Key Q&A

Q:What is the impact of Trade Desk's software change prioritizing OpenPath on Magnite?

A:Trade Desk's software change in late Q3 prioritized OpenPath as a default path for supply, which impacted Magnite. Magnite worked with major buyers, including agency holding companies, to reconnect as a preferred supply path. The impact was projected for Q4, but the bulk of it has already occurred and was limited to DV+. Magnite supports Trade Desk's goal of cleaning up the ecosystem and believes its importance to the buying community will mitigate future headwinds.

Q:How is Magnite's partnership with Amazon progressing?

A:Magnite's partnership with Amazon is strong, with Amazon having a banner year. Magnite benefits from Amazon as both a buyer of inventory and a publisher. The partnership is helping Magnite gain share in DV+ as Amazon expands its DSP.

Q:What is Magnite's approach to the SMB marketplace?

A:Magnite is focusing on enabling DSPs like Mountain to attract SMB dollars through its Streamer product. Magnite does not directly chase SMBs but ensures their spend ends up on its platform. The Streamer acquisition also brings AI capabilities to Magnite's technology.

Q:How does Magnite view its role in an AI-driven, agentic world?

A:Magnite sees its role as increasingly important in audience creation and managing first-party data for large media companies. In an agentic world, where inventory and buyer dollars are more integrated, Magnite believes its access to valuable supply gives it a competitive advantage.

Q:What is Magnite's perspective on live sports inventory in programmatic advertising?

A:Magnite sees accelerating demand for live sports inventory in programmatic advertising, including college football and NFL inventory. While programmatic is in its early stages for live sports, Magnite is optimistic about its product lead and partnerships, such as with Disney, in this area.

Q:What is the status of the Google AdTech case and its potential impact on Magnite?

A:Magnite is encouraged by the DOJ's remedies hearings, which focus on structural and behavioral changes. Magnite believes a fair playing field, whether through structural or behavioral remedies, would be a generational opportunity. The 2026 guidance does not include any potential outcomes from the case.

Q:What factors are included in Magnite's 2026 guidance, and what could drive upside?

A:The 2026 guidance is conservative, considering the macroeconomic environment and excluding potential outcomes from the Google case. Upside could come from midterm elections, Commerce Media deals, and AI initiatives, though their timing is uncertain.

Q:How does Magnite view the impact of lower-cost CTV ad units on its premium inventory?

A:Magnite sees stability in CTV CPM trends and believes premium inventory, supported by first-party data, is differentiated from lower-cost ad units. Magnite does not view this as a threat to its revenues.

Q:Why is Magnite increasing both CapEx and FTEs?

A:Magnite is securing additional data center space and moving more processing on-prem to optimize costs. Simultaneously, it is investing in software engineers and product teams to accelerate initiatives in audience work, live sports, ClearLine, and AI implementation.

Q:What is Magnite's outlook for CTV growth in 2026?

A:Magnite projects at least 11% growth in CTV, including political contributions. Excluding political, growth is expected to be around 9-10%, slightly lower than mid-teens growth in 2025 due to conservatism and DV+ reversion to the mean.

Q:What is Magnite's perspective on behavioral remedies in the Google AdTech case?

A:Magnite believes behavioral remedies, such as unified pricing, could be implemented quickly and have a positive impact on its 2026 P&L, particularly in the second half of the year.

Q:What is the impact of shifting budgets from mobile video to CTV?

A:Magnite sees a continued shift of budgets from mobile video to CTV, particularly from SMBs. While initially cannibalistic, this shift is expected to draw budgets from outside Magnite's ecosystem over time.

Q:How is Magnite's relationship with Netflix progressing?

A:Magnite's relationship with Netflix is strong, particularly in international markets where Netflix has highlighted its programmatic success. Expectations for the partnership are being met.

Q:What is Magnite's view on the issue of reselling in the ad tech ecosystem?

A:Magnite supports efforts to clean up the ecosystem, including addressing reselling. Magnite believes it will benefit from these actions due to its direct publisher relationships and role as a principal in the ecosystem.

Q:How is Magnite strengthening its ties with ad agencies amidst industry changes?

A:Magnite is working closely with ad agencies to help them regain relevance in programmatic space. This includes integrating proprietary data products and providing technological solutions for supply path optimization.

Q:Is Magnite seeing increased publisher RFP activity due to the Google AdTech case?

A:No significant changes in publisher RFP activity have been observed yet, as the structure of the ad tech ecosystem remains unchanged.

Q:Review of Unclear Management Responses

A:Management avoided directly answering questions about the potential impact of the Google AdTech case on 2026 P&L, providing only general optimism without specific details. Additionally, they did not provide clear insights into the timeline or specific features of the Netflix partnership, deferring to Netflix to share those details.
