Viavi Solutions Inc. transitioned from the S&P SmallCap 600 to the S&P MidCap 400 index. This change takes effect before the market opens on June 22, 2026. The promotion follows the quarterly S&P Dow Jones Indices rebalancing and highlights the company's market capitalization growth.

The inclusion in the mid-cap index aims to increase visibility among analysts and investors. Passive investment funds and ETFs tracking the S&P MidCap 400 must now purchase VIAV shares. This reclassification may trigger higher trading volumes and short-term price fluctuations.
