Company Overview

Growing from a small wire manufacturer to one of the largest in the U.S., Insteel (NYSE: IIIN) provides steel wire reinforcing products for concrete.

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. Unfortunately, Insteel’s 4.9% annualized revenue growth over the last five years was tepid. This was below our standard 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. Insteel’s annualized revenue growth of 13.2% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

This quarter, Insteel reported year-on-year revenue growth of 9.9%, and its $197.7 million of revenue exceeded Wall Street’s estimates by 2.9%.

Looking ahead, sell-side analysts expect revenue to grow 9.9% over the next 12 months, a deceleration versus the last two years. Still, this projection is healthy and suggests the market sees success for its products and services.

Operating Margin

Operating margin is a key measure of profitability. Think of it as net income - the bottom line - excluding the impact of taxes and interest on debt, which are less connected to business fundamentals.

Insteel has done a decent job managing its cost base over the last five years. The company has produced an average operating margin of 9.9%, higher than the broader industrials sector.

Looking at the trend in its profitability, Insteel’s operating margin decreased by 14 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.

In Q2, Insteel generated an operating margin profit margin of 5.9%, down 5.3 percentage points year on year. Since Insteel’s gross margin decreased more than its operating margin, we can assume its recent inefficiencies were driven more by weaker leverage on its cost of sales rather than increased marketing, R&D, and administrative overhead expenses.

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.

Sadly for Insteel, its EPS declined by 5.7% annually over the last five years while its revenue grew by 4.9%. This tells us the company became less profitable on a per-share basis as it expanded.

Diving into the nuances of Insteel’s earnings can give us a better understanding of its performance. As we mentioned earlier, Insteel’s operating margin declined by 14 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its lower earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.

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 Insteel, its two-year annual EPS growth of 33.7% was higher than its five-year trend. This acceleration made it one of the faster-growing industrials companies in recent history.

In Q2, Insteel reported EPS of $0.46, down from $0.78 in the same quarter last year. Despite falling year on year, this print beat analysts’ estimates by 3.4%. Over the next 12 months, Wall Street expects Insteel’s full-year EPS to grow 10.5% from $1.86 to $2.05.

We enjoyed seeing Insteel beat analysts’ revenue expectations this quarter. We were also glad its EPS outperformed Wall Street’s estimates. Overall, we think this was a decent quarter with some key metrics above expectations. The stock remained flat at $29.72 immediately following the results.

Big picture, is Insteel a buy here and now? The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy. We cover that in our actionable full research report which you can read here (it’s free).
