North Andover, MA…February 9, 2017.  Watts Water Technologies, Inc. (NYSE: WTS) today announced results for the fourth quarter and year ended December 31, 2016.  Sales for the fourth quarter and the full year were $342 million and $1.4 billion, respectively, both down 5%, as compared to the similar periods of 2015.  Net income (loss) per diluted share (EPS) for the fourth quarter and year ended December 31, 2016 was $0.51 and $2.44, respectively, as compared to ($3.41) and ($3.24) for the fourth quarter and year ended December 31, 2015, respectively.  The significant increase in GAAP EPS in the fourth quarter was primarily due to a 2015 goodwill impairment charge.  The full year increase in GAAP EPS was primarily due to the 2015 goodwill impairment charge and the settlement of the Company’s pension plan and other benefit obligations.  Adjusted for special items, fourth quarter and year ended December 31, 2016 EPS was $0.64 and $2.67, respectively, as compared to $0.59 and $2.41 for the fourth quarter and year ended December 31, 2015, respectively.  Adjusted results improved due to strong operating performances in the quarter and during the year.   A summary of fourth quarter and full year financial results is as follows:

(1) Special items and adjusted earnings per share represent non-GAAP financial measures. For a reconciliation of GAAP to non GAAP items please see the tables attached to this press release.

Remarking on operating results, Chief Executive Officer, Robert J. Pagano Jr., said, “Our fourth quarter results were in line with our expectations.  We continued to expand operating margins and EPS despite flat organic growth.  Our transformation initiatives and on-going productivity focus drove the strong margin increase.  We had another strong year of free cash flow, once again exceeding net income.”

Commenting on the full year 2016, Mr. Pagano noted, “We made substantial progress in 2016, building on the foundation we previously established.  We continued to transform the Company by realigning our business teams and product platforms, getting closer to our customers, executing on restructuring initiatives and re-investing for future growth.  We also expanded our solutions offering for commercial boiler room applications with the acquisition of PVI Industries.  We achieved these results while significantly expanding our full year adjusted operating margin by 130 basis points through continued portfolio enhancement, productivity and other transformation initiatives.  We expect our efforts in 2016 will drive growth and further margin expansion in 2017 and beyond.”

Fourth Quarter Financial Highlights:

·                  Excluding the effect of fewer shipping days, organic sales were flat with the fourth quarter last year.  Regionally, organic sales adjusted for shipping days were flat in the Americas, down 1% in Europe, Middle East and Africa (EMEA), and up 18% in Asia-Pacific.  The Americas sales performance was impacted by anticipated headwinds in the retail channel which offset growth in our core plumbing and valves product lines.  EMEA sales were impacted by lower demand in our larger geographical markets, while Asia-Pacific grew substantially due to continued growth in the residential markets in China and in the commercial markets outside of China.

·                  Operating margin on a GAAP basis increased to 9.2%, compared to a negative margin of 32.9% in the fourth quarter of 2015.  Included in 2015 operating margin were a $130 million goodwill impairment charge related to EMEA and a $6 million charge to settle legacy product liability claims.  Adjusted operating margin increased 1.0 percentage point to 10.9% in the fourth quarter of 2016 compared to 2015, driven primarily by strong productivity resulting from our transformation initiatives.

·                  GAAP EPS of $0.51 was higher than the prior year quarter EPS of ($3.41) primarily driven by the 2015 charges for goodwill and product liability costs previously mentioned.  Adjusted EPS of $0.64 was 8% higher than 2015 as a result of improved operational performance, which more than offset a headwind from the exit of undifferentiated products.

·                  For 2016, operating cash flow was $138 million and net capital expenditures were $36 million, resulting in free cash flow of $102 million.  In 2015, operating cash flow was $109 million, net capital expenditures were $28 million and free cash flow was $82 million.  Operating cash flow in 2015 included a $49 million outflow for the settlement of the Company’s pension plan and other benefit obligations.

·                  The Company repurchased approximately 68,000 shares of Class A common stock at a cost of approximately $4 million during the fourth quarter of 2016.  For 2016, approximately 501,000 shares were purchased at a cost of approximately $27 million.  Approximately $56 million remains available for stock repurchases under the current stock repurchase program, which has no expiration date.

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, 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, deployment costs, acquisition related costs, gains on acquisition and disposition,  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, which allows for a more complete understanding of underlying sales trends by providing sales growth on a consistent basis. 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.
