Key Financial Metrics

Note: Free Cash Flow is defined by management as operating cash flow less capitalized software development costs and purchases of long-lived assets.

Material Changes vs. Prior Period

• Revenue Growth: Driven by a 20% year-over-year increase, primarily due to higher usage from existing customers (Dollar-Based Net Expansion Rate of 114%) and $70.9 million from new customer accounts. An additional $46.1 million in revenue was generated from incremental A2P (Application-to-Person) messaging fees passed through from U.S. carriers.
• Cost of Revenue: Increased 22% to $722.7 million, largely due to a $118.1 million rise in network service provider costs, including the aforementioned A2P fees. While these fees increase revenue and costs equally (neutral to gross profit dollars), they create a headwind to gross margin percentage.
• Operating Expenses: Total operating expenses rose 3% to $576.6 million. Research and Development increased 3%, while Sales and Marketing remained flat. General and Administrative expenses increased 11%.
• Share Repurchases: The company repurchased 2.1 million shares for $253.4 million in Q1 2026, compared to 1.2 million shares for $130.2 million in Q1 2025. Approximately $892.0 million remains available under the $2.0 billion program authorized in January 2025.
• Equity Method Investment: The company recorded a $27.2 million share of losses from its equity method investment (Syniverse), compared to $19.5 million in the prior year.

Guidance, Outlook, and Risks

• Outlook: Management expects to continue driving profitable growth through product innovation, AI integration, and operational efficiency. They anticipate a reasonable possibility of releasing a significant portion of the valuation allowance on U.S. deferred tax assets in 2026, which would result in a significant income tax benefit, though timing is uncertain.
• Key Risks:
  • Network Fees: Continued increases in A2P messaging fees from U.S. carriers may pressure gross margins.
  • Macroeconomics: Usage-based revenue is sensitive to consumer spending and economic conditions.
  • Regulatory & Tax: Ongoing IRS audit of the 2023 tax return; evolving global data privacy and AI regulations; potential changes in tax laws (e.g., OECD Pillar Two).
  • Cybersecurity: Risks of data breaches and reliance on third-party infrastructure (AWS).
• Unusual Items: In March 2026, the company paid $141.0 million for the 2025 company-wide bonus program, impacting operating cash flow. The company also discontinued the disclosure of "Active Customer Accounts" as a key metric, refining the definition of Dollar-Based Net Expansion Rate.

Investor Verification Checklist

• Margin Sustainability: Verify the trajectory of gross margins given the pass-through nature of rising A2P fees and the mix of international vs. domestic messaging.
• Valuation Allowance Release: Monitor future filings for confirmation on the timing and magnitude of the potential release of the U.S. deferred tax asset valuation allowance.
• Customer Concentration: Confirm that no single customer accounts for more than 10% of revenue or gross accounts receivable (filing states none do).
• Share Repurchase Pace: Assess the remaining $892 million authorization against current cash burn and free cash flow generation to gauge future buyback capacity.
• Equity Method Losses: Review the performance of the Syniverse investment, which contributed $27.2 million in losses to the quarter.
