Robert Coolbrith's questions to PubMatic (PUBM) leadership • Q2 2025
Question
Robert Coolbrith asked about the specific triggering event for the DSP platform shift in July, the timeline for recovery, and whether CTV inventory was similarly impacted by traffic shaping.
Answer
Co-Founder and CEO Rajeev Goel confirmed a significant increase in the DSP's platform shift activity was observed in July and that traffic shaping optimizations apply across all formats, including video. CFO Steve Pantelick added that the change was abrupt, with the DSP's spend dropping from double-digit growth in June to a negative year-over-year decline in July. He stated that mitigation will take time due to the complexity, and the low end of the Q3 outlook assumes limited effectiveness this quarter.
