MD&A
Text added vs the prior filing · source: 10-Q · 2026-07-30
The following tables present revenues and gross profit (loss) for the Company and its reportable segments by product line for the three months ended June 30, 2026 and 2025.
Second-quarter aggregates shipment increases were driven by organic growth, full-quarter contributions from the operations acquired in the QUIKRETE transaction and partial-quarter contributions from the New Frontier Materials (NFM) operations following the May 15, 2026 acquisition. Average selling p…
Other Building Materials revenues increased 12% to $303 million. Gross profit decreased 14% to $34 million due to higher ready mix concrete raw material costs combined with lower organic paving revenues and reduced job margins.
Specialties achieved second-quarter revenues of $152 million and gross profit increased 39% to $50 million. These results reflect contributions from the July 2025 Premier Magnesia, LLC acquisition and organic pricing gains across all products.
Consolidated SG&A for the second quarter of 2026 was 5.9% of revenues compared with 6.5% in the prior-year quarter as revenue growth outpaced the increase in these expenses.

Demand for our construction materials is inherently cyclical and may decline or become more volatile due to economic and political uncertainty, elevated interest rates and inflation, reduced housing affordability, lower private nonresidential investment, or tightening credit conditions that delay, d…
We sell most of our aggregates (our primary business) to the construction industry and, therefore, our results depend on that industry’s strength. Because our businesses depend on construction spending, which can be cyclical, our profits are sensitive to national, regional and local economic conditi…
The heavy-side construction business is conducted outdoors. Accordingly, our production, distribution, and customer demand are affected by seasonal weather patterns and adverse weather conditions. Adverse weather conditions, including hurricanes and tropical storms, extreme temperatures, snow, heavy…
Adverse weather conditions also increase our costs and reduce our production output as a result of power outage, additional plant and equipment repairs, the time required to remove water from flooded operations and similar events. Severe drought conditions can restrict available water supplies and c…
Production and shipment levels of the Building Materials business’ products follow activity in the construction industry, which typically is strongest in the spring, summer and fall. Because of the effect of the weather on the construction industry’s activity, our Building Materials business, includ…

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
