SKOKIE, Ill., June 29, 2026 (GLOBE NEWSWIRE) -- LanzaTech Global, Inc. (NASDAQ:LNZA) ("LanzaTech" or the "Company"), a carbon management solutions company, today announced that it has been added as a member of the Russell 3000® Index, effective at the open of the U.S. market on June 29, 2026, as part of the first 2026 Russell Indexes reconstitution.

LanzaTech’s inclusion in the Russell 3000® Index also places it in the Russell 2000® small-cap index, and potentially other relevant growth and value style indices based on fundamental metrics. Final index membership is expected to become effective after market close on Friday, June 26, 2026, subject to FTSE Russell’s final reconstitution schedule and updates. The Russell U.S. Indexes are widely utilized globally by institutional investors and investment managers for index funds, and as the primary benchmarks for active investment strategies.

Jennifer Holmgren, Chief Executive Officer of LanzaTech commented, "Our inclusion in the Russell 3000® index will serve as a meaningful step forward for the institutional visibility of the Company. We believe that this important milestone will increase the overall breadth of prospective institutional investors and allow us to tell our story to a wider universe within the investment community. We carry strong conviction in LanzaTech’s technology and our strategy, and we look forward to the opportunity to expand the market’s knowledge and understanding of our path to sustainable shareholder value creation as a leading global biomanufacturing platform and renewable fuels producer."

The June reconstitution of the Russell U.S. Indexes captures up to the 4,000 largest U.S. stocks as of April 30, ranked by total market capitalization. Beginning in 2026, index membership remains in place for six months under FTSE Russell’s semi-annual reconstitution schedule. FTSE Russell determines membership primarily by objective, market-capitalization rankings and style attributes.
