Magnite exceeded Q1 2025 guidance, with CTV contribution ex-TAC up 15% and DV+ up 9%; adjusted EBITDA grew 47% YoY to $37M (25% margin).
The company launched the next generation of SpringServe, a unified ad server and SSP platform for CTV, set for general availability in July, aiming to further differentiate Magnite in the market.
Magnite is optimistic about potential market share gains from the Google antitrust ruling; every 100 bps of market share gained in DV+ could add ~$50M in contribution ex-TAC, with over 90% flow-through to EBITDA and free cash flow.
Q2 guidance: contribution ex-TAC expected between $154M–$160M, CTV $70M–$72M, DV+ $84M–$88M, and adjusted EBITDA margin of 29% at the midpoint; full-year guidance not reaffirmed due to macro/tariff uncertainty.
The company continues to invest in AI-driven products, cost efficiencies, and curation capabilities, and expects Netflix to be one of its largest CTV clients by year-end; no significant macro-driven ad spend pullback seen yet, but guidance remains cautious.
