Xylem Inc. reports strong fourth quarter and full year 2015 results

Company also announces $69 million acquisition of Tideland Signal Corporation and

a 10-percent increase in its quarterly cash dividend

RYE BROOK, N.Y., February 4, 2016 – Xylem Inc. (NYSE: XYL), a leading global water technology company dedicated to solving the world’s most challenging water issues, today reported fourth quarter 2015 net income of $114 million, or $0.63 per share. Excluding the impact of restructuring, realignment and other special items, the Company delivered adjusted net income of $108 million or $0.60 per share in the quarter, a three-percent increase over the prior year period excluding foreign exchange translation impact. Fourth quarter revenue was $994 million, up two percent organically, reflecting continued growth in the municipal and construction markets. Fourth quarter adjusted operating margin was flat year-over-year as continued improvements from cost savings initiatives were offset by headwinds from inflation as well as geographic and product mix.

For the full year 2015, Xylem generated $3.65 billion in revenue, up two percent organically. Full-year reported net income was $340 million, or $1.87 per share, with an operating margin of 12.3 percent. Adjusted net income, which excludes the impact of restructuring, realignment and other special items, was $336 million, or $1.85 per share, a five-percent increase over the prior year excluding foreign exchange translation impact. Xylem delivered a full-year 2015 adjusted operating margin of 12.9 percent, flat to prior year. The Company generated $347 million in free cash flow, an increase of 17 percent versus last year, representing a conversion of 105 percent of net income.

“We closed out 2015 with strong results, delivering on our financial commitments, executing well in the marketplace and advancing our long-term growth initiatives,” said Patrick Decker, President and Chief Executive Officer of Xylem. “We made significant progress in decidedly mixed market conditions. We are encouraged by the continuing strength we see in the public utility sector, particularly in the U.S. and key emerging markets where pent-up demand for water and wastewater infrastructure helped us to generate eight-percent growth in this end market globally in the quarter. This strength offset declines in heavy industry, specifically oil and gas and mining, where our exposure is limited.”

Xylem today also announced the acquisition of Tideland, a leading producer of analytics solutions in the coastal and ocean management sectors. Based in Texas, the business also has key locations in the

Netherlands, United Kingdom and Singapore, and provides marine navigation and environmental monitoring systems and products to a variety of ports and harbors, offshore energy companies, and coastal and marine authorities.

Decker continued, “This latest acquisition adds another complementary set of offerings to our analytics portfolio. That, in combination with the $50 million in share repurchases in the fourth quarter and 10-percent increase in our quarterly dividend announced today, illustrates our continued focus on executing a balanced capital deployment strategy. As we look ahead in 2016, we remain focused on advancing our key growth initiatives, including driving sales excellence, increasing our research and development investment, and accelerating business simplification to accelerate Xylem’s growth and enhance shareholder value.”

Xylem announced that its Board of Directors declared a dividend in the amount of $0.1549 per share, an increase of 10 percent. The dividend is payable on March 16, 2016 to shareholders of record as of February 18, 2016.

Full-year 2016 Outlook

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

Full-year 2016 adjusted operating income is expected to be in the range of $493 to $515 million, resulting in adjusted earnings per share of $1.95 to $2.05. This represents an increase of five to 11 percent from Xylem’s 2015 adjusted results. Excluding projected unfavorable impacts of foreign exchange translation, Xylem’s adjusted earnings per share growth is anticipated to be in the range of eight to 13 percent. The Company’s adjusted earnings outlook excludes 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 legal and professional fees, associated with the Korea matters, as well as costs incurred for the contractual indemnification of tax obligations to ITT.

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