Current report

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 as of September 30, 2025, we had one operating and reportable segment, which comprised all of the consolidated Company.

Removed paragraphs (14)

Previous report

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 have continued 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.

Previous report

Our Segment reportable segment revenue is derived from Segment products that are subscription-based. For these products we recognize revenue evenly over the contract term.

Previous report

In the three months ended June 30, 2025, Segment revenue increased by $0.3 million, or nearly flat, compared to the same period last year. This increase was primarily attributable to an increase of $4.0 million in revenue derived from our new Segment Active Customer Accounts, partially offset by the decreased usage of our Segment products due to churn and contraction affecting our existing customers, as reflected in our Segment Dollar-Based Net Expansion Rate of 95%.

Previous report

The following table presents the results for non-GAAP income (loss) from operations, as reviewed by our CODM, for each of our Communications and Segment reportable segments for the three months ended June 30, 2025 and 2024:

Previous report

In the three months ended June 30, 2025, Communications non-GAAP income from operations increased by $30.7 million, or 12%, compared to the same period last year. The increase was driven by an increase in Communications revenue of $145.7 million, as described in the Revenue section above, and was partially offset by a $94.5 million increase in network service provider costs, net of the impact of hedging instruments, a $10.5 million increase in hosting fees, which support the growth in usage of our products by our new and existing customers, and a $14.6 million increase in total personnel costs.

Previous report

In the three months ended June 30, 2025, Segment non-GAAP income from operations increased by $21.8 million, or 138%, compared to the same period last year. The increase was driven by a decrease in Segment operating expenses of $20.9 million primarily attributable to a decrease in total personnel costs.

Previous report

In the six months ended June 30, 2025, Segment revenue increased by $0.9 million, or 1%, compared to the same period last year. This increase was primarily attributable to an increase of $9.0 million in revenue derived from our new Segment Active Customer Accounts, partially offset by the decreased usage of our Segment products due to churn and contraction affecting our existing customers, as reflected in our Segment Dollar‑Based Net Expansion Rate of 95%.

Reworded paragraphs (34)

Previous wording

In the three months ended June 30, 2025 and 2024, our revenue was $1.23 billion and $1.08 billion, respectively, and our net income (loss) was $22.4 million and $(31.9) million, respectively. In the three months ended June 30, 2025 and 2024, our 10 largest Active Customer Accounts generated an aggregate of 9% and 10% of our total revenue, respectively.

Current wording

In the three months ended September 30, 2025 and 2024, our revenue was $1.30 billion and $1.13 billion, respectively, and our net income (loss) was $37.2 million and $(9.7) million, respectively. In the three months ended September 30, 2025 and 2024, our 10 largest Active Customer Accounts generated an aggregate of 9% and 10% of our total revenue, respectively.

Previous wording

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 Quarterly Report on Form 10-Q, (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.

Previous wording

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. 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. 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.

Previous wording

We believe that measuring Dollar-Based Net Expansion Rate, on an aggregate basis and at the segment level, provides an important indication of the performance of our efforts to increase revenue from existing customers. Our ability to drive growth and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with existing Active Customer Accounts and to increase their use of the platform. An important way in which we have historically tracked performance in this area is by measuring the Dollar-Based Net Expansion Rate for Active Customer Accounts. Our Dollar-Based Net Expansion Rate increases when such Active Customer Accounts increase their usage of a product, extend their usage of a product to new applications or adopt a new product. Our Dollar-Based Net Expansion Rate decreases when such Active Customer Accounts cease or reduce their usage of a product or when we lower usage prices on a product. As our customers grow their businesses and extend the use of our platform, they sometimes create multiple customer accounts with us for operational or other reasons. As such, when we identify a significant customer organization (defined as a single customer organization generating more than 1% of revenue in a quarterly reporting period) that has created a new Active Customer Account, this new Active Customer Account is tied to, and revenue from this new Active Customer Account is included with, the original Active Customer Account for the purposes of calculating this metric.

Previous wording

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 and Flex. For 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.

Previous wording

Most of our usage-based customers gain access to our platform through our self-service sign-up format, which requires an upfront prepayment via credit card that is drawn down as they use our products. Pricing is generally based on a publicly available, self-serve pricing matrix that generally allows customers to receive tiered discounts as their usage of our products increases. Many of our larger usage-based customers enter into contractual arrangements with us for a period of at least 12 months. These contracts may include negotiated terms and typically include minimum revenue commitments of varying durations. Usage-based customers subject to such contracts are typically invoiced monthly in arrears for products used. In the three months ended June 30, 2025 and 2024, we generated 74% and 71% of our revenue, respectively, from usage-based fees.
