SUMMARY

Magnite (MGNI 1.54%) reported revenue and contribution ex-TAC above guidance, highlighting momentum in CTV and early stabilization in DV plus as the company continues to gain share among leading publishers and commerce media partners. Management detailed persistent operating leverage from cloud and AI-driven efficiencies, supported by a record EBITDA margin, and outlined near-term plans to accelerate capital returns through aggressive share repurchases in the wake of significant debt repayment. Guidance for Q2 and full year 2026 points to sustained top-line growth, margin improvement, and robust cash generation, with CTV scaling as the central driver and management raising its free cash flow growth outlook to the mid-30% range. The CEO characterized SpringServe as the core infrastructure behind the company’s channel leadership, while also sharing broad-based CTV demand from partners such as LG Ads, Netflix, and VIZIO Walmart, and emphasizing the durability of recent operational savings linked to ongoing cloud optimization and further AI initiatives. Strategic priorities remain focused on capturing commerce media and live sports opportunities, as well as driving international expansion through OEMs and streamer growth, with management reaffirming that projected results exclude any benefit from potential Google AdTech remedies.

  • CEO Barrett stated, "We are increasingly the single entry point for buyers to access premium CTV inventory at scale, becoming the easy button for CTV."
  • Management indicated no current increase in cash tax liability is expected despite profitability growth, helping maintain flexibility for capital returns.
  • Day said, "We have more to come on that front as we bring a new data center in Northern California online later in the year," referencing further expected margin expansion.
  • Company confirmed business mix shift continues, with CTV consistently above 50% of total contribution ex-TAC and DV plus seen as a stable, but slower-growth, portfolio.
  • Management noted, "The OpenPath extinction event has come and gone, and we are still here and doing quite well," signaling competitive positioning post-industry disruption.
  • Capital allocation strategy targets returning approximately 50% of free cash flow to shareholders through buybacks, supported by ongoing free cash flow growth outlook.
  • Live sports highlighted as an underpenetrated programmatic growth area, with global sports events such as March Madness and the Summer World Cup set to increase streaming volumes and inventory scale.
  • Integration of AI across workflows is framed as a key driver for margin improvement and process automation, with management stating "AI is increasing efficiency, expanding working media, and driving more volume."

I encourage you to visit our Investor Relations website to access our press release, financial highlights deck, periodic SEC reports, and the webcast replay of today's call to learn more about Magnite, Inc. I will now turn the call over to Michael. Please go ahead, Michael.

Michael Barrett: Thank you, Nick. Thanks, everyone, for joining us today. We delivered a strong first quarter, exceeding expectations across both revenue and profitability. Top line came in ahead of consensus with DV plus outperforming our guide, and CTV in line. Adjusted EBITDA exceeded consensus by $5 million, driven by earlier-than-expected cost efficiencies, and we are encouraged by the margin expansion we are seeing. Importantly, the broader market trend remains unchanged. Ad dollars continue to shift towards streaming. In Q1, CTV contribution ex-TAC grew 30% and represented 51% of total, maintaining the momentum we saw in 2025. That strength was broad-based. We saw continued growth across leading publishers, including LG Ads, Netflix, Paramount, Roku, VIZIO Walmart, and Warner Bros. Discovery.

Our top 10 accounts grew in the mid-30% range year over year, with the rest of the base growing in the mid-20s. This is not isolated performance. It reflects a platform that is gaining share as the market scales. The acceleration we are seeing in CTV is not surprising. We are materially outpacing the market and we believe that is sustainable. This is driven by both new wins and expanding partnerships, but more fundamentally, by SpringServe. SpringServe has evolved from a best-in-class ad server into the operating system for CTV monetization. We sit at the center of the transaction, unifying demand, optimizing yield, managing ad experience, and orchestrating data across the workflow.

There are point solutions in the market, but no other scaled platform in CTV combines ad serving, mediation, and monetization infrastructure in a single unified layer. For publishers, this drives higher yield and better control. For buyers, it provides a direct path to the broadest set of premium inventory. And this capability scales across every cohort we serve. We support OEM monetization across home screens and emerging formats, partner with streamers to build and support their offering, and help broadcasters optimize their sales efforts, particularly as live and SMB demand grows. And in live TV, where performance requirements are highest, our differentiation is even more pronounced. Live sports remains one of the largest and least penetrated opportunities in programmatic.

We are seeing strong traction here, including more than 80% growth year over year in revenue from March Madness. On the demand side, buyer marketplaces are scaling, ClearLine adoption is increasing, and buyers are prioritizing more direct and efficient access to premium CTV supply. We are also seeing commerce media emerge as an important driver across both DV plus and CTV. These partners are bringing valuable first-party data and incremental demand into the ecosystem, increasingly activating across streaming environments. Our recent announcements with Expedia Group, Walmart Connect, and Roku Curate show further traction on the commerce media front. Across all of these areas, our role is consistent. We are the infrastructure layer that connects the ecosystem.

As our capabilities expand, so does our position. We are increasingly the single entry point for buyers to access premium CTV inventory at scale, becoming the easy button for CTV. And as the market consolidates around scaled platforms, we believe our lead is durable and widening. Turning to DV plus, DV plus declined 5% in Q1, which was better than expected. While budget shifts toward CTV continue, we remain confident in the long-term role of DV plus. Trends improved exiting Q1 and into Q2 with signs of stabilization driven by mobile and app, online video, audio, and commerce media.

Mobile and app grew 8% year over year and remains a durable growth segment supported by deeper integrations and new publisher and DSP onboarding. Commerce media continues to build momentum, with 21 partners and 13 now deployed and ramping, expanding both our demand footprint and data capabilities across DV plus and CTV. On the Google AdTech remedies, our view remains unchanged, and we continue to believe the potential upside is meaningful. Stepping back, what ties this together is how our platform is evolving, particularly with AI. We are embedding AI across the platform to improve how media is bought and sold.

At the core, AI enhances how inventory is valued, how campaigns are executed, and how decisions are made in real time. For publishers, AI is improving monetization through dynamic pricing and demand optimization. And with ClearLine, AI is simplifying activation, curation, and optimization, reducing friction and enabling faster execution. Across the platform, we are beginning to see the emergence of agentic work, enabling greater automation and efficiency for both buyers and sellers. What matters is not a single feature; it is how these capabilities work together across our scaled infrastructure. We are already seeing adoption from the leading players across the ecosystem, using our AI to automate workflows, act on real-time signals, and improve performance.

This is still early, but the direction is clear. AI is increasing efficiency, expanding working media, and driving more volume through platforms like ours. This is a tailwind for Magnite, Inc. Before I conclude, I want to address David's retirement. As previously announced, David has decided to retire after more than thirteen years of exceptional service. He has been an invaluable partner and a steady leader whose financial stewardship helped shape Magnite, Inc. into the company we are today. We are grateful for his leadership and for his commitment to ensuring a smooth transition, as he remains in his role through September 30 while we evaluate internal and external candidates.

On behalf of the board and the entire Magnite, Inc. family, I want to thank David and wish him and his family all the best. With that, I will turn the call over to David for more details on the financials.

David Day: Thanks for those kind words, Michael. I appreciate it. We are off to a good start to 2026. Q1 total contribution ex-TAC grew 10% and came in at the top end of our guidance range. As Michael mentioned, CTV increased an impressive 30% year over year, and DV plus declined 5% but exceeded our previous expectations. We are pleased with the results and are encouraged by the many positive catalysts that are driving momentum in our business. Total revenue for Q1 was $164 million, up 6% from Q1 2025. Contribution ex-TAC was $161 million, up 10% at the high end of our guidance range. CTV contribution ex-TAC was $82 million, up 30% year over year.

DV plus contribution ex-TAC was $79 million, a decrease of 5% from the first quarter last year. Our contribution ex-TAC mix for Q1 was 51% CTV, 34% mobile, and 15% desktop. From an overall vertical perspective, health and fitness, retail, and food and beverage were the strongest performing categories, while automotive and technology were our weakest performing categories. Total operating expenses, which include cost of revenue, were $157 million, flat from last year. Adjusted EBITDA operating expense for the first quarter was $118 million, $4 million better than our guide, and an increase from $109 million in the same period last year.

Operating expense was better than expected due to significant improvements in cloud spend and some early AI-related productivity gains. Our net income was $4 million for the quarter, compared to a net loss of $10 million for 2025. Adjusted EBITDA grew 16% year over year to $43 million, reflecting a margin of 27% as compared to 25% in Q1 last year. As a reminder, the first quarter is always seasonally our lowest margin quarter. We calculate Adjusted EBITDA margin as a percentage of contribution ex-TAC. GAAP earnings per diluted share were $0.03 for 2026, compared to a net loss of $0.07 for 2025. Non-GAAP earnings per share for 2026 were $0.13, compared to $0.02 in Q1 last year.

The reconciliations to non-GAAP income and non-GAAP earnings per share are included with our Q1 results press release. Our cash balance at the end of Q1 was $185 million, a decrease from $553 million at the end of the fourth quarter. The drivers of the change were the $250 million payoff of our convertible debt, planned capital expenditures, share repurchases, and normal seasonality in working capital. Operating cash flow, which we define as Adjusted EBITDA less CapEx, was $23 million. Capital expenditures, including both purchases of property and equipment and capitalized internal-use software development costs, were $20 million, in line with the expectations we discussed last quarter. Net interest expense for the quarter was $5 million.

Net leverage was 0.7x at quarter end, consistent with our target of less than 1x. During the first quarter, we repurchased or withheld over 2.2 million shares for approximately $29 million. As of quarter end, $186 million remained available under our current repurchase authorization, which is effective through February 2028. Now that we repaid our convert, we plan to be more aggressive with share repurchases given our expected free cash flow generation. As discussed last quarter, our capital allocation strategy aims to return approximately 50% of free cash flow to shareholders via share repurchases. We believe our shares currently trade at very attractive levels.

For the second quarter, we expect contribution ex-TAC to be in the range of $177 million to $181 million, which represents growth of 9% to 12%; contribution ex-TAC attributable to CTV to be in a range of $90 million to $92 million, which represents growth of 26% to 29%; DV plus contribution ex-TAC to be in the range of $87 million to $89 million, which represents a decline of 4% to 2%. We anticipate Adjusted EBITDA operating expenses to be in the range of $115 million to $117 million, which implies Adjusted EBITDA margin of 34% to 36%.

And for the full year 2026, we reaffirm total contribution ex-TAC growth to be at least 11%, reaffirm Adjusted EBITDA percentage growth in the mid-teens, raise Adjusted EBITDA margin to be at least 35.5% from greater than 35%, raise free cash flow growth to be in the mid-30% range from greater than 30%, and reaffirm CapEx of approximately $60 million, a reduction from prior year. I want to point out that our estimates do not include any potential market share gains as a result of remedies from the Google AdTech trial. Lastly, a note regarding our tax position. We would not expect to have any significant increases in cash taxes.

Finally, on a personal note, I am incredibly pleased with our performance and the robust financial position the company maintains today. It is from this position of strength that I have decided to retire, marking the end of what has been the most rewarding chapter of my professional life. My journey here from the early days of Rubicon Project through our 2014 IPO, transformative merger with Telaria, and the acquisitions of SpotX and SpringServe has been an exhilarating ride. I am immensely proud of the durable company we have built, our winning culture, and a world-class finance team.

While I am looking forward to spending more time with my family, I will continue to energetically serve as CFO through September 30 to ensure our momentum continues uninterrupted and to assist Michael and the board in identifying my successor. I leave with full confidence that Magnite, Inc. is extremely well positioned to lead the future of digital advertising. Thank you all for an unforgettable decade-plus partnership. We will now open the call for questions.

Operator: We will now open the call for questions. To ask a question, you may press star, then 1 on your touch-tone phone. If you are using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star, then 2. We ask that you please limit yourself to one question and one follow-up. If you have additional questions, please rejoin the question queue. The first question today comes from Daniel Louis Kurnos with Stifel. Please go ahead.

Daniel Louis Kurnos: Great, thanks. Good afternoon, and let me be the first, David, to wish you the best. It has been a pleasure working with you. Michael, let me jump in and unpack DV plus a little bit for a second. Your comments suggest that we are still seeing mix shift to CTV, but your guide suggests, I mean, you talked about stabilization, your guide is almost flat in 2Q. I am just trying to figure out how much of that is these commerce media wins backing up here, and how you think that might trend as we proceed through the year, understanding there is uncertainty in the macro and the pressures that we are still seeing in the traditional desktop business?

Michael Barrett: Yeah, Dan. I noticed you did not say it was a pleasure to work with me, so that is kind of hurting. But, yeah, good observation. We do think we have seen stabilization to DV plus, driven largely by the open web—display certainly under siege—but other pockets, mobile app, commerce media, as you pointed out, audio, are growth areas for us. I do think macro weighs heavy on DV plus particularly, but seeing it return to flattish is something that I think would still outperform the market, and that is kind of where I think we should be in either one of our businesses.

Daniel Louis Kurnos: I promise you, Michael, when you eventually someday down the line retire, I will say very nice things about you. The other thing that I wanted to ask about, just quickly, since you brought up live sports and some of the drivers there. Obviously, we have a very big event coming up, the Summer World Cup. We are kind of a month out now. We are starting to see a little bit more of what FOX's strategy is there, and we are finally going to get real games on Tubi. They have DTC out there now. So just curious how we should be thinking about the impact of that event.

And it seems like every time we get one of these big events, even starting with Olympics this year, and you mentioned March Madness, more and more inventory shifts to programmatic. So I do not know if you think that is also an incremental catalyst for more inventory to keep moving in that direction.

Michael Barrett: Yeah, it will certainly be a good guide for us. And I do think, given the volume of games and some of the added ad breaks—for instance, the mandatory water breaks—that is going to be a big ad load there. So we are expecting good things from it. Not so sure it will be something that we will be citing as a comp issue in 2027, but it will certainly be part of the portfolio of the sports that is going to add to the revenue growth.

Operator: The next question comes from Shyam Vasant Patil with Susquehanna. Please go ahead.

Shyam Vasant Patil: Hey, guys. Congrats on the results, and David, on your retirement as well. I had a couple of questions. First, David, in your remarks, you talked a little bit—almost a side comment—about an uncertain macro. Did this have any impact on you guys in 1Q or 2Q? Obviously very strong results, but would they have been even better if it were not for some of the macro events? And then second, Michael, strong CTV growth and outlook as well. Is there any reason to think that CTV cannot continue to grow at these levels going forward on a secular level? And then related, how are you thinking about the secular profile for desktop and mobile? Thank you.

David Day: Great. On the macro front, it certainly was not an overwhelming drag on the quarter. But you see it in a couple of verticals in particular—automotive, most importantly, and that is a large vertical, and that was down significantly; technology also. So you see some impacts. There is still some overhang from tariff challenges, supply chain challenges, and then just uncertainty with things in the Mideast. Those are the data points underlying my comment. It is not booming, but we are not prognosticating doom and gloom either.

Michael Barrett: Yes, Shyam, and on the CTV front, we are really pleased with the growth rates and feel very strongly that they are sustainable. The market as a whole, from peer reports and analyst expectations, looks like it is growing in the low teens. So we are significantly outperforming market growth, and that has been a stated goal of ours. I think that will continue given the penetration we have with all the top streamers, their growth profiles, and increasing wins across the globe. It is pretty much an untold story for us, the success of these streamers that are U.S.-based—when they go international, we go with them.

And then they have the added benefit of disrupting the local market, and those markets are forced to adopt programmatic and streaming. So it is a real positive story for us internationally. As far as DV plus is concerned, that is a difficult one because it is a portfolio. But in terms of the high-growth areas, in-app mobile is a huge growth category, audio is a very promising growth category, and even digital out-of-home—you see all the outdoor companies report how fast that is growing. We think that DV plus as a whole is an important part of the business and will be a positive contributor. It is just hard to swag it on a specific basis going forward.

Operator: The next question comes from Jason Michael Kreyer with Craig-Hallum. Please go ahead.

Jason Michael Kreyer: Great, thank you. Michael, I wanted to ask on AI. You have brought some new solutions to market in the last several weeks. Can you talk about demand and adoption trends of AI-enabled tools? And maybe give perspective on what pain points exist in the industry that you can leverage AI to make more efficient?

Michael Barrett: Great question, Jason. Wow, no love for David. AI in 2026 will be the story of AI with modest amounts of revenue flowing through. There are several working initiatives, several different standards out there. A lot of it is replacing direct-sold—not even truly real-time programmatic—but bringing more dollars into the programmatic ecosystem because it is so much easier to do it agentically. I think the biggest benefit you are going to see from it is workflow and productivity, because these are easier to use. Instead of toggling between 13 different dashboards, you can, in natural language, ask the agent to perform a task. It will free up a lot of bandwidth for the traders. It will be more efficient.

There will be more working media going to it. We are exceptionally well positioned from the tools we have built and are building to be able to catch it when the dollars start to flow. I would imagine 2027 will be the year where AI actually results in real revenue, and I think we are really well positioned to take advantage of that.

Jason Michael Kreyer: Thank you. And David gets his own question. David, congratulations on your retirement. It has been my pleasure working with you for most of that thirteen years. I wanted to touch on the EBITDA OpEx that came in better in Q1. You are guiding for that to be better for Q2, and you outlined the cloud and AI benefits. How durable are those savings? And do you think there is more to squeeze out as we move forward?

David Day: I think, as a general matter, the savings are very durable. The primary drivers are twofold: moving some of our activity from the cloud to on-prem, and our dev team is doing a great job optimizing how we run more efficiently in the cloud. Now, that said, we do have some resources going into product development later in the year. We have a lot of new business and volume increases. I would not go too crazy with lowering costs, but the trend line is definitely durable. We have more to come on that front as we bring a new data center in Northern California online later in the year.

There is lots of opportunity, particularly as we spring into 2027, on the margin expansion front.

Operator: The next question comes from Laura Anne Martin with Needham. Please go ahead.

Laura Anne Martin: Hey. I have two. One is Taboola said on their call this morning that they see programmatic workflows being replaced by agentic. You just mentioned that you thought it might be additive, but why do we not have agentic buy-side agents talking directly to agentic sell-side agents in the ad business and therefore getting rid of most of the 40% to 50% take rate that currently sits in the open web programmatic ecosystem? That is my first question. And then my second question is on pricing power. One of the things that came out of Possible is everybody is introducing AI products; nobody is charging for them.

They are all just table stakes and making everybody’s products more interesting, more automated, and higher return on ad spend. Are we actually going to get price uplift by all these AI innovations, or is it just going to become table stakes and we spend money in AI but do not get any revenue upside? Thanks.

Michael Barrett: Hi, Laura. I will grab the first one. There has certainly been an overhang for a lot of software companies about agentic replacing the need for those companies. We feel—as we said in our previous quarter script and this one—that AI is a real tailwind for us. It makes things easier to work with. It lets our publishers go from a dozen dashboards—SpringServe, DV plus—to one, and they can execute more seamlessly. The agent-to-buyer connection makes a ton of sense, but who is to say that the buyer agent is not ours that they are utilizing, just like they utilize ClearLine? I think there is real upside there.

But also, if you want to conduct conversations, execute plans, and buy programmatically from tens of thousands of buyer agents, that is where we really shine. We make sure those are the agents you want to talk to, that it is brand-safe inventory, we are collecting payment, and we are policing fraud. Our plumbing—our bandwidth, our servers—are all being utilized to make it happen. We feel it is going to be more volume on the platform than we have ever seen, and yes, we will charge for that, and it will improve our margin profiles, not be a pressure on it.

David Day: I think Michael hit it. Particularly in CTV where we do have lower take rates at the moment, those are stabilizing. There is so much value-add; as we provide additional value-added services, we only see those increasing in the future. That value-add will be accelerated with the AI implementations we are making.

Operator: The next question comes from Analyst with B. Riley. Please go ahead.

Analyst: Great, thank you very much. A couple of questions from me, and David, all the best. One question is around commerce media. You have talked about how you have 21 partners, now with 13 deployed. Can you give us a sense of the scale that this business is at currently and how fast it might be growing? And then on live sports, you called it out as a sizable opportunity. Can you talk about penetration levels of live sports with programmatic and where it could be over time? Thank you.

Michael Barrett: Sure. Commerce media is super exciting for us. We mentioned the number of partners, and that total keeps growing. The most important thing about commerce media is not necessarily the number of partners, but how quickly the strategy has changed for the commerce media players. Chapter one of commerce media was: take my valuable retail data, park it in one DSP, and force all the advertisers that want to utilize that data to go through that DSP. Now you are starting to see that unwind, and the strategy now is: keep the data as close to the retail media partner, working with an SSP like Magnite, Inc.

That way you can democratize it and allow multiple DSPs to access it in a safe, privacy-compliant way. That is the most exciting change we are seeing and a huge tailwind for us. As far as contribution, commerce media has been a significant contributor and will expand because a lot of these players are now adding CTV to the inventory mix. They start with their owned and operated inventory, then go off-net—typically in the DV plus world—and now their advertisers are saying, “I do a lot of advertising on TV; I want to do that with your data.” We are the perfect on-ramp for that to occur.

We are really excited about the prospect of further growth with CTV being an essential part of the story for most commerce media partners. On live sports, we are just scratching the surface. As a consumer, you see live sports everywhere in streaming, but programmatically very little inventory is bought and sold programmatically. So when we say gains like 80% plus for March Madness, it is minuscule compared to the opportunity that is coming. We are super excited about World Cup and the fall slate of sports. Little by little, it is getting more programmatically driven, and it is a big tailwind for us.

Operator: The next question comes from Kenneth Andrew Wu with Wolfe Research, on behalf of Shweta Khajuria. Please go ahead.

Kenneth Andrew Wu: Hi, this is Ken on for Shweta. Congrats, David, on the retirement. Two for me. Michael, can you provide an update on the impact of OpenPath, particularly with smaller advertisers and agencies? And David, can you provide the puts and takes of EBITDA in 2026? Thank you.

Michael Barrett: On OpenPath, I think we have talked about it ad nauseam. It came as a shock to the system a couple of quarters ago. We stated that all the big buyers from the agencies that use Magnite, Inc. as an invaluable partner had flipped it back on. You can see in our results that it is certainly not deteriorating. The OpenPath extinction event has come and gone, and we are still here and doing quite well.

David Day: On EBITDA in 2026, we mentioned we expect 11% or greater growth on the top line—stable and steady. On the cost side, we have nice savings with our cloud usage, but we have some volume growth and resources that will neutralize some of that savings this year. As I mentioned, the EBITDA margin is increasing—we expected something north of 35% and expect about 35.5% this year. What is really great is our EBITDA margin is increasing, and it is cost-driven at this point. To the extent we have upside on the revenue line, that upside will flow almost 100% to free cash flow in the business. We are really well positioned.

Operator: The next question comes from Robert James Coolbrith with Evercore ISI. Please go ahead.

Robert James Coolbrith: Good afternoon. Congratulations on a great run to David, and best wishes on your retirement. Michael, you are great too. I want to ask about AI creative generation. Any update on the role you are playing there? We are beginning to see more tools released to general availability. Are you beginning to see more AI-generated creative showing up in the market? Could that catalyze incremental demand or creative refresh, and what does that do for CTV? And then related on AI, we heard speculation about players monetizing AI engine inventory itself. Do you think there is an opportunity for Magnite, Inc. there? Thank you.

Michael Barrett: As you know, we purchased a couple of quarters ago a company called Streamr, one of the leading tools that allows small to medium-sized businesses to create TV ads, track them, measure them, and buy them—obviously on our platform with access to all the premium streamers. That product is really taking off. Our role is not to chase down the SMBs; it is to put those tools in the hands of folks that have those relationships—either large aggregators bringing that demand onto our platform, or publishing partners that hang that as their self-serve. When they have relationships with small advertisers, they use the tool.

It has turned out to be a wonderful acquisition, and we are starting to see the benefits reflected in the growth rates of CTV. On the AI engines themselves, it is very early, but you are seeing that the ones that are ad-supported are reaching out for third-party demand. History is pretty clear: initially, if you are just going to work with one DSP, maybe there is not a need for someone like Magnite, Inc. But when you start to work with three, four, five, six, seven—and globally—with specialty DSPs, we feel very encouraged about the initial direction of folks leaning into third-party demand.

In that case, SSPs become invaluable, and we are well positioned to take advantage when the time is right.

Operator: The next question comes from Barton Evans Crockett with Rosenblatt. Please go ahead.

Barton Evans Crockett: Thanks for taking the questions. Two, if I could. First, to get your perspective on an environment where agencies could be working with a single integrated interface—through Quad or something—to place outcome-driven marketing dollars across environments, whether social walled gardens like Meta, search environments, AI environments like Google Gemini, or open web. In that environment, simplified at the agency front end and built on an LLM, does that have any impact on take rates or revenue flows for you? Is that where it is going?

Michael Barrett: I certainly think that is a worldview a lot of people share—more simplified buying tools for agencies that actually deliver upon the stated goal for the marketer. I think our role remains quite valuable and necessary in that world. We are the system of record—the rails upon which the transactions take place. It is one thing for an agent to talk to another agent, but they are involved in a complex transaction in real time, doing it trillions of times a day. You really need the infrastructure, and that is where we shine. The impact to our take rate—I do not think there is any change in what we do in that world.

It is just probably easier for seller and buyer—fewer interfaces, fewer knobs and tools—perhaps freeing up more working media. Our role remains unchanged as that system of record, so I feel confident in our durability as it relates to take rates.

Barton Evans Crockett: Switching gears, on Google AdTech antitrust—we are sitting here in May, and we still do not have a decision on the remedies. If a remedy decision were to come out today, what is your sense of when you could begin to see the impact? Is it something that is now pushed into 2027? Any thought to how much time it would take to implement, given legal waiting periods and technological considerations?

Michael Barrett: Great question, and I think you hit the nail on the head—it really does depend upon the remedy. Some are behavioral in nature; some would require Google to do technical work to make it happen. Even in their case, they cited a six- to nine-month window for changing two of the things they were talking about. But I definitely think there would be some instant gains. Keep in mind, we see all the inventory, we bring it to auction, and our win rate is very low when it goes up against Google. Therefore, if there was a behavior change, it could be somewhat instantaneous in the impact we would see.

I certainly do not think any of the benefits from the ruling are all pushed out to 2027. Obviously, we are a little disappointed that there has not been a ruling, but I anticipate a favorable ruling for us and impact in 2026.

Operator: The next question comes from Analyst with RBC Capital Markets, on behalf of Matthew John Swanson. Please go ahead.

Analyst: Hey, guys. This is Cameron on for Matt Swanson. Congrats on the quarter, and congrats, David. One for me. Going back to CTV and DV plus, we have been seeing how CTV has been hitting an inflection point for the business. Last quarter, we started talking about the accelerated reallocation of budget from DV plus to CTV. While there are areas of growth in mobile and commerce for DV plus, to what extent does this reallocation remain a headwind? Has that accelerated this quarter, and do you expect it to continue for the year?

Michael Barrett: Great question. I do not know if we have seen an acceleration, and you can see the freshening of DV plus growth rate exceeding our expectation. I think there is stabilization. A big slug of that portfolio is open web display, and I think it is safe to say that will be a negative grower. But could that be outpaced by mobile app, audio, commerce media, digital out-of-home? Certainly. Our long-term expectation for DV plus is it is a grower, but it will not have the profile of a CTV growth rate. Increasingly, our revenue balance will be more CTV than DV plus for the company.

Operator: The next question comes from Analyst with Lake Street Capital Markets. Please go ahead.

Analyst: Hey, thanks for taking my question. Just a quick one. As CTV is now over 50% of total contribution ex-TAC, how should we look at incremental margins on CTV versus DV plus? Is there a mix shift that is structurally lifting margins by itself, or are there some offsetting costs?

David Day: It is generally equal. We do not see headwinds by having a greater proportion of our business be CTV. In fact, as we mentioned earlier, we have significant gains in the cost basis on our CTV business with our cloud costs going down. It will not be one of the more significant drivers—it is more neutral.

Operator: This concludes our question and answer session. I would like to turn the conference back over to Michael Barrett for any closing remarks.

Michael Barrett: Thank you, Operator. CTV's long-awaited ramp in programmatic has clearly arrived, and the investments we have made over the past several years are now translating into profitable, scalable growth. We believe CTV is in a powerful phase of its evolution. The shift to programmatic is real, and as the channel matures, it is increasingly taking share from both linear television and other digital formats. Before we close, I want to thank our team at Magnite, Inc. The progress we discussed today is a direct result of your hard work, innovation, and commitment to our partners. Your efforts continue to position us at the center of this transformation.
