Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Q3 2025 net sales increased 8.0% year-over-year, driven primarily by higher net selling prices ($98.6 million) due to rising raw material costs, partially offset by lower unit volumes ($43.3 million). YTD sales grew 13.0%, significantly boosted by the Nehring acquisition ($197.1 million) and Elkhart acquisition ($35.1 million).
• Profitability: Operating income rose 33.6% in Q3 and 31.1% YTD. Gross margins improved to 31.5% in Q3 (from 27.6% in Q3 2024) and 30.0% YTD (from 27.7%).
• Unusual Items:
  • Insurance Gains: Recognized a $4.9 million pre-tax gain in Q3 and $41.1 million YTD related to excess insurance proceeds from the March 2023 tornado at the Covington, Tennessee facility.
  • Asset Disposal: Recorded net gains on asset disposals of $11.9 million in Q3 and $26.7 million YTD.
  • Impairments: Incurred $2.0 million in asset impairment charges on idled equipment in both Q3 and YTD.
  • Pension Withdrawal: Recognized a $4.8 million expense related to the withdrawal from a multiemployer pension plan (IAM Plan) following the Elkhart acquisition.
• Acquisitions: The Nehring acquisition (closed May 2024) contributed significantly to Industrial Metals sales. The Elkhart acquisition (closed August 2024) contributed to Piping Systems sales.

Guidance, Outlook, and Risks

• Liquidity: The company maintains a strong liquidity position with $1.26 billion in cash and $371.8 million available under a $400 million revolving credit facility (maturing March 2026). There is no outstanding debt.
• Capital Allocation: The company repurchased $243.6 million of common stock YTD 2025. The Board has authorized repurchases of up to 40 million shares through July 2026. Dividends were declared at $0.25 per share for each of the first three quarters of 2025.
• Market Risks:
  • Commodity Prices: Earnings depend on "spreads" between raw material costs (copper, brass) and selling prices. The company uses futures contracts to hedge exposure.
  • Construction Demand: Sales are tied to new housing starts and commercial construction. August 2025 housing starts were 1.31 million, down from 1.36 million in September 2024.
  • Environmental Liabilities: Significant ongoing remediation obligations exist for non-operating properties (e.g., Kansas smelter sites, Shasta mines, Lead Refinery site). The company estimates spending $3.5 million over the next 12 months for environmental activities.
• Outlook: Management anticipates the annual effective tax rate will be consistent with the first nine months (25%). No specific forward-looking revenue or earnings guidance was provided in this filing.

Investor Verification Checklist

• Insurance Proceeds: Verify the final settlement amount for the Covington tornado claim, as the claim is not yet fully settled and future gains are expected.
• Acquisition Integration: Monitor the integration progress and performance of the Nehring and Elkhart acquisitions, which drove significant YTD revenue growth.
• Commodity Spreads: Track copper and brass price fluctuations and the company's ability to pass costs to customers to maintain gross margins.
• Environmental Reserves: Review updates on the Lead Refinery NPL site and Kansas smelter sites, as potential liabilities could exceed current reserves.
• Share Repurchases: Confirm the pace of share buybacks under the $40 million share authorization extended to July 2026.
