Company Overview
Established in 1901, Limbach (NASDAQ: LMB) provides integrated building systems solutions, including mechanical, electrical, and plumbing services.
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 the best consistently grow over the long haul. Regrettably, Limbach’s sales grew at a sluggish 3.8% compounded annual growth rate over the last five years. This wasn’t a great result compared to the rest of the industrials sector, but there are still things to like about Limbach.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Limbach’s annualized revenue growth of 12.6% over the last two years is above its five-year trend, suggesting its demand recently accelerated. 
This quarter, Limbach reported modest year-on-year revenue growth of 4.3% but beat Wall Street’s estimates by 3.5%.
Looking ahead, sell-side analysts expect revenue to grow 14.7% over the next 12 months, an improvement versus the last two years. This projection is noteworthy and implies 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.
Limbach was profitable over the last five years but held back by its large cost base. Its average operating margin of 5.7% was weak for an industrials business. This result isn’t too surprising given its low gross margin as a starting point.
On the plus side, Limbach’s operating margin rose by 4 percentage points over the last five years, as its sales growth gave it operating leverage.
In Q1, Limbach’s breakeven margin was 0.8%, down 5.4 percentage points year on year. Since Limbach’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.
Limbach’s EPS grew at 38.1% compounded annual growth rate over the last five years, higher than its 3.8% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
We can take a deeper look into Limbach’s earnings to better understand the drivers of its performance. As we mentioned earlier, Limbach’s operating margin declined this quarter but expanded by 4 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher 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 shorter period to see if we are missing a change in the business.
For Limbach, its two-year annual EPS growth of 29.1% was lower than its five-year trend. We still think its growth was good and hope it can accelerate in the future.
In Q1, Limbach reported adjusted EPS of $0.64, down from $1.12 in the same quarter last year. Despite falling year on year, this print easily cleared analysts’ estimates. Over the next 12 months, Wall Street expects Limbach’s full-year EPS of $4.02 to grow 12.2%.
Key Takeaways from Limbach’s Q1 Results
It was good to see Limbach beat analysts’ EPS expectations this quarter. We were also excited its adjusted operating income outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this quarter featured some important positives. The market seemed to be hoping for more, and the stock traded down 10.5% to $102.28 immediately following the results.
