MUELLER WATER PRODUCTS REPORTS FISCAL THIRD QUARTER 2007 RESULTS

(ATLANTA) — Mueller Water Products, Inc. (NYSE: MWA.B, MWA) today reported net sales of $502.5 million, income from operations of $57.4 million, and a net loss of $1.3 million, or $0.01 per diluted share (earnings of $0.17 per diluted share, excluding loss on early extinguishment of debt) in the third quarter ended June 30, 2007. Summarized consolidated highlights of 2007 third quarter results, as compared to 2006 third quarter results, are as follows:

· Consolidated net sales for the third quarter were $502.5 million, up 0.5 percent compared to $500.0 million for the same period last year.

· Operating income for the quarter was $57.4 million compared to $69.4 million for the third quarter 2006. The prior year quarter included $3.4 million of plant closure and acquisition costs. Operating income margin was 11.4 percent in the third quarter 2007, down from 13.9 percent in the third quarter 2006.

· Adjusted EBITDA was $83.2 million in the third quarter 2007 compared to $97.4 million in the third quarter 2006.

· Loss per diluted share was $0.01 for the third quarter 2007 and earnings per diluted share for the same period last year were $0.41. Primary drivers of this difference were the comparative effect of income tax rates, losses on early extinguishment of debt and the increase in average diluted shares outstanding.

“We continue to take action in response to difficult market conditions and have been able to mitigate some of the impact of year-over-year volume declines,” said Chairman, President and CEO Gregory E. Hyland. “Over the past year, we aggressively reduced our fixed cost structure through plant closures and consolidations. During the quarter, we diligently managed controllable expenses and heightened our focus on increasing cash flows by reducing inventories. We also were successful in strengthening our capital structure by refinancing our debt, which lowers interest expense, increases operational flexibility and simplifies the Company’s debt structure. The actions we have taken enhance our ability to not only respond to the current business cycle, but to also benefit from the attractive long-term fundamentals of our market.”

Operating Results

Net sales increased primarily due to higher pricing across all segments, the acquisition of Fast Fabricators and increased volume in the Anvil segment. These benefits offset volume declines in water infrastructure products that were principally caused by the downturn in residential construction and strong pre-buying last year in advance of third quarter 2006 price increases in the Mueller Co. segment.

The decline in operating income and related margin was largely attributable to lower shipment volumes of higher-margin water infrastructure products. Reduced production throughput and increased raw material costs in the Mueller Co. and U.S. Pipe segments also impacted profitability. These results were partially offset by higher pricing and the elimination of certain fixed costs due to 2006 plant closures.

Adjusted EBITDA margin (see discussion of non-GAAP measures below) for the quarter ended June 30, 2007 was 16.5 percent compared to 19.4 percent in the same period last year. This margin contraction occurred as a result of the decline in operating income. Adjusted EBITDA in third quarter 2006 excluded $3.4 million of certain plant closure and acquisition costs.

Segment Results

Mueller Co. Segment
Net sales for the Mueller Co. segment were $208.1 million in the third quarter of 2007 compared to $225.5 million in the third quarter of 2006. Volume declines were partially offset by price increases implemented since May 2006. Reduced volumes in iron gate valves, hydrants and brass service products were the result of continuing weakness in residential construction and strong shipments in the third quarter of 2006. Pre-buy orders that preceded price increases instituted in May and June of 2006 benefited the level of shipments in the third quarter of 2006.

Income from operations of $41.5 million and Adjusted EBITDA of $54.7 million in the third quarter of 2007 compares to income from operations of $56.8 million and Adjusted EBITDA of $70.0 million in the third quarter of 2006. The declines principally resulted from reduced shipments of the higher-margin iron gate valve and hydrant product lines. Lower year-over-year production volumes also drove margin compression. Higher pricing covered the increase in raw material costs.

U.S. Pipe Segment
Net sales for the U.S. Pipe segment were $154.5 million in the third quarter of 2007 compared to $143.8 million in the prior year quarter. Price increases and results from the Fast Fabricators acquisition more than offset the impact of lower ductile iron pipe shipments. While volume related to repair and replacement work in the municipal sector increased year-over-year, it did not offset weakness in residential construction.

Income from operations of $8.9 million and Adjusted EBITDA of $15.2 million in the third quarter of 2007 compares to income from operations of $7.6 million and Adjusted EBITDA of $16.2 million in the third quarter of 2006. Income from operations in the prior year quarter includes $3.2 million of costs related to the closure of the Chattanooga, Tenn., valve and hydrant plant, as well as $2.0 million of related party charges allocated to U.S. Pipe by the Company’s former parent. Income from operations and Adjusted EBITDA performance were negatively impacted by lower volumes and higher scrap iron raw material costs.

Anvil Segment
Net sales for the Anvil segment of $146.2 million in the third quarter of 2007 increased 7.1 percent compared to $136.5 million in the third quarter of 2006. Net sales increased due to both higher prices and volume growth primarily from commercial construction demand.

Income from operations of $17.4 million and Adjusted EBITDA of $23.2 million in the third quarter of 2007 compares to income from operations of $12.2 million and Adjusted EBITDA of $18.4 million in the third quarter of 2006. Third quarter 2007 operating income margin of 11.9 percent and Adjusted EBITDA margin of 15.9 percent increased from 8.9 percent and 13.5 percent, respectively, in the third quarter of 2006. These improved results benefited from higher prices, volume growth and an additional $1.2 million of dumping duties from the federal government.

Interest Expense and Debt Extinguishment

Interest expense, net, of $23.3 million in the third quarter of 2007 declined from $27.8 million in the third quarter of 2006 as a result of lower average debt levels. In the third quarter of 2007, interest expense included a $1.7 million charge related to an interest rate swap adjustment.

The Company recorded a loss on the extinguishment of debt of $36.4 million and $4.1 million in the third quarters of 2007 and 2006, respectively. In May 2007, the Company issued $425 million of 7⅜ percent senior subordinated notes and used the proceeds primarily to repurchase the remaining outstanding senior subordinated and senior discount notes. In June 2006, the Company issued equity in its initial public offering and subsequently used the net proceeds to partially redeem outstanding debt.

Shares Outstanding

Weighted average diluted shares outstanding of 115.3 million in the third quarter of 2007 increased from 95.3 million in the third quarter of 2006 due primarily to the June 2006 initial public offering of 28.8 million shares of Series A common stock.

Use of Non-GAAP Measures

Adjusted EBITDA represents income before depreciation, amortization, interest expense, interest income, income taxes, acquisition related adjustments such as the cost of the closure of the U.S. Pipe Chattanooga facility and adjustments made as a result of the acquisition to increase the manufactured cost of acquired inventory to fair value. The Company presents Adjusted EBITDA because we consider it an important supplemental measure of performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the industry, substantially all of which present Adjusted EBITDA when reporting their results.

In addition, the credit agreement uses EBITDA (with additional adjustments) to measure compliance with covenants, such as interest coverage and leverage ratios.

A form of EBITDA also is widely used by the Company and others in its industry to evaluate and price potential acquisition candidates.

Adjusted EBITDA has limitations as an analytical tool, and investors should not consider it in isolation or as a substitute for analysis of the Company’s results as reported under GAAP. Some of these limitations are:

Adjusted EBITDA does not reflect the Company’s cash expenditures or future requirements for capital expenditures or contractual commitments. Adjusted EBITDA does not reflect changes in, or cash requirements for, working capital needs.

Adjusted EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments on debt. Although depreciation and

amortization are non-cash charges, the assets being depreciated and amortized often will have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements; and other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Adjusted EBITDA is a measure of performance that is not required by, or presented in accordance with, GAAP. Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measure derived in accordance with GAAP.
