Third Quarter Highlights:

·Third quarter 2012 sales were down 3% from the third quarter of 2011, driven largely by a negative foreign exchange effect of 5%.

·Organic sales growth in the third quarter of 2012 was approximately 2% over the third quarter of 2011, with increases of 3% in Europe, Middle East and Africa (EMEA) and 22% in Asia; North America was essentially flat quarter to quarter.

·Adjusted 2012 third quarter EPS of $0.63 was 19% above adjusted EPS for the second quarter of 2012 and 9% below adjusted EPS for the third quarter of 2011.  The third quarter of 2011 was the strongest EPS quarter in Company history. The tekmar acquisition contributed $0.01 of earnings in the third quarter of 2012.

·The impact on third quarter 2012 EPS from the share repurchase program was offset by weaker foreign exchange when compared to the third quarter of 2011.

·Adjusted operating margins decreased by 1.7 percentage points to 10.4% for the third quarter of 2012 as compared to the third quarter of 2011.

·Adjusted operating margins increased by 1.0 percentage point as compared to the second quarter of 2012, and by 2.5 percentage points as compared to the first quarter of 2012.

·Free cash flow increased by 38% to $56.0 million for the nine months ended September 30, 2012 as compared to the same period in 2011.  Through September 30, 2012, the 2012 cash conversion rate of free cash flow to net income is approximately 106%.

North America sales increased $1.8 million, or 1%, to $207.4 million in the third quarter of 2012, compared to $205.6 million for the third quarter of 2011.  This increase was primarily due to acquired sales of $2.6 million, or 1.3%, with essentially flat organic sales, offset partially by unfavorable foreign exchange movements.  The unfavorable foreign exchange was associated with the weakening of the Canadian dollar against the U.S. dollar.  Organic sales into the North American DIY home improvement market increased 4.2% for the third quarter of 2012 as compared to the third quarter of 2011 primarily from increased sales of residential and commercial flow control products and water quality products.  Organic sales into the North American wholesale market decreased by 1.3% during the third quarter as compared to the same period in 2011, primarily due to decreased sales of our residential and commercial flow control products.

EMEA sales decreased $12.8 million, or 8%, to $146.5 million for the third quarter of 2012, compared to $159.3 million for the third quarter of 2011.  This decrease was primarily due to unfavorable foreign exchange movements associated with the weakening of the euro versus the U.S. dollar of $17.8 million, or 11%, partially offset by an organic sales increase of $5.0 million, or 3%.  Organic sales in the EMEA wholesale market and OEM market each increased approximately 4% in the quarter compared to the third quarter of 2011.  EMEA segment sales

represented approximately 41% and 43% of total Company sales in the third quarters of 2012 and 2011, respectively.

Asia sales increased $1.4 million, or 24%, to $7.3 million for the third quarter of 2012, compared to $5.9 million for the third quarter of 2011.  This increase was primarily due to an organic sales increase in our HVAC and gas product line.

Operating income for the third quarter of 2012 was $33.1 million, which yielded an operating margin of 9.2%, compared to operating income in the third quarter of 2011 of $41.2 million, which yielded an operating margin of 11.1%.  Compared to the second quarter of 2012, operating margins increased by 0.1 percentage point from 9.1%.  On an adjusted basis, operating income in the third quarter of 2012 was $37.5 million compared to $44.9 million in the third quarter of 2011, a 16% decrease.  On an adjusted basis, operating margins decreased 1.7 percentage points to 10.4% in the third quarter of 2012, compared to 12.1% on an adjusted basis for the third quarter of 2011.  Compared to the second quarter of 2012, adjusted operating margins increased by 1.0 percentage point from 9.4%.

Consolidated sales for the first nine months of 2012 were $1,096.5 million, an increase of $20.1 million, or 2%, compared to the first nine months of 2011, primarily from acquired growth being partially offset by unfavorable foreign exchange.  Organic sales were up approximately 1%, with year-to-date growth in North America and Asia being partially offset by a reduction in EMEA.

David J. Coghlan, Chief Executive Officer, commented, “We were pleased with our improved sequential performance in the third quarter. As we had communicated earlier this year, we anticipated that our adjusted operating margin would trend up as we moved through 2012.  Our third quarter adjusted operating margins of 10.4% was 1.0 percentage point greater than our second quarter and 2.5 percentage points greater than our first quarter.  We attribute this trend to the sequential reduction in costs incurred related to the lead free production transition and, in general, to efforts to reduce costs in other areas.  We were also pleased with the efforts of our team in EMEA to grow sales organically during the quarter in a very difficult macroeconomic environment.  We continue to be encouraged by our growth initiatives in Asia.  We knew comparisons to the third quarter of 2011 would be difficult given the strong sales, favorable product mix and positive factory absorption we experienced last year. However, our overall third quarter 2012 results exceeded our expectations given the current market environment.”

Mr. Coghlan concluded, “We generated free cash flow of $56.0 million through the first nine months of 2012, an increase of approximately 38% as compared to free cash flow of $40.7 million for the same period in 2011.  The increase is primarily due to incremental cash provided by operations.  At September 30, 2012, our net debt to capitalization ratio was 16.1%, as compared to 13.9% at December 31, 2011, with the increase driven primarily by cash used to fund both the completed share repurchase program and the tekmar acquisition.  As of quarter

end, we had approximately $210 million of cash on hand and approximately $265 million in available credit under our credit agreement.”

In this press release we refer to non-GAAP financial measures (including adjusted operating income, adjusted operating margins, adjusted net income, adjusted earnings per share, free cash flow, net debt to capitalization ratio and the cash conversion rate of free cash flow to net income) and provide a reconciliation of those non-GAAP financial measures to the corresponding financial measures contained in our consolidated financial statements prepared in accordance with GAAP. We believe that these financial measures are appropriate to enhance an overall understanding of our historical financial performance and future prospects. Adjusted operating income, adjusted operating margins, adjusted net income and adjusted earnings per share eliminate certain expenses incurred in the periods presented that relate primarily to our global restructuring programs, asset impairment charges, CEO separation costs, CFO retention costs, significant legal and customs settlements, due diligence costs, acquisition accounting costs, tax adjustments, and other costs and related tax benefits. Management then utilizes these adjusted financial measures to assess the run-rate of the Company’s continuing operations against those of comparable periods without the distortion of those factors.  Free cash flow and the net debt to capitalization ratio, which is 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. The cash conversion rate of free cash flow to net income is also a measure of our performance in cash flow generation. 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. In addition, free cash flow is used as a criterion to measure and pay certain compensation-based incentives. For these reasons, management believes these non-GAAP financial measures can be useful to investors, potential investors and others. The Company’s non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial measures prepared in accordance with GAAP.
