Is ZETA a Buy as Growth Surges While Its Valuation Stays Expensive?

Read MoreHide Full Article

Key Takeaways

  • ZETA raised its 2026 revenue outlook to $1.853-$1.857 billion, implying 42% y/y growth at the midpoint.
  • Athena adoption topped 50% of super-scaled customers, while top users' revenue grew over 70% y/y.
  • ZETA's free cash flow surged 73% y/y to $81.5 million, but its 31.3X forward P/E raises valuation risks.

Zeta Global Holdings (ZETA - Free Report) is pairing faster revenue growth with rising artificial intelligence usage and improving cash generation. Management raised its 2026 revenue outlook after another quarter of accelerating organic growth, giving growth-oriented investors a stronger operating case.

Valuation remains the counterweight. ZETA trades at 31.3X forward 12-month earnings, versus 18.98X for the Zacks sub-industry and 18.8X for the S&P 500. That premium increases the importance of sustained execution.

ZETA’s Revenue Growth Supports the Bull Case

Management now expects 2026 revenues of $1.853-$1.857 billion, with the $1.855 billion midpoint implying 42% growth. Excluding mergers and acquisitions and political candidate revenues, the company expects 27% growth for the year.

Customer metrics reinforce that outlook. Super-scaled customers increased 18% year over year to 212 in the third quarter, while super-scaled customer average revenue per user rose 22% to $2 million. Both measures accelerated from the preceding quarter, showing that growth is coming from customer additions and deeper platform usage.

Zeta’s AI Strategy Is Showing Commercial Traction

Athena adoption is becoming more visible in customer economics. More than 50% of super-scaled customers were monthly active Athena users, while Athena adopters represented more than 70% of revenues. The top 25 Athena users generated revenue growth above 70% year over year in the third quarter, well ahead of Zeta’s overall 46% growth.

AthenaOS and Zeta Business Intelligence are designed to extend the platform beyond marketing into broader enterprise decisioning. Salesforce, Inc. (CRM - Free Report) is also embedding AI agents into marketing workflows through Agentforce Marketing. Adobe Inc. (ADBE - Free Report) has expanded its customer-experience platform with agentic AI capabilities, underscoring the competitive push to combine enterprise data, automation and decision support.

ZETA’s Cash Flow Strength Expands Flexibility

Third-quarter operating cash flow increased 57.7% year over year to $91.3 million, while free cash flow advanced 73% to $81.5 million. Free cash flow margin reached 16.5%, reflecting stronger conversion of growth into cash.

Management raised full-year free cash flow guidance to $270.6-$271.6 million, implying growth of 64-65%. Higher cash generation gives Zeta more room to fund product development and acquisitions while supporting share repurchases. The company had repurchased $101.4 million of shares through Nov. 9.

Zeta Still Faces Mix and Sales-Cycle Risks

Revenue mix remains a profitability consideration. Direct platform revenue represented 71% of third-quarter revenues, down from 75% a year earlier, as agency-led social activity continued to carry lower gross margins than Zeta-owned channels.

Pipeline conversion can also be uneven. Typical product sales cycles run about 90-180 days, while Zeta Business Intelligence opportunities may take longer. A larger enterprise pipeline can support future growth, but procurement and implementation timing can delay when those opportunities become revenues.

ZETA’s Growth Score Outshines Its Value Profile

ZETA’s growth case is backed by accelerating customer metrics, expanding AI usage and rising cash generation, but the valuation leaves less room for a slowdown. The Zacks Consensus Estimate for 2026 earnings has risen 34.9% over the past four weeks, supporting the near-term earnings-revision picture.

The stock currently flaunts a Zacks Rank #1 (Strong Buy). You can see the complete list of today’s Zacks #1 Rank stocks here.

ZETA’s Growth Score of A and Momentum Score of B are favorable for investors focused on growth and price trends, while the Value Score of F points to a weaker valuation profile. The VGM Score of C reflects that trade-off. ZETA therefore offers a constructive setup for growth-focused investors willing to accept premium valuation risk, while more valuation-sensitive buyers may prefer a better entry point.
