Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 10.2% to $3.77 billion, driven primarily by the acquisition of Nehring Electrical Works Company ($220.7 million in sales) and Elkhart Products Corporation ($26.2 million in sales), alongside higher net selling prices in core product lines.
• Segment Performance:
  • Industrial Metals: Sales surged 41.6% and operating income rose 21.2%, largely due to the Nehring acquisition.
  • Piping Systems: Sales grew 5.5% and operating income increased 8.5%, supported by higher prices and the Elkhart acquisition, offset by lower unit volumes.
  • Climate: Sales declined 2.5% and operating income dropped 15.0% due to reduced demand in residential construction and lower volumes/prices in certain product lines.
• Margin Compression: Consolidated gross margin decreased to 27.7% from 28.9%, attributed to higher raw material costs and mix shifts, despite price increases passed to customers.
• One-Time Items: 2023 included a $19.5 million gain from an insurance settlement (Bluffs, IL fire) and a $4.1 million gain on the sale of Heatlink Group. 2024 included a $5.8 million gain on the sale of assets and a $1.3 million gain on the extinguishment of a New Markets Tax Credit liability.

Guidance, Outlook, and Risks

• Capital Expenditures: Management anticipates investing approximately $70.0 million to $80.0 million in capital expenditures for 2025.
• Dividends: The quarterly cash dividend was $0.20 per share in 2024 (up from $0.15 in 2023). Future payments depend on financial condition and cash flows.
• Share Repurchases: The Board extended the authorization to repurchase up to 40 million shares through July 2026. Approximately 15.9 million shares have been repurchased since 1999.
• Key Risks:
  • Raw Material Volatility: Significant exposure to copper, brass, and energy price fluctuations. The company attempts to pass costs through but may face delays or competitive pressure.
  • Tariffs: New tariff increases on imports from Canada, Mexico, and China announced in February 2025 could adversely impact gross margins if sustained.
  • Construction Sensitivity: Demand is tied to housing starts and commercial construction, which are sensitive to interest rates and economic conditions.
  • Environmental Liabilities: Ongoing remediation obligations with a reserve of $18.4 million; future costs may exceed estimates.

Investor Verification Checklist

• Acquisition Integration: Verify the performance and integration progress of Nehring Electrical Works (acquired May 2024) and Elkhart Products (acquired August 2024), which drove significant revenue growth.
• Margin Sustainability: Monitor the ability to pass through raw material cost increases to customers without losing market share, given the decline in gross margin percentage.
• Tariff Impact: Assess the potential financial impact of the February 2025 tariff announcements on Canadian, Mexican, and Chinese imports on future operating margins.
• Climate Segment Demand: Track recovery in the Climate segment, which faced a 15% drop in operating income due to weak residential construction demand.
• Environmental Reserves: Review the adequacy of the $18.4 million environmental reserve against ongoing remediation projects, particularly at the Shasta Area Mine Sites and Lead Refinery Site.
