North Andover, MA….July 30, 2013.  Watts Water Technologies, Inc. (NYSE: WTS) today announced results for the second quarter ended June 30, 2013.  Net income per diluted share (EPS) for the second quarter of 2013 was $0.53.  Adjusting for special items, second quarter 2013 adjusted EPS was $0.57, compared to second quarter 2012 adjusted EPS of $0.52.  A summary of second quarter financial results is as follows:

All financial information and period-to-period references are on a continuing operations basis unless otherwise noted.  Reconciliations to generally accepted accounting principles (GAAP) and non-GAAP reconciliations are provided in the attached financial tables.

Second Quarter Highlights:

·                  Second quarter 2013 sales increased 1% from the second quarter of 2012, evenly split between organic growth and benefits from foreign exchange. Organic sales growth in North America of 3.0% and Asia of 26.2% was substantially offset by a reduction in Europe, Middle East and Africa (EMEA) of 4.5%.

·                  Adjusted 2013 second quarter EPS was $0.57, an increase of $0.05, or 10%, over adjusted EPS for the second quarter of 2012.  Net accretion from share repurchase programs contributed $0.01 to adjusted EPS in the second quarter of 2013.

·                  Adjusted operating margins increased by 0.7 percentage points to 10.1% for the second quarter of 2013 as compared to the second quarter of 2012; operating margins on a GAAP basis increased 0.6 percentage points to 9.6%, as compared to the second quarter of 2012.

·                  The Company repurchased approximately 212.6 thousand shares of Company stock during the second quarter, at a cost of $10 million, as part of the previously announced share repurchase program.

·                  Free cash flow was $4.7 million for the six months ended June 30, 2013, as compared to $14.3 million for the six months ended July 1, 2012; the decrease was primarily driven by an inventory increase and additional capital spending, both related to the Company’s investment in the lead free initiative.

North American sales increased $6.3 million, or 2.9%, to $224.4 million in the second quarter of 2013, compared to $218.1 million for the second quarter of 2012.  This increase was primarily due to an organic sales increase of $6.5 million, or 3.0%, offset partially by unfavorable foreign exchange movements of $0.2 million associated with the weakening of the Canadian dollar against the U.S. dollar.  Sales into the North American wholesale and OEM markets increased organically by 3.9% during the second quarter of 2013 as compared to the same period in 2012, primarily from increased sales in our residential and commercial flow control and HVAC and gas product lines.  Organic sales into the North American DIY home improvement market decreased 0.7% for the second quarter of 2013 as compared to the second quarter of 2012 primarily from decreased sales in our residential and commercial flow control product lines.

EMEA sales decreased $4.2 million or 2.9% to $138.6 million for the second quarter of 2013, compared to $142.8 million for the second quarter of 2012.  This decrease was primarily due to an organic sales decrease of $6.4 million, or (4.5%), partially offset by favorable foreign exchange movements associated with the strengthening of the euro versus the U.S. dollar of $2.2 million.  Organic sales in the EMEA wholesale market were down 1.1% in the quarter, and OEM sales decreased by 7.1% compared to the second quarter of 2012.  EMEA segment sales represented approximately 37.3% and 38.9% of total Company sales in the second quarters of 2013 and 2012, respectively.

Asia sales increased $1.8 million or 27.7% to $8.3 million for the second quarter of 2013, compared to $6.5 million for the second quarter of 2012.  This increase was primarily due to an organic sales increase of $1.7 million, or 26.2%, relating to residential valve and heating products.

Adjusted operating income for the second quarter of 2013 increased by $3.2 million, or 9.3%, to $37.6 million, as compared to the second quarter of 2012.  In North America, adjusted operating margins increased by 1.9 percentage points to 14.1% with revenue growth, favorable product mix and cost controls driving the margin improvement.  EMEA adjusted operating margins decreased by 0.6 percentage points to 8.4% in the second quarter of 2013 as compared to the second quarter of 2012, as the sales volume reduction caused plant absorption issues and the operating expense decrease did not keep pace with the sales decline.  Asia’s adjusted operating margins decreased 3.4 percentage points to 28.9% primarily due to product mix.

During the second quarter of 2013, the Company repurchased $10 million of its shares on the open market as part of the $90 million share repurchase program announced in April.  Shares repurchased totaled 212.6 thousand.  The net accretion effect of all share repurchase programs contributed $0.01 to adjusted EPS during the second quarter of 2013.

Consolidated sales for the first six months of 2013 were $733.4 million, an increase of $4.8 million, or 0.7%, compared to the first six months of 2012.  Organic sales were essentially flat, with growth in North America and Asia being offset by a reduction in EMEA, while foreign exchange contributed to the favorable increase in sales.

Free cash flow for the first six months of 2013 decreased by $9.6 million, to $4.7 million, as compared to the first six months of 2012.  The decrease related primarily to the Company’s ongoing lead free investment.  The Company increased lead free inventories in anticipation of customer transitions to lead free products and invested incremental capital on its lead free foundry.

David J. Coghlan, Chief Executive Officer, commented, “Our organic growth in the North American wholesale and OEM markets was solid during the second quarter due to continued expansion in new residential construction and a stable repair and replace end market.  We made good progress with our lead free initiative, commissioning the new foundry in June.  In EMEA, we saw continued declines in the French and German markets, partially offset by continued growth from export sales into the Middle East, Eastern Europe and our drains business.  Asia’s 26.2% organic sales growth was driven principally by residential plumbing and heating product sales.  As the year continues, EMEA will continue to be challenged by macro-economic issues and we are taking the appropriate costs actions to deal with the expected volume decline.  We expect to see further acceleration of our North America customers’ transitioning to lead free products and continued strong growth in our Asian business.”

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, a significant customs settlement, 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 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. 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.
