Question · Q4 2025
Mark Zgutowicz inquired about the sequential decline in scaled advertiser growth despite a year-over-year increase, asking if this met internal expectations and if a lagging revenue effect or inflection is anticipated. He also asked for details on the Q1 ex-TAC margin guidance, specifically if it's driven by a mix shift to higher take-rate publishers or yield improvements. Finally, he asked about the dynamics driving the strong Q4 growth in 'Rest of World' revenue.
Answer
Stephen Walker, CFO, explained that scaled advertiser trends are best viewed year-over-year due to seasonality, as sequential data can be deceptive. He attributed Q1 ex-TAC margin expansion primarily to a positive shift in business mix towards higher-margin areas (e.g., Connexity) and between regions/publishers, rather than increasing yields. He noted that 'Rest of World' growth is faster due to less mature markets offering more growth opportunities, and these geos tend to be higher margin.
