Vusion shares plunged 12% after announcing a strategic partnership with Carrefour to deploy its technologies across French stores by 2030. Carrefour shares also dropped more than 5% following weaker-than-expected fourth-quarter sales in France. The European retailer's like-for-like sales rose just 0.4%, below analysts' 0.7% forecast, while recurring operating income missed estimates.

The agreement, unveiled during Carrefour's Capital Markets Day, covers €150 million investment for Electronic Shelf Labels using Vusion's EdgeSense technology and AI-powered computer vision services. Analyst Valentin-Paul Jahan described the partnership as fundamentally positive, highlighting Vusion's technological relevance. EdgeSense, currently deployed at Walmart in the U.S., aims to automate pricing and optimize in-store operations.

Jahan estimates the agreement could generate more than €30m in annual revenue for Vusion, with the computer-vision component targeting a 20% reduction in out-of-stock situations. However, the analyst noted limited visibility for 2027 performance as Walmart's U.S. deployment ends. Carrefour's new strategy focuses on core markets of France, Spain and Brazil, targeting 3.5% operating margin by 2030 and €1 billion in annual cost savings.
