The revised schedule follows a special dividend ex-date announcement related to the merger.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Huron Consulting Group (HURN) will join the S&P SmallCap 600 before trading opens November 3, 2026, replacing Supernus Pharmaceuticals (SUPN).
The effective date moves from November 2 to November 3. Huron will enter the index in the Industrials sector. Indivior Pharmaceuticals (INDV), an existing index constituent, is acquiring Supernus in a transaction expected to close soon, subject to final closing conditions.
