Revenue Growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Unfortunately, L.B. Foster’s 2% annualized revenue growth over the last five years was sluggish. This was below our standards and is a tough 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. L.B. Foster’s annualized revenue growth of 1.2% over the last two years aligns with its five-year trend, suggesting its demand was consistently weak.

L.B. Foster also reports its backlog, or the value of its outstanding orders that have not yet been executed or delivered. L.B. Foster’s backlog reached $246.1 million in the latest quarter and was flat over the last two years. Because this number is in line with its revenue growth, we can see the company effectively balanced its new order intake and fulfillment processes.

This quarter, L.B. Foster’s revenue fell by 3.5% year on year to $138.6 million but beat Wall Street’s estimates by 3%.

Looking ahead, sell-side analysts expect revenue to grow 2.4% over the next 12 months, similar to its two-year rate. Although this projection indicates its newer products and services will fuel better top-line performance, it is still below average for the sector.

Operating Margin

L.B. Foster was profitable over the last five years but held back by its large cost base. Its average operating margin of 2.6% 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, L.B. Foster’s operating margin rose by 4.7 percentage points over the last five years, as its sales growth gave it operating leverage.

This quarter, L.B. Foster generated an operating margin profit margin of 4.4%, down 1.8 percentage points year on year. Since L.B. Foster’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

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.

L.B. Foster’s weak 1.2% annual EPS growth over the last five years aligns with its revenue performance. On the bright side, this tells us its incremental sales were profitable.

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.
