GFL ENVIRONMENTAL JOINS THE RUSSELL 1000(TM) AND RUSSELL 3000(TM) INDICES

GFL Environmental Inc. has been added as a member of the U.S. large-cap Russell 1000 Index and the broad-market Russell 3000 Index, effective as at the opening of the United States equity markets on June 29, 2026. The inclusion comes as part of the 2026 Russell Index Reconstitution, which captures the 4,000 largest U.S. stocks ranked by total market capitalization.

Earlier this year, the company relocated its executive headquarters to Florida to align with its expanding presence in the Southeastern region of the United States and to gain broader index inclusion. Today's announcement is a direct benefit of those actions.

"Our inclusion in the Russell 1000 Index is a testament to the success of GFL's growth strategy," said Patrick Dovigi, founder and chief executive officer of GFL. "It unlocks immediate access to a significantly wider base of global passive and active investors, while preserving our eligibility for inclusion across Canadian equity indices."

Mr. Dovigi continued: "This milestone is an initial step in increasing our market visibility. We plan to implement additional strategic initiatives to further expand our index inclusion eligibility, which we believe will result in even broader inclusion across additional major North American indices."

The Russell U.S. Indexes are extensively used by investment managers, pension funds and exchange-traded funds as benchmarks for investment decisions and portfolio construction, with approximately $12.2-trillion (U.S.) in assets benchmarked against them as of June, 2025. FTSE Russell determines Russell Index membership based on objective, rules-based market-capitalization rankings and style attributes.
