Key Financial Metrics

Margins (GAAP): Gross margin was 20.3% (vs. 17.5% in 2006); Operating margin was 12.5% (vs. 10.7% in 2006).

Material Changes vs. Prior Period

• Revenue and Volume: Net sales decreased 2.1% to $414.5 million. Heritage aggregates volume decreased 14.6% due to severe winter weather (particularly in the West Group and Indiana/Ohio) and a significant decline in residential construction demand. However, heritage pricing increased 15.4%, driven by favorable product and geographic mix.
• Profitability: Despite lower volume, Net Earnings increased 6.4% to $33.0 million. Earnings from operations rose 12.0% to $57.8 million. Gross margin expanded by 310 basis points for the heritage aggregates product line.
• Cost Management: Quarry-level production costs decreased. Total paid man-hours declined nearly 15%, while productivity (tons per paid man-hour) increased 3.5%.
• Debt Structure: Total debt increased significantly due to the issuance of $248 million in commercial paper to fund operations and stock repurchases. Long-term debt remained relatively stable, though current maturities increased.
• Shareholder Returns: The Company repurchased 2,335,000 shares of common stock for $302.0 million (average cost $129.33/share). Cash dividends per share increased to $0.275 from $0.23.
• Tax Rate: The effective income tax rate for continuing operations increased to 33.8% from 31.7%, primarily due to the adoption of FIN 48 (Accounting for Uncertainty in Income Taxes) and discrete tax impacts from stock option exercises.

Guidance, Outlook, and Risks

Management Commentary and Outlook

• 2007 Full-Year Guidance: Management raised net earnings guidance to a range of $6.10 to $6.65 per diluted share (previously lower). This includes the impact of FIN 48.
• Q2 2007 Guidance: Expected net earnings of $1.85 to $2.10 per diluted share.
• Aggregates Outlook: Pricing is expected to increase 10% to 11.5% for the year due to supply constraints and rising replacement costs. Demand is expected to be flat to down 2% for the full year, with a softer first half mitigated by volume growth in the second half. Commercial and infrastructure construction are expected to increase, though residential construction is expected to decline significantly in the first half.
• Specialty Products: Expected to contribute $33 million to $36 million in pretax earnings for 2007, up from $22 million in 2006.

Risks and Contingencies

• Weather and Seasonality: Operations are highly seasonal and sensitive to weather conditions (e.g., severe winter weather, hurricanes, excessive rainfall).
• Construction Market: Results depend on federal and state transportation funding levels and the health of the residential and commercial construction markets.
• Input Costs: Significant exposure to energy costs (diesel, natural gas, liquid asphalt). A 10% increase in energy prices could impact pretax earnings by approximately $17.8 million.
• Interest Rates: Exposure to variable interest rates on commercial paper ($248 million outstanding). A 100 basis point increase would increase annual interest expense by $2.5 million.
• Tax Uncertainty: Adoption of FIN 48 created uncertainty regarding unrecognized tax benefits, with a reasonably possible change of $8.3 million to $27.8 million in the next 12 months due to IRS audits and statute of limitations expirations.

Subsequent Events

• Debt Refinancing: On April 25, 2007, the Company issued $475 million in Senior Notes ($250 million 6.25% due 2037 and $225 million Floating Rate due 2010) to repay commercial paper and fund the repayment of $125 million in notes due in August 2007.
• Credit Agreement: On April 17, 2007, the Company amended its revolving credit agreement, modifying the leverage ratio covenant to not exceed 2.75 to 1.00.

Investor Verification Checklist

• Debt Maturity Wall: Verify the successful repayment of the $125 million 6.9% Notes due in August 2007 using proceeds from the April 2007 Senior Notes issuance.
• FIN 48 Impact: Monitor the resolution of IRS audits for 2004 and 2005 tax years and the expiration of the 2003 statute of limitations, which could materially affect tax liabilities and earnings.
• Residential Construction Trends: Track the severity and duration of the decline in residential construction, which management expects to moderate in the latter half of 2007.
• Energy Cost Volatility: Monitor diesel and natural gas prices, as a 10% fluctuation has a material impact ($17.8 million) on pretax earnings.
• Stock Repurchase Authorization: Confirm remaining authorization levels (1,896,000 shares remaining as of March 31, 2007) and future buyback activity.
