Company Overview

With over 90 years of connecting the world's technologies, Amphenol (NYSE: APH) designs and manufactures connectors, cables, sensors, and interconnect systems that enable electrical and electronic connections across virtually every industry.

Electronic Components & Manufacturing

The sector could see higher demand as the prevalence of advanced electronics increases in industries such as automotive, healthcare, aerospace, and computing. The high-performance components and contract manufacturing expertise required for autonomous vehicles and cloud computing datacenters, for instance, will benefit companies in the space. However, headwinds include geopolitical risks, particularly U.S.-China trade tensions that could disrupt component sourcing and production as the Trump administration takes an increasingly antagonizing stance on foreign relations. Additionally, stringent environmental regulations on e-waste and emissions could force the industry to pivot in potentially costly ways.

Sales Growth

Examining a company’s long-term performance can provide clues about its quality. Any business can have short-term success, but a top-tier one grows for years.

With $16.78 billion in revenue over the past 12 months, Amphenol is a behemoth in the business services sector and benefits from economies of scale, giving it an edge in distribution. This also enables it to gain more leverage on its fixed costs than smaller competitors and the flexibility to offer lower prices.

As you can see below, Amphenol’s 15.6% annualized revenue growth over the last five years was incredible. This is a great starting point for our analysis because it shows Amphenol’s demand was higher than many business services companies.

Long-term growth is the most important, but within business services, a half-decade historical view may miss new innovations or demand cycles. Amphenol’s annualized revenue growth of 15.2% over the last two years aligns with its five-year trend, suggesting its demand was predictably strong. Amphenol Year-On-Year Revenue Growth

This quarter, Amphenol reported magnificent year-on-year revenue growth of 47.7%, and its $4.81 billion of revenue beat Wall Street’s estimates by 13%. Company management is currently guiding for a 37.1% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 13.5% over the next 12 months, a slight deceleration versus the last two years. Still, this projection is eye-popping given its scale and indicates the market is baking in success for its products and services.

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.

Amphenol has been a well-oiled machine over the last five years. It demonstrated elite profitability for a business services business, boasting an average operating margin of 20.3%.

Looking at the trend in its profitability, Amphenol’s operating margin rose by 1.2 percentage points over the last five years, as its sales growth gave it operating leverage.

Amphenol Trailing 12-Month Operating Margin (GAAP)

In Q1, Amphenol generated an operating profit margin of 21.3%, in line with the same quarter last year. This indicates the company’s overall cost structure has been relatively 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.

Amphenol’s EPS grew at an astounding 18.9% compounded annual growth rate over the last five years, higher than its 15.6% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

Amphenol Trailing 12-Month EPS (Non-GAAP)

Diving into the nuances of Amphenol’s earnings can give us a better understanding of its performance. As we mentioned earlier, Amphenol’s operating margin was flat this quarter but expanded by 1.2 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; taxes and interest expenses can also affect EPS but don’t tell us as much about a company’s fundamentals.

In Q1, Amphenol reported EPS at $0.63, up from $0.40 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 Amphenol’s full-year EPS of $2.12 to grow 12.4%.

Key Takeaways from Amphenol’s Q1 Results

We were impressed by how significantly Amphenol blew past analysts’ revenue and EPS expectations this quarter.

Indeed, Amphenol had a rock-solid quarterly earnings result, but is this stock a good investment here?
