Is there a buying opportunity in IDEX, or does it present a risk to your portfolio? Get the full stock story straight from our expert analysts, it’s free.We're sitting this one out for now. Here are three reasons why we avoid IEX and a stock we'd rather own.
Why Do We Think IDEX Will Underperform?
Founded in 1988, IDEX (NYSE:IEX) is a global manufacturer specializing in highly engineered products such as pumps, flow meters, and fluidics systems for various industries.
1. Core Business Falling Behind as Demand Plateaus
In addition to reported revenue, organic revenue is a useful data point for analyzing Gas and Liquid Handling companies. This metric gives visibility into IDEX’s core business because it excludes one-time events such as mergers, acquisitions, and divestitures along with foreign currency fluctuations - non-fundamental factors that can manipulate the income statement.
Over the last two years, IDEX failed to grow its organic revenue. This performance was underwhelming and implies it may need to improve its products, pricing, or go-to-market strategy. It also suggests IDEX might have to lean into acquisitions to accelerate growth, which isn’t ideal because M&A can be expensive and risky (integrations often disrupt focus). 
2. EPS Barely Growing
We track the long-term change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.
IDEX’s unimpressive 5.8% annual EPS growth over the last five years aligns with its revenue performance. This tells us it maintained its per-share profitability as it expanded.
3. New Investments Fail to Bear Fruit as ROIC Declines
A company’s ROIC, or return on invested capital, shows how much operating profit it makes compared to the money it has raised (debt and equity).
We typically prefer to invest in companies with high returns because it means they have viable business models, but the trend in a company’s ROIC is often what surprises the market and moves the stock price. Unfortunately, IDEX’s ROIC averaged 4.3 percentage point decreases over the last few years. We like what management has done in the past, but its declining returns are perhaps a symptom of fewer profitable growth opportunities.
Final Judgment
IDEX doesn’t pass our quality test. That said, the stock currently trades at 25× forward price-to-earnings (or $215 per share). At this valuation, there’s a lot of good news priced in - we think there are better stocks to buy right now. Let us point you toward TransDigm, a dominant Aerospace business that has perfected its M&A strategy.
