Company Overview
Credited with the invention of the glass-lined water heater, A.O. Smith (NYSE: AOS) manufactures water heating and treatment products for various industries.
Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Unfortunately, A. O. Smith’s 3.4% annualized revenue growth over the last five years was sluggish. This fell short of our benchmark for the industrials sector and is a rough starting point for our analysis.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. A. O. Smith’s performance shows it grew in the past but relinquished its gains over the last two years, as its revenue fell by 1.6% annually. 
This quarter, A. O. Smith’s $1.00 billion of revenue was flat year on year but beat Wall Street’s estimates by 1.4%.
Looking ahead, sell-side analysts expect revenue to grow 5.2% over the next 12 months. Although this projection indicates its newer products and services will fuel better top-line performance, it is still below the sector average.

Operating Margin
A. O. Smith’s operating margin has more or less stayed the same over the last 12 months , averaging 18.4% over the last five years. This profitability was elite for an industrials business thanks to its efficient cost structure and economies of scale. This result isn’t surprising as its high gross margin gives it a favorable starting point.
Analyzing the trend in its profitability, A. O. Smith’s operating margin might have fluctuated slightly but has generally stayed the same over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability.
This quarter, A. O. Smith generated an operating margin profit margin of 18.9%, down 1.4 percentage points year on year. Since A. O. Smith’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.
Earnings Per Share
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth — for example, a company could inflate its sales through excessive spending on advertising and promotions.
A. O. Smith’s EPS grew at 6.4% compounded annual growth rate over the last five years. On the bright side, this performance was better than its 3.4% annualized revenue growth and tells us the company became more profitable on a per-share basis as it expanded.
We can take a deeper look into A. O. Smith’s earnings to better understand the drivers of its performance. A five-year view shows that A. O. Smith has repurchased its stock, shrinking its share count by 14.8%. This tells us its EPS outperformed its revenue not because of increased operational efficiency but financial engineering, as buybacks boost per share earnings. 
Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.
