Why Does Parker-Hannifin Spark Debate?
Founded in 1917, Parker Hannifin (NYSE:PH) is a manufacturer of motion and control systems for a wide variety of mobile, industrial and aerospace markets.
Two Positive Attributes:
1. Operating Margin Reveals a Well-Run Organization
Operating margin is one of the best measures of profitability because it tells us how much money a company takes home after procuring and manufacturing its products, marketing and selling those products, and most importantly, keeping them relevant through research and development.
Parker-Hannifin has been a well-oiled machine over the last five years. It demonstrated elite profitability for an industrials business, boasting an average operating margin of 18.2%. This result isn’t too surprising as its gross margin gives it a favorable starting point.

2. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
Parker-Hannifin’s EPS grew at an astounding 20.7% compounded annual growth rate over the last five years, higher than its 8.1% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

One Reason to be Careful:
Slow Organic Growth Suggests Waning Demand In Core Business
In addition to reported revenue, organic revenue is a useful data point for analyzing Gas and Liquid Handling companies. This metric gives visibility into Parker-Hannifin’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, Parker-Hannifin’s organic revenue averaged 2.1% year-on-year growth. This performance was underwhelming and suggests it may need to improve its products, pricing, or go-to-market strategy, which can add an extra layer of complexity to its operations. 
Final Judgment
Parker-Hannifin’s positive characteristics outweigh the negatives, and with its shares topping the market in recent months, the stock trades at 29.2× forward P/E (or $885.46 per share). Is now a good time to buy? See for yourself in our full research report, it’s free for active Edge members.
