### Business Model

- **[CATALYST] Building Materials And Aggregates M&A and Portfolio Action** (NEGATIVE, Change: CONTRACTING): Concrete was the fastest-growing operating segment in Q3 FY25. Segment sales rose 36.2%, shipments rose 33.3%, and gross profit more than doubled. Its revenue share increased to approximately 10.4% from approximately 8.7%. The improvement benefited from acquired operations. (3 expanding, 2 contracting across 1 engine)
  > Concrete 186.8 220.6 ... Gross Profit ... Concrete 8.4 8.5
- **[METRIC] Building Materials And Aggregates Balance Sheet Resilience** (NEUTRAL): Vulcan's balance sheet supports continued investment and acquisitions through the construction cycle. At June 30, 2026, total debt was $4,364.3 million, net debt was $4,075.6 million, and net debt was 1.7 times trailing-twelve-month Adjusted EBITDA. The company had $1,581.5 million of available bank-line capacity, no commercial paper outstanding, and an average debt maturity of 13.2 years. This financial flexibility is useful in a capital-intensive quarry business, although the company still carries significant debt and a $400.0 million maturity due in the second quarter of 2027.
  > At June 30, 2026, total debt to trailing-twelve months Adjusted EBITDA was 1.9 times (1.7 times on a net debt basis reflecting $288.7 million of cash on hand). Our weighted-average debt maturity was 13.2 years ... As of June 30, 2026, our available borrowing capacity under the line of credit was $1,
- **[METRIC] Building Materials And Aggregates Margin Profile** (POSITIVE, Change: EXPANDING): Aggregates profitability strengthened materially. Gross margin increased to 34.2% from 31.7%, while gross profit per ton increased to $9.46 from $8.63. Freight-adjusted price rose 3.5% and unit cost declined 1%, showing both pricing and operating leverage. (5 expanding across 1 engine)
  > Asphalt $ 330.0 $ 368.9 ... Gross Profit ... Asphalt 49.8 57.2
- **[METRIC] Building Materials And Aggregates Revenue Growth** (POSITIVE, Change: EXPANDING): Aggregates remained the dominant revenue and profit engine and expanded year over year. Segment sales rose 14%, shipments rose 12%, and gross profit rose 23%. Its share of consolidated revenue was approximately 78.2% in Q3 FY25, up from approximately 78.1% in Q3 FY24, effectively stable to slightly expanding. Unit profitability also improved, with gross profit per ton rising 9.6%. (5 expanding across 1 engine)
  > Aggregates $ 1,763.0 $ 1,649.6 ... Gross Profit ... Aggregates $ 567.3 $ 559.5 ...
- **[PRINCIPLE] Building Materials And Aggregates Unit Economics** (POSITIVE, Change: EXPANDING): Aggregates profitability per ton continued to expand, showing that growth was not merely the result of higher volume. Gross profit per ton increased 5% in 2025 and cash gross profit per ton increased 7%. (2 expanding)
  > Aggregates segment gross profit increased 8% to $1,964.8 million (or $8.66 per ton)... Cash gross profit per ton increased 7% from the prior year to $11.33.
- **[PRINCIPLE] Building Materials And Aggregates Competitive Moat** (POSITIVE, Change: EXPANDING): The scale moat strengthened through the 2024 acquisitions and higher shipment volumes. Identifiable assets increased 20.8% year over year to $16.4 billion, while aggregates assets increased 20.9% to $14.5 billion. The larger asset and operating footprint supports service to major metropolitan and long-haul markets. (3 expanding)
  > We are the nation's largest supplier of construction aggregates ... We serve these markets from quarries that have access to cost-effective long-haul transportation, including shipping by barge, rail and our fleet of Panamax-class, self-unloading ships.
- **[PRINCIPLE] Building Materials And Aggregates Regulatory Position** (NEUTRAL): Zoning, mining permits, environmental approvals, reclamation obligations, and mine-safety requirements make it difficult and slow to open competing quarries. These rules do not give Vulcan unlimited pricing power, but they restrict new supply in many local markets and protect the value of permitted reserves.
  > Due to zoning and permitting regulations and high transportation costs relative to the value of the product, the location of reserves is a critical factor to our long-term success.
- **[PRINCIPLE] Building Materials And Aggregates Revenue Quality** (NEGATIVE, Change: CONTRACTING): Service revenue expanded faster than total revenue in Q3 FY25, rising 18.7% and increasing slightly as a share of revenue. It remains a small supplemental stream from paving and aggregates-related services rather than a core earnings engine. (2 expanding, 1 contracting across 1 engine)
  > Our total service revenues were $71.8 million (3.3% of total revenues) and $87.9 million (4.2% of total revenues) for the three months ended June 30, 2026 and 2025, respectively.
- **[TREND] Building Materials And Aggregates Demand Cycle** (NEUTRAL, Change: SHIFTED): The Gulf Coast remained the largest geographic market and expanded 12.5% year over year. Its share of consolidated revenue was approximately 45.9%, broadly stable versus approximately 46.7% in Q3 FY24. Growth was driven mainly by aggregates and asphalt. (2 expanding, 1 contracting)
  > East revenues $ 537.2 $ 59.4 $ 89.2 $ 685.8

### Future Growth

- Q2 cash profit per ton increased to $12.02 while average price rose 3.9% and cash cost excluding diesel rose 3%, indicating Vulcan retained pricing power despite cost pressure. If this spread persists, profit can grow faster than shipments and support earnings expansion. (POSITIVE)
- **[CATALYST] Building Materials And Aggregates Earnings and Guidance Reset** (NEUTRAL, Trend: STEADY): Management reduced its full-year 2024 Adjusted EBITDA expectation to approximately $2.0 billion because of lower shipments and continued weather disruption. This is a guidance reset from the stronger prior operating trajectory, although management still expects pricing and demand fundamentals to support volume growth in 2025. (1 decelerating, 4 steady across 5 signals)
  > Our aggregates business is executing well, and we reiterate our full-year outlook to deliver between $2.4 and $2.6 billion of Adjusted EBITDA. The construction environment remains supportive of continued aggregates price growth, and large projects and public construction activity continue to support
- **[CATALYST] Building Materials And Aggregates M&A and Portfolio Action** (NEGATIVE, Trend: REVERSING): The company continued concentrating on aggregates, with the Texas concrete divestiture already completed before Q1 2024. Concrete segment revenue fell from $285.1 million to $148.3 million year over year, primarily because of that divestiture, while aggregates revenue remained broadly stable and asphalt revenue increased. This is a strategic portfolio shift, not an accelerating revenue signal; downstream concrete revenue has structurally reversed lower. (2 reversing, 1 decelerating, 2 new trend across 5 signals, 1 leading indicator)
  > The pipeline for strategic acquisitions remains active, and we have the financial strength and flexibility to capitalize on the most value-accretive opportunities.
- **[CATALYST] Building Materials And Aggregates Product or Capex Inflection** (POSITIVE, Trend: ACCELERATING): Vulcan is increasing investment in its core aggregates network. Q1 2026 capital spending was $90.4 million, including $73.4 million in aggregates, while the supplied prior signal reports H1 2026 spending of $370.4 million and $225.2 million directed to aggregates, up from $179.6 million a year earlier. The direction is positive and accelerating in absolute investment, although the periods are not directly comparable because one is quarterly and the other is half-year. (2 accelerating, 3 decelerating across 5 signals, 2 leading indicators)
  > During the first six months of 2026, we invested $370.4 million in our existing operations ... This $370.4 million investment includes both maintenance and internal growth projects to enhance our distribution capabilities, develop new production sites and improve existing production facilities.
- **[METRIC] Building Materials And Aggregates Margin Profile** (NEGATIVE, Trend: DECELERATING): Unit profitability improved in Q1 2026: cash gross profit per ton rose 2.8% to $10.93, while GAAP gross profit per ton rose 7.1% to $8.01. The supplied prior signal reports Q2 cash gross profit per ton of $12.02, up 1.2% year over year. Profit per ton is still growing, but the growth rate slowed from Q1 to Q2, making the trend decelerating rather than accelerating. (1 decelerating, 1 steady across 2 signals)
  > Cash gross profit per ton 10.93 10.63... Gross profit per ton $8.01 $7.48.
- **[METRIC] Building Materials And Aggregates Revenue Growth** (NEGATIVE, Trend: REVERSING): The latest available quarter shows strong price-led aggregates growth, but the trajectory is not directly comparable with the previously extracted 2026 figures because this filing covers Q2 2024. In Q2 2024, sales increased 2% while shipments fell 5%; the freight-adjusted price rose 12.2%. Growth is therefore coming mainly from pricing rather than volume. Compared with the first-half figures, the quarterly price increase was faster than the 11.3% year-to-date increase, suggesting recent pricing momentum is accelerating, while volume remains weak. (2 accelerating, 3 reversing across 5 signals)
  > Aggregates segment sales increased $113.4 million, or 7%, to $1,763.0 million ... Shipments increased 1%, or 0.6 million tons, to 59.9 million tons ... Freight-adjusted sales price increased 3.9%, or $0.86 per ton, to $22.97 ... large projects and public construction activity continue to support our
- **[METRIC] Building Materials And Aggregates Unit Economics** (NEGATIVE, Trend: DECELERATING): Aggregates cash gross profit per ton increased 10% year over year to $8.86 in Q1 2024, while GAAP gross profit per ton increased 8% to $6.30. Management also states that unit cash costs increased 9% on a trailing-twelve-month basis, marking the fourth consecutive quarter of cost deceleration. This indicates healthy unit-profit expansion despite lower shipments, although only one quarterly profit-per-ton point is disclosed here. (4 accelerating, 1 decelerating across 5 signals)
  > Continued pricing discipline and operational execution drove earnings growth ... second quarter Aggregates segment gross profit increased 1% to $567.3 million ($9.47 on a per ton basis), and cash gross profit improved to $720.1 million ($12.02 on a per ton basis) ... Excluding the impact of higher d
- **[PRINCIPLE] Building Materials And Aggregates Capital Allocation** (NEUTRAL, Trend: STEADY): The portfolio shift toward aggregates is continuing. Vulcan completed the prior-year sale of Texas concrete operations, and no significant divestitures occurred in the first nine months of 2024. At the same time, new acquisitions were concentrated in aggregates, asphalt and paving. This indicates a steady, aggregates-focused capital allocation strategy rather than a newly accelerating divestiture program. (1 steady across 1 signal)
  > We had no significant divestitures through the nine months ended September 30, 2024.
- **[TREND] Building Materials And Aggregates Demand Cycle** (NEGATIVE, Trend: DECELERATING): First-half aggregates sales grew only 1% because a 6% shipment decline offset an 11.3% price increase. The latest quarter was somewhat better on sales growth, at 2%, but still had a 5% shipment decline. This indicates a price-led recovery with volume still constrained by weather, rather than broad-based demand acceleration. (1 decelerating, 1 reversing across 2 signals)
  > Aggregates segment sales for the first six months of 2026 were $3,213.5 million (up 8%), and shipments increased 3%, or 2.9 million tons, compared to the prior year ... Freight-adjusted selling prices increased 3.7% compared to the prior year.
- **[TREND] Building Materials And Aggregates Supply Chain Reconfiguration** (NEUTRAL): Growth could be slowed by severe weather, energy inflation, tariffs, geopolitical disruption and labor shortages. In Q2, heavy rainfall affected Texas and some Southeastern markets, while higher diesel costs pushed unit costs up 7%. These are current constraints, with potential to reduce shipment volumes or delay construction activity. — Weather, energy, labor and macroeconomic pressures: Potential negative impact on shipment volumes; quantified unit cost increase of 7% YoY
  > Shipments in Texas and certain Southeastern markets were impacted by significant rainfall, particularly in May and June ... freight-adjusted unit cost of sales increased 7% ... Inflationary pressures and labor constraints can be factors that impact our operations ... geopolitical conflict ... has le

### Risk Assessment

- Energy and fuel inflation remain a direct threat to profit per ton. If diesel, electricity, labor, or freight costs rise faster than Vulcan can implement price increases, unit economics will deteriorate. (NEUTRAL)
- **[CATALYST] Building Materials And Aggregates US Policy Change** (NEUTRAL, Risk: MODERATE): Tariff changes and geopolitical conflict could raise energy and supply-chain costs and weaken customers' construction budgets. The filing does not identify a direct Chinese dumping exposure, but broader trade restrictions could still affect imported equipment, fuel-related costs, and customer demand. [REGULATORY]
  > Our industry is experiencing uncertainty due to rapid changes in global trade policies including announced tariff increases, potential additional tariff increases, potential new or renegotiated bilateral or multilateral trade agreements, and other measures that could restrict international trade. Ad
- **[METRIC] Building Materials And Aggregates Balance Sheet Resilience** (NEUTRAL, Risk: MODERATE): Liquidity is adequate today, but the company has substantial debt and a $400 million maturity due in the second quarter of 2027. A downturn in construction or weaker cash generation could make refinancing or debt repayment more expensive. [BALANCE_SHEET]
  > At June 30, 2026, total debt to trailing-twelve months Adjusted EBITDA was 1.9 times (1.7 times on a net debt basis reflecting $288.7 million of cash on hand). ... The $400.0 million of current maturities of long-term debt as of June 30, 2026 is due as follows: ... Second quarter 2027 400.0
- **[METRIC] Building Materials And Aggregates Free Cash Flow** (NEUTRAL, Risk: MODERATE): Cash available for investment and shareholder returns is less than reported operating cash flow after capital spending. Heavy capital needs, dividends, and buybacks could reduce flexibility during a downturn, especially because 2026 capital spending increased sharply. [BALANCE_SHEET]
  > Net cash provided by operating activities was $584.6 million during the six months ended June 30, 2026... During the first six months of 2026, we invested $370.4 million in our existing operations... during the first six months of 2026 we returned $535.2 million to shareholders through $135.4 millio
- **[METRIC] Building Materials And Aggregates Margin Profile** (NEGATIVE, Risk: HIGH): EASING. The older comparison period had lower margins and an $86.6 million impairment charge. In Q3 FY25, consolidated gross margin increased to 30.4% from 28.2%, while aggregates gross margin rose to 34.2% from approximately 31.7%. Aggregates gross profit per ton increased 10% to $9.46, and cash gross profit per ton increased 9% to $11.84. Margin risk remains because management expects continued inflation and relies on further pricing growth, but the latest direction is favorable. (2 easing, 3 intensifying, 1 high-severity)
  > Gross profit margin 29.0% 29.7% ...
- **[METRIC] Building Materials And Aggregates Revenue Growth** (NEGATIVE, Risk: HIGH): Recent operating data already shows weakness outside the core aggregates business. Lower asphalt and concrete volumes can reduce profit, particularly if fixed plant and labor costs remain in place. [DEMAND]
  > Second quarter 2026 total revenues were $2,155.8 million, up 3% from the second quarter of 2025. Shipments increased in aggregates (1%), and decreased in asphalt mix (12%) and ready-mixed concrete (17%). Gross profit increased in the Aggregates segment ($7.8 million or 1%), decreased in the Asphalt 
- **[PRINCIPLE] Building Materials And Aggregates Unit Economics** (NEGATIVE, Risk: HIGH): Aggregates freight-adjusted unit cost of sales increased 2% year over year, or 4% on a cash-cost basis, while the selling price increased 3.5%. Cash gross profit per ton improved 3% to $10.93. This indicates that pricing still exceeded cost growth in the earlier quarter, so the risk was easing versus the prior-year quarter. The later baseline shows unit cash cost rising 7%, including a 3% increase excluding diesel, so the risk subsequently intensified. (2 intensifying, 2 easing, 1 high-severity)
  > Aggregates freight-adjusted selling prices increased 3.9% compared to the prior year (4.7% on a mix-adjusted basis). Second quarter freight-adjusted unit cost of sales increased 7% (7%, or $0.72 per ton, on a unit cash cost of sales basis). Excluding the impact of higher diesel fuel costs, cash cost
- **[PRINCIPLE] Building Materials And Aggregates Regulatory Position** (NEGATIVE, Risk: HIGH): INTENSIFYING. Environmental liabilities and reclamation obligations increased versus the older comparison period. Accrued environmental remediation costs rose to $54.6 million from $41.6 million, while asset retirement obligations rose to $446.1 million from $346.5 million. The filing also states that California properties are being reclaimed for alternative uses and that costs were adjusted upward. These obligations can increase cash costs and may limit the use or expansion of reserves. (4 intensifying, 1 stable, 1 high-severity)
  > On May 5, 2022, Mexican government officials presented employees at our Calica operations in Quintana Roo, Mexico with arbitrary shutdown orders to immediately cease underwater quarrying and extraction operations. ... On September 23, 2024, the President of Mexico signed a presidential decree declar
- **[TREND] Building Materials And Aggregates Demand Cycle** (NEGATIVE, Risk: HIGH): EASING. In the older comparison period, demand was more disrupted by hurricanes and severe storms. In Q3 FY25, aggregates shipments increased 12% year over year and management cited healthy public construction activity. For the first nine months, shipments were up 3%, and management expected similar full-year shipment growth. The risk remains material because construction spending is cyclical and results are seasonal, but the latest operating evidence shows improved volumes. (3 easing, 1 stable, 1 intensifying, 1 high-severity)
  > Demand for our products is dependent on construction activity and correlates positively with changes in population, employment and household formations. ... Furthermore, our sales and earnings are sensitive to national, regional and local economic conditions, demographic and population fluctuations,
- **[TREND] Building Materials And Aggregates Digital and Automation Shift** (NEUTRAL, Risk: MODERATE): A new enterprise resource planning system and related reporting-system changes create execution and internal-control risk. Implementation problems could disrupt budgeting, forecasting, financial reporting, or daily operations even though management currently says disclosure controls are effective. [EXECUTION]
  > We are also executing a comprehensive modernization of our core business systems and processes, which will include the implementation of a cloud-based Enterprise Resource Planning (ERP) software suite ... The full implementation is expected to be completed by the third quarter of 2027.
- **[TREND] Building Materials And Aggregates Market Structure** (NEUTRAL, Risk: MODERATE): EASING. The older comparison period showed weaker profitability, particularly in concrete, including an $86.6 million goodwill impairment in Q3 FY24. In Q3 FY25, asphalt shipments increased 5%, concrete shipments increased 32%, asphalt gross profit rose 18% to $71.0 million, and concrete gross profit more than doubled to $14.1 million. The businesses remain lower-margin than aggregates, especially concrete, but current volumes and profits improved materially. (1 easing, 1 intensifying)
  > the highly competitive nature of the construction industry
- **[TREND] Building Materials And Aggregates Policy and Regulation** (NEGATIVE, Risk: HIGH): The risk intensified after year-end 2025. At December 31, 2025, management could not reasonably estimate a loss related to LADWP's potential contribution claim. In January 2026, LADWP presented a demand that included costs above its previously reported estimates, and management stated that a material loss could be recognized in the near term. The independent auditor identified the matter as a critical audit matter. (4 intensifying, 1 stable, 2 high-severity)
  > LADWP presented a demand to Vulcan in January 2026 that included actual costs in excess of these publicly-reported estimates. ... At this time, we cannot reasonably estimate a range of a loss pertaining to LADWP’s potential contribution claim. However, as discussions continue with LADWP and as addit
- **[TREND] Building Materials And Aggregates Supply Chain Reconfiguration** (NEUTRAL, Risk: MODERATE): STABLE. Management continued to identify labor constraints as a potential source of delays and inefficiency, but the filing provided no quantified deterioration. Despite the risk, Q3 shipments and margins improved, suggesting no broad current operating damage. The risk remains relevant but its severity was not clearly changed. (3 stable, 1 insufficient_data)
  > Inflationary pressures and labor constraints can be factors that impact our operations. ... Additionally, labor constraints can cause delays and inefficiencies in our operations as well as those of our customers.

### Scenario Analysis

- The first-order impact runs through mortgage rates, project financing, and equity discount rates: higher rates can delay housing and private nonresidential projects that consume Vulcan's aggregates, asphalt, and concrete, while its fixed-rate debt prevents a comparable immediate increase in interest expense. A rate-cut cycle would eventually improve housing affordability, construction starts, corporate capex, and the market value of long-lived quarry and plant assets, although the benefit would arrive with a lag. Second-order effects could include stronger shipments, better utilization, and cheaper financing for acquisitions, allowing Vulcan to continue consolidating attractive aggregates assets. Third-order, Vulcan's liquidity and low leverage could widen its advantage over weaker competitors facing refinancing pressure, while a lower discount rate could support the stock's valuation; conversely, persistent high rates and weak volumes could pressure asset values and multiples. (POSITIVE)
  > Economic pressures on our customers, including the challenges of inflation, heightened geopolitical tensions and the impact of tariffs and other trade measures, may negatively impact our shipment volumes. We will continue to evaluate the evolving macroeconomic environment to take action to mitigate 
- Tariffs have limited direct impact on Vulcan because aggregates, asphalt, and concrete are primarily supplied and sold domestically, but trade friction can weaken customers and disrupt the Canadian quarry route serving California and Hawaii. The more important first-order effect is increased US manufacturing, warehouse, utility, and infrastructure construction, which raises demand for Vulcan's materials. In the second order, Vulcan's internal aggregate supply, pricing actions, barges, rail, and marine distribution should improve resilience and allow it to serve markets where local supply is constrained, though diesel, liquid asphalt, labor, and freight costs can compress margins. Over time, the third-order result is a stronger strategic position for permitted domestic reserves and distribution assets, potentially shifting construction-material profit pools toward Vulcan, but the benefit is likely gradual and cyclical rather than a tariff-driven earnings step-change. (POSITIVE)
  > Additionally, we serve markets in California and Hawaii from our quarry in British Columbia, Canada by means of a long-term marine shipping agreement with CSL Americas.
- The first-order AI effect that applies is physical data-center and related infrastructure construction, which can increase demand for Vulcan's stone, sand, and gravel, although current filings attribute growth to public construction and large projects generally. At the second order, higher project activity could support volumes, pricing, capacity utilization, and the value of Vulcan's quarries, rail yard, barge, and distribution network, but diesel, freight, labor, and permitting costs could absorb part of the benefit. At the third order, local reserves, permits, and transportation density could become more valuable in constrained metropolitan markets, potentially improving market share and pricing power. However, Vulcan remains several steps downstream from AI spending and lacks disclosed hyperscaler contracts, data-center backlog, or measurable AI-linked revenue. (NEUTRAL)
  > Demand for our products is dependent on construction activity and correlates positively with changes in population, employment and household formations. End uses include public construction (e.g., highways, bridges, buildings, airports, schools, prisons, sewer and waste disposal systems, water suppl
