TO OUR STOCKHOLDERS, CUSTOMERS AND EMPLOYEES The third quarter of 1997 was the best quarter in Mueller's history. Operating income, net earnings, and pounds of product manufactured and shipped all reached record levels. Net earnings for the third quarter of 1997 were $18.1 million, or 92 cents per share, compared to $16.2 million, or 83 cents per share, for the third quarter of 1996. This earnings record was achieved even though our recently acquired European copper tube businesses incurred operating losses of approximately $2 million. We acquired these businesses for a modest investment, with the objective of improving their cost structure and productivity. We see great opportunity to build substantial values in Europe. Net sales for the third quarter of 1997 totaled $229.1 million, an increase of 30 percent over sales of $176.0 million for the same quarter of 1996. Pounds shipped increased by 24 percent. Volume in the U.S. copper tube business continues to be strong; spreads have improved from the second quarter of 1997, though they remain significantly below levels achieved in the third quarter of 1996. Earnings at our copper fittings operations were the best ever. Brass rod also operated with solid volume and earnings. Our DWV plastics business continues to grow. We recently purchased a factory building, which is contiguous to our existing plant in Kalamazoo, Michigan. Nineteen additional injection molding presses were installed in this expansion, and in other facilities. Our copper refinery project in Fulton, Mississippi is on schedule. This $25 million investment, when completed in 1999, will allow our Fulton tube mill to use a lower cost mix of scrap and cathode. Financing was established for this project through a Mississippi Industrial Revenue Bond, which will generate ongoing tax benefits. U.S. economic conditions remain favorable for our business. Fixed 30- year mortgage rates are near 7.5 percent. Unemployment is close to its lowest level in more than 25 years. Inflation is modest. Consumer confidence is high. Although new housing starts declined slightly during the third quarter, the housing market remains solid. Consequently, we are optimistic that Mueller's business will be sound through the end of the year, and into 1998. Sincerely, /s/ Harvey L. Karp Harvey L. Karp Chairman of the Board /s/ William D. O'Hagan William D. O'Hagan President and Chief Executive Officer October 14, 1997 Corporate News Plastics Business Continues Consistent Improvement Profits at Mueller's DWV plastic fittings business have improved dramatically since 1996. The plastic fittings unit earned the prestigious Harvey L. Karp EBIT ("Everyone Benefits In Teamwork") Award in five consecutive quarters commencing with the second quarter of 1996. This deserves special recognition because we have never had back-to-back winners before. This internal award recognizes the business which demonstrates the best earnings improvement over the preceding quarter. The award was established in 1993, and has encouraged a healthy rivalry among the Company's operating units. -2-
