Mtron Added to Membership of Russell 3000® Index

ORLANDO, Fla., July 1, 2025 /PRNewswire/ -- M-tron Industries, Inc. (NYSE American: MPTI) ("Mtron" or the "Company"), a leading provider of high-performance radio frequency components and solutions, today announced the Company was added as a member of the broad-market Russell 3000^® Index, effective after the U.S. market close on June 27, 2025.

The annual reconstitution of the Russell US indexes captures 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 one year, 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.

"Our inclusion in the Russell 3000® Index is a meaningful milestone that reflects the strong progress we've made since our IPO in October 2022," said Cameron Pforr, Interim CEO. "In less than three years as a public company, we've delivered consistent growth, expanded our market presence, and continued to execute on our long-term strategic vision. Being recognized alongside other leading U.S. companies is a testament to the dedication of our team and the confidence our investors have placed in us. We look forward to building on this momentum as we continue to drive value for our 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 2024, about $10.6 trillion in assets are benchmarked against the Russell US indexes, which belong to FTSE Russell, the global index provider.
