Company Overview

Supplying parts for nearly all aircraft currently in service, TransDigm (NYSE: TDG) develops and manufactures components and systems for military and commercial aviation.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Thankfully, TransDigm’s 16.4% annualized revenue growth over the last five years was incredible. Its growth surpassed the average industrials company and shows its offerings resonate with customers, a great 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. TransDigm’s annualized revenue growth of 14.7% over the last two years is below its five-year trend, but we still think the results suggest healthy demand.

TransDigm also reports organic revenue, which strips out one-time events like acquisitions and currency fluctuations that don’t accurately reflect its fundamentals. Over the last two years, TransDigm’s organic revenue averaged 9.3% year-on-year growth. Because this number is lower than its two-year revenue growth, we can see that some mixture of acquisitions and foreign exchange rates boosted its headline results.

This quarter, TransDigm reported robust year-on-year revenue growth of 22.5%, and its $2.74 billion of revenue topped Wall Street estimates by 2.5%.

Looking ahead, sell-side analysts expect revenue to grow 12.5% over the next 12 months, a slight deceleration versus the last two years. We still think its growth trajectory is attractive given its scale and indicates the market sees success for its products and services.

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.

TransDigm has been a well-oiled machine over the last five years. It demonstrated elite profitability for an industrials business, boasting an average operating margin of 44.7%.

Looking at the trend in its profitability, TransDigm’s operating margin rose by 5.5 percentage points over the last five years, as its sales growth gave it immense operating leverage.

In Q2, TransDigm generated an operating margin profit margin of 44.8%, down 1.7 percentage points year on year. This reduction is quite minuscule and indicates the company’s overall cost structure has been relatively stable.

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.

TransDigm’s EPS grew at 29.9% compounded annual growth rate over the last five years, higher than its 16.4% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

Diving into the nuances of TransDigm’s earnings can give us a better understanding of its performance. As we mentioned earlier, TransDigm’s operating margin declined this quarter but expanded by 5.5 percentage points over the last five years. Its share count also shrank by 1.7%, and these factors together are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth.

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 TransDigm, its two-year annual EPS growth of 11.2% was lower than its five-year trend. We still think its growth was good and hope it can accelerate in the future.

In Q2, TransDigm reported adjusted EPS of $10.87, up from $9.60 in the same quarter last year. This print beat analysts’ estimates by 5.2%. Over the next 12 months, Wall Street expects TransDigm’s full-year EPS to grow 15.7% from $39.77 to $46.02.
