Key Financial Performance
CTV contribution ex-TAC Grew 32% year-over-year excluding political factors. This growth was attributed to the accelerating shift towards streaming and broad-based adoption across media owners, agencies, and DSPs.
DV+ contribution ex-TAC Declined 1% year-over-year but grew 4% excluding political factors. The decline was due to budget reallocations from DV+ to CTV as CTV became more measurable and performance-driven.
Adjusted EBITDA Grew 9% year-over-year to $84 million, resulting in a 43% margin. This growth was driven by the strong performance in CTV.
Total revenue for Q4 Increased by 6% year-over-year to $205 million. This growth was supported by the strong performance in CTV.
Net income Increased to $123 million for the quarter compared to $36 million in the same period last year. This was driven by a $90 million one-time tax benefit from the release of the valuation allowance on deferred tax assets.
Cash balance Increased to $553 million at the end of Q4 from $482 million at the end of Q3. This increase was due to strong operating cash flow.
Operating cash flow Reported at $61 million for the quarter. This was calculated as adjusted EBITDA less CapEx.
Capital expenditures Reported at $23 million for the quarter, consistent with expectations.

Operating Highlights

AI integration: Magnite embedded an advertising context protocol (AdCP) into SpringServe, executing the industry's first agent-to-agent campaign. AI is modernizing the buying experience and increasing throughput across Magnite's infrastructure.
CTV market growth: CTV is now the majority of Magnite's business, with significant adoption by major players like Netflix, Roku, and Walmart. The shift to streaming is structurally advantageous for Magnite due to deeper integrations and stronger publisher relationships.
DV+ market trends: DV+ grew 4% excluding political but is under pressure as budgets shift to CTV. Commerce Media partnerships are gaining momentum with 15 partners, including United Airlines and PayPal.
Financial performance: Q4 contribution ex-TAC was $195 million, up 8% year-over-year. Adjusted EBITDA grew 9% to $84 million, with a 43% margin. Full-year contribution ex-TAC totaled $670 million, a 10% increase year-over-year.
Cost management: Operating expenses were $153 million, slightly down from the previous year. Adjusted EBITDA operating expenses were $111 million, driven by higher cloud and data center costs and personnel expenses for CTV growth.
Share repurchase plan: Announced a new 2-year share repurchase plan worth up to $200 million, targeting 50% of free cash flow for shareholder returns.
Google AdTech trial: Awaiting court's final order, which could create meaningful share reallocation opportunities. Every 1% of market share gained could represent $50 million in incremental contribution ex-TAC annually.

Key Q&A
Q:Can you break down the growth of CTV, specifically how much is from SMBs and by vertical?
A:Michael Barrett stated that they haven't broken it down specifically by SMBs or verticals. However, he highlighted the broad-based growth of 32% in CTV, driven by performance-oriented SMBs, big branded advertisers, and a shift from digital online video and display to CTV. He also mentioned the appeal of CTV's pricing and performance metrics.
Q:Do you think your infrastructure integrations into large CTV performers reduce investment risk in Magnite as a stock?
A:Michael Barrett confirmed that their deep infrastructure integrations and unique tools like ClearLine differentiate them in the CTV space, which is the fastest-growing segment in digital advertising. This differentiation and moat reduce investment risk.
Q:Can you parse out the mix shift to CTV versus organic partner growth and how much is coming from live events?
A:Michael Barrett and David Day explained that live events are an increasing contributor. They noted a shift of $8-9 million from DV+ to CTV in Q1, but parsing out spend shift versus organic growth is challenging as the shift rolls into organic numbers. They emphasized that both allocation shifts and organic growth are driving CTV's outperformance.
Q:What are your comments on margins, take rate, and cost initiatives?
A:David Day mentioned that margins are improving despite additional investments in CTV engineering and tech stack. He noted that margin expansion could have been greater without these investments, but they are setting up for more rapid margin growth in the future.
Q:What is the sustainable growth outlook for CTV and DV+?
A:Michael Barrett expects CTV to grow in the high teens to 20s, exceeding market growth due to secular shifts. DV+ growth is harder to predict due to its diverse portfolio, but any weakness in DV+ is offset by growth in CTV.
Q:What is the status and impact of OpenPath?
A:Michael Barrett stated that OpenPath has been around for years and is not an existential threat. They have successfully addressed concerns with major buyers, and its impact is modest on DV+ performance with no effect on CTV.
Q:What is the client interest in running volumes through AI agents?
A:Michael Barrett noted high interest but low execution in allocating budgets to AI agents. He emphasized that AI will enhance efficiency and alleviate menial tasks, but significant adoption is not expected in the near term.
Q:Is AI adoption more likely in DV+ or CTV?
A:Michael Barrett believes AI adoption will benefit both DV+ and CTV by improving campaign planning, troubleshooting, and efficiency across platforms.
Q:What investments are driving the Q1 OpEx increase?
A:David Day attributed the Q1 OpEx increase to annual personnel raises, employer taxes, off-site events, and investments in CTV engineering and product development.
Q:What is the context protocol, and how does it relate to CloudX?
A:Michael Barrett explained that the context protocol allows agents to communicate and enhances programmatic efficiency. CloudX is a mediation platform for mobile apps, integrated with Magnite, and is not a competitive threat.
Q:What is the base case expectation for the AdTech antitrust case?
A:Michael Barrett expects behavioral remedies rather than structural changes. He believes a more level playing field will benefit Magnite, regardless of the specific outcome.
Q:What has driven the tipping point in CTV growth?
A:Michael Barrett attributed the tipping point to a combination of organic growth, spend shifts from DV+ to CTV, and strong upfront negotiations favoring streaming. He also highlighted deep integrations with top streamers and ad server capabilities.
Q:What is the progress with partnerships and integrations, including Netflix?
A:Michael Barrett mentioned strong contributions from partners like Netflix, LG Ads, Paramount, Roku, and others. Netflix is expected to be a top partner, with significant growth anticipated in 2026.
Q:How will AI impact take rates and the ad tech ecosystem?
A:Michael Barrett believes AI will enhance efficiency without significantly impacting take rates for top DSPs and SSPs like Magnite. He expects smaller intermediaries to face more pressure.
Q:What is the impact of European antitrust remedies on Magnite?
A:Michael Barrett noted that European remedies are not identical to U.S. expectations. While some publishers have adjusted rankings and price floors, the impact is limited and not directly comparable to U.S. remedies.
Q:What are the key vertical trends in CTV, and are there changes in assumptions?
A:Michael Barrett stated that trends from late 2023 are continuing into Q1 2024, with no significant changes in assumptions for verticals.
Q:What is the outlook for Netflix's contribution to Magnite's growth?
A:Michael Barrett expects Netflix to be a top partner, contributing significantly to CTV growth. He anticipates stable take rates and continued growth in contribution ex-TAC.
Q:What is the opportunity with agency marketplaces and ClearLine?
A:Michael Barrett highlighted the success of ClearLine in agency marketplaces, emphasizing its role in building long-term strategic partnerships and contributing to growth.
Q:Review of Unclear Management Responses
A:Management avoided directly answering questions about the specific breakdown of CTV growth by SMBs and verticals, as well as the exact impact of AI adoption on take rates and the ad tech ecosystem. They provided general insights but lacked detailed data or clarity in these areas.
