Mueller Water Products closed fiscal 2026 with a quarter that showed its margin engine still running while its growth engine stalled. Adjusted earnings of $0.38 per share missed the $0.39 consensus by 2.6% and were flat year over year. Revenue of $376.5 million fell 1.1% and missed the $383.05 million estimate by 1.7%. The miss was small, but the trajectory matters more. Sales had grown 4.6%, 5.5% and 4.1% in the first three quarters before turning negative in the fourth. Fiscal 2027 sales guidance of $1.44 billion to $1.47 billion also sits below the fiscal 2026 total. That is the central tension: management is promising another year of margin expansion on a revenue base that is barely growing.

The quality of the quarter deserves scrutiny. Adjusted EBITDA rose 4.0% to $95.5 million, and margin expanded 130 basis points to 25.4%. Much of that improvement came below gross profit. SG&A fell 14.1%, or $9.4 million, mainly because of lower incentive compensation and favorable personnel costs. Those savings are not obviously repeatable. Reported gross margin edged up to 37.0% from 36.8%, but the prior-year quarter carried a $5.6 million warranty charge. Excluding items, the call analysis puts underlying gross margin down roughly 100 basis points, as lower volumes, mix, tariffs and inflation outweighed pricing. A 28.0% tax rate, up from 23.4%, also kept GAAP EPS flat at $0.33 despite higher operating income.

The segments diverged sharply. Water Flow Solutions sales fell 3.0% on lower volumes, yet adjusted EBITDA margin jumped 300 basis points to 31.8% on manufacturing gains and pricing. The full-year segment margin reached a record 33.0%, evidence that foundry investments and the Decatur brass foundry closure are paying off. Water Management Solutions moved the other way. Sales rose 1.4%, entirely on price, while adjusted EBITDA fell 8.4% and margin dropped 270 basis points to 24.9%, down from a record 28.1% in the third quarter. Tariffs and lower volumes did the damage there.

The full year was strong. Adjusted EBITDA rose 14.1% to $372.2 million, at the top of a guidance range that management raised all year. Adjusted EPS climbed 19.8% to $1.57, and free cash flow reached $207.3 million, about 84% of adjusted net income. The fiscal 2027 outlook, however, depends heavily on portfolio actions:

• **Metering exit.** The business, transitioning to ZENNER USA, generated about $40 million of sales at a negative EBITDA margin. Management expects a 100 to 140 basis point annualized margin benefit beginning in the fiscal second quarter. The exit also brings roughly $26 million of one-time costs, mostly in the first quarter, and customer-migration timing is uncertain.
• **Margin and sales guidance.** Adjusted EBITDA of $378 million to $388 million implies a 26.3% margin, up 110 basis points. Excluding metering, sales are guided roughly flat to up 2.5%.
• **Volume headwinds.** Water Management Solutions sales are expected to fall by a high-single-digit percentage as the hydrant backlog benefit unwinds.
• **Offsets.** Management expects double-digit growth in specialty valves and plans a price increase in the fiscal second quarter.
• **Cost and cash flow items.** The tax rate is guided to 24% to 26%, and capex rises to $60 million to $70 million.

Demand messaging is where the release and the call diverge. The press release says municipal repair and replacement demand "remains resilient." On the call, that same end market, described as resilient through the first three quarters, was characterized as showing cautious purchasing. Residential construction also remains slow. Investors should weigh that shift in tone more heavily than the boilerplate. Inventories rose to $385.8 million from $328.7 million despite lower volumes, which is worth watching if demand softens further.

Capital returns provide a cushion. The board added $300 million to the buyback authorization, bringing the total to $334.5 million, and raised the dividend 14.3% to $0.08. The balance sheet supports both, with $566.0 million of cash against $453.8 million of debt and no maturities until 2029. A new CFO, Mike Morgan, is also joining.

The market was skeptical going in, and this report did little to change that. Investor sentiment was already negative and weakened moderately, from -0.57 to -0.68. Shares at $24.04 are down 11.7% since the opening after the August report and sit about 6.9% below the 200-day moving average of $25.83. The Earnings Whispers trend signals are mixed: price and AVWAP readings are negative, while momentum is positive.

The bottom line is that Mueller remains a high-quality margin story with a growth problem. Its record profitability, strong cash conversion and expanded buyback are real. However, the fourth quarter's margin gain leaned on non-recurring cost relief, underlying gross margin slipped, and fiscal 2027 margin expansion depends largely on exiting a money-losing business rather than on volume recovery. Until municipal purchasing and residential activity firm up, bears have legitimate ammunition.
