Evaluating Pentair (PNR) After Barclays’ Downgrade: Is the Stock’s Growth Story Fully Priced In?

Barclays just took Pentair (PNR) down a notch, shifting its rating to Equal Weight and indicating that the easy margin gains might be behind it. This puts more pressure on future revenue growth.

See our latest analysis for Pentair.

That cooler tone from Barclays seems to have taken some of the heat out of Pentair’s recent momentum, with a roughly flat year to date share price return but a striking three year total shareholder return of about 135 percent showing the longer term story is still firmly intact.

If this downgrade has you rethinking where growth and conviction might come from next, it could be a good time to explore fast growing stocks with high insider ownership.

With shares treading water this year but still trading at a modest discount to average analyst targets, investors now face a key question: is Pentair quietly undervalued, or is the market already baking in the next leg of growth?

Another Lens on Value

On simple earnings multiples, Pentair looks anything but cheap. Its P/E of 26.1 times sits above peers at 23.2 times, the wider US Machinery group at 25.5 times, and even our 25.9 times fair ratio, suggesting little margin of safety if sentiment cools.
