Company Overview

Gibraltar (NASDAQ: ROCK) makes renewable energy, agriculture technology and infrastructure products. Its mission statement is to make everyday living more sustainable.

Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Regrettably, Gibraltar’s sales grew at a sluggish 2.4% compounded annual growth rate over the last five years. This was below our standards and is a rough 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. Gibraltar’s performance shows it grew in the past but relinquished its gains over the last two years, as its revenue fell by 3.1% annually.

This quarter, Gibraltar reported magnificent year-on-year revenue growth of 44.6%, and its $356.3 million of revenue beat Wall Street’s estimates by 1.8%.

Looking ahead, sell-side analysts expect revenue to grow 59.1% over the next 12 months, an improvement versus the last two years. This projection is eye-popping and indicates its newer products and services will fuel better top-line performance.

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.

Gibraltar’s operating margin has generally stayed the same over the last 12 months, averaging 10.8% over the last five years. This profitability was solid for an industrials business and shows it’s an efficient company that manages its expenses well. This result was particularly impressive because of its low gross margin, which is mostly a factor of what it sells and takes huge shifts to move meaningfully. Companies have more control over their operating margins, and it’s a show of well-managed operations if they’re high when gross margins are low.

Looking at the trend in its profitability, Gibraltar’s operating margin might fluctuated slightly but has generally stayed the same 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 Q1, Gibraltar generated an operating margin profit margin of negative 1.3%, down 14.4 percentage points year on year. Since Gibraltar’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.

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.

Gibraltar’s weak 2.9% 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 more recent period because it can provide insight into an emerging theme or development for the business.

Gibraltar’s two-year annual EPS declines of 9.1% were bad and lower than its two-year revenue losses.

We can take a deeper look into Gibraltar’s earnings to better understand the drivers of its performance. Gibraltar’s operating margin has declined over the last two 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.

In Q1, Gibraltar reported adjusted EPS of $0.45, down from $0.95 in the same quarter last year. This print missed analysts’ estimates. We also like to analyze expected EPS growth based on Wall Street analysts’ consensus projections, but there is insufficient data.

Key Takeaways from Gibraltar’s Q1 Results

It was great to see Gibraltar’s full-year EPS guidance top analysts’ expectations. We were also glad its full-year revenue guidance exceeded Wall Street’s estimates. On the other hand, its adjusted operating income missed and its EBITDA fell short of Wall Street’s estimates. Overall, this was a weaker quarter. The stock traded down 5.6% to $35.77 immediately after reporting.

Gibraltar didn’t show it’s best hand this quarter, but does that create an opportunity to buy the stock right now? If you’re making that decision, you should consider the bigger picture of valuation, business qualities, as well as the latest earnings.
