GFL ENVIRONMENTAL ANNOUNCES DENSIFICATION OF SOUTHERN US FOOTPRINT WITH THE ACQUISITION OF FRONTIER WASTE SOLUTIONS AND PROVIDES AN UPDATE ON YEAR-TO-DATE M&A ACTIVITY

GFL Environmental Inc. has closed the acquisition of Frontier Waste Solutions, a vertically integrated network of solid waste assets across 24 sites in Texas. The Frontier assets are supported by a fleet of over 650 vehicles and nearly 1,000 employees.

"We have admired watching Frontier grow into a leading regional business under CEO John Gustafson's leadership," said Patrick Dovigi, founder and chief executive officer of GFL. "John and the other Frontier shareholders have rolled $100-million (U.S.) of transaction proceeds into GFL shares, a testament to their belief in the future value creation opportunities of the combined businesses. We are excited that John and Frontier's other senior management will continue to lead the business going forward as both employees and shareholders of GFL."

Mr. Dovigi added: "The acquisition of Frontier provides a highly complementary set of assets that densifies our footprint and strengthens our presence in the Texas Triangle, one of the fastest-growing regions in the United States. The favourable market dynamics in this region combined with deep expertise of the Frontier management team are expected to drive outsized revenue growth over the coming years. The acquisition also enhances our ability to deliver reliable, essential services to the communities that we serve in this market."

Mr. Dovigi continued: "In addition to the acquisition of Frontier, since the start of the year we have completed seven other tuck-in acquisitions across multiple geographies, further densifying our existing footprint. Together, these acquisitions are expected to contribute $425.0[-million] to $450.0-million in aggregate annualized revenue."

Mr. Dovigi concluded: "We continue to demonstrate our ability to successfully execute our growth strategy of pursuing strategic and accretive acquisitions. With the transactions closed to date, we are positioned to meaningfully increase our guidance for 2026 when we report our first quarter results later this month. Furthermore, the strength of our balance sheet and our industry-leading organic growth allow us to deploy capital into these acquisitions while maintaining our 2026 net leverage target of low to mid 3s."

GFL financed the acquisitions completed year to date through its credit facility, cash on hand and the issuance of 2,582,463 subordinate voting shares as partial consideration for the acquisitions.
