What management had to say 
Criteo CEO Eric Eichmann stated:

2015 was another terrific year for us. We crossed the 10,000 client and 1 billion revenue euro marks while continuing to invest significantly in innovation. I am thrilled to take the helm at such an exciting time and look forward to our 2016 initiatives.

"I am very pleased with our growing profitability and strong free cash flow generation in 2015," elaborated CFO Benoit Fouilland. "Our unique financial model continues to be a key differentiator in our space."

Looking forward 
For the current quarter Criteo expects revenue ex-TAC of 139 million euros to 144 million euros (or $153 million to $158 million), with adjusted EBITDA of 33 million euros to 41 million euros (or $36 million to $41 million). And though we don't lend much credence to Wall Street's quarterly expectations, analysts' consensus called for revenue near the low end of Criteo's guidance range.

Finally, for the full year, Criteo anticipates revenue ex-TAC growth of between 30% and 34% at constant currency. Here again, analysts' consensus predicted revenue ex-TAC growth on a reported basis of 30% -- and keep in mind given the geographic sources of Criteo's revenue, reported growth is generally higher on a percentage basis than constant-currency growth.

In the end, Criteo's healthy new customer additions and high customer retention rates show its advertising solutions are well received, and the company continues to translate that success into one impressive quarterly financial performance after another. Given Criteo's propensity for under-promising and over-delivering, and with shares still down more than 15% year to date as of this writing, it's no surprise Criteo stock is skyrocketing today.
