Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 27.9% year-over-year (YoY) to $358.0 million. Approximately 56% of the revenue increase was driven by new customers, while 44% came from existing customer expansion.
• Profitability: The company achieved operating income of $1.7 million, a significant improvement from an operating loss of $23.8 million in Q1 2025. Net income turned positive at $9.0 million compared to a net loss of $14.1 million in the prior year.
• Cost of Revenue: Increased 31.6% YoY to $89.1 million, primarily due to a $11.7 million increase in outbound communication sending costs (text/WhatsApp) and higher personnel expenses.
• Share Repurchases: In March 2026, the Board authorized a $500 million share repurchase program. The company immediately entered an Accelerated Share Repurchase (ASR) agreement, paying $100 million and receiving 4.3 million shares.
• Customer Metrics: Customers generating over $50,000 in Annual Recurring Revenue (ARR) grew 38% YoY to 4,175. Dollar-Based Net Revenue Retention (NRR) increased to 110% from 108%.

Guidance, Outlook, and Risks

• Outlook: Management expects revenue growth to decelerate over time as the business matures. Gross margins are expected to decline modestly in the near term due to the higher cost structure of text messaging and WhatsApp channels, though this may be offset by scale efficiencies.
• Strategic Focus: Continued investment in AI capabilities (Marketing Agent, Customer Agent), international expansion (new offices in Canada, Singapore, France), and moving up-market to enterprise customers.
• Key Risks:
  • Third-Party Dependencies: Significant reliance on Shopify integrations (approx. 78% of ARR derived from Shopify customers as of Dec 2025). Disruptions to this relationship could materially harm the business.
  • Regulatory Environment: Evolving data privacy laws (GDPR, CCPA, EU Data Act) and AI regulations (EU AI Act, Colorado AI Act) may increase compliance costs and operational complexity.
  • Cybersecurity: The company disclosed two unauthorized access incidents (Oct 2024 and April 2026) involving source code and credentials, highlighting ongoing security risks.
  • Seasonality: Results are typically stronger in Q4 due to holiday shopping; Q1 is historically weaker.

Investor Verification Checklist

• Verify the sustainability of the 27.9% revenue growth rate given the company's maturation and the shift toward higher-cost communication channels (text/WhatsApp).
• Monitor the status and settlement of the $100 million Accelerated Share Repurchase (ASR) agreement and the impact on share count.
• Assess the long-term stability of the strategic partnership with Shopify and any potential changes to integration terms or revenue sharing.
• Review the company's remediation efforts and security posture following the disclosed cybersecurity incidents in late 2024 and April 2026.
• Track the adoption rate of new AI features (Marketing Agent, Customer Agent) and their contribution to revenue expansion and NRR.
