WATTS WATER TECHNOLOGIES REPORTS THIRD QUARTER 2009 RESULTS

North Andover, MA...October 27, 2009.  Watts Water Technologies, Inc. (NYSE: WTS) today announced results for the third quarter ended September 27, 2009.  Sales for the third quarter of 2009 were $303.8 million, a decrease of $68.2 million, or 18%, compared to the third quarter of 2008. Net income for the third quarter of 2009 was $3.4 million, or $0.09 per share, compared to net income of $16.7 million, or $0.45 per share, for the third quarter of 2008. The results for the third quarter of 2009 include a loss from discontinued operations of $8.2 million, or ($0.22) per share, of which $7.3 million is from the estimated loss on disposal of Watts Valve (Changsha) Co., Ltd. (“CWV”), as previously announced.  Quarterly and year-to-date results for 2009 and 2008 have been restated to include CWV’s operating results in discontinued operations. Income from continuing operations attributable to Watts Water Technologies, Inc. for the third quarter of 2009 decreased by $4.7 million, or 29%, to $11.6 million, or $0.31 per share, compared to income from continuing operations for the third quarter of 2008 of $16.3 million, or $0.44 per share.

Sales for the first nine months of 2009 were $902.7 million, a decrease of $187.1 million, or 17%, compared to the first nine months of 2008. Net income for the first nine months of 2009 was $3.2 million, or $0.09 per share, compared to net income of $50.2 million, or $1.36 per share, for the first nine months of 2008.  Income from continuing operations attributable to Watts Water Technologies, Inc. for the first nine months of 2009 decreased by $18.0 million, or 37%, to $30.9 million, or $0.83 per share, compared to income from continuing operations for the comparable period of 2008 of $48.9 million, or $1.32 per share.

Results for the third quarter of 2009 include a net after-tax charge of $5.8 million, or $0.16 per share, mostly for asset write-downs and other costs incurred as part of our previously announced footprint reduction and restructuring programs, as compared to an after-tax charge of $0.6 million, or $0.02 per share, for the third quarter of 2008.  Included in 2009 restructuring and other charges is a $1.1 million gain from the disposition of Tianjin Tanggu Watts Valve Co. Ltd (“TWT”), a subsidiary the Company sold in October 2008.  The gain was deferred until all legal and regulatory matters in China were resolved.

Patrick S. O’Keefe, Chief Executive Officer, commented, “Cash generation continues to be a key objective, and the entire organization has delivered positive results. September year-to-date net cash provided by continuing operating activities was approximately $147.8 million, as compared to $90.4 million for the same period in 2008.  We achieved this increase primarily from better working capital management and cost containment.  As of September 27, 2009, we had $233.3 million of cash on our balance sheet.  Year-to-date free cash flow through September was $132.5 million as compared to $70.2 million for the same period in 2008.  Our net debt to capitalization ratio (defined as total debt less cash divided by total debt less cash plus equity) at the end of September was 12.2% as compared to 22.8% at December 31, 2008.” (Free cash flow and net debt to capitalization ratio are non-GAAP financial measures. Reconciliations of these non-GAAP financial measures to the nearest comparable GAAP measures are provided in Tables 1 and 2 of this press release.)

Commenting on sales for the third quarter, Mr. O’ Keefe noted, “Our top line continued to be challenged by the global recession.  The $68.2 million decrease in consolidated sales includes a decrease in organic sales of $61.1 million, or 16%, and unfavorable changes in foreign exchange rates of $5.1 million, or 1%.  Also, sales in the third quarter of 2008 included $2.0 million attributable to TWT.

“Sales in our North American segment decreased in the third quarter of 2009 by $35.9 million, or 16%, to $182.6 million compared to $218.5 million for third quarter of 2008.  This decrease was primarily due to a decline in organic sales of $34.8 million, or 16%, and, to a lesser extent, from unfavorable foreign exchange associated with the weakening of the Canadian dollar versus the US dollar.

“Organic sales in our North American wholesale market for the third quarter of 2009 were 21% lower as compared to the third quarter of 2008, primarily driven by volume reductions for sales into the commercial marketplace.  Organic sales in the North American home improvement retail market increased 7% for the third quarter of 2009 as compared to the third quarter of 2008.  This increase was primarily due to increased product volume from new product introductions and market share gains.

“We derived 38% of our total sales for the third quarter of 2009 from our European segment. European sales decreased $28.2 million, or 20%, to $116.4 million, as compared to $144.6 million for the third quarter of 2008.  This decrease was primarily due to a decline in organic sales of $24.2 million, or 17%, and from an unfavorable foreign exchange movement associated with the weakening of the euro versus the US dollar of $4.0 million, or 3%.  Most major channels and regions experienced market declines, including wholesale, OEM and the drainage markets.  Sales into Eastern Europe remained weak.

“China’s segment sales in the third quarter of 2009 decreased $4.1 million, or 46%, to $4.8 million compared to $8.9 million for the third quarter of 2008. This decrease was primarily due to a reduction in organic sales of $2.1 million, or 24%.  As mentioned previously, sales in the third quarter of 2008 included $2.0 million attributable to TWT.  The organic sales decline was due to weaker export sales to Europe.

Mr. O’Keefe concluded, “Our operating income for the third quarter of 2009 decreased by $5.9 million, or 20%, to $24.3 million as compared to $30.2 million in the third quarter of 2008. The main drivers of the reduction were incremental restructuring costs of $5.5 million, or 18%, and unfavorable foreign currency movements of $0.5 million, or 2%.  An organic decline of $1.3 million was primarily due to reduced revenues in the commercial market and increased fixed overhead as a percent of sales.  Restructuring costs decreased operating margins in the third quarter of 2009 and the third quarter of 2008 by 210 basis points and 20 basis points, respectively. Our operating margins were positively affected by increased gross margins from lower current quarter commodity costs and, in 2008, we had one-time acquisition charges which reduced gross margins.  Operating margins also benefited from lower selling, general and administrative expenses, which organically declined 11% versus the third quarter of last year.”

To supplement our consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), we sometimes use non-GAAP financial measures, such as free cash flow and the net debt to capitalization ratio, that we believe are appropriate to enhance an overall understanding of our historical financial performance and future prospects. The non-GAAP items, which are adjusted to exclude certain cash inflows and outlays, and include only certain balance sheet accounts from the comparable GAAP measures, are an indication of our performance in cash flow generation and also provide an indication of the Company's relative balance sheet leverage to other industrial manufacturing companies. These non-GAAP financial measures are among the primary indicators management uses as a basis for evaluating our cash flow generation and our capitalization structure. For these reasons, management believes these non-GAAP financial measures can be useful to investors, potential investors and others. The presentation of this additional information is not meant to be considered in isolation or as a substitute for changes in cash and cash equivalents prepared in accordance with GAAP. Please see Tables 1 and 2 of this press release.
