Q&A Highlights

  • Oracle customer conversion: 70% renewal rate on ~75 accounts signed in 2H’24; focused on cross-sell/upsell with strong optimization uptake; continuing to add new Oracle wins .
  • Social Optimization adoption: Number of brands adopting pre-bid Social on Meta more than doubled QoQ; Meta Threads verification test launched with select advertisers, global third-party verification planned in coming months .
  • Publisher growth drivers: OEM/CTV (Publica Vault) adoption and new international wins; continued double-digit growth for IAS Publisher .
  • Segment volatility: Management suggests focusing on annualized trends; Measurement growth doubled to 8% YoY with strong Social; continued shift from Open Web display to Optimization and Social .
  • Optimization economics: Pricing +10% YoY tied to QSP, as last two major DSPs (DV360, Amazon) came online .
  • Guidance composition: For 2H, Measurement high single-digit, Optimization mid-teens, Publisher strong double-digit but normalizing vs tough comps; international growth supported by Social/CTV .

Estimates Context

  • Q2 2025: Revenue $149.204M vs S&P consensus $143.612M (beat); S&P Primary EPS $0.1602 vs $0.04071 (beat). Company GAAP EPS was $0.10 .*
  • Q3 2025: Company guides $148–$150M; S&P revenue consensus is ~$149.18M – broadly in line at the midpoint .*
  • FY 2025: Company raises revenue to $597–$605M and adjusted EBITDA to $208–$214M; S&P revenue consensus ~$609.14M – new midpoint ($601M) is slightly below Street, implying potential for estimate recalibration if momentum persists or if H2 mix improves .*
  • Implication: Street likely revises near-term EPS upward given the magnitude of the Q2 beat and operating leverage, while FY revenue estimates could move closer to company guidance unless product momentum (Social/Optimization/CTV) drives incremental upside.*

*Values retrieved from S&P Global.

Key Takeaways for Investors

  • Quality beat with positive mix: Broad-based growth and strong Social/Optimization traction drove a material top- and bottom-line beat vs S&P consensus; momentum supported by product innovation and platform integrations .*
  • Guidance raised but conservative vs Street on FY revenue: Provides a prudent setup; delivery against Q3/Q4 plus continued product adoption could unlock estimate upgrades and multiple support .*
  • Profitability intact with H2 margin tailwind: Near-term gross margin pressure (infra/optimization mix) expected to ease in H2; operating discipline and rising scale support sustained 30%+ adjusted EBITDA margins .
  • Strategic differentiation strengthening: Ethical AI certification, Threads test, Lyft and Snap partnerships, and QSP ubiquity reinforce IAS’s AI-first, platform-embedded position – a durable competitive moat .
  • Mix shift continues: Open Web measurement is a headwind (-7% YoY), but higher-ROI Optimization and Social are taking share; pricing power evident (+10% optimization CPMs) .
  • Balance sheet flexibility: Debt-free quarter-end and expanded revolver (accordion to at least $550M) support “build/buy/partner” strategy and opportunistic M&A/organic investment .
  • Trading setup: Near-term catalysts include continued Social and QSP adoption, CTV/OEM ramp (Samsung/Publica), and execution vs raised guidance; watch FY guidance vs Street and gross margin trajectories for sentiment inflections .
