Lumentum Holdings Inc. ("Lumentum"), a market-leading designer and manufacturer of innovative optical and photonic products, today announced that it has received the EcoVadis Platinum Medal for the second consecutive year, representing the highest level of recognition for sustainability performance. Lumentum remains in the top one percent of companies assessed by EcoVadis in the past year, increasing its overall score from 78 to 80 points. In the environmental category, the company increased its score by 10 points from last year. Medals are awarded based on the percentile rank of a company compared to the performance of all rated companies.

"This achievement reflects our efforts to integrate sustainable practices across all of our operations. We are dedicated to pushing the boundaries of what is possible, driving both technical innovation and operational advancements that serve our customers and create a positive impact on our planet and communities."

"We have continuously improved our sustainability efforts every year and it is a major accomplishment to be recognized among the elite top one percent for our environmental initiatives for two consecutive years," said Misha Rozenberg, senior vice president of Global Operations and chief quality officer at Lumentum. "We couldn't have achieved this prestigious recognition without the hard work and close collaboration of many teams across Lumentum."
