Revenue Growth

Examining a company’s long-term performance can provide clues about its quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Regrettably, Owens Corning’s sales grew at a sluggish 4.3% compounded annual growth rate over the last five years. This was below our standard 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. Owens Corning’s recent performance shows its demand has slowed as its annualized revenue growth of 2.9% 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.

This quarter, Owens Corning’s $2.76 billion of revenue was flat year on year but beat Wall Street’s estimates by 4%. Company management is currently guiding for a 1.3% year-on-year decline in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 2.8% over the next 12 months, similar to its two-year rate. This projection is underwhelming and suggests its newer products and services will not catalyze 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.

Owens Corning 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 13.7%. This result was particularly impressive because of its low gross margin, which is mostly a factor of what it sells and takes huge shifts to move meaningfully. Companies have more control over their operating margins, and it’s a show of well-managed operations if they’re high when gross margins are low.

Looking at the trend in its profitability, Owens Corning’s operating margin decreased by 17.2 percentage points 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.

In Q2, Owens Corning generated an operating margin profit margin of 17.5%, in line with the same quarter last year. This indicates the company’s cost structure has recently been stable.

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.

Owens Corning’s unimpressive 4.6% 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.

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.

For Owens Corning, its two-year annual EPS declines of 20.2% show it’s continued to underperform. These results were bad no matter how you slice the data.

In Q2, Owens Corning reported adjusted EPS of $3.93, down from $4.21 in the same quarter last year. Despite falling year on year, this print easily cleared analysts’ estimates. Over the next 12 months, Wall Street expects Owens Corning’s full-year EPS to grow 10.6% from $9.92 to $10.97.

Key Takeaways from Owens Corning’s Q2 Results

It was good to see Owens Corning beat analysts’ EPS expectations this quarter. We were also excited its EBITDA outperformed Wall Street’s estimates by a wide margin. On the other hand, its revenue guidance for next quarter slightly missed. Zooming out, we think this was a solid print. The stock traded up 3.7% to $150.93 immediately after reporting.

Owens Corning put up rock-solid earnings, but one quarter doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy.
