Curaleaf Holdings, Inc. Investor Relations Curaleaf Added to FTSE Canada All Cap Index This addition marks the second major Canadian benchmark inclusion following the Company's addition to the S&P/TSX Composite Index in 2025 STAMFORD, Conn., Sept. 23, 2026 /PRNewswire/ -- Curaleaf Holdings, Inc.

The FTSE Canada All Cap Index, maintained by FTSE Russell, measures the performance of large-, mid- and small- capitalization companies listed in Canada. This is the second major Canadian index fund Curaleaf has joined since the company was added to the S&P/TSX Composite Index under the Health Care sector in September 2025.
