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. (TSX: CURA) (OTCQX: CURLF) ("Curaleaf" or the "Company"), a leading international provider of consumer cannabis products, today announced that it has been added to the FTSE Canada All Cap Index, effective after the close of trading on Friday, September 18, 2026.

Joining the FTSE Canada All Cap Index now puts Curaleaf in a second major Canadian benchmark," said Boris Jordan, Chairman and CEO of Curaleaf.

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.
