MANAGEMENT COMMENTARY

“We had a good start to 2026, improving year-over-year revenue by 16%, adjusted EBITDA by 16% and adjusted EBITDA margin by 290 basis points,” said Knife River President and CEO Brian Gray. “We realized double-digit volume increases across our product lines and we reduced our per-unit costs, which drove gross profit improvements for aggregates, ready-mix and asphalt. We also generated more contracting services revenue than the same time last year, taking advantage of better weather and more activity across our segments.

“Knife River states are enjoying some of the fastest population growth in the nation, and we are growing our business along with them,” Gray said. “We completed three acquisitions during the quarter: Morgan Asphalt in Utah; and Sparrow Enterprises and Donaldson Brothers Ready-Mix in Montana. These aggregates-based, vertically integrated additions to our Mountain Region align with our strategy of expanding into mid-sized, higher-growth markets.

“While the first quarter is seasonally the lightest activity period of the year, we enter the 2026 construction season with momentum, including record first quarter backlog of $1.2 billion,” Gray said. “With strong underlying demand, our recent acquisitions, and continued focus on price optimization and cost controls — including mitigating energy costs with our established operational practices — we expect to deliver profitable growth for our shareholders this year and beyond.”
