Criteo (CRTO) Q4 2025 earnings review
Transition Year Pain: Client Loss Weighs on Growth and Margins
Criteo's Q4 results and 2026 outlook are dominated by the previously announced scope reduction of a major Retail Media client. While Q4 Contribution ex-TAC (CexT) held relatively flat (-1% reported, -4% FX neutral), Adjusted EBITDA fell 17% as the company lost operating leverage. Retail Media, usually the growth engine, shrank 18% (FX neutral) due to the $25M quarterly impact from the client transition. While management pivots the narrative to 'Agentic Commerce' and highlights stable Performance Media trends, the immediate financial reality is a 'low growth' 2026 with compressed margins (32-34% guided vs 35% prior).
🐂 Bull Case
Excluding the single large client scope reduction ($75M headwind for 2026), underlying Retail Media CexT is projected to grow ~20% in 2026 (accelerating from 16% in 2025). Same-retailer retention remains high at 99%.
Performance Media CexT grew +2% (FX neutral) in Q4, stabilizing after prior declines. The self-service 'Commerce Go' platform is scaling, with campaign volume up and social channels driving 20% higher ROAS.
🐻 Bear Case
Adjusted EBITDA margin compressed significantly in Q4 (36% vs 43% a year ago) due to lower topline leverage and continued investment. FY26 guidance implies margins stepping down to 32-34%, suggesting costs are not flexing down with revenue.
Guidance for Q1 2026 projects a 9-11% decline in Contribution ex-TAC and Adjusted EBITDA of just $50-55M, marking a painful start to the transition year before any promised H2 recovery.
⚖️ Verdict: ⚪
Neutral/Hold. The strategic pivot to 'Agentic Commerce' is promising but unproven, while the financial drag from the retail media client loss is real and present. Criteo is in a 'show me' phase: investors must wait until H2 2026 to see if growth re-accelerates as promised.
Key Themes
Retail Media Scope Change Impact
The loss of managed services for a large client created a $25M headwind in Q4, causing the segment to contract 17% YoY. This drag will intensify in 2026 ($75M projected impact). While management cites ~20% growth in the 'underlying' base, the reported numbers will remain ugly until this headwind is lapped in late 2026.
Pivot to Agentic Commerce
Management is aggressively positioning Criteo as the infrastructure for 'Agentic Commerce' (AI shopping assistants). They launched a recommendation service for LLMs and are testing sponsored ads within retailer chatbots. While currently yielding zero revenue, this is the central thesis for long-term relevance in an AI-first web.
Operating Expense Rigidity
Despite revenue pressures, Non-GAAP Operating Expenses rose 12% YoY in Q4 to $184M. The company plans to continue investing in AI and 'Commerce Go' throughout 2026. This disconnect between falling revenue (in Q1 26) and rising/flat costs is the primary driver of the margin guidance cut.
Shareholder Returns
Criteo deployed $152M for buybacks in 2025 (72% of FCF). The Board increased the authorization back to $200M. With the stock likely under pressure from the weak 2026 guide, aggressive repurchases remain the primary support for EPS.
Department Store & Fashion Weakness
Macro headwinds persist in specific verticals. Performance Media saw a 13% decline in Department Stores and a 12% decline in Fashion in Q4. This softness is factored into the Q1 2026 guidance and remains a risk if consumer discretionary spending weakens further.
Performance Media Turnaround
A bright spot: Performance Media Contribution ex-TAC grew 2% CC in Q4. The 'Commerce Go' self-service tool is gaining traction (1 in 2 small client campaigns in the US), and cross-channel activation (Social/CTV) is increasing ROAS. This segment appears to have stabilized after years of declines.
Other KPIs
Reversing. Down 17% YoY (reported) and down 18% (FX neutral). This is the first major contraction for the segment, driven entirely by the client scope change. This segment was historically growing 20%+.
Stable. Up 16% YoY. FCF conversion remains healthy at 52% of Adjusted EBITDA. Despite the P&L noise, the business remains cash-generative, supporting the buyback thesis.
Strong. Includes $389M in cash/marketable securities and revolving credit. The balance sheet is not a concern, allowing for flexibility during the 2026 transition.
Guidance
Decelerating sharply. Implies a decline of 9% to 11% at constant currency. This represents the 'low point' of the year as the company laps tiered fees and absorbs the full impact of the client scope reduction.
Decelerating. This compares to $71M (implied from prior Q1s) or significantly lower than the $92M reported in Q1 2025. The drop reflects the high-margin nature of the lost Retail Media revenue.
Stable/Low Growth. Reflects the $75M headwind from client scope changes. Excluding this, Criteo claims 'high single digit' growth. H2 is expected to see a return to growth.
Decelerating. Down from 35% in FY25. Management cites investments in Agentic AI, return-to-office costs, and FX headwinds as reasons for the compression.
Key Questions
Agentic Commerce Monetization
Management talks extensively about Agentic AI, but admitted current guidance assumes zero revenue from it. What is the specific timeline and business model (CPM, CPA, SaaS fee) for monetizing these integrations with LLMs?
H2 2026 Re-acceleration Visibility
The guidance relies heavily on a second-half recovery. Beyond lapping the client loss, what concrete pipeline or signed deals provide confidence that Retail Media will return to double-digit growth in H2?
Cost Structure vs. Revenue Reality
With Contribution ex-TAC expected to fall ~10% in Q1, why are operating expenses not being adjusted more aggressively to protect margins, rather than guiding for a margin decline?
Department Store Exposure
Given the 13% decline in Department Stores in Q4, how much of the FY26 guidance risks further deterioration in this vertical, and is it structural or cyclical?
