Material Changes vs. Prior Period
- Revenue Growth: Q2 2025 revenue increased 6% year-over-year (YoY) to $71.1 million, driven by impressions processed and new revenue streams. YTD revenue grew 1% to $134.9 million.
- Profitability: The company reported a net loss of $5.2 million in Q2 2025, compared to net income of $2.0 million in Q2 2024. The shift was primarily due to a $6.0 million swing in "Other income (expense), net," which included a $4.0 million one-time gain from the Google Privacy Sandbox initiative in 2024 that was not repeated in 2025.
- Operating Expenses: Total operating expenses increased 8% YoY in Q2 to $49.9 million. Sales and marketing expenses rose 9% due to increased personnel and facility costs. Technology and development expenses rose 5% due to headcount increases.
- Cost Efficiency: Despite higher absolute costs, cost of revenue per million impressions decreased approximately 17% in Q2 2025 compared to the prior year.
- Share Repurchases: The company repurchased 3.85 million shares for $43.6 million during the first six months of 2025. As of June 30, 2025, $96.8 million remained available under the repurchase program.
Guidance, Outlook, and Risks
- Outlook: Management expects revenues to be affected by macroeconomic conditions for the remainder of 2025. They anticipate a near-term negative impact from recent platform changes implemented by one of their large DSP buyers, though the magnitude is difficult to predict.
- Operational Highlights: The platform processed approximately 854 billion ad impressions daily in June 2025. Net dollar-based retention rate was 102% for the trailing twelve months ended June 30, 2025.
- Regulatory Risks: Significant risks include evolving data privacy laws (CCPA, GDPR, state-level health data laws) and potential litigation regarding the California Invasion of Privacy Act (CIPA). The company is also monitoring the impact of the "One Big Beautiful Bill Act of 2025" (OBBBA) on tax provisions.
- Market Risks: Exposure to foreign currency fluctuations (specifically USD to INR and GBP) and interest rate changes on variable-rate credit facilities (though no debt is currently drawn).
Investor Verification Checklist
- Revenue Concentration: Verify the impact of the "large DSP buyer" platform changes mentioned in the outlook on future revenue stability.
- One-Time Items: Confirm the exclusion of the $4.0 million Google Privacy Sandbox gain from Q2 2024 when comparing year-over-year profitability.
- Share Buybacks: Monitor the execution of the remaining $96.8 million repurchase authorization and its impact on cash reserves.
- Regulatory Compliance: Assess potential costs associated with new state privacy laws (e.g., California Delete Act) and CIPA litigation risks.
- Working Capital: Review the timing of cash receipts from buyers versus payments to publishers, which significantly impacts operating cash flow volatility.
