Customers may terminate or reduce their use of our products, or we may fail to attract new customers, 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, our failure to maintain performance, reliability, security, integrity or availability of our products and infrastructure to the satisfaction of our customers, or customers’ use of competitors’ products. For example, prior instances of disruptions in our cloud communications platform have impacted our customers’ ability to use products on our platform for up to several hours at a time. Issues with our products have had, and in the future may have, an adverse impact on customer satisfaction and our ability to retain or attract customers and have caused, and may in the future cause, us to incur certain costs associated with offering credits to our affected customers.

Removed

If our sales and marketing efforts do not attract new customers or we are unable to sell additional products to our existing customers effectively and in a cost-efficient manner, our business, results of operations and financial condition would be adversely affected.

Removed

To grow our business, we must continue to attract new customers, increase usage of our existing products and new product adoption by existing customers, and successfully market new products, including products with higher gross margins, in a cost-effective manner. Our sales and marketing teams work closely together to drive awareness and adoption of our platform. We leverage our brand, marketing programs, developer network and conferences, such as SIGNAL, to expand our go-to-market motions. Our go-to-market model has three motions: our self-service platform, primarily aimed at developers, marketers, and other technical users; our direct sales motion, primarily aimed at enterprise and commercial customers; and our partner-led motion, including resellers, distributors, and strategic partners, such as independent software vendors, technology partners and systems integrators, which is primarily aimed at customers who do not have the available developer resources to build their own applications. If the costs of the marketing channels we use increase, then we may choose to use alternative or 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 changes to the organization of our sales force, and we cannot guarantee that any such investments or changes will lead to wider adoption of our products or to the cost-effective acquisition of additional customers or increased revenue from existing customers as quickly or to the extent that we expect, or at all. In addition, new products that we develop or markets that we pursue may require increasingly sophisticated and more costly sales efforts and result in a longer sales cycle. If we are unable to maintain effective sales and marketing programs, our ability to efficiently attract new customers and increase revenue from existing customers could be adversely affected.

Removed

In addition, in recent years, we have reduced the size of our sales force to drive further efficiencies in our sales operations. With a more streamlined workforce, we are continuing to improve and rely more heavily on our use of self-service capabilities to drive sales of our products to customers that do not require direct account coverage. Additionally, we are introducing AI and automation in our self-service platform aimed at improving sales and customer support. Our self-service capabilities may not be as effective as we anticipate in driving adoption or increased usage of our products, or may take longer than we expect to drive growth.

Removed

If our efforts to increase the adoption and usage of our products or sell additional products to existing customers are more expensive or time-consuming than we expect or otherwise ineffective, then our business, results of operations and financial condition would be adversely affected.

Removed

If we are unable to increase adoption of our products by new customers, including enterprises, our business, results of operations and financial condition may be adversely affected.

Removed

Historically, a majority of our Active Customer Accounts have been acquired through the adoption of our Communications API products by software developers using our self-service model.

Removed

As our platform and market evolves and we seek to increase our customer base and achieve broader market acceptance of our products, we must effectively adapt our sales motions and navigate challenges presented by these customers and markets. In addition to continuing to improve our self-service platform aimed at developers, marketers, and other technical users, we are also focusing increasingly on sales to enterprises, such as through our Segment product, which is primarily aimed at complex customer data platform implementations at larger companies, and additional product innovations combining our communications products with contextual data and AI. As we seek to increase the adoption of our products by enterprises, we expect to encounter higher costs and more complex sales efforts for these customers.

Removed

Our ability to expand our customer base, including among enterprises, and to succeed in evolving markets will also depend, in part, on our ability to effectively attract and retain sales employees with relevant experience and organize, focus and train our sales, marketing and other employees. We have made, and may in the future make, changes to the organization of our sales force and sales motions in response to changes in company strategy, new market opportunities, new products or features, sales performance or effectiveness, changes in sales headcount, changes to the compensation structure of our sales organization, or other factors. Such changes have resulted, and may in the future result, in a reduction of productivity, which could negatively impact our growth rate and results of operations.

Removed

For enterprises, 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 result in higher costs and longer sales cycles. In addition, some enterprise customers may not use our products enough for us to generate revenue that justifies our 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 or partners, 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. If we are unable to successfully navigate the challenges posed by enterprise customers, our ability to acquire or benefit from enterprise customer relationships may be undermined and our business, results of operations and financial condition may be adversely affected.

Removed

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, regulations, and industry standards.

Removed

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 introduce compelling new products and enhancements that reflect the changing nature of our markets, technology, industry standards, and customer needs and preferences. For example, we are focused on continued product innovations to combine our communications products with contextual data and AI in order to address evolving customer needs and expectations. 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, the ability to provide rapid time-to-value for our customers, 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 at times driven by our developer community and may be outside of our control.

Removed

The current and prospective markets for our products 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 to meet current and prospective customer needs. 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 increased 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 have committed, and expect to continue to commit, significant resources to developing new products and enhancements 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, or more efficiently, quickly, conveniently or 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.

Removed

If we are unable to successfully and cost-effectively increase adoption and usage of our existing products, develop and drive adoption of new products, anticipate and keep pace with changes in technology, customers’ needs and expectations, and industry standards, or provide rapid time-to-value to our current and prospective customers, our business, results of operations and financial condition would be adversely affected.

Removed

The providers of third-party products with which our products are integrated 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. 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 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, last year we launched a new channel using Rich Communication Services (“RCS”) and we are working on a channel for Apple Messages for Business. We are also focused on Segment’s interoperability across the data ecosystem. Third-party platforms may also implement changes to their policies or practices regarding privacy or other matters that may adversely impact us or our customers. In addition, our network service providers, mobile device operating system providers or inbox service providers may adopt new filtering technologies in an effort to combat spam or robocalling. For example, Apple, Google, Yahoo and other mobile device 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. Such technologies may inadvertently filter desired messages or calls to or from our customers. If mobile device operating system providers, inbox service providers or 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.

Given that a majority of our revenue is usage-based and therefore 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 subscription revenue. Additionally, increased prices resulting from the effects of tariffs and inflation could increase our operating expenses.

Reworded

Adverse macroeconomic conditions have in the past resulted in, and may continuein tothe future result in, decreased or delayed 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 collect accounts receivable, all of which could negatively affect revenue and revenue growth. Additionally, our customers may be affected by changes and uncertainty in the U.S.global political environment couldwith leadrespect to changes in macroeconomic conditionstrade and toother policies.

Added

Macroeconomic and political conditions and uncertainties have in the past adversely affected, and may in the future adversely affect, our business, results of operations and financial condition, and could exacerbate many of the other risks described in this “Risk Factors” section.

Removed

If customers fail to pay us or reduce their spending with us as a result of adverse macroeconomic or geopolitical conditions or otherwise, we may be required to take steps to enforce the terms of our contracts and collect amounts due, including through litigation, which could increase our operating expenses. For example, in February 2023, one of our customers, Oi SA, a Brazilian telecom company, initiated reorganization proceedings in a Brazilian bankruptcy court as well as a secondary proceeding under Chapter 15 in the United States and exposed us to risks on collections of pre-petition receivables and ongoing revenue, as detailed in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations.” If macroeconomic and geopolitical conditions and uncertainties 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 “Risk Factors” section will be exacerbated.

Reworded

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.decline.

Added

Our sales and marketing strategies, and their effectiveness, are influenced by numerous factors. We have made, and may in the future make, changes to the organization of our sales force and sales motions in response to changes in company strategy, new market opportunities, new products or features, sales performance or effectiveness, changes in sales headcount, changes to the compensation structure of our sales organization, or other factors.

We may not be able to develop new products or product enhancements that achieve market acceptance, or adapt and respond effectively to rapidly changing technology, regulations, industry standards, or customer needs and preferences.

Added

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 introduce compelling new products and enhancements that reflect the changing nature of our markets, technology, industry standards, and customer needs and preferences. Anticipating these factors requires that we allocate significant resources without any guarantee that our investments of these resources will result in increased adoption of our products by current and prospective customers. For example, we have committed, and expect to continue to commit, significant resources towards developing new products and enhancements by combining our communications products with contextual data and AI. The success of any enhancements or new products depends on several factors, including timely completion, adequate quality testing, actual performance quality, market-accepted pricing levels, customer value and the ability to provide rapid time-to-value for our customers, and the emergence of competing products and services that may be delivered at lower prices, more efficiently, conveniently or securely, or render our products obsolete.

As part of our growth strategy, we have in the past reorganized, and may in the future reorganize, our business or change our reporting structure, which requires significant expenditures, allocation of valuable management resources and significant demands on our operational and financial infrastructure. Any anticipated benefits from any restructuring initiatives we may take may be realized later than expected or not at all, and the ongoing costs of implementing these measures may be greater than anticipated. Additionally, 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 business and operating model, then our business, results of operations and financial condition could also be adversely affected.

The current and prospective markets for our products are rapidly evolving, significantly fragmented and highly competitive, in some cases with relatively low barriers to entryentry, inand somemay segments.fail to grow as expected or decline over time. The principal competitive factors of these markets include completeness of offering, credibility with customers, ability to differentiate our products against competing offerings, 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.products, as well as our customers’ perception of the value and necessity of our products and platform. 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, (iii) regional network service providers that offer limited developer functionality on top of their own physical infrastructure, (iviii) customer relationship management and customer experience vendors andvendors, (viv) standalone customer data platform vendors.vendors and (v) other software companies that compete with portions of our product line.

Reworded

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 have in the past and may in the future develop and market products and services with comparable functionality to our products, and this could lead us to decrease prices in order to remain competitive. In addition, customers may reduce or delay spending on our products or substitute alternative solutions in response to pricing pressures, budget constraints or changing business priorities.

Reworded

With the introduction of new products and services and new market entrants, we expect competition to intensify in the future. Industry developments and evolving technology, such as AI, may also impact our competitive landscape and the factors required to compete effectively in current or prospective markets. Our ability to grow will depend in part on our success in expanding the scope of our products and entering new markets, and there can be no assurance that the markets will grow or that our products will achieve meaningful adoption within them. 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 activityactivity, 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.

Reworded

Our business, results of operations and financial condition also depends, in part, on our ability to establish, maintain and expand relationships through resellers, distributors, and strategic partners, including independent software vendors,ISVs, technology partners and systems integrators. 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 parties could adversely affect our revenue and other results of operations.

The markets for our products continue to evolve and may decline or experience limited growth.

Removed

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 customers 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 and to enter into new markets. Our ability to do so depends upon a number of factors, including the cost, performance and perceived value associated with our 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 grow or demand for our products decreases, then our business, results of operations and financial condition could be adversely affected.

WeWhile we achieved net income of $33.8 million in the year ended December 31, 2025, we have incurred net losses in each preceding year since our inception, including net losses of $109.4 million, $1.0 billionmillion and $1.3$1.0 billion in the years ended December 31, 2024, 20232024 and 2022,2023, respectively. We had an accumulated deficit of $7.5 billion as of December 31, 2024. In addition, while we have experienced revenue growth in prior periods, it is not indicative of future revenue growth, and our revenue and revenue growth for any quarterly or annual period should not be relied upon as an indication of our future revenue or revenue growth for any future period. If we are unable to generate and sustain increased revenue levels and manage our operating expenses, we may not become profitableachieve and achieve our statedsustain profitability goals and, even if we do, we may not be able to maintain or increase our level of profitability.profitability or achieve our stated profitability goals. As we implement additional initiatives to increase revenue, our operating expenses may continue to rise over the long term, potentially including, 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 if our revenue growth does not meet estimates, we may not be able to offset our associated operating expenses, which could prevent us from achieving and sustaining profitability, or maintaining or increasing cash flow. 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.

We interconnect with fixed and mobile network service providers around the world to deliver our products. Although we have, or are in the process of acquiring, authorization to provide voice and messaging services and for direct access to phone numbers in many countries, we expect to continue to rely to some extent on network service providers for these services. Reliance on network service providers subjects us to regulatory, competitive and other industry related changes over which we have little or no control. In addition, our reliance on network service providers subjects us to fees, penalties, administrative and technical requirements, each of which are subject to change. Similarly, in some cases, we utilize intermediaries for direct access to networks. Although we have, or are in the process of securing, direct connections with network service providers in many countries, we expect to continue to rely on intermediaries for these services to some extent. These intermediaries also charge us changing fees and at times have offerings that compete directly with our products. We also interconnect with internet service providers around the world to deliver our email products, and expect to continue to rely on such providers.

Added

Reliance on these providers poses risks to the quality of our services, primarily by limiting our control, operating flexibility, and ability to timely identify and respond to necessary service changes, and by subjecting us to service interruptions or outages. Reliance on such providers in the past has caused, and may in the future cause, errors, service outages, security incidents, or poor-quality communications on our products, and we could encounter difficulty identifying the source of the problem. This has in the past, and may in the future, cause harm to our brand, result in lost revenue, and cause us to lose existing and prospective customers.

Added

The fees we pay to these providers also subject us to risks. We are exposed to significant fluctuations in applicable fees paid to network service providers, intermediaries, and internet service providers. These fees are outside of our control and we are not able to predict the magnitude or timing of changes to such fees. Additional or increased fees charged by such providers have resulted, and could in the future result, in increases to our costs and other impacts on our financial results. For example, recent increases to A2P messaging fees charged by major U.S. mobile carriers are expected to create a modest headwind on our margins going forward, and such fees may increase further over time. In some markets, fees charged by our network service providers change daily or weekly. We may not be able to change our customer pricing as rapidly, and absorbing these costs could adversely affect our business and results of operations. Further, even when we do pass fee increases through to customers, it typically increases revenue and cost of revenue such that while gross profit dollars are not impacted, it has a negative impact on gross margins. While historically we have responded to many fee increases through negotiating efforts, absorbing increased costs or passing fees through to customers, we may be unable to respond in these ways in the future without a material negative impact to our business. Our ability to respond to fee increases may also be constrained by equivalent increases by other providers in a particular market, fees that are disproportionately large compared to underlying prices paid by our customers, or market or other conditions limiting our ability to increase the prices we charge for our products.

On January 1, 2025, we realigned our business unit structure into a functional support model under one organization. We believe that operating as one organization best positions us as we seek to deliver one trusted, smart and integrated platform that enables more personalized communications and engagements for customers. In the third quarter of 2025, we modified the presentation of the financial information that is regularly reviewed by our Chief Executive Officer, who is also our Chief Operating Decision Maker (“CODM”), to reflect this realignment and the change in how management currently views and operates the business. These changes required us to re-evaluate our operating segment structure and resulted in the conclusion that starting with the third quarter of 2025 and as of December 31, 2025, we had one operating and reportable segment, which comprised all of the consolidated Company.

On January 1, 2025, we realigned our business unit structure into a functional support model under one organization. We believe that operating as one organization best positions us as we seek to deliver one trusted, smart and integrated platform that enables more personalized communications and engagements for customers. Despite realigning our organizational structure, we continue to have two reportable segments. Our Communications reportable segment consists of a variety of APIs and software solutions to optimize communications between our customers and their end users. Our key offerings in our Communications reportable segment include Messaging, Voice, Email (which includes Marketing Campaigns), Flex, and User Authentication and Identity. Our Segment reportable segment consists of software products that enable businesses to leverage their contextual data to create unique customer profiles and achieve more effective customer engagement. Our key offering in our Segment reportable segment is our Segment product.

In the years ended December 31, 2024, 2023, and 2022, our revenue was $4.5 billion, $4.2 billion and $3.8 billion, respectively, and our net loss was $109.4 million, $1.0 billion and $1.3 billion, respectively. In the years ended December 31, 2024, 2023, and 2022, our 10 largest Active Customer Accounts generated an aggregate of 10%, 10% and 12% of our total revenue, respectively.

We are focused on innovation, profit,innovation and durable, profitable growth. To increase revenue and grow market share, we intend to drive product innovation, leverage predictive and generative AI, further enhance our ISV,independent software vendor (“ISV”), reseller and other partner relationships, improve our self-service capabilities, cross-sell our products, and expand internationally, enhance Segment data warehouse interoperability, and reduce time to value for Segment.internationally. We also intend to optimize our business and take measures to reduce costs, including simplifying and further automating our business processes, modernizing our infrastructure, focusing on self-service, leveraging AI, enacting certain workforce planning initiatives, optimizing utilization of our distributed workforce and implementing other initiatives targeted at improving efficiencies in our business. We are focused on driving leverage through these cost savings and efficiency initiatives, as well as efforts to drive growth in higher margin products.

Reworded

Our gross profit and gross margin are impacted by a number of factors, including our product mix; our ability to manage our cloud infrastructure‑related and network service provider fees, including A2P SMSmessaging fees; changes in foreign exchange rates; the timing of amortization of capitalized software development costs and acquired intangibles; the extent to which we periodically choose to adjust prices of our products; and the timing and extent of our investments in our operations. Our gross margin is also impacted by the mix of U.S. messaging termination compared to international messaging termination, as international messaging has lower gross margins.

Added

In June 2025, a major U.S. mobile carrier increased network service provider fees for A2P messages delivered to its subscribers. Other major U.S. carriers have since followed suit, with fee increases effective in January and April 2026. We pass these fees through to our customers at cost. As a result, we recognize an equal amount of revenue and cost of revenue related to these fees. The increased fees do not impact our gross profit, but they will create a modest headwind to our gross margins going forward. Such fees may increase further over time.

Added

As of December 31, 2025, we had an accrued bonus liability of $136.2 million related to our company-wide bonus program recorded in accrued expenses and other current liabilities in our consolidated balance sheet included elsewhere in this Annual Report on Form 10-K. The bonus payout will be determined for each eligible recipient based on Company and individual performance metrics and paid in March 2026, which we expect to impact our cash flows in the first quarter of 2026.

Added

Given our recent history of generating net income in the U.S., we believe that there is a reasonable possibility that within the next twelve months sufficient positive evidence may become available to allow us to determine that a significant portion of the valuation allowance recorded against our U.S. deferred tax assets should be released. The reversal would result in a significant income tax benefit for the period when we release the valuation allowance in the U.S. However, the exact timing and amount of the valuation allowance release are subject to change based on our actual operating results.

Added

Our results of operations have in the past been, and could in the future be, impacted by adverse macroeconomic conditions. We are continuing to monitor actual and potential effects of recent macroeconomic and political conditions and uncertainty on our business. For additional details, see Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.

We migrated part of Segment’s architecture to a new infrastructure provider in 2024, which we expect will allow us to recognize greater operational efficiency and scale up new AI-driven products and features. This migration resulted in overlapping expenses with our original and new vendors for much of 2024, which negatively impacted Segment gross margins. The migration was largely completed as of December 31, 2024.

In 2024, we introduced a company-wide annual cash bonus program to reduce our use of equity compensation. The bonus payout amount for each eligible participant is determined based on the Company and the individual full year performance metrics. In the year ended December 31, 2024, we recorded $134.1 million of expense related to this program. The program provided for a 25% mid-year bonus cash payment in its initial year only, which resulted in a $24.3 million cash payment in July 2024. As of December 31, 2024, the accrued bonus liability was $109.8 million recorded in the accrued expenses and other current liabilities in our consolidated balance sheet included elsewhere in this Annual Report on Form 10-K. The bonus will be paid in March of 2025. The introduction of this bonus program and reduction of our use of equity compensation impacted our expenses commencing in 2024. We expect that the reduction of our use of equity compensation will reduce our operating expenses in future periods.

In February 2023, one of our customers, Oi SA, a Brazilian telecom company, initiated reorganization proceedings in a Brazilian bankruptcy court and exposed us to risks on collections of pre-petition receivables and ongoing revenue. In April 2024, the creditors of Oi SA approved a Judicial Reorganization Plan (the “Oi Reorganization Plan”) that aims to ensure Oi SA’s operational feasibility and continuity of activities and further provides extended and discounted payment terms for pre-petition receivables. The Oi Reorganization Plan was subsequently ratified by the Brazilian bankruptcy court and contains various contingencies. As a result of a reduction in ongoing payment activity from this customer, as of December 31, 2024, we have fully reserved the pre-petition and post-petition accounts receivable due from Oi SA of $15.2 million and $13.5 million, respectively.

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.thousand.

Reworded

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, 2024, our Dollar-Based Net Expansion Rate excludes the contributions from acquisitions made after October 1, 2023. 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, 2024, our Dollar-Based Net Expansion Rate excludes the contributions from divestitures made after December 31, 2023. 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.

Reworded

We believe that measuring Dollar-Based Net Expansion Rate, on an aggregate basis and at the segment level,Rate 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.

Reworded

The majority of our Communications reportable segment revenue is derived from usage-based fees. The usage-based fees are earned when customers access our cloud-based platform and start using our products. Examples of our primarily usage-based Communications 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. Examples of our primarily subscription-based Communications products are Email (which includes Marketing Campaigns) and Flex.Segment. For subscription-based revenue derived from these products, we recognize revenue evenly over the contract term. When our usage-based products are embedded into our subscription-based products, or when multiple products are purchased together as a solution, we charge for each product separately on a usage or subscription basis, as applicable.

Most of our usage-based customers gain access to our platform through oura self-service sign-up format,process, 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, 2024,2025, 20232024 and 2022,2023, we generated 72%,74%, 71%72% and 73%71% of our revenue, respectively, from usage-based fees.

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 consumption of these costs.

Reworded

Our arrangements with network service providers require us to pay fees, including 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.

Comparison of Fiscal Years Ended December 31, 2025, 2024 and 2023

Added

In 2025, revenue increased by $609.2 million, or 14%, compared to the same period last year. This increase was primarily attributable to the increased usage of our products by our existing customers, as reflected in our Dollar‑Based Net Expansion Rate of 108%, as well as an increase of $242.0 million in revenue derived from our new Active Customer Accounts. The increase also reflects $49.5 million in revenue related to the incremental A2P fees introduced by a major US carrier in June 2025.

Added

In 2025, cost of revenue increased by $408.7 million, or 19%, compared to the same period last year. This increase was primarily attributable to a $362.4 million increase in network service providers’ costs, net of the impact of the hedging instruments, which includes $49.5 million of the incremental A2P fees introduced by a major U.S. carrier during 2025.

In 2025, gross profit increased by $200.5 million, or 9%, compared to the same period last year. This increase was attributable to the factors impacting our revenue and cost of revenue, as described above.

Added

In 2025, research and development expenses increased by $11.4 million, or 1%, compared to the same period last year. Fluctuations in the various research and development expense categories were not significant either individually or in the aggregate.

Added

In 2025, sales and marketing expenses increased by $12.4 million, or 1%, compared to the same period last year. Fluctuations in the various sales and marketing expense categories were not significant either individually or in the aggregate.

Added

In 2025, general and administrative expenses decreased by $38.4 million, or 9%, compared to the same period last year. The decrease was primarily attributable to a $27.2 million decrease in the provision for doubtful accounts due to strong collections and an improved aging profile of our accounts receivable, and a $13.2 million decrease in professional services fees.

Added

In 2025, restructuring costs increased by $1.8 million, or 13%, compared to the same period last year. The restructuring activities in both periods were not significant.

Added

In 2025, impairment of long-lived assets increased by $1.8 million, or 100%, compared to the same period last year. The impairment amount was not significant.

Added

In 2025, other expenses, net, increased by $67.8 million, or 194%, compared to the same period last year. The increase was primarily attributable to an $80.6 million impairment of our equity method investment described in Note 12 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. This increase was partially offset by an $8.2 million decrease in impairment of our strategic investments and a $7.3 million decrease in our share of losses from our equity method investment.

Comparison of Fiscal Years Ended December 31, 2024, 2023 and 2022

Removed

In 2024, Communications revenue increased by $301.6 million, or 8%, compared to the same period last year. This increase was primarily attributable to the increased usage of our products by our existing customers, as reflected in our Communications Dollar‑Based Net Expansion Rate of 105%, as well as $201.6 million in revenue derived from our new Communications Active Customer Accounts. These increases were partially offset by a decrease of $52.8 million related to revenue from our ValueFirst and Internet of Things (“IoT”) businesses, which we divested during 2023.

Removed

In 2024, Segment revenue increased by $2.4 million, or 1%, compared to the same period last year. This increase was primarily attributable to $28.9 million in revenue derived from our new Segment Active Customer Accounts, partially offset by the decreased usage of our products due to churn and contraction affecting our existing customers, as reflected in our Segment Dollar-Based Net Expansion Rate of 92%.

Removed

In 2023, Communications revenue increased by $308.6 million, or 9%, compared to the same period in the prior year. This increase was primarily attributable to a 5% increase in the number of Communications Active Customer Accounts from over 282,000 as of December 31, 2022, to over 297,000 as of December 31, 2023, as well as the increased usage of our products by our existing customers, as reflected in our Communications Dollar‑Based Net Expansion Rate of 103%. These increases were offset by a decrease of $59.8 million related to revenue from our ValueFirst and IoT businesses, which we divested during 2023.

Removed

In 2023, Segment revenue increased by $19.0 million, or 7%, compared to the same period in the prior year. This increase was primarily attributable to a 4% increase in the number of Segment Active Customer Accounts from over 7,700 as of December 31, 2022 to over 8,000 as of December 31, 2023. Our Segment Dollar‑Based Net Expansion Rate was 97% for the year ended December 31, 2023, due to higher contraction and customer churn compared to the same period in the prior year.

Removed

In 2024, cost of revenue increased by $69.8 million, or 3%, compared to the same period last year. This increase was primarily attributable to an $87.8 million increase in network service providers’ costs, net of the impact of the hedging instruments, and a $34.7 million increase in hosting fees, which support the growth in usage of our products by our new and existing customers. The increase was partially offset by a $50.5 million decrease in amortization of intangible assets.

Removed

In 2024, gross profit increased by $234.3 million, or 11%, compared to the same period last year. This increase was attributable to the factors impacting our revenue and cost of revenue, as described above.

Removed

In 2023, cost of revenue increased by $97.3 million, or 5%, compared to the same period in the prior year. This increase was primarily attributable to a $51.4 million increase in network service providers’ costs, net of the impact of the hedging instruments, and a $28.7 million increase in hosting fees, which support the growth in usage of our products by our new and existing customers. The increase was also attributable to a $20.3 million increase in amortization of capitalized internal-use software development costs due to additional internal-use software projects placed in service in 2023.

Removed

In 2023, gross profit increased by $230.4 million, or 13%, compared to the same period in the prior year. This increase was attributable to the factors impacting our revenue and cost of revenue, as described above.

Removed

In 2024, research and development expenses increased by $66.0 million, or 7%, compared to the same period last year. The increase was primarily attributable to a $53.6 million increase in total personnel costs despite a 16% decrease in average research and development headcount compared to the same period last year. The increase in personnel costs was primarily driven by an $80.1 million increase in bonus expenses as a result of the introduction of our new cash bonus program, partially offset by a $20.0 million decrease in salaries expense. The increase in research and development expenses was also attributable to a $14.9 million increase in hosting fees to support development and staging of our products and a $7.0 million increase in software subscription expenses. These increases were partially offset by an $11.9 million increase in capitalized internal-use software development costs.

Removed

In 2024, sales and marketing expenses decreased by $162.2 million, or 16%, compared to the same period last year. The decrease was primarily attributable to an $86.8 million decrease in total personnel costs, which was primarily driven by a 21% decrease in average sales and marketing headcount compared to the same period last year. The decrease in headcount was primarily driven by the restructuring of our workforce in February 2023 and December 2023. Sales and marketing expenses also decreased due to a $29.6 million decrease in amortization of intangible assets, a $22.3 million decrease in advertising expenses and a $9.7 million decrease in expenses related to corporate events.

Removed

In 2024, general and administrative expenses decreased by $19.4 million, or 4%, compared to the same period last year. The decrease was primarily attributable to the $32.3 million loss on divested net assets recorded in the 2023 period related to the sale of our ValueFirst and Internet of Things businesses and a $15.8 million decrease in the provision for doubtful accounts. The decrease in general and administrative expenses was partially offset by an $18.3 million increase in professional services fees and an $11.9 million increase in bonus expenses as a result of the introduction of our new cash bonus program.

Removed

In 2024, restructuring costs decreased by $152.5 million, or 92%, compared to the same period last year. The decrease was primarily attributable to the significant restructuring costs incurred in the 2023 period related to our February 2023 and December 2023 restructuring activities.

Removed

In 2024, impairment of long-lived assets decreased by $320.5 million, or 100%, compared to the same period last year. The prior year charges were related to the impairment of Segment intangible assets and the impairment of certain of our operating leases and other long-lived assets as a result of permanent office closures in 2023. There were no such impairments in the current period.

Removed

In 2023, research and development expenses decreased by $136.3 million, or 13%, compared to the same period in the prior 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.

Our sales and marketing strategies, and their effectiveness, are influenced by numerous factors. We have made, and may in the future make, changes to the organization of our sales force and sales motions in response to changes in company strategy, new market opportunities, new products or features, sales performance or effectiveness, changes in sales headcount, changes to the compensation structure of our sales organization, or other factors. Such changes may not lead to wider adoption of our products or to the cost-effective acquisition of additional customers or increased revenue from existing customers as quickly or to the extent we expect, or at all, and have resulted, and may in the future result, in a reduction of productivity, which could negatively impact our growth rate and results of operations. For example, we are focusing increasingly on solution selling and platform services. We are focused on driving efficiencies in our sales operations, and are continuing to improve and rely increasingly on our self-service capabilities to drive sales to customers that do not require direct account coverage. We are also introducing AI and automation in our self-service platform aimed at improving sales and customer support. In addition, we recently introduced a unified Twilio Console designed in part to streamline and facilitate initial onboarding and multi-product adoption. These efforts may not continue to be as effective as we anticipate in driving adoption or increased usage of our products, or may take longer than we expect to drive growth or increase efficiency. In addition, if the costs of the marketing channels we use increase, then we may choose to use alternative or less expensive channels, which may not be as effective as the channels we currently use.

Reworded

New products that we develop or markets that we pursue may require increasingly sophisticated and more costly sales efforts and result in longer sales cycles. AsFor example, in recent years, we seekhave expanded efforts to increase the adoption of our products by enterprises, we expect to encounter higher costs and more complex sales efforts for these customers.enterprises. For enterprises, the decision to adopt our products may require the approval of multiple technical and business decision makers, and enterprise customers may require extensive education about our products and significant customer support before they will commit to deploying our products at scale, which may place additional strain on our product and engineering resources. Enterprises may also engage in protracted pricing and contract negotiations, leading to higher costs and longer sales cycles. Enterprise customers may not use our products enough for us to generate revenue that justifies our cost to obtain such customers, or 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.

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 introduce compelling new products and enhancementsenhancements. thatOur platform and products must reflect theand changingrespond natureto of ourdynamic markets, technology, industry standards, and customer needs and preferences. Anticipating these factors requires that weWe allocate significant resources to product development without any guarantee that ourthese investments of these resources will result in increased adoption of our products by current and prospective customers. For example, we have committed, and expect to continue to commit, significant resources towards developing new products and enhancements by combining our communications products with contextual data and AI. The success of any enhancements or new products depends on several factors, including timely completion, adequate quality testing, actual performance quality, market-accepted pricing levels, customer value and the ability to provide rapid time-to-value for our customers, and the emergence of competing products and services that may be delivered at lower prices, more efficiently, conveniently or securely, or render our products obsolete. For example, if user authentication practices evolve to reduce or eliminate the use of one-time passwords, our revenue could be adversely affected. 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 at times driven by our developer community and may be outside of our control.

Reworded

The providers of third-party products with which our products are integrated 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. 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 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, including AI model providers, and we need to continuously modify and enhance our products and platform to adapt to new integrations and changes and innovation in integrated technologies which may present significant complexity, obstacles or other adverse impacts on our products or our business. For example, in 2025 we launched a new channel using Rich Communication Services (“RCS”) and we are working on a channel for Apple Messages for Business. We are also focused on the interoperability of our products across the data ecosystem. Third-party platforms may also implement changes to their policies or practices regarding privacy or other matters that may adversely impact us or our customers. In addition, our network service providers, mobile device operating system providers or inbox service providers may adopt new filtering technologies in an effort to combat spam or robocalling. For example, Apple, Google, Yahoo and other mobile device 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. Such technologies may inadvertently filter desired messages or calls to or from our customers. If mobile device operating system providers, inbox service providers or 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.

Reworded

We achieved net income of $33.8 million in the year ended December 31, 2025. However, we incurred net losses in each preceding year since our inception. Our past performance for any quarterly or annual period should not be relied upon as an indication of our performance for any future period. If we are unable to generate and sustain increased revenue levels and manage our operating expenses, we may not achieve and sustain profitability and, even if we do, we may not be able to increase our level of profitability or achieve our stated profitability goals. As we implement additional initiatives to increase revenue, our operating expenses may continue to rise over the long term, potentially including, 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, including computing costs associated with AI; 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 if our revenue growth does not meet estimates, we may not be able to offset our associated operating expenses, which could prevent us from achieving and sustaining profitability, or maintaining or increasing cash flow. 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.

Reworded

The fees we pay to these providers also subject us to risks. We are exposed to significant fluctuations in applicable fees paid to network service providers, intermediaries, and internet service providers. These fees are outside of our control and we are not able to predict the magnitude or timing of changes to such fees. Additional or increased fees charged by such providers have resulted, and could in the future result, in increases to our costs and other impacts on our financial results. For example, recent increases to A2P messaging fees charged by major U.S. mobile carriers create a headwind on our margins, and such fees may increase further over time. In some markets, fees charged by our network service providers change daily or weekly. We may not be able to change our customer pricing as rapidly, and absorbing these costs could adversely affect our business and results of operations. Further, even when we do pass fee increases through to customers, it typically increases revenue and cost of revenue such that while gross profit dollars are not impacted, it has a negative impact on gross margins. While historically we have responded to many fee increases through negotiating efforts, absorbing increased costs or passing fees through to customers, we may be unable to respond in these ways in the future without a material negative impact to customer demand and our business.business, results of operations and financial condition. Our ability to respond to fee increases may also be constrained by equivalent increases by other providers in a particular market, fees that are disproportionately large compared to underlying prices paid by our customers, or market or other conditions limiting our ability to increase the prices we charge for our products.

Reworded

We face risks associated with optimally pricing our products, particularly given the dynamic nature of our usage-based pricing. The fees that we pay to network service providers can vary, in some markets daily or weekly, differ across countries, and are affected by volume and other factors that may be outside of our control and which are difficult to predict. As a result, we may incur increased costs that we may be unable or unwilling to pass through to our customers. If we do pass increased fees through to our customers, it could adversely affect customer relationships and demand or cause customers to seek lower-cost alternatives.

Reworded

In the threesix months ended MarchJune 31,30, 2026 and the years ended December 31, 2025 and 2024, we derived 36%, 36% and 35% 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 strategically maintain and expand our customer base worldwide. Operating in international markets requires significant resources and management attention and subjects us to regulatory, economic and political risks in addition to those we face in the United States.

Reworded

From time to time, we may also divest or stop investing in certain businesses or products. The sale of a business or product has in the past and may in the future 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. 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. Divestitures or winding down businesses or products can also disrupt our customer, supplier and/or employee relationships and divert the time and attention of our management and employees. 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.

Breaches of or other incidents impacting our networks or systems, or those of our third-party service providers,providers and broader supply chain, 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.

Cyberattacks and other malicious activity continue to become more sophisticated, targeted and inexpensive to conduct, and to increase in frequency and magnitude.magnitude, particularly through the use of AI. These include ransomware and cyber extortion attacks, which can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may reduce the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments, such as due to applicable laws or regulations prohibiting such payments. Geopolitical tensions and events may further heighten risks we and our service providers face from breaches and other incidents.

Reworded

Additionally, as a provider of interconnected VoIP service,services, we must also comply with certain U.S. federal privacy laws and regulations, including Section 222 of the Communications Act of 1934, as amended, and the FCC’s customer proprietary network information rules. We are also subject to state rules and obligations that have been proposed or adopted, or may be in the future. We are also subject to other rapidly changing technology- and industry-specific laws, regulations and obligations. For example, we expect increased global regulation in the use of AI and ML such as the recent AI Act in Europe, which imposes onerous obligations related to the development, placement on the market and use of AI systems. Various countries and a growing number of U.S. states are also enacting legislation regulating aspects of AI or AI generally. We may need to change our business practices to comply with obligations under these or other new and evolving regimes, and face significant compliance challenges, liability, or other risks.

Reworded

The deployment of agentic AI — systems that autonomously execute multi-step tasks — introduces risks that are distinct from those of traditional AI features resulting from unintended or unauthorized actions that disrupt our internal operations and service delivery.delivery or create unknown or unexpected compliance risks. These risks may be difficult to monitor or prevent given the autonomous nature of such systems.

Added

Our ability to mitigate the risks associated with AI will depend on our effective maintenance, training, monitoring and enforcement of appropriate policies, procedures and controls governing the use of AI tools, the results of any such use by us and our partners, and compliance with such policies and procedures by our workforce. Any unauthorized use or misuse of AI by our employees undermines our ability to protect against the AI-related risks described above.

As a provider of communications products and a licensed telecommunications provider, we are required to comply with many changing federal, state and international regulations, including relating to privacy, security, telecommunications, consumer protection, fraud and scam prevention, Know Your CustomerCustomer, andKnow Your Upstream Provider, Know Your Traffic and other requirements and obligations, which often vary across the numerous jurisdictions in which we operate. Compliance with these requirements involves significant management attention and compliance costs, and can present operational challenges, onboarding delays and friction for our customers, require us to raise prices, restructure or discontinue our products, or limit our ability to expand into certain jurisdictions. If we do not comply with such requirements, we could face enforcement actions, significant fines, remedial directions to implement audits or new processes, loss of licenses, restrictions or prohibitions on our ability to operate or offer certain of our products, eroded customer trust, and damage to our brand and reputation, and other consequences. Any of the foregoing could adversely affect our business, results of operations and financial condition.

Reworded

We are also subject to varying international licensing obligations and communications regulations, including related to reporting requirements, provision of emergency services and of information to support emergency services, number portability, combatting scam and fraud, payment into universal service funds, and licensing fees, among others. As we expand into new countries, our potential regulatory and licensing obligations, and related scrutiny, increase. The international landscape continues to evolve, and in many cases involves significant uncertainties related to how the CPaaSour business model fits into the communications regulatory framework. There is significant variation in requirements across international jurisdictions, including as to whether some or all of the services we offer are considered regulated telecommunications services. In addition, 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, and users in such countries may continue to use our products in those countries notwithstanding the illegality or embargo, or a local partner that we use to provide services may not comply with applicable governmental regulations, subjecting us to potential penalties or governmental actions that may be costly, harm our business and damage our brand and reputation.

Reworded

Both in the United States and internationally, these requirements continue to change.change rapidly, increase in volume and complexity and involve heightened risks of enforcement and liability. For example, new federal, state, or international requirements could impose more or different robocall or robotext mitigation measures, limit the customers we are able to serve, extend telecommunications regulations to our non-interconnected VoIP services or messaging or other products, subject us to additional registration, reporting or resiliency compliance obligations, or subject us to other fees, taxes or obligations. The volume and changing nature of these requirements increases the associated compliance costs, operational challenges, customer friction, possibility of enforcement actions and other associated risks, and new or changed requirements, or interpretations or judicial actions related to them, may also adversely affect our business, results of operations and financial condition.

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, certain states 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 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.

In addition, the use of the internet as a business tool could be adversely affected due toby 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 cyberattacks, malicious software, and other security threats. 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.

We review our intangible assets, goodwill and equity method investment for impairment in accordance with applicable accounting requirements. As of MarchJune 31,30, 2026, we carried a net $5.4 billion of goodwill and intangible assets and $275.1$250.5 million related to our equity method investment. 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, have in the past resulted, and could in the future result, in a change to the estimation of fair value resulting in an impairment charge to the underlying asset. Our results of operations may be adversely affected as a result of any such charges. For example, during the year ended December 31, 2025, we recorded an impairment of our equity method investment totaling approximately $80.6 million, as described in additional detail in Note 12 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2025.

Reworded

Historically, we have not billed or collected indirect 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 $42.8$45.2 million on our MarchJune 31,30, 2026 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.

Reworded

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 affected depending on the applicability 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 assets 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 operations.

Changes in tax laws, including recently enacted2025 U.S. federal tax legislation commonly referred to as the One Big Beautiful Bill Act (the “OBBB Act”), or tax rulings, or changes in interpretations of existing laws, could cause us to be subject to additional taxes, which in turn could materially affect our financial position and results of operations. The OBBB Act could potentially increase our effective tax rate as we continue to expand our international operations in the coming years. 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.

In January 2025, our board of directors authorized the repurchase of up to $2.0 billion of our common stock from time to time through a share repurchase program. As of MarchJune 31,30, 2026, we had repurchased $1.1$1.2 billion of outstanding shares of our common stock under this program, such that approximately $892.0$826.0 million remained available for purchase as of such date. Under our share repurchase program, we may make repurchases of stock through a variety of methods, including open 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, 2027, 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 as 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.

In the second quarter of 2026, we determined that we would be unable to consume certain network services that we prepaid in previous periods due to operational and financial challenges experienced by two network service providers. This determination resulted in a $32.8 million impairment loss on prepaid assets that impacted our operating expenses and income from operations for the three and six months ended June 30, 2026. This impairment loss has no impact on our free cash flow and will not impact our results of operations in future periods.

We regularly assess the need for a valuation allowance on our deferred tax assets. As of June 30, 2026, based on our analysis of both positive and negative evidence, including the amount of pre-tax book income in the U.S. in recent periods and our expectation of future profits in the U.S., we concluded that it is more likely than not that the majority of our U.S. deferred tax assets are realizable. As a result, we released a significant portion of our valuation allowance on the net deferred tax assets in the U.S., resulting in the recognition of deferred tax assets and income tax benefit of $944.1 million during the three and six months ended June 30, 2026. For further detail refer to Note 14 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

In March 2026, we paid $141.0 million under our 2025 company-wide bonus program to eligible employees for amounts previously accrued. As previously disclosed, these payments impacted our cash flows in the first quarter of 2026.

Given our recent history of generating net income in the U.S., we believe that there is a reasonable possibility that during 2026 sufficient positive evidence may become available to allow us to determine that a significant portion of the valuation allowance recorded against our U.S. deferred tax assets should be released. This would result in a significant income tax benefit for the period when we release the valuation allowance in the U.S. However, the exact timing and amount of the valuation allowance release are subject to change based on our actual operating results.

Beginning in the first quarter of 2026, we have discontinued disclosure of Active Customer Accounts as a key metric. As a result, we are revising the definition of DBNE to remove references to Active Customer Accounts and Zipwhip accounts and instead refer to “customer accounts.” The methodology for identifying these customer accounts is unchanged from the methodology most recently used to identify Active Customer Accounts and this definitional update has no impact on our methodology for calculating DBNE or our historical or future DBNE.

Revenue

Reworded

Most of our usage-based customers gain access to our platform through a self-service process, 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 three months ended MarchJune 31,30, 2026 and 2025, we generated 75% and 73%74% of our revenue, respectively, from usage-based fees.

Reworded

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.

Benefit from (Provision for) Income Taxes

Reworded

Our benefit from (provision for) income taxes consists primarily of the tax benefit from the release of a significant portion of our U.S. valuation allowance; and also, federal, state and foreign income taxes and withholding taxes in foreign jurisdictions in which the Company conducts business. From time to time, we may recognize tax benefits arising from various matters, including newly enacted legislations. Benefits from income taxes may fully or partially offset the provision for income taxes within a reporting period.

Income Taxes

Added

We account for income taxes using 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 losses 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.

Added

We recognize 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 to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Added

We regularly assess the need for a valuation allowance on our deferred tax assets. In making that assessment, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of all available evidence, whether it is more-likely-than-not that some or all of our deferred tax assets will be realized. The determination of the realizability of deferred tax assets requires significant judgment and relies on management's estimates of future taxable income.

Added

As of June 30, 2026, we demonstrated sustained profitability in the U.S. over a cumulative period of three years based on the U.S. pre-tax book income adjusted for permanent book-tax differences, and we expect to continue to sustain this profitability position in the U.S. for the annual period ended December 31, 2026. This evidence is objective and verifiable and represents strong positive evidence that carries significant weight.

Added

Based on our analysis of all available positive and negative evidence, including the objective and verifiable positive evidence as described above, and anticipated future earnings, we concluded that it is more likely than not that the majority of our U.S. deferred tax assets are realizable. As a result of this change in estimate, we released a significant portion of the valuation allowance on our U.S. deferred tax assets in the current quarter. For further detail refer to Note 14 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Added

Our judgment regarding the need for a valuation allowance may reasonably change in future reporting periods due to many factors, including changes in expectations of future profitability in the U.S. and changes in tax laws or regulations. We will continue to maintain a valuation allowance against deferred tax assets where we believe that it is more likely than not that they will not be realized.

There have been no other changes to our critical accounting policies and estimates as described in our Annual Report on Form 10-K filed with the SEC on February 24, 2026.
