North Andover, MA…November 2, 2018.  Watts Water Technologies, Inc. (NYSE: WTS) today announced third quarter 2018 results.

Remarking on operating results, Chief Executive Officer, Robert J. Pagano Jr., noted, “I am very pleased with our overall results for the third quarter as we continued to drive top-line growth and productivity, led by a strong performance in the Americas. We again delivered records for sales, adjusted operating margin and adjusted EPS in the quarter.  Operating margin continued to benefit from increased volume, price and productivity initiatives.  For the first nine months of 2018, organic sales growth approximated 6%, adjusted operating earnings have grown double digits and adjusted operating margin increased 30 basis points.  We are increasing our second half organic sales outlook after another strong quarterly performance.”

Sales during the third quarter of $391 million increased 7% compared to the same period in 2017. Third quarter net income per diluted share (EPS) on a GAAP basis was $0.92 as compared to $0.77 for the same period last year.  Adjusted for special items, third quarter EPS was $0.99 as compared to $0.80 for the same period last year.  Both GAAP and adjusted EPS increases were attributable to higher price, volume, productivity, a lower effective tax rate and reduced non-operating expenses.  GAAP EPS was negatively impacted by a higher restructuring charge.  A summary of third quarter financial results is as follows:

Financial Highlights

·                  Sales increased 7% and 8% on a reported and organic basis, respectively, compared to the third quarter last year; reported operating margin decreased 10 basis points and adjusted operating margin expanded 30 basis points. Regionally:

·                  Americas’ sales increased 10% on a reported and organic basis with growth in plumbing, drains and heating and hot water products.  Sales growth was driven by incremental price and higher volume.  Reported and adjusted operating income increased to $45 million, or 17.1% of revenue for the third quarter of 2018. Operating margin increased 50 and 20 basis points on a reported and adjusted basis, respectively. Operating margin benefited from price, volume and productivity, partially offset by growth investments and inflationary pressures from commodities and transportation costs. Reported operating margin also benefited from lower restructuring charges.

·                  Europe’s sales for the third quarter were up 2% on a reported basis and 4% on an organic basis.  The increase was driven by volume growth in drains and electronics products which more than offset product rationalization(1). Reported operating margin decreased 390 basis point to 8.4%, primarily related to $3.4 million of restructuring charges. Adjusted operating margin decreased 130 basis points to 11.5%, mostly driven by unfavorable sales mix, increased investments, and inflationary pressures.

(1)  Product rationalization represents the exit of low-margin, non-core products.

·                  Asia-Pacific, Middle East, and Africa (“APMEA”) reported sales were flat compared to the third quarter of 2017 and increased 3% on an organic basis.  Sales increases were driven by higher volume in the Middle East and Africa, Australia and Korea, partially offset by weak China sales and planned product rationalization(1).  Reported and adjusted operating margin increased to 15.1% or 1,210 basis points and 1,080 basis points, respectively.  The increases were driven by a significant increase in affiliate volume, productivity savings, favorable foreign exchange and sales mix, which more than offset planned investments and inflation.

·                  For the first nine months of 2018, operating cash flow was $67 million, net capital expenditures were $24 million and free cash flow was $43 million.  In the comparable period last year, operating cash flow was $73 million, net capital expenditures were $17 million and free cash flow was $57 million.  Free cash flow decreased due to increased inventory, tax payments and capital expenditures.  We expect sequential improvement in free cash flow during the fourth quarter of 2018, due to normal seasonality.

·                  The Company repatriated $11 million in cash during the third quarter.  For the first nine months of 2018, $121 million has been repatriated, a majority of which was used to pay down revolving debt.

·                  The Company repurchased approximately 57,000 shares of Class A common stock at a cost of approximately $4.7 million during the third quarter.  Year-to-date, we have purchased approximately 196,000 shares at a cost of $15.5 million, which offset dilution from our stock compensation programs.

Key Performance Indicators and Non-GAAP Measures

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, organic sales, free cash flow, cash conversion rate of free cash flow to net income and net debt to capitalization ratio) 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 enhance the overall understanding of our historical financial performance and give insight into our future prospects. Adjusted operating income, adjusted operating margins, adjusted net income and adjusted earnings per share eliminate certain expenses incurred and gains recognized in the periods presented that relate primarily to our global restructuring programs, deployment costs, acquisition related costs, and the related income tax impacts on these items, and other tax adjustments. Management then utilizes these adjusted financial measures to assess the run-rate of the Company’s operations against those of comparable periods.  Organic sales growth is a non-GAAP measure of sales growth excluding the impacts of foreign exchange, acquisitions and divestitures from period-over-period comparisons. Management believes reporting organic sales growth provides useful information to investors, potential investors and others, and allows for a more complete understanding of underlying sales trends by providing sales growth on a consistent basis. Free cash flow, cash conversion rate of free cash flow to net income, 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. 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.
