Company Overview

Founded as a supplier of motors, W.W. Grainger (NYSE:GWW) provides maintenance, repair, and operating (MRO) supplies and services to businesses and institutions.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, W.W. Grainger grew its sales at a solid 9.1% compounded annual growth rate. Its growth beat the average industrials company and shows its offerings resonate with customers.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. W.W. Grainger’s recent performance shows its demand has slowed as its annualized revenue growth of 5.1% over the last two years was below its five-year trend. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs.

We can better understand the company’s sales dynamics by analyzing its organic revenue, which strips out one-time events like acquisitions and currency fluctuations that don’t accurately reflect its fundamentals. Over the last two years, W.W. Grainger’s organic revenue averaged 5.7% year-on-year growth. Because this number aligns with its two-year revenue growth, we can see the company’s core operations (not acquisitions and divestitures) drove most of its results.

This quarter, W.W. Grainger reported year-on-year revenue growth of 10.1%, and its $4.74 billion of revenue exceeded Wall Street’s estimates by 3.6%.

Looking ahead, sell-side analysts expect revenue to grow 4.7% over the next 12 months, similar to its two-year rate. This projection doesn't excite us and suggests its newer products and services will not lead to better top-line performance yet.

Operating Margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

W.W. Grainger has been an efficient company over the last five years. It was one of the more profitable businesses in the industrials sector, boasting an average operating margin of 14.6%. This result isn’t surprising as its high gross margin gives it a favorable starting point.

Analyzing the trend in its profitability, W.W. Grainger’s operating margin rose by 1.6 percentage points over the last five years, as its sales growth gave it operating leverage. Its expansion was impressive, especially when considering most Maintenance and Repair Distributors peers saw their margins plummet.

This quarter, W.W. Grainger generated an operating margin profit margin of 16.7%, up 1.1 percentage points year on year. The increase was encouraging, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

W.W. Grainger’s EPS grew at 21.4% compounded annual growth rate over the last five years, higher than its 9.1% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

Diving into W.W. Grainger’s quality of earnings can give us a better understanding of its performance. As we mentioned earlier, W.W. Grainger’s operating margin expanded by 1.6 percentage points over the last five years. On top of that, its share count shrank by 9.9%. These are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For W.W. Grainger, its two-year annual EPS growth of 1.3% was lower than its five-year trend. We hope its growth can accelerate in the future.

In Q1, W.W. Grainger reported EPS of $11.65, up from $9.86 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects W.W. Grainger’s full-year EPS of $37.18 to grow 20.8%.
