Hello, everyone, and welcome to Viant Technologies Second Quarter 2025 Earnings Conference Call. My name is Emmanuel, and I will be your operator today. Before I hand the call over to the Viant leadership team, I'd like to go over just a few housekeeping notes for the program. As a reminder, this call is being recorded. Thank you for your attendance today. I will now turn the call over to Nick Zangler, VP of Investor Relations for Viant.

I would now like to turn the call over to Tim Vanderhook, Chief Executive Officer of Viant. Tim?

Thanks, Nick, and thank you all for joining us today. We achieved excellent results in the second quarter, setting new records across all metrics and surpassing the midpoint of our adjusted EBITDA guidance. Revenue increased 18% year-over-year and contribution ex-TAC increased 16% year-over-year, both in line with our quarterly guidance. This strong growth was fueled by demand for our unique CTV offering, increased adoption of Viant's addressability solutions and wider use of the ViantAI product suite. Adjusted EBITDA increased 18% year-over-year to $11.3 million for the quarter. Operationally, we continue to execute against our strategic priorities. We further advanced our CTV Direct Access premium publisher program through new publisher integrations. We expanded the presence of our industry-leading audience and content addressability solutions, Household ID and IRIS_ID. And we successfully launched the third phase of our ViantAI product suite, AI Measurement and Analysis, designed to revolutionize reporting with on-demand insights. Our innovative solutions are resonating across the marketplace, enabling Viant to actively pursue and secure new business from advertisers with more pronounced ad budgets. More than ever before, we are engaging with major U.S. advertisers and proactively expanding our addressable market beyond the mid-market advertiser. In a moment, Chris will discuss our evolving go-to-market strategy influenced by the ongoing rollout of ViantAI and provide an update on our growing business pipeline with major U.S. advertisers. Before that, I will provide a detailed update on our key strategic priorities: CTV, addressability, and ViantAI. CTV was the strongest driver of top-line growth in the quarter. We continue to position Viant as the preeminent DSP for CTV advertising. And once again, our results demonstrate that we are doing just that. In the first half of 2025, approximately 45% of total ad spend on our platform was CTV, and approximately half of that spend ran through our direct access premium publishers. Unique to Viant, the Direct Access premium publisher program connects advertisers directly to premium CTV inventory, significantly reducing supply side fees. This means more ad spend goes directly toward working media, increasing impression win rates without the need to raise bid prices, improving return on ad spend for our customers. Notable Direct Access premium publishers include the likes of Disney, Paramount, Peacock, Roku and many, many others. We recently welcomed LG, a major CTV OEM to our Direct Access premium publisher program. This partnership offers our advertisers an efficient supply path to reach LG's 45 million connected devices across the U.S. The integration also incorporates data matching, which further enhances the efficacy of Viant Household ID for audience targeting and measurement. Furthermore, LG has integrated Viant's leading content identifier, IRIS_ID, allowing advertisers to target and measure based on content relevance. This leads me to our expanding leadership position in addressability. Viant Household ID, our patented audience targeting and measurement solution continues to see strong utilization amongst advertisers. Household ID identifies approximately 95% of U.S. households and boasts availability across about 80% of biddable ad inventory, significantly exceeding alternative identifiers and enabling sophisticated audience targeting and measurement at unmatched scale. In the second quarter, ad spend linked to Household ID increased 15% year-over-year as we continue to activate Household ID matches with our premium Direct Access publishers, making their inventory both biddable and addressable. We anticipate continued growth in utilization of our Household ID as data-driven advertisers increasingly prioritize the CTV channel. Our content targeting and measurement solution, IRIS_ID, continues to ramp across publishers. Building on existing momentum, IRIS_ID is now integrated with Wurl, a leading CTV content distributor. Under the AppLovin umbrella, Wurl powers over 3,000 FAST channels across more than 55 streaming services and significantly expands the reach of IRIS_ID. Notably, this partnership marks the first time Wurl's premium FAST supply is available via programmatic real-time bidding within any DSP, a testament to our ability to bring new innovative solutions to market. Since acquiring IRIS.TV in November 2024, the presence of IRIS_ID across all available CTV bid requests has grown substantially, and we expect it will continue to climb as we onboard new publishers. As a reminder, IRIS_ID allows advertisers to target CTV ad inventory at the video level, enabling advertisers the ability to align their brand, product or service with contextually relevant content. In doing so, advertisers have been shown to experience a 5x lift in brand favorability, a 3x lift in ad recall, and a 2x lift in brand awareness and consideration versus CTV control groups. As IRIS_ID continues to be integrated amongst publishers, advertisers gain the ability to deploy contextual campaigns at greater scale, which we believe will lead to increased utilization. Finally, I'd like to provide an update on our ViantAI product suite. We have now successfully rolled out 3 phases of our AI product suite with the recent launch of AI Measurement and Analysis in late June. Recall, the rollout of ViantAI consists of 4 total phases, including AI Bidding, AI Planning, AI Measurement and Analysis and AI Decisioning. I'll very briefly touch on all 4. Nearly 2 years after launch, AI Bidding automates approximately 85% of the ad spending on Viant's platform. With AI Bidding, advertisers enable Viant's algorithms to find and buy optimal ad placements across the open Internet, aiming for the lowest cost while meeting their desired KPIs, which often include reach, frequency, and targeting specifications. With surging use, contribution ex-TAC generated from AI Bidding has doubled year-over-year. Early in the third quarter, we rolled out our most impactful AI Bidding model yet. While competing DSPs tout 1% tech fees, our latest AI Bidding model delivers up to 46% reductions in media costs. We believe we are just scratching the surface with AI Bidding. And through continuous innovation, we can deliver even greater savings for our clients. Advertisers can only expect to achieve these types of savings from a buy-side-only platform that doesn't own the ad inventory like Google and Amazon. In Q3 2024, we launched AI Planning, which enables advertisers to create enterprise-level campaigns in seconds. As we have continued to build awareness across the marketplace, we have seen major U.S. advertisers express interest. Relative to our existing customer base, these are bigger brands with more pronounced ad budgets. We are engaged with various CPGs, QSRs, retailers and more. They all see how ViantAI can transform their business. And the feedback is consistent. There is simply nothing else in the market like ViantAI. AI Planning streamlines the workload of media planning and execution teams. Users need only provide an advertiser name, budget, timeframe and goal, and within seconds, an enterprise-level media campaign designed to maximize return on ad spend is fully constructed, inclusive of budget allocation across all digital channels and publishers, audience segmentation, frequency capping, dayparting, CPM pricing, and more. With a single click, the media plan is directly exported into the DSP for immediate execution, automating and streamlining tasks traditionally handled by teams of media planners and traders. It's clear to see why agencies and advertisers of all sizes are eager to work with Viant. AI Planning improves workflow, drives operational efficiency, and delivers a higher return on ad spend. We are very encouraged by recent momentum and expect to win material ad spend from major U.S. advertisers moving forward. AI Measurement and Analysis launched in late second quarter and revolutionizes reporting with on-demand insights. Historically, campaign performance data has been spread across multiple dashboards, buried in spreadsheets, and has required the expertise of specialized data scientists to interpret results and identify actionable insights. AI Measurement and Analysis is the easy button, built to surface actionable insights and optimization opportunities in an instant via a simple, user-friendly, chat-based interface. For agencies and advertisers, AI Measurement and Analysis provides on-demand answers to all campaign performance-related questions and offers optimization recommendations. These features represent a significant improvement to the user experience, and we believe they will further drive our customers to consolidate their ad spend on the Viant DSP. And finally, we expect to launch AI Decisioning in the second half of 2025. We are on the cusp of providing advertisers with a fully autonomous ad solution for deployment across the open Internet. AI Decisioning enables advertisers to grant ViantAI the autonomy to plan, build, execute, and optimize ad campaigns in full. ViantAI is dynamic and is designed to proactively react to market conditions, adjusting campaigns as necessary to deliver the best possible outcomes. And in contrast to big tech black box competition, ViantAI is transparent, providing advertisers with unrestricted insight across campaign performance data, including publisher allocation, clearing prices, return on ad spend metrics, and more. To summarize, we delivered a strong quarter and made significant progress expanding our product capabilities across our strategic priorities, CTV, addressability, and ViantAI. Our commitment to innovation is driving unprecedented engagement with major U.S. advertisers, presenting an opportunity for Viant to take share in a new addressable market. With demand ramping across our platform, we believe we remain well positioned to deliver sustainable long-term growth. Before turning it over to Chris, I would like to take a moment to welcome Brett Wilson to Viant's Board of Directors. Brett is an experienced entrepreneur, executive and investor with almost 30 years of experience in technology, advertising, and digital media. He is the former Co-Founder, President and CEO of TubeMogul, an ad tech company he led from inception to IPO to a successful exit. His extensive knowledge in ad tech and AI will be crucial as we continue to innovate and accelerate our growth, and we're thrilled to have him on the board. With that, I will pass it over to Chris.

Thanks, Tim. I'd like to take a moment to discuss our customer go-to-market strategy and how it has been evolving and will continue to evolve over time. We believe ViantAI permits us the opportunity to expand our addressable market beyond the mid-market advertiser, which has traditionally been our core customer. And we now believe we can win amongst the many hundreds of major U.S. advertisers as well as the many millions of data-driven advertisers comprised of small businesses, performance advertisers, and direct-to-consumer e-commerce brands. For major U.S. advertisers, ViantAI delivers unprecedented operating efficiency and therefore, material cost savings, not attainable through the use of a traditional DSP. And for data-driven advertisers looking to take advantage of our industry-leading addressability solutions, ViantAI is expected to be the fully autonomous do-it-for-me solution designed to onboard advertisers seamlessly through simple integrations and an intuitive user interface and a platform capable of delivering outcomes for advertisers of all sizes. We plan to attack this expanded addressable market opportunity in stages. Naturally, we first introduced ViantAI to our existing advertiser and agency clients. And as the stats indicate, our customers have overwhelmingly embraced ViantAI. As Tim mentioned, approximately 85% of ad spend on our platform runs through AI Bidding. Since its launch, AI Planning has shown increasing monthly utilization with clients engaging in approximately 25,000 interactions year-to-date, including the creation of 1,100 media plans, and early feedback from the launch of AI Measurement and Analysis has been outstanding with a growing number of clients utilizing ViantAI to extract automated campaign insights. And finally, AI Decisioning is on schedule for a late 2025 launch. As we continue to expand the ViantAI product suite, our commitment to exceptional customer service remains unchanged. We plan to fully support clients through ongoing engagement, education, and activation as new capabilities come to market. And of course, we will also continue to aggressively pursue prospective mid-market advertisers where we have traditionally focused. But as Tim indicated previously, with the launch of ViantAI, we are attracting the attention of major U.S. advertisers, and we are engaging with them more frequently than we ever have before. And quite frankly, we have the right to win with major U.S. advertisers. We are in market with a product offering no one else has, capable of providing a level of efficiency no one else can offer. We hear it over and over again from both existing and prospective clients where they tell us, 'There is nothing else like this in the market.' ViantAI is bidding and transacting on behalf of full-time traders, building and executing enterprise-level campaigns on behalf of full-time media planners and extracting insights on behalf of full-time data scientists. This degree of autonomy is in high demand. For advertiser and agency adopters, ViantAI provides a significant opportunity to materially improve their operating structure and deliver scaled business outcomes. And transitioning to Viant from an alternative DSP platform has never been easier. We have torn down the wall of complexity that is purposely embedded into traditional DSPs, complexity that has enabled competitors to retain clients simply because switching costs were too great. With ViantAI, there are no switching costs. There is no need to certify a team of traders, no need for training, no need for familiarity. If you can chat, ViantAI can handle the rest. While competing DSPs are introducing new forms of complexity, we are laser-focused on providing advertisers with an unprecedented level of simplicity. It is the pursuit of this vision that has awarded Viant the opportunity to win business from a growing number of major U.S. advertisers. Over the last several months, we have been actively engaging with dozens of major U.S. advertisers well outside the mid-market classification. Specifically, we have established new relationships with a number of large national beverage companies, quick-service restaurant chains, CPGs, major retailers, convenience stores, and more. At the conclusion of a new business pitch meeting just a few weeks ago with one of the largest adult beverage companies in the U.S., their executives having sat through a number of DSP proposals, we're quick to congratulate our team on building a solution that no other competitor had to offer. Recent new business pitches with major U.S. advertisers have thus far created a pipeline of new opportunities that exceeds $250 million of incremental ad spend. These RFPs that we were invited to are being for the DSP of record starting in 2026 and our multiyear engagements. Next, let's consider the opportunity that exists with the millions of data-driven advertisers who could benefit from advertising on CTV and the open Internet, but have not had the tools to do so effectively. The launch of AI Decisioning scheduled for release in late 2025 is designed to unlock the ability for Viant to address the millions of small businesses, performance advertisers, and direct-to-consumer e-commerce companies that are so heavily reliant and overinvested in search and social walled gardens. This pool of spend is ripe for diversion to CTV and the open Internet. These data-driven advertisers are believed to represent over half of the $240 billion allocated to the U.S. search and social ad market. They are drawn to search and social media channels because these platforms deliver outcomes at scale through the use of an intuitive user interface. We are innovating to deliver a superior solution for deployment across the open Internet. Through the use of our addressability solutions, Household ID and IRIS_ID, data-driven advertisers can precisely target niche consumer audiences in contextually relevant environments and accurately measure performance associated with such targeted campaigns. And through the use of Viant AI's chat-based user interface, planning, building and executing a campaign across CTV and the open Internet has never been easier. AI Decisioning, our fully autonomous, fully transparent, outcomes-based solution represents the means by which we intend to target and attract the millions of data-driven advertisers poised to allocate spend across CTV and the open Internet. Our solution is designed to rival Meta's Advantage+ and Google's PMax offering, but for use across the entirety of the open Internet, not just the walled garden. And in contrast to these black box alternatives, ViantAI is intended to offer complete transparency, providing advertisers with unrestricted campaign insights. And because we do not own any media and are not conflicted in representing any certain publishers, we will be able to generate the most amount of outcomes for our clients without any conflicts. To be clear, we expect to begin to more aggressively pursue this incremental pool of ad spend following the launch of AI Decisioning, which remains on schedule for late 2025. With our unique CTV offering, industry-leading addressability solutions, and ViantAI product suite, we have a right to win across advertisers of all sizes, and we are evolving to capture share of this expanded market opportunity. And with that, I'll turn it over to Larry to provide more detail on our financial performance.

Thank you, Chris. Before I begin, I would like to remind everyone that we have posted a presentation on our Investor Relations website that includes supplemental financial information to accompany today's call. In terms of our results for the second quarter, revenue for the quarter was $77.9 million, representing an 18% increase year-over-year and a 10% increase quarter-over-quarter and was within our guidance range. Contribution ex-TAC totaled $48.4 million in Q2, up 16% compared to the prior year period and up 13% sequentially and was also within our guidance range. Both revenue and contribution ex-TAC represent record results for the 2Q period. Our results would have been even stronger if not for a temporary disruption we highlighted during our first quarter earnings call. In response to economic policy actions from the current administration, three advertisers paused their campaigns during the quarter. This macro-driven development created a headwind of nearly 300 basis points to revenue growth and over 400 basis points to contribution ex-TAC growth in the quarter. During the quarter, we also continued to see meaningful expansion in the number of customers generating significant levels of contribution ex-TAC. On a trailing 12-month basis through Q2, we saw a 23% increase in the number of percent of spend customers generating over $1 million in contribution ex-TAC. Additionally, contribution ex-TAC across our top 100 continuing customers grew by 21% year-over-year on a TTM basis. New customer momentum also remains strong as evidenced by a pipeline of new business opportunities that exceeds $250 million in ad spend attributable to recent engagements with major U.S. advertisers. We believe these trends fueled by growth from both existing and new customers reinforce our strong competitive positioning and support our ability to continue outgrowing the broader programmatic market over the long term. We delivered strong performance across most customer verticals in Q2 with ad spend across business services, CPG, and retail leading the way. CTV remained a core growth driver in Q2, once again accounting for nearly 45% of total platform spend. In addition, CTV spend reached an all-time high for a second quarter, reflecting continued momentum as advertisers increasingly prioritize premium addressable video to drive performance. Spend across all emerging digital channels, CTV, streaming audio, and digital out-of-home collectively represented nearly 55% of total platform spend in Q2, up from 50% in 2024 and 43% in 2023, highlighting the accelerating adoption of next-generation media formats and underscoring our position as a leading partner for advertisers moving beyond traditional display. Video, inclusive of CTV, continues to represent 60% of total platform spend in the quarter, reflecting the continued shift toward high-impact measurable formats. Non-GAAP operating expenses totaled $37.1 million in the second quarter, representing a 1% sequential decline and a 16% year-over-year increase. This includes strategic investments related to the acquisitions of IRIS.TV closed in November 2024 and Lockr closed in February 2025, both of which expand our long-term product capabilities and are intended to support long-term growth. Excluding these acquisitions, organic non-GAAP operating expenses increased a modest 10% year-over-year and declined 1% sequentially, reflecting continued operating leverage and disciplined expense management. Importantly, we remain focused on scaling efficiently. Even as we continue to invest in innovation across ViantAI and our broader technology stack, we are delivering measurable gains in productivity, increasing contribution ex-TAC per employee by 10% year-over-year, a clear signal of improved operational efficiency. Adjusted EBITDA for Q2 was $11.3 million, exceeding the midpoint of our guidance by 3% and growing 18% year-over-year. Adjusted EBITDA as a percentage of contribution ex-TAC was 23% for the quarter, expanding 20 basis points compared to the prior year. This margin improvement was achieved while continuing to invest in our ViantAI product suite and while integrating IRIS.TV and Lockr acquisitions, demonstrating our ability to scale efficiently while executing on strategic priorities. Non-GAAP net income, which excludes stock-based comp and other adjustments, totaled $8 million for the quarter, up 11% from $7.2 million in the prior year. Non-GAAP basic earnings per Class A share outstanding totaled $0.10 in the second quarter compared to $0.08 in the prior year. In terms of share count, we ended the quarter with 62.9 million total shares outstanding, consisting of 16.3 million Class A shares and 46.7 million Class B shares. We ended the quarter with a strong balance sheet, including $173 million in cash and cash equivalents, $192 million in positive working capital, no debt, and full access to our $75 million undrawn credit facility. For the quarter, cash flow from operating activities was $20.9 million, representing a 46% year-over-year increase, reflecting healthy core operating performance. We also remain disciplined in our capital allocation. Since launching our share repurchase program in May 2024, we've returned $50.2 million to shareholders, including $10.8 million in Q2 and $28.5 million year-to-date through August 8. In total, we've repurchased 3.8 million shares at an average price of $13.15, signaling our confidence in our long-term value. As of August 8, approximately $49.8 million remains available under our current authorization. We intend to continue executing this program opportunistically with a focus on maximizing value for long-term shareholders, particularly during times when our stock is undervalued. Our strong financial foundation, combined with consistent execution and a balanced capital allocation strategy, positions us well to capture growth opportunities and drive shareholder value in the quarters ahead. Turning now to our outlook for Q3. It's important to note that 2 temporary and nonrecurring factors are expected to impact our near-term revenue and contribution ex-TAC growth, both of which are fully reflected in our guidance. First, we are lapping a high political ad spend comp from last year's presidential election cycle, which represented an approximately 400 basis point headwind for contribution ex-TAC growth in Q3. Second, one of our agency clients lost a sizable advertiser to another agency, prompting the associated ad spend to move off of Viant's platform. While such occurrences are not at all unusual, this advertiser's unique seasonality is important to note. As an outdoor entertainment company, they heavily concentrate their ad spend in the summer months, July through September. Consequently, this loss impacts Q3 contribution ex-TAC growth by approximately 600 basis points and will have a minimal effect on Q4 or subsequent periods. On a combined basis, these near-term headwinds pressure revenue growth by approximately 1,200 basis points and contribution ex-TAC growth by approximately 1,000 basis points in 3Q '25. Given these factors, our guidance for the third quarter of 2025 is as follows: Revenue of $83.5 million to $86.5 million, up 6% year-over-year and 9% sequentially at the midpoint. Contribution ex-TAC of $51 million to $53 million, reflecting 10% year-over-year growth and 8% sequentially at the midpoint. Non-GAAP operating expenses of $37 million to $38 million, up 15% year-over-year and 1% sequentially at the midpoint. Adjusted EBITDA of $14 million to $15 million, representing a 1% year-over-year decline and a 29% increase sequentially at the midpoint. Despite the noted temporary and nonrecurring factors, the midpoint of our guidance performance across revenue and contribution ex-TAC has never been stronger and is supported by over $250 million of potential annualized ad spend opportunities associated with major U.S. advertisers, a new addressable market for Viant. These represent 2026 opportunities. And accordingly, we have the potential to exhibit accelerating revenue and contribution ex-TAC year-over-year growth rates throughout 2026. In closing, we delivered another record quarter, executing against our strategic priorities, advancing innovation across our platform, and returning capital to shareholders through opportunistic share repurchases at compelling valuations. We believe we are well positioned for sustainable long-term growth trends, including CTV, addressability, and ViantAI. And with that, I'll turn the call back over to the operator for questions.

We will begin with Andrew Marok of Raymond James.

Great. So first, I wanted to talk about the ViantAI innovations and kind of this broader trend we've been hearing about performance TV getting a lot of airtime in the space recently. So I guess as you're going to market with your new solutions, how are you really standing out against what's becoming seemingly an increasingly crowded market? And then maybe related to that, what's involved in the sales team switch to going more upmarket? Is it more a reorganization? Or will there be incremental hiring involved?

Sure. Thanks, Andrew, for the questions. I'll take the first one on performance TV. The precursor to actually performing in TV is to have great addressability solutions, the ability to target and then, of course, measure those responses. So we believe we have a huge advantage with the patented Household ID, which enables all that addressability to get the ads in front of the right user and tracking it all the way through to the point-of-sale systems out there. So we've been leading in this area. Many of our customers are using it day to day. But of course, as we talked about in launching fully autonomous will enable us to go down market into those smaller advertisers looking to get on TV and drive performance. Do you want to take that?

Yes, Andrew, regarding the expanded opportunities with large customers, we are being actively engaged. A few quarters ago, when we launched ViantAI, we became the first ad tech platform to release a tangible AI product. This has led us to connect with a broader U.S. advertiser base. Our existing sales team has been instrumental in addressing these opportunities, but we are also hiring an enterprise team to pursue larger clients. Our core team will continue to focus on mid-market advertisers and agencies. There is significant potential in the large customer segment as they recognize the cost efficiencies and improved performance from adopting ViantAI. Many brands are facing challenges such as tariffs and have experienced a similar trend to other clients, where their marketing KPIs improve but total sales or market share decline. This presents a major opportunity for us, as marketers are seeking solutions. CEOs are questioning their CMOs about the effectiveness of their spending since they see better KPIs but lower sales. ViantAI can address this issue. Marketers have been focused on improving their KPIs, which has led them to seek out search and social advertising targeting an audience that already intends to buy. However, they are missing the opportunity to engage the entire sales funnel. ViantAI will help them achieve this in a more efficient way.

Our next question comes from Maria Ripps of Canaccord.

First, I would like to elaborate on the previous question regarding achieving $250 million in ad spend. As we consider ViantAI and the functionalities you now provide, are there any specific features or aspects of your offering that are particularly appealing to larger marketers?

Yes, Maria, thank you for the question. A significant aspect is AI Bidding. Tim mentioned that over 85% of total ad spend on our platform is utilizing AI Bidding. In discussions with various DSPs, the focus often shifts to platform fees or take rates. However, while some competing platforms may offer a 1% savings, we're demonstrating that AI Bidding can achieve up to 46% savings in media costs. This represents a substantial benefit for these brands. When we can present this value that ViantAI brings, it leads to straightforward discussions. It's not merely about take rates or reducing fees; it's about maximizing our contributions to them. Many brands, as I mentioned, are facing challenges with market share performance. For instance, if it’s a consumer packaged goods company, their marketing budget typically aligns with a percentage of their total sales. If those sales are declining, their budgets may also be reduced. Therefore, the question becomes how to gain market share despite shrinking budgets. ViantAI and AI Bidding specifically address this challenge, providing clear value to brands, and that's where we see strong engagement from them.

Got it. That's very helpful. And then, Larry, can you maybe just expand on sort of on this client that was lost by one of your agencies. So I think you mentioned that Q4 impact will be minimal, and you mentioned that's due to seasonality. How should we think about sort of impact in the first half of next year from this client?

The good news and the bad news about this situation is that while it significantly affects Q3, most of their budget was utilized in that quarter. Thus, in Q1, it will be less than 100 basis points, which is relatively minor. We do not anticipate it to have a considerable effect on us moving forward. Ideally, we would like to regain the advertiser, but if we do not succeed, it will not significantly influence upcoming quarters.

Our next question comes from Laura Martin of Needham & Co.

I also have two. I'd like to follow up on Maria's question because I agree that this $250 million number that you gave on this call is the most interesting number. The way you framed it in the prepared remarks is it was incremental ad spend. Well, that would like double my number for you for next year for gross revenue. So I want to really drill down. Is it all incremental this $250 million? Or is some of it already in our estimates for next year?

Thanks for the question, Laura. That $250 million is additional. This is a market segment where we haven't strongly competed before. These are all request for proposal opportunities, and they actively sought us out. We see that our addressable market so far has mostly been in the mid-market. Out of that $250 million, we have already secured some of it, but it won’t begin until 2026. In nearly all of these cases, many of these brands are already committed to larger demand-side platforms, and those commitments will conclude in 2025. Therefore, we anticipate capturing a significant portion of these opportunities. The ones we have already secured, along with others we are close to finalizing, will also commence in 2026.

Really interesting. Okay. My other question is about cadence. I really appreciate how you've communicated the concepts of AI Bidding, AI Planning, AI Measurement, and AI Decisioning. I'd like to know the trajectory for Planning, Measurement, and Decisioning, given that you're already at 85% of your ad spend using AI Bidding. How do you see those developing across the quarters?

The planning process typically occurs at the beginning stages, aiming for adoption rates similar to Bidding from the outset. This means that before each quarter, depending on campaign execution—which could be quarterly or monthly—we hope to achieve a comparable adoption rate for Planning as we do with Bidding in the first two years following the launch. It's essential for media planners to understand the reasoning behind the selection of media partners. As for Measurement and Analysis, this aspect differs significantly. It should be utilized almost daily by media traders seeking new insights and recommendations on how to optimize performance effectively. Therefore, while Planning will focus on the percentage of campaigns initiated through our system, Measurement and Analysis should see increased regular use. The Decision-making phase will grant complete autonomy, allowing users to operate without needing to adjust levers, provided they are familiar with the media plans and optimization strategies. Our objective is to achieve full adoption of Decisioning within two years.

Okay. Super helpful. Doesn't this work a little bit against your revenue growth? Like when you tell me that you're saving clients 46%, and then you tell me that you grew revenue, net revenue, which is what I care about by 16%, why didn't you save them 20% and grow revenue by 25%? I don't understand why you're not working against yourself.

Well, in that scenario, and really with a lot of these products, we offer value-based pricing, and we're trying to pass the vast majority of the savings to the customer. In the end, when they get cheaper CPM prices, they get more impressions, they're reaching more people, more potential customers. And our thesis is that if they keep getting better and better performance, they're going to end up spending more. What they're not doing, if they're saving 46%, they're not taking those savings and then taking the budget off the table. They're reinvesting that into more working media. And again, over time, we feel that if we can get them the best performance, they're going to spend more on our software. So that's really the thesis.

And just the last point, it's also just talking about competition. We do compete with Amazon, Trade Desk, Google. When it comes to Google and Amazon, Amazon isn't going to lower the price proactively of Prime Video CPMs to advertisers. That's really the important part of why we're passing through the savings to the advertiser themselves is they get the benefit of a buy-side-only DSP that works on their behalf only. And we think it's a big long-term strategic advantage against those 2 big walled gardens.

Our next question comes from Matt Condon.

My first one, Chris, you talked about lowering the barriers to getting budgets on to Viant through AI. But can you talk about just more generally, what are the switching costs? So what are the things that ViantAI that locks customers in and create switching costs to retain better over time? What are just the catalyst there with ViantAI? And then my second one is what opportunities are there for you to build more direct relationships with brands so that you don't run into the same problem of a brand just switching agencies in the future? Are there opportunities for that?

Yes. The barriers that traditionally exist for demand-side platforms drop significantly once users become familiar with your software, similar to how users become accustomed to a PC or Mac. We've experienced this lock-in effect ourselves. However, we aim to disrupt this by reducing switching costs. Brands are looking to transition from existing DSPs that charge high fees without delivering effective results. Our goal is to minimize any friction associated with moving from one platform to another. ViantAI addresses this effectively. Whether it involves planning or integrating performance data from prior campaigns, users can seamlessly onboard their previous campaign metrics into ViantAI, where it automatically sets up the campaigns. Recently, a customer mentioned that uploading their latest quarterly campaigns, which used to take several days or even up to a week, now only takes them one to two hours. They expressed how much their team appreciates this improvement, which is exactly what we aimed for. Traditional DSPs require specialized training, similar to using Bloomberg terminals. To enhance accessibility on the open Internet, we recognize that around 10,000 to 20,000 advertisers currently operate in this space, while there are millions within walled gardens. ViantAI is positioned to tap into this market, benefiting our core mid-market customers and enabling us to expand towards large US advertisers while also reaching out to smaller businesses and direct-to-consumer e-commerce companies. It's essential to lower switching costs and enhance ease of use, making our platform highly accessible.

And I'll address your question around the direct relationships with advertisers. So certainly, it's stung this quarter by not having it with that current relationship that we cited. But we are investing in the sales force now on building out this enterprise sales team to help drive the relationships with the advertisers directly. Many times, the agency partners are introducing us to the clients directly, but sometimes they don't. And so we have slotted for increasing the sales team to focus on this area to strengthen our awareness at the client level to make sure this doesn't happen again.

But Matt, I want to highlight that our hiring process has been ongoing throughout 2025, and we've seen great success. We will continue to invest in that area. It's not uncommon for clients to switch agencies, and we want to ensure we are prepared for what occurred this quarter. The strategies we already have in place are performing very well.

Our next question comes from Barton Crockett of Rosenblatt.

I wanted to ask really two things. One is just kind of stepping back, I mean, the story that's emerged from this earnings cycle has obviously been one of some concern certainly for the larger player, the Trade Desk around competition from Amazon and maybe faster growth at walled gardens. And you guys had a good quarter, and you've got some specific reasons for why you see a slowdown in the next quarter. But I was wondering if you could talk about what you see in the environment, what's going on? How real are those concerns in your view about Amazon and walled gardens faster?

Yes. I think it depends by vertical category of advertiser, how important Amazon is from a DSP perspective. So certainly, Amazon sells a lot of consumer goods to consumers and where they have valuable transaction data in those vertical categories, they're going to be a big competitor there around CPG. But that being said, Walmart is also a big competitor and these CPGs distribute through 20-plus different retailers at scale. So certainly, in CPG, Amazon has great data and relevant data for those marketers. But I think if you take across the landscape as a whole, Amazon is really not that important when it comes to financial services, automotive and many, many different areas, when it comes to a data set, that would be exclusive to Amazon. So that being said, you mentioned the larger competitor, Trade Desk. If I had a large international CPG where that a lot is sold through Amazon, I could see some pressure there. I think in general, most of these concerns around Amazon's competitiveness at the larger level are overblown from our perspective, but we'll see as it goes.

Yes. When it comes to walled gardens, if you examine their financial performance, many of them are increasing ad load and prices. One key advantage they have is a large number of advertisers, which is something we are actively investing in to capture the largest market share possible. Specifically, when we look at these sell-side players, it's uncommon for us to market ourselves solely as buy-side and explain why that matters. We are unique in working on behalf of our clients to secure the lowest prices available. I remain completely objective and do not have vested interests in any media owner. Our goal is to help clients achieve the best performance. A great question was raised earlier about the discrepancy between cost savings and the slower growth of our contribution ex-TAC. This illustrates that I advocate for the marketer and strive to deliver optimal performance, passing most of the value to them. However, we cannot underestimate these competitors; they represent a significant threat. Collectively, the three major companies account for over 60% of total U.S. ad spend. Thus, we are making substantial investments to compete directly with them and seize the largest market opportunities available. We believe we possess offerings, particularly with ViantAI, that these players do not have, enabling us to tap into the vast market of millions of SMBs, performance advertisers, and e-commerce companies. We are committed to pursuing this opportunity and competing head-on with them.

And then if I could just clarify just one thing on that $250 million number you put out there. Is that essentially a contribution ex-TAC number? Or is that a gross ad spend of which...

Yes, good question. That's a gross ad spend number.

Yes. Our next question comes from Jason Kreyer.

So if we just step out and look at the total AI suite that you'll have intact maybe early 2026, what does that monetization opportunity look like? And how does that monetization opportunity compare to what it looked like before you had the ViantAI products in market?

Yes, let me start. I mean the way that I look at the full monetization opportunity is the ability to go down market to the millions of advertisers that Meta and Google actually have. We view that as their ultimate differentiation is that they have an advertiser in every single subcategory. And so we wanted to bring in a fully autonomous AI ad product across the open Internet that can scale. And I think that's the big opportunity that we're excited about ViantAI as it gives us a scalable play to go down market in terms of size of advertiser. I think that the monetization of it on the current customer set, you're seeing it with AI Bidding. We think there's even bigger opportunities around monetization with Measurement and Analysis as we fully roll that out. That will drive incremental revenue in the future. But long-term, Decisioning and driving outcomes for advertisers, we think it can drastically shape the revenue growth that we can produce.

And just a quick follow-up. The 3 customers you had talked about last quarter that delayed these campaigns, just any updates on if you had any more of that activity? Or if you still feel good about that spend coming online in the back half?

Yes. In our Q3 guidance, we did not include an increase in ad spending from them. This is already accounted for. We did not notice any other advertisers significantly halting their budgets due to tariffs. Overall, I would describe the market as stable. Naturally, we would prefer to see these deals finalized by the administration sooner rather than later. I think all management teams are seeking certainty, particularly regarding their supply chain. However, I would say it has remained quite stable.

Our next question comes from Chris Kuntarich.

Just you had called out the political comp of 4 points in 3Q. Could you just remind us real quick what that was in 4Q?

It's about the same. Four points, maybe a little bit higher on revenue, but about 4 points of contribution ex-TAC.

Okay. And any sort of visibility at this point into that advertiser that was about 400 basis points of headwind to rev ex-TAC or there's 3 advertisers that were 400 basis points headwind to 2Q rev ex-TAC growth turning back on in 4Q?

No, we have not heard from them. Our guide for Q3, like Chris said, doesn't include them turning on spending, and we will wait and see. Next quarter, we'll give you an update.

Okay. And then just maybe thinking about the $250 million of gross spend and that coming online, could you just remind us from when a client is joining you all? How long does it typically take for them to get up to run rate speed? Should we be thinking about that $250 million as kind of a run rate number as opposed to a full year contribution?

Those are full-year contributions from the 2026 budgets. Depending on the brand, there is different seasonality from Q1 to Q4. However, these are wholesale DSP of record winner take-all budgets.

So in terms of onboarding, it's usually 1 to 2 quarters to onboard a customer. Usually 1 quarter, they're up and ramping in full. But just to clarify, the $250 million that we talked about, it has not all been won. We've won some of those pitches, but the others, they are still in decision mode setting up for 2026.

At this time, there are no more raised hands in the queue.

Great. Thank you, everyone, for joining this quarter's earnings call, and we'll see you next quarter.
