Zeta Global Holdings Corp. (ZETA) saw its stock price surge 6.08% in the post-market session on Thursday, following the release of its first-quarter financial results.

The significant price movement was driven by the company reporting quarterly revenue of $396.3 million, which substantially exceeded analyst estimates of $370.4 million. This represents a 50% increase compared to the same period last year. Furthermore, Zeta Global raised its revenue guidance for both the second quarter and the full fiscal year 2026, signaling strong continued growth expectations to investors.

Additional factors contributing to positive sentiment include the successful launch and rapid adoption of the company's AI-powered Athena platform, which was cited as a key growth catalyst. The company also noted this marked its 19th consecutive quarter of exceeding expectations and raising its outlook.
