Why Is Zeta Global Stock Down Today?
A beat-and-raise with margin expansion to match — undone by investor concern over customer acquisition costs.
- Zeta Global beat Q2 2026 estimates — revenue of $443 million against a $420.66 million estimate, up 44% year over year — and raised FY2026 revenue guidance by $33 million to $1.811-1.824 billion, yet shares fell 11.911%.
- Adjusted EBITDA reached $92 million at a 20.7% margin, up 170 basis points year over year, and Q3 guidance of $469-472 million came in above the $461 million consensus.
- Unlike Advanced Energy Industries the same week, whose beat-and-raise held, Zeta's raise did not overcome investor concern about rising customer acquisition costs eating into the growth.

Zeta Global beat Q2 2026 revenue estimates — $443 million against a $420.66 million estimate, up 44% year over year — and raised full-year 2026 revenue guidance by $33 million to a new $1.811-1.824 billion range. Shares still fell 11.911% on the day.
The raise was real, and still wasn't enough
This was not a token guidance bump. Adjusted EBITDA reached $92 million at a 20.7% margin, up 170 basis points year over year, and Q3 2026 revenue guidance of $469-472 million came in above the $461 million consensus. On paper, Zeta beat, raised, and guided the next quarter above street expectations — the same pattern that sent Advanced Energy Industries up double digits the same week.
What made the market treat it differently
The difference is what the raise is being read against: investor commentary around the print centered on rising customer acquisition costs, a concern about the durability of Zeta's growth rate rather than its current size. A 44% revenue growth rate draws scrutiny on how much of it is bought growth versus organic demand, and that scrutiny is what a raised guidance range alone did not resolve.
What to watch
Sales and marketing expense as a share of revenue in the next print is the number that answers the customer-acquisition-cost question directly — if it holds flat or improves alongside the 170-basis-point EBITDA margin gain already shown this quarter, the growth looks more durable.
