Shares of Zeta Global Holdings Corp. (ZETA) surged 13.23% in Tuesday's trading session, following the company's release of impressive second-quarter results, raised full-year guidance, and announcement of a new stock buyback program. The AI Marketing Cloud company continues to demonstrate robust growth, marking its 16th consecutive "Beat and Raise" quarter.

Zeta Global reported Q2 revenue of $308 million, surpassing the analyst estimate of $296.7 million. The company's strong performance extended to its bottom line, with a reported free cash flow of $34 million for the quarter. Building on this momentum, Zeta raised its full-year 2025 revenue guidance to a range of $1.258 billion to $1.268 billion, representing a year-over-year growth rate of 25% to 26%. Additionally, the adjusted EBITDA guidance was increased to between $263.6 million and $265.6 million, indicating a 37% to 38% year-over-year growth.

Investors were further encouraged by the announcement of a new $200 million stock repurchase program, authorized through December 31, 2027. This, coupled with bullish options activity detected earlier in the day, contributed to the stock's significant rise. CEO David A. Steinberg attributed the company's growth to recent product releases, platform expansions, and new client wins, expressing confidence in Zeta's ability to capture even more market share in the competitive AI-powered marketing landscape.
