Company Overview

California’s oldest company, Ducommun (NYSE: DCO) is a provider of engineering and manufacturing services for high-performance products primarily within the aerospace and defense industries.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Regrettably, Ducommun’s sales grew at a mediocre 6.5% compounded annual growth rate over the last five years. This fell short of our benchmark for the industrials sector and is a poor baseline 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. Ducommun’s recent performance shows its demand has slowed as its annualized revenue growth of 4.7% 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, Ducommun reported year-on-year revenue growth of 7.7%, and its $209 million of revenue exceeded Wall Street’s estimates by 4.8%.

Looking ahead, sell-side analysts expect revenue to grow 7.9% over the next 12 months, an improvement versus the last two years. This projection is above the sector average and suggests its newer products and services will catalyze better top-line performance.

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.

Ducommun was profitable over the last five years but held back by its large cost base. Its average operating margin of 3.8% was weak for an industrials business.

Analyzing the trend in its profitability, Ducommun’s operating margin decreased by 11.2 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. Ducommun’s performance was poor no matter how you look at it - it shows that costs were rising and it couldn’t pass them onto its customers.

In Q1, Ducommun generated an operating margin profit margin of 7.5%, down 1 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.

Ducommun’s unimpressive 6.8% 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 shorter period to see if we are missing a change in the business.

For Ducommun, its two-year annual EPS growth of 17.9% was higher than its five-year trend. This acceleration made it one of the faster-growing industrials companies in recent history.

In Q1, Ducommun reported adjusted EPS of $0.75, down from $0.83 in the same quarter last year. Despite falling year on year, this print beat analysts’ estimates by 4%. Over the next 12 months, Wall Street expects Ducommun’s full-year EPS of $3.67 to grow 25%.
