Xylem Inc. reports second quarter 2013 results

WHITE PLAINS, N.Y., July 30, 2013 – Xylem Inc. (NYSE: XYL), a leading global water technology company dedicated to solving the world’s most challenging water issues, today reported second quarter 2013 net income of $46 million, or $0.25 per share. Adjusted net income was $66 million, or $0.36 per share, excluding the impact of special items that included restructuring and realignment charges, and special tax items. Second quarter revenue was $960 million, down $6 million from the second quarter 2012. Strength in the company’s U.S. residential, commercial and agriculture business was more than offset by continued softness in Europe, as well as in the public utilities and industrial markets. Second quarter 2013 adjusted operating margins were 10.2 percent, excluding the impact of restructuring and realignment costs, down 380 basis points resulting from lower volume and continued investments in growth initiatives, the unfavorable impact of foreign exchange rates, and other items.

“While our second quarter results were lower than expected, we captured important contract wins in June, resulting in record orders of more than $1 billion in the quarter,” said Gretchen McClain, president and chief executive officer of Xylem Inc. “We continue to take strong and decisive actions to position the company for efficient operation and profitable growth. While we’re seeing the initial benefits from our on-going restructuring and organizational realignment, we are accelerating additional short- and long-term actions to further reduce our cost base and drive more efficiencies throughout our business.”

McClain said the company expects to benefit from investments in growth initiatives and from continued efforts to transform the business and improve growth execution.

“We are encouraged by our second quarter order rate and several new products that we launched during the second quarter, including our ‘smart’ dewatering solutions from Flygt and Godwin that are efficient, compact and meet our customers’ needs for

more reliable and durable technologies,” McClain said. “These new products and some key contract wins give us confidence in an improved second half of the year and position us for long-term growth.”

Notable business wins in the second quarter include:

Full-year 2013 Outlook

Xylem’s full-year revenues are now expected to be approximately $3.7 billion, and adjusted net income is expected to be in the range of $260 to $279 million, or $1.40 to $1.50 per share, down from the earlier projection of adjusted net income of $1.79 to $1.89 per share. Full-year GAAP net income is now anticipated to be in the range of $205 to $237 million, or $1.10 to $1.27 per share, which includes $60 to $80 million of restructuring and realignment costs.

Xylem Inc. Non-GAAP Measures

Management views key performance indicators including revenue, gross margins, segment operating income and margins, orders growth, free cash flow, working capital, and backlog, among others. In addition, we consider certain measures to be useful to management and investors evaluating our operating performance for the periods presented, and provide a tool for evaluating our ongoing operations, liquidity and management of assets. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives. These metrics, however, are not measures of financial performance under GAAP and should not be considered a substitute for revenue, operating income, net income, earnings per share (basic and diluted) or net cash from operations as determined in accordance with GAAP. We consider the following non-GAAP measures, which may not be comparable to similarly titled measures reported by other companies, to be key performance indicators:

“Organic revenue” and “Organic orders” defined as revenue and orders, respectively, excluding the impact of foreign currency fluctuations, intercompany transactions, and contributions from acquisitions and divestitures. Divestitures include sales of portions of our business that did not meet the criteria for classification as a discontinued operation or insignificant portions of our business that we did not classify as a discontinued operation. The period-over-period change resulting from foreign currency fluctuations assumes no change in exchange rates from the prior period.

“Constant currency” defined as financial results adjusted for currency translation impacts by translating current period and prior period activity using the same currency conversion rate. This approach is used for countries whose functional currency is not the U.S. dollar.

“EBITDA” defined as earnings before interest, taxes, depreciation, amortization expense, and share-based compensation. “Adjusted EBITDA” reflects the adjustment to EBITDA to exclude for non-recurring separation costs associated with the Xylem spin-off from ITT Corporation as well as non-recurring restructuring and realignment costs.

“Adjusted Operating Income,” “Adjusted Segment Operating Income,” and “Adjusted EPS” defined as operating income and earnings per share, adjusted to exclude non-recurring separation costs associated with the Xylem spin-off from ITT Corporation, non-recurring restructuring and realignment costs and tax-related special items.

“Normalized EPS” defined as adjusted earnings per share, as well as adjustments to reflect the incremental current period amount of interest expense and stand-alone costs in the prior comparable period.

“Free Cash Flow” defined as net cash from operating activities, as reported in the Statement of Cash Flow, less capital expenditures as well as adjustments for other significant items that impact current results which management believes are not related to our ongoing operations and performance. Our definition of free cash flows does not consider non-discretionary cash payments, such as debt.

“Realignment costs” defined as non-recurring costs not included in restructuring costs that are incurred as part of actions taken to reposition our business, including items such as professional fees, relocation, travel and other costs.
