Exhibit 19.1 To Our Stockholders, Customers, and Employees Mueller's net income in the first quarter of 2008 increased forty-five percent to $27.4 million, or 73 cents per diluted share. This compares with $18.9 million, or 51 cents per diluted share, for the same period of 2007. First quarter net sales for 2008 were $704.1 million compared with $609.8 million in 2007. The increase in net sales was primarily attributable to acquired businesses. The change in net sales was also affected by the increased cost of copper, the Company's principal raw material, which was largely passed through to customers, offset by lower unit volume. The COMEX average price of copper was $3.53 per pound in the first quarter of 2008, which compares with $2.70 in the first quarter of 2007. Our Plumbing & Refrigeration segment posted operating earnings of $25.1 million on net sales of $383.9 million, which compares with prior year earnings of $26.9 million on net sales of $370.0 million. Operating results were affected by lower unit volumes and spreads in copper tube and DWV plastic fittings. Other key product lines performed well. Our OEM segment posted operating earnings of $25.6 million during the first quarter of 2008 on net sales of $326.2 million, which compares with operating earnings of $5.5 million on net sales of $243.7 million for the same period in 2007. The acquisition of Extruded Metals, a brass rod mill, at the end of February 2007, was an important contributor to the improvement in our operating income during the quarter. We believe there are additional opportunities to rationalize production as we integrate our brass rod mill operations. The housing construction market continues to contract. Housing starts have already declined almost 60 percent over the past 2 1/2 years. However, we believe the market is close to a bottom, and that it will soon commence a gradual, but perhaps fitful, improvement. Mortgage rates remain at historically low levels and will provide an incentive for buyers to return to the housing market. On the other hand, the private non-residential construction market, an important market for Mueller, continues to show strength. So far this year it has grown at an annualized rate of 13 percent. Economists are divided over whether our nation has entered into a recession. If, in fact, we are in a recession, our goal is to emerge from the downturn, a stronger and more formidable competitor.
