When the index change takes effect
S&P Dow Jones Indices announced on November 11 that Ingram Micro Holding Corp. will replace Pacira BioSciences in the S&P SmallCap 600 before the opening of trading on Tuesday, November 17, 2026. Ingram Micro trades on the New York Stock Exchange as INGM; Pacira trades on Nasdaq as PCRX.
The index provider lists Ingram Micro in the Information Technology sector and Pacira in Health Care. The effective date is the scheduled change to index membership, rather than a new stock-market listing.
Why Pacira is leaving
The announcement links Pacira’s removal to its planned acquisition by Viatris, an S&P 500 constituent. S&P says that transaction is expected to close soon, subject to final closing conditions.
That statement does not establish that the acquisition has already closed or give November 17 as its closing date. The confirmed November 17 timing concerns the S&P SmallCap 600 replacement.
Which index is involved
The change concerns the S&P SmallCap 600. Viatris’s separate S&P 500 membership should not be read as an announcement that Ingram Micro is entering the S&P 500.
Readers tracking an index-linked holding or company reference can check the provider’s effective-date notice. The announcement does not establish a future share-price move or investment return.
