Sirius XM Holdings Set to Join S&P MidCap 400

On June 11, 2026, Sirius XM Holdings Inc. (NASDAQ: SIRI) will officially replace Masimo Corp. (NASDAQ: MASI) in the S&P MidCap 400 index. This transition comes in the wake of significant market developments, particularly as Danaher Corporation (NYSE: DHR) is poised to acquire Masimo in a deal expected to finalize soon, contingent upon meeting certain conditions.

Details of the Change

The action is effective prior to the opening of trading on the specified date, marking a notable shift in the index. Sirius XM's addition to the S&P MidCap 400 signifies its growing prominence in the communication services sector, where investors are increasingly looking for reliable sources of revenue in both broadcasting and digital media content.

In contrast, Masimo’s removal highlights the impact of corporate transactions on market placements. Observers note that such changes in indices can influence stock prices and investor perceptions, making it essential for companies engaged in mergers and acquisitions to consider their index standings carefully.
