Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.

We enable businesses of all sizes to revolutionize how they engage with their customers by delivering seamless, trusted and personalized customer experiences at scale.

Our leading customer engagement platform comprises communications APIs that enable developers to embed numerous forms of messaging, voice, and email interactions into their customer-facing applications, as well as software products that target specific engagement needs, including our customer data platform, digital engagement centers, marketing campaigns and advanced account security solutions.

We envision a world in which every digital interaction between businesses and their customers is amazing.

By combining our leading communications capabilities, plus rich contextual data, plus generative and predictive AI, we enable businesses of all sizes to revolutionize how they engage with their customers by delivering seamless, trusted and personalized customer experiences at scale.

We offer communications APIs that enable developers to embed numerous forms of messaging, voice, email and video interactions into their customer-facing applications, as well as software products that target specific engagement needs, including our customer data platform, digital engagement centers, marketing campaigns, and user authentication and identity solutions.

This combination of flexible APIs and software solutions helps businesses of all sizes and across numerous industries to benefit from smarter and more streamlined engagement at every step of the customer journey, including reduced customer acquisition costs, lasting loyalty and increased customer value.

Our platform, which combines our highly customizable communications APIs with customer data management capabilities, allows businesses to break down data silos and build a comprehensive single source for their customer data that is organized into unique profiles that are easily accessible by all their business teams.

Empowered with this information and the insights it enables, businesses using our platform can provide robust, personalized and effective communications to their customers at every stage of their customer relationships.

The value proposition of our offerings has become stronger and our

products have become more strategic to our customers as more and more businesses have prioritized building more personalized and more differentiated customer engagement experiences through digital channels.

In February 2023, we began operating our business in two business units:

Communications and Data & Applications, which has since been renamed Segment.

Our Communications business consists of a variety of APIs and software solutions to optimize communications between our customers and their end users.

Our key Communications offerings include Messaging, Voice, Email, Flex, Marketing Campaigns, and User Identity and Authentication.

Our Segment business consists of software products that enable businesses to leverage their first-party data to create unique customer profiles and achieve more effective customer engagement.

Our key Segment offerings are Segment and Engage.

Together, our Communications and Segment products power our customer engagement platform.

We believe that our two business units are complementary and address adjacent needs and related problems for our customers.

Our goal is to create a flywheel for effective customer engagement by combining Segment’s user profiles with our rich Communications data to drive more personalized and intelligent customer interactions.

We believe that our business unit structure enables each business unit to execute toward its respective goals with appropriate focus and independence, best positioning us to achieve our long-term plan of creating the leading customer engagement platform.

Our platform, which combines our highly customizable communications APIs with customer data management capabilities and AI-powered predictions and recommendations, allows businesses to break down data silos and build a comprehensive single source for their customer data that is organized into unique profiles that are easily accessible by all their business teams.

The value proposition of our offerings has become stronger and our products have become more strategic to our customers as businesses are increasingly prioritizing building more personalized and differentiated customer engagement experiences through digital channels.

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.

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

In the years ended December 31, 2023, 2022, and 2021, our revenue was $4.2 billion, $3.8 billion and $2.8 billion, respectively, and our net loss was $1.0 billion, $1.3 billion and $949.9 million, respectively.

In the years ended December 31, 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.

Recent Developments

Business Unit Reorganization.

In February 2023, we began operating our business in two business units:

Twilio Communications (“Communications”) and Twilio Data & Applications (“Data & Applications”).

We determined that as of the end of the second quarter of 2023 we had two operating and reportable segments, Communications and Data & Applications, and that our segment measure of profitability was non-GAAP gross profit.

In the fourth quarter of 2023, we further modified the organization of our business units by moving our Flex and Marketing Campaigns products from the Data & Applications reportable segment into the Communications reportable segment.

We also renamed our Data & Applications segment to Segment.

The fourth quarter reorganization did not change our reportable segment structure;

however, it changed the reporting unit structure within our operating segments.

Reporting units are the level below the operating segment level at which we allocate and test goodwill.

As a result of these changes, we reallocated goodwill to the newly formed reporting units after each reorganization.

We were required to test goodwill for impairment immediately before and immediately after each time our reporting unit structure changed.

In the second quarter of 2023, we performed a goodwill impairment assessment immediately before and immediately after the reorganization and the change in the reporting unit structure and concluded that goodwill was not impaired.

Prior to testing goodwill in the fourth quarter of 2023, we identified a change in Segment’s performance, which indicated that certain intangible assets in our Segment reportable segment may not be recoverable.

We performed an impairment assessment, as required by the accounting guidance, and recorded a $285.7 million aggregate impairment loss related to Segment’s developed technology and customer relationship intangible assets.

We engaged an external expert to assist us with the valuation analysis.

The loss is recorded in the impairment of long-lived assets line item of our consolidated financial statements for the year ended December 31, 2023, included elsewhere in this Annual Report on Form 10-K.

After the impairment loss was recorded in the fourth quarter of 2023, we performed a goodwill impairment assessment and concluded that goodwill was not impaired immediately before and immediately after the reorganization and the change in the reporting unit structure.

Further, in January 2024, our newly appointed Chief Executive Officer (“CEO”), who is also our Chief Operating Decision Maker (“CODM”), began reviewing segment operating results using non-GAAP income from operations as the segment measure of profitability.

As such, we have disclosed our segment related information to reflect management’s current view of the business.

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

Share Repurchase Program.

In February 2023, our board of directors authorized a share repurchase program pursuant to which we may repurchase up to $1.0 billion in aggregate value of our common stock until the program expires on December 31, 2024.

Repurchases under this program can be made through open market, private transactions or other means in compliance with applicable federal securities laws and could include repurchases pursuant to Rule 10b5-1 trading plans.

We have discretion in determining the conditions under which shares may be repurchased from time to time.

In the year ended December 31, 2023, we repurchased $672.1 million in aggregate value, or 11.3 million shares, of our common stock under this program.

As of December 31, 2023, approximately $327.9 million of the originally authorized amount remained available for future repurchases.

Workforce Reduction Plans.

In February 2023, we announced a workforce restructuring plan (the “February 2023 Plan”) to eliminate approximately 17% of our workforce.

The execution of the February 2023 Plan was substantially completed in the first quarter of 2023.

In December 2023, we announced another restructuring plan (the “December 2023 Plan”) to further eliminate approximately 5% of our workforce.

In the year ended December 31, 2023, the cumulative restructuring expenses incurred under the February 2023 Plan and December 2023 Plan were $165.7 million and were related to employee severance, benefits, vesting of equity awards and facilitation costs.

The estimated remaining expenses related to both plans are not expected to be significant.

For additional details refer to Note 7 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Sabbatical Program.

In February 2023, we announced that we will be sunsetting our employee sabbatical program that we introduced effective July 1, 2022.

The sabbatical program was intended to provide our tenured employees with a paid leave of four consecutive weeks after every three years of service.

Employees who had accumulated more than three years of service as of the program’s effective date became eligible for their benefit immediately.

As of December 31, 2023, the remaining liability of $5.5 million related to the accumulated benefits for employees who remain eligible under this program until its expiration.

As of December 31, 2022, the accrued sabbatical liability was $30.7 million.

Remote-First Company.

In 2022, we announced our decision to become a remote-first company, allowing our employees the flexibility to work remotely on a permanent basis.

As part of our new operating strategy, we permanently closed several of our offices in 2022 and 2023.

These office closures resulted in an impairment of several long-lived assets, including our operating lease assets, leasehold improvements and property and equipment.

In the year ended December 31, 2023, we recorded a total impairment loss of $34.8 million related to our permanent office closures.

Impairment of Strategic Investment.

In the first quarter of 2023, we recorded a $46.2 million impairment loss associated with one of our investments from 2021 to reduce its carrying amount to fair value.

Divestiture of IoT Assets.

In the second quarter of 2023, we completed the sale of our IoT asset group for a stock consideration of $15.8 million.

The loss on divestiture and related expenses recorded in the year ended December 31, 2023 were not significant.

Divestiture of ValueFirst Business .

In the third quarter of 2023, we completed the sale of our ValueFirst business for a total cash sales price of $45.5 million, or $38.2 million in proceeds, net of cash divested.

In the year ended December 31, 2023, we recorded a $28.8 million loss on divestiture and an additional $3.3 million in related expenses.

For additional details refer to Note 5 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

Factors Affecting Our Results of Operations

We are focused on profitable growth.

To increase revenue and grow market share, we intend to further enhance our ISV relationships, improve our self-service capabilities, cross-sell our products, drive product innovation, expand internationally, and enhance Segment interoperability.

We also intend to optimize our business and take measures to reduce costs, including simplifying our business processes, modernizing our infrastructure, focusing on self-service, leveraging AI, and implementing other initiatives targeted at improving efficiencies in our business.

We are also conducting an operational review of our Segment business, which we expect to complete in March 2024.

We are focused on innovation, profit, and growth.

To increase revenue and grow market share, we intend to drive product innovation, leverage predictive and generative AI, further enhance our ISV, reseller and other partner relationships, improve our self-service capabilities, cross-sell our products, expand internationally, enhance Segment data warehouse interoperability, and reduce time to value for Segment.

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.

Our revenue is primarily derived from usage-based fees, which can lead to variability in our results of operations and at times create differences between our forecasts and actual results.

Our usage-based revenue is also more immediately impacted by changes in consumer spending and macroeconomic conditions than our subscription-based revenue.

Our gross margin is impacted by a number of factors, including the timing and extent of our investments in our operations;

our product mix;

our ability to manage our cloud infrastructure‑related and network service provider fees, including

A2P SMS fees;

the mix of U.S.

revenue compared to international revenue;

We also experience

seasonal trends due to increased consumer activity in the fourth quarter, which may result in lower sequential revenue in the first quarter.

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 SMS fees;

changes in foreign exchange rates;

the timing of amortization of capitalized software development costs and acquired intangibles;

and the extent to which we periodically choose to adjust prices of our products.

Our gross profit is impacted by our product mix.

Our cost of revenue and gross profit are also impacted by changes in hosting fees and network service providers’ fees and our ability to pass these costs through to our customers.

We also experience seasonal trends due to increased consumer activity in the fourth quarter, which may result in lower sequential revenue in the first quarter.

We are winding down our video product and the software component of our Zipwhip business in 2024, which we expect will negatively impact revenue growth rates in 2024.

We are also migrating part of Segment’s architecture to a new infrastructure provider in 2024, which we expect to allow us to recognize greater operational efficiency and scale up new AI-driven products and features.

We expect this migration will take several quarters and result in overlapping expenses with our original and new vendors for much of 2024, which we expect to negatively impact Segment gross margins until we complete the migration.

We expect our recent workforce restructurings and recent office closures will reduce our operating expenses.

We are also modifying our employee compensation program by introducing a new cash bonus program and reducing or eliminating our use of equity compensation for certain employees, which will primarily impact our expenses commencing in the first quarter of 2024.

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.

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.

When presented in this Annual Report on Form 10-K, (i) the number of Active Customer Accounts is rounded down to the nearest thousand, (ii) the number of Communications Active Customer Accounts is rounded down to the nearest thousand, and (iii) the number of Segment Active Customer Accounts is rounded down to the nearest hundred.

We believe that the number of Active Customer Accounts, on an aggregate basis and at the segment level, is an important indicator of the growth of our business, the market acceptance of our platform and future revenue trends.

We believe that use of our platform by customers at or above the $5 per month threshold is a stronger indicator of potential future engagement than trial usage of our platform or usage at levels below $5 per month.

Our business and customer relationships have grown since we began reporting the number of Active Customer Accounts using the above definition, which is anchored to a minimum $5 monthly revenue figure.

We have a large number of Active Customer Accounts with relatively low individual spend that in the aggregate do not drive a significant portion of our revenue.

Due to this dynamic, we believe that the number of Active Customer Accounts, as currently defined, is less informative now as an indicator of the growth of our business and future revenue trends than it has been in prior periods.

In the three years ended December 31, 2024, 2023 and 2022, revenue from Active Customer Accounts represented over 99% of total revenue in each period.

Non-GAAP Financial Measures

We use the following non‑GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes.

We believe that non‑GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance, facilitates period‑to‑period comparisons of results of operations and assists in comparisons with other companies, many of which use similar non‑GAAP financial information to supplement their results of operations reported in accordance with generally accepted accounting principles (“GAAP”).

In 2024, Communications revenue increased by $301.6 million, or 8%, compared to the same period last 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 were divested during 2023.

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.
