Company Overview

The developer of the first blade-type automotive fuse, Littelfuse (NASDAQ: LFUS) provides electrical protection and control components for the automotive, industrial, electronics, and telecommunications 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 many enduring ones grow for years. Luckily, Littelfuse’s sales grew at a decent 8% compounded annual growth rate over the last five years. Its growth was slightly above 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. Littelfuse’s annualized revenue growth of 8.2% over the last two years aligns with its five-year trend, suggesting its demand was stable.

We can dig further into the company’s revenue dynamics by analyzing its most important segments, Electronics and Automotive, which are 55% and 24.7% of revenue. Over the last two years, Littelfuse’s Electronics revenue (fuses and switches) averaged 15.5% year-on-year growth while its Automotive revenue (trucks, commercial machinery, marine) averaged 1.6% growth.

This quarter, Littelfuse reported robust year-on-year revenue growth of 20.4%, and its $738.8 million of revenue topped Wall Street estimates by 5.4%.

Looking ahead, sell-side analysts expect revenue to grow 6% over the next 12 months, a slight deceleration versus the last two years. This projection doesn’t excite us and indicates its products and services will see some demand headwinds.

Operating Margin

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.

Littelfuse 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 12.5%. This result isn’t surprising as its high gross margin gives it a favorable starting point.

Looking at the trend in its profitability, Littelfuse’s operating margin decreased by 17.7 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.

This quarter, Littelfuse generated an operating margin profit margin of 16.2%, up 1.1 percentage points year on year. Since its gross margin expanded more than its operating margin, we can infer that leverage on its cost of sales was the primary driver behind the recently higher efficiency.

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.

Littelfuse’s EPS grew at an unimpressive 4.6% compounded annual growth rate over the last five years, lower than its 8% annualized revenue growth. This tells us the company became less profitable on a per-share basis as it expanded.

Diving into the nuances of Littelfuse’s earnings can give us a better understanding of its performance. As we mentioned earlier, Littelfuse’s operating margin expanded this quarter but declined by 17.7 percentage points over the last five years. Its share count also grew by 2.9%, meaning the company not only became less efficient with its operating expenses but also diluted its shareholders.

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 Littelfuse, its two-year annual EPS growth of 22.8% was higher than its five-year trend. This acceleration made it one of the faster-growing industrials companies in recent history.

In Q2, Littelfuse reported adjusted EPS of $4.19, up from $2.85 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 Littelfuse’s full-year EPS to grow 17.4% from $13.14 to $15.43.

Key Takeaways from Littelfuse’s Q2 Results

We were impressed by how significantly Littelfuse blew past analysts’ EBITDA expectations this quarter. We were also excited its revenue outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this quarter featured some important positives. The stock traded up 11.7% to $438.07 immediately after reporting.

Littelfuse 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. If you’re making that decision, you should consider the bigger picture of valuation, business qualities, as well as the latest earnings.
