PubMatic, Inc. (PUBM)·Q4 2024 Earnings Summary
Executive Summary
- Q4 revenue was $85.5M (+1% YoY) but came in below the company’s Q4 guidance range of $86–$90M; non-GAAP diluted EPS was $0.41 (vs $0.45 YoY) while adjusted EBITDA was $37.6M (44% margin), ahead of internal expectations .
- Mix shift accelerated: CTV more than doubled YoY to 20% of revenue; omnichannel video reached a record 43% of revenue, underpinned by political spend and curated live sports inventory .
- Management guided Q1 2025 revenue to $61–$63M and adjusted EBITDA to $5–$7M, reflecting continued headwinds from one large DSP’s auction change; they expect total revenue to resume YoY growth in 2H25 after lapping the DSP impact at end of Q2 .
- Underlying business (ex-DSP and political) grew 16% YoY in Q4; CFO emphasized durable margin structure and cost leverage from owned infrastructure and GenAI productivity gains (+15% in 2024) as catalysts .
What Went Well and What Went Wrong
What Went Well
- CTV scaled to 20% of Q4 revenue, with omnichannel video at 43% of total; “Our platform is rapidly gaining CTV market share as CTV increasingly shifts from insertion order-based buying to programmatic… now work with 80% of the top 30 streamers” .
- Adjusted EBITDA beat internal expectations in Q4 ($37.6M, 44% margin); CFO: “our Q4 adjusted EBITDA came in ahead of expectations… underscoring the benefit… higher-value revenue streams, operational efficiency and cost leverage” .
- Activate and sell-side curation scaling: Activate customers grew nearly 6x YoY; SPO reached 53% of platform activity in 2024, improving efficiency and funneling unique demand to PubMatic inventory .
What Went Wrong
- Revenue missed company guidance as holiday spending from a large DSP underperformed; “strong growth… helped offset softer spending from the large DSP… based on long-term historical trends… single digits” for that DSP .
- GAAP diluted EPS in Q4 declined YoY to $0.26 (vs $0.34 in Q4’23); non-GAAP diluted EPS fell to $0.41 (vs $0.45), reflecting the DSP impact on display .
- Operating cash flow and non-GAAP profitability trended lower YoY in Q4: operating cash flow $18.0M (vs $28.7M), non-GAAP net income $21.4M (vs $24.4M), as mix shift and DSP/display softness weighed on reported totals .

Management Commentary
- CEO (Rajeev Goel): “Revenue growth for the year more than doubled, growing 9% over 2023… CTV more than doubled to 20% of total revenue… we expect accelerated growth in our underlying business as ad buyers seek premium, brand safe, curated inventory” .
- CFO (Steve Pantelick): “In Q4, strong growth in the underlying business helped offset softer spending from the large DSP… our Q4 adjusted EBITDA came in ahead of expectations at $37.6 million or 44% margin” .
- CEO (on CTV marketplace and partnerships): “We continue to onboard new streamers and now work with 80% of the top 30 globally… our CTV marketplace integrates TCL viewership data and premium inventory with our privacy-safe targeting solution” .
- CFO (on structural margin advantage): “A decade ago, we decided to own and operate our own equipment… cost of revenue line didn’t really increase… while impressions increased 20%” .
Q&A Highlights
- DSP headwind specifics: Impact limited to display after a move to first-price-only auctions; holiday seasonality for that DSP was “about half” typical rates; relationship intact; expect apples-for-apples comparisons starting 2H25 .
- CPM and volume trends: Company-wide CPMs positive in 2024; monetized impressions for CTV doubled; underlying business healthy despite DSP softness .
- Data/curation opportunity: Shift to sell-side targeting as cookies wane; >90% impressions carry alternative IDs; Connect integrated with 190 data partners; incremental data fees plus SSP fees drive monetization .
- Political & CTV mix: Political ~6% of FY24 revenue; ~one-third of CTV revenue in Q4 was political; even excluding political, CTV doubled YoY .
- GenAI lever: Expect 5–15% annual productivity gains; GenAI used for internal efficiency and revenue-generating products (e.g., political creative classification) .
Estimates Context
- Street consensus (S&P Global) for Q4 2024 was not retrievable at time of analysis due to SPGI API limit; therefore, comparisons to Wall Street revenue/EPS estimates are unavailable today. Company guidance for Q4 called for $86–$90M revenue and $34–$37M adjusted EBITDA; actuals were $85.5M revenue and $37.6M adjusted EBITDA, implying a revenue miss vs guidance and a modest adjusted EBITDA beat vs the range .
Key Takeaways for Investors
- Mix shift is real: CTV scaled to 20% with omnichannel video at 43% of Q4 revenue; this should support structural margin resilience and higher average CPMs, even as desktop display faces DSP-specific pressure .
- Near-term headwind, medium-term setup: Expect muted 1H25 reported growth due to DSP lapping; management targets underlying business growth of 15%+ and 2H25 total revenue growth in high single digits, setting up for estimate revisions later in the year .
- Execution on buy-side solutions: Activate and SPO are scaling (6x customer growth; 53% of platform activity), increasingly directing unique budgets to PubMatic-integrated supply—supports share gains among premium publishers .
- GenAI is becoming an edge: Demonstrated monetization unlocks (political), publisher tools (Assistant), and internal productivity (+15% in 2024) should provide operating leverage and incremental revenue opportunities .
- Capital allocation remains supportive: No debt; $140.6M cash/marketable securities; ongoing buybacks ($134.6M cumulative through FY24) reduce diluted share count, bolstering per-share metrics over time .
- Watch catalysts: Further CTV/live sports partnerships (e.g., TCL) and curated marketplaces, commerce media integrations (Western Union) that can add unique demand and data-driven performance across the open internet .
- Trading lens: Q1 guide embeds DSP drag; any signs of faster normalization, continued CTV momentum, and adjusted EBITDA margins tracking high-20% for FY25 could be positive stock catalysts; conversely, extended DSP weakness or softer video CPMs are risks .
