Perma-Pipe International Holdings, Inc. (NASDAQ:PPIH) announced today that it has been added as a member of the Russell 2000® and the Russell 3000® indexes, effective when the US market opens on June 29, as part of the first 2026 Russell indexes reconstitution.

The June reconstitution of the Russell US indexes captures up to the 4,000 largest US stocks as of April 30, ranking them by total market capitalization. Membership in the Russell 3000® Index, which remains in place for half a year beginning 2026, means automatic inclusion in the large-cap Russell 1000® Index or small-cap Russell 2000® Index as well as the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.

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, about $12.2 trillion in assets are benchmarked against the Russell US indexes, which belong to FTSE Russell, the global index provider. For more information on the Russell 2000 and 3000 Indexes and the Russell indexes reconstitution, go to the "Russell Reconstitution" section on the FTSE Russell website.

"Our inclusion in the Russell 2000 and Russell 3000 indexes is a meaningful milestone for Perma-Pipe and a reflection of the progress we have made in growing the Company and creating value for our shareholders," said Saleh Sagr, President and Chief Executive Officer of Perma-Pipe.
