Company Overview

Supplying windows for some of the United States’s earliest spacecraft, Corning (NYSE: GLW) provides glass and other electronic components for the consumer electronics, telecommunications, automotive, and healthcare industries.

Revenue Growth

Examining a company’s long-term performance can provide clues about its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Over the last five years, Corning grew its sales at a mediocre 6.7% compounded annual growth rate. This wasn’t a great result compared to the rest of the industrials sector, but there are still things to like about Corning.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Corning’s annualized revenue growth of 11.9% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

This quarter, Corning’s revenue grew by 12.6% year on year to $4.14 billion but fell short of Wall Street’s estimates. Company management is currently guiding for a 13.7% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 16.5% over the next 12 months, an improvement versus the last two years. This projection is eye-popping for a company of its scale and implies its newer products and services will catalyze better top-line performance.

Operating Margin

Corning’s operating margin has been trending up over the last 12 months and averaged 10.8% over the last five years. Its solid profitability for an industrials business shows it’s an efficient company that manages its expenses effectively. This result isn’t surprising as its high gross margin gives it a favorable starting point.

Looking at the trend in its profitability, Corning’s operating margin might 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.

In Q1, Corning generated an operating margin profit margin of 15.4%, up 3.3 percentage points year on year. The increase was encouraging, and because its gross margin actually decreased, we can assume it was more efficient because its operating expenses like marketing, R&D, and administrative overhead grew slower than its revenue.

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.

Corning’s EPS grew at 10.3% compounded annual growth rate over the last five years, higher than its 6.7% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its operating margin didn’t improve.

We can take a deeper look into Corning’s earnings quality to better understand the drivers of its performance. A five-year view shows that Corning has repurchased its stock, shrinking its share count by 3%. 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.

For Corning, its two-year annual EPS growth of 26.9% was higher than its five-year trend. We love it when earnings growth accelerates, especially when it accelerates off an already high base.

In Q1, Corning reported adjusted EPS of $0.70, up from $0.54 in the same quarter last year. This print beat analysts’ estimates by 1.2%. Over the next 12 months, Wall Street expects Corning’s full-year EPS of $2.69 to grow 21.6%.

Key Takeaways from Corning’s Q1 Results

We struggled to find many positives in these results. Its revenue missed and its adjusted operating income fell short of Wall Street’s estimates. Overall, this was a softer quarter. The stock traded down 9.6% to $152.57 immediately after reporting.

Corning’s latest earnings report disappointed. One quarter doesn’t define a company’s quality, so let’s explore whether the stock is a buy at the current price. When making that decision, it’s important to consider its valuation, business qualities, as well as what has happened in the latest quarter.
