Gambling.com Group (GAMB) Q4 2025 earnings review
Pivot to Data Services Saves Top Line, But Margins and Core Volumes are Collapsing
Gambling.com Group masked a severely deteriorating core affiliate marketing business with booming sports data sales. Total Q4 revenue grew 31% to a record $46.2 million, almost entirely driven by the OpticOdds/OddsJam segment. However, underlying traffic metrics are flashing red: New Depositing Customers (NDCs) plunged 32% YoY to just 98,000. To offset Google SEO headwinds, management shifted to lower-margin traffic acquisition channels, crushing profitability—Adjusted EBITDA margin compressed to 33% from 42%. The 2026 guidance is the biggest concern, projecting a severe deceleration in revenue growth to ~6% and a reversal in Adjusted EBITDA, which is guided to shrink by roughly 7% year-over-year.
🐂 Bull Case
The sports data business is rapidly scaling, up 440% YoY to $11.8M in Q4 (26% of total revenue). It provides a highly predictable, recurring subscription revenue stream that insulates the company from pure affiliate volatility.
For the first time in company history, revenue not dependent on SEO exceeded SEO revenue, indicating that the multi-channel diversification strategy (apps, paid media, CRM) is taking root.
🐻 Bear Case
NDCs dropped to 98,000 in Q4, down from 145,000 a year ago. The core affiliate business grew just 4% in Q4, and the shift away from organic search is permanently degrading the company's margin profile.
Net income turned deeply negative (-$26.9M) due to a $14M impairment loss and $18.5M in contingent consideration. Operating Cash Flow turned negative (-$9.9M) as legacy M&A earnouts drained liquidity.
⚖️ Verdict: 🔴
Bearish. While the pivot to data services provides an excellent lifeboat, the core marketing engine is struggling. The resulting margin dilution and dismal 2026 guidance signal a structural reset in the company's profitability.
Key Themes
Sports Data Services Becoming the Growth Engine
The OpticOdds and OddsJam acquisition has completely altered GAMB's growth profile. Data segment revenue accelerated massively, growing 440% YoY and 29% sequentially to $11.8M. Management noted that enterprise sports data services will be the primary driver of top-line growth in 2026.
Structurally Lower Profitability
The shift away from high-margin SEO traffic toward paid and diversified channels is exacting a heavy toll on the bottom line. Q4 Cost of Sales spiked 215% YoY to $6.9M. Consequently, Adjusted EBITDA margin contracted from 42% in 24Q4 to 33% in 25Q4. Management explicitly expects margins to compress further to approximately 30% in 2026.
Heavy Non-Cash Charges and Cash Earnouts
GAMB recorded a massive $26.9 million net loss in Q4. This was primarily driven by a $14.0M non-cash impairment loss on intangible assets and an $18.5M fair value charge related to the outperformance of the Odds Holdings earnout. While the earnout reflects strong data performance, it drained $18.6M in hard cash during the quarter, pushing Operating Cash Flow negative.
European Macro & Regulatory Headwinds
International markets are creating significant drag. The U.K. segment faces higher-than-expected increases in gaming duty that will suppress player lifetime values and volume. Additionally, new regulations in Finland will curtail performance marketing, adding further pressure to 2026 growth.
Rapid Channel Diversification
Management's strategy to reduce reliance on Google is working faster than anticipated. For the first time in the company's history, non-SEO revenue channels surpassed SEO revenue. However, this transition is the root cause of the current margin compression narrative.
Other KPIs
Decelerating severely. This is a 32% drop compared to the 145,000 NDCs delivered in 24Q4, and lower than the 101,000 delivered in 25Q3. The ongoing decline highlights the tangible impact of poor organic search rankings.
Reversing. Turned sharply negative compared to +$13.7M a year ago. This was largely driven by a heavy $18.6M deferred consideration payment related to the Odds Holdings earnout termination.
Stable quarter-over-quarter (up 15% from Q3), but Decelerating heavily on a YoY basis, posting just 4% growth compared to the overall company's 31% top-line expansion.
Guidance
Decelerating significantly. The $175M midpoint implies just 5.8% YoY growth, a massive slowdown from the 30% growth achieved in FY25. Management attributes this to continued poor search dynamics and regulatory headwinds in the UK and Europe.
Reversing. The $54M midpoint implies a 6.9% YoY decline compared to FY25's $58.0M. Management explicitly stated full-year margins will compress to roughly 30% (down from 35% in FY25), driven by traffic diversification costs and investments in an unannounced new product.
Key Questions
Intangible Asset Impairment
You recorded a $14.0 million non-cash impairment loss on intangible assets this quarter. Which specific historical acquisitions or assets does this relate to, and is there further write-down risk?
Long-Term Margin Profile
With 2026 Adjusted EBITDA margins guided down to 30%—and expected to be even lower in the first half—what is the new long-term steady-state margin for the business now that non-SEO traffic makes up the majority of revenue?
Core Marketing Health
New Depositing Customers fell 32% year-over-year to 98,000. Is sub-100k NDCs per quarter the new normal, or does the 2026 guidance factor in a recovery in affiliate volume?
New Product Investment
Guidance mentions investments for the development of a new product launching later this year with marginal revenue contributions expected in 2026. Can you provide any color on the TAM or vertical for this product?
