“As we discussed last quarter, municipal budgets continue to be under significant pressure which is impacting demand for our products,” said Gregory E. Hyland, chairman, president and chief executive officer of Mueller Water Products. “Lower production levels in our Mueller Co. business negatively affected our 2011 fourth-quarter performance as compared to 2010. Production at Mueller Co. was down appreciably this year compared to last year largely due to the pull forward of orders in advance of our July 2010 price increases.

“The process of evaluating strategic alternatives for our U.S. Pipe business is moving forward as planned, and we continue to make progress on transactional scenarios that could result in the disposition of the business. We remain actively engaged in this process with our financial advisor, BofA Merrill Lynch.

“Anvil had another strong quarter with net sales increasing 8.2 percent and adjusted operating income increasing 38 percent in the fourth quarter on a year-over-year basis. Anvil’s results continue to be driven by both ongoing volume growth, notably in its oil & gas business, and productivity improvements.

“We have been able to manage through unprecedented volume declines with our Mueller Co. and U.S. Pipe businesses and have improved the efficiency of all our operations. We believe we are well positioned with our market leadership and we continue to invest in newer technologies, which leverage our brand leadership and address the evolving needs of the water infrastructure industry. We continue to move our businesses in directions that we believe will allow us to grow as municipalities emerge from their current budget restraints.”

Fourth Quarter Consolidated Results

Net sales for the fourth quarter were $373.6 million compared to net sales for the 2010 fourth quarter of $346.7 million. Net sales increased due to higher shipment volumes of $12.6 million, primarily at U.S. Pipe, higher prices of $12.6 million across all three businesses and $1.7 million of favorable Canadian currency exchange rates.

Adjusted income from operations for the 2011 fourth quarter was $9.1 million compared to adjusted income from operations for the 2010 fourth quarter of $15.4 million. Higher per-unit overhead costs due to lower production of $15.3 million primarily at Mueller Co., higher raw material costs of $11.0 million and higher selling, general and administrative expenses of $1.1 million were partially offset by higher sales prices of $12.6 million and manufacturing and other cost savings of $10.7 million.

Interest Expense, Net

Income Taxes

The 2011 fourth quarter income tax benefit of $1.7 million, an effective tax rate of 18 percent, reflected an income tax benefit on current operations partially offset by an adjustment to the expected effective tax rates for state and non-U.S. income taxes.

Use of Non-GAAP Measures

The Company presents adjusted income (loss) from operations, adjusted operating margin, adjusted EBITDA, adjusted EBITDA margin, adjusted net income (loss), adjusted net income (loss) per share, free cash flow and net debt as non-GAAP measures. Adjusted income (loss) from operations represents income (loss) from operations excluding restructuring. This amount divided by net sales is adjusted operating margin. Adjusted EBITDA represents income (loss) from operations excluding restructuring, depreciation and amortization. This amount divided by net sales is adjusted EBITDA margin. The Company presents adjusted income (loss) from operations, adjusted operating margin, adjusted EBITDA and adjusted EBITDA margin because these are measures management believes are frequently used by securities analysts, investors and interested parties in the evaluation of financial performance. Adjusted net income (loss) and adjusted net income (loss) per share exclude restructuring, certain costs from settled interest rate swap contracts, the income tax effects of these excluded items and a tax adjustment for the repatriation of earnings. These items are excluded because they are not considered indicative of recurring operations. Free cash flow represents cash flow from operating activities less capital expenditures. It is presented as a measurement of cash flow because it is commonly used by the investment community. Net debt represents total debt less cash and cash equivalents. Net debt is commonly used by the investment community as a measure of indebtedness. These non-GAAP measures have limitations as analytical tools, and securities analysts, investors and interested parties should not consider any of these non-GAAP measures in isolation or as a substitute for analysis of the Company's results as reported under accounting principles generally accepted in the United States ("GAAP").

A reconciliation of non-GAAP to GAAP results is included as an attachment to this press release and has been posted online at www.muellerwaterproducts.com.
