate governance committee chairperson from $10,000 to $12,000; (viii) increase the Initial Equity Grant (as defined below) from $440,000 to $575,000; and (ix) pay all annual retainers for board membership, lead independent director and committee membership in the form of RSUs in lieu of cash compensation.
For purposes of the amounts described in this section, the values are calculated as set forth in the
Non-Employee
Director Compensation Policy. For the aggregate grant date fair value of the RSUs awarded to the
non-employee
directors in the fiscal year ended December 31, 2021, calculated in accordance with FASB ASC Topic 718, please see “2021
Non-Employee
Director Compensation Table” below.

Annual Equity Grants
In addition, on the date of our annual meeting of stockholders, each
non-employee
director who continued as a member of our board of directors following such annual meeting of stockholders received a grant of RSUs having a value of $250,000 (the “
Annual Equity Grant
”).
During fiscal year 2021, the number of RSUs for the Annual Equity Grant was determined by dividing the applicable values by the average closing market price on The New York Stock Exchange (or such other market on which the Company’s Class A common stock is then principally listed)entitled to one vote per share.

On June 28, 2023, each outstanding share of the Company’s Class B common stock automatically converted (the “Conversion”) into one share of the Company’s Class A common stock pursuant to the terms of the Company’s certificate of incorporation. In addition, upon the Conversion, all outstanding stock options that were exercisable for shares of Class B common stock prior to the Conversion became exercisable for shares of Class A common stock. The Company filed a Certificate of Retirement with the Secretary of State of the State of Delaware effecting the retirement of all of the shares of its Class B common stock that were issued but not outstanding following the Conversion.
The Company also has dilutive securities, such as potential or restricted common shares or common stock equivalents, that were excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect was antidilutive in all periods presented. These securities are presented in Note 20 to these consolidated financial statements.
(r)Cash and Cash Equivalents
The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents may consist of cash deposited into money market funds, reverse repurchase agreements and commercial paper. All credit and debit card transactions that process as of the last day of each month and settle within the first few days of the subsequent month are also classified as cash and cash equivalents as of the end of the month in which they were processed.
(s)Accounts Receivable and Allowance for Doubtful Accounts
Accounts receivable are recorded net of the allowance for doubtful accounts. The allowance for doubtful accounts is estimated based on the Company's assessment of its ability to collect on customer accounts receivable. The Company regularly reviews the allowance by considering certain factors such as historical experience, credit quality, age of accounts receivable balances and other known conditions that may affect a customer's ability to pay. In cases where the Company is aware of circumstances that may impair a specific customer's ability to meet their financial obligations, a specific allowance is recorded against amounts due from the customer which reduces the net recognized receivable to the amount the Company reasonably believes will be collected. The Company writes-off accounts receivable against the allowance when a determination is made that the balance is uncollectible and collection of the receivable is no longer being actively pursued. As of December 31, 2023 and 2022, the allowance for doubtful accounts was $42.0 million and $27.0 million, respectively, and is recorded in accounts receivable, net, in the accompanying consolidated balance sheets.
(t)Costs Related to Public Offerings
Costs related to public offerings, which consist of direct incremental legal, printing and accounting fees are deferred until the offering is completed. Upon completion of the offering, these costs are offset against the offering proceeds within the consolidated statements of stockholders' equity.
(u)Property and Equipment
Property and equipment, both owned and under finance leases, is stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the trailing
30-day
period ending five business days before the effective dateestimated useful life of the grant.related asset. Maintenance and repairs are expensed as incurred.

Furniture and fixtures5 years
Software3 years
Assets under financing leaseShorter of 5 years or the remaining lease term
84


(v)Leases
The Company determines if an arrangement is or contains a lease at contract inception. The Company presents the operating leases in four quarterly installmentslong-term assets and current and long-term liabilities. Finance lease assets are included in property and equipment, net, and finance lease liabilities are presented in current and long-term liabilities in the accompanying consolidated balance sheets.
Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are measured and recognized at the lease commencement date based on the present value of the remaining lease payments over the courselease term. As the Company’s leases do not generally provide an implicit rate, the Company uses its incremental borrowing rate based on the information available on the commencement date to determine the present value of lease payments. The Company’s lease agreements may have lease and non-lease components, which the Company accounts for as a single lease component. When estimating the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain such options will be exercised. Operating lease costs are recognized in operating expenses in the accompanying consolidated statements of operations on a straight-line basis over the lease term and variable payments are recognized in the period they are incurred. The Company’s lease agreements do not contain any residual value guarantees. Leases with an initial term of 12 months or less are not recorded on the balance sheet.
Within the consolidated statements of cash flows, the Company presents the lease payments made on the operating leases as cash flows from operations and principal payments made on the finance leases as part of financing activities.
(w)Equity Method Investments
Equity investment holdings in which the Company does not have a controlling financial interest but can exercise significant influence over the investee are accounted for under the equity method. Equity method investments are originally recorded at cost and are increased or reduced in subsequent periods to reflect the Company’s proportionate share of the investee’s net earnings or losses and other comprehensive income or losses, as those occur. The Company records the investee losses on a three-month lag and up to the carrying amount of the investment. Investments are also increased or decreased by contributions made to and distributions received from the investee, basis difference amortization and other-than-temporary impairments, if any. All costs directly associated with the acquisition of the investment are included in the carrying amount of the investment. Profits or losses related to intra-entity sales are eliminated until realized by the Company or the investee.
The Company determines the difference between its purchase price and its proportionate share of the net assets of the investee, which results in an excess basis in the investment. This excess basis is allocated to the identifiable assets and liabilities of the investee utilizing purchase accounting principles and is used to calculate the amortization of basis differences every reporting period. Basis differences related to intangible assets with determinable economic lives and liabilities are generally amortized on a straight-line basis over the useful lives of the associated assets and the expected term for the liabilities. Basis differences related to intangible assets without determinable economic lives are not amortized.
Equity method goodwill is not amortized or tested for impairment. Instead, the Company evaluates its equity method investments for impairment whenever events or changes in circumstance indicate that the carrying amounts of such investments may be in excess of their fair value. When such indicators exist, the other-than-temporary impairment model is utilized, which considers the severity and duration of a decline in fair value below book value and the Company’s ability and intent to hold the investment for a sufficient period of time to allow for recovery. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in the period of such determination.
(x)Segment Information
The Company determines its operating and reportable segments in accordance with Accounting Standards Codification 280 Segment Reporting (“ASC 280”), which requires financial information to be reported based on how the chief operating decision maker (“CODM”), who is the Company's Chief Executive Officer (“CEO”), reviews and manages the business, and establishes criteria for aggregating operating segments into reportable segments. Prior to 2023, the Company had one operating and reportable segment. As a result of the restructuring activities in 2023, as described in Note 8, the Company operated in and reported its results in two reportable segments.
85


(y)Business Combinations
The Company records identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill is measured as the excess of the consideration transferred over the fair value of the net assets acquired on the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed, these estimates are inherently uncertain and subject to refinement. The authoritative guidance allows a measurement period of up to one year that commences onfrom the date of eachacquisition to make adjustments to the preliminary allocation of the purchase price. As a result, during the measurement period the Company may record adjustments to the fair values of assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that it identifies adjustments to the preliminary purchase price allocation. Upon conclusion of the measurement period or final determination of the values of the assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the consolidated statements of operations.
(z)Goodwill
Goodwill represents the excess of the aggregate purchase price over the fair value of net identifiable assets acquired in a business combination. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Goodwill is allocated within the operating segments of the Company to the reporting units. Prior to 2023, the Company had one reporting unit. During 2023, as a result of restructuring activities described in Note 8, the Company then had multiple reporting units. The Company reassigns its assets and liabilities to the reporting units based on which reporting units’ operations the assets and liabilities were employed in or were related to. Goodwill is reassigned using a relative fair value allocation approach.
The Company has selected November 30 as the date to perform its annual meetinggoodwill impairment test. The goodwill impairment test is performed on a reporting unit level. In the valuation of stockholders, with such grantsgoodwill, management must make assumptions regarding estimated future cash flows to be made on each September 15, December 15, March 15,derived from the respective reporting unit. If these estimates or their related assumptions change in the future, the Company may be required to record an impairment of goodwill. The Company has the option to first perform a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. However, the Company may elect to bypass the qualitative assessment and the earlier of (i) June 15 or (ii) the day that is immediately priorproceed directly to the next subsequent annual meeting of stockholders (each such date, a “
Quarterly Date
,” and each such grant, a “
Quarterly Grant
”).quantitative impairment tests. The impairment test involves comparing the fair value of the reporting unit to its carrying value, including goodwill. A goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value. The impairment is limited to the carrying amount of goodwill.
(aa)Intangible Assets
Intangible assets recorded by the Company include the fair values of identifiable intangible assets acquired in business combinations and costs directly associated with securing legal registration of patents and trademarks and acquiring domain names.
Intangible assets with determinable economic lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful life of each Quarterly Grant shallasset on a straight-line basis. The Company determines the useful lives of identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, the Company's long-term strategy for using the asset, any laws or other local regulations which could impact the useful life of the asset and other economic factors, including competition and specific market conditions. Intangible assets without determinable economic lives are carried at cost, not amortized and reviewed for impairment at least annually.
86


The useful lives of the intangible assets are as follows:
Developed technology3 - 7 years
Customer relationships4 - 10 years
Supplier relationships5 years
Trade names5 years
Patents20 years
Telecommunication licensesIndefinite
TrademarksIndefinite
Domain namesIndefinite
(ab)Impairment of Long-Lived Assets
The Company evaluates its long-lived assets, including property, equipment and intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset or asset group. If such evaluation indicates that the carrying amount of the asset or the asset group is not recoverable, any impairment loss would be equal to the amount the carrying value exceeds the fair value. The impairment is allocated to the long-lived assets within the asset group on a pro-rata basis using the relative carrying amounts of the assets. Values of individual long-lived assets are not reduced in excess of their respective fair values.
In the valuation of an asset or an asset group, management must make assumptions regarding estimated future revenue and cash flows to be derived from the respective asset or asset group, discount rates used and other assumptions. If these estimates or their related assumptions change in the future, the Company may be required to record impairment of these assets.
(ac)Derivatives and Hedging
The Company is exposed to a wide variety of risks arising from its business operations and overall economic conditions. These risks include exposure to fluctuations in various foreign currencies against its functional currency and can impact the value of cash receipts and payments. The Company minimizes its exposure to these risks through management of its core business activities, specifically, the amounts, sources and duration of its assets and liabilities, and the use of derivative financial instruments. The Company uses foreign currency derivative forward contracts, and in the future may also use foreign currency option contacts.
Foreign currency derivative forward contracts involve fixing the exchange rate for delivery of a specified amount of foreign currency on a specified date. These agreements are typically cash settled in U.S. dollars for their fair value at or close to their settlement date. Foreign currency option contracts will require the Company to pay a premium for the right to sell a specified amount of foreign currency prior to the maturity date of the option. The Company does not enter into derivative financial instruments trading for speculative purposes.
Derivative instruments are carried at fair value and recorded as either an asset or a liability until they mature. Gains and losses resulting from changes in fair value of these instruments are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. For derivative instruments designated as cash flow hedges, gains or losses are initially recorded in accumulated other comprehensive income (loss) on the balance sheet, then reclassified into the statement of operations in the period in which the derivative instruments mature. These realized gains and losses are recorded within the same financial statement line item as the hedged transaction.
The Company’s foreign currency derivative contracts are classified within Level 2 of the fair value hierarchy because the valuation inputs are based on quoted prices and market observable data of similar instruments in active markets, such as currency spot and forward rates.
87


(ad)Share Repurchases
The Company elected to record the excess of the repurchase price over the par value of the portionrepurchased shares of the Annual Equity Retainer and Annual Equity Grants applicable to the period beginning on the day after the immediately preceding Quarterly Date and ending on the then-current Quarterly Date (the “
Quarterly Period
”), based on the board and committee roles held by the
non-employee
director during such Quarterly Period. Each Quarterly Grant shall be fully vested upon the date of grant.
Initial Equity Grants
Our
Non-Employee
Director Compensation Policy during fiscal year 2021 provided that, upon initial election to our board of directors, each
non-employee
director would be granted RSUs having a value of $575,000 (the “
Initial Equity Grant
”). The Initial Equity Grant vests in equal annual installments over three years, subject to continued service as a director through the applicable vesting dates; provided, however, that if a
non-employee
director is elected on a date other than at the annual meeting of stockholders,
one-third
(1/3rd) of such value shall be
pro-rated
by the amount of time between such election and the next annual meeting of stockholders and such
pro-rated
portion shall vest on the day prior to the next annual meeting of stockholders, with the other
two-thirds
(2/3rds) vesting annually over the following two years following such initial vesting date.
During fiscal year 2021, the number of RSUs for the Initial Equity Grant was determined by dividing the applicable value by the average closing market price on The New York Stock Exchange (or such other market on which the Company’sits Class A common stock in accumulated deficit, along with the associated transaction costs and excise taxes. Immediately upon repurchase, the shares are retired and returned to the status of unauthorized and unissued.
On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax.
(ae)Fair Value of Financial Instruments
The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:
Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.
Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.
A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
The Company applies fair value accounting for all financial instruments on a recurring basis. The Company's financial instruments, which include cash, restricted cash, cash equivalents, accounts receivable and accounts payable are recorded at their carrying amounts, which approximate their fair values due to their short-term nature. Marketable securities consist of U.S. treasury securities, non-U.S government securities, high credit quality corporate debt securities and commercial paper. All marketable securities are considered to be available-for-sale and recorded at their estimated fair values. Unrealized gains and losses for available-for-sale securities are recorded in other comprehensive loss. In valuing these items, the Company uses inputs and assumptions that market participants would use to determine their fair value, utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.
The fair values of the senior notes due 2029 and 2031 (“2029 Notes” and “2031 Notes,” respectively) are determined based on their respective closing prices on the last trading day of the reporting period and are classified as Level 2 in the fair value hierarchy.
The carrying value of the strategic investments, which consist of restricted equity securities of a publicly held company and equity securities of privately held companies, is determined under the measurement alternative on a non-recurring basis adjusting for observable changes in fair value. The Company does not have a controlling interest nor it can exercise significant influence over any of these entities.
The Company regularly reviews changes to the rating of its debt securities by rating agencies and monitors the surrounding economic conditions to assess the risk of expected credit losses. As of December 31, 2023, the risk of expected credit losses was not significant.
88


Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likely that the security will be sold before the recovery of its cost basis. Realized gains and losses and declines in value deemed to be other than temporary are determined based on the specific identification method and are reported in other expenses, net.
(af)Recently Issued Accounting Guidance, Not yet Adopted
In June 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2022-03, “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies and amends the guidance of measuring the fair value of equity securities subject to contractual restrictions that prohibit the sale of the equity securities. ASU 2022-03 is effective for interim and annual periods beginning after December 15, 2023, with early adoption permitted. The Company will adopt ASU 2022-03 in the first quarter of 2024 with no material impact to the Company’s consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which is intended to improve reportable segment disclosures. The ASU expands segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss. It also requires disclosure of the amount and description of the composition of other segment items and interim disclosures of a reportable segment's profit or loss and assets. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 with retrospective application required. Early adoption is permitted. The Company is evaluating the impact of the adoption of this guidance on its consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation and modifies other income tax related disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 and may be applied on a prospective basis. Early adoption is permitted. The Company is evaluating the impact of the adoption of this guidance on its consolidated financial statements.

Debt Securities
The aggregate fair value of corporate debt securities with unrealized losses is $1.5 billion as of December 31, 2023, of which $415.2 million have been in an unrealized loss position for more than 12 months and $1.1 billion have been in an unrealized loss position for less than 12 months. The aggregate fair value of corporate debt securities with unrealized losses was $2.7 billion as of December 31, 2022, of which $2.0 billion were in an unrealized loss position for more than 12 months and $620.5 million were in an unrealized loss position for less than 12 months. Unrealized losses related to other investments as of December 31, 2023 and 2022 were not significant.
The Company’s primary objective when investing excess cash is preservation of capital, hence the Company’s debt securities primarily consist of U.S. Treasury Securities, non-U.S government securities, high credit quality corporate debt securities and commercial paper. Because the Company views its debt securities as available to support current operations, it has classified all available for sale securities as short-term. As of December 31, 2023 and 2022, for all securities that were in
90


unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. In addition, as of December 31, 2023 and 2022, the Company anticipates that it will recover the entire amortized cost basis of such debt securities before maturity.
Interest earned on marketable securities was $77.7 million, $64.6 million and $55.7 million in the years ended December 31, 2023, 2022 and 2021, respectively. The interest is recorded as other income (expenses), net, in the accompanying consolidated statements of operations.

Equity Securities
The equity securities consist of shares of a publicly traded company that were received as consideration in a divestiture transaction described further in Note 5.
Strategic Investments
As of December 31, 2023 and 2022, the Company held strategic investments with an aggregate carrying value of $30.7 million and $76.9 million, respectively, recorded as other long-term assets in the accompanying consolidated balance sheets. The carrying value of these securities is determined under the measurement alternative on a non-recurring basis and adjusted for observable changes in fair value or impairment. In the year ended December 31, 2023, the Company remeasured to fair value one of its strategic investments acquired in 2021 due to an assessed impairment. The fair value measurement of the strategic investment is classified as Level 2 in the fair value hierarchy and the primary input used in the fair value measurement was the publicly available stock price of the issuer’s unrestricted security of the same class. The impairment loss of $46.2 million is recorded in other expenses, net, in the accompanying consolidated statement of operations for the year ended December 31, 2023. There were no other impairments or adjustments recorded in the three years ended December 31, 2023, 2022 and 2021, related to these securities.
Financial Liabilities
The Company’s financial liabilities that are measured at fair value on a recurring basis consist of foreign currency derivative liabilities and are classified as Level 2 financial instruments in the fair value hierarchy. As of December 31, 2023 and 2022, the aggregate fair value of these liabilities and the associated unrealized losses were not significant.
The Company’s financial liabilities that are not measured at fair value on a recurring basis are its 2029 Notes and its 2031 Notes. As of December 31, 2023, the fair value of the 2029 Notes and 2031 Notes were $462.4 million and $452.3 million, respectively. As of December 31, 2022, the fair value of the 2029 Notes and 2031 Notes were $410.9 million and $399.4 million, respectively.

6. Impairment
Operating right-of-use assets
In 2022, the Company announced its decision to become a remote-first company whereby employees would have the flexibility to work remotely on a permanent basis. As part of the new operating strategy, the Company permanently closed several of its offices in 2023 and 2022, which required the Company to reassess its operating right-of-use (“ROU”) assets and the associated leasehold improvements and property and equipment for impairment. The Company determined that the carrying amounts of these assets exceeded their respective fair values. The Company engaged a third‑party expert to assist with the valuation analysis. The Company regularly assesses recoverability of all impacted ROU assets and the related long-lived asset categories for indicators of impairment. In the years ended December 31, 2023 and 2022, the Company recorded $34.8 million and $97.7 million of impairment, respectively, related to its permanently closed offices. The impairment is recorded in the impairment of long-lived assets line item in the accompanying consolidated statements of operations for the years ended December 31, 2023 and 2022.

Intangible assets
In the fourth quarter of 2023, the Company identified a change in its Segment reportable segment’s performance which it deemed to be an indicator that the carrying amounts of certain long-lived assets within the segment may not be recoverable. The Company performed a recoverability assessment and a fair value measurement of the impacted asset group and concluded that the asset group was impaired. The Company engaged a third-party expert to assist with the valuation analysis. The impairment was allocated to the assets within the impacted asset group reducing the respective carrying amounts of the assets as of the December 1, 2023, measurement date, as follows:
Total Impairment Allocation

8. Reorganization and Segment Reporting
In February 2023, the Company announced a reorganization of its business into two business units, Twilio Communications and Twilio Data & Applications (the “Reorganization”). With the Reorganization, the Company changed the organizational structure of its business, including the way management operated the business. In the second quarter of 2023, the Company concluded that it had two operating and reportable segments: Twilio Communications (“Communications”) and Twilio Data & Applications (“Data & Applications”).
In the fourth quarter of 2023, the Company further reorganized its business by shifting certain components of the business between its operating segments. This reorganization did not impact the segment structure of the business. The impact on the reporting unit structure is described in Note 12.
After the reorganization, the Company’s Data & Applications segment consisted of its Segment and Engage products and, therefore, the reportable segment was renamed from Data & Applications to Twilio Segment (“Segment”).
Twilio Communications: The Communications segment consists of a variety of application programming interfaces (“APIs”) and software solutions to optimize communications between Twilio customers and their end users. The key products from which the segment derives its revenue are Messaging, Voice and Email.
Twilio Segment:The Segment segment consists of software products that enable businesses to achieve more effective customer engagement by providing the tools necessary for customers to build direct, personalized relationships with their end users. The key products from which the segment derives its revenue are Segment and Engage.

Discrete financial information reviewed by the CODM
In January 2024, the Company’s newly appointed CEO, who is also the CODM, began reviewing segment operating results using non-GAAP income from operations as the measure of segment profitability. Presented below is the discrete financial information by reportable segment for the years ended December 31, 2023, 2022, and 2021, that reflects management’s current view of the business for performance assessment and resource allocation decisions. Prior period amounts were reclassified to conform to the current period’s presentation. Asset information is not presented below since it is not reviewed by the CODM on a segment by segment basis. Revenue, costs of revenue and operating expenses are generally directly attributable to each segment. Certain costs of revenue and operating expenses are allocated based on methodologies that best reflect the patterns of consumption of these costs. Corporate costs consist of costs that support company-wide processes and are managed on the company-wide level, and include costs related to corporate governance and communication, global brand awareness, information security, and certain legal, finance and accounting expenses.

11. Equity Method Investment
In May 2022, the Company acquired 44.6% equity interests in Syniverse Corporation (“Syniverse”) for $750.0 million in cash. The Company determined that it does not have a controlling financial interest in Syniverse but does exercise significant influence and therefore, the investment was accounted for under the equity method. The Company estimated that on the investment closing date there was an excess investment basis of $530.7 million related to its proportionate share of the identifiable intangible assets and $41.3 million related to the associated deferred tax liability. The equity method goodwill was estimated at $623.8 million.
The Company engaged a third‑party expert to assist with the valuation analysis. The following table presents the estimated basis differences attributable to the identifiable intangible assets as of the date of investment and their respective useful lives:

12. Goodwill and Intangible Assets
Goodwill
The business reorganization activities described in Note 8 impacted the Company’s reporting unit structure and, as a result, in 2023 the Company had multiple reporting units. These changes required the Company to reallocate goodwill to its newly formed reporting units and test the goodwill for impairment on the reporting unit level immediately before and immediately after each reorganization. The Company engaged a third-party expert to assist in the valuation analysis. The Company concluded that its goodwill was not impaired immediately before and immediately after the reorganizations.

The Company estimates the fair value of its reporting units using a weighting of fair values derived from an income and a market approach. Estimating the fair value by these methods involves the use of various assumptions that the Company believes are reasonable under then principally listed)current circumstances. Under the income approach, the Company determines the fair value of a reporting unit based on the present value of estimated future cash flows using the cash flow projections prepared by management. The market approach estimates the fair value based on market multiples of revenue or adjusted EBITDA, as applicable, derived from comparable publicly traded companies with similar operating and investment characteristics as the reporting unit. While these assumptions reflect management’s best estimates of future performance at the time, these estimates are inherently complex and uncertain and the Company’s actual results could differ materially from these estimates.

The indenture governing the Notes (the “Indenture”) contains restrictive covenants limiting the Company’s ability and the ability of its subsidiaries to: (i) create liens on certain assets to secure debt; (ii) grant a subsidiary guarantee of certain debt without also providing a guarantee of the Notes; and (iii) consolidate or merge with or into, or sell or otherwise dispose of all or substantially all of its assets to another person. These covenants are subject to a number of limitations and exceptions. Certain of these covenants will not apply during any period in which the Notes are rated investment grade by either Moody’s Investors Service, Inc. or Standard & Poor’s Ratings Services.
As of December 31, 2023, the Company was in compliance with all of its covenants under the Indenture.

17. Commitments and Contingencies

(a)Lease and Other Commitments
The Company entered into various non-cancelable operating lease agreements for its facilities. Refer to Note 10 for additional detail on the Company's operating lease commitments.
103


Additionally, the Company has contractual commitments with its cloud infrastructure providers, network service providers and other vendors that are noncancellable and expire within one to three years. In the year ended December 31, 2023, the Company entered into several such agreements with terms of up to three years for a total purchase commitment of $103.8 million. Future minimum payments under these noncancellable purchase commitments are summarized in the table below. Unrecognized tax benefits are not included in these amounts because any amounts expected to be settled in cash are not significant:

2025241,056

(b)Legal Matters
From time to time, the Company may be subject to legal actions, claims, and government investigations or inquiries arising in the ordinary course of business. These matters may include, but are not limited to, matters involving privacy, data protection, data security, intellectual property, competition, telecommunications, consumer protection, taxation, securities, employment, and contractual rights. While the Company currently believes that the final outcomes of these matters will not have a material adverse effect on its business, the results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.
The Company accrues for contingencies when the Company believes that a loss is probable and that it can reasonably estimate the amount of any such loss. To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred and the amount of such additional loss would be material, the Company will either disclose the estimated additional loss or state that such an estimate cannot be made. Significant judgment is required to determine the probability of a loss and to estimate the amount of any probable loss.
Legal fees and other costs related to litigation and other legal proceedings are expensed as incurred and are included in general and administrative expenses in the accompanying consolidated statements of operations.
In 2020, the City and County of San Francisco (“San Francisco”) assessed the Company for additional Telephone Users Tax (“TUT”) and Access Line Tax on certain of the Company’s services for the years 2009 through 2018. The assessments totaled $38.8 million, including interest and penalties. The Company paid the assessments under protest in the third quarter of 2020.
On May 27, 2021, the Company filed a lawsuit against San Francisco in San Francisco Superior Court challenging the assessments. The parties agreed to a settlement agreement that was approved by San Francisco’s Board of Supervisors and Mayor on November 7, 2023 and November 9, 2023, respectively, pursuant to which San Francisco paid the Company $18.0 million in November 2023 in settlement of the Company’s claims. The related impacts to the consolidated balance sheet as of December 31, 2023 and statement of operations for the year ended December 31, 2023 were not significant.
(c)Indemnification Agreements
In the ordinary course of business and in connection with its financing and business combination transactions, the Company enters into contractual arrangements under which it agrees to provide indemnification of varying scope and terms to business partners, customers and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, intellectual property infringement claims made by third parties and other liabilities relating to or arising from the Company’s products or its acts or omissions.

The Company has also signed indemnification agreements with all of its board members and executive officers and certain employees that may require the Company to indemnify them for certain events in connection with their services to the Company or its direct or indirect subsidiaries.
104


As of December 31, 2023 and 2022, no amounts were accrued related to any outstanding indemnification agreements.
(d)Other Taxes
The Company conducts operations in many tax jurisdictions within and outside the United States. In many of these jurisdictions, non-income-based taxes, such as sales, use, telecommunications and other local taxes are assessed on the Company’s operations. The Company carries reserves for certain of its non-income-based tax exposures in certain jurisdictions when it is both probable that a liability was incurred and the amount of the exposure can be reasonably estimated. These reserves are based on estimates which include several key assumptions including, but not limited to, the taxability of the Company’s services, the jurisdictions in which its management believes it had nexus and the sourcing of revenues to those jurisdictions.
The Company continues to remain in discussions with certain jurisdictions regarding its prior sales and other taxes that it may owe. In the event any of these jurisdictions disagree with management’s assumptions and analysis, the assessment of the Company’s tax exposure could differ materially from management’s current estimates.
As of December 31, 2023, the liabilities recorded for the non-income-based taxes were $18.0 million for domestic jurisdictions and $22.2 million for jurisdictions outside of the United States. As of December 31, 2022, these liabilities were $29.1 million and $20.6 million, respectively.

Share Repurchase Program

Repurchases under this program can be made through open market, private transactions or other means, in compliance with applicable federal securities laws, and could include repurchases pursuant to the Rule 10b5-1 trading plans. The Company has discretion in determining the conditions under which shares may be repurchased from time to time. The program expires on December 31, 2024.
During the year ended December 31, 2023, the Company repurchased 11.3 million shares of its Class A common stock for an aggregate purchase price of $672.1 million. As of December 31, 2023, approximately $327.9 million of the originally authorized amount remained available for future repurchases.

The Company received total proceeds of $1.8 billion, net of underwriting discounts and offering expenses paid by the Company.
19. Stock-Based Compensation 
2008 Stock Option Plan
In connection with the Company’s initial public offering on June 22, 2016, the 2008 Stock Option Plan, as amended and restated (the “2008 Plan”), was terminated and, accordingly, no shares were available for issuance after the termination. As of December 31, 2023 and 2022, all remaining outstanding stock options granted under the 2008 Plan were vested and exercisable and continue to be governed by the provisions of this plan.
2016 Stock Option Plan
The Company’s 2016 Stock Option and Incentive Plan (the “2016 Plan”) became effective on June 21, 2016. The 2016 Plan provides for the grant of ISOs, NSOs, restricted stock, RSUs, stock appreciation rights, unrestricted stock awards, performance share awards, dividend equivalent rights and cash-based awards to employees, directors and consultants of the Company. A total of 11,500,000 shares of the Company’s Class A common stock over the trailing
30-day
period ending five business days before the effective date of the grant.
Awards granted under our
Non-Employee
Director Compensation Policy are subject to full accelerated vesting upon a “sale event,” as defined in our 2016 Stock Option and Incentive Plan (as amended and restated, the “
2016 Plan
”).
Our
Non-Employee
Director Compensation Policy also provides that, pursuant to the 2016 Plan, the aggregate amount of compensation, including both equity compensation and cash compensation, paid to any
non-employee
director in a calendar year will not exceed $750,000 (or such other limit as may be set forth in the 2016 Plan or any similar provision of a successor plan).
We also reimburse all reasonable
out-of-pocket
expenses incurred by our
non-employee
directorswere initially reserved for their attendance at meetings of our board of directors or any committee thereof.
Changes to
Non-Employee
Director Compensation effective for Fiscal 2022
Following a review with Compensia of peer company board compensation trends in March 2022, our compensation and talent management committee recommended, and our board of directors approved, the
38

Table of Contents
following changes to our
non-employee
director compensation effective fiscal 2022, targeting
non-employee
director compensation to the 50
th
percentile relative to our peers: (i) increase the annual equity retainer for the lead independent director from $23,000 to $30,000 and (ii) increase the annual equity retainer for all
non-employee
members of the board of directors from $40,000 to $45,000.
Non-Employee
Directors’ Deferred Compensation Program
In July 2017, we implemented a
Non-Employee
Directors’ Deferred Compensation Program to offer our
non-employee
directors the ability to defer the receipt of any RSUs granted to them from Initial Grants or Annual Grantsissuance under the 2016 Plan. In advanceThese available shares automatically increase each January 1, beginning on January 1, 2017, by 5% of an award of RSUs and in compliance with the program’s requirements, a
non-employee
director may elect to defer the receipt of all of his or her RSUs until the earliest of (i) 90 days after such
non-employee
director ceases to serve as a member of our board of directors; (ii) the consummation of a “sale event”; or (iii) 90 days after the
non-employee
director’s death (such earliest date, the “
Payment Event
”). Upon the vesting of the RSUs, any amounts that would otherwise have been paid in shares of Company common stock will be converted into deferred stock units (“
DSUs
”) on a
one-to-one
basis and credited to the
non-employee
director’s deferral account. The DSUs will be paid in shares of Company Class A common stock on a
one-to-one
basis in a single lump sum (and will cease to be held in the
non-employee
director’s deferred account) as soon as practicable following the Payment Event.
Death Equity Acceleration Policy
See “Executive Compensation—Other Compensation Policies and Practices—Death Equity Acceleration Policy” for a discussion of the treatment of equity awards upon the termination due to death of an employee’s or
non-employee
director’s employment or other service relationship with the Company or any of its subsidiaries.
Stock Ownership Policy
In April 2018, we adopted a stock ownership policy for our
non-employee
directors, which was amended and restated in September 2020 and March 2022. Our stock ownership policy, as amended, requires our
non-employee
directors to acquire and hold a number of shares of ourthe Company’s common stock equal in value to five times (increased from four times in March 2022) the director’s annual retainer for regular service on the board of directors. We only count directly and beneficially owned shares, including shares purchased through our Company’s 2016 Employee Stock Purchase Plan (as amended and restated, the “
ESPP
”) or Section 401(k) plan, if applicable, and shares underlying vested RSUs that are held or deferred. We do not count shares underlying vested but unexercised
in-the-money
stock options. Each
non-employee
director has five years from the later of his or her initial election to the board of directors or from the effective date of the policy to attain the required ownership level.

(3) 
As of December 31, 2021, a total of 24,650,104 shares of our Class A common stock were reserved for issuance pursuant to the 2016 Plan. This number includes shares reserved and available for issuance under the SendGrid 2009 Plan, the SendGrid 2012 Plan and the SendGrid 2017 Plan that we assumed, which were approved by the stockholders of SendGrid, but not by a separate vote of our stockholders; such shares became available for issuance under our 2016 Plan, but awards using such shares may not be granted to individuals who were employed, immediately prior to the acquisition, by us or our subsidiaries. This number excludes the 9,023,405 shares that were added to the 2016 Plan as a result of the automatic annual increase on January 1, 2022. The 2016 Plan provides that the number of shares reserved and available for issuance under the 2016 Plan will automatically increase each January 1, beginning on January 1, 2017, by 5% of the outstanding number of shares of our Class A and Class B common stock on the immediately preceding December 31 or such lesser number of shares as determined by our compensation and talent management committee. This number will be subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. The shares of Class A and Class B common stock underlying any awards that are forfeited, canceled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without the issuance of stock, expire or are otherwise terminated, other than by exercise, under the 2016 Plan and the 2008 Plan will be added back to the

shares of Class A common stock available for issuance under the 2016 Plan (provided, that any such shares of Class B common stock will first be converted into shares of Class A common stock). The Company no longer makes grants under the 2008 Plan. As of December 31, 2021, a total of 6,382,830 shares of our Class A common stock were available for future issuance pursuant to the ESPP, which number includes shares subject to purchase during the current purchase period, which commenced on November 16, 2021 (the exact number of which will not be known until the purchase date on May 13, 2022) but excludes the 1,800,000 shares that were added to the ESPP as a result of the automatic annual increase on January 1, 2022. Subject to the number of shares remaining in the share reserve, the maximum number of shares purchasable by any participant on any one purchase date for any purchase period, including the current purchase period may not exceed 5,000 shares. The ESPP provides that the number of shares reserved and available for issuance under the ESPP will automatically increase each January 1, beginning on January 1, 2017, by the lesser of 1,800,000 shares of our Class A common stock, 1% of the outstanding number of shares of our Class A and Class B common stock on the immediately preceding December 31 or such lesser number of shares as determined by our compensation and talent management committee.

Certain Relationships and Related Party Transactions, and Director Independence
Transactions with Related Persons
In addition to the compensation arrangements discussed in the section titled “Executive Compensation,” including employment, termination of employment and change in control arrangements, the following is a description of each transaction since the beginning of our last fiscal year, and each currently proposed transaction in which:
we have been or are to be a participant;
the amount involved exceeded or exceeds $120,000; and
any of our directors, executive officers, or holders of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.
Investors’ Rights Agreement
We are party to an investors’ rights agreement which provides, among other things, that certain holders of our capital stock have the right to demand that we file a registration statement or request that their shares of our capital stock be covered by a registration statement that we are otherwise filing. The parties to the investors’ rights agreement include entities affiliated with Jeff Lawson, our Chief Executive Officer and current director, an entity affiliated with Jeff Epstein, our current director, Evan Cooke, a former director, and Amazon.com NV Investment Holdings LLC and John Wolthuis, holders of more than 5% of our Class B common stock.
Sublease with Numenta
In the second quarter of fiscal year 2021, we entered into a sublease with Numenta, Inc. (“
Numenta
”), whereby we subleased 2,420 square feet of our unoccupied Redwood City office space to Numenta. Donna Dubinsky, a member of our board of directors, serves as the Chief Executive Officer and a director of Numenta. The sublease was entered into on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and at market rates. The term of the sublease is for 12 months commencing on August 1, 2021, with Numenta having the option to renew for two
12-month
extension periods. The rent was initially set at $18,225 per month, and if Numenta opts to renew the sublease, the rent for the first and second
12-month
extension periods includes set increases at $18,771.75 per month and $19,334.90 per month, respectively. If such options to renew are exercised by Numenta, the aggregate payments expected to be made under the sublease over the 36 month period is approximately $675,979.80, which is in compliance with the NYSE and LTSE director independence standards and does not exceed the greater of $1 million or 2% of Numenta’s consolidated gross revenues. In January 2022, Numenta timely notified us of its intention to exercise the option to renew the sublease for the first additional
12-month
period. Accordingly, the rent will increase to $18,771.75 per month effective August 1, 2022.

Other Transactions
We have granted stock options and RSUs to our named executive officers and certain of our directors. See the section titled “Executive Compensation—Individual Compensation Arrangements—Long-Term Incentive Compensation”, “Executive Compensation—Outstanding Equity Awards at Fiscal
Year-End
Table” and “Board of Directors and Corporate
Governance—Non-Employee
Director Compensation” for a description of these stock options and RSUs.
We have entered into severance and change in control arrangements with certain of our executive officers pursuant to employment offer letters and/or our severance plan that, among other things, provides for certain severance and change in control payments and benefits. See the sections titled “Executive Compensation—Post-Employment Compensation Arrangements” and “Executive Compensation—Potential Payments Upon Termination or Change in Control.”
Other than as described above under this section titled “Certain Relationships and Related Party Transactions,” since January 1, 2021, we have not entered into any transactions, nor are there any currently proposed transactions, between us and a related party where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material interest. We believe the terms of the transactions described above were comparable to terms we could have obtained in
arm’s-length
dealings with unrelated third parties.
Indemnification of Officers and Directors
Our amended and restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:
any breach of their duty of loyalty to our Company or our stockholders;
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or
any transaction from which they derived an improper personal benefit.
Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.
In addition, our second amended and restated bylaws provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. Our second amended and restated bylaws provide that we may indemnify our employees and agents to the extent not prohibited by the Delaware General Corporation Law or other applicable law. Our second amended and restated bylaws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to limited exceptions.
Further, we have entered into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the Delaware
46

Table of Contents
General Corporation Law. These indemnification agreements require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.
The limitation of liability and indemnification provisions that are included in our amended and restated certificate of incorporation, second amended and restated bylaws and in indemnification agreements that we have entered into with our directors and executive officers may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions.
We have obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to our directors and executive officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or executive officer, including claims relating to public securities matters, and to us with respect to payments that may be made by us to these directors and executive officers pursuant to our indemnification obligations or otherwise as a matter of law.
Certain of our
non-employee
directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of our board of directors.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling our Company pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
Policies and Procedures for Related Party Transactions
As set forth in our audit committee charter, our audit committee has the primary responsibility for reviewing and approving or disapproving “
related party transactions
,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. Our policy regarding transactions between us and related persons provides that a related person is defined as a director, executive officer, nominee for director or greater than 5% beneficial owner of our Class A and Class B common stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the capitalCompany’s compensation committee. On January 1, 2023 and 2022, the shares available for grant under the 2016 Plan were automatically increased by 9,298,785 shares and 9,023,405 shares, respectively.

Zipwhip 2008 Stock Plan and 2018 Equity Incentive Plan
In connection with its acquisition of Zipwhip, the Company assumed and replaced all stock options and restricted stock units of the continuing employees issued under Zipwhip’s Amended and Restated 2008 Stock Plan and 2018 Equity Incentive Plan (“Zipwhip Plans”) that were unvested and outstanding on the acquisition date. The assumed equity awards continue to vest and are governed by the provisions of the Zipwhip Plans.
Under all plans, stock options generally expire 10 years from the date of grant and vest over periods determined by the board of directors. The vesting period for stock options and restricted stock units is generally four years from the date of grant. For existing employees and, effective in 2022, for new-hires the stock options and restricted stock units vest in equal monthly and quarterly installments, respectively, over the service period.
2016 Employee Stock Purchase Plan
The Company’s 2016 ESPP was effective on June 21, 2016. A total of 2,400,000 shares of the Company’s Class A common stock were initially reserved for issuance under the 2016 ESPP. These available shares automatically increase each January 1, beginning on January 1, 2017, by the lesser of 1,800,000 shares of the Company's Class A common stock, 1% of the number of shares of the Company’s Class A and Class B common stock outstanding on the immediately preceding December 31 or such lesser number of shares as determined by the Company’s compensation committee. On each of January 1, 2023 and 2022, the shares available for grant under the 2016 ESPP were automatically increased by 1,800,000 shares.
The 2016 ESPP allows eligible employees to purchase shares of the Company’s Class A common stock at a discount of 15% through payroll deductions of their eligible compensation, subject to any plan limitations. The 2016 ESPP provides for separate six-month offering periods beginning in May and November of each year.
On each purchase date, eligible employees purchase the Company’s stock at a price per share equal to 85% of the lesser of (i) the fair market value of the Company’s Class A common stock on the offering date or (ii) the fair market value of the Company’s Class A common stock on the purchase date.
As of December 31, 2023, total unrecognized compensation cost related to the 2016 ESPP was not significant.

In March 2022, the Company granted 919,289 shares of performance-based restricted stock units (“PSU”) to certain of its executive employees. These awards activity is included in the table above. The PSUs were granted with a grant date fair value per share of $157.44 and an aggregate grant date fair value of $144.7 million. The Company estimated the fair value of these awards based on the closing price of its Class A common stock on the date of grant. Each PSU award consisted of three tranches that vest separately over distinct service periods if its respective performance targets, as defined in the grant agreements, are achieved in the respective periods. The final vesting is determined by the Company’s Compensation Committee subsequent to the completion of the vesting period. The vesting of the first tranche was based on achievement of revenue growth targets with respect to the year ended December 31, 2022. The vesting of the second and third tranches was based on both (a) revenue growth targets and (b) profitability targets achievement with respect to each of the years ended December 31, 2023 and 2024. If performance targets are not achieved, the related tranches are forfeited. Vesting of these performance-based restricted stock unit awards can range up to 100% above the target based on levels of performance and is recorded in stock-based compensation expense in the year during which each tranche vests.
As of December 31, 2023, total unrecognized compensation cost related to unvested RSUs was $1.5 billion, which will be amortized over a weighted-average period of 2.7 years.

State tax credits$120,300 Indefinite
Foreign net operating loss carryforwards$1,011,800 Indefinite
A limitation may apply to the use of the net operating loss and credit carryforwards, under provisions of the Internal Revenue Code of 1986, as amended, and similar state tax provisions that are applicable if the Company experiences an “ownership change.” An ownership change may occur, for example, as a result of issuance of new equity. Should these limitations apply, the carryforwards would be subject to an annual limitation, resulting in a potential reduction in the gross deferred tax assets before considering the valuation allowance.
Rule 10A-3The Company's accounting for deferred taxes involves the evaluation of a number of factors concerning the realizability of its net deferred tax assets. The Company primarily considered such factors as its history of operating losses, the nature of the Company's deferred tax assets, and the timing, likelihood and amount, if any, of future taxable income during the periods in which those temporary differences and carryforwards become deductible.
At present, the Company does not believe that it is more likely than not that the federal, state and foreign net deferred tax assets will be realized, and accordingly, a valuation allowance has been established. The valuation allowance increased by approximately $176.6 million and $220.5 million during the years ended December 31, 2023 and 2022, respectively.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
Year Ended December 31,

Lapse of statute of limitations(1,239)(1,040)— 
Unrecognized tax benefit, end of year$233,778 $228,966 $223,380 
As of December 31, 2023, the Company had approximately $233.8 million of unrecognized tax benefits. If the $233.8 million is recognized, $5.1 million would affect the effective tax rate. The remaining amount would be offset by the reversal of related deferred tax assets which are subject to a full valuation allowance.
The Company recognizes interest and penalties, if any, related to uncertain tax positions in its income tax provision. As of December 31, 2023, 2022 and 2021, such amounts are not significant.
The Company does not anticipate any significant changes within 12 months of December 31, 2023, in its uncertain tax positions that would be material to its consolidated financial statements taken as a whole because nearly all of the unrecognized tax benefit has been offset by a deferred tax asset, which has been reduced by a valuation allowance.
The Company files U.S. federal income tax returns as well as income tax returns in many U.S. states and foreign jurisdictions. As of December 31, 2023, the tax years 2008 through the current period remain open to examination by the major jurisdictions in which the Company is subject to tax. Years outside the normal statute of limitation remain open to audit by tax authorities due to tax attributes generated in those early years, which have been carried forward and may be audited in subsequent years when utilized. The Company is fully reserved for all open U.S. federal, state and local, or non-U.S. income tax examinations by any tax authorities.
On June 7, 2019, a three-judge panel from the U.S. Court of Appeals for the Ninth Circuit overturned the U.S. Tax Court's decision in Altera Corp. v. Commissioner and upheld the portion of the Treasury regulations under Section 482 of the Internal Revenue Code that requires related parties in a cost-sharing arrangement to share expenses related to share-based compensation. As a result of this decision, the Company's gross unrecognized tax benefits increased to reflect the impact of including share-based compensation in cost-sharing arrangements. On July 22, 2019, Altera filed a petition for a rehearing before the full Ninth Circuit and the request was denied on November 12, 2019. On February 10, 2020, Altera filed a petition to appeal the decision to the Supreme Court and on June 22, 2020 the Supreme Court denied the petition. There is no impact on the Company’s effective tax rate for years ended December 31, 2023 and 2022 due to a full valuation allowance against its deferred tax assets. We will continue to monitor future developments and their potential effects on our consolidated financial statements.
The provision for and benefit from income taxes recorded in the years ended December 31, 2023 and 2022, respectively, consist primarily of income taxes, withholding taxes in foreign jurisdictions in which the Company conducts business and the tax benefit related to the release of valuation allowance from acquisitions. The Company’s U.S. operations have been in a loss position and the Company maintains a full valuation allowance against its U.S. deferred tax assets.

Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K.

Table of Contents
Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of December 31, 2023, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the NYSE Listing Standardstime periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.
Management's Annual Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and the LTSE Listing Standards. Compensationpreparation of financial statements for external purposes in accordance with U.S generally accepted accounting principles.
Under the supervision and talentwith the participation of our Chief Executive Officer and our Chief Financial Officer and oversight of the board of directors, our management committee members must also satisfyconducted an evaluation of the additional independenceeffectiveness of our internal control over financial reporting as of December 31, 2023, based on the criteria set forth in RuleInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.
10C-1The effectiveness of our internal control over financial reporting as of December 31, 2023 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the NYSE Listing Standardsthree months ended December 31, 2023, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Our management, including our Chief Executive Officer and our Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the LTSE Listing Standards.objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the organization have been detected. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost‑effective control system, misstatements due to error or fraud may occur and not be detected.

Item 11. Executive Compensation
The information required by this item is incorporated by reference to the Proxy Statement to be filed with the SEC within 120 days of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that Messrs. Dalzell, Deeter, Epstein, Immelt and Patrick, and Mses. Donio, Dubinsky and Rottenberg do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the NYSE Listing Standards and LTSE Listing Standards. In making these determinations, our board of directors considered the current and prior relationships that each
non-employee
director has with our Company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each
non-employee
director, and the transactions involving them described above.
