• Kicked off the year with strong results, made progress on strategic transformation, and increased full year guidance for continuing operations. • Delivered adjusted EBITDA growth of 10% from continuing operations, double revenue growth, and expanded margin by 100 basis points. • Completed $450 million barge divestiture on April 1st, a pivotal step in simplifying portfolio. • In March, completed $60 million acquisition of a natural aggregates operation in Florida. • Balance sheet in great shape, pro forma for barge divestiture net debt to adjust to the beta decreased to 1.9 times. • Full year 2026 guidance now reflects continuing operations only, expecting adjusted EBITDA of $565 million at midpoint, up $22.5 million from previous guidance range. • Construction products demand outlook broadly consistent, with new uncertainty from Middle East conflict not translating to weaker demand in construction footprint. • Engineered structures' utility structures performance exceeded expectations, momentum building, and raised expectations for the balance of the year. • Generated $58 million of operating cash flow from continuing operations during the quarter, free cash flow from continuing operations was $21 million up from negative $49 million in prior period. • Full-year CapEx expected to be $215 million to $240 million, effective tax rate expected to be 16% to 18%, corporate cost impact to adjusted EBITDA approximately $60 million at midpoint of guidance range.

• Full year 2026 guidance now reflects continuing operations only, expecting adjusted EBITDA of $565 million at midpoint, up 11% year over year. • Anticipate revenues of $2.65 billion at midpoint, up 6% year-over-year. • Expect margin to expand to a record 21.3%. • For construction products, anticipate another record year of revenues and adjusted segment EBITDA, mid-single-digit adjusted EBITDA growth. • For aggregates, incorporating low single-digit volume growth and mid-single-digit pricing improvement. • Full-year CapEx expected to be $215 million to $240 million, a slight reduction from prior range. • Effective tax rate expected to be 16% to 18%, down 1.5 points due to lower expected state tax rate for continuing operations. • Corporate cost impact to adjusted EBITDA approximately $60 million at midpoint of guidance range, roughly flat with 2025.

For continuing operations: Construction products - first quarter results finished largely in line with expectations, overcoming a slow start due to severe winter weather. Segment revenues increased 5% and adjusted segment EBITDA decreased slightly. Aggregates: freight adjusted revenues increased roughly 6% (2% pricing growth and 4% volume), adjusted cash gross profit margin increased 220 basis points, and adjusted cash gross profit per ton increased 7%. Specialty materials and asphalt: revenues decreased 4% (primarily due to lower asphalt volumes), costs were higher year over year, resulting in lower adjusted EBITDA for the quarter. Trench shoring: completed another strong quarter of growth with both revenues and adjusted EBITDA up about 26%. Engineered structures: segment revenues increased 4%, led by mid-teen growth in utility and related structures businesses. Utility structures revenue accelerated north of 15%, significant margin expansion drove a 21 percent increase in adjusted segment EBITDA, segment margin increased to a record 21.1 percent. Ended the quarter with record backlog for utility and related structures of $558 million, up 28% from the start of the year. Wind towers: received orders of $43 million during the quarter for delivery in 2026 and 2027, ended the quarter with backlog of $600 million and expect to recognize 36% in 2026 and 59% in 2027.

Q: On utility structures and engineered structure segment overall, what's driving margin strength and sustainability?

A: Margin strength mainly driven by utility structures. Utility structures revenues went up over 15% in the quarter, margins extremely strong. Team performed well, volumes up and capacity tweaked. Wind side expected to be transition year, but utility structures expected to continue performing and accelerate. Margin expectation for the segment has increased, seeing annual margin in 20% range sustainable.

Q: On customer reservations for utility structures and high return investments related to capacity?

A: Customer reservations normally grow in parallel with backlog. Very strong demand and customer sentiment. High return investments include conversion of Illinois wind tower plant to utility pole plant, new galvanizing facility in Mexico, and planning for transition of second wind tower facility in Oklahoma to produce utility poles.

Q: On cost outlook, energy exposure in construction products and other inflationary inputs?

A: In construction products, using 10 - 11 million gallons of diesel. Passing through fuel surcharges and loading fees to mitigate impacts. In utility structures and wind, impact negligible. Diesel prices up about $1.50 a gallon in aggregates footprint, estimated 4% - 5% headwind to cash unit profitability for 2026 if prices remain elevated. Asphalt projects indexed to liquid AC costs.

Q: On tail of utility power demand and confidence in raising guide?

A: Raising guide due to good performance and backlog in place. Confidence comes from long-term forecast of investment by utilities in grid, AI supercharging demand for transmission towers, and market studies supporting expansions.

Q: On capability to produce 765 kV transmission lines and prioritization of incremental cash?

A: Have engineering capability to produce 765 kV transmission lines, working on it. Prioritization: M&A in natural and recycled aggregates as main inorganic priority, organic growth in utility structures. Share repurchases opportunistic to compensate for compensation dilution, no plans to increase dividends.
