Magnite reported third-quarter 2025 revenue of $179.5 million, an 11% increase year-over-year that surpassed consensus estimates and exceeded the company’s own guidance. This growth was broad-based across digital TV (DTV) and connected TV (CTV) advertising, reflecting sustained demand from brand advertisers and programmatic buyers. Gross profit margin improved by 120 basis points versus Q3 2024, driven by higher take rates in key markets and ongoing platform optimizations.

The CTV business delivered 25% year-over-year growth on an ex-TAC and political basis, with DTV also contributing double-digit gains. Magnite secured new supply partnerships with Netflix, Roku and Spotify that expanded video and audio inventory. These agreements added over 150 million monthly active users to the platform, accelerating fill rates and driving a 30% increase in auction monetization. Client retention exceeded 95%, underscoring the stickiness of Magnite’s infrastructure solutions.

Management highlighted progress in integrating machine-learning tools for yield optimization and fraud detection, which reduced operating expenses by 8% year-over-year. These efficiencies translated into a 200-basis-point expansion in adjusted EBITDA margin for Q3. Looking ahead, AI-driven bid shading and dynamic floor pricing are expected to unlock further cost savings, supporting management’s target of reaching mid-20s percent EBITDA margin by year-end 2026.

Analysts forecast 19.2% EPS growth for fiscal 2026, reflecting continued revenue gains and operating leverage. At a PEG ratio of 0.66, Magnite trades at a meaningful discount to peers in the ad tech space despite its double-digit growth profile. Key catalysts for upside include deeper monetization of Netflix inventory, resilience to supply-path optimization threats and expansion into Latin American and APAC markets, where CTV penetration remains in early innings.
