PubMatic: 3 Key Takeaways for Long-Term Investors

November 12, 2026 · by TPW Pipeline

On its third-quarter 2026 earnings call, held on Nov. 9, 2026, PubMatic (PUBM +7.99%) announced that revenue grew 17% year over year. The digital advertising provider is capturing market share as media buying moves directly to the supply side, where publisher data remains most intact. Three things management said on the call stand out.

1. Direct Media Buying Accelerates on the Supply Side

Ad buyers are shifting campaign execution directly onto PubMatic’s supply-side platform (SSP), the software that connects digital publishers to ad buyers. This direct access, through the company’s Activate solution, bypasses traditional demand-side platform (DSP) filtering and improves campaign efficiency.

Activate, which directly connects ad buyers to our data-rich inventory, hit an exciting inflection point driven by advertiser performance and efficiency. Buying activity on Activate grew more than 8x over last year and marked a sharp acceleration from Q2.
— Rajeev Goel, Co-Founder and CEO

2. High-Value Channels Drive Expansion in Logged-In Mobile Environments

Premium inventory formats like connected TV (CTV) — ad-supported streaming television — and mobile applications now generate nearly two-thirds of total revenue. Advertisers are allocating spend to logged-in app environments where audience identity signals are reliable.

On a global basis, CTV growth accelerated to over 30% year over year and represented 21% of total revenue. In the Americas, CTV growth was particularly strong at over 40%. Mobile app grew nearly 40% year-over-year and was approximately 27% of total revenue.
— Steve Pantelick, CFO

3. Owned Infrastructure Boosts Processing Efficiency and Profit Margins

PubMatic owns and operates its infrastructure, giving management direct control over hardware processing expenses. By routing compute power toward higher-value impressions, gross margin expanded to nearly 70%.

Monetized impressions grew 15%, while we reduced gross impressions processed by 8%. Because we own and operate our infrastructure, we have control to make these shifts quickly, unlocking incremental revenue while also generating cost savings.
— Steve Pantelick, CFO

Looking Ahead

Ad execution shifts toward automated intelligence, and management is expanding its sales team to capture direct buyer spend. Owned server infrastructure and direct publisher relationships provide structural leverage.

Ad buying across the open internet is quickly being reshaped and the market we serve continues to expand.
— Rajeev Goel, Co-Founder and CEO

A debt-free balance sheet enables continuous investment in graphics processing unit hardware, used for its artificial intelligence solutions, alongside share buybacks.

With a debt-free balance sheet, $144 million in cash and an expanded repurchase authorization, we have both the momentum and the capacity to compound value for shareholders into 2027 and beyond.
— Steve Pantelick, CFO
