Chief Financial Officer Pierre-Jean Sivignon said on Thursday that Carrefour saw the market's consensus for core operating profit of around 2.38 billion euros this year as "reasonable at this stage".
Carrefour is battling to reverse years of under performance in Europe, where it earns 73 percent of its sales. Its problems are partly due to a reliance on the hypermarket format it once pioneered now that customers' habits have changed to favour more local and online shopping.
The world's largest retailer after Wal-Mart said first-quarter sales were 19.79 billion euros, close to the analyst consensus of 19.83 billion, according to Thomson Reuters I/B/E/S data.

First-quarter sales were also dented by a later Easter holiday, which is in April this year instead of March last year, and lower petrol prices.
Excluding these factors, like-for-like sales growth was 3.7 percent in the quarter, an acceleration from 3.2 percent growth in the fourth quarter 2013.
This was Carrefour's "best underlying quarterly sales growth performance in over two years", Sivignon said.
In France, which accounts for almost half of group revenues, same-store sales at Carrefour's hypermarkets rose 0.7 percent, a slowdown from a 1.4 percent rise in the fourth quarter 2013.
