Michael Barrett (President and CEO)
Thank you, Nick. What an end to 2025! We exceeded consensus expectations for both the quarter and the full year. In a mixed macro environment, our results reflect the durability of our model and the accelerating shift towards streaming. In Q4, CTV contribution ex-TAC grew 32% ex-political, meaningfully above our guide. That acceleration began in Q3 and strengthened into year-end. As we enter 2026, CTV is now larger than DV+, making streaming the majority of our business. That is a defining moment for Magnite. The long-anticipated ramp of programmatic CTV is no longer emerging. It is underway at scale. Adoption is broad-based across media owners, agencies, and DSPs. We saw strong growth from many of the largest players in the industry, including LG Ads, Netflix, Paramount, Roku, VIZIO, Walmart, and Warner Bros. Discovery.
TV OEMs are leaning aggressively into programmatic across home screens, pause ads, data enablement, and marketplaces. Programmatic enablement in live sports continues to expand across the largest global streamers. On the demand side, the largest global agencies are now driving meaningful volume through buyer marketplaces and DSP-agnostic pipes powered by Magnite. ClearLine activation continues to gain momentum as buyers increasingly seek direct, transparent, and efficient access to premium streaming supply. Stepping back, the industry trajectory is unmistakable. Consumers have moved to streaming. Time spent has already shifted. Advertisers are following, and dollars are now catching up. CTV combines the brand impact of television with the precision and measurability of digital. As inventory has scaled and pricing has normalized, CTV has become accessible to a broader range of advertisers, from global brands to performance marketers to SMBs. For Magnite, this shift is structurally advantageous.
In DV+, we operate in a highly competitive market where we hold mid-single-digit share. In CTV, our share is multiple times higher. As dollars migrate into streaming, they move into a segment where we have deeper integrations, stronger publisher relationships, and differentiated infrastructure. Turning to DV+. DV+ grew 4% ex-political in Q4, modestly below expectations. That pressure has increased in Q1. We observed accelerated budget reallocation from DV+ into CTV across agencies, DSPs, and brands. This trend has intensified in Q1. This makes sense. As CTV becomes more measurable and performance-driven and inventory scales, dollars are naturally consolidating into streaming environments. Within DV+, there are encouraging signs. Our mobile in-app business remains healthy. Commerce media partnerships are gaining momentum, with more than 15 partners announced, 11 of which are deployed and ramping, including United Airlines, PayPal, Pinterest, and Best Buy.
These partnerships combined owned inventory with first-party data layered through ClearLine curation. We do not believe that the decline in search referral traffic is impacting our DV+ business. Our footprint remains diversified across open web, mobile app, online video, audio, and digital out-of-home. In fact, our DV+ supply continues to expand, with ad requests growing over 30% year-over-year in Q4 and at similar rates in Q1. Our DV+ business has never been supply constrained. Turning to AI. There has been speculation that generative AI and agent-based buying could disintermediate infrastructure platforms. We believe what is actually unfolding reinforces the importance of scaled sell-side infrastructure. In Q4, we embedded an Advertising Context Protocol, or AdCP, based seller agent directly into SpringServe and executed what we believe was the industry's first agent-to-agent campaign.
Scope 3 served as the buyer agent on behalf of MiQ, with media running across LG and Warner Bros. Discovery inventory. While still early, this marks an important milestone. It represents the first step toward a future where buyer and seller agents can interpret campaign briefs, intelligently match inventory with audiences, and ultimately transact media in a more automated and efficient fashion. Magnite is uniquely positioned on the sell side. We believe we will be long-term winners in digital advertising, giving our differentiated access to supply, scaled and interoperable data assets, and ability to apply AI across the end-to-end workflow. Layering AI into that ecosystem modernizes the buying experience, streamlining historically manual insertion order processes, matching briefs with audiences and inventory at scale, and enhancing traditional programmatic execution. Even in a world of autonomous agents, infrastructure becomes more critical, not less.
Agents may interpret intent, but they still rely on scaled marketplaces to clear transactions, enforce auction mechanics, ensure compliance, manage fraud prevention, and handle financial settlements. As the ecosystem evolves toward potentially thousands of buyer and seller agents, aggregation and interoperability become essential. You cannot have a market where every agent negotiates bilaterally with every other agent. Standards-based scaled platforms are required to make that system function. That is the role Magnite plays. In Q1, we are continuing to run test campaigns and refine the AdCP framework. It's early, but we are encouraged by the progress and view this as a meaningful step toward a more intelligent and efficient advertising marketplace. AI is not displacing our infrastructure. It is increasing throughput across it. Lastly, on DV+, we continue to await the court's final order in the Google Ad Tech remedies phase.
We believe remedies could create meaningful share reallocation opportunities. As we have stated, every 1% of market share gained could represent approximately $50 million of incremental contribution ex-TAC annually at very high incremental margins. We remain prepared. To conclude, we are in the early innings of a multiyear replatforming of television and video advertising. Streaming is now the dominant form of video consumption. CTV represents the majority of digital video time spent, yet ad dollars still lag engagement. Industry forecasts call for sustained double-digit CTV advertising growth for years to come, with tens of billions of dollars expected to shift from linear television and fragmented digital channels into streaming environments. Magnite sits at the center of that shift. CTV is now the majority of our business. We are deeply integrated with the largest streaming publishers and OEMs in the world.
We operate in premium, largely logged-in environments that are inherently more defensible and more measurable. As dollars consolidate into CTV, they move into a segment where our market share is meaningfully higher and our infrastructure is embedded. At the same time, automation and AI are increasing efficiency across the ecosystem, expanding working media, and driving more volume through scale platforms like ours. Secular CTV growth, expanding total addressable market, increasing automation, strong share position. Those forces are durable. We believe Magnite is foundational to how the next era of advertising will transact, and we have never been more confident in our strategic position. With that, I'll turn the call over to David for more detail on the financials. David?
David Day (CFO)
Thanks, Michael. As Michael mentioned, we had a strong Q4 and finish to the year with a great performance in CTV, achieving 20% contribution ex-TAC growth, or 32% excluding political, significantly exceeding our expectations. CTV reached 48% of our total contribution ex-TAC for Q4. DV+ came in below expectations, declining 1% and up 4% excluding political. Adjusted EBITDA grew 9% to $84 million, resulting in a 43% margin. We're pleased with the results, particularly the continued acceleration in CTV growth we saw in Q4. For the full year, contribution ex-TAC totaled $670 million, a year-over-year increase of 10% or 14%, excluding the impact of political. For CTV in 2025, we achieved contribution ex-TAC of $304 million, an increase of 17% or 22% excluding political.
For DV+, we reported $365 million for the year, growth of 5% or 8% ex-political. We processed total ad spend approaching $7 billion. Adjusted EBITDA for the full year 2025 was $232 million, an increase of 18% from 2024, resulting in an Adjusted EBITDA margin for the year of 34.7%. Total revenue for Q4 was $205 million, up 6% from Q4 2024. Contribution ex-TAC was $195 million, up 8% within our guidance range and up 16% excluding political. CTV contribution ex-TAC was $94 million, up 20% year-over-year or 32% excluding political, significantly exceeding the top end of our guidance range.
DV+ contribution ex-TAC was $101 million, a decrease of 1% or an increase of 4% excluding political from the fourth quarter last year. This result was below our guidance range. As Michael noted, we saw a growing spend shift from DV+ to CTV. Our contribution ex-TAC mix for Q4 was 48% CTV, 37% mobile, and 15% desktop. From a vertical perspective, retail, health and fitness, and financial were the strongest performing categories, while automotive was again, one of our weakest performing categories. In DV+, we saw additional weakness in technology and food and beverage. Total operating expenses, which includes cost of revenue, were $153 million, a slight decrease from $154 million for the same period last year.
Adjusted EBITDA operating expense for the fourth quarter was $111 million, $1 million better than the low end of our guidance range, and an increase from $104 million in the same period last year. The increase was primarily driven by higher cloud and data center costs and higher personnel-related expenses, supporting the growth of our CTV business and investment in CTV-related features and functionality, and was better than expected due to lower personnel expenses, including slower than anticipated hiring. Our net income was $123 million for the quarter, compared to net income of $36 million for the fourth quarter of 2024. This was driven by a $90 million one-time tax benefit resulting from the release of the valuation allowance on our deferred tax assets.
As background to the release, we met the specific accounting criteria of 12 quarters of cumulative positive pre-tax income and the necessary expectations for future profitability. Adjusted EBITDA grew 9% year-over-year to $84 million, reflecting a margin of 43%. As a reminder, we calculate Adjusted EBITDA margin as a percentage of contribution ex-TAC. GAAP earnings per diluted share were $0.80 for the fourth quarter of 2025, compared to $0.24 for the fourth quarter of 2024. Non-GAAP earnings per share for the fourth quarter of 2025 was $0.34, compared to $0.34 last year. The reconciliations to Non-GAAP income and Non-GAAP earnings per share are included with our Q4 results press release.
Our cash balance at the end of Q4 was $553 million, an increase from $482 million at the end of the third quarter. Operating cash flow, which we define as Adjusted EBITDA less CapEx, was $61 million. Capital expenditures, including both purchases of property and equipment and capitalized internal use software development costs, were $23 million, consistent with the expectations we discussed last quarter. Debt interest expense for the quarter was $4 million. Net leverage for the quarter was zero, down from 0.3x at the end of Q3. As a reminder, the remaining $205 million principal balance of our convertible notes is a current liability on the balance sheet as the notes mature this quarter. We plan to pay off the converts at maturity with cash on hand next month.
As you know, $400 million in converts were part of our original financing for the SpotX acquisition, and when all is said and done, provided capital at an extremely favorable rate. During 2025, we repurchased or withheld over 5.2 million shares for approximately $79 million. We're also announcing a new two-year share repurchase plan today, which authorizes the repurchase of common stock with a value up to $200 million. Following the repayment of our convert, we plan to be more aggressive with share repurchases, given our future expected significant and consistent free cash flow generation. Our capital allocation strategy will target approximately 50% of free cash flow generation to be returned to shareholders via share repurchases over time, provided our share price provides a reasonable return compared to our estimated intrinsic value.
Note also that M&A opportunities may arise in the future that might change our perspective. I will now share our expectations for the first quarter of 2026 and our current thoughts for the full year. For the first quarter, we expect Contribution ex-TAC to be in the range of $157 million-$161 million, which represents growth of 8%-10%. Contribution ex-TAC attributable to CTV to be in a range of $81 million-$83 million, which represents growth of 28%-31%, surpassing 50% of total Contribution ex-TAC for the first time. TV+ Contribution ex-TAC to be in the range of $76 million-$78 million, which represents a decline of 6%-8%.
We anticipate Adjusted EBITDA operating expenses to be approximately $122 million, which implies Adjusted EBITDA margin of over 23%. As a reminder, the first quarter is always seasonally our lowest margin quarter. For the full year 2026, we anticipate total contribution ex-TAC growth to be at least 11%, Adjusted EBITDA percentage growth in the mid-teens, Adjusted EBITDA margin greater than 35%, free cash flow growth greater than 30%, and 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 ad tech trial. Finally, regarding our tax position, we would not expect to have any significant increases in cash taxes for the next few years.
We are proud of our team's execution and our resulting fourth quarter and full year results. We believe we are very well positioned to continue winning and thriving with the changes that are taking place in the programmatic ecosystem. We continue testing and implementing the right AI capabilities to build on Magnite's industry-leading platform and making strategic investments to improve our efficiencies. With that, let's open the line for Q&A.
Operator (participant)
Thank you. We will now begin the question-and-answer session. To ask a question, you may press star, then one on your touch-tone phone. If you are using a speakerphone, please pick up your handset before pressing any keys. If at any time your question has been addressed and you'd like to withdraw your question, please press star then two. At this time, we will pause momentarily to assemble our roster. Our first question comes from Laura Martin of Needham. Please go ahead.
Laura Martin (Senior Analyst)
Hey there, congratulations. Good numbers. I wanted to talk about the breadth of CTV and how much of that is sustainable. Ex-political, CTV up 32% in growth. Can you break down how much of that is SMBs? How much is by vertical? You named a lot of really big studio companies that are growing. I'm really interested in what's growing and whether you see that continuing. That's my first question.
Michael Barrett (President and CEO)
Yeah, hey, Laura, great question. I'll handle it first, and maybe David will dive in with some specifics. We really haven't gotten into breaking it out. Lord knows we have a hard enough time figuring out TV plus and CTV, buckets, let alone getting a little bit more specific on the CTV. I will say, and you did see the announcement from MNTN recently about their direct connection into us, as their first platform to do so. That's a, that's a very encouraging sign of a high-growth area of, you know, performance, oriented SMBs. We are seeing just across the board, you don't grow at 32% and not have everything firing at all cylinders. Big branded advertisers that used to advertise in TV, we have cited a big shift-
from performance advertisers that were digital online video, digital display, shifting into CTV. you know, throughout all of our channel checks, the same note was sung by every major agency brand marketer. The appeal of CTV, the pricing, the performance metrics of it's really just increasing in velocity of appeal. We're just seeing it across the board, Laura.
Laura Martin (Senior Analyst)
Okay, great. My second question is about risk. It feels like, Michael, we're moving more towards an infrastructure. You have a lot of really specific, deep infrastructure, integrations into some of these large CTV performers. Do you get the sense that elongating your client relationship time, increasing your lifetime value, and lowering the risk of investing in Magnite as a stock?
Michael Barrett (President and CEO)
No question. You hit the nail on the head, and I think we try to harp on that in the call and the script. We look so different in CTV than we do, perhaps even in DV+ and display. We are highly differentiated. We have a leading programmatic ad server that's coupled with the leading SSP platform. We're building more and more tools. We have a buying tool, ClearLine, that's integrated across the board. We look quite different, unique, and, you know, with a enjoyable mode that we built in CTV, which is, as you know, the fastest growing segment in the digital advertising sector.
Laura Martin (Senior Analyst)
Thank you very much.
Michael Barrett (President and CEO)
Thanks, Laura.
Operator (participant)
Our next question comes from Dan Kurnos of The Benchmark Company. Please go ahead.
Daniel Kurnos (Equity Research Analyst)
Great, thanks. Michael, let me just stick with the CTV question for a second. Is there any way to kind of parse out the mix shift to CTV versus your organic partner growth, like what you had before? Because there's a clear acceleration, I think, on both fronts, and how much of that's coming from live events?
Michael Barrett (President and CEO)
Yeah. Live is, it's an increasing contributor each quarter. That's definitely a good guy for us. As it relates to parsing it out, you know, David, do you wanna say kind of the dollar shift that we saw from DV+ into CTV and that to give you some idea of the baseline growth level versus the accelerated?
David Day (CFO)
I guess, I mean, if you just look at the expectations versus consensus for, like, Q1, for example, you've got DV+, you know, $8 million-$9 million, you know, lower, and CTV, you know, higher by that, by that same amount. I'm not sure you can differentiate spend shift versus organic, because the spend shift is rolling into, you know, into our organic numbers and is rolling through, you know, all of those same, you know, obviously all of those same partners. It is a very dramatic shift, right?
Michael Barrett (President and CEO)
Right.
David Day (CFO)
Go ahead.
Michael Barrett (President and CEO)
Yeah, no, I was saying if you looked at it, like, let's just say if the expected performance is 20% and it winds up being 32%, it's pretty easy to parse it out as to what the accelerant was from a spend shift from platform to platform.
Daniel Kurnos (Equity Research Analyst)
No, that's helpful color. I mean, I'm just trying to make sure to flag, I guess, the underlying is still growing ex the shift, so just wanna.
Michael Barrett (President and CEO)
Oh, yeah.
Daniel Kurnos (Equity Research Analyst)
Make sure that we-
Michael Barrett (President and CEO)
Very much so. Yeah, very much so.
David Day (CFO)
Yeah, I think the cool-
Michael Barrett (President and CEO)
The thing, Dan, in from a larger perspective from what we talk about is, you know, those very marketers and making up a number, say someone spends $100 with us, they're just spending it differently, allocating it differently, and good news for us, they're allocating it to the faster-growing platform that you certainly look ahead three to five years from a CAGR standpoint, it's gonna be super impressive. You know, number one, the allocation is happening on our platform, so we're catching dollar for dollar, and we're still having that organic growth on the CTV side that's far exceeding the marketplace. Both very positives for us.
David Day (CFO)
Yeah, just to layer on-
Michael Barrett (President and CEO)
And Michael-
David Day (CFO)
Oh, sorry. I was gonna say layer on to Laura's point, you know, is de-risking, you know, so $1 of CTV, you know, revenue and growth is more protectable and sustainable in some ways than DV+, which can be a little bit more volatile. We, you know, we love, you know, where this is heading ultimately.
Daniel Kurnos (Equity Research Analyst)
Not just that, David. I mean, I guess the next question I'd ask is like, I mean, margins are still improving, but there's always been question around take rate and economics, and you're still driving margins higher. Some of that's been your cost to take out, cost to serve initiatives, but, you know, just maybe any comments you guys have on that would be great. Thanks.
David Day (CFO)
Yeah, in fact, we talked about this a little bit last, I think the last quarter or two, because of the opportunity that we have in CTV, we've actually, you know, made some additional internal investments into CTV, so into engineering, into accelerating some of our feature, you know, and functionality in the CTV business. All things being equal, our margin expansion, you know, could even be, you know, could have been even greater in 2026, with the opportunity. We'll still expand margins, but with this opportunity in CTV, it's sort of a-
A little bit of a one-time shot on the headcount, and continuing to make the improvements on our tech stack infrastructure, as you mentioned, getting better leverage out of that to really set us up for more rapidly expanding margin in future years.
Operator (participant)
Our next question comes from Shyam Patil of Susquehanna. Please go ahead.
Shyam Patil (Senior Analyst)
Hey, guys. I had a couple of questions. I guess maybe following along the lines of the previous two as well. What do you guys think is the right way to think about CTV growth and then DV+ growth kind of going forward? I know you gave kind of 1Q outlook and kind of high level for the year for overall, but what's if we kind of look at the two businesses, like, what's the right way to think about the, like, you know, the growth rate kind of going forward on a sustainable basis? I know, Michael, you said CTV is, you know, a double-digit grower, and obviously, we've seen that strong growth rate.
Just a follow-up, just on Open Path, can you just maybe talk about that a little bit? You know, just kind of the impact you had seen. It, it seems like, you know, that situation might be behind us now. Maybe if you could just talk about, you know, that, and if you think that, you know, that's been resolved and kind of behind us, or if there's, potentially any, anything to be aware of on that front. Thank you.
Michael Barrett (President and CEO)
Yeah, sure. Great questions, I'll let David jump in on some of it. Yeah, certainly, if you look at CTV, you know, the market from an estimate standpoint, has always been on, probably lagging the actual growth rates. I think some of the latest numbers out there are in the, you know, mid to low teens, certainly at 32%, that's far exceeding market growth. That's where we expect to be given our market position. You know, I think, you know, a growth rate in the, you know, high teens, 20s is very sustainable given the secular shift that's going on. As it relates to DV+, I think it's fair to remind everyone the diverse portfolio that DV+ is.
Certainly, there's desktop and mobile web, and that is definitely under pressure. You have all sorts of things happening there, and the big budget shifts that we talked about that we caught on the CTV side were essentially coming from that bucket. You also have emerging categories like audio, digital out-of-home, mobile app, which, you know, you look at the numbers AppLovin's putting up. Mobile app for a long time was kind of out of our reach, because the brand advertising that we source really couldn't compete with the app install. Now it's been on a better level playing field than it ever has, so we view that as a big opportunity for us.
We're deploying our SDK, we're partnering with AppLovin, we're partnering with Unity, we're partnering with all the big players, and we think that that's a big growth area for us. Where does that net out? It's hard to say. But I think the encouraging thing is from a growth profile for Magnite, any weakness that we are seeing in DV+ is manifesting itself in the CTV bucket. Again, if the budget's $100, we're catching the $100. It's just being allocated differently by the marketer. It's a little hard to put a growth rate on DV+, but if you parse it all out, there's going to be growers like mobile app, that's going to be in the teens, and there's going to be desktop, mobile web, that's probably flattish to slightly down, if that's helpful.
You had also asked about Open Path. As you noted, Open Path has been around for years. The reason why it became a subject of focus last quarter was the Koa deployment and Open Path being a default. We had painfully walked through the Q&As and the script about our efforts to turn that around with our biggest buyers. By most degrees, we've been successful in that. The longer tail of Open Path users, those smaller advertisers, smaller agencies, we had already said that that was going to be more of a, you know, street fight. You know, Open Path has played out exactly as we thought it would. It's a, you know, a modest impact in terms of the DV+ performance.
There's no impact on the CTV performance, and everything that we said we were gonna do, we did. I think Open Path has been with us for years and will continue to be with us for years. I think if anything, we've proven that it's not an existential threat to the business, that we have embedded ourselves with our largest buyers to the degree that we become invaluable to them to execute their programmatic businesses.
Shyam Patil (Senior Analyst)
Thank you, guys. That's very helpful.
Operator (participant)
Our next question comes from Jason Kreyer of Craig-Hallum. Please go ahead.
Jason Kreyer (Senior Research Analyst)
Thank you, guys. Michael, you talked about running volumes through AdCP. Just curious what you think the evolution is on that front, and what is the client interest in running volumes through AI agents?
Michael Barrett (President and CEO)
Yeah, you know, interest very high. Reality, very little budgets are being allocated to it. I think, to frame it correctly is, think of this as a massive remodeling of your house, we're not knocking it down and building a brand new house. I think that it's all going to sit on top of the existing infrastructure in the industry. Hundreds of millions of dollars have been invested by Magnite alone to make programmatic work, and what AI agents are going to do is make it work better. It's going to alleviate menial tasks from the traders, the planners, the ops people, and it's going to put more working dollars to play, which is awesome, and we feel it's all going to flow through our pipes.
I think we're doing the exact appropriate amount of investment in it, and we're ready to catch the dollars when they come scaled, but that is not going to happen any coming quarter. Interest high, execution, actually putting your money where your mouth is not high, but we believe we're in a great position, technically and from a market position, to take advantage of this, next wave of innovation.
Jason Kreyer (Senior Research Analyst)
Is that more likely to occur on the DV+ side or on the CTV side?
Michael Barrett (President and CEO)
Well, I think across the board, I mean, the world I describe, there's a lot of heavy lifting that goes on in terms of planning campaigns, introducing opportunities for publishers introducing opportunities for buyers, making sure it works. Why 9 is broken here? This deal doesn't work here. Why doesn't it work? 20 hours of troubleshooting to figure out, and then half the budget's already not been spent, and it's and you're wasting time. I think there's all sorts of efficiencies that are in play across both platforms with an agentic approach as the UI level, and then the plumbing and the infrastructure powered the way it needs to be, the way Magnite does it.
Jason Kreyer (Senior Research Analyst)
A quick follow-up for David. The EBITDA OpEx is a pretty big jump from Q4-Q1. Just curious if you can, maybe talk about what investments are embedded in there?
David Day (CFO)
Yeah, if you recall, we kind of have that jump literally every year. You have personnel raises effective January 1st that kick into place. You also have employer taxes that kick into place, and some of those are attached to some annual grant vesting in that Q1. We have, you know, an offsite that occurs in the first quarter of the year. Certain years, it's full company, certain years, it's the commercial team. So you just got a number of those things, and then the other component there would be some of the investment that I mentioned earlier, which is engineering and product talent for, you know, supporting the pace of development and velocity in our CTV business.
Those kind of make up that increase.
Jason Kreyer (Senior Research Analyst)
Great. Thanks, guys.
Operator (participant)
Our next question comes from Shweta Khajuria of Wolfe Research. Please go ahead.
Shweta Khajuria (Managing Director, Senior Research Analyst)
Okay. Thanks for taking my questions. Let me try two, please. I have a follow-up on the prior one. Michael, if you could please explain the Context Protocol, like how it works, what the real value proposition is, and what your differentiated advantage is there. As it relates to Cloud X, is that a competitive product? Is that even related? How should we, how should we think about how all this evolves in an agentic world, and what the impact will eventually be? Is it that you're gonna get greater share of ad dollars? Is it that the dam will expand? Like, how should we think about the impact, and how it works? Then the second question I have is, just on the App Stack case, you touched on it in your prepared remarks.
What is the base case expectation at this point? What should investors be expecting in terms of a realistic outcome? If you have any sense on the timeline, that'd be great, too. Thank you.
Michael Barrett (President and CEO)
Yeah, sure, Shweta. Yeah. You know, AdCP is, you know, it's a protocol that allows agents to talk to agents. There's nothing particularly unique about that. It's making sure your program can be agentic. It's making sure your platform can have agents talk to each other. I think that we, given the size of our platform and the appeal of the types of publishers we have, you know, we were approached by Scope 3 first to execute that.
I think it's a less sensitive to the fact that we're prepared for, you know, to move beyond the API world and get into the MCP, AdCP world, where agents are talking to agents and need a point of connection, as opposed to APIs, where it was more people connecting to machines. I think that, we feel very good about that. Where I think our point of differentiation will lie, not just in our readiness, but I think in this, the vast amount of data that we sit on, in the years and years of the data that we have, when we can help our publishers and help our buyers from an inventory discovery, price discovery, to maximize yield for publishers from mediation, I think that that's where the magic really happens.
Anyone can build an agent. The question is: What data is that agent working on? I think we feel that we sit on this repository of data across tens of thousands of publishers, many, many years of data worth, to be able to inform decisions. We've also organized the taxonomy of all the publishers on our platform, so that if someone's looking for sports enthusiasts or auto enthusiasts, that the same protocol exists across all publishers, so we can scale these, what would be very niche buys across agents. Feeling very good about that. You also asked about MAX. Obviously, that's more germane in the mobile area, but we're integrating into MAX right now, which is a newer mediation platform for mobile app. We're e-excited. We know the guys well.
I think it's just another opportunity to gain access to a super fast-growing area of the DV+ business, which is app, and we, you know, are working closely with them. It's a good thing for us, not kind of a disintermediation by any stretch. Lastly, in the ad tech case, you know, very hard to pick timing. The expectation is it's any week now, but that could be delayed a little bit longer. As it relates to predicted outcome, again, that's a little difficult.
I think given the types of conversations that were had in the final prejudgment hearing between Google and the DOJ, it certainly seemed that given the questions from Judge Brinkema, that structural was probably not going to be the likely outcome, that behavioral remedies were. I think some people misinterpreted that as, "Oh, that's not a good guy for Magnite or their peers," which we couldn't disagree with more violently. We were always expecting behavioral, and we thought that as long as through behavioral or structural, it really didn't matter to us, as long as the playing field was more level, that we would be a huge beneficiary of that, and we still believe that to this day.

Our next question comes from Matthew Swanson of RBC Capital Markets. Please go ahead.
Matthew Swanson (Equity Research Analyst)
Hey, guys, this is Simran for Matthew Swanson. Congrats on the quarter. It seems like you guys have hit this tipping point in CTV, which has been great to see. What would you think from an ecosystem standpoint has changed, and how much would you attribute to the secular market shift versus your growing company-specific moat?
Michael Barrett (President and CEO)
Yeah, thanks for the question. I think David touched upon that when he gave us specifics about, you know. Perhaps it was the $9 million came from the DV+ platform, and that was placed on the expected $9 million that we thought were gonna be spent on DV+ was now spent on CTV. That's on top of an already high-growing base of organic spend there. You know, I think no matter how you look at it, you take the $9 million off, you put it back on DV+, you're still looking at a 20%+ grower, which is significantly above market average. I think that you're right about the tipping point.
It's just, it's being accelerated by a spend shift from one platform to the other, but it's inherently a much higher growing platform to begin with, and as we pointed out a couple of times, with a much, much bigger moat for us. It's an area where we're very differentiated, deep integrations with all the top streamers, ad server capabilities, quite different from the DV+ market.
Matthew Swanson (Equity Research Analyst)
Got it. That makes sense. Then on the progress with these partnerships and integrations, could you double-click on the ramp of some of these and maybe touch on Netflix specifically, or any other partners that have progressed particularly well?
Michael Barrett (President and CEO)
Particularly in the streaming area, we, when we do our script and we talk about, the, you know, largest, the, you know, most impactful clients of that quarter, we talked LG Ads, Netflix, Paramount, Roku, VIZIO, Walmart, Warner Bros. Discovery. really across the board, we're seeing. You know, in terms of the commerce partner, in the DV+ part of the script that we talked about, you know, you see United Airlines, which has taken a while to ramp, but it's now, you know, contributing well. You know, PayPal, Pinterest, Best Buy has taken a while, but, you know, all these have different flavors of ramps to them.
Some if someone is in the ad business to begin with, having them allow programmatic into their world, tends to impact the revenue line quicker than if, say, you're United Airlines, you've never been in the advertising business, and you're starting from scratch. That's a longer gestation period. They each have their different flavors, but, you know, from time to time, we'll cite the ones that are active and contributing, and that was the list there.
Matthew Swanson (Equity Research Analyst)
Great. Thanks, guys.

Our next question comes from Barton Crockett of Rosenblatt. Please go ahead.
Barton Crockett (Managing Director, Senior Research Analyst)
Okay. Thanks for taking the question. I wanted to ask about your kind of view of the future with AI, given that that's what's really driving all the stocks. I know there's been some questions on it, but I want to see if you can give us your view of how this evolves in this way, which is: Do you see AI as a force for compression of take rates throughout the kind of ad tech sector generally? Do you see this evolving to a circumstance where perhaps LLMs are a front end for ad plans, and then SSPs are kind of a processing agent, so maybe DSPs get squeezed? Do you think that DSPs and SSPs remain kind of players and maybe the smaller competitors in both sectors get squeezed, or any other kind of circumstance?
How do you see this evolving in terms of players and take rates?
Michael Barrett (President and CEO)
Yeah, that's a great question. I think that, you know, I think if you look at an agentic world and you see where the value is created, there's still a tremendous amount of value being created by Magnite, not just in the plumbing piece of it, but in, you know, educating these seller agents with the data that we have to make informed decisions on pricing, to mediate the buyer agents that come in. I think what you really generally see, again, is a renovation of this house, not a leveling of it. It's a much more efficient world where folks are being freed up to do much more sophisticated tasks, as opposed to this back and forth of demand, campaign management, fixing broken line items, all that kind of stuff.
I think that what you'll see is far more media going to work. I think you'll see certain people in between the agents become less valuable. I think that if you look at the top DSPs and what they have built and the rails that they run on, and the top SSPs like a Magnite and what we've built, that the value creation is the same, if not greater. I don't necessarily see a take rate impact in the future, an agentic future for a Magnite.
Barton Crockett (Managing Director, Senior Research Analyst)
Okay. All right. Now, the other topic I was curious about on antitrust. You know, there's been essentially an adoption of behavioral remedies in Europe with Google, essentially just kind of moving to adopt some of the key things that could be coming here. Would you agree that that's kind of a fair description? If so, are you seeing any impact in terms of share shift in Europe from what Google's been doing over there?
Michael Barrett (President and CEO)
Yeah, great question. I don't know if that's. It's a astute observation, but I'm not so sure it's the exact remedies behaviorally that is being sought here in the States. Let's just say it's a portion of that package, the lowest hanging fruit of the package, and it's also the one that requires kind of the most lift on the publisher side. What we have seen is the publishers that actually readjust the rankings of the exchanges and readjust the price floors, that there is improvement, but that's a process, right? This came down in Q4, so no one really starts to monkey with things during Q4, just given how important the quarter is. We'll see that play out.
I think it's just kind of scratches the surface of what the DOJ is looking for here and what Judge Brinkema has been alluding to. I think it's not apples to apples to compare Europe to the United States.
Barton Crockett (Managing Director, Senior Research Analyst)
Okay. All right, that's great. Thank you.

In the interest of time, if questioners could please restrict themselves to one question. Our next question comes from Robert Coolbrith of Evercore ISI. Please go ahead.
Robert Coolbrith (Equity Analyst)
Great, thanks. Just to go back to the CTV strength, you know, any key unlocks, whether it's around demand partners, supply partners or maybe, you know, things that maybe had happened earlier in the year where, you know, the momentum just sort of built up in Q4 and, you know, surpassed your expectations. Just wondering if we could maybe take another crack at that. Secondly, on the agentic piece, is there anything you know, that can come into the market incrementally in terms of, you know, volumes that remain, you know, sort of offline, negotiated, inserted via IO, whether that's through, some sort of electronic data interchange or a fax or wherever, you know, things that can come into the market incrementally, net new to programmatic, from this sort of agentic shift in the market? Thanks.
Michael Barrett (President and CEO)
Great. I'll take the last first. Certainly, I think that that is a area of hope, right? There is still a tremendous amount of dollars that are frozen in the linear world that are insanely rate sensitive. It's more of an automation as opposed to agentic. If you can build tools that allow, at a very efficient pricing, allow those dollars to be transacted programmatically, that is something we've been trying to effect its ClearLine for a couple years now. I think if you can make it even easier and add an agentic piece to it, that could make it that much easier to have it talk directly to the ad server, have it inserted into the ad server.
I think that that's something that is of appeal, that it's not just all biddable, it's not just programmatic, that it is taking insertion orders and just taking the people out of it and making it automated. We have high hopes for that occurring, and I think it would be very beneficial to the Magnite platform. I'm sorry, Robert, the first question again was?
Robert Coolbrith (Equity Analyst)
Just wanted to take another crack at the CTV question about.
Michael Barrett (President and CEO)
Yeah.
Robert Coolbrith (Equity Analyst)
- the inflection point. You know, was there any, you know, demand partner unlock, supply partner unlock that, you know, drove the variance versus your expectations for the quarter? Anything that may have happened in prior quarters that, you know, in retrospect, when you look at it, you're like: Okay, that unlocked in Q2, but it, you know, ramped in a big way in Q4 beyond our expectations. Just wanted to get a sense of, you know-
Michael Barrett (President and CEO)
Yeah.
Robert Coolbrith (Equity Analyst)
Unlock anything that was sort of, beyond your-.
Michael Barrett (President and CEO)
I would say broad-based across the board. you know, obviously, certain DSPs have become stronger. You know, you look at the strength of an Amazon in the space, that's been impressive. Certainly, MNTN, and we've talked about them and the partnership that they've delivered, but I think across the board you see strength in DSPs. I think if one of the things that could be the unlock, Robert, is the, you know, upfront negotiations. So they went stronger than anticipated, but the big question mark was: How much was streaming going to be a part of it? Because all these guys, the big ones, still run linear businesses.
I think what we're finding out is streaming played a huge role in the upfronts, and you're starting to see that come to fruition because those dollars don't get spent until the second half of the year into the first quarter of the year. I think that, combined with some of the strengths of particular partners, has really led to outside growth, in addition to the platform switch from, you know, the DV+ spending in the open web, and now spending in CTV. You add those all together, and you get turbocharged growth rates.

Our next question comes from Eric Martinuzzi of Lake Street. Please go ahead.
Eric Martinuzzi (Senior Research Analyst)
Regarding the CTV performance, I think your comment on verticals was that there was retail strength, health and fitness, financial, and then you talked about weakness in auto, tech, and I can't recall the third one. Just wondering if your, the guide has any change in the assumptions for those verticals. Is it status quo maintains, or is there an expectation of recovery in some of the weaker verticals?
Michael Barrett (President and CEO)
You want to handle that, David?
David Day (CFO)
I think, yeah. I think, yeah, I think status quo is sort of what we've been, you know, what we've been seeing. I would say the trends that we saw, you know, latter half of November and December are kind of continuing across the board into this first quarter. No significant changes on those trends.

Our next question comes from Omar Dessouky of Bank of America. Please go ahead.
Omar Dessouky (Research Analyst)
Hey, guys. Netflix, I think, recently said that they expect their ad business to double in size in 2026. I wanted to ask you how you're thinking about your contribution from Netflix, you know, as you progress through 2026, and how that might affect the overall take rate of your business. I have a follow-up.
Michael Barrett (President and CEO)
Uh-
Omar Dessouky (Research Analyst)
CPVs.
Michael Barrett (President and CEO)
Sure. Yeah, I think that, you know, Netflix has been a terrific partner. We anticipated them to exit this year as one of our toppest, if not top, on a run rate basis, partner, and that certainly has come to fruition. We are anticipating a bigger year for them this year, given their aspirations in this space, and I don't. From a concentration standpoint, you know, the take rate varies, obviously, on the services that we provide. In some markets, we do more than others, and so therefore, I think from a blended standpoint, take rate isn't going to impact the overall up or down.
Omar Dessouky (Research Analyst)
Okay. On Netflix in particular, you know, how do we think about, you know, CTV growth, you know, as we kind of progress through, you know, through 2026, right? It looked like you had a nice acceleration for the last couple of quarters. You know, should we kind of think of an acceleration, you know, for the next few quarters as well, as you try to upsell your products, as Netflix gets bigger? You know, is that kind of the outlook for, you know, how you expect the year to pan out?
Michael Barrett (President and CEO)
You want to grab that, David?
David Day (CFO)
Yeah, sorry. Just clarify when you say CPV gross, growth?
Omar Dessouky (Research Analyst)
Yeah. Year-on-year. If you look at the year-on-year growth in CPV-
David Day (CFO)
No, on CP, CPV. I mean, we have CPM take rate. I'm just want to make sure we're talking the same language.
Omar Dessouky (Research Analyst)
No, growth in Contribution ex-TAC.
David Day (CFO)
Okay. All right. Yeah, I think, I think we're still, I think what you're getting at is sort of mix changes overall, and I think the, you know, in our take rates. I think you're still, I think our take rates on a blended, mixed, you know, basis in CTV have shallowed out, so they're becoming fairly stable. There still is a significant influx of what I would call, you know, premium inventory at our lower take rate tiers. I would expect, you know, to... We're having the Contribution ex-TAC growth rates that we are, even at those, you know, those lower levels.
I would expect that bottoming out, you know, sort of, I think that continues. I think, just from a mix perspective, we have opportunity to grow those take rates, you know, in the coming time. I don't see a huge inflection, an increase in that average take rate in CTV in the near term, but we're building the foundation and the opportunity to provide, you know, those additional services on the demand side and so forth, where we do make a slightly higher take rate, you know, as we go forward.

Our next question comes from Zach Cummins of B. Riley Securities. Please go ahead.
Zach Cummins (Senior Research Analyst)
Hi, good afternoon. I'll keep it to one question, just given the extent of the call. David, or maybe Michael could address on this. Just curious of the strength you've been seeing with agencies, particularly in agency marketplaces. Can you talk about the opportunity you have there, specifically with maybe more ClearLine adoption with some of these key agency partners?
Michael Barrett (President and CEO)
Yeah, Zach, we're very enthused by the adoption and the volume. You know, these things take a while to get going. There's a bit of a sell-in process from agency to their clients, and so it's kind of a crawl, walk, run. The ones that have been up the longest are at run right now, and the others are in various stages. I think that, super encouraged by the model, super encouraged by the contribution for the company, and I think the stickiness is what really matters. That when they build their business with Magnite as the backbone of their programmatic marketplaces, we become more than just a vendor, or a partner that can be put in competition every quarter.
We become much more of a partner that's a much more strategic, longer-term partner, which isn't the easiest thing to do, particularly in the DV+ world. They've been essential to our growth and the success of ClearLine.
Operator (participant)
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 (President and CEO)
Thank you, operator. Before we close, I want to thank our investors and our team. To our shareholders, thank you for your continued confidence and long-term partnership. We remain focused on disciplined execution and building durable value. To our employees around the world, thank you. CTV becoming the majority of our business, the acceleration across streaming, and our early leadership in AI-driven transactions are direct results of your innovation and commitment. The shift towards streaming and automation is structural and still in its early innings. As ad dollars move into CTV, they move into an environment where Magnite has scale, deep integrations, and meaningful market share. We believe we are building foundational infrastructure for the next era of advertising, and we are confident of our best days are ahead. Thank you for joining us. We look forward to updating you next quarter.
I'll turn it back over to Nick to cover our upcoming marketing events. I won't. I'll. You know what? I'll hand those to Nick.
David Day (CFO)
