Segment Reporting Segment Reporting
As of December 31, 2024, the Company had two operating and reportable segments: Twilio Communications (“Communications”) and Twilio Segment (“Segment”).
Twilio Communications: The Communications segment consists of a variety of application programming interfaces (“APIs”) and software solutions to optimize communications between Twilio customers and their end users. The key products from which the segment derives its revenue are Messaging, Voice and Email.
Twilio Segment: The Segment segment consists of software products that enable businesses to achieve more effective customer engagement by providing the tools necessary for customers to build direct, personalized relationships with their end users. The key product from which the segment derives its revenue is Segment.
The Company’s CEO, who is also the CODM, reviews the operating results by segment using non-GAAP income (loss) from operations as the measure of segment profitability. The CODM uses this measure of segment profitability to allocate resources and assess performance of each segment by comparing the segment actual results to the comparable results in prior periods and to any internally or externally set expectations. Presented below is the discrete financial information by reportable segment for the years ended December 31, 2024, 2023, and 2022, that reflects management’s current view of the business and that is regularly provided to the CODM. Prior period amounts were reclassified to conform to the current period’s presentation. Asset information is not reviewed by the CODM on a segment basis. Revenue, costs of revenue and operating expenses are generally directly attributable to each segment. Certain costs of revenue and operating expenses are allocated based on methodologies that best reflect the patterns of consumption of these costs. Corporate costs are not allocated to operating segments. Corporate costs consist of costs that support company-wide processes, are managed on the company-wide level, and include costs related to corporate governance and communication, global brand awareness, information security, and certain legal, human resources, finance and accounting expenses. In addition to corporate costs, cost of revenue and operating expenses not allocated to operating segments include stock-based compensation, amortization of acquired intangibles, payroll taxes related to stock-based compensation, charitable contributions and restructuring costs.
