What happened 

Shares of Mueller Water Products, Inc. (NYSE:MWA) fell as much as 12.5% in trading on Friday after the company reported fiscal second-quarter results. At 2:55 p.m. EDT, shares were still down 10.8% on the day. 

So what

Net sales were up 1.3% to $119.7 million and adjusted income from continuing operations were up 42.6% to $15.4 million, or $0.09 per share. Mueller Technologies drove the growth with a 20.7% increase in sales to $18.1 million, offset by a small decline in Mueller Co. sales to $181.6 million.

Earnings per share hit analyst estimates on the market, but there was an expectation that Mueller would report $206.6 million in sales for the quarter. The miss on the top line is likely what traders are focused on today. 

Now what

Management said that bad weather in the western U.S. and weak international sales were the drivers of the worse-than-expected quarter. The weather was a temporary setback, but lagging international sales may be a long-term concern for investors. With weak growth and an uncertain international segment, I don't think shares look very attractive at 23 times this year's earnings estimates. For that reason, this isn't a discount I will be jumping on today.
