Zeta Global's Q1 2026 revenue jumps 50%, EBITDA up 42%, yet shares trade below 17x forward earnings.

Zeta Global Holdings reported a strong Q1 2026 with revenue rising 50% to $396 million and adjusted EBITDA increasing 42% to $66 million. The company saw a 19% rise in super-scaled customers and a 21% increase in average revenue per user, reaching about $1.7 million. Despite these robust financial results and growth prospects targeting over $2.3 billion in revenue and 25% EBITDA margins by 2028, Zeta's stock trades at a relatively low valuation below 17 times forward earnings. This suggests the market may be undervaluing the company due to lingering concerns about the advertising technology sector and past negative sentiment.
