MindWalk Holdings Corp. (NASDAQ: HYFT) Added to the Russell 3000E Index, Expanding Institutional Investment Opportunity

Inclusion in FTSE Russell's June 2026 semi-annual reconstitution expands visibility among institutional investors and broadens eligibility for index-tracking funds managing more than $12 trillion in benchmarked assets

AUSTIN, Texas--(BUSINESS WIRE)--MindWalk Holdings Corp. (“MindWalk”) (NASDAQ: HYFT), a Bio-Native AI company, today announced that it has been added to the Russell 3000E Index, effective after the U.S. market close on June 26, 2026, as part of the FTSE Russell June 2026 semi-annual Russell US Indexes Reconstitution. Membership was reconfirmed in index data published June 29, 2026.

The Russell 3000E Index is FTSE Russell's broadest measure of the U.S. equity market, covering up to the 4,000 of the largest U.S.-domiciled public companies by market capitalization. Inclusion is determined, and since 2026 reconfirmed on a semi-annual basis in June and December, using market capitalization as of the rank date, with no application or fee required.

“Being added to the Russell 3000E Index is a meaningful visibility milestone in MindWalk’s evolution as a public company. It places us in front of a broader set of institutional investors and index-tracking funds that had no mechanism to consider MindWalk before. We see this as one more signal that the market is starting to price the infrastructure layer beneath biological AI, not just the AI models running on top of it. ”

— Jennifer Bath, Ph.D., Chief Executive Officer and President, MindWalk Holdings Corp.

According to FTSE Russell, approximately USD 12.2 trillion in investor assets are benchmarked to, or invested in products based on, the Russell US Indexes.¹ Membership in the Russell 3000E Index means passive funds and other vehicles that track the index, or broader benchmarks built from it, are eligible to hold MindWalk shares as part of their standard rebalancing, without any action required by the Company.

Russell index membership and associated indexes are calculated by FTSE Russell. For more information on the Russell indexes, methodology, and the full 2026 reconstitution results, visit ftserussell.com.
