For example, we outsource a substantial majority of our cloud infrastructure to Amazon Web Services (“AWS”), which hosts our products and platform. Our customers need to be able to reliably access our platform, without material interruption or degradation of performance. AWS runs its own platform that we access, and we are, therefore, vulnerable to service interruptions at AWS. We have experienced, and expect that we may experience interruptions, delays and outages in service and availability in the future due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints. Capacity constraints could be caused by a number of potential causes, including technical failures, natural disasters, public health epidemics or pandemics, fraud or security attacks. In addition, if our security, or that of AWS, is compromised, if our products, platform or customer data become unavailable, or if our users are unable to use our products within a reasonable amount of time or at all, any one of which may be due to circumstances beyond our control, then our business, results of operations and financial condition could be adversely affected. In some instances, we may encounter difficulties or otherwise not be able to identify the cause or causes of these performance problems within a period of time acceptable to our customers. It may become increasingly difficult to maintain and improve our platform performance and to troubleshoot performance issues, especially during peak usage times, as our products become more complex and the usage of our products increases. To the extent that we do not effectively address capacity constraints, either through AWS or alternative providers of cloud infrastructure, or through other factors that may result in interruptions, delays and outages in service and availability of our products and/or services, our business, results of operations and financial condition may be adversely affected. In addition, if Amazon.com, Inc. (“Amazon”) requires that we comply with unfavorable terms in order to continue our use of AWS or if Amazon implements any changes in its service levels for AWS, the changes may adversely affect our ability to meet our customers’ requirements, result in negative publicity which could harm our reputation and brand and may adversely affect the usage of our platform.

In November 2023, September 2025, the Financial Accounting Standards Board (“FASB”) FASB issued Accounting Standards Update No. (“ASU”) 2023-07, “Segment Reporting (Topic 280): ASU 2025-06, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to Reportable Segment Disclosures,” the Accounting for Internal-Use Software,” which is intended to improve reportable segment disclosures. The modernizes the accounting for internal-use software by replacing the previous stage-based model and aligning the capitalization process with current development practices, especially agile and iterative methods. ASU expands segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of segment profit or loss. It also requires disclosure of the amount and description of the composition of other segment items and interim disclosures of a reportable segment's profit or loss and assets. ASU 2023-07 2025-06 is effective for fiscal years annual reporting periods beginning after December 15, 2023, 2027, and interim periods within fiscal years beginning after December 15, 2024, with retrospective application required. may be applied prospectively, retrospectively, or using a modified transition approach.

AddedRisk Factors
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.
AddedRisk Factors
•seasonal trends, including due to increased consumer activity in the fourth quarter;
AddedRisk Factors
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.
AddedRisk Factors
We also face risks related to losing access to these services. Many of these providers do not have long-term committed contracts with us and may interrupt services or terminate their agreements with us without notice. We may not be able to replace these services on a cost-effective basis, or at all, and even if we can, replacing providers may be time-consuming, costly and result in delays.
AddedRisk Factors
We depend upon our IT systems to conduct virtually all of our business operations, ranging from our internal operations and research and development activities to our marketing and sales efforts and communications with our customers, vendors and other business partners. Moreover, our platform stores, transmits, and otherwise processes our, our customers’ and our partners’ proprietary, confidential, and sensitive data. We also rely on various third-party service providers – including network service providers, internet service providers, telecommunications carriers, and providers of cloud infrastructure and cloud communications – for business operations, to operate our platform and to deliver our products, as well as third-party technology and intellectual property.
AddedRisk Factors
We have been targeted by threat actors seeking unauthorized access to our systems or data, or that of our customers or third-party service providers, or to disrupt our operations or ability to provide our services. Our third-party service providers have also been targeted. Our platform and our underlying infrastructure, the information we store and process, and those of our third-party service providers, are subject to evolving threats and have in the past and may in the future be subject to breaches, compromises, disruptions, or other incidents, including as a result of the following:
AddedRisk Factors
•fraud, social-engineering attacks (such as phishing) and other third-party attempts to induce our employees, customers or partners to disclose sensitive information to gain access to our customers’ data or systems, or our data or our systems;

AddedRisk Factors
•efforts by hackers or sophisticated groups, such as criminal organizations, state-sponsored organizations or nation-states, to launch coordinated cyberattacks on internally built infrastructure or on third-party cloud-computing platform providers, including malicious code, ransomware, destructive malware, supply chain attacks and distributed denial-of-service attacks;
AddedRisk Factors
•third-party attempts to abuse our marketing, advertising, messaging or products and functionalities to impersonate persons or organizations and disseminate information that is false, misleading or malicious;
AddedRisk Factors
•attacks on, malfunctions or unavailability of, or other vulnerabilities in, the underlying networks and services that power the internet or that our products otherwise depend on, many of which are not under our control or the control of our customers or partners;
AddedRisk Factors
•employee fraud, misconduct or error, including resulting from efforts to bribe, extort, infiltrate or otherwise compromise our or our service providers’ workforce.
AddedMD&A
We envision a world in which every digital interaction is amazing. By combining our leading communications capabilities with rich contextual data and AI, we provide the infrastructure for businesses of all sizes to revolutionize how they engage with their customers by delivering seamless, trusted, and personalized customer experiences at scale.
AddedMD&A
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.
AddedMD&A
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.
AddedMD&A
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.
AddedMD&A
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.
AddedMD&A
