Magnite’s shares rose modestly by 2.9% following Q1 results that delivered mixed outcomes: while CTV growth and margin expansion were encouraging, DV+ continued its decline, tempering investor enthusiasm.

• Total revenue beat expectations, driven by strong growth in CTV, with CTV contribution ex-TAC increasing 30% and representing 51% of total revenue.
• DV+ revenue declined 5%, a deceleration though better than anticipated, reflecting ongoing shifts in ad budgets toward streaming formats.
• Adjusted EBITDA exceeded consensus by $5 million, aided by earlier-than-expected cost efficiencies contributing to margin expansion.
• Top 10 accounts grew by mid-30% year-over-year, while the remaining base grew in the mid-20s, indicating broad-based demand strength.
• AI integration into the platform is advancing automation and efficiency, but its impact remains in early stages.
