“We are pleased and proud to report that our teams safely and successfully managed through weather-related disruptions to deliver a strong quarter of strategic execution and solid financial results,” remarked Anne Noonan, Summit Materials president and CEO. “Our resilient performance was supported by positive pricing momentum across all lines of business, ongoing cost savings initiatives underway across our network, and a more durable portfolio. As a result, our 2024 financial targets are virtually unchanged. Namely, we are still on track to generate at least $40 million of Argos USA synergies, drive significant pro forma margin expansion this year, and confidently deliver 2024 Adjusted EBITDA within our previous guidance range. Without question, Summit Materials is well positioned to capitalize on a constructive pricing environment and tap operation improvements across our enterprise to profitably grow in an uneven demand environment. This growth, together with a fortified and capable balance sheet will help generate significant shareholder value this year and the years ahead. Our team remains focused on controlling what we can, acting with agility, and delivering on all of our 2024 stakeholder commitments.”
