Xylem Inc. reports solid first quarter earnings

RYE BROOK, N.Y., May 3, 2016 – Xylem Inc. (NYSE: XYL), a leading global water technology company dedicated to solving the world’s most challenging water issues, today reported first quarter 2016 net income of $66 million, or $0.37 per share. Excluding restructuring and realignment charges and other special items, adjusted net income was $62 million or $0.35 per share, an increase of two cents or six percent from the comparable period in 2015. First quarter revenue was $847 million, up four percent on an organic basis, reflecting strength in the U.S. public utility and commercial building markets and growth across all key regions. Excluding restructuring and realignment charges and other special items, first quarter adjusted operating margin improved 10 basis points, driven by continued improvement in operating efficiencies. Excluding the impact of acquisitions, adjusted operating margin expanded 40 basis points in the quarter.

“We are off to a solid start in 2016 as our teams’ strong project execution helped accelerate our performance in mixed market conditions,” said Patrick Decker, President and Chief Executive Officer of Xylem. “Our top-line growth in the quarter reflects the benefits of our diversified end-market exposure. We are pleased with the continuing strength we see in the global public utility market, up 12 percent in the quarter, and we believe this market in the U.S. is in the early stages of a long-term recovery. In the industrial end market, we were able to offset ongoing headwinds from the oil and gas and mining sectors to bring our total industrial results to flat. And our teams delivered double-digit revenue growth in India and the Middle East, driving two-percent top-line growth in our Emerging Markets.”

Decker continued, “The fundamentals of our core business continue to improve and we are realizing the benefits of our cost savings and productivity initiatives across our businesses, enabling us to invest more in our strategic growth initiatives to drive greater shareholder value.”

Full-year 2016 Outlook

Xylem reaffirmed its forecast of full-year 2016 revenue of approximately $3.7 billion, including approximately one-percent growth from completed acquisitions and the unfavorable impacts of foreign exchange. On an organic basis, Xylem’s revenue growth is anticipated to be in the range of two to four percent.

The Company also reaffirmed its full-year 2016 adjusted operating income projection of $493 to $515 million. Full-year 2016 adjusted EPS are now expected to be in the range of $1.98 to $2.08, reflecting the interest savings from the Company’s recent refinancing of its 3.55% senior notes. This range represents growth of nine to 15 percent, excluding foreign exchange translation. The Company’s adjusted earnings outlook continues to exclude projected restructuring and realignment costs of approximately $25 million for the year.

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 fluctuations in foreign currency translation 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 restructuring and realignment costs, gain on sale of business and special charges.

“Adjusted Operating Income”, “Adjusted Segment Operating Income”, and “Adjusted EPS” defined as operating income, segment operating income and earnings per share, adjusted to exclude restructuring and realignment costs, gain on sale of businesses, special charges and tax-related special items, as applicable.

“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 costs not included in restructuring costs that are incurred as part of actions taken to reposition our business, including items such as professional fees, severance, relocation, travel, facility set-up and other costs.

“Special charges” defined as costs incurred by the Company, such as initial acquisition related costs, costs incurred for the contractual indemnification of tax obligations to ITT and other special non-operating items.

“Tax-related special items” defined as tax items, such as tax return versus tax provision adjustments, tax exam impacts, tax law change impacts, significant reserves for cash repatriation and other discrete tax adjustments.
