Almonty
Industries Joins Large-Cap Russell 1000® Index and Broad-Market Russell 3000® Index
Dillon,
MT – June 29, 2026 – Almonty Industries Inc. (“Almonty” or the “Company”) (NASDAQ: ALM) (TSX:
AII) (ASX: AII) (Frankfurt: ALI1), a leading global producer of tungsten concentrate, today announced that it has joined the large-cap
Russell 1000® Index and the broad-market Russell 3000® Index, effective with the opening of United States equity markets today,
Monday, June 29, 2026, upon the conclusion of the 2026 Russell indexes reconstitution.
The
June 2026 reconstitution of the Russell U.S. Indexes captures the 3,000 largest U.S. stocks, ranking them by total market capitalization.
The Russell 1000® Index, which is a subset of the Russell 3000® Index, is a U.S. stock market index that tracks the 1,000 largest
publicly traded companies in the U.S. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization
rankings and style attributes.
Lewis
Black, Chairman, President and Chief Executive Officer of Almonty Industries, commented: “Given the FTSE Russell builds these indexes
on objective, market-capitalization criteria, qualifying for the Russell 1000® and Russell 3000® is a milestone Almonty earned
on the numbers, not by invitation. To us, it signals that the market now recognizes the scale we have reached as a Western-aligned producer
of a metal that the defense and advanced-technology sectors cannot do without. Just as important, index membership connects Almonty with
the large universe of index-tracking funds and benchmark-driven institutions that allocate to Russell constituents, many of which were
unable to hold our shares before today. We view that as the basis for steadier trading liquidity and a more durable base of long-term
shareholders.”
Russell
indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies.
According to data as of the end of June 2025, approximately $12.2 trillion in assets are benchmarked against the Russell U.S. indexes,
which belong to FTSE Russell, the global index provider. For more information on the Russell 1000® and the Russell 3000® Indexes

About
Almonty Industries Inc.
Almonty
(Nasdaq: ALM) (TSX: AII) (ASX: AII) (Frankfurt: ALI1) is a leading supplier of conflict free tungsten – a strategic metal critical
to the defense and advanced technology sectors. As geopolitical tensions heighten, tungsten has become essential for armor, munitions,
and electronics manufacturing. Almonty’s flagship Sangdong Mine in South Korea, historically one of the world’s largest and
highest-grade tungsten deposits, is expected to supply a significant portion of global non-China tungsten production upon reaching full
capacity, directly addressing critical supply vulnerabilities highlighted by recent U.S. defense procurement bans and export restrictions
by China. With established operations in Portugal and additional projects in Spain and the United States, Almonty is strategically aligned
to meet rapidly rising demand from Western allies committed to supply-chain security and defense readiness. To learn more, please visit
