Criteo's Guide Miss: The AI-Fueled Future Collides with Enterprise Client Reality

A tale of two Criteos — prudent 2026 guidance on enterprise client weakness vs. an OpenAI flywheel that only starts to matter in 2027

A Guide Miss and a Leadership Change

The headline from Criteo's second quarter is unambiguously negative: revenue of $428M, contribution ex-TAC of $255M, and a revised outlook that now calls for lower budgets from "several large enterprise clients" to persist through the balance of 2026. Management was blunt about the miss, with CEO Michael Komasinski opening the call by saying the quarter was "challenging" and that the company "did not meet the expectations we set for ourselves".

Several large enterprise clients further reduced spending, primarily driven by client-specific decisions and softer demand in specific verticals.

The pullback is concentrated in the international markets — EMEA and Asia Pacific, which together represent roughly two-thirds of Commerce Growth media spend — and spans travel (hit by Middle East conflict), discretionary retail (Fashion down 21%), and client-specific tactic shifts where Criteo "was unsuccessful in retaining that budget". Notably, the tone is far more conservative outlook than in prior quarters. CFO Sarah Glickman framed the guidance as "extrapolating current performance media spending trends through the balance of the year with no recovery assumed from the large enterprise clients that affected our second quarter results." That translates to contribution ex-TAC down 10% to 12% on a constant-currency basis for 2026, with adjusted EBITDA margin guided to roughly 30%. Compounding the top-line tension is a leadership change: Sarah Glickman is stepping down after six years as CFO (remaining as adviser into September), replaced by Connor McGogney, formerly Chief Strategy Officer. The operational math underscores why this matters — revenue is falling slightly, but operating leverage is still positive, with operating margin at 2.9% and free cash flow margin near zero.

The OpenAI Flywheel

The counterweight to the enterprise slump is the OpenAI partnership, which is now squarely Criteo's most exciting — and most un-budgeted — growth driver. Michael Komasinski reports the number of brands running campaigns through OpenAI has "surpassed 2,000, more than double the 1,000 brands we announced at the end of April," with demand integration live in seven countries and more launches planned (Mexico, Brazil, Japan, Korea). The conversion economics are striking:

Traffic from ChatGPT converts at approximately 1.5 to 2x the rate of traditional referral traffic, while roughly 80% of paid traffic is new to the brand.

But here's the rub for investors: 2026 guidance explicitly does not assume "meaningful contributions from OpenAI or our broader agentic AI initiatives." Management frames these as a 2027 growth driver — a strange tension where the company's best-in-portfolio story won't show up in this year's numbers. The stock market has noticed: the name is down roughly 25% from its July high, trading at ~0.5x price-to-revenue, even though the balance sheet holds ~$313M in effective net cash. The key question is whether the OpenAI budgets are incremental or cannibalistic. In the prior quarter's call (May 2026), Michael said OpenAI money is "definitely incremental for Criteo even as we move past test budgets." This quarter, pressed on where the money actually comes from, he was more measured: “today, that is largely test budgets” — Michael Komasinski, Chief Executive Officer · 2026-08-05 — with the bulk of clients reserving a portion of their media plan for testing new formats. The real scaling moment, he suggests, comes when budgets shift from branded search and product listing ads, plus any incrementality from ad spend outgrowing GDP. That's the honest uncertainty, and it explains why the guidance is so deliberately conservative: management doesn't want to bank a trend it can't yet prove out.

Retail Media Resilience, and a Real Strategic Shift

It's not all bad — Retail Media continues to compound underneath the noise. Excluding the two previously communicated retailer scope reductions (a $75M annualized hit), underlying contribution ex-TAC grew 20% in the quarter, with media spend up 31% year-over-year across 4,500+ brands. Sarah Glickman reiterated that the "Retail Media outlook is unchanged," with underlying growth in the high-teens to 20% for 2026. The more interesting strategic story is how aggressively Criteo is building the AI powered shopping layer — the “conversational ad format transforms advertising across the open web into guided shopping experiences” — Michael Komasinski, Chief Executive Officer · 2026-08-05 — with Albertsons as the first retailer to launch shopping-assistant monetization. This is a genuinely company-unique bet: Criteo is trying to become the demand-and-data layer for AI agents, and its MCP capabilities are now integrated into major agency holding companies. But the near-term reality is harsh. In May, you had management explaining away U.S. client softness as a tactical execution issue that would "resolve itself in another quarter or two" — the prior-period quote is telling: “we've not lost any clients there... there really isn't like a common theme running through those other than we've got to be closer to those clients” — Michael Komasinski, Chief Executive Officer · 2026-05-06. Three months later, the trend accelerated and the guide was cut by double digits. The contrarian case is that the OpenAI channel, conversational ad formats, and Retail Media's continued compounding give Criteo a multi-quarter path back to growth as it heads into 2027 — but for now, the market is paying for patience, not a turnaround.
