Lumentum promoted from S&P MidCap 400 to S&P 500 index
Lumentum Holdings Inc of San Jose, CA (which designs and makes photonics products for optical networks and lasers for industrial and consumer markets) has been selected to join the S&P 500 index. According to S&P Dow Jones Indices, Lumentum will be added to the benchmark index before the market opens on 23 March.
Lumentum says that the transition marks a significant milestone as it moves from the S&P MidCap 400 to the S&P 500, reflecting its substantial growth and corresponding increase in market capitalization.
“It reflects our vital role in helping customers build next-generation AI infrastructure,” says president & CEO Michael Hurlston. “By deepening our strategic partnerships and increasing capacity for advanced photonics, we continue to deliver long-term value to both our customers and shareholders.”
Promotion of a company from the S&P MidCap 400 to the S&P 500 is a widely recognized hallmark of corporate maturity and financial health, notes Lumentum. Beyond providing increased liquidity and market visibility, inclusion in the S&P 500 places it among the 500 leading companies in the USA.
