Flowserve Awarded "Certified Supplier” Seal of Approval from Nuclear Energy Company, AREVA

Flowserve Corporation (NYSE: FLS), a leading provider of flow control products and services for the global infrastructure markets, today announced it received the "AREVA Certified Supplier” award and seal of approval. Flowserve President and Chief Executive Officer Lewis Kling accepted the recognition from AREVA Chief Executive Officer Anne Lauvergeon in a Washington, D.C., ceremony on Thursday, June 4.

Speaking at the award ceremony, Kling said, "This award from AREVA symbolizes the importance of serving our customers with comprehensive fluid motion and control products and solutions. In addition to Flowserve’s global footprint, our customer-centric culture helps our customers achieve their business goals.”

To promote the companies that support its growth, AREVA created the certification program to give greater visibility to the quality of its relationships with suppliers.

"Maintaining trusting, long-term relations with suppliers has been one of the keys to AREVA’s success, which is why we wish to thank them and renew this trust by giving them the title of ‘AREVA Certified Supplier,’” Lauvergeon said.

A company can become an "AREVA Certified Supplier” by meeting 25 objective criteria, including quality, sustainable development values and competitiveness. Other decisive areas include investment in innovation and R&D, and the attention to nuclear/occupational safety and the environment.

Flowserve has a long-standing relationship with AREVA.
