Xylem Inc. (XYL) had a rough Tuesday. The water technology company reported third-quarter results that fell short of Wall Street's expectations and then proceeded to lower its full-year outlook and issue fourth-quarter guidance that was well below estimates. Investors responded by sending the stock down 11.79% to $95.47, a new 52-week low.

Let's break down the numbers. Adjusted earnings per share came in at $1.44, just a penny shy of the $1.45 consensus. Revenue totaled $2.201 billion, missing the $2.276 billion analysts were looking for. Not catastrophic misses, but enough to rattle confidence in a company that's supposed to be riding secular tailwinds like water scarcity and infrastructure spending.

Orders Up, Revenue Flat: A Mixed Bag

Here's the interesting part: organic orders rose 10%, driven by demand for metering solutions and data center projects. Backlog increased 13% to $5.5 billion. That suggests the future pipeline is healthy. But organic revenue was largely unchanged from a year earlier, as weakness in Measurement and Control Solutions, Water Infrastructure, and Water Solutions and Services offset gains elsewhere.

Adjusted EBITDA margin expanded 70 basis points to 23.9%, helped by pricing and productivity improvements. Free cash flow was $444 million, and net debt to adjusted EBITDA ticked up to 1.1 times following share repurchases. So the underlying profitability story isn't broken, but the top line is stalling.

Segment-by-Segment: Where the Cracks Showed

• Measurement and Control Solutions: Organic orders surged 30%, but organic revenue declined 5%. Adjusted EBITDA margin expanded 270 basis points to 24.5%. The segment's $1.3 billion backlog supports deployments in late 2027 and 2028, so this is more about timing than demand.
• Water Infrastructure: Organic orders fell 1% amid treatment project delays and weakness in China. Organic revenue declined 1%, while adjusted EBITDA margin improved 180 basis points to 26.2%.
• Applied Water: Organic orders rose 15%, with data center orders increasing more than 200%. Organic revenue grew 9%, but adjusted EBITDA margin contracted 40 basis points due to inflation, product mix, and growth investments.
• Water Solutions and Services: Organic orders increased 6%, but organic revenue declined 2% amid slower project ramp-ups. Adjusted EBITDA margin fell 140 basis points to 24.9%. Management attributed the weakness to project timing rather than slowing demand.

Portfolio Shake-Up and a Big Amazon Deal

Xylem also announced some strategic moves. It plans to divest its Applied Water International and Specialty Flow Control businesses, including beverage and marine operations, as part of a broader portfolio restructuring. These businesses account for about 9% of revenue but less than 5% of EBITDA. The changes are expected to reduce China's share of company revenue to 1% from 2%.

Effective Jan. 1, 2027, Xylem will transition to a three-segment reporting structure and direct capital toward higher-growth, higher-margin markets. The company also secured an ultrapure water treatment project for a leading semiconductor manufacturer's fabrication facility in the United States. And separately, Xylem is expanding its relationship with Amazon.com, Inc. (AMZN) to provide water treatment solutions for data centers worldwide. That's a notable vote of confidence in Xylem's ability to serve the tech sector's insatiable water needs.

Guidance Slashed

Now for the bad news. Xylem lowered its full-year adjusted earnings guidance to $5.40 to $5.45 per share from its previous forecast of $5.55 to $5.70. The revised outlook falls below the analyst consensus estimate of $5.66 per share. The company also reduced its 2026 revenue forecast to $8.95 billion from $9.2 billion, compared with Wall Street expectations of $9.191 billion.

Xylem now expects flat organic revenue growth, down from its previous forecast of 2% to 3% growth. Adjusted EBITDA margin is projected to reach 23.2%, an improvement of 100 basis points. Free cash flow margin is expected to be 10.2%, at the low end of the company's previous guidance range.

Fourth-Quarter Outlook Falls Short

For the fourth quarter, Xylem expects adjusted earnings of $1.39 to $1.44 per share, below the analyst consensus estimate of $1.63. The company forecasts revenue of $2.3 billion, compared with expectations of $2.446 billion. Revenue is expected to decline 5% from a year earlier, with organic revenue falling 1% to 2%. Adjusted EBITDA margin is projected to reach 24.5%, up 130 basis points.

Measurement and Control Solutions revenue is expected to decline sequentially before stabilizing. Water Solutions and Services is projected to return to low-single-digit growth despite continued timing challenges involving large projects.

So where does that leave investors? Xylem is still a quality industrial with a strong backlog and growing orders, but the near-term execution is clearly bumpy. The stock's plunge to a 52-week low reflects frustration with the pace of revenue conversion and the lowered guidance. Management is betting that portfolio changes and data center demand will right the ship, but for now, the market isn't buying it.
