S&P BMI Index Changes

S&P Global Inc. · 2026-09-09 · Importance 3 · Surprise 6

AtaiBeckley Inc. was removed from the S&P Global BMI Index effective following the September 8, 2026 announcement. The index change came after multiple analyst downgrades from Oppenheimer, Deutsche Bank, TD Cowen, Berenberg, Canaccord Genuity, and Jefferies. The company had also been subject to a July rumor that Biotech Growth was positioning it for an Eli Lilly takeover, although that rumor was not identified as the reason for the index removal.
