Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 10.9% to $4.18 billion, driven by higher net selling prices ($336.9M), acquisitions of Nehring ($208.1M) and Elkhart ($35.1M), and non-core product growth. This was partially offset by a $212.0M decrease in unit sales volume in core product lines.
• Profitability: Operating income rose 24.4% to $958.5 million. Net income increased 26.5% to $765.2 million. Gross margin expanded to 29.0% from 27.7%.
• Acquisitions: The Industrial Metals segment saw significant growth due to the full-year impact of the Nehring Electrical Works acquisition (closed May 2024). The Piping Systems segment benefited from the Elkhart Products Corporation acquisition (closed August 2024).
• Unusual Items:
  • Insurance Gains: Recognized a $41.1 million pre-tax gain on insurance proceeds related to the March 2023 tornado at the Covington, Tennessee facility.
  • Investment Gains: Recognized $18.5 million in realized and unrealized gains on short-term investments.
  • Impairment: Recorded $3.7 million in fixed asset impairment charges on idled equipment.
  • Pension Withdrawal: Incurred a $4.8 million expense related to the withdrawal from a multiemployer pension plan.

Guidance, Outlook, and Risks

• Capital Expenditures: Anticipated to be between $80.0 million and $90.0 million for 2026.
• Dividends: Paid $1.00 per share in 2025 ($0.25 quarterly). Future payments depend on financial condition and cash flows.
• Share Repurchases: The Board has authorized the repurchase of up to 40 million shares through July 2026. Approximately 19.0 million shares have been repurchased since 1999; 21.0 million shares remain available under the current authorization.
• Debt: The Company had no debt outstanding as of December 27, 2025. The $400 million revolving credit facility matures on March 31, 2026, and is currently being renegotiated.
• Key Risks:
  • Raw Material Costs: Volatility in copper, brass, and energy prices impacts margins. The Company attempts to pass costs through to customers but faces potential delays.
  • Trade Policy: Uncertainty regarding U.S. tariffs and trade barriers (e.g., with China, Mexico, Canada) could impact demand and costs.
  • Construction Cyclicality: Sales are sensitive to housing starts and commercial construction activity, which are influenced by interest rates and economic conditions.
  • Environmental Liabilities: Ongoing remediation obligations at non-operating properties (e.g., Kansas smelter sites, Lead Refinery site) with a reserve of $18.9 million.

Investor Verification Checklist

• Acquisition Integration: Verify the performance of the Nehring and Elkhart acquisitions against pro forma expectations and integration costs.
• Insurance Proceeds: Confirm the final settlement status of the Covington, Tennessee tornado claim and any remaining contingent liabilities.
• Debt Refinancing: Monitor the terms of the new credit agreement replacing the facility maturing in March 2026.
• Raw Material Spreads: Track the "spread" between raw material costs and selling prices, particularly for copper tube and brass rod, as this drives profitability.
• Environmental Reserves: Review updates on the Lead Refinery NPL site and Kansas smelter sites for potential increases in remediation costs beyond current reserves.
• Union Contracts: Monitor upcoming union contract expirations (e.g., Port Huron, Michigan in May 2026) for potential labor cost increases or work stoppages.
