Key Financial Performance
Revenue from underlying business Grew 19% year-over-year, excluding the affected DSP and political advertising. Reported revenue returned to year-over-year growth at 6%. This growth was driven by CTV and emerging revenue streams, including Activate, sell-side data targeting, and commerce media.
Adjusted EBITDA margin Achieved 20%, marking the 37th consecutive quarter of adjusted EBITDA profitability. This reflects the robust business model and efficient cost management.
Omnichannel video revenues Grew 34% year-over-year, representing 41% of total revenues in the quarter. This growth was driven by increased adoption of video advertising formats.
CTV revenues Increased by over 50% year-over-year for the fourth consecutive quarter, representing approximately 20% of total revenue in the quarter. Growth was driven by international expansion, new innovative formats, and curated marketplaces like live sports.
Emerging revenue streams More than doubled year-over-year, accounting for 8% of total revenue in the second quarter. This includes platform fees from data curation, commerce media, and enterprise software solutions.
Connect (curation and data business) Grew over 100% year-over-year as publishers and buyers prioritized sell-side targeting through a more controlled and transparent environment.
Revenue from display Flat year-over-year, showing improvement from Q1's year-over-year decline of 10%. This was due to lapping a sizable DSP headwind in the second quarter.
Processed impressions Approximately 78 trillion impressions in Q2, which was 28% higher than last year and a 4% increase versus Q1. Nearly 60% of these impressions were CTV and mobile app, unaffected by AI search.
Top 10 ad verticals Grew in the mid-single-digit percentages year-over-year. Health and fitness, technology and computing, travel, and arts and entertainment each increased over 20%, while shopping, automotive, and business declined by single-digit percentages.
Regional revenue performance EMEA and APAC revenues grew 18% and 7%, respectively, while Americas declined 1%.
Adjusted EBITDA $14.2 million or 20% margin, exceeding the upper end of expectations by over 15%, inclusive of a significant FX headwind.
Total operating expenses $50 million, flat with Q1, as cost savings from AI-driven efficiencies funded investments in high-growth areas like CTV, emerging revenues, and SPO.
GAAP net loss Minus $5.2 million or minus $0.11 per diluted share.
Net operating cash flows $14.9 million in Q2, with free cash flow of $9.3 million. This reflects strong cash generation and financial stability.

Risk or Challenges
Platform changes by top DSP partners: Platform changes by top DSP partners, such as those in July, create revenue headwinds for PubMatic, impacting revenue in the second half of the year. These changes are often implemented with limited visibility, making it challenging to mitigate their effects quickly.
Dependence on top DSP partners: The majority of ad spend on PubMatic's platform comes from top legacy DSP partners. This dependence poses a risk as changes or disruptions from these partners can significantly impact revenue.
Macroeconomic uncertainty: The macroeconomic environment remains uncertain, with sequential weakness observed in consumer discretionary ad verticals in July, potentially affecting revenue growth.
Foreign exchange headwinds: The weakening U.S. dollar has created foreign exchange headwinds, impacting adjusted EBITDA by approximately $2 million in Q2 and expected to continue in Q3.
Competition and industry evolution: The programmatic advertising industry is at an inflection point with blurring lines between SSPs and DSPs and the rapid adoption of AI. This evolution increases competitive pressures and requires significant investment to stay ahead.
Revenue concentration in specific verticals: Certain ad verticals, such as shopping, automotive, and business, showed single-digit declines, indicating potential vulnerabilities in revenue concentration.
Political advertising decline: Q3 revenue is expected to be impacted by the absence of approximately $5 million in political advertising revenue compared to the previous year.

Guidance & Outlook
Revenue Projections: Q3 revenue is expected to be in the range of $61 million to $66 million. This includes a conservative approach due to a headwind from a large DSP and macroeconomic uncertainties. Political advertising, which contributed $5 million in Q3 last year, is not expected to recur.
Adjusted EBITDA: Q3 adjusted EBITDA is projected to be between $7 million and $10 million, factoring in a $1 million-plus impact from the weakening U.S. dollar.
Capital Expenditures: Full-year CapEx is projected to remain at $15 million, reflecting year-over-year reductions due to optimization and cost-saving measures.
Growth in Key Areas: Continued growth is expected in CTV, sell-side data targeting, and emerging revenue streams such as commerce media and Connect. CTV revenue grew over 50% year-over-year in Q2 and is expected to remain a significant growth driver.
DSP Diversification: Efforts to diversify DSP mix are ongoing, with spending from DSPs outside the top 5 growing over 30% year-over-year in July. This is expected to mitigate risks from platform changes by top DSP partners.
AI Integration: AI is being integrated across the tech stack to drive cost efficiencies, enhance campaign performance, and streamline operations. New AI-driven solutions are expected to accelerate adoption and usage of the platform.
Market Share Opportunity: The company anticipates capturing a portion of Google's 60% market share in 2026 due to structural changes in the programmatic ecosystem. A 1% market share shift to PubMatic could represent $50 million to $75 million in net revenue.

Key Q&A
Q:What caused the headwind from a top DSP buyer in July?
A:The DSP buyer shifted a significant number of clients to a new platform that evaluates inventory differently. This change required reimplementation of SPO settings and optimization of inventory sent to the DSP, leading to a notable drop in spend in July, which stabilized in August.
Q:What is PubMatic's strategy to address the concentration of legacy DSP relationships?
A:PubMatic plans to accelerate the diversification of ad spend on its platform away from legacy DSPs. In Q2, spending from DSPs outside the top 5 grew 20% year-over-year, and in July, this growth accelerated to over 30% year-over-year.
Q:How is SPO impacting PubMatic's go-to-market approach?
A:SPO has reached 55% of activity on the platform. Conversations with advertisers are focusing on solving challenges like transitioning away from cookies, performance-based solutions, ROI demonstration, and sell-site targeting. PubMatic is investing in technology solutions like Activate, Commerce Media, and Connect to address these needs.
Q:What is PubMatic's view on the evolution of the ad tech industry?
A:PubMatic sees a shift towards end-to-end platforms driven by trends like CTV, performance-based advertising, identity-based targeting, and AI. The company is focusing on transparency, control, and performance to drive better outcomes for advertisers and publishers.
Q:What caused the inventory changes that led to a headwind in the quarter?
A:The changes were due to a DSP shifting clients to a new platform, which altered how inventory is valued. PubMatic remains a platform of choice due to its scale, omnichannel capabilities, data sets, and global footprint.
Q:What is the concentration of DSPs in PubMatic's revenue?
A:The top 2 DSPs represent about half of PubMatic's overall spending. However, the concentration is declining as other DSPs and advertisers increase their spending. For example, a new #5 DSP emerged in July, and Amazon's revenues grew double digits in June and July.
Q:What is the differentiation of PubMatic's Activate platform?
A:Activate simplifies transactions by unifying DSP and SSP processes, reducing latency, discrepancies, and improving outcomes. It offers transparency and control, allowing buyers to know exactly what inventory they are purchasing and measure outcomes effectively.
Q:What is PubMatic's exposure to generative AI and its potential risks?
A:PubMatic estimates limited exposure to generative AI, with a single-digit percentage of revenue at risk if search traffic to publishers were to cease entirely. The company also sees opportunities in ad-supported AI search and chat monetization.
Q:What is the overall demand environment observed by PubMatic?
A:In Q2, categories like technology, arts, and health grew over 20%, while automotive and business declined. In July, top 10 ad spending grew year-over-year, but there was a sequential decline in consumer discretionary categories. PubMatic is focusing on performance, control, and transparency to navigate uncertainties.
Q:What triggered the DSP platform shift in July?
A:The shift was due to a DSP transitioning clients to a new platform, which changed how inventory is valued. This caused a notable decline in spend in July, but PubMatic is working to optimize traffic shaping and stabilize the impact.
Q:What is PubMatic's approach to mitigating the DSP-related challenges?
A:PubMatic is engaging with SPO partners to reupload their parameters and iterating on traffic shaping to align with the DSP's new requirements. The company is also diversifying its DSP mix and focusing on growth areas like CTV and Commerce Media.
Q:What is the status of PubMatic's buyer sales force build-out?
A:PubMatic is selectively adding resources in mid-tier areas, performance marketers, and emerging revenue streams like Commerce and Connect. The company is optimizing its existing base rather than adding incremental costs.
Q:What is PubMatic's financial position to handle challenges?
A:PubMatic has approximately $120 million in cash, no debt, and generates free cash flow, positioning it well to navigate challenges and invest in growth areas.
Q:Review of Unclear Management Responses
A:Management appeared to avoid directly addressing why the DSP did not provide prior visibility into the changes that caused the July headwind. Additionally, there was limited clarity on the exact timeline for optimizing traffic shaping and fully recovering from the DSP-related challenges.
