Negatives

• Decreased demand from oil and gas services customers in 2025.
• Anticipated continued weakness in demand from roof shingle customers in early 2026.
• A major winter storm in January 2026 interrupted product shipments, with an undetermined impact on first quarter 2026 financial performance.
• Selling, general and administrative (SG&A) expenses increased 28.8% in 2025, rising to 6.5% of revenues from 5.9% in 2024, primarily due to increased personnel expenses.
• Total limestone mineral reserves decreased from 226,900 thousand tons in 2024 to 223,150 thousand tons in 2025.

Risks

• Uncertain economic and regulatory conditions in the United States and specific industries could lead to reduced demand for lime and limestone products.
• Decreased demand from utility customers due to the trend towards reducing reliance on coal-fired utility plants.
• Operating risks beyond control, such as geological formation problems, accidents, equipment failures, strikes, and adverse weather conditions, could disrupt operations, increase costs, and decrease production.
• The highly regionalized and competitive lime and limestone industry could lead to increased competitive pressures, including pricing pressure and difficulty retaining customer accounts.
• Increased energy, labor, and parts and supplies costs, which may not be fully passed on to customers, could adversely affect profitability.
• Potential for major rail disruptions affecting the availability of solid fuels (coal and petroleum coke) for plants.
• High and generally increasing freight costs, particularly due to diesel prices, could reduce profitability, especially for delivered price quotes.
• Uncertainty in the ability to sell any increased production capacity from modernization and expansion projects at acceptable prices.
• Limited ability to insure against certain mining and production risks, with potential for liabilities to exceed policy limits.
• Disruption in, or failure of, information technology systems, including due to cybersecurity risks and incidents, could adversely impact operations, sales, or financial functions.
• Pandemics, epidemics, or disease outbreaks could materially adversely impact financial condition, results of operations, cash flows, and competitive position.
• Changes in the governmental, legal, and regulatory environment (e.g., zoning, mine permitting, mine safety, reclamation, environmental laws) could increase compliance costs and adversely impact operations.
• Uncertainty and rapid changes in Environmental Laws and their enforcement, including greenhouse gas regulations, could lead to significant costs, difficulties in obtaining permits, or operational limitations.
• Mine safety regulations under the Federal Mine Safety and Health Act of 1977 (Mine Act) can result in citations, orders, and penalties based on strict liability.
• Accrued Asset Retirement Obligations (AROs) may not be sufficient to meet all future reclamation and remediation obligations.

Future Outlook

The new vertical kiln at the Texas Lime plant is expected to start up in the summer of 2026, with most of the remaining $65 million project costs anticipated in 2026. The company expects strong continued demand from construction customers, particularly in Texas, due to infrastructure investment and population growth. However, weakness in demand from roof shingle customers is expected to continue in early 2026, and the impact of the January 2026 winter storm on Q1 2026 financial performance is yet to be determined. The company anticipates funding operating and capital needs and regular cash dividends from cash on hand and cash flows from operations, absent a significant acquisition.

Management Comments

• We believe that our modernization, expansion, and development projects in Texas, Arkansas, and Oklahoma, our acquisitions in Oklahoma and Missouri, and our lime slurry operations in Texas, should allow us to continue to remain competitive, protect our markets and position ourselves for the future.
• We will continue to evaluate internal and external opportunities for expansion, growth, and increased profitability as conditions warrant or opportunities arise.
• We believe that it is responsible to its employees to provide a safe and healthy workplace environment.
• We intend to comply with all Environmental Laws and believe our accrual for environmental costs and liabilities at December 31, 2025 is reasonable.
• We intend to comply with all mining regulations and all of our reclamation and remediation obligations.
• Absent a significant acquisition, we believe that cash on hand and cash flows from operations will be sufficient to meet our operating needs, ongoing capital needs, including our current and possible future modernization and expansion and development projects, such as the Texas kiln project, and liquidity needs and allow us to pay our regular cash dividends for the short-term and beyond.

Industry Context

StockSavvy.ai notes that the lime industry is highly regionalized and competitive, characterized by high barriers to entry including scarcity of high-quality deposits, proximity to markets, and stringent environmental regulations. The company's strong performance in 2025, driven by construction and environmental demand, contrasts with reduced demand from the oil and gas services sector, reflecting broader cyclical trends. The long-term shift away from coal-fired utility plants continues to reduce demand for lime in flue gas treatment, increasing competitive pressures. The company's strategic investments in modernization and expansion, like the Texas kiln project, are crucial for maintaining competitiveness against larger, consolidating industry players and adapting to evolving market demands.

Comparison to Industry Standards

• The company's 5-year cumulative total stockholder return (536.00%) significantly outperformed the NASDAQ Composite Index (187.14%) and its 2025 Peer Group Index (215.83%) as of December 31, 2025.
• The 2025 Peer Group includes Eagle Materials, Inc., Mineral Technologies, Inc., Arcosa Inc., and Granite Construction Inc.
• The company's utilization rate of approximately 80% of total annual production capacity for lime and limestone during 2025 indicates efficient operations relative to its infrastructure.
