Mueller Water walks away from meters to chase a fatter margin

Mueller Water Products just chose to get smaller. Alongside record fourth-quarter and full-year results on 4 November, the Atlanta-based company said it will move its metering business to ZENNER USA, part of the Minol-ZENNER Group.

What's changing

The metering business runs through Mueller's Mueller Systems subsidiary and sits in its Water Management Solutions segment. Customers will move across to ZENNER USA, which will supply replacement software and hardware so that Mueller can keep its existing commitments. The transition starts straight away.

Mueller said the decision followed a board and management review of how well the unit fitted and performed. It expects a 100 to 140 basis point annualised lift to adjusted EBITDA margin, mostly from the second quarter of fiscal 2027. Getting there costs about $26 million of one-time expenses in fiscal 2027, covering warranty liability, customer service, transaction costs, severance and write-offs, with most of it landing in the first quarter. No price or headcount figure was given.

"We are taking this step to sharpen Mueller's focus and strengthen the Company for the future," said Paul McAndrew, President and Chief Executive Officer.

The numbers

Fourth-quarter net sales slipped 1.1% to $376.5 million, as lower volumes outweighed higher prices. Profit went the other way: adjusted EBITDA rose 4.0% to $95.5 million and the margin widened to 25.4%. Water Flow Solutions, the valves and hydrants side, saw sales fall 3.0% to $210.9 million but lifted its adjusted EBITDA margin to 31.8%. Water Management Solutions grew sales 1.4% to $165.6 million, while its margin fell to 24.9%.

For the full year, net sales rose 3.2% to $1,475.0 million and adjusted EBITDA climbed 14.1% to $372.2 million. Free cash flow rose 20.5% to $207.3 million.

The 2027 guide

Mueller expects fiscal 2027 net sales of $1,440 million to $1,470 million, excluding metering, which brought in about $40 million in fiscal 2026. Adjusted EBITDA is guided at $378 million to $388 million, implying a 26.3% margin at the midpoint. StockStory noted that the sales midpoint came in 3.8% below consensus, while the EBITDA guide was in line.

The bigger picture

This follows the $300 million buyback expansion and 14.3% dividend rise Mueller announced in October, which we covered in Vol 1. The pattern is consistent: a supplier with plenty of cash, flat volumes and a clear view that margin beats breadth. Xylem's planned divestitures, covered last week, point the same way. For the meter market, it means Mueller's installed base of utility customers moving to a new supplier over the coming year, with $566 million of cash still sitting on Mueller's balance sheet at year-end.

What it means for hiring

We think a customer transition of this kind needs experienced meter and AMI account managers on both sides, and ZENNER USA may need to add service and sales capacity to support the customers it takes on.
Mueller says it is building a more streamlined organisation through portfolio optimisation. In our view that puts a premium on product and commercial leaders in valves, hydrants and network monitoring who can grow price and mix, not just volume.
Exits like this usually bring capable metering specialists to market, which is a good moment for other meter, AMI and leak-detection suppliers to strengthen their teams.
