Looking back on advertising & marketing services stocks’ Q4 earnings, we examine this quarter’s best and worst performers, including Magnite (NASDAQ:MGNI) and its peers.

The sector is on the precipice of both disruption and growth as AI, programmatic advertising, and data-driven marketing reshape how things are done. For example, the advent of the Internet broadly and programmatic advertising specifically means that brand building is not a relationship business anymore but instead one based on data and technology, which could hurt traditional ad agencies. On the other hand, the companies in the sector that beef up their tech chops by automating the buying of ad inventory or facilitating omnichannel marketing, for example, stand to benefit. With or without advances in digitization and AI, the sector is still highly levered to the macro, and economic uncertainty may lead to fluctuating ad spend, particularly in cyclical industries.

The 7 advertising & marketing services stocks we track reported a slower Q4. As a group, revenues beat analysts’ consensus estimates by 1% while next quarter’s revenue guidance was 62.8% above.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 18.9% since the latest earnings results.

“CTV performed well above expectations based on strength from our partnerships with many of the largest industry players. Our DV+ business grew modestly in Q4 due to marketers pausing campaigns after the election, but has rebounded since the start of 2025 and resumed growth in the mid-to-high single digits. We are very encouraged with partner and agency traction to start 2025, and have also made strides to improve efficiency across our business.” said Michael G.
